This will allow using this class in the library code too.
No real changes yet, this is a pure refactoring.
This commit is best viewed using git --color-moved option.
Overlong (and hence invalid) 4-byte encoding was used for this character
instead of the correct 3-byte 0xEF 0xBF 0xBF sequence.
Fix this by using 3 bytes for the code points up to 0xFFFF included,
instead of excluding it as was done before.
Closes#17920.
This allows to immediately see which of the tests failed just looking at
the logs instead of having to check the failure line number manually.
No real changes.
This commit refactors the overloads of cMB2WC() and cWC2MB() methods
taking raw pointers and buffers to reuse the same code and fixes the
wrong length of the buffer returned by cWC2MB(wchar_t*) overload for
conversions using multiple bytes to represent the NUL terminator
character (it previously was wrong for UTF-16 and UTF-32 conversions due
to wrongly subtracting 1 from the length when creating it instead of
correctly subtracting GetMBNulLen()) and the wrong length of the buffer
returned from cMB2WC(char*) overload where no adjustment for the
trailing NUL was done at all.
Also return simple default-constructed buffers from these methods in
case of failure instead of using wxScopedCharBuffer::CreateNonOwned()
which is less obvious and less efficient (even if the latter probably
doesn't matter here because it's only done in case of an error).
Finally, add tests checking that using WC2MB() or either of cWC2MB()
overloads returns the buffers of the same length and with the same
contents.
Drop the legacy CppUnit testing framework used for the unit tests.
Replacing it with Catch has the advantage of not requiring CppUnit
libraries to be installed on the system in order to be able to run
tests (Catch is header-only and a copy of it is now included in the
main repository itself) and, in the future, of being able to write
the tests in a much more natural way.
For now, however, avoid changing the existing tests code as much as
[reasonably] possible to avoid introducing bugs in them and provide
the CppUnit compatibility macros in the new wx/catch_cppunit.h header
which allow to preserve the 99% of the existing code unchanged. Some
of the required changes are:
- Decompose asserts using "a && b" conditions into multiple asserts
checking "a" and "b" independently. This would have been better
even with CppUnit (to know which part of condition exactly failed)
and is required with Catch.
- Use extra parentheses around such conditions when they can't be
easily decomposed in the arrays test, due to the use of macros.
This is not ideal from the point of view of messages given when
the tests fail but will do for now.
- Rewrite asserts using "a || b" as a combination of condition
checks and assert macros. Again, this is better anyhow, and is
required with Catch. Incidentally, this allowed to fix a bug in
the "exec" unit test which didn't leave enough time for the new
process to be launched before trying to kill it.
- Remove multiple CPPUNIT_TEST_SUITE_NAMED_REGISTRATION() macros,
our emulation of this macro can be used only once.
- Provide string conversions using Catch-specific StringMaker for
a couple of types.
- Replace custom wxImage comparison with a Catch-specific matcher
class.
- Remove most of test running logic from test.cpp, in particular don't
parse command line ourselves any longer but use Catch built-in
command line parser. This is a source of a minor regression:
previously, both "Foo" and "FooTestCase" could be used as the name of
the test to run, but now only the latter is accepted.
After the fixes in the previous commits conversions between wchar_t containing
surrogates and UTF-{8,16,32} work correctly, so add a test ensuring that this
is the case.
Notice that other conversions are still broken in presence of surrogates.
See #17070.
UTF-32 conversions use a useful optimization by avoiding the extra scan of the
input wchar_t string in their FromWChar() and cWC2MB() implementation when
they are only asked to compute the required buffer size without actually doing
the conversion. However this means that for an input string containing UTF-16
surrogates (which is possible under MSW where wchar_t is 16 bits) the actual
size of the output string can be smaller than that returned by FromWChar(NULL).
Document that this may happen and avoid relying on the exact equality in the
tests.
See #17070.
Correctly fail if the wide string being converted is UTF-16 encoded (which can
only happen on platforms using 16 bit wchar_t, i.e. MSW) and ends in the
middle of a surrogate pair.
Notice that other conversions still wrongly encode invalid wchar_t sequences
such as 0xd800 not followed by anything, this will need to be fixed in the
future, but for now at least make it work for the most commonly used
conversion.
See #17070.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.

Disable unit tests involving operations (such as conversions between UTF and
anything but plain ASCII) not available in ANSI build.
This fixes the test suite for non-Unicode build under Unix.

Don't assign wxNO_LEN to int variable, this results in gcc warnings about
overflow in implicit constant conversion.
Use size_t for the variable containing string length to fix it.

This test fails for MinGW, probably because its CRT doesn't use the same
locale names as MSVC CRT. Just disable it for now, as it was already disabled
for non-MSW platforms.
Also use LocaleSetter class (extracted from CLocaleSetter) to change the
locale for this test duration only to avoid affecting any tests running after
it.

Remove unnecessary casts and initialize the variable with its contents
directly instead of using strange looking wxWCharBuffer ctor from size_t (even
if it did work, it was unnecessary).

We didn't handle the case when the length of the input buffer was not
specified correctly and wxConvAuto::DetectBOM() could read beyond the end of
input. Moreover, the unit test actually relied on this as it didn't pass the
correct length for the literal strings with embedded NULs. This somehow worked
with MSVC but failed with MinGW (see #10713).
Correct the code to handle wxNO_LEN case correctly and fix the unit test to
pass the correct lengths.

wxWidgets requires wchar_t for some time now; wx/chartype.h has a check
to fail complation without it. Simplify code by removing now-dead code
for the !wxUSE_WCHAR_T case.

wxConvAuto implicitly supposed that the chunk of data passed to it for
translation was big enough to allow it to at least detect the BOM from it.
However this isn't necessarily the case and never is with wxTextInputStream
which reads the bytes one by one.
Fix this by waiting until we have enough data to be able to detect the BOM.
This still doesn't fix the problem with streams without BOM and the
corresponding unit test still fails -- it will need to be fixed at the level
of wxTextInputStream itself later but handling correctly the cases when a BOM
is present is already better than before.
See #11570.

The variable "lenChunk" was incorrectly used as the length of the wide string
chunk which could result in wrong output.
Worse, the output buffer could be overflown for the final chunk because it
didn't have to have enough space for the trailing NUL(s) in it.
Fix both bugs and added unit tests for them.
Based on patch by Kuang-che Wu.
Closes#11486.
