Function Documentation

dt_telemetry_capture()

void dt_telemetry_capture	(	const char *	event,
		JsonObject *	properties
	)

Queue one analytics event for asynchronous delivery to PostHog.

Parameters

event	event name, e.g. "session_start".
properties	a JsonObject of event properties, or NULL. Ownership is transferred to this function (it is unref'd internally).

Non-blocking and thread-safe. No-op (and still consumes properties) when analytics is disabled or not opted in.

dt_telemetry_init()

void dt_telemetry_init

(

const gboolean

have_gui

)

Initialize opt-in usage analytics (PostHog, EU region).

This is SEPARATE from crash reporting (Sentry): it has its own consent dialog and its own preference (telemetry/enabled). On first launch with a GUI it asks the user, once, whether to share anonymous usage statistics. Analytics is started only if the user opted in and a PostHog API key was configured at build time. It sends anonymous, aggregate data (no images, file names or personal data) keyed by a random per-installation id.

Safe to call without telemetry support (USE_TELEMETRY=OFF): no-op.

Parameters

have_gui

whether a GUI is up and a consent dialog may be shown.

dt_telemetry_record_file_type()

void dt_telemetry_record_file_type	(	const struct dt_image_t *	img,
		const char *	pipeline
	)

Record the kind of an image processed during this session (extension and type flags only, never the file name or path).

De-duplicated per image+pipeline like the crash context, accumulated in-memory and sent aggregated in the "session_end" event. Thread-safe; no-op when analytics is disabled.

Parameters

img	the image being processed.
pipeline	pipeline label, e.g. "darkroom" or "export".

dt_telemetry_record_module_usage()

void dt_telemetry_record_module_usage	(	const char *	category,
		const char *	name
	)

Count one usage of a module/view/panel for the current session.

Accumulated in-memory (counts only, no order, no timing) and sent aggregated in the "session_end" event at shutdown. Thread-safe; no-op when analytics is disabled.

Parameters

category	one of "view", "lib", "iop".
name	the module's stable operation/plugin name.

dt_telemetry_shutdown()

void dt_telemetry_shutdown

(

void

)

Flush pending analytics events and stop the background worker. No-op if analytics was never started.
