Tests may have runtime dependencies that are related to the typelib
dependencies, so we need to satify them or the tests will fail at
runtime if we're not building their prerequisite for other reasons.
That's saying that the tests are currently failing when explicitly

It’s very obviously a false positive, as `str` has been added to on the
previous line, so can’t be `(void *) 0`. Not sure what scan-build is
thinking.
I’d rather not have this assertion (it doesn’t help the programmer’s

running with no warnings so that it can helpfully catch newly-introduced

All of the indications in the surrounding code are that `node` should
never be `NULL`, but the error handling for it did actually allow it to
be `NULL` iff its `parent` was also `NULL`.
That made scan-build (kind of legitimately) warn about `NULL` pointer
dereferences of `node`.
Avoid that by unambiguously using an assertion to prevent `NULL` nodes.

scan-build thinks that the `atypes` array is leaked, but it’s not.
Ownership is transferred into the `ffi_cif` structure, and it’s

g-ir-scanner currently maps these to lower-level types at scan time by
assuming that time_t is an alias for long, off_t is an alias for size_t
and so on. This is not always accurate: some ILP32 architectures have
64-bit time_t (for Y2038 compatibility) and 64-bit off_t (for large file
support), and that mismatch is tracked as GNOME/gobject-introspection#494.
One option for resolving this g-ir-scanner bug is to have it pass these
types through to the GIR XML, and teach g-ir-compiler and its replacement
gi-compile-repository to convert them to the corresponding concrete
type tag, as they already do for abstract types such as `long long` and
`size_t`.

To avoid a big introspection API break.
These APIs are now listed in the new `{GLib,Gio}{Unix,Win32}-2.0.gir`

listed in `Gio-2.0.gir` and `GLib-2.0.gir` as well, until the next major
introspection API break (and none is planned).

For both GLib and GIO. (GObject, GIRepository and GModule don’t have any
platform specific APIs.)
This is needed for two reasons:
* If the same GIR file is shipped on multiple platforms, it has no way
to conditionally define/not-define an API based on the platform (like
an `#ifdef` in a C header). So we either end up shipping differing
GIR APIs on different platforms, or shipping a GIR file which
declares APIs which aren’t resolvable by `dlopen()` on certain
platforms, and will cause a language runtime error.
* The API reference documentation is now generated from the GIR, and
similar problems are present there: if the GIR contains different
symbols depending on the platform, there is no way to generate API
documentation for the union of all of them.
The fix is to ensure that there are no conditional symbols in a GIR, by
splitting out the platform specific symbols into platform specific GIR
files. Platform specific documentation can then be generated from these,
in addition to the main, platform agnostic, documentation.
The documentation changes will following in a subsequent commit.

Instead, add a method on `GIRegisteredTypeInfo` which indicates whether
the registered type is a boxed type. This will return true for
`GIStructInfo` and `GIUnionInfo` instances which are boxed (not all
structs and unions are).
This makes `GIBoxedInfo` redundant, and it’ll be dropped in a following
commit.
---
There are several different things which typelibs need to be able to
represent:
1. Plain old datatype (POD) structs
2. POD unions
3. Structs with a copy func and/or free func
4. Unions with a copy func and/or free func
5. Structs which are the ‘GType struct’ for an object or interface (i.e.
the class or instance or interface struct)
6. Structs with a copy func and free func *and* boxed GType
7. Unions with a copy func and free func *and* boxed GType
8. Boxed GTypes which represent something other than a struct or union
So there’s a lot going on here. In commit
e28078c70cbf4a57c7dbd39626f43f9bd2674145, a lot of this was reworked,
and support was added for boxed unions and boxed ‘others’ (the last item
on the list above).
Since then, support for boxed types other than structs seems to have
atrophied a bit, and the whole lot has got a bit confusing.
It was perhaps less confusing when all the `GIBaseInfo` subclasses were
actually aliases of each other, but now they have subtype relationships,
the position of `GIBoxedInfo` in that type hierarchy has become unclear.
How is it related to `GIStructInfo`, `GIUnionInfo` and
`GIRegisteredTypeInfo`?
Since a boxed type is necessarily a `GIRegisteredTypeInfo`, and the
methods of `GIRegisteredTypeInfo` are all written to allow a `GType` to
be optional, so that `GIStructInfo` and `GIUnionInfo` can safely derive
from it and still be used to represent plain old datatypes without
`GType`s, it makes sense to add a method to `GIRegisteredTypeInfo` to
indicate that the registered type is derived from `G_TYPE_BOXED`.
Accordingly, the things above are now represented in libgirepository’s
type system as:
1. `GIStructInfo` instance, `GIRegisteredTypeInfo` methods return no
`GType` info
2. `GIUnionInfo` instance similarly
3. `GIStructInfo` instance, `GIRegisteredTypeInfo` methods return no
`GType` info, `gi_struct_info_get_{copy,free}_function_name()` return
non-`NULL` values
4. `GIUnionInfo` instance similarly
5. `GIStructInfo` instance, `GIRegisteredTypeInfo` methods return no
`GType` info, `gi_struct_info_is_gtype_struct()` returns true
6. `GIStructInfo` instance, `GIRegisteredTypeInfo` methods return valid
`GType` information, `gi_registered_type_info_is_boxed()` returns
true, `gi_struct_info_get_{copy,free}_function_name()` return
`NULL` values (because the copy/free functions are hidden inside the
boxed type registration at runtime)
7. `GIUnionInfo` instance similarly
8. Not representable, but could be represented in future by re-adding a
`GIBoxedInfo` type which derives from `GIRegisteredTypeInfo` and is
used solely for boxed ‘other’ types, *not* boxed structs or unions

When creating `GIBaseInfo` instances from binary blobs, so far the code
has used an undocumented implicit conversion from one enum type to the
other. That’s a bit nasty, as it means the two enum types need to be
kept in sync (without that need being documented).
Introduce an explicit conversion function to make things more explicit.
Currently it does nothing, but in an upcoming commit it will be used to
deprecate a blob type.

While it’s an internal API which `girwriter.c` has access to, it’s not
available inside `libgirepository-internals.so`. This wasn’t spotted
before commit 343027d5d landed because none of the existing users of
`libgirepository-internals.so` use the relevant code in `girwriter.c`,
so it got compiled out (`libgirepository-internals.so` is statically
linked and can be optimised like this).
Now that `gi-decompile-repository` uses the relevant code from
`girwriter.c`, the problem is obvious and `gi-decompile-repository`
fails to link.
Fix that by no longer using `gi_base_info_get_info_type()` in
`girwriter.c`. These are changes which would have eventually been made

Take a GError * for typelib loading code, validate the header. This
fixes bizarre errors from gjs where g_irepository_require would happily
load old typelibs.
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).

Foreign structs are special in the sense that there might
be native bindings (for instance PyCairo for PyGI) that provides

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.
Add --all option, which is intended to show some information not
usually included in the GIR.
Currently, it shows the size of structs and unions.

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.
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.
