Re: [Liberty-eiffel] Database access with Liberty

[Cyril ADRIAN]

Hi,

I don't remember the status of EDC. I'll start with unearthing it, then we can look at what is right or wrong. AFAIR the API needs some love.

Cheers,

Hello there,

I need database access with my LibertyEiffel application. What do you
generally think about this topic? We have ESE/EDC - which I never used,
but I somehow like it. @Cyril you once wrote that you have some concerns
about the implementation. What exactly are they? I'd like to see
database support in Liberty in some way and EDC is already available, so
why not just continue it? For Mysql it would need a working GDA wrapper,
@Paolo: you merged the EWLC wrappers into the Liberty repo once, but
removed them again with commit 96b0345c13246bd3e6b6a5a685dd1407b65868a.
Was this intentional? What do you think would be necessary to get GDA
working?

I currently see the options:

1. lowlevel wrapper of mysql C API in my app
2. as 1 but commited wrapper to Liberty
3. lowlevel wrapper for mysql C API as EDC backend
4. generated GDA wrapper (requires GLib and GObject, right?) use
directly in the app
5. as 4 but with EDC on top

What do you think is the best in terms of effort to get it working and
to keep it working after updates of dependent libs? Which way should I
choose?

BTW: do we have some documentation about generating wrappers? Or do I
have to look into the Makefiles to see how gccxml and wrappers-generator
are to be used to generate a wrapper`
