Subject: [PATCH v3 0/4] upload-pack: custom allowed object filters
Date: Fri, 31 Jul 2020 16:26:21 -0400	[thread overview]
Message-ID: <cover.1596227003.git.me@ttaylorr.com> (raw)
In-Reply-To: <cover.1595468657.git.me@ttaylorr.com>

Hi,

Here's the third re-roll of my series to teach upload-pack to allow only
certain kinds of object filters. The only thing that has changed since
last time is that we now *do* look for the error messages in t5616.

Normally these error messages may or may not show up (because of the
aforementioned SIGPIPE issue in 'git clone'), but since we are cloning
from a 'file://', we can guarantee that they will appear (and can thusly
be grepped for).

Taylor Blau (4):
  list_objects_filter_options: introduce
    'list_object_filter_config_name'
  upload-pack.c: allow banning certain object filter(s)
  upload-pack.c: pass 'struct list_objects_filter_options *'
  upload-pack.c: introduce 'uploadpackfilter.tree.maxDepth'
