Change Hachoir can't support PY2 so backport their PY3 to prevent a need for system dependant external binaries like mediainfo. Backported 400 revisions from rev 1de4961-8897c5b (2018-2014). Move core/benchmark, core/cmd_line, core/memory, core/profiler and core/timeout to core/optional/* Remove metadata/qt* PORT: Version 2.0a3 (inline with 3.0a3 @ f80c7d5). Basic Support for XMP Packets. tga: improvements to adhere more closely to the spec. pdf: slightly improved parsing. rar: fix TypeError on unknown block types. Add MacRoman win32 codepage. tiff/exif: support SubIFDs and tiled images. Add method to export metadata in dictionary. mpeg_video: don't attempt to parse Stream past length. mpeg_video: parse ESCR correctly, add SCR value. Change centralise CustomFragments. field: don't set parser class if class is None, to enable autodetect. field: add value/display for CustomFragment. parser: inline warning to enable tracebacks in debug mode. Fix empty bytestrings in makePrintable. Fix contentSize in jpeg.py to account for image_data blocks. Fix the ELF parser. Enhance the AR archive parser. elf parser: fix wrong wrong fields order in parsing little endian section flags. elf parser: add s390 as a machine type. Flesh out mp4 parser. PORT: Version 2.0a1 (inline with 3.0a1). Major refactoring and PEP8. Fix ResourceWarning warnings on files. Add a close() method and support for the context manager protocol ("with obj: ...") to parsers, input and output streams. metadata: get comment from ZIP. Support for InputIOStream.read(0). Fix sizeGe when size is None. Remove unused new_seekable_field_set file. Remove parser Mapsforge .map. Remove parser Parallel Realities Starfighter .pak files. sevenzip: fix for newer archives. java: update access flags and modifiers for Java 1.7 and update description text for most recent Java. Support ustar prefix field in tar archives. Remove file_system* parsers. Remove misc parsers 3d0, 3ds, gnome_keyring, msoffice*, mstask, ole*, word*. Remove program parsers macho, nds, prc. Support non-8bit Character subclasses. Python parser supports Python 3.7. Enhance mpeg_ts parser to support MTS/M2TS. Support for creation date in tiff. Change don't hardcode errno constant. PORT: 1.9.1 Internal Only: The following are legacy reference to upstream commit messages. Relevant changes up to b0a115f8. Use integer division. Replace HACHOIR_ERRORS with Exception. Fix metadata.Data: make it sortable. Import fixes from e7de492. PORT: Version 2.0a1 (inline with 3.0a1 @ e9f8fad). Replace hachoir.core.field with hachoir.field Replace hachoir.core.stream with hachoir.stream Remove the compatibility module for PY1.5 to PY2.5. metadata: support TIFF picture. metadata: fix string normalization. metadata: fix datetime regex Fix hachoir bug #57. FileFromInputStream: fix comparison between None and an int. InputIOStream: open the file in binary mode.
