From: Not Zed Date: Wed, 20 Dec 2023 08:57:15 +0000 (+1030) Subject: Implement state as multi-entry. X-Git-Url: https://code.zedzone.au/cvs?a=commitdiff_plain;h=1b3971cafa407f93b48634d065392050a477a6a1;p=playerz Implement state as multi-entry. Implement 'play now' state so it returns to the list afterwards as expected. --- diff --git a/dbindex.c b/dbindex.c index 89eeaf1..1f0745b 100644 --- a/dbindex.c +++ b/dbindex.c @@ -264,8 +264,8 @@ void dbindex_abort(MDB_txn *tx) { mdb_txn_abort(tx); } -int dbstate_get(MDB_txn *tx, dbindex *db, dbstate *s) { - MDB_val key = { .mv_data = "state", .mv_size = strlen("state") }; +int dbstate_get(MDB_txn *tx, dbindex *db, const char *id, dbstate *s) { + MDB_val key = { .mv_data = (char *)id, .mv_size = strlen(id) }; MDB_val data; db->res = mdb_get(tx, db->meta, &key, &data); @@ -275,6 +275,13 @@ int dbstate_get(MDB_txn *tx, dbindex *db, dbstate *s) { if (p->size != sizeof(dbstate)) return MDB_NOTFOUND; *s = *p; + + printf("dbstate get '%s'\n", id); + printf(" state: %08x\n", s->state); + printf(" listd: %d\n", s->listid); + printf(" seq: %d\n", s->seq); + printf(" filed: %d\n", s->fileid); + return 0; } else { printf("dbstate get: %s\n", mdb_strerror(db->res)); @@ -283,12 +290,18 @@ int dbstate_get(MDB_txn *tx, dbindex *db, dbstate *s) { return db->res; } -int dbstate_put(MDB_txn *tx, dbindex *db, dbstate *s) { - MDB_val key = { .mv_data = "state", .mv_size = strlen("state") }; +int dbstate_put(MDB_txn *tx, dbindex *db, const char *id, dbstate *s) { + MDB_val key = { .mv_data = (char *)id, .mv_size = strlen(id) }; MDB_val data = { .mv_data = s, .mv_size = sizeof(*s) }; s->size = sizeof(dbstate); + printf("dbstate put '%s'\n", id); + printf(" state: %08x\n", s->state); + printf(" listd: %d\n", s->listid); + printf(" seq: %d\n", s->seq); + printf(" filed: %d\n", s->fileid); + return mdb_put(tx, db->meta, &key, &data, 0); } diff --git a/dbindex.h b/dbindex.h index 5de544c..f74acf0 100644 --- a/dbindex.h +++ b/dbindex.h @@ -93,8 +93,8 @@ dbtxn *dbindex_begin(dbindex *db, dbtxn *txn, int readonly); int dbindex_commit(dbtxn *tx); void dbindex_abort(dbtxn *tx); -int dbstate_get(dbtxn *tx, dbindex *db, dbstate *s); -int dbstate_put(dbtxn *tx, dbindex *db, dbstate *s); +int dbstate_get(dbtxn *tx, dbindex *db, const char *id, dbstate *s); +int dbstate_put(dbtxn *tx, dbindex *db, const char *id, dbstate *s); dbdisk *dbdisk_get(dbtxn *tx, dbindex *db, int diskid); dbdisk *dbdisk_get_uuid(dbtxn *tx, dbindex *db, const char *uuid); diff --git a/http-monitor.c b/http-monitor.c index 1c47834..aa52d1a 100644 --- a/http-monitor.c +++ b/http-monitor.c @@ -162,7 +162,7 @@ static void write_file_json(struct obstack *os, dbfile *file) { static void write_state_json(dbindex *db, struct obstack *os) { dbtxn *tx = dbindex_begin(db, NULL, 1); dbstate state; - int res = dbstate_get(tx, db, &state); + int res = dbstate_get(tx, db, "state", &state); dbfile *file = NULL; printf("state.fileid = %d\n", state.fileid); diff --git a/music-player.c b/music-player.c index d4429ec..11917a6 100644 --- a/music-player.c +++ b/music-player.c @@ -622,7 +622,7 @@ int audio_checkpoint_state(struct audio_player *ap) { printf("checkpoint state=%d file=%d pos=%zd poss=%f '%s'\n", ap->playing_state.state, ap->playing_state.fileid, ap->playing_state.pos, ap->playing_state.poss, ap->playing ?
