Git log --decorate show prefetch objects

Git log --decorate show prefetch objects

# What did you do before the bug happened? (Steps to reproduce your issue)

<on a git repository not fetch from a "long" time so you have missing 
branches and/or objects>

git maintenance run --task=prefetch

git log --oneline --decorate --all --graph

NOTE: here:
     - xxxxxxx commits are local commits,
     - yyyyyyy commits are remote commits fetch previously,
     - zzzzzzz commits are remote commits prefetch.

     * xxxxxxx (HEAD -> current-dev, origin/master, origin/HEAD) feat
     * xxxxxxx feat
     | * yyyyyyy (origin/feature) feat
     |/
     * xxxxxxx feat
     | * yyyyyyy (origin/a-fix) fix

     | * zzzzzzz feat
     | * zzzzzzz feat

     * xxxxxxx feat
     | * zzzzzzz feat
     |/
     * xxxxxxx fix


According to the git-log  documentation (cf: 
https://git-scm.com/docs/git-log#Documentation/git-log.txt---all ):

     --all Pretend as if all the refs in refs/, along with HEAD, are 
listed on the command line as <commit>.

But the --decorate (cf: 
https://git-scm.com/docs/git-log#Documentation/git-log.txt---decorateshortfullautono 
):

     --decorate
     Print out the ref names of any commits that are shown. If short is 
specified,
     the ref name prefixes refs/heads/, refs/tags/ and refs/remotes/ 
will not be printed.
     [...]
     The option --decorate is short-hand for --decorate=short.

Documentation of maintenant prefetch (cf: 
https://git-scm.com/docs/git-maintenance#Documentation/git-maintenance.txt-prefetch 
):

     The prefetch task updates the object directory with the latest 
objects from all registered remotes.
     For each remote, a git fetch command is run.
     The configured refspec is modified to place all requested refs 
within refs/prefetch/.
     Also, tags are not updated.



# What did you expect to happen? (Expected behavior)

I would have prefer this output (prefetch not shown):

     * xxxxxxx (HEAD -> current-dev, origin/master, origin/HEAD) feat
     * xxxxxxx feat
     | * yyyyyyy (origin/feature) feat
     |/
     * xxxxxxx feat
     | * yyyyyyy (origin/a-fix) fix
     |/
     * xxxxxxx fix
     * xxxxxxx feat
     * xxxxxxx fix

Or this output (prefetch properly decorated):

     * xxxxxxx (HEAD -> current-dev, origin/master, origin/HEAD) feat
     * xxxxxxx feat
     | * yyyyyyy (origin/feature) feat
     |/
     * xxxxxxx feat
     | * yyyyyyy (origin/a-fix) fix
     |/
     * xxxxxxx fix
     | * zzzzzzz (refs/prefetch/remotes/origin/anotherfeat) feat
     | * zzzzzzz feat
     | * zzzzzzz feat
     |/
     * xxxxxxx feat
     | * zzzzzzz (refs/prefetch/remotes/origin/anotherotherfeat) feat
     |/
     * xxxxxxx fix


# What happened instead? (Actual behavior)

Prefetch object are return and not properly decorated.



# What's different between what you expected and what actually happened?

I would have preferd prefetched objects not displayed

I do not use the prefetch stuff, but unfortunately the person who
was most familiar with "maintenance" are no longer active on this
list, so let me take a crack.

I think your complaint is that "--all" really means "all", not just
"heads" and "tags" but also includes "prefetch", while the prefetch
hierarchy is not included in the "--decorate" sources.

What does

    $ git log --oneline --branches --tags --decorate --graph

show, and is it closer to what you expected (note: this is not a
direct suggestion of a workaround---trying to gauge what the
direction is to move forward)?

Thanks.

Indeed, I missed the --branches (and --remotes) options; they do a 
better job in my case.

Maybe --all have a "legacy behaviour" so it's on me to move to new and 
better options.

Thanks.
