Hi all!
Now, when preparations from
[RFC v5 000/126] error: auto propagated local_err
https://lists.gnu.org/archive/html/qemu-devel/2019-10/msg02771.html
https://src.openvz.org/scm/~vsementsov/qemu.git #tag up-auto-local-err-v5
, after some iterations, are finally merged, let's proceed with the
rest. Sorry for a big delay on my part.
As a first step, I decided to take subsystems, each of them covered by
one patch, which get r-b/a-b marks by maintainer of the subsystem in v5.
v6 is available at
https://src.openvz.org/scm/~vsementsov/qemu.git #tag
up-auto-local-err-partI-v6
Changes v5->v6:
01: use errp name for the parameter, add assertion
02: add a lot of text information, drop Eric's r-b.
no semantic changes.
03: add more comments
skip functions with pattern error_append_.*_hint in name
make errp identifier, to match any name of Error ** paramter
some other improvements
04: only commit message changed,
keep Philippe's r-b
05: new, manual update for hw/sd/ssi-sd
06: only commit message changed,
keep Philippe's r-b
07: only commit message changed,
keep Philippe's r-b
08: local_parse_opts() changed, so patch changed in this
function, drop a-b mark
also, indentation fixed, by improvement in coccinelle script
09: only commit message changed,
keep Stefan's r-b
10: commit message and a bit of context changed, still seems
valid to keep Eric's r-b
11: add new hunk: hw/pci-host/xen_igd_pt.c, so, drop r-b
also, indentation fixed, by improvement in coccinelle script
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]$' | \
xargs spatch \
--sp-file scripts/coccinelle/auto-propagated-errp.cocci \
--macro-file scripts/cocci-macro-file.h \
--in-place --no-show-diff --max-width 80
Note, that in each generated commit, generation command is the only
text, indented by 8 spaces in 'git log -1' output, so, to regenerate all
commits (for example, after rebase, or change in coccinelle script), you
may use the following command:
git rebase -x "sh -c \"git show --pretty= --name-only | xargs git checkout HEAD^ -- ; git
reset; git log -1 | grep '^ ' | sh\"" HEAD~7
Which will start automated interactive rebase for generated patches,
which will stop if generated patch changed
(you may do git commit --amend to apply updated generated changes).
Note:
git show --pretty= --name-only - lists files, changed in HEAD
git log -1 | grep '^ ' | sh - rerun generation command of HEAD
Check for compilation of changed .c files
git rebase -x "sh -c \"git show --pretty= --name-only | sed -n 's/\.c$/.o/p' | xargs make
-j9\"" HEAD~7
