Merge pull request #11027 from schellingb/archive_cleanup_1b 
Use MMAP again for ZIP loading/parsing
 2020-07-16 03:28:54 +02:00
Bernhard Schelling
b03cdbd0da First set of cleanups to archive handling (Rev B) 
- Don't read the entire archive file into memory on systems without HAVE_MMAP
- Support ZIP files between 2GB ~ 4GB on 32bit architectures
- Remove zip exclusive members from `file_archive_transfer`
- Add `zip_context_t` for zip like the already existing `sevenzip_context_t`
- Unify cleanups of zip and 7z in `file_archive_file_backend::archive_parse_file_free`
- Handle some sizes and offsets as int64_t (preparation for future Zip64 support)
- Handle ZIP compression methods in `zlib_stream_decompress_data_to_file_init` not in `file_archive_perform_mode`
- Return progress of 7z iterating with `file_archive_parse_file_progress`
- Uses MMAP where available, for files up to 256MB

de111ea903 Should fix some zip archives potentially not working on Linux; the 
stream member of zlib was being set to random memory, so it was
attempted
 to be freed on line 73 of trans_stream_zlib.c

6904101c44 Clean up trailing whitespace 
== DETAILS

Really simple code cleanup, because my editor flags trailing whitespaces
and it's pretty annoying.
