obsolete: sort obsmarkers during exchange...
obsolete: sort obsmarkers during exchange Because bundle2 allows a more precise exchange of obsmarkers during pull, it sends them in a different order (previously unstable because of sets.) As a result, they are added to the repository in a different order. To stabilize the order and ensure tests are unchanged when moving from bundle1 to bundle2 we sort markers when exchanging them. In the long run, the obsstore will probably not use a linear storage.

treemanifest: store submanifest revlog per directory...
 r25091
Set up repo
$ hg --config experimental.treemanifest=True init repo
$ cd repo
Requirements get set on init
$ grep treemanifest .hg/requires
treemanifest
Without directories, looks like any other repo
$ echo 0 > a
$ echo 0 > b
$ hg ci -Aqm initial
$ hg debugdata -m 0
a\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)
b\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)
Submanifest is stored in separate revlog
$ mkdir dir1
$ echo 1 > dir1/a
$ echo 1 > dir1/b
$ echo 1 > e
$ hg ci -Aqm 'add dir1'
$ hg debugdata -m 1
a\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)
b\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)

$ hg debugdata .hg/store/meta/dir1/00manifest.i 0
a\x00b8e02f6433738021a065f94175c7cd23db5f05be (esc)

Can add nested directories
$ mkdir dir1/dir1
$ echo 2 > dir1/dir1/a
$ echo 2 > dir1/dir1/b
$ mkdir dir1/dir2
$ echo 2 > dir1/dir2/a
$ echo 2 > dir1/dir2/b
$ hg ci -Aqm 'add dir1/dir1'
$ hg files -r .
a
b
dir1/a
dir1/b
dir1/dir1/a
dir1/dir1/b
dir1/dir2/a
dir1/dir2/b
e
Revision is not created for unchanged directory
$ mkdir dir2
$ echo 3 > dir2/a
$ hg add dir2
adding dir2/a
$ hg debugindex .hg/store/meta/dir1/00manifest.i > before
$ hg ci -qm 'add dir2'
$ hg debugindex .hg/store/meta/dir1/00manifest.i > after
$ diff before after
$ rm before after
Removing directory does not create an revlog entry
$ hg rm dir1/dir1
removing dir1/dir1/a
removing dir1/dir1/b
$ hg debugindex .hg/store/meta/dir1/dir1/00manifest.i > before
$ hg ci -qm 'remove dir1/dir1'
$ hg debugindex .hg/store/meta/dir1/dir1/00manifest.i > after
$ diff before after
$ rm before after
Check that hg files (calls treemanifest.walk()) works
$ hg co 'desc("add dir2")'
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg files -r . dir1
dir1/a
dir1/b
dir1/dir1/a
dir1/dir1/b
dir1/dir2/a
dir1/dir2/b
Check that status between revisions works (calls treemanifest.matches())
$ hg status --rev 'desc("add dir1")' --rev . dir1
A dir1/dir1/a
A dir1/dir1/b
A dir1/dir2/a
A dir1/dir2/b
Merge creates 2-parent revision of directory revlog
$ echo 5 > dir1/a
$ hg ci -Aqm 'modify dir1/a'
$ hg co '.^'
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo 6 > dir1/b
$ hg ci -Aqm 'modify dir1/b'
$ hg merge 'desc("modify dir1/a")'
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ hg ci -m 'conflict-free merge involving dir1/'
$ cat dir1/a

Merge keeping directory from parent 1 does not create revlog entry. (Note that
dir1's manifest does change, but only because dir1/a's filelog changes.)

$ echo 8 > dir2/a
