254 case-sensitive for printer and class names, so
255 queue-specific access control was not reliable (STR

581 - The scheduler did not support requests with more than
582 one language specified (STR #267)
585 CHANGES IN CUPS V1.1.20rc1

590 - The web interface did not work on systems where time_t
591 is 64 bits (STR #262)
592 - Added backend tweeks and content-length check from Red
594 - The USB backend now uses the 8255 constants instead of
595 the standard constants when reporting printer status
596 bits on Linux (STR #254)
597 - Added new cupsDoAuthentication(), cupsGetFd(),
598 cupsGetFile(), cupsPutFd(), and cupsPutFile() functions
599 to the CUPS API (STR #112)
600 - The PDF filter always scaled and offset pages; this
601 caused problems under MacOS X, so now the "fitplot"
602 option controls whether PDF files are scaled to fit
603 within the printable area of the page (STR #250)
604 - The LPD backend did not support the port number in a
606 - Some filters didn't properly support boolean options
608 - Landscape PDF files were not always offset by the
609 correct amount when rotating (STR #243)
610 - The scheduler could hang in a call to localtime() when
611 logging messages from the signal handler (STR #242)
612 - The PDF filter no longer prints form widgets; this
613 duplicates the behavior of Acrobat Reader (STR #241)
614 - cupsGetPPD() didn't handle a late termination of a
615 HTTP connection with the server (STR #220)
616 - ppdOpen() did not correctly check for "*PPD-Adobe-4."
617 on the first line of a PPD file. This caused incorrect
618 PASS results for some PPD files (STR #233)
619 - cupsEncodeOptions() did not allow boolean options to
620 use "yes" and "on" for true values (STR #227)
621 - The pstops filter only sent the TBCP exit sequence if
622 it was defined in the JCLEnd attribute in the PPD file
624 - Support for more than 1024 files was broken on Solaris
626 - The setgroups() calls now pass in 1 group (the
627 configured group) instead of 0 for compatibility with
628 BSD and Darwin (STR #213)
629 - The scheduler's built-in broadcast throttling was
630 ineffective since incoming packets would cause the
631 next group of outgoing packets to be sent immediately
632 rather than waiting for the next time slot (STR #211)
633 - Added a new ppdSetConformance() function to set the
634 conformance requirements for PPD files. Currently only
635 two levels are defined, PPD_CONFORM_RELAXED and
636 PPD_CONFORM_STRICT, and the default is the relaxed
638 - The IPP backend did not correctly execute the
639 pictwpstops filter on OSX (STR #210)
640 - The LPD backend did not set the banner class when the
641 "banner=yes" option was specified in the device URI
643 - The imagetoraster filter did not support all of the
644 page device attributes (STR #208)
645 - The pdftops filter incorrectly auto-rotated pages when
646 the user already had specified the proper orientation
648 - Fixed AIX shared library support (STR #201)
649 - Added support for live testing with Valgrind (STR
651 - The CGI programs now collect the list of needed
652 attributes for the class, job, and printer template
654 - The scheduler now passes the first port that is bound
655 to the local loopback or "any" addresses to the CGI
656 programs rather than the port that the browser
657 connected to (STR #103)
658 - The cupstestppd program now checks for bad
659 JobPatchFile attributes and incorrect versions of the
660 Manufacturer attribute for HP printers (STR #155)
661 - The filter makefile incorrectly installed
662 libcupsimage.a in the filter directory (STR #180)
663 - The scheduler did not verify that the job history
664 files define the job-priority and
665 job-originating-user-name attributes (STR #178)
666 - The pstops filter didn't handle poorly-formed binary
667 PostScript files that had CTRL-D's in them (STR #156)
668 - The ppdOpen*() and cupsLangGet() functions did not
669 make a copy of the old locale strings when using the
670 POSIX locale when reading files, which apparently
671 caused problems with some implementations of the
672 standard C library. (STR #159)
673 - The pdftops filter did not work properly with some
674 embedded Type1C fonts (STR #177)
675 - Updated the pdftops filter to be based upon Xpdf
677 - The scheduler did not reset the group list when
678 running CGI and filter processes (STR #185)
679 - The scheduler no longer calls malloc and free from the
680 signal handlers (STR #190)
681 - The USB backend now uses the manufacturer and model
682 strings if the description string is not available
684 - The ppdOpen functions still supported the
685 VariablePaperSize attribute, which was removed in v4.0
686 of the PPD spec. This caused problems with PPD files
687 that relocated the PageSize option to a non-standard
689 - The cups.list file referenced MAN1EXT, MAN3EXT, and
690 MAN5EXT, but none of those were actually defined (STR
692 - Chunked requests could cause a Denial of Service if
693 the connection is terminated before the first byte of
694 chunk data is sent/received (STR #143)
695 - Printers with special characters in their names were
696 not accessible from the web interface (STR #120)
697 - The lpstat command now shows the correct interface
698 script or PPD file, if any, for a print queue (STR #89)
699 - The lpstat command now shows the printer-state-message
700 and printer-state-reasons attributes whenever they are
702 - The French and German option-conflict.tmpl template
703 files did not get installed (STR #148)
704 - The cups.list.in file did not work when compiling
705 without shared libraries (STR #149)
706 - The DSOFLAGS included the LDFLAGS, which causes
707 problems on at least HP-UX (STR #150)
708 - The fax printer support did not keep track of the fax
709 capability bit (STR #144)
710 - The appleLangDefault() function could leak a small
711 amount of memory (STR #145)
712 - The ppdOpen() functions now mirror all normal
713 attributes to the attribute list; previously only
714 certain unassigned attributes would be added (STR
716 - The ppdEmitJCL() function wrote JCL commands to stdout
717 instead of the passed file pointer (STR #142)
718 - The httpGets() function could, in certain states,
719 block waiting for data (STR #132)
720 - The cupsEmitJCL() function not outputs an empty @PJL
721 command after the PJL language escape to work around
722 bugs in certain PJL implementations (STR #131)
723 - The cupsEmit*() functions didn't set the orientation
724 value properly (STR #127)
725 - The cups.spec file didn't list the rc2.d init
726 directory or the cupstestppd file (STR #134)
729 CHANGES IN CUPS V1.1.19
731 - The GNU TLS code incorrectly used
732 gnutls_check_pending() instead of
733 gnutls_record_check_pending() (STR #128)
734 - The ppdEmit() functions output "PageSize Custom"
735 instead of "CustomPageSize True" in the DSC comments.
736 Also, the custom page size code did not use the
737 ParamCustomPageSize attributes (STR #127)
738 - The cupstestppd command did not list the conflicting
740 - The lpq command did not ensure that there was
741 whitespace between the fields in the job listing (STR
743 - The German web templates had errors (STR #119)
744 - The configure script didn't specify the static
745 libraries properly when configuring with the
746 --disable-shared option (STR #104)
747 - The cups.list file used file dependencies for package
748 formats other than portable, RPM, and Debian (STR #98)
749 - cupsLangGet() didn't use its language cache (STR #97)
750 - "lpq -P" would segfault instead of showing a usage
752 - Fixed compiler warnings in pdftops filter (STR #96)
755 CHANGES IN CUPS V1.1.19rc5
757 - Jobs with banner pages that were printed to implicit
758 classes would get double banner pages for each
759 file/banner in the job (STR #68)
760 - The mime.convs file was missing the filter definition
761 for Windows BMP (image/x-bitmap) files (STR #85)
762 - The scheduler allowed some READ-ONLY job attributes to
763 be set, which could cause the scheduler to fail on the
764 next restart (STR #82)
765 - The lp and lpr commands did not report when the
766 scheduler was not responding; instead, the user would
767 incorrectly see a "no default destination" error (STR
769 - cupsLangGet() could fail on OSX due to a corrupt
770 language preference (STR #78)
771 - Added more checks for HTTP request timeouts.
772 - The scheduler dropped the first non-alpha character
773 after an open brace when doing attribute substitutions
774 in banner pages (STR #77)
775 - The scheduler child might send SIGUSR1 to the parent
776 before the signal handler was installed; this didn't
777 prevent the scheduler from starting but produced an
778 annoying error message (STR #45)
781 CHANGES IN CUPS V1.1.19rc4
783 - The lp command did not accept "-" for printing from
784 the standard input as required by POSIX 1003.1 (STR
786 - Added the job-originating-host-name information for
787 the page_log file documentation in the SAM (STR #31)
788 - The German web interface templates did not use the
789 right paths for job operations (STR #54)
790 - The scheduler would consume all available CPU if
791 started with a pending job in the queue (STR #35)
792 - The polling daemon allocated an extra localization
793 buffer but did not free it, causing cups-polld to
794 eventually use all available memory (STR #40)
797 CHANGES IN CUPS V1.1.19rc3
799 - The scheduler could get in an infinite loop cancelling
800 jobs using "cancel -u user dest" (STR #48)
801 - The "cancel -u user" command did nothing (it should
802 cancel all jobs on all printers owned by the named
804 - The scheduler would write 0-length job control files
806 - Updated the French man pages (translation provided by
808 - The scheduler would delete all printers from
809 printers.conf if a job was active when a HUP signal
810 was handled (STR #47)
811 - The cups-polld program would leak memory if it was
812 unable to send browse packets to the loopback
814 - The scheduler did not put the
815 job-originating-host-name attribute in the job
817 - The text filter did not default to wrapping text as
818 defined by the IPP implementation document.
819 - Scan backends first, PPDs second (STR #37)
820 - Updated the Netatalk documentation in the SAM (STR #38
822 - The test suite sent text files to a non-PS print queue,
823 which requires ESP Ghostscript (provided separately).
824 Now send the JPEG test file (STR #33)
825 - The test suite did not show the estimated disk space
826 requirements (STR #33)
827 - The test suite did not set the MaxLogSize directive to
828 0 to prevent log file rotation (STR #33)
829 - The test suite still setup the old CUPS Ghostscript
831 - The pstops filter did not report the correct number of
832 copies for the page_log file when printing collated
833 copies to a printer that doesn't support them in
835 - cupsLangGet() needs to set the CTYPE locale to "C"
836 (POSIX) to avoid erroneous tolower/toupper values (fix
837 suggested by Bjoern Jacke)
838 - Fixed a typo in the cups.list.in file.
839 - Updated all of the Western European locales to default
840 to ISO-8859-15 (for Euro support, suggested by Bjoern
842 - Updated the German message catalog (update provided by
846 CHANGES IN CUPS V1.1.19rc2
848 - cupsLangGet() now sets the encoding field based on the
849 trailing charset in the locale name, and doesn't look
850 for a message catalog in a specific locale.charset
851 directory. This fixes STR #26 and is more in line
852 with the CUPS 1.2 implementation.
853 - The configure script now aborts if the "ar" command or
854 compilers cannot be found.
855 - The static cupsimage library was not built by default.
856 - The path for the "ln" command was hardcoded in
857 Makedefs.in instead of being checked at configure time
859 - Banner pages containing unescaped { characters would
861 - The printer-state-time collection attribute was
862 encoded as an enumeration instead of an integer.
863 - The printer-is-accepting-jobs collection attribute was
864 was not added to the collection value.
865 - The printer-state-sequence-number collection attribute
866 was not added to the collection value.
867 - Fixed typo and const mismatch in IPP backend.
868 - Updated the man pages for the new configuration
870 - Updated the SAM for MacOS 10.2, the CUPS drivers for
871 windows, the available LPD backend options, and the
872 new configuration directives.
873 - The imagetops filter didn't position images properly
874 on the page (STR #18)
875 - The configure script didn't add CPPFLAGS to the
876 compiler options or LDFLAGS to the DSO options (STR
878 - The scheduler would try to write a debug log message
879 when starting a job that contained a NULL string.
880 Since not all versions of snprintf() support NULL
881 string pointers this caused some problems (STR #20)
882 - The testipp program now supports reading of IPP
883 message files such as those used for the job history
887 CHANGES IN CUPS V1.1.19rc1
889 - Added CUPS support files for Java, Perl, and PHP
890 (located in the "scripting" subdirectory...)
891 - The scheduler now supports fast-reloads of the
892 cupsd.conf file when it is updated via HTTP.
893 - The scheduler always changed the ownership of log
894 files; it now only does so if they are not in the /dev
895 directory (i.e. don't want to change the ownership and
896 permissions of /dev/null...)
897 - Added libpaper support (patch from Jeff Licquia)
898 - Added a new istring() rule for MIME types files that
899 does a case-insensitive comparison of strings.
900 - The cups-lpd mini-daemon now sends jobs to the default
901 queue when an empty queue name (or "lp" and there is
902 no "lp" queue) is sent.
903 - The scheduler now supports fax queues identified by a
904 "*cupsFax: True" attribute in the PPD file. When a job
905 can't be sent, it is held for 5 minutes by default
906 while other jobs are attempted. The FaxRetryLimit and
907 FaxRetryInterval directives control the number of
908 retries and the time between retries.
909 - The scheduler now preserves the default options of PPD
910 files when modifying/upgrading an existing PPD file.
911 When installing a new printer, the scheduler sets the
912 default media size to Letter or A4 as appropriate for
914 - The scheduler no longer limits the number of
915 BrowseAddress, BrowsePoll, BrowseRelay, Listen, Port,
916 SSLListen, and SSLPort directives to 10.
917 - The scheduler now supports print files that have been
918 compressed using gzip.
919 - The scheduler used the stdio functions to read any job
920 ticket information in a PostScript print job. Since
921 some platforms limit the number of stdio files to 256,
922 job ticket information was ignored when the server had
923 a large number of clients connected to the system.
924 - Filters and backends may now report the total number
925 of pages ("PAGE: total NNN") to the scheduler.
926 - The LPD backend now supports timeout and
927 sanitize_title options (default to 300 and yes,
928 respectively) and has some additional changes to
929 reduce the chances of multiple copies being printed
930 when only one copy was requested.
931 - Fixed a polygon drawing bug in the HP-GL/2 filter.
932 - Added a robots.txt file to the standard install to
933 prevent search engines from indexing the CUPS server.
934 - Added support for STATE: messages
935 (printer-state-reasons), printer-state-history, and
936 printer-state-time to the scheduler.
937 - When using RunAsUser, the scheduler would initially
938 start any previously queued (pending) jobs with
939 RunAsUser disabled - all backends would be running as
941 - If a backend failed for a printer, CUPS would
942 incorrectly requeue the job for printing again.
943 - Added support for IPP collections and files.
944 - Added experimental support for generic CGI scripts and
945 programs, Java, Perl, PHP, and Python to the
946 scheduler. See the file "CGI.txt" for more
948 - The CUPS API now supports HTTP cookies and the Expect:
950 - The cancel command now correctly supports the "-u
951 user" option to cancel all jobs for the named user.
952 - The Purge-Jobs operation now supports the my-jobs
953 boolean attribute and a new purge-jobs boolean
954 attribute to control whether job history data is
955 purged from the scheduler; the default is false for
956 my-jobs and true for purge-jobs to match the original
958 - The scheduler would not timeout printers when only
960 - If the scheduler was unable to execute a filter, it
961 would try to restart the job indefinitely until the
962 filter could be executed.
963 - When writing BSD printcap files, the scheduler now
964 includes the rm and rp attributes, allowing the file
965 to be exported to LPD clients. [Patch from Dominic
967 - The scheduler optimization to reference IPP attribute
968 data instead of performing a full copy caused problems
969 when the referenced data was deleted before it was
970 sent. It now only references attributes that change
971 only when the scheduler is restarted. The change also
972 reduced the memory footprint of a printer object to
974 - The scheduler now holds signals while logging messages
975 to avoid potential deadlock issues when handling
976 signals on Solaris 8.
977 - The lpadmin command now allows printer access control
978 by group name as well as user name.
979 - "lpoptions -l" got in an infinite loop if no default
980 printer was available.
981 - The scheduler now logs the job-originating-host-name
982 attribute in the page_log file, and uses "-" for any
983 empty fields (patch from Dominik Kubla).
984 - The pdftops filter now scales PDF pages within the
985 printable area of the page.
986 - The pstops filter didn't include the page-label and
987 classification boxes when printing EPS or non-
989 - The imagetops filter didn't always correctly position
990 the image on the page when printing in landscape
992 - The ppdEmit() functions now support the
993 RequiresPageRegion attribute when sending InputSlot
994 and ManualFeed commands.
995 - The PPD loading code now supports standard options
996 outside of OpenUI/CloseUI as required by the PPD spec.
997 - The cupstestppd program has been upgraded to provide a
998 concise PASS/FAIL report, additional detailed
999 conformance testing, and support for gzip'd PPD files.
1000 - The PPD loading code is now much more strict when
1001 loading a PPD file, and tracks more format errors.
1002 - The scheduler ignored child signals when gathering the
1003 list of available devices, when it should have been
1004 using the default signal handler.
1005 - The cupsEncodeOptions() function could encode an
1006 option with a NULL last string.
1007 - The socket backend could report the wrong number of
1008 backchannel bytes if an error occurred on the link.
1009 - The cups-polld program now only sleeps after getting
1010 all printers and classes. This allows for longer
1011 intervals without excessive delays before classes show
1013 - Added a new httpWait() function to support waiting for
1014 data for a specific number of milliseconds.
1015 - httpGets() now times out after 1 second on
1016 non-blocking HTTP connections.
1017 - The scheduler no longer accepts rangeOfInteger values
1018 that are out of order (e.g. 5-1)
1019 - The sides attribute was incorrectly sent as a name
1020 value; it is a keyword value.
1021 - The IPP backend now detects if the destination queue
1022 has gone away and reports an error.
1023 - The scheduler and HTTP API now allocate their select()
1024 sets to support larger numbers of clients on systems
1026 - The scheduler now sets the CFProcessPath environment
1027 variable under MacOS X.
1028 - The cupsLangDefault() function now uses the
1029 CoreFoundation localization API under MacOS X.
1030 - The httpSeparate() function didn't handle file URIs of
1031 the form "file:///path" properly.
1032 - The lpadmin command now supports a "protocol" option
1033 for specifying the binary communications protocol to
1034 use when printing binary PostScript data.
1035 - The scheduler did not properly parse the SystemGroup
1036 directive, so only the first group would be used.
1037 - Revamped how strings are stored in the scheduler,
1038 providing a substantial improvement in memory usage
1039 for systems with large numbers of printers.
1040 - The PostScript filter now supports binary PostScript
1041 files and files beginning with the PJL language escape
1043 - The PPD API now provides additional information from
1045 - The USB backend didn't compile on Solaris Intel.
1046 - The cupstestppd utility now supports the "-q" option
1047 (quiet) for use in scripts, etc.
1048 - Merged several weight-reducing changes into the CUPS
1049 baseline donated by Apple.
1050 - Added preliminary support for CDSA; patch provided by
1052 - Implicit classes are now created from identical
1053 printer classes on the network.
1054 - The lp command now supports a "-H restart" option to
1055 restart previously printed jobs. This functionality
1056 only works if you have enabled the PreserveJobFiles
1058 - The scheduler now supports URIs in HTTP request lines
1059 to conform to the HTTP/1.1 specification.
1060 - The time-at-xyz attributes were not recognized in
1061 banner files if prefixed by a question mark, e.g.
1062 "{?time-at-creation}".
1063 - Added support for pre-filtering application/pictwps
1064 files on MacOS clients before sending them to a server
1066 - The scheduler now allows file:/dev/null device URIs
1067 even if FileDevices is set to No.
1068 - CUPS uses strerror() for hostname resolution errors,
1069 when it should have used hstrerror().
1070 - The USB backend no longer tries to guess the serial
1071 number of a device from the USB devices file; this
1072 means that printers that don't report their serial
1073 numbers in the device ID string will not be
1074 individually selectable.
1075 - The pstops filter didn't handle page ranges properly
1076 when a page contained an embedded document.
1077 - Added a translation of the web interface to German.
1078 - When printing using the OutputOrder=Reverse option
1079 with duplexing, the output order is now truly
1080 reversed; the order of sub-pages when printing N-up is
1082 - The pstops filter did not always output the extra
1083 blank page when printing a document with an odd number
1084 of pages with duplexing enabled.
1085 - The ippAddXYZ functions no longer allow the
1086 application to add less than 1 value.
1087 - Fixed a URL rewrite bug in the web interface - local
1088 access was sometimes redirected away from localhost...
1089 - The ppdOpen() functions could get in an infinite loop
1090 if the PPD file contained a keyword or text that was
1091 too large for the buffer.
1092 - Added preliminary support for GNU TLS; patch provided
1094 - Now timeout IPP attribute reads after 1 second inside
1095 an attribute definition.
1096 - Now timeout connections that have been shutdown (due
1097 to errors) after 30 seconds instead of the Timeout
1098 setting (300 seconds by default). This provides
1099 faster recovery from DoS attacks.
1100 - A denial-of-service attack warning message was being
1101 written to the log files by the scheduler for every
1102 detection. This caused a DoS of its own in some
1103 situations. The warning message is now written no more
1104 than once per minute.
1105 - Fixed the CIE colorspace support code in the image and
1107 - The job-quota-period, job-page-limit, and job-k-limit
1108 attributes were not flagged as integers, so setting
1109 quotas would not work.
1110 - Added an additional response check in the scheduler to
1111 more quickly recover from denial-of-service attacks.
1112 - The cupstestppd file was incorrectly installed in the
1113 /usr/sbin directory instead of /usr/bin.
1114 - The EPM list file did not include the cupstestppd
1115 program or man page files.
1118 CHANGES IN CUPS V1.1.18
1120 - Fixed a bug in the Set-Job-Attributes code in the
1121 scheduler that would cause it to crash or continuously
1122 write a job control file.
1123 - SECURITY FIX: The scheduler now provides a FileDevice
1124 directive to control whether new printers can be added
1125 using device URIs of the form "file:/filename". The
1126 default is to not allow printers with these device
1128 - The scheduler did not compute the cost of filters
1129 properly, nor did it choose a multi-filter solution
1130 with a lower cost than a single filter solution.
1131 - Now install CUPS PPD file test utility (cupstestppd)
1132 to support basic conformance testing of PPD files.
1133 - The scheduler now logs an error message when it sees a
1134 non-conforming PPD file.
1135 - Upgraded pdftops filter to Xpdf 2.01 with fixes for
1137 - Added a MaxClientsPerHost configuration directive to
1138 provide limited protection against Denial of Service
1140 - SECURITY FIX: Potential underflow/overflow bug in web
1142 - SECURITY FIX: Race condition in certificate creation.
1143 - SECURITY FIX: Bad URIs in browse packets could be used
1144 to exploint the web interface underflow/overflow bug.
1145 - SECURITY FIX: Some types of Denial of Service attacks
1146 were not handled properly, so once the attack was over
1147 the scheduler did not close the connections
1148 immediately on all platforms.
1149 - SECURITY FIXES: Added integer overflow/underflow
1150 checks for all image formats.
1151 - The pstops filter didn't reset the showpage operator
1152 back to its original at the end of a job; this
1153 prevented the concatenation of documents (used
1154 primarily for CUPS 1.2...)
1155 - The cupsGetPPD() function didn't always set the
1156 cupsLastError() value when an error occurred.
1157 - The IPP media, output-bin, and sides attributes took
1158 precedence over the corresponding PPD options, which
1159 caused inconsistent behavior under MacOS X with some
1161 - The cupsaddsmb utility specified the wrong number of
1162 arguments to the adddriver command when adding the
1163 Win9x PostScript drivers.
1164 - The web interface did not always report the correct
1166 - The scheduler did not clear the POSIX signal action
1167 structure when waiting for the child to send it a
1168 SIGUSR1 signal; this could cause the signal handler
1169 not to be called properly, preventing the parent
1170 process from returning.
1173 CHANGES IN CUPS V1.1.17
1175 - The "manual_copies" option did not work when the LPD
1176 backend had to retry a print job.
1177 - The image filters did not convert GIF images properly.
1178 - The RunAsUser option was incompatible with the new
1179 daemon-mode code in 1.1.16.
1180 - Fixed a problem with the Set-Job-Attributes and
1181 PostScript job ticket code in the scheduler - the
1182 "last" attribute pointer was never updated, which
1183 could cause the scheduler to crash when applying job
1185 - Fixed a problem in the scheduler that caused it to
1186 continue processing HTTP requests on a connection
1187 after it was shutdown.
1188 - The scheduler now allows accounts authenticated via
1189 PAM to not have a corresponding UNIX account, but
1190 group membership still requires the account name to be
1191 listed in the UNIX group file(s)...
1192 - The scheduler used a fixed-size (16k) buffer for
1193 encoding job options for filters; it now dynamically
1194 allocates and expands the buffer as needed depending
1195 on the options that are sent in a job.
1196 - The pdftops filter didn't support all of the MacOS
1197 characters for MacRoman encoded fonts.
1198 - The cupsEncodeOptions() and cupsParseOptions()
1199 functions now conform to the grammer defined by the
1200 current draft of the PAPI specification. The main
1201 difference is that option=yes and option=no are no
1202 longer treated as boolean options.
1203 - The IPP backend didn't honor the encryption settings
1204 in /etc/cups/client.conf.
1205 - Fixed a potential bug in the HTTP code which was
1206 caused by servers sending the status line and
1207 newline(s) in separate packets.
1208 - User-defined classification strings are now printed
1209 verbatim - previously the classification box would be
1211 - Re-added Spanish to the list of PPD languages that
1213 - CUPS API library user and temp file updates for
1215 - The image filters did not properly handle grayscale
1216 printing of Sun Raster images.
1217 - The scheduler never reset the NumJobs variable before
1218 loading the job list (previously this only happened on
1219 a full start, so the problem was never apparent...)
1220 - The HTTP and IPP read/write code didn't handle EINTR
1221 (interrupted system call) errors.
1222 - When under high load, the scheduler could abort due to
1223 the wrong errno value after a select() call. This was
1224 caused by the child signal handler.
1225 - Added new load tests to the test target to verify that
1226 cupsd can handle hundreds of simultaneous jobs without
1228 - The Solaris USB backend now supports the new device
1230 - The ppdOpen*() functions now reset the numeric locale
1231 settings while loading a PPD file.
1232 - Fixed the libtool build rules.
1233 - The manpage make rules didn't use $(MAKE) and
1234 $(MFLAGS) for the language subdirectories.
1235 - Now set the LC_TIME locale category to get the
1236 properly localized time string.
1237 - Fixed a problem in the scheduler that would cause the
1238 web interface problems when adding, modifying, or
1239 configuring a printer or class.
1240 - The backends now ignore SIGPIPE so that failed job
1241 filters will not stop a print queue.
1242 - The lpstat command did not allow for destination lists
1243 ("lpstat -v printer1,printer2")
1244 - Fixed parsing of long filter status messages in the
1246 - Added some startup performance enhancements to the
1247 scheduler so that the printer object information is
1248 regenerated fewer times and the MIME type database is
1249 not filled with lots of empty filters for raw/direct
1251 - The LPD backend now sends the job title as the print
1253 - Added support for variable sizes in the EPSON dot
1254 matrix printer drivers. This allows for pages as
1255 short as 1/2" (1 row of labels) and does not do an
1256 automatic form feed.
1257 - French translation updates.
1258 - The filters did not quote the page label string when
1259 embedding it in PostScript output.
1260 - The serial backend now enumerates serial ports under
1262 - The pdftops filter contained font rasterizer code that
1263 wasn't being used and that depended on X11. This code
1267 CHANGES IN CUPS V1.1.16
1269 - The cancel and lprm commands now both display an error
1270 message and return a non-zero exit status if an
1271 attempt is made to cancel a job on a non-existent
1273 - The lpoptions command incorrectly complained if a
1274 request to delete a non-existent printer was made.
1275 - If the client.conf file defines an alternate server
1276 name, the "configure printer" action in the web
1277 interface might not work.
1278 - The lpstat command now supports a "-W" option so that
1279 you can display completed jobs as well as
1280 not-completed (pending) jobs.
1281 - The lp and lpr commands did not return an error when
1282 one or more files in a set of files for printing could
1284 - The lp, lpadmin, and lpstat commands now consistently
1285 return with a non-zero exit status when an error
1287 - The scheduler would not accept print jobs sent to a
1288 stopped remote printer.
1289 - The texttops filter incorrectly converted the page
1290 numbers in the prettyprint header to double-byte
1291 characters when printing a non-Unicode text file. This
1292 caused an extra space to appear between each digit in
1294 - The scheduler did not use a case-insensitive
1295 comparison when adding filters for a printer.
1296 - Upgraded the pdftops filter to Xpdf 1.01.
1297 - The scheduler no longer passes the page-border and
1298 number-up-layout attributes to filters when printing
1300 - The LPD backend now uses a 30-second timeout when
1301 sending commands and control files, and a 30-second
1302 timeout when retrieving responses from an LPD server.
1303 If a timeout occurs, it retries indefinitely. This
1304 helps to make LPD printing over VPNs work more
1306 - The USB backend now supports device URIs based on the
1307 printer serial number and/or model number under Linux.
1308 This avoids the "wrong device filename" problem when
1309 using more than one USB printer.
1310 - Now just shutdown the receiving end of a client
1311 connection when sending an error that requires the
1312 server to disconnect from the client afterwards. This
1313 fixes a problem when doing remote administration with
1315 - The scheduler did not send a printer-state-message
1316 attribute if the string was empty; it now always sends
1317 this attribute. This caused the printer message to be
1318 displayed for other printers in the web interface.
1319 - The LPD backend now supports a "manual_copies" option,
1320 e.g.: "lpd://server/queue?manual_copies=no", in order
1321 to handle copies for raw jobs to printers that don't
1322 implement the LPD protocol properly...
1323 - The "mirror" option was not being handled by the
1324 PostScript or image filters.
1325 - Updated the cupsaddsmb command to support the new CUPS
1326 driver for Windows NT/2k/XP.
1327 - Filter status lines longer than 1023 characters could
1328 cause the scheduler to get into an infinite loop.
1329 - The scheduler didn't reset the job state to pending
1330 when modifying an active printer.
1331 - Now limit the maximum number of recursion steps when
1332 searching for a filter for a job, in case a user
1333 defines a circular filter rule.
1334 - The PostScript filter would embed an invalid
1335 requirements comment in some cases.
1336 - Added support for embedded job tickets in PostScript
1338 - The PostScript filter now detects EPS files and should
1339 better handle printing EPS files.
1340 - The cancel command now ignores a trailing destination
1341 name when cancelling a specific job ID (Solaris
1343 - The scheduler now rejects jobs with copies outside the
1344 range of 1 to MaxCopies, inclusive.
1345 - Added new MaxCopies directive to set the maximum
1346 number of copies that a user can request.
1347 - The scheduler didn't block signals while it processed
1348 others and when it forked processes.
1349 - The scheduler checked for new jobs to print when
1350 stopping a job. This caused jobs to restart before a
1352 - Updated the CUPS startup script to better support
1353 different timezones and to support the RedHat/Mandrake
1354 init script functions, if available.
1355 - The scheduler did not properly handle backslashes in
1356 banner files; it incorrectly assumed that "\c" should
1357 always be replaced by "c", instead of only looking for
1358 "\{" and replacing it by "{".
1359 - The texttops filter didn't handle prettyprint=no.
1360 - The text and HP-GL/2 filters didn't check for other
1361 common duplex option names like cupsMarkOptions() did.
1362 - "lpoptions -x printer" no longer clears the "default
1363 printer" status of the printer.
1364 - cupsTempFd() now stops trying to create a temporary
1365 file after 1000 tries, and aborts on any error other
1366 than EEXIST. This should prevent lp/lpr hangs due to
1367 a bad or missing temporary directory.
1368 - The lpadmin command did not send the right URI to the
1369 scheduler when setting options on classes. This
1370 caused a client-error-bad-request error.
1371 - The CUPS API convenience functions would attempt to
1372 connect to the remote server name in a
1373 "printer@server" printer name instead of dealing with
1374 the default (usually local) server. Aside from
1375 causing user confusion, the remote server name might
1376 not be resolved properly, causing further problems.
1377 - "lp -q" would cause the "lp" command to segfault, as
1378 the program would try to print the option letter that
1379 caused the error using the wrong index into the
1380 command-line; bugfix from Debian.
1381 - Fixed a minor inconsistancy in the encoding of boolean
1382 attributes from printer options in
1383 cupsEncodeOptions().
1384 - Added a FilterNice directive which sets the priority
1385 of job filter processes that are run by the scheduler.
1386 - Added Solaris x86 USB printer support.
1387 - The USB backend now reports both the ulpt and unlpt
1389 - The "lpstat -o" command would truncate the
1390 "printer-jobid" string if it was longer than 21
1392 - The PJL-based MIME type rules now look in the first
1393 1024 bytes instead of just the first 512 bytes to find
1395 - The image file types are now listed explicitly in the
1396 mime.convs file so that additional image file formats
1397 do not use the standard CUPS image filters by default.
1398 - Updated the Software Programmers Manual to include
1399 all of the CUPS API functions.
1400 - ppdOpen*() no longer sorts choices for an option.
1401 - The web interface now enforces constraints in PPD
1402 files when configuring a printer.
1403 - When stopping a printer, the scheduler didn't set the
1404 printer state before stopping the current job.
1405 - The cupsaddsmb utility now lists all data files for
1406 Win9x and WinMe clients when installing that Windows
1408 - Jobs submitted to a class now bounce immediately to
1409 the next available printer rather than waiting until
1410 that printer is available.
1411 - Filters and backends now also get the CLASS
1412 environment variable set when a job is printed to a
1413 printer class instead of a normal printer.
1414 - Added French translations of the web interface, CUPS
1415 Overview, Software Administrators Manual, and Software
1416 Users Manual contributed by Marian REYT-LLABRES.
1417 - Added several "hint" messages for common configuration
1418 problems that are stored in the error_log file.
1419 - httpSeparate() now unquotes %xx characters in the
1420 username:password field of a URI.
1421 - When starting the scheduler in daemon mode, the parent
1422 process now waits for the child to signal it is ready
1423 to accept connections.
1424 - Added -F option to cupsd to run cupsd in the
1425 foreground but detach from the controlling terminal
1426 and current directory.
1427 - The scheduler did not reload jobs when receiving a HUP
1428 signal; this would cause problems since the pointers
1429 into the file type database would no longer be valid
1431 - The scheduler did not save the network interface list
1432 update time, thus no caching of the network data was
1434 - Updated the SuSE PAM configuration file.
1435 - The LPD backend now supports a "reserve" option and no
1436 longer reserves a priviledged port by default.
1437 - The cupsaddsmb command now continues past printers
1438 that do not have a PPD file to export.
1439 - The lpstat command didn't treat printer names as
1441 - The lpstat command now reports the printer location
1442 attribute with "lpstat -l -p".
1443 - Fixed a bug in the vsnprintf() emulation function,
1444 which was used on old versions of HP-UX, IRIX, and
1446 - The number-up option was incorrectly being used when
1447 printing banner pages.
1448 - Added support for Greek and Slovak PPD files.
1449 - CUPS now supports printer names containing any
1450 printable character, e.g. "123-abc", "foo-bar", etc.
1451 - The null filter was not supported in mime.convs due to
1452 a bug in the filter validation code.
1453 - Changes in the default printer and printer attributes
1454 were not always reflected in the generated printcap
1456 - Implicit classes did not inherit the location or
1457 description from member printers.
1458 - The httpGetHostByName() function did not handle
1459 hostnames that started with a number.
1460 - Updated the filters to use the %cupsRotation comment
1461 instead of %%Orientation to auto-rotate pages, since
1462 the use of %%Orientation is inconsistent.
1463 - Added the RootCertDuration directive to control how
1464 often the root authentication certificate is updated.
1465 - Increased the size of the IPP write buffer to 32k to
1466 allow for larger attribute values and to provide more
1467 efficient output of large numbers of attributes.
1468 - The polling daemon now retries the initial connection
1469 to the remote server; this fixes a problem when the
1470 remote server is unavailable when the scheduler starts
1472 - The scheduler didn't validate Digest users against the
1473 system group(s), so Digest and BasicDigest
1474 authentication didn't work for administration
1476 - The scheduler now passes the SHLIB_PATH environment
1477 variable to child processes (HP-UX shared libraries)
1478 - The scheduler now maps accesses from the loopback
1479 interface to "localhost".
1480 - The cups-lpd mini-daemon sent a status code byte in
1481 response to queue state commands, but those commands
1482 only return textual data.
1485 CHANGES IN CUPS V1.1.15-1
1487 - The lpc and lprm sources didn't include the CUPS
1488 string function header, which is required on systems
1489 that don't have their own snprintf() function.
1490 - The French manpage Makefile tried to install the
1491 language subdirectories when it (obviously) didn't
1495 CHANGES IN CUPS V1.1.15
1497 - Updated the CUPS license agreement for the new MacOS
1499 - The printer-info attribute now defaults to the printer
1500 name if no value has been set.
1501 - ppdOpen() and friends now add an "Auto" InputSlot
1502 option if none is provided to automatically select the
1504 - Updated the ppdEmit() and ppdEmitFd() functions to
1505 (re)mark the correct PageSize or PageRegion option
1506 depending on the selected ManualFeed or InputSlot
1508 - ppdEmitFd() didn't handle custom page sizes.
1509 - Darwin uses <pam/pam_appl.h> instead of
1510 <security/pam_appl.h>.
1511 - The jobs.cgi web interface now handles all job
1512 operations, allowing the administrator to allow "job
1513 administrators" or operators to manage jobs (but not
1514 queues) on the server.
1515 - The cupsDoFileRequest() function now checks if the
1516 filename passed into the function is a directory, and
1517 returns the IPP_NOT_POSSIBLE error if so.
1518 - New SCSI printer backend.
1519 - Cleaned up handling of locales with trailing character
1521 - Fixed handling of invalid PPD attributes inside
1523 - Fixed a problem with SSL and the job, printer, and
1524 admin CGIs on ports other than 443.
1525 - The scheduler didn't handle AuthClass properly.
1526 - Added French translation of man pages.
1527 - Updated the text filter to support the const_cast,
1528 dynamic_cast, and static_cast keywords in ISO C++.
1529 - Now use strlcat() and strlcpy() (or emulation
1530 functions) for easier string/buffer protection.
1531 - The auto-generated printcap/printers.conf files now
1532 have a small comment header explaining where the file
1534 - The PostScript filter now supports 6, 9, and 16-up
1535 output, as well as new page-border and
1536 number-up-layout options.
1537 - The lpoptions command didn't set options properly when
1538 using the default printer.
1539 - Added ConfigFilePerm and LogFilePerm directives.
1540 - Increased maximum size of MIME types to IPP_MAX_NAME
1541 to allow for longer printer names.
1542 - No longer create remote printers when loading job
1544 - The printer-make-and-model attribute wasn't set when
1545 the PPD file didn't contain a NickName attribute.
1546 - Now handle PPD files with translation strings longer
1547 than 80 bytes - they are truncated if they go over...
1548 - The scheduler didn't handle signals until after it
1549 loaded the configuration files the first time; this
1550 caused problems on some installations that would
1551 restart the scheduler as the system booted into run
1553 - Now throttle broadcasts like we do for polling.
1554 - Fixed a bug in the reading of PPD files using CR's
1555 instead of CR LF's or LF's.
1556 - The scheduler would crash if cupsd.conf contained a
1557 BrowseProtocols line with no protocols listed.
1558 - The HTML job operation templates now link back to the
1559 destination printer or class.
1560 - The serial backend now detects USB serial devices.
1561 - The LPD mini-daemon (cups-lpd) now passes the
1562 job-originating-host-name attribute to the scheduler
1564 - Updated the IPP backend to reconnect after downgrading
1565 from IPP/1.1 to 1.0, and when sending requests to HP
1566 JetDirect interfaces that don't support HTTP
1567 Keep-Alive like they should.
1568 - Now pass NLSPATH and DYLD_LIBRARY_PATH environment
1569 variables, if defined, to CGI and job processes.
1570 - Removed the pstoraster filter (based on GNU
1571 Ghostscript 5.50) and now provide the raster "driver"
1572 and patch file necessary to use the current GNU
1573 Ghostscript 7.05 release.
1574 - Removed unnecessary fonts and updated the Courier and
1575 Symbol fonts to the latest versions to better support
1577 - The text filter now always embeds the Courier and
1578 Symbol fonts to ensure that they contain the full set
1580 - The lp and lpr commands now only override the SIGINT
1581 handler if it is not being ignored (patch from Robert
1582 Ambrose for some interactive software that catches
1583 SIGINT and will gracefully cancel the print...)
1584 - The PostScript image filter (imagetops) now supports
1585 printing CMYK images using the CMYK colorspace.
1586 - The image filters now support CMYK JPEG files, and
1587 correctly handles the inverted files from Photoshop
1588 (which seems to save RGBW data, not CMYK...)
1589 - Added a "check" target to the top-level makefile to
1590 conform with GNU standards (same as "test").
1591 - The IPP code didn't always map the POSIX locale "C" to
1592 the proper IPP language code.
1593 - The cupsaddsmb program was updated to use the
1594 setdriver command instead of addprinter.
1595 - Banner pages were not handled properly for implicit
1597 - When tunneling to a remote system using SSH, the
1598 printer URIs for local printers on the remote system
1599 did not reflect the correct port number.
1600 - The Allow, Deny, BrowseAllow, BrowseDeny, and
1601 BrowseAddress directives now support the network
1602 interface names "@LOCAL" and "@IF(name)" for access
1603 control and browsing based on the current interface
1604 addresses instead of fixed names or IP addresses.
1605 - The texttops filter did not properly recognize the
1606 "nowrap" (wrap=false) option.
1607 - The InstallableOptions group name in a PPD file is now
1608 translated separately (CUPS_MSG_OPTIONS_INSTALLED) so
1609 that UIs can accurately detect the presence of this
1611 - The scheduler no longer keeps job history data for
1612 remote printers on the client (just on the server.)
1613 - The parallel and USB backends now retry if the backend
1614 detects that the printer is not connected to the
1615 system (rather than stopping the queue...)
1616 - The network backends now retry if the backend detects
1617 that the printer is not connected to the network or is
1618 unreachable (rather than stopping the queue...)
1619 - The cupsGetDests() function no longer lists options
1620 and instances for printers that no longer exist.
1621 - The scheduler now converts the document language to
1622 the correct LANG string.
1623 - The cupsaddsmb program now supports alternative CUPS
1624 and SAMBA server names.
1625 - The PostScript filter now supports the Orientation
1626 comment and rotates the page as needed automatically.
1627 - Revamped the makefiles slightly to use automatically
1628 generated dependencies.
1629 - Build fixes for OS X.
1630 - The TIFF reading code depended on the newest version
1631 of libtiff; now conditionally compile that portion of
1633 - The PPD code now decodes all JCL options in the
1634 JCLSetup group, not just those options that start with
1636 - The backends now read print data using the read()
1637 system call to ensure that the current page is printed
1638 while the next page is being processed.
1639 - The pdftops filter did not support shading type 3
1640 (radial fill) for the "sh" operator.
1641 - The cups-polld program now throttles the local
1642 broadcasts of polled printers and classes so that the
1643 local system is not overwhelmed with hundreds of
1644 printers and classes all at once.
1645 - Updated the serial backend to support 230,400 baud for
1647 - The cupsGetJobs() function wouldn't report completed
1648 jobs that did not have a document-format attribute
1650 - The cupsEncodeOptions() function now maintains a table
1651 of known boolean and numeric options, and encodes all
1652 other options as strings.
1653 - Now add a newline before the end-of-page code in the
1654 PostScript filter; this fixes a problem with files
1655 that don't end with a newline.
1656 - The image filters looked for the "orientation" option
1657 instead of the correctly named "orientation-requested"
1659 - The cupsEncodeOptions() function now handles mixed
1660 integers and ranges.
1661 - New translation guide for developers to provide native
1662 language support for CUPS.
1665 CHANGES IN CUPS V1.1.14
1667 - The ippRead() function did not verify that the
1668 attribute name length or string with language value
1669 was not larger than the read buffer.
1670 - The scheduler set the signal handlers before loading
1671 the configuration files the first time; this prevented
1672 the RunAsUser directive from blocking server reloads.
1673 - Added Swedish message catalog.
1674 - The parallel backend now recognizes the /dev/printers
1675 device directory under Linux 2.4.x.
1677 - The cupsaddsmb utility sent the server name after the
1678 user information when executing the rpcclient program.
1679 This caused problems with some versions of SAMBA
1681 - The IPP backend did not pass the requesting user name
1682 when checking on the print job status. This prevented
1683 it from waiting for the job to complete when
1684 communicating with some IPP implementations that
1688 CHANGES IN CUPS V1.1.13
1690 - The lpstat command did not report jobs submitted to
1691 regular printer classes.
1692 - The texttops filter didn't use sufficient precision
1693 when positioning text with some values of cpi and lpi.
1694 This could cause the alignment of text to stray.
1695 - cupsGetDests() didn't merge the options from the
1696 /etc/cups/lpoptions file with ~/.lpoptions - options
1697 in ~/.lpoptions overrode them completely.
1698 - Added support for KOI8-R and KOI8-U character sets,
1699 and added several Russian message catalogs.
1700 - The scheduler put the wrong timezone offset in the log
1701 files (e.g. +0500 instead of -0500 for EST...)
1702 - The scheduler did not ignore trailing whitespace in
1704 - The scheduler now forces all processes to exit (kill
1705 -9) when it is stopped. This prevents parallel and
1706 USB devices from running in the background after cupsd
1708 - The cupsParseOptions() function didn't skip trailing
1709 whitespace after quoted values.
1710 - More changes to support CUPS on OS/2.
1711 - Added Simplified Chinese message catalog.
1712 - Added PAM support for IRIX.
1713 - The cupsGetPPD() function didn't remove the @server
1714 portion of the printer name, and since it would
1715 connect immediately to the remote server instead of
1716 the local server, the printer would not be found.
1717 - Classification and page labels were not rotated to
1718 match the page orientation.
1719 - Now set the TCP "no delay" option on network
1720 connections to improve performance/response time.
1721 - Improved the IRIX printing tools support with patches
1722 from Andrea Suatoni.
1723 - Added a new PrintcapGUI directive to specify the GUI
1724 option panel program to use for the IRIX printing
1726 - The cupsGetDests() function did not check to see if a
1727 user-defined default printer (set via lpoptions) still
1729 - The pstops filter no longer assumes that the default
1730 dictionary is writable when doing N-up processing.
1731 - The pstops filter now supports printing N-up with the
1733 - The imagetoraster filter now supports direct printing
1734 of CMYK image data without conversion/correction.
1735 - The IPP backend now reports printer state/error
1736 conditions when possible (toner low, media empty,
1738 - The lpstat command now supports the (undocumented)
1739 IRIX -l option ("-lprintername") for a compact job
1740 listing for a printer.
1741 - The lpstat command now includes printer date/time
1742 information in the output (always Jan 01 00:00) to
1743 make third-party tools happy.
1744 - The text filter now supports non-integer cpi and lpi
1746 - The Margins field in the CUPS raster header was not
1747 initialized by the pstoraster filter.
1748 - Added --with-optim="flags" option to configure script.
1749 - Updated the Italian message translations.
1750 - Updated the cups.list file to install the correct
1752 - The pstoraster filter accessed the third element of a
1754 - The scheduler did not setup a status pipe for polling
1755 processes, so error messages went to whatever file
1756 descriptor 2 was pointing to when they were started.
1757 - The httpMD5Final() function didn't put a colon between
1758 the password and nonce strings.
1759 - The pstops filter did not default to Binary data for
1761 - The pstops filter did not stop processing when a line
1762 containing a CTRL-D is seen.
1763 - The scheduler no longer replaces the JobSheets values
1764 from the printers.conf and classes.conf files with the
1765 classification level, if set. This way the original
1766 banner settings are preserved when classification
1767 levels are changed or turned off.
1768 - The serial backend didn't drain the output queue, nor
1769 did it restore the original settings.
1770 - Updated the default system group under MacOS X.
1771 - If no SystemGroup was defined in cupsd.conf, the
1772 system default group was not used.
1773 - The cups-lpd mini-daemon now supports LPD clients that
1774 send multiple control files.
1775 - httpConnectEncrypt() now always uses encryption for
1776 connections on port 443, since port 443 is reserved
1777 for the "https" scheme.
1778 - Group authentication via certificates did not work
1779 from the web interface for accounts other than
1781 - The serial port backend did not clear the OPOST
1782 option, which could cause problems with some printers.
1783 - The cups-lpd mini-daemon didn't lookup the client IP
1785 - The parallel backend now identifies the polled and
1786 interrupt-driven devices under *BSD.
1787 - The scheduler allowed the "always" encryption mode
1788 inside a Location, which is not valid.
1789 - The CUPS startup script now checks for the timezone
1790 information under Linux.
1791 - Now also map the sides attribute to the JCLDuplex
1792 option (if present) in PPD files.
1793 - Updated pdftops to Xpdf 0.93a.
1794 - Added support for MD5 passwords under Slackware.
1795 - Added new AuthType BasicDigest that does Basic
1796 authentication using the MD5 password file managed by
1797 the lppasswd command.
1798 - The banner page attribute substitution code now
1799 retains {name} sequences in banner files when the
1800 named attribute is undefined. Use {?name} to
1801 conditionally substitute an IPP attribute.
1802 - The scheduler now ensures that the ServerRoot
1803 directory and configuration files are owned by and
1804 writable by the User and Group in cupsd.conf.
1805 - The USB backend now lists all USB printer devices
1806 regardless of whether a printer is connected or not.
1807 This allows new USB printers to be connected without
1809 - Added some more minor performance tweeks to the IPP
1810 protocol code to reduce copying and array indexing.
1811 - The cupsaddsmb utility now uses the -c option with
1812 smbclient and rpcclient to avoid the read length limit
1813 for commands on the standard input.
1814 - Added an include file to the CRD handling code in
1815 pstoraster so that it would compile properly on 64-bit
1816 pointer platforms...
1819 CHANGES IN CUPS V1.1.12
1821 - Added "Polish" to the list of known languages for PPD
1823 - Added missing directory definition to cups-config.
1824 - The CUPS-Move-Job operation did not set the
1825 destination type for the new destination.
1826 - The CUPS-Add-Printer operation did not support the
1827 allow=all or deny=none values to clear the per-user
1829 - The SetPrinterAttrs() function did not handle invalid
1830 PPD files that were missing the required NickName
1831 attribute. It now looks for NickName, ModelName, and
1832 then substitutes the string "Bad PPD File" for the
1833 printer-make-and-model attribute.
1836 CHANGES IN CUPS V1.1.11
1838 - Added support for embedded TrueType fonts in PDF
1840 - Added support for PostScript functions in PDF
1842 - Added new "cupsaddsmb" utility for exporting
1843 CUPS printer drivers to SAMBA/Windows clients.
1844 - Added preliminary support for Darwin/MacOS X.
1845 - The CUPS-Add-Printer operation no longer allows
1846 arbitrary scheme names in device URIs to be used - it
1847 now restricts the available schemes to those found in
1848 the device list (lpinfo -m).
1849 - The ippRead() and ipp_read_file() functions could not
1850 handle more than IPP_MAX_VALUES (100) values in a
1851 1setOf attribute. These functions have been updated
1852 to dynamically allocate more memory as needed, and the
1853 IPP_MAX_VALUES constant now represents the allocation
1854 increment. [this caused some versions of the
1855 GIMP-print drivers to fail since the number of media
1856 options exceeded 100...]
1857 - The scheduler could crash when BrowseShortNames
1859 - The scheduler did not prevent MaxClients from being
1860 set to 0, which could cause the scheduler to go in an
1861 infinite loop when accepting a request.
1862 - Made some performance optimizations in the ippRead()
1863 functions to make IPP request/response processing
1865 - The accept/reject/enable/disable command did not
1866 support properly support the "-h" or default
1868 - The scheduler did not save the quota configuration
1869 when the job-quota-period attribute was set to 0.
1870 - The LPDEST and PRINTER environment variables did not
1871 support printer instances.
1872 - The text filter now handles more types of boldface and
1873 underline formatting.
1874 - The cupsTempFd() function did not fail if the
1875 temporary directory did not exist; this would cause it
1876 to loop indefinitely instead of returning an error
1878 - Stopping (disabling) a printer class did not stop jobs
1879 from printing to printers in that class.
1880 - The cupsGetDests() function was sending the
1881 requested-attributes attribute as a name instead of a
1882 keyword; this caused a serious performance problem on
1883 slower systems since more information had to be
1884 transferred from server to client.
1885 - The web interfaces did not always quote < and & in
1886 things like the job title. This had the potential for
1887 browser-based security violations (on the browser's
1888 machine); bug report from SuSE.
1889 - The scheduler now treats unauthenticated usernames as
1890 case-insensitive when doing quota and allow/deny
1892 - The lp command sent the "request ID is ..." message
1893 to stderr instead of stdout...
1894 - The PostScript filter (pstops) now handles EPS files,
1895 adding a showpage command to the files as needed.
1896 - The configure script checked for the <stdlib.h> header
1897 file before the JPEG libraries; since the JPEG headers
1898 can define HAVE_STDLIB_H, the configure check would
1899 cause the JPEG check to fail on some systems.
1900 - The scheduler now supports localized banner files,
1901 using the subdirectory approach, e.g. the "es"
1902 subdirectory under /usr/share/cups/banners is used for
1903 the Spanish banner files.
1904 - Updated the scheduler so it knows the correct
1905 language abbreviation to use for all supported
1906 PPD LanguageVersion values. The new code also
1907 supports country codes as well, so "English-GB"
1908 maps to the "en_GB" locale.
1909 - The cups-lpd mini-daemon did not support
1910 anonymous printing (no username specified).
1911 While the username is REQUIRED by RFC-1179,
1912 MacOS clients do not send the REQUIRED username
1913 information when printing via LPD.
1914 - Added many warning and informational messages
1915 to cups-lpd where they were missing.
1916 - Added Czech message file contributed by SuSE.
1917 - The cups-lpd mini-daemon now returns a non-zero
1918 status if an invalid destination or job ID is
1920 - The scheduler did not honor the KeepAlive setting in
1922 - Increased the size of the file read/write buffers to
1924 - *BSD static library creation fixes.
1925 - Use mkstemps() instead of tmpnam() in pdftops whenever
1927 - Added httpGetHostByName() function as a wrapper around
1928 gethostbyname() - some implementations of this
1929 function do not support IP addresses (e.g. MacOS X.)
1930 - Added casts to all printf's of file lengths, since
1931 there is currently no standard way of formatting long
1933 - The client filename field was not cleared in all
1934 instances, resulting in old form data being submitted
1936 - The httpConnect*() functions now try all available
1937 addresses for a host when connecting for the first
1939 - The pstoraster filter would "lose" all drawing
1940 commands when the PageSize was set but the printer
1941 bitmap was not reallocated. This was most noticeable
1942 with the output from StarOffice 6 beta and would
1943 result in a blank page being output...
1944 - The IPP backend was sending a PAGE comment even when
1945 printing the output from a filter (it should only send
1946 page comments when printing files directly...)
1947 - The pdftops filter didn't properly map glyph names of
1948 embedded Asian TrueType fonts.
1949 - Changed the CUPS startup script to look for a program
1950 named "cupsd", not just any program with "cupsd" in
1951 the name (this caused the apcupsd UPS monitoring
1952 daemon to be stopped/restarted...)
1953 - The CUPS-Move-Job operation did not change the
1954 internal destination name for held jobs, so moved (but
1955 held) jobs would still show up as queued on the
1956 original destination.
1957 - The cups-polld program didn't send the
1958 requested-attributes attribute in the
1959 CUPS-Get-Printers and CUPS-Get-Classes requests, which
1960 made it use more CPU and bandwidth than required.
1961 - The scheduler and CUPS API incorrectly added a
1962 job-sheets-default attribute for remote printers. This
1963 caused banner pages to be omitted from client system
1967 CHANGES IN CUPS V1.1.10-1
1969 - Minor fixes to the filter, systemv, and template
1970 makefiles to install files properly.
1973 CHANGES IN CUPS V1.1.10
1975 - Added a driver for DYMO label printers.
1976 - Added new ClassifyOverride directive to allow users
1977 to override the classification of individual jobs.
1978 - Added new BrowseProtocols directive to control which
1979 browse protocols are used (currently CUPS and SLP).
1980 - Added SLPv2 support (thanks to Matt Peterson for
1981 contributing the initial implementation for CUPS.)
1982 - Adding a raw printer on a remote CUPS server now
1983 correctly redirects PPD file requests to the remote
1985 - The serial backend now limits writes to 1/10th
1986 second worth of data to avoid buffer overflows
1987 with some types of flow control.
1988 - The scheduler did not properly process PUT requests,
1989 so configuration files could not be uploaded to the
1991 - The scheduler did not strip trailing whitespace on
1992 lines in the configuration files.
1993 - The httpWrite() function did not transition the PUT
1994 request to the HTTP_STATUS state to get the status
1996 - The scheduler did not properly handle trailing null
1997 ("-") filters when testing a driver that sent data
1998 to the file: pseudo-backend.
1999 - The IPP backend now only sends a document-format of
2000 "application/vnd.cups-raw" when printing to another
2001 CUPS server using a local printer driver or interface
2002 script. Previously the job's document format was
2003 used, which was incorrect.
2004 - The lpadmin command didn't use the ppd-name attribute
2005 with the -m option; this prevented the use of the
2006 "raw" model from the command-line.
2007 - The pstoraster filter output draft (1-bit) 6-color
2008 output in the wrong order; this resulted in yellow
2009 being printed instead of black on Stylus Photo
2011 - The pdftops filter did not have the Japanese and
2012 Chinese text support compiled into it.
2013 - The IPP and AppSocket backends did not clear the
2014 "waiting for print job to complete" status message,
2015 which caused some confusion... :)
2016 - The serial backend now opens the port in "no delay"
2017 mode to avoid DCD detection problems with some OS's.
2020 CHANGES IN CUPS V1.1.9-1
2022 - The configure script did not substitute the
2023 correct user and group names.
2024 - The configure script did not use the full path
2025 to the install-sh script when it was used.
2026 - The pstoraster filter did not correctly support
2027 DuplexTumble mode for printers that used flip
2029 - The cups.list.in file was missing from the
2031 - The New DeskJet series driver did not use the
2032 correct OrderDependency for the Duplex option.
2033 - Use read() instead of fread() to read piped
2034 print files in lpr/lp. This avoids a bug in the
2035 HP-UX 10.20 fread() function.
2036 - Updated the pstoraster filter to use the MIPS_FIXADE
2037 system call under IRIX to fix bus error problems on
2038 R12000 processors (Ghostscript is not 64-bit clean...)
2039 - Some Xerox PPD files (most notably the Phaser 790)
2040 have illegal whitespace in the option keyword in the
2041 OpenUI line. This caused the PageRegion option to not
2042 be recognized properly for the Phaser 790.
2045 CHANGES IN CUPS V1.1.9
2047 - Revamped the configure script to use a modular
2048 approach for the various tests.
2049 - Added --with-openssl-* options to properly reference
2050 the OpenSSL libraries in DSOs.
2051 - Added --with-cups-user and --with-cups-group
2052 options to specify the default user and group for
2054 - Added AIX shared library support.
2055 - Added AIX device discovery for the serial and
2057 - Now use install program or script to install
2058 directories, files, and symlinks.
2059 - Updated pstops filter to use strict handling of EPS
2060 files embedded in a PostScript document. The %%EOF
2061 handling in 1.1.8 caused some dvips files not to
2063 - Fixed yet another memory allocation bug in pstoraster
2064 that would cause it to crash. This fix also ensures
2065 that all memory allocations are done on (at least) a
2067 - Fixed Digest authentication - httpGetSubField() didn't
2068 skip the Digest keyword.
2069 - The scheduler did not properly handle Digest
2070 authentication with the new multiple-group support.
2071 - The scheduler did not allow usernames that were
2072 not in the UNIX password file to be used for Digest
2073 authentication from passwd.md5.
2074 - The scheduler could not scan PPD files that only used
2075 a carriage return (i.e. MacOS PPD files); the new code
2076 is also about 40% faster, so servers with thousands of
2077 PPD files should start much faster now.
2078 - The scheduler now stores the PPD file size and
2079 modification times in the ppds.dat file, so it can now
2080 incrementally update the PPD database from the model
2081 directory, resulting in significantly faster startup
2083 - The lpinfo command did not return a non-zero status
2084 code if an error occurred.
2085 - Fixed a bug in the scheduler's UpdateJob() function.
2086 Basically, all jobs shared the same status buffer, and
2087 the "buffer start" pointer could point to 1 byte
2088 before the beginning of the buffer. The new
2089 implementation uses a separate buffer for each job and
2090 eliminates the buffer start bug.
2091 - The IPP backend would send N copies of a document if
2092 the receiving device didn't support the copies
2093 attribute, even if the upstream driver already added
2094 the necessary commands to generate the copies. This
2095 was most noticeable with HP printers where N * N
2096 copies would come out instead of N.
2097 - The PostScript filter (pstops) did not properly handle
2098 duplex printing on inkjet printers that provide this
2099 option. Copies would be put on the front and back
2100 sides of the duplexed page, and the filter did not
2101 output an even number of pages.
2102 - The backends always caught SIGTERM after they
2103 connected to the printer. This prevented raw jobs
2104 from being cancelled early.
2105 - The cupsSetDests() function now removes any printers,
2106 instances, and options that are not defined by the
2107 user or server. This should prevent old system-wide
2108 options from being used in individual user accounts.
2109 - Updated the EPSON printer driver and added PPDs for
2110 the newer EPSON Stylus printers that only support the
2111 "ESC i" graphics command.
2112 - The lpadmin command didn't allow you to add remote
2113 printers to a local class.
2114 - The lpadmin command didn't allow you to set the
2115 options (quotas, etc.) for a class.
2116 - The scheduler did not load or save the
2117 job-sheets-default attribute for classes.
2118 - The scheduler did not automatically recreate remote
2119 printers that were part of a class.
2120 - It was possible for a printer class to list the same
2121 printer more than once.
2122 - The scheduler now makes a backup copy of classes.conf
2123 and printers.conf before writing the new file.
2124 - The lppasswd program incorrectly asked for a new
2125 password when deleting an existing MD5 password
2127 - The scheduler did not match "/printers/name.ppd"
2128 against a location of "/printers/name".
2129 - The client code did not always handle HTTP encryption
2131 - The client code now caches the last Digest password so
2132 it can retry using a new resource path or nonce value,
2133 which are included in the MD5 sum sent to the server.
2134 This should eliminate unnecessary password prompts
2135 when using Digest authentication.
2136 - The lppasswd command didn't have a man page.
2137 - Updated the PJL detection rules to allow the universal
2138 escape to occur anywhere in the first 128 bytes of the
2140 - The cups-polld program would poll servers continuously
2141 with no delay if there was an error contacting the
2143 - The IPP backend would send an empty job-name or
2144 requesting-user-name attribute if the corresponding
2145 job attribute was an empty string. While this is
2146 allowed by the IPP specification, some HP JetDirect
2147 implementations return a client-error-bad-request
2148 error if an empty name attribute value is received.
2149 The new code only sends these attributes if they are
2150 not the empty string.
2151 - At least some versions of the HP JetDirect firmware
2152 do not correctly implement IPP. Added additional
2153 checks to the IPP backend to eliminate extra,
2154 unsupported attributes which should normally be
2155 ignored by a compliant IPP device.
2156 - The scheduler did not copy the complete list of
2157 supported file types into the
2158 document-format-supported attribute. This caused
2159 clients to not send the local file type (such as
2160 application/vnd.cups-raw for raw print files) and the
2161 corresponding bad output in some cases.
2162 - The scheduler did not fully copy attributes from a
2163 set-job-attributes request - string attributes were
2164 only referenced, which could cause cupsd to crash
2165 or behave irratically.
2166 - The lp command didn't send the right value for the
2167 job-hold-until attribute when "-H resume" was
2169 - The IPP backend now returns as soon as a job is
2170 completed or reported as "pending-held".
2171 - Added new ImplicitAnyClasses and HideImplicitMembers
2172 directives to the cupsd.conf file to make implicit
2173 classes more usable/transparent to the user.
2174 - Clients can now (with the appropriate authentication)
2175 retrieve and update the server configuration files
2176 using HTTP GET and PUT requests.
2177 - The web interface didn't allow you to modify the
2178 location or description of the printer.
2179 - The pdftops filter now uses its own temporary file
2180 function to work with PDF files using LZW compression
2181 (which use the uncompress program or gunzip)
2182 - The SystemGroup directive now supports specification of
2184 - Added new Include directive to cupsd.conf, a la
2186 - Added new pseudo-driver/PPD called "raw" that can be
2187 used to create/convert a raw queue. This also allows
2188 raw queues to be created in the web interface.
2189 - The pdftops filter didn't handle image objects that
2190 used JPEG and Flate compression together.
2191 - The pstops filter counted pages wrong when using the
2192 N-up and even/odd printing options. This prevented
2193 the page-ranges option from working properly.
2194 - Added another fix to pstoraster for a bus error
2195 condition caused by a lack of parenthesis in the
2197 - Added new "natural-scaling" option which scales the
2198 natural size of the image (percent of natural image
2199 size instead of percent of page size.)
2200 - The lppasswd program is now setuid to the CUPS user
2202 - The PPD functions did not allow for PPD files that
2203 defined the page sizes and margins before the page
2205 - The mime.types file now checks for the PJL "LANGUAGE =
2206 Postscript" command for PostScript files.
2207 - The scheduler did not truncate file: output files.
2208 - The PPD file reading code did not handle options with
2209 raw quotes (") in the human-readable names.
2210 - The pdftops filter now remaps the space character when
2211 (bad) PDF files contain a .notdef glyph for the space
2215 CHANGES IN CUPS V1.1.8
2217 - Updated spec file to generate separate cups-pstoraster
2218 package for pstoraster.
2219 - The spec file wasn't setting LOGDIR in the install.
2220 - The scheduler might restart a stopped printer after
2221 stopping a print job. Thanks to Florent
2222 Guiliani for finding this bug!
2223 - The init script showed run level 0 for the Red Hat
2224 chkconfig program. This is incorrect because Red Hat
2225 doesn't use run level 0 for shutdown scripts.
2226 - The IPP backend did not handle the
2227 client-error-not-found error when checking the status
2228 of the job that was sent. This caused remote queues
2229 to stop on client machines when the server had job
2231 - Added httpConnectEncrypt() function to avoid
2232 performance penalty for setting up encrypted
2233 connections initially.
2234 - Use httpConnectEncrypt() in all client apps and in the
2235 CUPS API to ensure consistent usage of encryption
2237 - Jobs weren't queued to remote classes (fix from
2239 - AIX changes from Richard Begg.
2240 - Fixed the pstops fix for GNOME output - no longer use
2241 the page numbers in the %%Page: comment since GNOME
2242 puts a filename instead (!?@!#?!). There is still an
2243 issue with N-up printing since GNOME defines its fonts
2244 in the first page instead of the document setup section
2245 (pages must be independent according to the DSC spec)
2246 People with GNOME printing problems should consult bug
2248 - The imagetops filter produced PAGE: messages when
2249 generating PostScript for a non-PostScript printer
2250 (only affects page-label and Classification
2252 - The updated pdftops filter was looking for an options
2253 file called xpdf.conf instead of pdftops.conf.
2256 CHANGES IN CUPS V1.1.7
2258 - Configuration script changes, including new
2259 "--with-docdir=/dir" option to relocate CUPS
2260 documentation and web content according to your
2261 favorite version of the FHS.
2262 - Documentation updates for encryption, SLP, etc.
2263 - New Software Test Plan and automated test script to
2264 test CUPS prior to installation.
2265 - All scheduler configuration files are now case
2266 insensitive to match Apache.
2267 - Added support for Apache ListenBackLog, Require,
2268 Satisfy, <Limit>, <LimitExcept>, and LimitRequestSize
2270 - Added support for all Apache log levels...
2271 - Added support for "double" HostNameLookups.
2272 - Added new "RunAsUser" directive to support non-root
2273 configurations on the standard (priviledged) ports.
2274 - Added support for non-root invocation of the lpd
2275 backend (does no reserve a priviledged port, which
2276 might not work with some LPD servers...)
2277 - Added new PrintcapFormat directive to control the
2278 output format of the printcap file (BSD or Solaris
2279 formats are supported at present.)
2280 - The CUPS directory service routines now handle
2281 ECONNREFUSED errors gracefully rather than shutting
2283 - ippErrorString() now returns the recommended error
2284 messages from the IPP/1.1 Model and Semantics
2286 - Fixed a minor IPP compliance issue with responses
2287 to requests without the attributes-charset or
2288 attributes-natural-language attributes.
2289 - Sun fix: need httpFlush() call for chunked IPP
2290 requests in cupsDoFileRequest().
2291 - httpConnect() now looks up "localhost" by name and
2292 by address (127.0.0.1) for users the go to the
2293 trouble of removing the required localhost entry
2294 in /etc/hosts or on their DNS server...
2295 - Added support for Linux 2.4.x devfs parallel port
2296 filenames (/dev/parallel/N).
2297 - cupsDo[File]Request() and cupsGetPPD() no longer
2298 block trying to reconnect to a crashed or inaccessable
2300 - Added new ppdEmitJCL() function to better handle
2301 PJL commands from PPD files.
2302 - A bug in UpdateJob() would cause the scheduler to
2303 consume 100% CPU until another request was submitted.
2304 - The cancel command did not support the "-" option to
2305 cancel all jobs on all printers.
2306 - The cancel and lprm commands did not support cancelling
2307 the next/current job in the queue.
2308 - The pdftops and pstoraster filters were using unsafe
2309 temporary file functions; while this is not a problem
2310 in normal configurations (the CUPS temporary directory
2311 is restricted), they now use the cupsTempFd() function.
2312 - The mime.types file was missing the recognition rule
2313 for Sun Raster images.
2314 - The admin CGI was passing a printer make string to
2315 ippSetCGIVars() that was being replaced in that
2317 - "lpoptions -l" would resave the options...
2318 - The EPSON drivers now send the "end packet mode"
2319 command when printing to USB devices.
2320 - The scheduler initialized certificates before loading
2321 the cupsd.conf file.
2322 - The scheduler used /dev/random to collect random data,
2323 which could block if insufficient entropy information
2324 had been collected by the kernel. Now use
2326 - Fixed a bug in the whitespace skipping code in
2328 - The LPD backend now supports a new "order" option:
2329 "lpd://server/queue?order=control,data" (default) and
2330 "lpd://server/queue?order=data,control".
2331 - The scheduler enforced a 30 second timeout on all
2332 clients regardless of the Timeout directive and if a
2333 CGI was currently running.
2334 - cupsParseOptions() now sets boolean options to
2335 option=true or option=false.
2336 - The "percent complete" calculations in the LPD backend
2337 could overflow on large files, causing the percentage
2338 to wrap to 0 every 40MB or so.
2339 - Fixed a memory reallocation bug in pstoraster that
2340 could cause it to crash.
2341 - The LPD backend now sanitizes the job title to avoid
2342 potential problems on remote LPD servers.
2343 - The lp command did not send the requesting-user-name
2344 attribute when altering a job.
2345 - The pstops filter did not handle PostScript files with
2346 lines longer than 8191 bytes.
2347 - The scheduler no longer uses inet_addr() to convert IP
2348 addresses in dot format (mmm.nnn.ooo.ppp) to the
2349 32-bit format, since it will not work for IPv6
2351 - New "Classification" directive to force labeling of
2352 the current classification on each page.
2353 - New "page-label" attribute to add per-page labels
2354 ("For Official Use Only", "Draft", etc.)
2355 - The scheduler now sets the HTTPS environment variable
2356 for CGI programs when a client connects using
2358 - Fixed a recursion bug in the scheduler that could
2359 cause cupsd to crash when a printer was removed.
2360 - The LPDEST and PRINTER environment variables didn't
2362 - Dropped the "file" backend from the device list that
2363 is reported, since it is only available for *testing*
2364 and should never be used in a production environment.
2365 The file: device can still be used, but it won't show
2366 up in the list of devices from lpinfo or the web
2368 - Added support for /dev/lpa# parallel ports under *BSD.
2369 - Added META variables to the CGI header template to
2370 prevent caching of the results.
2371 - Fixed an unaligned memory buffer for the pstoraster
2372 clist states; this caused bus errors for some
2373 combinations of printers, drivers, and options.
2374 - Re-added black reduction for colorful colors; this
2375 helps to prevent dark colors from getting desaturated.
2376 (only used when converting RGB to CMYK)
2377 - Added two new directives - MaxJobsPerPrinter and
2378 MaxJobsPerUser - to allow an administrator to set
2379 the maximum number of pending jobs in a queue or
2380 submitted by a user.
2381 - The scheduler no longer stops a printer if it can't
2382 create the status pipe or run the filters or backend.
2383 This will allow heavily loaded servers to service
2384 clients or start print jobs as the load allows.
2385 - Fixed a bug in the Set-Job-Attributes code that could
2386 crash the scheduler (patch from Martin Zielinski)
2387 - cupsSetDests() did not quote option values with
2389 - Added support for the Enable-Printer and
2390 Disable-Printer extension operations (same as
2391 CUPS-Accept-Jobs and CUPS-Reject-Jobs.)
2392 - The AppSocket and IPP backends now wait for the print
2393 job to be finished before exiting; this should prevent
2394 the loss of print jobs with older JetDirect firmware
2395 and make consecutive print jobs print faster.
2396 - The BMP loading code did not handle resolution values
2397 of 0. This is a problem with BMP image files produced
2399 - The HTTP Upgrade code (upgrade to TLS encryption)
2400 bypassed the authentication checks.
2401 - The HTTP Upgrade code did not send a 426 status code
2402 to the client and end the current request. This caused
2403 a race condition between the client and server for the
2405 - Fixed a bug in the EOF and Trailer detection code in
2407 - The imagetoraster filter did not add the margins to
2408 the custom page size in the raster header.
2409 - The imagetops filter did not adjust the custom page
2410 size to the size of the printed image.
2411 - The imagetops filter did not include DSC comments
2412 which are required by some printers.
2413 - The imagetops filter did not insert newlines in
2414 Base85 encoded output, causing files to contain
2415 lines longer than 255 characters (violation of the
2417 - Added support for the DeskJet 900 series duplexer
2418 and CRET color modes in the HP driver.
2419 - Added support for PPD-defined margins in the HP
2421 - Fixed the debugging output from pstoraster - the
2422 font list was not terminated by a newline.
2423 - Some versions of the HP-UX pam_unix authentication
2424 module apparently do not pass the appdata_ptr argument
2425 to the conversation function, preventing the scheduler
2426 from authenticating users using PAM under HP-UX. A
2427 workaround using a static variable has been added to
2428 address this problem.
2429 - Fixed a bug in the scheduler SortPrinters() function
2430 that could cause printers to disappear or the
2431 scheduler to crash when adding a printer.
2432 - Changed the pstops filter to not do per-page filtering
2433 if the file does not conform to at least version 3.0
2434 of the document structuring conventions. This seems
2435 to "fix" printing with broken apps.
2436 - The image filters did not handle older TIFF files that
2437 lacked the samples-per-pixel and bits-per-pixel tags.
2438 - Added new cupsGetJobs() and cupsFreeJobs() functions
2439 to manage print jobs.
2440 - cupsEncodeOptions() would encode names of 0 length and
2441 cupsAddOption() and cupsParseOptions() would add names
2443 - The scheduler might block waiting for status messages
2444 after starting a new print job. Thanks to Florent
2445 Guiliani for finding this bug!
2448 CHANGES IN CUPS V1.1.6-3
2450 - The configure script put the JPEG library before the
2451 TIFF library; this caused problems in some
2452 configurations since the TIFF library also supports
2453 JPEG compression of TIFF images.
2454 - Updated the configure script and makefiles to handle
2455 admin man pages with the "1m" extension (HP-UX, IRIX,
2456 Solaris, Tru64) and in odd directories (IRIX)
2457 - The updated cupsTempFile() function did not return
2458 the filename when called with a filename buffer of
2459 NULL (previously it used a static buffer.)
2460 - FreeBSD uses /dev/unlptN, but NetBSD and OpenBSD use
2462 - DeletePrinter() didn't remove the printer from any
2463 classes it was a member of.
2464 - DeletePrinterFromClass() didn't preserve the
2465 implicit status of a class.
2466 - DeletePrinterFromClasses() didn't remove printers
2467 from implicit classes.
2468 - StartJob() didn't send the job-sheets, job-priority,
2469 and job-hold-until attributes to remote printers.
2470 - LoadAllJobs() was looking for job-sheets-completed
2471 instead of job-media-sheets-completed. This would
2472 prevent accumulation of page data after a restart
2474 - The pstops and imagetops filters now generate copies
2475 using the appropriate method for a Level 1, 2, or 3
2476 printer since some Level 2/3 printers don't support
2477 the /#copies variable anymore.
2478 - The man page for cups-lpd did not mention the "-o"
2480 - The IPP backend didn't handle version-not-supported
2481 errors and revert to IPP/1.0 (previously it only checked
2482 for a bad-request error)
2483 - Caldera fix: lpc now reports unimplemented commands as
2484 unimplemented, not invalid.
2485 - Caldera fix: lpq didn't recognize BSD lpq "-a" option.
2486 - Caldera fix: lpr didn't recognize BSD lpr "-1", "-2",
2487 "-3", "-4", "-q", or "-U" options.
2488 - RedHat fixes: patches to GNU Ghostscript
2489 - SuSE fix: temp file creation patch to GNU Ghostscript
2491 - SuSE fix: remove cgi-bin/abort.c and cgi-bin/email.c,
2493 - SuSE fix: missing NULL check in cgi_initialize_post().
2494 - SuSE fix: potential buffer overflows in
2495 cgi_initialize_string().
2496 - SuSE fix: potential buffer overflows in
2498 - SuSE fix: more NULL checks in ppdOpen(); also make
2499 sure that all memory is freed on error to avoid memory
2501 - SuSE fix: Exit from child if setgid() or setuid()
2503 - SuSE fix: Added setgroups() calls after setgid() and
2505 - SuSE fix: potential buffer overflows in httpEncode64()
2507 - SuSE fix: potential buffer overflows in httpSeparate()
2508 - SuSE fix: potential buffer overflows in ippWrite() for
2510 - SuSE fix: potential nul skip in ppd_decode() for
2514 CHANGES IN CUPS V1.1.6-2
2516 - Added changes to support NetBSD startup scripts.
2517 - Added separate compiler options for pstoraster
2518 (Ghostscript) to avoid compiler-induced errors
2519 from Ghostscript's twisted code.
2520 - The mime.types file contained syntax errors.
2521 - Updated the *BSD USB device filenames to use
2522 the /dev/unlptN files so that the USB device
2523 is not reset prior to printing (causes print
2524 corruption on many printers)
2525 - Added new cupsTempFd() function to avoid serious
2526 security bug in glibc fopen() function. The glibc
2527 fopen() function unlinks a file before creating it,
2528 which opens up possible symlink attacks.
2529 - Now reject 0-length names in add-printer and add-class
2531 - Fix for pstoraster when ZLIB is not available.
2532 - cupsGetPPD() didn't reconnect when a HTTP connection
2534 - SuSE fix: httpConnect() didn't check that the
2535 value from gethostbyname() was a valid IPv4 address.
2536 - SuSE fix: httpConnect() didn't allow file descriptor 0
2537 to be used for a socket.
2538 - SuSE fix: ippRead() didn't confirm that all values in
2539 a set were numeric or string types.
2540 - SuSE fix: lppasswd race condition fixes.
2541 - SuSE fix: directive names could overflow buffer when
2542 reading *.conf files.
2543 - SuSE fix: HEAD requests for PPD files did not use the
2544 same logic as GET requests.
2545 - SuSE fix: possible buffer overflow when adding
2546 /index.html to requested directory name.
2547 - SuSE fix: possible buffer overflow when converting
2548 IPP attributes to string options for filters.
2549 - SuSE fix: creating file: device output with mode 0666
2550 instead of mode 0600.
2551 - SuSE fix: creating job info files with mode 0640
2553 - SuSE fix: don't rely on snprintf() for including
2554 system name in log filenames.
2555 - SuSE fix: add bounds checking when copying quoted
2559 CHANGES IN CUPS V1.1.6-1
2561 - Added configure check for getting the correct
2562 strftime() format string; %c is not Y2k safe,
2563 and %KC and NULL are not universally supported.
2566 CHANGES IN CUPS V1.1.6
2568 - Fixed another possible DoS attack in httpGets()
2569 - Added check for "LANGUAGE = PCL" and "LANGUAGE =
2570 POSTSCRIPT" in mime.types.
2571 - Resolution options were not being passed into the
2572 filter programs properly.
2573 - The default compiler options for GCC no longer include
2574 "-g3", which apparently is deprecated in newer
2576 - CheckJobs() could cause cupsd to crash if a job is
2577 cancelled in StartJob().
2578 - The printers.conf and classes.conf files are now
2579 written with restricted permissions.
2580 - The round-robin algorithm used by FindAvailablePrinter()
2581 had problems; fixes contributed by Joel Fredrikson.
2582 - If LoadAllJobs() is unable to determine the file type
2583 of a print job, assume "application/vnd.cups-raw".
2584 - The web interface now provides a job_printer_name
2585 value for any corresponding job_printer_uri value.
2586 - The cups-lpd mini-daemon now logs the client address
2587 and hostname as well as all commands and errors in the
2589 - The IPP backend now detects the supported file formats
2590 and only specifies the document format if it is
2591 supported. This makes IPP printing to network print
2592 servers and cards more reliable without affecting the
2593 capabilities of CUPS servers.
2594 - The time_at_xyz attributes are now converted to human-
2595 readable dates and times for the web interfaces.
2596 - The HP and EPSON sample drivers now correctly catch
2597 signals and eject the current page when a job is
2599 - Fixed bug in CGI code - did not ignore control
2600 characters (e.g. newlines) in form data. This caused
2601 sporatic web interface problems.
2602 - The file type logging code in the scheduler referenced
2603 the optional document-format attribute; the new code
2604 uses the resolved MIME type instead.
2605 - The client.conf parsing code now removes trailing
2607 - The MaxJobs directive was being treated as a boolean
2608 instead of an integer.
2609 - The scheduler would not timeout remote printers if
2610 BrowseInterval was set to 0.
2611 - The lpadmin command now supports setting of options
2612 and user-level access control.
2613 - Added "-E" option to all printing commands to force
2615 - The client code did not consume the response to the
2616 OPTIONS request when switching to secure mode.
2617 - The scheduler did not output a Content-Length field
2618 when responding to an OPTIONS request.
2619 - Added documentation on using cups-lpd with xinetd
2621 - The socket backend now starts retries at 5 seconds and
2622 increases the interval to 30 seconds. This should
2623 provide faster printing when multiple jobs/files are
2624 queued for a printer.
2625 - The filters and backends no longer buffer output to
2626 stderr. This should provide much more accurate status
2630 CHANGES IN CUPS V1.1.5-2
2632 - Fixed configure check for OpenSSL to work with RSA
2634 - Added configure check for <sys/ioctl.h>, and use this
2635 check in backend/serial.c.
2636 - Updated configure script handling of data,
2637 configuration, and state directories to use datadir,
2638 sysconfdir, and localstatedir variables.
2639 - NetBSD uses different serial port filenames than
2640 FreeBSD and OpenBSD.
2641 - The pdftops filter didn't need some X-specific files.
2642 - The scheduler makefile doesn't do a chown anymore when
2643 installing (cupsd did this automatically on startup
2647 CHANGES IN CUPS V1.1.5-1
2649 - There was a typo in the top-level Makefile
2650 - The top-level Makefile did not install an init script
2652 - The configure script did not add the "crypto" library
2653 when checking for the OpenSSL library.
2654 - The OKIDATA PPD files were missing.
2655 - The config.h.in file defined the wrong version number.
2656 - The serial backend did not define "funky_hex" under *BSD.
2657 - Updated the Visual C++ project files and some of the
2658 CUPS API sources to compile under Windows again.
2661 CHANGES IN CUPS V1.1.5
2663 - Security updates - new default configuration does
2664 not broadcast printer information and only allows
2665 access from the local system.
2666 - EXPERIMENTAL encryption support - CUPS now optionally
2667 supports TLS/SSL encryption via the OpenSSL library.
2668 - Documentation updates.
2669 - Makefile/configure script updates.
2670 - The RPM spec file didn't work out-of-the-box under
2672 - Minor code cleanup to remove extraneous compiler
2674 - cupsTempFile() was using %p for the temporary
2675 filename; this should have been %08x (just 8 digit
2677 - Deleting a printer with active print jobs would still
2679 - ippWrite() and ipp_write_file() didn't send the
2680 correct value length for name-with-language and
2681 text-with-language attributes.
2682 - Updated IPP code to support copied strings (that
2683 should not be freed); this provides slightly more
2684 efficient IPP server performance.
2685 - Updated PDF filter to Xpdf 0.91.
2686 - httpGets() could go into an infinite loop if a line
2687 longer than the input buffer size was sent by a
2688 client. This could be used in a Denial-of-Service
2690 - The lpstat and CUPS API functions now request only the
2691 data required when getting the list of printer or
2692 class information. This should improve performance
2693 with large numbers of printers on slower machines.
2694 - The scheduler was always enforcing the FilterLimit,
2695 even if FilterLimit was set to 0.
2696 - Updated the Linux USB backend to support Mandrake's
2697 /dev/usb/usblp# filenames.
2698 - The PRINTER and LPDEST environment variables did not
2699 override the lpoptions default printer.
2700 - The PPD read functions incorrectly included trailing
2701 characters (usually whitespace) after quoted string
2703 - The multiple-document-handling attribute handling code
2704 did not check for the correct value for collated
2705 copies (separate-documents-uncollated-copies).
2706 - The EPSON driver did not work with OKIDATA printers in
2707 EPSON emulation mode (needed change-emulation command)
2708 - The HP-GL/2 filter did not scale the plot properly in
2710 - Added PPD files for 9-pin and 24-pin OKIDATA printers.
2711 - The httpSeparate() function didn't handle passwords
2712 that started with a number.
2713 - ippDelete() could free the character set string
2714 multiple times in name-with-language and
2715 text-with-language attributes.
2716 - The scheduler would access freed memory right after
2717 freeing it (for debug messages); these parts of the
2718 code have been reordered to avoid this situation
2719 which was causing sporatic errors and crashes.
2720 - The ppdClose() function didn't free all of the strings
2721 in the ppd_file_t structure.
2722 - The LoadAllJobs() function in the scheduler did not
2723 close the spool directory.
2724 - Changed all sprintf's that use string formats to
2725 snprintf's, even if the destination buffer is
2726 larger than the source string(s); this protects
2727 against buffer overflows caused outside of CUPS...
2728 - Changed all strcpy's to strncpy's between local and
2729 global variables, even if the destination buffer is
2730 larger than the source string; this protects
2731 against buffer overflows caused outside of CUPS...
2732 - The CUPS certificate functions didn't use the
2733 CUPS_SERVERROOT environment variable when set.
2734 - The directory services code was copying instead of
2735 comparing the remote printer info, resulting in
2736 unnecessary updates of the printer attributes for
2738 - Added new mime.types rules to allow automatic raw
2739 printing of PCL and ESC/P files; PJL headers are
2740 parsed to differentiate between PostScript and
2741 PCL job files. This should eliminate a lot of
2742 the reports of SAMBA printing problems due to
2743 the missing "-oraw" or "-l" options.
2744 - The mimeLoadType() function didn't handle the
2745 3-argument contains() function.
2746 - The LoadPPDs() function in the scheduler didn't
2747 properly set the alloc_ppds variable or handle a PPD
2748 database containing 0 printers.
2749 - The scheduler FindAvailablePrinter() function didn't
2750 use the same queuing logic as the CheckJobs()
2751 function. This caused classes to stall if a remote
2752 printer was always busy.
2753 - Jobs are now assigned to printers in a class
2754 round-robin style. This should prevent the first
2755 server in the class from bearing the brunt of the
2757 - The scheduler's LoadAllJobs() function didn't always
2758 restore remote printers for queued jobs on startup.
2759 - The serial backend didn't support the higher baud
2760 rates with the old termios interface. It now supports
2761 57600 and 115200 baud.
2762 - The serial backend now supports different types of
2763 flow control; previously it ignored the flow=XYZ
2764 option in the device URI.
2765 - The serial backend now supports DTR/DSR flow control,
2766 which is popular on dot-matrix printers (access with
2767 "flow=dtrdsr" in the device URI)
2768 - Added new job-originating-host-name attribute for
2769 jobs. The new attribute provides the hostname or
2770 IP address of the machine that submitted the job.
2771 - The set-job-attributes code no longer allows read-only
2772 job attributes to be changed.
2773 - Expanded the click area for the navigation bar in the
2775 - Updated the lp and cancel commands to support all of
2776 the Solaris print options (some are simply ignored
2777 since they do not map)
2778 - Updated the scheduler to limit the number of file
2779 descriptors to the maximum select() set size. This
2780 was causing problems on Solaris systems where the
2781 max FD count was increased beyond 1024.
2782 - The scheduler's LoadDevices() function was getting
2783 interrupted by the SIGCHLD signal handler; now ignore
2784 child signals while loading devices.
2785 - Added quota and allow/deny user support for printers
2787 - Removed black/CMY adjustment code from the PS and
2788 image file RIPs; it was interfering with some CUPS
2789 driver dithering code.
2790 - The lpc program stopped listing the queue statuses
2791 after the first active printer.
2792 - The cups-lpd program used an output format that the
2793 Solaris printing system did not understand.
2794 - Updated the lpq program to use the Solaris format
2795 except under Tru64 UNIX.
2796 - Some DEC PPD files incorrectly use "Off" for the null
2797 value in UI constraints. Added "Off" to the list of
2798 accepted null values.
2799 - Changed the *BSD define constants to __*BSD__ in all
2801 - Added support for "lpstat printername", which is an
2802 undocumented feature in Solaris.
2803 - The HP-GL/2 filter now only sets the plot size if it
2804 is set in the plot file.
2805 - The lpmove command wasn't sending the requesting
2806 user name, causing it to always fail.
2807 - Updated the cupsTempFile() code to use GetTempPath()
2809 - The cups-lpd mini-daemon didn't limit the number of
2810 data files accepted, didn't use cupsTempFile(),
2811 didn't handle control file job information in any
2812 order, and didn't free job options after printing
2814 - The scheduler copy_banner() function did not
2815 explicitly set the owner and permissions of the banner
2816 files, which could prevent the banner pages from
2817 printing on some systems.
2818 - The lpstat program wasn't listing remote classes.
2819 - The scheduler did not verify that the printer-uri
2820 attribute was specified in all requests that required
2824 CHANGES IN CUPS v1.1.4
2826 - Makefile and configure script fixes.
2827 - **** Changed the default Printcap setting **** to
2828 /etc/printcap. There are just too many people asking
2829 why application XYZ doesn't see their printers!
2830 - The web admin interface now displays an error if it
2831 can't get the list of printer drivers from cupsd.
2832 - The IPP backend was putting the copies option before
2833 the other job options were set. This caused the IPP
2834 request to contain attribute groups in the wrong
2835 order, which prevented remote printing.
2836 - Added checks in scheduler to free memory used for
2837 IPP requests and language information when closing
2838 a client connection.
2839 - Fixed the duplex option in the HP LaserJet driver. It
2840 should now work with all LaserJet printers (and
2842 - The add-printer web interface didn't initialize the
2843 "old info" data pointer, which caused random crashes
2845 - Fixed many page sizes defined in the Level 1
2846 compatibility file "gs_statd.ps" to match reality.
2847 - Fixed another bug in the setpagedevice "code" in
2848 Ghostscript. It should now accept all standard
2849 Adobe attributes on all platforms.
2850 - Fixed pstoraster so that it reallocates memory for
2851 color depth changes as well as size/resolution
2852 changes. This removes an ordering constraint on
2853 the color, page size, and resolution options in
2855 - The IPP backend didn't use the job's character set
2856 when the destination printer supported it. This
2857 caused problems when printing text files to other
2859 - Updated the logic used to determine when to rebuild
2860 the PPD file database. The scheduler now checks the
2861 dates and the number of PPD files (was just checking
2863 - Updated the ippSetCGIVars() function (used by the
2864 web interfaces) to only filter valid string values.
2865 - The PostScript filter was scaling 2-up pages
2866 incorrectly. This caused the edges of some pages to
2870 CHANGES IN CUPS v1.1.3
2873 - RPM spec file changes.
2874 - Documentation updates.
2875 - Enabled pstoraster debug messages for everything
2876 (only logged when LogLevel set to "debug"...)
2877 - Changed the Input/OutputAttributes fix in
2878 pstoraster so that it works on all platforms.
2879 - The HP-GL/2 filter didn't set the right green
2880 color value in encoded polylines or text.
2881 - Updated the "fitplot" code to handle plot sizes
2882 specified as "PSwidth,length" and "PSlength,width".
2883 - Updated the Linux parallel and USB backends to open
2884 the device files prior to looking in /proc for
2885 autoprobe info. This makes sure that loadable device
2886 driver modules are in fact loaded...
2887 - Added new FilterLimit directive to limit the number
2888 of processing jobs/filters on a system.
2889 - set-job-attributes didn't change the job-state to
2890 held/pending when the job-hold-until attribute was
2892 - set-job-attributes didn't save the new job attributes.
2893 - Now change the "requesting-user-name" attribute in
2894 requests from remote systems to "remroot" when an
2895 unauthenticated "root" user is sent. This can be
2896 changed using the new RemoteRoot directive in
2898 - The cancel-job, hold-job, release-job, and restart-job
2899 operations didn't log the authenticated username.
2900 - The cups-lpd mini-daemon now checks for a
2901 document-format option before forcing raw mode with
2903 - The cups-lpd mini-daemon now supports "-o" options
2904 on the command-line (passed by inetd) to set global
2905 defaults for all print queues.
2906 - The pstops filter assumed that a file with a Trailer
2907 comment would also have an EOF comment.
2908 - Added new cupsSetPasswordCB(), cupsSetServer(),
2909 cupsSetUser(), and ippSetPort() functions to better
2910 support client applications (especially GUIs...)
2911 - The CUPS-add-class and CUPS-add-printer operations
2912 didn't reset the printer-name attribute on remote
2913 print queues that had to be renamed when a local
2914 printer was defined with the same name.
2915 - The lpoptions command now supports a "-r" option to
2916 remove options for a printer or instance.
2917 - The lpadmin and admin.cgi programs no longer allow
2918 class and printer names to begin with a number; this
2919 caused the command-line utilities to become confused.
2920 - The Linux USB backend now looks for both the parallel
2921 and usblp driver names in the device list.
2922 - Added a new FontPath directive to cupsd.conf, and also
2923 a "--with-fontpath" option for the configure script to
2924 specify alternate font paths for pstoraster.
2925 - The CUPS-move-job operation didn't update the
2926 job-printer-uri attribute.
2927 - The scheduler only looked up printers and classes by
2928 name in IPP requests, instead of using the full URI.
2929 This caused problems with KUPS and friends with
2931 - The scheduler now handles better localization of
2932 hostnames (e.g. server is host.foo.com, remote is
2933 host.subfoo.foo.com, localized is not host.subfoo...)
2934 - The scheduler logging functions now use a common
2935 log file checking/rotation function (courtesy of
2936 Crutcher Dunnavant at Red Hat)
2937 - The scheduler could accept more client connections
2938 than it allocated for if more than one Port or Listen
2939 line was present in cupsd.conf.
2940 - Other minor scheduler performance tweeks.
2941 - The lpq and lprm commands didn't support the default
2942 printer set using lpoptions.
2943 - The lpoptions command now supports a "-l" option to
2944 list the printer-specific options and their current
2946 - The web printer and class lists now show a link to the
2947 default printer or class at the top of the page.
2948 - The text filter now supports pretty printing of shell
2949 and perl scripts as well as C/C++ source files.
2950 - The top and bottom margins were reversed for landscape
2952 - The lpq and lprm commands didn't understand printer
2954 - The scheduler only selected on the first 100 file
2955 descriptors instead of the maximum file descriptor
2957 - The scheduler client, listener, and mainline functions
2958 now share code to disable and enable monitoring for
2959 new client connections.
2960 - The imagetoraster filter didn't support all of the
2961 required pagedevice parameters.
2962 - The serial backend now checks for 100 serial ports
2964 - The scheduler used sscanf() to pull out the remote
2965 printer location, description, and make/model strings,
2966 but if any of these options was empty then sscanf()
2967 would stop processing.
2968 - Added "debug2" log level to provide a little less
2969 verbose debugging information at the "debug" level.
2970 - The scheduler would crash if you stopped a printer
2971 that was currently printing a job.
2972 - The scheduler incorrectly allowed jobs in the cancelled,
2973 aborted, or completed state to be cancelled.
2974 - The image filters did not load TIFF images properly
2975 for bottom-to-top and right-to-left orientations.
2976 - Added new cupsEncodeOptions() function to encode
2977 CUPS options as IPP job attributes.
2978 - The IPP backend, LPD mini-daemon, client commands,
2979 and CUPS API did not properly encode multiple
2980 option values separated by commas.
2981 - Added new scheduler malloc logging in debug mode
2982 (provides summary of total arena size, allocated,
2983 and free bytes once a minute)
2984 - The EPM-based distributions didn't install the
2985 correct symlinks for a few man pages.
2986 - Fixed a memory leak in the scheduler - wasn't
2987 freeing old filters when deleting or renaming
2989 - The scheduler now queries the primary IP address
2990 for the name of the server and maps any incoming
2991 requests from that address to the server name.
2992 This fixes web admin mapping problems from
2993 server.domain.com to localhost.
2994 - The web printer modify interface now remembers
2995 the previous device and driver settings (except
2997 - The job-k-octets attribute is now stored as part of
2998 the job attributes; this preserves the information
2999 after a job is completed when job file history is
3001 - Dropped option sub-group parsing code for the moment,
3002 since many Xerox PPD files abuse this feature in PPD
3003 files and don't follow the hierarchy rules.
3004 - Added new wrapper code around options so that duplex
3005 options for some HP printers don't prevent prints.
3006 - Added support for Digital UNIX/Tru64 UNIX/OSF/1 format
3007 for "lpstat -v" output.
3008 - Now show the URI for remote printers instead of
3009 /dev/null in "lpstat -v" output.
3010 - Creating classes and adding printers to a class with
3011 the lpadmin command didn't work.
3012 - The banner pages and test page should now format
3013 correctly in both portrait and landscape orientations.
3014 - Updated banner page substitution so that { can appear
3015 by itself without quoting.
3018 CHANGES IN CUPS v1.1.2
3020 - Makefile/configure fixes
3021 - RPM spec file and EPM list file fixes
3022 - The cupsTempFile() function now uses a different
3023 algorithm for generating temp files and "reserves"
3024 them to avoid possible security exploitation.
3025 - Now use /dev/random (if available) to seed the random
3026 number generator for certificates.
3027 - The /var/spool/cups and /var/spool/cups/tmp directories
3028 were incorrectly owned by root; they are now owned by
3029 the filter user, typically "lp".
3030 - The scheduler now resets the permissions on the spool
3031 and temp directories as needed to match the filter
3033 - Now expose ppdCollect() as an externally callable
3035 - The image filters now support filtering from the
3037 - The imagetoraster filter now collects all printer
3038 options and job patch files and applies them to the
3039 page header as needed.

3041 - The send-document operation didn't start a job
3042 immediately when last-document was true.
3043 - The set-job-attributes operation didn't correctly
3044 replace the current job-hold-until value.
3045 - Removed the option wrapper code from ppdEmit() and
3046 friends since it caused problems with Ghostscript
3047 and many PS printers.
3048 - Was setting TZ environment variable twice for job
3050 - Added syslog logging in cups-lpd to aide in
3052 - The HP-UX parallel port backend did not list the
3053 available parallel ports on some systems (printf
3055 - The lp and lpr commands overrode user options if
3056 -d/-P were specified after -o.
3057 - The scheduler would crash with a */* filter.
3058 - Added support for a "default" filter for unknown file
3059 types. The example provided in the mime.types and
3060 mime.convs file prints unknown files as if "-oraw" was
3061 specified for the job. This functionality is disabled
3063 - The "compatibility" mode fix for older backends did not
3064 work for smbspool. Added a workaround for it.
3065 - The HP-GL/2 filter didn't perform the right pen scaling
3066 with some files and the "fitplot" option.
3067 - New Software Performance Specification document that
3068 describes the memory, disk, and CPU usage of all the
3072 CHANGES IN CUPS v1.1.1
3074 - The pstoraster Makefile still referenced one of the
3075 old PDF filter files.
3076 - The filter Makefile used INSTALL_DATA instead of
3077 INSTALL_LIB to install the CUPS image library.
3078 - The administration CGI didn't work properly with
3080 - The BrowseACL variable was not updated after the
3081 cupsd.conf file was loaded.
3082 - The lpd mini-daemon didn't support printer instances.
3083 - Now use a default umask of 077 for child processes.
3084 - Now put temp files in /var/spool/cups/tmp for child
3085 processes and the root user, unless TMPDIR or TempDir
3086 is defined otherwise.
3087 - cupsGetPPD() no longer uses easy-to-guess filenames.
3088 - The CUPS-Delete-Class and CUPS-Delete-Printer
3089 operations now save classes.conf file as needed.
3090 - The lppasswd command wouldn't add a user.
3091 - The ppdOpen() function could cause a segfault if a
3092 0-length PPD file was read.
3093 - The image filters were not handling images with
3094 different X and Y resolutions properly.
3095 - The imagetoraster filter defaulted to RGB output
3096 instead of black output like pstoraster.

3101 documents if they don't have it.
3102 - The cupsGetPPD() function didn't work with remote
3103 printers lacking the @server in the name.
3104 - The configure script didn't work right when only
3105 --prefix was specified.
3106 - The ppdEmit() code now wraps all printer commands so
3107 that buggy PostScript printers will still print a file
3108 after receiving an option that isn't available.
3109 - Fixed the DeskJet margin bug, and disabled 600dpi
3110 color mode until it can be fixed.
3111 - The cupsAddDest() function didn't sort instances
3112 correctly in all cases.
3113 - The time-at-xyz attributes now expand to the date and
3114 time in banner files.
3117 CHANGES IN CUPS v1.1
3119 - Documentation updates.
3120 - Configuration script updates.
3121 - Didn't map charset and language value strings to lowercase
3122 and _ to - as required by SLP and IPP.
3123 - ppdLoadXYZ() didn't add the list of available fonts to the
3124 ppd_file_t structure.
3125 - The text filter common code was freeing the PPD file data
3127 - The text filter now embeds missing fonts.
3128 - The CGI interface now maps local access to the server to
3129 the localhost address.
3130 - The HP-GL/2 filter didn't use the specified (or default)
3131 color ranges, resulting in strange colors.
3132 - The HP-GL/2 filter didn't default to no input window, which
3133 caused unnecessary clipping of plots.
3134 - Integrated Xpdf's pdftops filter into CUPS, which is a
3135 lightweight and reliable replacement for Ghostscript's
3137 - Removed all PDF support from Ghostscript.
3138 - Updated HP driver to set top margin; this seems to fix
3139 the offset problem seen on HP DeskJet printers.
3140 - Fixed dependencies on the ZLIB and JPEG libraries in
3142 - The lpr command wasn't using the lpoptions defined by
3144 - The lpr command would segfault if the CUPS server was
3146 - The top-level makefile was not installing the CUPS
3147 initialization script. It now does so if it sees there
3148 is an init.d directory in /sbin, /etc/rc.d, or /etc.
3149 - "lpstat -v all" didn't work.
3150 - pstoraster would crash on some platforms doing the

3156 - The AccessLog, ErrorLog, and PageLog directives now
3157 support "%s" to insert the server name.
3158 - Added a new BrowseShortNames directive to allow for
3159 short remote printer names ("printer" instead of
3160 "printer@server") when possible.
3161 - The scheduler could crash if given an invalid PPD file
3162 with no PageSize attributes.
3163 - Updated the serial, parallel, and usb backends to do
3164 multiple writes and ignore ioctl() errors as needed;
3165 this should fix problems with serial printing on old
3166 serial drivers and with the UltraSPARC parallel port
3167 driver under Solaris 2.7.
3168 - Now propagate LD_LIBRARY_PATH to child processes from
3170 - New DataDir directive for installing in alternate
3172 - New CUPS_SERVERROOT and CUPS_DATADIR environment
3173 variables to specify installation directories as

3181 - Wasn't updating time-at-processing and
3182 time-at-completed attributes in job.
3183 - Didn't send required multiple-operation-time-out
3184 attribute in response to a get-printer-attributes
3186 - cups-lpd now supports options set with lpoptions.
3187 - The job-hold-until attribute is now provided with all
3188 jobs. For jobs that are not currently held the value
3190 - The scheduler was not sending "unknown" values in IPP
3192 - The lpoptions command now accumulates options from
3193 previous runs rather than replacing all options for a
3195 - The IPP backend now switches to IPP/1.0 if a 1.1
3197 - The lpadmin and admin.cgi programs now validate new
3198 printer and class names.
3199 - The access_log file now includes the number of IPP bytes
3200 received in a POST request.

3212 - Missing the job-restart template.
3213 - Added IPP test suite for testing.
3214 - Missing IPP documentation from binary distributions.

3217 - Added more checks to IPP requests to prevent bad requests
3218 from getting through.
3219 - Not all of the Ghostscript error output was being sent to
3221 - The PostScript filter now added PJL commands to set the
3222 job name and display string, if supported.
3223 - The scheduler would crash if the browse socket could not
3224 be bound. Now disables browsing if port 631 (reserved for
3225 IPP) is being used by a misbehaving daemon.
3226 - The USB backend now looks for the older Linux 2.2.x USB
3227 printer device filenames as well as the newer ones.
3228 - The IPP backend now uses the UTF-8 charset exclusively,
3229 since apparently only CUPS handles more than US-ASCII and
3231 - Wasn't quoting ( in PostScript banners...
3232 - Send-document requests with no document-format attribute
3233 could cause cupsd to crash.
3234 - Old jobs in the spool directory might cause cupsd to
3236 - CUPS now supports all of the recommended job-hold-until
3237 keywords as well as name values of the form "HH:MM" and
3239 - Added placeholder pointer for TLS encryption to the HTTP
3240 connection structure.
3241 - Fixed the "fast poll" bug reported by DISA - the
3242 status pipe wasn't being closed for multi-file jobs.
3243 - Revamped put_params code in pstoraster to fix bitmap
3244 allocation bug with FrameMaker output.
3245 - Ripped out filename, etc. code from pstoraster as it
3246 is a potential security hole.
3247 - Added support for RIP_CACHE environment variable in the
3249 - Fixed USB device filenames for Linux; now support new
3250 pre-2.4 devices (/dev/usb/lp#) and 2.2 devices
3252 - Fixed accept-jobs crash with classes.
3253 - Didn't include dot-matrix EPSON drivers in previous
3257 CHANGES IN CUPS v1.1b4
3259 - Documentation updates.
3260 - Many makefile and configuration script fixes (should
3261 now compile better under *BSD.)
3262 - The MediaPosition attribute was being mishandled by
3263 GhostScript, causing the RIP to fail whenever a paper
3265 - The scheduler now logs the final line of log information
3266 from a filter, even if it doesn't end with a newline; this
3267 primarily affects GhostScript error output.
3268 - The scheduler was saving implicit classes, so after a few
3269 restarts you'll end up with AnyPrinter, AnyAnyPrinter, etc.
3270 - The JPEG autodetection didn't work with some JPEG files that
3271 came from digital cameras (JPEG but not JFIF); the new
3272 magic types should work with all images that the JPEG library
3274 - Fixed a bug in the new contains() MIME type rule that could
3275 cause cupsd to crash.
3276 - Switched to using strtol() in the MIME type code so that you
3277 can use hex, octal, or decimal constants as desired in the
3279 - Banner files are now treated as templates, allowing any type
3280 of file to be used as a banner.
3281 - Added a 30-second timeout to backend device reports so that a
3282 hung backend will not prevent the scheduler from starting.
3283 - Backends are once again terminated when jobs are stopped; the
3284 CUPS-supplied backends will stay alive until the downstream
3285 filters have had a chance to clear out old page data.
3286 - The charset lookup in the CUPS localization support was wrong
3287 (iso8859-x instead of iso-8859-x)
3288 - Changed the "cpNNNN" code page files to "windows-NNNN" to match
3289 the IANA registrations.
3290 - New PostScript banner pages.

3299 keep track of the total number of pages in the
3300 job-media-sheets-completed attribute.
3301 - The penwidth option is now in micrometers to support more
3302 accurate width specification.
3303 - The image filters now support interlaced and transparent PNG
3305 - Didn't handle Keep-Alive for HTTP/1.0 clients.
3306 - The BrowsePoll support didn't handle when BrowseInterval
3307 was set to 0 (now uses 30 seconds if BrowseInterval is 0)
3308 - The DeskJet driver now supports 600 DPI color for printers
3310 - New lpinfo and lpmove commands.

3318 matching the behavior of the System V command.
3319 - The "cancel -a" command now purges job history files.
3322 CHANGES IN CUPS v1.1b3
3324 - Documentation updates.
3325 - The startup script redirected stderr before stdout,
3326 which caused problems with some versions of Bourne
3328 - Fixed a bug in the scheduler's PPD language reading

3339 - The default printcap file is now empty (no printcap
3341 - The scheduler did not start jobs destined for remote
3342 printers when they became available.
3343 - The scheduler now sends jobs to remote printers
3344 immediately. (when sending jobs to a class, the remote

3375 - The web admin interface now supports class management.
3376 - The web admin interface now shows a list of
3377 manufacturers before selecting the PPD/driver for a

3399 so that the default server can be configured on a per-user
3400 basis without environment variables.
3401 - Added LPD mini-daemon to support incoming LPD jobs.
