Anders Kaseorg df001db1a9 black: Reformat with Black 23.
Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.

(This does not actually upgrade our Python environment to Black 23
yet.)

Zixuan James Li 059d0e7be8 settings: Make SHARED_SECRET mandatory.
This implements get_mandatory_secret that ensures SHARED_SECRET is
set when we hit zerver.decorator.authenticate_notify. To avoid getting
ZulipSettingsError when setting up the secrets, we set an environment
variable DISABLE_MANDATORY_SECRET_CHECK to skip the check and default
its value to an empty string.

Alex Vandiver 54c222d3f8 settings: Support arbitrary database user and dbname.
This adds basic support for `postgresql.database_user` and
`postgresql.database_name` settings in `zulip.conf`; the defaults if
unspecified are left as `zulip`.

Anders Kaseorg 405bc8dabf requirements: Remove Thumbor.
Thumbor and tc-aws have been dragging their feet on Python 3 support
for years, and even the alphas and unofficial forks we’ve been running
don’t seem to be maintained anymore.  Depending on these projects is
no longer viable for us.

Anders Kaseorg b7b7475672 python: Use standard secrets module to generate random tokens.
There are three functional side effects:

• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.

• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.

• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.

(The base32 alphabet is A-Z 2-7.  We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

As a result of dropping support for trusty, we can remove our old
pattern of putting `if False` before importing the typing module,

harmful on newer versions.

Tim Abbott b8e7369dee mypy: Remove type: ignores not needed in Python 3. 2017-08-25 11:04:20 -07:00
Greg Price a099e698e2 py3: Switch almost all shebang lines to use `python3`.
This causes `upgrade-zulip-from-git`, as well as a no-option run of
`tools/build-release-tarball`, to produce a Zulip install running
Python 3, rather than Python 2.  In particular this means that the
virtualenv we create, in which all application code runs, is Python 3.

One shebang line, on `zulip-ec2-configure-interfaces`, explicitly
keeps Python 2, and at least one external ops script, `wal-e`, also
still runs on Python 2.  See discussion on the respective previous
commits that made those explicit.  There may also be some other
third-party scripts we use, outside of this source tree and running
outside our virtualenv, that still run on Python 2.

Now, generate_secrets.py will never overwrite existing secrets.  In

(1) It makes it much easier to preserve secrets like Oauth tokens in a
development environment (previously, provision would destroy them).
(2) It makes it possible to automatically add new secrets as part of
the upgrade process.  In particular, this is useful for the
zulip_org_id settings.
