10 - I made ftps:// work. Added test case 400 to the release archive, as the
11 first ftps:// test case. Requires stunnel.
13 - Also made the test cases that runs ssl tests not run if libcurl isn't built
17 - Made the configure not add any extra -L LDFLAGS or -I CPPFLAGS unless they
18 are actually needed. Albert Chin's and Domenico Andreoli's suggestions
24 - Nicer configure-check for the OpenSSL headers, which then sets the proper
25 variable to have curl-config be good. (Albert Chin provided the fix)
27 - For systems that don't have theiw own 'strlcat()' libcurl provides its own.
28 It was now renamed to prevent collides with other libs. (After discussions
29 with Sterling Hughes and the implications this had on PHP builds.)
32 - Colm Buckley posted a detailed bug report on (the debianized) 7.7.3, that
33 turned out to be a problem with the debian-built 7.7.3-package that
34 contained files from the 7.7.2 release!
36 - I added the CURLE_ALREADY_COMPLETE again, but with a fake value, just to
37 make programs that use it, not fail when compiling against this version of
41 - Pawel A. Gajda fixed a problem with resumed transfers on re-used persistent
47 - Jun-ichiro itojun Hagino fixed FTP PORT for IPv6-enabled libcurl.
49 - Added the first HTTPS test to the test suite in the release archive.
52 - Jukka Pihl suggested that if (lib)curl is told to verify the peer's
53 certificate and the peer can't be verified, it should fail and return a
54 proper error code. I added a brand new error code named
55 CURLE_SSL_PEER_CERTIFICATE for this purpose.
58 - As was discussed with Frederic Lepied a while ago, I now made libcurl not
59 return error even though no data was transfered on upload/download resume
60 when the no transfer is needed. The CURLE_ALREADY_COMPLETE error was removed
61 from the header file to make any implemenator that uses that to be aware of
62 the fact that it can't be returned anymore!
64 - Improved general header-parsing to better allow white spaces and more.
66 - Rodney Simmons proved the fix I did yesterday was bad and I had to post
69 - Ingo Wilken patched away two redirect problems more!
72 - Cris Bailiff correctly noted that the space-after-header problem with
73 Location: is present on several other places in the libcurl sources.
75 - Ingo Wilken patched away a problem libcurl had when following Location:
76 headers with an extra space after the colon.
78 - Rodney Simmons found out that multiple FTP transfers did not treat relative
79 directories correctly.
82 - Getting an FTP file with CURLOPT_NOBODY set (or -I from the command line),
83 makes curl use the non-standard ftp command "SIZE". If it failed, libcurl
84 returned error. Starting now, it just don't output the file size instead.
87 - stunnel.pm was accidentally left out from the release archive, it is now
88 added (stunnel is needed to run the https-tests in the test suite)
91 - Corrected two minor compiler warnings due to the FILE * to void * conversion
92 that I missed at two places. Jörn Hartroth brought me patches. Sander Gates
93 filed a bug report on this.
98 - All callback functions now take 'void *' instead of 'FILE *'. This is made
99 this way to make it more obvious to people that anything can be passed to
100 them (by using the apropriate option). After discussions with Sterling
104 - Cris Bailiff fixed a chunked transfer encoding problem with persistent
105 connection that made libcurl fail if the persistent connection used mixed
106 chunked and non-chunked transfers.
108 - Cris Bailiff fixed a bad treatment of 304-replies, as they would not be
109 treated as content-length 0 replies but would cause a "hang" until the
110 server timed-out and closed the connection.
112 - Brad Burdick found a minor problem in the docs/examples/Makefile.am
114 Daniel (27 April 2001)
115 - Updated the INTERALS document again. It was lagging a bit. I think I made it
116 more easy to follow now as well.
118 - Brad Burdick found a problem with persistent connections when curl received
119 a "Content-Length: 0" header.
121 - Giuseppe D'Ambrosio was first out to report that TELNET doesn't work in curl
122 compiled/built on win32. It seems to work for unixes though!
124 - Dave Hamilton reported weird problems with CURL/PHP that I really can't
125 explain at the moment. I'm hoping on some help from the PHP crew.
127 Daniel (26 April 2001)
128 - I rewrote the FTP command response function. I had to do it to make ftps
129 work, as the OpenSSL read()-function didn't work the same way the normal
130 unix read() does, but it was also a huge performance boost. Previously the
131 function read one byte at a time, now it reads very large chunks, and it
132 makes a notable speed difference.
134 Daniel (25 April 2001)
135 - Connection re-use when not using a proxy didn't work properly for
136 non-default port numbers.
138 Daniel (24 April 2001)
139 - I've noticed that FTPS doesn't work. We attempt to use ssl even for the
140 data transfer, which causes the transfer to 'hang'... We need to fix this.
142 - Improved the test suite to use 'stunnel' to do HTTPS and FTPS testing on
143 the alredy written perl servers easily.
145 Daniel (23 April 2001)
146 - The OpenSSL version string recently modified didn't zero terminate one
147 of the generated strings properly, which could lead to a crash or simply
148 weird version string output!
152 Daniel (22 April 2001)
153 - Rosimildo da Silva updated the Makefiles for Borland/Windows.
155 - Eric Rautman pointed out a problem with persistent connections that would
156 lead to broken Host: headers in the second HTTP request.
158 Daniel (20 April 2001)
159 - Added man pages for the curl_strequal() and curl_mprintf() families. Wrote
160 a 'libcurl overview' man page.
162 - Spell-fixed some documents.
164 - S. Moonesamy corrected mistakes in the man page.
166 - Cris Bailiff fixed the curl_slists options in the perl interface, present
167 separately in the Curl::easy 1.1.4 package.
169 Daniel (19 April 2001)
170 - Linus Nielsen Feltzing removed the decimals from the size variables in the
171 --write-out output. We hardly ever get fraction of bytes! :-)
175 Daniel (19 April 2001)
177 - Albert Chin provided a configure patch for the AC_SYS_LARGEFILE macro.
179 Daniel (18 April 2001)
180 - Input from Michael Mealling made me add --feature to curl-config. It
181 displays a list of features that have been built-in in the current
182 libcurl. The currently available features that can be listed are: SSL, KRB4
185 - I committed Cris and Georg's perl interface work. They've got callbacks
186 working and options that receives those slist pointers.
188 - Puneet Pawaia detected a problem with resumed downloads that use persistent
189 connections and I made a rather large writeup to correct this. It is
190 important that all session-data is stored in the connectdata struct and not
191 in the main struct as this previously did.
193 Daniel (17 April 2001)
194 - Frederic Lepied fixed a ftp resumed download problem and introduced a new
195 error code that lets applications be able to detect when a resumed download
196 actually didn't download anything since the whole file is already present.
197 Should this return OK instead?
199 - I added 'curl-config.in' to the root dir and configure script. Now, a
200 curl-config script is made when curl is built. The script can be used to
201 figure out compile time options used when libcurl was built, which in turn
202 should be options YOU should use to build applications that use libcurl.
204 This *-config style is not a new idea, but something that has been used
205 successfully in other (library based) projects.
207 - Phil Karn pointed out that libcurl wrongly did not always use GMT time zone
208 for the If-Modified-Since style headers.
210 - Georg Schwarz pointed out an extra needed #include file needed in src/main.c
211 for curl to build on Ultrix.
213 Daniel (11 April 2001)
214 - Cris Bailiff pointed out two problems that I corrected. First, libcurl's use
215 of the environment variable HTTP_PROXY in uppercase may become a security
216 hazard when people use libcurl in a server/cgi situation where the server
217 sets the HTTP_*-variables according to incoming headers in the HTTP
218 request. Thus, a "Proxy:"-header would set that environment variable!
220 Then, invoking curl_easy_perform() without having an URL set caused a crash.
222 - S. Moonesamy brought a patch that make curl use non-blocking connects on
223 windows when connection timeout is set, as it allows windows users to set
226 - Hirotaka Matsuyuki wrote a Ruby interface to libcurl!
228 - Cris Bailiff, Forrest Cahoon and Georg Horn work on the Perl interface.
230 - I've written a first shot at a Java interface to libcurl. Many thanks to
231 Daniel Marell for tirelessly answering to all my basic Java questions. It
232 works, but it is still very basic.
234 Daniel (10 April 2001)
235 - The progress display could get silly when doing multiple file transfers, as
236 it wasn't properly reset between transfers!
238 - Discussions with Cris Bailiff who writes a Perl interface to libcurl, made
239 me add CURLOPT_HEADERFUNCTION. It can be used to set a separate callback
240 function for writing headers. Previously you could only set a different FILE
241 * when headers are written from within libcurl.
243 Daniel (7 April 2001)
244 - Andrés García fixed a problem in curl_escape() and pointed out a flaw in
245 the curl_easy_setopt man page.
247 Daniel (6 April 2001)
248 - Adjusted the version code to properly display OpenSSL 0.9.6a. They sure
249 change their version define format often...
251 - curl_formfree() now accepts a NULL pointer without crashing!
255 Daniel (3 April 2001)
256 - Puneet Pawaia pointed out two serious problems. Libcurl would attempt to
257 read bad memory during situations when an (ftp) connection attempt failed.
258 Also, the lib/Makefile.vc6 was corrected.
260 - More investigations in the Location: following code made me realize that
261 it was not clean enough to work transparantly with persistent and non-
262 persistent connections. I think I've fixed it now.
264 Daniel (29 March 2001)
265 - Georg Horn mailed me some corrections for the Curl::easy perl interface.
267 - Experimental ftps:// support added. It is basically FTP over SSL for the
268 control connection. It still makes all data transfers going over unencrypted
269 connections. Rainer Weikusat's ftpd-ssl server hack supports this and I used
270 that to verify the functionality.
272 Daniel (27 March 2001)
273 - Guenole Bescon discovered that if you set a CURLOPT_TIMEOUT and then tried
274 to get a file from a site and it fails, the SIGALRM would still be sent
275 after the timeout-time, quite inexpectedly!
277 - I added an ftp transfer example to docs/examples/ and I also wrote a tiny
278 example makefile that can be used as a start when building one of the
283 Daniel (26 March 2001)
284 - Mohamed Lrhazi reported problems with 7.6.1 and persistent HTTP/1.0
285 connections (when the server replied a Connection: Keep-Alive) and this
286 problem was not properly dealt with in 7.7 either. A patch was posted to the
287 curl-and-php mailing list.
289 Daniel (24 March 2001)
290 - Colin Watson reported about a problem and brought a patch that corrected it,
291 which was about the man page and lines starting with a single quote (') in a
292 way that gnroff doesn't like.
294 Daniel (23 March 2001)
295 - Peter Bray reported correctly that the root makefile used make instead of
296 $(MAKE) for the test target.
298 - Corrected the Curl::easy perl interface to use curl_easy_setopt() and not
299 curl_setopt() which was removed in 7.7!
301 - S. Moonesamy provided updates on three documents (MANUAL, INSTALL and FAQ).
303 - When following a Location:, libcurl would sometimes write to the URL string
304 in a way it shouldn't. As the pointer is passed-in to libcurl from an
305 application, we can't be allowed to write to it. The particular bug report
306 from 'nk' that brought this up was because he had a read-only URL that then
307 caused a libcurl crash!
309 - No longer reads HEAD responses longer than to the last header. Previously,
310 curl would read the full reply if the connection was a "close" one.
312 - libcurl did re-use connections way too much. Doing "curl
313 http://www.{microsoft,ibm}.com" would make it re-use the connection which
314 made the second request return very odd results.
316 Daniel (22 March 2001)
317 - Edin Kadribasic made me aware that curl should not re-send POST requests
318 when following 302-redirects. I made 302 work like 303 which means curl uses
319 GET in the following request(s).
321 - libcurl now reset the "followed-location" counter on each invoke of
322 curl_easy_perform() as it otherwise would sum up all redirects on the same
323 connection and thus could reach the maxredirs counter wrongly.
325 - Jim Drash suggested curl_escape() should not re-encode what already looks
326 like an encoded sequence and I think that's a fair suggestion.
330 Daniel (22 March 2001)
331 - The configure script now fails with an error message if gethostbyname_r() is
332 detected but it couldn't figure out how to invoke it (what amount of
333 arguments it is supposed to get). Reports from Andrés García made me aware
336 - Talking with Jim Drash made me finally put the curl_escape and curl_unescape
337 functions in the curl.h include file and write man pages for them. The
338 escape function was modified to use the same interface as the unescape one
341 - No bug reports at all on the latest betas. Release time coming up.
345 Daniel (19 March 2001)
346 - Georg Ottinger reported problems with using -C together with -L in the sense
347 that the -C info got lost when it was redirected. I could not repeat this
348 problem on the 7.7 branch why I leave this for the moment. Test case 39 was
349 added to do exactly this, and it seems to do right.
351 - Christian Robottom Reis reported how his 7.7 beta didn't successfully do
352 form posts as elegantly as 7.6.1 did. Indeed, this was a flaw in the header
353 engine, as HTTP 1.1 has introduced a new 100 "transient" return code for PUT
354 and POST operations that I need to add support for. Section 8.2.3 in RFC2616
355 has all the details. Seems to work now!
357 Daniel (16 March 2001)
358 - After having experienced another machine break-down, we're back.
360 - Georg Horn's perl interface Curl::easy is now included in the curl release
361 archive. The perl/ directory is now present. Please help me with docs,
362 examples and updates you think fit.
364 - Made a new php/ directory in the release archive and moved the PHP examples
365 into a subdirectory in there. Not much PHP info yet, but I plan to. Please
366 help me here as well!
368 - Made libcurl return error if a transfer is aborted in the middle of a
369 "chunk". It actually enables libcurl to discover premature transfer aborts
370 even if the Content-Length: size is unknown.
372 Daniel (15 March 2001)
373 - Added --connect-timeout to curl, which sets the new CURLOPT_CONNECTTIMEOUT
374 option in libcurl. It limits the time curl is allowed to spend in the
375 connection phase. This differs from -m/--max-time that limits the entire
376 file transfer operation. Requested by Larry Fahnoe and others.
378 I also updated the curl.1 and curl_easy_setopt.3 man pages and removed the
383 Daniel (14 March 2001)
384 - Made curl grok IPv6 with HTTP proxies and got everything to compile nicely
385 again when ENABLE_IPV6 is set.
387 I need to remake things in the test suite. I can't test the FTP parts with
388 curl built for IPv6 as it uses a different set of FTP commands then!
390 - I fell onto a bug report on php.net (posted by Lars Torben Wilson) that was
391 a report meant for our project. Anyway, it said the .netrc parsing didn't
392 work as supposed, and as I agreed with Lars, I made the netrc parser use
393 getpwuid() to figure out the home directory of the effective user and try
394 that netrc. It still uses the environment variable HOME for those that don't
395 have that function or if the user doesn't return valid pwd info.
397 - Edin Kadribaic posted a bug report where he got a crash when a fetch with
398 user+password in the URL followed a Location: to a second URL (absolute,
399 without name+password). This bug has been around for a long while and
400 crashes due to a read at address zero. Fixed now. Wrote test case 38, that
403 - Modified the test suite's httpserver slightly to append all client request
404 data to its log file so that the test script now better can verify a range
405 of requests and not only the last one, as it did previously.
407 - Updated the curl man page with --random-file and --egd-file details.
411 Daniel (14 March 2001)
412 - Björn Stenberg provided similar fixes as Jörn did and some additional patches
413 for non-SSL compiles.
415 - I increased the interface number for libcurl as I've removed the low level
416 functions from the interface. I also took this opportunity to rename the
417 Curl_strequal function to curl_strequal and Curl_strnequal to
418 curl_strnequal, as they're public libcurl functions (even if they're still
421 This will make older programs not capable of using the new libcurl with
422 just a drop-in replacement.
424 - Jörn Hartroth updated stuff for win32 compiles:
425 o config-win32.h was fixed for socklen_t
426 o lib/ssluse.c had a bad #endif placement
427 o lib/file.c was made to compile on win32 again
428 o lib/Makefile.m32 was updated with the new files
429 o lib/libcurl.def matches the current interface state
431 Daniel (13 March 2001)
432 - It only took an hour or so before Jörn Hartroth found a problem in the
433 chunked transfer-encoding. Given his fine example-site, I could easily spot
434 the problem and when I re-read the spec (the part I have pasted in the top
435 of the http_chunks.h file), I realized I had made my state-machine slightly
436 wrong and didn't expect/handle the trailing CRLF that comes after the data
437 in each chunk (and those extra two bytes sure feel wasted).
439 Had to modify test case 34 to match this as well.
443 Daniel (13 March 2001)
444 - Added the policy stuff to the curl_easy_setopt man page for the two supported
447 - Implemented some support for the CURLOPT_CLOSEPOLICY option. The policies
448 CURLCLOSEPOLICY_LEAST_RECENTLY_USED and CURLCLOSEPOLICY_OLDEST are now
449 supported, and the "least recently used" is used as default if no policy
452 Daniel (12 March 2001)
453 - Added CURLOPT_RANDOM_FILE and CURLOPT_EGDSOCKET to libcurl for seeding the
454 SSL random engine. The random seeding support was also brought to the curl
455 client with the new options --random-file <file> and --egd-file <file>. I
456 need some people to really test this to know they work as supposed. Remember
457 that libcurl now informs (if verbose is on) if the random seed is considered
458 weak (HTTPS connections).
460 - Made the chunked transfer-encoding engine detected bad formatted data length
461 and return error if so (we can't possibly extract sensible data if this is
462 the case). Added a test case that detects this. Number 36. Now there are 60
465 - Added 5 new libcurl options to curl/curl.h that can be used to control the
466 persistent connection support in libcurl. They're also documented (fairly
467 thoroughly) in the curl_easy_setopt.3 man page. Three of them are now
468 implemented, although not really tested at this point... Anyway, the new
469 implemented options are named CURLOPT_MAXCONNECTS, CURLOPT_FRESH_CONNECT,
470 CURLOPT_FORBID_REUSE. The ones still left to write code for are:
471 CURLOPT_CLOSEPOLICY and its related option CURLOPT_CLOSEFUNCTION.
473 - Made curl (the actual command line tool) use the new libcurl 7.7 persistent
474 connection support by re-using the same curl handle for every specified file
475 transfer and after some more test case tweaking we have 100% test case OK.
476 I made some test cases return HTTP/1.0 now to make sure that works as well.
478 - Had to add 'Connection: close' to the headers of a bunch of test cases so
479 that curl behaves "old-style" since the test http server doesn't do multiple
480 connections... Now I get 100% test case OK.
482 - The curl.haxx.se site, the main curl mailing list and my personal email are
483 all dead today due to power blackout in the area where the main servers are
486 - I've made persistance work over a squid HTTP proxy. I find it disturbing
487 that it uses headers that aren't present in any HTTP standard though
488 (Proxy-Connection:) and that makes me feel that I'm now on the edge of what
489 the standard actually defines. I need to get this code excercised on a lot
490 of different HTTP proxies before I feel safe.
492 Now I'm facing the problem with my test suite servers (both FTP and HTTP)
493 not supporting persistent connections and libcurl is doing them now. I have
494 to fix the test servers to get all the test cases do OK.
496 Daniel (8 March 2001)
497 - Guenole Bescon reported that libcurl did output errors to stderr even if
498 MUTE and NOPROGRESS was set. It turned out to be a bug and happens if
499 there's an error and no ERRORBUFFER is set. This is now corrected.
503 Daniel (8 March 2001)
504 - "Transfer-Encoding: chunked" is no longer any trouble for libcurl. I've
505 added two source files and I've run some test downloads that look fine.
507 - HTTP HEAD works too, even on 1.1 servers.
509 Daniel (5 March 2001)
510 - The current 57 test cases now pass OK. It would suggest that libcurl works
511 using the old-style with one connection per handle. The test suite doesn't
512 handle multiple connections yet so there are no test cases for this.
514 - I patched the telnet.c heavily to not use any global variables anymore. It
515 should make it a lot nicer library-wise.
517 - The file:// support was modified slightly to use the internal connect-first-
520 Daniel (4 March 2001)
525 Daniel (4 March 2001)
526 - Now, there's even a basic check that a re-used connection is still alive
527 before it is assumed so. A few first tests have proven that libcurl will
528 then re-connect instead of re-use the dead connection!
530 Daniel (2 March 2001)
531 - Now they work intermixed as well. Major coolness!
533 - More fiddling around, my 'tiny' client I have for testing purposes now has
534 proved to download both FTP and HTTP with persistent connections. They do
535 not work intermixed yet though.
537 Daniel (1 March 2001)
538 - Wilfredo Sanchez pointed out a minor spelling mistake in a man page and that
539 curl_slist_append() should take a const char * as second argument. It does
542 Daniel (22 February 2001)
543 - The persistent connections start to look good for HTTP. On a subsequent
544 request, it seems that libcurl now can pick an already existing connection
545 if a suitable one exists, or it opens a new one.
547 - Douglas R. Horner mailed me corrections to the curl_formparse() man page
550 Daniel (20 February 2001)
551 - Added the docs/examples/win32sockets.c file for our windows friends.
553 - Linus Nielsen Feltzing provided brand new TELNET functionality and
556 * Negotiation is now passive. Curl does not negotiate until the peer does.
557 * Possibility to set negotiation options on the command line, currently only
558 XDISPLOC, TTYPE and NEW_ENVIRON (called NEW_ENV).
559 * Now sends the USER environment variable if the -u switch is used.
560 * Use -t to set telnet options (Linus even updated the man page, awesome!)
562 - Haven't done this big changes to curl for a while. Moved around a lot of
563 struct fields and stuff to make multiple connections get connection specific
564 data in separate structs so that they can co-exist in a nice way. See the
565 mailing lists for discussions around how this is gonna be implemented. Docs
566 and more will follow.
568 Studied the HTTP RFC to find out better how persistent connections should
569 work. Seems cool enough.
571 Daniel (19 February 2001)
572 - Bob Schader brought me two files that help set up a MS VC++ libcurl project
573 easier. He also provided me with an up-to-date libcurl.def file.
575 - I moved a bunch of prototypes from the public <curl/curl.h> file to the
576 library private urldata.h. This is because of the upcoming changes. The
577 low level interface is no longer being planned to become reality.
579 Daniel (15 February 2001)
580 - CURLOPT_POST is not required anymore. Just setting the POST string with
581 CURLOPT_POSTFIELDS will switch on the HTTP POST. Most other things in
582 libcurl already works this way, i.e they require only the parameter to
583 switch on a feature so I think this works well with the rest. Setting a NULL
584 string switches off the POST again.
586 - Excellent suggestions from Rich Gray, Rick Jones, Johan Nilsson and Bjorn
587 Reese helped me define a way how to incorporate persistent connections into
588 libcurl in a very smooth way. If done right, no change may have to be made
589 to older programs and they will just start using persistent connections when
592 Daniel (13 February 2001)
593 - Changed the word 'timeouted' to 'timed out' in two different error messages.
594 Suggested by Larry Fahnoe.
598 Daniel (9 February 2001)
599 - Frank Reid and Cain Hopwood provided information and research around a HTTPS
600 PUT/upload problem we seem to have. No solution found yet.
602 Daniel (8 February 2001)
603 - An interesting discussion is how to specify an empty password without having
604 curl ask for it interactively? The current implmentation takes an empty
605 password as a request for a password prompt. However, I still want to
606 support a blank user field. Thus, today if you enter "-u :" (without user
607 and password) curl will prompt for the password. Tricky. How would you
608 specify you want the prompt otherwise?
610 - Made the netrc parse result possible to use for other protocols than FTP and
611 HTTP (such as the upcoming TELNET fixes).
613 - The previously mentioned "MSVC++ problems" turned out to be a non-issue.
615 - Added a HTTP file upload code example in the docs/examples/ section on
618 - Adjusted the FTP response fix slightly.
622 Daniel (7 February 2001)
623 - S. Moonesamy found a flaw in the response reading function for FTP that
624 could make libcurl not get out of the loop properly when it should, if
625 libcurl got -1 returned when reading the socket.
627 - I found a similar mistake in http.c when using a proxy and reading the
628 results from the proxy connection.
630 Daniel (6 February 2001)
631 - S. Moonesamy pointed out that the VC makefile in src/ needed the libpath set
632 for the debug build to work.
634 - Daniel Gehriger stepped in to assist with the VC++ stuff Robert Weaver
635 brought up yesterday.
637 Daniel (5 February 2001)
638 - Jun-ichiro itojun Hagino brought a big patch that brings IPv6-awareness to
639 a bunch of different areas within libcurl.
641 - Robert Weaver told me about the problems the MS VC++ 6.0 compiler has with
642 the 'static' keyword on a number of libcurl functions. I might need to add a
643 patch that redefines static when libcurl is compiled with that compiler.
644 How do I know when VC++ compiles, anyone?
646 Daniel (4 February 2001)
647 - curl_getinfo() was extended with two new options:
648 CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD. They
649 return the full assumed content length of the transfer in the given
650 direction. The CURLINFO_CONTENT_LENGTH_DOWNLOAD will be the Content-Length:
651 size of a HTTP download. Added descriptions to the man page as well. This
652 was done after discussions with Bob Schader.
654 Daniel (3 February 2001)
655 - Ingo Ralf Blum provided another fix that makes curl build under the more
656 recent cygwin installations. It seems they've changed the preset defines to
657 not include WIN32 anymore.
661 Daniel (31 January 2001)
662 - Curl_read() and curl_read() now return a ssize_t for the size, as it had to
663 be able to return -1. The telnet support crashed due to this and there was a
664 possibility to weird behaviour all over. Linus Nielsen Feltzing helped me
667 - Added a configure.in check for a working getaddrinfo() if IPv6 is requested.
668 I also made the configure script feature --enable-debug which sets a couple
669 of compiler options when used. It assumes gcc.
671 Daniel (30 January 2001)
672 - I finally took a stab at the long-term FIXME item I've had on myself, and
673 now libcurl will properly work when doing a HTTP range-request that follows
674 a Location:. Previously that would make libcurl fail saying that the server
675 doesn't seem to support range requests.
677 Daniel (29 January 2001)
678 - I added a test case for the HTTP PUT resume thing (test case 33).
682 Daniel (29 January 2001)
683 - Yet another Content-Range change. Ok now? Bob Schader checks from his end
684 and it works for him.
686 Daniel (27 January 2001)
687 - So the HTTP PUT resume fix wasn't good. There should appearantly be a
688 Content-Range header when resuming a PUT.
690 - I noticed I broke the download-check that verifies that a resumed HTTP
691 download is actually resumed. It got broke because my new 'httpreq' field
692 in the main curl struct. I should get slapped. I added a test case for
693 this now, so I won't be able to ruin this again without noticing.
695 - Added a test case for content-length verifying when downloading HTTP.
697 - Made the progress meter title say if the transfer is being transfered. It
698 makes the output slightly better for resumes.
700 - When dealing with Location: and HTTP return codes, libcurl will not attempt
701 to follow the spirit of RFC2616 better. It means that when POSTing to a
702 URL that is being following to a second place, the standard will judge on
703 what to do. All HTTP codes except 303 and 305 will cause curl to make a
704 second POST operation. 303 will make a GET and 305 is not yet supported.
706 I also wrote two test cases for this POST/GET/Location stuff.
710 Daniel (26 January 2001)
711 - Lots of mails back and forth with Bob Schader finally made me add a small
712 piece of code in the HTTP engine so that HTTP upload resume works. You can
713 now do an operation like 'curl -T file -C <offset> <URL>' and curl will PUT
714 the ending part of the file starting at given offet to the specified URL.
718 Daniel (25 January 2001)
719 - I took hold of Rick Jones' question why we don't use recv() and send() for
720 reading/writing to the sockets and I've now modified the sread() and
721 swrite() macros to use them instead. If nothing else, they could be tested
722 in the next beta-round coming right up.
724 - Jeff Morrow found a problem with libcurl's usage of SSL_read() and supplied
725 his research results in how to fix this. It turns out we have to invoke the
726 function several times in some cases. The same goes for the SSL_write().
728 I made some rather drastic changes all over libcurl to make all writes and
729 reads get done on one single place so that this repeated-attempts thing
730 would only have to be implemented at one point.
732 - Rick Jones spotted that the 'total time' counter really didn't measure the
733 total time very accurate on subsecond levels.
735 - Johan Nilsson pointed out the need to more clearly specify that the timeout
736 value you set for a download is for the *entire* download. There's currently
737 no option available that sets a timeout for the connection phase only.
739 Daniel (24 January 2001)
740 - Ingo Ralf Blum submitted a series of patches required to get curl to compile
741 properly with cygwin.
743 - Robert Weaver posted a fix for the win32 section of the curl_getenv() code
744 that corrected a potential memory leak.
746 - Added comments in a few files in a sudden attempt to make the sources more
747 easy to read and understand!
749 Daniel (23 January 2001)
750 - Added simple IPv6 detection in the configure script and made the version
751 string add 'ipv6' to the enable section in that case. ENABLE_IPV6 will be
752 set if curl is compiled with IPv6 support enabled.
754 - Added a parser for IPv6-style specified IP-addresses in a URL. Thus, when
755 IPv6 gets enabled soon, we can use URLs like '[0::1]:80'...
757 - Made the URL globbing in the client possible to fail silently if there's an
758 error in the globbing. It makes it almost intuitive, so when you don't
759 follow the syntax rules, globbing is simply switched off and the raw string
762 I still think we'll get problems with IPv6-style IP-addresses when we *want*
763 globbing on parts of the URL as the initial part of the URL will for sure
764 seriously confuse the globber.
766 Daniel (22 January 2001)
767 - Björn Stenberg supplied a progress meter patch that makes it look better even
768 during slow starts. Previously it made some silly assumptions...
770 - Added two FTP tests for -Q and -Q - stuff since it was being discussed on
771 the mailing list. Had to correct the ftpserver.pl too as it bugged slightly.
773 Daniel (19 January 2001)
774 - Made the Location: parsers deal with any-length URLs. Thus I removed the last
775 code that restricts the length of URLs that curl supports.
777 - Added a --globoff test case (#28) and it quickly identified a memory problem
778 in src/main.c that I took care of.
782 Daniel (17 January 2001)
783 - Made the two former files lib/download.c and lib/highlevel.c become the new
784 lib/transfer.c which makes more sense. I also did the rename from Transfer()
785 to Curl_Transfer() in the other source files that use the transfer function
786 in the spirit of using Curl_ prefix for library-scoped global symbols.
788 Daniel (11 January 2001)
789 - Added -g/--globoff that switches OFF the URL globbing and thus enables {}[]
790 letters to be part of the URL. Do note that RFC2396 section 2.4.3 explicitly
791 mention these letters to be escaped. This was posted as a feature request by
792 Jorge Gutierrez and as a bug by Terry.
794 - Short options to curl that requires parameters can now be specified without
795 having the option and its parameter space separated. -ofile works as good as
796 -o file. -m20 is equal to -m 20. Do note that this goes for single-letter
797 options only, verbose --long-style options still must be separated with
798 space from their parameters.
800 Daniel (8 January 2001)
801 - Francis Dagenais reported that the SCO compiler still fails when compiling
802 curl due to that getpass_r() prototype. I've now put it around #ifndef
803 HAVE_GETPASS_R in an attempt to please the SCO systems.
805 - Made some minor corrections to get the client to cleanup properly and I made
806 the separator work again when getting multiple globbed URLs to stdout.
808 - Worked with Loic Dachary to get the make dist and make distcheck work
809 correctly. The 'maketgz' script is now using the automake generated 'make
810 dist' when creating release archives. Loic successfully made 'make rpms'
811 automatically build RPMs!
813 Loic Dachary (6 January 2001)
814 - Automated generation of rpm packages, no need to be root.
816 - make distcheck generates a proper distribution (EXTRA_DIST
817 in all Makefile.am modified to match FILES).
819 Daniel (5 January 2001)
820 - Huge client-side hack: now multiple URLs are supported. Any number of URLs
821 can be specified on the command line, and they'll all be downloaded. There
822 must be a corresponding -o or -O for each URL or the data will be written to
823 stdout. This needs more testing, time to release a 7.6-pre package.
825 - The krb4 support was broken in the release. Fixed now.
827 - Huge internal symbol rename operation. All non-static but still lib-internal
828 symbols should now be prefixed with 'Curl_' to prevent collisions with other
829 libs. All public symbols should be prefixed with 'curl_' and the rest should
830 be static and thus invisible to the outside world. I updated the INTERNALS
831 document to say this as well.
835 Daniel (4 January 2001)
836 - As Kevin P Roth suggested, I've added text to the man page for every command
837 line option and what happens when you specify that option more than
838 once. That hasn't been exactly crystal clear before.
840 - Made the configure script possible to run from outside the source-tree. For
841 odd reasons I can't build curl properly outside though. It has to do with
842 curl's dependencies on libcurl...
844 - Cut off all older (dated 1999 and earlier) CHANGES entries from this file.
845 The older piece is named CHANGES.0 and is added to the CVS repository in
846 case anyone would need it.
848 - I added another file 'CVS-INFO' to the CVS. It contains information about
849 files in the CVS that aren't included in release archives and how to build
850 curl when you get the sources off CVS.
852 - Updated CONTRIBUTE and FAQ due to the new license.
854 Daniel (3 January 2001)
855 - Renamed README.libcurl to LIBCURL
857 - Changed headers in all sources files to the new dual license concept of
858 curl: use the MIT/X derivate license *or* MPL. The LEGAL file was updated
859 accordingly and the MPL 1.1 and MIT/X derivate licenses are now part of the
862 Daniel (30 December 2000)
863 - Made all FTP commands get sent with the trailing CRLF in one single write()
864 as splitting them up seems to confuse at least some firewalls (FW-1 being
867 Daniel (19 December 2000)
868 - Added file desrciptor and FILE handle leak detection to the memdebug system
869 and thus I found and removed a file descriptor leakage in the ftp parts
870 that happened when you did PORTed downloads.
872 - Added an include <stdio.h> in <curl/curl.h> since it uses FILE *.
874 Daniel (12 December 2000)
875 - Multiple URL downloads with -O was still bugging. Not anymore I think or
876 hope, or at least I've tried... :-O
878 - Francois Petitjean fixed another -O problem
882 Daniel (11 December 2000)
883 - Cleaned up a few of the makefiles to use unix-style newlines only. As Kevin
884 P Roth found out, at least one CVS client behaved wrongly when it found
885 different newline conventions within the same file.
887 - Albert Chin-A-Young corrected the LDFLAGS use in the configure script for
890 Daniel (6 December 2000)
891 - Massimo Squillace correctly described how libcurl could use session ids when
892 doing SSL connections.
894 - James Griffiths found out that curl would crash if the file you specify with
895 -o is shorter than the URL! This took some hours to fully hunt down, but it
898 Daniel (5 December 2000)
899 - Jaepil Kim sent us makefiles that build curl using the free windows borland
900 compiler. The root makefile now accepts 'make borland' to build curl with
903 - Stefan Radman pointed out that the test makefiles didn't use the PERL
904 variable that the configure scripts figure out. Actually, you still need
905 perl in the path for the test suite to run ok.
907 - Rich Gray found numerous portability problems:
908 * The SCO compiler got an error on the getpass_r() prototype in getpass.h
909 since the curl one differed from the SCO one
910 * The HPUX compiler got an error because of how curl did the sigaction
911 stuff and used a define HPUX doesn't have (or need).
912 * A few more problems remain to be researched.
914 - Paul Harrington experienced a core dump using https. Not much details yet.
916 Daniel (4 December 2000)
917 - Jörn Hartroth fixed a problem with multiple URLs and -o/-O.
921 Daniel (1 December 2000)
922 - Craig Davison gave us his updates on the VC++ makefiles, so now curl should
923 build fine with the Microsoft compiler on windows too.
925 - Fixed the libcurl versioning so that we don't ruin old programs when
926 releasing new shared library interfaces.
928 Daniel (30 November 2000)
929 - Renamed docs/README.curl to docs/MANUAL to better reflect what the document
932 Daniel (29 November 2000)
933 - I removed a bunch of '#if 0' sections from the code. They only make things
934 harder to follow. After all, we do have all older versions in the CVS.
938 Daniel (28 November 2000)
939 - I filled in more error codes in the man page error code list that had been
942 - James Griffiths mailed me a fine patch that introduces the CURLOPT_MAXREDIRS
943 libcurl option. When used, it'll prevent location following more than the
944 set number of times. It is useful to break out of endless redirect-loops.
946 Daniel (27 November 2000)
947 - Added two test cases for file://.
949 Daniel (22 November 2000)
950 - Added the libcurl CURLOPT_FILETIME setopt, when set it tries to get the
951 modified time of the remote document. This is a special option since it
952 involves an extra set of commands on FTP servers. (Using the MDTM command
953 which is not in the RFC959)
955 curl_easy_getinfo() got a corresponding CURLINFO_FILETIME to get the time
956 after a transfer. It'll return a zero if CURLOPT_FILETIME wasn't used or if
957 the time wasn't possible to get.
959 --head/-I used on a FTP server will now present a 'Last-Modified:' header
960 if curl could get the time of the specified file.
962 - Added the option '--cacert [file]' to curl, which allows a specified PEM
963 file to be used to verify the peer's certificate when doing HTTPS
964 connections. This has been requested, rather recently by Hulka Bohuslav but
965 others have asked for it before as well.
967 Daniel (21 November 2000)
968 - Numerous fixes the test suite has brought into the daylight:
970 * curl_unescape() could return a too long string
971 * on ftp transfer failures, there could be memory leaks
972 * ftp CWD could use bad directory names
973 * memdebug now uses the mprintf() routines for better portability
974 * free(NULL) removed when doing resumed transfers
976 - Added a bunch of test cases for FTP.
978 - General cleanups to make less warnings with gcc -Wall -pedantic.
980 - I made the tests/ftpserver.pl work with the most commonly used ftp
981 operations. PORT, PASV, RETR, STOR, LIST, SIZE, USER, PASS all work now. Now
982 all I have to do is integrate the ftp server doings in the runtests.pl
983 script so that ftp tests can be run the same way http tests already run.
985 Daniel (20 November 2000)
986 - Made libcurl capable of dealing with any-length URLs. The former limit of
987 4096 bytes was a bit annoying when people wanted to use curl to really make
988 life tough on a web server. Now, the command line limit is the most annoying
989 but that can be circumvented by using a config file.
991 NOTE: there is still a 4096-byte limit on URLs extracted from Location:
994 - Corrected the spelling of 'resolve' in two error messages.
996 - Alexander Kourakos posted a bug report and a patch that corrected it! It
997 turned out that lynx and wget support lowercase environment variable names
998 where curl only looked for the uppercase versions. Now curl will use the
999 lowercase versions if they exist, but if they don't, it'll use the uppercase
1002 Daniel (17 November 2000)
1003 - curl_formfree() was added. How come no one missed that one before? I ran the
1004 test suite with the malloc debug enabled and got lots of "nice" warnings on
1005 memory leaks. The most serious one was this. There were also leaks in the
1006 cookie handling, and a few errors when curl failed to connect and similar
1007 things. More tests cases were added to cover up and to verify that these
1008 problems have been removed.
1010 - Mucho updated config file parser (I'm dead tired of all the bug reports and
1011 weird behaviour I get on the former one). It works slightly differently now,
1012 although I doubt many people will notice the differences. The main
1013 difference being that if you use options that require parameters, they must
1014 both be specified on the same line. With this new parser, you can also
1015 specify long options without '--' and you may separate options and
1016 parameters with : or =. It makes a config file line could look like:
1018 user-agent = "foobar and something"
1020 Parameters within quotes may contain spaces. Without quotes, they're
1021 expected to be a single non-space word.
1023 Had to patch the command line argument parser a little to make this work.
1025 - Added --url as an option to allow the URL to be specified this way. It makes
1026 way nicer config files. The previous way of specifying URLs in the config
1027 file doesn't work anymore.
1029 Daniel (15 November 2000)
1030 - Using certain characters in usernames or passwords for HTTP authentication
1031 failed. This was due to the mprintf() that had a silly check for letters,
1032 and if they weren't isprint() they weren't outputed "as-is". This caused
1033 passwords and usernames using '§' (for example) to fail.
1037 Daniel (15 November 2000)
1038 - 'tests/runtests.pl' now sorts the test cases properly when 'all' is used.
1040 Daniel (14 November 2000)
1041 - I fell over the draft-ietf-ftpext-mlst-12.txt Internet Draft titled
1042 "Extensions to FTP" that contains a defined way how the ftp command SIZE
1043 could be assumed to work.
1045 - Laurent Papier posted a bug report about using "-C -" and FTP uploading a
1046 file that isn't prsent on the server. The server might then return a 550 and
1047 curl will fail. Should it instead as Laurent Papier suggests, start
1048 uploading from the beginning as a normal upload?
1050 Daniel (13 November 2000)
1051 - Fixed a crash with the followlocation counter.
1053 - While writing test cases for the test suite, I discovered an old limitation
1054 that prevented -o and -T to be used at the same time. I removed this
1055 immediately as this has no relevance in the current libcurl.
1057 - Chris Faherty fixed a free-twice problem in lib/file.c
1059 - I fixed the perl http server problem in the test suite.
1063 Daniel (10 November 2000)
1064 - I've (finally) started working on the curl test suite. It is in the new
1065 tests/ directory. It requires sh and perl. There's a TCP server in perl and
1066 most of the other stuff running a pretty simple shell script.
1068 I've only made four test cases so far, but it proves the system can work.
1070 - Laurent Papier noticed that curl didn't set TYPE when doing --head checks
1071 for sizes on FTP servers. Some servers seem to return different sizes
1072 depending on whether ASCII or BINARY is used!
1074 - Laurent Papier detected that if you appended a FTP upload and everything was
1075 already uploaded, curl would hang.
1077 - Angus Mackay's getpass_r() in lib/getpass.c is now compliant with the
1078 getpass_r() function it seems some systems actually have.
1080 - Venkataramana Mokkapati detected a bug in the cookie parser and corrected
1081 it. If the cookie was set for the full host name (domain=full.host.com),
1082 the cookie was never sent back because of a faulty length comparison between
1083 the set domain length and the current host name.
1085 Daniel (9 November 2000)
1086 - Added a configure check for gethostbyname in -lsocket (OS/2 seems to need
1087 it). Added a check for RSAglue/rsaref for the cases where libcrypto is found
1088 but libssl isn't. I haven't verified this fix yet though, as I have no
1089 system that requires those libs to build.
1093 Daniel (7 November 2000)
1094 - Removed perror() outputs from getpass.c. Angus Mackay also agreed to a
1095 slightly modified license of the getpass.c file as the prototype was changed.
1097 Daniel (6 November 2000)
1098 - Added possibility to set a password callback to use instead of the built-in.
1099 They're controled with curl_easy_setopt() of course, the tags are
1100 CURLOPT_PASSWDFUNCTION and CURLOPT_PASSWDDATA.
1102 - Used T. Bharath's thinking and fixed the timers that showed terribly wrong
1103 times when location: headers were followed.
1105 - Emmanuel Tychon discovered that curl didn't really like user names only in
1106 the URL. I corrected this and I also fixed the since long living problem
1107 with URL encoded user names and passwords in the URLs. They should work now.
1109 Daniel (2 November 2000)
1110 - When I added --interface, the new error code that was added with it was
1111 inserted in the wrong place and thus all error codes from 35 and upwards got
1112 increased one step. This is now corrected, we're back at the previous
1113 numbers. All new exit codes should be added at the end.
1115 Daniel (1 November 2000)
1116 - Added a check for signal() in the configure script so that if sigaction()
1117 isn't present, we can use signal() instead.
1119 - I'm having a license discussion going on privately. The issue is yet again
1120 GPL-licensed programs that have problems with MPL. I am leaning towards
1121 making a kind of dual-license that will solve this once and for all...
1123 Daniel (31 October 2000)
1124 - Added the packages/ directory. I intend to let this contain some docs and
1125 templates on how to generate custom-format packages for various platforms.
1126 I've now removed the RPM related curl.spec files from the archive root.
1128 Daniel (30 October 2000)
1129 - T. Bharath brought a set of patches that bring new functionality to
1130 curl_easy_getinfo() and curl_easy_setopt(). Now you can request peer
1131 certificate verification with the *setopt() CURLOPT_SSL_VERIFYPEER option
1132 and then use the CURLOPT_CAINFO to set the certificate to verify the remote
1133 peer against. After an such an operation with a verification request, the
1134 *_getinfo() option CURLINFO_SSL_VERIFYRESULT will return information about
1135 whether the verification succeeded or not.
1137 Daniel (27 October 2000)
1138 - Georg Horn brought us a splendid patch that solves the long-standing
1139 annoying problem with timeouts that made curl exit with silly exit codes
1140 (which as been commented out lately). This solution is sigaction() based and
1141 of course then only works for unixes (and only those unixes that actually
1142 have the sigaction() function).
1144 Daniel (26 October 2000)
1145 - Björn Stenberg supplied a patch that fixed the flaw mentioned by Kevin Roth
1146 that made the password get echoed when prompted for interactively. The
1147 getpass() function (now known as my_getpass()) was also fixed to not use any
1148 static buffers. This also means we cannot use the "standard" getpass()
1149 function even for those systems that have it, since it isn't thread-safe.
1151 - Kevin Roth found out that if you'd write a config file with '-v url', the
1152 url would not be used as "default URL" as documented, although if you wrote
1153 it 'url -v' it worked! This has been corrected now.
1155 - Kevin Roth's idea of using multiple -d options on the same command line was
1156 just brilliant, and I couldn't really think of any reason why we shouldn't
1157 support it! The append function always append '&' and then the new -d
1158 chunk. This enables constructs like the following:
1160 curl -d name=daniel -d age=unknown foobarsite.com
1162 Daniel (24 October 2000)
1163 - I fixed the lib/memdebug.c source so that it compiles on Linux and other
1164 systems. It will be useful one day when someone else but me wants to run the
1165 memory debugging system.
1167 Daniel (23 October 2000)
1168 - I modified the maketgz and configure scripts, so that the configure script
1169 will fetch the version number from the include/curl/curl.h header files, and
1170 then the maketgz doesn't have to rebuild the configure script when I build
1173 - Björn Stenberg and Linus Nielsen correctly pointed out that curl was silly
1174 enough to not allow @-letters in passwords when they were specified with the
1175 -u or -U flags (CURLOPT_USERPWD and CURLOPT_PROXYUSERPWD). This also
1176 suggests that curl probably should url-decode the password piece of an URL
1177 so that you could pass an encoded @-letter there...
1179 Daniel (20 October 2000)
1180 - Yet another http server barfed on curl's request that include the port
1181 number in the Host: header always. I now only include the port number if it
1182 isn't the default (80 for HTTP, 443 for HTTPS). www.perl.com turned out to
1183 run one of those nasty servers.
1185 - The PHP4 module for curl had problems with referer that seems to have been
1186 corrected just yesterday. (Sterling Hughes of the PHP team confirmed this)
1188 Daniel (17 October 2000)
1189 - Vladimir Oblomov reported that the -Y and -y options didn't work. They
1190 didn't work for me either. This once again proves we should have that test
1193 - I finally changed the error message libcurl returns if you try a https://
1194 URL when the library wasn't build with SSL enabled. It will now return this
1196 "libcurl was built with SSL disabled, https: not supported!"
1198 I really hope it will make it a bit clearer to users where the actual
1203 Daniel (16 October 2000)
1204 - I forgot to remove some of the malloc debug defines from the makefiles in
1205 the release archive (of course).
1209 Daniel (16 October 2000)
1210 - The buffer overflow mentioned below was posted to bugtraq on Friday 13th.
1212 Daniel (12 October 2000)
1213 - Colin Robert Phipps elegantly corrected a buffer overflow. It could be used
1214 by an evil ftp server to crash curl. I took the opportunity of replacing a
1215 few other sprintf()s into snprintf()s as well.
1217 Daniel (11 October 2000)
1218 - Found some more memory leaks. This new simple memory debugger has turned out
1223 Daniel (9 October 2000)
1224 - Florian Koenig pointed out that the bool typedef in the curl/curl.h include
1225 file was breaking PHP 4.0.3 compiling. The bool typedef is not used in the
1226 public interface and was wrongly inserted in that header file.
1228 - Jörg Hartroth corrected a minor memory leak in the src/urlglob.c stuff. It
1229 didn't harm anyone since the memory is free()ed on exit anyway.
1231 - Corrected the src/main.c. We use the _MPRINTF_REPLACE #define to use our
1232 libcurl-printf() functions. This gives us snprintf() et al on all
1233 platforms. I converted the allocated useragent string to one that uses a
1236 - I've set an #if 0 section around the Content-Transfer-Encoding header
1237 generated in lib/formdata.c. This will hopefully make curl do more
1238 PHP-friendly multi-part posts.
1242 Daniel (9 October 2000)
1243 - Nico Baggus found out that curl's ability to force a ASCII download when
1244 using FTP was no longer working! I corrected this. This problem was probably
1245 introduced when I redesigned libcurl for version 7.
1247 - Georg Horn provided a source example that proved a memory leak in libcurl.
1248 I added simple memory debugging facilities and now we can make libcurl log
1249 all memory fiddling functions. An additional perl script is used to analyze
1250 the output logfile and to match malloc()s with free()s etc. The memory leak
1251 Georg found turned out to be the main cookie struct that cookie_cleanup()
1252 didn't free! The perl script is named memanalyze.pl and it is available in
1253 the CVS respository, not in the release archive.
1255 Daniel (8 October 2000)
1256 - Georg Horn found a GetHost() problem. It turned out it never assigned the
1257 pointer in the third argument properly! This could make a crash, or at best
1262 Daniel (6 October 2000)
1263 - Is the -F post following the RFC 1867 spec? We had this dicussion on the
1264 mailing list since it appears curl can't post -F form posts to a PHP
1265 receiver... I've been in touch with the PHP developers about this.
1267 - Domenico Andreoli found out that the long option '--proxy' wasn't working
1268 anymore! The option parser got confused when I added the --proxytunnel for
1269 7.3. This was indeed a very old flaw that hasn't turned up until now...
1271 - Jörn Hartroth provided patches, updated makefiles and two new files for DLL
1272 stuff on win32. He also pointed out that lib source files were compiled with
1273 -I../src which isn't only wrong but plain stupid!
1275 - Troels Walsted Hansen fixed a problem with HTTP resume. Curl previously used
1276 a local variable badly, that could lead to crashes.
1280 Daniel (4 October 2000)
1281 - More docs written. The curl_easy_getinfo.3 man page is now pretty accurate,
1282 as is the -w section in curl.1. I added two options to enable the user to
1283 get information about the received headers' size and the size of the HTTP
1284 request. T. Bharath requested them.
1286 Daniel (3 October 2000)
1287 - Corrected a sever free() before use in the new add_buffer_send()! ;-)
1291 Daniel (3 October 2000)
1292 - Jason S. Priebe sent me patches that changed the way curl issues HTTP
1293 requests. The entire request is now issued in one single shot. It didn't do
1294 this previously, and it has turned out that since the common browsers do it
1295 this way, some sites have turned out to work with browsers but not with
1296 curl! Although this is not a client-side problem, we want to be able to
1297 fully emulate browsers, and thus we have now adjusted the networking layer
1298 to slightly more appear as a browser. I adjusted Jason's patch, the faults
1301 Daniel (2 October 2000)
1302 - Anyone who ever uploaded data with curl on a slow link has noticed that the
1303 progess meter is updated very infrequently. That is due to the large buffer
1304 size curl is using. It reads 50Kb and sends it, updates the progress meter
1305 and loops. 50Kb is very much on a slow link, although it is pretty neat to
1308 I've now made an adjustment that makes curl use a 2Kb buffer for uploads to
1309 start with. If curl's average upload speed is faster than buffer size bytes
1310 per second, curl will increase the used buffer size up to max 50Kb. It
1311 should make the progress meter work better.
1315 Daniel (29 September 2000)
1316 - Ripped out the -w stuff from the library and put in the curl tool. It gets
1317 all the relevant info from the library using the new curl_easy_getinfo()
1320 - brad at openbsd.org mailed me a patch that corrected my kerberos mistake and
1321 removed a compiler warning from hostip.c that OpenBSD people get.
1323 Daniel (28 September 2000)
1324 - Of course (I should probably get punished somehow) I didn't properly correct
1325 the #include lines for the base64 stuff in the kerberos sources in the just
1326 released 7.3 package. They still include the *_krb.h files! Now, the error
1327 is sooo very easy to spot and fix so I won't bother with a quick bug fix
1328 release. I'll post a patch whenever one is needed instead. It'll be
1329 available in the CVS in a few minutes anyway.
1333 Daniel (28 September 2000)
1334 - Removed the base64_krb.[ch] files. They've now replaced the former
1337 Daniel (26 September 2000)
1338 - Updated some docs.
1340 - I changed the OpenSSL fix to work with older versions as well. The posted
1341 patch was only working with 0.9.6 and no older ones.
1345 Daniel (25 September 2000)
1346 - Erdmut Pfeifer informed us that curl didn't build with OpenSSL 0.9.6 and
1347 showed us what needed to get patched in order to make it build properly
1350 - Dirk Kruschewski found a bug in the cookie parser. I made an alternative
1351 approach to the solution Dirk himself suggested. The bug made a cookie
1352 header that didn't end with a trailing semicolon to not get parsed.
1354 - I've marked -c and -t deprecated now. If you use any of them, curl will tell
1355 you to use "-C -" or "-T -" instead. I don't think occupying two letters for
1356 nearly identical functions is good use. Also, -T - kind of follows the curl
1357 tradition of using - for stdin where a file name is expected.
1359 Daniel (23 September 2000)
1360 - Martin Hedenfalk provided the patch that finally made the krb4 ftp upload
1363 Daniel (21 September 2000)
1364 - The kerberos code is not quite thread-safe yet. There are a few more globals
1365 that need to be take care of. Let's get the upload working first!
1367 Daniel (20 September 2000)
1368 - Richard Prescott solved another name lookup buffer size problem. I took this
1369 opportunity to rewrite the GetHost() function. With these large buffer
1370 sizes, I think keeping them as local arrays quickly turn ugly. I now use
1371 malloc() to get the buffer memory. Thanks to this, I now can realloc() to a
1372 large buffer in case of demand (errno == ERANGE) in case a solution like
1373 that would become necessary. I still want to avoid that kind of nastiness.
1375 - Tried to compile and run curl on Linux for alpha and FreeBSD for alpha. Went
1376 as smooth as it could.
1378 - Added a docs/examples directory with two tiny example sources that show how
1379 to use libcurl. I hope users will supply me with more useful examples
1382 - Applied a patch by Jörn Hartroth to no longer use the word 'inteface' in the
1383 config struct in the src/main.c file since certain compilers have that word
1384 "reservered". I figure that is some kind of C++ decease.
1386 - Updated the curl.1 man page with --interface and --krb4.
1388 - Modified the base64Encode() function to work like the kerberos one, so that
1389 I could remove the use of that. There is no need for *two* base64 encoding
1394 Daniel (19 September 2000)
1395 - The kerberos4-layer source code that is much "influenced" by the original
1396 krb4 source code, through yafc into curl, was using quite a lot of global
1397 variables. libcurl can't work properly with globals like that why I had to
1398 clean up almost every function in the new security.c to make them use
1399 connection specific variables instead of the globals. I just hope I didn't
1400 destroy anything now... :-) configure updated, version string now reflects
1401 krb4 built-in. It almost works now. Only uploads are still being naughty.
1405 Daniel (18 September 2000)
1406 - Martin Hedenfalk supplied a major patch that introduces krb4-ftp support to
1407 curl. Martin is the primary author of the ftp client named yafc and he did
1408 not hesitate to help us implement this when I asked him. Many and sincere
1409 thanks to a splendid effort. It didn't even take many hours!
1411 - Stephen Kick supplied a big patch that introduces the --interface flag to
1412 the curl tool and CURLOPT_INTERFACE for libcurl. It allows you to specify an
1413 outgoing interface to use for your request. This may not work on all
1414 platforms. This needs testing.
1416 - Richard Prescott noticed that curl on Tru64 unix could core dumped if the
1417 name didn't resolve properly. This was due to the GetHost() function not
1418 returning an error even though it failed on some platforms!
1420 Daniel (15 September 2000)
1421 - Updated all sorts of documents in regards to the new proxytunnel support.
1425 Daniel (15 September 2000)
1426 - Kai-Uwe Rommel pointed out a problem in the httpproxytunnel stuff for ftp.
1427 Adjusted it. Added better info message when setting up the tunnel and the
1428 pasv message when doing the second connect.
1432 Daniel (15 September 2000)
1433 - libcurl now allows "httpproxytunnel" to an arbitrary host and port name. The
1434 second connection on ftp needed that.
1436 - TheArtOfHTTPScripting was corrected all over. I both type and spell really
1439 Daniel (14 September 2000)
1440 - -p/--proxytunnel was added to 'curl'. It uses the new
1441 CURLOPT_HTTPPROXYTUNNEL libcurl option that allows "any" protocol to tunnel
1442 through the specified http proxy. At the moment, this should work with ftp.
1444 Daniel (13 September 2000)
1445 - Jochen Schaeuble found that file:// didn't work as expected. Corrected this
1446 and mailed the patch to the mailing list.
1448 Daniel (7 September 2000)
1449 - I changed the #define T() in curl.h since it turned out it wasn't really
1450 a good symbol to use (when you compiled PHP with curl as a module, that
1451 define collided with some IMAP define or something). This was posted to the
1454 - I added extern "C" stuff in two header files to better allow libcurl usage
1455 in C++ sorces. Discussions on the libcurl list with Danny Horswell lead to
1460 Daniel (31 August 2000)
1461 - Albert Chin-A-Young fixed the configure script *again* and now it seems to
1462 detect Linux name resolving properly! (heard that before?)
1464 - Troels Walsted Hansen pointed out that downloading a file containing the
1465 letter '+' from an ftp server didn't work. It did work from HTTP though and
1466 the reason was my lame URL decoder.
1468 - I happened to notice that -I didn't at all work on ftp anymore. I corrected
1473 Daniel (30 August 2000)
1474 - Understanding AIX is a hard task. I believe I'll never figure out why they
1475 solve things so differently from the other unixes. Now, I'm left with the
1476 AIX 4.3 run-time warnings about duplicate symbols that according to this
1477 article (http://www.geocrawler.com/archives/3/405/1999/9/0/2593428/) is a
1478 libtool flaw. I tried the mentioned patch, although that stops the linking
1481 So, if I select to ignore the ld warnings there are compiler warnings that
1482 fill the screen pretty bad when curl compiles. It turns out that if I want
1483 to '#include <arpa/inet.h>', I can get tid of the warnings by include the
1484 following three include files before that one:
1486 #include <net/if_dl.h>
1487 #include <sys/mbuf.h>
1488 #include <netinet/if_ether.h>
1490 Now, is it really sane to add those include files before arpa/inet.h in all
1491 the source files that include it?
1493 Thanks to Albert Chin-A-Young at thewrittenword.com who gave me the AIX
1494 login to try everything on.
1496 Daniel (24 August 2000)
1497 - Jan Schmidt supplied us a new VC6 makefile for Windows as the previous one
1498 was not up to date but lacked several object files.
1500 - More work on the naming.
1502 - Albert Chin-A-Young provided a configure-check for large file support, as
1503 some systems seem to need that for them to work. Had to change the position
1504 for the config.h include file in every .c file in the libcurl dir...
1506 - As suggested on the mailing list (by Troy Engel), I did use a --data-binary
1507 option instead of the messy way I've left described below. It seems to
1508 work. The libcurl fix remained the same as yesterday.
1510 Daniel (23 August 2000)
1511 - Back on the -d stripping newlines thing. The 'plain post' thing was added
1512 when I had no thought of that one could actually post binary data with
1513 it. Now, I have to add this functionality in a graceful manner and I think
1514 I've managed to come up with a way: '-d @file;binary' will thus post the
1515 file binary, exactly as its contents are. It is implemented with a new
1516 *setopt() option (CURLOPT_POSTFIELDSIZE) to set the postfield size, since
1517 libcurl can't strlen() the data in these cases.
1519 - Albert Chin-A-Young made some very serious efforts and all the name
1520 resolving problems seem to have been sorted out now on all the platforms
1521 that previously showed them. I'll make another release now anyday because of
1524 - The FAQ was much enhanced when it comes to the licensing issues thanks to
1527 Daniel (21 August 2000)
1528 - Rick Welykochy pointed out a problem when you use -d to post and you want to
1529 keep the newlines, as curl strips them off as a bonus before posting...
1530 This needs to be addressed.
1534 Daniel (21 August 2000)
1535 - Got more people involved in the gethostbyname_r() mess. Caolan McNamara sent
1536 me configure-code that turned out to be very similar to my existing tests
1537 which only make me more sure I'm on the right path. I changed the order of
1538 the tests slightly, as it seems that some compilers don't yell error if a
1539 function is used with too many parameters. Thus, the first tested function
1540 will seem ok... Let's hope more compilers think of too-few parameters as bad
1541 manners, as we're now trying the functions in that order; fewer first. I
1542 should also add that Lars Hecking mailed me and volunteered to run tests on
1543 a few odd systems. Coalan is keeping his work over at
1544 http://www.csn.ul.ie/~caolan/publink/gethostbyname_r/. Might be handy in the
1547 Daniel (18 August 2000)
1548 - I noticed I hadn't increased the name lookup buffer in lib/ftp.c. I don't
1549 think this is the reason for the continued trouble though.
1551 Daniel (17 August 2000)
1552 - Fred Noz corrected my stupid mistakes in the gethostbyname_r() fluff. It
1553 should affect some AIX, Digital Unix and HPUX 10 systems.
1555 Daniel (15 August 2000)
1556 - Mathieu Legare compiled and build 7.1 without errors on both AIX 4.2 as well
1557 as AIX 4.3. Now why did problems occur before?
1559 - Fred Noz reported a -w/--write-out bug that caused it to malfunction when
1560 used combined with multiple URL retrievales. All but the first display got
1563 Daniel (11 August 2000)
1564 - Jason Priebe and an anonymous friend found some host names the Linux version
1565 of curl could not resolve. It turned out the buffer used to retrieve that
1566 information was too small. Fixed. One could argue about the usefulness of
1567 not having the slightest trace of a man page for gethostbyname_r() on my
1568 Linux Redhat installation...
1570 Daniel (10 August 2000)
1571 - Balaji S Rao was first in line to note the missing possibility to replace
1572 the Content-Type: and Content-Length: headers when doing -d posts. I added
1573 the possibility just now. It seems some people wants to do standard posts
1574 using custom Content-Types.
1576 Daniel (8 August 2000)
1577 - Mike Dowell correctly discovered that curl did not approve of URLs with no
1578 user name but password. As in 'http://:foo@haxx.se'. I corrected this.
1582 Daniel (7 August 2000)
1583 - My AIX 4 fix does not work. I need help from a AIX 4 hacker.
1585 - I added my new document in the docs directory. It is aimed to become a sort
1586 of tutorial on how to do HTTP scripting with curl.
1588 Daniel (4 August 2000)
1589 - Working with Rich Gray on compiling curl for lots of different platforms.
1590 My fix for AIX 3.2 was not good enough and was slightly changed, I had to
1591 move an include file before another, as is now described in the source.
1593 AIX 4.2 (4.X?) has different gethostbyname_r() and gethostbyaddr_r()
1594 functions that the configure script didn't check for and thus the compile
1595 broke with an error. I have now changed the gethostbyname_r() check in the
1596 configure file to support all three versions of both these functions. My
1597 implementation that uses the AIX-style is though not yet verified and I may
1598 get problems to fix it if it turns out to bug since I don't have access to
1599 any system using that.
1601 For problems like that, I made the configure script allow --disable-thread
1602 to completely switch off the check for threadsafe versions of a few
1603 functions and thus go with the "good old versions" that tend to work
1604 although will break thread-safeness for libcurl. Most people won't use
1605 libcurl for other things than curl though, and curl doesn't need a
1608 - Working on my big tutorial about HTTP scripting with curl.
1610 Daniel (1 August 2000)
1611 - Rich Gray spotted a problem in src/setup.h caused by a #define strequal()
1612 that was just a left-over from passed times. The strequal() is now a true
1613 function supplied by libcurl for a portable case insensitive string
1614 comparison. I added the prototypes in include/curl.h and removed the
1615 now obsolete #define.
1617 - Igor Khristophorov made a fix to allow resumed download from Sun's
1618 JavaWebServer/1.1.1. It seems that their server sends bad Content-Range
1621 - The makefiles forced a static library build, which is bad since we now use
1622 libtool and thus have excellent shared library support! Albert Chin-A-Young
1627 Daniel (1 August 2000)
1628 - Albert Chin-A-Young pointed out that 'make install' did not properly create
1629 the header include directory, why it failed to install the header files as
1630 it should. Automake isn't really equipped to deal with subdirectories
1631 without Makefiles in any nice way. I had to run ahead and add Makefiles in
1632 both include and include/curl before I managed to create a top-level
1633 makefile that succeeds in install everything properly!
1635 - Ok, no more "features" added now. Let's just verify that there's no major
1638 Daniel (31 July 2000)
1639 - Both Jeff Schasny and Ketil Froyn asked me how to tell curl not to send one
1640 of those internally generated headers. They didn't settle with the blank
1641 ones you could tell curl to use. I rewrote the header-replace stuff a
1642 little. Now, if you replace an internal header with your own and that new
1643 one is a blank header you will only remove the internal one and not get any
1644 blank. I couldn't figure out any case when you want that blank header.
1646 Daniel (29 July 2000)
1647 - It struck me that the lib used localtime() which is not thread-safe, so now
1648 I use localtime_r() in the systems that has it.
1650 - I went through this entire document and removed all email addresses and left
1651 names only. I've really made an effort to always note who brought be bug
1652 reports or fixes, but more and more people ask me to remove the email
1653 addresses since they become victims for spams this way. Gordon Beaton got me
1656 Daniel (27 July 2000)
1657 - Jörn Hartroth found out that when you specified a HTTP proxy in an
1658 environment variable and used -L, curl failed in the second fetch. I
1659 corrected this problem and posted a patch to the list. No need for an extra
1660 beta release just for this.
1664 Daniel (27 July 2000)
1665 - So, libtool replaced two of my files with symbolic links and I forgot to add
1666 the two new libtool files to the release archive (and they were added as
1667 symlinks as well!) This of course lead to that the configure script failed
1672 Daniel (25 July 2000)
1673 - Kristian Köhntopp <kris at koehntopp.de> brought a fix that makes libcurl
1674 libtoolified, just as we've wanted for a while now. He also made the
1675 recently added man pages get installed properly on 'make install' and some
1676 other nice cleanups.
1678 - In a discussion with Eetu Ojanen it struck me that if we use curl to get a
1679 page using a password, and that page then sends a Location: to another
1680 server that curl follows, curl will send the user name and password to that
1683 Now, I'll never be able to make curl do Location: following all that perfect
1684 and you're all sooner or later required to write a script to do several
1685 fetches when you're doing advanced stuff, but now I've modified curl to at
1686 least *only* send the user name and password to the original server. Which
1687 means that if get a page from server A with a password, that forwards curl
1688 to server B, curl won't use the password there. If server B then forwards
1689 curl back to server A again, the password will be used again.
1691 This is not a perfect implementation, as in a browser case it would only use
1692 the password if the left-prefix of the first path is the same. I just think
1693 that this fix prevents a somewhat lurky "security hole".
1695 As a side-note in this subject: HTTP passwords are sent in cleartext and
1696 will never be considered to be safe or secure. Use HTTPS for that.
1698 - As discussed on the mailing list, I converted the FTP response reading
1699 function into using select() which then allows timeouts (even under win32!)
1700 if the command-reply session gets too slow or dies completely. I made a
1701 default timeout on 3600 seconds unless anything else is specified, since I
1702 don't think anyone wants to wait more than that for a single character to
1705 - Torsten Foertsch <torsten.foertsch at gmx.net> brought a set of fixes for
1706 the rfc1867 form posts. He introduced 'name=<file' which brings a means to
1707 suuply very large text chunks read from the given file name. It differs from
1708 'name=@file' in the way that this latter thing is marked in the uploaded
1709 contents as a file upload, while the first is just text (as in a input or
1710 textarea field). Torsten also corrected a bug that would happen if you used
1711 %s or similar in a -F file name.
1713 - As discovered by Nico Baggus <Nico.Baggus at mail.ing.nl>, when transferring
1714 files to/from FTP using type ASCII curl should not expect the transfer to be
1715 the exact size reported by the server as the file size. Since ASCII may very
1716 well mean that the content is translated while transfered, the final size
1717 may very well differ. Therefor, curl now ignores the file size when doing
1718 ASCII transfers in FTP.
1720 Daniel (24 July 2000)
1721 - Added CURLOPT_PROXYPORT to the curl_easy_setopt() call to allow the proxy
1722 port number to be set separately from the proxy host name.
1724 - Andrew <andrew at ugh.net.au> pointed out a netrc manual bug.
1726 - The FTP transfer code now accepts a 250-code as well as the previously
1727 accepted 226, after a successful file transfer. Mohan <mnair at
1728 evergreen-funds.com> pointed this out.
1730 - The check for *both* nsl and socket was never added in the v7 configure.in
1731 when I moved the main branch. I re-added that check to configure.in. This was
1732 discovered by Rich Gray.
1734 - Howard, Blaise <Blaise.Howard at factiva.com> pointed out a missing free() in
1735 curl_disconnect() which of course meant libcurl ate memory.
1737 - Brian E. Gallew noted that the HTTP 'Host:' header curl sent did not
1738 properly include the port number if non-default ports were used. This should
1739 now have been fixed.
1741 - HTTP connect errors now return errors earlier. This was most notably causing
1742 problems when the HTTPS certificate had problems and later caused a crash.
1743 Many thanks to Gregory Nicholls <gnicholls at level8.com> for discovering
1744 and suggesting a fix...
1746 Daniel (21 June 2000)
1747 - After a "bug report" I received where the user was using both -F and -I in a
1748 HTTP request (it severly confused the library I should add), I added some
1749 checks to src/main.c that prevents setting more than one HTTP request
1750 command, no matter what the user wants! ;-)
1754 Daniel (20 June 2000)
1755 - I did a major replace in many files to use the new curl domain haxx.se
1756 instead of the previous one.
1758 - As Eetu Ojanen suggested, I finally took the step and now libcurl no longer
1759 makes a POST after it has followed a location. When the initial POST has
1760 been done, it'll turned into a GET for the further requests. This is only
1761 interesting when using -L/--location *and* doing a POST at the same time.
1763 While messing with this, I added another weird feature I call 'auto
1764 referer'. If you append ';auto' to the right of a given referer string (or
1765 only use that string as referer), libcurl will automatically set the
1766 previoud URL as refered when it follows a Location: and gets a succeeding
1769 - My hero Rich Gray found the very obscure FTP bug that happened to him only
1770 when passing through a particular firewall and using the PORT command. It
1771 turned out that PORT was the only command in the lib/ftp.c source that
1772 didn't send a proper \r\n sequence but instead used the faulty \n which as
1773 it seemed is supported by most major ftp servers... :-O
1777 Daniel (16 June 2000)
1778 - I had avoided this long enough now, so I moved the alternative progress bar
1779 stuff from the lib and added it to the client code. This is now using the
1780 recently added progress callback and it seems to work pretty much like
1781 before. Since it is only one progress bar and you and download and upload at
1782 the same time, this bar shows the combined progress of both directions. This
1783 code was just ported from the old place to this, Lars is still our saviour!
1784 ;-) This also made the documentation more accurate since I never removed
1785 this function from any docs! Although I now removed the CURLOPT_PROGRESSMODE
1786 from the library since the lib has only one internal progress meter and it
1787 will never get another. It is although likely that the internal one also
1788 will be moved to the client code in the future (when I have other means of
1789 getting the writeout data and move that too to the client).
1791 - I took the opportunity to verify that standard progress meter works and I
1792 found out it didn't get inited properly. Grrr. I corrected that as well.
1794 Daniel (15 June 2000)
1795 - I thought I'd better verify that the -F option still works in v7 and of
1796 course it didn't... :-/ Anyway, I had the problems I could discover
1797 corrected. About one month of beta testing and not a single person has used
1798 this feature with v7?
1800 - Björn correctly pointed out that the --progress-bar still doesn't work in
1803 Daniel (14 June 2000)
1804 - Tim Tassonis discovered that curl 7 didn't handle normal http POST as it
1805 should. I corrected this.
1809 Daniel (14 June 2000)
1810 - Björn Stenberg pointed out several problems (related to win32 compiling):
1811 lib/strequal.c had a bad #ifdef for one of the string comparisons (win32)
1812 src/main.c had several minor problems
1813 lib/makefile.m32 had getpass.[co] twice
1814 src/config-win32.h lacked the HAVE_FCNTL_H define
1815 both config-win32.h files now only set the HAVE_UNISTD_H define if the
1816 define MINGW32 is set, and I modified src/makefile.m32 and lib/makefile.m32
1821 Daniel (14 June 2000)
1822 - Applied Luong Dinh Dung's comments about a few win32 compile problems.
1824 - Applied Björn Stenberg's suggested fix that turns the win32 stdout to
1825 binary. It won't do it if the -B / --use-ascii option is used. That option
1826 is now an extended version of the previous -B /--ftp--ascii. The flag was
1827 already in use be the ldap as well so the new name fits pretty good. The
1828 libcyrl CURLOPT_TRANSFERTEXT was also introduced as an alias to the now
1829 obsolete CURLOPT_FTPASCII. Can't verify this fix myself as I have no win32
1832 Daniel (13 June 2000)
1833 - Luong Dinh Dung <dung at sch.bme.hu> found a problem in curl_easy_cleanup()
1834 since it free()ed the main curl struct *twice*. This is now corrected.
1836 Daniel (9 June 2000)
1837 - Updated the RESOURCES file, added a README.win32 file.
1839 Daniel (8 June 2000)
1840 - So I finally added the progress callback to the *setopt() options and it
1841 should work now. I don't have the energy to write any test program for it
1843 - Made the callback function typedefs public in curl/curl.h for comfort. Just
1844 in case anyone wanna fiddle with such pointers.
1845 - Updated the curl_easy_setopt() man page accordingly.
1849 Daniel (2 June 2000)
1850 - I noticed that when doing Location: following, we lost custom headers in all
1851 but the first request.
1852 - Removed the 'HttpPost' struct and moved the header stuff to the more generic
1854 - Added some better slist-cleanups in src/main.c
1858 Daniel (31 May 2000)
1859 - So I discovered that I released the 7.0.2beta without it being able to
1860 compile under Linux. gethostbyname_r() and gethostbyaddr_r() turned out to
1861 feature a different amount of arguments on different systems so I had to add
1862 a configure check for this and adjust the code slightly.
1866 Daniel (29 May 2000)
1867 - Corrected the bits.* assignments when using CURLOPT options that only
1868 toggles one of those bits.
1870 - Applied the huge patches from David LeBlanc <dleblanc at qnx.com> that add
1871 usage of the gethostbyname_r() and similar functions in case they're around,
1872 since that make libcurl much better threadsafe in many systems (such as
1873 solaris). I added the checks for these functions to the configure script.
1875 I can't explain why, but the inet_ntoa_r() function did not appear in my
1876 Solaris include files, I had to add my own include file for this for now.
1878 Daniel (22 May 2000)
1879 - Jörn Hartroth brought me fixes to make the win32 version compile properly as
1880 well as a rename of the 'interface' field in the urldata struct, as it seems
1881 to be reserved in some gcc versions!
1883 - Rich Gray struck back with yet some portability reports. Data General DG/UX
1884 needed a little fix in lib/ldap.c since it doesn't have RTLD_GLOBAL defined.
1885 More fixes are expected as a result of Richies very helpful work.
1889 Daniel (21 May 2000)
1890 - Updated lots of #defines, enums and variable type names in the library. No
1891 more weird URG or URLTAG prefixes. All types and names should be curl-
1892 prefixed to avoid name space clashes. The FLAGS-parameter to the former
1893 curl_urlget() has been converted into a bunch of flags to use in separate
1894 setopt calls. I'm still focusing on the easy-interface, as the curl tool is
1897 - Bjorn Reese has provided me with an asynchronous name resolver that I plan
1898 to use in upcoming versions of curl to be able to gracefully timeout name
1903 Daniel (18 May 2000)
1904 - Introduced LIBCURL_VERSION_NUM to the curl.h include file to better allow
1905 source codes to be dependent on the lib version. This define is now set to
1906 a dexadecimal number, with 8 bits each for major number, minor number and
1907 patch number. In other words, version 1.2.3 would make it 0x010203. It also
1908 makes a larger number a newer version.
1910 Daniel (17 May 2000)
1911 - Martin Kammerhofer correctly pointed out several flaws in the FTP range
1912 option. I corrected them.
1913 - Removed the win32 winsock init crap from the lib to the src/main.c file
1914 in the application instead. They can't be in the lib, especially not for
1915 multithreaded purposes.
1917 Daniel (16 May 2000)
1918 - Rewrote the src/main.c source to use the new easy-interface to libcurl 7.
1919 There is still more work to do, but the first step is now taken.
1920 <curl/easy.h> is the include file to use.
1922 Daniel (14 May 2000)
1923 - FTP URLs are now treated slightly different, more according to RFC 1738.
1924 - FTP sessions are now performed differently, with CWD commands to change
1925 directory instead of RETR/STOR/LIST with the full path. Discussions with
1926 Rich Gray made me notice these problems.
1927 - Janne Johansson discovered and corrected a buffer overflow in the
1929 - I had to add a lib/strequal.c file for doing case insensitive string
1930 compares on all platforms.
1932 Daniel (8 May 2000):
1933 - Been working lots on the new lib.
1934 - Together with Rich Gray, I've tried to adjust the configure script to work
1935 better on the NCR MP-RAS Unix.
1937 Daniel (2 May 2000):
1938 - Albert Chin-A-Young pointed out that I had a few too many instructions in
1939 configure.in that didn't do any good.
1941 Daniel (24 April 2000):
1942 - Added a new paragraph to the FAQ about what to do when configure can't
1943 find OpenSSL even though it is installed. Supplied by Bob Allison
1945 Daniel (12 April 2000):
1946 - Started messing around big-time to convert the old library interface to a
1949 Daniel (8 April 2000):
1950 - Made the progress bar look better for file sizes between 9999 kilobytes
1951 and 100 megabytes. They're now displayed XX.XM.
1952 - I also noticed that ftp fetches through HTTP proxies didn't add the user
1953 agent string. It does now.
1954 - Habibie <habibie at MailandNews.com> supplied a pretty good way to build RPMs
1955 on a Linux machine. It still a) requires me to be root to do it, b) leaves
1956 the rpm packages laying at some odd place on my disk c) doesn't work to
1957 build the ssl version of curl since I didn't install openssl from an rpm
1958 package so now the rpm crap thinks I don't have openssl and refuses to build
1959 a package that depends on ssl... Did I mention I don't get along with RPM?
1960 - Once again I received a bug report about autoconf not setting -L prior to -l
1961 on the command line when checking for libs. In this case it made the native
1962 cc compiler on Solaris 7 to fail the OpenSSL check. This has previously been
1963 reported to cause problems on HP-UX and is a known flaw in autoconf 2.13. It
1964 is a pity there's no newer release around...
1966 Daniel (4 April 2000):
1967 - Marco G. Salvagno supplied me with two fixes that
1968 appearantly makes the OS/2 port work better with multiple URLs.
1970 Daniel (2 April 2000):
1971 - Another Location: fix. This time, when curl connected to a port and then
1972 followed a location with an absolute URL to another port, it misbehaved.
1974 Daniel (27 March 2000):
1975 - H. Daphne Luong pointed out that curl was wrongly
1976 messing up the proxy string when fetching a document through a http proxy,
1977 which screwed up multiple fetches such as in location: followings.
1979 Daniel (23 March 2000):
1980 - Marco G. Salvagno corrected my badly applied patch he
1981 actually already told me about!
1983 - H. Daphne Luong brought me a fix that now makes curl
1984 ignore select() errors in the download if errno is EINTR, which turns out to
1985 happen every now and then when using libcurl multi-threaded...
1987 Daniel (22 March 2000):
1988 - Wham Bang supplied a couple of win32 fixes. HAVE_UNAME
1989 was accidentally #defined in config-win32.h, which it shouldn't have been.
1990 The HAVE_UNISTD_H is not defined when compiling with the Makefile.vc6
1991 makefile for MS VC++.
1993 Daniel (21 March 2000):
1994 - I removed the AC_PROG_INSTALL macro from configure.in, since it appears that
1995 one of the AM_* macros searches for a BSD compatible install already. Janne
1996 Johansson made me aware of this.
2000 Daniel (21 March 2000):
2001 - Paul Harrington quickly pointed out to me that 6.5.1
2002 crashes hard. I upload 6.5.2 now as quickly as possible! The problem was
2003 the -D adjustments in src/main.c.
2007 Daniel (20 March 2000):
2008 - An anonymous post on sourceforge correctly pointed out a possible buffer
2009 overflow in the curl_unescape() function for URL conversions. The main
2010 problem with this bug is that the ftp download uses that function and this
2011 single- byte overflow could lead to very odd bugs (as one reported by Janne
2014 Daniel (19 March 2000):
2015 - Marco G. Salvagno supplied me with a series of patches
2016 that now allows curl to get compiled on OS/2. It even includes a section in
2017 the INSTALL file. Very nice job!
2019 Daniel (17 March 2000):
2020 - Wham Bang supplied a patch for the lib/Makefile.vc6
2021 file. We still need some fixes for the config-win32.h since it appears that
2022 VC++ and mingw32 have different opinions about (at least) unistd.h's
2025 Daniel (15 March 2000):
2026 - I modified the -D/--dump-header workings so that it doesn't write anything
2027 to the file until it needs to. This way, you can actually use -b and -D
2028 on the same file if you want repeated invokes to store and read the cookies
2029 in that one single file.
2031 - Poked around in lots of texts. Added the BUGS file for bug reporting stuff.
2032 Added the classic HTTP POST question to the FAQ, removed some #ifdef WIN32
2033 stuff from the sources (they're covered by the config-win32.h now).
2035 - Pascal Gaudette fixed a missing ldap.c problem in the
2036 Makefile.vc6 file. He also addressed a problem in src/config-win32.h.
2038 Daniel (14 March 2000):
2039 - Paul Harrington pointed out that the 'http_code' variable in the -w output
2040 was never written. I fixed it now.
2042 - Janne Johansson reported the complaints that OpenBSD does
2043 when getdate.c #includes malloc.h. It claims stdlib.h should be included
2044 instead. I added #ifdef HAVE_MALLOC_H code in getdate.y and two checks in
2045 the configure.in for malloc.h and stdlib.h.
2049 Daniel (13 March 2000):
2050 - <curl at spam.wolvesbane.net> pointed out that the way curl sent cookies in a
2051 single line wasn't enjoyed by IIS4.0 servers. In my view, that is not what
2052 the standards say, but I added a white space between the name/value pairs to
2053 perhaps make them work better.
2055 - Added the perl check back in the configure.in again since the mkhelp.pl
2058 - Made some beautifications in the curl man page.
2060 Daniel (3 March 2000):
2061 - Jörn helped me update the config-win32.h files with HAVE_SETVBUF and
2064 Daniel (3 March 2000):
2065 - Uploaded the 6.5pre2 package.
2067 Daniel (2 March 2000):
2068 - Removed the perl-programs from the distribution, they never made many people
2069 happy and I'll still keep them available on the web.
2071 - Added the -w and -N stuff to the man page. Documented the new progress meter
2072 display in README.curl.
2074 - Jörn Hartroth, Chris <cbayliss at csc.come> and Ulf
2075 Möller from the openssl development team helped bringing me the details for
2076 fixing an OpenSSL usage flaw. It became apparent when they released openssl
2077 0.9.5 since that barfed on curl's bad behavior (not seeding a random number
2080 - Yet another option: -N/--no-buffer disables buffering in the output stream.
2081 Probably most useful for very slow transfers when you really want to get
2082 every byte curl receives within some preferred time. Andrew <tmr at gci.net>
2085 - Damien Adant mailed me his fixes for making curl compile on Ultrix.
2087 Daniel (24 February 2000):
2088 - Applied Jörn Hartroth's fixes for config-win32.h and lib/Makefile.w32.
2090 I should also make a note here, if nothing else to myself, that when using
2091 the %-syntax for variables in DOS command prompts, you must use two %-
2092 letters for each one since that is an escape letter there! Maybe I should
2093 use another letter instead!
2095 - Added more variables to -w:
2103 - Made -w@filename read the syntax from a file and -w@- reads the syntax from
2104 stdin in the good old "standard" curl way.
2106 Daniel (22 February 2000):
2107 - Released a 6.5pre1 version to get some test and user feedback.
2109 Daniel (21 February 2000):
2111 - I added the -w/--write-out flag and some variables to go with it. -w is a
2112 single string, whatever you enter there will be written out when curl has
2113 completed a successful request. There are some variable substitutions and
2114 they are specified as '%{variable}' (without the quotes). Variables that
2115 exist as of this moment are:
2117 total_time - total transfer time in seconds (with 2 decimals)
2118 size_download - total downloaded amount of bytes
2119 size_upload - total uploaded amount of bytes
2120 speed_download - the average speed of the entire download
2121 speed_upload - the average speed of the entire upload
2123 I will of course add more variables, but I need input on these and others.
2125 - It struck me that the -# progress bar will be hard to just apply on the new
2126 progress bar concept. I need some feedback on this before that'll get re-
2129 Daniel (16 February 2000):
2130 - Jörn Hartroth brought me some fixes for the progress meter and I continued
2131 working on it. It seems to work for http download, http post, ftp download
2132 and ftp upload. It should be a pretty good test it works generally good.
2134 - Still need to add the -# progress bar into the new style progress interface.
2136 - Gonna have a go at my new output option parameter next.
2138 Daniel (15 February 2000):
2139 - The progress meter stuff is slowly taking place. There's more left before it
2140 is working ok and everything is tested, but we're reaching there. Slowly!
2142 Daniel (11 February 2000):
2143 - Paul Marquis fixed the config file parsing of curl to
2144 deal with any-length lines, removing the previous limit of 4K.
2146 - Eetu Ojanen's suggestion of supporting the @-style for -b
2147 is implemented. Now -b@<filename> works as well as the old style. -b@- also
2148 similarly reads the cookies from stdin.
2150 - Reminder: -D should not write to the file until it needs to, in the same way
2151 -o does. That would enable curl to use -b and -D on the same file...
2153 - Ellis Pritchard made getdate.y work for MacOS X.
2155 - Paul Harrington helped me out finding the crash in the
2156 cookie parser. He also pointed out curl's habit of sending empty cookies to
2159 Daniel (8 February 2000):
2160 - Ron Zapp corrected a problem in src/urlglob.c that
2161 prevented curl from getting compiled on sunos 4. The problem had to do
2162 with the difference in sprintf() return code types.
2164 - Transfer() should now be able to download and upload simultaneously. Let's
2165 do some progress meter fixes later this week.
2167 Daniel (31 January 2000):
2168 - Paul Harrington found another core dump in the cookie
2169 parser. Curl doesn't properly recognize the 'version' keyword and I think
2170 that is what caused this. I need to refresh some specs on cookies and see
2171 what else curl lacks to improve this a bit more once and for all.
2173 RFC 2109 clearly specifies how cookies should be dealt with when they are
2174 compliant with that spec. I don't think many servers are though...
2176 - Mark W. Eichin found that while curl is uploading a form
2177 to a web site, it doesn't read incoming data why it'll hang after a while
2178 since the socket "pipe" becomes full.
2180 It took me two hours to rewrite Download() and Upload() into the new
2181 single function Transfer(). It even seems to work! More testing is required
2182 of course... I should get the header-sending together in a kind of queue
2183 and let them get "uploaded" in Transfer() as well.
2185 - Zhibiao Wu pointed out a curl bug in the location: area,
2186 although I did not get a reproducible way to do this why I have to wait
2187 with fixing anything.
2189 - Bob Schader suggested I should implement resume
2190 support for the HTTP PUT operation, and as I think it is a valid suggestion
2193 Daniel (25 January 2000):
2194 - M Travis Obenhaus pointed out a manual mixup with -y and -Y that was
2197 - Jens Schleusener pointed out a problem to compile
2198 curl on AIX 4.1.4 and gave me a solution. This problem was already fixed
2199 by Jörn's recent #include modifications!
2201 Daniel (19 January 2000):
2202 - Oskar Liljeblad pointed out and corrected a problem
2203 in the Location: following system that made curl following a location: to a
2204 different protocol to fail.
2206 At January 31st I re-considered this fix and the surrounding source code. I
2207 could not really see that the patch did any difference, why I removed it
2208 again for further research and debugging. (It disabled location: following
2209 on server not running on default ports.)
2211 - Jörn Hartroth brought a fix that once again
2212 made it possible to select progress bar.
2214 - Jörn also fixed a few include problems.
2218 Daniel (17 January 2000):
2219 - Based on suggestions from Björn Stenberg, I made the
2220 progress deal better with larger files and added a "Time" field which shows
2221 the time spent on the download so far.
2222 - I'm now using the CVS repository on sourceforge.net, which also allows web
2223 browsing. See http://curl.haxx.nu.
2225 Daniel (10 January 2000):
2226 - Renumbered some enums in curl/curl.h since tag number 35 was used twice!
2227 - Added "postquote" support to the ftp section that enables post-ftp-transfer
2229 - Now made the -Q/--quote parameter recognize '-' as a prefix, which means
2230 that command will be issued AFTER a successful ftp transfer. This can of
2231 course be used to delete or rename a file after it has been uploaded or
2232 downloaded. Use your imagination! ;-)
2233 - Since I do the main development on solaris 2.6 now, I had to download and
2234 install GNU groff to generate the hugehelp.c file. The solaris nroff cores
2235 on the man page! So, in order to make the solaris configure script find a
2236 better result I made gnroff get checked prior to the regular nroff.
2237 - Added all the curl exit codes to the man page.
2238 - Jim Gallagher properly tracked down a bug in autoconf
2239 2.13. The AC_CHECK_LIB() macro wrongfully uses the -l flag before the -L
