2020-03-07mime: do not perform more than one read in a rowPatrick Monnerat
Input buffer filling may delay the data sending if data reads are slow. To overcome this problem, file and callback data reads do not accumulate in buffer anymore. All other data (memory data and mime framing) are considered as fast and still concatenated in buffer. As this may highly impact performance in terms of data overhead, an early end of part data check is added to spare a read call. When encoding a part's data, an encoder may require more bytes than made available by a single read. In this case, the above rule does not apply and reads are performed until the encoder is able to deliver some data. Tests 643, 644, 645, 650 and 654 have been adapted to the output data changes, with test data size reduced to avoid the boredom of long lists of 1-byte chunks in verification data. New test 667 checks mimepost using single-byte read callback with encoder. New test 668 checks the end of part data early detection. Fixes #4826 Reported-by: MrdUkk on github
2020-03-07mime: latch last read callback status.Patrick Monnerat
In case a read callback returns a status (pause, abort, eof, error) instead of a byte count, drain the bytes read so far but remember this status for further processing. Takes care of not losing data when pausing, and properly resume a paused mime structure when requested. New tests 670-673 check unpausing cases, with easy or multi interface and mime or form api. Fixes #4813 Reported-by: MrdUkk on github

2019-09-18mime: when disabled, avoid C99 macroDaniel Stenberg
Closes #4368
2019-05-13mime: acknowledge CURL_DISABLE_MIMEDaniel Stenberg
2019-03-22lib: Fix typos in commentsDaniel Gustafsson
2019-02-12mime: put the boundary buffer into the curl_mime structDaniel Stenberg
... instead of allocating it separately and point to it. It is fixed-size and always used for each part. Closes #3561
2018-02-05formdata: use the mime-content type functionDaniel Stenberg
Reduce code duplication by making Curl_mime_contenttype available and used by the formdata function. This also makes the formdata function recognize a set of more file extensions by default. PR #2280 brought this to my attention. Closes #2282
2018-01-14mime: clone mime tree upon easy handle duplication.Patrick Monnerat
A mime tree attached to an easy handle using CURLOPT_MIMEPOST is strongly bound to the handle: there is a pointer to the easy handle in each item of the mime tree and following the parent pointer list of mime items ends in a dummy part stored within the handle. Because of this binding, a mime tree cannot be shared between different easy handles, thus it needs to be cloned upon easy handle duplication. There is no way for the caller to get the duplicated mime tree handle: it is then set to be automatically destroyed upon freeing the new easy handle. New test 654 checks proper mime structure duplication/release. Add a warning note in curl_mime_data_cb() documentation about sharing user data between duplicated handles. Closes #2235
2017-10-08mime: improve unbinding top multipart from easy handle.Patrick Monnerat
Also avoid dangling pointers in referencing parts.
2017-09-22form/mime: field names are not allowed to contain zero-valued bytes.Patrick Monnerat
Also suppress length argument of curl_mime_name() (names are always zero-terminated).
2017-09-06mime: drop internal FILE * support.Patrick Monnerat
- The part kind MIMEKIND_FILE and associated code are suppressed. - Seek data origin offset not used anymore: suppressed. - MIMEKIND_NAMEDFILE renamed MIMEKIND_FILE; associated fields/functions renamed accordingly. - Curl_getformdata() processes stdin via a callback.
2017-09-05mime: replace 'struct Curl_mimepart' by 'curl_mimepart' in encoder code.Patrick Monnerat
mime_state is now a typedef.
2017-09-05mime: implement encoders.Patrick Monnerat
curl_mime_encoder() is operational and documented. curl tool -F option is extended with ";encoder=". curl tool --libcurl option generates calls to curl_mime_encoder(). New encoder tests 648 & 649. Test 1404 extended with an encoder specification.
2017-09-05mime: unified to use the typedef'd mime structs everywhereDaniel Stenberg
... and slightly edited to follow our code style better.
2017-09-02mime: new MIME API.Patrick Monnerat
Available in HTTP, SMTP and IMAP. Deprecates the FORM API. See CURLOPT_MIMEPOST. Lib code and associated documentation.
