Setting FDBNetworkOption::FDB_NET_OPTION_TLS_KEY_BYTES has no effect

[c4pQ]

Hi!

For some reason setting FDBNetworkOption::FDB_NET_OPTION_TLS_KEY_BYTES and similar TLS_CERT_BYTES, TLS_CA_BYTES seems like does not have any effect. We use fdb_network_set_option() for this matter.

After setting everything we receive transaction timeouts and the following in client logs:

On the other hand setting environment variables FDB_TLS_CERTIFICATE_FILE, FDB_TLS_KEY_FILE, FDB_TLS_CA_FILE with the paths to the files with same content does the trick and everything works.

We've also tried setting FDBNetworkOption::FDB_NET_OPTION_TLS_KEY_PATH and other _PATH options with no effect as well.

Environment:

• FDB 7.1.51
• Client in Docker container Linux c31802bb42bc 6.5.0-17-generic #17-Ubuntu SMP PREEMPT_DYNAMIC Thu Jan 11 14:01:59 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

The route cause is that setup was called before setting the options.

But one thing is still confusing - how we managed to apply those settings at some point and successfully access FDB while setup-set_network_option order was incorrect.
