Tuesday was spent dealing with lock files. Turned out there were some bugs
|
|
|
|
|
in the `annex.pidlock` configuration that prevented it from working, and
|
|
|
|
|
could even lead to data loss.
|
|
|
|
|
|
|
|
|
|
And then more lock files today, since I needed to lock git's index file the
|
|
|
|
|
same way git does. This involved finding out how to emulate `O_EXCL` under
|
|
|
|
|
Windows. Urgh.

Finally got back to working on [[design/adjusted_branches]] today. And, I've just
|
2016-03-03 21:19:11 +00:00
|
|
|
gotten syncing of commits from adjusted branches back to the orginal branch
|
|
|
|
|
working! Time for short demo of what I've been building for the past couple
|
|
|
|
|
weeks:

The commit was made on top of the commit that generated the adjusted branch.
|
|
|
|

It's not yet reached the master branch.

Now the commit has reached master. Notice how the history of the adjusted
|
|
|
|
|
branch was rebased on top of the updated master branch as well.

Just as we'd want, the file is locked in master, and unlocked in
|
|
|
|
|
the adjusted branch.
|
|
|
|
|
|
|
|
|
|
(Not shown: git annex sync will also merge in and adjust changes from remotes.)
|
|
|
|
|
|
|
|
|
|
So, that all looks great! But, it's cheating a bit, because it locks
|
|
|
|
|
all files when updating the master branch. I need to make it remember,
|
|
|
|
|
somehow, when files were originally unlocked, and keep them unlocked. Also
|
|
|
|
|
want to implement other adjustments, like hiding files whose content is not
|
|
|
|
|
present.
