rockymyx / aszip Goto Github PK

When making a zip, you choose between storing the crc, uncompressed size,
and compressed size either before the file data (in the local file header),
or after the file data (in the data descriptor).  If you store it in the
data desciptor, you have to set a bit flag indicating so.  The ASZip class
was setting the crc and sizes in both the local file header and the data
descriptor, but was not setting the bit flag.  This caused the java zip
implementation to fail because there were extra bytes after the file data.
 The change I had you put in just commented out the part of the class that
wrote the data descriptor.

For more info, here's the spec:

What steps will reproduce the problem?
1. Load a SWF file in an AIR application as a byteArray so it can be
included in every zip.
var _ur:URLRequest = new URLRequest( "assets/index.swf" );
var _ul:URLLoader = new URLLoader( _ur );
_ul.dataFormat = URLLoaderDataFormat.BINARY;
_ul.addEventListener( Event.COMPLETE, _onAssetSWFLoad, false, 0, true );
_ul.load( _ur );
2. Add the byteArray to a new ASZip using addFile. (This alters the length
of the byteArray, corrupting the file. It also doesn't reset the position
in the byteArray).
var _zipper:ASZip = new ASZip();
zipper.addFile( _swfFile, "index.swf" );
3. Repeat the process again, by creating a new ASZip and adding the same
byteArray using addFile. The SWF in the zipped file will be corrupted.

What is the expected output? What do you see instead?
It should not alter the source byteArray. Also (to a lesser degree) it
should reset the position in the byteArray to where it was before adding
the file.

What version of the product are you using? On what operating system?
I'm using version 0.2 of ASZip, Flex 3.0.0, Flash Player 9 and Windows XP.

Please provide any additional information below.
You can work around this by making a copy of your byteArray using the
readBytes method to make a copy.
var tempCopy:ByteArray = new ByteArray();
_swfFile.readBytes( tempCopy, 0, _swfFile.length );
_swfFile.position = 0;

Thanks for this framework, though. It is very easy to use!

What steps will reproduce the problem?

1. I'm creating a class to generate XLSX files for Excel 2007, these files
are a set of XLM files zipped with XLSX extension.

2. I zip all neccesary files with ASZIP to a file named test.xlsx, it's ok.

3. I try to open test.xlsx with Excel 2007 and it doesnt want to open it,
says there is a problem with the file.

4. To test what is happening i unzip test.xlsx to a folder and then i zip
all files again manually with winrar, using zip compression instead rar, i
name this file testwinrar.xlsx, then i can open it successfully with Excel
2007.

I've attached the test.xlsx and test2.xlsx files
- test.xlsx is created with ASZIP and CAN'T be opened in Excel 2007
- test2.xlsx is created with winrar based on test.xlsx unzipped files and
CAN be opened in Excel 2007

Could you test the problem?


I'm using Windows XP - Flex 3

Thanks in advance

What steps will reproduce the problem?
1. The create.php file sends back a .zip file of size 0 kb
2.
3.

What is the expected output? What do you see instead?

The actual zip file created from the raw post data should be returned back

What version of the product are you using? On what operating system?

0.2 - Windows

Please provide any additional information below.

The php should have this line
  echo $zip; 
instead of  
  echo $pdf;

What steps will reproduce the problem?
1. Running Flash Professional CS5.5 SWF file
2.
3.

What is the expected output? What do you see instead?
Expect AlivePDF to save what's visible on the stage as a PDF.  The PDF saves 
but is blank.

What version of the product are you using? On what operating system?
1.51 on Windows 7
