revert: move bulk of revert command from commands to cmdutil
This revision has no functionality change. The code on the original
commands.revert() function has been split. The first part of the
original code, which checks that the command inputs are correct
remains in commands.revert(). The rest of the function, which performs
the actual revert operation has been moved into cmdutil.revert().
The purpose of this change is to make it easier to perform a revert
operation, from other parts of the code. This may be used to implement
reverting of subrepos.
Setup extension:
$ echo "[extensions]" >> $HGRCPATH
$ echo "mq =" >> $HGRCPATH
$ echo "[mq]" >> $HGRCPATH
$ echo "git = keep" >> $HGRCPATH
Test merge with mq changeset as the second parent:
$ hg init m
$ cd m
$ touch a b c
$ hg add a
$ hg commit -m a
$ hg add b
$ hg qnew -d "0 0" b
$ hg update 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg add c
$ hg commit -m c
created new head
$ hg merge
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ hg commit -m merge
abort: cannot commit over an applied mq patch

Issue529: mq aborts when merging patch deleting files
$ checkundo()
> {
> if [ -f .hg/store/undo ]; then
> echo ".hg/store/undo still exists"
> fi
> }
Commit two dummy files in "init" changeset:
$ hg init t
$ cd t
$ echo a > a
$ echo b > b
$ hg ci -Am init
adding a
adding b
$ hg tag -l init
Create a patch removing a:
$ hg qnew rm_a
$ hg rm a
$ hg qrefresh -m "rm a"
Save the patch queue so we can merge it later:
$ hg qsave -c -e
copy $TESTTMP/t/.hg/patches to $TESTTMP/t/.hg/patches.1 (glob)
$ checkundo
Update b and commit in an "update" changeset:
$ hg up -C init
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo b >> b
$ hg st
M b
$ hg ci -m update
created new head
# Here, qpush used to abort with :
# The system cannot find the file specified => a
$ hg manifest
a
b
$ hg qpush -a -m
merging with queue at: $TESTTMP/t/.hg/patches.1 (glob)
applying rm_a
now at: rm_a
$ checkundo
$ hg manifest
b
Ensure status is correct after merge:
$ hg qpop -a
popping rm_a
popping .hg.patches.merge.marker
patch queue now empty
$ cd ..
Classic MQ merge sequence *with an explicit named queue*:
$ hg init t2
$ cd t2
$ echo '[diff]' > .hg/hgrc
$ echo 'nodates = 1' >> .hg/hgrc
$ echo a > a
$ hg ci -Am init
adding a
$ echo b > a
$ hg ci -m changea
$ hg up -C 0
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg cp a aa
$ echo c >> a
$ hg qnew --git -f -e patcha
$ echo d >> a
$ hg qnew -d '0 0' -f -e patcha2
Create the reference queue:
$ hg qsave -c -e -n refqueue
copy $TESTTMP/t2/.hg/patches to $TESTTMP/t2/.hg/refqueue (glob)
$ hg up -C 1
1 files updated, 0 files merged, 1 files removed, 0 files unresolved
Merge:
$ HGMERGE=internal:other hg qpush -a -m -n refqueue
merging with queue at: $TESTTMP/t2/.hg/refqueue (glob)
