Win32::API v0.48 adds cdecl function call support

In my (really little) spare time, I enjoy hacking on fun projects.
Lately, I have been struggling to get Win32::API Perl module to work on Vista with various MSVC++ and GCC compilers.

Since many have asked for it, and some brave soul had an old patch available on the net, I decided to give it a shot. I had already tried 2 or 3 times to get this patch (originally for v0.41) integrated in the new Win32::API versions, but always failed at it.

Today I decided to take the full journey, and seems I succeeded. Probably I broke something else… :-)
Please bare with me. Anyway, I have 2 things left in this release that I want to address in the new one:

– There's a Borland C macro def that is completely broken (thanks to BrowserUk for noticing)
– I need to complete the stack cleanup assembler code at the end of Call() function in the XS code. This should be easy, for some definition of "easy", since I already have some examples of MSVC/GCC assembler code in my RT queue.

Stay tuned for further updates…

MySQL is just crazy or what?

Ok, I was working on the staging/test database, checking out some performance problems I was experiencing.
Then I thought of optimizing one table. Optimizing should be like rebuilding the physical data file to compact record structures, remove invalidated data, …

MySQL has this OPTIMIZE TABLE command.
Ok, fire!

2/3 minutes passed. Then other 2/3. Then again.

I started to worry and tried to start new sessions, to see if table was blocked. It was.
Completely locked up.

Ok, I left the session running. Went to lunch. Came back.
Still running. WTF? I decided to interrupt the command. CTRL + C.

MySQL responded with some error code, 22 or something.
Ok, just check if I have to rebuild indexes, just in case.

SELECT * FROM sometable


Table corrupted. No kidding. Tried to REPAIR TABLE and REPAIR TABLE QUICK.
No way. Table was completely DESTROYED.
