On non-linux unix systems, one can reference __iob[] to find all currently fopen()ed files (e.g. when forking a new process one would generally want to flush their buffers first, or perhaps close most of them). Linux's stdio.h doesn't provide such an array of open FILE pointers, or at least if it does I can't find it. This seems to be a glibc question. Folks on news:comp.os.linux.development.[apps|sys] might know better. Referencing internal data structures is inherently non-portable. You might look in /proc/pid/fd/ which seems to have file descriptor numbers represented as symbolic links to the file(s) opened. fflush (NULL); flushes all fopen'ed files, but that doesn't mean writes are actually committed (you need sync/fsync for that). Any idea what they call it, or how one can find all currently open FILEs? Perhaps there is a better way? A general guide to porting underlinux /debian would be appreciated.

Correct. Two ISO C forms of main are:
int main (void) { ... }
/* identical to: int main () { ... } */
or
int main (int argc, char *argv[]) { ... }
/* identical to: int main (int argc, char **argv) { ... } */
However:
int main ();
and
int main (void);
are not identical *declarations*. But only crazy people who like to
call main recursively ever write declarations for it...
In non-conforming mode (the default), gcc will also accept void main(...)
and the three argument form that adds char **envp...
And then, there is the KR form with implicit int return:
main (argc, argv)
int argc;
char *argv[];
{...}
KR is accepted but deprecated in all versions of ISO/ANSI C except the
implicit int return type is an error in C99.

Could you specify a linear list more clearly? - the
contrary would be a nonlinear list which on the first
view seems to be self-contradictory.
For example, in C:
int fib(int n)
{
if (n 2)
return n;
return fib(n-2) + fib(n-1);
}
the rules require that fib(n-2) is called before fib(n-1). In Scheme:
This is incorrect. There is no sequence point in the statement:
return fib(n-2) + fib(n-1);
So, it's up to the implementation which side of the '+' is evaluated
first.
(define (fib n)
(if ( n 2)
n
(+ (fib (- n 2)) (fib (- n 1)
The C and Scheme functions are essentially identical. In C, statements
are executed in order. I'm not too up on functional languages, but I
seem to recall they need special syntax to execute statements
sequentially.
That fib function is painfully slow via recursion and susceptible to
uncaught overflow in the C version (Scheme has big numbers built in).
#include stdio.h
unsigned long long
get_nth_fib (unsigned long long count)
{
unsigned long long last2 = 0ULL;
unsigned long long last = 1ULL;
unsigned long long cur = count;
unsigned long long i;
if (count 1) {
for (i = 1; i count; ++i) {
cur = last + last2;
if (cur last) {
fprintf (stderr, get_nth_fib(%llu) overflows!\n, count);
cur = 0UL;
break;
}
last2 = last;
last = cur;
}
}
return cur;
}
Less elegant, but much faster and more robust than the recursive C version.
A table look-up would be even faster up to some 'n' (say, 93 in this case).

I've written many myself. Yet, in fact, there is no concurrency support at all in those languages. Yes, it isn't much of an argument for. As I inidicated originally, I just was pointing out the capability but don't have enough experience to argue the merits of one approach vs. another. I've looked at what is involved for C to do threading vs. Ada, and the Ada approach is at least superficially much cleaner (as it is part of the language design). Also, the tasking mechanism is supposed to be available even when the underlying OS doesn't have direct support (say DOS). It is up to the compiler/run-time to handle the platform details... 3 * a call on a protected subprogram of a protected object, providing exclusive read-write access, or concurrent read-only access to shared data; What makes a subprogram protected? Is this a keyword or something that the programmer has to put in the right place, like Java's synchronized? I don't know Java, but protected is a keyword. But, you don't just stick it anywhere anymore than you would stick class wherever. 8 In addition, tasks can communicate indirectly by reading and updating (unprotected) shared variables, presuming the access is properly synchronized through some other kind of task interaction. This sounds like thread synchronization is the programmer's problem, at least for the case of unprotected variables. AFAIK, yes. This all sounds considerably more portable than C threading (which is dependent either on calling OS services directly, or using a third-party library that may not be available on all platforms, or may have licensing issues), but not necessarily all that much better. The crucial point, to me, is that for at least the most common kinds of thread communication and data sharing, it should not be necessary for the programmer to remember to do anything extra (like mark functions or variables with a special thread-safety keyword). Erlang meets this requirement in spades; I don't know of another language that does. Ada is really fairly low-level like C or C++. I have not investigated Eiffel much, but people seem to ooze affection when talking about it. So, I'd be interested to see if/how it approaches the matter.

I have never learned Ada, partly because I've never needed to and partially because it's never attracted my interest, in part due to its reputation as the PL/I of the '80s (translation: a vastly overcomplex, I've been recently attracted to Ada due to its ability to catch many more errors at compile time than C (meaning, less bug hunting). I was shocked when I first started using it how many things the compiler would complain about. One tricky bit is the visibility rules, esp. in relationship to operators. Anyway, I think it is much maligned simply as a reaction to its origin w/ the US DOD or because of its Pascal'ish syntax. From chapter 9 of the Ada95 Reference Manual w/ Tech. Corrigendum 1: (http://www.adaic.com/standards/95lrm/html/RM-TTL.html) Section 9: Tasks and Synchronization 1 The execution of an Ada program consists of the execution of one or more tasks. Each task represents a separate thread of control that proceeds independently and concurrently between the points where it interacts with other tasks. The various forms of task interaction are described in this section, and include: 2 * the activation and termination of a task; 3 * a call on a protected subprogram of a protected object, providing exclusive read-write access, or concurrent read-only access to shared data; 4 * a call on an entry, either of another task, allowing for synchronous communication with that task, or of a protected object, allowing for asynchronous communication with one or more other tasks using that same protected object; 5 * a timed operation, including a simple delay statement, a timed entry call or accept, or a timed asynchronous select statement (see next item); 6 * an asynchronous transfer of control as part of an asynchronous select statement, where a task stops what it is doing and begins execution at a different point in response to the completion of an entry call or the expiration of a delay; 7 * an abort statement, allowing one task to cause the termination of another task. 8 In addition, tasks can communicate indirectly by reading and updating (unprotected) shared variables, presuming the access is properly synchronized through some other kind of task interaction. Static Semantics 9 The properties of a task are defined by a corresponding task declaration and task_body, which together define a program unit called a task unit. Dynamic Semantics 10 Over time, tasks proceed through various states. A task is initially inactive; upon activation, and prior to its termination it is either blocked (as part of some task interaction) or ready to run. While ready, a task competes for the available execution resources that it requires to run. NOTES 11 1 Concurrent task execution may be implemented on multicomputers, multiprocessors, or with interleaved execution on a single physical processor. On the other hand, whenever an implementation can determine that the required semantic effects can be achieved when parts of the execution of a given task are performed by different physical processors acting in parallel, it may choose to perform them in this way. -- ...the plural of anecdote is [not?] data. - attrib. to George Stigler -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

People used it for basic e-mail. People used the address book. But the extent of the group calendaring was that some people would send meeting requests out. I think one person had a public calendar, but most of us hadn't bothered to learn how to access it. And most of the other groups were less technical than the one I was in. Is this pretty typical? Or do other places actually make real use of the group calendars? Or is it that the only people who really know how to use all the features are the people who aren't doing real work (like the phone system in some places)? I'd say that's pretty typical. Sometimes bosses delegate to clericals to arrange meetings and it's nice when you can look up everyone's availabilty. However, that falls apart as soon as you add an outside party to the meeting.

Re: Using exim efficiently on a dialup machine
On Mon, Sep 09, 2002 at 09:49:00AM +0200, Joerg Johannes wrote: Hi List Some weeks ago I switched from kmail to mutt/exim. At first I did not realize that exim did not deliver several e-mails, some to the list, and some private ones. I saw using exim -bs -bp, that those mails are marked '*** frozen ***'. I don't know why this is the case, I'm sure I was online when sending them from within mutt. So, how can I defrost the frozen messages and get them sent? How do I configure exim so that it looks if ppp0 is up and then retries to send the messages instead of freezing them? (Is this possible at all?) Or what is the favoured way for a dialup machine to send mails from within mutt? The messages might be frozen because after an extended period of time, exim was unable to deliver them. A standard setup to use exim from a dialup is to have it send messages via your ISP's SMTP server (rather than trying to deliver them itself). If you're off-line, and send a message via mutt (or whatever) the messages are normally queued for delivery. By default, there's probably a cron script that runs exim every five minutes or so (unless it's running as a daemon). Additionally, /etc/ppp/ip-up.d/exim should be run when the connection comes up, and then flush the queue. So, long story short, either exim is misconfigured for delivering mail, or the messages couldn't be delivered (network outages, unresolved hosts, etc...). You might want the -Mt argument for thaw message(s) with ids ... The messages will be located in /var/spool/exim/. You might also check /var/log/exim for info about the delivery failures. Apparently there is also an auto_thaw configuration option... -- begin 664 .signature MF5L;E-(Y'(-ID4@/G1E;BYSI`,FUG93P)`@(`@(`@(`@(`@( M`@(`@(`@(`@(`@(`A%FEC($N($UI;QEB`\96=M,D!J',N;F5T /@H` ` end -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Re: consistant userid:username setup for system accounts?
On Sun, Sep 08, 2002 at 12:24:06PM -0700, nate wrote: hi I have ran accross this a few times in the past but was curious if there was any effort in Debian 3.0 that goes to assigning a uid number to the system accounts to keep them consistant accross installations. Many of the accounts already are(the core ones) but at least in my case I had some trouble migrating a cyrus installation from one system to another because on the system it came from(potato) cyrus was uid=100, on the woody system it was going to cyrus was uid=103 and sshd was uid=100. On my system at home which is woody cyrus is uid=101 and sshd is uid=102. It would really be nice if there was an assigned method(sort of like assigning ports) for keeping uid numbers consistant. This would also help a great deal with distributed authentication such as LDAP or NIS. at least it would help when working in a mostly debian networked enviornment. The Debian policy manual section 10.2 covers users and groups. Specifically, the uid/gid numbers 0-99 are explicitly assigned via base-passwd, 100-999 are dynamically assigned system uid/gid's. So, it seems that any package that doesn't need an explicit uid/gid gets the next available system uid/gid via adduser --system. I would assume that system packages are only thought to need consistent id's when they actually own files (vs. root.root config files). One hundred id's isn't very many to go around. -- begin 664 .signature MF5L;E-(Y'(-ID4@/G1E;BYSI`,FUG93P)`@(`@(`@(`@(`@( M`@(`@(`@(`@(`@(`A%FEC($N($UI;QEB`\96=M,D!J',N;F5T /@H` ` end -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Re: Why wdm opens a TCP port?

I'm going to guess it's only listening on the local loopback. Also, try telnetting to the address:port. Does it hang and time out? Do you get connection refused? It would seem WDM sets up a TCP port to communicate between a parent and child (more than one WDM process running?) and therefore doesn't really care what port is used (lets the OS decide). -- Eric G.

I have to admit that I don't know the purpose of this open port, but for example gdm, which I've used in some other boxes, doesn't, at least by default, open any ports. Edit /etc/X11/wdm/Xservers and add '-nolisten tcp' to the line that looks like :0 local /usr/bin/X11/X See if that fixes things. If not, then it's a bug and I must fix it since I am the wdm maintainer. Only thing is, the X ports are 6000-7, according to /etc/services. Sure the 1030 port is not for some local use only? Is it always the same port? The ports doesn't appear to match any reserved ones in /etc/services... Don't use wdm myself, so... -- Eric G.

No. 'Cause if you don't have the priveledge already, a call to
setuid won't give it to you. But, you can give up priveledge.
If you are root and want to run it as someone else, then:
su -c cmd
will do it without asking for a passwd.
If you're root, and want to run the command as another user, you
have to specify which user. That is what the OP wanted to do.
If you are not root and want to run it as root, then:
* Use one of the setuid script wrappers around. I don't know of any
off the top of my head, but they must be around.
* Write your own setuid script wrapper in C. It's not hard - it goes
something like this:
#include unistd.h
int main( int argc, char** argv )
{
execve( argv[0], argv[1] );
return 0;
}
chown root setuidscriptwrapper
chmod u+sx setuidscriptwrapper
or something of that order. Control *very* closely who has permission
to run this script.
Lucky for you, you're wrapper won't compile. Semantically, it'd invoke
endless recursion anyway. All around, this is a bad idea. You might as
well remove the root password.

I would like to have it running to provide time synchronisation for all my machines, so I would like it to start at boot. However, I do not want it to dial up regularly, which would suggest that I should start it up at dial up. Consider chrony which has ppp scripts for up/down behavior. I've been using it for years now without intervention... I am (thinking about) trying to devise scripts to control things. For services that don't have up/down scripts for ppp already, you may have to do this. Not too hard... It should be possible to bring up services at boot, so that they only service the local domain. Then, on sucessful dialup, to restart them in a mode that will make use of the link. When the dialup is broken then it reverts to the original setting. Of course, this means that everything will start up at the same time, and they will all probably monopolise the phone link. So we need to prioritise the services and so allow the user who brought the link up to get reasonable service. Of course, I would like to be able to upgrade packages without having to re-edit all the scripts. I am sure that I am not the only person to want to do something like this. Packages are supposed to ask before touching modified init scripts on update... Sometimes, your scripts may get broken by significant changes though (so be prepared). -- Eric G.

In fact, it may be an easy implementation of the heap sort. Anyhow, when I was looking back at the data, the same Nlog2N factor came out, and www.nr.com at least claims that they actually get that in their worst case. In which case, they may be mathematically equivalent. The two methods are, at least, conceptually equivalent in terms of the general method. So if you wanted to use a standard algorithm, I guess I'd advocate the heapsort. But it's not quite the same as the one I described. In an approximate way, you've described a merge sort which is generally the preferred method of sorting linked lists and runs in N Log N consistently. The main difference from your description is that the list is recursively divided in half and then merged back together in sorted order. When all the recursion returns you perform the final merge and then have a sorted list. For a linked list, it doesn't require any extra space, which is nice. For arrays, quicksort is likely to do as well, and possibly better. But for 50 items, you could use a bubble sort or insertion sort and not notice a performance hit. -- Eric G.
