This should isolate any coverity warnings on 64-bit platforms (where LONG_MAX is larger than any possible 32 bit value) to a single spot, or possibly eliminate it. This is needed for the unsigned 64 bit case, and on 32 bit systems, as PyInt_FromLong is limited to a signed "long" int. The compiler should be able to eliminate many of these calls with the embedded type knowlege.

Introduction: ============= This directory contains the source code of the pidl (Perl IDL) compiler for Samba 4. The main sources for pidl are available using Git as part of the Samba source tree. Use: git clone git://git.samba.org/samba.git Pidl works by building a parse tree from a .pidl file (a simple dump of it's internal parse tree) or a .idl file (a file format mostly like the IDL file format midl uses). The IDL file parser is in idl.yp (a yacc file converted to perl code by yapp) Standalone installation: ======================== Run Makefile.PL to generate the Makefile. Then run "make install" (as root) to install. Internals overview: =================== After a parse tree is present, pidl will call one of it's backends (which one depends on the options given on the command-line). Here is a list of current backends: -- Generic -- Parse::Pidl::Dump - Converts the parse tree back to an IDL file Parse::Pidl::Samba4::Header - Generates header file with data structures defined in IDL file Parse::Pidl::NDR - Generates intermediate datastructures for use by NDR parses/generators Parse::Pidl::ODL - Generates IDL structures from ODL structures for use in the NDR parser generator Parse::Pidl::Test - Utility functions for use in pidl's testsuite -- Samba NDR -- Parse::Pidl::Samba4::NDR::Client - Generates client call functions in C using the NDR parser Parse::Pidl::Samba4::NDR::Parser - Generates pull/push functions for parsing NDR Parse::Pidl::Samba4::NDR::Server - Generates server side implementation in C Parse::Pidl::Samba4::TDR - Parser generator for the "Trivial Data Representation" Parse::Pidl::Samba4::Template - Generates stubs in C for server implementation Parse::Pidl::Samba4::Python - Generates bindings for Python -- Samba COM / DCOM -- Parse::Pidl::Samba4::COM::Proxy - Generates proxy object for DCOM (client-side) Parse::Pidl::Samba4::COM::Stub - Generates stub call handler for DCOM (server-side) Parse::Pidl::Samba4::COM::Header - Generates headers for COM -- Wireshark -- Parse::Pidl::Wireshark::NDR - Generates a parser for the Wireshark network sniffer Parse::Pidl::Wireshark::Conformance - Reads conformance files containing additional data for generating Wireshark parsers -- Utility modules -- Parse::Pidl::Util - Misc utility functions used by *.pm and pidl.pl Parse::Pidl::Typelist - Utility functions for keeping track of known types and their representation in C Tips for hacking on pidl: - Inspect pidl's parse tree by using the --keep option and looking at the generated .pidl file. - The various backends have a lot in common, if you don't understand how one implements something, look at the others. - See pidl(1) and the documentation on midl - See 'info bison' and yapp(1) for information on the file format of idl.yp - Run the tests (all in tests/)
