Stacked Git 2.0.0-alpha.1

This is the first official alpha release of StGit 2.0, the Rust reimplementation of StGit.

The change notes below cover both this alpha.1 release as well as the untagged/unreleased alpha.0.

The biggest change from alpha.0 is the addition of shell completions and the stg completion support commands. Shell completions were rewritten from the ground-up, but are hopefully at least as capable as those that shipped with StGit 1.x.

[2.0.0-alpha.1] 2022-06-17

Removed

Added

• stg series gains the -i/--commit-id option to display patches' commit ids.
• stg series colorized output is modified. The main change is that patch descriptions are no longer yellow.
• stg version now displays copyright and license statements.
• stg version gains -s/--short flag to show shortened version info.
• The stgit.diff-opts configuration variable is now respected as it was in the Python implementation.
• stg completion command provides runtime support for shell completions.
• stg completion bash generates bash shell completion script.
• stg completion fish generates fish shell completion script.
• stg completion zsh outputs zsh shell completion script.
• stg completion list shows StGit commands and aliases and is used at completion-time by shell completion scripts.

Changed

• The -O/--diff-opts flag now allows both multiple space separated opts in one value as well as multiple occurrences of -O/--diff-opts on the same command line. This behavior is compatible with the Python implementation.
• stg series help output splits options into a few sections.
• Dependencies are updated to more recent versions in Cargo.lock.

Fixed

• stg edit --set-tree no longer causes the interactive editor to be implicitly invoked.
• Repair build for non-Linux unix targets (including MacOS) and Windows targets.
• Avoid case insensitive patch name collisions. On operating systems with case-insensitive paths, patch names that only differ by case lead to patch reference collisions. StGit now ensures that patch names are distinct under case insensitive comparisions.
• Add missing -t short option for --set-tree for stg edit.
• Add missing -k short option for --keep.

[2.0.0-alpha.0] 2022-05-17

Removed

• stg edit no longer accepts -O/--diff-opts. Custom diff options is in conflict with editable diffs since many (most?) diff options cause
  the diff to no long be applicable.
• stg files no longer accepts -O/--diff-opts. This option was of marginal value since it only had a possible side effect when --stat was being used.
• stg clone is removed (at least for the time being). Use git clone and stg init instead.
• stg mail is removed, but will be re-added or replaced prior to the 2.0.0 release.

Added

• stg new --refresh allows a new patch to be refreshed with changes in one step. The -i/--index, -F/--force, -s/--submodules, and --no-submodules options from stg refresh are also available to stg new.
• stg id now accepts the -b/--branch option.
• stg spill replaces stg refresh --spill.

Changed

• StGit aliases are now more like Git aliases. Normal aliases refer to StGit subcommands, but aliases prefixed with '!' are shell aliases that may run arbitrary commands. An example normal alias would be git config stgit.alias.list 'series --description --empty'. An example shell alias would be git config stgit.alias.st '!git status --short'.
• The --ack and --review options now optionally take a value. The --ack-by and --review-by options are deprecated.
• Commands such as stg goto, stg push, and stg pop now require full/correct patch names on the command line and no longer accept unambiguous patch name prefixes. When an inexact patch name is provided on the command line, the error message will now indicate similar valid patch names.
• stg branch output is now generally less verbose.
• stg branch --describe replaces stg branch --description. The --description subcommand remains supported as a hidden alias to --describe, but the description string must now be provided as its own argument; i.e. --description="description string" is no longer supported.
• stg branch --list now produces colorized output. The --color option or NO_COLOR environment variable may be used to affect this behavior.
• stg branch --rename now supports renaming regular git branches in addition to StGit-enabled branches.
• stg clean now uses -A and -U short options for --applied and --unapplied instead of -a and -u. This is done for consistency with stg series and stg show.
• stg import now only recognizes compressed patches by their file extension (.bz2 or .gz) and no longer attempts to decompress usin all known decompressors.
• stg import support for compressed input files is selectable at compile time using the import-compressed feature.
• stg import support for importing from a URL is selectable at compile time using the import-url feature.
• stg log now colorizes output by default. The --color option or NO_COLOR environment variable may be used to affect this behavior.
• stgit.new.verbose changed to stgit.edit.verbose and now affects edit behavior for edit, refresh, and squash along with new.
• stg new now accepts -e/--edit and -d/--diff instead of -v/--verbose
• stg pick now allows a mix of commits and patches to be picked whereas previously only a single commit xor multiple patches could be picked.
• stg pick now performs a single stack transaction for all the picked patches/commits instead of one transaction per pick.
• stg rebase --interactive the "squash" and "fixup" instructions may no longer be applied to the first patch in the instruction list. The stated semantics of both "squash" and "fixup" is that they squash the labeled patch with the preceding patch, which is not possible/valid when there is no preceding patch.
• stg refresh no longer has the --spill flag. Use stg spill instead.
• Updated colorized output for stg series.
• stg series now requires patch range arguments to be both in-order and contiguous. Constraining patch ranges in this manner ensures that the output from stg series is always a valid/correct view of a subset of the series.
• stg show diff can now be limited to certain paths by specifying path limits on the command line.
• stg show diff output respects the --color option.
• The new --signoff patch edit option supercedes the deprecated --sign and --sign-by options. --signoff without its optional value does the same thing as --sign, while --signoff=<value> does the same thing as --sign-by=<value>.
• stg squash now allows the full suite of patch edit options, including -d/--diff. Previously only a few message-related options were available.

Fixed

• stg branch --create inherits the current branch's remote branch configuration, if available. The Python implementation had an apparent bug that prevented inheriting the remote branch configuration when creating from the current branch.
