I've been using clang for ports for a while now, and many ports will
build and run just fine using it.

I've been gradually adding to two lists of exceptions in
my /etc/make.conf -- those that absolutely require the base system GNU
compiler (USE_GCC?=4.2) and those that simply need *some* version of
gcc (for which I use gcc46 from ports (USE_GCC?=4.6).  Before defining
CC and friends to use clang, I first list these exceptions (I use
the ?= operator so these can still be overridden from the command
line).  So, the general format is:

#
# default to using clang for all port builds, with the following exceptions
#

# ports which will only build with the base system GNU compiler (4.2)
#
# the "make index" target also needs this

.if target(index) | \
${.CURDIR:M*/graphics/ImageMagick* } | \
${.CURDIR:M*/graphics/opencv*}
USE_GCC?=4.2
.endif

# ports which need *some* version of the GNU compiler (won't build with clang)
# use the highest version of gcc we have installed from ports (4.6)

.if ${.CURDIR:M*/accessibility/jovie*} | \
${.CURDIR:M*/accessibility/kdeaccessibility4*} | \
${.CURDIR:M*/audio/grip*} | \
${.CURDIR:M*/audio/rosegarden*} | \

USE_GCC?=4.6+
.endif

#

This, of course, doesn't fully address runtime issues, mainly just
build issues, but the same could be done for those, too.

For what it's worth.  :-)

Use sed.  


*GRIN*





As follows:

  sed -e ' t l
   :l
   /^[*]+$/ {
   N
   !/\n$/ { 
   P
   s/^.*\n//
   t l
   }
   /\n$/ {
   N
   !/\n\n[*]*$/ {
   P
   s/^.*\n//
   P
   s/^.*\n//
   t l
   }
   /\n\n[*]*$/ s/\n\n/\n\f/
   }  
   }'  

Note: "how" this incantation works is left as an excercise for the student. 
  Careful perusal of the FM will provide enlightenment.

Clang and ports

2012-02-01 Thread Joshua Isom 
I know that build cluster lists some ports that have problems with 
clang, but it doesn't say if they're tested or not.  I set up a clang 
jail to test out things before switching to clang for general use.  When 
I try running mencoder to encode a file to x264, it seg faults. 
Changing options doesn't change anything.  A gdb backtrace points to 
x264 being the problem.  Everything compiles and installs, but the 
build's useless.  Is clang ready for ports, or is it only safe for 
kernel/world?

If you want to know the meaning of a particular sysctl, then 'sysctl
-d' is your friend:

# sysctl -d vm.pmap.shpgperproc
vm.pmap.shpgperproc: Page share factor per proc
# sysctl -d vm.pmap.pv_entry_maxvm.pmap.pv_entry_max
vm.pmap.pv_entry_max: Max number of PV entries

(OK, granted, you may wish to know more than is provided by just these
terse single-line entries, but it's a start along the clue path, at
least)

Your mileage may vary, but for me personally, I like to have *some*
sense that I'm approaching this sort of problem in an organized,
methodical manner, rather than simply pulling numbers out of a hat, so
to speak.  So, since computers are based on the binary number system, I
naturally gravitate towards numbers that are nice, neat multiples of
some power of 2, such as 64, 128, 256, 512, 1024, 2048 and so on.

There's really no hard-and-fast rule for determining a good setting for
many of these numeric-type sysctls.  The method I generally use is:

First, try to find a similarly named sysctl within that same hierarchy
that represents the current working value for the sysctl in question,
by lopping off the last element of the sysctl and scanning the results,
using 'sysctl -d' again on the most likely candidate(s) to be sure.
For instance, since we're dealing here with two members of the vm.pmap
family:

# sysctl vm.pmap

vm.pmap.pat_works: 1
vm.pmap.pg_ps_enabled: 1
vm.pmap.pv_entry_max: 7573622
vm.pmap.shpgperproc: 1024
vm.pmap.pde.demotions: 14959
vm.pmap.pde.mappings: 1055
vm.pmap.pde.p_failures: 255640
vm.pmap.pde.promotions: 23441
vm.pmap.pdpe.demotions: 5
vm.pmap.pv_entry_count: 270500 <--- this looks like a likely candidate
vm.pmap.pc_chunk_count: 2590
vm.pmap.pc_chunk_allocs: 1551162
vm.pmap.pc_chunk_frees: 1548572
vm.pmap.pc_chunk_tryfail: 0
vm.pmap.pv_entry_frees: 244822815
vm.pmap.pv_entry_allocs: 245093315
vm.pmap.pv_entry_spare: 164620
vm.pmap.pmap_collect_inactive: 0
vm.pmap.pmap_collect_active: 0

# sysctl -d vm.pmap.pv_entry_count
vm.pmap.pv_entry_count: Current number of pv entries

Comparing the current working value to the defined maximum value here,
it's pretty obvious that the problem doesn't lie with
vm.pmap.pv_entry_max, so it's more likely that (were I experiencing a
problem) the value of vm.pmap.shpgperproc needs to be increased.

How I choose the value also depends on what the number represents.  If
it's determining the size of a buffer or some other chunk of memory, I
bump the value up to the next (or second) nearest multiple of, again,
some reasonable power of 2 (64, 128, 256, 512, 1024), since computers
"like" such nice, "neat" numbers.

In the case of items that set a limit on the number of entries in some
sort of array, such as vm.pmap.pv_entry_max, I usually just double the
default setting and see how that works, perhaps backing it off a bit
later by some "sensible" factor.

If the problem persists, just bump it up again by a similar factor
until it goes away.

You may, in time, devise your own methodology, but the one I just
described is "comfortable" for me, and does feel a lot better than just
haphazardly plugging in random numbers and hoping for the best.

HTH

some kind of binary sed(1) command

2012-02-01 Thread Matthias Apitz 

Hello,

I have a normal ASCII file wich has in some places two lines of '*',
separated by an empty line, i.e.

\n
*\n
\n
*\n
\n

and I want to substitute the \n between the star lines by \f; the
'binary' sed command would just be 

s/*\n\n*/*\n\f*/

which ofc does not work with sed(1) because it is line oriented;
I could write something in perl, C, awk or whatever language, but I
would prefer to do it with the normal commands... any ideas?

Thanks

Identifying at jobs

2012-02-01 Thread Toomas Aas 

I've been curious about this for a long time.

Say I have three jobs scheduled with at, as seen with atq:

# atq
DateOwner   Queue   Job#
Thu Jan 12 22:12:00 EET 2012rootc   6931
Fri Jan 13 03:44:00 EET 2012rootc   6932
Fri Jan 13 04:01:00 EET 2012rootc   6933

How do I tell which job does what? I can see the files corresponding  
to jobs in /var/at/jobs:


# ls -l /var/at/jobs
total 8
-rw-r--r--  1 root  wheel 6 Jan 12 18:05 .SEQ
-rw---  1 root  wheel 0 Dec 10  2007 .lockfile
-rwx--  1 root  wheel  1096 Jan 12 12:15 c01b130151521c
-rwx--  1 root  wheel  1096 Jan 12 17:45 c01b1401515368
-rwx--  1 root  wheel  1091 Jan 12 18:05 c01b1501515379

If I look into one of the files, say c01b1501515379, I can see the  
command I have scheduled at the end of the file. But how do I tell  
which of these files corresponds to which Job# in atq output? I'd like  
to remove one of the jobs with atrm, but I can't figure out, which job  
I need to remove.

What is the program doing? I/O can significantly limit OMP value. Also,
you need to make sure you code your loops properly or else you have a
single-threaded application, without warning.

As an example, this is one of my key sections of code in C++. It works.
I can't say for Fortran.


#pragma omp parallel

OpenMP on FreeBSD

2012-02-01 Thread Anton Shterenlikht 
I'm new to OpenMP. I wonder
if there are any special considerations
when running OpenMP on FreeBSD?

For example, I have this OMP parallelised
fortran program, nested do loops, compiled
with gfortran46. When I run it with 2 threads
on a 2-cpu box, I see in top(1):

  PIDUID   PRI NICE   SIZERES STATE   C   TIMECPU COMMAND
63995   1001890 57048K 34272K CPU11   1:06 55.08% dummy.sx{dummy.sx}
63995   1001870 57048K 34272K RUN 1   1:02 52.39% dummy.sx{dummy.sx}
   11  0   155 ki31 0K32K RUN 0 376:58 51.46% idle{idle: cpu0}
   11  0   155 ki31 0K32K RUN 1 368:18 45.36% idle{idle: cpu1}

I wonder why, even after a minute of run time,
I still have nearly a whole cpu idle?

As a result the run time with 2 threads
is nearly identical to run time with 1 thread. 

It's likely that I'm not using OMP correctly,
but I wanted to check if there are any
special FreeBSD related issues to bear
in mind when coding with OMP.

libXext fails to build on 9.0-RELEASE/amd64

2012-02-01 Thread 1126 


Hello list!
Today, I installed a fresh 9.0-RELEASE/amd64 and wanted to install  
Xorg. There were no other packages installed before, so Xorg and all  
it's run- and build-dependencies would be the first. But it fails. The  
error message reads:


...
checking for XEXT... configure: error: Package requirements (xproto >=  
7.0.13 x11 >= 1.1.99.1 xextproto >= 7.1.99) were not met:


No package 'x11' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you  
installed software in a non-standard prefix.


Alternatively, you may set the environment variables XEXT_CFLAGS and  
XEXT_LIBS to avoid the need to call pkg-config.

See the pkg-config man page for more details.

===> Script "configure" failed unexpectedly.
Please report the problem to x...@freebsd.org [maintainer] and attach  
the "/usr/portx/x11/libXext/work/libXext-1.3.0/config.log" including  
the output of the failure of your make command. Also, it might be a  
good idea to provide an overview of all packages installed on your  
system (e.g. an 'ls /var/db/pkg').

*** Error code 1

Stop in /usr/ports/x11/libXext.
*** Error code 1


After reading this, I asked Google, but it didn't came up with a  
solution. I updated the ports (portsnap fetch update), but that didn't  
help either. I tried to install only libXext (make install clean), but  
that didn't work either.


Does anyone knows a solution?


As has been asked, I append the output of "config.log" from the

2Wire Router and Host Discovery

2012-02-01 Thread Chris Maness 
I have a twire modem/router that has 5 static IPs assigned to it.  It
configures the firewall settings by discovering the hosts (by means
unknown to me) and allowing you to go into the firmware menu and
setting each host individually.  Once the hosts are recognized it
sends arp requests every few seconds to see if the host is still up on
the local network.  Incoming traffic is then routed to that static
address without a traditional arp requests because the router already
has that MAC address bound to that IP.

Now for the problem.  I have a virtual host running on one of the
boxes on the local network.  The virtual host does not show up on this
list even though the guest OS has a manual entry in the hosts arp
table, and it is pingable from the local network.  The host OS
responds to ARP requests for that IP and correctly route for that
ping, but this guest OS never shows up in the router.  That makes it
impossible to configure firewall rules and allow traffic into this
guest OS.

How does this Twowire router discover static hosts on the local net?
The Cisco router that I was behind in the past had no issues with
this.  If a ping came in from the outside world it would just arp for
that address and cache the response just like any other host on the
local net.

AT&T is just suggesting that I buy a Motorola router and be done with
it.  I would prefer to fix it in software if I can.

Any suggestions and advice on this?

Thanks,
Chris Maness

You could use a combination of nullfs and unionfs. Below is is what I do to
share /usr/ports on the host with a jail, but keep the jail from writing in
the host's tree.

host# cd /usr/local/var/jails/192.168.0.100/usr
host# mkdir tmp/foo
host# mount_nullfs /usr/ports/ ports/
host# mount_unionfs -o noatime tmp/foo ports/

With this, the jail sees the hosts' /usr/ports tree, but when it wants to
write there, the written files end up under tmp/foo in the jails' tree.

They seem to have failed because they couldn't find the package on the
download site. Other errors I got were that the package it had downloaded
had an "unrecognized format".

I did not save them, there is really no way to save a copy of them unless I
copy them by hand. I will have to rerun the commands to get the error
messages and then transfer them by hand.

What is your DM and does it save logs? You can find some hints there.

I'm not sure I get what you're trying to do here.

Is there a reason you do not set your carp interfaces' advskew, vhid and
pass in /etc/rc.conf ?

Also, I notice in state 2 your password for carp0 is tnewpass, while the
other ones are newpass.

carp+devd+ifstated on master problem

2012-02-01 Thread peter knezel 
Hello all,

I have configured devd and ifstated on a master FreeBSD server (slave
not changed so far) on which carp was configured with three
carp0,carp1 and carp2 virtual addresses.

When I as root do ifconfig carp0 down and up, the corresponding
testdown.sh and testup.sh
scripts are run (defined in ifstated.conf).
The status of carp0 interface changes to INIT then to MASTER (after
ifconfig carp0 up).

However this is not valid when doing the same with carp1 or carp2.
It goes to INIT+testdown.sh executed but then immediately afterwards
it goes to MASTER+testup.sh executed.

What can be the problem?

cd /usr/local/etc
cat ifstated.conf
init-state one

net = '( "ifconfig -a -u |grep carp0 > /dev/null" every 3 && "ifconfig -a -u
|grep carp1 > /dev/null" every 3 && "ifconfig -a -u |grep carp2 > /dev/null"
every 3)'

state one {
   if ( ! $net ) {
   run "/sbin/ifconfig_carp0 vhid 1 pass newpass 192.xx.xx.1/24"
   run "/sbin/ifconfig carp1 vhid 2 pass newpass 192.xx.xx.2/24"
   run "/sbin/ifconfig carp2 vhid 3 pass newpass 192.xx.xx.3/24"
   run "/usr/local/testdown.sh"
   set-state two
   }
}

state two {
   if ( $net ) {
   run "/sbin/ifconfig carp0 vhid 1 advskew 100 pass
tnewpass 192.xx.xx.1/24"
   run "/sbin/ifconfig carp1 vhid 2 advskew 100 pass
newpass 192.xx.xx.2/24"
   run "/sbin/ifconfig carp2 vhid 3 advskew 100 pass
newpass 192.xx.xx.3/24"
   run "/usr/local/testup.sh"
   set-state one
   }
}

In addition I had to configure devd.conf to have ifdown.sh and ifup.sh
scripts executed when reboot is done on the master.

notify 30 {
match "system" "IFNET";
match "subsystem" "carp0";
match "type" "LINK_UP";
action "/usr/local/etc/rc.d/ifdown.sh";
};

notify 30 {
match "system" "IFNET";
match "subsystem" "carp0";
match "type" "LINK_DOWN";
action "/usr/local/etc/rc.d/ifup.sh";

Thanks for any suggestion in advance.

I'm at a loss here and don't know where to continue debugging this error.
Does anyone experiencing the same problem?

Re: limit on PV entries

Did you explicitly disabled superpages?
What is the output of $ sysctl vm.pmap.pg_ps_enabled ?

Re:[SOLVED] bash LC_COLLATE or LC_ALL set “C” not sort in dictionary order.

   Hi,

   Been trying to get BASH to sort set characters in  dictionary order.
  I typed "locale" and it shows LC_COLLATE and LC_ALL are set to "C"
thought that was enough to work,
  however when i type metacharacters:  set character; any character,
something like this:

  ls  [a-cx-y]*

   bash does not sort in dictionary order; file   "Binarc" does not
list.


*OF*COURSE* it doesn't.  Unix is _case_sensitive_.  You specified a lower-
case only (in the C locale) pattern.  Naturally, it doesn't match a file
with an upper-case character in it.

Note: in the 'C' locale, characters are sorted on the underlying byte value.
Thus you will get all the upper-case matches before any lower-case match.

To get upper-and-lower case files in the C locale, you will have to use:
ls [A-CX-Ya-cx-y]*

IF you speciy a different charset for collating, you _may_ get upper/lower
case characters sorted adjacently.  See the specifications for the charset
in question.



  Thanks for reply!

   I meant LC_COLLATE being  set to en_US.UTF-8 not C.

AH.  you lied (not necessarily maliciously, or intentionally) about the
nature of the problem.  disregard my rant.

The short answer to the revised situation is 'it depends on how the charset
collating sequence is deifined'.  AND _which_ release of FreeBSD you are
using, and thus which version of bash.

   I have been digging around and discovered  linux's bash is  not 
working correctly on this matter and numerous  users  have file bug 
reports about it.  FreeBSD's bash is fine:


   https://bugs.archlinux.org/task/24553
   https://bugs.launchpad.net/ubuntu/+source/bash/+bug/120687
   http://teaching.idallen.com/net2003/06w/notes/character_sets.txt

i will continue using either character classes and upper/lower case 
charsets when defining wildcards

   thanks for the help.

While your offer is made with the best of intentions, I doubt the

problems, it offers far too much opportunity for people up-to-no-good to
be able to introduce trojans, spyware and so forth.


No no, i didn't said i will make them manually, i wanted to said that 
i can add one server amd64 to the pool of automate servers that make 
the packages, i think it works automatically and distribute workload 
like boinc or other similar net. About the people which introduce 
trojans, rootkits etc... i didn't think on that issue and is really a 
very important stopper.


With the rest of your mail, i agree with you, my idea was completly 
halfthinked (is it the correct word?).
