Mercurial's hg bcomp exits before BC is done

[Andomar]

Hi, I'm using Mercurial. When I run "hg bcomp ." on a directory with multiple changes, hg puts both branches in a temp directory and asks Beyond Compare to compare them. This works fine and BC even displays the filenames.

However, "hg bcomp" exits right after starting Beyond Compare. When it exits it cleans up the directory, so there's nothing left to see.

Is there any way around this?

Hello,

Which version and OS of Mercurial are you currently using? Is it one of the later versions (like TortoiseHG 2.0.2+ on Windows) that has "beyondcompare3" in the dropdown, or did you set it up manually following the instructions here:

Hi Aaron,

Thanks for your reply. I'm running Windows Server 2003. Mercurial's "hg --version" returns:

    Mercurial Distributed SCM (version 1.9+10-e9264b45237d)

I followed the instructions in the post you linked. It works fine for single files, but a change that spans multiple files fails in the way I described.

Kind Regards,
Andomar

One solution is to point Mercurial at a .cmd file instead, like:

"C:\Program Files (x86)\Beyond Compare 3\BComp.exe" %*
pause

This works, but you have to click away the pause at the end.

Hello Andomar,

Thanks for the feedback and workaround. The KB article goes into detail on how to setup BC3 as the Text Diff or Text Merge tools, but we don't have a good article or method as a directory/revision diff tool. We'll have to look into this, but the pause method does seem to work with Mercurial HG (or TortoiseHG).

I ran into the same problem with the temp files getting deleted too soon, but changing the cmd.bcomp from BComp.exe to BCompare.exe in my .hgrc file fixed the problem. I got this solution from the post:

From the rest of that thread it seems this is not be the way Scooter feels we should go. But it has the advantage of actually working as opposed to not...
