We now handle the all/everyone/stream case at
the top of userMentionHandler.
Previously the code would do strange things
in the case that some user had the name "all"
or "everyone" or "stream". It would only
affect local echo, and maybe we prevent users
from having those names, so I doubt there
were any real user-facing issues here.
But the new code is clearly more simple and
more correct.
Most of this logic is specific to markdown
message processing, so we move the code to
markdown.js.
The only responsibility that we leave with
`emoji.js` is to provide us with a list
of translations (regex and replacement text).
But now `markdown.js` actually (directly) executes
those translations against Zulip messages
as part of its preprocessing.
This should simplify the upcoming mobile conversion.
Instead of mobile needing to duplicate this fairly
complex function, they will just need to pass
us in a list similar to `emoji_translations` inside
of `emoji.js`. That code has a comment that shows
what the data structure looks like.
There are six emoticon regexes that allow us
make translations such as ":)" to ":slight_smile".
We now build these as soon as we read in the
JSON data, instead of rebuilding them every time
we convert a message to markdown.
It's possible that we should just hardcode this
data:
[
{ regex: /(\:\))/g, replacement_text: ':slight_smile:' },
{ regex: /(\(\:)/g, replacement_text: ':slight_smile:' },
{ regex: /(\:\/)/g, replacement_text: '😕' },
{ regex: /(<3)/g, replacement_text: '❤️' },
{ regex: /(\:\()/g, replacement_text: ':frown:' },
{ regex: /(\:\|)/g, replacement_text: '😑' }
]
OTOH I suppose it's possible that some server
admins will want to modify emoji_codes.json to
have custom emoticons.
I am 99% sure we can rely on trimRight() and
trim() being available in all browsers that
we support. I verified in FF.
This removes the util dependency from both
modules touched here.
We now treat util like a leaf module and
use "require" to import it everywhere it's used.
An earlier version of this commit moved
util into our "shared" library, but we
decided to wait on that. Once we're ready
to do that, we should only need to do a
simple search/replace on various
require/zrequire statements plus a small
tweak to one of the custom linter checks.
It turns out we don't really need util.js
for our most immediate code-sharing goal,
which is to reuse our markdown code on
mobile. There's a little bit of cleanup
still remaining to break the dependency,
but it's minor.
The util module still calls the global
blueslip module in one place, but that
code is about to be removed in the next
few commits.
I am pretty confident that once we start
sharing things like the typeahead code
more aggressively, we'll start having
dependencies on util. The module is barely
more than 300 lines long, so we'll probably
just move the whole thing into shared
rather than break it apart. Also, we
can continue to nibble away at the
cruftier parts of the module.
This generalizes existing code for the presence code path that is
generically useful for avoiding useless work that will be discarded.
We make an exception for the one type of request that needs to happen
while reloading, namely the one to clean up our event queue.
We used to have a block of code doing this just in the presence
endpoint because that's where we'd had error-handling problems with it
not being present, but it seems more correct for it to run
unconditionally on all HTTP requests.
This requires adding a dependency of channel on reload_state, which we
record in the webpack configuration for now.
The actual goal we have is that suspect_offline is correct so that we
can rely on that field when determining how to do error handling in
the presence system.
This should return us to a situation where we won't get blueslip
browser error reporting for users created while a device was offline
just before it reloads.
This avoids risk of logging blueslip errors for user IDs seen in the
presence response that we haven't heard about from the server_events
system because we're offline and in the process of reloading.
The issue only affected large realms; see
02bc630881 and `git log
-Ssuspect_offline` for details.
