# Changelog
|
|
|
|
## Upcoming Changes
|
|
|
|
## Version 1.7
|
|
|
|
Refactor the internal hash-map data structure.
|
|
|
|
Minor update to CMakeLists.txt.
|
|
|
|
## Version 1.6
|
|
|
|
Enforce "safe-links" on extraction by ensuring every extracted symlink actually
|
|
points to a file in the archive. Additionally any extracted symlinks that don't
|
|
point to a valid destination is removed. This "enforce safe-links on extract"
|
|
can be disabled with the "--no-safe-links" option.
|
|
|
|
Add "--preserve-symlinks" option that will verbatim store the symlinks' target.
|
|
Not recommended if symlinks are pointing to absolute paths, which will be
|
|
clobbered on extraction to a different directory unless if "--no-safe-links" is
|
|
specified on extraction.
|
|
|
|
## Version 1.5
|
|
|
|
Previous file-format-v1 implementation of "safe links" still created a symlink
|
|
if a relative or absolute link existed in the file. This version fixes this, and
|
|
prevents invalid symlinks from being created. (This check is only done if the
|
|
bit-flag is set in the file as mentioned in the file-format spec for v1 files.)
|
|
|
|
## Version 1.4
|
|
|
|
Do "safe links" behavior by default: symlinks pointing to outside of archived
|
|
files (or invalid symlinks) should not be included in the archive, unless if the
|
|
option "--no-safe-links" is specified. This is supported in both v0 and v1 file
|
|
formats.
|
|
|
|
## Version 1.3
|
|
|
|
Prevent `simplearchiver` from busy-waiting during non-blocking IO by sleeping
|
|
in "EWOULDBLOCK" conditions. This results in less consumed cpu time by the
|
|
process, especially during compression.
|
|
|
|
## Version 1.2
|
|
|
|
Proper handling of Ctrl+C (SIGINT). This prevents temporary files from
|
|
persisting by doing a proper cleanup before stopping the program.
|
|
|
|
## Version 1.1
|
|
|
|
More robust handling of de/compression process (handling SIGPIPE).
|
|
|
|
By default files are now pre-sorted by size before placed into chunks.
|
|
Add option to NOT pre-sort files by size.
|
|
|
|
## Version 1.0
|
|
|
|
First release.
|
|
|
|
Features:
|
|
|
|
- Can specify any command as de/compressor when archiving.
|
|
- The commands must accept file data in stdin and output processed data to
|
|
stdout.
|
|
- Can specify any command as decompressor when extracting to override the
|
|
simple-archive's stored decompressor.
|
|
- Archives/compresses into chunks to reduce overhead by compressing per chunk
|
|
instead of per file.
|
|
- Chunk size can be tweaked by a parameter setting.
|
|
- Can archive without de/compressor to be compressed separately.
|
|
- Supports pre-version-1 simple archiver file format (version 0).
|
|
- Archives regular files and symlinks.
|
|
- Keeps track of files and symlink permissions.
|
|
- Keeps track of file UID and GID (only set if extracting as root).
|
|
- Can be set to ignore absolute paths for symlinks by parameter setting.
