From 2df613048d8e7a1b1b9328551651256618477931 Mon Sep 17 00:00:00 2001 From: German <28149841+germa89@users.noreply.github.com> Date: Fri, 12 Jul 2024 18:14:13 +0200 Subject: [PATCH] fix: pool issues (#3266) * feat: adding port to exception message * fix: attempt tests before being ready * feat: changing arguments order * chore: wait for complete exit * test: raise exception if mapdl instances are alive between tests * chore: adding changelog file 3257.added.md * fix: adding missing import * fix: adding missing object * test: check process status * fix: running process check only on local. * feat: enforcing having exactly the amount of instances specified. Adding timeout to check if the instance is already launched. * feat: adding a timeout before moving on * fix: latest_version env var * feat: added pool_creator fixture. We use pool fixture to check pool health. fix: some tests * fix: NoSuchProcess error. Small cosmetic fix * chore: adding changelog file 3266.fixed.md * chore: adding changelog file 3266.fixed.md * refactor: small reog * test: activating previously skipped tests * fix: test * fix: adding port to avoid port collision * fkix: tests * docs: adding comments * feat: adding ``ready`` property and ``wait_for_ready`` method. fix: Making sure we restart the instance on the same path. refactor: waiting for the instance to get ready. test: added test to check directory names when there is a restart. * feat: Checking ports from the cmdline * fix: tests * fix: early exit in process check to avoid accessdenied. * Revert "fkix: tests" This reverts commit d58971bd5886d1db31313f295524cfea47c98904. * feat: catching already dead process. * fix: pymapdl list not showing any instance because name method wasn't called. * feat: wrapping process checking in a try/except to avoid calling already dead process * feat: using dynamic port in test_cli. Starting and stopping another instance. * fix: test * refactor: reducing code duplicity * feat: making sure we stop MAPDL if failure * fix: test_remove_temp_dir_on_exit on windows * test: without rerun * ci: using v24.2 for docs building * fix: exception in list instance processing * feat: using PORT1 variable refactor: moving console test to test_console * fix: tests * ci: run all tests * test: testing * test: no raise exception. * ci: increasing timeout for local and min jobs * chore: adding logging statements. * test: marking tests as xfail * ci: adding back pytest config * Revert "build: update ansys-api-mapdl to 0.5.2 (#3255)" This reverts commit 0bcf3447450aadca203228265b22df2504b4d18e. * test: skip flaky tests * build: update ansys-api-mapdl to 0.5.2 (#3255) * build: update ansys-api-mapdl to 0.5.2 * chore: adding changelog file 3255.dependencies.md --------- Co-authored-by: pyansys-ci-bot <92810346+pyansys-ci-bot@users.noreply.github.com> * test: skip flaky test.
