Modules

BerkeleyBatch
| RAII class that provides access to a | Berkeley database |
BerkeleyDatabase
| An instance of this class represents | one database. | | For BerkeleyDB this is just a (env, strFile) | tuple. |
BerkeleyEnvironment
WalletDatabaseFileId

berkeley_database_sanity_check
| Perform sanity check of runtime BDB | version versus linked BDB version. |
berkeley_database_version
check_unique_fileid
| Make sure database has a unique fileid within | the environment. If it doesn’t, throw an | error. BDB caches do not work properly when | more than one open database has the same | fileid (values written to one database may | show up in reads to other databases). | | BerkeleyDB generates unique fileids by default | (https://docs.oracle.com/cd/E17275_01/html/programmer_reference/program_copy.html), | so bitcoin should never create different | databases with the same fileid, but this error | can be triggered if users manually copy | database files.
get_berkeley_env
| Get BerkeleyEnvironment given a directory | path. | | @param[in] env_directory | | Path to environment directory | | ———– | @return | | A shared pointer to the BerkeleyEnvironment | object for the wallet directory, never | empty because ~BerkeleyEnvironment | erases the weak pointer from the g_dbenvs | map. @post A new BerkeleyEnvironment | weak pointer is inserted into g_dbenvs | if the directory path key was not already | in the map. |
make_berkeley_database
| Return object giving access to Berkeley | database at specified path. |
