How to do a git rebase master

[jcohenadad]

Working on a branch, I wanted to update it with a recently-updated master branch.

I went ahead with the traditional git rebase master, but encountered the following issue:

What's strange, is that the branch jca/17-defacing started of from master, the problematic files listed above where updated only in jca/17-defacing (not on master), so I am wondering why this conflict is showing up. Is this a singularity of git-annex? @kousu @drulex any idea?

Since this was urgent, I went ahead and clicked on "rebase and merge" directly on github (without being able to rebase and wait for travis)

[jcohenadad]

Even more problematic:

• i renamed the local repos

• did a fresh git clone, git annex init and git annex get, but ran into this:

  [jcohen@gra-login3 data-multi-subject]$ git-annex get sub-cmrra02/anat/sub-cmrra02_T2w.nii.gz 
  get sub-cmrra02/anat/sub-cmrra02_T2w.nii.gz (not available) 
  Try making some of these repositories available:
  5cdba4fc-8d50-4e89-bb0c-a3a4f9449666 -- julien@julien-macbook.local:~/code/spine-generic/data-multi-subject
  
  (Note that these git remotes have annex-ignore set: origin)
  failed
  git-annex: get: 1 failed

does git-annex know i have another local copy somewhere??

Did you clone from your filesystem?

Unfortunately I don't have extensive experience with git-annex and documentation on using it with the PR model seems to be scarce. Also the fact that the status command can glitch isn't the most reassuring thing..

Did you sync to S3 before making your PR/rebase?

[jcohenadad]

Did you clone from your filesystem?

I'm not sure I understand the question, but I did exactly as instructed here

Did you sync to S3 before making your PR/rebase?

Hum, I don't think I did. I only did a git pull on master, then went on my branch and did the rebase.

I tried the command indicated here, but it didn't help:

I'm 80% confident that this is entirely due to that "cosmetic" glitch that git-annex has. But I'm also only 80% confident in my workaround. Maybe git status was outputting those files as "added" instead of "modified", or reworded modified, or maybe it was outputting in french; there's a lot of ways my workaround could be buggy.

When it happens again paste the output of the plain git status.
