No, I am mistaken. The new code doesn't support overriding arbitrary
global options in a section. This won't work in general:
[global]
someOption 1
[phc2sys]
someOption 2
That only works if "someOption" is marked as port-specific item.
However, this can be done later on. Something like this:
enum config_section {
GLOBAL_SECTION,
PORT_SECTION,
+ PROGRAM_SECTION,
UNKNOWN_SECTION,
};
#define CFG_ITEM_STATIC (1 << 0) /* statically allocated, not to be
freed */
#define CFG_ITEM_LOCKED (1 << 1) /* command line value, may not be
changed */
#define CFG_ITEM_PORT (1 << 2) /* item may appear in port sections */
+ #define CFG_ITEM_PROG (1 << 3) /* default may be overriden in a
program section */
The parse_item() code would have to change. But that will be easier
to do, once all of the manual parsing in parse_port_setting() and
parse_global_setting() is gone.
Whether we implement this or not depends on whether we want a
single configuration file for all three programs or whether we just
say, each program must have its own file.
Thanks,
Richard
