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git cannot be read, instead of letting COMPOSER_DEV_WARNING_TIME fall back to the tagged-release value and suppress the outdated-build warning forever.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.

2026-08-09refactor(pcre): extract composer/pcre into the shirabe-pcre cratensfisis
Move `Composer\Pcre` out of shirabe-external-packages and into its own crate, so the path is `shirabe_pcre::preg::Preg` instead of `shirabe_external_packages::composer::pcre::preg::Preg`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-09fix(exception): carry PHP's $previous through the ported throw sitesnsfisis
Composer hands the exception it caught to the one it throws in its place, so `getPrevious()` reaches the cause and Application's renderer prints the whole chain. Every ported site dropped it, because the flat exception structs had nowhere to put one. `AnyThrowable::into_previous` turns the caught error into that argument, and the 13 sites now pass it. `getCode()` came along for the ride at the four sites that derive the new exception's code from the caught one (PharArchiver, ArrayLoader x2), and ComposerRepository's message now names the caught exception's class instead of the literal "Exception". GitHubDriver::attemptCloneFallback took the previous exception's message and appended it to its own, which no `\RuntimeException('Fallback to git driver disabled')` in Composer ever says; it now chains it instead. Git::syncMirror restores what PHP's `finally` does to an exception in flight: the `git remote set-url` that scrubs credentials back out of the URL runs in a `finally`, and when it fails PHP propagates *its* exception over the one already leaving, chaining the displaced one as previous. The port discarded the finally's result, so a failure to scrub the URL was reported as a successful mirror sync. `AnyThrowable::set_previous` models the engine-level chaining.

2026-08-08feat(php-shim): give ported exceptions PHP's class hierarchynsfisis
Ported exceptions were flat structs reached with `downcast_ref`, so Composer's `catch (\RuntimeException $e)` only matched the exact leaf type and `get_class($e)` had nothing to report. Each exception now embeds an instance of the class it extends and travels inside an `AnyThrowable`; `Catch::catch`/`catch_mut` walk that chain, and `PhpClass::php_class_name` yields the PHP FQCN. Dropping the `std::error::Error` impls from the exception types leaves `AnyThrowable` as the only route into an `anyhow::Error`, so the walk cannot be bypassed. A `no_exception_downcast` linter catches the `downcast::<X>()` calls that would now silently answer `None`. Three sites change behavior as a result: the `TransportException` exit-code override reaches `MaxFileSizeExceededException`, the `catch (\LogicException)` in findSimilar() reaches its subclasses, and rendered exception titles carry the real class name rather than a guess. `get_class_err()` is no longer a `todo!()`, which re-enables FilesystemRepositoryTest::testCorruptedRepositoryFile.

2026-08-08refactor(semver): replace Constraint's OP_*/STR_OP_* with CmpOpnsfisis
PHP's version_compare takes its operator as a string, so the shim's port did too, and Constraint carried two families of operator constants plus translation tables to convert between the string form and its own int codes. Five copies of those tables had accumulated across Constraint, CompilingMatcher and the plugin value bridge. version_compare now takes a CmpOp, which makes an invalid operator unrepresentable and removes the tables' reason to exist. Constraint stores a CmpOp and keeps only the string parsing its constructor needs; getOperator, compile and CompilingMatcher::match speak CmpOp as well. PHP's OP_* numbering stays observable: a plugin reads the raw integer off the Constraint object over RPC, so get_operator_constant and its new inverse hold that 0..5 mapping.

2026-08-07refactor: merge split inherent impl blocks into one per typensfisis
Enable clippy::multiple_inherent_impl and fix the 21 sites it reports. Types whose inherent methods were spread across two or three impl blocks now keep them in a single block; only the impl headers move, no method bodies change. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-06chore: drop @param/@return tags that only restate Rust typesnsfisis
The ported docblocks copied @param and @return straight from the PHP source. When such a tag carries nothing but a type and an argument name, the Rust signature already states it, so the line is noise. Tags whose text adds prose beyond the type are kept.

2026-08-04fix(package): keep list-shaped license arrays in ValidatingArrayLoadernsfisis
PHP's `(array)` cast passes an array through unchanged, but the port only matched the map shape and wrapped a JSON list (e.g. ["MIT"]) as a single license value, which then failed the is-string check and was silently dropped from composer.lock / installed.json with a bogus warning. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
2026-08-02fix(repository): resolve remaining late-binding hazards from the auditnsfisis
Three fixes for the ComposerRepository/FilesystemRepository/PlatformRepository hazards where inner-composition delegation skipped PHP's late-bound virtual dispatch: - ComposerRepository::has_package now builds its packageMap through the late-bound getPackages() equivalent, so lazy-providers repos surface the LogicException and available-packages repos load their package list, as in PHP, instead of silently answering false from the raw array. - RepositoryInterface::get_repo_name returns anyhow::Result<String>: PHP's getRepoName() counts through the late-bound initialize(), which is fallible in file-reading subclasses. FilesystemRepository and PackageRepository now run that initialization instead of freezing the inner array repository to an empty state (which also made a later write() truncate installed.json). Supporting changes keep the initialization chain callable from &self: JsonFile::read takes &self (indent moved into a RefCell), FilesystemRepository dev_mode became a Cell, and WritableArrayRepository dev_package_names a RefCell. - PlatformRepository::new routes constructor packages through its own add_package so the override handling and full platform initialization run as they do via PHP's parent constructor; the inner find_package/add_package delegations inside add_package (and ComposerRepository::add_package) gained the same is_initialized guard, since the constructor path would otherwise freeze the repository. Same defect class as 7db937af, 97b5211a and 3e367f78. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

2026-07-20fix(php-shim): use PhpMixed::to_bool() for PHP truthy castsnsfisis
Several call sites coerced PhpMixed to bool via `.as_bool()` (which only matches a literal Bool variant) where the corresponding PHP code does a plain `(bool)` cast or truthy check (isset()/array_key_exists() + implicit bool conversion). This silently dropped truthy non-bool values (e.g. String("true"), String("1"), Int(1)) to their unwrap_or default instead of PHP's actual truthy result. Switched these sites to PhpMixed::to_bool(), which implements PHP's full truthy-cast rules.
2026-07-20fix(validating-array-loader): un-ignore test_fund_command by fixing empty checknsfisis
validate_array judged emptiness via as_array(), which only matches PhpMixed::Array, so a non-empty PhpMixed::List (e.g. a funding array) was misjudged as empty and dropped, diverging from PHP's !count() check. Match both Array and List. The stale ignore reason on test_fund_command no longer applies: init_temp_composer injects packagist:false so no network is reached, and the downloader stack is reqwest-based (no curl shim todo!()).

2026-07-19fix(root-package-loader): un-ignore 4 tests by fixing stability-flag isset() ↵nsfisis
port extract_stability_flags ported PHP's `isset($stabilityFlags[$name]) && $stabilityFlags[$name] > $stability` as `unwrap_or(i64::MAX) > stability`, so the check always short-circuited to "already more unstable" and no flag (e.g. from an explicit `*@dev` requirement) was ever recorded. Fixed using Option::is_some_and, a direct translation of PHP's isset() && ... check. Also fixes tests/common/test_case.rs's shared installation_manager() helper, which built a real InstallationManager::new instead of the __new_mock constructor (mirroring PHP's FactoryMock::createInstallationManager()), so it always had zero installers registered and wrote install-path: null into fixture installed.json files. Un-ignores test_reinstall_command, test_locally_modified_packages_from_source/ _from_dist, and test_package_still_present_error_when_no_install_flag_used — the first three were already passing (their #[ignore] reasons were stale), the last is fixed by the test_case.rs change above. Updates the #[ignore] reasons on installer_test.rs's three fixture-driven integration tests to reflect their current state: the install pipeline now runs end-to-end, but the ~189-fixture installer/ set still hits several independent, unrelated bugs/gaps that need case-by-case triage rather than a single fix.

2026-07-18perf(regex): eliminate per-call clone overhead in preg_* dispatchnsfisis
regex::Regex::clone() does not share the underlying meta engine's search-cache pool, so every fresh clone pays a ~10us warmup cost on its first use. Two changes together eliminate this across nearly all preg_* call sites: - A php_regex! macro resolves PHP-style patterns to a per-call-site &'static regex::Regex (via regex-macro's LazyLock), applied at the majority of call sites throughout the codebase. - Call sites still passing dynamic pattern strings go through PATTERN_CACHE, which now stores Arc<(Regex, bool)> and hands out Arc::clone()s instead of cloning the Regex itself. PregPattern::resolve() returns a ResolvedPattern enum (Arc or 'static reference) rather than an owned Regex, so neither path ever clones the Regex proper.

2026-07-11chore: use fully-qualified name for Rc/RefCellnsfisis
2026-07-05feat(validating-array-loader): implement LoaderInterfacensfisis
Convert errors/warnings/config to RefCell so load() can satisfy the trait's &self signature, matching upstream's `instanceof ValidatingArrayLoader` check in VcsRepository. This makes the InvalidPackageException downcast path in VcsRepository reachable for the first time instead of being permanently dead code.
2026-06-29chore(lint): ban bare `use anyhow::Result` and fully qualify itnsfisis
Add a no_banned_use linter that forbids importing anyhow::Result, and update all call sites to reference it via its fully-qualified path so it is never confused with std::result::Result. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-28refactor: add linternsfisis
2026-06-27test: port Composer tests unblocked by mockall, add seamsnsfisis
Port 11 categories of previously-ignored Composer tests now reachable with the mockall crate: DownloadManager, VCS/Perforce/File downloaders, VersionSelector, PlatformRepository, Auditor, installer/FilesystemRepository, RootPackageLoader, util auth/http, commands, and Cache. Extract test seams additively on concrete structs as *Interface traits (Runtime, HhvmDetector, VersionGuesser, RepositorySet, Perforce, BinaryInstaller) plus mock-field seams (Cache, Filesystem); consumers take trait objects. Mocks are defined locally in the test crates via mockall::mock!, since automock-generated mocks are cfg(test)-gated and invisible across the integration-test boundary. dataProviders are ported in full; tests blocked by unported shims stay #[ignore] with documented reasons rather than reduced or weakened. Fix product bugs surfaced by the ports: - util/github: use the exception code, not the HTTP status, for 401/403 - advisory: serialize empty audit maps as [] to match PHP json_encode - repository/filesystem and downloader/file: fix RefCell double-borrow panics Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-27refactor: fix compiler warnings and clippy warningsnsfisis
2026-06-26test: port 32 command/repository/downloader testsnsfisis
Add create_installed_json/create_composer_lock test helpers. Port command (8), repository path/forgejo/perforce/vcs (11), and fossil/hg/download_manager (13) tests. Fix production porting bugs: root_package_loader/forgejo_url/version_bumper regex delimiters, repository_manager create_repository_by_class, array_loader isset, licenses_command RefCell borrow; implement disk_free_space and touch2/touch3 via libc.

2026-06-26test: port 24 command/repository/package/util tests; add TlsHelpernsfisis
Port command (9), util gitlab/forgejo/tls (6), package (6), repository (3) tests. Implement TlsHelper. Fix porting bugs: config_command extra merge, RootAliasPackage setters, ValidatingArrayLoader isset, repository_factory name generation, forgejo exception code, version_parser error chaining.

2026-06-25feat(semver): hand-port constraint AND-split to drop look-around regexnsfisis
The PCRE delimiter `(?<!^|as|[=>< ,]) *(?<!-)[, ](?!-) *(?!,|as|$)` used to split AND-constraints relies on look-around, which the regex crate cannot compile (parse_constraints panicked). Reproduce its semantics in a hand-written `split_and_constraints` scanner shared by VersionParser and RootPackageLoader. Also model `method_exists` for the class-name form (shirabe runs no dumped Composer ClassLoader) and un-ignore the InstalledVersions tests, serialized via `#[serial]` since they share global static state.

composer::semver stubs Flatten shirabe-semver's modules into glob re-exports at the crate root and route all consumers through the short paths. Remove the duplicate composer::semver stubs from shirabe-external-packages in favor of the shirabe-semver types. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-24refactor(crates): split metadata-minifier and spdx-licenses into own cratesnsfisis

2026-06-21refactor(php-shim): split filter_var into per-filter functionsnsfisis
Replace the dispatch-on-constant filter_var() and filter_var_with_options() with dedicated filter_var_boolean/url/email/ip and filter_var_int_with_range, dropping the FILTER_VALIDATE_* constants and updating all call sites. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-20refactor(php-shim): drop Box wrapping from PhpMixed List/Arraynsfisis

2026-06-14refactor(pcre): drop Result from Preg method return typesnsfisis
The Preg methods panic on PCRE failure (per the file header rationale), so their anyhow::Result wrappers never carried an Err. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-14refactor(pcre): drop strict-groups Preg variantsnsfisis
Rust's type system already distinguishes participating from non-participating capture groups via Option, so the *StrictGroups methods add no safety here. Remove them and switch callers to the plain variants.
2026-06-12refactor(php-shim): replace literal sprintf calls with format!nsfisis
Convert every sprintf() call with a compile-time literal format string to format!, implementing Display for PhpMixed (delegating to php_to_string) so PhpMixed values render with PHP string semantics through {}. Also merge the format!-wrapped and conditional-literal dynamic sites into single format! calls. Genuinely runtime format strings (table styles, configurable error messages, command synopsis, progress-bar modifiers, regex-built messages) still go through sprintf. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-09feat(datetime): resolve datetime TODOsnsfisis
Introduce shim functions and constants, replacing the ad-hoc chrono format strings and parse helpers used as phase-b placeholders. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-08feat(phase-c): resolve PhpMixed-conversion phase-b TODOsnsfisis
Implement the foundational PhpMixed conversion infrastructure (From<bool|i64|f64|String>, order-sensitive PartialEq matching PHP ===) and resolve the category-G phase-b TODOs that depend on it: - Fix VCS driver cache paths that discarded parsed JSON or diverged on null caches (svn/forgejo/gitlab/git-bitbucket/github). - Wire up real conversions previously stubbed or dropped: suggests platform config, audit ignore-severities, composer_repository search and ProviderInfo, class_loader prefix/classmap merges, locker lock diff comparison, advisory JSON serialization, SPDX license fields. - Make GenericRule take a typed ReasonData; populate RULE_ROOT_REQUIRE with the constraint and convert PhpMixed at the call sites.
2026-06-08feat(phase-c): resolve reflection/downcast phase-b TODOsnsfisis
Resolve category F phase-b TODOs (class-string, instanceof, get_class, method_exists, __FILE__, Reflection API, downcast). - VcsRepository: dispatch drivers through a VcsDriverKind enum (instantiate/supports/php_class_name) and add constructors to the concrete VCS drivers - repository downcasts via RepositoryInterfaceHandle::downcast_rc and as_any (init/show commands, vcs ValidatingArrayLoader) - BaseCommand::is_self_update_command override replaces an instanceof - Factory::create narrows PartialComposer to ComposerHandle via as_full - InstalledVersions gains set_self_dir/set_installed_is_local_dir, replacing Reflection-based static property mutation - ClassLoader::as_array_iter ports the PHP (array) cast - drop the unnecessary __FILE__ phar branch in self-update application get_class(command) reclassified TODO(plugin); buffer_io StreamableInputInterface downcast and the ValidatingArrayLoader trait redesign left as tracked TODOs. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-06fix(json-loader): pass decoded config to loader instead of empty mapnsfisis
The Phase B stub discarded the decoded PhpMixed and handed an empty IndexMap to LoaderInterface::load, so nothing was actually loaded. Unbox PhpMixed::Array into the map; mirror PHP's array $config type juggling by raising a TypeError for non-array decode results. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-06fix(array-dumper): emit package links and require Link pretty constraintnsfisis
Resolve the phase-b TODO that left the supported-link-types loop as dead code (links were always an empty Vec), so requires/conflicts/provides/ replaces/require-dev are dumped again via PackageInterface::get_links_for_type, matching the PHP magic-call loop. Every Link in production is constructed with a pretty constraint (all ArrayLoader/AliasPackage/PlatformRepository/InstalledRepository sites pass one), so make Link::pretty_constraint a required String instead of Option<String>. get_pretty_constraint() now returns &str directly rather than anyhow::Result<&str>, dropping the unreachable UnexpectedValueException guard, and all call sites are updated. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-04feat(loader): wire RootPackageLoader::load end-to-endnsfisis
Resolve the remaining todo!()/placeholder sites in RootPackageLoader::load so the root package loads with real data: - Unbox config at use sites and change load()'s parameter from IndexMap<String, Box<PhpMixed>> to IndexMap<String, PhpMixed>, matching ArrayLoader::load / VersionGuesser::guess_version and dropping the redundant box/unbox round-trip at the factory call site. - Expose replace_version through CompletePackage/RootPackage inherent delegation and a RootPackageHandle method (PHP Package::replaceVersion, inherited), and apply it for the auto-versioned default. - Collect require/require-dev links via getter dispatch and build the pretty-string map feeding extractAliases/StabilityFlags/References. Also reconcile the package repositories type with Config: change CompletePackageInterface::{get,set}_repositories from Vec<IndexMap<String, PhpMixed>> to IndexMap<String, PhpMixed> (PHP's array<int|string, mixed>), wire setRepositories(config.getRepositories()), and dump repositories verbatim as a keyed array (matching PHP ArrayDumper) instead of forcing a list. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-04feat(loader): wire ArrayLoader::load end-to-end ↵nsfisis
(create_object/configure_object/dispatch) Make ArrayLoader::load build and return a fully configured package for both the CompletePackage and RootPackage class strings. - Introduce a private CompleteOrRootPackage enum to model PHP's createObject(): CompletePackage return (RootPackage extends CompletePackage), with accessors for the inner Package, the CompletePackageInterface view, and conversion into a PackageInterfaceHandle. - create_object: instantiate CompletePackage/RootPackage by class string. - load / configure_cached_links: implement the dynamic setter dispatch ($package->{'set'.ucfirst($method)}($links)) via apply_link_setter. - configure_object: wire all ~21 setters (Package inherent + CompletePackageInterface), source/dist with Mirror conversion, suggest self.version replacement, release date, and the branch-alias return (RootAliasPackage/CompleteAliasPackage). The PHP `instanceof CompletePackage` guard in configureObject is dropped: it is unreachable since createObject is private and returns `: CompletePackage`, an invariant now enforced at compile time by the enum. DateTime parsing for `time` keeps its existing approximate scaffold (noted with a TODO). RootPackage.inner is made pub(crate) (matching CompletePackage.inner) so the loader can reach the core Package. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-04feat: resolve trivial todo!() sites with existing constructorsnsfisis
Replace todo!("VersionParser::new()") with VersionParser::new() at 6 call sites (array_loader, base_command, create_project_command, vcs_repository, http_downloader x2) and EventDispatcher::io_clone with self.io.clone(). All targets already exist on their types. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-03fix(config,loader): wire JsonValidationException catch; drop unportable ↵nsfisis
chain TODOs JsonConfigSource::manipulate_json now downcasts the validate_schema error to JsonValidationException (matching PHP's specific catch), restores the original contents, and surfaces e.get_errors(); other errors propagate. ArrayLoader's two version-parse catch sites only had TODOs for preserving the original exception as 'previous'. shirabe_semver raises generic anyhow errors (not shim exception types), so the existing catch-all is already faithful to PHP's catch (\UnexpectedValueException), and the flat shim exception structs intentionally hold no previous field; the wrapped message already carries the original cause. Remove the stale TODOs. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

2026-05-22refactor: share Pool via Rc<RefCell>nsfisis

2026-05-22refactor(composer): unify Composer/PartialComposer via Rc handlesnsfisis
Model PHP's `Composer extends PartialComposer` as a PartialOrFullComposer enum and merge partial_composer.rs into composer.rs. Introduce ComposerHandle / PartialComposerHandle (plus their Weak variants) so the graph can be shared, and build it at once with Rc::new_cyclic in the factory to resolve the back-reference cycles.
