| 'Illegal Seek' - from Archive::Zip? |
|
I am generating an auto-extracting windows zip using Archive::Zip on Solaris. The downloaded files work fine but an 'Illegal Seek' is generated each time and I'm trying to clean up the code. Here's what I believe to be the offending code:
-------------------------------
sub writeZipFusionFile {
my ( $builder, @fileobjects ) = @_;
my $zip = Archive::Zip->new();
my $ztempfile = "$configdir$sessionId.zip";
my $zh = new IO::File($ztempfile, 'w') or die "can't create IO::File object for $ztempfile : $!";
my $memberFile;
if ( $builder ){
$memberFile = $zip->addFile("$setup_path","setup.exe");
$memberFile->desiredCompressionLevel(6);
my $time = time();
my $port = $ENV{REMOTE_PORT};
my $config_file = $configdir . $time . $port . "config.txt";
open(CONFIG,">$config_file") or warn("Can't open config file $config_file") && die_gracefu
+lly;
print CONFIG "filename::sb_fullpres.ppt\r\n";
print CONFIG "beginfiles\r\n";
foreach my $file( @fileobjects ){
my $ppt;
my $location = $presodir . "/" . $file->{location};
eval { $ppt = getPPTFromDir( $location );};
die_gracefully && warn($@) if ($@);
print CONFIG "$file->{file_name}\r\n";
warn("user $user adding file $file->{file_id}");
$memberFile = $zip->addFile($ppt,$file->{file_name}) ||
warn("$user Can't add file $file->{file_id}");
$memberFile->desiredCompressionLevel(6) ||
warn("$user Can't set compression for $file->{file_id}");
push(@file_ids,$file->{file_id});
}
print CONFIG "endfiles\r\n";
close CONFIG;
warn("adding stitcher config file : $config_file");
$memberFile = $zip->addFile("$config_file","config.txt") ||
warn("$user can't add stitcher config file");
$memberFile->desiredCompressionLevel(6);
warn("adding zipfusion config file");
$memberFile = $zip->addFile('./builder.zfc',"\[SFX\]Config.zfc") ||
warn("$user can't add zipfusion config file : $!");
#$memberFile = $zip->addFile($logo,"\[SFX\]logo.wmf") ||
#warn("$user can't add zipfusion logo file : $!");
my $result = $zip->writeToFileHandle($zh);
die_gracefully( "can't write zip to file $zh: $result" ) unless ($result == 0);
unlink $config_file;
} else {
foreach my $file( @fileobjects ){
my $ppt;
my $location = $presodir . "/" . $file->{location};
eval { $ppt = getPPTFromDir( $location );};
die_gracefully($@) if ($@);
warn("user $user adding file $file->{file_id}");
$memberFile = $zip->addFile($ppt,$file->{file_name}) ||
warn("$user Can't add file $file->{file_id}");
$memberFile->desiredCompressionLevel(6) ||
warn("$user Can't set compression for $file->{file_id}");
push(@file_ids,$file->{file_id});
}
warn "added lib file to zip. zip members : ", $zip->memberNames();
$memberFile = $zip->addFile('./library.zfc',"\[SFX\]Config.zfc") ||
warn("$user can't add zipfusion config file");
my $result = $zip->writeToFileHandle($zh);
die_gracefully( "can't write zip to file $zh: $result" ) unless ($result == 0);
warn "added zipfusion config to zip. zip members : ", $zip->memberNames();
}
undef $zh;
my $xtempfile = "$configdir$sessionId.exe";
open EXE,">$xtempfile" or die("Can't open $xtempfile for writing : $!");
open STUB,"<zf" or die("Can't open zipfusion stub for reading : $!");
foreach(<STUB>){
print EXE;
}
open ZIPTEMP, "<$ztempfile" or die("Can't open $ztempfile for reading : $!");
foreach(<ZIPTEMP>){
print EXE;
}
close ZIPTEMP;
unlink $ztempfile;
close EXE;
warn ("zip -A results : ", `/usr/local/bin/zip -A $xtempfile`);
return $xtempfile;
}
-------------------------------
Any suggestions?
