InstallApacheFlex - Optional components
I am working on the optional components downloads for the InstallApacheFlex
AIR app. For BlazeDS and the FontSwf utility, I am having to download the
entire Adobe Flex 4.6 SDK (this is what the ant script is doing) Is there
any chance that these two components are available as individual
downloads? The Adobe Flex 4.6 SDK is 300+ MB and would add quite a bit of
time to the installation process.
Thanks,
Om

I think the text that is in downloads.xml is sufficient. If you want to
provide a link to the Adobe Flex 4.6 eula, I think it is here [1].

Downloads.xml points to http://www.adobe.com/products/eula/third_party/ for
Third-party Legal Notices. Searching through that that page, I dont see
anything for Adobe 4.6. I see notices for Flex 2 through 4.5.
This seems to be the most relevant document:
http://www.adobe.com/products/eula/third_party/pdfs/flex4_5_sdk_opensource_legal_notices.pdf
Is showing this license sufficient?

I dont like this approach because it will cause issues with FB 4.7
onwards. And the approach wont scale for people using other IDEs. I would
rather not assume anything being installed on the computer.

If I can directly download just the jars from this location, that would be
perfect. I think the license dialog will work fine. I will put up a new
build of the app soon; you can take a look at me know.

In fact, if you assume these folks already have Flash Builder 4.6 installed,
then you can pretty much know where to get these files from within the Flash
Builder install.
I believe we chose to download the whole zip because it was already
protected by a licensing dialog (more or less). You might be able to get
these files from [1]. I think what is most critical is that the license
dialog is right.

Hi,
There a good chance that anyone install the SDK has the 4.6 SDK already - perhaps check a couple of likely locations and copy from there if possible? (ie standard FB instal directory etc)
If you can't find it add extra optional browse to 4.6 SDK in box at first step with tool tip explaining why it's needed.
Thanks,
Justin

Yup, my bad. Pretty big memory leaks because I am not cleaning things up
properly . I have added a few checks since, but I will add your
suggestions as well. Thanks for catching that.
BTW, I am sure there are other similar issues with the codebase, it would
do good to the codebase if it gets more eyballs :-)
Thanks,
Om

Hey Om,
I just had a quick look at the code and I see that for each call to: var
fzip:Zip = new Zip();
and subsequently adding event listeners, there isn't any clean up done.
Clean up, as in an explicit call to fzip.close() and removal of *all* event
listeners (there's 3 added and only 2 removed).
I'm guessing adding this to the code will make sure that a Zip instance
will be properly garbage collected
after its used, thus keeping the memory from ballooning.
So this method should at the very least look like this:
private function onUnzipComplete(event:Event):void
{
var fzip:Zip = event.target as Zip;
* fzip.close();*
fzip.removeEventListener(ZipEvent.FILE_LOADED, onFileLoaded);
fzip.removeEventListener(Event.COMPLETE, onUnzipComplete);
}
The dynamic Event.COMPLETE listener (unzipCompleteFunction) might be added
as a weak listener I guess.
cheers,
Roland

Actually, the problem is even worse than I thought.
Apache Flex Bin zip file = ~65 MB
Adobe Flex Bin zip file = ~336 MB
Since we are unzipping the files in actionscript, ADL's memory footprint is
ballooning up to more than 1+ GB. This is causing the unzipping to crash
with a "Error #1000: The system is out of memory." error.
Even though my computer has 8 Gigs of RAM, ADL has an limit of around 1GB
per app. So, this is expected behavior.
I really wish we dint have to download the Adobe Flex 4.6 zip file at all.
The other option is to ship 7-Zip along with the app and use it instead of
FZip. I am not sure if memory used by a NativeProcess counts towards the
ADL memory limit.
Any other ideas?
Thanks,
Om
