By always returning the md5 for an empty body when auth-int is asked
for, libcurl now at least sometimes does the right thing.

Allow less room for "triggered too early" mistakes by applications /
timers on non-windows platforms. Starting now, we assume that a timeout
call is never made earlier than 3 milliseconds before the actual
timeout. This greatly improves timeout accuracy on Linux.

In the pkcs12 code, we get a list of x509 records returned from
PKCS12_parse but when iterating over the list and passing each to
SSL_CTX_add_extra_chain_cert() we didn't also properly remove them from
the "stack", which made them get freed twice (both in sk_X509_pop_free()
and then later in SSL_CTX_free).
This isn't really documented anywhere...

commit 29bf0598aa introduced a problem when the "internal" timeout is
prefered to the given if shorter, as it didn't consider the case where
-1 was returned. Now the internal timeout is only considered if not -1.

If the multi handle's pending timeout is less than what is passed into
this function, it will now opt to use the shorter time anyway since it
is a very good hint that the handle wants to process something in a
shorter time than what otherwise would happen.
curl_multi_wait.3 was updated accordingly to clarify
This is the reason for bug #1224

Bug: http://curl.haxx.se/bug/view.cgi?id=1230
We found that in specific cases if the connection is abruptly closed,
the underlying socket is listed in a close_wait state. We continue to
call the curl_multi_perform, curl_mutli_fdset etc. None of these APIs
report the socket closed / connection finished. Since we have cases
where the multi connection is only used once, this can pose a problem
for us. I've read that if another connection was to come in, curl would
see the socket as bad and attempt to close it at that time -
unfortunately, this does not work for us.
I found that in specific situations, if SSL_write returns 0, curl did
not recognize the socket as closed (or errored out) and did not report
it to the application. I believe we need to change the code slightly, to
check if ssl_write returns 0. If so, treat it as an error - the same as
a negative return code.
For OpenSSL - the ssl_write documentation is here:
http://www.openssl.org/docs/ssl/SSL_write.html
1 - don't skip host names with a colon in them in an attempt to bail out
on HTTP headers in the cookie file parser. It was only a shortcut anyway
and trying to parse a file with HTTP headers will still be handled, only
slightly slower.
2 - don't skip domain names based on number of dots. The original
netscape cookie spec had this oddity mentioned and while our code
decreased the check to only check for two, the existing cookie spec has
no such dot counting required.

I found a bug which cURL sends cookies to the path not to aim at.
For example:
- cURL sends a request to http://example.fake/hoge/
- server returns cookie which with path=/hoge;
the point is there is NOT the '/' end of path string.
- cURL sends a request to http://example.fake/hogege/ with the cookie.
The reason for this old "feature" is because that behavior is what is
described in the original netscape cookie spec:
http://curl.haxx.se/rfc/cookie_spec.html
The current cookie spec (RFC6265) clarifies the situation:
http://tools.ietf.org/html/rfc6265#section-5.2.4
This reverts commit 8ec2cb5544.
We don't have any code anywhere in libcurl (or the curl tool) that use
wcsdup so there's no such memory use to track. It seems to cause mild
problems with the Borland compiler though that we may avoid by reverting
this change again.

If the mail sent during the transfer contains a terminating <CRLF> then
we should not send the first <CRLF> of the EOB as specified in RFC-5321.
Additionally don't send the <CRLF> if there is "no mail data" as the
DATA command already includes it.
The code within #ifdef HAVE_SOCKADDR_IN6_SIN6_SCOPE_ID wrongly had two
closing braces when it should only have one, so builds without that
define would fail.
Bug: http://curl.haxx.se/mail/lib-2013-05/0000.html
The curl command line utility would display the the completed progress
bar with a percentage of zero as the progress routines didn't know the
size of the transfer.
Removed the hard returns from imap and pop3 by using the same style for
sending the authentication string as smtp. Moved the "Other mechanisms
not supported" check in smtp to match that of imap and pop3 to provide
consistency between the three email protocols.
Users using the Secure Transport (darwinssl) back-end can now use a
certificate and private key to authenticate with a site using TLS. Because
Apple's security system is based around the keychain and does not have any
non-public function to create a SecIdentityRef data structure from data
loaded outside of the Keychain, the certificate and private key have to be
loaded into the Keychain first (using the certtool command line tool or
the Security framework's C API) before we can find it and use it.
In addition to checking for the SASL-IR capability the user can override
the sending of the client's initial response in the AUTHENTICATION
command with the use of CURLOPT_SASL_IR should the server erroneously
not report SASL-IR when it does support it.
Updated the default behaviour of sending the client's initial response in the AUTH
command to not send it and added support for CURLOPT_SASL_IR to allow the user to
specify including the response.

By introducing an internal alternative to curl_multi_init() that accepts
parameters to set the hash sizes, easy handles will now use tiny socket
and connection hash tables since it will only ever add a single easy
handle to that multi handle.
This decreased the number mallocs in test 40 (which is a rather simple
and typical easy interface use case) from 1142 to 138. The maximum
amount of memory allocated used went down from 118969 to 78805.
When connecting back to an FTP server after having sent PASV/EPSV,
libcurl sometimes didn't use the proxy properly even though the proxy
was used for the initial connect.
The function wrongly checked for the CURLOPT_PROXY variable to be set,
which made it act wrongly if the proxy information was set with an
environment variable.
Added test case 711 to verify (based on 707 which uses --socks5). Also
added test712 to verify another variation of setting the proxy: with
--proxy socks5://

... in order to prevent an artificial timeout event based on stale
speed-check data from a previous network transfer. This commit fixes
a regression caused by 9dd85bced5.
Bug: https://bugzilla.redhat.com/906031
Fixed an issue in parse_proxy(), introduced in commit 11332577b3,
where an empty username or password (For example: http://:@example.com)
would cause a crash.
There is no need to perform separate clearing of data if a NULL option
pointer is passed in. Instead this operation can be performed by simply
not calling parse_login_details() and letting the rest of the code do
the work.
setstropt_userpwd() was calling setstropt() in commit fddb7b44a7 to
set each of the login details which would duplicate the strings and
subsequently cause a memory leak.
In addition to parsing the optional login options from the URL, added
support for parsing them from CURLOPT_USERPWD, to allow the following
supported command line:
--user username:password;options
Added bounds checking when searching for the separator characters within
the login string as this string may not be NULL terminated (For example
it is the login part of a URL). We do this in preference to allocating a
new string to copy the login details into which could then be passed to
parse_login_details() for performance reasons.
As well as parsing the username and password from the URL, added support
for parsing the optional options part from the login details, to allow
the following supported URL format:
schema://username:password;options@example.com/path?q=foobar
This will only be used by IMAP, POP3 and SMTP at present but any
protocol that may be given login options in the URL will be able to
add support for them.
...instead of the 220 we otherwise expect.
Made the ftpserver.pl support sending a custom "welcome" and then
created test 1219 to verify this fix with such a 230 welcome.

The previously applied patch didnt work on Windows; we cant rely
on shell commands like 'echo' since they act diffently on each
platform and each shell.
In order to keep this script platform-independent the code must

prefix with a comment before the path instead of after it as is
otherwise the norm.
Failing to parse this, several otherwise legitimate use cases break.
