Setting the finalizer prevents user from calling Close(),
as it would randomly result in SIGSEGV or some other silent memory corruption.
No finalizer is set for the database and user is expected to call Close() to
avoid memory leaks.
CC sets a version to int_max in ClientDBInfo indicating a refresh, however,
proxy server would reject this version for the error of future_version.
This change fixes this issue by not sending int_max, instead maintaining a
lastKnown in memory and send it to grvproxy to get latest globalconfig.
this change also fixes some java tests that were used to test the fix
This a marginal improvement which follows the C API documentation:
> It is not necessary to commit a read-only transaction – you can simply call fdb_transaction_destroy().
Read-only transactions will be always destroyed before returning to caller,
without relying on Go garbage collection; the read-only transactions
can be destroyed so early because futures created within them must never be used
outside of them.
The CTest item
* update_bindings_go_src_fdb_generated_go
will compare the generated go api with hardcoded go api to test the
generation. New FDB option will cause hardcoded go code outdated.
This change attempts to address the SIGSEGV happening when network routine is started
multiple times concurrently.
It changes the network mutex to be a RW mutex, to optimize the case
of calls when network is already started.
