- Support adding directory contents at the top level of the
ZipStreamby specifying an arcname of/ - Fix issue where leading path separators could cause an incorrect size to be calculated.
- Fix issue where it was possible to add paths with arcnames that didn't match the path contents (file ending with "/", directory not ending with "/")
- Add the ability to get information on added files using
ZipStream.info_list. This function replacesZipStream.get_infowhich would only provide information on files that had already been streamed. - Deprecate
ZipStream.get_info. It will continue to work until the next major version but will now emit a warning when used. - Reduce memory usage for sized
ZipStreamobjects by updating the final size of the stream as files are added instead of storing the required information so the size could be calculated later.
- Add the ability to provide a custom "walk" function to
ZipStream.add_pathfor more control over how directories are walked. - Change the exception raised when trying to add a file that doesn't exist from a
ValueErrorto a more appropriateFileNotFoundError. - Optimize the number of
os.statcalls required to add a file. - Fix issue where adding data with an arcname that contained a null byte would lead to an incorrect size being calculated.
- When
ZipStream.addis provided a size alongside an iterable, the size will now be used to determine if Zip64 extensions are needed.
- Add
ZipStream.mkdirmethod to make an empty directory inside the stream. - Fix an issue where
ZipStream.get_infowould return incorrect values forcompress_levelin cases where the compression level was specified, but had no effect (ie. when usingZIP_STORED/ZIP_LZMA). - Fix an edge case where top-level paths like
/could be added with an empty arcname. - Improve error messages for adding data as a directory and adding nonexistent paths.
- The expected size of data added to a
ZipStreamis now validated as it's generated. For unsizedZipStreams a mismatch in expected vs. actual size emits a warning, for sizedZipStreams aRuntimeErroris raised. - For sized
ZipStreams, add the option to provide the total size of an iterable when adding it. When the size is provided, the iterable will no longer have to immediately be read into memory to compute it.
- Fix issue where adding data via an iterable to an unsized
ZipStreamwouldn't fully implement Zip64 extensions. This caused some versions of7zto emit warnings (but still properly extract the data).
- Fix issue where adding files with multibyte characters in the filename would lead to an incorrect zip size being calculated.
- Fix issue where directly adding an empty folder would give it the wrong name in the archive and lead to an incorrect zip size being calculated.
- Fix documentation issue caused by the import shuffling in v1.3.1
- Set external attributes (permissions, directory flag, etc) on data added to the
ZipStreamviaadd()
- Allow importing functionality from
zipstream.ngas well aszipstreamto avoid namespace collisions with other projects that provide azipstreammodule.
- Add a
last_modifiedproperty toZipStreamobjects that returns adatetimeof the most recent modified date of all the files in the stream.
- Fix issue where adding empty directories would lead to an incorrect zip size being calculated.
- Fix issue where asking for the
ZipStream's size multiple times while adding data wouldn't properly check if Zip64 extensions were being used, causing an incorrect size to be calculated.
- Add a
sizedproperty toZipStreamobjects that checks if the size can be calculated for it - Change
ZipStream.from_pathto generate a sizedZipStreamif no compression is used
- Add support for Python 3.5 and 3.6
- Initial version
