7.4
Something about Pike.Backend and #pragma save_parent.
Rev: CHANGES:1.58
437:
This is an extended version of Parser.XML.Tree that can handle namespaces according to the W3C namespace specification.
+
o Pike.Backend and Pike.DefaultBackend
+
It is now possible to start several backends, and to start the
+
default backend without having to return negative from main().
+
+
Example:
+
while(things_to_do) {
+
mixed err;
+
if (err = catch{
+
while(things_to_do) {
+
Pike.DefaultBackend(3600.0);
+
} }) {
+
master()->handle_error(err);
+
}
+
}
+
o Protocols.XMLRPC Implements most features of the XML-RPC standard.

+
o Individual parent object pointers are now only kept when needed
+
In Pike 7.0 and 7.2 all objects kept a pointer to the surrounding
+
object. This led to an excess of circular datastructures, which
+
ment that the garbage collector had to kick in more often. In Pike
+
7.4 parent object pointers are only kept if the object actually
+
refers to identifiers in the parent. This change however affects
+
the behaviour of object_program() and function_object().
+
+
o __pragma_save_parent__
+
To change the default parent object pointer behaviour to the
+
Pike 7.0/7.2 default it is possible to
+
add_constant("__pragma_save_parent__", 1).
+
+
o #pragma save_parent
+
To get the Pike 7.0/7.2 parent object pointer behaviour for a
+
single compilation unit use the #pragma save_parent.
+
+
o #pragma dont_save_parent
+
To restore the default Pike 7.4 parent object pointer behaviour from
+
#pragma save_parent or __pragma_save_parent__ for a single compilation
+
unit use the #pragma dont_save_parent.
+
o Thread.Condition()->wait() This function takes a mutex lock to unlock while it waits on the condition. That argument was previously optional, but not any
839:
o it is possible to change predefines without forking a new pike add_predefine()/remove_predefine()
-
o #pragma save_parent
-
o #pragma dont_save_parent (overrides constant __pragma_save_parent__)
-
+
o dont_dump_module *FIXME: grubba* System.usleep()/nanosleep()
