As a security precaution, we change the contract of some signals such that a
SafeString needs to be returned if HTML should be rendered without further
escaping.
Before, the `{% signal ... %}` and `{% eventsignal ... %}` template tags
called mark_safe themselves on all strings returned from signals. That could
lead to unsafe coding practices, where untrusted values are interpolated into
HTML format strings. However, such interpolations should usually be performed
using helpers such Django's format_html, which automatically escapes inputs
and returns a SafeString.
Now, we call conditional_escape on signal results, so that any HTML not explicitly
marked as safe gets escaped.
Most plugins are not affected by this change as they return a SafeString as a
result of Template.render already.

* Add trace IDs from request to celery task
Celery tasks will log the request ID they were triggered from:
[2026-07-02 10:33:17,614: INFO/MainProcess] Task pretix.base.services.orders.cancel_order[5f3104b3-0a54-4e49-921e-c866c4dc4c6d] received
[2026-07-02 10:33:17,614: INFO/MainProcess] Task 5f3104b3-0a54-4e49-921e-c866c4dc4c6d has trace 4d389638-00ab-4c4d-bdec-d73ac322bf44
Nested celery tasks will then contain both the request ID as well as the previous tasks:
[2026-07-02 10:33:18,354: INFO/MainProcess] Task pretix.base.services.notifications.notify[d52a3a49-9c89-4f67-bdde-9f773586fc07] received

This is a follow-up for #6318, basically the same problem but in a
neighboring query.
Performance comparison for real-world event with 13k subevents:
In [15]: %time get_grouped_items(e, subevent=se, channel=e.organizer.sales_channels.get(identifier="web"))
CPU times: user 49.1 ms, sys: 3.79 ms, total: 52.9 ms
Wall time: 1.12 s
Out[15]: ([<Item: xxx>], True
In [16]: %time get_grouped_items_patched(e, subevent=se, channel=e.organizer.sales_channels.get(identifier="web"))
CPU times: user 30.2 ms, sys: 445 μs, total: 30.6 ms
Wall time: 45.3 ms
Out[16]: ([<Item: xxx>], True)
During our [2026-06-27 incident](https://pretix.eu/about/en/blog/20260630-pretix-hosted-outage/),
we noticed that pretix is using redis at import time. This means that
gunicorn and celery process were unable to start on servers who could
currently not reach redis. This is kinda mitigated through auto-restart
on systemd or docker level, but that's not really how it is supposed to
work. Celery even has smart retry/reconnect logic that becomes pointless
this way.
* Improve subject lines for admin-facing emails
A few of the current subjects are ambiguous about the expected
action, and some omit context that would help in an inbox preview
(which event, which address). The rewrites bring them closer to
common conventions in modern transactional email (verb-led,
recipient-addressed, with recipient-meaningful variables). Two
themes:
- Action-required emails lead with the action verb. "Reset your
password", "Confirm event cancellation and bulk refund", and
"Confirm <address> as a sender address" tell the recipient up
front what's expected, where "Password recovery", "Bulk-refund
confirmation" and "Sender address verification" did not.
- Surface the relevant variable when the email is about something
specific. "Data shredding completed for <event>" is more useful
than the generic version when an admin manages several events.
"You've been invited to join <organizer>" names the inviting
organizer. "Confirm <address> as a sender address" names the
address.
The remaining rewrites are lighter rewordings. "New sign-in to
your account" replaces "Login from new source detected" because
"source" is jargon a non-technical recipient wouldn't recognise.
"Changes to your account" replaces "Account information changed"
because the possessive frames the email as being about the
recipient's own account.
Also fixes a hardcoded "pretix" in the confirmation-code subject.
* Standardise admin email sign-offs as "Thanks, The <instance> Team"
The current sign-offs ("Best regards, Your <instance> team") have
a formal tone. A review of the last ~20 transactional emails in
my inbox showed most senders use something friendlier:
- Thanks: Deliveroo, Starling Bank, GitHub, Cloudflare
- Thank you: AWS
- Sincerely: Google Workspace
A small minority (e.g., Sentry) had no sign-off at all. "Thanks"
was the most common, and among that group "The <instance> Team"
was the consistent phrasing rather than "Your <instance> team".
Two templates (cancel_confirm, export_failed) didn't have a
sign-off; they now get one for consistency. Notification emails
are deliberately excluded: they're system alerts rather than
direct correspondence.
* Add anti-phishing notice to admin emails containing confirmation codes
Three admin emails send the recipient a confirmation code to
enter back into a form: confirmation_code, email_setup, and
cancel_confirm. Only confirmation_code had an anti-phishing
warning, and its wording was awkward ("Please do never give this
code to another person. Our support team will never ask for this
code.").
This commit standardises the warning across all three:
> Don't share this code with anyone. The <instance> team will
> never ask you for it.
* Add structured details to login-notice email
The single-sentence body ("The login was performed using <agent>
on <os> from <country>.") is replaced with a labelled bullet list:
Time, Browser, Operating system, Device, Country.
Time and Device are new fields. Device is omitted when ua-parser
can't identify the device, Country when GeoIP isn't available,
so the user only sees fields with real values.
* Restructure notification.txt for clearer layout
- Attributes: bullet list instead of paragraph-per-attribute.
- Actions: label gets a colon, URL on its own paragraph (was
4-space-indented code block).
- Footer: separated by --- and bulleted (manage / disable
links). "Click here X" phrasing dropped (incidentally moots
a missing-"to" typo).
- Minor whitespace fix: detail-block endif now matches the
placement of the rest of the template.
notification.html's footer text is also updated, only to match
the new .txt wording (link labels and intro line). No
structural changes to the HTML template.
* Improve confirmation-code email reason strings
- Drop the redundant "to confirm" opener.
- Replace hardcoded "your pretix account" in email_verify
with "{instance}".
* Polish admin email body copy
A small wording and formatting pass on the admin email bodies,
in three loosely-grouped themes:
1. Sentence case for body text (previously lowercase after
"Hello,"), matching standard English convention.
2. Light restructuring where helpful: bullet lists for sets
of labelled facts; 4-space-indented code blocks for codes
the recipient is meant to type back.
3. Phrasing polish. Some sentences tightened or shortened.
Largely matters of taste, but generally read smoother.

* Add event placeholder support to more fields
I found it useful to be able to use the `{event}` placeholder in
some fields such as the "End of presale text" because I don't need
to fix the texts creating a new event by cloning another event.
I made placeholders available to the other fields as well (where not too
difficult). Specifically `presale_has_ended_text`, `voucher_explanation_text`
`banner_text`, `banner_text_bottom` and `event_info_text`.
In addition, I grouped them under a new `texts` variable in the `context`
(including `frontpage_text` which was part of the root `context` previously).
