az postgres flexible-server maintenance-event list

Description

az postgres flexible-server maintenance-event list always failed with TypeError: flexible_server_maintenance_event_list() got an unexpected keyword argument 'ids', regardless of which arguments were passed.

Root cause: server_name was registered with id_part='name' in the maintenance-event list argument context. This causes azure-cli-core to auto-register a --ids argument for the command. The existing c.ignore('ids') call was not sufficient to suppress this, since the ids-argument wiring is independent of ignore and still routes an ids value into the custom command handler, which does not accept that kwarg.

  • Set id_part=None on server_name for the maintenance-event list argument context, so the auto-ids logic no longer attaches an ids argument to this command (matches the existing pattern used in other modules, e.g. appservice).
  • Added a regression unit test asserting the ids-ignore configuration for this command.

Testing Guide

az postgres flexible-server maintenance-event list --resource-group <rg> --server-name <server>

Previously this failed immediately with the TypeError above during argument parsing. After the fix, the command proceeds normally to the service call.

CI and Live-Test Failures — Action Required

Two issues were found and must be fixed:


1. ❌ PR Title Format (ADO pipeline: Check the Format of Pull Request Title and Content — 3 errors)

The current PR title uses {PostgreSQL} (curly braces = non-customer-facing) but the PR also adds an entry to HISTORY.rst, which is only correct for customer-facing changes ([Component] square-bracket format). This mismatch causes the format gate to fail.

Use this EXACT PR title (copy verbatim):

[Postgresql] Fix #33846: `az postgres flexible-server maintenance-event list`: fix TypeError caused by unsupported --ids argument

Also ensure the PR description includes Fixes #33846 and follows the PR template.

PR title & description format (required)

This repo enforces a PR format (guide). Please author the PR exactly as follows or CI's Check the Format of Pull Request Title and Content will fail.

Use this EXACT PR title (copy verbatim, do not reword):

[Postgresql] Fix #33846: `az postgres flexible-server maintenance-event list`: fix TypeError caused by unsupported --ids argument

Keep the backticks around the command and the Fix #33846: prefix. You may only adjust the wording after the command (the final summary) if the fix changes; the [Postgresql] prefix, issue link, and backticked command must stay.

Description — follow the PR template and fill in:

  • Link the issue — start the Description with a closing keyword so the PR auto-links and closes it: Fixes #33846.
  • Related command — the az ... command this affects.
  • Description (mandatory) — why the bug happens, what you changed, and the resulting behavior.
  • Testing Guide — example command(s) showing the fix works.
  • History Notes — leave the title to drive the history note, or add extra lines in the same format (component in brackets + the command in backticks), e.g. [Postgresql] `az <command>`: <note>.
  • Keep the template checklist and tick the items you've satisfied.

2. ❌ Live Test: azdev selected 0 tests (test file not in tests/latest/)

The new test file was placed at:

src/azure-cli/azure/cli/command_modules/postgresql/tests/unit/test_maintenance_event_params.py

azdev test only discovers tests under tests/latest/, not tests/unit/. The live-test workflow failed because azdev could not find any test to run from the changed files.

Fix: Move the test file to tests/latest/:

src/azure-cli/azure/cli/command_modules/postgresql/tests/latest/test_maintenance_event_params.py

The test itself only registers argument behavior and does not need live Azure resources, so it will run fine as a unit-style test inside the tests/latest/ directory.
