问题
I'm offline a lot.
So normally, I use one local clone as a "hub" for features, bugs, etc.
hg clone local-hub bug-123
Works offline. Cool.
Can I use a similar workflow if that project contains remote subrepositories?
Because, if .hgsub says
sub/shared = http://server/hg/shared
hg clone says
abort: error: getaddrinfo failed
Note that once the clone is created (while connected), push and pull will use the path in the subrepo's hgrc (instead of the location in .hgsub). So I can point this to a local clone and everything is cool.
But clone looks at .hgsub (as it's supposed to). So if the "blessed" subrepo is on a server, I can't create new clones offline, even though the files I need are right there.
This is a problem, right?
回答1:
Ideally whomever set up the project uses relative URLs in their .hgsub file like this:
sub/shared = ../shared
and then, of course, actually makes shared a sibling of the main repo. Then as long as you have cloned down the main repo and the subs (as siblings) then everything will work out.
If they've used absolute URLs in their .hgsub file you can work around it using the subpaths section in your .hgrc like this:
[subpaths]
http://server/hg/shared = ../shared
which provides a translation layer in your client.
回答2:
The canonical way to use subrepositories is to have X = X paths in the .hgsub file:
sub/shared = sub/shared
That way a clone will structurally look just like the original -- and so you can use the clone to make further (local!) clones.
However, this is not always possible, for example, Bitbucket wont let you create the nested repositories on their server. In that case, the ../X style paths in the .hgsub file is better, and you can use the subpaths configuration section to translate these paths into paths you can use locally.
