Re: sleep is not working to avoid starvation among threads of same priority
Hello, Take a look at pthread_yield(): DESCRIPTION The pthread_yield() forces the running thread to relinquish the processor until it again becomes the head of its thread list. (Note that it is not portable) And if you want to use sleep, I found out that using sleep with more ms does 'yield' the thread/process. iirc, 20ms was enough to stop it from using 100% CPU. -- Jille Ramachandran Sathyanarayanan wrote: Hi I hope this is the right mailer for this question. pls let us know your inputs on this.

So, to avoid starvation I am processing 1000 iterations of for loop(that of thread B) in one batch and giving sleep of 1ms, but still thread A is starving. If I increase the batch size used in for loop from 1k to 10k then starvation of thread A is little less whereas it should be more as Im increasing processing time of thread B. I tried various combinations of sleeps and batches, but I couldnt solve the starvation of thread A. Is the sleep right solution? I will be grateful if someone could answer on this.

readdir(somefile) returing inconsistent errors
Hello, I was looking through some vop_readdir()'s, and noticed an inconsistency between (at least) xfs and unionfs. sys/fs/unionfs/union_vnops.c:1410: if(ap-a_vp-v_type != VDIR) return (ENOTDIR); sys/fs/xfs/FreeBSD/xfs_vnops.c:1001: if(vp-v_type != VDIR) return (EPERM); A little userland script gave me a ENOTDIR when trying to opendir(somefile) (userspace opendir() calling kernelspace readdir()). So I assume the check is made earlier, but shouldn't the xfs code return ENOTDIR in this case ? due to the if-clause above it, you'd say ENOTDIR seems better than EPERM. -- Jille ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
Filtering items in readdir() with own fs
Hello all, information skipable=yes I am trying to create a filesystem that works exactly like nullfs, but hides all .svn dirs (and contents) (Yes, I started with svn cp). I've got it working so far that it denies that the dirs and contents exist (grep isn't complaining; so I can finally grep -r through the source). But it would be nice if I can also hide the .svn dirs in dir listings. /introduction problem I have been looking through a few existing filesystems (unionfs, fdescfs, xfs, devfs). None gave me a good way for hiding specific entries in the listing. With some help of unionfs I have created a direct-pass-through using VOP_READDIR(), but I can't filter it with that. I tried using some xfs code, but didn't get any result with that. /problem question Can anyone give me a hint on where to start looking for code that could be used with filtering functionality ? Any file or function ? /question Thanks in advance, -- Jille ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: command-line bittorrent utility

A callback mechanism of some kind is fine as long as it doesn't require polling. This is for distribution of files within a LAN and WAN: I have some large files that I need to distribute to many machines, and pushing them all out multiple times from the server is inefficient. Things that come close: * The python implementation, but it doesn't seem to work very reliably. I get errors and exceptions from both the client and server when transferring a file with only two machines participating. * http://www.murmeldjur.se/btpd/ is a daemon with command line client.

Trying (not) to crash with libpthread (6.3-RELEASE)
Hello,
I'm trying to catch SIGSEGV, to be able to run 'unchecked' (possibly
crashing) code.
And not letting the entire program die, but just kill that thread.
So I wrote some testing code.
But, I ran into a problem; the signal-handler does not work when a
thread is created (or something like that).
The code below crashes on SIGSEGV, but should die in void sigcatcher(int);
If you uncomment the crashingthread(NULL); line, it will die in the
signal handler.
pthread_create seems to take over signal handling.
I quickly checked some pthread source, and it seems that it should call
my own handler.
(There might be an exception for some signals, but I didn't found that)
Can anyone explain me what is happening here ?

Re: binary file within a shell script
It's not exactly what you are looking for: But you could take a look at shar(1). I don't even know for sure whether it can archive binaries. shar gives you a shellscript, to which you could prefix your own script, and when you run it, it'll extract the incorporated file, and you can exec it :) -- Jille (Resend from right email-adres) Mathieu Prevot wrote: Hi there, I would like to use one exec file from a shellscript but I would like it to be incorporated in the same file, like Nvidia do for its FreeBSD drivers.

Re: devctl (alike?) for devfs

Is it possible to get notifications about changes in devfs - appearance and disappearance of devices (in devfs sense of the word)? devctl currently notifies about real (hardware) devices handled by device drivers and some notifications about hardware/driver events. But what if I want to automatically run some action if /dev/ufs/magic-label appears? Or if I want to monitor appearance and disappearance of ad* and da* devices (without having to monitor low level drivers like umass)?
