Concurrent package operations call into the same downloader instances
through Rc<RefCell<dyn DownloaderInterface>>; with &mut self methods
every call holds a RefMut across its awaits, which panics with
'already mutably borrowed' the moment two operations overlap. This is
groundwork for fanning out InstallationManager's download/install
loops (same rework HttpDownloader/CurlDownloader already got).
- DownloaderInterface/ChangeReportInterface/ArchiveDownloader/
VcsDownloader methods now take &self; as_change_report_interface
returns &dyn instead of &mut dyn.
- Implementors move their genuinely mutable state behind cells:
FileDownloader.additional_cleanup_paths, the archive downloaders'
cleanup_executed, ZipDownloader.zip_archive_object,
VcsDownloaderBase.has_cleaned_changes, GitDownloader's stash/discard/
cache maps and GitUtil, SvnDownloader.cache_credentials,
PerforceDownloader.perforce. FileDownloader.io gains a RefCell layer
so get_local_changes can keep PHP's NullIO swap under &self.
- ProcessExecutor::execute_async now returns a future that captures
everything up front instead of borrowing the executor, and call
sites build the future before awaiting, so no borrow on the shared
executor is held while a subprocess runs.
- Filesystem::remove_directory_async becomes remove_directory_async_via
taking the Rc handle: the Filesystem is only borrowed for the sync
head/tail, never across the rm subprocess await (sync borrow_mut
users like rename/ensure_directory_exists would otherwise collide).
- DownloadManager async call sites hold shared borrows only.

execute_async was a serial pump: it queued a job, then drove it to
completion itself via wait_id()'s blocking usleep loop before
returning, so concurrent callers never overlapped even when polled
together through FuturesUnordered.
Rewrite it as a single &self async fn mirroring the CurlDownloader/
HttpDownloader rework: a tokio Semaphore sized by max_jobs
(COMPOSER_MAX_PARALLEL_PROCESSES, PHP parity) gates admission, the
child is started non-blocking, and an async 1ms sleep loop pumps
is_running()/check_timeout() while yielding to the reactor so sibling
jobs genuinely run in parallel. The Job table, STATUS_* lifecycle,
start_job/mark_job_done/count_active_jobs/wait/wait_id all had no
remaining callers and are removed.
&self also lets callers hold only a shared borrow across their awaits
(zip_downloader, version_guesser, filesystem via the new
get_process_handle), which would otherwise panic with 'already
mutably borrowed' once two async jobs overlap on the same
Rc<RefCell<ProcessExecutor>>.
The async mock branch no longer consumes the expectation before
hitting its todo!(): the panic made that bookkeeping unobservable.

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

Port 11 categories of previously-ignored Composer tests now reachable with
the mockall crate: DownloadManager, VCS/Perforce/File downloaders,
VersionSelector, PlatformRepository, Auditor, installer/FilesystemRepository,
RootPackageLoader, util auth/http, commands, and Cache.
Extract test seams additively on concrete structs as *Interface traits
(Runtime, HhvmDetector, VersionGuesser, RepositorySet, Perforce,
BinaryInstaller) plus mock-field seams (Cache, Filesystem); consumers take
trait objects. Mocks are defined locally in the test crates via
mockall::mock!, since automock-generated mocks are cfg(test)-gated and
invisible across the integration-test boundary.
dataProviders are ported in full; tests blocked by unported shims stay
#[ignore] with documented reasons rather than reduced or weakened.
Fix product bugs surfaced by the ports:
- util/github: use the exception code, not the HTTP status, for 401/403
- advisory: serialize empty audit maps as [] to match PHP json_encode
- repository/filesystem and downloader/file: fix RefCell double-borrow panics

Replace the Option<&mut PhpMixed> output plumbing with the IntoExecOutput
trait modelling each PHP `$output` case (forward, capture-to-buffer,
discard, callback). This lets do_execute pass a real output handler to
Process::run, captures output back via get_output, and lets Svn pass its
streaming filter handler through execute instead of skipping it.
|

Replace the generic cwd parameter backed by the IntoExecCwd trait with a
concrete Option<&str> across execute/execute_args/execute_tty/execute_async.

Redesign PhpResource into a real stream handle (File/Memory backing with
tracked position, eof, closed state) and unify the whole fopen family
(fopen/fwrite/fread/fgets/fgetc/feof/fclose/ftell/fseek/rewind/fstat/
ftruncate/fflush and stream_get_contents/stream_copy_to_stream) on
&PhpResource, replacing the split PhpMixed/PhpResource APIs and their
todo!() stubs. fopen now returns Result; read functions stay String for
now (TODO(phase-e) to move to byte strings).
Propagate the signatures through callers: Process stdout/stderr, Cursor
input, curl header/body handles (extracted into typed maps keyed by job
id), Filesystem copy/safe_copy/files_are_equal, BufferIO, error_handler,
platform, perforce, zip. The proc_open pipe paths cannot carry a
PhpResource in a PhpMixed list, so they are left as todo!() with notes.

PHP's internal array pointer (current/key/end) has no clean Rust
equivalent. Remove these todo!() shim stubs and replace each call
site with direct first/last element access matching Composer's
original behavior. Unblocks Config::merge of anonymous {name: false}
disable entries, re-enabling test_add_packagist_repository.

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.

The List and Array variants of PhpMixed boxed their elements
unnecessarily. Store PhpMixed values directly and update all callers
accordingly.

The Preg methods panic on PCRE failure (per the file header rationale),
so their anyhow::Result wrappers never carried an Err.

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.

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.

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.

RecursiveDirectoryIterator construction can throw UnexpectedValueException;
the shim now returns a Result so remove_directory_php can re-create the
iterator once after clearstatcache()/usleep, mirroring Composer's retry
for the spurious failures in composer/composer#4009.

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.

Mechanically convert promise-returning function bodies to async/await:
resolve() returns the value directly, forwarding calls get .await, and
simple .then chains become await sequences. Also collapse the installer
double-Option (Result<Option<Option<PhpMixed>>> -> Result<Option<PhpMixed>>).
Hard spots that depend on the Loop::wait / job-machine boundary
(accept/reject orchestration, closures capturing &mut self, batch waits)
are left intact and marked with TODO(phase-c-promise) for manual porting.
The crate does not compile yet; traits still need #[async_trait].
