Subject: [PATCH] comics: Port to using libarchive for unarchiving
|
|||
|
|
|||
|
v8:
|
|||
|
- Fix double-free in error path when decompressing images
|
|||
|
|
|||
|
v7:
|
|||
|
- Bump buffer size in ev-archive, good performance increase for
|
|||
|
local files
|
|||
|
|
|||
|
v6:
|
|||
|
- Fix 2 pretty big memory leaks
|
|||
|
- Remove unneeded archive_read_data_skip() calls
|
|||
|
- Optimise the "no rotation" case (could also be done for gnome-3-24)
|
|||
|
- Use render_pixbuf_size_prepared_cb()
|
|||
|
- Add debug to "next header" archive calls
|
|||
|
|
|||
|
v5:
|
|||
|
- Remove unused members of ComicsDocument struct
|
|||
|
- Split archive handling into an EvArchive object
|
|||
|
- Fix copy/paste error in configure.ac
|
|||
|
|
|||
|
v4:
|
|||
|
- Fix crash caused by a bug in comics_document_list()
|
|||
|
(the array was not NULL terminated)
|
|||
|
- Remove duplicate "!cb_files" check
|
|||
|
- Use "size-prepared" instead of "area-prepared" to get the doc size
|
|||
|
- Fix link to libarchive bug in code, not working yet :/
|
|||
|
|
|||
|
v3:
|
|||
|
- Rebase against latest evince, making sure to bring back:
|
|||
|
- Use Unicode in translatable strings
|
|||
|
- Sort pages in natural order
|
|||
|
- Fix mime-type comparisons
|
|||
|
- https://github.com/libarchive/libarchive/issues/373 looks
|
|||
|
like it's fixed!
|
|||
|
|
|||
|
v2:
|
|||
|
- Rebase against latest evince
|
|||
|
- Update libarchive bug URL
|
|||
|
|
|||
|
https://bugzilla.gnome.org/show_bug.cgi?id=720742
