tests: increase memory limit for snapd during the tests to 200M
Tests are flaky with the MemoryMax=150M, we saw recently failures around e.g.the `tests/main/microk8s-smoke:edge` test, e.g.: ``` 2023-09-06T07:36:43.0524017Z [ 560.495582] snapd invoked oom-killer: gfp_mask=0x101cca(GFP_HIGHUSER_MOVABLE|__GFP_WRITE), order=0, oom_score_adj=-900 ``` Lets increase the memory limit to make things less flaky.
tests: fix system-usernames-missing-user multiline MATCH
This test failed with: ``` 2023-09-05T12:51:25.0650751Z + echo 'Then the snap cannot be installed' 2023-09-05T12:51:25.0651128Z Then the snap cannot be installed 2023-09-05T12:51:25.0651591Z + MATCH 'cannot add user/group "snap_daemon": group exists and user does not' 2023-09-05T12:51:25.0652024Z + snap install --edge test-snapd-daemon-user 2023-09-05T12:51:25.0652503Z grep error: pattern not found, got: 2023-09-05T12:51:25.0653135Z error: cannot install "test-snapd-daemon-user": cannot ensure users for snap 2023-09-05T12:51:25.0653797Z "test-snapd-daemon-user" required system username "snap_daemon": cannot 2023-09-05T12:51:25.0654381Z add user/group "snap_daemon": group exists and user does not ``` This is because of the line breaks that are added in the error and that MATCH only matces a single line. This commit fixes it by changing the \n to normal spaces in the error message before doing the match.
o/servicestate,wrappers: disable support for activation mechanisms
Implement support for disabling activation mechanisms (timer, socket), and correctly report the status of services that are service-activated. The spread test for socket-activation services has been extended to not
Resealing can take more than a minute since it must hash a lot of files that it might need to unpack from snaps. It also needs to interact with the TPM and parse the event log, which might be slow. If we keep the lock, then snapd will not respond for a long time.
This fixes failures for `tests/nested/manual/core20-remodel`
