spurious spaces inserted on paste

[objarni]

Platform

Firefox 24.0
Windows 7, 64-bit

Reproduction steps

1. open a new pad on piratepad.ca
2. select the row "This pad text is synchronized as you type, so that everyone viewing this page sees the same text. This allows you to collaborate seamlessly on documents!"
3. paste it
4. notice at least one extra space is inserted at some place (just now for me between word 'This' and 'not', on 2nd attempt between 'is' and 'synchronized'
5. Repeat procedure in any other text area on the web (e.g. this github issue tracker) to see that you are not crazy and that it is not a general paste error, but specific to etherpad lite

I don't get this same experience in Chrome fyi: http://beta.etherpad.org/p/3bIPbQgoqq

[JohnMcLear]

Confirmed: Firefox does create this behavior. Heh fsking browsers.

Observation: the insert of the space does not happen instantly on paste but some milliseconds after, upto 0.5 seconds I would say, which makes this even more odd. I just tried to reproduce on Chrome, but could not.

[JohnMcLear]

Ironically as I pasted that comment my browser (Chrome) crashed on me..

[JohnMcLear]

String "one two three four five six seven one two three four five six seven one two three four five six seven four five six seven 1234567" does cause it
String "one two three four five six seven one two three four five six seven one two three four five six seven four five six seven 123456" does not.

Appears to be related to Strlen

[JohnMcLear]

128 chars doesnt cause it
129 chars does.

Anyways I gotta get on with me real work, this should be an interesting bug to fix tho

Related to this bug in Firefox? https://bugzilla.mozilla.org/show_bug.cgi?id=280579 (duplicate of this, better described issue: https://bugzilla.mozilla.org/show_bug.cgi?id=89780)

[JohnMcLear]

Hah I bet, or not, actually looking at it I think maybe we do have some hard wrapping or some such

[objarni]

The result of the whole fat issue history (nr #2 above, 89780) on mozilla was the spawning of a couple of other issues, of which only one had been fixed. The other was completely deserted (no comment, no nothing, marked as "New" even though created 2005... - https://bugzilla.mozilla.org/show_bug.cgi?id=281409)

Confirmed has to do with strings >128, nice one.

Another observation: it does not happen for strings >128 if copied from Notepad, WordPad or Sublime Text 3.

Guess: may it only be when both copying and pasting inside Firefox, no other software involved?

oho, something's happening. interesting find there john... I think we've
had this bug reported a few times already, but haven't gotten that far yet!

[marcelklehr]

I think firefox has it's own clipboard for some reason.. (try copying
sth in firefox, close it and then pasting... didn't work for me some 5
versions ago -- haven't tested it since)
