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.
|
|
We do not need to rewrite old commits unaffected by the object_id
purge, only newer commits. This was a state management bug :x
We will also return the new commit ID of rewritten history to
aid in incremental indexing of mirrors for the next change.
|
|
We need to ensure there is only one file in the top-level tree
at any commit so the "add; remove; add;" sequence on the same
message is detected properly.
Otherwise, git will not detect the second "add" unless
a second message is added to history.
Deletes are now stored in "d" (and not "D" or "_/D") at the
top-level, now. There's no need to have a "_" to reduce churn
as "m" and "d" should never co-exist. It's now lowercased to
make it easier-to-distinguish from "D" in git-log output.
|
|
We'll be using it in more future tests and scripts.
|
|
Purging existing messages is fairly straightforward since we can
take advantage of Xapian and lookup the git object_id with it.
Unfortunately, purging an already "removed" message (which is
no longer in Xapian) is not as easy and we'll need to expose
->purge_oids to purge by the git object_id (currently SHA-1).
Furthermore, we expire reflogs and prune in hopes a dumb HTTP
client won't get the object.
|
|
The original Message-ID is still the most important when
discussing with other recipients who do not rely on a message
flowing through public-inbox. So whatever Message-ID we use
to deduplicate internally will be secondary and less important.
All of our front-end v2 code is order-independent, so we won't
let the message count against us, that way.
|
|
This also quiets down warnings from -watch when spam training
happens on messages without Message-Id.
|
|
We want to make it clear to the code and DEBUG_DIFF users
that we do not introduce messages with unsuitable headers
into public archives.
|
|
We want to rely on Date: to sort messages within individual
threads since it keeps messages from git-send-email(1) sorted.
However, since developers occasionally have the clock set
wrong on their machines, sort overall messages by the newest
date in a Received: header so the landing page isn't forever
polluted by messages from the future.
This also gives us determinism for commit times in most cases,
as we'll used the Received: timestamp there, as well.
|
|
Reduce the places where we have duplicate logic for discarding
unwanted headers.
|
|
This reduces code duplication needed for locking and
and hopefully makes things easier to understand.
|
|
Instead of using ssoma-based locking, enable locking via Import
for now.
|
|
Hexdigests are too long and shorter Message-IDs are easier
to deal with.
|
|
This allows us to share code for generating Message-IDs
between v1 and v2 repos.
For v1, this introduces a slight incompatibility in message
removal iff the original message lacked a Message-ID AND
the training request came from a message which did not
pass through the public-inbox:
The workaround for this would be to reuse the bad message from
the archive itself.
|
|
This will allow WatchMaildir to use ->barrier operations instead
of reaching inside for nchg. This also ensures dumb HTTP
clients can see changes to V2 repos immediately.
|
|
In the future, we may store "purged" content IDs or other
uncommon stuff under "_/" of the git tree. This keeps the
top-level tree small and more amenable to deltafication.
This helps the the common case where "m" is most commonly
changed file at the top level.
Also, use 'D' instead of 'd' since it matches git's '--raw'
output format.
|
|
This makes it easier to audit deletes with "git log -p" and
prevents an unstable specification of "content_id" from being
stored in history.
This should be cost-free if done in the same partition (and even
cheaper than before as it introduces no new blobs). It does
have a higher cost across partitions, but is probably irrelevant
given the typical ham:spam ratio.
|
|
Email::Simple is slightly faster this way, and Email::MIME
and PublicInbox::MIME both wrap that.
|
|
Stopping and starting a bunch of processes to look up duplicates
or removals is inefficient. Take advantage of checkpointing
in "git fast-import" and transactions in Xapian and SQLite.
|
|
This seems like a reasonable course of action for old messages.

The first Received: header is believable since it typically
hits the user's mail server and can be treated as relatively
trustworthy. We still show the Date: in per-message (permalink)
views, which may expose users for having incorrect Date:
headers, but all the ISO YYYY-MM-DD dates we display will
match what we see.
|
|
It's easier to store everything in one array ref similar
to what our Git->check routine returns
|
|
Leaking these pipes to child processes wasn't harmful, but
made determining relationships and dataflow between processes
more confusing.
|
|
The parallelization requires splitting Msgmap, text+term
indexing, and thread-linking out into separate processes.
git-fast-import is fast, so we don't bother parallelizing it.
Msgmap (SQLite) and thread-linking (Xapian) must be serialized
because they rely on monotonically increasing numbers (NNTP
article number and internal thread_id, respectively).
We handle msgmap in the main process which drives fast-import.
When the article number is retrieved/generated, we write the
entire message to per-partition subprocesses via pipes for
expensive text+term indexing.
When these per-partition subprocesses are done with the
expensive text+term indexing, they write SearchMsg (small data)
to a shared pipe (inherited from the main V2Writable process)
back to the threader, which runs its own subprocess.
The number of text+term Xapian partitions is chosen at import
and can be made equal to the number of cores in a machine.
V2Writable --> Import -> git-fast-import
\-> SearchIdxThread -> Msgmap (synchronous)
\-> SearchIdxPart[n] -> SearchIdx[*]
\-> SearchIdxThread -> SearchIdx ("threader", a subprocess)
[* ] each subprocess writes to threader

This is too slow, currently. Working with only 2017 LKML
archives:
git-only: ~1 minute
git + SQLite: ~12 minutes
git+Xapian+SQlite: ~45 minutes
So yes, it looks like we'll need to parallelize Xapian indexing,
at least.
|
|
Wrap the old Import package to enable creating new repos based
on size thresholds. This is better than relying on time-based
rotation as LKML traffic seems to be increasing.
|
|
Despite email not existing until 1971; "Jan 1, 1970 00:00:00"
seems like a common default timestamp for some test emails
to use as a Date: header.
|
|
There's a lot of crap in archives and git-fast-import
accepts empty names and email addresses for authors
just fine.
|
|
For LKML, it appears we need an even more liberal parser than
RFC2822 date parser in git. I have not validated Date::Parse
parses dates correctly, but this at least prevents
git-fast-import(1) from choking.
|
|
Wrap "get-mark" and "checkpoint" commands for git-fast-import
while documenting/cementing parts of the API.
|
|
Call order will need to change a bit since this is going to be
tied to Xapian
|
|
We'll reuse this class in v2, but won't be utilizing
per-git-repository ssoma.lock files.
Meanwhile, stop treating ::Inbox objects as an afterthought
and allow importing name and email into them.
|
|
For machines which have never seen ssoma, they don't need the
index so stop creating it.
|
|
Using update-copyrights from gnulib
While we're at it, use the SPDX identifier for AGPL-3.0+ to
ease mechanical processing.
|
|
Sometimes an email is an innocent removal "rm" for a
misdirected, off-topic post, while most removed messages are
"spam". Allow anybody to look at history and easily distinguish
the reason for removing the message.
|
|
This seems to allow weirdly-encoded "raw" emails in
blade.nagaokaut.ac.jp/ruby/ruby-core/*
to be handled without difficulties.
|
|
This was necessary for the presence of the 0xa0 byte(*)
in the Subject: of the message at:
http://blade.nagaokaut.ac.jp/ruby/ruby-core/3220
(*) That is 0xa0, not 0x0a ("\n"), so I wonder if the
nibbles got swapped somehow.
|
|
This should fix problems with multipart messages where
text/plain parts lack a header.
cf. git clone --mirror https://github.com/rjbs/Email-MIME.git
refs/pull/28/head
In the future, we may still introduce as streaming
interface to reduce memory usage on large emails.
|
|
We should not completely kill a process if "git gc --auto"
errors out due to a warning or whatnot.
|
|
We need to prevent excessive repository growth for
public-inbox-watch and public-inbox-mda users.
|
|
We will be reusing this in the next commit, too.
|
|
This reduces duplication, slightly. We may be using it
yet again in a to-be-introduced function (or we may not
introduce it).
|
|
Not sure why or how I missed this before; but the common address
parsing routine we have should be more correct.
Add a test to ensure excessively quoted names don't make it
through, either.
|
|
We need to pass the Inbox object to SearchIdx to get altid
mappings properly for incremental imports.
TODO: use the Inbox object in more places where it makes sense
to do so.
|
|
This will allow us to release and re-acquire Xapian locks
due to the lack of FD_CLOEXEC on some FDs.
|
|
For reindexing, fresh Xapian DBs do not count as a reindex,
allowing users to blindly use --reindex on the first
run on a clean repo.
While we're at it, allow indexing to override HEAD ref for
multi-head git repos.
|
|
Callers may have localized $/ to something else, so make sure
we chomp the expected character(s) when calling chomp.
|
|
Mailing lists I watch and mirror may not have the best spam
filtering, and an extra layer should not hurt.
|
|
Because our WatchMaildir module is liberal about what
it accepts, we can potentially have messages without a
subject.
|
|
This prevents multiple update processes from stepping over
each other while called under the lock, and also allows the
new -watch process to update the index iff indexing was
desired.
