With the curl memory tracking feature decoupled from the debug build feature,
CURLDEBUG and DEBUGBUILD preprocessor symbol definitions are used as follows:
CURLDEBUG used for curl debug memory tracking specific code (--enable-curldebug)
DEBUGBUILD used for debug enabled specific code (--enable-debug)
not in the mood enough to fight this now.
65. When doing FTP over a socks proxy or CONNECT through HTTP proxy and the
multi interface is used, libcurl will fail if the (passive) TCP connection
for the data transfer isn't more or less instant as the code does not
properly wait for the connect to be confirmed. See test case 564 for a first
shot at a test case.
If the CURLOPT_PORT option is used on an FTP URL like
"ftp://example.com/file;type=A" the ";type=A" is stripped off.
I added test case 562 to verify, only to find out that I couldn't repeat
this bug so I hereby consider it not a bug anymore!
Chen pointed out how curl couldn't upload with resume when reading from a
pipe.
This ended up with the introduction of a new return code for the
CURLOPT_SEEKFUNCTION callback that basically says that the seek failed but
that libcurl may try to resolve the situation anyway. In our case this means
libcurl will attempt to instead read that much data from the stream instead
of seeking and that way curl can now upload with resume when data is read
from a stream!
Koenig pointed out that the man page didn't tell that the *_proxy
environment variables can be specified lower case or UPPER CASE and the
lower case takes precedence,
for any further requests or transfers. The work-around is then to close that
handle with curl_easy_cleanup() and create a new. Some more details:

and 1 on fatal errors. Previously it only mentioned non-zero on fatal
errors. This is a slight change in meaning, but it follows what we've done
elsewhere before and it opens up for LOTS of more useful return codes
whenever we can think of them...
(http://curl.haxx.se/docs/adv_20090303.html also known as CVE-2009-0037) in
which previous libcurl versions (by design) can be tricked to access an
arbitrary local/different file instead of a remote one when
CURLOPT_FOLLOWLOCATION is enabled. This flaw is now fixed in this release
together this the addition of two new setopt options for controlling this
new behavior:
o CURLOPT_REDIR_PROTOCOLS controls what protocols libcurl is allowed to
follow to when CURLOPT_FOLLOWLOCATION is enabled. By default, this option
excludes the FILE and SCP protocols and thus you nee to explicitly allow
them in your app if you really want that behavior.
o CURLOPT_PROTOCOLS controls what protocol(s) libcurl is allowed to fetch
using the primary URL option. This is useful if you want to allow a user or
other outsiders control what URL to pass to libcurl and yet not allow all
protocols libcurl may have been built to support.
CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD return
-1 if the sizes aren't know. Previously these returned 0, make it impossible
to detect the difference between actually zero and unknown.
