Make g_byte_array_new() and g_byte_array_new_take() introspectable by adding
missing transfer annotations to return value.
Covered by tests in PyGObject.
Also, remove previous comments about sort stability in g_array_sort docs,
as the method that was explained does not work. Adds a new comment
about this.

Like GPtrArray has a "free function" that can be used to free memory
associated to each pointer in the array, GArray would benefit from
having a "clear function" that can be used to clear the content of
each element of the array when it's removed, or when the entire array
is freed.
https://bugzilla.gnome.org/show_bug.cgi?id=667243
This is particular useful for:
g_array_new (sizeof (MyStruct), FALSE, FALSE);
because the correct incantation is
g_array_new (FALSE, FALSE, sizeof (MyStruct));
and these warnings will trigger in the first situation.
foo_free is conceptually "worth" one unref; not decrementing the
refcount here means the GArray or GPtrArray wrapper (but not its
contents) would leak in the following call sequence:
p = g_ptr_array_new ();
g_ptr_array_ref (p);
g_ptr_array_free (p, TRUE);
g_ptr_array_unref (p);

Depending how the array is freed, we may want to free the underlying
array (the "segment"), the struct wrapper or both.

* Represents an immutable reference counted block of memory.
* This is basically the internal glib GBuffer structure exposed,
renamed, and with some additional capabilities.
* The GBytes name comes from python3's immutable 'bytes' type
* GBytes can be safely used as keys in hash tables, and have
functions for doing so: g_bytes_hash, g_bytes_equal
* GByteArray is a mutable form of GBytes, and vice versa. There
are functions for converting from one to the other efficiently:
g_bytes_unref_to_array() and g_byte_array_free_to_bytes()
* Adds g_byte_array_new_take() to support above functions

Thanks to Sebastian Dröge for pointing out there's more than
g_array_sort() and I hadn't in fact added the comment to g_array_sort()
in 80928ea403cfff5ffaa4bc73e84e3d4ebcb09123
Fixes: Bug 599197 - array ref and unref functions crash on NULL
array.
* garray.c: Added safety guards to all public functions, which did
not have them earlier. Now when NULL is passed to them, they will
issue a warning and return, instead of segfaulting.
Fixes: Bug 568760 - nautilus freezes due to a bug in garray.c:322
* glib/garray.c: increase the size of potential return values by
using an unsigned result; properly check if we still handle valid size
proposals, return the original request if there's no usable size left
* tests/array-test.c: reproduce the error condition of the bug report
glib/pcre/pcre_ucp_search_funcs.c, glib/pcre/pcre_valid_utf8.c: add
back missing config.h includes, and this time add them to the copies
in glib/update-pcre/ too so they don't get lost again on the next PCRE
update.
glib/garray.c, glib/gbase64.c: fix signed/unsigned pointer casts

* glib/gslice.c: honour g_mem_gc_friendly settings when freeing
slices, make sure g_mem_gc_friendly is properly initialized.
* gmem.[hc]: ensure g_mem_gc_friendly is initialized from G_DEBUG upon
the first allocation. applied some branching optimizations.
* docs/macros.txt: reflected --enable-gc-friendly change and
described ENABLE_GC_FRIENDLY_DEFAULT as well as G_DEBUG=gc-friendly.
* configure.in: changed --enable-gc-friendly=yes to define
ENABLE_GC_FRIENDLY_DEFAULT.
* glib/garray.c: changed ENABLE_GC_FRIENDLY macro #ifdef-s to
if (G_UNLIKELY (g_mem_gc_friendly)).

Tue Nov 1 16:24:20 2005 Tim Janik <timj@imendio.com>
* glib/gmem.[hc]: prepared deprecation of GMemChunk and GAllocator.
added g_slice_*() API to allocate and cache small bits of memory.
an actuall allocator implementation for g_slice_*() is still pending.
* glib/gthread.[hc]: changes from a patch by Matthias Clasen.
changed GRealThread list to use in-structure *next; fields instead
of GSList, in order for thread iteration to not depenend on g_slice_*()
indirectly.
_g_thread_mem_private_get():
_g_thread_mem_private_set(): added accessors for private memory,
needed because the ordinary GPrivate implementation relies on GArray
and GSList and therefore indirectly on working g_slice_*() allocations.
* glib/gthread.[hc]:
g_thread_foreach(): new public API function to loop over all existing threads.

be used for poll rec lists.
* glib/grel.c: removed mem chunk usage, and allocated tuples via g_slice_*().
g_relation_destroy(): free all tuples from the all_tuples hash table,
this effectively maintains the life time track keeping of tuples.
g_relation_delete_tuple(): free tuples which are removed from the
all_tuples hash table. this fixes a temporary leak that was present
in the memchunk code until the destruction of the relation.

* gfileutils.[ch] (g_file_get_contents): Make length
out parameter 'gsize *len'.
* ghook.c (g_hook_compare_ids): Don't compare a
and b as 'a - b'.
* gmacros.h (GSIZE_TO_POINTER): Add GPOINTER_TO_SIZE,
GSIZE_TO_POINTER.
* gmain.c (g_timeout_prepare): Rewrite to avoid
overflows. (Fixes bug when system clock skews
backwards more than 24 days.)
* gmarkup.[ch]: Make lengths passed to callbacks
gsize, length for g_markup_parse-context_parse(),
g_markup_escape_text() gssize.
* gmessages.[ch] (g_printf_string_upper_bound): Change
return value to gsize.
* gmessages.c (printf_string_upper_bound): Remove
a ridiculous use of 'inline' on a 300 line function.
* gstring.[ch]: Represent size of string as a gsize,
not gint. Make parameters to functions take gsize,
or gssize where -1 is allowed.
* gstring.c (g_string_erase): Make
g_string_erase (string, pos, -1) a synonym for
g_string_truncate for consistency with other G*
APIs.
* gstrfuncs.[ch]: Make all functions taking a string
length, take a gsize, or gssize if -1 is allowed.
(g_strstr_len, g_strrstr_len). Also fix some boundary
conditions in g_str[r]str[_len].
* gutf8.c tests/unicode-encoding.c: Make parameters that
are byte lengths gsize, gssize as appropriate. Make
character offsets, other counts, glong.
* gasyncqueue.c gcompletion.c
timeloop.c timeloop-basic.c gutils.c gspawn.c.
Small 64 bit cleanliness fixups.
* glist.c (g_list_sort2, g_list_sort_real): Fix functions
that should have been static.
* gdate.c (g_date_fill_parse_tokens): Fix extra
declaration that was shadowing another.
* tests/module-test.c: Include string.h
Mon Jun 18 15:43:29 2001 Owen Taylor <otaylor@redhat.com>
* gutf8.c (g_get_charset): Make argument
G_CONST_RETURN char **.
2001-05-23 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* garray.c (g_array_remove_index_fast): Tiny speed improvement
suggested by noon@users.sourceforge.net.

glib/tmpl/arrays_byte.sgml: Corrected documentation for the
..._sized_new functions. Discovered by noon@users.sourceforge.net.
Wed Mar 7 09:36:33 2001 Tim Janik <timj@gtk.org>
* gboxed.[hc]: changed prototype of g_boxed_type_register_static()
to contain an optional init function and a hint at whether the
boxed structure uses ref counting internally.
added g_value_set_boxed_take_ownership().
made G_TYPE_BOXED an abstract value type.
* genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value
types.
* glib-genmarshal.c: argument type changes, preparation for third-party
arg specification.
* gobject.[hc]: cleaned up get/set property code.
added g_strdup_value_contents() to improve warnings.
* gparam.[hc]: added g_param_value_convert(), taking over responsibility
of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so
validation alterations may be valid a part of the property setting
process.
* gparamspecs.[hc]: made value comparisons stable (for sort applications).
added GParamSpecValueArray, a param spec for value arrays and
GParamSpecClosure. nuked the value exchange functions and
GParamSpecCCallback.
* gtype.[hc]: catch unintialized usages of the type system with
g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT
to flag types that introduce a value table, but can't be used for
g_value_init(). cleaned up reserved type ids.
* gvalue.[hc]: code cleanups and saner checking.
nuked the value exchange API. implemented value transformations, we
can't really "convert" values, rather transforms are an anylogy to
C casts, real conversions need a param spec for validation, which is
why g_param_value_convert() does real conversions now.
* gvaluearray.[hc]: new files that implement a GValueArray, a struct
that can hold inhomogeneous arrays of value (to that extend that it
also allowes undefined values, i.e. G_VALUE_TYPE(value)==0).
this is exposed to the type system as a boxed type.
* gvaluetransform.c: new file implementing most of the former value
exchange functions as single-sided transformations.
* gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added
g_value_set_string_take_ownership().
* *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/.
* *.[hc]: many fixes and cleanups.
* many warning improvements.
Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org>
* gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS
into G_VALUE_LCOPY(), this needs proper documenting.
* gparam.c: fixed G_PARAM_USER_MASK.
* gtype.c (type_data_make_W):
(type_data_last_unref_Wm): fixed invalid memory freeing.
* gobject.c (g_object_last_unref): destroy signal handlers associated
with object, right before finalization.
* gsignal.c (g_signal_parse_name): catch destroyed nodes or signals
that don't actually support details.
* gobject.[hc]: got rid of property trailers. nuked GObject
properties "data" and the "signal" variants.
(g_object_connect): new convenience function to do multiple
signal connections at once.
(g_object_disconnect): likewise, for disconnections.
* gparam.[hc] (g_param_spec_pool_lookup): took out trailer support.
* gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer()
as private (the latter got renamed from g_value_get_as_pointer()).
Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org>
* glib-object.h: add gvaluearray.h.
* gstring.[hc]: fixup naming of g_string_sprint*.
* gtypes.h: fixed GCompareDataFunc naming.
Wed Mar 7 09:33:27 2001 Tim Janik <timj@gtk.org>
* gobject/Makefile.am: shuffled rules to avoid excessive
rebuilds.
* gobject/gobject-sections.txt: updates.
* gobject/tmpl/*: bunch of updates, added another patch
from Eric Lemings <eric.b.lemings@lmco.com>.
2000-12-19 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gslist.c, glist.c: Ok, I'm a moron. When I originally
implemented ENABLE_GC_FRIENDLY, I forgot to include config.h into
the affected files. Now that Alex did that for those two,
inevitable typos surfaced, which are now fixed.
* garray.c, ghash.c, gqueue.c, gtree.c: Include config.h as well,
as ENABLE_GC_FRIENDLY should be known.
Mon Nov 20 18:55:17 2000 Jonathan Blandford <jrb@redhat.com>
* gtree.[hc]: Patch from David Benson <daveb@idealab.com> to add
user_data support to gtree functions.
Mon Nov 13 18:35:52 2000 Jonathan Blandford <jrb@redhat.com>
* gtypes.h (GCompareFuncData): new func type to let you use user
data when comparing nodes.
* gslist.c (g_list_sort_with_data): new function to sort with
user_data.
* glist.c (g_list_sort_with_data): new function to sort with
user_data.
* garray.[ch]: Added convenience functions to sort arrays.
* glib.h:
* garray.c: (g_array_free), (g_ptr_array_free),
(g_byte_array_free): Return the data left behind.
* gstring.c: (g_string_free): Return the data left behind.
Changed the free calls that leave data behind so they
return a pointer to the left-behind data, NULL if told not
to leave anything behind. This makes these calls easier
to use correctly, without any incompatible API change for
callers that don't know about the return value. Of course,
it would be even clearer if the free calls weren't dual-purpose
in the first place.
Wed Jul 26 12:59:31 2000 Tim Janik <timj@gtk.org>
* *.[hc]: applied patch from Andreas Persenius <ndap@swipnet.se> that
