revlog: fix descendant deprecated method Fix the descendant deprecated method introduced earlier in this cycle. This was caught by Yuya, thank you.

ui: remove commands.status.terse=u from ui.tweakdefaults commands.status.terse=u can add significant overhead when operating on large repositories. Using the Firefox repository: HGRCPATH= hg --time status time: real 1.340 secs (user 0.960+0.000 sys 0.380+0.000) HGRCPATH= hg --time --config commands.status.terse=u status time: real 2.420 secs (user 2.070+0.000 sys 0.360+0.000) HGRCPATH= hg --time --config extensions.fsmonitor= status time: real 0.080 secs (user 0.050+0.010 sys 0.040+0.000) HGRCPATH= ~/src/hg/hg --time --config extensions.fsmonitor= --config commands.status.terse=u status time: real 2.470 secs (user 2.080+0.000 sys 0.390+0.000) The performance regression - especially when fsmonitor is being used - is too much to stomach for the 4.7 release. We've decided to remove commands.status.terse=u from ui.tweakdefaults until we can improve its performance, hopefully in the 4.8 cycle. This commit effectively backs out 6acf41bb8d40.

context: safegaurd against 'lx' being passed as file flag in manifest Subversion can have a file as executable link. When using hgsubversion, we will have both islink and isexec True. This will lead to _flags being set to `lx`. However, manifest expects flag to be one-byte so it will crash if 'lx' is passed. Also it's impossible to have an executable link. This patch will safegaurd us from having 'lx' being a possible value. This was authored by Ivan Lezhankin from Yandex. Differential Revision: https://phab.mercurial-scm.org/D3985

localrepo: unconditionally enable general delta with sparse revlogs This come as an extra security, better safe than sorry.

sparse-revlog: also use sparse-revlog config as a general delta trigger Sparse revlog rely on general delta, so we should make sure it is used.

fileset: suppress EACCES while reading arbitrary paths via filectx API On Windows, EACCES is raised in place of EISDIR. This patch simply adds EACCES to the list of errors to be ignored since I think it's okay for filesets to treat inaccessible working-copy files as not existing.

merge: do the trivial resolution after updating sparse checkout In merge, we do trivial resolution for files which were deleted on one side and changed on other. When sparse extension in involved that file might not be present in wdir and trivial resolution can lead to file not found error. This patch make sure we updates the sparse checkout before doing the trivial resolution. This fixes the test failure demonstrated in previous patch.

sparse: add test showing `hg merge` is broken while using sparse extension This patch adds a test to demonstrate that `hg merge` is broken in some cases while using sparse extension. The case is when you have a file which is: * modified between current wdir parent and merge base * deleted between merge base and merge destination * excluded from sparse checkout Doing `hg merge` results in file not found error. Next patch will fix this. Differential Revision: https://phab.mercurial-scm.org/D3983

context: use hex nodeid in error about filtered node I went a little too far in my cleanup in 9231148ea599 (context: convert to hex for error message only for 20-byte changeid, 2018-04-06). I missed that the case where a binary nodeid refers to a filtered node. Differential Revision: https://phab.mercurial-scm.org/D3987

doc: fix underline length for config title (issue5949) This was an error in the initial commit. Thanks go to Marcel Svitalský for reporting the bug.
