Subject: 2.6.29 broke the bridge!
Message-Id: <49d4b9a6$0$194$e4fe514c@news.xs4all.nl>
Hi,
Today I upgraded my 2.6.28(.2) kernel tot 2.6.29. I use KVM to run
several guests. All of them are connected via a tap interface to a bridge.
To set everything up I've created some simple bash scripts, no change
has been made in them during the update.
After booting 2.6.29 networking to the guests stopped partialy. Packets
generated by the guests got lost somewhere. Tcpdumping on the bridge
they were seen, but on the received external hosts the packets were
nowhere to be seen.
Reverting back to the old kernel, everything worked fine as usual.
Because the only thing done was booting a new kernel, I suspect the
cause must be in here somewhere. For compiling the 2.6.29 I used 'zcat
/proc/config.gz' > .config in the source directory and ran 'make
menuconfig' once, without making changes.
What has changed in 2.6.29 causing the bridges to fail?
Regards,
Frank

Understand that this is client driven. The diagnoses come from the
client's client, and the client's client requires that the diagnoses
be retained as part of the data. To me as the builder of the app, the
diagnoses are irrelevant. To my client, the customer, they are only
marginally useful. To the client's client, they form an essential part
of a patient record.
Anyway, I've made the decision. I'm concating all the diagnosis data
into a database column of type text, and I'm not even going to worry
about a nice display. The only concession I'm going to make is to
provide a key word search function, which I can easily do with like:
$search = <>;
$sth->prepare("select * from account with diagnosis like %?%"); $sth-
>execute($search);

I don't think that the above SQL is syntactically correct.
Anyway, with Perl 5.10 you could, for example, do the following:
use strict;
use warnings;
use 5.010;
...
my $search =3D <>;
$sth =3D $dbh->prepare("SELECT diagnosis FROM account");
$sth->execute();
while (my ($diag) =3D $sth->fetchrow_array) {
if ($search ~~ [split /\|/, $diag]) {
say "Found $diag";
}
}

What do you mean, O(N log N)? Sorting is O(1), it's an OS function!

Subject: How to find directory of package residence from within package?
Message-Id: <c6eb0a48-79ba-4362-bfe7-735713e3d5eb@x31g2000prc.googlegroups.com>
Hi, in case of a package, I need to populate the 'pwd' key of $self
with the directory of the same package's residence. I used Cwd but it
doesn't work in all cases. For example:
/home/kris/1.pl (WIP is an immediate subdirectory of this script's
directory)
==========================================================
use warnings;
use strict;
use WIP::Test;
my $obj = WIP::Test->new();
print $obj->pwd,"\n";
Package WIP/Test.pm
========
package WIP::Test;
use warnings;
use Cwd qw(getcwd);
sub new
{
my $pkg = shift;
my $classname = ref $pkg || $pkg;
my $self = {};
$self->{pwd} = getcwd();
bless $self, $classname;
return $self;
}
sub pwd
{
my $self = shift;
return $self->{pwd};
}
1;
In this case, if I run the 1.pl script from /home/kris, it gives /home/
kris rather than /home/kris/WIP (which is what I want). I want the
module to "remember" where it is located (without hard-coding it since
the module could be moved around in a flexible install)
Do you know how it can done easily using any special variable or
technique? I've thought about one way (which doesn't sound very
efficient to myself):
package WIP::Test;
use warnings;
use Cwd qw(getcwd);
my $pwd = undef;
use File::Find;
find(
{
wanted => sub {
my $pkg = __PACKAGE__;
$pkg =~ s|::|/|g;
$pkg = $pkg . ".pm";
if (/$pkg$/) {
$pwd = abs_path($File::Find::dir);
}
},
no_chdir => 1,
},
@INC
);
sub new
{
...
...
...
Regards...

Er, read last line above as:

One way may be to make use of the %INC hash.
( my $pwd = $INC{'WIP/Test.pm'} ) =~ s/Test\.pm//;

Sample pattern:

<Style:DK>Antikviteter
All on seperate lines. The file is generated on a Windows PC (\r\n),
my file needs to end up as a UNIX-file on Mac OS X
The first file had accidently been opened on a Mac, hence the \r end
of line.
I hope this clears things a bit up.
The file is being converted from 1252 to Macroman prior being run
through script (/usr/bin/iconv -f WINDOWS-1252 -t MACROMAN). However I
am considdering using 'Text::Iconv' instead.

That is NOT the pattern to be matched!
The pattern to be matched is:
&00([^\r]+)\r\n
Those are (meant to be) the strings that the pattern is to be matched against.
The reason that none of those strings match the pattern is because
none of those strings contain a carriage return, and the pattern requires
a carriage return.
A hex dump, such as from xxd, shows that there are no carriage returns
in that data. Each lines ends with a caret (ASCII 0x5e), an upper
case "M" (ASCII 0x4d) and a linefeed (ASCII 0x0a):
0000000: 2630 3041 6e74 6971 7565 735e 4d0a 2630 &00Antiques^M.&0
^^ ^^^^

0000030: 6974 3c30 7830 3045 393e 735e 4d0a 2630 it<0x00E9>s^M.&0
^^ ^^^^
If you cannot figure out how to post data with the line endings that
are actually in your data, then write the data in Real Perl Code.
(that sounds familiar...)
instead of
while ( <FILE> ) {
put the data into an array and loop over the array:
my @lines = ( "&00Antiques\r\n", "&00Antiquit<0x00E4>ten\r\n", ...
foreach ( @lines ) {
> The file is generated on a Windows PC (\r\n),
> my file needs to end up as a UNIX-file on Mac OS X
Then all you need to do is delete all of the carriage returns before
matching:
tr/\r//d;
and change the pattern to not require carriage returns.
> The first file had accidently been opened on a Mac, hence the \r end
> of line.
That explains it then.
On Linux/OS X the input operator, <>, reads until it finds a newline.
Since there were no newlines, a single read gets the entire file in one go.

Message-Id: <a8e2df11-4214-414a-86af-58d04f6ff368@j8g2000yql.googlegroups.com>
Hi,
i posted this to the perl.beginners group yesterday morning but it
seems it got lost...
Anyway.
I have started using Perl and i quite like it!
As i come from the Windows world, i started looking about my GUI
options and decided to use wxWidgets.
So, i know that there is wxGlade that produce Perl code but i found
some other very nice tools (wxFormDesigner, DialogBlocks and some
other) too that they seem to be better than wxGlade (more controls,
more stable) only that they generate XRC code.
My question is:
Can i use this XRC generated code from (wx)Perl easily so to display
the GUI ?
And in general, is it better to use tools (like wxGlade) that generate
directly Perl code or using some more advanced ones but produce XRC ?
What is the advantages of each option ?
Thanks a lot for any help on this,
K.K.

First off, wxWidgets is an excellent toolkit.
Using wxGlade is the obvious choice for someone
with a Windows background.
It protects you from things not commonly done on
Windows like checking return values of calls, looking at
error messages, and reading documentation.
Some folks on this group might suggest that you just
use the Wx perl module and code your UI from the
ground up. Nonsense! You would actually have to
learn how the various subsystems work and interact.
Then when you have a problem, you would be the one stuck
fixing it instead of just being able to throw your
hands up and walk away.

Hey, thanks for the reply!
I plan to use wxGlade (or some sort of form designer, i would never
code the UI by hand) but what are the differences by using Perl
generated code and XRC one ?

Perl is a great tool to use for a few things, like database stuff,
data manipulation, and user interfaces using a browser including web
sites. However, it's not the best tool for everything in the world,
and you will do well to match the tool to the task at hand.

Most of the stuff I do is Windows based, as I work in a 100% Microsoft
shop (except for me.) Once or twice I have tried to build a GUI app
with Perl, but Java is much better for this, or .NET. All of the GUI
apps I write are webified, and the users interact with the app using a
browser. This really is the way of the future (IMO) and (IMO) you
would do well to learn how to webify your own applications.

HTML, CSS, and Javascript is easy enough to write by hand, using
Notepad, or vi (gVim for Windows). I don't know what you are doing,
and I certainly wouldn't suggest that these kinds of tools don't have
their place, but for the simple things I do, I can use vi or a similar
tool faster and more accurately than a point and click tool, like VS
(for example). Mostly, you can build your own HTMLized components, put
them in a module, and call them when you need them.
