[PATCH v12 0/8] error: auto propagated local_err part I |

To speed things up, I'm taking the liberty to respin Vladimir's series
with my documentation amendments.
After my documentation work, I'm very much inclined to rename
ERRP_AUTO_PROPAGATE() to ERRP_GUARD(). The fact that it propagates
below the hood is detail. What matters to its users is that it lets
them use @errp more freely. Thoughts?
Based-on: Message-Id: <20200707160613.848843-1-armbru@redhat.com>
Available from my public repository https://repo.or.cz/qemu/armbru.git
on branch error-auto.
v12: (based on "[PATCH v4 00/45] Less clumsy error checking")
01: Comments merged properly with recent commit "error: Document Error
API usage rules", and edited for clarity. Put ERRP_AUTO_PROPAGATE()
before its helpers, and touch up style.
01-08: Commit messages tweaked
Vladimir's cover letter for v11:
v11: (based-on "[PATCH v2 00/44] Less clumsy error checking")
01: minor rebase of documentation, keep r-bs
02: - minor comment tweaks [Markus]
- use explicit file name in MAINTAINERS instead of pattern
- add Markus's r-b
03,07,08: rabase changes, drop r-bs
v11 is available at
https://src.openvz.org/scm/~vsementsov/qemu.git #tag
up-auto-local-err-partI-v11
v10 is available at
https://src.openvz.org/scm/~vsementsov/qemu.git #tag
up-auto-local-err-partI-v10
In these series, there is no commit-per-subsystem script, each generated
commit is generated in separate.
Still, generating commands are very similar, and looks like
sed -n '/^<Subsystem name>$/,/^$/{s/^F: //p}' MAINTAINERS | \
xargs git ls-files | grep '\.[hc]$' | \
xargs spatch \
--sp-file scripts/coccinelle/auto-propagated-errp.cocci \
--macro-file scripts/cocci-macro-file.h \
--in-place --no-show-diff --max-width 80
Note, that in each generated commit, generation command is the only
text, indented by 8 spaces in 'git log -1' output, so, to regenerate all
commits (for example, after rebase, or change in coccinelle script), you
may use the following command:
git rebase -x "sh -c \"git show --pretty= --name-only | xargs git checkout
HEAD^ -- ; git reset; git log -1 | grep '^ ' | sh\"" HEAD~6
Which will start automated interactive rebase for generated patches,
which will stop if generated patch changed
(you may do git commit --amend to apply updated generated changes).
Note:
git show --pretty= --name-only - lists files, changed in HEAD
git log -1 | grep '^ ' | sh - rerun generation command of HEAD
Check for compilation of changed .c files
git rebase -x "sh -c \"git show --pretty= --name-only | sed -n 's/\.c$/.o/p' |
xargs make -j9\"" HEAD~6
