History of Changes
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

- 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
There are two new failure codes:
CURLE_SSL_ENGINE_NOTFOUND
CURLE_SSL_ENGINE_SETFAILED
Daniel (14 December 2001)
- We have "branched" the source-tree at a few places. Checkout the CVS sources
with the 'multi-dev' label to get the latest multi interface development
tree. The idea is to only branch affected files and to restrict the branch
to the v8 multi interface development only.
*NOTE* that if we get bug reports and patches etc, we might need to apply
them in both branches!
The multi-dev branch is what we are gonna use as main branch in the future
if it turns out successful. Thus, we must maintain both now in case we need
them. The current main branch will be used if we want to release a 7.9.3 or
perhaps a 7.10 release before version 8. Which is very likely.
- Marcus Webster provided code for the new CURLFORM_CONTENTHEADER option for
curl_formadd(), that lets an application add a set of headers for that
particular part in a multipart/form-post. He also provided a section to the
man page that describes the new option.
Daniel (11 December 2001)
- Ben Greear made me aware of the fact that the Curl_failf() usage internally
was a bit sloppy with adding newlines or not to the error messages. Let's
once and for all say that they do not belong there!
- When uploading files with -T to give a local file name, and you end the URL
with a slash to have the local file name used remote too, we now no longer
use the local directory as well. Only the file part of the -T file name
will be appended to the right of the slash in the URL.
Daniel (7 December 2001)
- Michal Bonino pointed out that Digital Unix doesn't have gmtime_r so the
link failed. Added a configure check and corrected source code.
Version 7.9.2
Daniel (5 December 2001)
- Jon Travis found out that if you used libcurl and CURLOPT_UPLOAD and then
on the same handle used CURLOPT_HTTPGET it would still attempt to upload.
His suggested fix was perfect.
Daniel (4 December 2001)
- Incorporated more macos fixes and added four specific files in a new
subdirectory below src.
Daniel (3 December 2001)
- Eric Lavigne reported two problems:
First one in the curl_strnequal() function. I think this problem is rather
macos 9 specific, as most platform provides a function to use instead of the
one provided by libcurl.
A second, more important, was in the way we take care of FTP responses. The
Loading full blame...
