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
`example_regex` parameter. It can now be used to extract code examples
from javascript_examples.py.
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
lifetime token.

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).
Fixes#13913.

Right now, the message is "Invalid characters in emoji name" when
the emoji_name is empty. Changing check_valid_emoji_name() in
zerver/lib/emoji.py which validates the name to accomodate the case
of missing name. The new message is "Emoji name is missing".
