debuglock: make the command more useful in non-interactive mode The existing prompt mode simply release the lock immediately in non-interactive mode. That is quite useless in the test so now the non-interactive mode simply wait for a signal. Differential Revision: https://phab.mercurial-scm.org/D12616

auto-upgrade: add a test case with no permission to lock the repository This show the current behavior when the repository is unlockable. The current behavior is to abort, which is probably not great. Now that we have a proper test, we can think about the behavior we want in a later changeset.

auto-upgrade: introduce a way to auto-upgrade to/from dirstate-v2 This is similar to what we introduced for `share-safe`, but apply to the tracked-hint feature. Differential Revision: https://phab.mercurial-scm.org/D12614

upgrade: split some logic from UpgradeOperation The logic for automatic-upgrade and the upgrade-repo should be able to use the same code. However that code often need an UpgradeOperation object to function. So we start spliting the Operation into a minimal component that we will be able to reuse outside of the "classic" upgrade path. We will put the base-class to use in the next changeset. Differential Revision: https://phab.mercurial-scm.org/D12612

auto-upgrade: introduce a way to auto-upgrade to/from share-safe This is the first "automatic-upgrade" capability. In the following commits, similar features are coming for other "fast to upgrade" formats. This is different from the `safe-mismatch.source-not-safe` and `safe-mismatch.source-safe` configuration that deal with mismatch between a share and its share-source. Here we are dealing with mismatch between a repository configuration and its actual format. We will need further work for cases were the repository cannot be locked. A basic protection is in place to avoid a infinite loop for now, but it will get proper attention in a later changeset. Differential Revision: https://phab.mercurial-scm.org/D12611

clone: use better names for temp files Before this commit, the file names are /tmp/tmpn8smvlr8 After this commit, they are more like /tmp/hg-clone-n8smvlr8/00manifest.ndb3qj52v6, which makes it much clearer what these files correspond to.

copies-sdc: mark upgrade action as changelog only We don't need to recompute the other revlog to add the changelog-v2 feature. This simplify upgrade that use copies-sdc (as shown in the tests).

changelog-v2: mark upgrade action as changelog only We don't need to recompute the others revlog to add the changelog-v2 feature. This does not have much effect in practice as the `copies-sdc` upgrade still triggers the other revlogs. This will be fixed in the next changeset.

copies-sdc: no longer suppress the upgrade output To make sure the upgrade simplification we need are taken into account, we need to see more of the output of `debugupgraderepo`. The --quiet flag simplify the output a lot and globing the `preserved` field mean this output should remains stable across (future) unrelated changes.

copies-sdc: no longer use revlogv2 in `test-copies-in-changeset.t` We only need changelog-v2 and its usage is automatically inferred. So we can simplify the test by dropping this. This is important to test future simplification of the update process in the coming changesets.

fix-ci: backed out changeset 308e45f7b455 The chg variant of the CI see a failure on `tests/test-narrow-pull.t`. Bisecting point the failure as starting at this small changeset… Backing it out, restore the CI on default. It was never broken on stable, which is even more puzzling.

branching: merge stable into default

ci: do not trigger phabricator for merge-request The fast the phabricator steps has a `rules` entry makes it selected for the special `merge_requests` pipelines. The other ones behave as default and are not selected tot the mrege_request pipelines. This result in a second pipeline to be created, with only the phabricator pipeline in it. Which usually succeed fast (since there is nothing to do). This is harmful as this create a false sense of "the series is passing" and Gitlab will use this simplistic pipeline for validation. By explicitly preventing the pipeline to be created in the merge-request case, we prevent this situation to happens Note that the job will be dropped (alonside phabricator) in the next two weeks anyway.

branching: merge with stable

amend: stop specifying matcher, get all copies in wctx When we're recreating the commit that we'll be committing, we don't want to filter our copy information based on just the *new* [versions of the] files we're amending. The test has an example of this case, but for clarity, the situation is: ``` $ hg cp src dst && hg commit <do some work> $ hg amend some_unrelated_file.txt $ hg status --copies A dst A some_unrelated_file.txt ``` What *should* happen is that `dst` should remain marked as a copy of `src`, but this did not previously happen. `matcher` here only includes the files that were specified on the commandline, so it only gets the copy information (if any, in this example there's not) for `some_unrelated_file.txt`. When it goes to apply the memctx to actually create the commit, the file copy information is incomplete and loses the information for the files that shouldn't have been affected at all by the amend.

rust-repo: make `Send` by not storing functions in `LazyCell` We (Google) want to use `Repo` in a context where we can store it in `Mutex<Repo>`. However, that currently doesn't work because it's not `Send` because the `LazyCell` initialization functions are not `Send`. It's easy to fix that by passing them to the `get_or_init()` and `get_mut_or_init()` functions. We'll probably also want `Repo` to be `Send` (and even `Sync`) in core later, so this seems like a step in the right direction. Differential Revision: https://phab.mercurial-scm.org/D12582

node: manually implement Debug I got too irritated today with the default Debug implementation of hg::revlog::Node while playing with a new parser. This isn't quite what I wanted, but it wasn't much code and it at least gives you output that's easy to visually compare to a node.hex()ed identifier from the Python side of things. Sadly, this doesn't influence the output in lldb or the VSCode debugger extension that uses lldb under the covers, but it at least means debug prints are a little more useful.

censor: make rhg fall back to python when encountering a censored node This is to make it support censor.policy=ignore without having to duplicate that logic. Also, change the censor test in such a way that it uses rhg now, because extensions are disabled except when we call [hg censor]. Differential Revision: https://phab.mercurial-scm.org/D12607

followlines: don't put Unicode directly into the .js file (issue6559) Apparently some web server setups may serve this file in a different encoding than UTF-8, and that results in visual garbage in the followlines button that renders for every line in a file. So instead of using this Unicode character in UTF-8 we can encode it as \u2212. Or, to be more explicit, we can use &minus; HTML entity, which resolves into exactly that character. Since now we're using innerHTML property to set the minus part of the button, let's use it to set the plus part as well (even though the plus sign was plain ASCII). A wise man once said "A foolish consistency is the hobgob... eh, whatever." Throw a brick at me if this makes things worse. Differential Revision: https://phab.mercurial-scm.org/D12597
