* libbacktrace abbrev cachedenkitaev4 days2-8/+296
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | ### Проблема libbacktrace парсит DWARF abbrev-таблицу заново для каждого CU — кэша по offset в build_address_map нет. Инструменты, дедуплицирующие .debug_abbrev между CU (llvm-bolt --update-debug-sections, dwz, -flto=full), сводят все таблицы к одной общей, на которую ссылаются все CU разом - и стоимость инициализации символизатора становится O(N_CU × размер общей таблицы). На BOLT-бинаре yabs-server (\~70k CU) первый же резолв бэктрейса разворачивает в память 70 тысяч копий одной и той же таблицы: 15.7 ГиБ анонимной памяти, в проде - OOM-цикл сервиса при включённой DWARF-символизации. Дедупликация таблиц есть и без BOLT (линкер мёржит одинаковые), поэтому эффект, в меньшем масштабе, заметен везде. ### Воспроизведение <https://nda.ya.ru/t/L_uavEhP7jBnqo> ```bash cd junk/denkitaev/libbacktrace_debug/repro ya make -r && ./repro # .debug_abbrev не дедуплицированна ya make -r -DUSE_LTO=yes && ./repro # .debug_abbrev дедуплицированна ``` ### Фикс Кэш распарсенных таблиц по abbrev_offset внутри build_address_map: таблица парсится один раз, CU получают shallow-копии. Кэш локален для одного вызова (одна .debug_abbrev-секция; потокобезопасность не меняется), владеет таблицами; fail-путь освобождает их ровно один раз — прежний per-unit free_abbrevs при шаринге дал бы double-free. Горячий путь резолва не тронут. #| || **<a href="https://nda.ya.ru/t/s7nuA8_37jBnqq" target="_blank">![](https://nda.ya.ru/t/mAiQIjHx7Mm3JC =30x) Echo tests</a>** || |# commit_hash:d101e82766f99efbc214a894c1e0971822ba0485
