Chaining together `wait*` functions can create race conditions in the
frontend tests. To avoid race condition, we need to insert `then`
function between two `wait*` functions.
Because of some recent changes to the tokenizer, we no longer
need to call is_special_html_tag() to filter out special tags.
I also tried to make the start/end logic for pushing/popping
the stack more obvious.
This code is not directly related to the template parser, so it
can safely live in its own file.
The only significant change to the code is to the signature of
`html_branches` so that it can be called without requiring a file.
Since it's only used in html_grep, that has been updated to reflect
this change.
Fixes: #1774.
This hasn't been used since before Zulip was open source, and isn't
super reusable, so we can remove it. It'll always be there in the
history if someone ends up wanting it.
While we're at it, we remove the GitPython dependency (only used for
this tool) and the example MSMTP config for the review tool.
While one often might want to put the user's name in an email
template, `name` here was the user's full name, not their first name,
and thus reads as quite formal.
Our implementation of duplication detection in the Zulip email error
reporting system was buggy in two important ways:
* It did not look at the traceback, and thus considered all errors as
the same.
* It reset the 10-minute duplicate timer every time an error happened,
thus concealing situations where the same error was occuring more
often than 1/10 minutes.
I don't think the black/white fallback code is actually used by
default, and thus when it is used, it's usually a sign that something
is broken. We should throw an error, but at the very least it makes
sense to print a warning.
In d583710f7c, I apparently broke the
color emoji handling, which was masked (for test purposes) by the fact
that we catch an expection if color doesn't work and in that case fall
back to black and white emoji.
