debugbuilddag: build a changelog dag from a concise description
Useful in tests to quickly build a complex DAG in an empty repo.
Handles local tags and named branches.
Options to, at each rev,
- create a new file,
- overwrite the same file,
- append to the same file,
- write to a specific line in a mergeable file.
Can run shell commands during DAG buildup.
#!/bin/sh
hg init repo
cd repo
touch foo
hg ci -Am 'add foo'
hg up -C null
# this should be stored as a delta against rev 0
echo foo bar baz > foo
hg ci -Am 'add foo again'
hg debugindex .hg/store/data/foo.i
