optimizations, hooks - #4
Conversation
…rtok bug tr_array полностью переведён на emalloc/erealloc/efree. Функции записи фиксированных типов перемещены в заголовок как static inline для устранения накладных расходов на вызов. tr_array_clear теперь только сбрасывает size/position без переаллокации. Исправлен порядок CHECK_ALLOC в init; tr_array_free обнуляет поля. Исправлена ошибка в parse_domain_port_pairs: strdup перед strtok, чтобы не модифицировать исходную строку. test.php разбит на четыре .phpt-теста (settings, timer, stress, tr_array_memory) и удалён. Добавлен C-юнит-тест для parse_domain_port_pairs (8 кейсов) и tr_internal_test (32 теста для tr_array и tr_timer) с заглушкой tests/stubs/php.h, позволяющей компиляцию вне PHP. CI обновлён для запуска make test и всех C-юнит-тестов.
The header did not use any types from zend.h, but its inclusion prevented standalone compilation of unit tests outside of a PHP extension build context.
The stub provides malloc-based substitutes for emalloc/erealloc/efree and a minimal zend_resource definition, allowing tr_internal_test to compile without real PHP headers.
- tests/install_test.sh verifies make install (checks .so exists, runs PHP smoke test) - Dockerfile: remove 'exit 1', fix build (make -j, no 'make clean' before install), add install_test verification - tests/.gitignore: allow *.sh scripts
- Function takes no arguments and returns nested array with camelCase keys - README quick start and function table corrected - install_test.sh assertions fixed to match real API
- send_data(): free strdup fallbacks for request_domain/request_uri
- send_data(): remove useless strdup("argv") leak
- update_server_list(): clean old collectors beyond new limit, NULL host after free
- tr_client_destroy(): socketFd >= 0 check (was > 0), NULL host after free
- find_domain_resolve_cache_lru_entry_index(): guard for empty cache
- parse_domain_port_pairs(): max_pairs size_t vs int signedness
- tests/udp_test_server.php: PHP-based UDP server that receives chunked packets, reassembles, and parses the binary protocol - Integrated into install_test.sh as step 4 (UDP integration test) - tests/.gitignore: allow *.php files
- INI: trochilidae.hook_list (comma-separated, supports function, Class->method, Class::method, Class.method) and trochilidae.debug (E_WARNING on miss) - tr_hooks_lazy_attach: parses hook_list once at first RINIT, replaces zend_function handlers with a generic bridge that collects call_count + total_time - tr_hooks_reset: zeroes counters per request - tr_hooks_serialize: appends hook metrics to UDP packet after timers section - Generic tr_hook_bridge handles all hooks via execute_data->func pointer comparison - Duplicate detection, skip uninstalled modules, debug warnings - utils.c: fix prng_seeded scope (static inside #else block)
- New INI with PHP_INI_ALL, validated in update_server_list after tr_client_init - Values < 22 or > 65507 revert to MAX_CHUNK_SIZE

Inline comments:
In @.github/workflows/opencode.yml:
- Around line 23-26: Update the actions/checkout step in the workflow to provide
an explicit ref for the pull request head, using the event’s PR head reference
so issue_comment and pull_request_review_comment runs check the PR code rather
than the default branch.
In `@Dockerfile`:
- Around line 125-131: Расширьте финальную проверку после сборки расширения в
цепочке RUN, где сейчас запускается tests/install_test.sh: добавьте выполнение
полного набора PHP .phpt-тестов, сетевых тестов и внутренних C-тестов, сохранив
существующий smoke-тест и сделав так, чтобы любой сбой останавливал сборку
Docker.
In `@tests/003_stress.phpt`:
- Around line 3-5: Добавьте в изолированный тест `tests/003_stress.phpt`
настройку `trochilidae.server_list=localhost` через стандартную секцию
конфигурации PHPT, сохранив существующие `SKIPIF` и `FILE` без изменений.
In `@tests/004_chunking.phpt`:
- Around line 15-16: Update the server_list value in the isolated test
configuration to use “localhost” instead of the loopback IP address, while
leaving the chunk_size setting unchanged.
In `@trochilidae/compat.h`:
- Around line 82-94: Update the lifecycle stubs in compat.h so PHP_MINIT,
PHP_MSHUTDOWN, PHP_RINIT, and PHP_RSHUTDOWN expand to Zend-compatible function
names rather than statement expressions, matching the callbacks used to
initialize zend_module_entry in trochilidae.c. Also make the ZEND_MODULE_*_N
return stubs use a defined standalone-compatible success value.
In `@trochilidae/tr_hooks.c`:
- Around line 24-33: Rename the internal C functions skip_spaces, trim_tail, and
build_hook_name to use the required tr_ prefix, updating every declaration and
call site while preserving behavior. Replace the php_error(E_WARNING, ...) calls
around the affected error paths with php_error_docref using the existing warning
messages and appropriate documentation context.
- Around line 86-97: Normalize hook function and class names to lowercase before
all zend_hash_str_find lookups in the hook resolution logic around e->type,
including EG(function_table), CG(class_table), and ce->function_table; preserve
the original names for other uses and ensure PDO->query and Redis->get resolve
regardless of input casing.
- Around line 8-22: Update the hook initialization path that replaces handlers
in RINIT so shared zend_function handlers are patched only once process-wide,
with synchronization for concurrent ZTS threads; keep per-thread TR_G(hooks),
hooks_attached, and hook_count state from recording tr_hook_bridge as
original_handler. Normalize names from hook_list to lower-case before
function_table/class_table lookup so hooks such as PDO::... and DateTime::...
resolve correctly.
In `@trochilidae/tr_network.c`:
- Around line 259-329: Ensure the non-retryable sendto failure path in
send_chunks releases the allocated packet buffer before returning -1. Preserve
the existing EAGAIN/EWOULDBLOCK handling and normal cleanup, while preventing
the fatal error branch from bypassing free(packet).
- Around line 180-198: Update tr_client_create to handle failure from
tr_client_set_addr_info by closing client->socketFd before returning false and
resetting the descriptor to its invalid state. Preserve the existing socket
cleanup behavior for successful address initialization and ensure no descriptor
remains open when address setup fails.

- Around line 24-34: Замените fallback-ветку функции generate_random_ulong,
использующую srand/rand и time/getpid, на криптографически стойкий системный

GitHub Actions issue_comment pull_request_review_comment GITHUB_REF default ref checkout behavior docs
💡 Result:
When using actions/checkout in GitHub Actions, the default behavior for the ref input is to check out the reference or SHA that triggered the workflow [1][2]. If no specific reference is provided by the triggering event, it falls back to the repository's default branch [1][2]. For events like issue_comment and pull_request_review_comment, GITHUB_REF does not point to the pull request branch by default [3][4]. Instead, these events typically result in GITHUB_REF pointing to the repository's default branch (or, in some configurations, a merge ref) [3][4]. Because actions/checkout uses GITHUB_REF by default, simply using the action without specifying a ref will generally check out the default branch rather than the pull request's code [5][4]. To check out the pull request code when triggered by issue_comment or pull_request_review_comment, you must manually resolve and pass the pull request's head branch or commit SHA to the ref input of actions/checkout [5][4]. A common pattern involves using actions/github-script to fetch the pull request details from the event payload and setting an output variable, which is then used as the ref in the checkout step [5]: - name: Get PR branch id: pr uses: actions/github-script@v7 with: script: | const { data: pr } = await github.rest.pulls.get({ owner: context.repo.owner, repo: context.repo.repo, pull_number: context.payload.issue.number }); core.setOutput('head_ref', pr.head.ref); - uses: actions/checkout@v4 with: ref: ${{ steps.pr.outputs.head_ref }} Always ensure that your workflow has the necessary permissions (e.g., contents: read and pull-requests: read) to access repository data and interact with the Pull Request API [5].

Блокировка расширения после фатальной ошибки (bailout).
Если выполнение прервется критической ошибкой Zend Engine (например, OOM или timeout) прямо во время работы send_data(), флаг TR_G(in_send_data) останется в состоянии true. В результате для всех последующих запросов, обрабатываемых этим же воркером, tr_reset() будет сразу возвращать FAILURE. Это приведет к тому, что метрики старого запроса не очистятся, а новая отправка данных будет навсегда заблокирована для этого потока.
Рекомендуется безусловно сбрасывать этот флаг перед проверкой (или делать это в PHP_RSHUTDOWN_FUNCTION).

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Valgrind-повтор не масштабирует таймауты/итерации CLI-запросов, что может маскировать искомый краш.
FCGI_TIMEOUT_SEC увеличен до 15с для FPM-стороны, но CLI_REQUESTS (по умолчанию 60) и CLI_TIMEOUT_SEC (по умолчанию 5с) не переопределены. Под valgrind --track-origins=yes каждая CLI-итерация может не укладываться в 5-секундный timeout, из-за чего run_cli_requests() завершится с "FAIL: CLI request failed" вместо диагностики реальной проблемы. Кроме того, при повторных запусках valgrind с одним и тем же --log-file=$VALGRIND_CLI_LOG предыдущий лог перезаписывается — из 60 итераций сохранится только последняя.

docker run --rm без монтирования тома теряет все артефакты дебага.
Контейнер запускается с --rm, а -v не задан. TMP_DIR (сохраняемый благодаря KEEP_TMP_DIR=1), полные valgrind-логи и найденные core* файлы существуют только внутри файловой системы контейнера и уничтожаются вместе с ним сразу после выхода. Наружу попадает лишь то, что успело напечататься в stdout (отфильтрованные rg-совпадения и вывод gdb), а не полные логи/core-файлы для повторного анализа.
