2026-08-16feat(php-shim): render human-facing timestamps in the local timezonensfisis
Split date() into date_utc() and date_local(), the latter resolving the system's local timezone through the tzfile crate ($TZ, then /etc/localtime, falling back to UTC when neither is readable). The timestamps Composer renders for humans -- the GitHub OAuth token note, the GitHub API rate limit reset time, the Perforce client spec fields and the "today" check of the show command -- now go through date_local(). PHP resolves its default timezone from the date.timezone ini setting, which Shirabe does not read, so date_default_timezone_get/set have no input left to model and are dropped from the shim and its callers. The resulting difference is recorded in docs/known-incompatibilities.md. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-15feat(cli): report Shirabe's own identity instead of Composer'snsfisis
The binary called itself Composer everywhere: the application name, the logo, --version, about, and every warning that talks about the running program. Prompts to file a bug also pointed at Composer's issue tracker. Add SHIRABE_VERSION and SHIRABE_RELEASE_DATE next to the Composer version constants and report those, naming the Composer version this port tracks alongside them. Composer::VERSION and getVersion() are untouched, so the composer platform package, composer-runtime-api and the HTTP User-Agent keep the value plugins and package repositories expect. build.rs stamps the release date with the UTC date of the HEAD commit, the way Composer's Compiler fills in @release_date@ when building the phar. It now also fails the build when git cannot be read, instead of letting COMPOSER_DEV_WARNING_TIME fall back to the tagged-release value and suppress the outdated-build warning forever. Messages about the Composer ecosystem keep their wording. Two of them are pinned by upstream installer fixtures (Rule's "cannot be modified by Composer" and SolverProblemsException's "you can run Composer with") and stay as they are so those fixtures can keep being used verbatim. The e2e list comparison against upstream Composer now skips the banner, which cannot match by design, and compares everything below it as before.

2026-08-11chore(php-shim): drop the ob_start()/ob_get_clean() portsnsfisis
Output buffering captures whatever the PHP interpreter would echo to stdout. The shim routes no output through a buffer, so these functions could never capture anything and stayed todo!(). Record the gap in docs/known-incompatibilities.md instead.
2026-08-11feat(signal): abort on SIGINT, SIGTERM and SIGHUP at checkpointsnsfisis
The SignalHandler port was a no-op stub, so all four of Composer's abort paths were dead code: nothing removed a half-created project, reverted composer.json, or cleaned up half-installed packages. Composer runs those handlers from pcntl callbacks, which a Rust signal handler cannot do -- it may touch nothing beyond atomics. SignalSubscription records the signal instead, and the abort runs from checkpoints on the normal call stack, where the clean-up can borrow the state it needs. That also resolves the closure-capture TODO(phase-c)s in RequireCommand and InstallationManager, and replaces exit_with_last_signal's exit(0) with the restore-and-re-raise Seld\Signal does. A subscription is live only inside the four abort regions, so elsewhere the signals keep their default disposition and kill the process at once. It is installed without SA_RESTART so a signal interrupts an interactive prompt rather than resuming the read. A signal reaches only the innermost subscription, reproducing SignalHandler's single-stack dispatch. Drop SignalRegistry, SignalableCommandInterface and the Application wiring for them: nothing in Composer reaches that path, and SignalHandler discards whatever they register. Signal handling from plugins and scripts is undefined behavior; see docs/dev/signals.md. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-10feat(xdebug): switch Xdebug off in the PHP workernsfisis
Composer restarts itself with Xdebug unloaded because Xdebug makes PHP several times slower. Xdebug is never loaded into this process, so what needs dealing with is the PHP worker: it is spawned with `-d xdebug.mode=off` and `XDEBUG_MODE=off` (Xdebug reads the environment variable first and lets it override every ini setting), which makes its module init return before it installs any executor, compile, error or opcode hook. Rewriting the ini files and re-executing, the way xdebug-handler does, would additionally cover Xdebug 2, which hooks unconditionally and has no equivalent setting. That is not worth its machinery here: Xdebug 2 caps out at PHP 7.4, while every PHP version Composer supports can run Xdebug 3. What remains of XdebugHandler is small enough to live beside the worker it governs, so its crate is gone and its callers inline it. isXdebugActive answers false without asking PHP whenever the worker is switched off, so a command that needs no PHP does not spawn one just for the Xdebug warning; diagnose reports what the worker measures instead, which still surfaces an Xdebug that ignores the setting. PlatformRepository has no unloaded extension to restore, since switching the mode off leaves it loaded. COMPOSER_ORIGINAL_INIS is neither written nor read: it exists so a restarted process can name the ini files it replaced, and IniHelper can report the worker's own. IniHelperTest injects through that variable, so none of its cases are ported. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

2026-07-04feat(config): use shirabe-branded default home/cache/data dirsnsfisis
Avoid colliding with an existing Composer installation on the same machine by defaulting COMPOSER_HOME/CACHE_DIR/DATA_DIR paths to shirabe/Shirabe instead of composer/Composer, while keeping the env var names, composer.json/lock, and vendor/composer/ unchanged for ecosystem compatibility.
2026-06-21refactor(json): eliminate json_last_error in favor of Resultnsfisis
json_encode/json_encode_ex now return anyhow::Result<String> instead of Option, so callers no longer need json_last_error() to get the failure reason. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
