Subject: [Re-send PATCH v7 00/12] Deprecate .git/info/grafts
Date: Sun, 29 Apr 2018 00:47:30 +0200 (DST) [thread overview]
Message-ID: <cover.1524955439.git.johannes.schindelin@gmx.de> (raw)

[Resent the cover letter, as I did not see it on public-inbox...]
It is fragile, as there is no way for the revision machinery to say "but
now I want to traverse the graph ignoring the graft file" e.g. when
pushing commits to a remote repository (which, as a consequence, can
miss commits).
And we already have a better solution with `git replace --graft <comit>
[<parent>...]`.
Changes since v6:
- Made --convert-graft-file issue a mere warning (instead of an error) when
a graft leaves the parents unchanged, and is hence unnecessary.
- Modified the regression test for --convert-graft-file to succeed even when
the GPG prerequisite is unmet (thanks, Gábor!).
- Reassured by Stefan's feedback, I refrained from reinstating the contrib/
script.
Johannes Schindelin (12):
argv_array: offer to split a string by whitespace
commit: Let the callback of for_each_mergetag return on error
replace: avoid using die() to indicate a bug
replace: "libify" create_graft() and callees
replace: prepare create_graft() for converting graft files wholesale
replace: introduce --convert-graft-file
Add a test for `git replace --convert-graft-file`
Deprecate support for .git/info/grafts
filter-branch: stop suggesting to use grafts
technical/shallow: stop referring to grafts
technical/shallow: describe why shallow cannot use replace refs
Remove obsolete script to convert grafts to replace refs
