I received a report from a customer today that my app hangs when they
paste text into a NSTextView (under 10.5.1). The customer was kind
enough to include the hang report. It does appear that this goes deep
in the bowels of the text view, although it does touch my code briefly
(readSelectionFromPasteboard:type:) -- that quickly passes it on to
the NSTextView readSelectionFromPasteboard:type: .
I recently started setting [layoutManger
setAllowsNonContiguousLayout:YES]; under Leopard. Are the two perhaps
related? Or does this sound like a different bug?
I'm trying to understand what I can do to help reproduce this bug on
my end so I can log a bug with Apple (since I know the first response
will be to get more info).
The user has sent in the hang reports to Apple, which may contain more
info -- but I don't know how those are processed or what priority they
may be given compared to developer generated bugs.
Any help or insight one can give is appreciated.
I've included the sampling that was generated:
At first glance this looks like a hang somewhere in the depths of the
font loading machinery, and nothing to do with either you or Cocoa.
Can the customer reproduce it? If so, you might need detailed
information about the configuration of the customer's machine, perhaps
the specific fonts installed, to be able to reproduce it yourself. It
may not be reproducible at all. The customer's bug report will be
attended to; the main difficulty is with reproducibility. The
advantage of developer bug reports is that they often contain more
relevant details, and that we can (for example) ask developers to do
things like capture backtraces in gdb, but if you can't reproduce it
yourself then that's not possible.
