4 This is GLib version @GLIB_VERSION@. GLib is the low-level core
5 library that forms the basis for projects such as GTK+ and GNOME. It
6 provides data structure handling for C, portability wrappers, and
7 interfaces for such runtime functionality as an event loop, threads,
8 dynamic loading, and an object system.

30 * The functions g_snprintf() and g_vsnprintf() have been removed from
31 the gprintf.h header, since they are already declared in glib.h. This
32 doesn't break documented use of gprintf.h, but people have been known
33 to include gprintf.h without including glib.h.
35 * The Unicode support has been updated to Unicode 4.1. This adds several
36 new members to the GUnicodeBreakType enumeration.
38 Notes about GLib 2.6.0
39 ======================
41 * GLib 2.6 introduces the concept of 'GLib filename encoding', which is the
42 on-disk encoding on Unix, but UTF-8 on Windows. All GLib functions
43 returning or accepting pathnames have been changed to expect
44 filenames in this encoding, and the common POSIX functions dealing
45 with pathnames have been wrapped. These wrappers are declared in the
46 header <glib/gstdio.h> which must be included explicitly; it is not
47 included through <glib.h>.
49 On current (NT-based) Windows versions, where the on-disk file names
50 are Unicode, these wrappers use the wide-character API in the C
51 library. Thus applications can handle file names containing any
52 Unicode characters through GLib's own API and its POSIX wrappers,
53 not just file names restricted to characters in the system codepage.
55 To keep binary compatibility with applications compiled against
56 older versions of GLib, the Windows DLL still provides entry points
57 with the old semantics using the old names, and applications
58 compiled against GLib 2.6 will actually use new names for the
59 functions. This is transparent to the programmer.
61 When compiling against GLib 2.6, applications intended to be
62 portable to Windows must take the UTF-8 file name encoding into
63 consideration, and use the gstdio wrappers to access files whose
64 names have been constructed from strings returned from GLib.
66 * Likewise, g_get_user_name() and g_get_real_name() have been changed
67 to return UTF-8 on Windows, while keeping the old semantics for
68 applications compiled against older versions of GLib.
70 * The GLib uses an '_' prefix to indicate private symbols that
71 must not be used by applications. On some platforms, symbols beginning
72 with prefixes such as _g will be exported from the library, on others not.
73 In no case can applications use these private symbols. In addition to that,
74 GLib+ 2.6 makes several symbols private which were not in any installed
75 header files and were never intended to be exported.
77 * To reduce code size and improve efficiency, GLib, when compiled
78 with the GNU toolchain, has separate internal and external entry
79 points for exported functions. The internal names, which begin with
80 IA__, may be seen when debugging a GLib program.
82 * On Windows, GLib no longer opens a console window when printing
83 warning messages if stdout or stderr are invalid, as they are in
84 "Windows subsystem" (GUI) applications. Simply redirect stdout or
85 stderr if you need to see them.
87 * The child watch functionality tends to reveal a bug in many
88 thread implementations (in particular the older LinuxThreads
89 implementation on Linux) where it's not possible to call waitpid()
90 for a child created in a different thread. For this reason, for
91 maximum portability, you should structure your code to fork all
92 child processes that you want to wait for from the main thread.
94 * A problem was recently discovered with g_signal_connect_object();
95 it doesn't actually disconnect the signal handler once the object being
96 connected to dies, just disables it. See the API docs for the function
97 for further details and the correct workaround that will continue to
98 work with future versions of GLib.
103 Bugs should be reported to the GNOME bug tracking system.
104 (http://bugzilla.gnome.org, product glib.) You will need
105 to create an account for yourself.
107 In the bug report please include:
109 * Information about your system. For instance:
111 - What operating system and version
112 - For Linux, what version of the C library
114 And anything else you think is relevant.
116 * How to reproduce the bug.
118 If you can reproduce it with one of the test programs that are built
119 in the tests/ subdirectory, that will be most convenient. Otherwise,
120 please include a short test program that exhibits the behavior.
121 As a last resort, you can also provide a pointer to a larger piece
122 of software that can be downloaded.
124 * If the bug was a crash, the exact text that was printed out
125 when the crash occured.
127 * Further information such as stack traces may be useful, but
133 Patches should also be submitted to bugzilla.gnome.org. If the
134 patch fixes an existing bug, add the patch as an attachment
137 Otherwise, enter a new bug report that describes the patch,
138 and attach the patch to that bug report.
140 Bug reports containing patches should include the PATCH keyword
141 in their keyword fields. If the patch adds to or changes the GLib
142 programming interface, the API keyword should also be included.
144 Patches should be in unified diff form. (The -u option to GNU
