This additional logic to prevent resizing is certain circumstances
(file size, dimensions) is necessary because the pillow gif handling
code seems to be rather flaky with regards to handling gif color
palletes, causing broken gifs after resizing. The workaround is to
only resize when absolutely necessary (e.g. because the file is larger
than 128x128 or 128KB).
Fixes#10351.
We had initially designed the poll widget like a blog
post with comments beneath it but it makes more sense
to think of it as just a simple poll with options.
We add a new syntax which converts the messages like the following:
```
/poll Who do you support?
Nadal
- Djokovic
```
to a poll with the two names as options. The list syntax is optional
since anyone making a poll is likely to want to create a list anyway.
Refactor the potentially expensive work done by Beautiful Soup into a
function that is called by the alter_content function, so that we can
cache the result. Saves a significant portion of the runtime of
loading of all of our /help/ and /api/ documentation pages (e.g. 12ms
for /api).
Fixes#11088.
Tweaked by tabbott to use the URL path as the cache key, clean up
argument structure, and use a clearer name for the function.
Earlier, our realm filters didn't render for languages that do not
use spaces (eg: Japanese) since we used to check for the presence
of an actual space character. This commit replaces that logic with
a complex scheme to detect word boundaries.
Also, we convert the RealmFilterPattern to subclass InlineProcessor
and make use of the new no-op feature in py-markdown 3.0.1 where we
can tell py-markdown that our pattern didn't find a match despite
the initial regex getting matched.
Fixes#9883.
Since we are building our parser from scratch now:
1. We have control over which proccessor goes at what priority number.
Thus, we have also shifted the deprecated `.add()` calls to use the
new `.register()` calls with explicit priorities, but maintaining
the original order that the old method generated.
2. We do not have to remove the processors added by py-markdown that
we do not use in Zulip; we explicitly add only the processors we
do require.
3. We can cluster the building of each type of parser in one place,
and in the order they need to be so that when we register them,
there is no need to sort the list. This also makes for a huge
improvement in the readability of the code, as all the components
of each type are registered in the same function.
These are significant performance improvements, because we save on
calls to `str.startswith` in `.add()`, all the resources taken to
generate the default to-be-removed processors and the time taken to
sort the list of processors.
Following are the profiling results for the changes made. Here, we
build 10 engines one after the other and note the time taken to build
each of them. 1st pass represents the state after this commit and 2nd
pass represent the state after some regex modifications in the commits
that follow by Steve Howell. All times are in microseconds.
| nth Engine | Old Time | 1st Pass | 2nd Pass |
| ---------- | -------- | -------- | -------- |
| 1 | 92117.0 | 81775.0 | 76710.0 |
| 2 | 1254.0 | 558.0 | 341.0 |
| 3 | 1170.0 | 472.0 | 305.0 |
| 4 | 1155.0 | 519.0 | 301.0 |

We avoid re-computing the regex string here, and we
also avoid re-compiling the regex itself.
I decided to put the "one_time" decorator in the
bugdown file itself, just to reduce friction in
folks reading the "buyer beware" comments.
Unfortunately, we can't use this for the
get_web_link_regex() function due to testing concerns,
so that continues to do an inelegant cache-with-global-var
scheme.
We use early-exit to flatten the code.
I also tweaked the comments a bit based on some recent
profile findings. (e.g. reading the file isn't actually
a big bottleneck, it's more the regex itself)
This fixes an annoying bug where clicking to subscribe to a stream
would change the color shown in the "manage streams" UI immediately
after you click.
Fixes#11072.
This adds a setting under "Notification" section of
"Organization settings" tab, which enables Organization administrator to
control whether the missed message emails include the message content or
not.
Fixes: #11123.
This a check on server side to verify whether the user sending request
to create stream where only admins can post is an admin or not; Raises
a JsonableError when the user is not the realm admin.
You can now pass in an info field with a value
like "out to lunch" to the /users/me/status,
and the server will include that in its outbound
events.
The semantics here are that both "away" and
"status_text" have to have defined values in order
to cause changes. You can omit the keys or
pass in None when values don't change.
The way you clear info is to pass the empty
string.
We also change page_params to have a dictionary
called "user_status" instead of a set of user
ids. This requires a few small changes on the
frontend. (We will add "status_text" support in
subsequent commits; the changes here just keep
the "away" feature working correctly.)
We now have single function that handle both away
and not-away.
This refactoring sets us up to piggyback "info" more
easily onto status updates.
The only thing that changes here is that we don't
delete database rows any more when users revoke
their away status. Instead we just set the status
to NORMAL.
`fakeldap` assumes every attribute to be a multi-value attribute
while making comparison in `_comapare_s()` and so while making
comparisons for password it gives a false positive. The result
of this was that it was possible to login in the dev environment
using LDAP using a substring of the password. For example, if the
LDAP password is `ldapuser1` even entering `u` would log you in.
On the backend, we extend the BlockQuoteProcessor's clean function that
just removes '>' from the start of each line to convert each mention to
have the silent mention syntax, before UserMentionPattern is invoked.
The frontend, however, has an edge case where if you are mentioned in
some message and you quote it while having mentioned yourself above
the quoted message, you wouldn't see the red highlight till we get the
final rendered message from the backend.
This is such a subtle glitch that it's likely not worth worrying about.
Fixes#8025.
These mentions look like regular mentions except they do not
trigger any notification for the person mentioned. These are
primarily to be used when you make a bot take an action and
the bot mentions you, or when you quote a message that mentions
you.
Fixes#11221.
Apparently, zoom's API will (sometimes?) return a 201 (not 200)
created in response to the API request to create a call. We fix this
by using the proper requests check for whether or not the request
failed.
This moves the logic for deleting the user's custom profile field
value in the remove_user_custom_profile_data view function to a method
named check_remove_user_custom_profile_value in actions.py, so that we
can reuse it in the next commit.
