From: Karthik Nayak <karthik.188@gmail.com>
Remove unnecessary variables from ref_list and ref_item which were
used for width computation. This is to make ref_item similar to
ref-filter's ref_array_item. This will ensure a smooth port of
branch.c to use ref-filter APIs in further patches.
Previously the maxwidth was computed when inserting the refs into the
ref_list. Now, we obtain the entire ref_list and then compute
maxwidth.

This is a preperatory patch for 'roll show_detached HEAD into regular
ref_list'. This patch moves get_head_description() to the top so that
it can be used in print_ref_item().

Remove show_detached() and make detached HEAD to be rolled into
regular ref_list by adding REF_DETACHED_HEAD as a kind of branch and
supporting the same in append_ref(). This eliminates the need for an
extra function and helps in easier porting of branch.c to use
ref-filter APIs.
Before show_detached() used to check if the HEAD branch satisfies the
'--contains' option, now that is taken care by append_ref().

We check if given ref is the current branch in print_ref_list(). Move
this check to print_ref_item() where it is checked right before
printing.

Remove the error reporting variable to make the code easier to port
over to using ref-filter APIs. This variable is not required as in
ref-filter we already check for possible errors and report them.

From: Karthik Nayak @ 2015-08-22 6:51 UTC (permalink / raw)
To: git; +Cc: christian.couder, Matthieu.Moy, gitster, Karthik Nayak,
Karthik Nayak
Make 'branch.c' use 'ref-filter' data structures and make changes to
support the new data structures. This is a part of the process of
porting 'branch.c' to use 'ref-filter' APIs.
This is a temporary step before porting 'branch.c' to use 'ref-filter'
completely. As this is a temporary step, most of the code introduced
here will be removed when 'branch.c' is ported over to use
'ref-filter' APIs.
Make 'free_array_item()' of ref-filter.c a non static function. This
is used to free memory allocated to a detached head ref, before we
print other refs.

7 siblings, 1 reply; 13+ messages in thread
From: Karthik Nayak @ 2015-08-22 6:51 UTC (permalink / raw)
To: git; +Cc: christian.couder, Matthieu.Moy, gitster, Karthik Nayak,
Karthik Nayak
Make 'branch.c' use 'ref-filter' APIs for iterating through refs
sorting. This removes most of the code used in 'branch.c' replacing it
with calls to the 'ref-filter' library.
Make 'branch.c' use the 'filter_refs()' function provided by 'ref-filter'
to filter out tags based on the options set.
We provide a sorting option provided for 'branch.c' by using the sorting
options provided by 'ref-filter'.
Also remove the 'ignore' variable from ref_array_item as it was
previously used for the '--merged' option and now that is handled by
ref-filter.
The test t1430 'git branch shows badly named ref' has been changed to
check the stderr for the warning regarding the broken ref. This is
done as ref-filter throws a warning for broken refs rather than
directly printing them.
Modify documentation and add tests for the same.

Maybe the test could be renamed to 'git branch warns about badly named
ref' and maybe you could also check that "broken\.\.\.ref" is not
printed on stdout.
Thanks,
Christian.

The name change sounds reasonable, do we really need to check for it in the
stdout?

I think Christian meant "we should check in both", i.e.
git branch >output 2>error &&
grep "broken\.\.\.ref" error &&
! grep "broken\.\.\.ref" output
or something like that. That way, you are effectively specifying in
the test that badly named refs must not be included in the output,
so somebody who changes that in the future needs to justify why
including them in the output is a good idea when updating the test.

Ah! okay, I get what you're saying. Should I reroll it? Or a squash in?

Add the '--points-at' option provided by 'ref-filter'. The option lets
the user to list only branches which points at the given object.
Add documentation and tests for the same.
