2026-08-31feat(plugin): serve Loop as a proxy stubnsfisis
Composer::getLoop() answers, so a plugin reaches the graph's own downloader and executor through the route Composer's own docblocks point plugin authors at, rather than through an instance of its own. wait() drains the promises it is given and rethrows the first rejection once the group is done, which is what React\Promise\all() hands PHP. abortJobs() has nothing to cancel while every request settles before the call that started it returns. A non-null $progress is an explicit error: a ProgressBar is a symfony/console object each world runs its own implementation of, so there is none to hand across.

2026-08-31feat(plugin): serve HttpDownloader's async surfacensfisis
add() and addCopy() answer with a promise, and enableAsync(), wait() and countActiveJobs() answer alongside them. The Rust future runs to completion before the promise is handed over, so requests a plugin starts together run one after another rather than overlapping; overlapping them needs a promise representation that crosses the boundary unresolved. Everything else the surface does is preserved. add() still refuses a downloader outside a Loop, and it does so by throwing out of the call the way PHP does, where a failed request instead arrives as a rejection the caller handles — __shirabe_rejected_promise is the failure half of the resolved- promise helper. wait() and countActiveJobs() answer for a downloader with no outstanding job, which, once every request settles before its call returns, it never has. This is where HttpDownloader parts company with ProcessExecutor, whose async surface stays an explicit error: executeAsync() resolves its promise with a Symfony Process, whose state is the proc_open() resource of whichever process called start(), where a request resolves its promise with a Response.

2026-08-31feat(plugin): carry Http\Response across as a materialized valuensfisis
A response is built for one request and the graph never retains it, so there is no entity for a handle to point at. The child holds a real instance instead, revived from the object record the wire carries, and collect() frees the copy each world holds — which is what that method is for. The value-object rule rejects the class only because collect() assigns to $this, so the category comes from an overrides.list entry. HttpDownloader::get() and copy() answer with one. Two gaps stay: decodeJson() reaches Composer\Json\JsonFile, which a guard shadows, and Composer answers a curl request with the CurlResponse subclass where this port flattens the value into a Response.

2026-08-31feat(plugin): serve HttpDownloader as a proxy stubnsfisis
A downloader carries its own options, TLS defaults and request backends, and what it shares with the graph is the IO it collects authentication into and the config it reads. Plugin code writing `new HttpDownloader($io, $config)` therefore allocates a Rust-side entity of its own rather than a second downloader the graph knows nothing about, and the guard that shadowed the class in the worker is gone. The request surface is not served yet: get() and copy() have no wire representation for the Response they return, and the async surface resolves its promises with one.

2026-08-30feat(plugin): carry an exception's class and state across the boundarynsfisis
A Rust-side failure reached plugin code as a RuntimeException whose message carried the name of the call that failed, so `catch (TransportException $e)` never matched and the status code the plugin branches on was gone. The Throw frame now names the class the exception was thrown as and carries the state that class declares beyond message and code. \Shirabe\MaterializedThrowable rebuilds it in the child: `new $class($message, $code)` for a class whose constructor has \Exception's shape, then the properties by reflection. A class the child cannot build that way keeps the RuntimeException shape. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-30feat(plugin): serve ProcessExecutor as a proxy stubnsfisis
Composer reaches this class two ways: the object graph hands one out through Composer::getLoop()->getProcessExecutor(), and plugins write `new ProcessExecutor($io)` freely. Both bind to a Rust-side entity, so the timeout the run shares -- seeded from process-timeout and rewritten while the run is in flight -- has one value instead of one per world, and the executor can still be passed to the classes that take one (`new Filesystem($process)`). Three things the stub generator was missing came with it: - By-ref parameters. The call carries their positions and the answer carries what each holds afterwards; a position the answer omits was never assigned to, which is what PHP does with an untouched by-ref parameter. ProcessExecutor::execute is the only one on a proxied class. - Argument arity, reproduced where the real body reads func_num_args(). execute($cmd) forwards the child's output and execute($cmd, $out) captures it, and nothing but the argument count separates the two. - Static methods that cannot run in the worker. One that reads a static property the Rust side owns, or that reaches a guarded class, forwards through __shirabeCallStatic instead of being materialized. That also fixes Filesystem::isLocalPath and getPlatformPath, whose materialized bodies called the guarded Composer\Util\Platform. The async surface stays an explicit error. executeAsync resolves its promise with a Symfony Process, whose proc_open() resource and pipes belong to whichever process called start(), so a Rust-side spawn has none to hand back; running the real start() in the worker needs a promise representation that crosses the boundary unresolved. The fixture project drives the whole synchronous surface from plugin code and compares the trace against upstream Composer byte for byte.

2026-08-23fix(fs): carry file_get_contents results as bytesnsfisis
file_get_contents() and file_get_contents_with_max_length() return Vec<u8> instead of a from_utf8_lossy'd String. Call sites whose consumer takes a &str still convert lossily and are marked TODO(bytes). file_get_contents_with_max_length() now reads at most the requested number of bytes instead of the whole file. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-22test(show-command): run test_self againnsfisis
date() renders in the system default timezone, so the mismatch the ignore described is gone; the test passes with the local date ahead of or behind the UTC date. test_show_outdated_deps_sorting_by_age still fails that way, because ShowCommand::get_relative_time formats the release date in UTC while taking "today" from date(). Its ignore now says so on its own.
2026-08-22fix(package): dispatch get_links_for_type on Link::TYPE_* valuesnsfisis
PHP resolves a link kind through `$package->{'get'.ucfirst($linkType)}()`, so the argument is a `Link::$TYPES` value ("requires", "devRequires", ...). The helper matched the composer.json key names ("require", "require-dev", ...) instead, so every caller passing a `Link::TYPE_*` constant got an empty map back: `show <package>` printed none of its requires/provides/conflicts/ replaces sections, and `--format=json` carried none of those keys. The two callers that were passing composer.json keys now pass the matching `method`, as PHP does.
2026-08-22fix(event-dispatcher): run COMPOSER_BINARY without a PHP interpreternsfisis
`@composer <args>` and a bare `composer <args>` script both re-enter the binary running the script, taken from COMPOSER_BINARY. That path used to be prefixed with the PHP interpreter command, which produced `php <shirabe path> install` and could not run: Shirabe ships as a native executable, not a phar. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-22feat(cli): tell the user to run `shirabe`, not `composer`nsfisis
Messages that instruct the user to run a command named the Composer binary. Shirabe ships as its own binary, so the hints now name it. File names (composer.json, composer.lock), the "composer" repository type and prose about Composer itself are untouched. The installer and functional integration fixtures live in the Composer submodule and cannot be edited, so their expected output is normalized on load.
2026-08-22ci: setup GitHub Actionsnsfisis
2026-08-20fix(event-dispatcher): let a PHP script reach the Composer object graphnsfisis
A PHP script listener that walks the event it receives (Laravel's Illuminate\Foundation\ComposerScripts::postAutoloadDump asks for $event->getComposer()->getConfig()->get('vendor-dir')) aborted the run with `unknown Rust handle 2`. The event's getComposer/getIO answers register an entity in the R table and hand back its rhandle, but ScriptRpcDispatcher resolved only rhandle 0 and the one event handle of the call in flight, so it could not serve a method on a handle it had just minted itself. The R-table lookup PluginRpcDispatcher already does is now dispatch_r_table_method, shared by both. The stubs that graph hands out extend and implement the real Composer contracts (Composer\Package\PackageInterface and the rest), which live in the Composer PHP runtime and not among the generated stubs or guards, so execute_event_php_script loads that runtime the way the plugin and command-class paths do.

2026-08-19perf(package): hand out link maps behind Rcnsfisis
PackageInterface::getRequires() and friends return the array of Link objects; in PHP that is a copy-on-write array of object references, so a caller pays nothing to look at it. The port returned IndexMap<String, Link> by value, so every call deep-cloned the whole map, keys and constraints included. Pool building calls these accessors once per package per candidate, which put IndexMap::clone at 13.5% of `require laravel/laravel`. Store the maps as Rc<IndexMap<String, Link>> and return a handle. Callers that mutate the map clone it explicitly at the point of mutation, matching where PHP would separate the array. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-19fix(input): thread a typed InputValue through the input layernsfisis
Options and arguments were stored and passed as PhpMixed even though Symfony only ever puts a string, a bool, a list of strings or null in one. get_option already narrowed to InputOptionValue at the boundary; this widens that enum into InputValue and pushes it through InputInterface, InputOption/InputArgument defaults, the Input storage, ArgvInput/ArrayInput/StringInput/CompletionInput, Command::add_option and add_argument, and the Composer-side wrappers. Two neighbouring string|int unions get types of their own: InputDefinition::{get_argument,has_argument} take an ArgumentName, and ArrayInput keys its parameters by ParameterName. has_parameter_option and get_parameter_option take the values they look for as &[&str], which is what PHP's `(array) $values` cast produced anyway. Two behaviours change along the way. Input::set_option on a negated option now negates with PHP's loose bool cast rather than treating a non-bool as false, matching `!$value`. ArrayInput::parse now resolves an integer key to an argument position instead of looking up an argument literally named "0". Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-18perf(metadata-minifier): defer copying versions out of expandnsfisis
MetadataMinifier::expand now returns ExpandedVersions, which holds the minified input plus, for each expanded version, a table of references to where its fields live. A version is copied only when materialize() asks for it. ComposerRepository::load_async_packages runs its constraint and stability filters straight off that view through the new VersionFields trait, so the versions it rejects are never copied at all. Benchmarks are new under crates/shirabe/benches. load_packages against real packagist p2 metadata, before -> after: symfony/console (768 versions) 0 accepted 9.01 ms -> 4.40 ms -51% 50 accepted 10.70 ms -> 6.30 ms -41% 147 accepted 13.17 ms -> 9.62 ms -27% 329 accepted 18.58 ms -> 16.89 ms -9% 663 accepted 27.27 ms -> 27.89 ms +2% laravel/framework (1277 versions) 0 accepted 39.44 ms -> 11.22 ms -72% 81 accepted 44.76 ms -> 18.25 ms -59% 840 accepted 125.44 ms -> 120.12 ms -4% 1266 accepted 163.18 ms -> 182.01 ms +12% The crossover sits near 80% acceptance. Past it the view loses, because materialize rebuilds a map where the old code cloned one, and the minified input stays alive alongside the copies; the 1266-of-1277 case measured between +5% and +12% across runs. Loads with a real constraint sit far below the crossover. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
2026-08-18fix(input): return a bool|string|string[]|null enum from get_optionnsfisis
`InputInterface::get_option` returned `PhpMixed`, so the negation branch of `Input::get_option` reproduced PHP's `return !$value;` as `!value.as_bool().unwrap_or(false)`, which inverts the result for a string value instead of leaving it `false`. It now returns `InputOptionValue`, whose `to_bool` is PHP's truthiness cast. The narrowing also removes the `Vec<PhpMixed>` element handling the commands carried for array options: `as_array` hands back `&[String]`, so the `filter_map(|v| v.as_string())` chains at eight call sites collapse. Its other accessors keep `PhpMixed`'s names and meanings (`is_null`, `as_bool`, `as_string`, `to_bool`), and `From<InputOptionValue> for PhpMixed` covers the callers that feed the value back into an `IndexMap<String, PhpMixed>` or a `PhpMixed` parameter. `Input` keeps its parsed options and `InputOption` its defaults as `PhpMixed`, so `Input::get_option` is where the narrowing happens and where a value outside the domain panics.

2026-08-18fix: propagate ported exceptions instead of flattening themnsfisis
`ProcessExecutor::execute_args` existed only to turn `execute`'s `anyhow::Result` into an exit code of 1, so every one of its ~87 call sites silently took the "command failed" branch on an error PHP would have thrown. It is gone; callers use `execute` and propagate with `?`. Where the enclosing function had no `Result` to propagate into, its signature grew one, up to and including `Git::get_version`, `Svn::binary_version`, `GitHub`/`GitLab`/`Bitbucket::authorize_oauth`, `InitCommand::get_git_config` and `DiagnoseCommand::check_git`. The VCS drivers had the same problem in the other direction: their `get_contents` returned `Result<Response, Box<TransportException>>`, a type too narrow for the PHP method, which lets any Throwable out of the `catch (TransportException $e)` block. Every non-transport error was therefore rewritten into a `TransportException` with code 0, which the callers switch on. They now return `anyhow::Result<Result<Response, Box<TransportException>>>`: the outer `Result` carries what PHP does not catch, the inner one the exception the drivers handle. That signature also restores `GitLabDriver::getContents`: the 400/401 `TransportException`s it raises to force authentication are thrown inside its own `try` block and handled by its own `catch`, but the port returned them straight to the caller, so the authentication flow behind them never ran. `impl_php_exception!` gains `From<Box<$ty>> for anyhow::Error` so a caught exception can be re-propagated with `?`.

2026-08-18fix(process-executor): model commands as a CommandLine enumnsfisis
Commands were carried as `PhpMixed`, whose `String`/`List` variants do not tell a shell command line apart from an argv list at the type level. `Perforce::execute_command` and `Git::run_command` therefore funnelled string commands through `execute_args`, spawning `p4 set` or `git command` as a single argument instead of running it through a shell as PHP does; their tests were written against that shape. Introduce `CommandLine::{Shell, Args}` and use it for every `ProcessExecutor` entry point, the mock expectation queue and the `Git::run_command` callables. The unreachable "Invalid command type" branches disappear with it, and the affected tests go back to the string expectations the PHP suite uses.

2026-08-18refactor(preg): add preg_is_match for existence-only call sitesnsfisis
The capture groups were discarded at 162 of the preg_match call sites, which only tested the Option. They now call preg_is_match, which lets the regex engine skip capture tracking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-18refactor(preg): drop the offset argument from preg_matchnsfisis
Every call site but one passed offset 0. The remaining one, the UTF-8 chunking loop in Application, slices the subject instead: its pattern has no anchor or lookaround, so matching a suffix is equivalent to starting the search at that offset. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-18refactor(pcre): inline Preg into its call sites and drop the cratensfisis
Preg had shed everything it owned: after the last few rounds its methods were one-line forwards to the shim's preg_*(), differing only in a default argument or a wrapper the caller unwrapped anyway. The 460 call sites now name the shim function, and shirabe-pcre is gone from the workspace along with its LICENSE entry. The forwards expand as they read: isMatch becomes preg_match2(.., 0).is_some() (is_none() where PHP negates it), isMatch3 and match3 drop the .is_some(), matchAll counts through preg_match_all2(..).occurrence_count(), and replace4/replace5 spell out the limit and count arguments preg_replace2 takes. Callbacks are the one place the shapes differ: preg_replace_callback carries an error out of the callback, so the fourteen infallible closures wrap their result in Ok() and expect() it back. Config::process() is the fifteenth, and it drops the `error` cell it captured to smuggle a failure past a closure that could only return a String. The `?` in the closure now carries it, which is what the PHP does -- a throw from the callback leaves preg_replace_callback at the failing match rather than running the remaining replacements and reporting the last error. The module doc that explained why composer/pcre's exceptions and *StrictGroups() variants have no counterpart moves to the shim's preg module, where the functions it describes live.

2026-08-18refactor(preg): split PregMatches reads into get() and name()nsfisis
PregMatches keyed both forms of a capture group through CaptureKey, so every read built one: a usize wrapped in an enum, or worse, a String allocated to name a group that regex::Captures can look up from a &str. It now mirrors regex::Captures instead -- get() takes the group number, name() the group name -- and the enum drops out of the type entirely. That is 285 call sites across 59 files, and the named ones carry most of the win: `matches.get(&CaptureKey::ByName("host".to_string()))` reads as `matches.name("host")`. ProcessExecutor loses a `user_key` binding that existed only to build the key once. CaptureKey stays as the key type of PregMatchesAll and PregMatchesAllWithOffsets, where numbered and named entries share one IndexMap and a key type is the point. Five files still name it. Also retargets the two preg_match_all comments that described the occurrence count through `matches[&CaptureKey::ByIndex(0)].len()`, an Index impl these types no longer carry. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-18refactor(pcre): hand back the match instead of copying it outnsfisis
Preg::match4 and Preg::replace_callback gave callers a PregMatchedGroups: an IndexMap rebuilt from the match with an owned String per group, plus a second String for a named group's name key. That is the copy PregMatches shed when it started wrapping regex::Captures, reinstated one layer up -- and nearly every regex call in the tree goes through Preg rather than the shim's preg_* directly, so almost nothing saw the borrow. PregMatchedGroups existed only to drop the null (unmatched) groups the old PregMatches held as Option<String> values. PregMatches::get reports a non-participating group as None on its own, so the two read alike and the type collapses into it. Call sites still reach groups through get(&CaptureKey::ByIndex(N)); what changes is that the value arrives as a &str borrowed from the subject, which the signatures now carry as a lifetime. Three places needed the borrow reckoned with rather than a mechanical rewrite: PhpFileCleaner::clean and Problem::get_messages read their groups out before mutating what the match borrows, and Git::get_authentication_failure names the lifetime of its url argument, which the result borrows instead of self. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-17refactor(pcre): return the Preg $matches instead of filling an out-paramnsfisis
`Composer\Pcre\Preg` fills `$matches` through a by-ref parameter, and the port mirrored that with a `&mut` (or `Option<&mut>`) out-param plus a bool or count return. Callers had to declare an empty map one line ahead of the call, and the type never said the map is only meaningful when the call matched. Return the matches instead: - match3/match4/is_match3/is_match4 -> Option<PregMatchedGroups> - is_match_named -> Option<PregNamedGroups> - match_all2/is_match_all -> PregMatchesAll - is_match_all_with_offsets3 -> PregMatchesAllWithOffsets Nothing is lost: the bool is `Option::is_some()`, and the occurrence count is the length of any one column of a PREG_PATTERN_ORDER map, now spelled `PregMatchesAll::occurrence_count()`. is_match() still answers the bool question directly for callers that want no groups. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-17refactor(preg): wrap the preg_* $matches maps in newtypesnsfisis
The five IndexMap shapes that the preg_* functions and Preg fill in are now distinct types generated by preg_match_map!, so a matches map no longer interchanges with any other map of the same key and value type. Index<usize> is kept alongside Index<&Q> because call sites such as config_command and event_dispatcher reach for a group by its position in the map rather than by its capture key.
2026-08-17fix(platform): expand the %VAR% form in expand_path()nsfisis
The alternation that stands in for the original conditional subpattern reports the branch it did not take as an empty string, so `dvar` was always present and won over `pvar`, leaving %VAR% unexpanded. `\w+` cannot capture an empty string, so an empty branch means it did not participate. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-17refactor(preg): replace Preg::split*() with shim preg_split*()nsfisis
preg_split2()'s limit was always -1 and its flags were always either 0 or PREG_SPLIT_DELIM_CAPTURE alone, so both arguments are gone: the shim now exposes preg_split() and preg_split_delim_capture() over a shared preg_split_impl(). That leaves Preg::split()/split4() as bare pass-throughs, so callers use the shim functions directly and the wrappers are dropped along with the now-unreferenced PREG_SPLIT_* constants. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-17refactor(preg): drop unused args of preg_match_all_offset_capture2()nsfisis
The sole caller, Preg::match_all_with_offsets5(), always passed flags=0 and offset=0, so PREG_UNMATCHED_AS_NULL is now unconditional and the subject is scanned from the beginning. That method is only reached from Preg::match_all_with_offsets(), so it is no longer public either. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-16test: correct stale #[ignore] reasonsnsfisis
Running the ignored tests shows several reasons naming a blocker the test never reaches. The plugin hooks in all_functional_test do run, and what stops both cases is the worker's Composer\InstalledVersions; class_loader_test stops at include_file, not class_exists; auth_helper_test's wrapper is ported and the blocker is trigger_error; composerRequire is ported as __shirabe_composer_require. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-16refactor(tests): share the PHP worker helpers with the plugin binarynsfisis
plugin_installer_test.rs carried its own copy of php_runtime_available, lock_php_worker and load_composer_php_runtime, and the other ten files in the binary imported them from there. The bodies matched tests/common/php_worker.rs, so include that instead. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-16fix(autoload): expand the dirsep placeholder in target-dir patternsnsfisis
AutoloadGenerator.php builds the target-dir pattern by quoting the path with a <dirsep> marker in place of the separators, then replacing the quoted marker with [\\/]. The port kept that shape, but preg_quote() here deliberately leaves < and > alone so the regex crate does not read \< as a word boundary, so the replacement never matched and the pattern came out as the literal {^Main<dirsep>Foo<dirsep>}. A root package's target-dir was therefore never stripped from files, classmap or exclude-from-classmap, and dumping one failed outright. Split on the separators and quote each segment instead, so the marker never passes through preg_quote() at all. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-16refactor(env): route Shirabe's own env reads through the shimnsfisis
These sites have no PHP counterpart to mirror, so they read std::env directly. Going through the shim's getenv() keeps every environment read in one place and lets a lint forbid the direct form. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-16feat(plugin): proxy Composer\Util\Filesystem into the plugin workernsfisis
The class was shadowed by a guard, so a plugin doing `new Filesystem()` got an explicit error. It is classified rust-proxy and plugin-constructible and the Rust port is complete, so listing it as a stub target and answering its public surface from the entity is all it takes. The constructor rejects a caller-supplied ProcessExecutor: that class has no proxy stub, so the argument could only be a second instance the Rust side never sees. findShortestPath re-checks its arguments at the boundary because the port panics where PHP throws, and a panic would take the process down instead of reaching the plugin's catch block. phpstan/extension-installer matches upstream Composer byte for byte again.
2026-08-16feat(php-rpc): replay Rust-side env writes into the PHP workernsfisis
The worker is a long-lived child holding the environment it was handed at spawn, so `@putenv`, the bin dir the event dispatcher prepends to PATH, and COMPOSER_DEV_MODE never reached the PHP code running in it. The shim now journals every write to the three storages PHP exposes, and the outermost rpc_call replays the entries the worker has not seen yet through __shirabe_sync_env. Replaying the writes rather than pushing a whole snapshot keeps the worker's own $_SERVER entries intact. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-16feat(plugin): guard Rust-owned classes the worker has no proxy fornsfisis
The worker's autoloader fell through to the real Composer source for every Rust-owned FQCN without a proxy stub, so plugin code doing `new Filesystem()` or subclassing `LibraryInstaller` silently ran on a second instance the Rust side never sees. An unimplemented part of the plugin API has to fail with an explicit error naming it, not quietly work on a disconnected copy. The stub generator now emits a guard class for each of those FQCNs: the real declaration, hierarchy and constants, with every constructor and method raising an explicit error. References satisfied by the declaration alone (`instanceof`, `X::class`, `Link::TYPE_REQUIRE`) keep working. Two FQCNs stay resolvable to the real class, each listed with the worker-side mechanism that makes a natively constructed instance correct. The error had nowhere to go: `Installer::run` dropped the `Result` of both `dispatch_script` calls, so an exception from a listener ended in exit 0. Both propagate now, the way the exception does upstream. Three real-plugin E2E comparisons stop at a guard and are ignored, each naming the class it needs.

2026-08-16refactor(php-shim): split json_decode into assoc and obj variantsnsfisis
The assoc flag was always a literal at every call site, so the boolean carried no information the function name could not. json_decode_assoc and json_decode_obj make the resulting PhpMixed shape visible at the call site. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-16refactor(php-shim): give parse_url a typed UrlComponents resultnsfisis
parse_url now returns Option<UrlComponents> instead of a PhpMixed array, and the component-selecting overload with the PHP_URL_* constants is gone: callers read the field they want. Two call sites change behaviour as a result, both towards PHP: * CurlDownloader::handle_redirect tested scheme and host with is_null(), so an unparsable Location header (PhpMixed::Bool(false)) counted as an absolute URL. PHP's truthiness test sends it to the relative-path branch. * Url::get_origin appended a literal port 0, which PHP treats as falsy and leaves off. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-16refactor(io): take &str in ConsoleIO write and sanitizensfisis
doWrite, doOverwrite and sanitize accept PHP's string|list<string>, which this port modelled as PhpMixed. Every call site inside ConsoleIO passes a single string, so take &str and return String instead, dropping the (array) casts and the to_string_list helper. Auditor is the only caller that passed a list: it builds table rows, whose cells must stay separate, so it now sanitizes each cell. select() likewise sanitizes each choice while projecting them into the keyed form.

2026-08-16test(event-dispatcher): run PHPUnit-class listeners in the PHP workernsfisis
The listeners of five tests are methods of `Composer\Test\EventDispatcher\EventDispatcherTest`, which the worker could not load because the class extends `PHPUnit\Framework\TestCase` and phpunit is not part of the Composer runtime bundle. An empty stand-in for that base class is enough: a parent class only has to exist at declaration time, and method bodies and type declarations resolve lazily. The upstream file is then required into the worker unchanged, so the listener bodies and their `__DIR__` stay what Composer ships. The two assertions those bodies call are the only PHPUnit members the stand-in has to implement. `remove_listener` now compares a handle for an object the worker really holds instead of a hand-written one, and `create_composer_instance` wires the collaborators the autoloader-rebuild path reaches for, as the PHP helper does. Two tests stay ignored for a different reason: `Platform::put_env` writes only the Shirabe process environment, while the listeners read `getenv()` inside the long-lived worker.

2026-08-16refactor: narrow pub(crate) items to privatensfisis
Porting mapped every PHP `protected` member onto `pub(crate)`, which is wider than nearly all of them need. Each item demoted here is reached only from the module that defines it, so the crate-wide visibility conveyed nothing. Every `pub(crate)` that survives has at least one reader in another module of the same crate. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
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.

2026-08-15feat(php-shim): drop the modelled PHP version constantsnsfisis
The shim reported a fixed PHP 8.1.0 through PHP_VERSION, PHP_VERSION_ID, the major/minor/release triple and the PHP_WINDOWS_VERSION_* trio. Their uses split in two. Some guarded branches PHP only needs on runtimes this port cannot be: proc_get_status reports the exit status on every call, so Symfony's pre-8.3 exit-code cache has nothing to work around; hash_raw and hash_file always offer xxh3, so the sha1 fallback is unreachable; and http_get_last_response_headers is always available, so the pre-8.4 $http_response_header branch is gone. safeJunctions reads the host Windows version rather than PHP state, and joins the Windows work on hold. The rest ask about the PHP the user actually runs, and now reach the worker through a new php-rpc PhpVersion payload: the startup banner and the 7.2.5 warning, self-update's min-php filter, the ext-* recommendation in VersionSelector, the stream User-Agent, and whether PhpFileParser scans for enums.

2026-08-15fix(php-rpc): unpack the runtime bundle under the cache dirnsfisis
A worker whose PHP cannot read the bundle out of the executable gets it from an unpacked copy, which went to a directory derived from XDG_CACHE_HOME alone. That ignored COMPOSER_CACHE_DIR, COMPOSER_HOME and the cache-dir setting, and put the files outside the directory clear-cache and the platform conventions cover. The callers now pass Composer's configured cache directory down to base_path(). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-15feat(diagnose): audit the Composer runtime the executable carriesnsfisis
checkComposerAudit reported success instead of auditing anything, because the binary ships no vendor/composer/installed.json on disk. It reads the one in the embedded Composer PHP runtime now, and Composer's warning for a missing installed.json is back. Only that file leaves the bundle, into a temporary directory that goes away with the handle; the runtime is unpacked whole only for a worker that cannot read the bundle in place. Phar::extractTo's $files argument selects it, which the shim ignored so far. SHIRABE_COMPOSER_PHP_DIR moves into composer_runtime, so the worker and a reader on the Rust side resolve the runtime through the same branch. DiagnoseCommandTest::testCmdSuccess is ignored: packagist has advisories against composer/composer 2.9.7, the version Composer::VERSION reports, so diagnose exits 1 where the test expects 0. Upstream Composer 2.9.7 reports the same advisories. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-15feat(php-rpc): embed the Composer PHP runtime in the executablensfisis
Plugins and scripts need the real `Composer\` classes and the packages Composer depends on, which so far came from a checkout found through SHIRABE_COMPOSER_PHP_DIR or a path next to the workspace. Neither exists for a distributed binary. The build script now archives those PHP sources into a phar the way Compiler.php does and the executable carries it. The worker maps it with Phar::loadPhar and reads a content-addressed sentinel back to tell a bundle it can use from one it cannot; where its PHP cannot open the phar, the bundle is unpacked once into the cache directory and autoloaded from there. SHIRABE_COMPOSER_PHP_DIR still overrides both for development. PHP locates a phar's manifest by the first __HALT_COMPILER(); token in the file, so the executable must hold no other copy of it: phar.rs builds the token at run time, and a linter keeps further literals out of the sources that reach the binary.

2026-08-12test(installed-versions): verify the PHP class the worker loadsnsfisis
InstalledVersions has no Rust port, so the skeletons left behind asserted nothing about compatibility. The tests now require the Composer checkout's vendor/autoload.php into the PHP worker and drive the real class there, which puts $selfDir, the registered ClassLoader and Composer\Semver\VersionParser in the same state as the upstream PHPUnit run. The upstream setUp reflection and the installed_relative.php require stay in PHP; the expected values are Rust. The class Composer's own vendor directory autoloads and the one FilesystemRepository::write dumps from include_str! are separate files, so an added test asserts they hold the same bytes. FilesystemRepositoryTest::testSafelyLoadInstalledVersions moves to the worker too, against the php/stubs FilesystemRepository, whose safelyLoadInstalledVersions runs the PCRE recursive grammar natively. The shared worker helpers live in tests/common/php_worker.rs. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-12test: drop stale #[ignore]s and rewrite the run-script reasonsnsfisis
Measuring every ignored test with `cargo test --workspace --no-fail-fast -- --ignored` turned up 11 that pass today; their reasons named todo!()s and gaps that have since been implemented. The two run_script_command_test cases still fail, but not for the reason given: the user's Command class is imported and executed, and what is missing is only a way to observe it, since PhpCommandProxy::run forwards the run to the worker-side console application.
