Hi, I got this mail. Since I never heard for something like FAM (but I did
have a strange dream about something like that) nor did I touch kdirwatch in
last year-or-so, I´m forwarding this here. Patches are ~6KB so I´d rather not
molest listserver with that.
Who works with kdirwatch now? Speak up, and I´ll send his patches.

thanks,
Sven

Hello Sven,

I most of the time work under IRIX; recently I tried the actual KDE2 snapshot:
and it's great! But I noted that kded used ~ 3% CPU load all the time and
I found that stating a bunch of NFS mounted directories every second caused
this load.

IRIX has a nice feature, the FAM (file alteration monitor), which is used e.g.
by the file manager and the mail tool. I updated the KDirWatch class to use it,
and it's doing quite good here (no CPU load any more).

As you seem to be the maintainer for this class: Can you look at the patch,
perhaps comment, and if you find it OK, commit it?

I'm not sure if I did the configure stuff right: For integration of FAM support
I check for the fam.h include file and compile things in according to the test
(seems right). This means adding fam.h to kdelibs/configure.in(.in):

	AC_CHECK_HEADERS( [snip] ... fstab.h sys/soundcard.h fam.h)
                                                             =====
For conditionally inclusion of libfam into libkio I changed the following line
in kdelibs/kio/Makefile.am to

	libkio_la_LIBADD = ../kdeui/libkdeui.la $(LIBFAM)

and added in kdelibs/configure.in(.in):

	AC_CHECK_LIB(fam, FAMOpen, [LIBFAM="-lfam"])  dnl for IRIX/FAM (JW)

This way $(LIBFAM) is set to "-lfam" when needed.

If you have a better way to add this without all the #ifdef's in the code please
let me know.

Greetings,
Josef
