History of Changes
Daniel (29 July 2000)
- It struck me that the lib used localtime() which is not thread-safe, so now
I use localtime_r() in the systems that has it.
- I went through this entire document and removed all email addresses and left
names only. I've really made an effort to always note who brought be bug
reports or fixes, but more and more people ask me to remove the email
addresses since they become victims for spams this way.
Daniel (27 July 2000)
- Jörn Hartroth found out that when you specified a HTTP proxy in an
environment variable and used -L, curl failed in the second fetch. I
corrected this problem and posted a patch to the list. No need for an extra
beta release just for this.
Version 7.0.10beta
Daniel (27 July 2000)
- So, libtool replaced two of my files with symbolic links and I forgot to add
the two new libtool files to the release archive (and they were added as
symlinks as well!) This of course lead to that the configure script failed
on 7.0.9...
Version 7.0.9beta
- Kristian Köhntopp <kris at koehntopp.de> brought a fix that makes libcurl

libtoolified, just as we've wanted for a while now. He also made the
recently added man pages get installed properly on 'make install' and some
other nice cleanups.
- In a discussion with Eetu Ojanen it struck me that if we use curl to get a
page using a password, and that page then sends a Location: to another
server that curl follows, curl will send the user name and password to that
server as well.
Now, I'll never be able to make curl do Location: following all that perfect
and you're all sooner or later required to write a script to do several
fetches when you're doing advanced stuff, but now I've modified curl to at
least *only* send the user name and password to the original server. Which
means that if get a page from server A with a password, that forwards curl
to server B, curl won't use the password there. If server B then forwards
curl back to server A again, the password will be used again.
This is not a perfect implementation, as in a browser case it would only use
the password if the left-prefix of the first path is the same. I just think
that this fix prevents a somewhat lurky "security hole".
As a side-note in this subject: HTTP passwords are sent in cleartext and
will never be considered to be safe or secure. Use HTTPS for that.
- As discussed on the mailing list, I converted the FTP response reading
function into using select() which then allows timeouts (even under win32!)
if the command-reply session gets too slow or dies completely. I made a
default timeout on 3600 seconds unless anything else is specified, since I
don't think anyone wants to wait more than that for a single character to
get received...
- Torsten Foertsch <torsten.foertsch at gmx.net> brought a set of fixes for
the rfc1867 form posts. He introduced 'name=<file' which brings a means to
suuply very large text chunks read from the given file name. It differs from
'name=@file' in the way that this latter thing is marked in the uploaded
contents as a file upload, while the first is just text (as in a input or
textarea field). Torsten also corrected a bug that would happen if you used
%s or similar in a -F file name.
- As discovered by Nico Baggus <Nico.Baggus at mail.ing.nl>, when transferring
files to/from FTP using type ASCII curl should not expect the transfer to be
the exact size reported by the server as the file size. Since ASCII may very
well mean that the content is translated while transfered, the final size
may very well differ. Therefor, curl now ignores the file size when doing
ASCII transfers in FTP.

Daniel (24 July 2000)
- Added CURLOPT_PROXYPORT to the curl_easy_setopt() call to allow the proxy
port number to be set separately from the proxy host name.
- Andrew <andrew at ugh.net.au> pointed out a netrc manual bug.
- The FTP transfer code now accepts a 250-code as well as the previously
accepted 226, after a successful file transfer. Mohan <mnair at
evergreen-funds.com> pointed this out.
- The check for *both* nsl and socket was never added in the v7 configure.in
when I moved the main branch. I re-added that check to configure.in. This was
discovered by Rich Gray.
- Howard, Blaise <Blaise.Howard at factiva.com> pointed out a missing free() in
curl_disconnect() which of course meant libcurl ate memory.
- Brian E. Gallew noted that the HTTP 'Host:' header curl sent did not
properly include the port number if non-default ports were used. This should
now have been fixed.
- HTTP connect errors now return errors earlier. This was most notably causing
problems when the HTTPS certificate had problems and later caused a crash.
Many thanks to Gregory Nicholls <gnicholls at level8.com> for discovering
and suggesting a fix...
Daniel (21 June 2000)
- After a "bug report" I received where the user was using both -F and -I in a
HTTP request (it severly confused the library I should add), I added some
checks to src/main.c that prevents setting more than one HTTP request
command, no matter what the user wants! ;-)
Version 7.0.8beta
- I did a major replace in many files to use the new curl domain haxx.se
instead of the previous one.
- As Eetu Ojanen suggested, I finally took the step and now libcurl no longer
makes a POST after it has followed a location. When the initial POST has
been done, it'll turned into a GET for the further requests. This is only
interesting when using -L/--location *and* doing a POST at the same time.
While messing with this, I added another weird feature I call 'auto
referer'. If you append ';auto' to the right of a given referer string (or
only use that string as referer), libcurl will automatically set the
previoud URL as refered when it follows a Location: and gets a succeeding
document.
- My hero Rich Gray found the very obscure FTP bug that happened to him only
when passing through a particular firewall and using the PORT command. It
turned out that PORT was the only command in the lib/ftp.c source that
didn't send a proper \r\n sequence but instead used the faulty \n which as
it seemed is supported by most major ftp servers... :-O

Daniel (16 June 2000)
- I had avoided this long enough now, so I moved the alternative progress bar
stuff from the lib and added it to the client code. This is now using the
recently added progress callback and it seems to work pretty much like
before. Since it is only one progress bar and you and download and upload at
the same time, this bar shows the combined progress of both directions. This
code was just ported from the old place to this, Lars is still our saviour!
;-) This also made the documentation more accurate since I never removed
this function from any docs! Although I now removed the CURLOPT_PROGRESSMODE
from the library since the lib has only one internal progress meter and it
will never get another. It is although likely that the internal one also
will be moved to the client code in the future (when I have other means of
getting the writeout data and move that too to the client).
- I took the opportunity to verify that standard progress meter works and I
found out it didn't get inited properly. Grrr. I corrected that as well.
Daniel (15 June 2000)
- I thought I'd better verify that the -F option still works in v7 and of
course it didn't... :-/ Anyway, I had the problems I could discover
corrected. About one month of beta testing and not a single person has used
this feature with v7?
- Björn correctly pointed out that the --progress-bar still doesn't work in
v7. Hm.
Daniel (14 June 2000)
- Tim Tassonis discovered that curl 7 didn't handle normal http POST as it
should. I corrected this.
Version 7.0.6beta
Daniel (14 June 2000)
- Björn Stenberg pointed out several problems (related to win32 compiling):
lib/strequal.c had a bad #ifdef for one of the string comparisons (win32)
src/main.c had several minor problems
lib/makefile.m32 had getpass.[co] twice
src/config-win32.h lacked the HAVE_FCNTL_H define
both config-win32.h files now only set the HAVE_UNISTD_H define if the
define MINGW32 is set, and I modified src/makefile.m32 and lib/makefile.m32
to set it.
Version 7.0.5beta
Daniel (14 June 2000)
- Applied Luong Dinh Dung's comments about a few win32 compile problems.
- Applied Björn Stenberg's suggested fix that turns the win32 stdout to
binary. It won't do it if the -B / --use-ascii option is used. That option
is now an extended version of the previous -B /--ftp--ascii. The flag was
already in use be the ldap as well so the new name fits pretty good. The
libcyrl CURLOPT_TRANSFERTEXT was also introduced as an alias to the now
obsolete CURLOPT_FTPASCII. Can't verify this fix myself as I have no win32
compiler around.
Daniel (13 June 2000)
- Luong Dinh Dung <dung at sch.bme.hu> found a problem in curl_easy_cleanup()
since it free()ed the main curl struct *twice*. This is now corrected.
Daniel (9 June 2000)
- Updated the RESOURCES file, added a README.win32 file.

Daniel (8 June 2000)
- So I finally added the progress callback to the *setopt() options and it
should work now. I don't have the energy to write any test program for it
right now.
- Made the callback function typedefs public in curl/curl.h for comfort. Just
in case anyone wanna fiddle with such pointers.
- Updated the curl_easy_setopt() man page accordingly.
Version 7.0.4beta
Daniel (2 June 2000)
- I noticed that when doing Location: following, we lost custom headers in all
but the first request.
- Removed the 'HttpPost' struct and moved the header stuff to the more generic
curl_slist.
- Added some better slist-cleanups in src/main.c
Version 7.0.3beta
Daniel (31 May 2000)
- So I discovered that I released the 7.0.2beta without it being able to
compile under Linux. gethostbyname_r() and gethostbyaddr_r() turned out to
feature a different amount of arguments on different systems so I had to add
a configure check for this and adjust the code slightly.
Version 7.0.2beta
Daniel (29 May 2000)
- Corrected the bits.* assignments when using CURLOPT options that only
toggles one of those bits.
- Applied the huge patches from David LeBlanc <dleblanc at qnx.com> that add
usage of the gethostbyname_r() and similar functions in case they're around,
since that make libcurl much better threadsafe in many systems (such as
solaris). I added the checks for these functions to the configure script.
I can't explain why, but the inet_ntoa_r() function did not appear in my
Solaris include files, I had to add my own include file for this for now.
- Jörn Hartroth brought me fixes to make the win32 version compile properly as
well as a rename of the 'interface' field in the urldata struct, as it seems
to be reserved in some gcc versions!
- Rich Gray struck back with yet some portability reports. Data General DG/UX
needed a little fix in lib/ldap.c since it doesn't have RTLD_GLOBAL defined.
More fixes are expected as a result of Richies very helpful work.
Daniel (21 May 2000)
- Updated lots of #defines, enums and variable type names in the library. No
more weird URG or URLTAG prefixes. All types and names should be curl-
prefixed to avoid name space clashes. The FLAGS-parameter to the former
curl_urlget() has been converted into a bunch of flags to use in separate
setopt calls. I'm still focusing on the easy-interface, as the curl tool is
now using that.
- Bjorn Reese has provided me with an asynchronous name resolver that I plan
to use in upcoming versions of curl to be able to gracefully timeout name
lookups.
Daniel (18 May 2000)
- Introduced LIBCURL_VERSION_NUM to the curl.h include file to better allow
source codes to be dependent on the lib version. This define is now set to
a dexadecimal number, with 8 bits each for major number, minor number and
patch number. In other words, version 1.2.3 would make it 0x010203. It also
makes a larger number a newer version.
Daniel (17 May 2000)
- Martin Kammerhofer correctly pointed out several flaws in the FTP range
option. I corrected them.
- Removed the win32 winsock init crap from the lib to the src/main.c file
in the application instead. They can't be in the lib, especially not for
multithreaded purposes.
Daniel (16 May 2000)
- Rewrote the src/main.c source to use the new easy-interface to libcurl 7.
There is still more work to do, but the first step is now taken.
<curl/easy.h> is the include file to use.
Daniel (14 May 2000)
- FTP URLs are now treated slightly different, more according to RFC 1738.
- FTP sessions are now performed differently, with CWD commands to change
directory instead of RETR/STOR/LIST with the full path. Discussions with
Rich Gray made me notice these problems.
- Janne Johansson discovered and corrected a buffer overflow in the
src/usrglob.c file.
- I had to add a lib/strequal.c file for doing case insensitive string
compares on all platforms.
Daniel (8 May 2000):
- Been working lots on the new lib.
- Together with Rich Gray, I've tried to adjust the configure script to work
better on the NCR MP-RAS Unix.
Daniel (2 May 2000):
- Albert Chin-A-Young pointed out that I had a few too many instructions in
configure.in that didn't do any good.
Daniel (24 April 2000):
- Added a new paragraph to the FAQ about what to do when configure can't
find OpenSSL even though it is installed. Supplied by Bob Allison
Daniel (12 April 2000):
- Started messing around big-time to convert the old library interface to a
better one...
Daniel (8 April 2000):
- Made the progress bar look better for file sizes between 9999 kilobytes
and 100 megabytes. They're now displayed XX.XM.
- I also noticed that ftp fetches through HTTP proxies didn't add the user
agent string. It does now.
- Habibie <habibie at MailandNews.com> supplied a pretty good way to build RPMs
on a Linux machine. It still a) requires me to be root to do it, b) leaves
the rpm packages laying at some odd place on my disk c) doesn't work to
build the ssl version of curl since I didn't install openssl from an rpm
package so now the rpm crap thinks I don't have openssl and refuses to build
a package that depends on ssl... Did I mention I don't get along with RPM?
- Once again I received a bug report about autoconf not setting -L prior to -l
on the command line when checking for libs. In this case it made the native
cc compiler on Solaris 7 to fail the OpenSSL check. This has previously been
reported to cause problems on HP-UX and is a known flaw in autoconf 2.13. It
is a pity there's no newer release around...
- Marco G. Salvagno supplied me with two fixes that
appearantly makes the OS/2 port work better with multiple URLs.
Daniel (2 April 2000):
- Another Location: fix. This time, when curl connected to a port and then
followed a location with an absolute URL to another port, it misbehaved.
Daniel (27 March 2000):
- H. Daphne Luong pointed out that curl was wrongly
messing up the proxy string when fetching a document through a http proxy,
which screwed up multiple fetches such as in location: followings.
- Marco G. Salvagno corrected my badly applied patch he
actually already told me about!
- H. Daphne Luong brought me a fix that now makes curl
ignore select() errors in the download if errno is EINTR, which turns out to
happen every now and then when using libcurl multi-threaded...
Daniel (22 March 2000):
- Wham Bang supplied a couple of win32 fixes. HAVE_UNAME
was accidentally #defined in config-win32.h, which it shouldn't have been.
The HAVE_UNISTD_H is not defined when compiling with the Makefile.vc6
makefile for MS VC++.
Daniel (21 March 2000):
- I removed the AC_PROG_INSTALL macro from configure.in, since it appears that
one of the AM_* macros searches for a BSD compatible install already. Janne
Johansson made me aware of this.
- Paul Harrington quickly pointed out to me that 6.5.1
crashes hard. I upload 6.5.2 now as quickly as possible! The problem was
- An anonymous post on sourceforge correctly pointed out a possible buffer
overflow in the curl_unescape() function for URL conversions. The main
problem with this bug is that the ftp download uses that function and this
single- byte overflow could lead to very odd bugs (as one reported by Janne
Johansson).
- Marco G. Salvagno supplied me with a series of patches
that now allows curl to get compiled on OS/2. It even includes a section in
the INSTALL file. Very nice job!
Daniel (17 March 2000):
- Wham Bang supplied a patch for the lib/Makefile.vc6
file. We still need some fixes for the config-win32.h since it appears that
VC++ and mingw32 have different opinions about (at least) unistd.h's
Daniel (15 March 2000):
- I modified the -D/--dump-header workings so that it doesn't write anything
to the file until it needs to. This way, you can actually use -b and -D
on the same file if you want repeated invokes to store and read the cookies
in that one single file.
- Poked around in lots of texts. Added the BUGS file for bug reporting stuff.
Added the classic HTTP POST question to the FAQ, removed some #ifdef WIN32
stuff from the sources (they're covered by the config-win32.h now).
- Pascal Gaudette fixed a missing ldap.c problem in the
Makefile.vc6 file. He also addressed a problem in src/config-win32.h.
Daniel (14 March 2000):
- Paul Harrington pointed out that the 'http_code' variable in the -w output
was never written. I fixed it now.
- Janne Johansson reported the complaints that OpenBSD does
when getdate.c #includes malloc.h. It claims stdlib.h should be included
instead. I added #ifdef HAVE_MALLOC_H code in getdate.y and two checks in
the configure.in for malloc.h and stdlib.h.
Version 6.5
- <curl at spam.wolvesbane.net> pointed out that the way curl sent cookies in a
single line wasn't enjoyed by IIS4.0 servers. In my view, that is not what
the standards say, but I added a white space between the name/value pairs to
perhaps make them work better.
- Added the perl check back in the configure.in again since the mkhelp.pl
script needs it!
- Made some beautifications in the curl man page.
Daniel (3 March 2000):
- Jörn helped me update the config-win32.h files with HAVE_SETVBUF and
HAVE_STRDUP.
Daniel (3 March 2000):
- Uploaded the 6.5pre2 package.
Daniel (2 March 2000):
- Removed the perl-programs from the distribution, they never made many people
happy and I'll still keep them available on the web.
- Added the -w and -N stuff to the man page. Documented the new progress meter
display in README.curl.
- Jörn Hartroth, Chris <cbayliss at csc.come> and Ulf
Möller from the openssl development team helped bringing me the details for
fixing an OpenSSL usage flaw. It became apparent when they released openssl
0.9.5 since that barfed on curl's bad behavior (not seeding a random number
thing).
- Yet another option: -N/--no-buffer disables buffering in the output stream.
Probably most useful for very slow transfers when you really want to get
every byte curl receives within some preferred time. Andrew <tmr at gci.net>
- Damien Adant mailed me his fixes for making curl compile on Ultrix.
Daniel (24 February 2000):
- Applied Jörn Hartroth's fixes for config-win32.h and lib/Makefile.w32.
I should also make a note here, if nothing else to myself, that when using
the %-syntax for variables in DOS command prompts, you must use two %-
letters for each one since that is an escape letter there! Maybe I should
use another letter instead!
- Added more variables to -w:
'http_code'
'time_namelookup'
'time_connect'
'time_pretransfer'
'url_effective'
- Made -w@filename read the syntax from a file and -w@- reads the syntax from
stdin in the good old "standard" curl way.
Daniel (22 February 2000):
- Released a 6.5pre1 version to get some test and user feedback.
Daniel (21 February 2000):
- I added the -w/--write-out flag and some variables to go with it. -w is a
single string, whatever you enter there will be written out when curl has
completed a successful request. There are some variable substitutions and
they are specified as '%{variable}' (without the quotes). Variables that
exist as of this moment are:
total_time - total transfer time in seconds (with 2 decimals)
size_download - total downloaded amount of bytes
size_upload - total uploaded amount of bytes
speed_download - the average speed of the entire download
speed_upload - the average speed of the entire upload
I will of course add more variables, but I need input on these and others.
- It struck me that the -# progress bar will be hard to just apply on the new
progress bar concept. I need some feedback on this before that'll get re-
introduced! :-/
Daniel (16 February 2000):
- Jörn Hartroth brought me some fixes for the progress meter and I continued
working on it. It seems to work for http download, http post, ftp download
and ftp upload. It should be a pretty good test it works generally good.
- Still need to add the -# progress bar into the new style progress interface.
- Gonna have a go at my new output option parameter next.
Daniel (15 February 2000):
- The progress meter stuff is slowly taking place. There's more left before it
is working ok and everything is tested, but we're reaching there. Slowly!
- Paul Marquis fixed the config file parsing of curl to
deal with any-length lines, removing the previous limit of 4K.
- Eetu Ojanen's suggestion of supporting the @-style for -b
is implemented. Now -b@<filename> works as well as the old style. -b@- also
- Reminder: -D should not write to the file until it needs to, in the same way
-o does. That would enable curl to use -b and -D on the same file...
- Ellis Pritchard made getdate.y work for MacOS X.
- Paul Harrington helped me out finding the crash in the
cookie parser. He also pointed out curl's habit of sending empty cookies to
Daniel (8 February 2000):
- Ron Zapp corrected a problem in src/urlglob.c that
prevented curl from getting compiled on sunos 4. The problem had to do
with the difference in sprintf() return code types.
- Transfer() should now be able to download and upload simultaneously. Let's
do some progress meter fixes later this week.
- Paul Harrington found another core dump in the cookie
parser. Curl doesn't properly recognize the 'version' keyword and I think
that is what caused this. I need to refresh some specs on cookies and see
what else curl lacks to improve this a bit more once and for all.
RFC 2109 clearly specifies how cookies should be dealt with when they are
compliant with that spec. I don't think many servers are though...
- Mark W. Eichin found that while curl is uploading a form
to a web site, it doesn't read incoming data why it'll hang after a while
since the socket "pipe" becomes full.
It took me two hours to rewrite Download() and Upload() into the new
single function Transfer(). It even seems to work! More testing is required
of course... I should get the header-sending together in a kind of queue
and let them get "uploaded" in Transfer() as well.
- Zhibiao Wu pointed out a curl bug in the location: area,
although I did not get a reproducible way to do this why I have to wait
support for the HTTP PUT operation, and as I think it is a valid suggestion
I'll work on it.
Daniel (25 January 2000):
- M Travis Obenhaus pointed out a manual mixup with -y and -Y that was
corrected.
- Jens Schleusener pointed out a problem to compile
curl on AIX 4.1.4 and gave me a solution. This problem was already fixed
by Jörn's recent #include modifications!
Daniel (19 January 2000):
- Oskar Liljeblad pointed out and corrected a problem
in the Location: following system that made curl following a location: to a
different protocol to fail.
At January 31st I re-considered this fix and the surrounding source code. I
could not really see that the patch did any difference, why I removed it
again for further research and debugging. (It disabled location: following
on server not running on default ports.)
made it possible to select progress bar.
- Jörn also fixed a few include problems.
- Based on suggestions from Björn Stenberg, I made the
progress deal better with larger files and added a "Time" field which shows
the time spent on the download so far.
- I'm now using the CVS repository on sourceforge.net, which also allows web
browsing. See http://curl.haxx.nu.
Daniel (10 January 2000):
- Renumbered some enums in curl/curl.h since tag number 35 was used twice!
- Added "postquote" support to the ftp section that enables post-ftp-transfer
quote commands.
- Now made the -Q/--quote parameter recognize '-' as a prefix, which means
that command will be issued AFTER a successful ftp transfer. This can of
course be used to delete or rename a file after it has been uploaded or
downloaded. Use your imagination! ;-)
- Since I do the main development on solaris 2.6 now, I had to download and
install GNU groff to generate the hugehelp.c file. The solaris nroff cores
on the man page! So, in order to make the solaris configure script find a
better result I made gnroff get checked prior to the regular nroff.
- Added all the curl exit codes to the man page.
- Jim Gallagher properly tracked down a bug in autoconf
2.13. The AC_CHECK_LIB() macro wrongfully uses the -l flag before the -L
flag to 'ld' which causes the HP-UX 10.20 flavour to fail on all libchecks
and therefore you can't make the configure script find the openssl libs!
doesn't support URL formatted file names when getting ftp. Now, there's a
problem with getting very weird file names off FTP servers. RFC 959 defines
that the file name syntax to use should be the same as in the native OS of
the server. Since we don't know the peer server system we currently just
translate the URL syntax into plain letters. It is still better and with
the solaris 2.6-supplied ftp server it works with spaces in the file names.
Daniel (27 December 1999):
- When curl parsed cookies straight off a remote site, it corrupted the input
data, which, if the downloaded headers were stored made very odd characters
in the saved data. Correctly identified and reported by Paul Harrington.
Daniel (13 December 1999):
- General cleanups in the library interface. There had been some bad kludges
added during times of stress and I did my best to clean them off. It was
both regarding the lib API as well as include file confusions.
Daniel (3 December 1999):
- A small --stderr bug was reported by Eetu Ojanen...
- who also brought the suggestion of extending the -X flag to ftp list as
well. So, now it is and the long option is now --request instead. It is
only for ftp list for now (and the former http stuff too of course).
- Patched curl to compile and build under BeOS. Doesn't work yet though!
- Corrected the Makefile.am files to allow putting object files in
different directories than the sources.
Version 6.3.1
Daniel (23 November 1999):
- I've had this major disk crash. My good old trust-worthy source disk died
along with the machine that hosted it. Thank goodness most of all the
things I've done are either backed up elsewhere or stored in this CVS
server!
- Michael S. Steuer pointed out a bug in the -F handling
that made curl hang if you posted an empty variable such as '-F name='. It
was one of those old bugs that never have worked properly...
- Jason Baietto pointed out a general flaw in the HTTP
download. Curl didn't complain if it was prematurely aborted before the
entire download was completed. It does now.
Daniel (19 November 1999):
- Chris Maltby very accurately criticized the lack of
return code checks on the fwrite() calls. I did a thorough check for all
occurrences and corrected this.
Daniel (17 November 1999):
- Paul Harrington pointed out that the -m/--max-time option
doesn't work for the slow system calls like gethostbyname()... I don't have
any good fix yet, just a slightly less bad one that makes curl exit hard
when the timeout is reached.
- Bjorn Reese helped me point out a possible problem that might be the reason
why Thomas Hurst experience problems in his Amiga version.
Daniel (12 November 1999):
- I found a crash in the new cookie file parser. It crashed when you gave
a plain http header file as input...
Version 6.3
Daniel (10 November 1999):
- I kind of found out that the HTTP time-conditional GETs (-z) aren't always
respected by the web server and the document is therefore sent in whole
again, even though it doesn't match the requested condition. After reading
section 13.3.4 of RFC 2616, I think I'm doing the right thing now when I do
my own check as well. If curl thinks the condition isn't met, the transfer
is aborted prematurely (after all the headers have been received).
- After comments from Robert Linden I also rewrote some parts of the man page
to better describe how the -F works.
- Michael Anti put up a new curl download mirror in
China: http://www.pshowing.com/curl/
- I added the list of download mirrors to the README file
- I did add more explanations to the man page
Daniel (8 November 1999):
- I made the -b/--cookie option capable of reading netscape formatted cookie
files as well as normal http-header files. It should be able to
transparently figure out what kind of file it got as input.
Daniel (29 October 1999):
- Another one of Sebastiaan van Erk's ideas (that has been requested before
but I seem to have forgotten who it was), is to add support for ranges in
FTP downloads. As usual, one request is just a request, when they're two
it is a demand. I've added simple support for X-Y style fetches. X has to
be the lower number, though you may omit one of the numbers. Use the -r/
--range switch (previously HTTP-only).
- Sebastiaan van Erk suggested that curl should be
able to show the file size of a specified file. I think this is a splendid
idea and the -I flag is now working for FTP. It displays the file size in
this manner:
Content-Length: XXXX
As it resembles normal headers, and leaves us the opportunity to add more
info in that display if we can come up with more in the future! It also
makes sense since if you access ftp through a HTTP proxy, you'd get the
file size the same way.
I changed the order of the QUOTE command executions. They're now executed
just after the login and before any other command. I made this to enable
quote commands to run before the -I stuff is done too.
- I found out that -D/--dump-header and -V/--version weren't documented in
the man page.
- Many HTTP/1.1 servers do not support ranges. Don't ask me why. I did add
some text about this in the man page for the range option. The thread in
the mailing list that started this was initiated by Michael Anti.
- I get reports about nroff crashes on solaris 2.6+ when displaying the curl
man page. Switch to gnroff instead, it is reported to work(!). Adam Barclay
- In a dialogue with Johannes G. Kristinsson we came
up with the idea to let -H/--header specified headers replace the
internally generated headers, if you happened to select to add a header
that curl normally uses by itself. The advantage with this is not entirely
obvious, but in Johannes' case it means that he can use another Host: than
the one curl would set.
Daniel (27 October 1999):
- Jongki Suwandi brought a nice patch for (yet another) crash when following
a location:. This time you had to follow a https:// server's redirect to
get the core.
Version 6.2
Daniel (21 October 1999):
- I think I managed to remove the suspicious (nil) that has been seen just
before the "Host:" in HTTP requests when -v was used.
- I found out that if you followed a location: when using a proxy, without
having specified http:// in the URL, the protocol part was added once again
when moving to the next URL! (The protocol part has to be added to the
URL when going through a proxy since it has no protocol-guessing system
such as curl has.)
- Benjamin Ritcey reported a core dump under solaris 2.6
with OpenSSL 0.9.4. It turned out this was due to a bad free() in main.c
that occurred after the download was done and completed.
- Benjamin found ftp downloads to show the first line of the download meter
to get written twice, and I removed that problem. It was introduced with
the multiple URL support.
- Dan Zitter correctly pointed out that curl 6.1 and earlier versions didn't
honor RFC 2616 chapter 4 section 2, "Message Headers": "...Field names are
case-insensitive..." HTTP header parsing assumed a certain casing. Dan
also provided me with a patch that corrected this, which I took the liberty
of editing slightly.
- Dan Zitter also provided a nice patch for config.guess to better recognize
the Mac OS X
- Dan also corrected a minor problem in the lib/Makefile that caused linking
to fail on OS X.
Daniel (19 October 1999):
- Len Marinaccio came up with some problems with curl. Since Windows has a
crippled shell, it can't redirect stderr and that causes trouble. I added
--stderr today which allows the user to redirect the stderr stream to a
file or stdout.

Daniel (18 October 1999):
- The configure script now understands the '--without-ssl' flag, which now
totally disable SSL/https support. Previously it wasn't possible to force
the configure script to leave SSL alone. The previous functionality has
been retained. Troy Engel helped test this new one.
Version 6.1
Daniel (17 October 1999):
- I ifdef'ed or commented all the zlib stuff in the sources and configure
script. It turned out we needed to mock more with zlib than I initially
thought, to make it capable of downloading compressed HTTP documents and
uncompress them on the fly. I didn't mean the zlib parts of curl to become
more than minor so this means I halt the zlib expedition for now and wait
until someone either writes the code or zlib gets updated and better
adjusted for this kind of usage. I won't get into details here, but a
short a summary is suitable:
- zlib can't automatically detect whether to use zlib or gzip
decompression methods.
- zlib is very neat for reading gzipped files from a file descriptor,
although not as nice for reading buffer-based data such as we would
want it.
- there are still some problems with the win32 version when reading from
a file descriptor if that is a socket
Daniel (14 October 1999):
- Moved the (external) include files for libcurl into a subdirectory named
curl and adjusted all #include lines to use <curl/XXXX> to maintain a
better name space and control of the headers. This has been requested.
Daniel (12 October 1999):
- I modified the 'maketgz' script to perform a 'make' too before a release
archive is put together in an attempt to make the time stamps better and
hopefully avoid the double configure-running that use to occur.
Daniel (11 October 1999):
- Applied Jörn's patches that fixes zlib for mingw32 compiles as well as
some other missing zlib #ifdef and more text on the multiple URL docs in
the man page.
Version 6.1beta
Daniel (6 October 1999):
- Douglas E. Wegscheid sent me a patch that made the exact same thing as I
just made: the -d switch is now capable of reading post data from a named
file or stdin. Use it similarly to the -F. To read the post data from a
given file:
curl -d @path/to/filename www.postsite.com
or let curl read it out from stdin:
curl -d @- www.postit.com
Jörn Hartroth (3 October 1999):
- Brought some more patches for multiple URL functionality. The MIME
separation ideas are almost scrapped now, and a custom separator is being
used instead. This is still compile-time "flagged".
Daniel
- Updated curl.1 with multiple URL info.
Daniel (30 September 1999):
- Felix von Leitner brought openssl-check fixes for configure.in to work
out-of-the-box when the openssl files are installed in the system default
dirs.
Daniel (28 September 1999)
- Added libz functionality. This should enable decompressing gzip, compress
or deflate encoding HTTP documents. It also makes curl send an accept that
it accepts that kind of encoding. Compressed contents usually shortens
download time. I *need* someone to tell me a site that uses compressed HTTP
documents so that I can test this out properly.
- As a result of the adding of zlib awareness, I changed the version string
a little. I plan to add openldap version reporting in there too.
Daniel (17 September 1999)
- Made the -F option allow stdin when specifying files. By using '-' instead
of file name, the data will be read from stdin.
Version 6.0
Daniel (13 September 1999)
- Added -X/--http-request <request> to enable any HTTP command to be sent.
Do not that your server has to support the exact string you enter. This
should possibly a string like DELETE or TRACE.
- Applied Douglas' mingw32-fixes for the makefiles.
Daniel (10 September 1999)
- Douglas E. Wegscheid pointed out a problem. Curl didn't check the FTP
servers return code properly after the --quote commands were issued. It
took anything non 200 as an error, when all 2XX codes should be accepted as
OK.
- Sending cookies to the same site in multiple lines like curl used to do
turned out to be bad and breaking the cookie specs. Curl now sends all
cookies on a single Cookie: line. Curl is not yet RFC 2109 compliant, but I
doubt that many servers do use that syntax (yet).
Daniel (8 September 1999)
- Jörn helped me make sure it still compiles nicely with mingw32 under win32.
Daniel (7 September 1999)
- FTP upload through proxy is now turned into a HTTP PUT. Requested by
- Added the ldap files to the .m32 makefile.
Daniel (3 September 1999)
- Made cookie matching work while using HTTP proxy.
- Passed his ldap:// patch. Note that this requires the openldap shared
library to be installed and that LD_LIBRARY_PATH points to the
directory where the lib will be found when curl is run with a
ldap:// URL.
- Made the Mingw32 makefiles into single files.
- Made file:// work for Win32. The same code is now used for unix as well for
performance reasons.
- Made a cool patch for configure.in to allow --with-ssl to specify the
root dir of the openssl installation, as in
./configure --with-ssl=/usr/ssl_here
- Corrected the 'reconf' script to work better with some shells.
- Fixed the Mingw32 makefiles in lib/ and corrected the file.c for win32
compiles.
Version 5.11
Daniel (25 August 1999)
- John Weismiller pointed out a bug in the header-line
realloc() system in download.c.
- I added lib/file.[ch] to offer a first, simple, file:// support. It
probably won't do much good on win32 system at this point, but I see it
as a start.
- Made the release archives get a Makefile in the root dir, which can be
used to start the compiling/building process easier. I haven't really
changed any INSTALL text yet, I wanted to get some feed-back on this
first.
Daniel (17 August 1999)
- Another Location: bug. Curl didn't do proper relative locations if the
original URL had cgi-parameters that contained a slash. Nusu's page
again.
- Corrected the NO_PROXY usage. It is a list of substrings that if one of
them matches the tail of the host name it should connect to, curl should
not use a proxy to connect there. Pointed out to me by Douglas
E. Wegscheid. I also changed the README text a little regarding this.
Daniel (16 August 1999)
- Fixed a memory bug with http-servers that sent Location: to a Location:
page. Nusu's page showed this too.
- Made cookies work a lot better. Setting the same cookie name several times
used to add more cookies instead of replacing the former one which it
should've. Nusu <nus at intergorj.ro> brought me an URL that made this
painfully visible...
Troy (15 August 1999)
- Brought new .spec files as well as a patch for configure.in that lets the
configure script find the openssl files better, even when the include
files are in /usr/include/openssl
Version 5.10
Daniel (13 August 1999)
- SSL_CTX_set_default_passwd_cb() has been modified in the 0.9.4 version of
OpenSSL. Now why couldn't they simply add a *new* function instead of
modifying the parameters of an already existing function? This way, we get
a compiler warning if compiling with 0.9.4 but not with earlier. So, I had
to come up with a #if construction that deals with this...
- Made curl output the SSL version number get displayed properly with 0.9.4.
Troy (12 August 1999)
- Added MingW32 (GCC-2.95) support under Win32. The INSTALL file was also
a bit rearranged.
Daniel (12 August 1999)
- I had to copy a good <arpa/telnet.h> include file into the curl source
tree to enable the silly win32 systems to compile. The distribution rights
allows us to do that as long as the file remains unmodified.
- I corrected a few minor things that made the compiler complain when
-Wall -pedantic was used.
- I'm moving the official curl web page to http://curl.haxx.nu. I think it
will make it easier to remember as it is a lot shorter and less cryptic.
The old one still works and shows the same info.
Daniel (11 August 1999)
- Albert Chin-A-Young mailed me another correction for NROFF in the
configure.in that is supposed to be better for IRIX users.
Daniel (10 August 1999)
- Albert Chin-A-Young helped me with some stupid Makefile things, as well as
some fiddling with the getdate.c stuff that he had problems with under
HP-UX v10. getdate.y will now be compiled into getdate.c if the appropriate
yacc or bison is found by the configure script. Since this is slightly new,
we need to test the output getdate.c with win32 systems to make sure it
still compiles there.
Daniel (5 August 1999)
- I've just setup a new mailing list with the intention to keep discussions
around libcurl development in it. I mainly expect it to be for thoughts and
brainstorming around a "next generation" library, rather than nitpicking
about the current implementation or details in the current libcurl.
To join our happy bunch of future-looking geeks, enter 'subscribe
<address>' in the body of a mail and send it to
libcurl-request@listserv.fts.frontec.se. Curl bug reports, the usual curl
talk and everything else should still be kept in this mailing list. I've
