Prior to this change, there were reports of 500s in
production due to `export.extra_data` being a
Nonetype. This was reproducible using the s3
backend in development when a row was created in
the `RealmAuditLog` table, but the export failed in
the `DeferredWorker`. This left an entry lying
about that was never updated with an `extra_data`
field.
To fix this, we catch any exceptions in the
`DeferredWorker`, and then update `extra_data` to
encode the failure. We also fix the fact that we
never updated the export UI table with pending exports.
These changes also negated the use for the somewhat
hacky `clear_success_banner` logic.
This will give help up write new digest only if the db rebuild
succeeds. We were relying on the caller to
be successful in building db, this was hacky and unreliable.
We write new db digest once the caller succeeds, this ensures
that we write new digest after every successful attempt.
This fixes the anomality we were facing that Databases were rebuild
on the 2nd provision attempt with no changes to files or migrations.
This was happening because we didn't write a new digest for db
after the first provision (The case of DB didn't exist).
During the 1st provision, we check the template_status() of
Database both Dev and Test, but database_exists() of Databases
obviously returned false, and we rebuild the database,
but forgot to write_new_digest and hence the anomaly in the
second provision explained above.
This ensures that if one deletes `zproject/dev-secrets.conf`, we end
up rebuilding the databases from scratch (which, critically, will
ensure the password that gets setup matches what's in the current
version of the configuration file).
This should address a category of issue we've had where deleting
`zproject/dev-secrets.conf` would result in provision failing.
The logic in do_set_realm_property would previously "change" the email
addrssees of every user in the realm, even if they hadn't actually
changed.
We fix this by skipping the logic when it's unnecessary.
bulk_update is used to update the email of user_profile objects in
database when email_address_visibility is changed.
This helps resolve the problem of timeout errors in realms with large
number of users due to large number of database queries run in a
loop.
Since bulk_update doesn't flush caches, we need our own bit of code to
do that.
Fixes a part of #14600.
We add URLs to the `links_for_embed set`, only when
the `url_embed_preview_enabled` flag is turned on.
So, it is sufficient to check if `links_for_embed`
is not empty.
This new type eliminates a bunch of messy code that previously
involved passing around long lists of mixed positional keyword and
arguments, instead using a consistent data object for communicating
about the state of an external authentication (constructed in
backends.py).
The result is a significantly more readable interface between
zproject/backends.py and zerver/views/auth.py, though likely more
could be done.
This has the side effect of renaming fields for internally passed
structures from name->full_name, next->redirect_to; this results in
most of the test codebase changes.
Modified by tabbott to add comments and collaboratively rewrite the
initialization logic.
We now prevent these variations:
* <hr/>
* <hr />
* <br/>
* <br />
We could enforce similar consistency for other void
tags, if we wished, but these two are particularly
prevalent.
Add function in openapi.py to access endpoint descriptions written
in zulip.yaml. Use this function for creating a markdown extension
for rendering endpoint descriptions written in zulip.yaml.
We use this extension for a single endpoint to get test coverage.
The post_init cache-flushing behavior in the original alert words
migration was subtly wrong; while it may have passed tests, it didn't
have the right ordering for unlikely races.
We use post_save rather than post_init hooks precisely because they
ensure that we flush the cache after we know the database has been
updated and any future reads from the database will have the latest
state.
Previously, alert words were case-insensitive in practice, by which I
mean the Markdown logic had always been case-insensitive; but the data
model was not, so you could create "duplicate" alert words with the
same words in different cases. We fix this inconsistency by making
the database model case-insensitive.
I'd prefer to be using the Postgres `citext` extension to have
postgres take care of case-insensitive logic for us, but that requires
installing a postgres extension as root on the postgres server, which
is a pain and perhaps not worth the effort to arrange given that we
can achieve our goals with transaction when adding alert words.
We take advantage of the migrate_alert_words migration we're already
doing for all users to effect this transition.
Fixes#12563.
Previously, alert words were a JSON list of strings stored in a
TextField on user_profile. That hacky model reflected the fact that
they were an early prototype feature.
This commit migrates from that to a separate table, 'AlertWord'. The
new AlertWord has user_profile, word, id and realm(denormalization so
we can provide a nice index for fetching all the alert words in a
realm).
This transition requires moving the logic for flushing the Alert Words
caches to their own independent feature.
Note that this commit should not be cherry-picked without the
following commit, which fixes case-sensitivity issues with Alert Words.
This is a precursor commit to change the name of
AlertWordNotificationProcessor to AlertWordsNotificationProcessor
to match the change from UserProfile.alert_words to Alertword.
Previously, we added support for 'none', 'plain' and 'noop' and a
function `lang = remap_language(lang)`. This also had the potential
to encourage adding more remappings- something that we deliberatly
want to keep to a minimum.
For context, Anders K doesn't want us to keep any remapping (only
keeping 'text' which is the default no-op lexer that pygments has)
and Tim wants to keep 'plain' and 'text'. We should only document
and advertise 'text'.
Previously, the message and event APIs represented the user differently
for the same reaction data. To make this more consistent, I added a
user_id field to the reaction dict for both messages and events. I
updated the front end to use the user_id field rather than the user
dict. Lastly, I updated front end and back end tests that used user
info.
I primarily tested this by running my local Zulip build and
adding/removing reactions from messages.
Fixes#12049.
Some sites don't render correctly unless you are one of the latest browsers.
YouTube Music, for instance, changes the page title to "Your browser is
deprecated, please upgrade.", which makes our URL previews look bad.
In the original implementation, we were checking for the default language
inside format_code, which resulted in the setting being ignored when set to
quote, math, tex or latex. We shift the validation to `check_for_new_fence`
We also update the tests to use a saner naming scheme for the variables.
This commit removes can_create_streams and can_subscribe_other_users
to use has_permission as a generic function in UserProfile model for
these settings policies.
Relevant changes are made to events.py to avoid duplication at some
places.
We have two different digest schemes to make
sure we keep the database up to date. There
is the migration digest, which is NOT in the
scope of this commit, and which already
used the mechanism we use for other tools.
Here we are talking about the digest for
important files like `populate_db.py`.
Now our scheme is more consistent with how we
check file changes for other tools (as
well as the aformentioned migration files).
And we only write one hash file, instead of
seven.
And we only write the file when things have
actually changed.
And we are explicit about side effects.
Finally, we include a couple new bot settings
in the digest:
INTERNAL_BOTS
DISABLED_REALM_INTERNAL_BOTS
NOTE: This will require a one-time transition,
where we rebuild both databases (dev/test).
It takes a little over two minutes for me,
so it's not super painful.
I bump the provision version here, even
though you don't technically need it (since
the relevant tools are actually using the
digest files to determine if they need to
rebuild the database). I figure it's just
good to explicitly make this commit trigger
a provision, and the user will then see
the one-time migration of the hash files
with a little bit less of a surprise.
And I do a major bump, not a minor bump,
because when we go in the reverse direction,
the old code will have to rebuild the
database due to the legacy hash files not
being around, so, again, I just prefer it
to be explicit.
Fixes#14595.
Invalid HTTP requests could end up in an unhandled exception in
skip_200_and_304 due the record not having the status_code attribute
set. With this change we'll avoid the exception

We remove the `generate_fixtures` option here mostly
for simplicity, but in particular to facilitate
an upcoming commit to simplify the job of
`generate-fixtures` (and remove its `--force` option).
The command line option here for `test-backend`
was really calling `generate_fixtures --force`,
which we're about to rename `tools/rebuild-test-database`.
The `test-backend` tools is already smart about catching
up on migrations, so we generally don't need to tell it
to repair the database.
And if the database does get corrupt, you can just do
it directly with `tools/rebuild-test-database`.
This eliminates the `use_force` flag in
`update_test_databases_if_required`, which was easy
to confuse with `rebuild_test_database`.
The other caller wasn't using `use_force`.
Somewhat confusingly, we have two types of different
digests related to databases. The migration digests
are pragmatic, since changes to migrations are a bit
more frequent for certain use cases and don't
necessitate a complete rebuild of the database.
Anyway, these are just more specific names.

This refactors `extract_python_code_example` to accept an

Previously, the send_custom_email code path leaked files in paths that
were not `.gitignored`, under templates/zerver/emails.
This became problematic when we added automated tests for this code
path, as it meant we leaked these files every time `test-backend` ran.
Fix this by ensuring all the files we generate are in this special
subdirectory.
The purpose is to provide a way for (non-webapp) clients,
like the mobile and terminal apps, to tell whether the
server it's talking to is new enough to support a given
API feature -- in particular a way that
* is finer-grained than release numbers, so that for
features developed after e.g. 2.1.0 we can use them
immediately on servers deployed from master (like
chat.zulip.org and zulipchat.com) without waiting the
months until a 2.2 release;
* is reliable, unlike e.g. looking at the number of
commits since a release;
* doesn't lead to a growing bag of named feature flags
which the server has to go on sending forever.
Tweaked by tabbott to extend the documentation.
Closes#14618.
We now have two functions related to digests
for processes:
is_digest_obsolete
write_digest_file
In most cases we now **wait** to write the
digest file until after we've successfully
run a process with its new inputs.
In one place, for database migrations, we
continue to write the digest optimistically.
We'll want to fix this, but it requires a
little more code cleanup.
Here is the typical sequence of events:
NEVER RUN -
is_digest_obsolete returns True
quickly (we don't compute a hash)
write_digest_file does a write (duh)
AFTER NO CHANGES -
is_digest_obsolete returns False
after reading one file for old
hash and multiple files to compute
hash
most callers skip write_digest_file
(no files are changed)
AFTER SOME CHANGES -
is_digest_obsolete returns False
after doing full checks
most callers call write_digest_file
*after* running a process
I make these all functions for consistency,
and in particular I want to continue to avoid
`glob.glob` calls until we are actually
computing hashes.
This is mostly a prep to allow us to do
hashing in two separate places:
- check hashes
- update hashes
We would only update hashes **after** running
processes anew.
For `provision_inner` I considered using a
class to put the three path-related helpers
into a mini namespace, but it felt too heavy.
It wouldn't be completely implausible here
to extract something like a JSON config
file that has a list of globs for each
process that we do path-hashing for, but I
want to clean up other stuff first.
We now remove the `Type` and `_TYPE` suffixes,
as we will start treating this like a real
class with behavior, instead of a glorified
struct.
We pass in `platform_type`, so that we can
just derive some of our data from that,
where naming conventions apply.
And we use the name `migrations_status_path`,
instead of the name `migration_status`, which
had two different meanings before this change.
This is a pure refactor, and we just early-exit
in case the datbase doesn't exist (knowing that
that can be a bit of a lie now--see the comment
I added.)
Refactored code in actions.py and streams.py to move stream related
functions into streams.py and remove the dependency on actions.py.
validate_sender_can_write_to_stream function in actions.py was renamed
to access_stream_for_send_message in streams.py.
I remove `is_force` from `file_or_package_hash_updated`
and modernize its mypy annotations.
If `is_force` is `True`, we just now run the thing
we want to force-run without having to call
`file_or_package_hash_updated` to expensively
and riskily return `True`.
Another nice outcome of this change is that if
`file_or_package_hash_updated` returns `True`,
you can know that the file or package has
indeed been updated.
For the case of `build_pygments_data` we also
skip an `os.path.exists` check when `is_force`
is `True`.
We will short-circuit more logic in the next
few commits, as well as cleaning up some of
the long/wrapper lines in the `if` statements.
This is be useful for the mobile and desktop apps to hand an uploaded
file off to the system browser so that it can render PDFs (Etc.).
The S3 backend implementation is simple; for the local upload backend,
we use Django's signing feature to simulate the same sort of 60-second

For some mobile use cases, 15 seconds is potentially too short for a
busy+slow device to open a browser and fetch the URL. 60 seconds is
plenty, and doesn't carry a materially increased security risk.
When creating a webhook integration or creating a new one, it is a pain to
create or update the screenshots in the documentation. This commit adds a
tool that can trigger a sample notification for the webhook using a fixture,
that is likely already written for the tests.
Currently, the developer needs to take a screenshot manually, but this could
be automated using puppeteer or something like that.
Also, the tool does not support webhooks with basic auth, and only supports
webhooks that use json fixtures. These can be fixed in subsequent commits.
The Redis-based rate limiting approach takes a lot of time talking to
Redis with 3-4 network requests to Redis on each request. It had a
negative impact on the performance of `get_events()` since this is our
single highest-traffic endpoint.
This commit introduces an in-process rate limiting alternate for
`/json/events` endpoint. The implementation uses Leaky Bucket
algorithm and Python dictionaries instead of Redis. This drops the
rate limiting time for `get_events()` from about 3000us to less than
100us (on my system).

This adds a new realm setting: default_code_block_language.
This PR also adds a new widget to specify a language, which
behaves somewhat differently from other widgets of the same
kind; instead of exposing methods to the whole module, we
just create a single IIFE that handles all the interactions
with the DOM for the widget.
We also move the code for remapping languages to format_code
function since we want to preserve the original language to
decide if we override it using default_code_clock_language.

Semaphore has currently has two different versions of their product -
Classic and 2.0. This commit adds support for Semaphore 2.0, along side
Semaphore Classic, using the same webhook. This would let the integration
work seamlessly for users who have already configured a Zulip integration in
their Semaphore 2.0 projects.
Semaphore 2.0 currently only supports GitHub and their payloads do not
contain URLs for common entities like commits, pull requests and tags. We
construct URLs for them using templates, but also try to support other
services by providing notifications without URLs.

If we had a rule like "max 3 requests in 2 seconds", there was an
inconsistency between is_ratelimited() and get_api_calls_left().
If you had:
request #1 at time 0
request #2 and #3 at some times < 2
Next request, if exactly at time 2, would not get ratelimited, but if
get_api_calls_left was called, it would return 0. This was due to
inconsistency on the boundary - the check in is_ratelimited was
exclusive, while get_api_calls_left uses zcount, which is inclusive.
time_reset returned from api_calls_left() was a timestamp, but
mistakenly treated as delta seconds. We change the return value of
api_calls_left() to be delta seconds, to be consistent with the return
value of rate_limit().
The information used to be stored in a request._ratelimit dict, but
there's no need for that, and a list is a simpler structure, so this
allows us to simplify the plumbing somewhat.
That's the value that matters to the code that catches the exception,
and this change allows simplifying the plumbing somewhat, and gets rid
of the get_rate_limit_result_from_request function.
This commit contains a few clean ups:
* In order to scale better for adding multiple commands,
the message formatting and setting switch logic was
extracted to its own function.
* The command lists were removed, as the frontend parses
the slash command from the compose box, and only sends
a single command to the backend for any given command
alias typed.
* The `switch_command` logic was removed because, given
the aforementioned fact, the index of the command will
always be the same. Thus the switch command will always
be the same.
* Switched to using early returns as opposed to nested
conditionals. Along with removing single use variable
declarations.
This commit reuses the existing infrastructure for moving a topic
within a stream to add support for moving topics from one stream to
another.
Split from the original full-feature commit so that we can merge just
the backend, which is finished, at this time.
This is a large part of #6427.
The feature is incomplete, in that we don't have real-time update of
the frontend to handle the event, documentation, etc., but this commit
is a good mergable checkpoint that we can do further work on top of.
We also still ideally would have a test_events test for the backend,
but I'm willing to leave that for follow-up work.
This appears to have switched to tabbott as the author during commit
squashing sometime ago, but this commit is certainly:

This simplifies the update_display_settings endpoint to use REQ for
validation, rather than custom if/else statements.
The test changes just take advantage of the now more consistent
syntax.
This changes the payload that is used
to populate `page_params` for the webapp,
as well as responses to the once-every-50-seconds
presence pings.
Now our dictionary of users only has these
two fields in the value:
- activity_timestamp
- idle_timestamp
Example data:
{
6: Object { idle_timestamp: 1585746028 },
7: Object { active_timestamp: 1585745774 },
8: Object { active_timestamp: 1585745578,
idle_timestamp: 1585745400}
}
We only send the slimmer type of payload
to clients that have set `slim_presence`
to True.
Note that this commit does not change the format
of the event data, which still looks like this:
{
website: {
client: 'website',
pushable: false,
status: 'active',
timestamp: 1585745225
}
}
This commit migrates zulip outging webhook payload to
/zulip-outgoing-webhook:post in OpenAPI.
Since this migrates the last payloads from api/fixtures.json to
OpenAPI, this commit removes api/fixtures.json file and the functions
accessing the file.
Tweaked by tabbott to further remove an unnecessary conditional.
This is critical for importing the very first realm into an empty
server, since in 27b15a9722, we changed
the model to create the internal realm when the first real realm would
be created, but neglected the data import code path.
The distinction between ValueError and TypeError
is not useful in these functions:
- extract_stream_indicator
- extract_private_recipients (or its callees)
These are always invoked in views to validate
user input.
When we use REQ to wrap the validators, any
Exception gets turned into a JsonableError, so
the distinction is not important.
And if we don't use REQ to wrap the validators,
the errors aren't caught.
Now we just let these functions directly produce
the desired end result for both codepaths.
Also, we now flag the error strings for translation.
This setting is being overridden by the frontend since the last
commit, and the security model is clearer and more robust if we don't
make it appear as though the markdown processor is handling this
issue.

Zulip's modal_link markdown feature has not been used since 2017; it
was a hack used for a 2013-era tutorial feature and was never used
outside that use case.
Unfortunately, it's sloppy implementation was exposed in the markdown
processor for all users, not just the tutorial use case.
More importantly, it was buggy, in that it did not validate the link
using the standard validation approach used by our other code
interacting with links.
The right solution is simply to remove it.
When more than one outgoing webhook is configured,
the message which is send to the webhook bot passes
through finalize_payload function multiple times,
which mutated the message dict in a way that many keys
were lost from the dict obj.
This commit fixes that problem by having
`finalize_payload` return a shallow copy of the
incoming dict, instead of mutating it. We still
mutate dicts inside of `post_process_dicts`, though,
for performance reasons.
This was slightly modified by @showell to fix the
`test_both_codepaths` test that was added concurrently
to this work. (I used a slightly verbose style in the
tests to emphasize the transformation from `wide_dict`
to `narrow_dict`.)
I also removed a deepcopy call inside
`get_client_payload`, since we now no longer mutate
in `finalize_payload`.
Finally, I added some comments here and there.
For testing, I mostly protect against the root
cause of the bug happening again, by adding a line
to make sure that `sender_realm_id` does not get
wiped out from the "wide" dictionary.
A better test would exercise the actual code that
exposed the bug here by sending a message to a bot
with two or more services attached to it. I will
do that in a future commit.
Fixes#14384
The `event` parameter is never used by `process_success`,
and eliminating it allows us to greatly simplify tests
that are just confusingly passing in events that are
totally ignored.
We've had a bug for a while that if any ScheduledEmail objects get
created with the wrong email sender address, even after the sysadmin
corrects the problem, they'll still get errors because of the objects
stored with the wrong format.
We solve this by using FromAddress placeholders strings in
send_future_email function, so that ScheduledEmail objects end up
setting the final `from_address` value when mail is actually sent
using the setting in effect at that time.
Fixes#11008.
When we are fetching messages, we need to hydrate
stream names into the messages for legacy reasons.
(Ideally, we could skip this step for the webapp
and modern mobile clients, since they really only
need stream_ids, but we're not there yet.)
We keep a recipient cache that maps recipient ids
to stream names.
When we populate that cache, we now use `values(...)`
to avoid fat objects and extra DB work.
Note that we are already using a similar technique
for hydrating PM/huddle recipients.
The previous system for documenting arguments was very ugly if any of
the examples or descriptions were wrong. After thinking about this
for a while, I concluded the core problem was that a table was the
wrong design element to use for API parameters, and we'd be much
better off with individual card-type widgets instead.
This rewrites the API arguments documentation implementation to use a
basic sort of card-like system with some basic styling; I think the
result is a lot more readable, and it's a lot more clear how we would
add additional OpenAPI details (like parameter types) to the
documentation.
This commit modifies 'zerver/lib/bot_lib.py' to decouple the
user-controllable 'service_name' parameter from the value that is
passed in to 'import_module'. This is done as a precautionary
hardening.
This commit introduces two new functions in 'url_encoding.py' which
centralize two common patterns for constructing redirect URLs. It
also migrates the files using those patterns to use the new
functions.
After subscribing a stream email address to a Mailman email list
and receiving a message from it (using the polling configuration
with an Exim + Dovecot mailserver), the following error message
is emitted by Zulip:
Logger zerver.lib.email_mirror, from module zerver.lib.email_mirror line 77:
Error generated by Anonymous user (not logged in) on zulip deployment
Sender: "Foo Bar" <foo@example.com>
To: No recipient found
Missing recipient in mirror email
This is because the To: header on the received email corresponds
to the email list, and there are no other headers to indicate the
final recipient, apart from the "Envelope-To" header added by
Exim. To resolve this problem, the commit adds "Envelope-To" to
the list of headers to check for a match.
This improves the error handling for invalid values of the
propagate_mode parameter to our message editing endpoints.
Previously, invalid values would just work like change_one rather than
doing nothing.
The previous starred_messages race handling did not correctly consider
the possibility that an event queue might have been registered without
starred_messages.
Instead of operating on RateLimitedObjects, and making the classes
depend on each too strongly. This also allows getting rid of get_keys()
function from RateLimitedObject, which was a redis rate limiter
implementation detail. RateLimitedObject should only define their own
key() function and the logic forming various necessary redis keys from
them should be in RedisRateLimiterBackend.
type().__name__ is sufficient, and much readable than type(), so it's
better to use the former for keys.
We also make the classes consistent in forming the keys in the format
type(self).__name__:identifier and adjust logger.warning and statsd to
take advantage of that and simply log the key().
We don't need `do_create_user` to send a partial
event here for bots. The only caller to `do_create_user`
that actually creates bots (apart from some tests that
just need data setup) is `add_bot_backend`, which
sends the more complete event including bot "extras"
like service info.
The modified event tests show the simplification
here (2 events instead of 3).
Also, the bot tests now use tuple unpacking, which
will force a ValueError if we duplicate events
again.
We were going back to the database to get all
the users in the realm, when we had them right
there already. I believe this is a legacy
of us running on a very old version of Django
(back in early days), where `bulk_create`
didn't give you back ids in a nice way.
In the interim we added the `RealmAuditLog`
code, which does take advantage of the
existing profiles (and proves we can rely
on them).
But meanwhile we were still
doing a query to get all N users in the
realm. With `selected_related`!
To be fair, bulk_create_users() is by
its very nature a pretty infrequent
operation. This change is more motivated
by code cleanup.
Now we just loop through user_ids for
the Recipient/Subscriber foreign key rows.
I also removed some fairly convoluted code mapping
emails to user_ids and just work in user_id
space.
We try to use the correct variation of `email`
or `delivery_email`, even though in some
databases they are the same.
(To find the differences, I temporarily hacked
populate_db to use different values for email
and delivery_email, and reduced email visibility
in the zulip realm to admins only.)
In places where we want the "normal" realm
behavior of showing emails (and having `email`
be the same as `delivery_email`), we use
the new `reset_emails_in_zulip_realm` helper.
A couple random things:
- I fixed any error messages that were leaking
the wrong email
- a test that claimed to rely on the order
of emails no longer does (we sort user_ids
instead)
- we now use user_ids in some place where we used
to use emails
- for IRC mirrors I just punted and used
`reset_emails_in_zulip_realm` in most places
- for MIT-related tests, I didn't fix email
vs. delivery_email unless it was obvious
I also explicitly reset the realm to a "normal"
realm for a couple tests that I frankly just didn't
have the energy to debug. (Also, we do want some
coverage on the normal case, even though it is
"easier" for tests to pass if you mix up `email`
and `delivery_email`.)
In particular, I just reset data for the analytics
and corporate tests.
I guess `test_classes` has 100% line coverage
enforcement, which is a bit tricky for error
handling.
This fixes that, as well as making the name
snake_case and improving the format of the
errors.
This test was using the anti-pattern of doing an
assertion inside a conditional.
I added the `findOne` helper to make it easier
to write robust tests for scenarios like this.
If I send a message from a normal Zulip client, it is
considered to be "read" by me. But if I send it via
an API program (using my human account), the message
is not immediately "read" by me.
Now we handle this correctly in `get_raw_unread_data`.
The symptom of this was that these messages would get
"stuck" in "Private Messages" narrows until the next
time you reloaded your app.
Using an Exists subquery to avoid scanning the entire Subscription
table seems to speed things up greatly.
Set up with:
./manage.py populate_db --extra_users 2000 --extra-streams 1000
Tested on my computer, the original function was taking ~1.2seconds,
the optimized version only ~0.05-0.06.
Likely fixes#13874; we can re-open if after production testing we
feel more work is warranted.
In 220c2a5ff3 I
introduced a query to find invites by delivery_email
but was still using email as the key.
For most realms `email` and `delivery_email` are
synonymous, so this temporary bug would not affect
them. For realms that restrict emails, the invite
would have probably failed for other reasons, but
the symptom would have been less clear.
We now have this API...
If you really just need to log in
and not do anything with the actual
user:
self.login('hamlet')
If you're gonna use the user in the
rest of the test:
hamlet = self.example_user('hamlet')
self.login_user(hamlet)
If you are specifically testing
email/password logins (used only in 4 places):
self.login_by_email(email, password)
And for failures uses this (used twice):
self.assert_login_failure(email)
This reduces query counts in some cases, since
we no longer need to look up the user again. In
particular, it reduces some noise when we
count queries for O(N)-related tests.
The query count is usually reduced by 2 per
API call. We no longer need to look up Realm
and UserProfile. In most cases we are saving
these lookups for the whole tests, since we
usually already have the `user` objects for
other reasons. In a few places we are simply
moving where that query happens within the
test.
In some places I shorten names like `test_user`
or `user_profile` to just be `user`.
We want a clean codepath for the vast majority
of cases of using api_get/api_post, which now
uses email and which we'll soon convert to
accepting `user` as a parameter.
These apis that take two different types of
values for the same parameter make sweeps
like this kinda painful, and they're pretty
easy to avoid by extracting helpers to do
the actual common tasks. So, for example,
here I still keep a common method to
actually encode the credentials (since
the whole encode/decode business is an
annoying detail that you don't want to fix
in two places):
def encode_credentials(self, identifier: str, api_key: str) -> str:
"""
identifier: Can be an email or a remote server uuid.
"""
credentials = "%s:%s" % (identifier, api_key)
return 'Basic ' + base64.b64encode(credentials.encode('utf-8')).decode('utf-8')
But then the rest of the code has two separate
codepaths.
And for the uuid functions, we no longer have
crufty references to realm. (In fairness, realm
will also go away when we introduce users.)
For the `is_remote_server` helper, I just inlined
it, since it's now only needed in one place, and the
name didn't make total sense anyway, plus it wasn't
a super robust check. In context, it's easier
just to use a comment now to say what we're doing:
# If `role` doesn't look like an email, it might be a uuid.
if settings.ZILENCER_ENABLED and role is not None and '@' not in role:
# do stuff
