DBslayer segfaults on Ubuntu 9.10 AMD64,

[Chris Dew]

I've managed to configure and build beta12 of DBslayer with no issues.

When I run DBslayer, it returns immediately.

Looking at /var/log/messages I see:

Mar 11 14:18:30 chris-desktop kernel: [ 5533.107721] dbslayer[14945]:
segfault at 7f9923b8dea8 ip 00007f9922e0f675 sp 00007f9923b8deb0 error
6 in libmysqlclient_r.so.16.0.0[7f9922db6000+1c6000]

Is there a solution to this?

I've tried the -e switch, but nothing is written into the error log.

Regards,

Chris.

From the error message it looks like there is an issue w/ the libmysqlclient client lib. 

Can you give us the build flags and the libs it is currently linked against (ldd dbslayer should dump the informaiton).

Thanks for your very quick response.  The problem's gone away.

I opened a new shell, downloaded the tarball again, did the configure/make/makeinstall process again in a clean directory and the problem went away.

I'm assuming pebcak, probably some environment variables were funny from other work I'd done.

I look forward to trying out dbslayer with nodejs later this afternoon.

Thanks,

Chris.

Just wanted to say that I've got DBSlayer up and working with NodeJS.  I needed to do a minor bugfix to the javascript code http://github.com/shoeman22/node.dbslayer.js to get it to work with multi-packet result sets.  I'm now getting DBSlayer performance which looks quite usable (tens of thousands of records per second across complicated LAN from single SATA db).

Thanks,

Chris.

Awesome to hear that it is working well.
