subrepo: add basic support to hgsubrepo for the files command
Paths into the subrepo are not yet supported.
The need to use the workingctx in the subrepo will likely be used more in the
future, with the proposed working directory revset symbol. It is also needed
with archive, if that code is to be reused to support 'extdiff -S'.
Unfortunately, it doesn't seem possible to put the smarts in subrepo.subrepo(),
as it breaks various status and diff tests.
I opted not to pass the desired revision into the subrepo method explicitly,
because the only ones that do pass an explicit revision are methods like status
and diff, which actually operate on two contexts- the subrepo state and the
explicitly passed revision.
Create a repository:
$ hg config
defaults.backout=-d "0 0"
defaults.commit=-d "0 0"
defaults.shelve=--date "0 0"
defaults.tag=-d "0 0"
largefiles.usercache=$TESTTMP/.cache/largefiles (glob)
ui.slash=True
ui.interactive=False
ui.mergemarkers=detailed
ui.promptecho=True
$ hg init t
$ cd t
Make a changeset:
$ echo a > a
$ hg add a
$ hg commit -m test
This command is ancient:
$ hg history
changeset: 0:acb14030fe0a
tag: tip
user: test
date: Thu Jan 01 00:00:00 1970 +0000
summary: test
Verify that updating to revision 0 via commands.update() works properly
$ cat <<EOF > update_to_rev0.py
> from mercurial import ui, hg, commands
> myui = ui.ui()
> repo = hg.repository(myui, path='.')
> commands.update(myui, repo, rev=0)
> EOF
$ hg up null
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ python ./update_to_rev0.py
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg identify -n
0
Poke around at hashes:
$ hg manifest --debug
b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 644 a
$ hg cat a
a
Verify should succeed:
$ hg verify
checking changesets
checking manifests
crosschecking files in changesets and manifests
checking files
1 files, 1 changesets, 1 total revisions
At the end...
$ cd ..
