This commit increases the rendered_content limit from 2x to 10x of the
original message length.
Earlier, we had placed a limit of MAX_MESSAGE_LENGTH * 2 for the
rendered content (explained in commit
77addc5456). That limit was based on
the assumption that in most cases, the rendered content wouldn't cause
a large increase in message length. However, quite prominently in
syntax highlighted codeblocks, that wasn't true and this caused the
limit condition to be hit for long messages composed primarily of code
blocks.
Example: The following message would render close to 10x it's original size.
```py
if:
def:
print("x", var)
x = y
```
Because the syntax highlighted logic is extremely compressible, having
rendered_content reach up to 100KB doesn't create a network
performance problem.
Usually, to debug a small change, you have to remove some tests from JSON
because of lack of support for comments in JSON. This commit allows to
ignore some tests by setting `"ignore" : true` in the bugdown fixtures.
Also, since this is only for while developing, the complete test suite will
throw an error if we leave an 'ignored' test in a commit.
Also switches the default behaviour of the code to not translate the
emoticons. Earlier, the code was testing-aware, and used to translate
when there was no user profile data available(assuming that as a testing
environment).
In 18e43895ff we replaced
stream subscribe buttons with stream links. The new feature
has been well tested and well received for over a year now,
so it's safe to remove the older feature at this point.
Older sites will have super old messages that still have the
rendered markup; this commit does not attempt to address those
situations. Most likely, clicking on an old button in the old
message will either do nothing or look like a message reply.
This commit migrates realm emoji to be addressed by their `id` rather
than their name. This fixes a long standing issue which was causing
an error on uploading an emoji with same name as a deactivated realm
emoji.
Fixes: #6977.
This field has been unused by clients for some time, and isn't great
for our public archive feature plans (where we'll not want to be
including email addresses in messages).
Add `translate_emoticons` to `prop_types` and `expected_keys`.
Furthermore, create a emoji-translating Markdown inline pattern.
Also use a JavaScript version of `translate_emoticons` and then use
this function during Markdown previews and as a preprocessor. This
is only needed for previews, because usually emoticon translation
happens on the backend after sending.
Add tests for emoticon translation, a settings UI, and a /help/ page
as well.
Tweaked by tabbott to fix various test failurse as well as how this
handles whitespace, requiring emoticons to not have adjacent
characters.
Fixes#1768.
This commit prefixes stream names in urls with stream ids,
so that the urls don't break when we rename streams.
strean name: foo bar.com%
before: #narrow/stream/foo.20bar.2Ecom.25
after: #narrow/stream/20-foo-bar.2Ecom.25
For new realms, everything is simple under the new scheme, since
we just parse out the stream id every time to figure out where
to narrow.
For old realms, any old URLs will still work under the new scheme,
assuming the stream hasn't been renamed (and of course old urls
wouldn't have survived stream renaming in the first place). The one
exception is the hopefully rare case of a stream name starting with
something like "99-" and colliding with another stream whose id is 99.
The way that we enocde the stream name portion of the URL is kind
of unimportant now, since we really only look at the stream id, but
we still want a safe encoding of the name that is mostly human
readable, so we now convert spaces to dashes in the stream name. Also,
we try to ensure more code on both sides (frontend and backend) calls
common functions to do the encoding.
Fixes#4713
This enforces `**` around all the mentions including "at-all" and
"at-everyone" mentions. Hence this makes `@all` and `@everyone`
invalid mentions, resulting into proper syntax for these mentions as
`@**all**` and `@**everyone**` respectively.
Note from tabbott: This removes an old feature/syntax, which made
sense back when @Tim was also a way to mention a user with Tim as
their first name. Given how nice typeahead is now, the user part of
the feature was removed a while ago; this should have gone at the same
time.
Fixes: #8143.
If some bug in Bugdown results in a rendered message content that is
bigger than twice the message size, we now just throw an exception
from Bugdown. This is considerably better than the old behavior,
which might result in an enormous message being placed in the database
(potentially, bigger than the 1MB limit to store in memcached), which
would in turn result in tragic consequences.
This fixes#8322, in that it prevents the super bad outcome seen there
(where basically Zulip became unusable for everyone on the stream
where the message is posted). Now, the failure mode is just the
message failing to send. Still not ideal (and requires further work
on the URL embed feature), but not a minor problem, not a major one.
Adds a check for newline that was present on backend, but missing in the
frontend markdown implementation. Updating messages uses is_me_message flag
received from server instead of its own partial test. Similarly, rendering
previews uses markdown code.
Fixes#6493.
This also amends a commit from Brock Whittaker <brock@zulipchat.com>
that merges two separate functions for YouTube videos and Vimeo videos
into a generic video recall function.
Fixes#7550.
Hides URL if the message content == image url so that sending gifs or
images feels less cluttered. Uses the url_to_a() function to generate
the expected url string for matching.
Fixes#7324.
Appends "Test: " text to some tests to make changes to the image preview
rendering. In the future, if the message is only a link to an image,
the link will be hidden.
Generally emails are not written with markdown in mind and hence
sometimes render in strange ways. This commit fixes a particular
issue that was causing whitespace before paragraphs to be treated
as code block due to which email content was being rendered in a
box that scrolls in right direction a lot.
Fixes: #7045.
This adds the data model and bugdown support for the new UserGroup
mention feature.
Before it'll be fully operational, we'll still need:
* A backend API for making these.
* A UI for interacting with that API.
* Typeahead on the frontend.
* CSS to make them look pretty and see who's in them.
This commit switches to use sprite sheets for rendering emojis
in all the remaining places, i.e., message bodies and composebox
typeahead. This commit also includes some changes to notifications.py
file so that the spans used for rendering emojis can be converted
to corresponding image tags so that we don't break the emoji rendering
in missed message emails since we can't use sprite sheets there.
As part of switching the bugdown system to use sprite sheets, we need
to switch the name_to_codepoint mappings to match the new sprite
sheets. This has the side effect of fixing a bunch of emoji like
numbers and flag emoji in the emoji pickers.
Fixes: #3895.
Fixes: #3972.
