commit: abort on merge with missing files
Here is a script illustrating the previous behaviour:
The merge brings a new file 'b' from remote
$ hg merge 1 --debug
searching for copies back to rev 1
unmatched files in other:
b
resolving manifests
overwrite: False, partial: False
ancestor: 07f494440405, local: 540395c44225+, remote: 102a90ea7b4a
b: remote created -> g
updating: b 1/1 files (100.00%)
getting b
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
Delete but do not remove b
$ rm b
$ hg st
! b
The commit succeeds
$ hg commit -m merge
$ hg parents --template "{rev} {desc|firstline} files: {files}\n"
3 merge files:
$ hg st
! b
b changes were ignored, but even b existence was ignored
$ hg manifest
a
This happens because localrepo.commitctx() checks the input ctx.files(), which
is empty for workingctx.files() only returns added, modified or removed
entries, and bypass files/manifest updates completely. So the committed
revision manifest is the same as its first parent one, not containing the 'b'
file.
This patch forces the commit to abort in presence of a merge and missing files.
test-merge4.t is modified accordingly as it was introduced to check hg was not
just terminating with a traceback (5e9e8b8d2629).

SVN wants all paths to start with a slash. Unfortunately, Windows ones
don't. Handle that.

Modify one of the externals to point to a different path so we can
test having obstructions when switching branches on checkout:
$ hg checkout tip
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo "obstruct = [svn] $SVNREPO/externals" >> .hgsub
$ svn co -r5 --quiet "$SVNREPO"/externals obstruct
$ hg commit -m 'Start making obstructed working copy'
$ hg book other
$ hg co -r 'p1(tip)'
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo "obstruct = [svn] $SVNREPO/src" >> .hgsub
$ svn co -r5 --quiet "$SVNREPO"/src obstruct
$ hg commit -m 'Other branch which will be obstructed'
created new head
Switching back to the head where we have another path mapped to the
same subrepo should work if the subrepo is clean.
$ hg co other
A *obstruct/other (glob)
Checked out revision 1.
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
This is surprising, but is also correct based on the current code:
$ echo "updating should (maybe) fail" > obstruct/other
$ hg co tip
abort: crosses branches (merge branches or use --clean to discard changes)
