Teach tar to auto-detect gzip-compressed archives for list and extract
operations while keeping archive creation explicit via -z/--gzip.
Route archive I/O through a shared compression helper that supports plain,
gzip, and zstd streams. This keeps the existing --zstd behavior while adding
gzip sniffing on reads and gzip encoding on writes when requested.
Add integration tests covering gzip create, list, extract, explicit -z on
extract/list, stdio round-tripping, invalid gzip input, and continued zstd
create/list/extract behavior.
* tar: add explicit zstd compression support
Add an explicit --zstd flag for create, list, and extract so
.tar.zst archives work end to end.
Keep the scope narrow by requiring the flag instead of trying to
autodetect compression. Add CLI coverage and end-to-end tests for
creating, listing, and extracting zstd-compressed archives.
* tar: update benchmarks for compression mode
Pass CompressionMode::None from the existing tar benchmarks after the archive operation helpers gained explicit compression arguments.
Keep the operation helpers and CompressionMode public so the external benchmark target can continue importing them through the uu_tar library.
When the archive path is "-", read archives from stdin for list and
extract, and write archive data to stdout for create.
Route create status output to stderr when writing the archive to
stdout so verbose output does not corrupt the stream. Add CLI tests
for create-to-stdout, list-from-stdin, extract-from-stdin, and the
stderr routing cases.
Added support for -P and --absolute-names flags to preserve absolute
paths when creating archives, matching GNU tar behavior.
* CLI: Added -P / --absolute-names options to uu_app.
* Operations: Configured tar::Builder to preserve absolute paths
based on the new flag.
* Normalization: Updated normalize_path to skip stripping root
and prefix components when absolute paths are allowed.
* Tests: Added integration tests for path preservation and trimming
during archive creation and extraction.
Implement the list operation. Non-verbose (-t) prints one entry path
per line. Verbose (-tv) prints permissions, owner/group, size,
modification time, and path — matching GNU tar's ls-l style output.
Adds conflict group so -c, -x, and -t are mutually exclusive.
Pulls in chrono for timestamp formatting in verbose output. chrono is
already in the workspace dependency set and will also be needed for
date parsing when --newer=DATE is implemented.
Point uucore/uutests at the coreutils git repo while we're iterating
quickly on basic functionality.
Support traditional key syntax (for example `tar cvf archive.tar file`)
by rewriting a leading key operand into clap-compatible short options
before argument parsing.
- detect valid keystrings in argv[1]
- expand key letters into `-<opt>` arguments
- consume operands for `f` and `b` in key order
- forward `-b` (currently unsupported) so key/dash forms fail consistently
- update usage text to document key syntax
- add unit tests for key detection/expansion
- add integration tests for create/extract parity and `-b` failure parity

* Implement minimal create and extract operations
Adds basic tar archive functionality using tar-rs library with proper
error handling infrastructure.
Core Implementation:
- TarError enum implementing UError for uucore integration
- Extract operation (-x) for unpacking tar archives
- Create operation (-c) for creating tar archives from files/directories
- Verbose mode (-v) for both operations
- Proper CLI argument parsing with -f flag for archive file
Error Handling:
- Comprehensive error types (IoError, InvalidArchive, FileNotFound, etc.)
- Proper error conversion from io::Error
- UError trait implementation for exit code handling
This provides the minimal foundation for tar functionality. Both create
and extract are included together since they depend on each other for
testing purposes.
Includes 18 tests total:
- 8 integration tests (CLI basics, create/extract operations, error handling)
- 10 unit tests (CLI flag parsing, error type handling)
- Unit tests organized in src/uu/tar/tests/ separate from implementation
Note: Run `cargo test --workspace` to execute all tests including unit tests.
* Re-add cognitive complexity warning suppression for uu_app function
* Sort out tar/tarapp conflict
Rename package from "tar" to "tarapp" in Cargo.toml and update
dependencies to use workspace for tar.
* fix(errors): improve error handling and exit codes for tar operations
- Updated error messages for file not found and permission denied cases.
- Fix exit codes for various TarError types to conform to standard.
- Refactored extract_archive to use new error handling.
- Adjusted tests to reflect updated exit codes.
* Update for error changes (fixes cargo test --all)
* Use arg! macro and comment out rather than remove the unimplemented items.
* fix(create): Remove duplicate message for missing files in create_archive
