Contrary to what a comment in wxTextInputStream::GetChar() said, it is
actually possible to get more than one wide character from a call to
wxMBConv::ToWChar(len+1) even if a previous call to ToWChar(len) failed
to decode anything at all. This happens with wxConvAuto because it keeps
returning an error while it doesn't have enough data to determine if the
input contains a BOM or not, but then returns all the characters
examined so far at once if it turns out that there was no BOM, after
all.
The simplest case in which this created problems was just input starting
with a NUL byte as it as this could be a start of UTF-32BE BOM.
The fix consists in keeping all the bytes read but not yet decoded in
the m_lastBytes buffer and retrying to decode them during the next
GetChar() call. This implies keeping track of how much valid data is
there in m_lastBytes exactly, as we can't discard the already decoded
data immediately, but need to keep it in the buffer too, in order to
allow implementing UngetLast(). Incidentally, UngetLast() was totally
broken for UTF-16/32 input (containing NUL bytes in the middle of the
characters) before and this change fixes this as a side effect.
Also add test cases for previously failing inputs.
Ensure we don't leave "mytext.dat" and "test.txt" lying around in any
directory the tests are run from by ensuring that these files are
destroyed by the test code using them.
Initialize m_pos correctly when using an existing, and hence possibly
not empty, string (and not the internal one which is always empty
initially). The old code was totally wrong as it divided the string
length by the size of wxChar instead of multiplying by it, but doing
this could have been wrong too with UTF-16 and surrogates, so use the
conversion object to compute the real length of the string
representation in the corresponding encoding.
Add a simple unit test checking that this works as intended.
Closes#17985.
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.
Don't remove the files in the test cases classes dtors, this was
inconsistent with how they were created: we either need to create the
file in the ctor and destroy it in the dtor or do both only once
globally.
Implement the second solution using the helper AutoRemoveFile instead of
a simple static bool in GetInFileName() implementations.
Use positive tests really checking for whatever we want to check (that
the stream is not seekable in this particular case) instead of just
checking that the test fails, for whatever reason -- which might not be
at all the reason for which we expect it to fail.
It is better to use wholly non-standard wxWidgets smart pointer class
rather than using standard, but deprecated in C++17, std::auto_ptr<> as
this results in warnings from recent compilers.
It was only used as part of WXTEST_WITH_GZIP_CONDITION which was
necessary only to support running the tests on systems using zlib < 1.2
which is not a concern since many years any more, so simplify the code
by using the simple non-conditional CPPUNIT_TEST instead and drop the
helper macros which were required only for this.
This should prevent an assert failure which happens if we call Accept() on an
invalid server below and also confirm if the server creation really failed or
not.
This port is not used and is not being worked on, so remove it to reduce the
amount of the code which needs to be updated for every global change.
Also remove tests for VisualAge compiler which isn't used since ages.

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.

Allow to optionally raed/write float/double values in IEEE 754 single/double
precision formats, respectively, instead of always using the extended
precision format for both of them.
This makes the code more flexible, allowing for better interoperability with
the other programs, and also allows to implement floating point functions in
these classes even when wxUSE_APPLE_IEEE is turned off (as can be the case
because of the licencing concerns for the code in extended.c).
Closes#10625.

Don't create streams on the heap completely unnecessarily, just allocate them
on the stack. This makes the code shorter, safer and slightly more efficient.

Additionally renamed wxOSX' private wxNativePrinterDC::Ok() function to IsOk().
Didn't deprecate the various Ok() functions: given the amount of changes already introduced in 3.0 a trivial one like this seems more suitable for after 3.0.

Applied patch by snowleopard2 fixing a bunch of typos such as misspellings and double words in the documentation. Combined the patch with some local queued typos waiting to be committed as well as adding new typo fixes inspired by the patch.
Function names with American spelling were not changed nor was third-party code touched. The only code changes involve some changes in strings that are translated ("Can not" -> "Cannot").
Closes#13063 (again).

In ANSI build wxString::mb_str() returns a pointer to the internal wxString
data directly instead of a buffer with a proper length, so it provides access
to the part of the string before the first embedded NUL only.
Use To8BitData() which always returns the buffer of the correct size in all
builds.
The open question remains whether mb_str() should be changed to return a (non
owned) buffer and not just a pointer in ANSI build. This would make
manipulating strings with embedded NULs safer but mb_str() would be less
efficient and less compatible.

wxScopedCharBuffer can't be constructed from char* string, just use

We wrote an extra NUL byte to the stream and, unsurprisingly, contents of its
buffer didn't match the original string resulting in the test failure.
