It was documented before, but wasn’t especially clear. Doing
if (X)
g_free (X);
is apparently quite a pervasive real-world anti-pattern, so perhaps it
could be documented more explicitly.

Just in case people have forgotten their basic algorithms course. Seen
in some pretty terrible code in the wild; hopefully mentioning the cost
in the documentation will make people think twice about using a counter
variable when iterating over a linked list.

It’s quite common to see a g_param_spec_pointer() used for GObject or
boxed types which, while not incorrect, does make memory management
unsafe, since no copying or reference counting can be performed
automatically.
Similarly, people often use g_param_spec_boolean() when an enum would be
more appropriate, cf.
http://blog.ometer.com/2011/01/20/boolean-parameters-are-wrong/
Using enums also means that the set of allowable values can be extended
in future if needed.
In the hope that people who write code like that read the documentation,
mention the more specific types in the documentation.

It’s NULL iff free_segment is TRUE, so the annotation doesn’t quite
capture all the function definition, but is a safe over-estimate of the
return value’s nullability.

Link to zlib1.lib for all builds, as:
-The notion of zlib1d.lib is rather not standardized across the board for
most cases.
-Easier for the grand all-in-one solution file.
Use the /MP option so that each project can build multiple sources in
parallel, which can cut down release build times by quite a bit. This will
cause a brief warning for debug builds due to their use of /Gm, and builds
would otherwise proceed as they did before.
Unfortunately Visual Studio 2008 is too old to support the /d2Zi+ flag, so
we can't make a better debug situation for it at the moment.
Use Multiprocessor compilation which can cut down build times by quite a
bit and use the /d2Zi+ flag to have better debugging info being logged to
the .pdb for release builds.
These are only applicable for Visual Studio 2010/2012 and later.
There was a theoretical deadlock between the worker trying to emit a
signal at the same time as we were waiting for it to shutdown the
notification (while holding the lock).
The deadlock was particularly annoying because we didn't really need to
wait for the shutdown and because it wasn't possible to signals to
arrive while waiting for a start. Attempting to deal with start and
stop in an asymmetric way could have lead to other weird situations,
however.
Drop the lock while waiting for the worker thread to start. This means
that we face the possibility of multiple waiters on the cond at the same
time, so we need to make more of a state machine.

GUnixMountMonitor was not threadsafe before. It was a global singleton
which emitted signals in the first thread that happened to construct it.
Move it to a per-context singleton model where each GMainContext gets
its own GUnixMountMonitor. Monitor for the changes from the GLib worker
thread and dispatch the results to each context with an active monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=742599
Deprecate g_unix_mount_monitor_set_rate_limit() and turn it into a
no-op.
This function doesn't behave as advertised. It only controls rate
limiting for filesystem-based monitors. It has no impact over reporting
mount changes on Linux, for example, because those are based on polling
for changes in /proc (which doesn't use filesystem monitors). It also
has no impact on Mac OS because a library interface is used there.
This was added in https://bugzilla.gnome.org/show_bug.cgi?id=521946 in
order to be used by HAL, which is effectively dead. udisks no longer
uses this code at all.
https://bugzilla.gnome.org/show_bug.cgi?id=742599
This is a singleton, but we have a function called _new() to get it.
What's worse is that the documentation makes no mention of this, and
actually specifically says that a new monitor will be created each time.
https://bugzilla.gnome.org/show_bug.cgi?id=742599
Add a new internal helper called GContextSpecificGroup.
This is a mechanism for helping to maintain a group of context-specific
monitor objects (eg: GAppInfoMonitor, GUnixMountMonitor).

If someone explicitly calls g_application_quit() then don't attempt to
drain the mainloop of remaining sources.
This allows applications with 100% CPU utilisation to quit reliably.

We install win32-software/autorun.exe (as test data for mime scanning)
only on UNIX builds, so don't attempt to chmod it on 'make install'
unless we're on UNIX.
This is pure read-only access to an external struct
so void warnings for people calling it from const

switching to the old macros boilerplate to G_DECLARE_*
a lot of warnings start to pop when *_IS_A_* or such are
called from a const context.

I love Emacs keyboard macros, used them to convert the list of
defines cleverly into a list of tests, then iterated and filled in
the necessary constructor arguments.
- It's not sufficient, there are other bare array types
like guint8, gdouble, etc.
- Other types like GVariant* always come as pointers, whereas
there's a rather fundamental distinction between "gchar" and
"gchar*" that has been signified to C programmers for 30+ years via
the '*' character, and we're hiding that.
https://bugzilla.gnome.org/show_bug.cgi?id=744747
The g_autoptr() being associated with the type name works out really
well for things like GHashTable. However, it's a bit more awkward to
associate with "gchar". Also because one can't use "char".
Similarly, there are a lot of other "bare primitive array" types that
one might reasonably use.
This patch does not remove the autoptr for "gchar", even though I
think it's rather awkward and strange.
Also while we're here, add a test case for the cleanup bits.
https://bugzilla.gnome.org/show_bug.cgi?id=744747
After ::shutdown, run the mainloop until all pending activity is
handled, before returning from run().
Among other things, this gives a chance for destroyed windows to be
properly withdrawn from the windowing system.
https://bugzilla.gnome.org/show_bug.cgi?id=744876
This is *significantly* more pleasant to use from C (while handling
errors and memory cleanup).
While we're here, change some ugly, leaky code in
tests/desktop-app-info.c to use it, in addition to a test case
in tests/file.c.
