This removes sender names from the message cache, since
they aren't guaranteed to be valid, and they're inexpensive
to add.
This commit will make the message cache entries smaller
by removing sender___full_name and sender__short_name
fields.
Then we add in the sender fields to the message payloads
by doing a query against the unique sender ids of the
messages we are processing.
This change leads to 2 extra database hops for most of
our message-related codepaths. The reason there are 2 hops
instead of 1 is that we basically re-calculate way too
much data to get a no-markdown dictionary.
Introduce MessageDict.post_process_dicts() will allow us
the ability to do the following:
* use less memory in the cache for repeated data
* prevent cache invalidation
* format data according to different client needs
The first use of this function is pretty inconsequential, but
it sets us up for more consequential changes.
In this commit we defer the MessageDict.hydrate_recipient_info
step until after we pull data out of the cache. This impacts
cache size as follows:
* streams - negligibly bigger
* PMs/huddles - slimmer due to not needing to repeat
sender data like email/full_name
Again, the main point of this change is to start setting up
the infrastructure to do post-processing.
This is a first step to eventually slimming the message cache,
but there are still some moving parts there to be worked through.
The more immediate benefit of extracting this function is that
we can put tests on it. Also, it isolates some functionality
that may go away as our clients gets smarter.
This makes the developer experience of the /emails pages significantly
cleaner, since you don't have to look at both the HTML and the text
for each message at the same time.
Fixes#6844.
This endpoint is about to become an API-style route and have the legacy
decorator removed from its view. The json/fetch_api_key endpoint will be
used in tests instead of it.
This was a not-well-thought-through behavior change done in #6489; the
part that was actually a problem was ctrl-enter not producing spaces
anyway.
So we fix this, and also add a comment explaining why.
Fixes#6908.
We now use a `.values` query to get just the fields we need
in order to fulfill '/json/users' requests.
The main benefit is that we don't do O(N) queries for bot
owners, but we also have less data on UserProfile to process.
Request for adding an reaction only if there is a default emoji or
an active realm emoji with that name while request for removing a
reaction should be sent only if there is a default emoji or a realm
emoji(may be active or deactivated) with that name. Earlier we were
not including deactivated realm emojis while deciding whether a
request for removing a reaction should be sent or not which was
causing requests for the removal of reactions with deactivated realm
emojis not to be sent to the backend.
Fixes: #6007.
On receiving a request for deleting a reaction, just check if such
a reaction exists or not. If it exists then just delete the reaction
otherwise send an error message that such a reaction doesn't exist.
It doesn't make sense to check whether an emoji name is valid or not.
This commit prepares us to introduce a StreamLite class. For
these tests, we don't care about the actual contents of the
Stream, just the right stream is there.
Since subscribed_to_stream is only doing an id lookup
on the Stream model to find out if a user is subscribed to
a stream, there's no reason to require a full Stream object.
It's currently the case that all callers do have full Stream
objects handy to pass in to this function, but it's still a
good practice to have functions only ask for objects that they
need.
It appears the mongodb repo is not accessible by Travis CI right now.
This is sadly our problem, because Travis puts a bunch of crap in
their apt `sources.list` file, so `apt-get update` starts failing.
The comment is pretty self-explanatory. The fact that Google Compute
Engine has this problem does not impress confidence about their
product, but hopefully this is the only really dumb thing they do.
Fixes#4839.
The original "quality score" was invented purely for populating
our password-strength progress bar, and isn't expressed in terms
that are particularly meaningful. For configuration and the core
accept/reject logic, it's better to use units that are readily
understood. Switch to those.
I considered using "bits of entropy", defined loosely as the log
of this number, but both the zxcvbn paper and the linked CACM
article (which I recommend!) are written in terms of the number
of guesses. And reading (most of) those two papers made me
less happy about referring to "entropy" in our terminology.
I already knew that notion was a little fuzzy if looked at
too closely, and I gained a better appreciation of how it's
contributed to confusion in discussing password policies and
to adoption of perverse policies that favor "Password1!" over
"derived unusual ravioli raft". So, "guesses" it is.
And although the log is handy for some analysis purposes
(certainly for a graph like those in the zxcvbn paper), it adds
a layer of abstraction, and I think makes it harder to think
clearly about attacks, especially in the online setting. So
just use the actual number, and if someone wants to set a
gigantic value, they will have the pleasure of seeing just
how many digits are involved.
(Thanks to @YJDave for a prototype that the code changes in this
commit are based on.)
We now return user_ids for subscribers to streams in add-stream
events. This allows us to eliminate the UserLite class for
both bulk adds and bulk removes. It also simplifies some JS
code that already wanted to use user_ids, not emails.
Fixes#6898
This function was extracted from build_user_sidebar(). We
also slightly streamlined it to not unnecessarily call
filter() when the filter text was blank. This extraction
also eliminated the need for us to have the two-line
filter_and_sort() function.
Also, we get to 100% coverage in this commit.
We now intialize user-list-filter within activity.initialize(),
which gives us more control to set the module variable
`meta.$user_list_filter` before we build the user sidebar,
while setting up its handlers after we build the sidebar.
