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 "$*"

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.

|

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".
