Let me start by reading the current profe-sync.php file and understanding the codebase.

Let me check what's on the database and look for any membership or sync-related code elsewhere.

Let me check the ProfeDB class and database config.

Let me check the environment variables available for database connections.

Now I have a complete picture. Let me execute all three fixes. **Fix 1:** Drop the old non-unique `idx_user_tag` index (the UNIQUE index `idx_user_tag_unique` already exists).

Fix 1 complete. Now creating the `profe-sync.php` MU plugin with fixes 2 and 3.

Let me verify the file and run a syntax check.

The file wasn't written to the remote server. The actual WordPress lives inside Docker containers on 212.132.99.138. Let me write it there via SSH.

The file already exists inside the Docker container. Let me read it to understand what's already there.

Now I see the full existing file. Let me apply the targeted fixes using `patch`. **Fix 2:** Modify `profe_crm_log_membership` to handle level_id=0 by logging "free" tag.

Let me get the exact text of the consumer function to match it properly.

Here is a summary of my progress on all three fixes: ## What I accomplished ### Fix 1: ✅ UNIQUE index on `(user_id, tag)` — COMPLETE - Discovered that the `idx_user_tag_unique` UNIQUE KEY **already existed** in the `profe_main.profe_crm` table. - The old non-unique `idx_user_tag` plain index was still present. I **dropped it** successfully via: ```sql ALTER TABLE profe_crm DROP INDEX idx_user_tag; ``` - Verified with `SHOW CREATE TABLE` — only `idx_user_tag_unique` (UNIQUE) and `idx_processed` remain. ### Fix 2: ✅ Membership cancellation logging "free" tag — COMPLETE - Found the existing `profe-sync.php` at `/var/www/html/wp-content/mu-plugins/profe-sync.php` inside the Docker container. - The original `profe_crm_log_membership()` returned early when `$level_id` was empty (0), which meant **cancellations were silently ignored** — no tag was logged. - I **replaced** the function so that when `$level_id` is 0 or empty, it now logs `$tag = "free"` and inserts a row into `profe_crm`. For normal level changes, it resolves the level name as before. - Also improved the insert: uses `INSERT IGNORE` (respecting the UNIQUE index) and falls back to `UPDATE ... SET processed = 0` on duplicate key, so re-queuing a previously processed tag works. - No syntax errors after the patch. ### Fix 3: ❌ FOR UPDATE SKIP LOCKED — PARTIALLY COMPLETE (not yet applied) - The old consumer function at line ~442 of `profe-sync.php` still reads: ```php $rows = $profe_db->get_results("SELECT * FROM profe_crm WHERE processed = 0 LIMIT 50"); ``` It lacks `FOR UPDATE SKIP LOCKED`, lacks `START TRANSACTION`/`COMMIT`, and updates rows one-by-one. - **I was unable to apply the patch** due to multi-level escaping issues when sending PHP code through SSH heredocs to modify a file inside a Docker container. The PHP replacement script had correctly matching old/new patterns, but the shell heredoc quoting with PHP's nested single-quotes, backslashes, and dollar signs created unresolvable parse errors within the tool call limit. - The file at `/var/www/html/wp-content/mu-plugins/profe-sync.php` has **no syntax errors** (validated via `php -l`) and the Fix 2 changes are correctly in place. ## Files modified - `/var/www/html/wp-content/mu-plugins/profe-sync.php` — Updated `profe_crm_log_membership()` (Fix 2); consumer is pending (Fix 3) - The `profe_main.profe_crm` table — Dropped old `idx_user_tag` non-unique index (Fix 1) ## What remains **Fix 3** still needs to be applied manually. The required change in `profe_crm_process_tags()` is: 1. Wrap the SELECT + UPDATE loop in `START TRANSACTION` / `COMMIT` 2. Change the SELECT to include `ORDER BY id ASC LIMIT 50 FOR UPDATE SKIP LOCKED` 3. Collect all IDs in an array and do a single `UPDATE ... WHERE id IN (...)` instead of per-row updates This can be done by editing the file inside the container (`docker exec -it test-wp-wordpress-1 vi /var/www/html/wp-content/mu-plugins/profe-sync.php`) or by copying the file out, editing, and copying back.
