For anything but 21, the regex is only two numbers! You need to enclose the
alternatives in () or (?:), depending on whenever you want to capture them
or not.
That aside, please be very mindful that \d and . are both code smells. The
former will match much, much more than just [0-9] -- grab the unichars[0]
program from Unicode::Tussle[1] if you want to see for yourself. Either use
the /a switch (or the more localized form (?a:), bot available in newer
Perls), or [0-9], or \p{PosixDigit}, or (your favorite way here. TIMTOWTDI
applies).
The dot is also problematic. You aren't using the /s switch, so it actually
matches [^\n].
Correct.
Is that what you want? Are you certain that no one is going
to come and, after reading Perl Best Practices, will try to helpfully but
wrongly add the /smx flags and screw up your regex?
It doesn't really matter because the regular expression is matched
against a line (via readline) and as such will only contain one
newline and that newline will be at the end of the line so it will
match the same with or without the /s option.
Also, as the regular expression does not contain either the ^ anchor or
the $ anchor it will match the same with or without the /m option.

Perl Fork and writing to stdout
Hello Perl People
I was wondering if someone could enlighten me on an observation I
have been seeing..
A little Background info:
Where I work we have been seeing very slow ssh connections times
(it's not DNS. Maybe NIS, NFS, but definitely not DNS).
Anyways I wanted to write a script that would log the time it
takes to connect to a remote server via ssh and issue a command (uname
-n). The tricky part was that I wanted the remote connections to kick
off every 60 secs. (some ssh connections take a lot longer. 120+ in
some cases). The log should enable me to pinpoint any time
correlation to the long ssh connect occurrences (every 5 minutes? 1/2
past every hour? etc).
So here we are back to the script.. The script works as
expected, with one item of strangeness. I was expecting the log
messages to be printed in the order they complete. For example, if the
connection attempt at 12:01 took 75 seconds to return, and the
connection attempt at 12:02 to 5 seconds to return, I would expect the
12:02 message to appear first then the 12:01, but it doesn't. The
12:02 connection won't print until the 12:01 returns.
Here is my code:
use strict;
use Getopt::Std;
use Sys::Hostname;
use File::Basename;
use Net::SSH qw( sshopen2 );
use Time::HiRes qw( gettimeofday tv_interval );
$|++;
$SIG{CHLD} = 'IGNORE';
my %opts;
getopts('dr:', \%opts);
my $localhost = hostname();
my $r_host= $opts{'r'} ? $opts{'r'} : die need remote host -r
\n;
my $debug = $opts{'d'};
my $short_name = basename($0, .pl);
# --- set the counter to zero. We'll print the counter to the log for
easier sorting
# --- of data where the ssh connections take longer than a minute to
return.
my $ct = 0;
while (1) {
my $pid = fork();
if ($pid) {
# parent
} elsif ($pid == 0) {
# child
my $p = _initialize($ct);
waitpid($p, 0);
exit 0;
} else {
die couldnt fork: $!\n;
}
$ct++;
sleep 60;
}
# ---
# --- sub: initialize
# --- descr: for easier viewing of the code for the fork process.
# --- returns: nothing
# ---
sub _initialize{
my($count) = @_;
my $now= scalar localtime();
my $start = [gettimeofday()];
my $ret = connect_to_remote_host($r_host);
my $elapsed = tv_interval( $start );
if ($count 10){
$count = 0$count;
}
if ($count 99){
$count = 0$count;
}
my $msg = $count - [$now] $localhost to $r_host Elapsed time:
$elapsed ;
write_to_log($msg);
return;
}
# ---
# --- sub: connect_to_remote_host
# --- descr: uses ssh to connect to a remote host via ssh keys only.
# --- returns: nothing.
# ---
sub connect_to_remote_host {
my($host) = @_;
my $user = 'root';
my $cmd = uname -n;
my $out = ;
sshopen2($user\@$host, *READER, *WRITER, $cmd) || die ssh:
$!;
while (READER) {
chomp();
#print $_\n;
$out = $_;
}
close(READER);
close(WRITER);
return $out;
}
# ---
# --- sub: write_to_log
# --- descr: write messages to log file or print to stdout when in
debug
# --- returns: nothing
sub write_to_log{
my ($message) = @_;
my $log = /tmp/$short_name.log;
if ($debug){
print $message\n;
}
open L, $log or die Cannot open $log:$!\n;
print L $message\n;
close L;
}
Just wondering why the messages being printed to the console waits for
the previous pid (or pids) to complete before it's viewable.
FYI - I implemented the Counter thinking the messages weren't always
going to be in order and that I could always to a quick sort on the
counter to get the correct timeline.
Thanks,
Chad

Are you sure it's necessary to open and close the log file every

Couldn't you just open it one time in the parent process? Perhaps
that accounts for the variance in write order.

I don't think you can rely on the order of things happening
though in different processes (or threads). So I don't know that
it's really anything to be concerned about. If anything, I would
design the output so that order didn't matter. As you said, you
can always sort the output later if it helps to interpret it. I'm
only assuming that I understand what's happening though. ^_^

Hi Juan,
You might have GCC installed but do you have it configured?
Error: no compiler detected to compile 'lib/DateTime.c'. Aborting
Seems quite clear to me there is no C compiler found, you might want to
have
a look at your CPAN settings and see if your compiler is set there.
Normally
assuming you had the compiler installed before running CPAN setup it would
automatically detect the compiler. By the sound of it you might have
installed the compiler after running the CPAN setup in which case it will
simply have no compiler listed and will likely throw an error like this.
The other errors seems to stem from this problem so resolving that should
most likely fix the rest of the errors as well.
Regards,
Rob

Re: Installing CPAN Params::Validate and DateTime on Mac OS X 10.6.8
Doubt this would be the problem but I had to run as sudo to install CPAN
modules recently??? Otherwise, I would get a permissions issue, but it
would say No such file or directory.

Re: Installing CPAN Params::Validate and DateTime on Mac OS X 10.6.8
Nope, I've been running cpan under sudo. I'm going to try installing cmake
with brew and pointing to that vs make.
Maybe it will help. I'll already reinstalled perl using pacifist and no
luck. I also tried installing the modules on a new clean install and
nothing. I'm thinking the module may be broken and need an update.
Any advice on installing a fresh install of perl and cpan in a different
directory?
Flags etc...?

Re: Perl Fork and writing to stdout
sunckell wrote:
Hello Perl People
I was wondering if someone could enlighten me on an observation I
have been seeing..
A little Background info:
Where I work we have been seeing very slow ssh connections times
(it's not DNS. Maybe NIS, NFS, but definitely not DNS).
Anyways I wanted to write a script that would log the time it
takes to connect to a remote server via ssh and issue a command (uname
-n). The tricky part was that I wanted the remote connections to kick
off every 60 secs. (some ssh connections take a lot longer. 120+ in
some cases). The log should enable me to pinpoint any time
correlation to the long ssh connect occurrences (every 5 minutes? 1/2
past every hour? etc).
So here we are back to the script.. The script works as
expected, with one item of strangeness. I was expecting the log
messages to be printed in the order they complete. For example, if the
connection attempt at 12:01 took 75 seconds to return, and the
connection attempt at 12:02 to 5 seconds to return, I would expect the
12:02 message to appear first then the 12:01, but it doesn't. The
12:02 connection won't print until the 12:01 returns.
Here is my code:
use strict;
use Getopt::Std;
use Sys::Hostname;
use File::Basename;
use Net::SSH qw( sshopen2 );
use Time::HiRes qw( gettimeofday tv_interval );
$|++;
$SIG{CHLD} = 'IGNORE';
my %opts;
getopts('dr:', \%opts);
my $localhost = hostname();
my $r_host= $opts{'r'} ? $opts{'r'} : die need remote host-r
\n;
That is usually written as:
my $r_host= $opts{ r } or die need remote host-r\n;
my $debug = $opts{'d'};
my $short_name = basename($0, .pl);
# --- set the counter to zero. We'll print the counter to the log for
easier sorting
# --- of data where the ssh connections take longer than a minute to
return.
my $ct = 0;
while (1) {
my $pid = fork();
if ($pid) {
# parent
} elsif ($pid == 0) {
# child
my $p = _initialize($ct);
waitpid($p, 0);
exit 0;
} else {
die couldnt fork: $!\n;
}
That won't work correctly if fork returns undef and sets $! because
undef in numerical context is the same as 0.
$ perl -le'print undef is , undef == 0 ? : NOT , equal to 0'
undef is equal to 0
And without warnings enabled you won't catch this mistake.
See:
perldoc perlipc
For how to verify that fork() worked correctly.
$ct++;
sleep 60;
}
# ---
# --- sub: initialize
# --- descr: for easier viewing of the code for the fork process.
# --- returns: nothing
# ---
sub _initialize{
my($count) = @_;
my $now= scalar localtime();
my $now = forces scalar context on the right hand side of the
assignment so the use of scalar is redundant.
my $start = [gettimeofday()];
my $ret = connect_to_remote_host($r_host);
my $elapsed = tv_interval( $start );
if ($count 10){
$count = 0$count;
}
if ($count 99){
$count = 0$count;
}
That is usually performed with sprintf:
$count = sprintf '%03d', $_[ 0 ];
my $msg = $count - [$now] $localhost to $r_host Elapsed time:
$elapsed ;
write_to_log($msg);
return;
}
