This may work, unfortunately I don't have test apps that fail.
The way it works is by using an NSImage class initWithPasteboard:
method, which we then get the TIFFRepresentation of, and convert
to PNG or JPEG.
The TIFFRepresentation uses NSTIFFCompressionNone; which should be
lossless.
instead of calling CFRunLoopRun() directly. The leak wasn't reproducible on
this machine, but someone was able to produce a leak trace with Instruments
that indicates it was leaking in the CFRunLoopRun() path.
x-input.m: dequeue and ignore events when pbproxy_active is false.
x-selection.h: add an is_active method that is used by x-input.m to ignore
events.
x-selection.m: Handle nearly every preference, except for primary_on_grab,
which I don't really understand yet.
Remove some unnecesssary headers.
Remove some dead code that was never called or used in pbproxy.
Make use of an NSAutoreleasePool in x_init. It could potentially cause a leak
on a startup without this.
Start adding reload_preferences to the x_selection class, as well as event
handling for that.
NSAutoreleasePool. Now the usage is consistent. In x_input_run()
we create a pool, and release it after processing the XEvents.
Add some getpid() output to main for debugging. It needs a bit more
testing before the next release.
Don't retain the NSPasteboard as the old code did. That may have
contributed to the leak, and it made it so that we needed the
NSAutoreleasePool created in main().
Remove the _known_types, and _pasteboard instance variables from
the x_selection class. They aren't needed anymore.
The leaks program now indicates 0 leaks after some usage. I want
to test further, but this seems much better, and my memory usage
graph indicates it's not growing.
Move the struct atom_list into the x-selection class, so that it's
no longer a global variable named atoms. This may ease pthread
integration and reduce the chances of symbols conflicting.
INCR transfers mixed with a CLIPBOARD change.
Fix a bug with some UTF-8 transfers. I can only guess that my UTF-8
tests before were inadequate. I can now copy/paste any characters between
uxterm and Textedit.app.
We can now copy and paste images to and from X11. Text copying and
pasting works as well.
The NSPasteboard can contain TIFF or PICT images, and pbproxy will
translate to an image/png or image/jpeg request, and list those in the
TARGETS.
I added a description of the basic design at the top of x-selection.m.
I removed the request_data x_selection class struct. It's not needed.
Add TRACE() calls where appropriate to try to figure out why we are losing CLIPBOARD at times, after transferring PRIMARY to the NSPasteboard.
Use the new pbproxy_clipboard_to_pasteboard where appropriate.
