Regressed between 2004-05-07-08 and 2004-05-08-08.  Checkins:

http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=all&branch=HEAD&branchtype=match&dir=&file=&filetype=match&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=2004-05-07+08%3A00%3A00&maxdate=2004-05-08+08%3A00%3A00&cvsroot=%2Fcvsroot

Possible culprits:

Bug 237760, caillon's checkin for style stuff, bug 242734.

Note that this is not a "strange character" -- it's just the focus rect being
mis-sized.

whoa bz, you are too fast for me... I was still downloading a build to hunt for
the regression date

Patch for real

jst, this is all your fault, man!  The null terminator is _not_ part of the
string!

(i.e. this was caused by bug 242734)

Comment 8

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

The implementation of SetText (in nsGenericDOMDataNode.cpp) assumes its argument
is null-terminated.

Comment 9

[Boris Zbarsky [:bzbarsky]]

Hmm.. so it does, when it does the nsDependentString thing.  We should probably
fix that, since the call signature makes it look that no such assumptions, and
neither does the API (or document the assumption and change this patch accordingly).

Attachment: Don't assume aBuffer is null-terminated.

Sorry for not replying here before, I had some major email problems all day
yesterday and missed this discussion.

How about this, in addition to bz's patch?

Don't assume aBuffer is null-terminated.

What about the char* version of SetText?  It has the same issue, no?

Comment 13

[Johnny Stenback (:jst)]

Yeah, duh, fixed locally. Checking in (r+sr=bz over IRC).

Comment 14

[Johnny Stenback (:jst)]

Fixed.
