This project follows Semantic Versioning (major.minor.patch
), with the
exception that behavior changes are allowed in minor releases as long as the
change corrects behavior to match documentation, specification or
expectation. In other words: Bugfixes do not count as backward incompatible
changes, even if they technically change behavior from incorrect to correct
and may break applications that rely on incorrect or undefined behavior.
This release improves error handling, fixes several parser edge-cases and adds new functionality. API changes are backwards compatible.
- feat: Split up MultipartError` into more specific exceptions and add HTTP status code hints. All exceptions are subclasses of MultipartError.
- feat: New parse_form_data(ignore_errors) parameter to throw exceptions in non-strict mode, or suppress exceptions in strict mode. Default behavior does not change (throw in strict-mode, ignore in non-strict mode).
- feat: New is_form_request(environ) helper.
- feat: New specialized content_disposition_[un]quote functions.
- feat: parse_options_header() can now use different unquote functions. The default does not change.
- fix: parse_form_data() no longer checks the request method and the new is_form_request function also ignores it. All methods can carry parse-able form data, including unknown methods. The only reliable way is to check the Content-Type header, which both functions do.
- fix: First boundary not detected if separated by chunk border.
- fix: Allow CRLF in front of first boundary, even in strict mode.
- fix: Fail fast if first boundary is broken or part of the preamble.
- fix: Fail if stream ends without finding any boundary at all.
- fix: Use modern WHATWG quoting rules for field names and filenames (#60). Legacy quoting is still supported as a fallback.
This release could have been a patch release, but some of the fixes include change in behavior to match documentation or specification. None of them should be a surprise or have an impact on real-world clients, though. Existing apps should be able to upgrade without issues.
- fix: Fail faster on input with invalid line breaks (#55)
- fix: Allow empty segment names (#56)
- fix: Avoid ResourceWarning when using parse_form_data (#57)
- fix: MultipartPart now always has a sensible content type.
- fix: Actually check parser state on context manager exit.
- fix: Honor Content-Length header, if present.
- perf: Reduce overhead for small segments (-21%)
- perf: Reduce write overhead for large uploads (-2%)
This release introduces a completely new, fast, non-blocking PushMultipartParser
parser, which now serves as the basis for all other parsers.
- feat: new
PushMultipartParser
parser. - change: Parser is stricter by default and now rejects clearly broken input. This should not affect data sent by actual browsers or HTTP clients, but may break some artificial unit tests. * Fail on invalid line-breaks in headers or around boundaries. * Fail on invalid header names.
- change: Default charset for segment headers and text fields changed to
utf8
, as recommended by W3C HTTP. - change: Default disk and memory limits for
MultipartParser
increased, but multiple other limits were introduced to allow finer control. Check if the new defaults still fit your needs. - change: Several undocumented APIs were deprecated or removed, some of which were not strictly private but should only be used by the parser itself, not by applications.
This release dropped support for Python versions below 3.6
. Stay on multipart-0.1
if you need Python 2.5+ support.

- build: Add python-requires directive, indicating Python 3.5 or later is required and preventing older Pythons from attempting to download this version (#32)
- fix: Add official support for Python 3.10-3.12 (#38, #48)
- fix: Default value of
copy_file
should be2 ** 16
, not2 * 16
(#41) - docs: Update URL for Bottle (#42)
- fix: Consistently decode non-utf8 URL-encoded form-data
- fix: Import MutableMapping from collections.abc (#23)
