db1326aa5e Dynamic attributes are now declared in per-protocol grammar files instead 
of filter/config.Y. Bird now compiles even if you disable RIP.

Removed RTA and IMPOSSIBLE tokens (unused).

Removed superfluous comment in filter.h.

I've tried to do my best, but Pavel, please check these changes.

6781e5213b FIXME's cleaned up: I have actually fixed things without killing 
comments.

There are no urgent FIXME's in filters. Perhaps we should start with
documentation?

4aa885a53c Filters: fix rta access to use ->aux field. 1999-11-25 13:42:49 +00:00

455ca441d9 Check that prefixes are really prefixes + fix config file to 
comply. (:-( 1.2.3.4/8 looks nicer than 1.0.0.0/8).

48f9e01954 Filters: write access to dynamic attributes should actually work. It 
would be nice to find method of testing such beasts.

f31156ca21 Filters: first parts of extended attributes being read-write. It can 
not actually work since I do not do rta/rte cow, yet.

c7b43f33ae Split inst->code into inst->code and inst->aux. Both are only 16 bit, 
so aux is suitable for storing type but not much more.

4515bdba4f Fixed order of arguments for function call. 
Enumeration types should work once CF_ENUM() is ready.

Created test.conf for testing of filters. (I'm currently thinking
about ./tests in root directory which will just fire all available
tests...)

cb8034f42c First try on enumerational types. 
Mj's noassoc removed: this brings back shift/reduce conflict but
it makes parser actually work. Mj please check it. IF/THEN/ELSE still
will not work.

d3dd620b96 Filters: permit variables of prefix types, cleanup around 
variables. TODO list added, hopefully complete. Use new features of
filters in bird.conf

7db7b7db60 Case arg { 1: printf "one"; } works. You can not use two commands 
after one label, yet.

6542ece91a Function calling in filters works - somehow. Calling syntax is 
currently very ugly, beware. Variables are not really local - that
needs to be fixed.

4107df1d1b Implemented two new symbol handling functions: 
o  cf_define_symbol() -- it assigns a meaning to a symbol, bailing
     out if it already has one.
  o  cf_find_symbol() -- finds symbol by name and creates it if not found.

Also modified filter/config.Y to make use of the first function.

36bbfc704c Updated filters: they now actually see IP/pxlen of net being filtered, 
gateway, and who told us, so they can do usefull jobs from now on.

38506f71b0 Sets of integers now actually work. Sets of IP will work as soon as 
compare function is ready.

23b1539bf9 Filters upgraded - a bit. Moved code to filter.c because it is where 
it belongs. (f-util.c stays there for auxiliary and non-important things.)

ba92164871 Update of filters towards new interface. 1999-03-29 20:21:28 +00:00

e0f2e42f4f A couple of filter tweaks: 
o  Introduced struct filter which serves as an external reference
      to filter. Using struct symbol for this is unwise since it doesn't
      allow extra information attached to the filter and it also forces
      all filters to be named.
   o  Implemented config rule 'filter' which matches either named filter
      or an embedded unnamed filter (`{ <filter> }').
   o  Fixed totally bogus comment at the top of filter.h.
   o  Added a missing prototype for f_run() to filter.h.

c9b6670608 Original expr' is back, filter expressions renamed to term'. 
In the future, we'll allow any filter term in place of `expr' and we'll
just evaluate it immediately, but not now as we have no evaluation
routines.
