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.
In very old Slack workspaces, slackbot can appear as "Slackbot", and
the import script only checks for "slackbot" (case sensitive). This
breaks the import--it throws the assert that immediately follows the
test. I don't know how common this is, but it definitely affected our
import.
The simple fix is to compare against a lowercased-version of the
user's full name.
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 |
| 5 | 1170.0 | 546.0 | 326.0 |
| 6 | 1271.0 | 609.0 | 416.0 |
| 7 | 1125.0 | 459.0 | 299.0 |

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)
Instead of custom stubs, we now use zjquery. We also
limit a couple checks to the first call to
`show_empty_narrow_messages`, since it's the same
logic every time.
When you hover over a user that has set a user
status, we now show something like "out to lunch."
You can test this in the console by doing:
user_status.server_update({status_text: 'out to lunch'})
And then hover over your name in the buddy list.
The stubs here were kind of unnecessary, as the
real people module is lightweight and data setup
is pretty easy.
In passing I also removed the unnecessary `sed`
abbreviation.
The name `insert_user_into_list` is sort of misleading,
since we are often just redrawing the user's existing
item in the buddy list.
I chose `redraw_user` over `update_user` to emphasize
that we're just going to redraw it with whatever data
has been updated by the callers.
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.
The commit f863a9b567 had modified
jquery.filedrop's paste method to exit early if any of the items in the
clipboardData is of the string kind. The early exit was added to prevent pasting
an image thumbnail for text copied from software like MS Word, instead of
pasting the actual copied text content. When copying an image in a (modern?)
Browser, though, the clipboard seems to contain a html `img` tag item, along
with the actual image file. This resulted in pastes being broken.
This commit modifies the condition checked for the early exit. We now actually
look at the html content in the clipboard to see if it is an `img` tag, in which
case we upload the image, instead of exiting early.
Closes#7130.
This is likely not the "right" fix in that it involved a negative
margin, but this does eliminate an annoying visual glitch where the
scrollbar overflows above its container in the left sidebar, without
creating other apparent problems.
Fixes#8731.
User was able to click delete button multiple time which could cause
multiple delete requests. This commit disables and hides the delete
message button after the first click and shows a spinner until http
the delete request responds.
Also adds a casperjs test to ensure that spinner becomes visible and
delete button becomes invisible after clicking on delete button for
first time and hides spinner and show delete buttton when message is
deleted.
Fixes: #11219.
Multiple delete message requests for the same message sometimes caused
a 500 error. This happened via the normal IntegrityError being thrown
by delete message/archiving code.
This was manually reproduced by adding latency in function
move_messages_to_archive() in retention.py and
delete_message_backend() in views.py. This addresses the problem by
adding code to handle the exception and throw JsonableError to convert
500 to 400 errors, with an automated test.
This fixes a section of code that hasn't really
been turned on yet. We decided to rename
"info" to "status_text", and I apparently missed
this. We don't have any UI to set these yet,
so it was a harmless bug.
I'll try to get some better test coverage on this
when I tweak the buddy list to show user status.
Apparently, Clubhouse has two different payloads for story label
changes, one where the label name lives inside the "references"
object, and the other where it lives inside the "actions" object.
Their webhook API is still in beta, so this could just be a bug.
Anyhow, we should support both.
This commit takes away the ability for non-admin members to create
streams where only admins can post messages by hiding the option from
them.
Fixes#11290.
