Hi Simon,
[8] Cansel the patman and check the git-log and you will find Patman tags are gone!!
By cancel I guess you mean to press 'q' when it asks to send the first email?
Yes.
If you give the -a flag it will avoid trying to apply the patches, and the problem does not happen.
The problem is that when patman applies the patches it checks out a new branch, uses 'git am' to apply the patches one by one, and then tries to go back to the old branch. Since the branch is called 'undefined' these doesn't really work. It seems that 'undefined' is created by git and is persistent after it is created. It's a bit odd but I may be missing something.
Anyway I think I can put in a check for the 'undefined' branch and avoid this.
Sorry, I don't have this level of understanding of how Patman works, but... anyway -a option worked for me and I'm happy.
Thanks!
Best Regards Masahiro Yamada
