Version *upcoming* 7.4
Daniel (9 October 2000)
- Georg Horn provided a source example that proved a memory leak in libcurl.
I added simple memory debugging facilities and now we can make libcurl log
all memory fiddling functions. An additional perl script is used to analyze
the output logfile and to match malloc()s with free()s etc. The memory leak
Georg found turned out to be the main cookie struct that cookie_cleanup()
didn't free!
Daniel (8 October 2000)
- Georg Horn found a GetHost() problem. It turned out it never assigned the
pointer in the third argument properly! This could make a crash, or at best
a memory leak!
Version 7.4 pre4
Daniel (6 October 2000)
- Is the -F post following the RFCX 1867 spec? We had this dicussion on the
mailing list since it appears curl can't post -F form posts to a PHP
receiver...
- Domenico Andreoli found out that the long option '--proxy' wasn't working
anymore! The option parser got confused when I added the --proxytunnel for
7.3. This was indeed a very old flaw that hasn't turned up until now...
- Jörn Hartroth provided patches, updated makefiles and two new files for DLL
stuff on win32. He also pointed out that lib source files were compiled with
-I../src which isn't only wrong but plain stupid!
- Troels Walsted Hansen fixed a problem with HTTP resume. Curl previously used
a local variable badly, that could lead to crashes.
Version 7.4 pre3
Daniel (4 October 2000)
- More docs written. The curl_easy_getinfo.3 man page is now pretty accurate,
as is the -w section in curl.1. I added two options to enable the user to
get information about the received headers' size and the size of the HTTP
request. T. Bharath requested them.
Daniel (3 October 2000)
- Corrected a sever free() before use in the new add_buffer_send()! ;-)
Version 7.4 pre2
Daniel (3 October 2000)
- Jason S. Priebe sent me patches that changed the way curl issues HTTP
requests. The entire request is now issued in one single shot. It didn't do
this previously, and it has turned out that since the common browsers do it
this way, some sites have turned out to work with browsers but not with
curl! Although this is not a client-side problem, we want to be able to
fully emulate browsers, and thus we have now adjusted the networking layer
to slightly more appear as a browser. I adjusted Jason's patch, the faults
are probably mine.
Daniel (2 October 2000)
- Anyone who ever uploaded data with curl on a slow link has noticed that the
progess meter is updated very infrequently. That is due to the large buffer
size curl is using. It reads 50Kb and sends it, updates the progress meter
and loops. 50Kb is very much on a slow link, although it is pretty neat to
use on a fast one.
I've now made an adjustment that makes curl use a 2Kb buffer for uploads to
start with. If curl's average upload speed is faster than buffer size bytes
per second, curl will increase the used buffer size up to max 50Kb. It
should make the progress meter work better.
Version 7.4 pre1
Daniel (29 September 2000)
- Ripped out the -w stuff from the library and put in the curl tool. It gets
all the relevant info from the library using the new curl_easy_getinfo()
function.
- brad at openbsd.org mailed me a patch that corrected my kerberos mistake and
removed a compiler warning from hostip.c that OpenBSD people get.
Daniel (28 September 2000)
- Of course (I should probably get punished somehow) I didn't properly correct
the #include lines for the base64 stuff in the kerberos sources in the just
released 7.3 package. They still include the *_krb.h files! Now, the error
is sooo very easy to spot and fix so I won't bother with a quick bug fix
release. I'll post a patch whenever one is needed instead. It'll be
available in the CVS in a few minutes anyway.
Daniel (28 September 2000)
- Removed the base64_krb.[ch] files. They've now replaced the former
base64.[ch] files.
Daniel (26 September 2000)
- Updated some docs.
- I changed the OpenSSL fix to work with older versions as well. The posted
patch was only working with 0.9.6 and no older ones.
Version 7.3-pre8
Daniel (25 September 2000)
- Erdmut Pfeifer informed us that curl didn't build with OpenSSL 0.9.6 and
showed us what needed to get patched in order to make it build properly
again.
- Dirk Kruschewski found a bug in the cookie parser. I made an alternative
approach to the solution Dirk himself suggested. The bug made a cookie
header that didn't end with a trailing semicolon to not get parsed.
- I've marked -c and -t deprecated now. If you use any of them, curl will tell
you to use "-C -" or "-T -" instead. I don't think occupying two letters for
nearly identical functions is good use. Also, -T - kind of follows the curl
tradition of using - for stdin where a file name is expected.
Daniel (23 September 2000)
- Martin Hedenfalk provided the patch that finally made the krb4 ftp upload
work!
Daniel (21 September 2000)
- The kerberos code is not quite thread-safe yet. There are a few more globals
that need to be take care of. Let's get the upload working first!
Daniel (20 September 2000)
- Richard Prescott solved another name lookup buffer size problem. I took this
opportunity to rewrite the GetHost() function. With these large buffer
sizes, I think keeping them as local arrays quickly turn ugly. I now use

malloc() to get the buffer memory. Thanks to this, I now can realloc() to a
large buffer in case of demand (errno == ERANGE) in case a solution like
that would become necessary. I still want to avoid that kind of nastiness.
- Tried to compile and run curl on Linux for alpha and FreeBSD for alpha. Went
as smooth as it could.
- Added a docs/examples directory with two tiny example sources that show how
to use libcurl. I hope users will supply me with more useful examples
further on.
- Applied a patch by Jörn Hartroth to no longer use the word 'inteface' in the
config struct in the src/main.c file since certain compilers have that word
"reservered". I figure that is some kind of C++ decease.
- Updated the curl.1 man page with --interface and --krb4.
- Modified the base64Encode() function to work like the kerberos one, so that
I could remove the use of that. There is no need for *two* base64 encoding
functions! ;-)
Version 7.3pre5
Daniel (19 September 2000)
- The kerberos4-layer source code that is much "influenced" by the original
krb4 source code, through yafc into curl, was using quite a lot of global
variables. libcurl can't work properly with globals like that why I had to
clean up almost every function in the new security.c to make them use
connection specific variables instead of the globals. I just hope I didn't
destroy anything now... :-) configure updated, version string now reflects
krb4 built-in. It almost works now. Only uploads are still being naughty.
Version 7.3pre3
Daniel (18 September 2000)
- Martin Hedenfalk supplied a major patch that introduces krb4-ftp support to
curl. Martin is the primary author of the ftp client named yafc and he did
not hesitate to help us implement this when I asked him. Many and sincere
thanks to a splendid effort. It didn't even take many hours!
- Stephen Kick supplied a big patch that introduces the --interface flag to
the curl tool and CURLOPT_INTERFACE for libcurl. It allows you to specify an
outgoing interface to use for your request. This may not work on all
platforms. This needs testing.
- Richard Prescott noticed that curl on Tru64 unix could core dumped if the
name didn't resolve properly. This was due to the GetHost() function not
returning an error even though it failed on some platforms!
Daniel (15 September 2000)
- Updated all sorts of documents in regards to the new proxytunnel support.
Version 7.3pre2
Daniel (15 September 2000)
- Kai-Uwe Rommel pointed out a problem in the httpproxytunnel stuff for ftp.
Adjusted it. Added better info message when setting up the tunnel and the
pasv message when doing the second connect.
Daniel (15 September 2000)
- libcurl now allows "httpproxytunnel" to an arbitrary host and port name. The
second connection on ftp needed that.
- TheArtOfHTTPScripting was corrected all over. I both type and spell really
Loading full blame...
