Create integration instructions about git-diffall HOT 6 CLOSED

I just tried this script and it works directly with BC3:

1. $ git config --global diff.tool bc3 (supposes BC3 is in the PATH).
2. Copy git-diffall somewhere on the PATH
3. Run $ git-diffall in the repository.

from git-diffall.

@wernight How do you have BeyondCompare set up in the gitconfig (the command string)? Because when I run the current git-diffall with my BC configuration (which works totally fine for single files), I get the following error:

rm: cannot remove directory '/tmp/git-diffall-tmp': Permission denied

And the folder is deleted just when BC shows up, which makes every detail diff view inside BC not working.

from git-diffall.

I believe my /tmp is working fine but I remember some time ago having issues with it. Can you write in /tmp? I'm also using the Git defaut bc3 which calls BComp.com in modern msysgit and will wait until it exists.

It can write the directory, yes. It actually does its whole job, all files are copied correctly and the diff launches up correctly. It’s just that it deletes everything just when BC3 is started. And I guess it cannot delete the /tmp directory itself (but the contents) because BC3 blocks its access.

So all that’s not working is that the script does not wait until BC3 is closed but directly deletes the files again. It however does work with the normal git difftool.

The script requires that the external diff tool does not fork from the process where the script is running. The script is supposed to work this way:

1. Call git diffall
2. Script copies the files it needs to /tmp
3. Script opens your external diff tool
4. Script waits until your external diff tool exits
5. Script deletes the files in /tmp

If BeyondCompare is forking the process, then the script will assume it is done and immediately proceed to step 5.

I don't have BC installed right now, but their help docs show the following command-line executable choices:

So this tells us that your setup must use BComp.com (should be the default as noted by @poke above).
