Each row stores: * The last SQL that actually belongs to the crash (from `$wpdb`, or from a small adapter when a plugin talks to MySQL outside `$wpdb`) * Memory usage, peak, and the configured limit * File and line * The plugin, theme, or core component most likely involved * The request URL Entries live in a dedicated table, under Tools Stack Trace. You can export CSV or clear the log. This is not a debug.log viewer and not a live profiler. Generic log plugins tail PHP or WordPress logs. Stack Trace records **why a request died**: the SQL that belongs to the crash (including plugins that never set `$wpdb->last_query`), memory at the limit, and exceptions another plugin caught so the site would not white-screen. Typical case: an All-in-One WP Migration export that fails with “refresh and try again” while the real cause is a 128M SELECT or a full disk. It is for the morning after: the site crashed, nobody was watching, and you want the cause. #### Plugins that bypass $wpdb Some exporters (All-in-One WP Migration among them) run SQL on `$wpdb->dbh` directly.` $wpdb->last_query` is then empty or already overwritten (cron, Action Scheduler). Stack Trace keeps SQL in memory via adapters and, on failure, can read that plugin’s own error-log `last_query` field. It does not edit third-party files and does not hook their export pipeline as a stage. #### Automatic update failure emails (WordPress 7.2+) A failed automatic plugin update already includes the fatal message, file, and line. Stack Trace adds memory and last SQL from the same loopback check, with a link to the full log. ## ການຕິດຕັ້ງ 1. Upload the `tlloancy-stack-trace` folder to `/wp-content/plugins/`. 2. Activate the plugin from the Plugins screen. 3. Open the log under Tools Stack Trace. ## ຄຳຖາມທີ່ພົບເລື້ອຍ ### Does this slow the site down? On a normal request the cost is a shutdown callback that returns immediately unless PHP reports a fatal. A row is written only when something is recorded. Adapters add work only for the target plugin’s AJAX (for example an All-in-One export hop): a header check on success, disk I/O only on failure. ### How many entries are kept? 300 by default. Older rows are pruned when you open the admin page. Override the limit with `TLLST_MAX_ENTRIES` in wp-config.php. ### Does the plugin change other plugins’ files? No. It does not reorder `active_plugins` and it does not patch files on disk. ### Why is the last SQL not always from $wpdb? If the crash is inside a known custom MySQL client, `$wpdb->last_query` is often unrelated. The adapter’s in-memory SQL (or that plugin’s error log) is used instead. ## ການຣີວິວ ບໍ່ມີການຣີວິວສຳລັບປລັກອິນນີ້. ## ຜູ້ຮ່ວມພັດທະນາ ແລະ ຜູ້ພັດທະນາ “TLloancy Stack Trace” ແມ່ນຊອຟແວໂອເພັນຊອດ (Open Source). ບຸກຄົນຕໍ່ໄປນີ້ໄດ້ມີສ່ວນຮ່ວມ ໃນການພັດທະນາປລັກອິນນີ້. ຜູ້ຮ່ວມພັດທະນາ * [ Thomas Lloancy ](https://profiles.wordpress.org/tlloancy/) [ແປ “TLloancy Stack Trace” ເປັນພາສາຂອງເຈົ້າ.](https://translate.wordpress.org/projects/wp-plugins/tlloancy-stack-trace) ### ສົນໃຈຮ່ວມພັດທະນາບໍ່?
