From e3374bb48daa0235811d384bce55e39b6cf6abda Mon Sep 17 00:00:00 2001 From: Tim Potter Date: Tue, 2 Aug 2005 06:10:31 +0000 Subject: r8910: An initial parser to parse structures in smb_interfaces.h. This will be used to generate ejs objects for making raw smb calls. Running 'make smb_interfaces' should run the build_smb_interfaces.pl script which at the moment only displays a dump of the parsed data. Const is also not working right now but it's bedtime. (This used to be commit 1be5f55d7f6926bf7266ea72623990f0bb558c94) --- source4/build/pidl/smb_interfaces.pm | 1200 ++++++++++++++++++++++++++++++++++ source4/build/pidl/smb_interfaces.yp | 215 ++++++ source4/build/smb_build/makefile.pm | 7 + 3 files changed, 1422 insertions(+) create mode 100644 source4/build/pidl/smb_interfaces.pm create mode 100644 source4/build/pidl/smb_interfaces.yp (limited to 'source4/build') diff --git a/source4/build/pidl/smb_interfaces.pm b/source4/build/pidl/smb_interfaces.pm new file mode 100644 index 0000000000..de8b704b17 --- /dev/null +++ b/source4/build/pidl/smb_interfaces.pm @@ -0,0 +1,1200 @@ +#################################################################### +# +# This file was generated using Parse::Yapp version 1.05. +# +# Don't edit this file, use source file instead. +# +# ANY CHANGE MADE HERE WILL BE LOST ! +# +#################################################################### +package smb_interfaces; +use vars qw ( @ISA ); +use strict; + +@ISA= qw ( Parse::Yapp::Driver ); +#Included Parse/Yapp/Driver.pm file---------------------------------------- +{ +# +# Module Parse::Yapp::Driver +# +# This module is part of the Parse::Yapp package available on your +# nearest CPAN +# +# Any use of this module in a standalone parser make the included +# text under the same copyright as the Parse::Yapp module itself. +# +# This notice should remain unchanged. +# +# (c) Copyright 1998-2001 Francois Desarmenien, all rights reserved. +# (see the pod text in Parse::Yapp module for use and distribution rights) +# + +package Parse::Yapp::Driver; + +require 5.004; + +use strict; + +use vars qw ( $VERSION $COMPATIBLE $FILENAME ); + +$VERSION = '1.05'; +$COMPATIBLE = '0.07'; +$FILENAME=__FILE__; + +use Carp; + +#Known parameters, all starting with YY (leading YY will be discarded) +my(%params)=(YYLEX => 'CODE', 'YYERROR' => 'CODE', YYVERSION => '', + YYRULES => 'ARRAY', YYSTATES => 'ARRAY', YYDEBUG => ''); +#Mandatory parameters +my(@params)=('LEX','RULES','STATES'); + +sub new { + my($class)=shift; + my($errst,$nberr,$token,$value,$check,$dotpos); + my($self)={ ERROR => \&_Error, + ERRST => \$errst, + NBERR => \$nberr, + TOKEN => \$token, + VALUE => \$value, + DOTPOS => \$dotpos, + STACK => [], + DEBUG => 0, + CHECK => \$check }; + + _CheckParams( [], \%params, \@_, $self ); + + exists($$self{VERSION}) + and $$self{VERSION} < $COMPATIBLE + and croak "Yapp driver version $VERSION ". + "incompatible with version $$self{VERSION}:\n". + "Please recompile parser module."; + + ref($class) + and $class=ref($class); + + bless($self,$class); +} + +sub YYParse { + my($self)=shift; + my($retval); + + _CheckParams( \@params, \%params, \@_, $self ); + + if($$self{DEBUG}) { + _DBLoad(); + $retval = eval '$self->_DBParse()';#Do not create stab entry on compile + $@ and die $@; + } + else { + $retval = $self->_Parse(); + } + $retval +} + +sub YYData { + my($self)=shift; + + exists($$self{USER}) + or $$self{USER}={}; + + $$self{USER}; + +} + +sub YYErrok { + my($self)=shift; + + ${$$self{ERRST}}=0; + undef; +} + +sub YYNberr { + my($self)=shift; + + ${$$self{NBERR}}; +} + +sub YYRecovering { + my($self)=shift; + + ${$$self{ERRST}} != 0; +} + +sub YYAbort { + my($self)=shift; + + ${$$self{CHECK}}='ABORT'; + undef; +} + +sub YYAccept { + my($self)=shift; + + ${$$self{CHECK}}='ACCEPT'; + undef; +} + +sub YYError { + my($self)=shift; + + ${$$self{CHECK}}='ERROR'; + undef; +} + +sub YYSemval { + my($self)=shift; + my($index)= $_[0] - ${$$self{DOTPOS}} - 1; + + $index < 0 + and -$index <= @{$$self{STACK}} + and return $$self{STACK}[$index][1]; + + undef; #Invalid index +} + +sub YYCurtok { + my($self)=shift; + + @_ + and ${$$self{TOKEN}}=$_[0]; + ${$$self{TOKEN}}; +} + +sub YYCurval { + my($self)=shift; + + @_ + and ${$$self{VALUE}}=$_[0]; + ${$$self{VALUE}}; +} + +sub YYExpect { + my($self)=shift; + + keys %{$self->{STATES}[$self->{STACK}[-1][0]]{ACTIONS}} +} + +sub YYLexer { + my($self)=shift; + + $$self{LEX}; +} + + +################# +# Private stuff # +################# + + +sub _CheckParams { + my($mandatory,$checklist,$inarray,$outhash)=@_; + my($prm,$value); + my($prmlst)={}; + + while(($prm,$value)=splice(@$inarray,0,2)) { + $prm=uc($prm); + exists($$checklist{$prm}) + or croak("Unknow parameter '$prm'"); + ref($value) eq $$checklist{$prm} + or croak("Invalid value for parameter '$prm'"); + $prm=unpack('@2A*',$prm); + $$outhash{$prm}=$value; + } + for (@$mandatory) { + exists($$outhash{$_}) + or croak("Missing mandatory parameter '".lc($_)."'"); + } +} + +sub _Error { + print "Parse error.\n"; +} + +sub _DBLoad { + { + no strict 'refs'; + + exists(${__PACKAGE__.'::'}{_DBParse})#Already loaded ?
