global: use pycompat.xrange() On Python 3, our module importer automatically rewrites xrange() to pycompat.xrange(). We want to move away from the custom importer on Python 3. This commit converts all instances of xrange() to use pycompat.xrange(). Differential Revision: https://phab.mercurial-scm.org/D4032

pycompat: add xrange alias for Python 2 We assign xrange on Python 3 but not Python 2. Adding the missing symbol on Python 2 allows us to use `pycompat.xrange` to get a generator range function. Differential Revision: https://phab.mercurial-scm.org/D4031

manifest: persist the manifestfulltext cache Reconstructing the manifest from the revlog takes time, so much so that there already is a LRU cache to avoid having to load a manifest multiple times. This patch persists that LRU cache in the .hg/cache directory, so we can re-use this cache across hg commands. Commit benchmark (run on Macos 10.13 on a 2017-model Macbook Pro with Core i7 2.9GHz and flash drive), testing without and with patch run 5 times, baseline is r2a227782e754: * committing to an existing file, against the mozilla-central repository. Baseline real time average 1.9692, with patch 1.3786. A new debugcommand "hg debugmanifestfulltextcache" lets you inspect the cache, clear it, or add specific manifest nodeids to it. When calling repo.updatecaches(), the manifest(s) for the working copy parents are added to the cache. The hg perfmanifest command has an additional --clear-disk switch to clear this cache when testing manifest loading performance. Using this command to test performance on the firefox repository for revision f947d902ed91, whose manifest has a delta chain length of 60540, we see: $ hg perfmanifest f947d902ed91 --clear-disk ! wall 0.972253 comb 0.970000 user 0.850000 sys 0.120000 (best of 10) $ hg debugmanifestfulltextcache -a `hg log --debug -r f947d902ed91 | grep manifest | cut -d: -f3` Cache contains 1 manifest entries, in order of most to least recent: id: 0294517df4aad07c70701db43bc7ff24c3ce7dbc, size 25.6 MB Total cache data size 25.6 MB, on-disk 0 bytes $ hg perfmanifest f947d902ed91 ! wall 0.036748 comb 0.040000 user 0.020000 sys 0.020000 (best of 100) Worst-case scenario: a manifest text loaded from a single delta; in the firefox repository manifest node 9a1246ff762e is the chain base for the manifest attached to revision f947d902ed91. Loading this from a full cache file is just as fast as without the cache; the extra node ids ensure a big full cache: $ for node in 9a1246ff762e 1a1922c14a3e 54a31d11a36a 0294517df4aa; do > hgd debugmanifestfulltextcache -a $node > /dev/null > done $ hgd perfmanifest -m 9a1246ff762e ! wall 0.077513 comb 0.080000 user 0.030000 sys 0.050000 (best of 100) $ hgd perfmanifest -m 9a1246ff762e --clear-disk ! wall 0.078547 comb 0.080000 user 0.070000 sys 0.010000 (best of 100)

debug: allow specifying a manifest node rather than a revision

packaging: always execute builddeb from source root Without this, dockerdeb and the make targets that invoke it may fail depending on the pwd at the time of invocation.

perfmoonwalk: make work with filtered repo This also fixes the out-of-range "len(repo)" that weirdly works (and gets the nullid). I suspect it wasn't intentional to include the timing of reading the null revision. Differential Revision: https://phab.mercurial-scm.org/D4017

revlog: don't include trailing nullrev in revlog.revs(stop=len(revlog)) This was an odd side effect of the nullid entry that's in the index. The existing callers (mostly repair.py) seem to have handled it fine. It doesn't seem intentional, and it's pretty surprising, so let's remove that surprise.

patchbomb: ensure all headers and values given to email mod are native strings This lets test-patch-bookmark.t only fail with some harmless header output changes on Python 3, so I think patchbomb might be basically useful on Python 3 now. Differential Revision: https://phab.mercurial-scm.org/D3952

dispatch: making all hg abortions be output with a specific label This allows abortions to be highlighted specially and separately from warnings - for instance, red is a reasonable color for when hg aborts, but is overly dramatic for most warnings produced elsewhere.

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
