◆ dt_database_close()

void dt_database_close ( void  )

Close the connection and release the lock files. Safe to call when nothing is open.

Warning
Every statement must be finalised before this returns, which is why the repositories under src/database expose a *_cleanup() each. A connection cannot be closed out from under a sqlite3_stmt still held elsewhere – and that is the reason this pair is not yet a dt_database_swap(). See src/database/README.md.

Warning
This is the escape hatch, and it is counted. Every caller of this holds a raw sqlite3 * that the module cannot account for, cannot serialise against a close, and cannot trace. tools/check_module_boundaries.sh ratchets the number of call sites downwards and it is deleted at zero – at which point the private lock below actually guarantees something and swapping workspaces at runtime becomes implementable.

Do not call it from new code: put the query in a repository under src/database and give it a name. See src/database/README.md.

void dt_database_set_prompt_handler ( dt_database_prompt_handler_t  handler)

Install the handler the module asks through. NULL removes it.

Must be registered BEFORE dt_database_open() runs – which is before dt_gui_gtk_init(), so this one cannot go where the film/collection/folder-survey handlers go. darktable.c registers it, being the only thing that knows this early whether there will be a GUI.

With no handler, every prompt answers CLOSE: a corrupt database is not deleted or restored, and a schema is not migrated, on the strength of a question nobody was asked. That is also what makes a headless run safe – these dialogs used to be built unconditionally, with no has_gui guard, on a GTK that ansel-cli never initialises.

◆ _db_lock

dt_pthread_rwlock_t _db_lock
static

Serialises the module's own work against dt_database_close().

It is a reader/writer lock rather than a mutex because that is the shape the workspace swap needs: every query takes it for reading and they proceed concurrently (sqlite is opened SERIALIZED and does its own internal locking), while closing takes it for writing and therefore waits for every in-flight query to finish.

Warning
It does NOT yet make dt_database_close() safe, and the module does not pretend otherwise. dt_database_get_sqlite3_global() hands the connection out to call sites that keep using it long after they returned, entirely outside this lock; until that count reaches zero the lock covers the module's own statements and nothing else. This is exactly why there is no dt_database_swap() yet – see src/database/README.md.

It used to live on darktable_t as database_threadsafe, reachable through common/global_mutexes.h by anything that cared to take it. Two functions in this file were its only users.
