Wed Jun 20 12:00:54 2001 Owen Taylor <otaylor@redhat.com>
Changes for 64-bit cleanliness, loosely based on patch
from Mark Murnane.
* gconvert.c (g_convert/g_convert_with_fallback): Remove
workarounds for since-fixed GNU libc bugs. Minor
doc fix.
* gconvert.[ch]: Change gint to gsize/gssize as
appropriate.
* gconvert.c (g_locale/filename_to/from_utf8): Fix incorrect
computation of bytes_read / bytes_written.
* 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 **.
