an app can use to let libcurl only connect to a remote host and then extract
the socket from libcurl. libcurl will then not attempt to do any transfer at
all after the connect is done.
with re-used FTP connections. If the second request on the same connection was
set not to fetch a "body", libcurl could get confused and consider it an
attempt to use a dead connection and would go acting mighty strange.
curl tool with --local-port. Plain and simply set the range of ports to bind
the local end of connections to. Implemented on to popular demand.
Not extensively tested. Please let me know how it works.
connection setup as a follow-redirect. It turns out 1) this fails when a FTP
connection is re-setup and 2) it does make the max-redirs counter behave
wrong. This fix was not verified since the reporter vanished, but I believe
this is the right fix nonetheless.
even after EPSV returned a positive response code, if libcurl failed to
connect to the port number the EPSV response said. Obviously some people are
going through protocol-sensitive firewalls (or similar) that don't understand
EPSV and then they don't allow the second connection unless PASV was
used. This also called for a minor fix of test case 238.
(CURLOPT_FTPPORT) didn't work for ipv6-enabed curls if the IP wasn't a
"native" IP while it works fine for ipv6-disabled builds!
In the process of fixing this, I removed the support for LPRT since I can't
think of many reasons to keep doing it and asking on the mailing list didn't
reveal anyone else that could either. The code that sends EPRT and PORT is
now also a lot simpler than before (IMHO).
into a counter, and thus you can now do multiple curl_global_init() and you
are then supposed to do the same amount of calls to curl_global_cleanup().
Bryan also updated the docs accordingly.
given subdirs, libcurl would still "remember" the full path as if it is the
current directory libcurl is in so that the next curl_easy_perform() would
get really confused if it tried the same path again - as it would not issue
any CWD commands at all, assuming it is already in the "proper" dir.
Starting now, a failed CWD command sets a flag that prevents the path to be
"remembered" after returning.
http://www.greenend.org.uk/rjk/2001/06/poll.html and further tests by Eugene
Kotlyarov, we now know that cygwin's poll returns only POLLHUP on remote
connection closure so we check for that case (too) and re-enable poll for
cygwin builds.
version of libcurl with different Windows versions. Current version of
libcurl imports SSPI functions from secur32.dll. However, under Windows NT
4.0 these functions are located in security.dll, under Windows 9x - in
secur32.dll and Windows 2000 and XP contains both these DLLs (security.dll
just forwards calls to secur32.dll).
Dmitry's patch loads proper library dynamically depending on Windows
version. Function InitSecurityInterface() is used to obtain pointers to all
of SSPI function in one structure.

The LDAP code in libcurl can't handle LDAP servers of LDAPv3 nor binary
attributes in LDAP objects. So, I made a quick patch to address these
problems.
The solution is simple: if we connect to an LDAP server, first try LDAPv3
(which is the preferred protocol as of now) and then fall back to LDAPv2.
In case of binary attributes, we first convert them to base64, just like the
openldap client does. It uses ldap_get_values_len() instead of
ldap_get_values() to be able to retrieve binary attributes correctly. I
defined the necessary LDAP macros in lib/ldap.c to be able to compile
libcurl without the presence of libldap
(http://curl.haxx.se/bug/view.cgi?id=1338648) which really is more of a
feature request, but anyway. It pointed out that --max-redirs did not allow
it to be set to 0, which then would return an error code on the first
Location: found. Based on Nis' patch, now libcurl supports CURLOPT_MAXREDIRS
set to 0, or -1 for infinity. Added test case 274 to verify.
(http://curl.haxx.se/bug/view.cgi?id=1337723) that curl could not upload
binary data from stdin on Windows if the data contained control-Z (hex 1a)
since that is treated as end-of-file when read in text mode. Gisle Vanem
pointed out the fix, and I made both -T and --data-binary take advantage of
it.
in the man page, curl would send an invalid HTTP Range: header. The correct
way would be to use "-r [number]-" or even "-r -[number]". Starting now,
curl will warn if this is discovered, and automatically append a dash to the
range before passing it to libcurl.
#1334338 (http://curl.haxx.se/bug/view.cgi?id=1334338). When reading an SSL
stream from a server and the server requests a "rehandshake", the current
code simply returns this as an error. I have no good way to test this, but
I've added a crude attempt of dealing with this situation slightly better -
it makes a blocking handshake if this happens. Done like this because fixing
this the "proper" way (that would handshake asynchronously) will require
quite some work and I really need a good way to test this to do such a
change.
(wrongly) sends *two* WWW-Authenticate headers for Digest. While this should
never happen in a sane world, libcurl previously got into an infinite loop
when this occurred. Dave added test 273 to verify this.
