9a682fb20a started performing message fetching in a read-only
transaction. However, our use of `get_or_create_huddle` can violate
the read-only promise, and result in a user-facing 500.
In the cases where we're attempting to narrow to a huddle that does
not exist, this is equivalent to a false condition; catch those,
without making the huddle row, and insert a false.
Adds backend support for "channels" operator.
This will deprecate/replace the "streams" operator eventually, but
we will keep support of the operator for backwards compatibility
for a while.
Part of renaming stream to channel project.

Prep commit for deprecating the "stream" search operator and
replacing it with the "channel" operator, and for depreacting the
"streams" operator and replacing it with the "channels" operator.
Replaced HUDDLE attribute with DIRECT_MESSAGE_GROUP using VS Code search,

Rename the existing 'wildcard_mentioned' flag to
'stream_wildcard_mentioned'.
The 'wildcard_mentioned' flag is deprecated and exists for
backwards compatibility.
We have two separate flags for stream and topic wildcard mentions,
i.e., 'stream_wildcard_mentioned' and 'topic_wildcard_mentioned',
respectively.
* stream wildcard mentions: `@all`, `@everyone`, and `@stream`
* topic wildcard mentions: `@topic`
The `wildcard_mentioned` flag is included in the events and
API response if either `stream_wildcard_mentioned` or
`topic_wildcard_mentioned` is set.
Earlier, the 'wildcard_mentioned' flag was set for both the
stream and topic wildcard mentions.
Now, the 'topic_wildcard_mentioned' flag is set for topic
wildcard mentions, and the 'wildcard_mentioned' flag is set for
stream wildcard mentions.
We will rename the 'wildcard_mentioned' flag to
'stream_wildcard_mentioned' in a later commit.
These queries benefit from the increased specificity of using the
realm / recipient / sender indexes. The argument from 11a1cb9630
does not apply in these cases, since there are only 2 usermessage rows
for each matching message row for DMs, and few more than that for
huddles.
The unique index on `(user_id, message_id)` that is the
`zerver_usermessage` table is rather specific, and even the PostgreSQL
extended statistics are not enough for it to realize there is a
correlation between the `realm_id` in the message table and the
`user_id` in the usermessage table. This means that adding the
`realm_id` limit when there is a join to `zerver_usermessage` flips
the query plan from a nested loop of unique usermessage index-only
scan, with an index scan of the messages pkey -- to a parallel hash
join of the messages limit with a index scan of just the user_id limit
on usermessages. It thinks this is necessary because it thinks that
the `realm_id` limit may remove a large number of messages from the
usermessage set -- which is totally untrue.
Remove the `realm_id` limit if we have a usermessage join.
This commit addresses the issue where the topic highlighting
in search results was offset by one character when an
apostrophe was present. The problem stemmed from the disparity
in HTML escaping generated by the function `func.escape_html` which
is used to obtain `topic_matches` differs from the escaping performed
by the function `django.utils.html.escape` for apostrophes (').
func.escape_html | django.utils.html.escape
-----------------+--------------------------
' | '
To fix this SQL query is changed to return the HTML-escaped
topic name generated by the function `func.escape_html`.
Fixes: #25633.
Expands support for the message ID operand for id" operator to be either
a string or an integer. Previously, this operand was always validated as
a string.
Translators benefit from the extra information in the field names, and
need the reordering freedom that isn’t available with multiple
positional fields.

This is a first step toward two goals:
* support dictionary-like narrows when registering events
* use readable dataclasses internally
This is gonna be a somewhat complicated exercise due to how
events get serialized, but fortunately this interim step
doesn't require any serious shims, so it improves the codebase
even if the long-term goals may take a while to get sorted
out.
The two places where we have to use a helper to convert narrows
from tuples to dataclasses will eventually rely on their callers
to do the conversion, but I don't want to re-work the entire
codepath yet.
Note that the new NarrowTerm dataclass makes it more explicit
that the internal functions currently either don't care about
negated flags or downright don't support them. This way mypy
protects us from assuming that we can just add negated support
at the outer edges.
OTOH I do make a tiny effort here to slightly restructure
narrow_filter in a way that paves the way for negation support.
The bigger goal by far, though, is to at least support the
dictionary format.
We no longer pass in a big opaque event to narrow_filter
(which is inside build_narrow_filter). We instead explicitly
pass in message and flags. This leads to a bit more type
safety, and it's also more flexible. There's no reason to
build an entire event just to see if a message belongs to
a narrow.
The changes to the test work around the fact that the fixtures
are sloppy with types. I plan a subsequent commit to clean
up those tests significantly.
Adds backend support for `dm-including` operator. This will
deprecate the `group-pm-with` operator, but we keep support
for backwards-compatibility.
For testing updates, because the messages returned by these
two operators are different, most of the tests for `group-pm-with`
remain unchanged, but added comments about deprecated state.
Also, cleans up remaining instance of "PM" in `narrow.py` to
be "DM".
The general API changelog and documentation updates will be done
in a final commit in the series of commits that adds support for
the various new direct message narrows.
Adds backend support for `dm` operator. This will deprecate the
`pm-with` operator, but we keep support for backwards-compatibility.
For testing updates, updates the existing tests for `pm-with` to
use `dm`, and adds one basic test for `pm-with` in the `add_term`
tests as the two operators refer to the same `by_*` method.
The general API changelog and documentation updates will be done
in a final commit in the series of commits that adds support for
the various new direct message narrows.
Adds backend support for `is` operator with the `dm` operand. This
will deprecate the `is` operator with the `private` operand, but we
keep support for backwards-compatibility.
Note that there is some clean up of references to private messages
in the updated backend test. In commit 43ec7ed, the documentation
for `build_narrow_filter` wasn't updated for the rename of
`BuildNarrowFilterTest` to `NarrowLibraryTest`, so that's also
corrected in these changes.
The general API changelog and documentation updates will be done
in a final commit in the series of commits that adds support for
the various new direct message narrows.
Prior to commit a9b3a9c, the server implementation for documented
search operators with dashes, also implicitly supported clients
sending those same operators with underscores. This has been the
case sense the server side support for narrow filtering was
introduced in commit 3af2bf345a.
Updates the stricter version of mapping operator strings to `by*`
functions, to also include the underscore version of any operators
that have dashes. Adds a note that these undocumented versions are
tied to the support for the documented versions.
Updates the logic for identifying the method to use to extend the
query for the given term from a narrow to use a dictionary that
maps the operator string to the by_* method in the NarrowBuilder
class.
Previously, the by_* method was determined by building a string
based on the operator string and replacing dashes with underscores.
Ever since we started bundling the app with webpack, there’s been less
and less overlap between our ‘static’ directory (files belonging to
the frontend app) and Django’s interpretation of the ‘static’
directory (files served directly to the web).
Split the app out to its own ‘web’ directory outside of ‘static’, and
remove all the custom collectstatic --ignore rules. This makes it
much clearer what’s actually being served to the web, and what’s being
bundled by webpack. It also shrinks the release tarball by 3%.

Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.
(This does not actually upgrade our Python environment to Black 23
yet.)
