Double-extension of downloaded file saved at ntfs or vfat

[Arseny Solokha]

Binary package hint: firefox

Ubuntu 7.04; Firefox 2.0.0.4

When I click every link for downloading a file and choose "Download" (sorry, I work with Russian locale so I can't say how does this button/radio named), downloading begins. So, downloaded file has double extension. For example, foo.bar.bar. This name is also displaying on Download Manager. File contents doesn't broken, all works.

Steps:
1. Click to "Download" button
2. Enjoy _broken_ name in Download Manager
2`. Enjoy _broken_ name on the file system

Thank Arseny for your report,

Would you please reproduce the issue with an example we might be able to test here (i.e. an url) and describe it step by step. Since you are using Russian locale, please run firefox from a terminal as:

LANGUAGE=C firefox -safe-mode

Thank you in advance

Hello.

Thank you for your answer.

Steps again:
1. $LANGUAGE=C firefox -safe-mode http://packages.ubuntu.com
2. "Continue Safe mode" button-click
3. ***then I found link to download 'firefox' package for i386***;
goto page http://packages.ubuntu.com/cgi-bin/download.pl?arch=i386&file=pool%2Fmain%2Ff%2Ffirefox%2Ffirefox_2.0.0.4%2B1-0ubuntu1_i386.deb&md5sum=1dc5977f11f4edee93acd533bf534a11&arch=i386&type=security
4. You can see a link with text "security.ubuntu.com/ubuntu"; click it. Dialog with text "You have chosen to open firefox_2.0.0.4+1-0ubuntu1_i386.deb" will appear.
5. Chose "Save to Disk" and click OK.
6. You'll see "firefox_2.0.0.4+1-0ubuntu1_i386.deb.deb" in the "Downloads" window.

I hope it'll be useful.
Best regards,
Arseny.

P.S. File with name "firefox_2.0.0.4+1-0ubuntu1_i386.deb.deb" will be also saved to file system.

Thank you Arseny,

I've followed your steps and it works for me rightly.

Adding mt-needtester tag waiting for someone that is able to confirm this behavior.

[Arseny Solokha (asolokha-deactivatedaccount)]

OK, Hilario.

I've built and tested FF2.0.0.4 on Gentoo and it also works properly. But patchset was automatically applyed before building.
Firstly I thougth that problem can be in Ubunut's patches (or maybe Gentoo's patchset fix this problem), but then I decided to test Firefox behavour on other file systems. I could test it with ext3, xfs, ntfs and fat32 partitions.
Results:
1. Problem NEVER occures with xfs
2. Problem occures FROM TIME TO TIME with ext3 and fat32 (mostly seldom)
3. Probles ALWAYS occures with ntfs (driver is ntfs-3g of previous version. I'm sorry I forget it's number...)

So, (1) You shouldn't search tester and (2) the problem is mostly related to ntfs-3g.
I'm sorry for my stupidly questions.

Best regards,
Arseny.

P.S. On machine with Gentoo I have only ext3 filesystem. And problem never occures there.

[Hilario J. Montoliu (hjmf) (hmontoliu)]

Thanks Arseny for your complete report,

I've done some test here too, and I can reproduce the described issue when I try to download to my ntfs-3g partition.

It doesn't happen when I test it at vfat, reiserfs or ext3.

Marking as confirmed.

[Hilario J. Montoliu (hjmf) (hmontoliu)]

hmm, done some more tests, and it is reproducible at vfat too.

If the extension is .exe then firefox saves it as .exe.bin

Looking upstream as I remember having seen this before.

[Hilario J. Montoliu (hjmf) (hmontoliu)]

Maybe we should merge together bug 113070 and bug 120951, or wait to see if upstream duplicates bugzilla #336113 with #270159

Way, described at
https://bugzilla.mozilla.org/show_bug.cgi?id=270159
and at
https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/105474
to change mount options from umask=000 to dmask=000,fmask=111 is seems to work. Thank you for this links.

But is this way legitimate? Is this "bug" or "feature"?

[Arseny Solokha (asolokha-deactivatedaccount)]

As far as I understood my bug appears only with Windows executable files with some users. But I have this bug with _every_ file which I save to ntfs partition mounted with ntfs-3g driver.
Maybe shall somebody test Firefox behavour with other ntfs drivers? Or problem is contained in mount options?
