And explicitly test for respawning in t/httpd-corner.t
There's no need to have an extra entries in the process table
for most tests we run, since that's not what we're testing.
|
|
We already load PublicInbox::Spawn for which(), so using spawn()
isn't unreasonable. And rely on "skip" to log the omitted test
if w3m is missing, which means we need to update the "&&"
escaping test to be self-referential on the same line.
File::Temp was totally unused, there; and we can use "open ...,undef"
in Perl to easily create anonymous temporary files for use with
spawn().
|
|
We already load PublicInbox::Spawn, so there's no need to
add another dependency to make life difficult for potential
contributors.
|
|
We don't need to force byte semantics for a buffer we clearly
create (via ->read) with byte semantics. Since we didn't
"use bytes" in t/httpd-corner.t, it was inadvertantly made
available by IPC::Run (which goes away, next).
|
|
One small step towards making tests easier-to-run. We can rely
on "local $ENV{GIT_DIR}" for potentially shell-unsafe path
names, and the rest of our path names are relative and don't
contain characters which require escaping.
|
|
We need to check every print to a regular file for errors,
because storage devices inevitably fail.
|
|
exit($?) is never correct, since ($? >> 8) is needed to extract
the correct exit code, as other information (e.g. such as signal)
is encoded in $? in addition to the exit code.
|
|
Instead of copy-pasting the documentation for `spamcheck'.
|
|
Another case where spaces can be in TMPDIR and cause
shell expansion with `command` to fail.
|
|
It's possible (but unlikely) a user will put spaces in TMPDIR
and cause File::Temp::tempdir() to return a temporary directory
with spaces in the filename, making it unsafe for shell
expansion.
PublicInbox::Git didn't exist when t/mda.t was written, and
I just forgot about PublicInbox::Git->qx for t/plack.t :x
|
|
curl(1) can fail and we need to invalidate the test in the
rare case it fails.
|
|
While I've never seen "git log" fail on its own, it could happen
one day and we should be prepared to abort indexing when it
happens.
Beef up tests for t/spawn.t to ensure close() behaves
on popen_rd the way we expect it to.
|
|
We don't want to define $SIG{__WARN__} in the worker to call an
existing non-default callback. Instead update ->{current_info}
the same way the V2Writable master process does.
I noticed this while reindexing with a large XAPIAN_FLUSH_THRESHOLD
and seeing the wrong epoch on my terminal from a shard because the
shard worker was spawned while reindexing a higher-numbered epoch.

Since MANIFEST is tied to files tracked by git, adding generated
files such as NEWS to that is more effort than its worth (esp.
when I'm wondering if MakeMaker is useful compared to only using
GNU make).
I also have trouble reading CamelCase, so lower-case names
are nicer and more consistent with previous releases
(which were all generated with "git archive"); but did not
include NEWS.
|
|
We'll have non-7-bit ASCII in the 1.2.0 release notes.
|
|
That's the only head-scratcher of the bunch remaining, since
that relies on ranges.
|
|
Yet another case of documenting things which should NOT be used :>
|
|
Tools intended for end users need manpages, and doubly so
to convince potential users NOT to use them :)

While testing 216light.css changes, I managed to hit some cases
where dillo failed to render ' correctly, but I also can't
reproduce it reliably. Anyways, it's definitely a problem with
some old browsers and newer versions of highlight already work
around it, but Debian 10.x has 3.41, so use "'" to maximize
compatibility.
|
|
"#ff0" foreground on a "#fff" background is just too difficult
to distinguish, among other things. So choose slightly darker
colors when using a (painful) "#fff" background.

We need to detect "git apply" failures reliably when patches
fail. This is necessary for solving for blob 81c1164ae5 in
https://public-inbox.org/git/ when at least two messages can
solve for it (and one of them fails):
1. https://public-inbox.org/git/b9fb52b8-8168-6bf0-9a72-1e6c44a281a5@oracle.com/
2. https://public-inbox.org/git/56664222-6c29-09dc-ef78-7b380b113c4a@oracle.com/

When solving for blob 81c1164ae5 in https://public-inbox.org/git/,
at least two messages get indexed with the dfpost result for
that blob (after fixing MsgIter to decode all text/* parts):
1. https://public-inbox.org/git/b9fb52b8-8168-6bf0-9a72-1e6c44a281a5@oracle.com/
2. https://public-inbox.org/git/56664222-6c29-09dc-ef78-7b380b113c4a@oracle.com/
However, only the first message contains a usable patch. So
we must adjust SolverGit to account for multiple messages
hitting the same "dfpost:" search result and attempt
"git apply" on all results, not just the first.
In the future, changes to SearchIdx.pm may rid us of invalid
search results and speed up performance (at the expense of
developer/indexing time); but we need to account for old search
indices, first.
|
|
We want to index text/x-patch and text/x-diff, at least,
since "git format-patch" can generate a patch series as
attachments using --attach.
|
|
ISO-2202-JP and other non-UTF-8 messages need to be displayed
correctly.
Fixes: 7d82a8bc04ce ('handle "multipart/mixed" messages which are not multipart')
|
|
--reindex has gotten better over the years, and having parallel
Xapian DB directories would exceed all available disk space for
some users with giant inboxes.
|
|
Spell "Schwartzian" correctly, and clarify the location of
"modified" since we have multiple subs named "modified"

Tools intended for end users need manpages.

While it's not RFC2919-conformant, mail software can
theoretically set multiple List-ID headers. Deliver to all
inboxes which match a given List-ID since that's likely the
intended.

|
Multiple List-ID headers will be supported in the next commit
|
|
And use it for mda, since "0" could be a usable directory
if somebody insists on using relative paths...
|
|
We don't want to waste cycles parsing the message for MIME bits
if it's spam.
|
|
It makes it easier to document the default -mda behavior is
stricter than normal, including "public-inbox-learn ham"
|
|
We don't need it in the filter, here, since we have
one in the MDA package.
|
|
It's now possible to inject false-positive ham into an inbox
the same way -mda does via List-ID.
|
|
We'll be reusing it for List-ID processing in the next commit.
|
|
Users may be zeroes or blanks.
|
|
Use <foo|bar> since that seems to be the favored notation
for required command args (taking a hint from git(1) manpage).
While we're at it, remove the space after '<' for the redirect
to match git.git coding style.
|
|
It's assumed that "spam" can end up anywhere due to Bcc:, so we
need to scan every single inbox. However, "rm" is usually more
targeted and and "ham" obviously only belongs in some inboxes.
|
|
It's possible to specify these headers multiple times, and
PublicInbox::MDA->precheck takes that into account, so
-learn should, too.
|

* origin/multi-mid:
view: show X-Alt-Message-ID in permalink view, too
index: allow search/lookups on X-Alt-Message-ID
linkify: support adding "(raw)" link for Message-IDs
view: improve warning for multiple Message-IDs
view: move '<' and '>' outside <a>
view: display redundant headers in permalink
search: support multiple From/To/Cc/Subject headers
|
|
Bad things happen when user data can control our stack size.
|
|
Since we index X-Alt-Message-ID (because we need to placate some
NNTP clients), we now display it as well, since that Message-ID
could be the X-Alt-Message-ID that the reader is actually
interested in.
|
|
Since we replace extra Message-ID headers with X-Alt-Message-ID
to placate NNTP clients, we should allow searching and indexing
on X-Alt-Message-ID just like we do with Message-ID.
|
|
And use it for the per-message permalink display.
|
|
"refer" is not the correct term, here; since that would mean
multiple messages have the current message in the "References:"
header, and that's a normal occurence.
Instead, we need to warn the reader that the given message
itself has multiple Message-IDs.
|
|
Browsers may underline '<' and '>' in links, which may be
confused with '≤' and '≥'. So have the Message-ID header
display follow what we do with In-Reply-To headers and move the
"<" and ">" outside of <a> in the HTML.
|
|
Mail headers can contain multiple headers of any type, so ensure
we don't hide any information we're getting in the per-message
permalink views.
This means it's possible to have multiple From, Date, To, Cc,
Subject, and In-Reply-To headers displayed.
The thread indices are a special case, I guess, since we run
out of space on the line if the headers too long and tools like
mutt only show the first one.
|
|
We can easily support searching on messages with
multiple From/To/Cc/Subject headers just like we
do with multiple Message-ID headers.
This matches the normal mutt pager display behavior.
