Comment #4 on issue 15891 by j...@chromium.org: implement showModalDialog on
mac & linux
http://code.google.com/p/chromium/issues/detail?id=15891
BTW I just realized what the problem is: it's because SyncChannel can't run
a nested
message loop without the cross process waitable events, which aren't
implemented on
posix yet. I have thought a lot about how to get around using them, but
since the
same event needs to be used for each RenderView/RenderViewHost/plugin code
which are
all in different processes, I think it'll be too complicated to try to do
this with
some sort of IPC.
This document shows how to implement named events (i.e. cross process) in
Linux: http://www.ibm.com/developerworks/library/l-ipc2lin2.html
It uses System V semaphores, which apparently work on Mac as well. Perhaps
this
doesn't have to be used for all events, just for named ones. Maybe we can
create a
normal (in-process) waitable event and also this system v semaphore, and
use the
latter to set the former?
I have an old test case for this at
http://www/~jabdelmalek/chrome/test/plugins/showmodaldialog.html which
exercises
plugins as well.
