compressing a file of ~100MB gives incomplete zip file

[jokester]

Got an incomplete zip file of 100 bytes, when I tried to compress a ~100MB xml file via temporary storage in RAM.

It seems only zip header(PK~) / filename are there, not compressed date itself.

Didn't observe exception in browser console or demo page.

I can reproduce it by:

1. open http://gildas-lormeau.github.com/zip.js/demos/demo1.html  , with chromium 25.0.1364.172 (187217)
2. add the 100MB file when RAM is chosen for temp storage
3. wait till finish, and click "download".

By the way, a few tests

• For ~50MB file, temporary storage at RAM still works
• For ~500MB file, temporary storage at HDD still works

Any idea about the real threshold?

I was able to reproduce your issue with Chrome 25.0.1364.172 and the latest stable version 26.0.1410.43 m. From my point of view it's a regression from Chrome.

If I put a breakpoint at line 71 in demo1.js, I see that the blob object seems ok : its length is about 100 MB in my test, but the blob URL points to a corrupted Blob. In Chromium 27.0.1454.0 (190683), I wasn't able to reproduce this issue so it may have already been fixed. I think I will however open an issue on crbug.com.
