With INVITE_BASE_URL set, the first start failed: the template wrote the base URL in double quotes, which the config parser downloads as a remote include. With only INVITE_PAGE_PORT set, the invite page answered 503 "invite-page not configured", because the template never wrote set::invite-page.

The template now writes the base URL single-quoted and adds the set::invite-page block next to the listener: irc-host/irc-port from INVITE_IRC_HOST/INVITE_IRC_PORT (default SERVER_NAME/SSL_PORT), the network name, and INVITE_WEB_URL as the "Join via web" button when set. The conf is still rendered once, on first start.

Tested against the sha-d4167f1 image on a fresh volume: the conf validates, GET / returns the page with the ircs:// and web links, GET /i/<unknown> returns 404, and a second start leaves obbyircd.conf unchanged.

Summary by CodeRabbit

• New Features
  • Invite pages can now be configured with a destination IRC host and port, plus an optional “Join via web” link.
  • Invite URL settings reject values containing a single quote and report an error.
• Documentation
  • Updated setup guidance for invite-page settings, including exposing the page listener through a TLS reverse proxy.

Walkthrough

The Docker entrypoint validates invite URLs and generates invite-page settings from environment variables. The Docker documentation describes these settings. The SMTP module suppresses GCC deprecation warnings.

Changes: Invite configuration

Layer / File(s)	Summary
Generate and document invite settings docker/docker-entrypoint.sh, docker/obbyircd.conf.template, docker/README.md	The entrypoint rejects single quotes in the invite URLs and renders the base URL in single quotes. When the invite-page listener is enabled, it generates settings for the network name, IRC host and port, and optional web URL. The template and README describe the settings and defaults.

SMTP warning handling

Layer / File(s)	Summary
Suppress SMTP deprecation warning src/modules/smtp.c	The SMTP module adds a GCC-only diagnostic pragma to ignore deprecated-declaration warnings. SMTP behavior and the public API remain unchanged.

Full details: Title check

Explanation

The title "fix(docker): render a working invite page from the template" matches the main change. The PR changes the Docker entrypoint and config template so that the invite page renders and works on first startup. The title does not cover the smtp.c warning suppression, but that change is minor. The title uses a conventional-commit prefix, which is short and specific.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 2 files.

Review comments at @docker/docker-entrypoint.sh:
- Line 216: Update conf_has directive detection to exclude configuration
comments, including lines beginning with #, before matching directives; use the
configuration’s comment syntax so commented-out directives cannot affect
detection.
- Line 220: Update the invite configuration flow around `conf_has` to
distinguish legacy generated `base-url` and `invite-page` blocks in
`obbyircd.conf` from operator-written directives. Replace or remove only those
generated blocks based on the current `INVITE_BASE_URL` and `INVITE_PAGE_PORT`
values, removing the stale listener when the port is cleared while preserving
hand-written invite blocks.

Review comments at @docker/README.md:
- Line 74: Update the `INVITE_PAGE_PORT` documentation to explain that the
default Compose configuration does not publish this port. Include guidance to
either publish the port for a host-based reverse proxy or connect the proxy to
the Compose network.

Escape the IRC link before inserting it into HTML.

The new configuration enables this handler on fresh volumes. A request such as /c/a%22%3E%3Csvg%09onload=alert(1)%3E passes the channel checks and inserts attacker-controlled HTML into the response. A visitor opening the link can execute script on the invite-page origin. Escape ircs_link for the HTML attribute and URL-encode the channel component. (raw.githubusercontent.com)

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Align the comment with the diagnostic pragma.

#pragma GCC diagnostic ignored "-Wdeprecated-declarations" suppresses the warning, but the comment says the deprecations remain warnings. Update the comment to state that the legacy ares_gethostbyname calls are intentionally suppressed.

Proposed comment

-/* We resolve with ares_gethostbyname like src/dns.c, so we keep newer
- * c-ares deprecations as warnings. */
+/* We resolve with ares_gethostbyname like src/dns.c, so we suppress
+ * c-ares deprecation warnings for this legacy API. */
