10 - Mike Bytnar provided a fine report that proved that the --with-ssl option
11 for configure needed tweaking. It no longer searches the default directories
12 for OpenSSL libs or directories when a specified path is given.
15 - When an FTP transfer is cut off during transfer, curl could present a truly
16 garbaged error message and in worst case dump core. Thanks to detailed
17 reports from Shawn Poulson we nailed this.
20 - Salvador Dávila provided a fix for FTP range downloads.
22 - Added a few more test cases from the former test suite to the new file
23 format. We're now at a total of 26 tests.
26 - libcurl's version-info was wrong, as noted by both Domenico Andreoli and
30 - Jörn fixed the curl_unescape duplicate entry in lib/libcurl.def
32 - I made SSL certificate failure messages to be more detailed.
37 - SDavila provided a resumed download fix.
42 - Sterling provided some new PHP examples.
44 - Changed the CVS hierarchy and the older checkout instruction does no longer
45 work. We moved the entire source code into a CVS module named 'curl'.
48 - CURLOPT_MUTE does not exist anymore. It is still present in the include file
49 to not cause compiler errors for applications using it, but it isn't used
50 anywhere in the library.
55 - Once and for all fixed the _REENTRANT mess for Solaris compiles to present
58 - Sterling Hughes tirelessly points out and corrects my mistakes...! So,
59 curl_global_init() now lets the argument flags *SET* what parts to
60 init. CURL_GLOBAL_DEFAULT makes a nice default, CURL_GLOBAL_ALL inits all
61 known subsystems and CURL_GLOBAL_NONE inits nothing more than absolutely
62 necessary. Man page updated accordingly.
64 - Fixed the strtok.h include file as it wouldn't compile on all platforms!
67 - Made libcurl by default act as if CURLOPT_MUTE and CURLOPT_NOPROGRESS were
68 set TRUE. Set them to FALSE to make libcurl more talkative. The *_MUTE
69 option is subject for complete removal...
74 - Cris Bailiff wrote a makefile for building Solaris packages.
76 - Sterling Hughes brought fixes for 'buildconf' (the build-from-CVS tool) and
77 we discussed and added a few CURL_GLOBAL_* flags in include/curl.h
79 - Kjetil Jacobsen privately announced his python interface to libcurl,
80 available at http://pycurl.sourceforge.net/
83 - Sterling Hughes fixed a strtok() problem in libcurl. It is not a thread-
84 safe function. Now configure checks for a thread-safe version, and
85 lib/strtok.c offers one for the systems that don't come with one included!
87 - Mettgut Jamalla correctly pointed out that the -# progress bar was written
88 to stderr even though --stderr redirection was used. This is now corrected.
90 - I moved out the list of contributors from the curl.1 man page and made a
91 separate docs/THANKS file. It makes the list easier to find, and made it
92 easier for me to make a separate web page with that same information.
94 I really do want all you guys mentioned in there to feel you get the credit
97 - lib/easy.c didn't compile properly in the 7.8-pre1 due to a silly mistake
102 - curl-config now supports '--vernum' that outputs a plain hexadecimal version
103 of the libcurl version number (using 8 bits for each 3 numbers). Version
104 7.7.4 appears as 070704
106 - Wrote man pages for curl_global_init and curl_global_cleanup...
108 - T. Bharath brought news about the usage of the OpenSSL interface that was
109 not previously taken into consideration and thus caused libcurl to leak
110 memory. The only somewhat sane approach to fix this dilemma, is adding two
111 two new functions curl_global_init() and curl_global_cleanup() that should
112 be called *ONCE* by the application using libcurl. The init should be done
113 only at startup, no matter how many threads the application is gonna use,
114 and the cleanup should be called when the application has finished using
117 *** UPGRADE NOTICE ***
119 If you write applications using libcurl, you really want to use the two
120 functions mentioned above !!!
122 I can't say I think this is a very beautiful solution, but as OpenSSL
123 insists on making lots of stuff on a "global" scope, we're forced to walk
124 the path they point us to.
126 - Moving more test cases into the new file format.
131 - Introduced a new file format for storing test cases, and thus I had to
132 modify all the perl test scripts and more (I added a new one). I have not
133 "ported" all the old test cases to the new format yet, but it'll come.
135 The main advantage of this new format is that all test data for each test
136 case is stored in a single file. It gives a better overview for each test
137 case and a lot less files.
139 - Andrés García brought a fix for the netscape/mozilla cookie file parsing
140 function, as it turns out it doesn't always store the path!
143 - As was reported anonymously, when FAILONERROR was used, the httpcode was
144 not stored properly and thus wasn't possibly to read after a transfer with
145 the curl_easy_getinfo() function. This is now corrected.
147 - Installed and made use of the following tool versions:
152 I wouldn't recommend any developer to try to generate things with older
153 versions than these. Building from CVS will probably more or less require
154 at least these versions.
156 As a result of this, the configure script grew to more than double its
159 Arkadiusz Miskiewicz helped me by pointing out I had to remove my
160 acinclude.m4 file before I could get it working!
163 - I made ftps:// work. Added test case 400 to the release archive, as the
164 first ftps:// test case. Requires stunnel.
166 - Also made the test cases that runs ssl tests not run if libcurl isn't built
170 - Made the configure not add any extra -L LDFLAGS or -I CPPFLAGS unless they
171 are actually needed. Albert Chin's and Domenico Andreoli's suggestions
177 - Nicer configure-check for the OpenSSL headers, which then sets the proper
178 variable to have curl-config be good. (Albert Chin provided the fix)
180 - For systems that don't have theiw own 'strlcat()' libcurl provides its own.
181 It was now renamed to prevent collides with other libs. (After discussions
182 with Sterling Hughes and the implications this had on PHP builds.)
185 - Colm Buckley posted a detailed bug report on (the debianized) 7.7.3, that
186 turned out to be a problem with the debian-built 7.7.3-package that
187 contained files from the 7.7.2 release!
189 - I added the CURLE_ALREADY_COMPLETE again, but with a fake value, just to
190 make programs that use it, not fail when compiling against this version of
194 - Pawel A. Gajda fixed a problem with resumed transfers on re-used persistent
200 - Jun-ichiro itojun Hagino fixed FTP PORT for IPv6-enabled libcurl.
202 - Added the first HTTPS test to the test suite in the release archive.
205 - Jukka Pihl suggested that if (lib)curl is told to verify the peer's
206 certificate and the peer can't be verified, it should fail and return a
207 proper error code. I added a brand new error code named
208 CURLE_SSL_PEER_CERTIFICATE for this purpose.
211 - As was discussed with Frederic Lepied a while ago, I now made libcurl not
212 return error even though no data was transfered on upload/download resume
213 when the no transfer is needed. The CURLE_ALREADY_COMPLETE error was removed
214 from the header file to make any implemenator that uses that to be aware of
215 the fact that it can't be returned anymore!
217 - Improved general header-parsing to better allow white spaces and more.
219 - Rodney Simmons proved the fix I did yesterday was bad and I had to post
222 - Ingo Wilken patched away two redirect problems more!
225 - Cris Bailiff correctly noted that the space-after-header problem with
226 Location: is present on several other places in the libcurl sources.
228 - Ingo Wilken patched away a problem libcurl had when following Location:
229 headers with an extra space after the colon.
231 - Rodney Simmons found out that multiple FTP transfers did not treat relative
232 directories correctly.
235 - Getting an FTP file with CURLOPT_NOBODY set (or -I from the command line),
236 makes curl use the non-standard ftp command "SIZE". If it failed, libcurl
237 returned error. Starting now, it just don't output the file size instead.
238 Anonymous bug report.
240 - stunnel.pm was accidentally left out from the release archive, it is now
241 added (stunnel is needed to run the https-tests in the test suite)
244 - Corrected two minor compiler warnings due to the FILE * to void * conversion
245 that I missed at two places. Jörn Hartroth brought me patches. Sander Gates
246 filed a bug report on this.
251 - All callback functions now take 'void *' instead of 'FILE *'. This is made
252 this way to make it more obvious to people that anything can be passed to
253 them (by using the apropriate option). After discussions with Sterling
257 - Cris Bailiff fixed a chunked transfer encoding problem with persistent
258 connection that made libcurl fail if the persistent connection used mixed
259 chunked and non-chunked transfers.
261 - Cris Bailiff fixed a bad treatment of 304-replies, as they would not be
262 treated as content-length 0 replies but would cause a "hang" until the
263 server timed-out and closed the connection.
265 - Brad Burdick found a minor problem in the docs/examples/Makefile.am
267 Daniel (27 April 2001)
268 - Updated the INTERALS document again. It was lagging a bit. I think I made it
269 more easy to follow now as well.
271 - Brad Burdick found a problem with persistent connections when curl received
272 a "Content-Length: 0" header.
274 - Giuseppe D'Ambrosio was first out to report that TELNET doesn't work in curl
275 compiled/built on win32. It seems to work for unixes though!
277 - Dave Hamilton reported weird problems with CURL/PHP that I really can't
278 explain at the moment. I'm hoping on some help from the PHP crew.
280 Daniel (26 April 2001)
281 - I rewrote the FTP command response function. I had to do it to make ftps
282 work, as the OpenSSL read()-function didn't work the same way the normal
283 unix read() does, but it was also a huge performance boost. Previously the
284 function read one byte at a time, now it reads very large chunks, and it
285 makes a notable speed difference.
287 Daniel (25 April 2001)
288 - Connection re-use when not using a proxy didn't work properly for
289 non-default port numbers.
291 Daniel (24 April 2001)
292 - I've noticed that FTPS doesn't work. We attempt to use ssl even for the
293 data transfer, which causes the transfer to 'hang'... We need to fix this.
295 - Improved the test suite to use 'stunnel' to do HTTPS and FTPS testing on
296 the alredy written perl servers easily.
298 Daniel (23 April 2001)
299 - The OpenSSL version string recently modified didn't zero terminate one
300 of the generated strings properly, which could lead to a crash or simply
301 weird version string output!
305 Daniel (22 April 2001)
306 - Rosimildo da Silva updated the Makefiles for Borland/Windows.
308 - Eric Rautman pointed out a problem with persistent connections that would
309 lead to broken Host: headers in the second HTTP request.
311 Daniel (20 April 2001)
312 - Added man pages for the curl_strequal() and curl_mprintf() families. Wrote
313 a 'libcurl overview' man page.
315 - Spell-fixed some documents.
317 - S. Moonesamy corrected mistakes in the man page.
319 - Cris Bailiff fixed the curl_slists options in the perl interface, present
320 separately in the Curl::easy 1.1.4 package.
322 Daniel (19 April 2001)
323 - Linus Nielsen Feltzing removed the decimals from the size variables in the
324 --write-out output. We hardly ever get fraction of bytes! :-)
328 Daniel (19 April 2001)
330 - Albert Chin provided a configure patch for the AC_SYS_LARGEFILE macro.
332 Daniel (18 April 2001)
333 - Input from Michael Mealling made me add --feature to curl-config. It
334 displays a list of features that have been built-in in the current
335 libcurl. The currently available features that can be listed are: SSL, KRB4
338 - I committed Cris and Georg's perl interface work. They've got callbacks
339 working and options that receives those slist pointers.
341 - Puneet Pawaia detected a problem with resumed downloads that use persistent
342 connections and I made a rather large writeup to correct this. It is
343 important that all session-data is stored in the connectdata struct and not
344 in the main struct as this previously did.
346 Daniel (17 April 2001)
347 - Frederic Lepied fixed a ftp resumed download problem and introduced a new
348 error code that lets applications be able to detect when a resumed download
349 actually didn't download anything since the whole file is already present.
350 Should this return OK instead?
352 - I added 'curl-config.in' to the root dir and configure script. Now, a
353 curl-config script is made when curl is built. The script can be used to
354 figure out compile time options used when libcurl was built, which in turn
355 should be options YOU should use to build applications that use libcurl.
357 This *-config style is not a new idea, but something that has been used
358 successfully in other (library based) projects.
360 - Phil Karn pointed out that libcurl wrongly did not always use GMT time zone
361 for the If-Modified-Since style headers.
363 - Georg Schwarz pointed out an extra needed #include file needed in src/main.c
364 for curl to build on Ultrix.
366 Daniel (11 April 2001)
367 - Cris Bailiff pointed out two problems that I corrected. First, libcurl's use
368 of the environment variable HTTP_PROXY in uppercase may become a security
369 hazard when people use libcurl in a server/cgi situation where the server
370 sets the HTTP_*-variables according to incoming headers in the HTTP
371 request. Thus, a "Proxy:"-header would set that environment variable!
373 Then, invoking curl_easy_perform() without having an URL set caused a crash.
375 - S. Moonesamy brought a patch that make curl use non-blocking connects on
376 windows when connection timeout is set, as it allows windows users to set
379 - Hirotaka Matsuyuki wrote a Ruby interface to libcurl!
381 - Cris Bailiff, Forrest Cahoon and Georg Horn work on the Perl interface.
383 - I've written a first shot at a Java interface to libcurl. Many thanks to
384 Daniel Marell for tirelessly answering to all my basic Java questions. It
385 works, but it is still very basic.
387 Daniel (10 April 2001)
388 - The progress display could get silly when doing multiple file transfers, as
389 it wasn't properly reset between transfers!
391 - Discussions with Cris Bailiff who writes a Perl interface to libcurl, made
392 me add CURLOPT_HEADERFUNCTION. It can be used to set a separate callback
393 function for writing headers. Previously you could only set a different FILE
394 * when headers are written from within libcurl.
396 Daniel (7 April 2001)
397 - Andrés García fixed a problem in curl_escape() and pointed out a flaw in
398 the curl_easy_setopt man page.
400 Daniel (6 April 2001)
401 - Adjusted the version code to properly display OpenSSL 0.9.6a. They sure
402 change their version define format often...
404 - curl_formfree() now accepts a NULL pointer without crashing!
408 Daniel (3 April 2001)
409 - Puneet Pawaia pointed out two serious problems. Libcurl would attempt to
410 read bad memory during situations when an (ftp) connection attempt failed.
411 Also, the lib/Makefile.vc6 was corrected.
413 - More investigations in the Location: following code made me realize that
414 it was not clean enough to work transparantly with persistent and non-
415 persistent connections. I think I've fixed it now.
417 Daniel (29 March 2001)
418 - Georg Horn mailed me some corrections for the Curl::easy perl interface.
420 - Experimental ftps:// support added. It is basically FTP over SSL for the
421 control connection. It still makes all data transfers going over unencrypted
422 connections. Rainer Weikusat's ftpd-ssl server hack supports this and I used
423 that to verify the functionality.
425 Daniel (27 March 2001)
426 - Guenole Bescon discovered that if you set a CURLOPT_TIMEOUT and then tried
427 to get a file from a site and it fails, the SIGALRM would still be sent
428 after the timeout-time, quite inexpectedly!
430 - I added an ftp transfer example to docs/examples/ and I also wrote a tiny
431 example makefile that can be used as a start when building one of the
436 Daniel (26 March 2001)
437 - Mohamed Lrhazi reported problems with 7.6.1 and persistent HTTP/1.0
438 connections (when the server replied a Connection: Keep-Alive) and this
439 problem was not properly dealt with in 7.7 either. A patch was posted to the
440 curl-and-php mailing list.
442 Daniel (24 March 2001)
443 - Colin Watson reported about a problem and brought a patch that corrected it,
444 which was about the man page and lines starting with a single quote (') in a
445 way that gnroff doesn't like.
447 Daniel (23 March 2001)
448 - Peter Bray reported correctly that the root makefile used make instead of
449 $(MAKE) for the test target.
451 - Corrected the Curl::easy perl interface to use curl_easy_setopt() and not
452 curl_setopt() which was removed in 7.7!
454 - S. Moonesamy provided updates on three documents (MANUAL, INSTALL and FAQ).
456 - When following a Location:, libcurl would sometimes write to the URL string
457 in a way it shouldn't. As the pointer is passed-in to libcurl from an
458 application, we can't be allowed to write to it. The particular bug report
459 from 'nk' that brought this up was because he had a read-only URL that then
460 caused a libcurl crash!
462 - No longer reads HEAD responses longer than to the last header. Previously,
463 curl would read the full reply if the connection was a "close" one.
465 - libcurl did re-use connections way too much. Doing "curl
466 http://www.{microsoft,ibm}.com" would make it re-use the connection which
467 made the second request return very odd results.
469 Daniel (22 March 2001)
470 - Edin Kadribasic made me aware that curl should not re-send POST requests
471 when following 302-redirects. I made 302 work like 303 which means curl uses
472 GET in the following request(s).
474 - libcurl now reset the "followed-location" counter on each invoke of
475 curl_easy_perform() as it otherwise would sum up all redirects on the same
476 connection and thus could reach the maxredirs counter wrongly.
478 - Jim Drash suggested curl_escape() should not re-encode what already looks
479 like an encoded sequence and I think that's a fair suggestion.
483 Daniel (22 March 2001)
484 - The configure script now fails with an error message if gethostbyname_r() is
485 detected but it couldn't figure out how to invoke it (what amount of
486 arguments it is supposed to get). Reports from Andrés García made me aware
489 - Talking with Jim Drash made me finally put the curl_escape and curl_unescape
490 functions in the curl.h include file and write man pages for them. The
491 escape function was modified to use the same interface as the unescape one
494 - No bug reports at all on the latest betas. Release time coming up.
498 Daniel (19 March 2001)
499 - Georg Ottinger reported problems with using -C together with -L in the sense
500 that the -C info got lost when it was redirected. I could not repeat this
501 problem on the 7.7 branch why I leave this for the moment. Test case 39 was
502 added to do exactly this, and it seems to do right.
504 - Christian Robottom Reis reported how his 7.7 beta didn't successfully do
505 form posts as elegantly as 7.6.1 did. Indeed, this was a flaw in the header
506 engine, as HTTP 1.1 has introduced a new 100 "transient" return code for PUT
507 and POST operations that I need to add support for. Section 8.2.3 in RFC2616
508 has all the details. Seems to work now!
510 Daniel (16 March 2001)
511 - After having experienced another machine break-down, we're back.
513 - Georg Horn's perl interface Curl::easy is now included in the curl release
514 archive. The perl/ directory is now present. Please help me with docs,
515 examples and updates you think fit.
517 - Made a new php/ directory in the release archive and moved the PHP examples
518 into a subdirectory in there. Not much PHP info yet, but I plan to. Please
519 help me here as well!
521 - Made libcurl return error if a transfer is aborted in the middle of a
522 "chunk". It actually enables libcurl to discover premature transfer aborts
523 even if the Content-Length: size is unknown.
525 Daniel (15 March 2001)
526 - Added --connect-timeout to curl, which sets the new CURLOPT_CONNECTTIMEOUT
527 option in libcurl. It limits the time curl is allowed to spend in the
528 connection phase. This differs from -m/--max-time that limits the entire
529 file transfer operation. Requested by Larry Fahnoe and others.
531 I also updated the curl.1 and curl_easy_setopt.3 man pages and removed the
536 Daniel (14 March 2001)
537 - Made curl grok IPv6 with HTTP proxies and got everything to compile nicely
538 again when ENABLE_IPV6 is set.
540 I need to remake things in the test suite. I can't test the FTP parts with
541 curl built for IPv6 as it uses a different set of FTP commands then!
543 - I fell onto a bug report on php.net (posted by Lars Torben Wilson) that was
544 a report meant for our project. Anyway, it said the .netrc parsing didn't
545 work as supposed, and as I agreed with Lars, I made the netrc parser use
546 getpwuid() to figure out the home directory of the effective user and try
547 that netrc. It still uses the environment variable HOME for those that don't
548 have that function or if the user doesn't return valid pwd info.
550 - Edin Kadribaic posted a bug report where he got a crash when a fetch with
551 user+password in the URL followed a Location: to a second URL (absolute,
552 without name+password). This bug has been around for a long while and
553 crashes due to a read at address zero. Fixed now. Wrote test case 38, that
556 - Modified the test suite's httpserver slightly to append all client request
557 data to its log file so that the test script now better can verify a range
558 of requests and not only the last one, as it did previously.
560 - Updated the curl man page with --random-file and --egd-file details.
564 Daniel (14 March 2001)
565 - Björn Stenberg provided similar fixes as Jörn did and some additional patches
566 for non-SSL compiles.
568 - I increased the interface number for libcurl as I've removed the low level
569 functions from the interface. I also took this opportunity to rename the
570 Curl_strequal function to curl_strequal and Curl_strnequal to
571 curl_strnequal, as they're public libcurl functions (even if they're still
574 This will make older programs not capable of using the new libcurl with
575 just a drop-in replacement.
577 - Jörn Hartroth updated stuff for win32 compiles:
578 o config-win32.h was fixed for socklen_t
579 o lib/ssluse.c had a bad #endif placement
580 o lib/file.c was made to compile on win32 again
581 o lib/Makefile.m32 was updated with the new files
582 o lib/libcurl.def matches the current interface state
584 Daniel (13 March 2001)
585 - It only took an hour or so before Jörn Hartroth found a problem in the
586 chunked transfer-encoding. Given his fine example-site, I could easily spot
587 the problem and when I re-read the spec (the part I have pasted in the top
588 of the http_chunks.h file), I realized I had made my state-machine slightly
589 wrong and didn't expect/handle the trailing CRLF that comes after the data
590 in each chunk (and those extra two bytes sure feel wasted).
592 Had to modify test case 34 to match this as well.
596 Daniel (13 March 2001)
597 - Added the policy stuff to the curl_easy_setopt man page for the two supported
600 - Implemented some support for the CURLOPT_CLOSEPOLICY option. The policies
601 CURLCLOSEPOLICY_LEAST_RECENTLY_USED and CURLCLOSEPOLICY_OLDEST are now
602 supported, and the "least recently used" is used as default if no policy
605 Daniel (12 March 2001)
606 - Added CURLOPT_RANDOM_FILE and CURLOPT_EGDSOCKET to libcurl for seeding the
607 SSL random engine. The random seeding support was also brought to the curl
608 client with the new options --random-file <file> and --egd-file <file>. I
609 need some people to really test this to know they work as supposed. Remember
610 that libcurl now informs (if verbose is on) if the random seed is considered
611 weak (HTTPS connections).
613 - Made the chunked transfer-encoding engine detected bad formatted data length
614 and return error if so (we can't possibly extract sensible data if this is
615 the case). Added a test case that detects this. Number 36. Now there are 60
618 - Added 5 new libcurl options to curl/curl.h that can be used to control the
619 persistent connection support in libcurl. They're also documented (fairly
620 thoroughly) in the curl_easy_setopt.3 man page. Three of them are now
621 implemented, although not really tested at this point... Anyway, the new
622 implemented options are named CURLOPT_MAXCONNECTS, CURLOPT_FRESH_CONNECT,
623 CURLOPT_FORBID_REUSE. The ones still left to write code for are:
624 CURLOPT_CLOSEPOLICY and its related option CURLOPT_CLOSEFUNCTION.
626 - Made curl (the actual command line tool) use the new libcurl 7.7 persistent
627 connection support by re-using the same curl handle for every specified file
628 transfer and after some more test case tweaking we have 100% test case OK.
629 I made some test cases return HTTP/1.0 now to make sure that works as well.
631 - Had to add 'Connection: close' to the headers of a bunch of test cases so
632 that curl behaves "old-style" since the test http server doesn't do multiple
633 connections... Now I get 100% test case OK.
635 - The curl.haxx.se site, the main curl mailing list and my personal email are
636 all dead today due to power blackout in the area where the main servers are
639 - I've made persistance work over a squid HTTP proxy. I find it disturbing
640 that it uses headers that aren't present in any HTTP standard though
641 (Proxy-Connection:) and that makes me feel that I'm now on the edge of what
642 the standard actually defines. I need to get this code excercised on a lot
643 of different HTTP proxies before I feel safe.
645 Now I'm facing the problem with my test suite servers (both FTP and HTTP)
646 not supporting persistent connections and libcurl is doing them now. I have
647 to fix the test servers to get all the test cases do OK.
649 Daniel (8 March 2001)
650 - Guenole Bescon reported that libcurl did output errors to stderr even if
651 MUTE and NOPROGRESS was set. It turned out to be a bug and happens if
652 there's an error and no ERRORBUFFER is set. This is now corrected.
656 Daniel (8 March 2001)
657 - "Transfer-Encoding: chunked" is no longer any trouble for libcurl. I've
658 added two source files and I've run some test downloads that look fine.
660 - HTTP HEAD works too, even on 1.1 servers.
662 Daniel (5 March 2001)
663 - The current 57 test cases now pass OK. It would suggest that libcurl works
664 using the old-style with one connection per handle. The test suite doesn't
665 handle multiple connections yet so there are no test cases for this.
667 - I patched the telnet.c heavily to not use any global variables anymore. It
668 should make it a lot nicer library-wise.
670 - The file:// support was modified slightly to use the internal connect-first-
673 Daniel (4 March 2001)
678 Daniel (4 March 2001)
679 - Now, there's even a basic check that a re-used connection is still alive
680 before it is assumed so. A few first tests have proven that libcurl will
681 then re-connect instead of re-use the dead connection!
683 Daniel (2 March 2001)
684 - Now they work intermixed as well. Major coolness!
686 - More fiddling around, my 'tiny' client I have for testing purposes now has
687 proved to download both FTP and HTTP with persistent connections. They do
688 not work intermixed yet though.
690 Daniel (1 March 2001)
691 - Wilfredo Sanchez pointed out a minor spelling mistake in a man page and that
692 curl_slist_append() should take a const char * as second argument. It does
695 Daniel (22 February 2001)
696 - The persistent connections start to look good for HTTP. On a subsequent
697 request, it seems that libcurl now can pick an already existing connection
698 if a suitable one exists, or it opens a new one.
700 - Douglas R. Horner mailed me corrections to the curl_formparse() man page
703 Daniel (20 February 2001)
704 - Added the docs/examples/win32sockets.c file for our windows friends.
706 - Linus Nielsen Feltzing provided brand new TELNET functionality and
709 * Negotiation is now passive. Curl does not negotiate until the peer does.
710 * Possibility to set negotiation options on the command line, currently only
711 XDISPLOC, TTYPE and NEW_ENVIRON (called NEW_ENV).
712 * Now sends the USER environment variable if the -u switch is used.
713 * Use -t to set telnet options (Linus even updated the man page, awesome!)
715 - Haven't done this big changes to curl for a while. Moved around a lot of
716 struct fields and stuff to make multiple connections get connection specific
717 data in separate structs so that they can co-exist in a nice way. See the
718 mailing lists for discussions around how this is gonna be implemented. Docs
719 and more will follow.
721 Studied the HTTP RFC to find out better how persistent connections should
722 work. Seems cool enough.
724 Daniel (19 February 2001)
725 - Bob Schader brought me two files that help set up a MS VC++ libcurl project
726 easier. He also provided me with an up-to-date libcurl.def file.
728 - I moved a bunch of prototypes from the public <curl/curl.h> file to the
729 library private urldata.h. This is because of the upcoming changes. The
730 low level interface is no longer being planned to become reality.
732 Daniel (15 February 2001)
733 - CURLOPT_POST is not required anymore. Just setting the POST string with
734 CURLOPT_POSTFIELDS will switch on the HTTP POST. Most other things in
735 libcurl already works this way, i.e they require only the parameter to
736 switch on a feature so I think this works well with the rest. Setting a NULL
737 string switches off the POST again.
739 - Excellent suggestions from Rich Gray, Rick Jones, Johan Nilsson and Bjorn
740 Reese helped me define a way how to incorporate persistent connections into
741 libcurl in a very smooth way. If done right, no change may have to be made
742 to older programs and they will just start using persistent connections when
745 Daniel (13 February 2001)
746 - Changed the word 'timeouted' to 'timed out' in two different error messages.
747 Suggested by Larry Fahnoe.
751 Daniel (9 February 2001)
752 - Frank Reid and Cain Hopwood provided information and research around a HTTPS
753 PUT/upload problem we seem to have. No solution found yet.
755 Daniel (8 February 2001)
756 - An interesting discussion is how to specify an empty password without having
757 curl ask for it interactively? The current implmentation takes an empty
758 password as a request for a password prompt. However, I still want to
759 support a blank user field. Thus, today if you enter "-u :" (without user
760 and password) curl will prompt for the password. Tricky. How would you
761 specify you want the prompt otherwise?
763 - Made the netrc parse result possible to use for other protocols than FTP and
764 HTTP (such as the upcoming TELNET fixes).
766 - The previously mentioned "MSVC++ problems" turned out to be a non-issue.
768 - Added a HTTP file upload code example in the docs/examples/ section on
771 - Adjusted the FTP response fix slightly.
775 Daniel (7 February 2001)
776 - S. Moonesamy found a flaw in the response reading function for FTP that
777 could make libcurl not get out of the loop properly when it should, if
778 libcurl got -1 returned when reading the socket.
780 - I found a similar mistake in http.c when using a proxy and reading the
781 results from the proxy connection.
783 Daniel (6 February 2001)
784 - S. Moonesamy pointed out that the VC makefile in src/ needed the libpath set
785 for the debug build to work.
787 - Daniel Gehriger stepped in to assist with the VC++ stuff Robert Weaver
788 brought up yesterday.
790 Daniel (5 February 2001)
791 - Jun-ichiro itojun Hagino brought a big patch that brings IPv6-awareness to
792 a bunch of different areas within libcurl.
794 - Robert Weaver told me about the problems the MS VC++ 6.0 compiler has with
795 the 'static' keyword on a number of libcurl functions. I might need to add a
796 patch that redefines static when libcurl is compiled with that compiler.
797 How do I know when VC++ compiles, anyone?
799 Daniel (4 February 2001)
800 - curl_getinfo() was extended with two new options:
801 CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD. They
802 return the full assumed content length of the transfer in the given
803 direction. The CURLINFO_CONTENT_LENGTH_DOWNLOAD will be the Content-Length:
804 size of a HTTP download. Added descriptions to the man page as well. This
805 was done after discussions with Bob Schader.
807 Daniel (3 February 2001)
808 - Ingo Ralf Blum provided another fix that makes curl build under the more
809 recent cygwin installations. It seems they've changed the preset defines to
810 not include WIN32 anymore.
814 Daniel (31 January 2001)
815 - Curl_read() and curl_read() now return a ssize_t for the size, as it had to
816 be able to return -1. The telnet support crashed due to this and there was a
817 possibility to weird behaviour all over. Linus Nielsen Feltzing helped me
820 - Added a configure.in check for a working getaddrinfo() if IPv6 is requested.
821 I also made the configure script feature --enable-debug which sets a couple
822 of compiler options when used. It assumes gcc.
824 Daniel (30 January 2001)
825 - I finally took a stab at the long-term FIXME item I've had on myself, and
826 now libcurl will properly work when doing a HTTP range-request that follows
827 a Location:. Previously that would make libcurl fail saying that the server
828 doesn't seem to support range requests.
830 Daniel (29 January 2001)
831 - I added a test case for the HTTP PUT resume thing (test case 33).
835 Daniel (29 January 2001)
836 - Yet another Content-Range change. Ok now? Bob Schader checks from his end
837 and it works for him.
839 Daniel (27 January 2001)
840 - So the HTTP PUT resume fix wasn't good. There should appearantly be a
841 Content-Range header when resuming a PUT.
843 - I noticed I broke the download-check that verifies that a resumed HTTP
844 download is actually resumed. It got broke because my new 'httpreq' field
845 in the main curl struct. I should get slapped. I added a test case for
846 this now, so I won't be able to ruin this again without noticing.
848 - Added a test case for content-length verifying when downloading HTTP.
850 - Made the progress meter title say if the transfer is being transfered. It
851 makes the output slightly better for resumes.
853 - When dealing with Location: and HTTP return codes, libcurl will not attempt
854 to follow the spirit of RFC2616 better. It means that when POSTing to a
855 URL that is being following to a second place, the standard will judge on
856 what to do. All HTTP codes except 303 and 305 will cause curl to make a
857 second POST operation. 303 will make a GET and 305 is not yet supported.
859 I also wrote two test cases for this POST/GET/Location stuff.
863 Daniel (26 January 2001)
864 - Lots of mails back and forth with Bob Schader finally made me add a small
865 piece of code in the HTTP engine so that HTTP upload resume works. You can
866 now do an operation like 'curl -T file -C <offset> <URL>' and curl will PUT
867 the ending part of the file starting at given offet to the specified URL.
871 Daniel (25 January 2001)
872 - I took hold of Rick Jones' question why we don't use recv() and send() for
873 reading/writing to the sockets and I've now modified the sread() and
874 swrite() macros to use them instead. If nothing else, they could be tested
875 in the next beta-round coming right up.
877 - Jeff Morrow found a problem with libcurl's usage of SSL_read() and supplied
878 his research results in how to fix this. It turns out we have to invoke the
879 function several times in some cases. The same goes for the SSL_write().
881 I made some rather drastic changes all over libcurl to make all writes and
882 reads get done on one single place so that this repeated-attempts thing
883 would only have to be implemented at one point.
885 - Rick Jones spotted that the 'total time' counter really didn't measure the
886 total time very accurate on subsecond levels.
888 - Johan Nilsson pointed out the need to more clearly specify that the timeout
889 value you set for a download is for the *entire* download. There's currently
890 no option available that sets a timeout for the connection phase only.
892 Daniel (24 January 2001)
893 - Ingo Ralf Blum submitted a series of patches required to get curl to compile
894 properly with cygwin.
896 - Robert Weaver posted a fix for the win32 section of the curl_getenv() code
897 that corrected a potential memory leak.
899 - Added comments in a few files in a sudden attempt to make the sources more
900 easy to read and understand!
902 Daniel (23 January 2001)
903 - Added simple IPv6 detection in the configure script and made the version
904 string add 'ipv6' to the enable section in that case. ENABLE_IPV6 will be
905 set if curl is compiled with IPv6 support enabled.
907 - Added a parser for IPv6-style specified IP-addresses in a URL. Thus, when
908 IPv6 gets enabled soon, we can use URLs like '[0::1]:80'...
910 - Made the URL globbing in the client possible to fail silently if there's an
911 error in the globbing. It makes it almost intuitive, so when you don't
912 follow the syntax rules, globbing is simply switched off and the raw string
915 I still think we'll get problems with IPv6-style IP-addresses when we *want*
916 globbing on parts of the URL as the initial part of the URL will for sure
917 seriously confuse the globber.
919 Daniel (22 January 2001)
920 - Björn Stenberg supplied a progress meter patch that makes it look better even
921 during slow starts. Previously it made some silly assumptions...
923 - Added two FTP tests for -Q and -Q - stuff since it was being discussed on
924 the mailing list. Had to correct the ftpserver.pl too as it bugged slightly.
926 Daniel (19 January 2001)
927 - Made the Location: parsers deal with any-length URLs. Thus I removed the last
928 code that restricts the length of URLs that curl supports.
930 - Added a --globoff test case (#28) and it quickly identified a memory problem
931 in src/main.c that I took care of.
935 Daniel (17 January 2001)
936 - Made the two former files lib/download.c and lib/highlevel.c become the new
937 lib/transfer.c which makes more sense. I also did the rename from Transfer()
938 to Curl_Transfer() in the other source files that use the transfer function
939 in the spirit of using Curl_ prefix for library-scoped global symbols.
941 Daniel (11 January 2001)
942 - Added -g/--globoff that switches OFF the URL globbing and thus enables {}[]
943 letters to be part of the URL. Do note that RFC2396 section 2.4.3 explicitly
944 mention these letters to be escaped. This was posted as a feature request by
945 Jorge Gutierrez and as a bug by Terry.
947 - Short options to curl that requires parameters can now be specified without
948 having the option and its parameter space separated. -ofile works as good as
949 -o file. -m20 is equal to -m 20. Do note that this goes for single-letter
950 options only, verbose --long-style options still must be separated with
951 space from their parameters.
953 Daniel (8 January 2001)
954 - Francis Dagenais reported that the SCO compiler still fails when compiling
955 curl due to that getpass_r() prototype. I've now put it around #ifndef
956 HAVE_GETPASS_R in an attempt to please the SCO systems.
958 - Made some minor corrections to get the client to cleanup properly and I made
959 the separator work again when getting multiple globbed URLs to stdout.
961 - Worked with Loic Dachary to get the make dist and make distcheck work
962 correctly. The 'maketgz' script is now using the automake generated 'make
963 dist' when creating release archives. Loic successfully made 'make rpms'
964 automatically build RPMs!
966 Loic Dachary (6 January 2001)
967 - Automated generation of rpm packages, no need to be root.
969 - make distcheck generates a proper distribution (EXTRA_DIST
970 in all Makefile.am modified to match FILES).
972 Daniel (5 January 2001)
973 - Huge client-side hack: now multiple URLs are supported. Any number of URLs
974 can be specified on the command line, and they'll all be downloaded. There
975 must be a corresponding -o or -O for each URL or the data will be written to
976 stdout. This needs more testing, time to release a 7.6-pre package.
978 - The krb4 support was broken in the release. Fixed now.
980 - Huge internal symbol rename operation. All non-static but still lib-internal
981 symbols should now be prefixed with 'Curl_' to prevent collisions with other
982 libs. All public symbols should be prefixed with 'curl_' and the rest should
983 be static and thus invisible to the outside world. I updated the INTERNALS
984 document to say this as well.
988 Daniel (4 January 2001)
989 - As Kevin P Roth suggested, I've added text to the man page for every command
990 line option and what happens when you specify that option more than
991 once. That hasn't been exactly crystal clear before.
993 - Made the configure script possible to run from outside the source-tree. For
994 odd reasons I can't build curl properly outside though. It has to do with
995 curl's dependencies on libcurl...
997 - Cut off all older (dated 1999 and earlier) CHANGES entries from this file.
998 The older piece is named CHANGES.0 and is added to the CVS repository in
999 case anyone would need it.
1001 - I added another file 'CVS-INFO' to the CVS. It contains information about
1002 files in the CVS that aren't included in release archives and how to build
1003 curl when you get the sources off CVS.
1005 - Updated CONTRIBUTE and FAQ due to the new license.
1007 Daniel (3 January 2001)
1008 - Renamed README.libcurl to LIBCURL
1010 - Changed headers in all sources files to the new dual license concept of
1011 curl: use the MIT/X derivate license *or* MPL. The LEGAL file was updated
1012 accordingly and the MPL 1.1 and MIT/X derivate licenses are now part of the
