    <p>I'm simply trying to get a list of filenames given a path with wildcard.</p> <pre class="lang-perl prettyprint-override"><code>my $path = "/foo/bar/*/*.txt"; my @file_list = glob($path); foreach $current_file (@file_list) { print "\n- $current_file"; } </code></pre> <p>Mostly this works perfectly, but if there's a file greater than 2GB, somewhere in one of the /foo/bar/* subpaths, the glob returns an empty array without any error or warning.</p> <p>If I remove the file file or add a character/bracket sequence like this:</p> <pre class="lang-perl prettyprint-override"><code>my $path = "/foo/bar/*[0-9]/*.txt"; </code></pre> <p>or</p> <pre class="lang-perl prettyprint-override"><code>my $path = "/foo/bar/*1/*.txt"; </code></pre> <p>then the glob works again.</p> <p>UPDATE:</p> <p>Here's an example (for a matter of business policy I had to mask the pathname):</p> <pre><code>[root]/foo/bar # ls -lrt drwxr-xr-x 2 root system 256 Oct 11 2006 lost+found drwxr-xr-x 2 root system 256 Dec 27 2007 abc*** drwxr-xr-x 2 root system 256 Nov 12 15:32 cde*** -rw-r--r-- 1 root system 2734193149 Nov 15 05:07 archive1.tar.gz -rw-r--r-- 1 root system 6913743 Nov 16 05:05 archive2.tar.gz drwxr-xr-x 2 root system 256 Nov 16 10:00 fgh*** [root]/foo/bar # /home/user/test.pl [root]/foo/bar # </code></pre> <p>Removing the >2GB file (or globbing with "/foo/bar/[acf]<em>/</em>" istead of "/foo/bar/<em>/</em>")</p> <pre><code>[root]/foo/bar # ls -lrt drwxr-xr-x 2 root system 256 Oct 11 2006 lost+found drwxr-xr-x 2 root system 256 Dec 27 2007 abc*** drwxr-xr-x 2 root system 256 Nov 12 15:32 cde*** -rw-r--r-- 1 root system 6913743 Nov 16 05:05 archive2.tar.gz drwxr-xr-x 2 root system 256 Nov 16 10:00 fgh*** [root]/foo/bar # /home/user/test.pl - /foo/bar/abc***/heapdump.phd.gz - /foo/bar/cde***/javacore.txt.gz - /foo/bar/fgh***/stuff.txt [root]/foo/bar # </code></pre> <p>Any suggestion?</p> <p>I'm working with: Perl 5.8.8 Aix 5.3 The filesystem is a local jfs.</p>

    1. COIs this the actual, entire program that gave the problem? The only reason I'm asking is that an earlier `glob` could affect what a later `glob` returns.

    2. COThe problem came out on a more complex code, but the issue is perfectly replicated by this snipplet.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
