Bad merging with stgit or git

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have a -git tree that generated a really bad result when committed by
Linus, generating a really bad history log. My tree is located at:
kernel.org:/pub/scm/linux/kernel/git/mchehab/v4l-dvb.git.

I'll try to make a brief from what's happened:

According to him:
"
...
In particular, commit e338b736f1aee59b757130ffdc778538b7db18d6 is crap,
crap, CRAP.
It's "Merging Linus tree", but it's not a merge at all: you have just 
applied the _patch_ to merge the changes in my tree, but you haven't 
actually told git to do so.

I don't know how/why you did that, but it's totally bogus, and I refuse
to 
pull from that tree. That's a 5000+ line diff, affecting about 180
files! 
...
"

After a further analysis, it seemed that a merge conflict were badly
solved. It is showing this message to Linus:

For me, those tree last lines, don't appear. Instead, it just shows,
with git-show:

and a diff file, with:

With git-cat-file, it shows:

Merging Linus tree

It shouldn't have any conflicts here for Linus, since those patches came
from his tree.

My current procedure is:

branch origin - Linus tree replica
branch work - my stgit main tree
branch work-fixes - my stgit tree for bug fixes
branch master - patches to current kernel
branch devel - patches to next kernel

All patches are generated against work branch, with stgit.
Branch work-fixes receives patches by using:

        stg pick <sha>@work

Before commiting to kernel.org, I do:
at origin:
        git pull linus_tree

at master:
        git pull . origin
        git pull . work-fixes

at devel:
        git pull . origin
        git pull . work

My environment is:

Stacked GIT 0.8.1
git version 1.2.4.gfd662
Python version 2.4.2 (#2, Jan 30 2006, 18:33:58)
[GCC 4.0.2 (4.0.2-1mdk for Mandriva Linux release 2006.1)]

Any ideas?
