After a weekend of extensive mail exchange with the signal crew, we 2000-05-14 Michael Natterer <mitch@gimp.org> After a weekend of extensive mail exchange with the signal crew, we finally found that #2742 is not a Gimp bug but a real OSF/1 bug. OSF/1 does _not_ reliably restart read() and write() calls on certain slow devices (pipes). * libgimp/gimpwire.[ch]: guard all read/write calls on the wire with loops checking for EINTR. This has to be done "manually" as glib's GIOChannels return G_IO_ERROR_UNKNOWN on the occurence of EINTR (which is a bug, too). s/int/gboolean and minor cleanups while I was on it (not changing any logic). This fix depends on the current (broken) state of the GIOChannel implementation and is scheduled for removal as soon as glib behaves nicely here. Left SA_RESTART there for the moment in app/main.c. See it as defensive programming or just my fear to change two #2742-related places at the same time. We might choose to remove SA_RESTART later. Many thanks again to Austin, Garry and Tim.
