[PATCH] git: show more context info on failures

[PATCH] git: show more context info on failures

[Eric Wong]

I'm seeing "read: Connection timed out" from in my syslog from
-httpd.  The fail() calls in PublicInbox::Git seems to be the
only code path of ours which could trigger it...

ETIMEDOUT shouldn't happen on pipes, only sockets; and all of
our socket operations are non-blocking.  So this could be
cgit-wwwhighlight-filter.lua, but that's connecting over
localhost, though on fairly loaded HW.
