Cleanup temporary directories on common termination signals
(INT, HUP, PIPE, TERM), but only if it's not in the process
of being committed via rename() sequence.
|
|
Emit information about reindexing git revision ranges when used
with xcpdb. Additionally, distinguish Xapian copy output from
v2 git epoch counting by increasing directory context info.
For now, v1 batches batches are emitted. v2 indexing is still
missing progress reporting for batches, as the data structures
for reindexing would benefit from a refactoring, first.
This does not currently affect the use of public-inbox-index,
but may in the future.
|
|
`warn' is reserved for actual warnings, as it respects
$SIG{__WARN__} and we rely on that override to print
message context information when we are indexing.
|
|
It is no longer a wrapper around copydatabase(1), since
copydatabase did not recover from DatabaseModifiedError.
|
|
By creating temporary directories as deep as possible,
we can allow v2 repositories to have `xap$SCHEMA_VERSION'
(e.g. `xap15') reside on a separate FS.
We also check st_dev ahead-of-time to avoid doing work which
will fail with EXDEV. Of course, another process may still
move/change things around.
|
|
Running a full "public-inbox-index --reindex" in parallel
with "public-inbox-xcpdb" on the same inbox can still cause
problems, though.
|
|
Copying an entire Xapian DB is horribly slow whether it's done
via Perl or copydatabase(1). So displaying some progress
indication is good for user experience.
While we're at it, prefix xapian-compact output, too; since
parallel processes end up clobbering each other.
|
|
Copying an entire Xapian DB takes a long time, so update our
reindexing code to support partial reindexing, snapshot the
pre-copydatabase git revisions, perform the lengthy copy,
and do a partial reindex when the copy + renames are done.
|
|
This is preparation to to support partial reindexing
|
|
To minimize the delay on active inboxes, it's actually ideal to
run xapian-compact at the end of the per-partition cpdb process;
since the new DB isn't accessible yet and so we don't have to
deal with lock contention with -mda or -watch processes. The
downside is temporary file overhead (3x instead of 2x) required.
|
|
By avoid copydatabase(1) entirely, we can make further changes
to avoid locking the entire inbox for a long operation and
switch to fine-grained locking.
|
|
We will be reindexing after copydatabase
|
|
We move the old directory into the new directory, so avoid the
situation where a bug or error could cause the tempdir cleanup to run
and destroy both our old and new directories.
|
|
copydatabase(1) is an existing Xapian tool which is the
recommended way to upgrade existing DBs to the latest Xapian
database format (currently "glass" for stable/released
versions). Our use of Xapian relies on preserving document IDs,
so we'll wrap it like we do xapian-compact(1) and use the
"--no-renumber" switch.
I could not name the tool "public-inbox-copydatabase" since it
would be ambiguous as to which DB it's actually copying. So, I
abbreviated the suffix to "xcpdb" (Xapian CoPy DataBase), which
I hope is acceptable and unambiguous.
|
|
copydatabase(1) is exceptionally noisy and it's output is
confusing when run in parallel. Support redirects at least, and
env while we're at it to give us future options.
We can also stuff a -jobs parameter into the options to limit
parallelism since it can be useful for low-priority upgrade
jobs.
|
|
Both of these index-affecting commands should work similarly
on the command-line.
public-inbox-index no longer complains about unconfigured
~/.public-inbox/config; but often I found myself being
annoyed by that, anyways...
|
|
Port public-inbox-compact(1) over to using it, and we will need
to wrap copydatabase(1) to ease glass migrations, too.
|
|
This is assuming nobody uses flint or earlier, anymore;
as flint predates the existence of this project.
|
|
We're going to need copydatabase, too
|
|
In retrospect, introducing V1Writable was unnecessary and
InboxWritable->importer is in a better position to abstract
away differences between v1 and v2 writers.
So teach InboxWritable to initialize inboxes and get rid
of V1Writable.
|
|
Can't run the test if the required Xapian tools are missing.

* ds-cleanup:
DS: warn on deprecations
DS: remove IPPROTO_TCP import
DS: drop $VERSION var
DS: remove support OtherFds code
DS: get rid of unused methods and aliases
|
|
Enabling deprecation warnings didn't seem to have any
noticeable effects with "perl -w -c", so whatever reason
Danga had for it is long irrelevant.
|
|
Unlike Danga::Socket, we do not support TCP_CORK, either
|
|
It was only relevant to Danga::Socket.
|
|
It's easy enough to wrap FDs in classes that can use
all of the functionality of the event loop, not just
the read-only interface AddOtherFds provided.
|
|
"make syntax" is clean, now
|
|
It's a non-standard package on CentOS-7, actually; and we
shouldn't bloat the PSGI server by loading a module which
isn't strictly needed.
|
|
Tested on an amd64 chroot built with rinse 3.4
|
|
None of the Search::Xapian-dependent stuff works without DBI
and DBD::SQLite.
There are no plans to support Xapian w/o DBD::SQLite since
SQLite is more common and less resource-intensive than Xapian.
|
|
git < 2.5.0 was missing --git-path support. This means any
users relying on some rare environment variables will need git
2.5.0+
|
|
This test was not disabled properly for ancient versions of
git without get-mark support.
|
|
"git config" did not preserve permissions of the config file it
modifies prior to git 2.1.0, so workaround that.
|
|
* origin/xap-optional:
admin: improve warnings and errors for missing modules
searchidx: do not create empty Xapian partitions for basic
lazy load Xapian and make it optional for v2
www: use Inbox->over where appropriate
nntp: use Inbox->over directly
inbox: add ->over method to ease access
|
|
We only compress in OverIdx, now; since we no longer do overview
stuff in Xapian (and Xapian compresses document data, anyways).
|
|
Consolidate subject handling in the add function to make it easier to
read and understand.

This allows searching for terms with "+" in them properly.
|
|
This was buggy and was causing non-diff text to have extra
leading spaces. The diff parsing code needs to be cleaned up,
so this will be fixed, later.
This reverts commit 1a67b91c1326efa372d1ec957e2494849d894f0b.
|
|
There probably needs to be an option to enable this
independently of indexlevel; but for now this is
the safest option.
And, as I discovered during the development of the
indexlevel option, Xapian does a pretty good job of
finding phrases without position data, anyways.
|
|
"git format-patch --interdiff" and similar can prefix diffs
with leading white space. Teach our diff parser to account
for it and set appropriate CSS classes for them.
|
|
It's only useful for a corner case in long-running daemons when
an admin decides to compact or vacuum a Xapian or SQLite DB.
As a result, other scripts should run slightly faster. For
instance, this saves about 80ms (2.710s => 2.630s) in t/mda.t
on my remote workstation.
While we're at it, make sure EvCleanup is properly require'd
in Daemon.pm and HTTP.pm and document our use of Devel::Peek.
|
|
We no longer need it since Inbox->recent hits the overview
DB instead of Xapian
|
|
Preventative measures; since marketing is almost always annoying
to me. And trying to avoid unintended consequences.
|
|
Since we lazy-load Xapian now, some errors may become
more cryptic or buried. Try to improve that by making
Admin show better errors.
|
|
No point in leaving a mess of empty directories when Xapian
doesn't load.
|
|
More tests work without Search::Xapian, now.
Usability issues still need to be fixed
|
|
We don't need to rely on Xapian search functionality for the
majority of the WWW code, even. subject_normalized is moved to
SearchMsg, where it (probably) makes more sense, anyways.
|
|
None of the NNTP code actually relies on Xapian, anymore.
|
|
One small step towards making installing Xapian optional for v2
and providing more WWW and NNTP functionality without it.
|
|
We only need it for tests that chdir, and maybe for ENV{PATH}
portability (dash seems fine, not sure about others).
v2: revert change to solver_git.t for FreeBSD 11.2 and document
