We now triage message content for possible mentions before
going to the cache/DB to get name info. This will create an
extra data hop for messages with mentions, but it will save
a fairly expensive cache lookup for most messages. (This will
be especially helpful for large realms.)
[Note that we need a subsequent commit to actually make the speedup
happen here, since avatars also cause us to look up all users in
the realm.]
Given typeahed and the fact that this only worked if the person had a
full name that didn't contain whitespace, this side effect of the
original @shortname mentionfeature that we removed was experienced by
users as a bug.
Fixes#6142.
Process the unicode emojis in twitter link previews and render them
properly. Before this we were not processing the unicode emojis in
twitter link previews and hence on the systems which don't have
fonts for displaying them they were rendered as blank boxes.
Fixes: #5427.
This commit renames list named `to_linkify` in twitter link processor
to `to_process` and adds a `type` field to each entry in it to
indicate the type of data represented by that particular entry.
Unicode emojis when rendered should display canonical short name.
Similarly, the alt text should be of the format `:<short_name>:`.
For both of these we currently display the actual unicode symbol.
As some systems don't have the fonts necessary for displaying them
properly, they are rendered as empty square blocks. This commit also
ensures that the markup generated for emoji generated by canonical
name and by an unicode emoji is same.
Fixes: #5555.
We used shortnames for mentioning users before we had autocomplete
feature. Since we now have autocomplete typeahead, this syntax is
no more useful and just causes problems. This commit removes the
shortname mention syntax.
Fixes: #4189.
A deactivated realm emoji should neither be accepted further as a
reaction nor its further occurences in a message be rendered as an
emoji. However, all the old occurences should continue to render
normally.
The `data-toggle` property prevented the new style of overlay modals
from launching, and regardless, isn't a future-proof options for how
this should work.
The regex we were using didn't cover all the unicode blocks
to which our emojis belong. This commit fixes the regex to
include all the unicode blocks and also updates the
corresponding JS regex in marked.js.
Fixes: #3460.
Unicode codepoints are of minimum length 4, padded with extra
zeroes if the length is less than 4. This commit fixes the
`unicode_emoji_to_codepoint()` to ensure that the codepoint
it generates are of correct length.
- Add file_name field to `RealmEmoji` model and migration.

- Change emoji form for image uploading.
- Fix back-end tests.
- Fix front-end tests.
- Add tests for emoji uploading.
Fixes#1134
Earlier, a stack was being used to go through the message and search
for links. Because of this, in some cases the images were added to
the preview in reverse. Using a queue will keep the image previews in
the same order as they appeared in the message.
Fixes#4453.
By default, Python markdown tab length for indents is 4 spaces, which
require using 4 spaces or a tab to create nested elements. This
modifies that setting to specify 2-space indentation for nesting
elements only.
Modified significantly by tabbott to limit the change to just list
indentation.
Fixes#4252.
Use `name_to_codepoint.json` file (and the similar structure in
emoji_codes.js) to map emoji names directly to codepoints and change
the rendered emoji image to `unicode/<codepoint.png>` rather than
`<emoji_name>.png`.
Fixes: #3539.
We do not use `get_link_embed_data` for messsages sent by
bots, as bots often repeat the same URL over and over again
and are generally either text-focused or have their own
mechanisms to provide preview content.
Fixes#2968.
(The commit q7ef4e40258280e202325c9295579c93fb948b replaced
data-user-email with data-user-id, but we still need to
support data-user-email for old clients like non-updated
androids and we still want to start the migration forward
to data-user-id.)
This changes bugdown to use the realm passed in by the caller (if any)
for rendering, fixing a problem where bots such as the notification
bot would have their messages rendering using the admin realm's
settings, not the settings of the realm their messages are being sent
into.
Also adds a test for the notification bot case.
Fixes#3215.
A lot of care has been taken to ensure we're using the realm that the
message is being sent into, not the realm of the sender, to correctly
handle the logic for cross-realm bot users such as the notifications
bot.
This should substantially improve the clarity of the code, since
inside bugdown, this is only being used as a hash key that happens to
usually be a realm ID, not used as a Realm ID.
This change adds support for displaying inline open graph previews for
links posted into Zulip.
It is designed to interact correctly with message editing.
This adds the new settings.INLINE_URL_EMBED_PREVIEW setting to control
whether this feature is enabled.
By default, this setting is currently disabled, so that we can burn it
in for a bit before it impacts users more broadly.
Eventually, we may want to make this manageable via a (set of?)
per-realm settings. E.g. I can imagine a realm wanting to be able to
enable/disable it for certain URLs.
Now that we have updated python-markdown, we remove the deprecated
safe_mode. We used safe_mode to escape raw html, so now instead we
pass in an EscapeHtml markdown extension to the markdown engine.
See https://pythonhosted.org/Markdown/release-2.6.html for details on
the deprecation.
Fixes: #2037 (also addresses the remaining piece of #2043).
This distinguishes between YouTube Videos and Image Previews by adding
a particular “youtube-video” class to the preview along with changing
the title to the video ID rather than the link. This serves to allow
the lightbox to ID when a lightbox preview should be treated like a
YouTube video rather than an image preview.
This also modifies the tests in bug down to expect a youtube-video class
along with the title to just be the video ID on YouTube rather than the
entire URL link.
The changes that required us to fork this extension had been merged
into upstream CodeHilite, so we can remove it and switch to using the
version that comes with python-markdown.
This updates Bugdown to reflect the changes in the updated
markdown. In particular, we now pass a default config object in the
__init__ for the Bugdown extension, update the make_md_engine function
to take kwargs as opposed to a config list, and have UListProcessor
inherit from ulist as opposed to olist (which no longer works).
We update the (forked from upstream) fenced_code extension's
makeExtension to take args and kwargs, and update
FencedBlockPreprocessor __init__ method with updated Codehilite
arguments.
We update the (forked from upstream) Codehilite extension to
mirror the logic with the latest upstream Codehilite:
Add parse_hl_lines function
update makeExtension to take args and kwarfs instead of config
list
Add regex for highlight lines
use linenums instead of linenos
use get_formatter_by_name instead of HtmlFormatter
user get_lexer_by_name instead of TextLexer
add hl_lines and use_pygments arguments to the codehlite
constructor
Change the parameter name of some functions from 'md' to 'content',
since the name 'md' seems to be the reason why this parameter was
wrongly annotated.
This sets the “title” attribute on the image to the actual title of
the image specified by the user in their markdown, rather than just
the URL of the full link to it.
The bugdown parser no longer has a concept of which users need which
alert words, since it can't really do anything actionable with that info
from a rendering standpoint.
Instead, our calling code passes in a set of search words to the parser.
The parser returns the list of words it finds in the message.
Then the model method builds up the list of user ids that should be
flagged as having alert words in the message.
This refactoring is a little more involved than I'd like, but there are
still some circular dependency issues with rendering code, so I need to
pass in the rather complicated realm_alert_words data structure all the way
from the action through the model to the renderer.
This change shouldn't change the overall behavior of the system, except
that it does remove some duplicate regex checks that were occurring when
multiple users may have had the same alert word.
We now raise an exception in bugdown.do_convert() if rendering
fails, to avoid silent failures, and then calling code can convert
the exception to a JsonableError.
!avatar, !modal_link, !gravatar, etc. were incorrectly being processed
before the escape character for code blocks.
While we're at it, we add tests for these special syntaxes.
Many stubs in xml.etree.ElementTree use Union[str, bytes] as
return type. Mypy wants us to correctly handle each case. This
is correct, but not useful for us since we know that we'll always
get str. So force the return value to text_type, to supress mypy
errors.
Add a class 'BaseHandler' and make it a base class of OuterHandler,
QuoteHandler and CodeHandler. This will help annotate some functions
and improve type checking.
Change `str` to `text_type` in annotations in zerver/models.py
related to realm emoji and realm filters.
Also fix clashing annotations in zerver/lib/bugdown/__init__.py.
Had to add some "type: ignore" because the pattern used in match
doesn't affect the type returned. A fix for this issue has been pushed
to typeshed - https://github.com/python/typeshed/pull/244
Since we don't have a stable way to get the Dropbox preview failure
image (and it was sorta a weird setup anyway), it seems best to just
remove the condition.
This also requires updating the required version of oauthlib; previously an
appropriate version was being installed only because it was a dependency of
the wrong twitter library.
This only affects development environments and/or hand-built
installations relying on the contents of requirements.txt.
To fix existing environments, the incorrect api needs to be explicitly
removed with `pip uninstall twitter`.
Fixes#86.
This reverts commit 39f2908a32c0276b1d87ecedc876c71dd35a9b2f.

These images at least load now, but that's because Camo redirects
the browser to the origin server, so the only effect is an extra
round-trip time.
(imported from commit 0d6b9c888a5cdfaa9299272d74a085e872dfa434)
Now we can nest fenced code/quote blocks inside of quote
blocks down to arbitrary depths. Code blocks are always leafs.
Fenced blocks start with at least three tildes or backticks,
and the clump of punctuation then becomes the terminator for
the block. If the user ends their message without terminators,
all blocks are automatically closed.
When inside a quote block, you can start another fenced block
with any header that doesn't match the end-string of the outer
block. (If you don't want to specify a language, then you
can change the number of backticks/tildes to avoid amiguity.)
Most of the heavy lifting happens in FencedBlockPreprocessor.run().
The parser works by pushing handlers on to a stack and popping
them off when the ends of blocks are encountered. Parents communicate
with their children by passing in a simple Python list of strings
for the child to append to. Handlers also maintain their own
lists for their own content, and when their done() method is called,
they render their data as needed.
The handlers are objects returned by functions, and the handler
functions close on variables push, pop, and processor. The closure
style here makes the handlers pretty tightly coupled to the outer
run() method. If we wanted to move to a class-based style, the
tradeoff would be that the class instances would have to marshall
push/pop/processor etc., but we could test the components more
easily in isolation.
Dealing with blank lines is very fiddly inside of bugdown.
The new functionality here is captured in the test
BugdownTest.test_complexly_nested_quote().
