These modules are unmaintained upstream at the moment, but I'll
be able to help with the intended maintainer once/if CPAN
ownership is transferred. OTOH, we've been waiting for that
transfer for several years, now...
Changes I intend to make:
* EPOLLEXCLUSIVE for Linux
* remove unused fields wasting memory
* kqueue bugfixes e.g. https://rt.cpan.org/Ticket/Display.html?id=116615
* accept4 support
And some lower priority experiments:
* switch to EV_ONESHOT / EPOLLONESHOT (incompatible changes)
* nginx-style buffering to tmpfile instead of string array
* sendfile off tmpfile buffers
* io_uring maybe?

I'm using this as the cgit about-filter and source-filter
in https://80x24.org/public-inbox.git
|
|
Incomplete at the moment, but this ought to be a handy reference
for both implementers and users alike.
|
|
We will still return a 404 by default to '/' for compatibility
with users of Plack::App::Cascade or similar. Inboxes are
sorted by modification times to help users detect activity
(similar to the /$INBOX/ topic view).
New configuration options:
* publicinbox.wwwlisting - configure the listing type
* publicinbox.<name>.hide - hide a particular inbox from the listing
See changes to public-inbox-config.pod for full descriptions
of the new options.

We depend on git-http-backend for smart HTTP clone support,
however; since cgit does not support smart clones natively.
WWW.pm will be able to cascade down to this as a 404 handler in
the future.

Fixes: 285b9b4d7de53b0d ("examples/newswww.psgi: demonstrate standalone NewsWWW usage")
|
|
This is the fallback for the normal WWW endpoint.
Adding this to the top-level seems to be alright, since lynx and
w3m both understand nntp://<HOSTNAME>/<Message-ID> anyways.
If newsgroup and inbox names conflict, then consider it the
fault of the original sender.
Since NewsWWW is intended to support buggy linkifiers in mail clients,
they can interpret nntp:// URLs as http://<HOSTNAME>/<Message-ID>
Inbox ordering from the config file is preserved since
commit cfa8ff7c256e20f3240aed5f98d155c019788e3b
("config: each_inbox iteration preserves config order"),
so admins can rely on that to configure how scanning
works.

This will lookup git blobs from associated git source code
repositories. If the blobs can't be found, an attempt to
"solve" them via patch application will be performed.
Eventually, this may become the basis of a type-agnostic
frontend similar to "git show"
|
|
This will be necessary to ensure we maintain reasonable
performance when we add diff-highlighting support.
|
|
Expose the ->purge functionality of V2Writable for rewriting
git history to permanently purge messages from history. This
may be necessary for legal reasons.
Usage:
# requires ~/.public-inbox/config
public-inbox-purge --all </path/to/message-to-purge
# good for testing with unconfigured inboxes:
public-inbox-purge $INBOX_DIR </path/to/message-to-purge
|
|
We'll be using it in future admin tools, and making this
easier-to-test.
|
|
Clearly the AltId stuff was never tested for v2. Ensure
this tricky filter (which reuses Msgmap to avoid introducing
new serial numbers) doesn't trigger deadlocks SQLite due
to opening a DB for writing multiple times.
I went through several iterations of this change before
going with this one, which is the least intrusive I could
fine.
|

Remove confusing documentation around ssoma now that we
have NNTP and downloadable mbox support.
Only lightly-checked for grammar and speling, and not yet
formatting. Edits, corrections and addendums expected :>
|

I've found two examples on https://lore.kernel.org/lkml/
where the messages declared themselves to be "multipart/mixed"
but were actually plain text:
<87llgalspt.fsf@free.fr>
<200308111450.h7BEoOu20077@mail.osdl.org>
With the mboxrd downloaded, mutt is able to view them without
difficulty.
Note: this change would require reindexing of Xapian to pick up
the changes. But it's only two ancient messages, the first was
resent by the original sender and the second is too old to be
relevant.
|
|
Extracted from import_slrnspool, since some spools get converted
to mbox or what not.
|
|
This reuses some of the configuration from -watch, but remains
independent since some configurations will use -watch for some
inboxes and -mda for others.
The default remains "spamc" for -mda users so nothing changes
without explicit configuration.
Per-inbox configurations may also be supported in the future.

We must not clobber the original message string, as Email::MIME(*)
still needs it for iterating through parts in SearchIdx (but not
when handing it as a raw string to git-fast-import).
I've noticed message bodies (especially dfpre/dpost) were not
getting indexed when going through -mda (no problems with
-watch). This also did not affect v1 repos, since indexing is a
separate process for v1 and requires re-reading the data from
git.
(*) tested Email::MIME 1.937 on Debian stretch
|
|
Decrement regen_down when visiting messages that appear in %D that we
know will later be deleted. This ensures consistent message numbers are
generated no matter which commit number is on top. Allowing deletes to
propagage separately from the messages they delete without causing
problems.
The v2 trees already do this and when the indexes are deleted and
rebuilt they maintain they commit numbers.
Add a v1 version of the v2reindex test to verify that reindexing is
working properly on v1 as well as v2.

Recently I ran git --git-dir=lkml/git/1.git fsck
and it reported:
> warning in commit 299dbd50b6995c6debe2275f0df984ce697fb4cc: nulInCommit: NULL byte inthe commit object body
Which I found quite scary. Nulls in the wrong place have a bad tendency
to make programs misbehave.
It turns out someone had placed "=?iso-8859-1?q?=00?=" at the end of
their subject line. Which is the mime encoding for NULL. Email::Mime
had correctly decoded the header, and then public-inbox had simply
copied the contents of the header into the subject line of the git
commit.
To prevent that from causing problems replace nulls in such subject
lines with spaces.

Upon examination with git show --pretty=raw all of the problem commits
had a time zone that was not 4 digits long. This time zone had been
passed straight from the Date line in the email into the author line
of the commit.
Looking into that I discovered that str2time takes into account the
time zone, and was actually able to process these weird time zones.
So get the normalized time zone with strptime and convert it from
seconds from gmt to hours and minutes from gmt.

This adds a SELinux policy suitable for RHEL/CentOS 7. It assumes the
following:
- public-inbox-httpd and public-inbox-nntpd are running via systemd
on sane ports (119 and 80/8080)
- /var/lib/public-inbox is the location for mainrepos
- /var/run/public-inbox is the location for PERL_INLINE_DIRECTORY
- /var/log/public-inbox is the location for logs
- mail delivery is done via postfix-pipe or public-inbox-watch via
the provided example systemd service

I guess I forgot to include this, but I've been running

Some messages to git@vger went missing from Msgmap from old bugs
and became inaccessible via NNTP. Forcing NNTP article numbers
when the overview DB came about made the problem more visible when
reindexing old (v1) repositories as all removed spam messages
took up AUTOINCREMENT numbers again before they were removed.
Having large gaps in NNTP article numbers is not good since it
throws off NNTP clients. This does NOT prevent NNTP clients from
seeing some messages twice, but is better than having them
miss several messages entirely.
We also avoid depending on --reverse in git-log, as
git requires storing an entire commit list in memory for
--reverse, so it's cheaper to store only deleted blobs in the %D
hash since they do not live long.

While hunting duplicates, I noticed a leading '-' in some
Message-IDs as a result of RFC4648 encoding. While '-' seems
allowed by RFC5322 and URL-friendly (RFC4648), they are uncommon
and make using Message-IDs as arguments for command-line tools
more difficult. So prefix them with a datestamp to at least
give readers some sense of the age. And shorten the "localhost"
hostname to "z" to save space.
|

Since the overview stuff is a synchronization point anyways,
move it into the main V2Writable process and allow us to
drop a bunch of code. This is another step towards making
Xapian optional for v2.
In other words, the fan-out point is moved and the Xapian
partitions no longer need to synchronize against each other:
Before:
/-------->\
/---------->\
v2writable -->+----parts----> over
\---------->/
\-------->/
After:
/---------->
/----------->
v2writable --> over-->+----parts--->
\----------->
\---------->
Since the overview/threading logic needs to run on the same core
that feeds git-fast-import, it's slower for small repos but is
not noticeable in large imports where I/O wait in the partitions
dominates.
|
|
There's enough gmane links out there in wild that it makes sense
to maintain support for these mappings.
|
|
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.
|
|
While SQLite is faster than Xapian for some queries we
use, it sucks at handling OFFSET. Fortunately, we do
not need offsets when retrieving sorted results and
can bake it into the query.
For inbox.comp.version-control.git (v1 Xapian),
XOVER and XHDR are over 20x faster.
|
|
There'll be more performance-related tests in the future.
|
|
This ought to provide better performance and scalability
which is less dependent on inbox size. Xapian does not
seem optimized for some queries used by the WWW homepage,
Atom feeds, XOVER and NEWNEWS NNTP commands.
This can actually make Xapian optional for NNTP usage,
and allow more functionality to work without Xapian
installed.
Indexing performance was extremely bad at first, but
DBI::Profile helped me optimize away problematic queries.
|
|
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.
|
|
Some folks had bad mail clients which generated 3-digit years
around Y2K...
|
|
I mainly focus on -watch for mirroring busy mailing lists, but
using -mda should remain an option.
|
|
Having multiple Xapian partitions is mostly pointless after
the initial import. We can compact all the partitions into
one while keeping the skeleton separate.
|
|
This should make it easier to let users perform comparisons and
migrate to v2 if needed.
|
|
Since v2 supports duplicate messages, we need to support
looking up different messages with the same Message-Id.
Fortunately, our "raw" endpoint has always been mboxrd,
so users won't need to change their parsing tools.
|
|
Allow best-effort regeneration of NNTP article numbers from
cloned git repositories in addition to indexing Xapian Article
numbers will not remain consistent when we add purge support,
though.
|
|
This code will be shared with future mass-import tools.
|
|
Unfortunately this gives up some minor performance tweaks we
made to avoid reforking import processes.
|
|
This reduces code duplication needed for locking and
and hopefully makes things easier to understand.
|
|
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.
|
|
Since we'll need to support multiple Message-IDs anyways,
inject a new one if we hit a duplicate (or don't get one at
all).
Try to use a deterministic Message-Id for consistency, but give
up determinism and use a random Message-Id if an "attacker"
wants to prevent their message from being archived.
