Subject: [PATCH v9 1/4] usage: make error functions a stack
Message-ID: <1405467179-16064-1-git-send-email-jacob.e.keller@intel.com>
URL: https://gitlist.dev/e/1405467179-16064-1-git-send-email-jacob.e.keller%40intel.com

```
Rename set_error_routine to be push_error_routine, and add a new
pop_error_routine. This allows temporary modifications of the error
routine over a small block of code.

Signed-off-by: Jacob Keller <jacob.e.keller@intel.com>

Renamed set_error_routine to push_error_routine in order to match the
pop_error_routine.

```
The --sort tests should use the better format for >expect to maintain
indenting and ensure that no substitution is occurring. This makes
parsing and understanding the tests a bit easier.

```
Add support for configuring default sort specification for git tags.
Command line option will override the configured value. Both methods use
the same syntax. Make use of (set/pop)_error_routine to temporarily
modify error reporting when parsing as a configuration option.

This feels a little like an abuse of the "prefix" field of vreportf, but
as you probably saw in my "for fun" patch, doing it right means
formatting into a buffer and then reformatting that (which we're
already doing again in vreportf, but less flexibly). I dunno.

At any rate, this should be marked for translation, no?

Oh, yes it probably should. It's definitely a little bit abusive of the
prefix field, but that seemed easier.

Thanks,

And i18n would automatically mean this will not work, no?  There is
no guarantee that the translation of "warning: " will be followed
directly by the translation of "tag.sort has" without any words from
variable part in all languages.

After all, it seems to me that the one in

    http://thread.gmane.org/gmane.comp.version-control.git/253346

struck the right balance among various abuses; let's use the error
reporter from that version, instead of going down this rabbit hole.

Thanks.

So is that patch series version acceptable then? Or should I spin one
again that is in that vein?

Thanks,

I do not offhand know what other changes you had in v9 since
$gmane/253346, so I'll leave it up to you.  If the only difference
is the error reporting codepath, and you are happy with what I have
in my tree

    $ git log -p --reverse -3 a93d886b9

then we can proceed with that version.  Have there been any issues
raised on that older version other than error reporting?

I'll double check.
