This fixes a bug where update_message_backend would do one memcached
query per user receiving a given message. Right now we just do a
single bulk database query, but in principle we could use
generic_bulk_cached_fetch to use the cache as well.
This changes bugdown to use the realm passed in by the caller (if any)
for rendering, fixing a problem where bots such as the notification
bot would have their messages rendering using the admin realm's
settings, not the settings of the realm their messages are being sent
into.
Also adds a test for the notification bot case.
Fixes#3215.
Finishes the refactoring started in c1bbd8d. The goal of the refactoring is
to change the argument to get_realm from a Realm.domain to a
Realm.string_id. The steps were
* Add a new function, get_realm_by_string_id.
* Change all calls to get_realm to use get_realm_by_string_id instead.
* Remove get_realm.
* (This commit) Rename get_realm_by_string_id to get_realm.
Part of a larger migration to remove the Realm.domain field entirely.
This change adds support for displaying inline open graph previews for
links posted into Zulip.
It is designed to interact correctly with message editing.
This adds the new settings.INLINE_URL_EMBED_PREVIEW setting to control
whether this feature is enabled.
By default, this setting is currently disabled, so that we can burn it
in for a bit before it impacts users more broadly.
Eventually, we may want to make this manageable via a (set of?)
per-realm settings. E.g. I can imagine a realm wanting to be able to
enable/disable it for certain URLs.
Previously, the way that render_messages was calling bugdown meant
that the preview feature didn't have access to realm data like the
list of users or streams, resulting in previews for those elements
being wrong.
Now render_message_backend uses zerver.lib.render_markdown to render
messages correctly.
[Commit message tweaked and test added by tabbott]
With reactions and other upcoming features, we'll be adding several
places where we need to check whether a particular user can access a
particular message. It's best to just have a single helper function
for this purpose that we can use everywhere.
This pulls message-related code from models.py into a new
module called message.py, and it starts to break some bugdown
dependencies. All the methods here are basically related to
serializing Message objects as dictionaries for caches and
events.
extract_message_dict
stringify_message_dict
message_to_dict
message_to_dict_json
MessageDict.to_dict_uncached
MessageDict.to_dict_uncached_helper
MessageDict.build_dict_from_raw_db_row
MessageDict.build_message_dict
This fix also removes a circular dependency related
to get_avatar_url.
Also, there was kind of a latent bug in Message.need_to_render_content
where it was depending on other calls to Message to import bugdown
and set it globally in the namespace. We really need to just
eliminate the function, since it's so small and used by code that
may be doing very sketchy things, but for now I just fix it. (The
bug would possibly be exposed by moving build_message_dict out to the
library.)
I move these three functions to lib/cache.py:
to_dict_cache_key_id
to_dict_cache_key
flush_message
This will prepare us for a more significant refactoring that
eventually breaks down some circular dependencies with
Message and bugdown.
This was the original way to send messages via the Zulip API in the
very early days of Zulip, but was replaced by the REST API back in
2013.
Fixes: #730.
We no longer use all the alert words for all the users in the
entire realm when we look for alert words in a newly sent/edited
message. Now we limit the search to only all the alert words
for all the users who will get UserMessage records. This will
hopefully make a big difference for big realms where most messages
are only sent to a small subset of users.
We now use render_incoming_message() to render all incoming
new messages (sends/edits), so that they will get the same treatment.
This change also establishes do_send_messages() as the code
path to get new messages rendered. It removes some
logic from check_message() that only happened on certain code paths
for sending messages, and which would only detect failures by
expensively rendering messages, so it wasn't much of a guard.
This change also helps to phase out maybe_render_content(), which
deepens the call stack without providing much clarity to the reader,
since it's behavior is so variable.
Finally, this sets up to fix a flaw in the way we compute which
users have alert words in their messages (in a subsequent commit).
These annotations aren't perfect because the sqlalchemy stubs in
typeshed are broken (e.g. a `Select` doesn't have the ability to do
`.where()`, but we've at least used some typevars to make it easy to
address that when the sqlalchemy stubs are less broken).
This adds support for using PGroonga to back the Zulip full-text
search feature. Because built-in PostgreSQL full text search doesn't
support languages that don't put space between terms such as Japanese,
Chinese and so on. PGroonga supports all languages including Japanese
and Chinese.
Developers will need to re-provision when rebasing past this patch for
the tests to pass, since provision is what installs the PGroonga
package and extension.
PGroonga is enabled by default in development but not in production;
the hope is that after the PGroonga support is tested further, we can
enable it by default.
Fixes#615.
[docs and tests tweaked by tabbott]
Apparently, we had incorrectly concluded that our highlight_string
search result highlighting offsets coming from tsearch_extras were
measured in bytes, whereas in fact it is measured in characters.
There were a bunch of authorization and well-formedness checks in
zerver.lib.actions.do_update_message that I moved to
zerver.views.messages.update_message_backend.
Reason: by convention, functions in actions.py complete their actions;
error checking should be done outside the file when possible.
Fixes: #1150.
This is controlled through the admin tab and a new field in the Realms
table. This mirrors the behavior of the old hardcoded setting
feature_flags.disable_message_editing. Partially resolves#903.
For a long time, rest_dispatch has had this hack where we have to
create a copy of it in each views file using it, in order to directly
access the globals list in that file. This removes that hack, instead
making rest_dispatch just use Django's import_string to access the
target method to use.

This changes the type annotations for the cache keys in Zulip to be
consistently text_type, and updates the annotations for values that
are used as cache keys across the codebase.
As documented in https://github.com/zulip/zulip/issues/441, Guardian
has quite poor performance, and in fact almost 50% of the time spent
running the Zulip backend test suite on my laptop was inside Guardian.
As part of this migration, we also clean up the old API_SUPER_USERS
variable used to mark EMAIL_GATEWAY_BOT as an API super user; now that
permission is managed entirely via the database.
When rebasing past this commit, developers will need to do a
`manage.py migrate` in order to apply the migration changes before the
server will run again.
We can't yet remove Guardian from INSTALLED_APPS, requirements.txt,
etc. in this release, because otherwise the reverse migration won't
work.
Fixes#441.
We can't just check that the realms are the same because ist.mit.edu is an open
realm and uses @mit.edu email addresses.

If we call exclude_muting_conditions() with a non-stream
narrow, it will now include a condition to exclude streams
that are not in your home view. As of now, this code only
executes during testing, but it sets the stage for doing
better in:home queries on the back end.
(imported from commit bbd764bd0e9588a50e4a82c915e82a2c1b99d73e)
If we are already narrowing to a stream, then we can disregard
muted topics in all the other streams and create a simpler query
for the DB to execute.
(imported from commit 35a074a76eec99922034a381741355da3fdd5b39)
Due to the way we store muted topics, it is possible that a
muted topic stream name may no longer exist, and we need to
handle that case gracefully.

Previously, we assumed that num_before or num_after would be always be non-zero
after adjustment for the anchor. However, we don't adjust num_before or
num_after when a narrow is specified.

Behind a feature flag you can now do searches like this:
-pm-with:othello@example.com is:private
The "-" in front of "pm-with" tells us to exclude messages
with Othello from our search. We support "-" in front of
all operators, although the behavior for "-search:" and
and "-near:" doesn't really change in this commit.
Note that the filtering out of "negated" predicates only
happens on the client side in this commit. On the server
side we ignore negated predicates and send back a superset
of the results.

This commit doesn't change any functionality, and it is
designed to make diffs for upcoming changes related to
negated conditions a bit easier to read. This diff
looks a bit noiser than it really is due to some
reindentation of continuation lines.

The narrow_parameter convert now converts tuples of
(operator, operand) into dictionaries so that downstream
functions/classes deal in dictionaries. This
affects get_old_messages_backend, messages_in_narrow_backend,
and NarrowBuilder.
(imported from commit 7e8cb887f7872ec687acd8c4857d1d5222ab0d5f)
This implementation is somewhat hackish in large part because I think
we're going to be wanting to redo the get_old_messages API somewhat
soon, and this may naturally become a lot cleaner as a result, but
this isn't a lot of code and fixes#2235 part (A) and substantially
mitigates #1510.

Previously we only disabled it for 'is:starred'. This caused a backtrace when
someone searched for, say 'stream:test is:mentioned', because we weren't joining
on zerver_usermessage, which meant the flag wasn't available to filter on.

The normal code will now generate SQL that is basically identically to the raw
SQL we were using before.
(imported from commit 84a3971d6137d05ef3f71252278afdd59041e86a)
This commit also includes a few changes in the way we do some queries that
should speed searches up:
* Messages before and after the anchor are fetched in a single query by doing a
UNION ALL on the server. This incurs the cost of an extra sort because UNION
ALL does not guarantee the order that the results are appended, but it saves a
server round-trip.
* Searches involving flags now use a straight froward WHERE clause, which is
much faster than the one that django-bitfield generates (due to limitations of
the Django ORM)

This requires the tsearch_extras Postgres extension. To install the extension,
first install postgresql-9.1-tsearch-extras on both postgres-primary and
postgres-secondary (this would normally be done in a puppet apply, but there are
currently some changes that can't be applied on Postgres machines). Then run
the following as the postgres user on postgres-primary:
$ psql -d zulip -c 'CREATE EXTENSION tsearch_extras SCHEMA zulip;'
In dev environments, you must also run:
$ psql -d zulip_test_template -c 'CREATE EXTENSION tsearch_extras SCHEMA zulip;'

NarrowBuilder.by_stream and NarrowBuilder.by_topic for mit users uses a
regex to search by stream and topic. Python's re.escape escapes unicode
in a format that postgres can not parse. We escape unicode as '\uXXXX'
for postgres.
