env: Add environment variable flags

2012-12-13T18:46:56+00:00

Currently just validates variable types as decimal, hexidecimal,
boolean, ip address, and mac address.

If the entry is not found in the env ".flags", then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.

env: Add support for callbacks to environment vars

2012-12-13T18:46:55+00:00

Add support for per-variable callbacks to the "hashtable" functions.

!!!fix comment in callback

env: Refactor apply into change_ok

2012-12-13T18:46:55+00:00

Move the read of the old value to inside the check function.  In some
cases it can be avoided all together and at the least the code is only
called from one place.

Also name the function and the callback to more clearly describe what
it does.

Pass the ENTRY instead of just the name for direct access to the whole
data structure.

Pass an enum to the callback that specifies the operation being approved.

env: make "env default" selective, check and apply

2012-09-18T19:01:52+00:00

Change the syntax (user API) for "env default":
  -f: override write-once variables
  var... : accept individual variable(s)
  -a: all (resetting the whole env is NOT the default behavior)

Enable variable checking and make changes effective by
enabling do_apply argument to himport_r().

env: add check/apply logic to himport_r()

2012-09-18T19:01:52+00:00

Change hashtable so that a callback function will decide whether a
variable can be overwritten, and possibly apply the changes.

So add a new field to struct hsearch_data:

 o "apply" callback function to check whether a variable can be
    overwritten, and possibly immediately apply the changes;
    when NULL, no check is performed.

And a new argument to himport_r():
 o "do_apply": whether to call the apply callback function

NOTE: This patch does not change the current behavior.

env: remove value from boolean defines

2012-01-05T15:35:54+00:00

Several boolean defines have a value assigned.
Remove the value as defining the symbol is enough.
