When Curl_do() returns failure, the connection pointer could be NULL so
the code path following needs to that that into account.
Bug: http://curl.haxx.se/mail/lib-2013-03/0062.html
Reported by: Eric Hu
No more use exit(3) but instead tell libcurl that no byte has been
written to let it return a `CURLE_WRITE_ERROR`. In addition, check
curl easy handle return code.
Moved the blocking state machine to the disconnect functions so that the
logout / quit functions are only responsible for sending the actual
command needed to logout or quit.
Additionally removed the hard return on failure.
Added an exception, for the STORE command, to the untagged response
processor in imap_endofresp() as servers will back respones containing
the FETCH keyword instead.
GCC specific adjustments:
- check __ILP32__ before 32 and 64bit processor architectures in
order to detect ILP32 programming model on 64 bit processors
which, of course, also support LP64 programming model, when using
gcc 4.7 or newer.
- keep 32bit processor architecture checks in order to support gcc
versions older than 4.7 which don't define __ILP32__
- check __LP64__ for gcc 3.3 and newer, while keeping 64bit processor
architecture checks for older versions which don't define __LP64__
The list of unsafe functions currently consists of sprintf, vsprintf,
strcat, strncat and gets.
Subsequently, some existing code needed updating to avoid warnings on
this.
Enriched IMAP capabilities of ftpserver.pl in order to be able to
add tests for the new IMAP features.
* Added support for APPEND - Saves uploaded data to log/upload.$testno
* Added support for LIST - Returns the contents of <reply/> section in
the current test, like e.g FETCH.
* Added support for STORE - Returns hardcoded updated flags
* Changed handling of SELECT - Returns much more information in the
usual set of untagged responses; uses hardcoded data from an example
in the IMAP RFC
* Changed handling of FETCH - Fixed response format
As the UID has to be specified by the user for the FETCH command to work
correctly, added a check to imap_fetch(), although strictly speaking it
is protected by the call from imap_perform().
The option needs to be set on the SSL socket. Setting it on the model
takes no effect. Note that the non-blocking mode is still not enabled
for the handshake because the code is not yet ready for that.
