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.
reported, the define is used by the configure script and is assumed to use
the 0xYYXXZZ format. This made "curl-config --vernum" fail in the 7.15.0
release version.
