Subject: [PATCH 3/9] v2writable: do not clobber {shards} or {parallel} if unset
Date: Sun,  2 Feb 2020 06:52:16 +0000
Message-ID: <20200202065222.14966-4-e@yhbt.net> (raw)
In-Reply-To: <20200202065222.14966-1-e@yhbt.net>

The $jobs parameter in `public-inbox-convert' is passed to
V2Writable->init_inbox as `undef' by default, causing
parallelization to be disabled.

Instead, leave the underlying {parallel} flag untouched if
$shards is undef and do not clobber the default shard count.

This allows us to take advantage of multicore systems when
running public-inbox-convert with no command-line switches.
