Change 23895 by [EMAIL PROTECTED] on 2005/01/28 20:28:38
(Just the tests from)
Integrate:
[ 22663]
Make the ! suffix handle n/N/v/V as signed integers
within pack templates.
[ 22734]
Subject: [PATCH for testing/review] byte-order modifiers for (un)pack
templates
From: Marcus Holland-Moritz <[EMAIL PROTECTED]>
Date: Wed, 21 Apr 2004 21:09:20 +0200
Message-Id: <[EMAIL PROTECTED]>
[ 22780]
Add byte-order group modifiers to (un)pack templates.
Follow-up on: #22734, #22745, #22753, #22754.
Subject: Group modifiers in (un)pack templates
From: Marcus Holland-Moritz <[EMAIL PROTECTED]>
Date: Mon, 3 May 2004 20:14:41 +0200
Message-Id: <[EMAIL PROTECTED]>
[ 23850]
Name another pack test
[ 23884]
Make the tests for the endianness modifiers < and >, and the
signnedness modifier ! conditional on perl version. Surprisingly
little change needed.
[ 23886]
Check that the warning behaviour on the modifiers !, < and > is as we
expect it for this perl.
[ 23888]
Oops. Was forgetting to test n! N! v! V! in pack
