Daniel (12 May 2001)
- Jukka Pihl suggested that if (lib)curl is told to verify the peer's
certificate and the peer can't be verified, it should fail and return a
proper error code. I added a brand new error code named
CURLE_SSL_PEER_CERTIFICATE for this purpose.
Daniel (11 May 2001)
- As was discussed with Frederic Lepied a while ago, I now made libcurl not
return error even though no data was transfered on upload/download resume
when the no transfer is needed. The CURLE_ALREADY_COMPLETE error was removed
from the header file to make any implemenator that uses that to be aware of
the fact that it can't be returned anymore!
- Improved general header-parsing to better allow white spaces and more.
- Rodney Simmons proved the fix I did yesterday was bad and I had to post
another one.
- Ingo Wilken patched away two redirect problems more!
Daniel (10 May 2001)
- Cris Bailiff correctly noted that the space-after-header problem with
Location: is present on several other places in the libcurl sources.
- Ingo Wilken patched away a problem libcurl had when following Location:
headers with an extra space after the colon.
- Rodney Simmons found out that multiple FTP transfers did not treat relative
directories correctly.
Daniel (9 May 2001)
- Getting an FTP file with CURLOPT_NOBODY set (or -I from the command line),
makes curl use the non-standard ftp command "SIZE". If it failed, libcurl
returned error. Starting now, it just don't output the file size instead.
Anonymous bug report.
Daniel (7 May 2001)
- Corrected two minor compiler warnings due to the FILE * to void * conversion
that I missed at two places. Jörn Hartroth brought me patches. Sander Gates
filed a bug report on this.
Version 7.7.3
Daniel (4 May 2001)
- All callback functions now take 'void *' instead of 'FILE *'. This is made
this way to make it more obvious to people that anything can be passed to
them (by using the apropriate option). After discussions with Sterling
Hughes.
Daniel (3 May 2001)
- Cris Bailiff fixed a chunked transfer encoding problem with persistent
connection that made libcurl fail if the persistent connection used mixed
chunked and non-chunked transfers.
- Cris Bailiff fixed a bad treatment of 304-replies, as they would not be
treated as content-length 0 replies but would cause a "hang" until the
server timed-out and closed the connection.
- Brad Burdick found a minor problem in the docs/examples/Makefile.am

Daniel (27 April 2001)
- Updated the INTERALS document again. It was lagging a bit. I think I made it
more easy to follow now as well.
- Brad Burdick found a problem with persistent connections when curl received
a "Content-Length: 0" header.
- Giuseppe D'Ambrosio was first out to report that TELNET doesn't work in curl
compiled/built on win32. It seems to work for unixes though!
- Dave Hamilton reported weird problems with CURL/PHP that I really can't
explain at the moment. I'm hoping on some help from the PHP crew.
Daniel (26 April 2001)
- I rewrote the FTP command response function. I had to do it to make ftps
work, as the OpenSSL read()-function didn't work the same way the normal
unix read() does, but it was also a huge performance boost. Previously the
function read one byte at a time, now it reads very large chunks, and it
makes a notable speed difference.
Daniel (25 April 2001)
- Connection re-use when not using a proxy didn't work properly for
non-default port numbers.
Daniel (24 April 2001)
- I've noticed that FTPS doesn't work. We attempt to use ssl even for the
data transfer, which causes the transfer to 'hang'... We need to fix this.
- Improved the test suite to use 'stunnel' to do HTTPS and FTPS testing on
the alredy written perl servers easily.
Daniel (23 April 2001)
- The OpenSSL version string recently modified didn't zero terminate one
of the generated strings properly, which could lead to a crash or simply
weird version string output!
Version 7.7.2
Daniel (22 April 2001)
- Rosimildo da Silva updated the Makefiles for Borland/Windows.
- Eric Rautman pointed out a problem with persistent connections that would
lead to broken Host: headers in the second HTTP request.
Daniel (20 April 2001)
- Added man pages for the curl_strequal() and curl_mprintf() families. Wrote
a 'libcurl overview' man page.
- Spell-fixed some documents.
- S. Moonesamy corrected mistakes in the man page.
- Cris Bailiff fixed the curl_slists options in the perl interface, present
separately in the Curl::easy 1.1.4 package.
Daniel (19 April 2001)
- Linus Nielsen Feltzing removed the decimals from the size variables in the
--write-out output. We hardly ever get fraction of bytes! :-)
Version 7.7.2-pre1
Daniel (19 April 2001)
- Albert Chin provided a configure patch for the AC_SYS_LARGEFILE macro.
Daniel (18 April 2001)
- Input from Michael Mealling made me add --feature to curl-config. It
displays a list of features that have been built-in in the current
libcurl. The currently available features that can be listed are: SSL, KRB4
and IPv6.
- I committed Cris and Georg's perl interface work. They've got callbacks
working and options that receives those slist pointers.
- Puneet Pawaia detected a problem with resumed downloads that use persistent
connections and I made a rather large writeup to correct this. It is
important that all session-data is stored in the connectdata struct and not
in the main struct as this previously did.
Daniel (17 April 2001)
- Frederic Lepied fixed a ftp resumed download problem and introduced a new
error code that lets applications be able to detect when a resumed download
actually didn't download anything since the whole file is already present.
Should this return OK instead?
- I added 'curl-config.in' to the root dir and configure script. Now, a
curl-config script is made when curl is built. The script can be used to
figure out compile time options used when libcurl was built, which in turn
should be options YOU should use to build applications that use libcurl.
This *-config style is not a new idea, but something that has been used
successfully in other (library based) projects.
- Phil Karn pointed out that libcurl wrongly did not always use GMT time zone
for the If-Modified-Since style headers.
- Georg Schwarz pointed out an extra needed #include file needed in src/main.c
for curl to build on Ultrix.
Daniel (11 April 2001)
- Cris Bailiff pointed out two problems that I corrected. First, libcurl's use
of the environment variable HTTP_PROXY in uppercase may become a security
hazard when people use libcurl in a server/cgi situation where the server
sets the HTTP_*-variables according to incoming headers in the HTTP
request. Thus, a "Proxy:"-header would set that environment variable!
Then, invoking curl_easy_perform() without having an URL set caused a crash.
- S. Moonesamy brought a patch that make curl use non-blocking connects on
windows when connection timeout is set, as it allows windows users to set
that timeout!
- Hirotaka Matsuyuki wrote a Ruby interface to libcurl!
- Cris Bailiff, Forrest Cahoon and Georg Horn work on the Perl interface.
- I've written a first shot at a Java interface to libcurl. Many thanks to
Daniel Marell for tirelessly answering to all my basic Java questions. It
works, but it is still very basic.
Daniel (10 April 2001)
- The progress display could get silly when doing multiple file transfers, as
it wasn't properly reset between transfers!
- Discussions with Cris Bailiff who writes a Perl interface to libcurl, made
me add CURLOPT_HEADERFUNCTION. It can be used to set a separate callback
function for writing headers. Previously you could only set a different FILE
* when headers are written from within libcurl.
Daniel (7 April 2001)
- Andrés García fixed a problem in curl_escape() and pointed out a flaw in
the curl_easy_setopt man page.
