2012-05-28pop3: Introduced the continue response in pop3_endofresp()Steve Holme
2012-05-28pop3: Changed response code from O and E to + and -Steve Holme
The POP3 protocol doesn't really have the concept of error codes and uses +, +OK and -ERR in response to commands to indicate continue, success and error. The AUTH command is one of those commands that requires multiple pieces of data to be sent to the server where the server will respond with + as part of the handshaking. This meant changing the values before continuing with the next stage of adding authentication support.
2012-05-28pop3: Small code tidy up following authentication work so farSteve Holme
Changed the order of the state machine to match the order of actual events. Reworked some comments and function parameter positioning that I missed the other day.
2012-05-27pop3: remove variable-not-used warningsDaniel Stenberg
2012-05-27pop3: Added support for SASL based authentication mechanism detectionSteve Holme
Added support for detecting the supported SASL authentication mechanisms via the AUTH command. There are two ways of detecting them, either by using the AUTH command, that will return -ERR if not supported or by using the CAPA command which will return SASL and the list of mechanisms if supported, not include SASL if SASL authentication is not supported or -ERR if the CAPA command is not supported. As such it seems simpler to use the AUTH command and fallback to normal clear text authentication if the the command is not supported. Additionally updated the test cases to return -ERR when the AUTH command is encountered. Additional test cases will be added when support for the individual authentication mechanisms is added.
2012-05-27pop3: remove trailing whitespaceDaniel Stenberg
2012-05-27pop3: Code tidy up before the introduction of authentication codeSteve Holme
Moved EOB definition into header file. Switched the logic around in pop3_endofresp() to allow for the introduction of auth-mechanism detection. Repositioned second and third function variables where they will fit within the 78 character line limit. Tidied up some comments.
2012-04-02pop3: Reworked the command sending and handlingSteve Holme
Reworked the command sending from two specific LIST and RETR command functions into a single command based function as well as the two associated response handlers into a generic command handler.
2012-03-31pop3: Added support for additional pop3 commandsSteve Holme
This feature allows the user to specify and use additional POP3 commands such as UIDL and DELE via libcurl's CURLOPT_CUSTOMREQUEST or curl's -X command line option.
2012-03-25pop3.c: Corrected problem with state() introduced in 01690ed2bce5Steve Holme
2012-03-25pop.c: Small code tidy upSteve Holme
2012-03-25pop3: Removed the need for the single message LIST command handlerSteve Holme
Simplified the code to remove the need for a separate "LIST <msg id>" command handler and state machine and instead use the LIST command handler for both operations.
2012-03-24pop3.c: Code policing and tidy upSteve Holme
Corrected character and line spacing and re-ordered list and retr functions based on the order of their state machines.
2012-03-24email: Moved server greeting responses into separate functionsSteve Holme
Moved the server greeting response handling code from the statemach_act functions to separate response functions. This makes the code simpler to follow and provides consistency with the other responses that are handled here.
2012-03-24pop3.c: Fixed body data being written when CURLOPT_NOBODY is specifiedSteve Holme
Body data would be forwarded to the client application in both the RETR and LIST commands even if CURLOPT_NOBODY was specified.
2012-03-09includes: remove inclusion of unused file http_proxy.hDaniel Stenberg
2012-03-08CONNECT: made generically not per-protocolDaniel Stenberg
Curl_protocol_connect() now does the tunneling through the HTTP proxy if requested instead of letting each protocol specific connection function do it.
2012-02-19pop3.c: Fixed drop of final CRLF in EOB checkingSteve Holme
Curl_pop3_write() would drop the final CRLF of a message as it was considered part of the EOB as opposed to part of the message. Whilst the EOB sequence needs to be searched for by the function only the final 3 characters should be removed as per RFC-1939 section 3. Reported by: Rich Gray Bug: http://curl.haxx.se/mail/lib-2012-02/0051.html
2012-01-24URL sanitize: reject URLs containing bad dataDaniel Stenberg
Protocols (IMAP, POP3 and SMTP) that use the path part of a URL in a decoded manner now use the new Curl_urldecode() function to reject URLs with embedded control codes (anything that is or decodes to a byte value less than 32). URLs containing such codes could easily otherwise be used to do harm and allow users to do unintended actions with otherwise innocent tools and applications. Like for example using a URL like pop3://pop3.example.com/1%0d%0aDELE%201 when the app wants a URL to get a mail and instead this would delete one. This flaw is considered a security vulnerability: CVE-2012-0036 Security advisory at: http://curl.haxx.se/docs/adv_20120124.html Reported by: Dan Fandrich
2012-01-04Fixed use of CURLUSESSL_TRY for POP3 and IMAP based connections.Steve Holme
Fixed a problem in POP3 and IMAP where a connection would fail when CURLUSESSL_TRY was specified for a server that didn't support SSL/TLS connections rather than continuing.
2012-01-04Fixed incorrect error code being returned in STARTTLSSteve Holme
The STARTTLS response code in SMTP, POP3 and IMAP would return CURLE_LOGIN_DENIED rather than CURLE_USE_SSL_FAILED when SSL/TLS was not available on the server. Reported by: Gokhan Sengun Bug: http://curl.haxx.se/mail/lib-2012-01/0018.html
2011-12-13pop3.c: fix compiler warning variable may be used uninitializedYang Tse
2011-12-01POP3: fixed escaped dot not being striped outSteve Holme
Changed the eob detection to work across the whole of the buffer so that lines that begin with a dot (which the server will have escaped) are passed to the client application correctly.
2011-11-29pop3.c: fix compiler warningYang Tse
2011-11-29POP3: detect when LIST returns no mailsDaniel Stenberg
By making sure the function can detect an "end of body" sequence immediately on the first line, test 811 is now enabled.
2011-11-29POP3: fix end of body detectionDaniel Stenberg
Curl_pop3_write() now has a state machine that scans for the end of a POP3 body so that the CR LF '.' CR LF sequence can come in everything from one up to five subsequent packets. Test case 810 is modified to use SLOWDOWN which makes the server pause between each single byte and thus makes the POP3 body get sent to curl basically one byte at a time.
2011-11-24query-part: ignore the URI part for given protocolsJonas Schnelli
By setting PROTOPT_NOURLQUERY in the protocol handler struct, the protocol will get the "query part" of the URL cut off before the data is handled by the protocol-specific code. This makes libcurl adhere to RFC3986 section 2.2. Test 1220 is added to verify a file:// URL with query-part.
2011-11-03rename ftp_ssl: the struct field is used for many protocolsDaniel Stenberg
Now called 'use_ssl' instead, which better matches the current CURLOPT name and since the option is used for all pingpong protocols (at least) it makes sense to not use 'ftp' in the name.
2011-10-21curl_multi_fdset: correct fdset with FTP PORT useDaniel Stenberg
After a PORT has been issued, and the multi handle would switch to the CURLM_STATE_DO_MORE state (which is unique for FTP), libcurl would return the wrong fdset to wait for when curl_multi_fdset() is called. The code would blindly assume that it was waiting for a connect of the second connection, while that isn't true immediately after the PORT command. Also, the function multi.c:domore_getsock() was highly FTP-centric and therefore ugly to keep in protocol-agnostic code. I solved this problem by introducing a new function pointer in the Curl_handler struct called domore_getsock() which is only called during the DOMORE state for protocols that set that pointer. The new ftp.c:ftp_domore_getsock() function now returns fdset info about the control connection's command/response handling while such a state is in use, and goes over to waiting for a writable second connection first once the commands are done. The original problem could be seen by running test 525 and checking the time stamps in the FTP server log. I can verify that this fix at least fixes this problem.

2011-09-03fix a bunch of MSVC compiler warningsYang Tse
2011-08-19tcpconnect: follow-up commit after b998d95bDaniel Stenberg
As I modified conn->bits.tcpconnect to become an array that holds one bool for each potential connection all uses of that struct field must index it correctly.

2011-06-21[pop3] remove extra space in LIST commandOri Avtalion
Some servers, e.g. mail.bezeqint.net:110, consider it a syntax error
2011-05-05RTSP: convert protocol-specific checks to genericDaniel Stenberg
Add a 'readwrite' function to the protocol handler struct and use that for the extra readwrite functionality RTSP needs.
2011-05-05SSL: check for SSL, not specific protocolsDaniel Stenberg
Code cleanup to check less for protocols and more for the specific relevant feature. Like if SSL is required.
2011-04-27whitespace cleanup: no space first in conditionalsDaniel Stenberg
"if(a)" is our style, not "if( a )"
2011-04-27source cleanup: unify look, style and indent levelsDaniel Stenberg
By the use of a the new lib/checksrc.pl script that checks that our basic source style rules are followed.
2011-04-21Fix a couple of spelling errors in lib/Fabian Keil
Found with codespell.
2011-04-20CURL_DOES_CONVERSIONS: cleanupDaniel Stenberg
Massively reduce #ifdefs all over (23 #ifdef lines less so far) Moved conversion-specific code to non-ascii.c
2011-04-05[pop3 starttls] PASS command was not sent after upgrade to TLS.Ben Noordhuis
2011-04-05[pop3 starttls] the command to send is STLS, not STARTTLS.Ben Noordhuis
2011-04-04http-proxy: move proxy code to http_proxy.cDaniel Stenberg
The new http_proxy.* files now host HTTP proxy specific code (500+ lines moved out from http.c), and as a consequence there is a macro introduced for the Curl_proxyCONNECT() function so that code can use it without actually supporting proxy (or HTTP) in builds.
2011-03-19pop3: add state name in debug arrayDaniel Stenberg
We have an array with the state names only built and used when built debug enabled and this need to list all the states from the .h
2011-03-18pop3: use Curl_safefree() to allow torture tests to succeedDan Fandrich
2011-03-18pop3: remove unused variableDaniel Stenberg
2011-03-17Added support for LISTing a single POP3 messageDan Fandrich
Added tests for a number of POP3 LIST operations, including one that shows a curl problem when listing no messages, so is disabled.
2011-03-17pop3: fixed memory leak in an error retrieval caseDan Fandrich
2011-03-15protocol handler cleanup: SSL awarenessDaniel Stenberg
As a follow-up to commit 8831000bc0: don't assume that the SSL powered protocol alternatives are available.
2011-03-14protocols: use CURLPROTO_ internallyDaniel Stenberg
The PROT_* set of internal defines for the protocols is no longer used. We now use the same bits internally as we have defined in the public header using the CURLPROTO_ prefix. This is for simplicity and because the PROT_* prefix was already used duplicated internally for a set of KRB4 values. The PROTOPT_* defines were moved up to just below the struct definition within which they are used.
