2013-02-10pop3: Added support for the STLS capability (Part Three)Steve Holme
Added honoring of the tls_supported flag when starting a TLS upgrade rather than unconditionally attempting it. If the use_ssl flag is set to CURLUSESSL_TRY and the server doesn't support TLS upgrades then the connection will continue to authenticate. If this flag is set to CURLUSESSL_ALL then the connection will complete with a failure as it did previously.
2013-02-10pop3: Added support for the STLS capability (Part Two)Steve Holme
Added sending of initial CAPA command before STLS is sent. This allows for the detection of the capability before trying to upgrade the connection.
2013-02-10pop3: Added support for the STLS capability (Part One)Steve Holme
Introduced detection of the STLS capability, in order to add support for TLS upgrades without unconditionally sending the STLS command.
2013-02-09pop3: Fixed SASL authentication capability detectionSteve Holme
Fixed the SASL capability detection to include the space character before the authentication mechanism list. Otherwise a capability such as SASLSOMETHING would be interpreted as enabling SASL and potentially trying to identify SOMETHING as a mechanism.
2013-02-09pop3: Fixed incorrect return value from pop3_endofresp()Steve Holme
Corrected an incorrect return value when -ERR is received from the server - introduced in commit b5bb61ee697b (June 2012).
2013-02-08pop3: Reworked pop3_endofresp() to simplify it littleSteve Holme
Reworked pop3_endofresp() to simplify it and provide consistency between imap and smtp.
2013-02-06email: Moved starttls code in separate functionsSteve Holme
To help maintain the readability of the code in imap.c, pop3.c and smtp.c moved the starttls code into state_starttls() functions.
2013-02-05email: Reworked comments in the endofresp() functionsSteve Holme
Tidied up the comments in the endofresp() functions to be more meaningful prior to release.
2013-02-04email: Provided extra comments following recent pop3/imap fixesSteve Holme
Provided additional clarification about the logic of the authenticate() functions following commit 6b6bdc83bd36 and b4270a9af1d0.
2013-02-04pop3.c: Updated variable names to use shorter / more readable variantSteve Holme
Tidied up code from commit 6b6bdc83bdUpdated where a few instances of the pop3c struct variable used the longer conndata struct rather than matching what other code in pop3_authenticate() used.
2013-02-03pop3: Fixed no known authentication mechanism when fallback is requiredSteve Holme
Fixed an issue where (lib)curl is compiled without support for a supported challenge-response based SASL authentication mechanism, such as CRAM-MD5 or NTLM, the server doesn't support the LOGIN or PLAIN mechanisms and (lib)curl doesn't fallback to APOP or Clear Text authentication. Bug: http://curl.haxx.se/mail/lib-2013-02/0004.html Reported by: Stanislav Ivochkin
2013-01-27pop3.c: Fixed unnecessary state change if starttls failsSteve Holme
The state machine should only be changed to POP3_STARTTLS when the STLS command has been successfully sent to the server.
2013-01-24pop3.c: Fixed failure detection during TLS upgradeSteve Holme
pop3_state_upgrade_tls() would attempt to incorrectly complete the upgrade to pop3s and start the CAPA command if Curl_ssl_connect_nonblocking() returned a failure code and if ssldone was set to TRUE. This would only happen when a non-blocking API hadn't been provided by the SSL implementation and curlssl_connect() was called underneath.
2013-01-23email: Removed unnecessary return statementsSteve Holme
Small tidy up to remove unnecessary return statements prior to the next fix.
2013-01-22email: Corrected references to SASL RFCSteve Holme
The most recent version of the SASL RFC is RFC4422 and not RFC2222 as previously documented.
2013-01-20pop3.c: Fixed conditional compilation of the apop response functionSteve Holme
Extended the fix from commit 8b15c84ea91e to additionally exclude pop3_state_apop_resp() if the CURL_DISABLE_CRYPTO_AUTH flag is defined.
2013-01-19email: General code tidy upSteve Holme
Corrected some function argument definitions to maximize the 80 character line length limit and be in keeping with the curl coding style.
2013-01-18pop3.c: Fixed a problem with pop3s connections not connecting properlySteve Holme
Fixed an issue where Curl_ssl_connect_nonblocking() wouldn't complete correctly and the ssldone flag wouldn't be set to true for pop3s based connections. Bug introduced in commit: 4ffb8a6398ed.
2013-01-17always-multi: always use non-blocking internalsDaniel Stenberg
Remove internal separated behavior of the easy vs multi intercace. curl_easy_perform() is now using the multi interface itself. Several minor multi interface quirks and bugs have been fixed in the process. Much help with debugging this has been provided by: Yang Tse
2013-01-09build: fix circular header inclusion with other packagesYang Tse
This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.
2013-01-08pop3: Added support for non-blocking SSL upgradeSteve Holme
Added support for asynchronous SSL upgrade when using the multi-interface.
2013-01-06pop3.c: Fixed default authentication detectionSteve Holme
Fixed an issue where a server may positively respond to the CAPA command but not list clear text as a valid authentication type.

2012-12-29pop3_doing: Applied debug info message when function failsSteve Holme
Applied the same debug message as used in smtp_doing() and imap_doing() when pop3_multi_statemach() fails.
2012-12-29pop3.c: Removed unnecessary POP3_STOP state changesSteve Holme
Removed unnecessary state changes in pop3_state_starttls_resp() following previous fix in IMAP module.
2012-12-28pop3.c: Minor code tidy upSteve Holme
Minor tidy up of comments and layout prior to next part of imap work.

2012-12-24pop3_doing: don't call pop3_dophase_done() if already failedDaniel Stenberg
... it also clobbered the 'result' return value so that it wouldn't return the error back to the parent function properly, which broke test 809 when run with 'multi-always'.
2012-12-14setup_once.h: refactor inclusion of <unistd.h> and <sys/socket.h>Yang Tse
Inclusion of top two most included header files now done in setup_once.h

2012-06-09pop3: Post apop feature code tidy upSteve Holme
2012-06-09pop3: Added support for apop authenticationSteve Holme
2012-06-09pop3: Enhanced the extended authentication mechanism detectionSteve Holme
Enhanced the authentication type / mechanism detection in preparation for the introduction of APOP support.
2012-06-09pop3.c: Fixed length of SASL checkSteve Holme
2012-06-08sasl: Re-factored mechanism constants in preparation for APOP workSteve Holme
2012-06-05pop3: Another small code tidy upSteve Holme
Missed some comments that we identified during the SMTP tidy up earlier.
2012-06-05email: Removed duplicated header fileSteve Holme
2012-06-04sasl: Renamed Curl_sasl_decode_ntlm_type2_message()Steve Holme
For consistency with other SASL based functions renamed this function to Curl_sasl_create_ntlm_type3_message() which better describes its usage.
2012-06-04pop3: Post authentication code tidy upSteve Holme
Corrected lines longer than 78 characters. Changed POP3_AUTH_FINAL to POP3_AUTH to match SMTP code now that the AUTH command is no longer sent on its own. Introduced some comments in data sending functions. Another attempt at trying to rational code and comment style.
2012-06-04pop3: Added support for sasl digest-md5 authenticationSteve Holme
2012-06-04pop3: Changed the sasl mechanism detection from auth to capaSteve Holme
Not all SASL enabled POP3 servers support the AUTH command on its own when trying to detect the supported mechanisms. As such changed the mechanism detection to use the CAPA command instead.
2012-06-03pop3: Added support for sasl cram-md5 authenticationSteve Holme
2012-06-03pop3.c: Added conditional compilation for NTLM function callsSteve Holme
Added USE_NTLM condition compilation around the NTLM functions called from pop3_statemach_act() introduced in commit 69f7156ad96877.
2012-06-03pop3: Fixed an issue with changes introduced in commit c267c53017bcSteve Holme
Because pop3_endofresp() is called for each line of data yet is not passed the line and line length, so we have to use the data pointed to by pp->linestart_resp which contains the whole packet, the mechanisms were being detected in one call yet the function would be called for each line of data. Using curl with verbose mode enabled would show that one line of data would be received in response to the AUTH command, before the AUTH <mechanism> command was sent to the server and then the next few lines of the original AUTH command would be displayed before the response from the AUTH <mechanism> command. This would then cause problems when parsing the CRAM-MD5 challenge data as extra data was contained in the buffer. Changed the parsing so that each line is checked for the mechanisms and the function returns FALSE until the whole of the AUTH response has been processed.
2012-06-02pop3.c:Corrected typo in commit 69ba0da8272dSteve Holme
2012-06-02pop3: Fixed the issue of having to supply the user name for all requestsSteve Holme
Previously it wasn't possible to connect to POP3 and not specify the user name as a CURLE_ACCESS_DENIED error would be returned. This error occurred because USER would be sent to the server with a blank user name if no mailbox user was specified as the server would reply with -ERR. This wasn't a problem prior to the 7.26.0 release but with the introduction of custom commands the user and/or application developer might want to issue a CAPA command without having to log in as a specific mailbox user. Additionally this fix won't send the newly introduced AUTH command if no user name is specified.
2012-06-02pop3.c: Small code tidy upSteve Holme
Corrected lines exceeding 78 characters. Repositioned some comments and added extra clarity.
