strip: invalidate phase cache after stripping changeset (issue5235)...
strip: invalidate phase cache after stripping changeset (issue5235) When we remove a changeset from the changelog, the phase cache must be invalidated, otherwise it could refer to changesets that are no longer in the repo. To reproduce the failure, I created an extension querying the phase cache after the strip transaction is over. To do that, I stripped two commits with a bookmark on one of them to force another transaction (we open a transaction for moving bookmarks) after the strip transaction. Without the fix in this patch, the test leads to a stacktrace showing the issue: repair.strip(ui, repo, revs, backup) File "/Users/lcharignon/facebook-hg-rpms/hg-crew/mercurial/repair.py", line 205, in strip tr.close() File "/Users/lcharignon/facebook-hg-rpms/hg-crew/mercurial/transaction.py", line 44, in _active return func(self, *args, **kwds) File "/Users/lcharignon/facebook-hg-rpms/hg-crew/mercurial/transaction.py", line 490, in close self._postclosecallback[cat](self) File "$TESTTMP/crashstrip2.py", line 4, in test [repo.changelog.node(r) for r in repo.revs("not public()")] File "/Users/lcharignon/facebook-hg-rpms/hg-crew/mercurial/changelog.py", line 337, in node return super(changelog, self).node(rev) File "/Users/lcharignon/facebook-hg-rpms/hg-crew/mercurial/revlog.py", line 377, in node return self.index[rev][7] IndexError: revlog index out of range The situation was encountered in inhibit (evolve's repo) where we would crash following the volatile set invalidation submitted by Augie in e6f490e328635312ee214a12bc7fd3c7d46bf9ce. Before his patch the issue was masked as we were not accessing the phasecache after stripping a revision. This bug uncovered another but in histedit (see explanation in issue5235). I changed the histedit test accordingly to avoid fixing two things at once.

Requirements
============
Repositories contain a file (``.hg/requires``) containing a list of
features/capabilities that are *required* for clients to interface
with the repository. This file has been present in Mercurial since
version 0.9.2 (released December 2006).
One of the first things clients do when opening a repository is read
``.hg/requires`` and verify that all listed requirements are supported,
aborting if not. Requirements are therefore a strong mechanism to
prevent incompatible clients from reading from unknown repository
formats or even corrupting them by writing to them.
Extensions may add requirements. When they do this, clients not running
an extension will be unable to read from repositories.
The following sections describe the requirements defined by the
Mercurial core distribution.
revlogv1
--------
When present, revlogs are version 1 (RevlogNG). RevlogNG was introduced
in 2006. The ``revlogv1`` requirement has been enabled by default
since the ``requires`` file was introduced in Mercurial 0.9.2.
If this requirement is not present, version 0 revlogs are assumed.
store
-----
The *store* repository layout should be used.
This requirement has been enabled by default since the ``requires`` file
was introduced in Mercurial 0.9.2.
fncache
-------
The *fncache* repository layout should be used.
The *fncache* layout hash encodes filenames with long paths and
encodes reserved filenames.
This requirement is enabled by default when the *store* requirement is
enabled (which is the default behavior). It was introduced in Mercurial
1.1 (released December 2008).
shared
------
Denotes that the store for a repository is shared from another location
(defined by the ``.hg/sharedpath`` file).
This requirement is set when a repository is created via :hg:`share`.
The requirement was added in Mercurial 1.3 (released July 2009).
dotencode
---------
The *dotencode* repository layout should be used.
The *dotencode* layout encodes the first period or space in filenames
to prevent issues on OS X and Windows.
This requirement is enabled by default when the *store* requirement
is enabled (which is the default behavior). It was introduced in
Mercurial 1.7 (released November 2010).
parentdelta
-----------
Denotes a revlog delta encoding format that was experimental and
replaced by *generaldelta*. It should not be seen in the wild because
it was never enabled by default.
This requirement was added in Mercurial 1.7 and removed in Mercurial
1.9.
generaldelta
------------
Revlogs should be created with the *generaldelta* flag enabled. The
generaldelta flag will cause deltas to be encoded against a parent
revision instead of the previous revision in the revlog.
Support for this requirement was added in Mercurial 1.9 (released
July 2011). The requirement was disabled on new repositories by
default until Mercurial 3.7 (released February 2016).
manifestv2
----------
Denotes that version 2 of manifests are being used.
Support for this requirement was added in Mercurial 3.4 (released
May 2015). The requirement is currently experimental and is disabled
by default.
treemanifest
------------
Denotes that tree manifests are being used. Tree manifests are
one manifest per directory (as opposed to a single flat manifest).
Support for this requirement was added in Mercurial 3.4 (released
August 2015). The requirement is currently experimental and is
disabled by default.
