History of Changes
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.
- 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.
- 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 compiler...
Daniel (20 December 2001)
- Björn Stenberg caught an unpleasent (but hard-to-find) bug that could cause
libcurl to hang on transfers over proxy, when the proxy was specified with
an environment variable!
- Added code to make ftp operations treat the NO_BODY and HEADERS options
better:
NO_BODY set TRUE and HEADERS set TRUE:
Return a set of headers with file info
NO_BODY set FALSE
Transfer data as usual, HEADERS is ignored
NO_BODY set TRUE and HEADERS set FALSE
Don't transfer any data, don't return any headers. Just perform the set
of FTP commands.
Daniel (17 December 2001)
- Götz Babin-Ebell dove into the dark dungeons of the OpenSSL ENGINE stuff and
made libcurl support it! This allows libcurl to do SSL connections with the
private key stored in external hardware.
To make this good, he had to add a bunch of new library options that'll be
useful to others as well:
CURLOPT_SSLCERTTYPE set SSL cert type (PEM/DER)
CURLOPT_SSLKEY set SSL private key (file)
CURLOPT_SSLKEYTYPE: set SSL key type (PEM/DER/ENG)
CURLOPT_SSLKEYPASSWD: set the passphrase for your private key
(CURLOPT_SSLCERTPASSWD is an alias)
CURLOPT_SSLENGINE: set the name of the crypto engine
(returns CURLE_SSL_ENGINE_NOTFOUND on error)
CURLOPT_SSLENGINE_DEFAULT: set the default engine
Loading full blame...
