This reverts commit 41f6f17d01 ("return 0
(meaning the file is not seekable, as the docs now explain) instead of
4KB for the files in sysfs under Linux") as it seems to be wrong to
return a value different from what "ls -l" or "stat" return here and the
original problem was solved in a better way in the previous commit.
See #9965.
Closes#17818.
Calling this function with an unseekable file, such as any file under
/sys on Linux systems, would previously just hang as the loop condition
was never satisfied when length was -1.
Fix this by checking for this case and using a different approach by
extending the buffer we read the data into as we go instead of
preallocating it all at once.
See #9965.
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.
The typo resulted in, depending on compiler used, an error ("undeclared
identifier") or warning. Fix by using the intended name.
Regression since 5552351393.
Don't apply at best unnecessary, and actually harmful, as it uses a wrong
conversion, fn_str() when calling wxRmDir() which takes wxString.
Update unit tests to check that wxRmdir() now works with non-ASCII filenames
too.
Closes#17644.
Assert and return false instead, this is more developer-friendly.
Add unit tests to check that these functions really work as expected when
called on a closed file.
Closes#17828.
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.

Make sure we exit the loop when reading the file in chunks in
wxFile::ReadAll() and add a unit test for it to ensure that it's really
correct.

It is wrong to use dir.GetName()+"/" to obtain a slash-terminated directory
name as this results in (usually harmless but at best ugly) double slashes at
at the beginning of the string for the root directory. Add GetNameWithSep() to
obtain the correct result in all cases.

The test was intended to verify that round trip via wxFile::Write/Read()
worked even for the strings with embedded NULs but as the string wasn't
constructed correctly it didn't actually contain any NULs but was ended by the
first of them.
Fix this by using explicit length of the string as usual when dealing with
strings with embedded NULs. Also fix the conversion back to Unicode to use the
correct length.

These tests didn't work correctly in ANSI build because the conversion
parameter of wxFile::Write() isn't used there, the contents of an ANSI
wxString is always written to the file as is -- hence reading it back using
UTF-16 or UTF-32 conversion fails.
The test would need to be totally rewritten for ANSI build of wx and it
wouldn't test wxFile but rather conversion functions already tested elsewhere
so just disable it instead.
This fixes a crash (due to passing NULL pointer to memcmp()) which prevented
the test suite from running to completion in ANSI build.

"C:" drive doesn't need to exist under Windows, rely on HOMEDRIVE environment
variable defined in all recent Windows versions to get a valid drive letter
(still fall back to "C:" if the variable is not defined -- we could have use
wxFSVolume to find it then but this seems like an overkill).

fix test cases /usr//bin and /usr///bin: they succeed because wxDir::Exists does not care about redundant path separator (and this holds also for non-Unix platforms);
add some more test case

wxFileOffset and ssize_t are not the same type under this platform so using
CPPUNIT_ASSERT_EQUAL() with the arguments of these types fails. Use ssize_t
instead of wxFileOffset to fix this.

This function was broken for conversions using more than one byte per
character (e.g. UTF-16 or UTF-32) and also even for UTF-8 for strings
containing NUL bytes as it used strlen() to determine the number of bytes to
write out instead of using the really needed number.
Fix this by using the wxCharBuffer::length() method which always returns the
correct value.
Also add a wxFile unit test verifying that it can correctly read back a string
written using any of UTF-8, UTF-16 or UTF-32.
Closes#11192.
