git send-email -v

Hi,

when I do

$ git send-email -v --dry-run --to=me -1 /tmp/UdA2hemFfD/v-dry-run-0001-x86-microcode-Include-vendor-headers-into-.patch (body) Adding cc: Borislav Petkov (AMD) <bp@alien8.de> from line 'Suggested-by: Borislav Petkov (AMD) <bp@alien8.de>'

Subject: [PATCH v--dry-run] x86/microcode: Include vendor headers into microcode.h

Send this email? ([y]es|[n]o|[e]dit|[q]uit|[a]ll): ---

The -v and --dry-run are glued together and stuck as text after "[PATCH" in the subject.

Without -v, it works as expected, see below.

Shouldn't the option parsing error out with "-v is unrecognized option" or so?

The git version is the latest from the repo: 2.42.0.rc0.25.ga82fb66fed25

Thx.

-v is a valid option to git format-patch:

      -v <n>, --reroll-count=<n>
           Mark the series as the <n>-th iteration of the topic. The
output filenames have v<n> prepended to them, and the subject prefix
("PATCH" by
           default, but configurable via the --subject-prefix option)
has ` v<n>` appended to it. E.g.  --reroll-count=4 may produce
           v4-0001-add-makefile.patch file that has "Subject: [PATCH
v4 1/20] Add makefile" in it.  <n> does not have to be an integer
(e.g.
           "--reroll-count=4.4", or "--reroll-count=4rev2" are
allowed), but the downside of using such a reroll-count is that the
range-diff/interdiff with
           the previous version does not state exactly which version
the new interation is compared against.

it takes a required argument, and inserts "v<argument>" into the [PATCH] block to describe the version.

Typically the argument should be a number, but you happened to provide it "--dry-run". Presumably assuming that the -v means "verbose" as it might in most other applications.

In short: this is working as intended, but it is somewhat confusing that it doesn't validate the argument at all. It is intentional to allow non-numeric strings, but maybe we ought to validate that it doesn't start with -- to avoid such confusion here.

In short: -v doesn't mean verbose, it is a valid option, and while its a bit non-intuitive in this case, I think it is working as designed now.

Thanks, Jake

Aaaah.

Yap.

Yes, the non-intuitiveness is kinda confusing.

Thanks for explaining!

I think both of your points are quite reasonable here.
