Base-85 binary patches generated by git lead to many false
positives, so skip over gibberish words which may occur in them.
To avoid regressions in search results, continue to allow
searching for exact size matches (via "literal $SIZE") and the
phrase "GIT binary patch" for the mere presence of a binary
patch.
|
|
This allows easy searching via patch-id from a git commit.
Currently, abbreviations are not supported, and it seems
needless to support them since AFAIK (git) doesn't generate
nor resolve abbreviated patch-ids anywhere.

In the container used to build packages of the GNU Guix distribution, PID 1
runs as the same user as the test so this spawn that should fail actually
succeeds.
Fix the problem by going through different PIDs and picking one that
either doesn't exist or we aren't allowed to signal.

It's probably not a perfect match for RFC 6068 atm, but perfect

Since we'll be adding POP3 support as our 4th network protocol;
asking admins to run yet another daemon on top of existing
-httpd, -nntpd, -imapd is a maintenance burden and a waste of
memory.
The goal of public-inbox-netd is to be able to replace all
existing read-only daemons with a single process to save memory
and reduce administrative overhead; hopefully encouraging more
users to self-host their own mirrors.
It's barely-tested at the moment. Eventually, multiple
PI_CONFIG and HOME directories will be supported, as are
per-listener .psgi config files.

This enables lei-daemon to work without Inline::C nor
Socket::MsgHdr installed. Prior to this, only the `lei' client
was using the pure Perl implementation. Either C implementation
is still marginally faster, however.
|
|
Apparently leaving {sqlite_unicode} unset isn't enough, and
there's subtle differences where BLOBs are stored differently
than TEXT when dealing with binary data. We also want to avoid
odd cases where SQLite will attempt to treat a number-like value
as an integer.
This should avoid problems in case non-UTF-8 URLs and pathnames are
used. They'll automatically be upgraded if not, but downgrades
to older lei would cause duplicates to appear.
|
|
Socket::MsgHdr is only packaged for Debian and derivatives at
the moment, and Inline::C pulling in gcc/clang is a huge amount
of disk space and bandwidth for some users.
This enables disk space and/or bandwidth-limited users to use lei.
Only Linux guarantees a stable ABI and syscall numbers, but
that's the majority of our userbase. FreeBSD users will still
have to use Inline::C (or get Socket::MsgHdr packaged).
x86, x32, and x86-64 are all currently supported, more to be added.

Ignoring a signal is different than blocking a signal, and the
"IgnoreSIGPIPE" option of systemd ignores.

This enables Xapian::DB_DANGEROUS to support in-place updates.
This can speed up the initial index and reduce I/O at the cost
of preventing concurrent readers and being unsafe in the face of
any abnormal terminations. This is more dangerous than
--no-fsync. --no-fsync is only unsafe in the event of a power
loss or kernel crash; --dangerous is unsafe even on SIGKILL.

Tests run under systemd (and similar) have SIGPIPE blocked by
default. This was causing this SIGPIPE test to get stuck when
run by automated builders used by Nix. Thanks to Julien
Moutinho and Dominique Martinet for tracking down this failure.

While we only store URLs and binary SHA-1/SHA-256 values in skv
at the moment, we may store potentially ambiguous keys/values in
the future. It's possible to store "02" and have it treated as
`2' unless explicitly binding parameters as SQL_BLOB. This
behavior was independent of the sqlite_unicode parameter as
evidenced by the new tests.
I only noticed this bug while hacking on another project using
DBD::SQLite, and not while hacking on public-inbox itself.
|
|
Some features didn't get used, and they're just getting in the
way of upcoming bugfixes.
|
|
Properly fixing these tests is too difficult for me at the
moment, so just disable these tests for now. A proper fix and
fleshing out support for inotify will hopefully happen at some
point.

btrfs is Linux-only at the moment (and likely to remain that way
for practical purposes). So rely on Linux ABI stability and use
the `syscall' and `ioctl' perlops rather than relying on Inline::C.
Inline::C (and gcc||clang) are monstrous dependencies which we
can't expect users to have.
This makes supporting new architectures more difficult, but new
architectures come along rarely and this reduces the burden for
the majority of Linux users on popular architectures (while
still avoiding the distribution of pre-built binaries).

Once again, our message parser class matches the more tolerant
behavior of older Email::MIME releases in order to handle
ancient messages.
This fixes <https://bugs.debian.org/1002219>, but dropping
Email::MIME entirely from the test suite may be prudent in
the future.

We can't compare created_at times with lei if lei tests are
skipped due to Inline::C or Socket::MsgHdr unavailability.

0.1s may not be enough for a task switch and inotify wakeup,
so try doubling it and see if it fixes test reliability, for
now. A future change may be to implement a watcher/tracer
for inotify -> lei/store events.

I don't expect this to be hit in real-world use via normal
interactive shells. However, somebody could accidentally add
"\n" in languages (e.g. Perl, C) where it's easy to pass "\n"
in argv[].

`"' (double-quote) needs to be quoted for stdin searches.
We also need to differentiate between "lei q --stdin" usage
when calling "lei up", do it by setting an internal "rawstr"
knob to ensure we can parse the config properly regardless
of whether the initial search used --stdin or not.
|
|
And improve reliability while we're at it. It seems closing a
TCP listen socket on FreeBSD 12.2 doesn't cause connect()-ing
clients to fail. This happens regardless of whether a socket is
IPv4 or IPv6
This non-failure was causing tests to timeout slowly on the
client side instead of failing immediately. We now fork a new
process which does nothing but accept() + shutdown() to emulate
a dead server.
Reliability improves on all OSes since there's never a point in
time when another process can bind the socket.

I noticed a description for a new inbox had st_mode=0600.

Xapian boolean terms rely on upper-case prefixes, so the terms
themselves need to be all lowercase.
|
|
SIGPIPE and SIGTERM are common and user-induced, so they're
not worth warning on. Add the value of "$?", though, since
it can help users notice other errors (e.g. SIGSEGV).
|
|
It's not much of a savings, right now, but maybe it can be in the
future. I wanted to eliminate the "lei convert" one, too, but
convert needs to preserve keywords which isn't possible with the
generic fallback, so new tests were written for convert, instead.
|
|
I just got a difficult-to-reproduce failure, here; so there's
still some issues with the up-to-dateness of the inotify watcher.
|
|
This easily allows us to treat "git diff" output as header-less
"messages" for commands such as "lei p2q".

By using the charset specified in the message, web browsers are
more likely to display the raw text properly for human readers.

The use of array-returning built-ins such as `grep' inside
arrayref declarations appears to result in permanently allocated
scratchpad space for caching according to my malloc inspector.
Thread skeletons get discarded every response, but multiple
skeletons can exist in memory at once, so do what we can to
prevent long-lived allocations from being made, here.
In other words, replacing constructs such as:
my $foo = [ grep(...) ];
with:
my @foo = grep(...);
Seems to ensure the mortality of the underlying array.

Since we want to store IMAP flags asynchronously and not wait
for results, we can't check for IMAP errors this way and end up
wasting bandwidth on public-inbox-imapd. Now, we just check
PERMANENTFLAGS up front to ensure a folder can handle IMAP flag
storage before proceeding.
|
|
We need to use a non-greedy regexp to avoid capturing the
".git" suffix in the pathname before blindly appending our
own.
|
|
Otherwise things can get noisy if bad entries exist in that
file, because they do.
|
|
Instead of:
lei forget-search $OUTPUT && rm -r $OUTPUT
we'll also allow a user to do:
rm -r $OUTPUT && lei forget-search --prune
This gives users flexibility to choose whatever flow
is most natural to them.

When the gmtime() calls were moved from feed_entry() and atom_header()
into feed_updated() in c447bbbd, @_ rather than a scalar was passed to
gmtime(). As a result, feed <updated> values end up as
"1970-01-01T00:00:00Z".
Switch back to using a scalar argument to restore the correct
timestamps.

One syscall is better than two for atomicity in Maildirs. This
means there's no window where another process can see both the
old and new file at the same time (link && unlink), nor a window
where we might inadvertantly clobber an existing file if we were
to do `stat && rename'.
|
|
I got one mysterious test failure here, once, and can't seem
to reproduce it...
|
|
While it doesn't matter to us, the Maildir spec specifies
characters are to be sorted in alphabetical order.
|
|
Maybe these will help track down some failures and make
diagnosing bugs easier. "lei export-kw" should also become
optional, even, so allow disabling it easily in the test.

Malicious clients may attempt HTTP request smuggling this way.
This doesn't affect our current code as we only look for exact
matches, but it could affect other servers behind a
to-be-implemented reverse proxy built around our -httpd.
This doesn't affect users behind varnish at all, nor the
HTTPS/HTTP reverse proxy I use (I don't know about nginx), but
could be passed through by other reverse proxies.
This change is only needed for HTTP::Parser::XS which most users
probably use. Users of the pure Perl parser (via
PLACK_HTTP_PARSER_PP=1) already hit 400 errors in this case,
so this makes the common XS case consistent with the pure Perl
case.

For odd messages with reused Message-IDs, the second message
showing up in a mirror (via git-fetch + -index) should never
clobber an entry with a different blob in over.
This is noticeable only if the messages arrive in-between
indexing runs.

Running tests over a non-interactive ssh session fails,

There's no savings in having two ways to add watches to an
inotify nor kqueue descriptor.

If lei up and edit-search work on something, so should forget-search.

When importing several sources in parallel via http(s) mboxrd,
we need to be able to get keywords of uncommitted documents
directly from shard workers. Otherwise, Xapian DocNotFound
errors happen because the read-only LeiSearch won't see
documents from uncomitted transactions. Keep in mind that it's
possible the keywords can be changed on-the-fly even for
uncommitted documents because of inotify watches from LeiNoteEvent.

Inbox->xdb does not exist, but this code path was apparently
never tested :x I noticed this on basic v2 inbox, but it could
happen with any v1/v2 inbox. Move ->num2docid into Search
so it's less awkward to use.

This test wasn't finished when I initially wrote it :x
