57554d4b2d Switch to storing string form of error quarks
Instead of storing the name of the function to call to get the
error quark, store the string form of the error quark, which
we derive from the introspection binary during scanning.

Update EnumBlob and GIEnumInfo to include the new information.

This will allow determining a back-mapping from error quark
to error domain without having to dlsym() and call all the
known error quark functions.

Based on earlier patches from Owen Taylor and Maxim Ermilov.

f9ebb4e99d Deprecate ErrorDomain
The previous ErrorDomain blob was never actually scanned or used, and
it was kind of a lame API conceptually.

To keep some compatibility, rather than removing the enumeration
values, rename them to _INVALID, and don't bump the typelib version.
This should in theory allow a new libgirepository to read an old
typelib.

fef2a7b8dd Fix accessing structure fields that are arrays
We need to distinguish inline arrays inside structures, and arrays
that are pointers and annotations, and we can do it with
g_type_info_is_pointer(), setting it to FALSE for fixed size arrays.
As a side effect, (array fixed-size=N) on a pointer type has no longer
the expected result.

a0890f3d8f GIrNode: fix lookup of cached type nodes
Different types of array have different type nodes, so they should
produce different keys in the cache of already seen type nodes, to

ec76ea8628 Handle enumerations with the full range of signed and unsigned values
The C compiler will pick an enumeration type that accomodates the specified
values for the enumeration, so ignoring 64-bit enumerations, we can
have enumeration values from MININT32 to MAXUINT32. To handle this properly:

 - Use gint64 for holding eumeration values when scanning
 - Add a 'unsigned_value' bit to ValueBlob so we can distinguish the
   int32 vs. uint32 cases in the typelib
 - Change the return value of g_value_info_get_value() to gint64.

f5ec6f6698 Use GLib types consistently
Rather than have the scanner/parser handle both e.g. "glong" and
"long", simply use the GLib types everywhere.

This commit adds TYPE_LONG_LONG and TYPE_LONG_DOUBLE to the
scanner types; however, rather than add them to the typelib,
they're just marked as not-introspectable.

62f1b65cc8 [gircompiler] Clean up parsing
We never actually include multiple modules in the compiler,
so just nuke that.  Also rather than passing around GIrModule
consistently pass around a GIrTypelibBuild structure which
has various things.

This lets us maintain a stack there which we can walk for
better error messages.

Also, fix up the node lookup in giroffsets.c; previously
it didn't really handle includes correctly.  We really need to
switch to always using Foo.Bar (i.e. GIName) names internally...

3a310fd242 Don't include machine-dependent integral types in the typelib
Previously we had both e.g. GI_TYPE_TAG_LONG and GI_TYPE_TAG_INT64,
but in fact the typelib is already machine-specific, so it makes sense
to just encode this as a fixed type.  The .gir remains abstract.

We also remove size_t from the typelib; one would never want to treat
it differently than an integer.

time_t is removed as well; while bindings like gjs had special handling
to turn it into e.g. a JS Date object, I don't think we should encourage
people to use these POSIX types in their API.  Use GTimeVal or the like
instead.

Because the typelib is now really machine-specific, we need to remove
the -expected.tgirs from git.  (We could potentially add a check
which wasn't just a literal diff later)

b6d50e2951 Add support for non-GObject fundamental objects
This patch adds support for instantiable fundamental object types,
which are not GObject based. This is mostly interesting for being
able to support GstMiniObject's which are extensivly used in GStreamer.
Includes a big test case to the Everything module (inspired by
GstMiniObject) which should be used by language bindings who wishes to
test this functionallity.

This patch increases the size of the typelib and breaks compatibility
with older typelibs.

3d0dc7d214 Allow attributes on parameters and return values
Any annotation where the key has a dot in the name will go into the
attribute list. For example

  * @arg: (foo.bar baz): some arg

the parameter @arg will get the attribute with key foo.bar and value
baz. This also works for.

  * Returns: (foo.bar2 baz2): the return value

Also add tests for this new feature.

c57c9efe6f Attribute bug-fixes
Rectify an assumption that nodes are ordered according to offset
- since this assumption was not true, attributes ended up being not
ordered either and the bsearch() when looking up attributes failed
mysteriously. Instead of making such assumptions, simply sort the
list of nodes we want to extract attributes from.

The total attribute size computation was wrong as we didn't properly
descend into subnodes. This resulted in memory access violations
when writing the typelib (because not enough data was allocated).
Instead of having a separate function for this, just include the
attribute size in the existing function.

46d9ef151e Support (out caller-allocates)
People have wanted support for marking (out) on functions of the
form:

/**
 * clutter_color_from_pixel:
 * @pixel: A pixel
 * @color: (out): Color to initialize with value of @pixel
 */
void
clutter_color_from_pixel (guint32 pixel, ClutterColor *color);

Where the caller is supposed to have allocated the argument; the
C function just initializes it.  This patch adds support for this
argument passing style to introspection.  In this case, we see the
(out), and notice that there's only a single indirection (*) on
the argument, and assume that this means (out caller-allocates).

7299c89fc9 Bug 557383 - Virtual method support
Broadly speaking, this change adds the concept of <vfunc> to the .gir.
The typelib already had most of the infrastructure for virtual functions,
though there is one API addition.

The scanner assumes that any class callback slot that doesn't match
a signal name is a virtual.  In the .gir, we write out *both* the <method>
wrapper and a <vfunc>.  If we can determine an association between
them (based on the names matching, or a new Virtual: annotation),
then we notate that in the .gir.

The typelib gains an association from the vfunc to the function, if
it exists.  This will be useful for bindings since they already know
how to consume FunctionInfo.

ff6b28c17b Bug 551738 - Associate classes with their structs
Inside glibtransformer, we now look at structures ending in "Class" and
see if they have an associated GlibObject (i.e. a structure of the same
name without the "Class" suffix).  If found, pair them up.

The .gir file for <class> gains an attribute denoting its associated
class struct.  Any <record> many now have a glib:is-class-struct-for
annotation which tells which (if any) <class> for which it defines the
layout.

In the .typelib, we record the association between the class and
its structure.  Generic structures however just have a boolean
saying whether they're a class struct.  (Going from a generic class
struct to its class should not be necessary).

Finally, we expose GIRepository APIs to access both bits of information
from the .typelib.
