Mon Aug 27 12:17:17 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* loader.c, metadata.c, metadata.h: Export mono_metadata_type_equal().
	We don't need a MonoMetadata pointer anymore to compare signatures in
	mono_metadata_signature_equal (), update callers.
	Reduced memory usage an number of allocations for MonoMethodHeader and
	MonoMethodSignature.

Sun Aug 26 23:03:09 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* metadata.c: added compare for szarray.

Sun Aug 26 11:34:24 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* class.h, class.c, loader.h, loader.c: export mono_class_from_mono_type ()
	and add a couple more types to it and mono_defaults. Give an hint on

	* class.h, class.c: keep track if a class is also an Enum.
	* loader.c: Implement a couple more types for use in libffi
	marshalling. Gives better diagnostics when failing to dlopen
	a library. Set method->klass for P/Invoke methods, too.

Fri Aug 24 19:30:25 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* class.c, class.h: add a MonoType this_arg to MonoClass that
	represents a pointer to an object of the class' type that
	can be used by the interpreter and later the type cache.
	Add best guess alignment info for valuetype objects.

Fri Aug 24 15:50:31 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* metadata.h, metadata.c, class.h, class.c: squeezed MonoParam
	into MonoType: one less level of indirection and allocation and
	simplifies quite a bit of code. Added cache for MonoTypes that are
	used frequently, so that we don't need to allocate them all the time.

2001-08-24  Dietmar Maurer  <dietmar@ximian.com>

	* class.c (mono_class_create_from_typedef): System.Enum is also a
	value type, although it does not derive from System.ValueType
	(maybe a bug in the ms compiler?)

	* metadata.c (mono_type_size): return the right size for value types

	* loader.c (mono_get_method): only initialize method header if not abstract

	* class.c (mono_class_from_mono_type): use mono_default values. 

2001-08-23  Dietmar Maurer  <dietmar@ximian.com>

	* *: use MonoClass pointers instead of <type_tokens>
	
	* class.h: new flag: metadata_inited.

	* class.c (mono_class_metadata_init): impl.
	(mono_class_instance_size): impl.
	(mono_class_data_size): impl.

Wed Aug 22 16:27:30 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* metadata.c, loader.h, loader.c, image.h, image.c, class.h, class.c:
	MonoClass now has the name and name_space fields. 
	MonoMethod has a pointer to its MonoClass, instead of MonoImage.
	mono_get_method () takes and optional MonoClass as argument.
	Removed mono_typedef_from_name() and added mono_class_token_from_name()
	instead that takes advantage of a map from class names to typedef
	tokens in MonoImage.

Tue Aug 21 18:54:58 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* metadata.c: zero is not a valid alignment boundary.
	Merge MONO_TYPE_VOID in default decoding code.

2001-08-21  Dietmar Maurer  <dietmar@ximian.com>

	* image.h: merged MonoMetadata into MonoImage

	* class.h: cleanup of MonoArrayClass, use a MonoClass pointer to
	identify the type of elements.

Mon Aug 20 19:39:00 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* blob.h: fix MONO_TYPE_TYPEDBYREF value.
	* cil-coff.h: split MonoMSDOSHeader and add size info.
	* image.c: add some consistency checks.
	* metadata.c: fix row size computation: one programmer
	error and one LAMESPEC. Handle MONO_TYPE_TYPEDBYREF.
	add explanation for the locator routine.
	Fix decoding of size in method header.
	
2001-08-20  Miguel de Icaza  <miguel@ximian.com>

	* assembly.c 	(g_concat_dir_and_file): Use _S for string concat.
	(g_concat_dir_and_file): Bring g_concat_dir_and_file
	function from gnome-libs.  This uses the right path separator
	based on the OS, and also works around a bug in some systems where
	a double slash is not allowed. 
	(default_assembly_name_resolver): Use g_concat_dir_and_file
	(mono_assembly_open): ditto.

2001-08-20  Dietmar Maurer  <dietmar@ximian.com>

	* metadata.c (mono_metadata_signature_equal): impl.

	* *: void is now a realy MonoType (instead of using NULL)
	
	* metadata.c (do_mono_metadata_parse_type): use
	mono_metadata_parse_type to parse void value.

Sat Aug 18 12:51:28 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* metadata.c, metadata.h: in the signature and method header store
	only the space required for holding the loca vars and incoming arguments.

2001-08-15  Dietmar Maurer  <dietmar@ximian.com>

	* metadata.c (do_mono_metadata_parse_type): treat void like any
	other type (instead of assigning NULL);

Sat Aug 4 12:46:02 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* metadata.h, metadata.c: add mono_metadata_decode_row_col () to
	decode a single column from a row in a metadata table and changes
	to take advantage of it in the typedef locator (gives a nice speed up).
	Store offset info for function params.

2001-08-02  Dietmar Maurer  <dietmar@ximian.com>

	* image.h (MONO_IMAGE_IS_CORLIB): removed 

Wed Aug 1 22:54:08 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* assembly.c: how could mono_assembly_close () had ever worked?
	* metadata.c, metadata.h: provide offset info for local vars.
	Implement mono_type_size () to take care of alignment as well
	as size (it was mono_field_type_size in cli/class.c before).

	cil-coff.h, image.c, image.h, pedump.c, rawbuffer.c, rawbuffer.h, row-indexes.h,
	tokentype.h: massive namespace cleanup.

Mon Jul 30 20:11:01 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* metadata.h, metadata.c: decode exception clauses when parsing method header.

2001-07-27  Dietmar Maurer  <dietmar@ximian.com>

	* metadata.c (mono_metadata_free_type): added check for type !=
	NULL (void) before calling mono_metadata_free_type()

Thu Jul 26 19:11:19 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* metadata.h, row_indexes.h: added header with enumerations to use
	to index in the columns from tables in metadata and to decode coded
	tokens: we should start using this instead of embedding magic numbers
	all over the code.

Thu Jul 26 13:03:27 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* assembly.c, cil-coff.h, image.c, image.h, pedump.c, typedef.c:
	Move metadata_t info from cli_image_info_t to MonoImage, where
	it's easily accessible. Changed all the uses accordingly.
	Added the method and class caches to MonoImage.
	* metadata.c, metadata.h: Changed mono_metadata_decode_blob_size ()
	and mono_metadata_decode_value () signature to be more consistent
	with the other parse functions (and simplify code). Taken advantage
	of zero-length array allocation with GCC. Removed reduntant (and
	wrong) MonoFieldType struct and use MonoParam instead. Changed
	mono_metadata_parse_field_type () to use common code for parsing.
	Added mono_metadata_typedef_from_field () and
	mono_metadata_typedef_from_method () to lookup a typedef index from a
	field or method token.
	Pack the MonoRetType structure more tightly (fits in 8 bytes now).

2001-07-23  Miguel de Icaza  <miguel@ximian.com>

	* metadata.c (mono_metadata_parse_field_type): Implement. 
	(do_mono_metadata_parse_type): Split engine from
	mono_metadata_parse_type, so that we can create smaller structures
	for things that just have one pointer to the MonoType (look at
	the MonoFieldType)

2001-07-20  Miguel de Icaza  <miguel@ximian.com>

	* metadata.c (mono_metadata_parse_mh): Correct the implementation,
	as Jan Gray found out, it is incorrect. 

2001-07-18  Miguel de Icaza  <miguel@ximian.com>

	* assembly.c: Implement asssembly loading.  This loads an image
	and loads all the referenced assemblies.  Come to think of it, we
	could always do lazy loading of the assemblies. 

	* image.c (mono_image_open): Keep loaded images in a hashtable.

	* image.h (MonoImage): Add reference count.

2001-07-17  Miguel de Icaza  <miguel@ximian.com>

	* assembly.c (mono_assembly_open): Keep track of the file name in
	case the assembly has no ASSEMBLY table.

	* metadata.h: Fixed Paolo's quick hack.  Put the documnentation
	from get.c here.

	* metadata.c, metadata.h: decode local vars in method header
	parse function. Change callers accordingly.

Sun Jul 15 17:40:47 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* metadata.h, cil-coff.h: protect against multiple inclusion.
	Added some new structures to hold information decoded from metadata:
	MonoType, MonoParam, MonoArray, MonoMethod, MonoMethodSignature
	and relevant decoding/free functions.
	* metadata.c: implement decoding functions. Add warning for out of bounds
	index in mono_metadata_locate(). Implement mono_get_method () to retreive
	all the info about a method signature and invocation. Remove check on
	uninitialized local var in parse_mh() and fix memory leak.

2001-07-12  Miguel de Icaza  <miguel@ximian.com>

	* metadata.h: More macros.

	* tokentype.h: New file.

Fri Jul  6 11:30:53 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* assembly.c: added a consistency check and initialize
	some structures with g_new0().
	* metadata.c: fixed a couple more bugs in table size computation
	and add other checks for out-of bound access to metadata.

Thu Jul  5 22:34:21 CEST 2001 Paolo Molaro <lupus@ximian.com>

	* metatada.c: fix bugs computing table sizes. Spew a
	warning when index in string heap is out of bounds.

2001-07-04  Miguel de Icaza  <miguel@ximian.com>

	* metadata.h: Add a couple of macros to manipulate tokens. 

Tue Jul  3 18:33:32 CEST 2001 Paolo Molaro <lupus@ximian.com>

2001-07-01  Miguel de Icaza  <miguel@ximian.com>

	* metadata.c (mono_metadata_user_string): New function, provides
	access to the UserString heap. 

2001-06-27  Miguel de Icaza  <miguel@ximian.com>

	* metadata.c: Add inline documentation.

2001-06-26  Miguel de Icaza  <miguel@ximian.com>

	* propertyattr.h, paramattr.h, methodsem.h, methodattr.h: New
	files. 

2001-06-22  Miguel de Icaza  <miguel@ximian.com>

	* typeattr.h: New file, TypeAttribute flags. 

2001-06-21  Miguel de Icaza  <miguel@ximian.com>

	* mono/metadata/assembly.c (mono_assembly_ensure_section_idx,
	mono_assembly_ensure_section): Section loading code.
