Hello Sergei,
Thank you for your clarification question.
I thought about it and came to a conclusion that having security_ctx
empty is an unusual case that lead me to thinking that MariaDB version
was the cause.
I upgraded my server version from 5.5.65 to 10.5.4 and the UDFs started
to work, security_ctx was no longer empty and I could extract a
username.
Thank you!
Best regards,
Denis

Hello guys,
I am building a set of MariaDB UDFs that require to know a name of a
user who called them in each and every call. Users should not be able
to
pretend as someone else, hence usernames as an argument cannot be
used.
I compile UDFs against MariaDB headers and I was able to obtain the
current_thd, but the security_ctx pointer inside is NULL.
Could somebody give me a hint what I am doing wrong?
Thank you for your answers!
Can you show a stack trace from where you see security_ctx being NULL
in
your UDF?
