A trailing slash can be hard to see.
This morning I tried to commit to a Mercurial repository which contained sub-repositories. One of those subrepos had been added a few days earlier, along with the corresponding
.hgsub had been committed explicitly, without incident.
$ vi .hgsub # add entry for src/baz/foo $ hg ci -m "Some comment." .hgsub $
Today, for the first time since adding the subrepo, I tried an hg commit at the top-level of my repository. Mercurial responded with an error message:
$ hg ci -m "Blah." abort: path 'src/baz/foo/' is inside repo 'src/baz/foo'
It took a few minutes of quiet contemplation before I finally saw the problem:
abort: path 'src/baz/foo/' is inside repo 'src/baz/foo'
Once the extraneous slash was removed from
.hgsub, everything was fine.
