Upcoming Changes

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.
