b9a27679ec Revert "Cleanups after we dropped mem vtables"
This reverts commit 627854fee1fde93e01f27655b00a9082348ee15f.

It has been argued that not aborting on malloc() failure is
an incompatible change.

c90f283be3 Speed up g_dataset_id_dup_data
This code is used in the property notification path, so it
better be fast. This commit removes a g_return_if_fail check and
treats the common case of just a single data element better.

59df5440f3 Drop g_slice_set_config tests
With g_quark_init, we are now calling GSlice from a constructor
(this was already the case when linking against gobject).

627854fee1 Cleanups after we dropped mem vtables
Since g_malloc is now always malloc, we can just use
strdup and strndup directly.

97a25d1203 Optimize g_unichar_iswide
Apply the same optimization that was done for g_unichar_get_script
long ago: Use a quick check for the low end, and then remember the
midpoint of the last bsearch, since we're likely to be called for
characters that are close to each other.

This change made g_unichar_iswide disappear from profiles of the
gtk3-demo listbox example.

96675446c5 Make g_strerror() do less work
Store the (translated, UTF-8-encoded) error strings in a hash table to
avoid doing translation and (possibly) g_locale_to_utf8() in every
g_strerror() call.

19eb511ba4 More g_strerror() fixes
Add a check to configure.ac for strerror_r, since we don't currently
require POSIX.1-2001 conformance in general. Add back a
plain-strerror() case as a fallback, and rearrange the glibc-vs-POSIX
strerror_r() branches.

Update the docs to not claim that "not all platforms support the
strerror() function" (we require C90), but still mention the UTF-8 and
always-valid-string benefits. (And make test_strerror() check that
last part.)

23229bfd0c GString: Avoid some repeated parameter checking
Many of the append and prepend variants are just thin wrappers

b963565125 Unrolled implementation of g_utf8_to_ucs4_fast()
Unrolling the branches and expressions for all expected cases
of UTF-8 sequences facilitates the work of both an optimizing compiler
and the branch prediction logic in the CPU. This speeds up decoding
noticeably on text composed primarily of longer sequences.

3188b8ee79 Optimized branching in g_utf8_validate()
The number of branches and logical operations can be reduced by
never producing a resulting wide character value to check its range.
Instead, individual bytes in the sequence are validated
depending on the branch taken on the basis of preceding bytes.
The syntax given in RFC 3629 is made use of.

041e77249a Cleanup and Enhance the MSVC Project Generation
Make use of the common autotools module that is used to generate the MSVC
project files from their respective templates so that the main build files
beccome cleaner, and enhance them in a way that the headers that should be
installed can be written to the property sheets during 'make dist', so that
the chances of missing headers for MSVC builds can be greatly reduced.

Also use this autotools module to fill in the projects for
glib-compile-schemas and glib-compile-resources.

367f36d630 gtestutils: forbid having two tests with the same full path
In the same way that gtestutils used to let you create multiple suites
with the same name, it also let you create multiple tests with the
same name. Make that an error instead (and fix glib/tests/base64.c,
which was registering three separate tests named
"/base64/incremental/nobreak/4", and glib/tests/autoptr.c, which was
running test_g_variant_builder() twice).

123ea70d74 gtestutils: improve non-TAP output, fix handling of incomplete tests
In non-TAP mode, tests that used g_test_skip() were labelled "OK", and
tests that used g_test_incomplete() were labelled "FAIL". Explicitly
show them as "SKIP" and "TODO" instead, like in the TAP case.

Also, incomplete/TODO tests are not supposed to be treated as
failures, so fix that too.

6e382208f7 gtestutils: print the TAP test plan first, not last
TAP allows you to print the "test plan" (ie, the expected number of
tests" either at the start or the end of the test program, but if you
put it at the end, and the program crashes, automake will complain
"missing test plan", which is confusing to users (particularly since
it prints that *before* it prints that the test program crashed,
suggesting that somehow the lack of test plan was responsible for the
crash or something, rather than vice versa).

Anyway, change it to count the tests ahead of time, and print the test
plan first. Keeping this simple requires disallowing the '-p', '-s',
and '--GTestSkipCount' options when using '--tap' (although we were
already printing the wrong number in the --GTestSkipCount case
anyway).

compatibility, meaning we need to handle the "-p" case differently
from the non-"-p" case).

5a642651c7 gmessages: Mention g_return_if_fail() in g_warning() and g_error() docs
It seems to be common for people to use g_warning() or g_error() as pre-
and post-condition error reporting functions, which is not really what
they’re intended for. Similarly, it is generally a sign of bad API
design to use g_warning() to report errors — use GError instead.

Try and suggest this to the user in the hope that nice code results.

db8455f07d gmain: Document memory management best practices for GSources
It’s very common to see code where a timeout is scheduled using
g_timeout_add(), yet the owning object could be destroyed shortly
afterwards, before the timeout is fired, leading to use-after-free.

Try and prevent this happening with new code by documenting best
practices for memory management of user data for GSource callbacks.

The memory vtables no longer work, because glib contructors are called
