[PATCH v4 0/5] Pretty formats for reflog data

Junio C Hamano wrote:

One solution to help the compiler catch this kind of semantic crash upon
merging or applying code based on the old format_commit_message() would
have been to change its function signature (or even the name), so that it
would not go unnoticed that DATE_NORMAL that happens to be "0" is silently
interpreted as (void *)0 == NULL.

Indeed, that would have been a good idea.  (I still don't fully see
the use of allowing an enum value as a pointer, but apparently the
standard's that way.)

I fixed the calls to format_commit_message(), but without changing the
function signature compared to the last patch.  I also decided not to
put in the test case; the easiest I could come up with was the
following:

-- 8< --

diff --git i/t/t5001-archive-attr.sh w/t/t5001-archive-attr.sh
index 426b319..0950527 100755
--- i/t/t5001-archive-attr.sh
+++ w/t/t5001-archive-attr.sh

-SUBSTFORMAT=%H%n
+SUBSTFORMAT=%H%ad%n
 
 test_expect_exists() {
 	test_expect_success " $1 exists" "test -e $1"
-- >8 --

which immediately fails most tests in the file because of segfaults
with the buggy series.  However, it still wouldn't catch other broken
callers, if there were any, so I left it out.

Compared to v3, I also rebased the series on current master, which
conflicted with 7f98ebc (format_commit_message(): fix function
signature, 2009-10-15) so you now need that commit to apply it.

Finally, I squashed a revert of 0a0c342 (git-stash documentation:
mention default options for 'list', 2009-10-12) into 5/5 since there
are no more default options after my patch.


Thomas Rast (5):
  Refactor pretty_print_commit arguments into a struct
  reflog-walk: refactor the branch@{num} formatting
  Introduce new pretty formats %g[sdD] for reflog information
  stash list: use new %g formats instead of sed
  stash list: drop the default limit of 10 stashes
