[mono.git] / mono / metadata / ChangeLog

2002-02-16  Jeffrey Stedfast  <fejj@ximian.com>

        * socket-io.c (convert_sockopt_level_and_name): If the system
        doesn't define SOL_IP or SOL_TCP, get them by hand using
        getprotobyname() and caching the values (because this could be a
        slow operation).
        (ves_icall_System_Net_Sockets_Socket_SetSocketOption_internal):
        Don't attempt to add or drop memberships unless the system
        supports it. Also use the appropriate struct when the system does
        support it. Ie, not all systems have struct ip_mreqn so use struct
        ip_mreq when appropriate.

Fri Feb 15 18:15:44 CET 2002 Paolo Molaro <lupus@ximian.com>

        * reflection.c: handle finally clauses.

Fri Feb 15 15:06:33 CET 2002 Paolo Molaro <lupus@ximian.com>

        * socket-io.c: use g_snprintf() instead of snprintf.

2002-02-14  Jeffrey Stedfast  <fejj@ximian.com>

        * reflection.c (mono_param_get_objects): Cast second argument to
        mono_method_get_param_names to a const char** to silence the
        compiler warning.

        * appdomain.c (mono_domain_assembly_open): Put parens around the
        truth statement in the for-loop.

        * unicode.c (iconv_convert): Got rid of a compiler warning about
        int i being unused when the system has a new iconv.
        (iconv_get_length): Same.

        * image.c (load_class_names): Cast the second argument to
        g_hash_table_insert() to char* to hush compiler warnings about the
        arg being a const.
        (mono_image_open): Same here.

        * socket-io.c: Don't conditionally include sys/filio.h or
        sys/sockio.h here anymore since we now get them from
        io-layer/io-layer.h
        (inet_pton): If the system doesn't support inet_aton, implement
        using inet_addr and also #define INADDR_NONE if it isn't defined
        by the system.

Thu Feb 14 19:01:06 CET 2002 Paolo Molaro <lupus@ximian.com>

        * metadata.c, metadata.h: added function to get packing and size info
        of a typedef.
        * reflection.h, reflection.c: handle field RVA data. Save info about
        the table layout if needed. Assign typedef indexes to all the types
        before dumping the info about them to avoid forward reference problems.

2002-02-14  Dietmar Maurer  <dietmar@ximian.com>

        * socket-io.c (convert_sockopt_level_and_name): ifdef
        SO_ACCEPTCONN because it is not defined on my system (old debian)

Thu Feb 14 11:49:30 CET 2002 Paolo Molaro <lupus@ximian.com>

        * opcode.c: use stddef.h to get NULL.

2002-02-14  Jeffrey Stedfast  <fejj@ximian.com>

        * socket-io.c: conditionally include sys/filio.h and sys/sockio.h
        for FIONBIO, FIONREAD and SIOCATMARK.
        (ves_icall_System_Net_Dns_GetHostByAddr_internal): SunOS doesn't
        define INADDR_NONE and besides, inet_addr() is deprecated and
        should not be used. Use inet_pton() instead - it also has the
        added bonus that it can easily handle IPv6 addresses as well.
        (inet_pton): Implement using inet_aton() ifndef HAVE_INET_PTON.

Wed Feb 13 23:00:21 CET 2002 Paolo Molaro <lupus@ximian.com>

        * decimal.c: remove _MSC_VER conditional.

        GetSocketOption and SetSocketOption

Wed Feb 13 19:20:01 CET 2002 Paolo Molaro <lupus@ximian.com>

        * assembly.cs: better resolver: use it instead of some kludgy
        code.

Wed Feb 13 18:25:55 CET 2002 Paolo Molaro <lupus@ximian.com>

        * reflection.c: the best way to speed-up the compiler is to avoid
        infinite loops.

2002-02-13  Dietmar Maurer  <dietmar@ximian.com>

        * class.c (mono_class_vtable): changed the object layout
        (obj->vtable->class). 
        (mono_class_create_from_typespec): consider MONO_TYPE_PTR

Tue Feb 12 20:06:01 CET 2002 Paolo Molaro <lupus@ximian.com>

        * icall.c (ves_icall_appdomain_get_default_assemblies): put this
        code back.  This should return the assemblies that are loaded by
        the runtime on behalf of an application domain. 

        The current implementation is still broken, it just returns every
        assembly loaded, but until we get real applications domain this
        will do.

2002-01-23  Dietmar Maurer  <dietmar@ximian.com>

        * icall.c (ves_icall_appdomain_get_cur_domain): runtime_init the
        AppDomain object.

Tue Jan 22 22:43:47 CET 2002 Paolo Molaro <lupus@ximian.com>

        * class.c: load also nested classes on class init.
        System.ValueType instance methods gets passed boxed
        values, unless methods in derived classed that get a pointer to the
        data.
        * icall.c: use better name parsing code in GetType().
        * image.c, image.h: add mono_image_loaded ().
        * metadata.c, metadata.h: add mono_metadata_nesting_typedef ().

        * class.c (mono_class_init): set min_align to 1 (instead of 0)
        (mono_class_value_size): use min_align

2002-01-20  Dick Porter  <dick@ximian.com>

        * threads.h:
        * threads.c: Replaced all instances of WapiHandle * with HANDLE,
        so it compiles on w32.

2002-01-17  Dietmar Maurer  <dietmar@ximian.com>

        * metadata.c (mono_type_stack_size): impl.

        * class.c (mono_class_get_field): impl. memberref token

        * threads.c: Make the runtime's idea of infinite timeouts coincide
        with the class library's

        Fix a particularly egregious bug in mono_thread_cleanup(). That
        code was so utterly bogus it must have been written on a Monday.

Mon Jan 14 17:01:03 CET 2002 Paolo Molaro <lupus@ximian.com>

        * reflection.h: add subtypes field to TypeBuilder.
        * reflection.c: encode constants for literal fields.
        Handle subtypes. Fix user string token (and add a zero byte)
        at the end.
        
2002-01-14  Dietmar Maurer  <dietmar@ximian.com>

        * reflection.c: handle byref and szarray types. Handle methods without
        body (gets P/Invoke compilation working). Handle types and fields in
        get_token ().
        * reflection.h: add rank to MonoTypeInfo.

Tue Jan 8 22:47:44 EST 2002 Matt Kimball <matt@kimball.net>
        * object.c: mono_string_new should return a NULL when the string 
        passed in is NULL -- not try to deference it.
        
Sat Jan 5 15:48:04 CET 2002 Paolo Molaro <lupus@ximian.com>

        * icall.c: hack to make IsSubType work for TypeBuilders.

        doesn't complain. Removed \# at end of list.

Thu Jan 3 23:17:17 CET 2002 Paolo Molaro <lupus@ximian.com>

        * reflection.c: get token for a method ref. Set return type of

2001-12-21  Miguel de Icaza  <miguel@ximian.com>

        * rawbuffer.cs: Added native Win32 implementation, avoids using
        mmap on Cygwin.  This patch is from Dan Lewis (dihlewis@yahoo.co.uk)

Thu Dec 20 20:11:26 CET 2001 Paolo Molaro <lupus@ximian.com>

        * class.c: make the low-level routines handle the cache.

Thu Dec 20 15:20:35 CET 2001 Paolo Molaro <lupus@ximian.com>

        * image.c: fopen (file, "rb") ("David Dawkins" <david@dawkins.st>).

        mono_string_chars()

        * object.c: Added mono_string_to_utf16(), which copies the non

        Check code: branches, maxstack, method calls.

2001-12-04  Dietmar Maurer  <dietmar@ximian.com>

        * object.c (mono_object_allocate): removed static, so that the jit
        can allocate value types.

        * icall.c (ves_icall_System_DateTime_GetNow): impl.

Mon Dec 3 17:02:01 CET 2001 Paolo Molaro <lupus@ximian.com>

        * class.c: init enum types right away and register the

        * verify.h, verify.c: first cut of the verifier.
        * pedump.c: add --verify switch to verify metadata tables.
        * tabledefs.h: add some missing enums.

2001-11-30  Dietmar Maurer  <dietmar@ximian.com>

        * class.c (mono_install_runtime_class_init): impl.
        (mono_class_init): renamed mono_class_metadata_init to
        mono_class_init, also removed the metadata_inited flag

        * object.c (mono_object_isinst): use faster algorithm

2001-11-30  Radek Doulik  <rodo@ximian.com>

        * mono-endian.h: reverted last change
        added function prototypes

        * Makefile.am (libmetadata_a_SOURCES): reverted my last change and
        add mono-endian.c back

        * mono-endian.c: returned back, as Paolo pointed out, it's needed
        for unaligned access, I've mistaked it with endianess. I am
        sorry.
        (mono_read16): fix reverted endianess
        (mono_read64): ditto
        (mono_read32): ditto

        * metadata.h, metadata.c: remove params_size and locals_size and their
        calculation from the metadata code: they are only usefult to the
        interp.

2001-11-29  Radek Doulik  <rodo@ximian.com>

        * object.c (mono_ldstr): swap bytes here, it's probably not the
        best place, but works for me now, I'll redo it once I know mono
        better, also note that I add PROT_WRITE and don't reset back, also
        note that it's only affects big endians, so x86 should be OK

        * mono-endian.h (read16): use just glib macros for both endians

        * mono-endian.c: removed as glib macros are used in in
        mono-endian.h so we don't need to care about endianess for read
        macros as glib does that for us already

Thu Nov 29 18:20:58 CET 2001 Paolo Molaro <lupus@ximian.com>

        * class.h, class.h: take minimum alignment into consideration so
        that the fields of a class remain aligned also when in an array.

Tue Nov 27 16:39:01 CET 2001 Paolo Molaro <lupus@ximian.com>

        * loader.h, loader.c: add mono_method_get_param_names().

        * threads.c: New file that handles System.Threading on all platforms

        * object.c: 
        * object.h: Remove the synchronisation struct from MonoObject,
        replace it with a pointer that gets initialised on demand

        * Makefile.am: Replace all the system-specific threading code with
        a single file that uses the new wrapper library

Mon Nov 19 11:37:14 CET 2001 Paolo Molaro <lupus@ximian.com>

        * class.c, class.h: add mono_install_trampoline() so that the runtime
        can register a function to create a trampoline: removes the ugly
        requirement that a runtime needed to export arch_create_jit_trampoline.
        * object.h, object.c: added mono_install_handler() so that the runtime
        can install an handler for exceptions generated in C code (with
        mono_raise_exception()). Added C struct for System.Delegate.
        * pedump.c: removed arch_create_jit_trampoline.
        * reflection.c: some cleanups to allow registering user strings and
        later getting a token for methodrefs and fieldrefs before the assembly
        is built.
        * row-indexes.h: updates and fixes from the new ECMA specs.

Thu Nov 15 17:44:49 CET 2001 Paolo Molaro <lupus@ximian.com>

        reflection image writing.
        * reflection.c: init call convention byte to 0 in method signature.
        Encode the property signature. Don't output property-related methods
        twice. Really process the properties for a type (don't cast a field to
        a property, my mom always told me that).
        Fix 64 bit issues in pointer alignment in a different and more
        readable way.

        contains pointers into the vtable - this is more efficient for the jit

2001-10-12  Dietmar Maurer  <dietmar@ximian.com>

        Provide macros to do the interesting things on arrays in a portable way.
        * threads-pthread.c: updates for the API changes and #include <sched.h>
        (required for sched_yield()).

        fundamental MonoTypes when the class represents a
        fundamental type (System.Int32, ...).
        The TypeHandle return by ldtoken is a MonoType*.
        * icall.c: ves_icall_get_data_chunk () write out all the

        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

        * 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);

2001-08-14  Dietmar Maurer  <dietmar@ximian.com>

        * metadata.c (mono_metadata_parse_mh): fixxed pinned/byref value

2001-08-09  Dietmar Maurer  <dietmar@ximian.com>

        * image.c (do_mono_image_open): added a cache for arrays.

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).

2001-08-01  Dietmar Maurer  <dietmar@ximian.com>

        * image.h (MONO_IMAGE_IS_CORLIB): new macro to check root image

        * assembly.h (CORLIB_NAME): set to corlib.dll

        * assembly.c (mono_assembly_open): replaced strcmp() with !strcmp()

Tue Jul 31 17:54:02 CEST 2001 Paolo Molaro <lupus@ximian.com>

        * metadata.h, metadata.c, Makefile.am, private.h, assembly.c, blob.h,
        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.

Sun Jul 15 19:39:06 CEST 2001 Paolo Molaro <lupus@ximian.com>

        * 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>

        * assembly.c: g_free(ii->cli_sections) (and avoid double free of
        cli_section_tables).

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.
        (load_section_tables): Load the sections.

        * mono/metadata/metadata.c (mono_metadata_locate_token,
        mono_metadata_locate): Functions to locate the information
        definition given a token or a table and an index.
        (mono_metadata_compute_table_bases): New.
        (compute_size): New function to compute the sizes of the various
        tables.

        * mono/metadata/metadata.h: Finish listing the different index
        types. 

        * mono/metadata/pedump.c: Improve to dump new information.

2001-06-19  Miguel de Icaza  <miguel@ximian.com>

        * mono/metadata/metadata.c: Entered all the tables matching
        Beta2. 

        * mono/metadata/assembly.c (load_metadata_ptrs): Fix for Beta2
