Re: cannot print to remote printer
I wrote: The new POSIX draft, at least, sanctions the automatic reset of SIGCHLD to SIG_DFL upon exec(). Terry Lambert appears to have written: How does the NOHUP program continue to function in light of this reset demand? There is no ``demand'' involved. The behavior of the system when SIGCHLD is set to SIG_IGN has always been entirely implementation-defined. The new specification makes it clear that, in the course of this implementation-defined behavior, implementations are free to reset SIGCHLD to SIG_DFL when a new program is executed. The new specification also makes it clear that the behavior of functions such as system() and pclose() is undefined when SIGCHLD is set to SIG_IGN. (The semantics for SA_NOCLDWAIT are somewhat different.) This change was made because some implementors interpreted the base documents as requiring that SIGCHLD be inherited across exec(), which would then in turn require every program which ever makes use of wait() to explicitly reset SIGCHLD (since the nominal default could not be depended upon). Giorgos Keramidas wrote: I'm not sure about POSIX, but the manpage of nohup does not mention SIGCHLD. The only signals I see mentioned in revision 1.8 of nohup.1 are SIGHUP and SIGQUIT. That is correct. SIGCHLD is entirely irrelevant to `nohup', as the slightest amount of effort on Terry's part would have made clear. -GAWollman To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-current in the body of the message

Hello All I have just cvsuped and now I am trying to make buildworld with no luck. I'm getting the following error and I have no idea where to begin to fix this.

Re: Latest version of mega header file POSIX update
Back on March 15/2001, Garrett Wollman wrote: I have finally produced another version of the big header file patch for people to look at. I'm still running an older (January) kernel and world based on these changes. I have verified that these still build on i386-architecture systems. I'm looking for some people to do the following: 1) Look at the changes to machine-dependent i386 headers and make analogous changes, or verify the changes I've made, in the Alpha and IA64 code. 2) Test it. I'm interested not only in whether it runs -- I'm fairly confident of that -- but also in what external software it breaks, if any. I'm expecting to make a third pass over the header files once Austin Group draft 6 is issued. (Draft 7 is expected to be the final text.) However, I really, really want to get this checked in so that we can all have a framework on which to work. The patch has now gotten too large for some e-mail systems, so I'm making it available via the Web at http://khavrinen.lcs.mit.edu/includes.patch. As I'm sitting here picking off the occasional compile-time warnings in lprfriends, I'm wondering about the status timeline of this big posix-push patch. (one of the warnings I'm getting would be solved by the changes to grp.h in this patch). Is the goal to have this patch in current for 5.0-release later this year? If so, what milestones should we be shooting for? Is this going to show up in 4-stable too, or is it too widespread a change to try and MFC it? (I am not suggesting it SHOULD be MFC'ed, I'm just wondering). [also, it seems to me there was a more recent message about this patch, but it seems I didn't save that one] I've got this idea of trying to build an alternate /usr/include on my -current machine, and then see how it works by switching between the current /usr/include and an alternate version which included the latest version of this patch. On the other hand, I do a lot more day-to-day living on a -stable system, so I'm not sure how much of a test I'd give these changes on my -current system. -- Garance Alistair Drosehn= [EMAIL PROTECTED] Senior Systems Programmer or [EMAIL PROTECTED] Rensselaer Polytechnic Instituteor [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-current in the body of the message

Removing the random device from the kernel config fixed the problem. So you don't happen to be doing anything similar are you?

Only one exception beats off everything. union_dircheck() in fs/unionfs/union_subr.c may replace f_data with a new vnode. That code really scared me, but on careful inspection, the f_data is actually protected by the vnode exclusive lock from concurrant getdirentries() calls. (getdirentries() calls union_dircheck()) The code is still troublesome for mixing read() and getdirentries() at the same time, but since union mounts are rare we should leave it along and possibly revisit this later. My opinion is that you never need a lock for an assignment, unless that assignment spans multiple dependant operations or is dependant on some pre-condition, cases: /* no lock */ foo-a = 5; /* needs lock */ if (foo-b) foo-a = 5; /* might need lock to protect agianst inconsistant view */ foo-a = 5; foo-b = c; -- -Alfred Perlstein [[EMAIL PROTECTED]] Ok, who wrote this damn function called '??'?
