Hello all.
I am trying to do the following:
I have a shared hash, namely %hash1
I initiate a lock. The I call for a function on a particular key, and assign the function value to the key. Is the lock still on? I could not find an answer to it, and the documentation I have found on perldoc does not cover that angle.
See code:
use strict ;
use threads ;
use threads::shared ;
my %hash1 =(1,2, 3,4) ;
{
lock (%hash1) ;
$hash1{1} = foo ($hash1{1});
$hash1{3} = foo ($hash1{3})
}
My question is: Is the advisory lock active when $hash{3} is accessed and assigned, or is calling foo removes the lock (because of use strict and the scoping limitation? )Trying to test it may be tricky, and I am not sure if I know how to cover most angles. Using foo to lock the variable is useless, and passing it a reference to the hash, and then locking, may cause deadlocks.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
