tests: give more room for slowness in test-run-tests.t The test expected any run-test.py run to end in less than 10 seconds. On slower loaded CI machine, this gets slower than that. We give a bit more room to the regexp.

relnotes: copy "next" to "5.1" and clear "next" To avoid merge conflicts, we want to avoid modifying the file on multiple branches in parallel. This patch is therefore meant to be applied to the stable branch and then quickly be merged to default (at least before edits are made to relnotes/next there). Another option would have been to copy the file on the stable branch and to clear it on the default branch. However, that still results in conflicts if the copy is edited on the stable branch (Mercurial would try to apply the changes from the default branch to it). We could also delete the file in one commit and recreate it in another commit. However, Mercurial is quite inconsistent in what it considers a break in history (see test-copies-unrelated.t), so I'd like to avoid that. Differential Revision: https://phab.mercurial-scm.org/D6705

automation: push changes affecting .hgtags When I went to build the 5.1 tag using the in-repo automation, the automatic version calculation failed to deduce the clean 5.1 version string because we had only pushed the changeset corresponding to the 5.1 tag and not the changeset containing the 5.1 tag. So from the perspective of the remote repo, the 5.1 tag didn't exist yet and automatic version deduction failed. This commit changes the `hg push` to also push all changesets affecting the .hgtags file, ensuring the remote has up-to-date tags information. I tested this by creating a local draft changeset with a dummy tag value on a different DAG head and instructed the automation to build a revision that didn't have this change to .hgtags. The tag was successfully pushed and the built package had a version number incorporating that tag. Sending this to stable so the 5.1.1 automation hopefully "just works."

bookmarks: actual fix for race condition deleting bookmark This is a simple but efficient fix to prevent the issue tested in `test-bookmarks-corner-case.t`. It might be worth pursuing a more generic approach where filecache learn to depend on each other, but that would not be suitable for stable. The issue is complicated enough that I documented the race and its current solution as inline comment. See this comment for details on the fix.

strip: access bookmark before getting a reference to changelog Bookmark access might invalidate the current changelog (to make sure both are in a reasonable synchronisation state). So we should grab the reference to changelog after we access bookmark. Otherwise we risk using a dead object for the whole strip process. (note: this dead object business probably requires a new layers of checking)

test: use a more verbose output in the test While debugging some test failure, I released the test never checks if the relevant changesets were preserved. So I am updating the test from `hg parents` usage to `hg log -G` with a special template. This increase the area covered by the test and clarify the test failures.

Added signature for changeset e91930d712e8

Added tag 5.1 for changeset e91930d712e8

automation: execute powershell when connecting For some reason, the ability to execute PS scripts appears to come online after the ability to execute regular command scripts. This is creating race conditions when connecting to instances resulting in our wait_for_winrm() returning before PS is available leading to an exception being thrown in other code. Let's change the client connection code to execute a minimal PS script so we can try to trap the exception in wait_for_winrm().

automation: allow exit code of 1 for `hg push` `hg push` exits 1 for no-ops. No-op pushes should be fine in the context of automation.
