Adding sysinfo to the APR

[Mladen Turk <mt...@apache.org>]

Hi,

I wish to add the things we have inside tomcat-native
to the APR (with more generic API) for obtaining
various OS infos in a portable way.

Right now, inside tomcat-native we have a set of
functions that can obtain:

inf[0]  - Total usable main memory size
inf[1]  - Available memory size
inf[2]  - Total page file/swap space size
inf[3]  - Page file/swap space still available
inf[4]  - Amount of shared memory
inf[5]  - Memory used by buffers
inf[6]  - Memory Load

inf[7]  - Idle Time in microseconds
inf[8]  - Kernel Time in microseconds
inf[9]  - User Time in microseconds

inf[10] - Process creation time (apr_time_t)
inf[11] - Process Kernel Time in microseconds
inf[12] - Process User Time in microseconds

inf[13] - Current working set size.
inf[14] - Peak working set size.
inf[15] - Number of page faults.

All that is available for a multiple platforms (linux, solaris, macosx, windows).
IMHO, something like that can be very usable with a proper API to the
much wider audience.

Comments?

Regards,
Mladen.

The Win32 registry can be easily exported to the plain
text file and used from multiple platforms like any other configuration
file. So, having a registry/file API would be usable on all platforms
if someone needs that.

Thanks William for the link, and Mladen for the thought for the community.

The code already exists, but I didn't think it really fits into apr since
it's an 'anti-portability' feature :)  See...

Windows Registry and other similar repositories

Folks,



Would there be some way in APR to access the Windows Registry, and whatever
the analogs would be on other platforms?



Thanks.
