2026-06-20feat(symfony-process): port full Process class from PHPnsfisis
Faithfully port every method, field and constant of Symfony's Process.php into process.rs, replacing the reduced stub. Add the supporting pipes module (PipesInterface/AbstractPipes/UnixPipes/ WindowsPipes), ProcessUtils and the missing process exceptions (LogicException/InvalidArgumentException) with constructors. Methods now return anyhow::Result where PHP throws, take the env argument and a bool-returning callback, and borrow &mut for status-updating accessors; all callers are updated accordingly. Extend the php-shim with proc_open/proc_close (PHP-compatible signatures), proc_get_status, proc_terminate, posix_kill, uniqid, ftruncate, ftell_stream, fseek3, stream_get_contents3 and env helpers.

2026-06-20refactor(php-shim): drop Box wrapping from PhpMixed List/Arraynsfisis
The List and Array variants of PhpMixed boxed their elements unnecessarily. Store PhpMixed values directly and update all callers accordingly. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-20fix(comparer): return instead of exiting the process on doTree failurensfisis
Composer's doCompare() calls `exit;` when the destination doTree fails, but the source branch handles the identical failure with `return;`. The asymmetry has been present since the class was first written (2413b55c6, 2018) and is almost certainly a bug. Treat it as `return` so a failed local-change detection no longer terminates the whole process. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-20feat(package): implement as_package_interface upcastnsfisis
Make the Rust-only as_package_interface a required trait method and return self from each concrete implementation, replacing the todo!() default that PHP needs no equivalent for (implicit subtype coercion). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

2026-06-20refactor: auto-fix clippy warningsnsfisis
2026-06-14fix(archiver): resolve infinite recursion in exclude filter dispatchnsfisis
The Phase B port invented an ArchivableFilesFilter trait whose filter impls called self.filter, recursing forever; the name also collided with the real ArchivableFilesFilter FilterIterator class. Composer has no such interface: the finder holds GitExcludeFilter/ComposerExcludeFilter (both extending BaseExcludeFilter) and calls $filter->filter(). Drop the invented trait, type the filters as Box<dyn BaseExcludeFilter>, and implement BaseExcludeFilter on the concrete filters (accessors delegating to inner). Remove the unused generic default methods from the trait so it is dyn-compatible; they remain as inherent methods on BaseExcludeFilterBase, which is where every caller already reaches them.

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>
2026-06-11feat(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(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(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.
2026-06-08refactor(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>
2026-06-07feat(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(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>
2026-06-07refactor(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>
2026-06-06refactor(version-bumper): share caller's VersionParser with ArrayLoadernsfisis
Mirror PHP's "new ArrayLoader($parser)" by passing the existing parser instead of None. VersionParser is stateless, so behavior is unchanged; this drops the phase-b TODO. Co-Authored-By: Claude Opus 4.8 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>
2026-06-06refactor(operation,link): port __toString to Displaynsfisis
Move __toString ports to std::fmt::Display: convert Link's inherent to_string() and make OperationInterface require Display instead of a to_string() method, with each operation implementing Display. Also fix the operation __toString output to use show(false), matching SolverOperation::__toString() (was show(true)). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-06refactor(link): drop phase-b shared-ownership TODOnsfisis
Link is an immutable value object and is never compared by reference identity, so cloning its fields is faithful to PHP. The shared-ownership TODO does not apply. 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>
2026-06-06fix(base-package): move equals to PackageInterfaceHandle for reference identitynsfisis
PHP BasePackage::equals uses === (reference identity), unwrapping AliasPackage on both sides first. A plain &self / &dyn PackageInterface cannot express this, so implement it on the shared handle where the Rc-based identity infrastructure (as_alias, get_alias_of, ptr_eq) already lives, and drop the unimplementable trait stub. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-06refactor(archiver): yield PathBuf from ArchivableFilesFinder, drop SplFileInfonsfisis
Migrate ArchivableFilesFinder off Symfony's SplFileInfo onto Path/PathBuf, resolving the phar_archiver TODO(phase-b) that required a .map() adapter to bridge SplFileInfo -> PathBuf. - ArchivableFilesFinder now yields PathBuf; accept() takes &Path; the exclude closure receives &Path and uses Path::canonicalize / is_symlink. The SplFileInfo -> PathBuf conversion happens once at the symfony get_iterator boundary (get_iterator stays SplFileInfo for cache.rs). - symfony Finder::filter callback changed to FnMut(&Path) (sole caller is the finder). - PharArchiver passes the finder straight into ArchivableFilesFilter, mirroring PHP's new ArchivableFilesFilter($files). - ZipArchiver consumes PathBuf items, computing the relative path via strip_prefix(sources) in place of SplFileInfo::getRelativePathname. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-06feat(archivable-files-finder): wire exclude closure into Finder::filternsfisis
Add a Finder::filter(Box<dyn FnMut(&SplFileInfo) -> bool>) stub method and route the exclude closure through it, matching PHP's ->in()->filter() chain. FnMut faithfully represents PHP's stateful \Closure. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-06fix(dependency-resolver): preserve PHP array keying for alias linksnsfisis
Mirror PHP's array_merge semantics in AliasPackage so self.version provide/replace/conflict links are appended under numeric keys ("0", "1", ...) instead of collapsing onto the target-name key. This keeps both the original and alias-version links and makes Pool::match's contains_key("0") check (= PHP isset($x[0])) work as intended. replace_self_version_dependencies now takes and returns IndexMap<String, Link>, dropping the lossy re-key-by-target in the AliasPackage/RootAliasPackage constructors. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-06refactor(repository): make read methods fallible and take &mut selfnsfisis
Change RepositoryInterface and WritableRepositoryInterface read methods (find_package, find_packages, get_packages, load_packages, search, get_providers, get_canonical_packages) to take &mut self and return anyhow::Result, so lazy-loading repositories such as ComposerRepository can perform fallible I/O and mutate internal state on access. Update all implementors and call sites to propagate the Result and pass mutable references. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-05refactor(json): model JsonFile encode/write options as a typed structnsfisis
Replace the i64 bitmask + encode_with_indent split with a JsonEncodeOptions struct (Default = JSON_UNESCAPED_SLASHES|JSON_PRETTY_PRINT|JSON_UNESCAPED_UNICODE, default indent). encode/write each get a default form plus an explicit encode_with_options/write_with_options variant, mirroring PHP's optional $options argument. write_with_options always encodes with self.indent, matching PHP write(). Also reconcile call sites with the PHP sources: most ported sites passed 0 where Composer omits the argument (= default flags), so JsonManipulator/ShowCommand and JsonConfigSource now use the default options; only ComposerRepository and Locker genuinely pass 0. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-06-05feat(filter): share platform req filter via Rc, drop clone_boxnsfisis
PlatformRequirementFilterInterface::clone_box (a todo!() trait-object clone stub) is removed in favor of Rc<dyn ...> shared ownership, matching PHP's by-reference sharing of the single filter object. Box<dyn ...> is replaced with Rc<dyn ...> across the factory, Solver/RuleSetGenerator, VersionSelector, AutoloadGenerator, Installer and the command layer (BaseCommand/PackageDiscoveryTrait and their impls); clone_box call sites become Rc clones. Co-Authored-By: Claude Opus 4.8 (1M context) <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(locker): wire get_locked_repository via LockArrayRepositorynsfisis
Implement LockArrayRepository::new/add_package and CanonicalPackagesTrait::get_packages (delegating to inner ArrayRepository), expose add_package on LockArrayRepositoryHandle, and add set_root_package_alias on CompleteAliasPackageHandle. With these in place, Locker::get_locked_repository is fully wired: load each locked package, register it (plus its aliasOf for AliasPackages) in package_by_name, then build CompleteAliasPackage handles for lock-file aliases via as_complete_package() narrowing. Drop the unused RepositoryInterface::clone_box default and the stale inherent LockArrayRepository::clone_box (no callers). 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(package): implement PackageInterface accessor layer for ↵nsfisis
Package/CompletePackage/RootPackage Fill the trait-impl todo!() across the package accessor layer so loaded packages are actually usable (the ArrayLoader::load path depends on it): - Package: implement BasePackage/PackageInterface from struct fields and existing inherent methods; Display via get_unique_name. - CompletePackage: delegate PackageInterface to inner Package. - RootPackage: delegate CompletePackageInterface/PackageInterface to inner CompletePackage; RootPackageInterface link setters delegate to Package. Correct three unfaithful trait signatures found during implementation: - get_target_dir returns Option<String> (PHP computes a normalized value; a borrow cannot represent it, and AliasPackage could not implement &str across its aliasOf handle). - RootPackageInterface link setters take IndexMap<String, Link>, matching Package and the real ArrayLoader caller (PHP RootPackage inherits Package::setRequires; the Link[] docblock was imprecise). - get_full_pretty_version takes a DisplayMode enum instead of a raw i64; the match is now exhaustive, so it returns String without an error path. Move mirror conversion to the boundaries: PackageInterface mirror methods use Vec<Mirror> (the typed form, matching the inherent methods), with array<->Mirror conversion done by the producer (ComposerRepository) and consumer (ArrayDumper). 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>
2026-06-03refactor(downloader,repository,json): drop stale try/catch TODOs; fix svn ↵nsfisis
getFileContent catch type Remove 17 TODO(phase-b) markers across exception-modeling sites where the existing single-Result closure+match already faithfully models the PHP try/catch (catch paths only rethrow, retry, log, or silently ignore and never yield a recoverable value, so a double Result is unnecessary). Fix SvnDriver::get_file_content to catch only RuntimeException (matching PHP's catch RuntimeException) and extract its .message instead of calling e.to_string() on the anyhow::Error, which would panic while the shim exception Display is unimplemented; other errors now propagate. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
2026-06-03feat(php-shim): align fwrite/touch2/PHP_OS_FAMILY/PHP_URL_SCHEME with PHPnsfisis
Adjust fwrite to return int|false equivalent (Option<i64>), add touch2 with mtime, implement PHP_OS_FAMILY via std::env::consts::OS, and swap the PHP_URL_HOST placeholders for the now-available PHP_URL_SCHEME. Wire these into locker, filesystem, platform, and remote_filesystem. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

2026-05-29refactor(repository): introduce typed LockArrayRepositoryHandlensfisis
Share LockArrayRepository via Rc<RefCell<_>> while preserving the PHP ?LockArrayRepository type strength: Request.locked_repository, Locker ::get_locked_repository, and the installer create_* helpers now thread the typed handle instead of an owned LockArrayRepository, and pool builder identity check becomes a strict ptr_eq via widening into RepositoryInterfaceHandle.

PHP packages have reference semantics, so introduce shared-ownership handles over an AnyPackage enum (PackageInterfaceHandle and friends) and replace Box<dyn PackageInterface> throughout. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
2026-05-23refactor(semver): change ConstraintInterface to a closed enumnsfisis
Replace the dyn ConstraintInterface trait objects with an AnyConstraint enum closing over its four implementors (Simple, Multi, MatchAll, MatchNone), mirroring the earlier Rule enum conversion. Rename constraint.rs to simple_constraint.rs to match the renamed Constraint type. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
