darshanime 6078f648cb settings: use None for memcached cache timeout.
This is a cleaner approach than the old "really big number" strategy.

Maarten Rijke 841f02934d push_notifications: Add setting to redact content.
This commit adds a setting that toggles redacting content of push
notifications and replacing it with "***REDACTED***".

Rishi Gupta a08543f1ce server settings: Add setting for MAILING_ADDRESS.
The rules here are fuzzy, and it's quite possible none of Zulip's emails
need an address at all. Every country has its own rules though, which makes
it hard to tell. In general, transactional emails do not need an address,
and marketing emails do.

Tim Abbott 1ab2ca5986 subdomains: Extract zerver.lib.subdomains library.
These never really belonged with the rest of zerver.lib.utils.py, and
having a separate library makes it easier to enforce full test
coverage.

Aastha Gupta 0fae83b301 notifications: Prompt user to enable desktop notifications.
This is a two-step notifications process that will ask a user
to enable notifications and if they click exit give them three
options:

1. Enable notifications.
2. Ask later.
3. Never ask on this computer again.

The first two are self-explanatory (ask later = next session it
asks again). The third is captured and stored in localStorage and
a check is done on page load to see whether or not notifications
should be displayed.

Commit modified heavily by Brock Whittaker <brock@zulipchat.com>.

Fixes #1189.

Umair Khan 490515aea6 cleanup: Fix comment in SocialAuthMixin.auth_complete. 2017-10-13 17:13:18 -07:00
Greg Price b095463f9b logging: Clear out the Django default config on logger `django`.
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.

Greg Price 55426894cd errors: Force a super-simpler handler for 400 errors.
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.

Example exception from server logs (lightly edited):

  2017-10-08 09:51:50.835 ERR  [django.security.DisallowedHost] Invalid HTTP_HOST header: 'example.com'. You may need to add 'example.com' to ALLOWED_HOSTS.

Tim Abbott 9426ee024b logging: Filter tornado.general logging for being spammy.
Apparently, this sockjs.tornado logging code resulted in a lot of
buggy error emails whenever a Zulip browser tried to reconnect on a
new IP.  I don't see an obvious way to suppress them from within
sockjs, but that might be a good follow-up issue.

Fixes #6959.

Tim Abbott 88bb6c6cad uploads: Set a BOTO_CONFIG path to override broken GCE configuration.
The comment is pretty self-explanatory.  The fact that Google Compute

product, but hopefully this is the only really dumb thing they do.

Greg Price 0691724836 passwords: Set default zxcvbn threshold to 10k guesses.
See the discussion in the revised docs for background and motivation,
and an explanation of why this value.
2017-10-08 15:48:44 -07:00
Greg Price a116303604 passwords: Express the quality threshold as guesses required.
The original "quality score" was invented purely for populating
our password-strength progress bar, and isn't expressed in terms
that are particularly meaningful.  For configuration and the core
accept/reject logic, it's better to use units that are readily
understood.  Switch to those.

I considered using "bits of entropy", defined loosely as the log
of this number, but both the zxcvbn paper and the linked CACM
article (which I recommend!) are written in terms of the number
of guesses.  And reading (most of) those two papers made me
less happy about referring to "entropy" in our terminology.
I already knew that notion was a little fuzzy if looked at
too closely, and I gained a better appreciation of how it's
contributed to confusion in discussing password policies and
to adoption of perverse policies that favor "Password1!" over
"derived unusual ravioli raft".  So, "guesses" it is.

And although the log is handy for some analysis purposes
(certainly for a graph like those in the zxcvbn paper), it adds
a layer of abstraction, and I think makes it harder to think
clearly about attacks, especially in the online setting.  So
just use the actual number, and if someone wants to set a
gigantic value, they will have the pleasure of seeing just
how many digits are involved.

(Thanks to @YJDave for a prototype that the code changes in this
 commit are based on.)

Alena Volkova 21bc0e845c urls: Delete the json/tutorial_send_message endpoint.
This endpoint is part of the old tutorial, which we've removed, and

Vishnu Ks eef72a98e4 backends: Create custom email backend EmailLogBackEnd.
Create a new custom email backend which would automatically
logs the emails that are send in the dev environment as
well as print a friendly message in console to visit /emails
for accessing all the emails that are sent in dev environment.
Since django.core.mail.backends.console.EmailBackend is no longer
userd emails would not be printed to the console anymore.

Tim Abbott 63bbbba5aa backend: Add support for mobile_flow_otp in social auth.
It turns out that very little code change is required to support
GitHub auth on mobile.  Ideally, this would come with tests, though
the complicated part of the code path is covered by the Google auth
version.  But writing a test for this would take a long time, and I
think it's worth having the feature now, so I'll be doing tests as a
follow-up project.

Tim Abbott ef5a4000a9 settings: Clean up social auth settings.
The main change here is moving SOCIAL_AUTH_FIELDS_STORED_IN_SESSION to
be with the other hardcoded settings, since it's not something that
makes sense for a sysadmin to change.  But while we're at it, we also
group the overall social auth settings separately from the
GitHub-specific settings.

Tim Abbott 94ba678f5b email_mirror: Clean up EMAIL_GATEWAY_EXAMPLE setting.
This isn't something that a user can ever modify, so it doesn't belong
in DEFAULT_SETTINGS.  While we're at it, we align the appearance of
the email gateway in the docs with whether this setting in the docs
will be valid.
