This adds `--automated` and `--no-automated` flags to all Zulip
management commands, whose default is based on if STDIN is a TTY.
This enables cron jobs and supervisor commands to continue to report
to Sentry, and manually-run commands (when reporting to Sentry does
not provide value, since the user can see them) to not.
Note that this only applies to Zulip commands -- core Django
commands (e.g. `./manage.py`) do not grow support for `--automated`
and will always report exceptions to Sentry.
`manage.py` subcommands in the `upgrade` and `restart-server` paths
are marked as `--automated`, since those may be run semi-unattended,
and they are useful to log to Sentry.
This commit adds a post upgrade hook to run the
'send_zulip_update_announcements' management command.
The aim is to improve UX for self hosters by sending
zulip updates as soon as the upgrade completes instead
of waiting for the cron to run.
Zulip already has integrations for server-side Sentry integration;
however, it has historically used the Zulip-specific `blueslip`
library for monitoring browser-side errors. However, the latter sends
errors to email, as well optionally to an internal `#errors` stream.
While this is sufficient for low volumes of users, and useful in that
it does not rely on outside services, at higher volumes it is very
difficult to do any analysis or filtering of the errors. Client-side
errors are exceptionally noisy, with many false positives due to
browser extensions or similar, so determining real real errors from a
stream of un-grouped emails or messages in a stream is quite
difficult.
Add a client-side Javascript sentry integration. To provide useful
backtraces, this requires extending the pre-deploy hooks to upload the
source-maps to Sentry. Additional keys are added to the non-public
API of `page_params` to control the DSN, realm identifier, and sample
rates.
