-_ key does not work in firefox with 2.10 (and newer?) #202

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. use firefox to access shellinabox and try to use the -_ key (US keyboard), 
nothing happens. The - key on the keypad does work

I can also reproduce this problem on the example shell on the project home page

I did not have this problem with chrome, but with it I was getting a large 
memory leak.

Original issue reported on code.google.com by david.eu...@gmail.com on 31 Aug 2012 at 2:04

GoogleCodeExporter commented 9 years ago 
This is happening to me also, on a UK keyboard.

The - (minus) and _ (underscore, shift-minus) keystrokes are not registering 
under Firefox 15 on MS Windows 7 SP1. However these keystrokes do work under 
Internet Explorer 8 on Win7SP1.

This *only* applies to the minus key on the main alpha keypad. The minus key on 
the numeric keypad seems to work okay.

A workaround is to use the minus key on the numeric keypad. However this 
workaround does not work for underscore. To enter an underscore, I have to copy 
it into the clipboard from another program (e.g. Notepad) and then paste it 
into the Shellinabox tab in Firefox.

This bug appears to be limited to Firefox. However I can input a minus and 
underscore correctly on any other web page that I load on Firefox (e.g. to 
report this bug. This bug comment was submitted using Firefox 15, and I can 
type minus or underscore to my heart's content ----____ but in the very same 
browser instance, on another tab, I cannot enter a minus or underscore into 
Shellinabox.

ShellInABox version 2.10 (revision 186)
Firefox 15

This issue is has suddenly made Shellinabox unusable for me (I write a lot of 
shell commands which require minus to pass parameters), which is very 
frustrating. I would be most grateful for the developers to investigate 
urgently.

I strongly suspect this is due to a recent change in the Firefox/Gecko virtual 
key codes which affects Firefox 15.

Quote from https://github.com/openlayers/openlayers/issues/605
> Firefox 15 is likely to break some of the KeyboardDefaults funtionality.
> Currently in FF 15b1, the minus (-) key does not get captured by the
> KeyboardDefaults Control anymore.
> 
> Any other key seem to be fine so far, but according to the following docs,
> the plus (+) key will change as well:
> https://developer.mozilla.org/en/DOM/KeyboardEvent#Virtual_key_codes
> 
> New minus code (-): 173
> New plus code (+): 171
> (both are for the 'normal' keyboard. The keypad codes don't seem to have
> changed (yet))
> 
> None of the OpenLayers.Event.KEY_* are affected atm AFAICT.

Reverting to Firefox 14 and preventing automatic updates (Tools - Options - 
Advanced - Update) works around this problem.

However it is not a good idea to use an outdated browser in the long term.

Firefox 14 can be downloaded from:

The following keys are broken too (at least on german keyboards):
1) # '
2) + * ~

It's applied to an older version of vt100, so the line numbers may not be 
exactly right, but I checked and they're in the right ball-park. I put the 
changes at the start of the switch statements so it should be easy to find.

Glen, that's great, thank-you. I'll have a go compiling and testing it over the 
next few days if I get time.

Do your changes enable both IE8/Chrome/FF14 *and* FF15, or do your changes make 
it such that the program only works in FF15?

Thanks again,

They're additions, so Chrome and co. should work fine. I did some basic testing 
and everything seems to be OK in all browsers. I'd love to hear how this 
behaves on other nationality keyboards, though. I have a UK keyboard.

Thanks a lot for writing this very useful pease of software! I'm using your 
shellinabox since some time and I'm very satisfied with it. I further analysed 
and found the following keycodes. However, I don't understand your modifier 
implementation. Now I'm running on ff14 which is really unsatisfying! I would 
really appreciate some help on this. Probably I'll find time in the next 
weeks...

Ok, I found some time. I fixed the problem with the German keyboard. However, 
the fix is really stupid, because I still don't understand the meta-key 
handling. The patch is against the version source 2.14. The attached binary can 
be used in Debian. Just install the shellinabox_2.9-1_i386.deb package and 
replace the binary with the attached one.

Changes:
- fix keyboard problem (tested with German keyboard)
- change window title to "News"
- clear screen if connection is lost

I hope it can help someone.

Hi,

I have a different approach to fix this problem. Firefox is correctly creating 
the keyPress events with charCodes. So the only thing to do, is to ignore the 
keys during keyDown and let the keyPress event handle the keys. So the new 
keyCodes simply should be recognized as normal keys.

Hi, there's still a problem with french layout keyboard even with the latest

Following keyCodes are not caught :
 ^ (160 - dead key)
 $ (164)
 * (170)
 ù (165)
 ! (161)
 : (58)
 < (60)

Found keycodes on http://www.asquare.net/javascript/tests/KeyCode.html

I'll try to find a solution by myself but it'll take some time, perhaps someone 
can find an answer more quicker.

What would be the required set of tests to get one of these patches applied to 
the main code stream for Shell In a Box?  I'm willing to test on EN_US 
keyboards with a smattering of distros, but I don't use the foreign keyboards. 
I have other minor changes to the source for my implementation on Debian Wheezy 
so it would be nice to not fork very far from the main code.  For now I can 
work with the copy/paste from text editor workaround, but that isn't a long 
term solution.

I'm on a windows 7 client with FF 35.

FWIW you can use the "minus" key in the 10 key part of your keyboard as a 
workaround for the "dash" key not working...no underscore (etc.) though.  Or 
use Chrome etc.  (can't believe google code doesn't let you *edit* a comment. 
yikes. maybe that's why it is going away LOL).
