I am Christian Massey a computer science student at York University
and I wish to work on Providing import and export functions for
popular data formats like JSON, XML , PHP, ... for Connector/C and
MariaDB Server. I have been inspecting the code to understand how the
dynamic column packed string is encoded and I see kind on big endian
encoding( Correct me if I am wrong please).
Also I see that the old format already work like arrays and it uses 3
bits for encoding type which is the main reason why not all types in
the enum are supported in this old format.
DBUG_ASSERT(((type - 1) & (~7)) == 0); /* fit in 3 bits */
(Again please correct me if I am wrong. The encoding is not easy to
You are right.
My Question is do we need to create a completely new type to support
arrays or do we change the old format which already work like arrays
in a way but lacks support for some types(I don't know which of the
How it is done internally not so important. But "externally" it should
be new type because:
1) we should read old types
2) we can't use old "as is" because it lack types
But "internally" code can be of course reused.
Please, I wish to write a proposal for this project and hope to
discuss more with mentors for more clarification on how we are going
to implement this as it seems to be a very important if not the most
critical part of this project.
