dirstate-v2: freeze the on-disk format

It seems the format as reached a good balance. With a core of new capabilities
that motivated it initially and enough new feature and room for future
improvement to be a clear progress we can set a milestone for.

Having the format frozen will help the feature to get real life testing, outside
of the test suite.

The feature itself stay experimental but the config gains a new name to avoid
people enable non-frozen version by default.

If too many bugs are reported during the RC we might move the format back to
experimental and drop its support in future version (in favor of a new one)

 # "out of experimental" todo list.
 #
 # * include management of a persistent nodemap in the main docket
 # * enforce a "no-truncate" policy for mmap safety
 #      - for censoring operation
 #      - for stripping operation
 #      - for rollback operation
 # * proper streaming (race free) of the docket file
 # * track garbage data to evemtually allow rewriting -existing- sidedata.
 # * Exchange-wise, we will also need to do something more efficient than
 #   keeping references to the affected revlogs, especially memory-wise when
 #   rewriting sidedata.
 # * introduce a proper solution to reduce the number of filelog related files.
 # * use caching for reading sidedata (similar to what we do for data).
 # * no longer set offset=0 if sidedata_size=0 (simplify cutoff computation).
 # * Improvement to consider
 #   - avoid compression header in chunk using the default compression?
 #   - forbid "inline" compression mode entirely?
 #   - split the data offset and flag field (the 2 bytes save are mostly trouble)
 #   - keep track of uncompressed -chunk- size (to preallocate memory better)
 #   - keep track of chain base or size (probably not that useful anymore)

     repository.
 
     The factory functions each receive various state that may be consulted
     as part of deriving a type.
 
     Extensions should wrap these factory functions to customize repository type
     creation. Note that an extension's wrapped function may be called even if
     that extension is not loaded for the repo being constructed. Extensions

 Test that accessing to invalid changelog cache is avoided at
 subsequent operations even if repo object is reused even after failure
 of transaction (see 0a7610758c42 also)
 
 "hg log" after failure of transaction is needed to detect invalid
 cache in repoview: this can't detect by "hg verify" only.
 
 Combination of "finalization" and "empty-ness of changelog" (2 x 2 =
 4) are tested, because '00changelog.i' are differently changed in each
 cases.

 "hg status" below should excludes "e", of which exec flag is set, for
 portability of test scenario, because unsure but missing "e" is
 treated differently in _checklookup() according to runtime platform.

 Configure a merge tool that runs status in the middle of the rebase. The goal of
 the status call is to trigger a potential bug if fsmonitor's state is written
 even though the wlock is held by another process. The output of 'hg status' in
 the merge tool goes to /dev/null because we're more interested in the results of
 'hg status' run after the rebase.

 Merge largefiles into lfs branch
 
 The largefiles extension will prompt to use the normal or largefile when merged
 into the lfs files.  `hg manifest` will show standins if present.  They aren't,
 because largefiles merge doesn't merge content.  If it did, selecting (n)ormal
 would convert to lfs on commit, if appropriate.
 
 BUG: Largefiles isn't running the merge tool, like when two lfs files are
 merged.  This is probably by design, but it should probably at least prompt if
 content should be taken from (l)ocal or (o)ther as well.

 When both largefiles and lfs are configured to add by size, the tie goes to
 largefiles since it hooks cmdutil.add() and lfs hooks the filelog write in the
 commit.  By the time the commit occurs, the tracked file is smaller than the
 threshold (assuming it is > 41, so the standins don't become lfs objects).

   lfs.txt
   normal.txt
 
   $ hg rm large_by_size.bin
   $ hg ci -m 'remove large_by_size.bin'
 
 Largefiles doesn't do anything special with diff, so it falls back to diffing
 the standins.  Extdiff also is standin based comparison.  Diff and extdiff both
 work on the original file for lfs objects.

 A largefiles repo can be converted to lfs.  The lfconvert command uses the
 convert extension under the hood with --to-normal.  So the --config based
 parameters are available, but not --authormap, --branchmap, etc.

 No diffs when comparing merge and p1 that kept p1's changes.  Diff of lfs to
 largefiles no longer operates in standin files.
 
 This `head -n 20` looks dumb (since we expect no output), but if something
 breaks you can get 1048576 lines of +y in the output, which takes a looooooong
 time to print.

 We only make the following assertions for the flat test case since in the
 treemanifest test case debugsparse fails with "path ends in directory
 separator: outside/" which seems like a bug unrelated to the regression this is
 testing for.

 Regression test for a previous bug in Rust/C FFI for the `Revlog_CAPI` capsule:
 in places where `mercurial/cext/revlog.c` function signatures use `Py_ssize_t`
 (64 bits on Linux x86_64), corresponding declarations in `rust/hg-cpython/src/cindex.rs`
 incorrectly used `libc::c_int` (32 bits).
 As a result, -1 passed from Rust for the null revision became 4294967295 in C.

 If the nodemap is not gated behind a requirements, an unaware client can alter
 the repository so the revlog used to generate the nodemap is not longer
 compatible with the persistent nodemap. We need to detect that.
 
   $ hg up "$NODE~5"
   0 files updated, 0 files merged, 4 files removed, 0 files unresolved
   $ echo bar > babar
   $ hg add babar
   $ hg ci -m 'babar'
   created new head
   $ OTHERNODE=`hg log -r tip -T '{node}\n'`
   $ hg log -r "$OTHERNODE" -T '{rev}\n'
   5004
 
   $ hg --config extensions.strip= strip --rev "$NODE~1" --no-backup
 
 the nodemap should detect the changelog have been tampered with and recover.

 Check race condition when multiple process write new data to the repository
 ---------------------------------------------------------------------------
 
 In this test, we check that two writers touching the repositories will not
 overwrite each other data. This test is prompted by the existent of issue6554.
 Where a writer ended up using and outdated docket to update the repository. See
 the dedicated extension for details on the race windows and read/write schedule
 necessary to end up in this situation: testlib/persistent-nodemap-race-ext.py
 
 The issue was initially observed on a server with a high push trafic, but it
 can be reproduced using a share and two commiting process which seems simpler.
 
 The test is Rust only as the other implementation does not use the same
 read/write patterns.

 Check that remote secret changeset are ignore when checking creation of remote heads
 
 We add a secret head into the push destination. This secret head shadows a
 visible shared between the initial repo and the push destination.

   $ hg phase .

 We now try to push a new public changeset that descend from the common public
 head shadowed by the remote secret head.

 Make sure .hg doesn't show up even as a symlink
 
   $ hg init repo0
   $ mkdir symlink-repo0
   $ cd symlink-repo0
   $ ln -s ../repo0/.hg
   $ hg status
 
 If the size hasn’t changed but mtime has, status needs to read the contents
 of the file to check whether it has changed
 
   $ echo 1 > a
   $ echo 1 > b
   $ touch -t 200102030000 a b
   $ hg commit -Aqm '#0'
   $ echo 2 > a
   $ touch -t 200102040000 a b

 Asking specifically for the status of a deleted/removed file

   $ hg rm a
   $ hg rm b
   $ hg status a
   R a
   $ hg commit -qm '#1'
   $ hg status a

 Check using include flag with pattern when status does not need to traverse
 the working directory (issue6483)
 
   $ cd ..
   $ hg init issue6483
   $ cd issue6483
   $ touch a.py b.rs
   $ hg add a.py b.rs
   $ hg st -aI "*.py"
   A a.py
 
 Also check exclude pattern
 
   $ hg st -aX "*.rs"
   A a.py
 
 issue6335
 When a directory containing a tracked file gets symlinked, as of 5.8
 `hg st` only gives the correct answer about clean (or deleted) files
 if also listing unknowns.
 The tree-based dirstate and status algorithm fix this:
 
 #if symlink no-dirstate-v1 rust
 
   $ cd ..
   $ hg init issue6335
   $ cd issue6335
   $ mkdir foo
   $ touch foo/a
   $ hg ci -Ama
   adding foo/a
   $ mv foo bar
   $ ln -s bar foo
   $ hg status
   ! foo/a
   ? bar/a
   ? foo
 
   $ hg status -c  # incorrect output without the Rust implementation
   $ hg status -cu
   ? bar/a
   ? foo
   $ hg status -d  # incorrect output without the Rust implementation
   ! foo/a
   $ hg status -du
   ! foo/a
   ? bar/a
   ? foo
 
 #endif
 
 
 Create a repo with files in each possible status
 
   $ cd ..
   $ hg init repo7
   $ cd repo7
   $ mkdir subdir
   $ touch clean modified deleted removed
   $ touch subdir/clean subdir/modified subdir/deleted subdir/removed
   $ echo ignored > .hgignore
   $ hg ci -Aqm '#0'
   $ echo 1 > modified
   $ echo 1 > subdir/modified
   $ rm deleted
   $ rm subdir/deleted
   $ hg rm removed
   $ hg rm subdir/removed
   $ touch unknown ignored
   $ touch subdir/unknown subdir/ignored
 
 Check the output
 
   $ hg status
   M modified
   M subdir/modified
   R removed
   R subdir/removed
   ! deleted
   ! subdir/deleted
   ? subdir/unknown
   ? unknown
 
   $ hg status -mard
   M modified
   M subdir/modified
   R removed
   R subdir/removed
   ! deleted
   ! subdir/deleted
 
   $ hg status -A
   M modified
   M subdir/modified
   R removed
   R subdir/removed
   ! deleted
   ! subdir/deleted
   ? subdir/unknown
   ? unknown
   I ignored
   I subdir/ignored
   C .hgignore
   C clean
   C subdir/clean
 
 Note: `hg status some-name` creates a patternmatcher which is not supported
 yet by the Rust implementation of status, but includematcher is supported.
 --include is used below for that reason
 
 #if unix-permissions
 
 Not having permission to read a directory that contains tracked files makes
 status emit a warning then behave as if the directory was empty or removed
 entirely:
 
   $ chmod 0 subdir
   $ hg status --include subdir
   subdir: Permission denied
   R subdir/removed
   ! subdir/clean
   ! subdir/deleted
   ! subdir/modified
   $ chmod 755 subdir
 
 #endif
 
 Remove a directory that contains tracked files
 
   $ rm -r subdir
   $ hg status --include subdir
   R subdir/removed
   ! subdir/clean
   ! subdir/deleted
   ! subdir/modified
 
 … and replace it by a file
 
   $ touch subdir
   $ hg status --include subdir
   R subdir/removed
   ! subdir/clean
   ! subdir/deleted
   ! subdir/modified
   ? subdir
 
 Replaced a deleted or removed file with a directory
 
   $ mkdir deleted removed
   $ touch deleted/1 removed/1
   $ hg status --include deleted --include removed
   R removed
   ! deleted
   ? deleted/1
   ? removed/1
   $ hg add removed/1
   $ hg status --include deleted --include removed
   A removed/1
   R removed
   ! deleted
   ? deleted/1
 
 Deeply nested files in an ignored directory are still listed on request
 
   $ echo ignored-dir >> .hgignore
   $ mkdir ignored-dir
   $ mkdir ignored-dir/subdir
   $ touch ignored-dir/subdir/1
   $ hg status --ignored
   I ignored
   I ignored-dir/subdir/1
 
 Check using include flag while listing ignored composes correctly (issue6514)
 
   $ cd ..
   $ hg init issue6514
   $ cd issue6514
   $ mkdir ignored-folder
   $ touch A.hs B.hs C.hs ignored-folder/other.txt ignored-folder/ctest.hs
   $ cat >.hgignore <<EOF
   > A.hs
   > B.hs
   > ignored-folder/
   > EOF
   $ hg st -i -I 're:.*\.hs$'
   I A.hs
   I B.hs
   I ignored-folder/ctest.hs
 
 #if rust dirstate-v2
 
 Check read_dir caching
 
   $ cd ..
   $ hg init repo8
   $ cd repo8
   $ mkdir subdir
   $ touch subdir/a subdir/b
   $ hg ci -Aqm '#0'
 
 The cached mtime is initially unset
 
   $ hg debugdirstate --all --no-dates | grep '^ '
       0         -1 unset               subdir
 
 It is still not set when there are unknown files
 
   $ touch subdir/unknown
   $ hg status
   ? subdir/unknown
   $ hg debugdirstate --all --no-dates | grep '^ '
       0         -1 unset               subdir
 
 Now the directory is eligible for caching, so its mtime is save in the dirstate
 
   $ rm subdir/unknown
   $ hg status
   $ hg debugdirstate --all --no-dates | grep '^ '
       0         -1 set                 subdir
 
 This time the command should be ever so slightly faster since it does not need `read_dir("subdir")`
 
   $ hg status
 
 Creating a new file changes the directory’s mtime, invalidating the cache
 
   $ touch subdir/unknown
   $ hg status
   ? subdir/unknown
 
   $ rm subdir/unknown
   $ hg status
 
 Removing a node from the dirstate resets the cache for its parent directory
 
   $ hg forget subdir/a
   $ hg debugdirstate --all --no-dates | grep '^ '
       0         -1 set                 subdir
   $ hg ci -qm '#1'
   $ hg debugdirstate --all --no-dates | grep '^ '
       0         -1 unset               subdir
   $ hg status

   re-delta-parent
      deltas within internal storage will be recalculated to choose an optimal base revision where this was not already done; the size of the repository may shrink and various operations may become faster; the first time this optimization is performed could slow down upgrade execution considerably; subsequent invocations should not run noticeably slower
   
   re-delta-multibase
      deltas within internal storage will be recalculated against multiple base revision and the smallest difference will be used; the size of the repository may shrink significantly when there are many merges; this optimization will slow down execution in proportion to the number of merges in the repository and the amount of files in the repository; this slow down should not be significant unless there are tens of thousands of files and thousands of merges
   
   re-delta-all
      deltas within internal storage will always be recalculated without reusing prior deltas; this will likely make execution run several times slower; this optimization is typically not needed
   
   re-delta-fulladd
      every revision will be re-added as if it was new content. It will go through the full storage mechanism giving extensions a chance to process it (eg. lfs). This is similar to "re-delta-all" but even slower since more logic is involved.

   repository lacks features recommended by current config options:

   dotencode
      storage of filenames beginning with a period or space may not work correctly
   
   generaldelta
      deltas within internal storage are unable to choose optimal revisions; repository is larger and slower than it could be; interaction with other repositories may require extra network and CPU resources, making "hg push" and "hg pull" slower
   
   sparserevlog
      in order to limit disk reading and memory usage on older version, the span of a delta chain from its root to its end is limited, whatever the relevant data in this span. This can severly limit Mercurial ability to build good chain of delta resulting is much more storage space being taken and limit reusability of on disk delta during exchange.
