This gives the repository control over which nested repository paths
that should be allowed via the custom path auditor.
Since paths into subrepositories are now allowed, dirstate.walk must
now filter away more paths than before.
When the filesystem cannot handle the executable bit, we currently
ignore it completely when looking for modified files. Similarly, it is
impossible to set or clear the bit when the filesystem ignores it.
This patch makes Mercurial treat symbolic links the same way.
Symlinks are a little different since they manifest themselves as
small files containing a filename (the symlink target). On Windows,
these files show up as regular files, and on Linux and Mac they show
up as real symlinks.
Issue1888 presents a case where the symlink files are better ignored
from the Windows side. A Linux client creates symlinks in a working
copy which is shared over a network between Linux and Windows clients.
The Samba server is helpful and defererences the symlink when the
Windows client looks at it. This means that Mercurial on the Windows
side sees file content instead of a file name in the symlink, and
hence flags the link as modified. Ignoring the change would be much
more helpful, similarly to how Mercurial does not report any changes
when executable bits are ignored in a checkout on Windows.
An initial checkout of a symbolic link on a file system that cannot
handle symbolic links will still result in a regular file containing
the target file name as its content. Sharing such a checkout with a
Linux client will not turn the file into a symlink automatically, but
'hg revert' can fix that. After the revert, the Windows client will
see the correct file content (provided by the Samba server when it
follows the link on the Linux side) and otherwise ignore the change.
Running 'hg perfstatus' 10 times gives these results:
Before: After:
min: 0.544703 min: 0.546549
med: 0.547592 med: 0.548881
avg: 0.549146 avg: 0.548549
max: 0.564112 max: 0.551504
The median time is increased about 0.24%.
The dirstate.granularity configuration parameter was never documented,
it only adds code complexity and it is unneeded.
Adding comments describing forced 'unset' entries.
This change narrows the race guard that was introduced by ffd022830d6d
("dirstate: ignore stat data for files that were updated too recently")
to not discard the _map entry's stat data if the mtime is in the future.
Without this change, status locks files having odd mtimes in the future
into the 'unset' state, causing needless file compares later (admittedly
harmless), but also inflicting highly irritating sticky effects on
tools/plugins that directly read .hg/dirstate (e.g. TortoiseHg).
Bound methods hold a reference to self, so assigning a bound method to
an instance unavoidably creates a cycle. Work around this by choosing
a normalize method at walk time instead. Eliminate default arg while
we're at it.
- merge always and match with patterns
- make always and match with patterns the default
- invert dostep3 to skipstep3
- move dirignore test inside exact case
nothing will ever match on match.never
nothing new will match on match.exact (all found in step 1)
nothing new will match on match.match when
there is no pattern and
there is no direcory in pats
Copy information was saved in a common loop, then refined in a git-only block.
The problem was the latter did filter out renames occuring in the current
patch and irrelevant to commit. In the non-git case, copy records still existed
in the dirstate, referencing removed files, making the commit to fail. Git and
non-git copy handling paths are now separated for simplicity.
