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.

Documentation says about g_vfunc_get_offset():
"Obtain the offset of the function pointer in the class struct.
The value 0xFFFF indicates that the struct offset is unknown."
But g-ir-compiler did set the value to 0 when the offset is unknown.
This patch fixes it.

One of the first big changes in this rewrite is changing the Type
object to have separate target_fundamental and target_giname properties,
rather than just being strings. Previously in the scanner, it was
awful because we used heuristics around strings.
The ast.py is refactored so that not everything is a Node - that
was a rather useless abstraction. Now, only things which can have
a GIName are Node. E.g. Type and Field are no longer Node.
More things were merged from glibast.py into ast.py, since it isn't
a very useful split.
transformer.py gains more intelligence and will e.g. turn GLib.List
into a List() object earlier. The namespace processing is a lot
cleaner now; since we parse the included .girs, we know the C
prefix for each namespace, and have functions to parse both
C type names (GtkFooBar) and symbols gtk_foo_bar into their
symbols cleanly. Type resolution is much, much saner because
we know Type(target_giname=Gtk.Foo) maps to the namespace Gtk.
glibtransformer.py now just handles the XML processing from the dump,
and a few miscellaneous things.
The major heavy lifting now lives in primarytransformer.py, which
is a combination of most of annotationparser.py and half of
glibtransformer.py.
annotationparser.py now literally just parses annotations; it's
no longer in the business of e.g. guessing transfer too.
finaltransformer.py is a new file which does post-analysis for
"introspectability" mainly.
girparser.c is fixed for some introspectable=0 processing.
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.
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...
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)
https://bugzilla.gnome.org/show_bug.cgi?id=623774
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.
https://bugzilla.gnome.org/show_bug.cgi?id=568913
Moving to <doc> allows us to better preserve whitespace. XML has no
facility for whitespace-preserving attributes.
Second, for arrays and lists, both types with unknown element_type can
occur in the current scanner; it's least wrong if we write out an
<any> type.
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.

This work allows us to move closer to replacing gtk-doc, among other
things. We add a generic attribute "introspectable", and inside the
typelib compiler if we see "introspectable=no", we don't put it in the
typelib. This replaces the hackish pre-filter for varargs with a much
more generic mechanism.
The varargs is now handled in the scanner, and we emit
introspectable=no for them.
Add generic metadata to Node with references to file/line/column,
which currently comes from symbols.
Add scanner options --warn-all and --warn-error.

We need to support parsing older .girs for inclusion purposes. (But
we should probably have an explicit .gir version, and require the
attribute for newer versions)
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).
https://bugzilla.gnome.org/show_bug.cgi?id=604749
Foreign structs are special in the sense that there might
be native bindings (for instance PyCairo for PyGI) that provides
the same functionallity as the introspected variant.

Add type tags for short and ushort, plus all of the requisite code needed
to utilize them in libgirepository.

Add test functions to the everything library and the expected gir file.
gtypelib.c constant validation fixed by Colin Walters <walters@verbum.org>
When ./configure --prefix $HOME/some/where is used gobject-introspection
will happily install the files into $HOME/some/where/data/gir-1.0 but
it will refuse to find them. Apply the same trick as in
girepository/girepository.c:init_globals to find the gir files.
Unifiy the name gir-1.0 in GIR_SUFFIX and use it throughout the
project, introduce GIR_DIR which holds the path to the gir files and
update girparser and transformer.py to look into this path.
Parse the c:prefix from the .gir, include it in the header. Armed with this
information, we can now optimize lookups of GTypes because we
have the requirement that GTypes must start with the c:prefix. We do
fall back though if a lookup fails.
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.
We now support an extensible mechanism where arbitrary key-value
pairs may be associated with almost all items, including objects,
methods, and properties.
These attributes appear in both the .gir and the .typelib.
Similar to GObject class structs, we pair up GInterfaces with
their C structures.
Also, move some GLib-specific things into glibast.py, and make
the naming more generic.
When generating a .gir file, we now first parse all of our .gir includes
to pick up their <package> headers. Then, we merge that with the set of
--pkg arguments passed to us, run pkg-config to gather the arguments,
and finally save the merged pkg-config list to our new .gir file.
This is useful for software which needs to map from .gir to pkg-config
in a programmatic way.
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.

The logic in girparser.c didn't work very well if there were multiple
<namespace/> nodes within a single <repository/> (context->namespace
was always the overall filename and not the the name specified in the

be mis-prefixed in include modules.) Also check that the "name" in
the <namespace/> node matches the filename.
