In the event that two processes are racing to be the
first to load data from zulip.yaml, we now make the
race scenario be duplicated effort instead of having
the second racer get an attribute error on `data`.
We do this by declaring victory only after setting
`data`. "Declaring victory" in this case is a matter
of setting `last_update`.
We are still possibly vulnerable to corrupted data
here, so we should investigate a mutex, or just
read the data on every call (but it's strangely
expensive, almost 3.5s on my instance), or converting
the YAML to code before launching the server.
We start by stripping the ids in front of the name before the database
lookup. This has the advantage of not mentioning anyone if an incorrect
user id and full name combination is specified, as well as not having
the query the database twice, once by fullname and next by id.
Previously, we were storing only the most recent person with the same
full name as others; this commit adds new keys to the dict such that
simply looking by name would get you the newest user with this name,
and the get_user_by_id function can index the remaining users.
We also remove some unreachable code. Calling
split() always returns at least one token, even
if it's just the empty string. This is tested
directly on this commit, plus messages with
empty content get rejected pretty early in
the execution path.
In user type custom field, field value is list of user ids. We weren't
converting list to json object in update event payload. This throws
error in frontend, cause we store stringify representation of custom
field value. Therefore, after update event is recieved field-value-
type gets updated to array from string which throws json parsing error.
Having HTML (or HTML-like) content in the examples was making parts of
the content invisible, since the browser identified them as HTML tags
rather than verbose text.
There are some endpoints that don't fall into the currently available
categories, so this new function will be used for calling the tests for
server and realm-related endpoints.
Using early-exit here allows us to more easily
comment why there are certain exemptions to
this logic.
We also only require callers to pass in realm,
not the whole user object.
Since this class was built, folks have always chosen
to subclass JsonableError for situations where
the default of ErrorCode.BAD_REQUEST is insufficient.
So now we simplify the use cases, which also gets
us 100% coverage on this core module.
This commit add FIELD_TYPE_CHOICES_DICT to page_params and replace
FIELD_TYPE_CHOICES.
FIELD_TYPE_CHOICES_DICT includes all field types with keyword, id
and display name. Using this field-type-dict, we can access field
type information by it's keyword, and remove all static use of
field-type'a name or id in frontend.
This commit also modifies functions in js where this page_params
field-types is used.
This commit modifies FIELD_TYPE_DATA dict in `CustomProfileField`
model to store keyword of field types. And create new dict
FIELD_TYPE_CHOICES_DICT to store all field type information
by field type keyword, i.e. id, name.
This is preparatory commit to remove all static use of field
types in frontend and access field type with keyword instead
of display name.
This prevents leaking some variables into an already
cluttered function.
We also add test coverage for what's now an
early-exit condition in the new function--we exempt
public MIT streams from these events.
This change was partially driven by a quirk in Python
where peephole optimizations make `continue` lines
appear not to be covered.
I also think it's generally a good idiom to extract
functions for loop bodies when they don't actually
accumulate values or maintain other state. With this
commit we now prevent potential bugs for vars like
`is_stream` leaking between loop iterations.
We simulate a race condition by mocking create_user
to actually create a user, but then raise an
IntegrityError (as if another process had actually
created the user, not our test).
I also changed the real code to use explicitly
named parameters.
I don't understand why this didn't cause test failures in CI; this
change was clearly required and test_change_realm_property was failing
consistently for me locally.
Our get_streams_traffic function used to query
all streams in the StreamCount table if you
passed in `None` for `streams`.
Now we require that you pass in a list of
stream_ids.
I don't know how much work this will save
the database, since probably the bulk of
the work is aggregating. If we need to fine
tune DB performance, we could possibly add
`realm` as an argument and add it to the filter.
What we'll immediately get, for large multi-realm
installations, is less data over the wire and
less work for the ORM.
The prior code uses an awkward idiom that
pre-dates the `exists()` function, and it
had an unreachable line of code.
The new version should be faster, since we
don't create a throwaway heavy Django object
or send needless data over the wire.
This functions appears to be redundant to
`access_stream_by_name`. The only
meaningful line of code in the function that we're
removing, the code that raises an error,
appears to be unreachable, despite reasonably
extensive tests.
The only thing the function was restricting
was that the case where the bot's owner was
unsubscribed to a private stream, which
is already locked down in
`access_stream_by_name` calls inside of
`patch_bot_backend`.
This commit increases test coverage
by removing unreachable code.
It's possible this function had
some theoretical value before we
introduced the `require_non_guest_human_user`
decorator to the `patch_bot_backend`
view, since in theory the bot itself
could have subscribed to a stream that
the owner didn't subscribe to. Even
then it's not clear that allowing the
bot to set that as a default stream
would have been harmful, since they
can already access it.
We want our methodology for extracting the last message
id to be consistent, particularly in terms of how we
handle edge cases. (I'll concede that the
`bulk_remove_subscriptions` codepath never hits that
corner case in practice, but it's harmless to handle
the theoretical case.)
It may also be nice to have this function show up
clearly in profiling.
This also adds some direct testing to the function.
It's not clear to me why we don't use `latest('id')`
in the implementation, but that's outside the scope
of this commit.
This de-clutters check_message a bit and also makes
it easy to audit our rules for who can write to a
stream.
Also, this works around a bug with Python where its
optimizations for the `pass` instruction make them
not appear to run and show up as uncovered in
coverage reports.
