2026-06-14refactor(pcre): treat regex compile failure as fatal in shimnsfisis
The preg_* shim helpers wrapped their results in Option/Result solely to signal a regex that failed to compile. Composer never feeds a pattern that fails at runtime, so such a failure is a programming error: panic instead and drop the Option/Result wrappers, updating all callers. preg_replace_callback keeps its Result return type since the callback itself is fallible. preg_match_groups is removed in favor of preg_match at its sole call site. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-14refactor(pcre): consolidate duplicate preg_* shim helpersnsfisis
The preg.rs shim had several near-duplicate functions: simple helpers re-implementing logic already covered by their full-featured `2` variants. Delegate or remove the redundant ones while preserving behavior, and migrate the affected callers: - preg_replace / preg_split now delegate to preg_replace2 / preg_split2 - preg_match_all_simple removed; its caller uses preg_match_all - preg_split_chars removed; its caller uses a char-boundary iterator - preg_match_offset removed; its callers use preg_match2 directly Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-14refactor(pcre): move preg_* free functions into php-shimnsfisis
The free preg_* functions, the CaptureKey type, and the PREG_* constants move from the pcre crate into shirabe-php-shim, where the rest of the PHP standard-library shims live. Colliding names take a 2 suffix (preg_match2, preg_split2, etc.) since the shim already exposes differently-shaped variants. Preg keeps its public API and delegates to the relocated functions; CaptureKey is re-exported from composer::pcre so consumers are unaffected.

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>
2026-06-14feat(pcre): implement preg_* functionsnsfisis
Replace the todo!() stubs backing the Preg class and the standalone preg_* shim helpers with regex-crate implementations.
2026-06-14refactor(pcre): drop PcreExceptionnsfisis
Composer never feeds a pattern that fails to compile at runtime, so a preg_*() failure is a programming error rather than a recoverable condition. Replace the PcreException path with a panic. 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.
2026-06-14refactor(pcre): remove unused Preg methodsnsfisis
Drop the default-argument variants and offset-capture helpers that have no caller on the Rust side, along with the constants and free functions they were the sole users of. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

2026-06-14chore: add "ref" comments to file headernsfisis
2026-06-14feat(php-shim): port some functions to Rustnsfisis
2026-06-14feat(console): implement get_command_name_before_binding via input clonensfisis
Replace the todo!() stub with the real Symfony logic: clone the input, bind it against the application definition (ignoring binding errors), and read the first argument so the command name is detected even when global options precede it. Add a dup() method to InputInterface to model PHP's clone, derive Clone on the input types, and treat InvalidArgument/InvalidOption/MissingInput as ignorable ExceptionInterface errors during the pre-binding probe.
2026-06-13refactor(http): drop unworkable set_error_handler warning capturensfisis
PHP wraps fopen/file_get_contents/file_put_contents in set_error_handler to capture warning text into error_message. Rust reports I/O failures through return values rather than warnings, so this side channel cannot work; replace the calls with TODO(phase-c) notes and leave error_message empty until the I/O layer surfaces a reason. Also remove the now-unused set_error_handler_closure shim and make set_error_handler a no-op. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-13fix(console): flatten Application inheritance to restore overridesnsfisis
Composer\Console\Application embedded Symfony's Application as an `inner` field and delegated to it, so polymorphic calls inside the Symfony base (e.g. doRun -> $this->getLongVersion()) resolved to Symfony's own methods and never reached Composer's overrides. As a result `--version` bypassed Composer's getLongVersion()/doRun() entirely. Flatten the PHP inheritance chain into the single shirabe Application struct: take in the Symfony base methods (parent-calling overrides kept under a `base_` prefix) and drop the `inner` delegation. Replace the Symfony Application struct in shirabe-external-packages with an `Application` trait that the merged struct implements, so commands and descriptors can reference it without a reverse crate dependency.

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>
2026-06-12feat(php-shim): implement runtime functions to run --versionnsfisis
Replace todo!() stubs reached on the `composer --version` path so the command runs without panicking and exits cleanly: - introspection (function_exists, class_exists, extension_loaded, defined) via white-lists modeling a standard Linux PHP CLI - type casts: php_to_string/strval, php_truthy/boolval, substr, byte_at, explode, strtr_array - config/env: error_reporting, ini_get, date_default_timezone_*, server_get/server_contains_key, php_uname("s") - IO: turn PhpResource into an enum (Stdin/Stdout/Stderr/File) and implement fwrite/fflush/stream_isatty/php_fopen resource helpers - shutdown/exit: register_shutdown_function + run_shutdown_functions, exit, error_get_last - preg_match_all_offset_capture via the regex crate; the formatter pattern drops PCRE possessive quantifiers (original kept in a comment with a TODO) proc_open reports unavailable for now (TODO(phase-c)); terminal-size and tty detection fall back to defaults. sprintf calls on this path are rewritten with format!(). OutputFormatterStyleInterface gains clone_box to return shared styles. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-12feat(symfony-console): port Symfony Console and make the workspace compilensfisis
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-11feat(php-shim): implement realpath, putenv, and env/server mutatorsnsfisis
2026-06-11refactor(argv): use std::env::args instead of server_argv shimnsfisis
The server_argv() shim merely wrapped command-line arguments, so call std::env::args() directly at each use site and drop the unused shim.
2026-06-11feat(self-update): disable self-update commandnsfisis
The update flow differs fundamentally from the PHP phar-based one, and no release has been published yet, so the command would be meaningless. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-11feat(php-shim): implement trivial PHP-compatible stub functionsnsfisis

2026-06-11feat(bin): port composer entry point into main.rsnsfisis
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-11chore(compiler): drop compiler.rsnsfisis
The Compiler.php is PHP-tooling only (bin/compile) with no Rust equivalent, so it is not ported. Remove the compiler module along with the symbols used solely by it. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-11feat(console): resolve phase-b TODOs in doRun and IO wiringnsfisis
Wire up ConsoleIO with HelperSet/QuestionHelper, register the ErrorHandler with the IO instance, and fall back to a default output in run(). Replace resolved phase-b TODOs across the console, command, io, factory, installer, dependency_resolver, and util modules; reclassify the remaining blockers (typed Symfony command registry, stdin resource caching) as phase-c. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-10feat(repository): resolve repository phase-b TODOsnsfisis
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-10feat(phase-c): resolve cross-module phase-b TODOsnsfisis
2026-06-10feat(phase-c): resolve exception-handling phase-b TODOsnsfisis
* Catch specific exception types instead of broad/placeholder handling. * Drop the shim Countable trait.
2026-06-09feat(event-dispatcher): unify event dispatch via EventInterface traitnsfisis
Extract a superclass-trait EventInterface from the base Event. pool_builder's PrePoolCreateEvent stays deferred: its constructor needs owned, non-cloneable Request and repository boxes the builder only holds by reference (owned-payload blocker). The event is plugin-only, so its construction is re-tagged TODO(plugin). 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 PHP-array-semantics phase-b TODOsnsfisis
Resolve category K (array_* functions, integer keys, nested mutation, sorting). Add shim variants (uasort over Vec<T>, uasort_map for IndexMap) and delegate to existing typed variants (strtr_array, array_merge_map, array_search_in_vec). Implement PHP array semantics directly where the shape is fixed: canonical integer-key coercion (is_php_integer_key, shared by config and FilesystemRepository::dumpToPhpCode), strict array_search via trait-object pointer identity, array_reverse/array_chunk preserve_keys loops, and the installed.php nested version mutations via auto-vivify helpers. Resolving the array_merge in UpdateCommand unmasked latent borrow bugs in execute's tail (Rc input/output moved by value); fixed with .clone() to match PHP reference sharing, and resolved the tightly-coupled Intervals constraint check. composerRequire reclassified to phase-c: it depends on the $GLOBALS superglobal and PHP's require include mechanism, neither portable. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-08feat(phase-c): resolve static-property phase-b TODOsnsfisis
Implement the FileDownloader::$downloadMetadata accessors over the existing DOWNLOAD_METADATA static, and drop now-stale TODOs on the already-correct Platform::strlen function-local static and the ClassLoader include-closure no-op. 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 closure-capture phase-b TODOs in config/create-projectnsfisis
Port Config::process() to the real Preg::replace_callback, whose closure borrows &self/flags and calls get_with_flags; surface get() errors via a captured cell so process now returns Result. Switch the replace_callback shim bounds to FnMut to allow the error-capturing closure. Wire CreateProjectCommand suggestion collection through the Rc<RefCell> reporter's interior mutation. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-08refactor(external-packages): drop component segment from symfony pathsnsfisis
Align the Symfony namespace mapping with the documented convention (symfony::component::X -> symfony::X) and remove now-unused console stub files. Update all import paths across the workspace. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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>
2026-06-08feat(config): implement JsonConfigSource manipulate fallbacksnsfisis
Replace the 10 fallback-closure todo!()s in manipulate_json with real PhpMixed manipulation. The fallback rewrites the decoded composer.json when the JsonManipulator clean update fails. - manipulate_json: drop the args Vec and array_unshift_ref (the latter called the array_unshift shim and only existed to thread config through args). Fallbacks now take &mut config directly and capture typed values, mirroring the clean closures. fallback returns Result so insertRepository can throw on a missing reference repository. - Add private helpers: normalize_repositories_to_list, dedupe_repositories_by_name, set_nested, unset_nested, is_auth_config_key. - Faithfully mirror PHP quirks in the dormant fallback path, including the reset()+foreach double-walk of the first segment in add/removeProperty. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-07feat(phase-c): resolve dynamic-dispatch phase-b TODOsnsfisis
Replace the PHP `call_user_func([$obj, $method], ...)` / `$obj->{'get'.$x}()` dynamic dispatches (category E) with static Rust dispatch. - json_config_source: inject the clean-update as a typed `FnOnce(&mut JsonManipulator) -> Result<bool>` closure instead of a method-name string, dropping the call_user_func_array round-trip through PhpMixed args. The auth-config method override moves into the add/remove_config_setting closures. - config_command: dispatch addConfigSetting/addProperty on the concrete JsonConfigSource via match. - locker: select getRequires/getDevRequires and getReplaces/getProvides via match on the existing handle getters (previously stubbed to empty Vec). - create_project_command: reuse the existing get_links_for_type helper. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-07feat(phase-c): resolve &mut-access phase-b TODOs via handle settersnsfisis
PHP mutator methods that the Phase B port could not call because only &self / &dyn / Rc access was available. Resolved by the interior-mutation APIs that already exist: handle &self setters (set_dist/source_reference, set_requires/dev/references/stability_flags), Rc<RefCell<dyn InputInterface>> .borrow_mut(), and get_installation_manager().borrow_mut() (build_package_map passes an empty/canonical package list per upstream). composer.get_package() returns &RootPackageInterfaceHandle, so the "&dyn" Phase B note was wrong. factory's set_config_source/set_auth_config_source were already live code; their stale TODOs are removed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-07feat(phase-c): resolve owned-argument phase-b TODOsnsfisis
Replace value-by-value signature workarounds with proper ownership: - validate_json_schema: borrow JsonFile via ValidateJsonInput<&JsonFile>, restoring the dropped local auth file validation call - Auditor::audit / Solver::new / create_pool: pass cloned Rc handles and share Pool via Rc<RefCell<Pool>>; create_pool now takes &mut Request - MarkAlias{Installed,Uninstalled}Operation: hand over AliasPackageHandle from the alias-confirmed branch - dispatch_installer_event: clone the base Transaction (Rc-backed contents) and enable the PRE_OPERATIONS_EXEC dispatch - SuggestedPackagesReporter: share between command and installer via Rc<RefCell<>> to mirror PHP reference semantics PrePoolCreateEvent remains a TODO: it is plugin-only and would require a speculative Rc migration of Request whose payload is never read today.
2026-06-07refactor(phase-c): resolve shared-ownership TODOs via handle/Rc clonesnsfisis
Resolve the resolvable subset of category A (shared ownership / non-cloneable PHP class) TODOs by leaning on values that are already shared behind Rc/handle wrappers, where cloning preserves PHP reference semantics: - solver: call IgnoreListPlatformRequirementFilter::filter_constraint with a cloned AnyConstraint (a Clone enum) and propagate the Result - update_command: filter PlatformRepository out of the repository manager's handles into a CompositeRepository (array_filter equivalent) - package_discovery_trait: pass the real platform_requirement_filter (Rc clone) instead of substituting ignore_nothing() - installation_manager: pass the original full operation list (Vec<Rc<_>> clone) as all_operations - file_downloader: swap self.io to NullIO and restore via std::mem::replace - auditor: reuse the PackageInterfaceHandle list across the advisory and abandoned-package queries - process_executor: drop the unused, lossy Clone impl - config / array_repository: demote settled RefCell-design markers to comments Remaining category A items (factory installer wiring, purge_packages handle bridge, installer cache identity, reinstall flow, plugin command discovery) stay as TODOs since correct resolution needs structural refactors. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-07feat(metadata-minifier): port expand for minified package metadatansfisis
Implement MetadataMinifier::expand with the PHP list-of-arrays signature (Vec<IndexMap>) and wire it into ComposerRepository so composer/2.0 minified package metadata is expanded, resolving the phase-b TODO. minify() is left unported as it is not used in Composer itself. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-07feat(shirabe): resolve advisory instanceof TODOs via AnySecurityAdvisorynsfisis
Add an Ignored variant to the advisory enum (renamed to AnySecurityAdvisory) so the PHP three-class hierarchy PartialSecurityAdvisory -> SecurityAdvisory -> IgnoredSecurityAdvisory maps one-to-one onto enum variants. Replace the hard-coded auditor downcasts with as_security_advisory() (PHP `instanceof SecurityAdvisory`, true for both full and ignored) and as_ignored(), implementing severity/cve/source ignore filtering, the toIgnoredAdvisory conversion, and the table/plain row output faithfully. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-07feat(shirabe): resolve phase-b PhpMixed conversion TODOsnsfisis
Implement self-contained call sites that wrap/unwrap PhpMixed without touching shim bodies: platform-override and authentication IndexMap to PhpMixed conversions, and dev-package-name / version-alias sorts via usort with strcmp/strnatcmp. Drop stale TODO comments where the PhpMixed unwrap was already inlined. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-07refactor(phase-c): share PlatformRepository and RepositorySet via handlesnsfisis
PHP shares a single PlatformRepository by reference across the RepositorySet, createRequest, VersionSelector, and (in show) the installed repository. The port worked with owned values / &mut, so it could not share: create_repository_set silently dropped the platform repo from the pool (PlatformRepository is not Clone), show rebuilt a fresh PlatformRepository per use, and the package discovery / show version selectors were stubbed because VersionSelector wanted an owned RepositorySet. Thread the existing PlatformRepositoryHandle (Rc<RefCell<PlatformRepository>>) through installer.rs and show, restoring the RootPackageRepository + platform repo registration and implementing same_repository via RepositoryInterfaceHandle ptr_eq. Hold package-discovery repos as a shared RepositoryInterfaceHandle, and share RepositorySet as Rc<RefCell<RepositorySet>> in the set caches and VersionSelector (which only reads it), unblocking both stubbed selector sites and dropping show's placeholder set. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-07feat(shirabe): resolve phase-b TODOs with shared ownershipnsfisis
Replace TODO(phase-b) placeholders (todo!() and commented-out code) with real implementations: - Share JsonFile via Rc<RefCell<JsonFile>> so JsonConfigSource and the owning command can hold the same instance (base_config_command, config_command, repository_command, require_command, create_project, remove_command, factory) - Change InstallerInterface methods (is_installed, download, prepare, cleanup, get_install_path) to &mut self so initialize_vendor_dir can run, propagated to all installer implementations - Pass io/config/filesystem/process by clone instead of moving or stubbing (auth_helper, svn_driver, curl_downloader, library_installer) - Make TransportException Clone and store it by value in VcsRepository - Clone operations in Transaction sort, root_aliases/temporary_constraints in RepositorySet::create_pool, and share CompletePackage via handle in PlatformRepository - Wire up set_option, set_requires/set_dev_requires, installation manager setters, BumpCommand::set_composer, and clean_backups/set_local_phar
2026-06-06fix(git): run git --version in getVersionnsfisis
The execute call was stubbed out during Phase B, so getVersion never ran git --version and always reported no version. Wire it to ProcessExecutor::execute_args. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-06feat(vcs): implement VcsDriverInterface for all VCS driversnsfisis
Reconcile the VcsDriverInterface trait with the concrete drivers so every driver implements it as in PHP, where each driver extends VcsDriver. - Make cache-mutating getters take &mut self in the trait, matching the inherent methods' lazy-cache semantics; update vcs_repository consumers. - Change supports() to take Rc<RefCell<Config>> and return Result<bool>, completing GitDriver::supports deep ls-remote and its config wiring. - Add base get_composer_information to Git/Hg/Fossil/Perforce and an impl VcsDriverInterface block to every driver, delegating to inherent methods and absorbing type differences in the impl. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-06feat(binary-installer): use file_get_contents with offset and lengthnsfisis
Add file_get_contents5 shim supporting use_include_path/context/offset/ length, and wire it into BinaryInstaller to read the first 500 bytes of the bin file, replacing the offset-less stub and its phase-b TODO. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-06chore(shirabe): remove ports of PHP @deprecated APIsnsfisis
Composer does not use its own deprecated APIs internally, so drop their Rust ports: whole deprecated classes, methods, constants, and field. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
