Hi all!
I'm using latest nightlies of both EGit (0.8.0.201005300830) and JGit (0.8.0.201005300828).
I have a "usability" (or "understanding") problem about cloning repositories and pushing back changes.
Scenario:
* In workspace A, I create a new project and use the "Share Project..." to "elevate" it to a local git managed one.
* In workspace B (on another computer), I clone the repo from Workspace A
* Working on files of workspace B, committing them to git repo on B
* Finally pushing HEAD back to workspace A
So far so good, no problems reported, everything green.
However, now, opening up workspace A is "strange":
1) All files that were "pushed" to repo connected with workspace A get a decorator "modified". However, the modification is the wrong way round: If I do a "Compare To git index", it looks as if I "undid" the changes in workspace A. Also, if I do a "commit" now on workspace A, the pushed changes from workspace B are "reverted"!
2) The only way to get everything "right" again in workspace A is by doing a "Reset..." with reset type "hard" - causing of course all changes that I did on workspace A in the meantime to be overridden!
In short: To me, it seems that the scenario "pushing into a local repo" is not really supported. Do you confirm or am I just misunderstanding something?
Thanks for any comments.
Regards
Kay

Got it, thanks for the link.

It is even not very common that you push to a branch which is checked out on
the remote.
A good practice is to have a dedicated branch as a target for pushes. You
can also create a new branches
on the remote with your push.

In short, if I got it right now, it is crucial for both developers to work (and push) on separate branches and then merge the respective other branch into their workspace, right?
Thanks for the hints, very appreciated!

I could reproduce that. This is clearly a bug. The push is done (the commit
is there and the HEAD is updated) but the index and the working tree are not
updated.
I'll open a bug in bugzilla.
Thanks,
Stefan

Hi Kai,
I created https://bugs.eclipse.org/bugs/show_bug.cgi?id=315205

I observed that the commit from repo B is indeed there in repo A. You can
see that in
the History View. Therefore, if you do "Reset..." with reset type "hard" on
the current
HEAD everything should be as expected..
What exactly do you mean by "all changes that I did on workspace A in the
meantime" ?
Regards,
Stefan

Hi Stefan
Thanks for your prompt reply and verification.

To be honest, I didn't verify (yet), but according to the description of a "reset type hard", that kind of reset means, that all changes in the workspace will be lost.
Example:
* workspace A is committed, no current changes
* changing File X in workspace A
* executing a hard reset
Wouldn't that mean, the changes on File X would be lost?
I assume they are. That would mean, that the workaround with "hard reset" is only acceptable, if workspace A and B are not being worked on at the same time (e.g. by two different developers).
Regards
Kay
