Hi all,
The following code is running on a high traffic site:
open(file, "$mailclicks"); flock(file, 2); @recs = <file>; flock(file,
+ 8); close(file);
$i = 0;
foreach $rec (@recs) {
$rec =~ s/\n//g; ($id,$description,$need,$received) = split(/::/,$
+rec);
if ($id eq $formdata{'id'}) { $received++; $recs[$i] = "$id\::
+$description\::$need\::$received"; }
$i++;
}
open(file, ">$mailclicks"); flock(file, 2);
foreach $r (@recs) { print file "$r\n" unless ($r eq "" || $r eq "
+\n"); }
flock(file, 8); close(file);
This increments a tracking counter for use by another script.
The problem is that the data file goes blank randomly. Other scripts access the file but I have isolated it to this snippet.
I haven't been able to find a pattern or reproduce the problem myself. It generally takes 100 or so users before it happens. No corruption of the file along the way.
I'm hoping this is a common problem in perl?
Thanks much,
Ian

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).
