This endpoint will allow us to add/delete emoji reactions whose emoji
got renamed during various emoji infra changes. This was also a
required change for realm emoji migration.
This commit was tweaked significantly by tabbott for greater clarity
(with no changes to the actual logic).
When the RabbitMQ server disappears, we log errors like these:
```
Traceback (most recent call last):
File "./zerver/lib/queue.py", line 114, in json_publish
self.publish(queue_name, ujson.dumps(body))
File "./zerver/lib/queue.py", line 108, in publish
self.ensure_queue(queue_name, do_publish)
File "./zerver/lib/queue.py", line 88, in ensure_queue
if not self.connection.is_open:
AttributeError: 'NoneType' object has no attribute 'is_open'
During handling of the above exception, another exception occurred:
[... traceback of connection failure inside the retried self.publish()]
```
That's a type error -- a programming error, not an exceptional
condition from outside the program. Fix the programming error.
Also move the retry out of the `except:` block, so that if it also
fails we don't get the exceptions stacked on each other. This is a
new feature of Python 3 which is sometimes indispensable for
debugging, and which surfaced this nit in the logs (on Python 2 we'd
never see the AttributeError part), but in some cases it can cause a
lot of spew if care isn't taken.
This commit helps reduce clutter on the navigation sidebar.
Creates new directories and moves relevant files into them.
Modifies index.rst, symlinks, and image paths accordingly.
This commit also enables expandable/collapsible navigation items,
renames files in docs/development and docs/production,
modifies /tools/test-documentation so that it overrides a theme setting,
Also updates links to other docs, file paths in the codebase that point
to developer documents, and files that should be excluded from lint tests.
Note that this commit does not update direct links to
zulip.readthedocs.io in the codebase; those will be resolved in an
upcoming follow-up commit (it'll be easier to verify all the links
once this is merged and ReadTheDocs is updated).
Fixes#5265.
While fixing an issue related to email gateway messages not getting
rendered properly, I unknowingly introduced a bug in the markdown
engine updation code. This commit fixes it. The issue was that for
a realm having email gateway setup, updation of realm filters would
lead to the updation of only one of the markdown engines not both.
In remove_members_from_group_backend, we are passing user group to
remove_members_from_user_group. In remove_members_from_user_group,
expect user_group_id.
This fixes a regression in ae5ba7f4fd,
where Zulip would 500 if the newly added system bots didn't exist on
the server.
This also fixes a moderate size performance problem where we'd fetch 5
users from memcached or the database in a loop.
The intended use of $$ is for inline expressions, not for multiline
ones; ```math is an acceptable alternative for the latter. Hence,
the $$-syntax for inline TeX no longer permits newlines within it.
This was also necessary for the next change to be sensible; namely
allowing for spaces around both $$ when crafting inline TeX instead of
forcing everything to be crammed together, e.g. $$x=7$$. In order to
avoid uninentionally creating inline expressions, the opening and
closing $$'s of an inline expression must now both exactly consist of
two dollar signs, no more and no less.
Fixes: #6488.
