2020-03-07mime: fix the binary encoder to handle large data properlyPatrick Monnerat
New test 666 checks this is effective. As upload buffer size is significant in this kind of tests, shorten it in similar test 652. Fixes #4860 Closes #4833 Reported-by: RuurdBeerstra on github
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

2019-05-12build: fix "clarify calculation precedence" warningsMarcel Raad
Codacy/CppCheck warns about this. Consistently use parentheses as we already do in some places to silence the warning. Closes https://github.com/curl/curl/pull/3866
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

Found via `codespell` Closes #2389
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

2017-09-05mime: 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.

and some minor whitespace fixes
2017-09-03mime: use size_t instead of ssize_t in public API interface.Patrick Monnerat
To support telling a string is nul-terminated, symbol CURL_ZERO_TERMINATED has been introduced. Documentation updated accordingly. symbols in versions updated. Added form API symbols deprecation info.
2017-09-03mime: remove support "-" stdin pseudo-file name in curl_mime_filedata().Patrick Monnerat
This feature is badly supported in Windows: as a replacement, a caller has to use curl_mime_data_cb() with fread, fseek and possibly fclose callbacks to process opened files. The cli tool and documentation are updated accordingly. The feature is however kept internally for form API compatibility, with the known caveats it always had. As a side effect, stdin size is not determined by the cli tool even if possible and this results in a chunked transfer encoding. Test 173 is updated accordingly.
2017-09-03mime: fix some implicit curl_off_t --> size_t conversion warnings.Patrick Monnerat
