The two functions ran the same search and differed only in how they
reported a non-participating group: one as ("", 0) in a bespoke struct,
the other as (null, -1) in a capture-key map. Neither shape covered both
callers, because PHP reaches preg_match_all() with different flags from
each: Preg::matchAllWithOffsets() always ORs in PREG_UNMATCHED_AS_NULL,
while OutputFormatter::formatAndWrap() passes PREG_OFFSET_CAPTURE alone.
Keep the capture-key map, which also exposes named groups, and take the
flags that decide between null and "" for an unmatched group. The offset
is -1 either way, so the ("", 0) approximation is gone.

PHP's Preg::matchAll() and matchAllWithOffsets() always set
PREG_UNMATCHED_AS_NULL, so a non-participating group is `null` and its
offset is -1. The Rust wrappers collapsed those to "" and 0, so callers
could not tell a group that did not participate from one that matched an
empty string at offset 0, and the offset value matched no PHP mode at
all.
Hand the shim's representation through unchanged and let each caller
mirror what the PHP original does with it: `isset()` and `(string)`
casts stay lenient, while `assert(is_string(...))` and the
*StrictGroups() variants become `expect()`.

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.

Every caller reached preg_match_all2() through Preg::match_all5(), which
always passed flags = PREG_UNMATCHED_AS_NULL and offset = 0. Inline those
constants and make match_all5() private, since the two public wrappers are
its only callers.

Callers had to build a temporary Vec<&str> at every call site to satisfy
the &[&str] parameter. Taking IntoIterator and yielding the matched items
lets them pass owned or borrowed strings directly.
The flags variant and PREG_GREP_INVERT go away with it: no caller passes
flags, and Composer's Preg::grep() has no such parameter either.

preg_replace_callback2 had one caller, Preg::replace_callback6, which
was itself reached only from Preg::replace_callback with the default
limit, count and flags. Fold the two shim functions into one and drop
those parameters along with replace_callback6.
The surviving callback takes callback2's IndexMap of matches: it can be
keyed by group name, and it omits trailing non-participating groups the
way PHP does, which is what the callbacks in Process and ProgressBar
test for.

The stub token search compared every 18-byte window of the file case
insensitively. The token starts with a byte that ASCII case folding
leaves alone, so memchr can pick out the candidate offsets and leave
only those to the case-insensitive compare.
Over the 35 MB executable, finding the token in the embedded bundle
stub drops from 2.3 ms to 0.1 ms, and a scan that finds nothing drops
from 24 ms to 3.6 ms.

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.

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.

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.

This is the type Filesystem::directory_size() actually iterates, and it
swallowed a failed stat as 0 the same way. PHP's iterator yields
\SplFileInfo there, so raise the same \RuntimeException it would.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

\SplFileInfo::getSize() throws a \RuntimeException when stat fails, and
neither Symfony's subclass nor Composer's Filesystem::directorySize()
catches it. Returning 0 turned an unreadable file into an empty one.

PHP keeps three separate environment storages and docs/dev/env-vars-
porting.md maps each to its own shim construct. Reaching for std::env
silently picks one, so the porting target has to be chosen by reading
the PHP source rather than by whichever Rust call is at hand.
Detect var/var_os/vars/vars_os/set_var/remove_var. current_dir, args,
consts, temp_dir, current_exe and the path split/join helpers are not
environment storage and stay allowed.

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.

CaBundle::getEnvVariable() prefers $_SERVER and falls back to getenv()
only under the CLI SAPI. The port read the live process environment for
both SSL_CERT_FILE and SSL_CERT_DIR, skipping the snapshot entirely.

ProxyManager::initProxyData() reads $_SERVER[$name], a startup snapshot,

after startup changed the proxy the port picked but not the one PHP
would pick.

Factory::useXdg() enumerates array_keys($_SERVER). The port enumerated

The signature took usize, so PHP's negative $start and $length, which
count from the end of the string, could not be expressed. Take i64 and
an optional length, and apply PHP's clamping rules.

serialize(), var_export() and the string cast each hand-rolled
`format!("{}", f)`, which never emits PHP's exponential spelling and
carries the wrong precision for the string cast. PHP writes 1.0E+20
where Rust writes 1e20, and (string) 1/3 is 0.33333333333333, not the
shortest round-trip form.
Delegate all three to smart_str_append_double, which shirabe-php-src
already provides and shirabe-php-rpc's codec already used: precision -1
for serialize() and var_export(), 14 for the string cast.

Rust's shortest float formatting rounds a tie away from zero where
zend_dtoa mode 0 rounds to even, so digits taken straight from `{:e}`
diverged from PHP on values such as -166050639803968.125.
Take only the digit count from `{:e}` and re-format at that fixed
precision, which rounds the exact decimal value half to even. The same
routine supplies the fixed-precision mode `php_gcvt` previously refused
with an assert, so both modes now share one path.

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.

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.

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.

json_decode built a serde_json::Value first and then converted it. Drive
serde_json's Deserializer with a DeserializeSeed instead, so the value is
built in one pass without the intermediate representation.

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

Config::get() resolves cache-files-maxsize by matching the stored value
against a size regex. The port read that value with as_string(), which
yields None for anything that is not a string, where PHP casts with
(string).
create-project feeds Config::all() back through Config::merge(), so the
second read finds the byte count the first read produced rather than the
original "300MiB". as_string() then yields an empty string, the regex
fails, and the resulting RuntimeException is swallowed by Config::get(),
which maps Err to null. FileDownloader turns that null into a zero max
size via .as_int().unwrap_or(0), and Cache::gc() deletes every file in
the download cache because the total always exceeds zero.
Apply the same cast on the path branch, the other site where Config.php
writes (string).

fstat and lstat now return Option<FileStat> instead of a PhpMixed array, so
Platform::is_tty and Filesystem::is_junction read `mode` as a field. The
array carried each of the 13 values twice — once under its numeric index and
once under its name — which no caller relied on, and building it spelled the
field list out four times.

posix_getpwuid now returns Option<PasswdEntry> instead of a PhpMixed array,

posix_getuid and posix_geteuid return u32, matching the uid PasswdEntry is
looked up by.

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.

SymfonyStyle modelled PHP's string|array message parameters, its array of
listing elements and its table headers/rows as PhpMixed, then normalised
and stringified them at every entry point. Take &[String] for the message
and listing parameters, Vec<Cell>/Vec<Row> for table (matching the
horizontal_table signature) and Vec<String> for the choice options, so the
is_array/is_iterable normalisation and the php_string helper both go away.
PhpMixed stays where PHP is genuinely mixed: the question answers returned
by ask/ask_hidden/choice, their validators, choice's string|int|null
default, and the progress_iterate elements.

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.

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.

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.

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.

PhpDirHandle recorded the opened path and nothing else, and its only
caller asked just whether the open had succeeded. A resource type that
has to gain readdir and closedir before it means anything is worse than
the std::fs::read_dir call it wraps, so Filesystem::isReadable now makes
that call directly.

The two TODOs marked deferred work that nothing reaches.
FILE_USE_INCLUDE_PATH appears nowhere in Composer or its vendored
dependencies, and the only site passing LOCK_EX to file_put_contents is
Symfony's Filesystem::appendToFile(), which no caller invokes and which
raises the flag only when handed a third argument. The stream $context
is dropped just as narrowly: the network scheme that would carry one is
already marked at the call site in RemoteFilesystem, leaving the shim
reachable through the local-file branch alone.
Record what these functions do and do not support instead, so the tags
stay a list of work that is actually pending.

The comment claimed the port loses the file type bits that PHP's
fileperms() reports. It does not: MetadataExt::mode() hands back the raw
st_mode, the same value php_stat() returns for FS_PERMS, and both agree
on directories, regular files and executables.

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.

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.

`http_build_query` ignores `numeric_prefix` because a string-keyed slice never
holds an integer key, and every caller passes `"&"` as the separator. Drop both
parameters and hard-code the separator.
Callers that pass a map of scalar literals to `http_build_query_mixed` no longer
need to build an `IndexMap<String, PhpMixed>` for it, so move them to the slice
form.

`http_build_query(['packages' => array_keys($packageConstraintMap)])` maps a
single array value, so the body PHP sends is `packages%5B0%5D=a&packages%5B1%5D=b`.
The port flattened the array into repeated `packages=<name>` pairs, losing the
indices, and passed `"&"` as the numeric prefix and `"="` as the argument
separator, joining every pair with `=`.
Build the query from a `packages` key holding the name list and hand it to
`http_build_query_mixed`, which walks the nested value.

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().

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.

`__halt_compiler` is a PHP keyword, so a stub may spell the token in any
letter case. The native phar reader compared the bytes exactly and rejected
such an archive, and the lint that keeps a second token out of the

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.

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.
