Empty directories when update to <branch>

[Martin McGovern-3]

Hi,

I'm evaluating mercurial for the company I work for. So far I've migrated the CVS repo to mercurial and am now evaluating tool support.

In eclipse when I use "update to" and select a branch I see empty directories everywhere. They correspond to directories on other branches or the old CVS HEAD. It's very misleading for someone used to CVS.

Is there any way to tell mercurial eclipse to ignore these, or not display them? Can mercurial actually tell that they should not exist for a branch?

Thanks,
Martin

Mercurial is not tracking the directories themselves, it is only
tracking the files within. When you update to different branches or
revisions, the files are added/deleted as necessary. If a directory tree
becomes empty, it is deleted.

But you might have some ignored files lying around in the directories,
which prevents from being deleted. I delete them with

  rm $(hg status -in)

You can also use the purge extension:

This is for plain Mercurial on the command line -- I don't know anything
about Eclipse.

Thanks Martin,

I wasn't sure what mercurial is supposed to do so I couldn't tell if it was the eclipse extension causing the problem. It looks like the update failed to delete the directories when it removed the files.

I'll stick to the command line until I'm sure I know what should be happening.

Hi,

if your operating system is Windows, you could be experiencing issue 1861 (http://mercurial.selenic.com/bts/issue186). It's solved in crew-stable and hg-stable repositories.

Regards,
Pascal.

Just to be sure, the correct link: http://mercurial.selenic.com/bts/issue1861

Thanks, I'll see if that makes a difference.

Serves me right for using windows ;-)

Careful: if your CVS repo has tags or branches, 'hg convert' doesn't
always convert them accurately.  See
http://vc.gerg.ca/hg/cvs2svn/raw-file/6de4ed4e3b68/README.cvs2hg for
an explanation.  AFAIK, my fork of cvs2svn (clone
http://vc.gerg.ca/hg/cvs2svn/) is the only CVS-to-hg conversion tool
that gets tags and branches right.

If you have no tags and no branches, though, 'hg convert' should be fine.

Thanks Greg,

Hg convert crashed due to a unknown error with a CVS command when I tried it. I migrated via Subversion with cvs2svn (which I'm also evaluating) instead. I hope this is adequate

Yes, that will probably work.  If you're interested, I have
implemented direct CVS->Mercurial conversion using the cvs2svn
infrastructure.  With breathtaking originality, I called the result
cvs2hg.  Just clone http://vc.gerg.ca/hg/cvs2svn/ and see
README.cvs2hg.  If cvs2svn works for you, cvs2hg should work better.

(Yes, this is going to be pushed upstream to cvs2svn eventually, and
no it has not happened yet.)
