}

Variants§

§

Error

An error condition and the reader was not killed.

§

ProceedWithoutKillingReader

The callback was unable to solve the problem and agreed on MDBX_MAP_FULL error; MDBX should increase the database size or return MDBX_MAP_FULL error.

§

Success

The callback solved the problem or just waited for a while, libmdbx should rescan the reader lock table and retry. This also includes a situation when corresponding transaction terminated in normal way by mdbx_txn_abort() or mdbx_txn_reset(), and may be restarted. I.e. reader slot isn’t needed to be cleaned from transaction.

§

ClearReaderSlot

Transaction aborted asynchronous and reader slot should be cleared immediately, i.e. read transaction will not continue but mdbx_txn_abort() nor mdbx_txn_reset() will be called later.

§

ReaderProcessTerminated

The reader process was terminated or killed, and MDBX should entirely reset reader registration.
