10 - Jukka Pihl suggested that if (lib)curl is told to verify the peer's
11 certificate and the peer can't be verified, it should fail and return a
12 proper error code. I added a brand new error code named
13 CURLE_SSL_PEER_CERTIFICATE for this purpose.
16 - As was discussed with Frederic Lepied a while ago, I now made libcurl not
17 return error even though no data was transfered on upload/download resume
18 when the no transfer is needed. The CURLE_ALREADY_COMPLETE error was removed
19 from the header file to make any implemenator that uses that to be aware of
20 the fact that it can't be returned anymore!
22 - Improved general header-parsing to better allow white spaces and more.
24 - Rodney Simmons proved the fix I did yesterday was bad and I had to post
27 - Ingo Wilken patched away two redirect problems more!
30 - Cris Bailiff correctly noted that the space-after-header problem with
31 Location: is present on several other places in the libcurl sources.
33 - Ingo Wilken patched away a problem libcurl had when following Location:
34 headers with an extra space after the colon.
36 - Rodney Simmons found out that multiple FTP transfers did not treat relative
37 directories correctly.
40 - Getting an FTP file with CURLOPT_NOBODY set (or -I from the command line),
41 makes curl use the non-standard ftp command "SIZE". If it failed, libcurl
42 returned error. Starting now, it just don't output the file size instead.
46 - Corrected two minor compiler warnings due to the FILE * to void * conversion
47 that I missed at two places. Jörn Hartroth brought me patches. Sander Gates
48 filed a bug report on this.
53 - All callback functions now take 'void *' instead of 'FILE *'. This is made
54 this way to make it more obvious to people that anything can be passed to
55 them (by using the apropriate option). After discussions with Sterling
59 - Cris Bailiff fixed a chunked transfer encoding problem with persistent
60 connection that made libcurl fail if the persistent connection used mixed
61 chunked and non-chunked transfers.
63 - Cris Bailiff fixed a bad treatment of 304-replies, as they would not be
64 treated as content-length 0 replies but would cause a "hang" until the
65 server timed-out and closed the connection.
67 - Brad Burdick found a minor problem in the docs/examples/Makefile.am
69 Daniel (27 April 2001)
70 - Updated the INTERALS document again. It was lagging a bit. I think I made it
71 more easy to follow now as well.
73 - Brad Burdick found a problem with persistent connections when curl received
74 a "Content-Length: 0" header.
76 - Giuseppe D'Ambrosio was first out to report that TELNET doesn't work in curl
77 compiled/built on win32. It seems to work for unixes though!
79 - Dave Hamilton reported weird problems with CURL/PHP that I really can't
80 explain at the moment. I'm hoping on some help from the PHP crew.
82 Daniel (26 April 2001)
83 - I rewrote the FTP command response function. I had to do it to make ftps
84 work, as the OpenSSL read()-function didn't work the same way the normal
85 unix read() does, but it was also a huge performance boost. Previously the
86 function read one byte at a time, now it reads very large chunks, and it
87 makes a notable speed difference.
89 Daniel (25 April 2001)
90 - Connection re-use when not using a proxy didn't work properly for
91 non-default port numbers.
93 Daniel (24 April 2001)
94 - I've noticed that FTPS doesn't work. We attempt to use ssl even for the
95 data transfer, which causes the transfer to 'hang'... We need to fix this.
97 - Improved the test suite to use 'stunnel' to do HTTPS and FTPS testing on
98 the alredy written perl servers easily.
100 Daniel (23 April 2001)
101 - The OpenSSL version string recently modified didn't zero terminate one
102 of the generated strings properly, which could lead to a crash or simply
103 weird version string output!
107 Daniel (22 April 2001)
108 - Rosimildo da Silva updated the Makefiles for Borland/Windows.
110 - Eric Rautman pointed out a problem with persistent connections that would
111 lead to broken Host: headers in the second HTTP request.
113 Daniel (20 April 2001)
114 - Added man pages for the curl_strequal() and curl_mprintf() families. Wrote
115 a 'libcurl overview' man page.
117 - Spell-fixed some documents.
119 - S. Moonesamy corrected mistakes in the man page.
121 - Cris Bailiff fixed the curl_slists options in the perl interface, present
122 separately in the Curl::easy 1.1.4 package.
124 Daniel (19 April 2001)
125 - Linus Nielsen Feltzing removed the decimals from the size variables in the
126 --write-out output. We hardly ever get fraction of bytes! :-)
130 Daniel (19 April 2001)
132 - Albert Chin provided a configure patch for the AC_SYS_LARGEFILE macro.
134 Daniel (18 April 2001)
135 - Input from Michael Mealling made me add --feature to curl-config. It
136 displays a list of features that have been built-in in the current
137 libcurl. The currently available features that can be listed are: SSL, KRB4
140 - I committed Cris and Georg's perl interface work. They've got callbacks
141 working and options that receives those slist pointers.
143 - Puneet Pawaia detected a problem with resumed downloads that use persistent
144 connections and I made a rather large writeup to correct this. It is
145 important that all session-data is stored in the connectdata struct and not
146 in the main struct as this previously did.
148 Daniel (17 April 2001)
149 - Frederic Lepied fixed a ftp resumed download problem and introduced a new
150 error code that lets applications be able to detect when a resumed download
151 actually didn't download anything since the whole file is already present.
152 Should this return OK instead?
154 - I added 'curl-config.in' to the root dir and configure script. Now, a
155 curl-config script is made when curl is built. The script can be used to
156 figure out compile time options used when libcurl was built, which in turn
157 should be options YOU should use to build applications that use libcurl.
159 This *-config style is not a new idea, but something that has been used
160 successfully in other (library based) projects.
162 - Phil Karn pointed out that libcurl wrongly did not always use GMT time zone
163 for the If-Modified-Since style headers.
165 - Georg Schwarz pointed out an extra needed #include file needed in src/main.c
166 for curl to build on Ultrix.
168 Daniel (11 April 2001)
169 - Cris Bailiff pointed out two problems that I corrected. First, libcurl's use
170 of the environment variable HTTP_PROXY in uppercase may become a security
171 hazard when people use libcurl in a server/cgi situation where the server
172 sets the HTTP_*-variables according to incoming headers in the HTTP
173 request. Thus, a "Proxy:"-header would set that environment variable!
175 Then, invoking curl_easy_perform() without having an URL set caused a crash.
177 - S. Moonesamy brought a patch that make curl use non-blocking connects on
178 windows when connection timeout is set, as it allows windows users to set
181 - Hirotaka Matsuyuki wrote a Ruby interface to libcurl!
183 - Cris Bailiff, Forrest Cahoon and Georg Horn work on the Perl interface.
185 - I've written a first shot at a Java interface to libcurl. Many thanks to
186 Daniel Marell for tirelessly answering to all my basic Java questions. It
187 works, but it is still very basic.
189 Daniel (10 April 2001)
190 - The progress display could get silly when doing multiple file transfers, as
191 it wasn't properly reset between transfers!
193 - Discussions with Cris Bailiff who writes a Perl interface to libcurl, made
194 me add CURLOPT_HEADERFUNCTION. It can be used to set a separate callback
195 function for writing headers. Previously you could only set a different FILE
196 * when headers are written from within libcurl.
198 Daniel (7 April 2001)
199 - Andrés García fixed a problem in curl_escape() and pointed out a flaw in
200 the curl_easy_setopt man page.
202 Daniel (6 April 2001)
203 - Adjusted the version code to properly display OpenSSL 0.9.6a. They sure
204 change their version define format often...
206 - curl_formfree() now accepts a NULL pointer without crashing!
210 Daniel (3 April 2001)
211 - Puneet Pawaia pointed out two serious problems. Libcurl would attempt to
212 read bad memory during situations when an (ftp) connection attempt failed.
213 Also, the lib/Makefile.vc6 was corrected.
215 - More investigations in the Location: following code made me realize that
216 it was not clean enough to work transparantly with persistent and non-
217 persistent connections. I think I've fixed it now.
219 Daniel (29 March 2001)
220 - Georg Horn mailed me some corrections for the Curl::easy perl interface.
222 - Experimental ftps:// support added. It is basically FTP over SSL for the
223 control connection. It still makes all data transfers going over unencrypted
224 connections. Rainer Weikusat's ftpd-ssl server hack supports this and I used
225 that to verify the functionality.
227 Daniel (27 March 2001)
228 - Guenole Bescon discovered that if you set a CURLOPT_TIMEOUT and then tried
229 to get a file from a site and it fails, the SIGALRM would still be sent
230 after the timeout-time, quite inexpectedly!
232 - I added an ftp transfer example to docs/examples/ and I also wrote a tiny
233 example makefile that can be used as a start when building one of the
238 Daniel (26 March 2001)
239 - Mohamed Lrhazi reported problems with 7.6.1 and persistent HTTP/1.0
240 connections (when the server replied a Connection: Keep-Alive) and this
241 problem was not properly dealt with in 7.7 either. A patch was posted to the
242 curl-and-php mailing list.
244 Daniel (24 March 2001)
245 - Colin Watson reported about a problem and brought a patch that corrected it,
246 which was about the man page and lines starting with a single quote (') in a
247 way that gnroff doesn't like.
249 Daniel (23 March 2001)
250 - Peter Bray reported correctly that the root makefile used make instead of
251 $(MAKE) for the test target.
253 - Corrected the Curl::easy perl interface to use curl_easy_setopt() and not
254 curl_setopt() which was removed in 7.7!
256 - S. Moonesamy provided updates on three documents (MANUAL, INSTALL and FAQ).
258 - When following a Location:, libcurl would sometimes write to the URL string
259 in a way it shouldn't. As the pointer is passed-in to libcurl from an
260 application, we can't be allowed to write to it. The particular bug report
261 from 'nk' that brought this up was because he had a read-only URL that then
262 caused a libcurl crash!
264 - No longer reads HEAD responses longer than to the last header. Previously,
265 curl would read the full reply if the connection was a "close" one.
267 - libcurl did re-use connections way too much. Doing "curl
268 http://www.{microsoft,ibm}.com" would make it re-use the connection which
269 made the second request return very odd results.
271 Daniel (22 March 2001)
272 - Edin Kadribasic made me aware that curl should not re-send POST requests
273 when following 302-redirects. I made 302 work like 303 which means curl uses
274 GET in the following request(s).
276 - libcurl now reset the "followed-location" counter on each invoke of
277 curl_easy_perform() as it otherwise would sum up all redirects on the same
278 connection and thus could reach the maxredirs counter wrongly.
280 - Jim Drash suggested curl_escape() should not re-encode what already looks
281 like an encoded sequence and I think that's a fair suggestion.
285 Daniel (22 March 2001)
286 - The configure script now fails with an error message if gethostbyname_r() is
287 detected but it couldn't figure out how to invoke it (what amount of
288 arguments it is supposed to get). Reports from Andrés García made me aware
291 - Talking with Jim Drash made me finally put the curl_escape and curl_unescape
292 functions in the curl.h include file and write man pages for them. The
293 escape function was modified to use the same interface as the unescape one
296 - No bug reports at all on the latest betas. Release time coming up.
300 Daniel (19 March 2001)
301 - Georg Ottinger reported problems with using -C together with -L in the sense
302 that the -C info got lost when it was redirected. I could not repeat this
303 problem on the 7.7 branch why I leave this for the moment. Test case 39 was
304 added to do exactly this, and it seems to do right.
306 - Christian Robottom Reis reported how his 7.7 beta didn't successfully do
307 form posts as elegantly as 7.6.1 did. Indeed, this was a flaw in the header
308 engine, as HTTP 1.1 has introduced a new 100 "transient" return code for PUT
309 and POST operations that I need to add support for. Section 8.2.3 in RFC2616
310 has all the details. Seems to work now!
312 Daniel (16 March 2001)
313 - After having experienced another machine break-down, we're back.
315 - Georg Horn's perl interface Curl::easy is now included in the curl release
316 archive. The perl/ directory is now present. Please help me with docs,
317 examples and updates you think fit.
319 - Made a new php/ directory in the release archive and moved the PHP examples
320 into a subdirectory in there. Not much PHP info yet, but I plan to. Please
321 help me here as well!
323 - Made libcurl return error if a transfer is aborted in the middle of a
324 "chunk". It actually enables libcurl to discover premature transfer aborts
325 even if the Content-Length: size is unknown.
327 Daniel (15 March 2001)
328 - Added --connect-timeout to curl, which sets the new CURLOPT_CONNECTTIMEOUT
329 option in libcurl. It limits the time curl is allowed to spend in the
330 connection phase. This differs from -m/--max-time that limits the entire
331 file transfer operation. Requested by Larry Fahnoe and others.
333 I also updated the curl.1 and curl_easy_setopt.3 man pages and removed the
338 Daniel (14 March 2001)
339 - Made curl grok IPv6 with HTTP proxies and got everything to compile nicely
340 again when ENABLE_IPV6 is set.
342 I need to remake things in the test suite. I can't test the FTP parts with
343 curl built for IPv6 as it uses a different set of FTP commands then!
345 - I fell onto a bug report on php.net (posted by Lars Torben Wilson) that was
346 a report meant for our project. Anyway, it said the .netrc parsing didn't
347 work as supposed, and as I agreed with Lars, I made the netrc parser use
348 getpwuid() to figure out the home directory of the effective user and try
349 that netrc. It still uses the environment variable HOME for those that don't
350 have that function or if the user doesn't return valid pwd info.
352 - Edin Kadribaic posted a bug report where he got a crash when a fetch with
353 user+password in the URL followed a Location: to a second URL (absolute,
354 without name+password). This bug has been around for a long while and
355 crashes due to a read at address zero. Fixed now. Wrote test case 38, that
358 - Modified the test suite's httpserver slightly to append all client request
359 data to its log file so that the test script now better can verify a range
360 of requests and not only the last one, as it did previously.
362 - Updated the curl man page with --random-file and --egd-file details.
366 Daniel (14 March 2001)
367 - Björn Stenberg provided similar fixes as Jörn did and some additional patches
368 for non-SSL compiles.
370 - I increased the interface number for libcurl as I've removed the low level
371 functions from the interface. I also took this opportunity to rename the
372 Curl_strequal function to curl_strequal and Curl_strnequal to
373 curl_strnequal, as they're public libcurl functions (even if they're still
376 This will make older programs not capable of using the new libcurl with
377 just a drop-in replacement.
379 - Jörn Hartroth updated stuff for win32 compiles:
380 o config-win32.h was fixed for socklen_t
381 o lib/ssluse.c had a bad #endif placement
382 o lib/file.c was made to compile on win32 again
383 o lib/Makefile.m32 was updated with the new files
384 o lib/libcurl.def matches the current interface state
386 Daniel (13 March 2001)
387 - It only took an hour or so before Jörn Hartroth found a problem in the
388 chunked transfer-encoding. Given his fine example-site, I could easily spot
389 the problem and when I re-read the spec (the part I have pasted in the top
390 of the http_chunks.h file), I realized I had made my state-machine slightly
391 wrong and didn't expect/handle the trailing CRLF that comes after the data
392 in each chunk (and those extra two bytes sure feel wasted).
394 Had to modify test case 34 to match this as well.
398 Daniel (13 March 2001)
399 - Added the policy stuff to the curl_easy_setopt man page for the two supported
402 - Implemented some support for the CURLOPT_CLOSEPOLICY option. The policies
403 CURLCLOSEPOLICY_LEAST_RECENTLY_USED and CURLCLOSEPOLICY_OLDEST are now
404 supported, and the "least recently used" is used as default if no policy
407 Daniel (12 March 2001)
408 - Added CURLOPT_RANDOM_FILE and CURLOPT_EGDSOCKET to libcurl for seeding the
409 SSL random engine. The random seeding support was also brought to the curl
410 client with the new options --random-file <file> and --egd-file <file>. I
411 need some people to really test this to know they work as supposed. Remember
412 that libcurl now informs (if verbose is on) if the random seed is considered
413 weak (HTTPS connections).
415 - Made the chunked transfer-encoding engine detected bad formatted data length
416 and return error if so (we can't possibly extract sensible data if this is
417 the case). Added a test case that detects this. Number 36. Now there are 60
420 - Added 5 new libcurl options to curl/curl.h that can be used to control the
421 persistent connection support in libcurl. They're also documented (fairly
422 thoroughly) in the curl_easy_setopt.3 man page. Three of them are now
423 implemented, although not really tested at this point... Anyway, the new
424 implemented options are named CURLOPT_MAXCONNECTS, CURLOPT_FRESH_CONNECT,
425 CURLOPT_FORBID_REUSE. The ones still left to write code for are:
426 CURLOPT_CLOSEPOLICY and its related option CURLOPT_CLOSEFUNCTION.
428 - Made curl (the actual command line tool) use the new libcurl 7.7 persistent
429 connection support by re-using the same curl handle for every specified file
430 transfer and after some more test case tweaking we have 100% test case OK.
431 I made some test cases return HTTP/1.0 now to make sure that works as well.
433 - Had to add 'Connection: close' to the headers of a bunch of test cases so
434 that curl behaves "old-style" since the test http server doesn't do multiple
435 connections... Now I get 100% test case OK.
437 - The curl.haxx.se site, the main curl mailing list and my personal email are
438 all dead today due to power blackout in the area where the main servers are
441 - I've made persistance work over a squid HTTP proxy. I find it disturbing
442 that it uses headers that aren't present in any HTTP standard though
443 (Proxy-Connection:) and that makes me feel that I'm now on the edge of what
444 the standard actually defines. I need to get this code excercised on a lot
445 of different HTTP proxies before I feel safe.
447 Now I'm facing the problem with my test suite servers (both FTP and HTTP)
448 not supporting persistent connections and libcurl is doing them now. I have
449 to fix the test servers to get all the test cases do OK.
451 Daniel (8 March 2001)
452 - Guenole Bescon reported that libcurl did output errors to stderr even if
453 MUTE and NOPROGRESS was set. It turned out to be a bug and happens if
454 there's an error and no ERRORBUFFER is set. This is now corrected.
458 Daniel (8 March 2001)
459 - "Transfer-Encoding: chunked" is no longer any trouble for libcurl. I've
460 added two source files and I've run some test downloads that look fine.
462 - HTTP HEAD works too, even on 1.1 servers.
464 Daniel (5 March 2001)
465 - The current 57 test cases now pass OK. It would suggest that libcurl works
466 using the old-style with one connection per handle. The test suite doesn't
467 handle multiple connections yet so there are no test cases for this.
469 - I patched the telnet.c heavily to not use any global variables anymore. It
470 should make it a lot nicer library-wise.
472 - The file:// support was modified slightly to use the internal connect-first-
475 Daniel (4 March 2001)
480 Daniel (4 March 2001)
481 - Now, there's even a basic check that a re-used connection is still alive
482 before it is assumed so. A few first tests have proven that libcurl will
483 then re-connect instead of re-use the dead connection!
485 Daniel (2 March 2001)
486 - Now they work intermixed as well. Major coolness!
488 - More fiddling around, my 'tiny' client I have for testing purposes now has
489 proved to download both FTP and HTTP with persistent connections. They do
490 not work intermixed yet though.
492 Daniel (1 March 2001)
493 - Wilfredo Sanchez pointed out a minor spelling mistake in a man page and that
494 curl_slist_append() should take a const char * as second argument. It does
497 Daniel (22 February 2001)
498 - The persistent connections start to look good for HTTP. On a subsequent
499 request, it seems that libcurl now can pick an already existing connection
500 if a suitable one exists, or it opens a new one.
502 - Douglas R. Horner mailed me corrections to the curl_formparse() man page
505 Daniel (20 February 2001)
506 - Added the docs/examples/win32sockets.c file for our windows friends.
508 - Linus Nielsen Feltzing provided brand new TELNET functionality and
511 * Negotiation is now passive. Curl does not negotiate until the peer does.
512 * Possibility to set negotiation options on the command line, currently only
513 XDISPLOC, TTYPE and NEW_ENVIRON (called NEW_ENV).
514 * Now sends the USER environment variable if the -u switch is used.
515 * Use -t to set telnet options (Linus even updated the man page, awesome!)
517 - Haven't done this big changes to curl for a while. Moved around a lot of
518 struct fields and stuff to make multiple connections get connection specific
519 data in separate structs so that they can co-exist in a nice way. See the
520 mailing lists for discussions around how this is gonna be implemented. Docs
521 and more will follow.
523 Studied the HTTP RFC to find out better how persistent connections should
524 work. Seems cool enough.
526 Daniel (19 February 2001)
527 - Bob Schader brought me two files that help set up a MS VC++ libcurl project
528 easier. He also provided me with an up-to-date libcurl.def file.
530 - I moved a bunch of prototypes from the public <curl/curl.h> file to the
531 library private urldata.h. This is because of the upcoming changes. The
532 low level interface is no longer being planned to become reality.
534 Daniel (15 February 2001)
535 - CURLOPT_POST is not required anymore. Just setting the POST string with
536 CURLOPT_POSTFIELDS will switch on the HTTP POST. Most other things in
537 libcurl already works this way, i.e they require only the parameter to
538 switch on a feature so I think this works well with the rest. Setting a NULL
539 string switches off the POST again.
541 - Excellent suggestions from Rich Gray, Rick Jones, Johan Nilsson and Bjorn
542 Reese helped me define a way how to incorporate persistent connections into
543 libcurl in a very smooth way. If done right, no change may have to be made
544 to older programs and they will just start using persistent connections when
547 Daniel (13 February 2001)
548 - Changed the word 'timeouted' to 'timed out' in two different error messages.
549 Suggested by Larry Fahnoe.
553 Daniel (9 February 2001)
554 - Frank Reid and Cain Hopwood provided information and research around a HTTPS
555 PUT/upload problem we seem to have. No solution found yet.
557 Daniel (8 February 2001)
558 - An interesting discussion is how to specify an empty password without having
559 curl ask for it interactively? The current implmentation takes an empty
560 password as a request for a password prompt. However, I still want to
561 support a blank user field. Thus, today if you enter "-u :" (without user
562 and password) curl will prompt for the password. Tricky. How would you
563 specify you want the prompt otherwise?
565 - Made the netrc parse result possible to use for other protocols than FTP and
566 HTTP (such as the upcoming TELNET fixes).
568 - The previously mentioned "MSVC++ problems" turned out to be a non-issue.
570 - Added a HTTP file upload code example in the docs/examples/ section on
573 - Adjusted the FTP response fix slightly.
577 Daniel (7 February 2001)
578 - S. Moonesamy found a flaw in the response reading function for FTP that
579 could make libcurl not get out of the loop properly when it should, if
580 libcurl got -1 returned when reading the socket.
582 - I found a similar mistake in http.c when using a proxy and reading the
583 results from the proxy connection.
585 Daniel (6 February 2001)
586 - S. Moonesamy pointed out that the VC makefile in src/ needed the libpath set
587 for the debug build to work.
589 - Daniel Gehriger stepped in to assist with the VC++ stuff Robert Weaver
590 brought up yesterday.
592 Daniel (5 February 2001)
593 - Jun-ichiro itojun Hagino brought a big patch that brings IPv6-awareness to
594 a bunch of different areas within libcurl.
596 - Robert Weaver told me about the problems the MS VC++ 6.0 compiler has with
597 the 'static' keyword on a number of libcurl functions. I might need to add a
598 patch that redefines static when libcurl is compiled with that compiler.
599 How do I know when VC++ compiles, anyone?
601 Daniel (4 February 2001)
602 - curl_getinfo() was extended with two new options:
603 CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD. They
604 return the full assumed content length of the transfer in the given
605 direction. The CURLINFO_CONTENT_LENGTH_DOWNLOAD will be the Content-Length:
606 size of a HTTP download. Added descriptions to the man page as well. This
607 was done after discussions with Bob Schader.
609 Daniel (3 February 2001)
610 - Ingo Ralf Blum provided another fix that makes curl build under the more
611 recent cygwin installations. It seems they've changed the preset defines to
612 not include WIN32 anymore.
616 Daniel (31 January 2001)
617 - Curl_read() and curl_read() now return a ssize_t for the size, as it had to
618 be able to return -1. The telnet support crashed due to this and there was a
619 possibility to weird behaviour all over. Linus Nielsen Feltzing helped me
622 - Added a configure.in check for a working getaddrinfo() if IPv6 is requested.
623 I also made the configure script feature --enable-debug which sets a couple
624 of compiler options when used. It assumes gcc.
626 Daniel (30 January 2001)
627 - I finally took a stab at the long-term FIXME item I've had on myself, and
628 now libcurl will properly work when doing a HTTP range-request that follows
629 a Location:. Previously that would make libcurl fail saying that the server
630 doesn't seem to support range requests.
632 Daniel (29 January 2001)
633 - I added a test case for the HTTP PUT resume thing (test case 33).
637 Daniel (29 January 2001)
638 - Yet another Content-Range change. Ok now? Bob Schader checks from his end
639 and it works for him.
641 Daniel (27 January 2001)
642 - So the HTTP PUT resume fix wasn't good. There should appearantly be a
643 Content-Range header when resuming a PUT.
645 - I noticed I broke the download-check that verifies that a resumed HTTP
646 download is actually resumed. It got broke because my new 'httpreq' field
647 in the main curl struct. I should get slapped. I added a test case for
648 this now, so I won't be able to ruin this again without noticing.
650 - Added a test case for content-length verifying when downloading HTTP.
652 - Made the progress meter title say if the transfer is being transfered. It
653 makes the output slightly better for resumes.
655 - When dealing with Location: and HTTP return codes, libcurl will not attempt
656 to follow the spirit of RFC2616 better. It means that when POSTing to a
657 URL that is being following to a second place, the standard will judge on
658 what to do. All HTTP codes except 303 and 305 will cause curl to make a
659 second POST operation. 303 will make a GET and 305 is not yet supported.
661 I also wrote two test cases for this POST/GET/Location stuff.
665 Daniel (26 January 2001)
666 - Lots of mails back and forth with Bob Schader finally made me add a small
667 piece of code in the HTTP engine so that HTTP upload resume works. You can
668 now do an operation like 'curl -T file -C <offset> <URL>' and curl will PUT
669 the ending part of the file starting at given offet to the specified URL.
673 Daniel (25 January 2001)
674 - I took hold of Rick Jones' question why we don't use recv() and send() for
675 reading/writing to the sockets and I've now modified the sread() and
676 swrite() macros to use them instead. If nothing else, they could be tested
677 in the next beta-round coming right up.
679 - Jeff Morrow found a problem with libcurl's usage of SSL_read() and supplied
680 his research results in how to fix this. It turns out we have to invoke the
681 function several times in some cases. The same goes for the SSL_write().
683 I made some rather drastic changes all over libcurl to make all writes and
684 reads get done on one single place so that this repeated-attempts thing
685 would only have to be implemented at one point.
687 - Rick Jones spotted that the 'total time' counter really didn't measure the
688 total time very accurate on subsecond levels.
690 - Johan Nilsson pointed out the need to more clearly specify that the timeout
691 value you set for a download is for the *entire* download. There's currently
692 no option available that sets a timeout for the connection phase only.
694 Daniel (24 January 2001)
695 - Ingo Ralf Blum submitted a series of patches required to get curl to compile
696 properly with cygwin.
698 - Robert Weaver posted a fix for the win32 section of the curl_getenv() code
699 that corrected a potential memory leak.
701 - Added comments in a few files in a sudden attempt to make the sources more
702 easy to read and understand!
704 Daniel (23 January 2001)
705 - Added simple IPv6 detection in the configure script and made the version
706 string add 'ipv6' to the enable section in that case. ENABLE_IPV6 will be
707 set if curl is compiled with IPv6 support enabled.
709 - Added a parser for IPv6-style specified IP-addresses in a URL. Thus, when
710 IPv6 gets enabled soon, we can use URLs like '[0::1]:80'...
712 - Made the URL globbing in the client possible to fail silently if there's an
713 error in the globbing. It makes it almost intuitive, so when you don't
714 follow the syntax rules, globbing is simply switched off and the raw string
717 I still think we'll get problems with IPv6-style IP-addresses when we *want*
718 globbing on parts of the URL as the initial part of the URL will for sure
719 seriously confuse the globber.
721 Daniel (22 January 2001)
722 - Björn Stenberg supplied a progress meter patch that makes it look better even
723 during slow starts. Previously it made some silly assumptions...
725 - Added two FTP tests for -Q and -Q - stuff since it was being discussed on
726 the mailing list. Had to correct the ftpserver.pl too as it bugged slightly.
728 Daniel (19 January 2001)
729 - Made the Location: parsers deal with any-length URLs. Thus I removed the last
730 code that restricts the length of URLs that curl supports.
732 - Added a --globoff test case (#28) and it quickly identified a memory problem
733 in src/main.c that I took care of.
737 Daniel (17 January 2001)
738 - Made the two former files lib/download.c and lib/highlevel.c become the new
739 lib/transfer.c which makes more sense. I also did the rename from Transfer()
740 to Curl_Transfer() in the other source files that use the transfer function
741 in the spirit of using Curl_ prefix for library-scoped global symbols.
743 Daniel (11 January 2001)
744 - Added -g/--globoff that switches OFF the URL globbing and thus enables {}[]
745 letters to be part of the URL. Do note that RFC2396 section 2.4.3 explicitly
746 mention these letters to be escaped. This was posted as a feature request by
747 Jorge Gutierrez and as a bug by Terry.
749 - Short options to curl that requires parameters can now be specified without
750 having the option and its parameter space separated. -ofile works as good as
751 -o file. -m20 is equal to -m 20. Do note that this goes for single-letter
752 options only, verbose --long-style options still must be separated with
753 space from their parameters.
755 Daniel (8 January 2001)
756 - Francis Dagenais reported that the SCO compiler still fails when compiling
757 curl due to that getpass_r() prototype. I've now put it around #ifndef
758 HAVE_GETPASS_R in an attempt to please the SCO systems.
760 - Made some minor corrections to get the client to cleanup properly and I made
761 the separator work again when getting multiple globbed URLs to stdout.
763 - Worked with Loic Dachary to get the make dist and make distcheck work
764 correctly. The 'maketgz' script is now using the automake generated 'make
765 dist' when creating release archives. Loic successfully made 'make rpms'
766 automatically build RPMs!
768 Loic Dachary (6 January 2001)
769 - Automated generation of rpm packages, no need to be root.
771 - make distcheck generates a proper distribution (EXTRA_DIST
772 in all Makefile.am modified to match FILES).
774 Daniel (5 January 2001)
775 - Huge client-side hack: now multiple URLs are supported. Any number of URLs
776 can be specified on the command line, and they'll all be downloaded. There
777 must be a corresponding -o or -O for each URL or the data will be written to
778 stdout. This needs more testing, time to release a 7.6-pre package.
780 - The krb4 support was broken in the release. Fixed now.
782 - Huge internal symbol rename operation. All non-static but still lib-internal
783 symbols should now be prefixed with 'Curl_' to prevent collisions with other
784 libs. All public symbols should be prefixed with 'curl_' and the rest should
785 be static and thus invisible to the outside world. I updated the INTERNALS
786 document to say this as well.
790 Daniel (4 January 2001)
791 - As Kevin P Roth suggested, I've added text to the man page for every command
792 line option and what happens when you specify that option more than
793 once. That hasn't been exactly crystal clear before.
795 - Made the configure script possible to run from outside the source-tree. For
796 odd reasons I can't build curl properly outside though. It has to do with
797 curl's dependencies on libcurl...
799 - Cut off all older (dated 1999 and earlier) CHANGES entries from this file.
800 The older piece is named CHANGES.0 and is added to the CVS repository in
801 case anyone would need it.
803 - I added another file 'CVS-INFO' to the CVS. It contains information about
804 files in the CVS that aren't included in release archives and how to build
805 curl when you get the sources off CVS.
807 - Updated CONTRIBUTE and FAQ due to the new license.
809 Daniel (3 January 2001)
810 - Renamed README.libcurl to LIBCURL
812 - Changed headers in all sources files to the new dual license concept of
813 curl: use the MIT/X derivate license *or* MPL. The LEGAL file was updated
814 accordingly and the MPL 1.1 and MIT/X derivate licenses are now part of the
817 Daniel (30 December 2000)
818 - Made all FTP commands get sent with the trailing CRLF in one single write()
819 as splitting them up seems to confuse at least some firewalls (FW-1 being
822 Daniel (19 December 2000)
823 - Added file desrciptor and FILE handle leak detection to the memdebug system
824 and thus I found and removed a file descriptor leakage in the ftp parts
825 that happened when you did PORTed downloads.
827 - Added an include <stdio.h> in <curl/curl.h> since it uses FILE *.
829 Daniel (12 December 2000)
830 - Multiple URL downloads with -O was still bugging. Not anymore I think or
831 hope, or at least I've tried... :-O
833 - Francois Petitjean fixed another -O problem
837 Daniel (11 December 2000)
838 - Cleaned up a few of the makefiles to use unix-style newlines only. As Kevin
839 P Roth found out, at least one CVS client behaved wrongly when it found
840 different newline conventions within the same file.
842 - Albert Chin-A-Young corrected the LDFLAGS use in the configure script for
845 Daniel (6 December 2000)
846 - Massimo Squillace correctly described how libcurl could use session ids when
847 doing SSL connections.
849 - James Griffiths found out that curl would crash if the file you specify with
850 -o is shorter than the URL! This took some hours to fully hunt down, but it
853 Daniel (5 December 2000)
854 - Jaepil Kim sent us makefiles that build curl using the free windows borland
855 compiler. The root makefile now accepts 'make borland' to build curl with
858 - Stefan Radman pointed out that the test makefiles didn't use the PERL
859 variable that the configure scripts figure out. Actually, you still need
860 perl in the path for the test suite to run ok.
862 - Rich Gray found numerous portability problems:
863 * The SCO compiler got an error on the getpass_r() prototype in getpass.h
864 since the curl one differed from the SCO one
865 * The HPUX compiler got an error because of how curl did the sigaction
866 stuff and used a define HPUX doesn't have (or need).
867 * A few more problems remain to be researched.
869 - Paul Harrington experienced a core dump using https. Not much details yet.
871 Daniel (4 December 2000)
872 - Jörn Hartroth fixed a problem with multiple URLs and -o/-O.
876 Daniel (1 December 2000)
877 - Craig Davison gave us his updates on the VC++ makefiles, so now curl should
878 build fine with the Microsoft compiler on windows too.
880 - Fixed the libcurl versioning so that we don't ruin old programs when
881 releasing new shared library interfaces.
883 Daniel (30 November 2000)
884 - Renamed docs/README.curl to docs/MANUAL to better reflect what the document
887 Daniel (29 November 2000)
888 - I removed a bunch of '#if 0' sections from the code. They only make things
889 harder to follow. After all, we do have all older versions in the CVS.
893 Daniel (28 November 2000)
894 - I filled in more error codes in the man page error code list that had been
897 - James Griffiths mailed me a fine patch that introduces the CURLOPT_MAXREDIRS
898 libcurl option. When used, it'll prevent location following more than the
899 set number of times. It is useful to break out of endless redirect-loops.
901 Daniel (27 November 2000)
902 - Added two test cases for file://.
904 Daniel (22 November 2000)
905 - Added the libcurl CURLOPT_FILETIME setopt, when set it tries to get the
906 modified time of the remote document. This is a special option since it
907 involves an extra set of commands on FTP servers. (Using the MDTM command
908 which is not in the RFC959)
910 curl_easy_getinfo() got a corresponding CURLINFO_FILETIME to get the time
911 after a transfer. It'll return a zero if CURLOPT_FILETIME wasn't used or if
912 the time wasn't possible to get.
914 --head/-I used on a FTP server will now present a 'Last-Modified:' header
915 if curl could get the time of the specified file.
917 - Added the option '--cacert [file]' to curl, which allows a specified PEM
918 file to be used to verify the peer's certificate when doing HTTPS
919 connections. This has been requested, rather recently by Hulka Bohuslav but
920 others have asked for it before as well.
922 Daniel (21 November 2000)
923 - Numerous fixes the test suite has brought into the daylight:
925 * curl_unescape() could return a too long string
926 * on ftp transfer failures, there could be memory leaks
927 * ftp CWD could use bad directory names
928 * memdebug now uses the mprintf() routines for better portability
929 * free(NULL) removed when doing resumed transfers
931 - Added a bunch of test cases for FTP.
933 - General cleanups to make less warnings with gcc -Wall -pedantic.
935 - I made the tests/ftpserver.pl work with the most commonly used ftp
936 operations. PORT, PASV, RETR, STOR, LIST, SIZE, USER, PASS all work now. Now
937 all I have to do is integrate the ftp server doings in the runtests.pl
938 script so that ftp tests can be run the same way http tests already run.
940 Daniel (20 November 2000)
941 - Made libcurl capable of dealing with any-length URLs. The former limit of
942 4096 bytes was a bit annoying when people wanted to use curl to really make
943 life tough on a web server. Now, the command line limit is the most annoying
944 but that can be circumvented by using a config file.
946 NOTE: there is still a 4096-byte limit on URLs extracted from Location:
949 - Corrected the spelling of 'resolve' in two error messages.
951 - Alexander Kourakos posted a bug report and a patch that corrected it! It
952 turned out that lynx and wget support lowercase environment variable names
953 where curl only looked for the uppercase versions. Now curl will use the
954 lowercase versions if they exist, but if they don't, it'll use the uppercase
957 Daniel (17 November 2000)
958 - curl_formfree() was added. How come no one missed that one before? I ran the
959 test suite with the malloc debug enabled and got lots of "nice" warnings on
960 memory leaks. The most serious one was this. There were also leaks in the
961 cookie handling, and a few errors when curl failed to connect and similar
962 things. More tests cases were added to cover up and to verify that these
963 problems have been removed.
965 - Mucho updated config file parser (I'm dead tired of all the bug reports and
966 weird behaviour I get on the former one). It works slightly differently now,
967 although I doubt many people will notice the differences. The main
968 difference being that if you use options that require parameters, they must
969 both be specified on the same line. With this new parser, you can also
970 specify long options without '--' and you may separate options and
971 parameters with : or =. It makes a config file line could look like:
973 user-agent = "foobar and something"
975 Parameters within quotes may contain spaces. Without quotes, they're
976 expected to be a single non-space word.
978 Had to patch the command line argument parser a little to make this work.
980 - Added --url as an option to allow the URL to be specified this way. It makes
981 way nicer config files. The previous way of specifying URLs in the config
982 file doesn't work anymore.
984 Daniel (15 November 2000)
985 - Using certain characters in usernames or passwords for HTTP authentication
986 failed. This was due to the mprintf() that had a silly check for letters,
987 and if they weren't isprint() they weren't outputed "as-is". This caused
988 passwords and usernames using '§' (for example) to fail.
992 Daniel (15 November 2000)
993 - 'tests/runtests.pl' now sorts the test cases properly when 'all' is used.
995 Daniel (14 November 2000)
996 - I fell over the draft-ietf-ftpext-mlst-12.txt Internet Draft titled
997 "Extensions to FTP" that contains a defined way how the ftp command SIZE
998 could be assumed to work.
1000 - Laurent Papier posted a bug report about using "-C -" and FTP uploading a
1001 file that isn't prsent on the server. The server might then return a 550 and
1002 curl will fail. Should it instead as Laurent Papier suggests, start
1003 uploading from the beginning as a normal upload?
1005 Daniel (13 November 2000)
1006 - Fixed a crash with the followlocation counter.
1008 - While writing test cases for the test suite, I discovered an old limitation
1009 that prevented -o and -T to be used at the same time. I removed this
1010 immediately as this has no relevance in the current libcurl.
1012 - Chris Faherty fixed a free-twice problem in lib/file.c
1014 - I fixed the perl http server problem in the test suite.
1018 Daniel (10 November 2000)
1019 - I've (finally) started working on the curl test suite. It is in the new
1020 tests/ directory. It requires sh and perl. There's a TCP server in perl and
1021 most of the other stuff running a pretty simple shell script.
1023 I've only made four test cases so far, but it proves the system can work.
1025 - Laurent Papier noticed that curl didn't set TYPE when doing --head checks
1026 for sizes on FTP servers. Some servers seem to return different sizes
1027 depending on whether ASCII or BINARY is used!
1029 - Laurent Papier detected that if you appended a FTP upload and everything was
1030 already uploaded, curl would hang.
1032 - Angus Mackay's getpass_r() in lib/getpass.c is now compliant with the
1033 getpass_r() function it seems some systems actually have.
1035 - Venkataramana Mokkapati detected a bug in the cookie parser and corrected
1036 it. If the cookie was set for the full host name (domain=full.host.com),
1037 the cookie was never sent back because of a faulty length comparison between
1038 the set domain length and the current host name.
1040 Daniel (9 November 2000)
1041 - Added a configure check for gethostbyname in -lsocket (OS/2 seems to need
1042 it). Added a check for RSAglue/rsaref for the cases where libcrypto is found
1043 but libssl isn't. I haven't verified this fix yet though, as I have no
1044 system that requires those libs to build.
1048 Daniel (7 November 2000)
1049 - Removed perror() outputs from getpass.c. Angus Mackay also agreed to a
1050 slightly modified license of the getpass.c file as the prototype was changed.
1052 Daniel (6 November 2000)
1053 - Added possibility to set a password callback to use instead of the built-in.
1054 They're controled with curl_easy_setopt() of course, the tags are
1055 CURLOPT_PASSWDFUNCTION and CURLOPT_PASSWDDATA.
1057 - Used T. Bharath's thinking and fixed the timers that showed terribly wrong
1058 times when location: headers were followed.
1060 - Emmanuel Tychon discovered that curl didn't really like user names only in
1061 the URL. I corrected this and I also fixed the since long living problem
1062 with URL encoded user names and passwords in the URLs. They should work now.
1064 Daniel (2 November 2000)
1065 - When I added --interface, the new error code that was added with it was
1066 inserted in the wrong place and thus all error codes from 35 and upwards got
1067 increased one step. This is now corrected, we're back at the previous
1068 numbers. All new exit codes should be added at the end.
1070 Daniel (1 November 2000)
1071 - Added a check for signal() in the configure script so that if sigaction()
1072 isn't present, we can use signal() instead.
1074 - I'm having a license discussion going on privately. The issue is yet again
1075 GPL-licensed programs that have problems with MPL. I am leaning towards
1076 making a kind of dual-license that will solve this once and for all...
1078 Daniel (31 October 2000)
1079 - Added the packages/ directory. I intend to let this contain some docs and
1080 templates on how to generate custom-format packages for various platforms.
1081 I've now removed the RPM related curl.spec files from the archive root.
1083 Daniel (30 October 2000)
1084 - T. Bharath brought a set of patches that bring new functionality to
1085 curl_easy_getinfo() and curl_easy_setopt(). Now you can request peer
1086 certificate verification with the *setopt() CURLOPT_SSL_VERIFYPEER option
1087 and then use the CURLOPT_CAINFO to set the certificate to verify the remote
1088 peer against. After an such an operation with a verification request, the
1089 *_getinfo() option CURLINFO_SSL_VERIFYRESULT will return information about
1090 whether the verification succeeded or not.
1092 Daniel (27 October 2000)
1093 - Georg Horn brought us a splendid patch that solves the long-standing
1094 annoying problem with timeouts that made curl exit with silly exit codes
1095 (which as been commented out lately). This solution is sigaction() based and
1096 of course then only works for unixes (and only those unixes that actually
1097 have the sigaction() function).
1099 Daniel (26 October 2000)
1100 - Björn Stenberg supplied a patch that fixed the flaw mentioned by Kevin Roth
1101 that made the password get echoed when prompted for interactively. The
1102 getpass() function (now known as my_getpass()) was also fixed to not use any
1103 static buffers. This also means we cannot use the "standard" getpass()
1104 function even for those systems that have it, since it isn't thread-safe.
1106 - Kevin Roth found out that if you'd write a config file with '-v url', the
1107 url would not be used as "default URL" as documented, although if you wrote
1108 it 'url -v' it worked! This has been corrected now.
1110 - Kevin Roth's idea of using multiple -d options on the same command line was
1111 just brilliant, and I couldn't really think of any reason why we shouldn't
1112 support it! The append function always append '&' and then the new -d
1113 chunk. This enables constructs like the following:
1115 curl -d name=daniel -d age=unknown foobarsite.com
1117 Daniel (24 October 2000)
1118 - I fixed the lib/memdebug.c source so that it compiles on Linux and other
1119 systems. It will be useful one day when someone else but me wants to run the
1120 memory debugging system.
1122 Daniel (23 October 2000)
1123 - I modified the maketgz and configure scripts, so that the configure script
1124 will fetch the version number from the include/curl/curl.h header files, and
1125 then the maketgz doesn't have to rebuild the configure script when I build
1128 - Björn Stenberg and Linus Nielsen correctly pointed out that curl was silly
1129 enough to not allow @-letters in passwords when they were specified with the
1130 -u or -U flags (CURLOPT_USERPWD and CURLOPT_PROXYUSERPWD). This also
1131 suggests that curl probably should url-decode the password piece of an URL
1132 so that you could pass an encoded @-letter there...
1134 Daniel (20 October 2000)
1135 - Yet another http server barfed on curl's request that include the port
1136 number in the Host: header always. I now only include the port number if it
1137 isn't the default (80 for HTTP, 443 for HTTPS). www.perl.com turned out to
1138 run one of those nasty servers.
1140 - The PHP4 module for curl had problems with referer that seems to have been
1141 corrected just yesterday. (Sterling Hughes of the PHP team confirmed this)
1143 Daniel (17 October 2000)
1144 - Vladimir Oblomov reported that the -Y and -y options didn't work. They
1145 didn't work for me either. This once again proves we should have that test
1148 - I finally changed the error message libcurl returns if you try a https://
1149 URL when the library wasn't build with SSL enabled. It will now return this
1151 "libcurl was built with SSL disabled, https: not supported!"
1153 I really hope it will make it a bit clearer to users where the actual
1158 Daniel (16 October 2000)
1159 - I forgot to remove some of the malloc debug defines from the makefiles in
1160 the release archive (of course).
1164 Daniel (16 October 2000)
1165 - The buffer overflow mentioned below was posted to bugtraq on Friday 13th.
1167 Daniel (12 October 2000)
1168 - Colin Robert Phipps elegantly corrected a buffer overflow. It could be used
1169 by an evil ftp server to crash curl. I took the opportunity of replacing a
1170 few other sprintf()s into snprintf()s as well.
1172 Daniel (11 October 2000)
1173 - Found some more memory leaks. This new simple memory debugger has turned out
1178 Daniel (9 October 2000)
1179 - Florian Koenig pointed out that the bool typedef in the curl/curl.h include
1180 file was breaking PHP 4.0.3 compiling. The bool typedef is not used in the
1181 public interface and was wrongly inserted in that header file.
1183 - Jörg Hartroth corrected a minor memory leak in the src/urlglob.c stuff. It
1184 didn't harm anyone since the memory is free()ed on exit anyway.
1186 - Corrected the src/main.c. We use the _MPRINTF_REPLACE #define to use our
1187 libcurl-printf() functions. This gives us snprintf() et al on all
1188 platforms. I converted the allocated useragent string to one that uses a
1191 - I've set an #if 0 section around the Content-Transfer-Encoding header
1192 generated in lib/formdata.c. This will hopefully make curl do more
1193 PHP-friendly multi-part posts.
1197 Daniel (9 October 2000)
1198 - Nico Baggus found out that curl's ability to force a ASCII download when
1199 using FTP was no longer working! I corrected this. This problem was probably
1200 introduced when I redesigned libcurl for version 7.
1202 - Georg Horn provided a source example that proved a memory leak in libcurl.
1203 I added simple memory debugging facilities and now we can make libcurl log
1204 all memory fiddling functions. An additional perl script is used to analyze
1205 the output logfile and to match malloc()s with free()s etc. The memory leak
1206 Georg found turned out to be the main cookie struct that cookie_cleanup()
1207 didn't free! The perl script is named memanalyze.pl and it is available in
1208 the CVS respository, not in the release archive.
1210 Daniel (8 October 2000)
1211 - Georg Horn found a GetHost() problem. It turned out it never assigned the
1212 pointer in the third argument properly! This could make a crash, or at best
1217 Daniel (6 October 2000)
1218 - Is the -F post following the RFC 1867 spec? We had this dicussion on the
1219 mailing list since it appears curl can't post -F form posts to a PHP
1220 receiver... I've been in touch with the PHP developers about this.
1222 - Domenico Andreoli found out that the long option '--proxy' wasn't working
1223 anymore! The option parser got confused when I added the --proxytunnel for
1224 7.3. This was indeed a very old flaw that hasn't turned up until now...
1226 - Jörn Hartroth provided patches, updated makefiles and two new files for DLL
1227 stuff on win32. He also pointed out that lib source files were compiled with
1228 -I../src which isn't only wrong but plain stupid!
1230 - Troels Walsted Hansen fixed a problem with HTTP resume. Curl previously used
1231 a local variable badly, that could lead to crashes.
1235 Daniel (4 October 2000)
1236 - More docs written. The curl_easy_getinfo.3 man page is now pretty accurate,
1237 as is the -w section in curl.1. I added two options to enable the user to
1238 get information about the received headers' size and the size of the HTTP
1239 request. T. Bharath requested them.
1241 Daniel (3 October 2000)
1242 - Corrected a sever free() before use in the new add_buffer_send()! ;-)
1246 Daniel (3 October 2000)
1247 - Jason S. Priebe sent me patches that changed the way curl issues HTTP
1248 requests. The entire request is now issued in one single shot. It didn't do
1249 this previously, and it has turned out that since the common browsers do it
1250 this way, some sites have turned out to work with browsers but not with
1251 curl! Although this is not a client-side problem, we want to be able to
1252 fully emulate browsers, and thus we have now adjusted the networking layer
1253 to slightly more appear as a browser. I adjusted Jason's patch, the faults
1256 Daniel (2 October 2000)
1257 - Anyone who ever uploaded data with curl on a slow link has noticed that the
1258 progess meter is updated very infrequently. That is due to the large buffer
1259 size curl is using. It reads 50Kb and sends it, updates the progress meter
1260 and loops. 50Kb is very much on a slow link, although it is pretty neat to
1263 I've now made an adjustment that makes curl use a 2Kb buffer for uploads to
1264 start with. If curl's average upload speed is faster than buffer size bytes
1265 per second, curl will increase the used buffer size up to max 50Kb. It
1266 should make the progress meter work better.
1270 Daniel (29 September 2000)
1271 - Ripped out the -w stuff from the library and put in the curl tool. It gets
1272 all the relevant info from the library using the new curl_easy_getinfo()
1275 - brad at openbsd.org mailed me a patch that corrected my kerberos mistake and
1276 removed a compiler warning from hostip.c that OpenBSD people get.
1278 Daniel (28 September 2000)
1279 - Of course (I should probably get punished somehow) I didn't properly correct
1280 the #include lines for the base64 stuff in the kerberos sources in the just
1281 released 7.3 package. They still include the *_krb.h files! Now, the error
1282 is sooo very easy to spot and fix so I won't bother with a quick bug fix
1283 release. I'll post a patch whenever one is needed instead. It'll be
1284 available in the CVS in a few minutes anyway.
1288 Daniel (28 September 2000)
1289 - Removed the base64_krb.[ch] files. They've now replaced the former
1292 Daniel (26 September 2000)
1293 - Updated some docs.
1295 - I changed the OpenSSL fix to work with older versions as well. The posted
1296 patch was only working with 0.9.6 and no older ones.
1300 Daniel (25 September 2000)
1301 - Erdmut Pfeifer informed us that curl didn't build with OpenSSL 0.9.6 and
1302 showed us what needed to get patched in order to make it build properly
1305 - Dirk Kruschewski found a bug in the cookie parser. I made an alternative
1306 approach to the solution Dirk himself suggested. The bug made a cookie
1307 header that didn't end with a trailing semicolon to not get parsed.
1309 - I've marked -c and -t deprecated now. If you use any of them, curl will tell
1310 you to use "-C -" or "-T -" instead. I don't think occupying two letters for
1311 nearly identical functions is good use. Also, -T - kind of follows the curl
1312 tradition of using - for stdin where a file name is expected.
1314 Daniel (23 September 2000)
1315 - Martin Hedenfalk provided the patch that finally made the krb4 ftp upload
1318 Daniel (21 September 2000)
1319 - The kerberos code is not quite thread-safe yet. There are a few more globals
1320 that need to be take care of. Let's get the upload working first!
1322 Daniel (20 September 2000)
1323 - Richard Prescott solved another name lookup buffer size problem. I took this
1324 opportunity to rewrite the GetHost() function. With these large buffer
1325 sizes, I think keeping them as local arrays quickly turn ugly. I now use
1326 malloc() to get the buffer memory. Thanks to this, I now can realloc() to a
1327 large buffer in case of demand (errno == ERANGE) in case a solution like
1328 that would become necessary. I still want to avoid that kind of nastiness.
1330 - Tried to compile and run curl on Linux for alpha and FreeBSD for alpha. Went
1331 as smooth as it could.
1333 - Added a docs/examples directory with two tiny example sources that show how
1334 to use libcurl. I hope users will supply me with more useful examples
1337 - Applied a patch by Jörn Hartroth to no longer use the word 'inteface' in the
1338 config struct in the src/main.c file since certain compilers have that word
1339 "reservered". I figure that is some kind of C++ decease.
1341 - Updated the curl.1 man page with --interface and --krb4.
1343 - Modified the base64Encode() function to work like the kerberos one, so that
1344 I could remove the use of that. There is no need for *two* base64 encoding
1349 Daniel (19 September 2000)
1350 - The kerberos4-layer source code that is much "influenced" by the original
1351 krb4 source code, through yafc into curl, was using quite a lot of global
1352 variables. libcurl can't work properly with globals like that why I had to
1353 clean up almost every function in the new security.c to make them use
1354 connection specific variables instead of the globals. I just hope I didn't
1355 destroy anything now... :-) configure updated, version string now reflects
1356 krb4 built-in. It almost works now. Only uploads are still being naughty.
1360 Daniel (18 September 2000)
1361 - Martin Hedenfalk supplied a major patch that introduces krb4-ftp support to
1362 curl. Martin is the primary author of the ftp client named yafc and he did
1363 not hesitate to help us implement this when I asked him. Many and sincere
1364 thanks to a splendid effort. It didn't even take many hours!
1366 - Stephen Kick supplied a big patch that introduces the --interface flag to
1367 the curl tool and CURLOPT_INTERFACE for libcurl. It allows you to specify an
1368 outgoing interface to use for your request. This may not work on all
1369 platforms. This needs testing.
1371 - Richard Prescott noticed that curl on Tru64 unix could core dumped if the
1372 name didn't resolve properly. This was due to the GetHost() function not
1373 returning an error even though it failed on some platforms!
1375 Daniel (15 September 2000)
1376 - Updated all sorts of documents in regards to the new proxytunnel support.
1380 Daniel (15 September 2000)
1381 - Kai-Uwe Rommel pointed out a problem in the httpproxytunnel stuff for ftp.
1382 Adjusted it. Added better info message when setting up the tunnel and the
1383 pasv message when doing the second connect.
1387 Daniel (15 September 2000)
1388 - libcurl now allows "httpproxytunnel" to an arbitrary host and port name. The
1389 second connection on ftp needed that.
1391 - TheArtOfHTTPScripting was corrected all over. I both type and spell really
1394 Daniel (14 September 2000)
1395 - -p/--proxytunnel was added to 'curl'. It uses the new
1396 CURLOPT_HTTPPROXYTUNNEL libcurl option that allows "any" protocol to tunnel
1397 through the specified http proxy. At the moment, this should work with ftp.
1399 Daniel (13 September 2000)
1400 - Jochen Schaeuble found that file:// didn't work as expected. Corrected this
1401 and mailed the patch to the mailing list.
1403 Daniel (7 September 2000)
1404 - I changed the #define T() in curl.h since it turned out it wasn't really
1405 a good symbol to use (when you compiled PHP with curl as a module, that
1406 define collided with some IMAP define or something). This was posted to the
1409 - I added extern "C" stuff in two header files to better allow libcurl usage
1410 in C++ sorces. Discussions on the libcurl list with Danny Horswell lead to
1415 Daniel (31 August 2000)
1416 - Albert Chin-A-Young fixed the configure script *again* and now it seems to
1417 detect Linux name resolving properly! (heard that before?)
1419 - Troels Walsted Hansen pointed out that downloading a file containing the
1420 letter '+' from an ftp server didn't work. It did work from HTTP though and
1421 the reason was my lame URL decoder.
1423 - I happened to notice that -I didn't at all work on ftp anymore. I corrected
1428 Daniel (30 August 2000)
1429 - Understanding AIX is a hard task. I believe I'll never figure out why they
1430 solve things so differently from the other unixes. Now, I'm left with the
1431 AIX 4.3 run-time warnings about duplicate symbols that according to this
1432 article (http://www.geocrawler.com/archives/3/405/1999/9/0/2593428/) is a
1433 libtool flaw. I tried the mentioned patch, although that stops the linking
1436 So, if I select to ignore the ld warnings there are compiler warnings that
1437 fill the screen pretty bad when curl compiles. It turns out that if I want
1438 to '#include <arpa/inet.h>', I can get tid of the warnings by include the
1439 following three include files before that one:
1441 #include <net/if_dl.h>
1442 #include <sys/mbuf.h>
1443 #include <netinet/if_ether.h>
1445 Now, is it really sane to add those include files before arpa/inet.h in all
1446 the source files that include it?
1448 Thanks to Albert Chin-A-Young at thewrittenword.com who gave me the AIX
1449 login to try everything on.
1451 Daniel (24 August 2000)
1452 - Jan Schmidt supplied us a new VC6 makefile for Windows as the previous one
1453 was not up to date but lacked several object files.
1455 - More work on the naming.
1457 - Albert Chin-A-Young provided a configure-check for large file support, as
1458 some systems seem to need that for them to work. Had to change the position
1459 for the config.h include file in every .c file in the libcurl dir...
1461 - As suggested on the mailing list (by Troy Engel), I did use a --data-binary
1462 option instead of the messy way I've left described below. It seems to
1463 work. The libcurl fix remained the same as yesterday.
1465 Daniel (23 August 2000)
1466 - Back on the -d stripping newlines thing. The 'plain post' thing was added
1467 when I had no thought of that one could actually post binary data with
1468 it. Now, I have to add this functionality in a graceful manner and I think
1469 I've managed to come up with a way: '-d @file;binary' will thus post the
1470 file binary, exactly as its contents are. It is implemented with a new
1471 *setopt() option (CURLOPT_POSTFIELDSIZE) to set the postfield size, since
1472 libcurl can't strlen() the data in these cases.
1474 - Albert Chin-A-Young made some very serious efforts and all the name
1475 resolving problems seem to have been sorted out now on all the platforms
1476 that previously showed them. I'll make another release now anyday because of
1479 - The FAQ was much enhanced when it comes to the licensing issues thanks to
1482 Daniel (21 August 2000)
1483 - Rick Welykochy pointed out a problem when you use -d to post and you want to
1484 keep the newlines, as curl strips them off as a bonus before posting...
1485 This needs to be addressed.
1489 Daniel (21 August 2000)
1490 - Got more people involved in the gethostbyname_r() mess. Caolan McNamara sent
1491 me configure-code that turned out to be very similar to my existing tests
1492 which only make me more sure I'm on the right path. I changed the order of
1493 the tests slightly, as it seems that some compilers don't yell error if a
1494 function is used with too many parameters. Thus, the first tested function
1495 will seem ok... Let's hope more compilers think of too-few parameters as bad
1496 manners, as we're now trying the functions in that order; fewer first. I
1497 should also add that Lars Hecking mailed me and volunteered to run tests on
1498 a few odd systems. Coalan is keeping his work over at
1499 http://www.csn.ul.ie/~caolan/publink/gethostbyname_r/. Might be handy in the
1502 Daniel (18 August 2000)
1503 - I noticed I hadn't increased the name lookup buffer in lib/ftp.c. I don't
1504 think this is the reason for the continued trouble though.
1506 Daniel (17 August 2000)
1507 - Fred Noz corrected my stupid mistakes in the gethostbyname_r() fluff. It
1508 should affect some AIX, Digital Unix and HPUX 10 systems.
1510 Daniel (15 August 2000)
1511 - Mathieu Legare compiled and build 7.1 without errors on both AIX 4.2 as well
1512 as AIX 4.3. Now why did problems occur before?
1514 - Fred Noz reported a -w/--write-out bug that caused it to malfunction when
1515 used combined with multiple URL retrievales. All but the first display got
1518 Daniel (11 August 2000)
1519 - Jason Priebe and an anonymous friend found some host names the Linux version
1520 of curl could not resolve. It turned out the buffer used to retrieve that
1521 information was too small. Fixed. One could argue about the usefulness of
1522 not having the slightest trace of a man page for gethostbyname_r() on my
1523 Linux Redhat installation...
1525 Daniel (10 August 2000)
1526 - Balaji S Rao was first in line to note the missing possibility to replace
1527 the Content-Type: and Content-Length: headers when doing -d posts. I added
1528 the possibility just now. It seems some people wants to do standard posts
1529 using custom Content-Types.
1531 Daniel (8 August 2000)
1532 - Mike Dowell correctly discovered that curl did not approve of URLs with no
1533 user name but password. As in 'http://:foo@haxx.se'. I corrected this.
1537 Daniel (7 August 2000)
1538 - My AIX 4 fix does not work. I need help from a AIX 4 hacker.
1540 - I added my new document in the docs directory. It is aimed to become a sort
1541 of tutorial on how to do HTTP scripting with curl.
1543 Daniel (4 August 2000)
1544 - Working with Rich Gray on compiling curl for lots of different platforms.
1545 My fix for AIX 3.2 was not good enough and was slightly changed, I had to
1546 move an include file before another, as is now described in the source.
1548 AIX 4.2 (4.X?) has different gethostbyname_r() and gethostbyaddr_r()
1549 functions that the configure script didn't check for and thus the compile
1550 broke with an error. I have now changed the gethostbyname_r() check in the
1551 configure file to support all three versions of both these functions. My
1552 implementation that uses the AIX-style is though not yet verified and I may
1553 get problems to fix it if it turns out to bug since I don't have access to
1554 any system using that.
1556 For problems like that, I made the configure script allow --disable-thread
1557 to completely switch off the check for threadsafe versions of a few
1558 functions and thus go with the "good old versions" that tend to work
1559 although will break thread-safeness for libcurl. Most people won't use
1560 libcurl for other things than curl though, and curl doesn't need a
1563 - Working on my big tutorial about HTTP scripting with curl.
1565 Daniel (1 August 2000)
1566 - Rich Gray spotted a problem in src/setup.h caused by a #define strequal()
1567 that was just a left-over from passed times. The strequal() is now a true
1568 function supplied by libcurl for a portable case insensitive string
1569 comparison. I added the prototypes in include/curl.h and removed the
1570 now obsolete #define.
1572 - Igor Khristophorov made a fix to allow resumed download from Sun's
1573 JavaWebServer/1.1.1. It seems that their server sends bad Content-Range
1576 - The makefiles forced a static library build, which is bad since we now use
1577 libtool and thus have excellent shared library support! Albert Chin-A-Young
1582 Daniel (1 August 2000)
1583 - Albert Chin-A-Young pointed out that 'make install' did not properly create
1584 the header include directory, why it failed to install the header files as
1585 it should. Automake isn't really equipped to deal with subdirectories
1586 without Makefiles in any nice way. I had to run ahead and add Makefiles in
1587 both include and include/curl before I managed to create a top-level
1588 makefile that succeeds in install everything properly!
1590 - Ok, no more "features" added now. Let's just verify that there's no major
1593 Daniel (31 July 2000)
1594 - Both Jeff Schasny and Ketil Froyn asked me how to tell curl not to send one
1595 of those internally generated headers. They didn't settle with the blank
1596 ones you could tell curl to use. I rewrote the header-replace stuff a
1597 little. Now, if you replace an internal header with your own and that new
1598 one is a blank header you will only remove the internal one and not get any
1599 blank. I couldn't figure out any case when you want that blank header.
1601 Daniel (29 July 2000)
1602 - It struck me that the lib used localtime() which is not thread-safe, so now
1603 I use localtime_r() in the systems that has it.
1605 - I went through this entire document and removed all email addresses and left
1606 names only. I've really made an effort to always note who brought be bug
1607 reports or fixes, but more and more people ask me to remove the email
1608 addresses since they become victims for spams this way. Gordon Beaton got me
1611 Daniel (27 July 2000)
1612 - Jörn Hartroth found out that when you specified a HTTP proxy in an
1613 environment variable and used -L, curl failed in the second fetch. I
1614 corrected this problem and posted a patch to the list. No need for an extra
1615 beta release just for this.
1619 Daniel (27 July 2000)
1620 - So, libtool replaced two of my files with symbolic links and I forgot to add
1621 the two new libtool files to the release archive (and they were added as
1622 symlinks as well!) This of course lead to that the configure script failed
1627 Daniel (25 July 2000)
1628 - Kristian Köhntopp <kris at koehntopp.de> brought a fix that makes libcurl
1629 libtoolified, just as we've wanted for a while now. He also made the
1630 recently added man pages get installed properly on 'make install' and some
1631 other nice cleanups.
1633 - In a discussion with Eetu Ojanen it struck me that if we use curl to get a
1634 page using a password, and that page then sends a Location: to another
1635 server that curl follows, curl will send the user name and password to that
1638 Now, I'll never be able to make curl do Location: following all that perfect
1639 and you're all sooner or later required to write a script to do several
1640 fetches when you're doing advanced stuff, but now I've modified curl to at
1641 least *only* send the user name and password to the original server. Which
1642 means that if get a page from server A with a password, that forwards curl
1643 to server B, curl won't use the password there. If server B then forwards
1644 curl back to server A again, the password will be used again.
1646 This is not a perfect implementation, as in a browser case it would only use
1647 the password if the left-prefix of the first path is the same. I just think
1648 that this fix prevents a somewhat lurky "security hole".
1650 As a side-note in this subject: HTTP passwords are sent in cleartext and
1651 will never be considered to be safe or secure. Use HTTPS for that.
1653 - As discussed on the mailing list, I converted the FTP response reading
1654 function into using select() which then allows timeouts (even under win32!)
1655 if the command-reply session gets too slow or dies completely. I made a
1656 default timeout on 3600 seconds unless anything else is specified, since I
1657 don't think anyone wants to wait more than that for a single character to
1660 - Torsten Foertsch <torsten.foertsch at gmx.net> brought a set of fixes for
1661 the rfc1867 form posts. He introduced 'name=<file' which brings a means to
1662 suuply very large text chunks read from the given file name. It differs from
1663 'name=@file' in the way that this latter thing is marked in the uploaded
1664 contents as a file upload, while the first is just text (as in a input or
1665 textarea field). Torsten also corrected a bug that would happen if you used
1666 %s or similar in a -F file name.
1668 - As discovered by Nico Baggus <Nico.Baggus at mail.ing.nl>, when transferring
1669 files to/from FTP using type ASCII curl should not expect the transfer to be
1670 the exact size reported by the server as the file size. Since ASCII may very
1671 well mean that the content is translated while transfered, the final size
1672 may very well differ. Therefor, curl now ignores the file size when doing
1673 ASCII transfers in FTP.
1675 Daniel (24 July 2000)
1676 - Added CURLOPT_PROXYPORT to the curl_easy_setopt() call to allow the proxy
1677 port number to be set separately from the proxy host name.
1679 - Andrew <andrew at ugh.net.au> pointed out a netrc manual bug.
1681 - The FTP transfer code now accepts a 250-code as well as the previously
1682 accepted 226, after a successful file transfer. Mohan <mnair at
1683 evergreen-funds.com> pointed this out.
1685 - The check for *both* nsl and socket was never added in the v7 configure.in
1686 when I moved the main branch. I re-added that check to configure.in. This was
1687 discovered by Rich Gray.
1689 - Howard, Blaise <Blaise.Howard at factiva.com> pointed out a missing free() in
1690 curl_disconnect() which of course meant libcurl ate memory.
1692 - Brian E. Gallew noted that the HTTP 'Host:' header curl sent did not
1693 properly include the port number if non-default ports were used. This should
1694 now have been fixed.
1696 - HTTP connect errors now return errors earlier. This was most notably causing
1697 problems when the HTTPS certificate had problems and later caused a crash.
1698 Many thanks to Gregory Nicholls <gnicholls at level8.com> for discovering
1699 and suggesting a fix...
1701 Daniel (21 June 2000)
1702 - After a "bug report" I received where the user was using both -F and -I in a
1703 HTTP request (it severly confused the library I should add), I added some
1704 checks to src/main.c that prevents setting more than one HTTP request
1705 command, no matter what the user wants! ;-)
1709 Daniel (20 June 2000)
1710 - I did a major replace in many files to use the new curl domain haxx.se
1711 instead of the previous one.
1713 - As Eetu Ojanen suggested, I finally took the step and now libcurl no longer
1714 makes a POST after it has followed a location. When the initial POST has
1715 been done, it'll turned into a GET for the further requests. This is only
1716 interesting when using -L/--location *and* doing a POST at the same time.
1718 While messing with this, I added another weird feature I call 'auto
1719 referer'. If you append ';auto' to the right of a given referer string (or
1720 only use that string as referer), libcurl will automatically set the
1721 previoud URL as refered when it follows a Location: and gets a succeeding
1724 - My hero Rich Gray found the very obscure FTP bug that happened to him only
1725 when passing through a particular firewall and using the PORT command. It
1726 turned out that PORT was the only command in the lib/ftp.c source that
1727 didn't send a proper \r\n sequence but instead used the faulty \n which as
1728 it seemed is supported by most major ftp servers... :-O
1732 Daniel (16 June 2000)
1733 - I had avoided this long enough now, so I moved the alternative progress bar
1734 stuff from the lib and added it to the client code. This is now using the
1735 recently added progress callback and it seems to work pretty much like
1736 before. Since it is only one progress bar and you and download and upload at
1737 the same time, this bar shows the combined progress of both directions. This
1738 code was just ported from the old place to this, Lars is still our saviour!
1739 ;-) This also made the documentation more accurate since I never removed
1740 this function from any docs! Although I now removed the CURLOPT_PROGRESSMODE
1741 from the library since the lib has only one internal progress meter and it
1742 will never get another. It is although likely that the internal one also
1743 will be moved to the client code in the future (when I have other means of
1744 getting the writeout data and move that too to the client).
1746 - I took the opportunity to verify that standard progress meter works and I
1747 found out it didn't get inited properly. Grrr. I corrected that as well.
1749 Daniel (15 June 2000)
1750 - I thought I'd better verify that the -F option still works in v7 and of
1751 course it didn't... :-/ Anyway, I had the problems I could discover
1752 corrected. About one month of beta testing and not a single person has used
1753 this feature with v7?
1755 - Björn correctly pointed out that the --progress-bar still doesn't work in
1758 Daniel (14 June 2000)
1759 - Tim Tassonis discovered that curl 7 didn't handle normal http POST as it
1760 should. I corrected this.
1764 Daniel (14 June 2000)
1765 - Björn Stenberg pointed out several problems (related to win32 compiling):
1766 lib/strequal.c had a bad #ifdef for one of the string comparisons (win32)
1767 src/main.c had several minor problems
1768 lib/makefile.m32 had getpass.[co] twice
1769 src/config-win32.h lacked the HAVE_FCNTL_H define
1770 both config-win32.h files now only set the HAVE_UNISTD_H define if the
1771 define MINGW32 is set, and I modified src/makefile.m32 and lib/makefile.m32
1776 Daniel (14 June 2000)
1777 - Applied Luong Dinh Dung's comments about a few win32 compile problems.
1779 - Applied Björn Stenberg's suggested fix that turns the win32 stdout to
1780 binary. It won't do it if the -B / --use-ascii option is used. That option
1781 is now an extended version of the previous -B /--ftp--ascii. The flag was
1782 already in use be the ldap as well so the new name fits pretty good. The
1783 libcyrl CURLOPT_TRANSFERTEXT was also introduced as an alias to the now
1784 obsolete CURLOPT_FTPASCII. Can't verify this fix myself as I have no win32
1787 Daniel (13 June 2000)
1788 - Luong Dinh Dung <dung at sch.bme.hu> found a problem in curl_easy_cleanup()
1789 since it free()ed the main curl struct *twice*. This is now corrected.
1791 Daniel (9 June 2000)
1792 - Updated the RESOURCES file, added a README.win32 file.
1794 Daniel (8 June 2000)
1795 - So I finally added the progress callback to the *setopt() options and it
1796 should work now. I don't have the energy to write any test program for it
1798 - Made the callback function typedefs public in curl/curl.h for comfort. Just
1799 in case anyone wanna fiddle with such pointers.
1800 - Updated the curl_easy_setopt() man page accordingly.
1804 Daniel (2 June 2000)
1805 - I noticed that when doing Location: following, we lost custom headers in all
1806 but the first request.
1807 - Removed the 'HttpPost' struct and moved the header stuff to the more generic
1809 - Added some better slist-cleanups in src/main.c
1813 Daniel (31 May 2000)
1814 - So I discovered that I released the 7.0.2beta without it being able to
1815 compile under Linux. gethostbyname_r() and gethostbyaddr_r() turned out to
1816 feature a different amount of arguments on different systems so I had to add
1817 a configure check for this and adjust the code slightly.
1821 Daniel (29 May 2000)
1822 - Corrected the bits.* assignments when using CURLOPT options that only
1823 toggles one of those bits.
1825 - Applied the huge patches from David LeBlanc <dleblanc at qnx.com> that add
1826 usage of the gethostbyname_r() and similar functions in case they're around,
1827 since that make libcurl much better threadsafe in many systems (such as
1828 solaris). I added the checks for these functions to the configure script.
1830 I can't explain why, but the inet_ntoa_r() function did not appear in my
1831 Solaris include files, I had to add my own include file for this for now.
1833 Daniel (22 May 2000)
1834 - Jörn Hartroth brought me fixes to make the win32 version compile properly as
1835 well as a rename of the 'interface' field in the urldata struct, as it seems
1836 to be reserved in some gcc versions!
1838 - Rich Gray struck back with yet some portability reports. Data General DG/UX
1839 needed a little fix in lib/ldap.c since it doesn't have RTLD_GLOBAL defined.
1840 More fixes are expected as a result of Richies very helpful work.
1844 Daniel (21 May 2000)
1845 - Updated lots of #defines, enums and variable type names in the library. No
1846 more weird URG or URLTAG prefixes. All types and names should be curl-
1847 prefixed to avoid name space clashes. The FLAGS-parameter to the former
1848 curl_urlget() has been converted into a bunch of flags to use in separate
1849 setopt calls. I'm still focusing on the easy-interface, as the curl tool is
1852 - Bjorn Reese has provided me with an asynchronous name resolver that I plan
1853 to use in upcoming versions of curl to be able to gracefully timeout name
1858 Daniel (18 May 2000)
1859 - Introduced LIBCURL_VERSION_NUM to the curl.h include file to better allow
1860 source codes to be dependent on the lib version. This define is now set to
1861 a dexadecimal number, with 8 bits each for major number, minor number and
1862 patch number. In other words, version 1.2.3 would make it 0x010203. It also
1863 makes a larger number a newer version.
1865 Daniel (17 May 2000)
1866 - Martin Kammerhofer correctly pointed out several flaws in the FTP range
1867 option. I corrected them.
1868 - Removed the win32 winsock init crap from the lib to the src/main.c file
1869 in the application instead. They can't be in the lib, especially not for
1870 multithreaded purposes.
1872 Daniel (16 May 2000)
1873 - Rewrote the src/main.c source to use the new easy-interface to libcurl 7.
1874 There is still more work to do, but the first step is now taken.
1875 <curl/easy.h> is the include file to use.
1877 Daniel (14 May 2000)
1878 - FTP URLs are now treated slightly different, more according to RFC 1738.
1879 - FTP sessions are now performed differently, with CWD commands to change
1880 directory instead of RETR/STOR/LIST with the full path. Discussions with
1881 Rich Gray made me notice these problems.
1882 - Janne Johansson discovered and corrected a buffer overflow in the
1884 - I had to add a lib/strequal.c file for doing case insensitive string
1885 compares on all platforms.
1887 Daniel (8 May 2000):
1888 - Been working lots on the new lib.
1889 - Together with Rich Gray, I've tried to adjust the configure script to work
1890 better on the NCR MP-RAS Unix.
1892 Daniel (2 May 2000):
1893 - Albert Chin-A-Young pointed out that I had a few too many instructions in
1894 configure.in that didn't do any good.
1896 Daniel (24 April 2000):
1897 - Added a new paragraph to the FAQ about what to do when configure can't
1898 find OpenSSL even though it is installed. Supplied by Bob Allison
1900 Daniel (12 April 2000):
1901 - Started messing around big-time to convert the old library interface to a
1904 Daniel (8 April 2000):
1905 - Made the progress bar look better for file sizes between 9999 kilobytes
1906 and 100 megabytes. They're now displayed XX.XM.
1907 - I also noticed that ftp fetches through HTTP proxies didn't add the user
1908 agent string. It does now.
1909 - Habibie <habibie at MailandNews.com> supplied a pretty good way to build RPMs
1910 on a Linux machine. It still a) requires me to be root to do it, b) leaves
1911 the rpm packages laying at some odd place on my disk c) doesn't work to
1912 build the ssl version of curl since I didn't install openssl from an rpm
1913 package so now the rpm crap thinks I don't have openssl and refuses to build
1914 a package that depends on ssl... Did I mention I don't get along with RPM?
1915 - Once again I received a bug report about autoconf not setting -L prior to -l
1916 on the command line when checking for libs. In this case it made the native
1917 cc compiler on Solaris 7 to fail the OpenSSL check. This has previously been
1918 reported to cause problems on HP-UX and is a known flaw in autoconf 2.13. It
1919 is a pity there's no newer release around...
1921 Daniel (4 April 2000):
1922 - Marco G. Salvagno supplied me with two fixes that
1923 appearantly makes the OS/2 port work better with multiple URLs.
1925 Daniel (2 April 2000):
1926 - Another Location: fix. This time, when curl connected to a port and then
1927 followed a location with an absolute URL to another port, it misbehaved.
1929 Daniel (27 March 2000):
1930 - H. Daphne Luong pointed out that curl was wrongly
1931 messing up the proxy string when fetching a document through a http proxy,
1932 which screwed up multiple fetches such as in location: followings.
1934 Daniel (23 March 2000):
1935 - Marco G. Salvagno corrected my badly applied patch he
1936 actually already told me about!
1938 - H. Daphne Luong brought me a fix that now makes curl
1939 ignore select() errors in the download if errno is EINTR, which turns out to
1940 happen every now and then when using libcurl multi-threaded...
1942 Daniel (22 March 2000):
1943 - Wham Bang supplied a couple of win32 fixes. HAVE_UNAME
1944 was accidentally #defined in config-win32.h, which it shouldn't have been.
1945 The HAVE_UNISTD_H is not defined when compiling with the Makefile.vc6
1946 makefile for MS VC++.
1948 Daniel (21 March 2000):
1949 - I removed the AC_PROG_INSTALL macro from configure.in, since it appears that
1950 one of the AM_* macros searches for a BSD compatible install already. Janne
1951 Johansson made me aware of this.
1955 Daniel (21 March 2000):
1956 - Paul Harrington quickly pointed out to me that 6.5.1
1957 crashes hard. I upload 6.5.2 now as quickly as possible! The problem was
1958 the -D adjustments in src/main.c.
1962 Daniel (20 March 2000):
1963 - An anonymous post on sourceforge correctly pointed out a possible buffer
1964 overflow in the curl_unescape() function for URL conversions. The main
1965 problem with this bug is that the ftp download uses that function and this
1966 single- byte overflow could lead to very odd bugs (as one reported by Janne
1969 Daniel (19 March 2000):
1970 - Marco G. Salvagno supplied me with a series of patches
1971 that now allows curl to get compiled on OS/2. It even includes a section in
1972 the INSTALL file. Very nice job!
1974 Daniel (17 March 2000):
1975 - Wham Bang supplied a patch for the lib/Makefile.vc6
1976 file. We still need some fixes for the config-win32.h since it appears that
1977 VC++ and mingw32 have different opinions about (at least) unistd.h's
1980 Daniel (15 March 2000):
1981 - I modified the -D/--dump-header workings so that it doesn't write anything
1982 to the file until it needs to. This way, you can actually use -b and -D
1983 on the same file if you want repeated invokes to store and read the cookies
1984 in that one single file.
1986 - Poked around in lots of texts. Added the BUGS file for bug reporting stuff.
1987 Added the classic HTTP POST question to the FAQ, removed some #ifdef WIN32
1988 stuff from the sources (they're covered by the config-win32.h now).
1990 - Pascal Gaudette fixed a missing ldap.c problem in the
1991 Makefile.vc6 file. He also addressed a problem in src/config-win32.h.
1993 Daniel (14 March 2000):
1994 - Paul Harrington pointed out that the 'http_code' variable in the -w output
1995 was never written. I fixed it now.
1997 - Janne Johansson reported the complaints that OpenBSD does
1998 when getdate.c #includes malloc.h. It claims stdlib.h should be included
1999 instead. I added #ifdef HAVE_MALLOC_H code in getdate.y and two checks in
2000 the configure.in for malloc.h and stdlib.h.
2004 Daniel (13 March 2000):
2005 - <curl at spam.wolvesbane.net> pointed out that the way curl sent cookies in a
2006 single line wasn't enjoyed by IIS4.0 servers. In my view, that is not what
2007 the standards say, but I added a white space between the name/value pairs to
2008 perhaps make them work better.
2010 - Added the perl check back in the configure.in again since the mkhelp.pl
2013 - Made some beautifications in the curl man page.
2015 Daniel (3 March 2000):
2016 - Jörn helped me update the config-win32.h files with HAVE_SETVBUF and
2019 Daniel (3 March 2000):
2020 - Uploaded the 6.5pre2 package.
2022 Daniel (2 March 2000):
2023 - Removed the perl-programs from the distribution, they never made many people
2024 happy and I'll still keep them available on the web.
2026 - Added the -w and -N stuff to the man page. Documented the new progress meter
2027 display in README.curl.
2029 - Jörn Hartroth, Chris <cbayliss at csc.come> and Ulf
2030 Möller from the openssl development team helped bringing me the details for
2031 fixing an OpenSSL usage flaw. It became apparent when they released openssl
2032 0.9.5 since that barfed on curl's bad behavior (not seeding a random number
2035 - Yet another option: -N/--no-buffer disables buffering in the output stream.
2036 Probably most useful for very slow transfers when you really want to get
2037 every byte curl receives within some preferred time. Andrew <tmr at gci.net>
2040 - Damien Adant mailed me his fixes for making curl compile on Ultrix.
2042 Daniel (24 February 2000):
2043 - Applied Jörn Hartroth's fixes for config-win32.h and lib/Makefile.w32.
2045 I should also make a note here, if nothing else to myself, that when using
2046 the %-syntax for variables in DOS command prompts, you must use two %-
2047 letters for each one since that is an escape letter there! Maybe I should
2048 use another letter instead!
2050 - Added more variables to -w:
2058 - Made -w@filename read the syntax from a file and -w@- reads the syntax from
2059 stdin in the good old "standard" curl way.
2061 Daniel (22 February 2000):
2062 - Released a 6.5pre1 version to get some test and user feedback.
2064 Daniel (21 February 2000):
2066 - I added the -w/--write-out flag and some variables to go with it. -w is a
2067 single string, whatever you enter there will be written out when curl has
2068 completed a successful request. There are some variable substitutions and
2069 they are specified as '%{variable}' (without the quotes). Variables that
2070 exist as of this moment are:
2072 total_time - total transfer time in seconds (with 2 decimals)
2073 size_download - total downloaded amount of bytes
2074 size_upload - total uploaded amount of bytes
2075 speed_download - the average speed of the entire download
2076 speed_upload - the average speed of the entire upload
2078 I will of course add more variables, but I need input on these and others.
2080 - It struck me that the -# progress bar will be hard to just apply on the new
2081 progress bar concept. I need some feedback on this before that'll get re-
2084 Daniel (16 February 2000):
2085 - Jörn Hartroth brought me some fixes for the progress meter and I continued
2086 working on it. It seems to work for http download, http post, ftp download
2087 and ftp upload. It should be a pretty good test it works generally good.
2089 - Still need to add the -# progress bar into the new style progress interface.
2091 - Gonna have a go at my new output option parameter next.
2093 Daniel (15 February 2000):
2094 - The progress meter stuff is slowly taking place. There's more left before it
2095 is working ok and everything is tested, but we're reaching there. Slowly!
2097 Daniel (11 February 2000):
2098 - Paul Marquis fixed the config file parsing of curl to
2099 deal with any-length lines, removing the previous limit of 4K.
2101 - Eetu Ojanen's suggestion of supporting the @-style for -b
2102 is implemented. Now -b@<filename> works as well as the old style. -b@- also
2103 similarly reads the cookies from stdin.
2105 - Reminder: -D should not write to the file until it needs to, in the same way
2106 -o does. That would enable curl to use -b and -D on the same file...
2108 - Ellis Pritchard made getdate.y work for MacOS X.
2110 - Paul Harrington helped me out finding the crash in the
2111 cookie parser. He also pointed out curl's habit of sending empty cookies to
2114 Daniel (8 February 2000):
2115 - Ron Zapp corrected a problem in src/urlglob.c that
2116 prevented curl from getting compiled on sunos 4. The problem had to do
2117 with the difference in sprintf() return code types.
2119 - Transfer() should now be able to download and upload simultaneously. Let's
2120 do some progress meter fixes later this week.
2122 Daniel (31 January 2000):
2123 - Paul Harrington found another core dump in the cookie
2124 parser. Curl doesn't properly recognize the 'version' keyword and I think
2125 that is what caused this. I need to refresh some specs on cookies and see
2126 what else curl lacks to improve this a bit more once and for all.
2128 RFC 2109 clearly specifies how cookies should be dealt with when they are
2129 compliant with that spec. I don't think many servers are though...
2131 - Mark W. Eichin found that while curl is uploading a form
2132 to a web site, it doesn't read incoming data why it'll hang after a while
2133 since the socket "pipe" becomes full.
2135 It took me two hours to rewrite Download() and Upload() into the new
2136 single function Transfer(). It even seems to work! More testing is required
2137 of course... I should get the header-sending together in a kind of queue
2138 and let them get "uploaded" in Transfer() as well.
2140 - Zhibiao Wu pointed out a curl bug in the location: area,
2141 although I did not get a reproducible way to do this why I have to wait
2142 with fixing anything.
2144 - Bob Schader suggested I should implement resume
2145 support for the HTTP PUT operation, and as I think it is a valid suggestion
2148 Daniel (25 January 2000):
2149 - M Travis Obenhaus pointed out a manual mixup with -y and -Y that was
2152 - Jens Schleusener pointed out a problem to compile
2153 curl on AIX 4.1.4 and gave me a solution. This problem was already fixed
2154 by Jörn's recent #include modifications!
2156 Daniel (19 January 2000):
2157 - Oskar Liljeblad pointed out and corrected a problem
2158 in the Location: following system that made curl following a location: to a
2159 different protocol to fail.
2161 At January 31st I re-considered this fix and the surrounding source code. I
2162 could not really see that the patch did any difference, why I removed it
2163 again for further research and debugging. (It disabled location: following
2164 on server not running on default ports.)
2166 - Jörn Hartroth brought a fix that once again
2167 made it possible to select progress bar.
2169 - Jörn also fixed a few include problems.
2173 Daniel (17 January 2000):
2174 - Based on suggestions from Björn Stenberg, I made the
2175 progress deal better with larger files and added a "Time" field which shows
2176 the time spent on the download so far.
2177 - I'm now using the CVS repository on sourceforge.net, which also allows web
2178 browsing. See http://curl.haxx.nu.
2180 Daniel (10 January 2000):
2181 - Renumbered some enums in curl/curl.h since tag number 35 was used twice!
2182 - Added "postquote" support to the ftp section that enables post-ftp-transfer
2184 - Now made the -Q/--quote parameter recognize '-' as a prefix, which means
2185 that command will be issued AFTER a successful ftp transfer. This can of
2186 course be used to delete or rename a file after it has been uploaded or
2187 downloaded. Use your imagination! ;-)
2188 - Since I do the main development on solaris 2.6 now, I had to download and
2189 install GNU groff to generate the hugehelp.c file. The solaris nroff cores
2190 on the man page! So, in order to make the solaris configure script find a
2191 better result I made gnroff get checked prior to the regular nroff.
2192 - Added all the curl exit codes to the man page.
2193 - Jim Gallagher properly tracked down a bug in autoconf
2194 2.13. The AC_CHECK_LIB() macro wrongfully uses the -l flag before the -L
2195 flag to 'ld' which causes the HP-UX 10.20 flavour to fail on all libchecks
2196 and therefore you can't make the configure script find the openssl libs!
