By default, Django sets up two handlers on this logger, one of them
its AdminEmailHandler. We have our own handler for sending email on
error, and we want to stick to that -- we like the format somewhat
better, and crucially we've given it some rate-limiting through
ZulipLimiter.
Since we cleaned out our logging config in e0a5e6fad, though, we've
been sending error emails through both paths. The config we'd had
before that for `django` was redundant with the config on the root --
but having *a* config there was essential for causing
`logging.config.dictConfig`, when Django passes it our LOGGING dict,
to clear out that logger's previous config. So, give it an empty
config.
Django by default configures two loggers: `django` and
`django.server`. We have our own settings for `django.server`
anyway, so this is the only one we need to add.
The stdlib `logging` and `logging.config` docs aren't 100% clear, and
while the source of `logging` is admirably straightforward the source
of `logging.config` is a little twisty, so it's not easy to become
totally confident that this has the right effect just by reading.
Fortunately we can put some of that source-diving to work in writing
a test for it.
We had been waiting on doing this for a long time to make sure the
feature actually did what it was supposed to (completed last week);
this change adds the typeahead to ensure it actually works.
While we're fixing this, we remove the split between the edit and
compose code paths for typeahead, which is good, because we'd already
accidentally added the syntax-highlighting feature in only one place.
Fixes#195.
Nobody has used this feature in years, and it causes certain types of
markdown issues in development to completely DoS the development
environment by making it possible for the "Bugdown timeout" exception
handler to timeout in bugdown.
Since we already send an email to the server administrators, there's
no need to replace this feature with anything.
This function is designed to replace avatar_url() and
avatar_url_from_dict() over time.
There are a few things new about it:
* We make the parameters more explicit, rather than
passing in an opaque dictionary or requiring a
UserProfile object. (A lot of our callers want
to use `values()` for efficiency sake, since we
are often doing bulk user operations.)
* We start to support the client_gravatar option.
We never make an actionable distinction between the "unknown"
presence status and the "offline" status, so we now
just use "offline" as the status for persons who don't
have recent presence records that the client knows about.
(Usually, users without presence rows have never been online,
or they have been deactivated, or they have been offline so long
that they don't show up in our date-limited queries.)
We are about to stop supporting the presence status of "unknown."
Part of this fix is to stop checking for that status.
The implication of this change is that when we go
to display the time a user was last online, we now
mostly just look to see if presence.last_active_date
is undefined. We were wary of that approach before, but it
is probably the most sane approach here.
I updated the comment abover this section to reflect
our philosophy going forward.
BTW the timestamp is kind of buried in the UI for now, as you have to
open the popover and then hover over the circular presence
indicator.
This commit adds a test to check if the user forgot to run
`tools/update-locked-requirements` after updating dependencies.
Modified by tabbott to disable it by default, since it takes over a
minute to run.
Fixes: #6324.
While it might be useful to have created welcome-bot earlier in a
certain sense, it's definitely not a good idea in this populate_db
implementation, because doing so threw off the random initial
assignment of users to streams and thus broke the casper tests.
Unfortunately, GitHub's web UI for generating release tarballs uses
`.gitattributes` to control what files to download, and thus if you
downloaded a source tarball for older Zulip versions using the GitHub
web UI, you'd be missing important files.
We fix this for future releases by moving the blacklist out of
.gitattributes.
Fixes#129.
This works around a bug in Django in handling the error case of a
client sending an inappropriate HTTP `Host:` header. Various
internal Django machinery expects to be able to casually call
`request.get_host()`, which will attempt to parse that header, so an
exception will be raised. The exception-handling machinery attempts
to catch that exception and just turn it into a 400 response... but
in a certain case, that machinery itself ends up trying to call
`request.get_host()`, and we end up with an uncaught exception that
causes a 500 response, a chain of tracebacks in the logs, and an email
to the server admins. See example below.
That `request.get_host` call comes in the midst of some CSRF-related
middleware, which doesn't even serve any function unless you have a
form in your 400 response page that you want CSRF protection for.
We use the default 400 response page, which is a 26-byte static
HTML error message. So, just send that with no further ado.

We sometimes get blueslip errors from browsers that are clearly still
attempting to reload long after they should have. These browsers can
produce a lot of unnecessary presence update exceptions.
To solve that, we start checking reload_in_progress in the presence
code path.
While we're at it, we also add some blueslip logging for the reload
code path, in case it becomes useful when debugging future issues.
We've had a few reports of users using modern Chrome having problems
where reload.is_in_progress() was true, but the browser was just
sitting there, not having reloaded.
This will continually attempt to reload the page periodically try and
compensate for the behavior in Chrome where it appears that the tab
has to be active or semi-active for `location.reload` to be respected
when Chrome is trying to save power, which means that it should just
continually try until the page is active again, in which case the
`location.reload` func will work and reload the page.
See https://developers.google.com/web/updates/2017/03/background_tabs
for the Chrome featureset that we believe may be involved with this
issue.
Tweaked by tabbott to reload earlier and add the on-focus handler.
Fixes: #6821.
While applying formatting to drafts if any draft contains some syntax
which our markdown processor is unable to process delete the draft so
that drafts overlay can be opened without any error. Also report the
exception to the server so that error can be fixed.
