Notably, this adds our checks on translated message strings to
`tools/test-all`, so that they don't cause surprise failures in
CI after a branch is pushed. (Alternately they could have gone
in `tools/lint` to accomplish the same goal, but `makemessages`
which they depend on is quite slow -- on my machine it takes 7s,
compared to 10s for all of `tools/lint`.)
This allows us to reliably parse the error in code, rather than
attempt to parse the error text. Because the error text gets
translated into the user's language, this error-handling path
wasn't functioning at all for users using Zulip in any of the
seven non-English languages for which we had a translation for
this string.
Together with 709c3b50f which fixed a similar issue in a
different error-handling path, this fixes#5598.
It's hinted in the registation process, and as long as one person in the
realm does it, everyone else will know. The tooltip also draws too much
visual attention.
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.
Add test to check if the embedded bot service being used is in the
registry or not.
Add test to check if the bot being added to the registry has a valid
bot corresponding to it.
Move 'get_bot_handler' to 'zerver/lib/bot_lib.py' as it is an independent
function, not related to the 'EmbeddedBotWorker' class that it was
previously a part of.
This fixes the original issue that #5598 was the root cause of; when
the user returns to a Zulip browser tab after they've been idle past
the timeout (10 min, per IDLE_EVENT_QUEUE_TIMEOUT_SECS), we now
correctly reload the page even if they're using Zulip in German or
another non-English language where we have a translation for the
relevant error message.
The one purpose this exception was serving was to carry a message
in `msg`. We can do that with `JsonableError`, and as a bonus replace
a repetition of the familiar "'result': 'error', ..." JSON pattern
with a call to a common implementation.
Also wrap the error messages for translation -- we hadn't been doing
that, oops. Our linter notices that issue now that it's the familiar
JsonableError class.
There's one other potential change in behavior here: this
except-clause might now catch a JsonableError raised from some other
code. That seems like a bonus, if so; the handler isn't doing
anything actually specific to this code, and the more exceptions it
successfully turns into proper error responses to the client and lines
in the log, the better.
All JsonableError subclasses now have corresponding ErrorCode values
of their own, reducing the number of different patterns for using
the new JsonableError API.
This provides the main infrastructure for fixing #5598. From here,
it's a matter of on the one hand upgrading exception handlers -- the
many except-blocks in the codebase that look for JsonableError -- to
look beyond the string `msg` and pass on the machine-readable full
error information to their various downstream recipients, and on the
other hand adjusting places where we raise errors to take advantage
of this mechanism to give the errors structured details.
In an ideal future, I think all exception handlers that look (or
should look) for a JsonableError would use its contents in structured
form, never mentioning `msg`; but the majority of error sites might
continue to just instantiate JsonableError with a string message. The
latter is the simplest thing to do, and probably most error types will
never have code looking for them specifically.
Because the new API refactors the `to_json_error_msg` method which was
designed for subclasses to override, update the 4 subclasses that did
so to take full advantage of the new API instead.
This simplifies things for all codepaths not involving this feature.
Using this feature becomes slightly easier when you're already
defining a subclass, but now requires you to define a subclass.
Currently we use it just once out of >100 uses of JsonableError, and
that use already has a subclass, so this seems like a win.
With #5598 there will soon be an application-level error code
optionally associated with a `JsonableError`, so rename this
field to make clear that it specifically refers to an
HTTP status code.
Also take this opportunity to eliminate most of the places
that refer to it, which only do so to repeat the default value.
The file `zerver/lib/request.py` doesn't have type annotations
of its own; if they did, they would duplicate the annotations that
exist in its stub file `zerver/lib/request.pyi`. The latter exists
so that we can provide types for the highly dynamic `REQ` and
`has_request_variables`, which are beyond the type-checker's ken
to type-check, but we should minimize the scope of code that gets
that kind of treatment and `JsonableError` is not at all the sort of
code that needs it.
So move the definition of `JsonableError` into a file that does
get type-checked.
In doing so, the type-checker points out one issue already:
`__str__` should return a `str`, but we had it returning a `Text`,
which on Python 2 is not the same thing. Indeed, because the
message we pass to the `JsonableError` constructor is generally
translated, it may well be a Unicode string stuffed full of
non-ASCII characters. This is potentially a bit of a landmine.
But (a) it can only possibly matter in Python 2 which we intend to
be off before long, and (b) AFAIK it hasn't been biting us in
practice, so we've probably reasonably well worked around it where
it could matter. Leave it as is.
The whole thing is an error, so "message" is a more apt word for the
error message specifically. We abbreviate that as `msg` in the actual
HTTP responses and in the signatures of `json_error` and friends, so
do the same here.
In order to benefit from the modern conveniences of type-checking,
add concrete, non-Any types to the interface for JsonableError.
Relatedly, there's no need at this point to duck-type things at
the places where we receive a JsonableError and try to use it.
Simplify those by using straightforward standard typing.
This fixes some error message strings and skips converting request_data
into json. From now, conversion would be the responsibility of interface.
Also, base_url is now not passed into event structure.
