| Summary | 0003059: Implementation of a persistent per peer storage | ||||
| Description | Multiple components need to store per-peer information and retrieve these information after gnunet restart. To provide this functionality in a central manner, an idea is to modify the peerinfo service, storing only hello information, to a "peerstore" service to persistently store per-peer information in a key-value mapping. Clients will to store a value under a key (e.g. the subsystem name) and pass a pointer to the data and size information and peerstore will store this data in a backend. Peerstore will be agnostic of the data. Peerstore will provide functions to store and retrieve this data. We suggest the usage of an api backend to provide the possibility to use a database engine in addition to file base storage. | ||||
| Steps To Reproduce | To move from peerinfo to peerstore, we have to modify current functionality focused on storing HELLO messages and provide a way to retrieve the HELLO messages | ||||
| Tags | No tags attached. | ||||
| Required functions are: struct GNUNET_PEERSTORE_Handle * GNUNET_PEERSTORE_connect (const struct GNUNET_CONFIGURATION_Handle *cfg); void GNUNET_PEERSTORE_disconnect (struct GNUNET_PEERSTORE_Handle *h); /* Iterate */ struct GNUNET_PEERSTORE_IteratorContext * GNUNET_PEERSTORE_iterate (struct GNUNET_PEERSTORE_Handle *h, const struct GNUNET_PeerIdentity *peer, /* can be NULL */ struct GNUNET_TIME_Relative timeout, GNUNET_PEERSTORE_Processor callback, void *callback_cls); GNUNET_PEERSTORE_iterate_cancel (struct GNUNET_PEERSTORE_IteratorContext *ic); /* Watch */ struct GNUNET_PEERSTORE_NotifyContext * GNUNET_PEERSTORE_notify (const struct GNUNET_CONFIGURATION_Handle *cfg, const struct GNUNET_PeerIdentity *peer, /* can be NULL */ const char *key, /* can be NULL */ GNUNET_PEERSTORE_Processor callback, void *callback_cls); void GNUNET_PEERSTORE_notify_cancel (struct GNUNET_PEERSTORE_NotifyContext *nc); /* Store */ struct GNUNET_PEERSTORE_AddContext * GNUNET_PEERSTORE_store (struct GNUNET_PEERSTORE_Handle *h, const struct GNUNET_PeerIdentity *peer, const char *key, const void *value, size_t size, GNUNET_PEERSTORE_AddContinuation cont, void *add_cont_cls); void GNUNET_PEERSTORE_store_cancel (struct GNUNET_PEERSTORE_Handle *h, struct GNUNET_PEERSTORE_AddContext *ac); /* Get */ struct GNUNET_PEERSTORE_GetContext * GNUNET_PEERSTORE_get (struct GNUNET_PEERSTORE_Handle *h, const struct GNUNET_PeerIdentity *peer, const char *key, GNUNET_PEERSTORE_GetContinuation cont, void *get_cont_cls); void GNUNET_PEERSTORE_get_cancel (struct GNUNET_PEERSTORE_Handle *h, struct GNUNET_PEERSTORE_GetContext *gc); | |
| More required? | |
| Christian's comment: Clients will store value under a PeerIdentity and a subsystem name, so the key is both "char * + PublicKey", not just the subsystem name. So the 'const char *subsystem/key' argument needs to be passed to the 'GNUNET_PEERSTORE_iterate' call as well. Also, you never defined the GetContinuation/AddContinuation/Processor callbacks. | |
