This makes some of our code less noisy by reducing the
amount of pack('H*', ...) use.
|
|
The default value is worthless to us and git functions fine
without the file. public-inbox-init will create a useful one
in the next change.
|

Since completely purging blobs from git is slow, users may wish
to index messages in Maildirs (and eventually other local
storage) without storing data in git.
Much code from LeiImport and LeiInput is reused, and a new dummy
FakeImport class supplies a non-storing $im->add and minimize
changes to LeiStore.
The tricky part of this command is to support "lei import"
after a message has gone through "lei index". Relying on
$smsg->{bytes} == 0 (as we do for external-only vmd storage)
does not work here, since it would break searching for "z:"
byte-ranges when not using externals.
This eventually required PublicInbox::Import::add to use a
SharedKV to keep track of imported blobs and prevent
duplication.

init.defaultBranch expects a branch name, not a fully qualified ref.
git-init prepends "refs/heads/" automatically and unconditionally.
PublicInbox::Import::default_branch, however, incorrectly passes on
the init.defaultBranch value as is, leading to it being used in spots
where a fully qualified ref is required. For example, with an
init.defaultBranch value of "master", public-inbox-index for a v2
repository would lead to an all.git repository where HEAD's content is
"ref: master" instead of "ref: refs/heads/master".
Prepend "refs/heads/" to the incoming init.defaultBranch value.
Fixes: 7c2f36de2fb49dd7 (import: respect init.defaultBranch)

We need a stable fallback time for digest2mid in the presence
of messages without Received/Date headers. Furthermore, we
must avoid using uninitialized smsg->{mid} when parsing
References for draft replies.
|
|
Keyword storage for external-only messages was preventing
messages from being explicitly imported. Teach lei_store
to vivify keyword-only entries into fully-indexed messages
on import.
|
|
Apparently this feature is only in Perl 5.12+, and we're
still on Perl 5.10.
|
|
This could lead to bad results when doing ls-tree -z
for v2 import in case there's multiple files. In any case,
the `local $/ = "\0"' in Import.pm is also eliminated to
reduce potential confusion and surprises.
|
|
This avoids a zombie if another step of the event loop
takes too long.
|
|
We don't need to be keeping the raw message around after it hits
git. Shard work now relies on Storable (or Sereal) and all of
the indexing code relies on the Email::MIME-like API of Eml to
access interesting parts of the message.
Similarly, smsg->{raw_bytes} is no longer carried around and we
do the CRLF adjustment when setting smsg->{bytes}.
There's also a small simplification to t/import.t while
we're in the area to use xqx instead of spawn/popen_rd.
|
|
This saves us a few lines of code, but also prevents misreaping
by sibling processes.
|
|
GIT_CONFIG is set by -convert, and user may have it set
for other reasons. In either case, it conflicts with
any any attempt to use `git config --global` so we have
to unset it.
This fixes t/multi-mid.t under TEST_RUN_MODE=0

Using "make update-copyrights" after setting GNULIB_PATH in my

It seems like a more logical place for it, but we'll favor the
newly-added xsys_e() in tests for BAIL_OUT use.
|
|
It may be helpful to identify the source of messages
and perhaps avoid conflicting history.
On the other hand, this may be a terrible idea for users who
move portable storage (e.g. USB sticks) across computers...
|

This matches git v2.28.0+ behavior in case users prefer
a different name.

Those git commands can fail and git->qx will set $? when it
fails. There's no need for the extra indirection of the @ret
array, either.
Improve git->qx coverage to check for $? while we're at it.

Still unstable, this builds off the equally unstable extindex :P
This will be used for caching/memoization of traditional mail
stores (IMAP, Maildir, etc) while providing indexing via Xapian,
along with compression, and checksumming from git.
Most notably, this adds the ability to add/remove per-message
keywords (draft, seen, flagged, answered) as described in the
JMAP specification (RFC 8621 section 4.1.1).
We'll use `.' (a single period) as an $eidx_key since it's an
invalid {inboxdir} or {newsgroup} name.
|

It's actually supported by mutt, dovecot[1], and likely some other
software to augment the Status: header. While dovecot doesn't
expose X-Status to clients, mutt will write 'A' (answered) and
'F' to X-Status (but not T (draft)).
So we'll drop it like we do Status since it's not suitable for
public mail, but stick it in an @UNWANTED_HEADERS array will
allow us to configure an override if needed.

This will help with eventual git SHA-256 transitions.

This should further mitigate lock contention problems
when -watch is configured to watch on a Maildir for spam
while performing a large NNTP import.
There is now a small risk a message won't get removed because if
it's in the current (uncommitted) fast-import batch, but
unlikely given the batch size is now only 10 messages.
If a that small window is hit, flipping the \Seen flag
(e.g. marking it unread, and then read again) will trigger
another removal attempt via IMAP or Maildir.
|

We used ->header_obj in the past as an optimization with
Email::MIME. That optimization is no longer necessary
with PublicInbox::Eml.
This doesn't make any functional difference even if we were to
go back to Email::MIME. However, it reduces the amount of code
we have and slightly reduces allocations with PublicInbox::Eml.
|

v?fork failures seems to be the cause of locks not getting
released in -watch. Ensure lock release doesn't get skipped
in ->done for both v1 and v2 inboxes. We also need to do
everything we can to ensure DB handles, pipes and processes
get released even in the face of failure.
While we're at it, make failures around `git update-server-info'
non-fatal, since smart HTTP seems more popular anyways.
v2 changes:
- spawn: show failing command
- ensure waitpid is synchronous for inotify events
- teardown all fast-import processes on exception,
not just the failing one
- beef up lock_release error handling
- release lock on fast-import spawn failure
|
|
This is a step which makes our use of abbreviations more
consistent when referring to PublicInbox::Inbox objects.
We'll also be reducing the number of redundant fields
in SearchIdx and V2Writable code paths to make the
object graph easier-to-follow.
|
|
In case this ends up in the same process as Mbox::msg_hdr,
it can reduce memory use by sharing the cache key in
PublicInbox::Eml::re_memo
|
|
We only support Unix-like platforms where binmode (":raw") is
the default anyways, and v5.10 semantics means it won't do
unicode_strings (unlike v5.12). So save some lines of code.
|
|
It's cheaper to check for duplicates than run `spamc'
repeatedly when rechecking. We already do this for
v1 with by using the "ls" command with fast-import,
but v2 requires checking against over.sqlite3.
|
|
We can reduce the amount of platform-specific code by always
relying on IN_MODIFY/NOTE_WRITE notifications from lock release.
This reduces the number of times our read-only daemons will
need to wake up when -watch sees no-op message changes
(e.g. replied, seen, recent flag changes).
|
|
NNTP and IMAP both require CRLF conversions on the wire.
They're also the only components which care about
$smsg->{bytes}, so store the CRLF-adjusted value in over.sqlite3
and Xapian DBs..
This will allow us to optimize RFC822.SIZE fetch item in IMAP
without triggering size mismatch errors in some clients' default
configurations (e.g. Mail::IMAPClient), but not most others.
It could also fix hypothetical problems with NNTP clients that
report discrepancies between overview and article data.
|
|
This will eventually replace the __hdr() calling methods and
eradicate {mime} usage from Smsg. For now, we can eliminate
PublicInbox::Smsg->new since most callers already rely on an
open `bless' to avoid the old {mime} arg.
|
|
First, prefer the leaner "parent" module over the heavy "base"
module to establish ISA relationships, since "base" is only
needed for "fields".
The "//" and "//=" operators allow us simplify our code and fix
minor bugs where a value of "0" was disallowed. Yes, we'll
allow "0" as an email address, too, since some twisted BOFH
could theoretically use it as a local user name.
Going forward, we'll also be avoiding "use warnings" and
instead rely on `-w' in the shebang.
|
|
In our inbox-writing code paths, ->getline as an OO method may
be confused with the various definitions of `getline' used by
the PSGI interface. It's also easier to do: "perldoc -f readline"
than to figure out which class "->getline" belongs to (IO::Handle)
and lookup documentation for that.
->print is less confusing than the "readline" vs "getline"
mismatch, but we can still make it clear we're using a real
file handle and not a mock interface.
Finally, functions are a bit faster than their OO counterparts.
|
|
To avoid confusing future readers and users, recommend
PublicInbox::Eml in our Import POD and refer to PublicInbox::Eml
comments at the top of PublicInbox::MIME.
mime_load() confined to t/eml.t, since we won't be using
it anywhere else in our tests.
|
|
The old name may be confused with "Content-ID" as described in
RFC 2392, so use an alternate name to avoid confusing future
readers.
|
|
We no longer load or use Email::MIME outside of comparison
tests.
|
|
PublicInbox::Eml has enough functionality to replace the
Email::MIME-based PublicInbox::MIME.
|
|
Prefer the "ID" capitalization since it seems to to be the
preferred capitalization in RFC 5322.
In theory, this allows the interpreter to deduplicate the string
internally (I haven't checked if it does).
Unfortunately, there's too many instances of "Message-Id" in the
tests to be worth changing at this point.
|
|
Even on systems with Inline::C spawn(), this cuts a primed
"make check-run" time by 2-3% on Linux, and roughly 5-7% on
FreeBSD when using vfork-enabled spawn.
I doubt anybody cares: this omits the sample hooks and some
empty and useless-for-us or obsolete directories created by
git-init(1).
|
|
Allowing ->init_bare to be used as a method saves some
keystrokes, and we can save a little bit of time on systems with
our vfork(2)-enabled spawn().
This also sets us up for future improvements where we can
avoid spawning a process at all.
|
|
We can finally get rid of the awkward, ad-hoc use of V2Writable,
SearchIdx, and OverIdx args for passing {cotime} and {autime}
between classes.
We'll still use those git time fields internally within
V2Writable and SearchIdx for (re)indexing, but that's not
worth avoiding as a fallback.
|
|
While v2 indexing is triggered immediately after writing the
commit to the git repository, there may be a gap between when
PublicInbox::Import generates a timestamp and when
PublicInbox::SearchIdx sees the message. So follow the mirror
indexing behavior and take the to-be-indexed (time|date)stamps
directly from the git commit.
|
|
Some strange "From:" lines will cause Email::Address::XS to
leave '<' (and presumably '>') in the address which
git-fast-import won't accept even if quoted. Workaround this
problem by deleting '<' and '>' the same way we delete them for
the ident name.

I didn't wait until September to do it, this year!
|
|
popen_rd accepts arbitrary redirects, so we can reuse its
code to setup the pipe end we want to read, saving each
caller a few lines of code compared to calling pipe+spawn.
|
|
Most spawn and popen_rd callers die on failure to spawn,
anyways, and some are missing checks entirely. This saves
us a bunch of verbose error-checking code in callers.
This also makes popen_rd more consistent, since it already
dies on pipe creation failures.
|
|
There's a bunch of leftover "require" and "use" statements we no
longer need and can get rid of, along with some excessive
imports via "use".
IO::Handle usage isn't always obvious, so add comments
describing why a package loads it. Along the same lines,
document the tmpdir support as the reason we depend on
File::Temp 0.19, even though every Perl 5.10.1+ user has it.
While we're at it, favor "use" over "require", since it it gives
us extra compile-time checking.
|
|
Found by codespell, there's a few more in comments and some
debatable ones, but user-facing stuff is more important.
|
|
We can save callers the trouble of {-hold} and {-dev_null}
refs as well as the trouble of calling fileno().
|
|
run_die() doesn't require an $env arg, so there's no
point passing "undef" to it.
