12 - All callback functions now take 'void *' instead of 'FILE *'. This is made
13 this way to make it more obvious to people that anything can be passed to
14 them (by using the apropriate option). After discussions with Sterling
18 - Cris Bailiff fixed a chunked transfer encoding problem with persistent
19 connection that made libcurl fail if the persistent connection used mixed
20 chunked and non-chunked transfers.
22 - Cris Bailiff fixed a bad treatment of 304-replies, as they would not be
23 treated as content-length 0 replies but would cause a "hang" until the
24 server timed-out and closed the connection.
26 - Brad Burdick found a minor problem in the docs/examples/Makefile.am
28 Daniel (27 April 2001)
29 - Updated the INTERALS document again. It was lagging a bit. I think I made it
30 more easy to follow now as well.
32 - Brad Burdick found a problem with persistent connections when curl received
33 a "Content-Length: 0" header.
35 - Giuseppe D'Ambrosio was first out to report that TELNET doesn't work in curl
36 compiled/built on win32. It seems to work for unixes though!
38 - Dave Hamilton reported weird problems with CURL/PHP that I really can't
39 explain at the moment. I'm hoping on some help from the PHP crew.
41 Daniel (26 April 2001)
42 - I rewrote the FTP command response function. I had to do it to make ftps
43 work, as the OpenSSL read()-function didn't work the same way the normal
44 unix read() does, but it was also a huge performance boost. Previously the
45 function read one byte at a time, now it reads very large chunks, and it
46 makes a notable speed difference.
48 Daniel (25 April 2001)
49 - Connection re-use when not using a proxy didn't work properly for
50 non-default port numbers.
52 Daniel (24 April 2001)
53 - I've noticed that FTPS doesn't work. We attempt to use ssl even for the
54 data transfer, which causes the transfer to 'hang'... We need to fix this.
56 - Improved the test suite to use 'stunnel' to do HTTPS and FTPS testing on
57 the alredy written perl servers easily.
59 Daniel (23 April 2001)
60 - The OpenSSL version string recently modified didn't zero terminate one
61 of the generated strings properly, which could lead to a crash or simply
62 weird version string output!
66 Daniel (22 April 2001)
67 - Rosimildo da Silva updated the Makefiles for Borland/Windows.
69 - Eric Rautman pointed out a problem with persistent connections that would
70 lead to broken Host: headers in the second HTTP request.
72 Daniel (20 April 2001)
73 - Added man pages for the curl_strequal() and curl_mprintf() families. Wrote
74 a 'libcurl overview' man page.
76 - Spell-fixed some documents.
78 - S. Moonesamy corrected mistakes in the man page.
80 - Cris Bailiff fixed the curl_slists options in the perl interface, present
81 separately in the Curl::easy 1.1.4 package.
83 Daniel (19 April 2001)
84 - Linus Nielsen Feltzing removed the decimals from the size variables in the
85 --write-out output. We hardly ever get fraction of bytes! :-)
89 Daniel (19 April 2001)
91 - Albert Chin provided a configure patch for the AC_SYS_LARGEFILE macro.
93 Daniel (18 April 2001)
94 - Input from Michael Mealling made me add --feature to curl-config. It
95 displays a list of features that have been built-in in the current
96 libcurl. The currently available features that can be listed are: SSL, KRB4
99 - I committed Cris and Georg's perl interface work. They've got callbacks
100 working and options that receives those slist pointers.
102 - Puneet Pawaia detected a problem with resumed downloads that use persistent
103 connections and I made a rather large writeup to correct this. It is
104 important that all session-data is stored in the connectdata struct and not
105 in the main struct as this previously did.
107 Daniel (17 April 2001)
108 - Frederic Lepied fixed a ftp resumed download problem and introduced a new
109 error code that lets applications be able to detect when a resumed download
110 actually didn't download anything since the whole file is already present.
111 Should this return OK instead?
113 - I added 'curl-config.in' to the root dir and configure script. Now, a
114 curl-config script is made when curl is built. The script can be used to
115 figure out compile time options used when libcurl was built, which in turn
116 should be options YOU should use to build applications that use libcurl.
118 This *-config style is not a new idea, but something that has been used
119 successfully in other (library based) projects.
121 - Phil Karn pointed out that libcurl wrongly did not always use GMT time zone
122 for the If-Modified-Since style headers.
124 - Georg Schwarz pointed out an extra needed #include file needed in src/main.c
125 for curl to build on Ultrix.
127 Daniel (11 April 2001)
128 - Cris Bailiff pointed out two problems that I corrected. First, libcurl's use
129 of the environment variable HTTP_PROXY in uppercase may become a security
130 hazard when people use libcurl in a server/cgi situation where the server
131 sets the HTTP_*-variables according to incoming headers in the HTTP
132 request. Thus, a "Proxy:"-header would set that environment variable!
134 Then, invoking curl_easy_perform() without having an URL set caused a crash.
136 - S. Moonesamy brought a patch that make curl use non-blocking connects on
137 windows when connection timeout is set, as it allows windows users to set
140 - Hirotaka Matsuyuki wrote a Ruby interface to libcurl!
142 - Cris Bailiff, Forrest Cahoon and Georg Horn work on the Perl interface.
144 - I've written a first shot at a Java interface to libcurl. Many thanks to
145 Daniel Marell for tirelessly answering to all my basic Java questions. It
146 works, but it is still very basic.
148 Daniel (10 April 2001)
149 - The progress display could get silly when doing multiple file transfers, as
150 it wasn't properly reset between transfers!
152 - Discussions with Cris Bailiff who writes a Perl interface to libcurl, made
153 me add CURLOPT_HEADERFUNCTION. It can be used to set a separate callback
154 function for writing headers. Previously you could only set a different FILE
155 * when headers are written from within libcurl.
157 Daniel (7 April 2001)
158 - Andrés García fixed a problem in curl_escape() and pointed out a flaw in
159 the curl_easy_setopt man page.
161 Daniel (6 April 2001)
162 - Adjusted the version code to properly display OpenSSL 0.9.6a. They sure
163 change their version define format often...
165 - curl_formfree() now accepts a NULL pointer without crashing!
169 Daniel (3 April 2001)
170 - Puneet Pawaia pointed out two serious problems. Libcurl would attempt to
171 read bad memory during situations when an (ftp) connection attempt failed.
172 Also, the lib/Makefile.vc6 was corrected.
174 - More investigations in the Location: following code made me realize that
175 it was not clean enough to work transparantly with persistent and non-
176 persistent connections. I think I've fixed it now.
178 Daniel (29 March 2001)
179 - Georg Horn mailed me some corrections for the Curl::easy perl interface.
181 - Experimental ftps:// support added. It is basically FTP over SSL for the
182 control connection. It still makes all data transfers going over unencrypted
183 connections. Rainer Weikusat's ftpd-ssl server hack supports this and I used
184 that to verify the functionality.
186 Daniel (27 March 2001)
187 - Guenole Bescon discovered that if you set a CURLOPT_TIMEOUT and then tried
188 to get a file from a site and it fails, the SIGALRM would still be sent
189 after the timeout-time, quite inexpectedly!
191 - I added an ftp transfer example to docs/examples/ and I also wrote a tiny
192 example makefile that can be used as a start when building one of the
197 Daniel (26 March 2001)
198 - Mohamed Lrhazi reported problems with 7.6.1 and persistent HTTP/1.0
199 connections (when the server replied a Connection: Keep-Alive) and this
200 problem was not properly dealt with in 7.7 either. A patch was posted to the
201 curl-and-php mailing list.
203 Daniel (24 March 2001)
204 - Colin Watson reported about a problem and brought a patch that corrected it,
205 which was about the man page and lines starting with a single quote (') in a
206 way that gnroff doesn't like.
208 Daniel (23 March 2001)
209 - Peter Bray reported correctly that the root makefile used make instead of
210 $(MAKE) for the test target.
212 - Corrected the Curl::easy perl interface to use curl_easy_setopt() and not
213 curl_setopt() which was removed in 7.7!
215 - S. Moonesamy provided updates on three documents (MANUAL, INSTALL and FAQ).
217 - When following a Location:, libcurl would sometimes write to the URL string
218 in a way it shouldn't. As the pointer is passed-in to libcurl from an
219 application, we can't be allowed to write to it. The particular bug report
220 from 'nk' that brought this up was because he had a read-only URL that then
221 caused a libcurl crash!
223 - No longer reads HEAD responses longer than to the last header. Previously,
224 curl would read the full reply if the connection was a "close" one.
226 - libcurl did re-use connections way too much. Doing "curl
227 http://www.{microsoft,ibm}.com" would make it re-use the connection which
228 made the second request return very odd results.
230 Daniel (22 March 2001)
231 - Edin Kadribasic made me aware that curl should not re-send POST requests
232 when following 302-redirects. I made 302 work like 303 which means curl uses
233 GET in the following request(s).
235 - libcurl now reset the "followed-location" counter on each invoke of
236 curl_easy_perform() as it otherwise would sum up all redirects on the same
237 connection and thus could reach the maxredirs counter wrongly.
239 - Jim Drash suggested curl_escape() should not re-encode what already looks
240 like an encoded sequence and I think that's a fair suggestion.
244 Daniel (22 March 2001)
245 - The configure script now fails with an error message if gethostbyname_r() is
246 detected but it couldn't figure out how to invoke it (what amount of
247 arguments it is supposed to get). Reports from Andrés García made me aware
250 - Talking with Jim Drash made me finally put the curl_escape and curl_unescape
251 functions in the curl.h include file and write man pages for them. The
252 escape function was modified to use the same interface as the unescape one
255 - No bug reports at all on the latest betas. Release time coming up.
259 Daniel (19 March 2001)
260 - Georg Ottinger reported problems with using -C together with -L in the sense
261 that the -C info got lost when it was redirected. I could not repeat this
262 problem on the 7.7 branch why I leave this for the moment. Test case 39 was
263 added to do exactly this, and it seems to do right.
265 - Christian Robottom Reis reported how his 7.7 beta didn't successfully do
266 form posts as elegantly as 7.6.1 did. Indeed, this was a flaw in the header
267 engine, as HTTP 1.1 has introduced a new 100 "transient" return code for PUT
268 and POST operations that I need to add support for. Section 8.2.3 in RFC2616
269 has all the details. Seems to work now!
271 Daniel (16 March 2001)
272 - After having experienced another machine break-down, we're back.
274 - Georg Horn's perl interface Curl::easy is now included in the curl release
275 archive. The perl/ directory is now present. Please help me with docs,
276 examples and updates you think fit.
278 - Made a new php/ directory in the release archive and moved the PHP examples
279 into a subdirectory in there. Not much PHP info yet, but I plan to. Please
280 help me here as well!
282 - Made libcurl return error if a transfer is aborted in the middle of a
283 "chunk". It actually enables libcurl to discover premature transfer aborts
284 even if the Content-Length: size is unknown.
286 Daniel (15 March 2001)
287 - Added --connect-timeout to curl, which sets the new CURLOPT_CONNECTTIMEOUT
288 option in libcurl. It limits the time curl is allowed to spend in the
289 connection phase. This differs from -m/--max-time that limits the entire
290 file transfer operation. Requested by Larry Fahnoe and others.
292 I also updated the curl.1 and curl_easy_setopt.3 man pages and removed the
297 Daniel (14 March 2001)
298 - Made curl grok IPv6 with HTTP proxies and got everything to compile nicely
299 again when ENABLE_IPV6 is set.
301 I need to remake things in the test suite. I can't test the FTP parts with
302 curl built for IPv6 as it uses a different set of FTP commands then!
304 - I fell onto a bug report on php.net (posted by Lars Torben Wilson) that was
305 a report meant for our project. Anyway, it said the .netrc parsing didn't
306 work as supposed, and as I agreed with Lars, I made the netrc parser use
307 getpwuid() to figure out the home directory of the effective user and try
308 that netrc. It still uses the environment variable HOME for those that don't
309 have that function or if the user doesn't return valid pwd info.
311 - Edin Kadribaic posted a bug report where he got a crash when a fetch with
312 user+password in the URL followed a Location: to a second URL (absolute,
313 without name+password). This bug has been around for a long while and
314 crashes due to a read at address zero. Fixed now. Wrote test case 38, that
317 - Modified the test suite's httpserver slightly to append all client request
318 data to its log file so that the test script now better can verify a range
319 of requests and not only the last one, as it did previously.
321 - Updated the curl man page with --random-file and --egd-file details.
325 Daniel (14 March 2001)
326 - Björn Stenberg provided similar fixes as Jörn did and some additional patches
327 for non-SSL compiles.
329 - I increased the interface number for libcurl as I've removed the low level
330 functions from the interface. I also took this opportunity to rename the
331 Curl_strequal function to curl_strequal and Curl_strnequal to
332 curl_strnequal, as they're public libcurl functions (even if they're still
335 This will make older programs not capable of using the new libcurl with
336 just a drop-in replacement.
338 - Jörn Hartroth updated stuff for win32 compiles:
339 o config-win32.h was fixed for socklen_t
340 o lib/ssluse.c had a bad #endif placement
341 o lib/file.c was made to compile on win32 again
342 o lib/Makefile.m32 was updated with the new files
343 o lib/libcurl.def matches the current interface state
345 Daniel (13 March 2001)
346 - It only took an hour or so before Jörn Hartroth found a problem in the
347 chunked transfer-encoding. Given his fine example-site, I could easily spot
348 the problem and when I re-read the spec (the part I have pasted in the top
349 of the http_chunks.h file), I realized I had made my state-machine slightly
350 wrong and didn't expect/handle the trailing CRLF that comes after the data
351 in each chunk (and those extra two bytes sure feel wasted).
353 Had to modify test case 34 to match this as well.
357 Daniel (13 March 2001)
358 - Added the policy stuff to the curl_easy_setopt man page for the two supported
361 - Implemented some support for the CURLOPT_CLOSEPOLICY option. The policies
362 CURLCLOSEPOLICY_LEAST_RECENTLY_USED and CURLCLOSEPOLICY_OLDEST are now
363 supported, and the "least recently used" is used as default if no policy
366 Daniel (12 March 2001)
367 - Added CURLOPT_RANDOM_FILE and CURLOPT_EGDSOCKET to libcurl for seeding the
368 SSL random engine. The random seeding support was also brought to the curl
369 client with the new options --random-file <file> and --egd-file <file>. I
370 need some people to really test this to know they work as supposed. Remember
371 that libcurl now informs (if verbose is on) if the random seed is considered
372 weak (HTTPS connections).
374 - Made the chunked transfer-encoding engine detected bad formatted data length
375 and return error if so (we can't possibly extract sensible data if this is
376 the case). Added a test case that detects this. Number 36. Now there are 60
379 - Added 5 new libcurl options to curl/curl.h that can be used to control the
380 persistent connection support in libcurl. They're also documented (fairly
381 thoroughly) in the curl_easy_setopt.3 man page. Three of them are now
382 implemented, although not really tested at this point... Anyway, the new
383 implemented options are named CURLOPT_MAXCONNECTS, CURLOPT_FRESH_CONNECT,
384 CURLOPT_FORBID_REUSE. The ones still left to write code for are:
385 CURLOPT_CLOSEPOLICY and its related option CURLOPT_CLOSEFUNCTION.
387 - Made curl (the actual command line tool) use the new libcurl 7.7 persistent
388 connection support by re-using the same curl handle for every specified file
389 transfer and after some more test case tweaking we have 100% test case OK.
390 I made some test cases return HTTP/1.0 now to make sure that works as well.
392 - Had to add 'Connection: close' to the headers of a bunch of test cases so
393 that curl behaves "old-style" since the test http server doesn't do multiple
394 connections... Now I get 100% test case OK.
396 - The curl.haxx.se site, the main curl mailing list and my personal email are
397 all dead today due to power blackout in the area where the main servers are
400 - I've made persistance work over a squid HTTP proxy. I find it disturbing
401 that it uses headers that aren't present in any HTTP standard though
402 (Proxy-Connection:) and that makes me feel that I'm now on the edge of what
403 the standard actually defines. I need to get this code excercised on a lot
404 of different HTTP proxies before I feel safe.
406 Now I'm facing the problem with my test suite servers (both FTP and HTTP)
407 not supporting persistent connections and libcurl is doing them now. I have
408 to fix the test servers to get all the test cases do OK.
410 Daniel (8 March 2001)
411 - Guenole Bescon reported that libcurl did output errors to stderr even if
412 MUTE and NOPROGRESS was set. It turned out to be a bug and happens if
413 there's an error and no ERRORBUFFER is set. This is now corrected.
417 Daniel (8 March 2001)
418 - "Transfer-Encoding: chunked" is no longer any trouble for libcurl. I've
419 added two source files and I've run some test downloads that look fine.
421 - HTTP HEAD works too, even on 1.1 servers.
423 Daniel (5 March 2001)
424 - The current 57 test cases now pass OK. It would suggest that libcurl works
425 using the old-style with one connection per handle. The test suite doesn't
426 handle multiple connections yet so there are no test cases for this.
428 - I patched the telnet.c heavily to not use any global variables anymore. It
429 should make it a lot nicer library-wise.
431 - The file:// support was modified slightly to use the internal connect-first-
434 Daniel (4 March 2001)
439 Daniel (4 March 2001)
440 - Now, there's even a basic check that a re-used connection is still alive
441 before it is assumed so. A few first tests have proven that libcurl will
442 then re-connect instead of re-use the dead connection!
444 Daniel (2 March 2001)
445 - Now they work intermixed as well. Major coolness!
447 - More fiddling around, my 'tiny' client I have for testing purposes now has
448 proved to download both FTP and HTTP with persistent connections. They do
449 not work intermixed yet though.
451 Daniel (1 March 2001)
452 - Wilfredo Sanchez pointed out a minor spelling mistake in a man page and that
453 curl_slist_append() should take a const char * as second argument. It does
456 Daniel (22 February 2001)
457 - The persistent connections start to look good for HTTP. On a subsequent
458 request, it seems that libcurl now can pick an already existing connection
459 if a suitable one exists, or it opens a new one.
461 - Douglas R. Horner mailed me corrections to the curl_formparse() man page
464 Daniel (20 February 2001)
465 - Added the docs/examples/win32sockets.c file for our windows friends.
467 - Linus Nielsen Feltzing provided brand new TELNET functionality and
470 * Negotiation is now passive. Curl does not negotiate until the peer does.
471 * Possibility to set negotiation options on the command line, currently only
472 XDISPLOC, TTYPE and NEW_ENVIRON (called NEW_ENV).
473 * Now sends the USER environment variable if the -u switch is used.
474 * Use -t to set telnet options (Linus even updated the man page, awesome!)
476 - Haven't done this big changes to curl for a while. Moved around a lot of
477 struct fields and stuff to make multiple connections get connection specific
478 data in separate structs so that they can co-exist in a nice way. See the
479 mailing lists for discussions around how this is gonna be implemented. Docs
480 and more will follow.
482 Studied the HTTP RFC to find out better how persistent connections should
483 work. Seems cool enough.
485 Daniel (19 February 2001)
486 - Bob Schader brought me two files that help set up a MS VC++ libcurl project
487 easier. He also provided me with an up-to-date libcurl.def file.
489 - I moved a bunch of prototypes from the public <curl/curl.h> file to the
490 library private urldata.h. This is because of the upcoming changes. The
491 low level interface is no longer being planned to become reality.
493 Daniel (15 February 2001)
494 - CURLOPT_POST is not required anymore. Just setting the POST string with
495 CURLOPT_POSTFIELDS will switch on the HTTP POST. Most other things in
496 libcurl already works this way, i.e they require only the parameter to
497 switch on a feature so I think this works well with the rest. Setting a NULL
498 string switches off the POST again.
500 - Excellent suggestions from Rich Gray, Rick Jones, Johan Nilsson and Bjorn
501 Reese helped me define a way how to incorporate persistent connections into
502 libcurl in a very smooth way. If done right, no change may have to be made
503 to older programs and they will just start using persistent connections when
506 Daniel (13 February 2001)
507 - Changed the word 'timeouted' to 'timed out' in two different error messages.
508 Suggested by Larry Fahnoe.
512 Daniel (9 February 2001)
513 - Frank Reid and Cain Hopwood provided information and research around a HTTPS
514 PUT/upload problem we seem to have. No solution found yet.
516 Daniel (8 February 2001)
517 - An interesting discussion is how to specify an empty password without having
518 curl ask for it interactively? The current implmentation takes an empty
519 password as a request for a password prompt. However, I still want to
520 support a blank user field. Thus, today if you enter "-u :" (without user
521 and password) curl will prompt for the password. Tricky. How would you
522 specify you want the prompt otherwise?
524 - Made the netrc parse result possible to use for other protocols than FTP and
525 HTTP (such as the upcoming TELNET fixes).
527 - The previously mentioned "MSVC++ problems" turned out to be a non-issue.
529 - Added a HTTP file upload code example in the docs/examples/ section on
532 - Adjusted the FTP response fix slightly.
536 Daniel (7 February 2001)
537 - S. Moonesamy found a flaw in the response reading function for FTP that
538 could make libcurl not get out of the loop properly when it should, if
539 libcurl got -1 returned when reading the socket.
541 - I found a similar mistake in http.c when using a proxy and reading the
542 results from the proxy connection.
544 Daniel (6 February 2001)
545 - S. Moonesamy pointed out that the VC makefile in src/ needed the libpath set
546 for the debug build to work.
548 - Daniel Gehriger stepped in to assist with the VC++ stuff Robert Weaver
549 brought up yesterday.
551 Daniel (5 February 2001)
552 - Jun-ichiro itojun Hagino brought a big patch that brings IPv6-awareness to
553 a bunch of different areas within libcurl.
555 - Robert Weaver told me about the problems the MS VC++ 6.0 compiler has with
556 the 'static' keyword on a number of libcurl functions. I might need to add a
557 patch that redefines static when libcurl is compiled with that compiler.
558 How do I know when VC++ compiles, anyone?
560 Daniel (4 February 2001)
561 - curl_getinfo() was extended with two new options:
562 CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD. They
563 return the full assumed content length of the transfer in the given
564 direction. The CURLINFO_CONTENT_LENGTH_DOWNLOAD will be the Content-Length:
565 size of a HTTP download. Added descriptions to the man page as well. This
566 was done after discussions with Bob Schader.
568 Daniel (3 February 2001)
569 - Ingo Ralf Blum provided another fix that makes curl build under the more
570 recent cygwin installations. It seems they've changed the preset defines to
571 not include WIN32 anymore.
575 Daniel (31 January 2001)
576 - Curl_read() and curl_read() now return a ssize_t for the size, as it had to
577 be able to return -1. The telnet support crashed due to this and there was a
578 possibility to weird behaviour all over. Linus Nielsen Feltzing helped me
581 - Added a configure.in check for a working getaddrinfo() if IPv6 is requested.
582 I also made the configure script feature --enable-debug which sets a couple
583 of compiler options when used. It assumes gcc.
585 Daniel (30 January 2001)
586 - I finally took a stab at the long-term FIXME item I've had on myself, and
587 now libcurl will properly work when doing a HTTP range-request that follows
588 a Location:. Previously that would make libcurl fail saying that the server
589 doesn't seem to support range requests.
591 Daniel (29 January 2001)
592 - I added a test case for the HTTP PUT resume thing (test case 33).
596 Daniel (29 January 2001)
597 - Yet another Content-Range change. Ok now? Bob Schader checks from his end
598 and it works for him.
600 Daniel (27 January 2001)
601 - So the HTTP PUT resume fix wasn't good. There should appearantly be a
602 Content-Range header when resuming a PUT.
604 - I noticed I broke the download-check that verifies that a resumed HTTP
605 download is actually resumed. It got broke because my new 'httpreq' field
606 in the main curl struct. I should get slapped. I added a test case for
607 this now, so I won't be able to ruin this again without noticing.
609 - Added a test case for content-length verifying when downloading HTTP.
611 - Made the progress meter title say if the transfer is being transfered. It
612 makes the output slightly better for resumes.
614 - When dealing with Location: and HTTP return codes, libcurl will not attempt
615 to follow the spirit of RFC2616 better. It means that when POSTing to a
616 URL that is being following to a second place, the standard will judge on
617 what to do. All HTTP codes except 303 and 305 will cause curl to make a
618 second POST operation. 303 will make a GET and 305 is not yet supported.
620 I also wrote two test cases for this POST/GET/Location stuff.
624 Daniel (26 January 2001)
625 - Lots of mails back and forth with Bob Schader finally made me add a small
626 piece of code in the HTTP engine so that HTTP upload resume works. You can
627 now do an operation like 'curl -T file -C <offset> <URL>' and curl will PUT
628 the ending part of the file starting at given offet to the specified URL.
632 Daniel (25 January 2001)
633 - I took hold of Rick Jones' question why we don't use recv() and send() for
634 reading/writing to the sockets and I've now modified the sread() and
635 swrite() macros to use them instead. If nothing else, they could be tested
636 in the next beta-round coming right up.
638 - Jeff Morrow found a problem with libcurl's usage of SSL_read() and supplied
639 his research results in how to fix this. It turns out we have to invoke the
640 function several times in some cases. The same goes for the SSL_write().
642 I made some rather drastic changes all over libcurl to make all writes and
643 reads get done on one single place so that this repeated-attempts thing
644 would only have to be implemented at one point.
646 - Rick Jones spotted that the 'total time' counter really didn't measure the
647 total time very accurate on subsecond levels.
649 - Johan Nilsson pointed out the need to more clearly specify that the timeout
650 value you set for a download is for the *entire* download. There's currently
651 no option available that sets a timeout for the connection phase only.
653 Daniel (24 January 2001)
654 - Ingo Ralf Blum submitted a series of patches required to get curl to compile
655 properly with cygwin.
657 - Robert Weaver posted a fix for the win32 section of the curl_getenv() code
658 that corrected a potential memory leak.
660 - Added comments in a few files in a sudden attempt to make the sources more
661 easy to read and understand!
663 Daniel (23 January 2001)
664 - Added simple IPv6 detection in the configure script and made the version
665 string add 'ipv6' to the enable section in that case. ENABLE_IPV6 will be
666 set if curl is compiled with IPv6 support enabled.
668 - Added a parser for IPv6-style specified IP-addresses in a URL. Thus, when
669 IPv6 gets enabled soon, we can use URLs like '[0::1]:80'...
671 - Made the URL globbing in the client possible to fail silently if there's an
672 error in the globbing. It makes it almost intuitive, so when you don't
673 follow the syntax rules, globbing is simply switched off and the raw string
676 I still think we'll get problems with IPv6-style IP-addresses when we *want*
677 globbing on parts of the URL as the initial part of the URL will for sure
678 seriously confuse the globber.
680 Daniel (22 January 2001)
681 - Björn Stenberg supplied a progress meter patch that makes it look better even
682 during slow starts. Previously it made some silly assumptions...
684 - Added two FTP tests for -Q and -Q - stuff since it was being discussed on
685 the mailing list. Had to correct the ftpserver.pl too as it bugged slightly.
687 Daniel (19 January 2001)
688 - Made the Location: parsers deal with any-length URLs. Thus I removed the last
689 code that restricts the length of URLs that curl supports.
691 - Added a --globoff test case (#28) and it quickly identified a memory problem
692 in src/main.c that I took care of.
696 Daniel (17 January 2001)
697 - Made the two former files lib/download.c and lib/highlevel.c become the new
698 lib/transfer.c which makes more sense. I also did the rename from Transfer()
699 to Curl_Transfer() in the other source files that use the transfer function
700 in the spirit of using Curl_ prefix for library-scoped global symbols.
702 Daniel (11 January 2001)
703 - Added -g/--globoff that switches OFF the URL globbing and thus enables {}[]
704 letters to be part of the URL. Do note that RFC2396 section 2.4.3 explicitly
705 mention these letters to be escaped. This was posted as a feature request by
706 Jorge Gutierrez and as a bug by Terry.
708 - Short options to curl that requires parameters can now be specified without
709 having the option and its parameter space separated. -ofile works as good as
710 -o file. -m20 is equal to -m 20. Do note that this goes for single-letter
711 options only, verbose --long-style options still must be separated with
712 space from their parameters.
714 Daniel (8 January 2001)
715 - Francis Dagenais reported that the SCO compiler still fails when compiling
716 curl due to that getpass_r() prototype. I've now put it around #ifndef
717 HAVE_GETPASS_R in an attempt to please the SCO systems.
719 - Made some minor corrections to get the client to cleanup properly and I made
720 the separator work again when getting multiple globbed URLs to stdout.
722 - Worked with Loic Dachary to get the make dist and make distcheck work
723 correctly. The 'maketgz' script is now using the automake generated 'make
724 dist' when creating release archives. Loic successfully made 'make rpms'
725 automatically build RPMs!
727 Loic Dachary (6 January 2001)
728 - Automated generation of rpm packages, no need to be root.
730 - make distcheck generates a proper distribution (EXTRA_DIST
731 in all Makefile.am modified to match FILES).
733 Daniel (5 January 2001)
734 - Huge client-side hack: now multiple URLs are supported. Any number of URLs
735 can be specified on the command line, and they'll all be downloaded. There
736 must be a corresponding -o or -O for each URL or the data will be written to
737 stdout. This needs more testing, time to release a 7.6-pre package.
739 - The krb4 support was broken in the release. Fixed now.
741 - Huge internal symbol rename operation. All non-static but still lib-internal
742 symbols should now be prefixed with 'Curl_' to prevent collisions with other
743 libs. All public symbols should be prefixed with 'curl_' and the rest should
744 be static and thus invisible to the outside world. I updated the INTERNALS
745 document to say this as well.
749 Daniel (4 January 2001)
750 - As Kevin P Roth suggested, I've added text to the man page for every command
751 line option and what happens when you specify that option more than
752 once. That hasn't been exactly crystal clear before.
754 - Made the configure script possible to run from outside the source-tree. For
755 odd reasons I can't build curl properly outside though. It has to do with
756 curl's dependencies on libcurl...
758 - Cut off all older (dated 1999 and earlier) CHANGES entries from this file.
759 The older piece is named CHANGES.0 and is added to the CVS repository in
760 case anyone would need it.
762 - I added another file 'CVS-INFO' to the CVS. It contains information about
763 files in the CVS that aren't included in release archives and how to build
764 curl when you get the sources off CVS.
766 - Updated CONTRIBUTE and FAQ due to the new license.
768 Daniel (3 January 2001)
769 - Renamed README.libcurl to LIBCURL
771 - Changed headers in all sources files to the new dual license concept of
772 curl: use the MIT/X derivate license *or* MPL. The LEGAL file was updated
773 accordingly and the MPL 1.1 and MIT/X derivate licenses are now part of the
776 Daniel (30 December 2000)
777 - Made all FTP commands get sent with the trailing CRLF in one single write()
778 as splitting them up seems to confuse at least some firewalls (FW-1 being
781 Daniel (19 December 2000)
782 - Added file desrciptor and FILE handle leak detection to the memdebug system
783 and thus I found and removed a file descriptor leakage in the ftp parts
784 that happened when you did PORTed downloads.
786 - Added an include <stdio.h> in <curl/curl.h> since it uses FILE *.
788 Daniel (12 December 2000)
789 - Multiple URL downloads with -O was still bugging. Not anymore I think or
790 hope, or at least I've tried... :-O
792 - Francois Petitjean fixed another -O problem
796 Daniel (11 December 2000)
797 - Cleaned up a few of the makefiles to use unix-style newlines only. As Kevin
798 P Roth found out, at least one CVS client behaved wrongly when it found
799 different newline conventions within the same file.
801 - Albert Chin-A-Young corrected the LDFLAGS use in the configure script for
804 Daniel (6 December 2000)
805 - Massimo Squillace correctly described how libcurl could use session ids when
806 doing SSL connections.
808 - James Griffiths found out that curl would crash if the file you specify with
809 -o is shorter than the URL! This took some hours to fully hunt down, but it
812 Daniel (5 December 2000)
813 - Jaepil Kim sent us makefiles that build curl using the free windows borland
814 compiler. The root makefile now accepts 'make borland' to build curl with
817 - Stefan Radman pointed out that the test makefiles didn't use the PERL
818 variable that the configure scripts figure out. Actually, you still need
819 perl in the path for the test suite to run ok.
821 - Rich Gray found numerous portability problems:
822 * The SCO compiler got an error on the getpass_r() prototype in getpass.h
823 since the curl one differed from the SCO one
824 * The HPUX compiler got an error because of how curl did the sigaction
825 stuff and used a define HPUX doesn't have (or need).
826 * A few more problems remain to be researched.
828 - Paul Harrington experienced a core dump using https. Not much details yet.
830 Daniel (4 December 2000)
831 - Jörn Hartroth fixed a problem with multiple URLs and -o/-O.
835 Daniel (1 December 2000)
836 - Craig Davison gave us his updates on the VC++ makefiles, so now curl should
837 build fine with the Microsoft compiler on windows too.
839 - Fixed the libcurl versioning so that we don't ruin old programs when
840 releasing new shared library interfaces.
842 Daniel (30 November 2000)
843 - Renamed docs/README.curl to docs/MANUAL to better reflect what the document
846 Daniel (29 November 2000)
847 - I removed a bunch of '#if 0' sections from the code. They only make things
848 harder to follow. After all, we do have all older versions in the CVS.
852 Daniel (28 November 2000)
853 - I filled in more error codes in the man page error code list that had been
856 - James Griffiths mailed me a fine patch that introduces the CURLOPT_MAXREDIRS
857 libcurl option. When used, it'll prevent location following more than the
858 set number of times. It is useful to break out of endless redirect-loops.
860 Daniel (27 November 2000)
861 - Added two test cases for file://.
863 Daniel (22 November 2000)
864 - Added the libcurl CURLOPT_FILETIME setopt, when set it tries to get the
865 modified time of the remote document. This is a special option since it
866 involves an extra set of commands on FTP servers. (Using the MDTM command
867 which is not in the RFC959)
869 curl_easy_getinfo() got a corresponding CURLINFO_FILETIME to get the time
870 after a transfer. It'll return a zero if CURLOPT_FILETIME wasn't used or if
871 the time wasn't possible to get.
873 --head/-I used on a FTP server will now present a 'Last-Modified:' header
874 if curl could get the time of the specified file.
876 - Added the option '--cacert [file]' to curl, which allows a specified PEM
877 file to be used to verify the peer's certificate when doing HTTPS
878 connections. This has been requested, rather recently by Hulka Bohuslav but
879 others have asked for it before as well.
881 Daniel (21 November 2000)
882 - Numerous fixes the test suite has brought into the daylight:
884 * curl_unescape() could return a too long string
885 * on ftp transfer failures, there could be memory leaks
886 * ftp CWD could use bad directory names
887 * memdebug now uses the mprintf() routines for better portability
888 * free(NULL) removed when doing resumed transfers
890 - Added a bunch of test cases for FTP.
892 - General cleanups to make less warnings with gcc -Wall -pedantic.
894 - I made the tests/ftpserver.pl work with the most commonly used ftp
895 operations. PORT, PASV, RETR, STOR, LIST, SIZE, USER, PASS all work now. Now
896 all I have to do is integrate the ftp server doings in the runtests.pl
897 script so that ftp tests can be run the same way http tests already run.
899 Daniel (20 November 2000)
900 - Made libcurl capable of dealing with any-length URLs. The former limit of
901 4096 bytes was a bit annoying when people wanted to use curl to really make
902 life tough on a web server. Now, the command line limit is the most annoying
903 but that can be circumvented by using a config file.
905 NOTE: there is still a 4096-byte limit on URLs extracted from Location:
908 - Corrected the spelling of 'resolve' in two error messages.
910 - Alexander Kourakos posted a bug report and a patch that corrected it! It
911 turned out that lynx and wget support lowercase environment variable names
912 where curl only looked for the uppercase versions. Now curl will use the
913 lowercase versions if they exist, but if they don't, it'll use the uppercase
916 Daniel (17 November 2000)
917 - curl_formfree() was added. How come no one missed that one before? I ran the
918 test suite with the malloc debug enabled and got lots of "nice" warnings on
919 memory leaks. The most serious one was this. There were also leaks in the
920 cookie handling, and a few errors when curl failed to connect and similar
921 things. More tests cases were added to cover up and to verify that these
922 problems have been removed.
924 - Mucho updated config file parser (I'm dead tired of all the bug reports and
925 weird behaviour I get on the former one). It works slightly differently now,
926 although I doubt many people will notice the differences. The main
927 difference being that if you use options that require parameters, they must
928 both be specified on the same line. With this new parser, you can also
929 specify long options without '--' and you may separate options and
930 parameters with : or =. It makes a config file line could look like:
932 user-agent = "foobar and something"
934 Parameters within quotes may contain spaces. Without quotes, they're
935 expected to be a single non-space word.
937 Had to patch the command line argument parser a little to make this work.
939 - Added --url as an option to allow the URL to be specified this way. It makes
940 way nicer config files. The previous way of specifying URLs in the config
941 file doesn't work anymore.
943 Daniel (15 November 2000)
944 - Using certain characters in usernames or passwords for HTTP authentication
945 failed. This was due to the mprintf() that had a silly check for letters,
946 and if they weren't isprint() they weren't outputed "as-is". This caused
947 passwords and usernames using '§' (for example) to fail.
951 Daniel (15 November 2000)
952 - 'tests/runtests.pl' now sorts the test cases properly when 'all' is used.
954 Daniel (14 November 2000)
955 - I fell over the draft-ietf-ftpext-mlst-12.txt Internet Draft titled
956 "Extensions to FTP" that contains a defined way how the ftp command SIZE
957 could be assumed to work.
959 - Laurent Papier posted a bug report about using "-C -" and FTP uploading a
960 file that isn't prsent on the server. The server might then return a 550 and
961 curl will fail. Should it instead as Laurent Papier suggests, start
962 uploading from the beginning as a normal upload?
964 Daniel (13 November 2000)
965 - Fixed a crash with the followlocation counter.
967 - While writing test cases for the test suite, I discovered an old limitation
968 that prevented -o and -T to be used at the same time. I removed this
969 immediately as this has no relevance in the current libcurl.
971 - Chris Faherty fixed a free-twice problem in lib/file.c
973 - I fixed the perl http server problem in the test suite.
977 Daniel (10 November 2000)
978 - I've (finally) started working on the curl test suite. It is in the new
979 tests/ directory. It requires sh and perl. There's a TCP server in perl and
980 most of the other stuff running a pretty simple shell script.
982 I've only made four test cases so far, but it proves the system can work.
984 - Laurent Papier noticed that curl didn't set TYPE when doing --head checks
985 for sizes on FTP servers. Some servers seem to return different sizes
986 depending on whether ASCII or BINARY is used!
988 - Laurent Papier detected that if you appended a FTP upload and everything was
989 already uploaded, curl would hang.
991 - Angus Mackay's getpass_r() in lib/getpass.c is now compliant with the
992 getpass_r() function it seems some systems actually have.
994 - Venkataramana Mokkapati detected a bug in the cookie parser and corrected
995 it. If the cookie was set for the full host name (domain=full.host.com),
996 the cookie was never sent back because of a faulty length comparison between
997 the set domain length and the current host name.
999 Daniel (9 November 2000)
1000 - Added a configure check for gethostbyname in -lsocket (OS/2 seems to need
1001 it). Added a check for RSAglue/rsaref for the cases where libcrypto is found
1002 but libssl isn't. I haven't verified this fix yet though, as I have no
1003 system that requires those libs to build.
1007 Daniel (7 November 2000)
1008 - Removed perror() outputs from getpass.c. Angus Mackay also agreed to a
1009 slightly modified license of the getpass.c file as the prototype was changed.
1011 Daniel (6 November 2000)
1012 - Added possibility to set a password callback to use instead of the built-in.
1013 They're controled with curl_easy_setopt() of course, the tags are
1014 CURLOPT_PASSWDFUNCTION and CURLOPT_PASSWDDATA.
1016 - Used T. Bharath's thinking and fixed the timers that showed terribly wrong
1017 times when location: headers were followed.
1019 - Emmanuel Tychon discovered that curl didn't really like user names only in
1020 the URL. I corrected this and I also fixed the since long living problem
1021 with URL encoded user names and passwords in the URLs. They should work now.
1023 Daniel (2 November 2000)
1024 - When I added --interface, the new error code that was added with it was
1025 inserted in the wrong place and thus all error codes from 35 and upwards got
1026 increased one step. This is now corrected, we're back at the previous
1027 numbers. All new exit codes should be added at the end.
1029 Daniel (1 November 2000)
1030 - Added a check for signal() in the configure script so that if sigaction()
1031 isn't present, we can use signal() instead.
1033 - I'm having a license discussion going on privately. The issue is yet again
1034 GPL-licensed programs that have problems with MPL. I am leaning towards
1035 making a kind of dual-license that will solve this once and for all...
1037 Daniel (31 October 2000)
1038 - Added the packages/ directory. I intend to let this contain some docs and
1039 templates on how to generate custom-format packages for various platforms.
1040 I've now removed the RPM related curl.spec files from the archive root.
1042 Daniel (30 October 2000)
1043 - T. Bharath brought a set of patches that bring new functionality to
1044 curl_easy_getinfo() and curl_easy_setopt(). Now you can request peer
1045 certificate verification with the *setopt() CURLOPT_SSL_VERIFYPEER option
1046 and then use the CURLOPT_CAINFO to set the certificate to verify the remote
1047 peer against. After an such an operation with a verification request, the
1048 *_getinfo() option CURLINFO_SSL_VERIFYRESULT will return information about
1049 whether the verification succeeded or not.
1051 Daniel (27 October 2000)
1052 - Georg Horn brought us a splendid patch that solves the long-standing
1053 annoying problem with timeouts that made curl exit with silly exit codes
1054 (which as been commented out lately). This solution is sigaction() based and
1055 of course then only works for unixes (and only those unixes that actually
1056 have the sigaction() function).
1058 Daniel (26 October 2000)
1059 - Björn Stenberg supplied a patch that fixed the flaw mentioned by Kevin Roth
1060 that made the password get echoed when prompted for interactively. The
1061 getpass() function (now known as my_getpass()) was also fixed to not use any
1062 static buffers. This also means we cannot use the "standard" getpass()
1063 function even for those systems that have it, since it isn't thread-safe.
1065 - Kevin Roth found out that if you'd write a config file with '-v url', the
1066 url would not be used as "default URL" as documented, although if you wrote
1067 it 'url -v' it worked! This has been corrected now.
1069 - Kevin Roth's idea of using multiple -d options on the same command line was
1070 just brilliant, and I couldn't really think of any reason why we shouldn't
1071 support it! The append function always append '&' and then the new -d
1072 chunk. This enables constructs like the following:
1074 curl -d name=daniel -d age=unknown foobarsite.com
1076 Daniel (24 October 2000)
1077 - I fixed the lib/memdebug.c source so that it compiles on Linux and other
1078 systems. It will be useful one day when someone else but me wants to run the
1079 memory debugging system.
1081 Daniel (23 October 2000)
1082 - I modified the maketgz and configure scripts, so that the configure script
1083 will fetch the version number from the include/curl/curl.h header files, and
1084 then the maketgz doesn't have to rebuild the configure script when I build
1087 - Björn Stenberg and Linus Nielsen correctly pointed out that curl was silly
1088 enough to not allow @-letters in passwords when they were specified with the
1089 -u or -U flags (CURLOPT_USERPWD and CURLOPT_PROXYUSERPWD). This also
1090 suggests that curl probably should url-decode the password piece of an URL
1091 so that you could pass an encoded @-letter there...
1093 Daniel (20 October 2000)
1094 - Yet another http server barfed on curl's request that include the port
1095 number in the Host: header always. I now only include the port number if it
1096 isn't the default (80 for HTTP, 443 for HTTPS). www.perl.com turned out to
1097 run one of those nasty servers.
1099 - The PHP4 module for curl had problems with referer that seems to have been
1100 corrected just yesterday. (Sterling Hughes of the PHP team confirmed this)
1102 Daniel (17 October 2000)
1103 - Vladimir Oblomov reported that the -Y and -y options didn't work. They
1104 didn't work for me either. This once again proves we should have that test
1107 - I finally changed the error message libcurl returns if you try a https://
1108 URL when the library wasn't build with SSL enabled. It will now return this
1110 "libcurl was built with SSL disabled, https: not supported!"
1112 I really hope it will make it a bit clearer to users where the actual
1117 Daniel (16 October 2000)
1118 - I forgot to remove some of the malloc debug defines from the makefiles in
1119 the release archive (of course).
1123 Daniel (16 October 2000)
1124 - The buffer overflow mentioned below was posted to bugtraq on Friday 13th.
1126 Daniel (12 October 2000)
1127 - Colin Robert Phipps elegantly corrected a buffer overflow. It could be used
1128 by an evil ftp server to crash curl. I took the opportunity of replacing a
1129 few other sprintf()s into snprintf()s as well.
1131 Daniel (11 October 2000)
1132 - Found some more memory leaks. This new simple memory debugger has turned out
1137 Daniel (9 October 2000)
1138 - Florian Koenig pointed out that the bool typedef in the curl/curl.h include
1139 file was breaking PHP 4.0.3 compiling. The bool typedef is not used in the
1140 public interface and was wrongly inserted in that header file.
1142 - Jörg Hartroth corrected a minor memory leak in the src/urlglob.c stuff. It
1143 didn't harm anyone since the memory is free()ed on exit anyway.
1145 - Corrected the src/main.c. We use the _MPRINTF_REPLACE #define to use our
1146 libcurl-printf() functions. This gives us snprintf() et al on all
1147 platforms. I converted the allocated useragent string to one that uses a
1150 - I've set an #if 0 section around the Content-Transfer-Encoding header
1151 generated in lib/formdata.c. This will hopefully make curl do more
1152 PHP-friendly multi-part posts.
1156 Daniel (9 October 2000)
1157 - Nico Baggus found out that curl's ability to force a ASCII download when
1158 using FTP was no longer working! I corrected this. This problem was probably
1159 introduced when I redesigned libcurl for version 7.
1161 - Georg Horn provided a source example that proved a memory leak in libcurl.
1162 I added simple memory debugging facilities and now we can make libcurl log
1163 all memory fiddling functions. An additional perl script is used to analyze
1164 the output logfile and to match malloc()s with free()s etc. The memory leak
1165 Georg found turned out to be the main cookie struct that cookie_cleanup()
1166 didn't free! The perl script is named memanalyze.pl and it is available in
1167 the CVS respository, not in the release archive.
1169 Daniel (8 October 2000)
1170 - Georg Horn found a GetHost() problem. It turned out it never assigned the
1171 pointer in the third argument properly! This could make a crash, or at best
1176 Daniel (6 October 2000)
1177 - Is the -F post following the RFC 1867 spec? We had this dicussion on the
1178 mailing list since it appears curl can't post -F form posts to a PHP
1179 receiver... I've been in touch with the PHP developers about this.
1181 - Domenico Andreoli found out that the long option '--proxy' wasn't working
1182 anymore! The option parser got confused when I added the --proxytunnel for
1183 7.3. This was indeed a very old flaw that hasn't turned up until now...
1185 - Jörn Hartroth provided patches, updated makefiles and two new files for DLL
1186 stuff on win32. He also pointed out that lib source files were compiled with
1187 -I../src which isn't only wrong but plain stupid!
1189 - Troels Walsted Hansen fixed a problem with HTTP resume. Curl previously used
1190 a local variable badly, that could lead to crashes.
1194 Daniel (4 October 2000)
1195 - More docs written. The curl_easy_getinfo.3 man page is now pretty accurate,
1196 as is the -w section in curl.1. I added two options to enable the user to
1197 get information about the received headers' size and the size of the HTTP
1198 request. T. Bharath requested them.
1200 Daniel (3 October 2000)
1201 - Corrected a sever free() before use in the new add_buffer_send()! ;-)
1205 Daniel (3 October 2000)
1206 - Jason S. Priebe sent me patches that changed the way curl issues HTTP
1207 requests. The entire request is now issued in one single shot. It didn't do
1208 this previously, and it has turned out that since the common browsers do it
1209 this way, some sites have turned out to work with browsers but not with
1210 curl! Although this is not a client-side problem, we want to be able to
1211 fully emulate browsers, and thus we have now adjusted the networking layer
1212 to slightly more appear as a browser. I adjusted Jason's patch, the faults
1215 Daniel (2 October 2000)
1216 - Anyone who ever uploaded data with curl on a slow link has noticed that the
1217 progess meter is updated very infrequently. That is due to the large buffer
1218 size curl is using. It reads 50Kb and sends it, updates the progress meter
1219 and loops. 50Kb is very much on a slow link, although it is pretty neat to
1222 I've now made an adjustment that makes curl use a 2Kb buffer for uploads to
1223 start with. If curl's average upload speed is faster than buffer size bytes
1224 per second, curl will increase the used buffer size up to max 50Kb. It
1225 should make the progress meter work better.
1229 Daniel (29 September 2000)
1230 - Ripped out the -w stuff from the library and put in the curl tool. It gets
1231 all the relevant info from the library using the new curl_easy_getinfo()
1234 - brad at openbsd.org mailed me a patch that corrected my kerberos mistake and
1235 removed a compiler warning from hostip.c that OpenBSD people get.
1237 Daniel (28 September 2000)
1238 - Of course (I should probably get punished somehow) I didn't properly correct
1239 the #include lines for the base64 stuff in the kerberos sources in the just
1240 released 7.3 package. They still include the *_krb.h files! Now, the error
1241 is sooo very easy to spot and fix so I won't bother with a quick bug fix
1242 release. I'll post a patch whenever one is needed instead. It'll be
1243 available in the CVS in a few minutes anyway.
1247 Daniel (28 September 2000)
1248 - Removed the base64_krb.[ch] files. They've now replaced the former
1251 Daniel (26 September 2000)
1252 - Updated some docs.
1254 - I changed the OpenSSL fix to work with older versions as well. The posted
1255 patch was only working with 0.9.6 and no older ones.
1259 Daniel (25 September 2000)
1260 - Erdmut Pfeifer informed us that curl didn't build with OpenSSL 0.9.6 and
1261 showed us what needed to get patched in order to make it build properly
1264 - Dirk Kruschewski found a bug in the cookie parser. I made an alternative
1265 approach to the solution Dirk himself suggested. The bug made a cookie
1266 header that didn't end with a trailing semicolon to not get parsed.
1268 - I've marked -c and -t deprecated now. If you use any of them, curl will tell
1269 you to use "-C -" or "-T -" instead. I don't think occupying two letters for
1270 nearly identical functions is good use. Also, -T - kind of follows the curl
1271 tradition of using - for stdin where a file name is expected.
1273 Daniel (23 September 2000)
1274 - Martin Hedenfalk provided the patch that finally made the krb4 ftp upload
1277 Daniel (21 September 2000)
1278 - The kerberos code is not quite thread-safe yet. There are a few more globals
1279 that need to be take care of. Let's get the upload working first!
1281 Daniel (20 September 2000)
1282 - Richard Prescott solved another name lookup buffer size problem. I took this
1283 opportunity to rewrite the GetHost() function. With these large buffer
1284 sizes, I think keeping them as local arrays quickly turn ugly. I now use
1285 malloc() to get the buffer memory. Thanks to this, I now can realloc() to a
1286 large buffer in case of demand (errno == ERANGE) in case a solution like
1287 that would become necessary. I still want to avoid that kind of nastiness.
1289 - Tried to compile and run curl on Linux for alpha and FreeBSD for alpha. Went
1290 as smooth as it could.
1292 - Added a docs/examples directory with two tiny example sources that show how
1293 to use libcurl. I hope users will supply me with more useful examples
1296 - Applied a patch by Jörn Hartroth to no longer use the word 'inteface' in the
1297 config struct in the src/main.c file since certain compilers have that word
1298 "reservered". I figure that is some kind of C++ decease.
1300 - Updated the curl.1 man page with --interface and --krb4.
1302 - Modified the base64Encode() function to work like the kerberos one, so that
1303 I could remove the use of that. There is no need for *two* base64 encoding
1308 Daniel (19 September 2000)
1309 - The kerberos4-layer source code that is much "influenced" by the original
1310 krb4 source code, through yafc into curl, was using quite a lot of global
1311 variables. libcurl can't work properly with globals like that why I had to
1312 clean up almost every function in the new security.c to make them use
1313 connection specific variables instead of the globals. I just hope I didn't
1314 destroy anything now... :-) configure updated, version string now reflects
1315 krb4 built-in. It almost works now. Only uploads are still being naughty.
1319 Daniel (18 September 2000)
1320 - Martin Hedenfalk supplied a major patch that introduces krb4-ftp support to
1321 curl. Martin is the primary author of the ftp client named yafc and he did
1322 not hesitate to help us implement this when I asked him. Many and sincere
1323 thanks to a splendid effort. It didn't even take many hours!
1325 - Stephen Kick supplied a big patch that introduces the --interface flag to
1326 the curl tool and CURLOPT_INTERFACE for libcurl. It allows you to specify an
1327 outgoing interface to use for your request. This may not work on all
1328 platforms. This needs testing.
1330 - Richard Prescott noticed that curl on Tru64 unix could core dumped if the
1331 name didn't resolve properly. This was due to the GetHost() function not
1332 returning an error even though it failed on some platforms!
1334 Daniel (15 September 2000)
1335 - Updated all sorts of documents in regards to the new proxytunnel support.
1339 Daniel (15 September 2000)
1340 - Kai-Uwe Rommel pointed out a problem in the httpproxytunnel stuff for ftp.
1341 Adjusted it. Added better info message when setting up the tunnel and the
1342 pasv message when doing the second connect.
1346 Daniel (15 September 2000)
1347 - libcurl now allows "httpproxytunnel" to an arbitrary host and port name. The
1348 second connection on ftp needed that.
1350 - TheArtOfHTTPScripting was corrected all over. I both type and spell really
1353 Daniel (14 September 2000)
1354 - -p/--proxytunnel was added to 'curl'. It uses the new
1355 CURLOPT_HTTPPROXYTUNNEL libcurl option that allows "any" protocol to tunnel
1356 through the specified http proxy. At the moment, this should work with ftp.
1358 Daniel (13 September 2000)
1359 - Jochen Schaeuble found that file:// didn't work as expected. Corrected this
1360 and mailed the patch to the mailing list.
1362 Daniel (7 September 2000)
1363 - I changed the #define T() in curl.h since it turned out it wasn't really
1364 a good symbol to use (when you compiled PHP with curl as a module, that
1365 define collided with some IMAP define or something). This was posted to the
1368 - I added extern "C" stuff in two header files to better allow libcurl usage
1369 in C++ sorces. Discussions on the libcurl list with Danny Horswell lead to
1374 Daniel (31 August 2000)
1375 - Albert Chin-A-Young fixed the configure script *again* and now it seems to
1376 detect Linux name resolving properly! (heard that before?)
1378 - Troels Walsted Hansen pointed out that downloading a file containing the
1379 letter '+' from an ftp server didn't work. It did work from HTTP though and
1380 the reason was my lame URL decoder.
1382 - I happened to notice that -I didn't at all work on ftp anymore. I corrected
1387 Daniel (30 August 2000)
1388 - Understanding AIX is a hard task. I believe I'll never figure out why they
1389 solve things so differently from the other unixes. Now, I'm left with the
1390 AIX 4.3 run-time warnings about duplicate symbols that according to this
1391 article (http://www.geocrawler.com/archives/3/405/1999/9/0/2593428/) is a
1392 libtool flaw. I tried the mentioned patch, although that stops the linking
1395 So, if I select to ignore the ld warnings there are compiler warnings that
1396 fill the screen pretty bad when curl compiles. It turns out that if I want
1397 to '#include <arpa/inet.h>', I can get tid of the warnings by include the
1398 following three include files before that one:
1400 #include <net/if_dl.h>
1401 #include <sys/mbuf.h>
1402 #include <netinet/if_ether.h>
1404 Now, is it really sane to add those include files before arpa/inet.h in all
1405 the source files that include it?
1407 Thanks to Albert Chin-A-Young at thewrittenword.com who gave me the AIX
1408 login to try everything on.
1410 Daniel (24 August 2000)
1411 - Jan Schmidt supplied us a new VC6 makefile for Windows as the previous one
1412 was not up to date but lacked several object files.
1414 - More work on the naming.
1416 - Albert Chin-A-Young provided a configure-check for large file support, as
1417 some systems seem to need that for them to work. Had to change the position
1418 for the config.h include file in every .c file in the libcurl dir...
1420 - As suggested on the mailing list (by Troy Engel), I did use a --data-binary
1421 option instead of the messy way I've left described below. It seems to
1422 work. The libcurl fix remained the same as yesterday.
1424 Daniel (23 August 2000)
1425 - Back on the -d stripping newlines thing. The 'plain post' thing was added
1426 when I had no thought of that one could actually post binary data with
1427 it. Now, I have to add this functionality in a graceful manner and I think
1428 I've managed to come up with a way: '-d @file;binary' will thus post the
1429 file binary, exactly as its contents are. It is implemented with a new
1430 *setopt() option (CURLOPT_POSTFIELDSIZE) to set the postfield size, since
1431 libcurl can't strlen() the data in these cases.
1433 - Albert Chin-A-Young made some very serious efforts and all the name
1434 resolving problems seem to have been sorted out now on all the platforms
1435 that previously showed them. I'll make another release now anyday because of
1438 - The FAQ was much enhanced when it comes to the licensing issues thanks to
1441 Daniel (21 August 2000)
1442 - Rick Welykochy pointed out a problem when you use -d to post and you want to
1443 keep the newlines, as curl strips them off as a bonus before posting...
1444 This needs to be addressed.
1448 Daniel (21 August 2000)
1449 - Got more people involved in the gethostbyname_r() mess. Caolan McNamara sent
1450 me configure-code that turned out to be very similar to my existing tests
1451 which only make me more sure I'm on the right path. I changed the order of
1452 the tests slightly, as it seems that some compilers don't yell error if a
1453 function is used with too many parameters. Thus, the first tested function
1454 will seem ok... Let's hope more compilers think of too-few parameters as bad
1455 manners, as we're now trying the functions in that order; fewer first. I
1456 should also add that Lars Hecking mailed me and volunteered to run tests on
1457 a few odd systems. Coalan is keeping his work over at
1458 http://www.csn.ul.ie/~caolan/publink/gethostbyname_r/. Might be handy in the
1461 Daniel (18 August 2000)
1462 - I noticed I hadn't increased the name lookup buffer in lib/ftp.c. I don't
1463 think this is the reason for the continued trouble though.
1465 Daniel (17 August 2000)
1466 - Fred Noz corrected my stupid mistakes in the gethostbyname_r() fluff. It
1467 should affect some AIX, Digital Unix and HPUX 10 systems.
1469 Daniel (15 August 2000)
1470 - Mathieu Legare compiled and build 7.1 without errors on both AIX 4.2 as well
1471 as AIX 4.3. Now why did problems occur before?
1473 - Fred Noz reported a -w/--write-out bug that caused it to malfunction when
1474 used combined with multiple URL retrievales. All but the first display got
1477 Daniel (11 August 2000)
1478 - Jason Priebe and an anonymous friend found some host names the Linux version
1479 of curl could not resolve. It turned out the buffer used to retrieve that
1480 information was too small. Fixed. One could argue about the usefulness of
1481 not having the slightest trace of a man page for gethostbyname_r() on my
1482 Linux Redhat installation...
1484 Daniel (10 August 2000)
1485 - Balaji S Rao was first in line to note the missing possibility to replace
1486 the Content-Type: and Content-Length: headers when doing -d posts. I added
1487 the possibility just now. It seems some people wants to do standard posts
1488 using custom Content-Types.
1490 Daniel (8 August 2000)
1491 - Mike Dowell correctly discovered that curl did not approve of URLs with no
1492 user name but password. As in 'http://:foo@haxx.se'. I corrected this.
1496 Daniel (7 August 2000)
1497 - My AIX 4 fix does not work. I need help from a AIX 4 hacker.
1499 - I added my new document in the docs directory. It is aimed to become a sort
1500 of tutorial on how to do HTTP scripting with curl.
1502 Daniel (4 August 2000)
1503 - Working with Rich Gray on compiling curl for lots of different platforms.
1504 My fix for AIX 3.2 was not good enough and was slightly changed, I had to
1505 move an include file before another, as is now described in the source.
1507 AIX 4.2 (4.X?) has different gethostbyname_r() and gethostbyaddr_r()
1508 functions that the configure script didn't check for and thus the compile
1509 broke with an error. I have now changed the gethostbyname_r() check in the
1510 configure file to support all three versions of both these functions. My
1511 implementation that uses the AIX-style is though not yet verified and I may
1512 get problems to fix it if it turns out to bug since I don't have access to
1513 any system using that.
1515 For problems like that, I made the configure script allow --disable-thread
1516 to completely switch off the check for threadsafe versions of a few
1517 functions and thus go with the "good old versions" that tend to work
1518 although will break thread-safeness for libcurl. Most people won't use
1519 libcurl for other things than curl though, and curl doesn't need a
1522 - Working on my big tutorial about HTTP scripting with curl.
1524 Daniel (1 August 2000)
1525 - Rich Gray spotted a problem in src/setup.h caused by a #define strequal()
1526 that was just a left-over from passed times. The strequal() is now a true
1527 function supplied by libcurl for a portable case insensitive string
1528 comparison. I added the prototypes in include/curl.h and removed the
1529 now obsolete #define.
1531 - Igor Khristophorov made a fix to allow resumed download from Sun's
1532 JavaWebServer/1.1.1. It seems that their server sends bad Content-Range
1535 - The makefiles forced a static library build, which is bad since we now use
1536 libtool and thus have excellent shared library support! Albert Chin-A-Young
1541 Daniel (1 August 2000)
1542 - Albert Chin-A-Young pointed out that 'make install' did not properly create
1543 the header include directory, why it failed to install the header files as
1544 it should. Automake isn't really equipped to deal with subdirectories
1545 without Makefiles in any nice way. I had to run ahead and add Makefiles in
1546 both include and include/curl before I managed to create a top-level
1547 makefile that succeeds in install everything properly!
1549 - Ok, no more "features" added now. Let's just verify that there's no major
1552 Daniel (31 July 2000)
1553 - Both Jeff Schasny and Ketil Froyn asked me how to tell curl not to send one
1554 of those internally generated headers. They didn't settle with the blank
1555 ones you could tell curl to use. I rewrote the header-replace stuff a
1556 little. Now, if you replace an internal header with your own and that new
1557 one is a blank header you will only remove the internal one and not get any
1558 blank. I couldn't figure out any case when you want that blank header.
1560 Daniel (29 July 2000)
1561 - It struck me that the lib used localtime() which is not thread-safe, so now
1562 I use localtime_r() in the systems that has it.
1564 - I went through this entire document and removed all email addresses and left
1565 names only. I've really made an effort to always note who brought be bug
1566 reports or fixes, but more and more people ask me to remove the email
1567 addresses since they become victims for spams this way. Gordon Beaton got me
1570 Daniel (27 July 2000)
1571 - Jörn Hartroth found out that when you specified a HTTP proxy in an
1572 environment variable and used -L, curl failed in the second fetch. I
1573 corrected this problem and posted a patch to the list. No need for an extra
1574 beta release just for this.
1578 Daniel (27 July 2000)
1579 - So, libtool replaced two of my files with symbolic links and I forgot to add
1580 the two new libtool files to the release archive (and they were added as
1581 symlinks as well!) This of course lead to that the configure script failed
1586 Daniel (25 July 2000)
1587 - Kristian Köhntopp <kris at koehntopp.de> brought a fix that makes libcurl
1588 libtoolified, just as we've wanted for a while now. He also made the
1589 recently added man pages get installed properly on 'make install' and some
1590 other nice cleanups.
1592 - In a discussion with Eetu Ojanen it struck me that if we use curl to get a
1593 page using a password, and that page then sends a Location: to another
1594 server that curl follows, curl will send the user name and password to that
1597 Now, I'll never be able to make curl do Location: following all that perfect
1598 and you're all sooner or later required to write a script to do several
1599 fetches when you're doing advanced stuff, but now I've modified curl to at
1600 least *only* send the user name and password to the original server. Which
1601 means that if get a page from server A with a password, that forwards curl
1602 to server B, curl won't use the password there. If server B then forwards
1603 curl back to server A again, the password will be used again.
1605 This is not a perfect implementation, as in a browser case it would only use
1606 the password if the left-prefix of the first path is the same. I just think
1607 that this fix prevents a somewhat lurky "security hole".
1609 As a side-note in this subject: HTTP passwords are sent in cleartext and
1610 will never be considered to be safe or secure. Use HTTPS for that.
1612 - As discussed on the mailing list, I converted the FTP response reading
1613 function into using select() which then allows timeouts (even under win32!)
1614 if the command-reply session gets too slow or dies completely. I made a
1615 default timeout on 3600 seconds unless anything else is specified, since I
1616 don't think anyone wants to wait more than that for a single character to
1619 - Torsten Foertsch <torsten.foertsch at gmx.net> brought a set of fixes for
1620 the rfc1867 form posts. He introduced 'name=<file' which brings a means to
1621 suuply very large text chunks read from the given file name. It differs from
1622 'name=@file' in the way that this latter thing is marked in the uploaded
1623 contents as a file upload, while the first is just text (as in a input or
1624 textarea field). Torsten also corrected a bug that would happen if you used
1625 %s or similar in a -F file name.
1627 - As discovered by Nico Baggus <Nico.Baggus at mail.ing.nl>, when transferring
1628 files to/from FTP using type ASCII curl should not expect the transfer to be
1629 the exact size reported by the server as the file size. Since ASCII may very
1630 well mean that the content is translated while transfered, the final size
1631 may very well differ. Therefor, curl now ignores the file size when doing
1632 ASCII transfers in FTP.
1634 Daniel (24 July 2000)
1635 - Added CURLOPT_PROXYPORT to the curl_easy_setopt() call to allow the proxy
1636 port number to be set separately from the proxy host name.
1638 - Andrew <andrew at ugh.net.au> pointed out a netrc manual bug.
1640 - The FTP transfer code now accepts a 250-code as well as the previously
1641 accepted 226, after a successful file transfer. Mohan <mnair at
1642 evergreen-funds.com> pointed this out.
1644 - The check for *both* nsl and socket was never added in the v7 configure.in
1645 when I moved the main branch. I re-added that check to configure.in. This was
1646 discovered by Rich Gray.
1648 - Howard, Blaise <Blaise.Howard at factiva.com> pointed out a missing free() in
1649 curl_disconnect() which of course meant libcurl ate memory.
1651 - Brian E. Gallew noted that the HTTP 'Host:' header curl sent did not
1652 properly include the port number if non-default ports were used. This should
1653 now have been fixed.
1655 - HTTP connect errors now return errors earlier. This was most notably causing
1656 problems when the HTTPS certificate had problems and later caused a crash.
1657 Many thanks to Gregory Nicholls <gnicholls at level8.com> for discovering
1658 and suggesting a fix...
1660 Daniel (21 June 2000)
1661 - After a "bug report" I received where the user was using both -F and -I in a
1662 HTTP request (it severly confused the library I should add), I added some
1663 checks to src/main.c that prevents setting more than one HTTP request
1664 command, no matter what the user wants! ;-)
1668 Daniel (20 June 2000)
1669 - I did a major replace in many files to use the new curl domain haxx.se
1670 instead of the previous one.
1672 - As Eetu Ojanen suggested, I finally took the step and now libcurl no longer
1673 makes a POST after it has followed a location. When the initial POST has
1674 been done, it'll turned into a GET for the further requests. This is only
1675 interesting when using -L/--location *and* doing a POST at the same time.
1677 While messing with this, I added another weird feature I call 'auto
1678 referer'. If you append ';auto' to the right of a given referer string (or
1679 only use that string as referer), libcurl will automatically set the
1680 previoud URL as refered when it follows a Location: and gets a succeeding
1683 - My hero Rich Gray found the very obscure FTP bug that happened to him only
1684 when passing through a particular firewall and using the PORT command. It
1685 turned out that PORT was the only command in the lib/ftp.c source that
1686 didn't send a proper \r\n sequence but instead used the faulty \n which as
1687 it seemed is supported by most major ftp servers... :-O
1691 Daniel (16 June 2000)
1692 - I had avoided this long enough now, so I moved the alternative progress bar
1693 stuff from the lib and added it to the client code. This is now using the
1694 recently added progress callback and it seems to work pretty much like
1695 before. Since it is only one progress bar and you and download and upload at
1696 the same time, this bar shows the combined progress of both directions. This
1697 code was just ported from the old place to this, Lars is still our saviour!
1698 ;-) This also made the documentation more accurate since I never removed
1699 this function from any docs! Although I now removed the CURLOPT_PROGRESSMODE
1700 from the library since the lib has only one internal progress meter and it
1701 will never get another. It is although likely that the internal one also
1702 will be moved to the client code in the future (when I have other means of
1703 getting the writeout data and move that too to the client).
1705 - I took the opportunity to verify that standard progress meter works and I
1706 found out it didn't get inited properly. Grrr. I corrected that as well.
1708 Daniel (15 June 2000)
1709 - I thought I'd better verify that the -F option still works in v7 and of
1710 course it didn't... :-/ Anyway, I had the problems I could discover
1711 corrected. About one month of beta testing and not a single person has used
1712 this feature with v7?
1714 - Björn correctly pointed out that the --progress-bar still doesn't work in
1717 Daniel (14 June 2000)
1718 - Tim Tassonis discovered that curl 7 didn't handle normal http POST as it
1719 should. I corrected this.
1723 Daniel (14 June 2000)
1724 - Björn Stenberg pointed out several problems (related to win32 compiling):
1725 lib/strequal.c had a bad #ifdef for one of the string comparisons (win32)
1726 src/main.c had several minor problems
1727 lib/makefile.m32 had getpass.[co] twice
1728 src/config-win32.h lacked the HAVE_FCNTL_H define
1729 both config-win32.h files now only set the HAVE_UNISTD_H define if the
1730 define MINGW32 is set, and I modified src/makefile.m32 and lib/makefile.m32
1735 Daniel (14 June 2000)
1736 - Applied Luong Dinh Dung's comments about a few win32 compile problems.
1738 - Applied Björn Stenberg's suggested fix that turns the win32 stdout to
1739 binary. It won't do it if the -B / --use-ascii option is used. That option
1740 is now an extended version of the previous -B /--ftp--ascii. The flag was
1741 already in use be the ldap as well so the new name fits pretty good. The
1742 libcyrl CURLOPT_TRANSFERTEXT was also introduced as an alias to the now
1743 obsolete CURLOPT_FTPASCII. Can't verify this fix myself as I have no win32
1746 Daniel (13 June 2000)
1747 - Luong Dinh Dung <dung at sch.bme.hu> found a problem in curl_easy_cleanup()
1748 since it free()ed the main curl struct *twice*. This is now corrected.
1750 Daniel (9 June 2000)
1751 - Updated the RESOURCES file, added a README.win32 file.
1753 Daniel (8 June 2000)
1754 - So I finally added the progress callback to the *setopt() options and it
1755 should work now. I don't have the energy to write any test program for it
1757 - Made the callback function typedefs public in curl/curl.h for comfort. Just
1758 in case anyone wanna fiddle with such pointers.
1759 - Updated the curl_easy_setopt() man page accordingly.
1763 Daniel (2 June 2000)
1764 - I noticed that when doing Location: following, we lost custom headers in all
1765 but the first request.
1766 - Removed the 'HttpPost' struct and moved the header stuff to the more generic
1768 - Added some better slist-cleanups in src/main.c
1772 Daniel (31 May 2000)
1773 - So I discovered that I released the 7.0.2beta without it being able to
1774 compile under Linux. gethostbyname_r() and gethostbyaddr_r() turned out to
1775 feature a different amount of arguments on different systems so I had to add
1776 a configure check for this and adjust the code slightly.
1780 Daniel (29 May 2000)
1781 - Corrected the bits.* assignments when using CURLOPT options that only
1782 toggles one of those bits.
1784 - Applied the huge patches from David LeBlanc <dleblanc at qnx.com> that add
1785 usage of the gethostbyname_r() and similar functions in case they're around,
1786 since that make libcurl much better threadsafe in many systems (such as
1787 solaris). I added the checks for these functions to the configure script.
1789 I can't explain why, but the inet_ntoa_r() function did not appear in my
1790 Solaris include files, I had to add my own include file for this for now.
1792 Daniel (22 May 2000)
1793 - Jörn Hartroth brought me fixes to make the win32 version compile properly as
1794 well as a rename of the 'interface' field in the urldata struct, as it seems
1795 to be reserved in some gcc versions!
1797 - Rich Gray struck back with yet some portability reports. Data General DG/UX
1798 needed a little fix in lib/ldap.c since it doesn't have RTLD_GLOBAL defined.
1799 More fixes are expected as a result of Richies very helpful work.
1803 Daniel (21 May 2000)
1804 - Updated lots of #defines, enums and variable type names in the library. No
1805 more weird URG or URLTAG prefixes. All types and names should be curl-
1806 prefixed to avoid name space clashes. The FLAGS-parameter to the former
1807 curl_urlget() has been converted into a bunch of flags to use in separate
1808 setopt calls. I'm still focusing on the easy-interface, as the curl tool is
1811 - Bjorn Reese has provided me with an asynchronous name resolver that I plan
1812 to use in upcoming versions of curl to be able to gracefully timeout name
1817 Daniel (18 May 2000)
1818 - Introduced LIBCURL_VERSION_NUM to the curl.h include file to better allow
1819 source codes to be dependent on the lib version. This define is now set to
1820 a dexadecimal number, with 8 bits each for major number, minor number and
1821 patch number. In other words, version 1.2.3 would make it 0x010203. It also
1822 makes a larger number a newer version.
1824 Daniel (17 May 2000)
1825 - Martin Kammerhofer correctly pointed out several flaws in the FTP range
1826 option. I corrected them.
1827 - Removed the win32 winsock init crap from the lib to the src/main.c file
1828 in the application instead. They can't be in the lib, especially not for
1829 multithreaded purposes.
1831 Daniel (16 May 2000)
1832 - Rewrote the src/main.c source to use the new easy-interface to libcurl 7.
1833 There is still more work to do, but the first step is now taken.
1834 <curl/easy.h> is the include file to use.
1836 Daniel (14 May 2000)
1837 - FTP URLs are now treated slightly different, more according to RFC 1738.
1838 - FTP sessions are now performed differently, with CWD commands to change
1839 directory instead of RETR/STOR/LIST with the full path. Discussions with
1840 Rich Gray made me notice these problems.
1841 - Janne Johansson discovered and corrected a buffer overflow in the
1843 - I had to add a lib/strequal.c file for doing case insensitive string
1844 compares on all platforms.
1846 Daniel (8 May 2000):
1847 - Been working lots on the new lib.
1848 - Together with Rich Gray, I've tried to adjust the configure script to work
1849 better on the NCR MP-RAS Unix.
1851 Daniel (2 May 2000):
1852 - Albert Chin-A-Young pointed out that I had a few too many instructions in
1853 configure.in that didn't do any good.
1855 Daniel (24 April 2000):
1856 - Added a new paragraph to the FAQ about what to do when configure can't
1857 find OpenSSL even though it is installed. Supplied by Bob Allison
1859 Daniel (12 April 2000):
1860 - Started messing around big-time to convert the old library interface to a
1863 Daniel (8 April 2000):
1864 - Made the progress bar look better for file sizes between 9999 kilobytes
1865 and 100 megabytes. They're now displayed XX.XM.
1866 - I also noticed that ftp fetches through HTTP proxies didn't add the user
1867 agent string. It does now.
1868 - Habibie <habibie at MailandNews.com> supplied a pretty good way to build RPMs
1869 on a Linux machine. It still a) requires me to be root to do it, b) leaves
1870 the rpm packages laying at some odd place on my disk c) doesn't work to
1871 build the ssl version of curl since I didn't install openssl from an rpm
1872 package so now the rpm crap thinks I don't have openssl and refuses to build
1873 a package that depends on ssl... Did I mention I don't get along with RPM?
1874 - Once again I received a bug report about autoconf not setting -L prior to -l
1875 on the command line when checking for libs. In this case it made the native
1876 cc compiler on Solaris 7 to fail the OpenSSL check. This has previously been
1877 reported to cause problems on HP-UX and is a known flaw in autoconf 2.13. It
1878 is a pity there's no newer release around...
1880 Daniel (4 April 2000):
1881 - Marco G. Salvagno supplied me with two fixes that
1882 appearantly makes the OS/2 port work better with multiple URLs.
1884 Daniel (2 April 2000):
1885 - Another Location: fix. This time, when curl connected to a port and then
1886 followed a location with an absolute URL to another port, it misbehaved.
1888 Daniel (27 March 2000):
1889 - H. Daphne Luong pointed out that curl was wrongly
1890 messing up the proxy string when fetching a document through a http proxy,
1891 which screwed up multiple fetches such as in location: followings.
1893 Daniel (23 March 2000):
1894 - Marco G. Salvagno corrected my badly applied patch he
1895 actually already told me about!
1897 - H. Daphne Luong brought me a fix that now makes curl
1898 ignore select() errors in the download if errno is EINTR, which turns out to
1899 happen every now and then when using libcurl multi-threaded...
1901 Daniel (22 March 2000):
1902 - Wham Bang supplied a couple of win32 fixes. HAVE_UNAME
1903 was accidentally #defined in config-win32.h, which it shouldn't have been.
1904 The HAVE_UNISTD_H is not defined when compiling with the Makefile.vc6
1905 makefile for MS VC++.
1907 Daniel (21 March 2000):
1908 - I removed the AC_PROG_INSTALL macro from configure.in, since it appears that
1909 one of the AM_* macros searches for a BSD compatible install already. Janne
1910 Johansson made me aware of this.
1914 Daniel (21 March 2000):
1915 - Paul Harrington quickly pointed out to me that 6.5.1
1916 crashes hard. I upload 6.5.2 now as quickly as possible! The problem was
1917 the -D adjustments in src/main.c.
1921 Daniel (20 March 2000):
1922 - An anonymous post on sourceforge correctly pointed out a possible buffer
1923 overflow in the curl_unescape() function for URL conversions. The main
1924 problem with this bug is that the ftp download uses that function and this
1925 single- byte overflow could lead to very odd bugs (as one reported by Janne
1928 Daniel (19 March 2000):
1929 - Marco G. Salvagno supplied me with a series of patches
1930 that now allows curl to get compiled on OS/2. It even includes a section in
1931 the INSTALL file. Very nice job!
1933 Daniel (17 March 2000):
1934 - Wham Bang supplied a patch for the lib/Makefile.vc6
1935 file. We still need some fixes for the config-win32.h since it appears that
1936 VC++ and mingw32 have different opinions about (at least) unistd.h's
1939 Daniel (15 March 2000):
1940 - I modified the -D/--dump-header workings so that it doesn't write anything
1941 to the file until it needs to. This way, you can actually use -b and -D
1942 on the same file if you want repeated invokes to store and read the cookies
1943 in that one single file.
1945 - Poked around in lots of texts. Added the BUGS file for bug reporting stuff.
1946 Added the classic HTTP POST question to the FAQ, removed some #ifdef WIN32
1947 stuff from the sources (they're covered by the config-win32.h now).
1949 - Pascal Gaudette fixed a missing ldap.c problem in the
1950 Makefile.vc6 file. He also addressed a problem in src/config-win32.h.
1952 Daniel (14 March 2000):
1953 - Paul Harrington pointed out that the 'http_code' variable in the -w output
1954 was never written. I fixed it now.
1956 - Janne Johansson reported the complaints that OpenBSD does
1957 when getdate.c #includes malloc.h. It claims stdlib.h should be included
1958 instead. I added #ifdef HAVE_MALLOC_H code in getdate.y and two checks in
1959 the configure.in for malloc.h and stdlib.h.
1963 Daniel (13 March 2000):
1964 - <curl at spam.wolvesbane.net> pointed out that the way curl sent cookies in a
1965 single line wasn't enjoyed by IIS4.0 servers. In my view, that is not what
1966 the standards say, but I added a white space between the name/value pairs to
1967 perhaps make them work better.
1969 - Added the perl check back in the configure.in again since the mkhelp.pl
1972 - Made some beautifications in the curl man page.
1974 Daniel (3 March 2000):
1975 - Jörn helped me update the config-win32.h files with HAVE_SETVBUF and
1978 Daniel (3 March 2000):
1979 - Uploaded the 6.5pre2 package.
1981 Daniel (2 March 2000):
1982 - Removed the perl-programs from the distribution, they never made many people
1983 happy and I'll still keep them available on the web.
1985 - Added the -w and -N stuff to the man page. Documented the new progress meter
1986 display in README.curl.
1988 - Jörn Hartroth, Chris <cbayliss at csc.come> and Ulf
1989 Möller from the openssl development team helped bringing me the details for
1990 fixing an OpenSSL usage flaw. It became apparent when they released openssl
1991 0.9.5 since that barfed on curl's bad behavior (not seeding a random number
1994 - Yet another option: -N/--no-buffer disables buffering in the output stream.
1995 Probably most useful for very slow transfers when you really want to get
1996 every byte curl receives within some preferred time. Andrew <tmr at gci.net>
1999 - Damien Adant mailed me his fixes for making curl compile on Ultrix.
2001 Daniel (24 February 2000):
2002 - Applied Jörn Hartroth's fixes for config-win32.h and lib/Makefile.w32.
2004 I should also make a note here, if nothing else to myself, that when using
2005 the %-syntax for variables in DOS command prompts, you must use two %-
2006 letters for each one since that is an escape letter there! Maybe I should
2007 use another letter instead!
2009 - Added more variables to -w:
2017 - Made -w@filename read the syntax from a file and -w@- reads the syntax from
2018 stdin in the good old "standard" curl way.
2020 Daniel (22 February 2000):
2021 - Released a 6.5pre1 version to get some test and user feedback.
2023 Daniel (21 February 2000):
2025 - I added the -w/--write-out flag and some variables to go with it. -w is a
2026 single string, whatever you enter there will be written out when curl has
2027 completed a successful request. There are some variable substitutions and
2028 they are specified as '%{variable}' (without the quotes). Variables that
2029 exist as of this moment are:
2031 total_time - total transfer time in seconds (with 2 decimals)
2032 size_download - total downloaded amount of bytes
2033 size_upload - total uploaded amount of bytes
2034 speed_download - the average speed of the entire download
2035 speed_upload - the average speed of the entire upload
2037 I will of course add more variables, but I need input on these and others.
2039 - It struck me that the -# progress bar will be hard to just apply on the new
2040 progress bar concept. I need some feedback on this before that'll get re-
2043 Daniel (16 February 2000):
2044 - Jörn Hartroth brought me some fixes for the progress meter and I continued
2045 working on it. It seems to work for http download, http post, ftp download
2046 and ftp upload. It should be a pretty good test it works generally good.
2048 - Still need to add the -# progress bar into the new style progress interface.
2050 - Gonna have a go at my new output option parameter next.
2052 Daniel (15 February 2000):
2053 - The progress meter stuff is slowly taking place. There's more left before it
2054 is working ok and everything is tested, but we're reaching there. Slowly!
2056 Daniel (11 February 2000):
2057 - Paul Marquis fixed the config file parsing of curl to
2058 deal with any-length lines, removing the previous limit of 4K.
2060 - Eetu Ojanen's suggestion of supporting the @-style for -b
2061 is implemented. Now -b@<filename> works as well as the old style. -b@- also
2062 similarly reads the cookies from stdin.
2064 - Reminder: -D should not write to the file until it needs to, in the same way
2065 -o does. That would enable curl to use -b and -D on the same file...
2067 - Ellis Pritchard made getdate.y work for MacOS X.
2069 - Paul Harrington helped me out finding the crash in the
2070 cookie parser. He also pointed out curl's habit of sending empty cookies to
2073 Daniel (8 February 2000):
2074 - Ron Zapp corrected a problem in src/urlglob.c that
2075 prevented curl from getting compiled on sunos 4. The problem had to do
2076 with the difference in sprintf() return code types.
2078 - Transfer() should now be able to download and upload simultaneously. Let's
2079 do some progress meter fixes later this week.
2081 Daniel (31 January 2000):
2082 - Paul Harrington found another core dump in the cookie
2083 parser. Curl doesn't properly recognize the 'version' keyword and I think
2084 that is what caused this. I need to refresh some specs on cookies and see
2085 what else curl lacks to improve this a bit more once and for all.
2087 RFC 2109 clearly specifies how cookies should be dealt with when they are
2088 compliant with that spec. I don't think many servers are though...
2090 - Mark W. Eichin found that while curl is uploading a form
2091 to a web site, it doesn't read incoming data why it'll hang after a while
2092 since the socket "pipe" becomes full.
2094 It took me two hours to rewrite Download() and Upload() into the new
2095 single function Transfer(). It even seems to work! More testing is required
2096 of course... I should get the header-sending together in a kind of queue
2097 and let them get "uploaded" in Transfer() as well.
2099 - Zhibiao Wu pointed out a curl bug in the location: area,
2100 although I did not get a reproducible way to do this why I have to wait
2101 with fixing anything.
2103 - Bob Schader suggested I should implement resume
2104 support for the HTTP PUT operation, and as I think it is a valid suggestion
2107 Daniel (25 January 2000):
2108 - M Travis Obenhaus pointed out a manual mixup with -y and -Y that was
2111 - Jens Schleusener pointed out a problem to compile
2112 curl on AIX 4.1.4 and gave me a solution. This problem was already fixed
2113 by Jörn's recent #include modifications!
2115 Daniel (19 January 2000):
2116 - Oskar Liljeblad pointed out and corrected a problem
2117 in the Location: following system that made curl following a location: to a
2118 different protocol to fail.
2120 At January 31st I re-considered this fix and the surrounding source code. I
2121 could not really see that the patch did any difference, why I removed it
2122 again for further research and debugging. (It disabled location: following
2123 on server not running on default ports.)
2125 - Jörn Hartroth brought a fix that once again
2126 made it possible to select progress bar.
2128 - Jörn also fixed a few include problems.
2132 Daniel (17 January 2000):
2133 - Based on suggestions from Björn Stenberg, I made the
2134 progress deal better with larger files and added a "Time" field which shows
2135 the time spent on the download so far.
2136 - I'm now using the CVS repository on sourceforge.net, which also allows web
2137 browsing. See http://curl.haxx.nu.
2139 Daniel (10 January 2000):
2140 - Renumbered some enums in curl/curl.h since tag number 35 was used twice!
2141 - Added "postquote" support to the ftp section that enables post-ftp-transfer
2143 - Now made the -Q/--quote parameter recognize '-' as a prefix, which means
2144 that command will be issued AFTER a successful ftp transfer. This can of
2145 course be used to delete or rename a file after it has been uploaded or
2146 downloaded. Use your imagination! ;-)
2147 - Since I do the main development on solaris 2.6 now, I had to download and
2148 install GNU groff to generate the hugehelp.c file. The solaris nroff cores
2149 on the man page! So, in order to make the solaris configure script find a
2150 better result I made gnroff get checked prior to the regular nroff.
2151 - Added all the curl exit codes to the man page.
2152 - Jim Gallagher properly tracked down a bug in autoconf
2153 2.13. The AC_CHECK_LIB() macro wrongfully uses the -l flag before the -L
2154 flag to 'ld' which causes the HP-UX 10.20 flavour to fail on all libchecks
2155 and therefore you can't make the configure script find the openssl libs!
