Peter, What we have noticed is; perl v5.8.0 $FindBin::Bin is returning /usr/local/bin and perl v5.8.5 $FindBin::Bin is returning /usr/local/bin/ The next / at the end of bin.

The server with Perl v5.8.5 produces different results from the pop (line 458 below) and I'm not sure why. Can you help answer my question? If Cpop() is returning different results, then the array it is pop'ping off of is likely getting populated in a different order, or with different results. From what you've included, though, its hard to say. How are the results different in 5.8.5 from 5.8.0?

Re: [perl #36967] Pod/Perldoc.pm bug with -m switch
On Mon, 22 Aug 2005 10:41:15 -0600 Jim Cromie [EMAIL PROTECTED] wrote: Hi Jim, From the point of view of Pod/Perldoc.pm there's no differences between .pod or .pm files or, more in general, between a generic file or Perl module. For example, I can view the source of 'media.types' file shipped with LPW: % perldoc -m LWP::media.types The bug (or 'strange' behaviour if you prefere) I've noted is that Pod/Perldoc.pm adds .pod extension to perldoc argument only under certain (and, in this case, inconsistent) circumstances and still I don't understand why. I think the biggest reason is if you have both Foo.pm and Foo.pod your previous patch (I think) will prefer Foo.pod, making Foo.pm unavailable. I agree with this, but one can check also for Foo.pod after checking Foo.pm, not disabling that at all. Currently, if Foo.pm isn't found, there is no chanche to check also Foo.pod again (in the same path). Attached patch maintains precedence of .pm over .pod (in order to looking at the code first with -m switch) but also check for .pod suffix then. this may also be reason for looking in pods/* In general, putting pure pod under pod/pods dedicated directory is a good thing (and IMHO it should be the rule) but is poorly documented and/or suggested.

Hi, i've found a small code that triggers a segfault on the
following perl versions :

5.8.7 (debian testing package)

5.9.1 (compiled on my linux debian testing i386, gcc-4.0.1)
unaffected versions :

Priority is low, since this code is incorrect, but it might help
resolving other issues.
the segfault does not appear when not using 'strict'.
note that no code is executed since it's in a sub that is never
called at runtime.

Also with just: perl -I../lib -MO=Concise,BEGIN,-exec -e0
As instructed, Concise is dumping out the BEGIN blocks, even some of
the ones in Concise.pm itself, specifically the two lines:
no strict 'refs';
and
no warnings 'qw'; # Possible attempt to put comments...; use #7
The method_named ops are the unimport() method calls that no generates.
It seems that the SV that holds the method name has an integer value also
(perhaps related to sharing?) and Concise is showing that in preference
to the string value.
The following (untested) would be an unobtrusive way to fix this in
this one case, though it might be better for concise_sv to dump both
the string and numeric values when both are present.

This way it's possible to return Perl's internal data structures if the piece of memory got re-used and possibly also cause Perl to crash if that piece of memory has been returned to the operating system. Here's a simple example to confirm the bug (tested under Windows NT / ActivePerl 5.8.7 and Linux 2.4 / Perl 5.8.0): use strict; use warnings; my $s = abcd; $s =~ /(..)(..)/g; $s = $1; $s = $2; print $s\n; The statement $s = $1 causes Perl to re-use the string abcd for storing the first half (ab) and add a terminating zero. $2 still points to the original second half but the character c got overwritten neanwhile. So if the bug is present you will get c or just c printed out instead of the expected cd.

Hi, i've found a small code that triggers a segfault on the

unaffected versions :
version 5.005_03 built for sun4-solaris
Priority is low, since this code is incorrect, but it might help
resolving other issues.
the segfault does not appear when not using 'strict'.
note that no code is executed since it's in a sub that is never
called at runtime.
-- CODE BEGINS HERE --
#!/usr/bin/perl
use strict;
sub s { open $X, my $Y, r; }
-- CODE ENDS HERE --
This appears to have been fixed in bleadperl. I'm not sure, though,
what the exact fix was. Using perl-current, I get:
./perl -Mstrict -wle'sub s { open $X, my $Y, r; }'
Global symbol $X requires explicit package name at -e line 1.
Execution of -e aborted due to compilation errors.
In the 5.8 releases, the coredump occurs in Perl_ck_open.

A sniff of the blame log shows that patch 24523 did a little consting

Does consting stuff like this get rolled into the various maints as a
matter of course?

[perl #37039] perlref documentation about optional - is too vague
# New Ticket Created by [EMAIL PROTECTED]
# Please include the string: [perl #37039]
# in the subject line of all future correspondence about this issue.
# URL: https://rt.perl.org/rt3/Ticket/Display.html?id=37039
This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.4.
-
[Please enter your report here]
In 'perlref', item #3 of 'Using References' says
One more thing here. The arrow is optional between brackets sub-
scripts, so you can shrink the above down to
$array[$x]{foo}[0] = January;
This led me to believe I could write:
sub foo { ...; return @data }
my $x = (foo())[0][1];
which would have the same effect as
my @return = foo();
my $x = $return[0][1];
However, it's a syntax error. This can be fixed with an arrow:
my $x = (foo())[0]-[1];
The problem is that (foo())[0] is NOT analogous to $array[$x]; one is a
list slice, the other is a single element from an array. But the
documentation does not distinguish when it says optional between brackets
subscripts [sic].
I think the language there should be polished a bit.

This seems to go a bit deeper. My current bleadperl works fine on

This way it's possible to return Perl's internal data structures if the piece of memory got re-used and possibly also cause Perl to crash if that piece of memory has been returned to the operating system. Here's a simple example to confirm the bug (tested under Windows NT / ActivePerl 5.8.7 and Linux 2.4 / Perl 5.8.0): use strict; use warnings; my $s = abcd; $s =~ /(..)(..)/g; $s = $1; $s = $2; print $s\n; The statement $s = $1 causes Perl to re-use the string abcd for storing the first half (ab) and add a terminating zero. $2 still points to the original second half but the character c got overwritten neanwhile. So if the bug is present you will get c or just c printed out instead of the expected cd. I can confirm this behaviour is in 5.8.6 and 5.6.1 on Win32. yves -- perl -Mre=debug -e /just|another|perl|hacker/
Re: Fw: Re: [PATCH] Re: Transliteration operator(tr//)on EBCDIC platform
Hi Sadahiro
The patch has resolved four tests that were failing previously but one
more test is stilling failing(which was failing even before applying the
patch).
Here is the test case
($a = v300.196.172.302.197.172) =~ tr/\x{12c}-\x{130}/\xc0-\xc4/;
is($a, v192.196.172.194.197.172, 'UTF range');
# got 'DÐDEÐ'
# expected '{DÐBEÐ'
Can you suggest some pointers towards fixing this?

According to the above statement in perlebcdic.pod,
s/[\x89-\x91]/X/g must substitute \x8e with X.
But it doesn't concern whether tr/\x89-\x91/X/ would substitute \x8e
with X or not, since tr/// does not use brackets, [ ].
Though I think ranges in [ ] and ranges in tr/// should coincide
and agree that tr/\x89-\x91/X/ should substitute \x8e with X,
that is just my opinion.
I don't know whether it is true and correct.
Is there some way we can confirm if this is correct (and expected
behaviour)
since there isnt any explicit documentation for the tr operator ?
Since t/op/tr.t already has a test case (cf. Change 9038)
which Sastry previously pointed out its failing on EBCDIC Platform,
I assume that at least the then pumpking thought it to be correct.
By the way, when you say If I specify [\x89-\x91], does it
mean s/[\x89-\x91]/X/g or tr/\x89-\x91/X/ ? I'm confused.
We mean tr/\x89-\x91/X/.
We are first informed by you that gapped characters are not
substituted with X by tr/\x89-\x91/X/.
And you said s/[\x89-\x91]/X/g substituted all the characters
including gapped characters with X, hadn't you?
Yes.
If so, I assume your [\x89-\x91] which doesn't matching any of
the gapped characters to be tr/\x89-\x91/X/.
That's correct. We mean tr/\x89-\x91/X/.
The following is a part of the current core tests from op/pat.t.
I believe they should be passed.
Yes all the following tests pass. I think the following tests are in
the context of the
s/[]/X/ operator and hence pass.
Thanks,
Rajarshi.
OK. To me, it is confirmed that s/[]/X/ is fine and tr/// has a problem.
Since I don't have any EBCDIC machine, I can't ensure the following
patch will really makes sense.

advice needed for lib/File/Copy.t dates not preserved on VMS
Test 20 of lib/File/Copy.t is failing on VMS because the copied file has not inherited the creation date from the original file. This is consistent with the way that the COPY command works from the DCL command shell on VMS. While I can change VMS to follow this behavior, I am concerned that it could break things. Also, nothing in the documentation at http://perldoc.perl.org/File/Copy.html indicates that the new file would be created with the dates associated with the new file. So I am curious why this test is even being done. My copy of LINUX IN A NUTSHELL also indicates that having the destination file get the original file's attributes is not the default behavior of the cp command. -John [EMAIL PROTECTED] Personal Opinion Only

And even though the test description says mtime preserved by copy(), it's not testing copy() but rather move(). If you simply rename a file, it does seem that mtime ought to stay the same.
