◆ _dt_dev_modules_reload_defaults()

static void _dt_dev_modules_reload_defaults ( dt_develop_t * dev )

inlinestatic

Reset every module to its (already-computed) default params before history is overlaid.

reload_defaults() is NOT called here: per-image defaults are computed once, at history init (dt_dev_init_default_history) and at module instance creation. Re-running it on every pop was the source of subtle bugs – it touched GUI state on half-built widgets, and it re-derived cross-module defaults (e.g. channelmixerrgb's WB-derived illuminant) against a proxy that the pipeline had populated, so a fresh history no longer matched a manual reset. Here we only apply the existing default_params (cheap, no recompute), so modules absent from history fall back to their defaults; modules present in history are overwritten by _history_to_module() right after.

Parameters

dev	Develop context.

dt_dev_history_item_t * dt_dev_history_cow_touch	(	struct dt_develop_t *	dev,

Copy-on-write gate for mutating a history item in place.

If hist is exclusively owned by dev->history (refcount <= 1), returns it unchanged – safe to mutate directly. If it's shared with an outstanding snapshot (a slow reader like a pipe resync or the background DB-write job), clones it, splices the clone into dev->history in place of the original (and re-points any pipe's last_history_item that referenced it), releases the original reference, and returns the clone. Callers must mutate the returned pointer, never the one passed in.

◆ dt_dev_history_item_create()

dt_dev_history_item_t * dt_dev_history_item_create ( void )

Allocate a fresh, blank history item with refcount 1.

The only correct way to create a new (not duplicated-from-an-existing-one) history item – centralizes the calloc + refcount init so no caller pokes dt_dev_history_item_t::refcount directly. Returns NULL on allocation failure.

	)

Out-of-history transient param channel.

Lets a focused module (drawlayer realtime stroke, ashift/crop edit mode) push a thread-safe snapshot of its in-progress parameters to the pipeline for rendering, WITHOUT writing permanent history. module->params belongs to the GUI thread and must never be read from the pipeline; instead the module copies its transient params into this dev-owned slot under a mutex. The pipeline reads them (also under the mutex) and commits them through the normal commit_params() path, so the transient state reaches the cache through the usual piece->global_hash mechanism. Only one module — the focused gui_module — is active at a time. History is touched only at the real commit, so undo/redo is not polluted and the database is not written per frame.

Publish (copy) module's transient params for the pipeline.

GUI/worker thread only. Replaces any previously published slot. blend_params may be NULL to keep using the history blend params. Does NOT trigger a recompute: the caller flags the pipe the way that fits its case — a realtime module raises DT_DEV_PIPE_TOP_CHANGED on the main pipe for a fast focused-piece resync, while a geometry-changing edit (crop/ashift) calls dt_dev_pixelpipe_resync_history_all() so every pipe replans ROI/formats.
