The v1.2.0 is a work-in-progress, while the others are copied
out of our mail archives.

Eventually, a NEWS file will be generated from these emails and
distributed in the release tarball.  There'll also be an Atom
feed for the website reusing our feed generation code.

+
+After some 3.5 odd years of working on this, I suppose now is
+as good a time as any to tar this up and call it 1.0.0.
+
+The TODO list is still very long and there'll be some new
+development in coming weeks :>
+
+So, here you have a release:
+
+        https://public-inbox.org/releases/public-inbox-1.0.0.tar.gz
+
+Checksums, mainly as a safeguard against accidental file corruption:
+
+SHA-256 4a08569f3d99310f713bb32bec0aa4819d6b41871e0421ec4eec0657a5582216
+	(in other words, don't trust me; instead read the code :>)

I actually merged master into v2, so it's a bit backwards :P

	commit cfb8d16578e7f2f2e300f9f436205e4a8fc7f322
	Merge: 1dc0f0c 119463b

	    Merge remote-tracking branch 'origin/master' into v2

I screwed up the indexing on http://hjrcffqmbrq6wope.onion/git/
so that's still going, but I think I was able to update the rest
of them (including the heavily trafficked non-.onion) w/o downtime.

The mirror at http://czquwvybam4bgbro.onion/git/ has been running
the v2 code for over a week, now.

Thanks to the Linux Foundation for funding this work.  Will still
need to make some documentation updates and such.

* [PATCH 3/4] v2: support incremental indexing + purge
  2018-04-04 21:24  7% [PATCH 0/4] incremental indexing support for mirrors Eric Wong (Contractor, The Linux Foundation)

  To: meta

This is important for people running mirrors via "git fetch",
as they need to be kept up-to-date.  Purging is also now
supported in mirrors.

The short-lived "--regenerate" option is gone and is now
implicitly enabled as a result.  It's still cheap when
article number regeneration is unnecessary, as we track
the range for each git repository.

* [PATCH 0/4] incremental indexing support for mirrors

  0 siblings, 1 reply; 5+ results
From: Eric Wong (Contractor, The Linux Foundation) @ 2018-04-04 21:24 UTC (permalink / raw)
  To: meta

Incremental indexing is necessary for people running mirrors
via "git-fetch", but not for people running inboxes with -watch
or -mda.

There's also bugfix for the corner case where several messages
share a to-be-removed Message-ID.

Eric Wong (Contractor, The Linux Foundation) (4):
  init: s/GIT_DIR/REPO_DIR/ in usage
  import: rewrite less history during purge
  v2: support incremental indexing + purge
  v2writable: do not modify DBs while iterating for ->remove
