Defect #5357
openGit: SCM revisions ordered by date/time (should be reverse commit order)
Added by Pieter Smith over 14 years ago. Updated about 13 years ago.
0%
Description
The repository browser displays the commit history sorted by date/time. When developers are working in different time-zones (or have a badly adjusted PC clocks), the commit sequence gets all jumbled up in the repository view.
Reproduction:- Commit something to a GIT repo.
- Set PC clock to <today> - <1 day>.
- Commit something else.

Same issue as #3567.
"order by date/time" is only valid for centralized system like CVS or Subversion.
I have a patch, sort-changesets-by-id.diff, to fix this issue, but which is yet well tested.
Updated by Pieter Smith over 14 years ago
Thanks, but your changeset does appear to solve the problem for a GIT repo. It did however provide me with enough info to solve it myself:
sort-changes-by-id-for-git.diff
It appears that similar changes will have to be applied to ./test/unit/repository_git_test.rb as well, but I am not familiar enough with the unit test infrastructure to make these changes.

- With the initial fetch, redmine adds the changesets in reverse commit order.
- When additional changesets are imported, they are added to the back of the table, also in reverse commit order.
- Sorting by changesets.id therefore results in a discontinuity
I tried to reverse the order with which changesets are added to the database by using the :reverse option of scm.revisions(), but all the other mechanisms use the changesets.committed_on field to determine if something is new, so new changesets are not imported resulting in changeset fetch deadlocks.

Not true. The git log --help does not seem to be accurate (and does not make sense either). Here is a clear example of a log pulled from GIT (git log --date-order and git log produces the same results):

Hmm, I'll see it later how git considers, but git-changeset-order-workaround.diff may partially fix the problem. (though I'm not sure.)
It changes the insertion order to be "ORDER BY id" as possible. (so please run clear_changesets
to regenerate changesets table, and apply also sort-changesets-by-id.diff patch)
Note: Git backend checks the last 7-day logs everytime calling fetch_changesets.
Then deletes disappeared changesets from database, and finally inserts missing ones.

Thank you!
Further testing is needed, but these two patches (sort-changesets-by-id.diff and git-changeset-order-workaround.diff) appear to fix the issue. Will this be incorporated in a near-future release, or will I have to patch future versions?
P.S. How should I run clear_changesets
? This didn't work:
@ruby script/runner "Repository.clear_changesets" -e productionI deleted the contents of the changesets table in the MySQL database to test this, but I would prefer not to circumvent the application by messing with the database.

Hi, thank you for testing it!

I'm not sure but since it requires to refetch all changesets, it might be harder to be merged into Redmine release.
Anyway, I need to understand more about Git. (I mostly use Mercurial and its Hg-Git extension.)
P.S. How should I run
clear_changesets
?
Oops! I completely misread the comment of repository/git.rb saying "The repository can still be fully reloaded by calling #clear_changesets."
There seems no way to run it from command-line.
You can regenerate changesets table by: 1. delete repository from settings tab; 2. recreate the same repository, though it's really indirect way. :)

Ah, but I've just tried minimizing the impact of #4455 patch, to make a difference only to mercurial backend. ;)
As I said before, my workaround patch for git requires database regeneration. I'm not sure how the maintainers and redmine+git users think, though, it sounds awful to me.

No, this is not related. The problem here is that redmine assumes "younger" revisions to be the "newest", which isn't the case with git. The commit date in git is just metadata, it's neither authoritative nor an indication of the ordering of the revisions. The revision order in git is provided only by the linked list nature of revisions, i.e. a revision holds a reference to its parent revision, which in turn holds a reference to its parent, and so on.
This discrepancy between "redmine assumes commit dates in consecutive commits always increases" and "the commit date in git is just metadata" is I think the problem, but that's one that will take more work than "just" fixing the git adapter.

So they are ordered by database insertion instead of commit date, still a workaround rather than a solution.
(and don't get me wrong: I appreciate the work you do here, but I think it goes in the wrong direction)

Rebased multi revisions CommitDate

So, ordering with CommitDate

I'm far away being a git expert but I think rebasing on a public "offical" repository is evil anyway. Please see git-rebase(1) NOTES and RECOVERING FROM UPSTREAM REBASE. I'm not sure if this could be fixed in redmine with reasonable efforts.

Yes. In Git and Mercurial, rebasing and history editing on public repository is rare case.
But, rebaseing and history editing on private repository and pushing these revisions to public repository is popular.
