Test support for partial-resolution tools
Create a tool that resolves conflicts after line 5 by simply dropping those
lines (even if there are no conflicts there)
$ cat >> "$TESTTMP/head.sh" <<'EOF'
> #!/bin/sh
> for f in "$@"; do
> head -5 $f > tmp
> mv -f tmp $f
> done
> EOF
$ chmod +x "$TESTTMP/head.sh"
...and another tool that keeps only the last 5 lines instead of the first 5.
$ cat >> "$TESTTMP/tail.sh" <<'EOF'
> #!/bin/sh
> for f in "$@"; do
> tail -5 $f > tmp
> mv -f tmp $f
> done
> EOF
$ chmod +x "$TESTTMP/tail.sh"
Set up both tools to run on all patterns (the default), and let the `tail` tool
run after the `head` tool, which means it will have no effect (we'll override it
to test order later)
$ cat >> "$HGRCPATH" <<EOF
> [partial-merge-tools]
> head.executable=$TESTTMP/head.sh
> tail.executable=$TESTTMP/tail.sh
> tail.order=1
> EOF
$ make_commit() {
> echo "$@" | xargs -n1 > file
> hg add file 2> /dev/null
> hg ci -m "$*"
> }
Let a partial-resolution tool resolve some conflicts and leave other conflicts
for the regular merge tool (:merge3 here)

$ make_commit a b2 c d e f2
$ hg up 0

$ make_commit a b3 c d e f3

$ hg merge 1 -t :merge3
merging file
warning: conflicts while merging file! (edit, then use 'hg resolve --mark')
0 files updated, 0 files merged, 0 files removed, 1 files unresolved
use 'hg resolve' to retry unresolved file merges or 'hg merge --abort' to abandon

When a partial-resolution tool resolves all conflicts, the resolution should
be recorded and the regular merge tool should not be invoked for the file.
$ hg up -C 0
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ make_commit a b c d e f2
created new head
$ hg up 0
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ make_commit a b c d e f3

$ hg merge 3 -t false

conflict it had been enabled)

Only tools whose patterns match are run. We make `head` not match here, so
only `tail` should run

If there are several matching tools, they are run in requested order. We move
`head` after `tail` in order here so it has no effect (the conflict in "f" thus
remains).

When using "nomerge" tools (e.g. `:other`), the partial-resolution tools
should not be run.
$ hg up -C 4
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg merge 3 -t :other
0 files updated, 1 files merged, 0 files removed, 0 files unresolved

If a partial-resolution tool resolved some conflict and simplemerge can
merge the rest, then the regular merge tool should not be used. Here we merge
"a b c d e3 f3" with "a b2 c d e f2". The `head` tool resolves the conflict in
"f" and the internal simplemerge merges the remaining changes in "b" and "e".
$ hg up -C 0
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ make_commit a b c d e3 f3
created new head
$ hg merge 1 -t false
merging file
0 files updated, 1 files merged, 0 files removed, 0 files unresolved
