Some testing will be needed to see if it's worth the code
and maintenance overhead, but it seems easy-enough to get
working.

This is against lei branch @ commit
0c8106d44f317175e122744b43407bf067183175 in
https://public-inbox.org/public-inbox.git
Infrastructure stuff for reading + writing local Maildirs and a
bunch of mbox formats are done (including gz/bz2/xz support)
and it's usage should be familiar to mairix(1) users.
Infrastructure for deduplication + augmenting search results
in place and tested.
Going to skip MH and MMDF for now; but IMAP/JMAP might happen
sooner but deduplication needs low-latency.
"extinbox" renamed "external"
Basic infrastructure like PublicInbox::IPC and SharedKV
should've been done and in use ages ago... I look forward to
using them, at least.
Some DS safety fixes since lei will use it in stranger ways
than current.
Bad enough we have messages with duplicate Message-IDs, lei will
need to deal with Unsent/Drafts messages w/o Message-IDs at all!
Eric Wong (36):
import: respect init.defaultBranch
lei_store: use per-machine refname as git HEAD
revert "lei_store: use per-machine refname as git HEAD"
lei_to_mail: initial implementation for writing mbox formats
sharedkv: fork()-friendly key-value store
sharedkv: split out index_values
lei_to_mail: start atomic and compressed mbox writing
mboxreader: new class for reading various mbox formats
lei_to_mail: start --augment, dedupe, bz2 and xz
lei: implement various deduplication strategies
lei_to_mail: lazy-require LeiDedupe
lei_to_mail: support for non-seekable outputs
lei_to_mail: support Maildir, fix+test --augment
ipc: generic IPC dispatch based on Storable
ipc: support Sereal
lei_store: add ->set_eml, ->add_eml can return smsg
lei: rename "extinbox" => "external"
mid: use defined-or with `push' for uniqueness check
mid: hoist out mids_in sub
lei_store: handle messages without Message-ID at all
ipc: use shutdown(2), base atfork* callback
lei_to_mail: unlink mboxes if not augmenting
lei: add --mfolder as an option
spawn: move run_die here from PublicInbox::Import
init: remove embedded UnlinkMe package
t/run.perl: avoid uninitialized var on incomplete test
gcf2client: reap process on DESTROY
lei_to_mail: open FIFOs O_WRONLY so we block
searchidxshard: call DS->Reset at worker start
t/ipc.t: test for references via `die'
use PublicInbox::DS for dwaitpid
syscall: SFD_NONBLOCK can be a constant, again
lei: avoid Spawn package when starting daemon
avoid calling waitpid from children in DESTROY
ds: clobber $in_loop first at reset
on_destroy: support PID owner guard
