- Igor Novoseltsev reported a problem with the multi socket API and using
timeouts and timers. It boiled down to a problem with libcurl's use of
GetTickCount() interally to figure out the current time, while Igor's own
application code used another function call.
It made his app call the socket API timeout function a bit _before_ libcurl
would consider the timeout to trigger, and that could easily lead to
timeouts or stalls in the app. It seems GetTickCount() in general often has
no better resolution than 16ms and switching to the alternative function
QueryPerformanceCounter has its share of problems:

We address this problem by simply having libcurl treat timers that already
has occured or will occur within 40ms subject for treatment. I'm confident
that there are other implementations and operating systems with similarly in
accurate timer functions so it makes sense to have applied generically and I
don't believe we sacrifice much by adding a 40ms inaccuracy on these
timeouts.

- added a new test for CRL support (test313)
- Tor Arntsen changed the alternative definition of bool to use enum instead
of unsigned char.
Daniel Stenberg (25 May 2010)
- Julien Chaffraix fixed the warning seen when compiling lib/rtmp.c: one
unused variables, several unused arguments and some missing #include.
- Julien Chaffraix fixed 2 OOM errors: a missing NULL-check in
lib/http_negociate.c and a potential NULL dereferencing in lib/splay.c
- Howard Chu brought a patch that makes the LDAP code much cleaner, nicer and
in general being a better libcurl citizen. If a new enough OpenLDAP version
is detect, the new and shiny lib/openldap.c code is then used instead of the
old cruft.
- Eric Mertens posted bug #3003705: when we made TFTP use the correct timeout
option when sent to the server (fixed May 18th 2010) it became obvious that
libcurl used invalid timeout values (300 by default while the RFC allows
nothing above 255). While of course it is obvious that as TFTP has worked
thus far without being able to set timeout at all, just removing the setting
wouldn't make any difference in behavior. I decided to still keep it (but
fix the problem) as it now actually allows for easier (future) customization
of the timeout.

- Douglas Kilpatrick filed bug report #3004787 and pointed out that the TFTP
code didn't handle block id wraps correctly. His suggested fix inspired the
fix I committed.

Daniel Stenberg (20 May 2010)
- Tanguy Fautre brought a fix to allow curl to build with Microsoft VC10.
Daniel Stenberg (18 May 2010)
- Eric Mertens posted bug report #3003005 pointing out that the libcurl TFTP
code was not sending the timeout option properly to the server, and
suggested a fix.

Kamil Dudka (16 May 2010)
- Pavel Raiskup introduced a new option CURLOPT_FNMATCH_DATA in order to pass
a custom data pointer to the callback specified by CURLOPT_FNMATCH_FUNCTION.
Daniel Stenberg (14 May 2010)
- John-Mark Bell filed bug #3000052 that identified a problem (with an
associated patch) with the OpenSSL handshake state machine when the multi
interface is used:
Performing an https request using a curl multi handle and using select or
epoll to wait for events results in a hang. It appears that the cause is the
fix for bug #2958179, which makes ossl_connect_common unconditionally return
from the step 2 loop when fetching from a multi handle.
When ossl_connect_step2 has completed, it updates connssl->connecting_state
to ssl_connect_3. ossl_connect_common will then return to the caller, as a
multi handle is in use. Eventually, the client code will call
curl_multi_fdset to obtain an updated fdset to select or epoll on. For https
requests, curl_multi_fdset will cause https_getsock to be called.
https_getsock will only return a socket handle if the connecting_state is
ssl_connect_2_reading or ssl_connect_2_writing. Therefore, the client will
never obtain a valid fdset, and thus not drive the multi handle, resulting
in a hang.

- Sebastian V reported bug #3000056 identifying a problem with redirect
following. It showed that when curl followed redirects it didn't properly
ignore the response body of the 30X response if that response was using
compressed Content-Encoding!

Daniel Stenberg (12 May 2010)
- Howard Chu brought support for RTMP. This is powered by the underlying
librtmp library. It supports a range of variations and "sub-protocols"
within the RTMP family.
- Pavel Raiskup brought support for FTP directory wildcard matching to allow
selective downloading. To provide that, a set of new options were added:
CURLOPT_WILDCARDMATCH
CURLOPT_CHUNK_BGN_FUNCTION
CURLOPT_CHUNK_END_FUNCTION
CURLOPT_CHUNK_DATA
CURLOPT_FNMATCH_FUNCTION
There were also a set of new tests added (574 - 577) to verify this.
Kamil Dudka (11 May 2010)
- CRL support in libcurl-NSS has been completely broken. Now it works. Original
bug report: https://bugzilla.redhat.com/581926
- Dirk Manske reported a regression. When connecting with the multi interface,
there were situations where libcurl wouldn't store connect time correctly as
it used to (and is documented to) do.
Using his fine sample program we could repeat it, and I wrote up test case
573 using that code. The problem does not easily show itself using the local
test suite though.
The fix, also as suggested by Dirk, is a bit on the ugly side as it adds yet
another call to Curl_verboseconnect() and setting the TIMER_CONNECT time.
That situation is subject for some closer inspection in the future.
- Howard Chu split the I/O handling functions into private handlers.
Howard Chu brought the bulk work of this patch that properly moves out the
sending and recving of data to the parts of the code that are properly
responsible for the various ways of doing so.
Daniel Stenberg assisted with polishing a few bits and fixed some minor
flaws in the original patch.
Another upside of this patch is that we now abuse CURLcodes less with the
"magic" -1 return codes and instead use CURLE_AGAIN more consistently.
Daniel Stenberg (5 May 2010)
- Hoi-Ho Chan introduced support for using the PolarSSL library. You control
this with the new configure option --with-polarssl.
Daniel Stenberg (29 Apr 2010)
- Ben Greear made telnet a lot better/easier to use by an application:
The main change is to allow input from user-specified methods, when they are
specified with CURLOPT_READFUNCTION. All calls to fflush(stdout) in
telnet.c were removed, which makes using 'curl telnet://foo.com' painful
since prompts and other data are not always returned to the user promptly.
Use 'curl --no-buffer telnet://foo.com' instead. In general, the user
should have their CURLOPT_WRITEFUNCTION do a fflush for interactive use.
Also fix assumption that reading from stdin never returns < 0.
Old code could crash in that case.
Call progress functions in telnet main loop.
Daniel Stenberg (26 Apr 2010)
- Make use of the libssh2_init/exit functions that libssh2 added in version
1.2.5. Using them will improve how libcurl works in threaded situations when
SCP and SFTP are transfered.
Daniel Stenberg (25 Apr 2010)
- Based on work by Kamil Dudka, I've introduced the new configure option
--enable-threaded-resolver. When used, the configure script will check for
pthreads and if around, it will build libcurl to use pthreads to do name
resolving in a threaded manner. Note that this is just a fix to offer an
option that can enable the code that already included. The threader resolver
code was mostly added on Jan 26 2010.
Daniel Stenberg (24 Apr 2010)
- Alex Bligh introduced the --proto and -proto-redir options that limit what
protocols curl accepts for the requests and when following redirects.
Kamil Dudka (24 Apr 2010)
- Fixed test536 in order to not fail with threaded DNS resolver and tweaked
comments in certain examples using curl_multi_fdset().
- Fixed SSL handshake timeout underflow in libcurl-NSS, which caused test405
to hang on a slow machine.
Daniel Stenberg (21 Apr 2010)
- The -O option caused curl to crash on windows and DOS due to the tool
writing out of boundary memory.
