Bug ID: 5224
Summary: hg import from a repo subdirectory should imply
`--prefix .`
Product: Mercurial
Version: 3.8-rc
Hardware: Macintosh
OS: Mac OS
Status: UNCONFIRMED
Severity: feature
Priority: wish
Component: Mercurial
Assignee: bugzilla at selenic.com
Reporter: beng at fb.com
CC: mercurial-devel at selenic.com
I'm trying to cross-port a patch between two mostly-similar repositories which
have a directory structure like:
foo/bar/my-lib
baz/bar/my-lib
I used `hg export` to export the commit from the first repository, then ran:
% cd /path/to/baz/bar
% hg import -p 2 /path/to/patch
The import failed with the error:
unable to find 'my-lib/file1' for patching
even though 'my-lib/file1' existed from my current directory.
Eventually, I figured out the problem was that `hg import` implicitly runs from
the root of the repository. With trial and error and help from a few experts,
we found that the correct command was:
% cd /path/to/baz/bar
% hg import -p 2 --prefix . /path/to/patch
For the Principle of Least Astonishment, I think it'd be really nice if `hg
import` when run from a subdirectory of the repo root implied `--prefix .`.
Then it'd behave more like `patch`.
