Changes :
- Jeff Lawson fixed a few problems with connection re-use that remained when
you set CURLOPT_PROXY to "".
- Craig Davison found a terrible flaw and Cris Bailiff helped out in the
search. Getting HTTP data from servers when the headers are split up in
multiple reads, could cause junk data to get inserted among the saved
headers. This only concerns HTTP(S) headers.
- Vincent Penquerc'h gave us the good suggestion that when the ERRRORBUFFER
is set internally, the error text is sent to the debug function as well.
- Fixed the telnet code to timeout properly as the option tells it to. On
non-windows platforms.
- John Crow pointed out that libcurl-the-guide wasn't included in the release
tarball!
- Kevin Roth pointed out that make install didn't do right if build outside
the source tree (ca-bundle wise).
- FOLLOW_LOCATION bugfix for the multi interface
[trim], more see CHANGES.
- fmt on DESCR
- Regen PLIST
- Remove patch since it was applied
Changes since curl-7.9.5
(Lots of change, here is the recently changes, see CHANGE for more)
- Dirk Manske brought a fix that makes libcurl strip off white
spaces from the beginning of cookie contents.
- Had to patch include/curl/curl.h since MSVC doesn't set the
__STDC__ define. Moonesamy pointed out the problem, Bjorn Reese
the solution.
- Fixed the TIMER_CONNECT to be more accurate for FTP transfers.
Previously FTP transfers got the "connect done" time set after
the initial FTP commands and not directly after the TCP/IP connect
as it should.
- Jean-Philippe Barrette-LaPierre provided his patch that introduces
CURLOPT_DEBUGFUNCTION and CURLOPT_DEBUGDATA. They allow a program
to a set a callback to receive debug/information data. That
includes headers and data that is received and sent. CURLOPT_VERBOSE
still controls it.
By default, there is an internal debugfunction that will make
things look and work as before if not changed.
- Sebastien Willemijns found out that -x didn't use the default
port number as is documented. It does now.
- libcurl-errors.3 is a new man page attempting to document all
libcurl error codes
LTCONFIG_OVERRIDE changed to LIBTOOL_OVERRIDE.
GNU make no longer needed.
Install some documentation in ${PREFIX}/share/doc/curl, and examples of
libcurl usage in ${PREFIX}/share/examples/curl.
XXX A buildlink.mk would be nice to have...
Bump PKGREVISION for the PLIST additions.

Version 7.9.5
Daniel (7 March 2002)
- Added docs/KNOWN_BUGS to the release archive.
Daniel (6 March 2002)
- Kevin Roth corrected a flaw in the curl client globbing code that made it
mess up backslashes. This was most notable on windows (cygwin) machines when
using file://.
- Brad provided another fix for building outside the source-tree.
- Ralph Mitchell patched away a few compiler warnings in tests/server/sws.c
Daniel (5 March 2002)
- I noticed that the typedef in curl.h for the progress callback prototype was
wrong and thus applications that used it would not get the proper input
data. It used size_t where the implementation actually uses doubles!
I wish I could blame someone else, but this was my fault. Again.
Version 7.9.5-pre6
Daniel (4 March 2002)
- Cut off the changes done during 2001 from this changelog file and put them
in a separate file (CHANGES.2001), available from CVS of course.
- I removed the multi directory. The example sources were moved to the
docs/examples directory where they belong.
- Wrote 7 new man pages for the current functions in the new multi interface.
They're all still pretty basic, but we can use them as a start and add more
contents to them when we figure out what to write. The large amount of man
pages for libcurl now present made me decide to put them in a new separate
subdirectory in the docs directory. Named libcurl.
- Giuseppe Corbelli provided a template file for the EPM package manager, it
gets generated nicely by the configure script now.
Version 7.9.5-pre5
Daniel (1 March 2002)
- Moved the memanalyze.pl script into the tests/ dir and added it to the
release archives. It was previously only present in the CVS tree.
- Modified the February 17th Host: fix, as bug report #523718 pointed out that
it caused crashes!
- Nico Baggus added more error codes to the VMS stuff.
- Wesley Laxton brought the code that introduced the new CURLOPT_PREQUOTE
option. It is just another FTP quote option that allows the user to specify
a list of FTP commands to issue *just before* the transfer command (RETR or
STOR etc). It has turned up a few systems that really need this.
The curl command line tool can also take advantage of this by prefixing the
quote commands with a plus (+) in similar style that post transfer quote
commands are specified.
This is not yet documented. There is no test case for this yet.
Daniel (28 February 2002)
- Ralph Mitchell made some serious efforts and put a lot of sweat in setting
up scripts and things for me to be able to repeat his problems, and I
finally could. I found a problem with the header byte counter that wasn't
increased properly and thus we could return CURLE_GOT_NOTHING when we in
fact had received data.
Daniel (27 February 2002)
- I had to revert the non-space parsing cookie fix I posted to the mailing
list. Expire dates do have spaces and still need to get parsed properly!
Instead we just ignore trailing white space and it seems to work...
Daniel (26 February 2002)
- Made the cookie property 'Max-Age' work, just since we already tried to
support it, it is better to do it right. No one uses this anyway.
- The cookie parser could crash if a really weird (illegal) cookie line was
received. I also made it better discard really oddly formatted lines better.
Made the cookie jar store the second field from the left using the syntax
that Netscape and Mozilla probably like. Curl itself ignores it.
Added test case 31 for these cases.
Clay Loveless' email regarding some cookie issues started my cleanup.
- Kevin Roth pointed out that my automake fiddles broke the ability to build
outside the source-tree and I posted a patch to the mailing list that brings
this ability back.
Version 7.9.5-pre4
Daniel (25 February 2002)
- Fiddled with the automake files to make all source files in the lib
directory not have ../src in the include path, and the src sources shouldn't
have ../lib!
- All 79 test cases ran OK under Linux and Solaris using the new HTTP server
in the test suite. The new HTTP server was first donated by Georg Horn and
subsequently modified to work with the test suite. It is currently still not
portable enough to run on "all over" but this is a start and I can run all
curl tests on my machines. This is an important requirement for the upcoming
public release.
- Using -d and -I on the same command line now reports an error, as it implies
two different HTTP requests that can't be mixed.
- Jeffrey Pohlmeyer provided a patch that made the -w/--write-out option
support %{content_type} to get the content type of the recent download.
- Kevin Roth reported that pre2 and pre3 didn't compile properly on cygwin,
and this was because I used #ifdef HAVE_WINSOCK_H in lib/multi.h to figure
out if we could include winsock.h which turns out not to be a wise choice to
do on cygwin since it has the file but can't include it!
Daniel (22 February 2002)
- Added src/config-vms.h to the release archive.
- Fixed the connection timeout value again, the change from February 18 wasn't
complete.
Version 7.9.5-pre3
Daniel (21 February 2002)
- Kevin Roth and Andrés García both found out that lib/config.h.in was missing
in the pre-release archive and thus the configure script failed.
Version 7.9.5-pre2
Daniel (20 February 2002)
- Andrés García provided a solution to bug report #515228. the total time
counter was not set correctly when -I was used during some conditions (all
headers were read in one single read).
- Nico Baggus provided a huge patch with minor tweaks all over to make curl
compile nicely on VMS.
Daniel (19 February 2002)
- Rick Richardson found out that by replacing PF_UNSPEC with PF_INET in the
getaddrinfo() calls, he could speed up some name resolving calls with an
order of magnitudes on his Redhat Linux 7.2.
- Philip Gladstone found a second INADDR_NONE problem where we used long
intead of in_addr_t which caused 64bit problemos. We really shouldn't define
that on two different places.
Daniel (18 February 2002)
- Philip Gladstone found a problem in how HTTP requests were sent if the
request couldn't be sent all at once.
- Emil found and corrected a bad connection timeout comparison that made curl
use the longest of connect-timeout and timout as a timeout value, instead of
the shortest as it was supposed to!
- Aron Roberts provided updated information about LDAP URL syntax to go into
the manual as a replacement for the old references.
Daniel (17 February 2002)
- Philip Gladstone pointed out two missing include files that made curl core
dump on 64bit architectures. We need to pay more attention on these details.
It is *lethal* to for example forget the malloc() prototype, as 'int' is
32bit and malloc() must return a 64bit pointer on these platforms.
- Giaslas Georgios fixed a problem with Host: headers on repeated requests on
the same handle using a proxy.
Daniel (8 February 2002)
- Hanno L. Kranzhoff accurately found out that disabling the Expect: header
when doing multipart formposts didn't work very well. It disabled other
parts of the request header too, resulting in a broken header. When I fixed
this, I also noticed that the Content-Type wasn't possible to disable. It is
now, even though it probably is really stupid to try to do this (because of
the boundary string that is included in the internally generated header,
used as form part separator.)
Daniel (7 February 2002)
- I moved the config*.h files from the root directory to the lib/ directory.
- I've added the new test suite HTTP server to the CVS repository, It seems to
work pretty good now, but we must make it get used by the test scripts
properly and then we need to make sure that it compiles, builds and runs on
most operating systems.
Version 7.9.5-pre1
Daniel (6 February 2002)
- Miklos Nemeth provided updated windows makefiles and INSTALL docs.
- Mr Larry Fahnoe found a problem with formposts and I managed to track down
and patch this bug. This was actually two bugs, as the posted size was also
said to be two bytes too large.
- Brent Beardsley found out and brought a correction for the
CURLINFO_CONTENT_TYPE parser that was off one byte. This was my fault, I
accidentaly broke Giaslas Georgios' patch.
Daniel (5 February 2002)
- Kevin Roth found yet another SSL download problem.
Version 7.9.4
- no changes since pre-release
Version 7.9.4-pre2
Daniel (3 February 2002)
- Eric Melville provided a few spelling corrections in the curl man page.
Daniel (1 February 2002)
- Andreas Damm corrected the unconditional use of gmtime() in getdate, it now
uses gmtime_r() on all hosts that have it.
Daniel (31 January 2002)
- An anonymous bug report identified a problem in the DNS caching which made it
sometimes allocate one byte too little to store the cache entry in. This
happened when the port number started with 1!
- Albert Chin provided a patch that improves the gethostbyname_r() configure
check on HP-UX 11.00.
Version 7.9.4-pre1
Daniel (30 January 2002)
- Georg Horn found another way the SSL reading failed due to the non-blocking
state of the sockets! I fixed.
Daniel (29 January 2002)
- Multipart formposts now send the full request properly, including the CRLF.
They were previously treated as part of the post data.
- The upload byte counter bugged.
- T. Bharath pointed out that we seed SSL on every connect, which is a time-
consuming operation that should only be needed to do once. We patched
libcurl to now only seed on the first connect when unseeded. The seeded
status is global so it'll now only happen once during a program's life time.
If the random_file or egdsocket is set, the seed will be re-made though.
- Giaslas Georgios introduced CURLINFO_CONTENT_TYPE that lets
curl_easy_getinfo() read the content-type from the previous request.
Daniel (28 January 2002)
- Kjetil Jacobsen found a way to crash curl and after much debugging, it
turned out it was a IPv4-linux only problem introduced in 7.9.3 related to
name resolving.
- Andreas Damm posted a huge patch that made the curl_getdate() function fully
reentrant!
- Steve Marx pointed out that you couldn't mix CURLOPT_CUSTOMREQUEST with
CURLOPT_POSTFIELDS. You can now!
Daniel (25 January 2002)
- Krishnendu Majumdar pointed out that the header length counter was not reset
between multiple requests on the same handle.
- Pedro Neves rightfully questioned why curl always append \r\n to the data
that is sent in HTTP POST requests. Unfortunately, this broke the test suite
as the test HTTP server is lame enough not to deal with this... :-O
- Following Location: headers when the connection didn't close didn't work as
libcurl didn't properly stop reading. This problem was added in 7.9.3 due to
the restructured internals. 'Frank' posted a bug report about this.
Daniel (24 January 2002)
- Kevin Roth very quickly spotted that we wrongly installed the example
programs that were built in the multi directory, when 'make install' was
used. :-/
Version 7.9.3
Daniel (23 January 2002)
- Andrés García found a persistancy problem when doing HTTP HEAD, that made
curl "hang" until the connection was closed by the server. This problem has
been introduced in 7.9.3 due to internal rewrites, this was not present in
7.9.2.
Version 7.9.3-pre4
Daniel (19 January 2002)
- Antonio filed bug report #505514 and provided a fix! When doing multipart
formposts, libcurl would include an error text in the actual post if a
specified file wasn't found. This is not libcurl's job. Instead we add an
empty part.
Daniel (18 January 2002)
- Played around with stricter compiler warnings for gcc (when ./configure
--enable-debug is used) and changed some minor things to stop the warnings.
- Commented out the 'long long' and 'long double' checks in configure.in, as
we don't currently use them anyway and the code in lib/mprintf.c that use
them causes warnings.
- Saul Good and jonatan pointed out Mac OS X build problems with pre3 and how
to correct them. Two compiler warnings were removed as well.
- Andrés García fixed two minor mingw32 building problems.
Version 7.9.3-pre3
Daniel (17 January 2002)
- docs/libcurl-the-guide is a new tutorial for our libcurl programming
friends.
- Richard Archer brought back the ability to compile and build with OpenSSL
versions before 0.9.5.
[http://sourceforge.net/tracker/?func=detail&atid=100976&aid=504163&group_id=976]
- The DNS cache code didn't take the port number into account, which made it
work rather bad on IPv6-enabled hosts (especially when doing passive
FTP). Sterling fixed it.
Daniel (16 January 2002)
- Georg Horn could make a transfer time-out without error text. I found it and
corrected it.
- SSL writes didn't work, they return an uninitialized value that caused
havoc all over. Georg Horn experienced this.
- Kevin Roth patched the curl_version() function to use the proper OpenSSL
function for version information. This way, curl will report the version of
the SSL library actually running right now, not the one that had its headers
installed when libcurl was built. Mainly intersting when running with shared
OpenSSL libraries.
Version 7.9.3-pre2
Daniel (16 January 2002)
- Mofied the main transfer loop and related stuff to deal with non-blocking
sockets in the upload section. While doing this, I've now separated the
connection oriented buffers to have one for downloads and one for uploads
(as two can happen simultaneously). I also shrunk the buffers to 20K
each. As we have a scratch buffer twice the size of the upload buffer, we
arrived at 80K for buffers compared with the previous 150K.
- Added the --cc option to curl-config command as it enables so very cool
one-liners. Have a go a this one, building the simple.c example:
$ `curl-config --cc --cflags --libs` -o example simple.c
Daniel (14 January 2002)
- I made all socket reads (recv) handle EWOULDBLOCK. I hope nicely. Now we
only need to address all writes (send) too and then I'm ready for another
pre-release...
- Stoned Elipot patched the in_addr_t configure test to make it work better on
more platforms.
Daniel (9 January 2002)
- Cris Bailiff found out that filling up curl's SSL session cache caused a
crash!
- Posted the curl questionnaire on the web site. If you haven't posted your
opinions there yet, go there and do it now while it is still there:
http://curl.haxx.se/q/
- Georg Horn quickly found out that the SSL reading no longer worked as
supposed since the switch to non-blocking sockets. I've made a quick patch
(for reading only) but we should improve it even further.
Version 7.9.3-pre1
Daniel (7 January 2002)
- I made the 'bool' typedef use an "unsigned char". It makes it the same on
all platforms, no matter what the platform thinks the default format for
char is. This was noticed since we made a silly comparison involving such a
bool variable, and only one compiler/platform combination (on Debian Linux)
complained about it (that happened to have its char unsigned by default).
- Bug report #495290 identified a cookie parsing problem that was corrected.
When a Set-Cookie: line is received without a trailing semicolon, libcurl
didn't read the last "name=value" pair of the line, leading to confusions...
- Sterling committed his updated DNS cache code.
- I worked with Georg Horn and comments from Götz Babin-Ebell and switched
curl's socket operations completely over to non-blocking for the entire
operation (previously we used non-blocking only for the connection phase).
We had to do this to make the SSL connection phase timeout properly without
the use of signals. A little extra code to deal with this was added.
- T. Bharath pointed out a slightly obscure cookie engine flaw.
- Pete Su pointed out that libcurl didn't treat HTTP code 204 as it should.
204-replies never provides a response-body. This resulted in bad persistant
behavior when 204 was received.
Daniel (5 January 2002)
- SM updated the VC++ library Makefiles for the new source files.
Daniel (4 January 2002)
- I discovered that we wrongly used inet_ntoa() (instead of inet_ntoa_r() in
two places in the source code). One happened with VERBOSE set on connects,
and the other when VERBOSE was on and krb4 over nat was used... I honestly
don't think anyone has suffered from these mistakes.
- I replaced a lot of silly occurances of printf() to instead use the more
appropriate Curl_infof() or Curl_failf(). The krb4 and telnet code were
affected.
- Philip Gladstone found a few more problems with 64-bit archs (the 64-bit
sparc on solaris 8).
- After discussions on the libcurl list with Raoul Cridlig, I just made FTP
response lines get passed to the header callback if such a one is
registered. It'll make it possible for any application to get all the
responses an FTP server sends to libcurl.
Daniel (3 January 2002)
- Sterling Hughes brought a few buckets of code. Now, libcurl will
automatically cache DNS lookups and re-use the previous results first if any
such is available. It greatly improves speed when doing many repeated
operations to the same host.
- As the test case uses --include and then --head, I had to modify src/main.c
to deal with this situation slightly better than previously. When done, we
have 100% good tests again in the main branch.
Daniel (2 January 2002)
- Made test case 25 run again in the multi-dev branch. But it seems that the
changes done on dec-20 made test case 104 cease to work (in both branches).
- Philip Gladstone pointed out a few portability problems in the source code
that didn't compile on 64-bit sparcs using Sun's native
Trivial patch on configure which fixes compilation on NetBSD/!i386 added.
Fixed in 7.9.2
- compiles and builds on the good old Mac OS (in addition to Mac OS X)
- bugfixed persistant connections over proxy with multiple protocols
- --disable-epsv is a new option to the curl command line tool
- bugfixed verbose ftp output on Tru64 unix
- added CURLOPT_FTP_USE_EPSV
- passive ftp download works with IPv6
- always return proper error code on failed connects
- bugfixed FTP response reader
- bugfixed verbose telnet
- added CURLINFO_STARTTRANSFER_TIME
- bugfixed conditional HTTP fetches based on time

- "current speed" progress meter bugfix
- improved the name resolver configure check
- libcurl now restores signal handlers and timeouts properly
- improved SSL over HTTP-proxy when using weird proxies(!)
- added the -1/--TLSv1 option
- bugfixed LDAP transfers
Fixed in 7.9.1

libcurl now treats an already completed resumed download as a
successful operation, and not as an error like before
https and ftps test cases added to the test suite (depend on stunnel)
better white space awareness when parsing HTTP headers
curl -I now plays ball even if the ftp server doesn't grok SIZE
corrected resumed transfers on re-used persistent connections
FTP PORT works again when libcurl is IPv6-enabled
corrected path usage when doing multiple FTP transfers
several Location: header related bugs corrected
Version 7.7.1
Daniel (3 April 2001)
- Puneet Pawaia pointed out two serious problems. Libcurl would attempt to
read bad memory during situations when an (ftp) connection attempt failed.
Also, the lib/Makefile.vc6 was corrected.
- More investigations in the Location: following code made me realize that
it was not clean enough to work transparantly with persistant and non-
persistant connections. I think I've fixed it now.
Daniel (29 March 2001)
- Georg Horn mailed me some corrections for the Curl::easy perl interface.
- Experimental ftps:// support added. It is basically FTP over SSL for the
control connection. It still makes all data transfers going over unencrypted
connections. Rainer Weikusat's ftpd-ssl server hack supports this and I used
that to verify the functionality.
Daniel (27 March 2001)
- Guenole Bescon discovered that if you set a CURLOPT_TIMEOUT and then tried
to get a file from a site and it fails, the SIGALRM would still be sent
after the timeout-time, quite inexpectedly!
- I added an ftp transfer example to docs/examples/ and I also wrote a tiny
example makefile that can be used as a start when building one of the
examples.
Version 7.7.1-beta1
Daniel (26 March 2001)
- Mohamed Lrhazi reported problems with 7.6.1 and persistant HTTP/1.0
connections (when the server replied a Connection: Keep-Alive) and this
problem was not properly dealt with in 7.7 either. A patch was posted to the
curl-and-php mailing list.
Daniel (24 March 2001)
- Colin Watson reported about a problem and brought a patch that corrected it,
which was about the man page and lines starting with a single quote (') in a
way that gnroff doesn't like.
Daniel (23 March 2001)
- Peter Bray reported correctly that the root makefile used make instead of
$(MAKE) for the test target.
- Corrected the Curl::easy perl interface to use curl_easy_setopt() and not
curl_setopt() which was removed in 7.7!
- SM provided updates on three documents (MANUAL, INSTALL and FAQ).
- When following a Location:, libcurl would sometimes write to the URL string
in a way it shouldn't. As the pointer is passed-in to libcurl from an
application, we can't be allowed to write to it. The particular bug report
from 'nk' that brought this up was because he had a read-only URL that then
caused a libcurl crash!
- No longer reads HEAD responses longer than to the last header. Previously,
curl would read the full reply if the connection was a "close" one.
- libcurl did re-use connections way too much. Doing "curl
http://www.{microsoft,ibm}.com" would make it re-use the connection which
made the second request return very odd results.
Daniel (22 March 2001)
- Edin Kadribasic made me aware that curl should not re-send POST requests
when following 302-redirects. I made 302 work like 303 which means curl uses
GET in the following request(s).
- libcurl now reset the "followed-location" counter on each invoke of
curl_easy_perform() as it otherwise would sum up all redirects on the same
connection and thus could reach the maxredirs counter wrongly.
- Jim Drash suggested curl_escape() should not re-encode what already looks
like an encoded sequence and I think that's a fair suggestion.
Version 7.7
Daniel (22 March 2001)
- The configure script now fails with an error message if gethostbyname_r() is
detected but it couldn't figure out how to invoke it (what amount of
arguments it is supposed to get). Reports from Andrés García made me aware
of this need.
- Talking with Jim Drash made me finally put the curl_escape and curl_unescape
functions in the curl.h include file and write man pages for them. The
escape function was modified to use the same interface as the unescape one
had.
- No bug reports at all on the latest betas. Release time coming up.
Version 7.7-beta5
Daniel (19 March 2001)
- Georg Ottinger reported problems with using -C together with -L in the sense
that the -C info got lost when it was redirected. I could not repeat this
problem on the 7.7 branch why I leave this for the moment. Test case 39 was
added to do exactly this, and it seems to do right.
- Christian Robottom Reis reported how his 7.7 beta didn't successfully do
form posts as elegantly as 7.6.1 did. Indeed, this was a flaw in the header
engine, as HTTP 1.1 has introduced a new 100 "transient" return code for PUT
and POST operations that I need to add support for. Section 8.2.3 in RFC2616
has all the details. Seems to work now!
Daniel (16 March 2001)
- After having experienced another machine break-down, we're back.
- Georg Horn's perl interface Curl::easy is now included in the curl release
archive. The perl/ directory is now present. Please help me with docs,
examples and updates you think fit.
- Made a new php/ directory in the release archive and moved the PHP examples
into a subdirectory in there. Not much PHP info yet, but I plan to. Please
help me here as well!
- Made libcurl return error if a transfer is aborted in the middle of a
"chunk". It actually enables libcurl to discover premature transfer aborts
even if the Content-Length: size is unknown.
Daniel (15 March 2001)
- Added --connect-timeout to curl, which sets the new CURLOPT_CONNECTTIMEOUT
option in libcurl. It limits the time curl is allowed to spend in the
connection phase. This differs from -m/--max-time that limits the entire
file transfer operation. Requested by Larry Fahnoe and others.
I also updated the curl.1 and curl_easy_setopt.3 man pages and removed the
item from the TODO.
Version 7.7-beta4
Daniel (14 March 2001)
- Made curl grok IPv6 with HTTP proxies and got everything to compile nicely
again when ENABLE_IPV6 is set.
I need to remake things in the test suite. I can't test the FTP parts with
curl built for IPv6 as it uses a different set of FTP commands then!
- I fell onto a bug report on php.net (posted by Lars Torben Wilson) that was
a report meant for our project. Anyway, it said the .netrc parsing didn't
work as supposed, and as I agreed with Lars, I made the netrc parser use
getpwuid() to figure out the home directory of the effective user and try
that netrc. It still uses the environment variable HOME for those that don't
have that function or if the user doesn't return valid pwd info.
- Edin Kadribaic posted a bug report where he got a crash when a fetch with
user+password in the URL followed a Location: to a second URL (absolute,
without name+password). This bug has been around for a long while and
crashes due to a read at address zero. Fixed now. Wrote test case 38, that
tests this.
- Modified the test suite's httpserver slightly to append all client request
data to its log file so that the test script now better can verify a range
of requests and not only the last one, as it did previously.
- Updated the curl man page with --random-file and --egd-file details.
Version 7.7-beta3
Daniel (14 March 2001)
- Björn Stenberg provided similar fixes as Jörn did and some additional patches
for non-SSL compiles.
- I increased the interface number for libcurl as I've removed the low level
functions from the interface. I also took this opportunity to rename the
Curl_strequal function to curl_strequal and Curl_strnequal to
curl_strnequal, as they're public libcurl functions (even if they're still
undocumented).
This will make older programs not capable of using the new libcurl with
just a drop-in replacement.
- Jörn Hartroth updated stuff for win32 compiles:
o config-win32.h was fixed for socklen_t
o lib/ssluse.c had a bad #endif placement
o lib/file.c was made to compile on win32 again
o lib/Makefile.m32 was updated with the new files
o lib/libcurl.def matches the current interface state
Daniel (13 March 2001)
- It only took an hour or so before Jörn Hartroth found a problem in the
chunked transfer-encoding. Given his fine example-site, I could easily spot
the problem and when I re-read the spec (the part I have pasted in the top
of the http_chunks.h file), I realized I had made my state-machine slightly
wrong and didn't expect/handle the trailing CRLF that comes after the data
in each chunk (and those extra two bytes sure feel wasted).
Had to modify test case 34 to match this as well.
Version 7.7-beta2
Daniel (13 March 2001)
- Added the policy stuff to the curl_easy_setopt man page for the two supported
policies.
- Implemented some support for the CURLOPT_CLOSEPOLICY option. The policies
CURLCLOSEPOLICY_LEAST_RECENTLY_USED and CURLCLOSEPOLICY_OLDEST are now
supported, and the "least recently used" is used as default if no policy
is chosen.
Daniel (12 March 2001)
- Added CURLOPT_RANDOM_FILE and CURLOPT_EGDSOCKET to libcurl for seeding the
SSL random engine. The random seeding support was also brought to the curl
client with the new options --random-file <file> and --egd-file <file>. I
need some people to really test this to know they work as supposed. Remember
that libcurl now informs (if verbose is on) if the random seed is considered
weak (HTTPS connections).
- Made the chunked transfer-encoding engine detected bad formatted data length
and return error if so (we can't possibly extract sensible data if this is
the case). Added a test case that detects this. Number 36. Now there are 60
test cases.
- Added 5 new libcurl options to curl/curl.h that can be used to control the
persistant connection support in libcurl. They're also documented (fairly
thoroughly) in the curl_easy_setopt.3 man page. Three of them are now
implemented, although not really tested at this point... Anyway, the new
implemented options are named CURLOPT_MAXCONNECTS, CURLOPT_FRESH_CONNECT,
CURLOPT_FORBID_REUSE. The ones still left to write code for are:
CURLOPT_CLOSEPOLICY and its related option CURLOPT_CLOSEFUNCTION.
- Made curl (the actual command line tool) use the new libcurl 7.7 persistant
connection support by re-using the same curl handle for every specified file
transfer and after some more test case tweaking we have 100% test case OK.
I made some test cases return HTTP/1.0 now to make sure that works as well.
- Had to add 'Connection: close' to the headers of a bunch of test cases so
that curl behaves "old-style" since the test http server doesn't do multiple
connections... Now I get 100% test case OK.
- The curl.haxx.se site, the main curl mailing list and my personal email are
all dead today due to power blackout in the area where the main servers are
located. Horrible.
- I've made persistance work over a squid HTTP proxy. I find it disturbing
that it uses headers that aren't present in any HTTP standard though
(Proxy-Connection:) and that makes me feel that I'm now on the edge of what
the standard actually defines. I need to get this code excercised on a lot
of different HTTP proxies before I feel safe.
Now I'm facing the problem with my test suite servers (both FTP and HTTP)
not supporting persistant connections and libcurl is doing them now. I have
to fix the test servers to get all the test cases do OK.
Daniel (8 March 2001)
- Guenole Bescon reported that libcurl did output errors to stderr even if
MUTE and NOPROGRESS was set. It turned out to be a bug and happens if
there's an error and no ERRORBUFFER is set. This is now corrected.
Version 7.7-beta1
Daniel (8 March 2001)
- "Transfer-Encoding: chunked" is no longer any trouble for libcurl. I've
added two source files and I've run some test downloads that look fine.
- HTTP HEAD works too, even on 1.1 servers.
Daniel (5 March 2001)
- The current 57 test cases now pass OK. It would suggest that libcurl works
using the old-style with one connection per handle. The test suite doesn't
handle multiple connections yet so there are no test cases for this.
- I patched the telnet.c heavily to not use any global variables anymore. It
should make it a lot nicer library-wise.
- The file:// support was modified slightly to use the internal connect-first-
then-do approach.
Daniel (4 March 2001)
- More bugs erased.
Version 7.7-alpha2
Daniel (4 March 2001)
- Now, there's even a basic check that a re-used connection is still alive
before it is assumed so. A few first tests have proven that libcurl will
then re-connect instead of re-use the dead connection!
Daniel (2 March 2001)
- Now they work intermixed as well. Major coolness!
- More fiddling around, my 'tiny' client I have for testing purposes now has
proved to download both FTP and HTTP with persistant connections. They do
not work intermixed yet though.
Daniel (1 March 2001)
- Wilfredo Sanchez pointed out a minor spelling mistake in a man page and that
curl_slist_append() should take a const char * as second argument. It does
now.
Daniel (22 February 2001)
- The persistant connections start to look good for HTTP. On a subsequent
request, it seems that libcurl now can pick an already existing connection
if a suitable one exists, or it opens a new one.
- Douglas R. Horner mailed me corrections to the curl_formparse() man page
that I applied.
Daniel (20 February 2001)
- Added the docs/examples/win32sockets.c file for our windows friends.
- Linus Nielsen Feltzing provided brand new TELNET functionality and
improvements:
* Negotiation is now passive. Curl does not negotiate until the peer does.
* Possibility to set negotiation options on the command line, currently only
XDISPLOC, TTYPE and NEW_ENVIRON (called NEW_ENV).
* Now sends the USER environment variable if the -u switch is used.
* Use -t to set telnet options (Linus even updated the man page, awesome!)
- Haven't done this big changes to curl for a while. Moved around a lot of
struct fields and stuff to make multiple connections get connection specific
data in separate structs so that they can co-exist in a nice way. See the
mailing lists for discussions around how this is gonna be implemented. Docs
and more will follow.
Studied the HTTP RFC to find out better how persistant connections should
work. Seems cool enough.
Daniel (19 February 2001)
- Bob Schader brought me two files that help set up a MS VC++ libcurl project
easier. He also provided me with an up-to-date libcurl.def file.
- I moved a bunch of prototypes from the public <curl/curl.h> file to the
library private urldata.h. This is because of the upcoming changes. The
low level interface is no longer being planned to become reality.
Daniel (15 February 2001)
- CURLOPT_POST is not required anymore. Just setting the POST string with
CURLOPT_POSTFIELDS will switch on the HTTP POST. Most other things in
libcurl already works this way, i.e they require only the parameter to
switch on a feature so I think this works well with the rest. Setting a NULL
string switches off the POST again.
- Excellent suggestions from Rich Gray, Rick Jones, Johan Nilsson and Bjorn
Reese helped me define a way how to incorporate persistant connections into
libcurl in a very smooth way. If done right, no change may have to be made
to older programs and they will just start using persistant connections when
applicable!
Daniel (13 February 2001)
- Changed the word 'timeouted' to 'timed out' in two different error messages.
Suggested by Larry Fahnoe.
Version 7.6.1
Daniel (9 February 2001)
- Frank Reid and Cain Hopwood provided information and research around a HTTPS
PUT/upload problem we seem to have. No solution found yet.
Daniel (8 February 2001)
- An interesting discussion is how to specify an empty password without having
curl ask for it interactively? The current implmentation takes an empty
password as a request for a password prompt. However, I still want to
support a blank user field. Thus, today if you enter "-u :" (without user
and password) curl will prompt for the password. Tricky. How would you
specify you want the prompt otherwise?
- Made the netrc parse result possible to use for other protocols than FTP and
HTTP (such as the upcoming TELNET fixes).
- The previously mentioned "MSVC++ problems" turned out to be a non-issue.
- Added a HTTP file upload code example in the docs/examples/ section on
request.
- Adjusted the FTP response fix slightly.
Version 7.6.1-pre3
Daniel (7 February 2001)
- SM found a flaw in the response reading function for FTP that could make
libcurl not get out of the loop properly when it should, if libcurl got -1
returned when reading the socket.
- I found a similar mistake in http.c when using a proxy and reading the
results from the proxy connection.
Daniel (6 February 2001)
- A friendly person named "SM" (nntp at iname.com) pointed out that the VC
makefile in src/ needed the libpath set for the debug build to work.
- Daniel Gehriger stepped in to assist with the VC++ stuff Robert Weaver
brought up yesterday.
Daniel (5 February 2001)
- Jun-ichiro itojun Hagino brought a big patch that brings IPv6-awareness to
a bunch of different areas within libcurl.
- Robert Weaver told me about the problems the MS VC++ 6.0 compiler has with
the 'static' keyword on a number of libcurl functions. I might need to add a
patch that redefines static when libcurl is compiled with that compiler.
How do I know when VC++ compiles, anyone?
Daniel (4 February 2001)
- curl_getinfo() was extended with two new options:
CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD. They
return the full assumed content length of the transfer in the given
direction. The CURLINFO_CONTENT_LENGTH_DOWNLOAD will be the Content-Length:
size of a HTTP download. Added descriptions to the man page as well. This
was done after discussions with Bob Schader.
Daniel (3 February 2001)
- Ingo Ralf Blum provided another fix that makes curl build under the more
recent cygwin installations. It seems they've changed the preset defines to
not include WIN32 anymore.
Version 7.6.1-pre2
Daniel (31 January 2001)
- Curl_read() and curl_read() now return a ssize_t for the size, as it had to
be able to return -1. The telnet support crashed due to this and there was a
possibility to weird behaviour all over. Linus Nielsen Feltzing helped me
find this.
- Added a configure.in check for a working getaddrinfo() if IPv6 is requested.
I also made the configure script feature --enable-debug which sets a couple
of compiler options when used. It assumes gcc.
Daniel (30 January 2001)
- I finally took a stab at the long-term FIXME item I've had on myself, and
now libcurl will properly work when doing a HTTP range-request that follows
a Location:. Previously that would make libcurl fail saying that the server
doesn't seem to support range requests.
Daniel (29 January 2001)
- I added a test case for the HTTP PUT resume thing (test case 33).
Version 7.6.1-pre1
Daniel (29 January 2001)
- Yet another Content-Range change. Ok now? Bob Schader checks from his end
and it works for him.
Daniel (27 January 2001)
- So the HTTP PUT resume fix wasn't good. There should appearantly be a
Content-Range header when resuming a PUT.
- I noticed I broke the download-check that verifies that a resumed HTTP
download is actually resumed. It got broke because my new 'httpreq' field
in the main curl struct. I should get slapped. I added a test case for
this now, so I won't be able to ruin this again without noticing.
- Added a test case for content-length verifying when downloading HTTP.
- Made the progress meter title say if the transfer is being transfered. It
makes the output slightly better for resumes.
- When dealing with Location: and HTTP return codes, libcurl will not attempt
to follow the spirit of RFC2616 better. It means that when POSTing to a
URL that is being following to a second place, the standard will judge on
what to do. All HTTP codes except 303 and 305 will cause curl to make a
second POST operation. 303 will make a GET and 305 is not yet supported.
I also wrote two test cases for this POST/GET/Location stuff.
