.configure wrong for CPPUNIT #104

Open Barchfeld opened 2 years ago

Barchfeld commented 2 years ago

Describe the bug

I have to comment the line

PKG_CHECK_MODULES(CPPUNIT, cppunit > 1.12.0)

How to reproduce the bug?

if this line is uncommented, an error message will appear ./configure: line 14540: syntax error near unexpected token CPPUNIT,' ./configure: line 14540: PKG_CHECK_MODULES(CPPUNIT, cppunit > 1.12.0)'

What behavior did you expect?

No error message

In which environment did the bug occur?

gansm commented 2 years ago

That's odd. Ubuntu 20.04 should provide CppUnit in version 1.15.1-2.

What screen output do you get with these commands? 

pkg-config --print-provides cppunit
dpkg -s $(dpkg -l '*cppunit*' | grep 'libcppunit-[0-9]' | cut -d' ' -f3) | grep '^Version:'
Barchfeld commented 2 years ago

thanks for the quick reply

pkg-config --print-provides cppunit cppunit = 1.15.1

dpkg -s $(dpkg -l 'cppunit' | grep 'libcppunit-[0-9]' | cut -d' ' -f3) | grep '^Version:' Version: 1.15.1-2build1

cat /etc/os-release NAME="Ubuntu" VERSION="20.04.4 LTS (Focal Fossa)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 20.04.4 LTS" VERSION_ID="20.04"

I've made a 'make distclean' followed by 'autoreconf ... etc.' --> no error ...

gansm commented 2 years ago

Sorry to ask again, did you not install anything afterwards (e.g. pkg-config) between your two tests?

Barchfeld commented 2 years ago

Could be. I have installed other packages in the meantime. I did the same for Ubuntu 20.04 on WSL (Windows 10). No errors. Must have been my mistake.

After no more errors were displayed, I ran the following:

make distclean
autoreconf --install --force
./configure --prefix=/usr CXXFLAGS="-g -O0 -DDEBUG -DUNIT_TEST" --with-unit-test
make test
gcc is gcc-12.1.0

gansm commented 2 years ago

This looks like the problem I fixed last week. Since the Linux kernel 5.13.0-1023 the behavior of the ioctl TIOCSTI has changed, so that after an EOT no further characters can be read. Therefore, I had to change input("A"); input("B"); to input("AB"); in my fkeyboard unit test.

The fix: https://github.com/gansm/finalcut/commit/317883a82bc9c7bba9137746b115bfffcf3bba25#diff-0aa01eb3aba1ae0b403c91b3478d00fae585cf400b0bea930a50eba1b87b99c2

I think you are still using a version before May 25, 2022 that did not have this fix in it. Please try again with the latest version.

What happens if you start the unit test separately?

& test/fkeyboard_test

Please do not make any keystrokes while the test is running. Ensure that no background processes are running that can output characters to the terminal.

When the process crashes, a backtrace would be helpful.

If I look at https://github.com/maxmind/libmaxminddb/issues/216 it seems, that something is missing at the function call. But it is for strlen, not strcmp.

Sorry for the incorrect gdb command.

Very strange, in line 3096 there is no call at all.

What do you have in line 3096?

sed -n '3096p' test/fkeyboard-test.cpp

Do you get the same result with these commands?

& make distclean
& ./build.sh unit-test

Maybe you still have an old version of libfinal.so.0 installed?

& ldd test/.libs/fkeyboard_test

Even helpful would be to call these debug commands after the crash.

Okay, we have the following situation:

It looks like the memory behind kstr was not allocated.

We have the following escape sequences:

ESC  O  w

 1b 4f 79 
ESC  O  y

 1b 4f 75

 1b 4f 73
ESC  O  s

Segmentation fault

input("\033Os") is the last call made by sequencesTest(). The next test is mouseTest(). The first entry here is input("\033[M Z2")

What would be helpful now is buf_len and the content of fifo_buf.

The output of infocmp -x may also be relevant.

I think we should focus more on the data source. Could you please include the following debug lines in FKeyboard::getTermcapKey()?

inline FKey FKeyboard::getTermcapKey()
{
  // Looking for termcap key strings in the buffer

  static_assert ( FIFO_BUF_SIZE > 0 , "FIFO buffer too small" );

  if ( key_cap_ptr.use_count() == 0 )
    return NOT_SET;

  const auto buf_len = fifo_buf.getSize();

//------ DEBUG OUTPUT ------
  std::cerr << "buf_len = " << buf_len << "\n";
  std::cerr << "array size = " << key_cap_ptr->size() << "\n";
  std::cerr << "difference1 = " << (key_cap_ptr->cend() - key_cap_ptr->cbegin()) << "\n";
  std::cerr << "difference2 = " << (key_cap_end - key_cap_ptr->cbegin()) << "\n";
  //for (const auto& cap_key : *key_cap_ptr)
  //  std::cerr << "{ '" << (cap_key.string ? "1" : "0") << "', " << cap_key.length << " }\n";
//------ DEBUG OUTPUT ------

  const auto& found_key = std::find_if
  (
    key_cap_ptr->cbegin(),
    key_cap_end,
    [this, &buf_len] (const auto& cap_key)
    ...

Your output should then look like these lines:

FKeyboardTest::mouseTest
^[[M Z2buf_len = 1
array size = 188
difference1 = 188
difference2 = 188
buf_len = 2
array size = 188
difference1 = 188
difference2 = 188
buf_len = 3
array size = 188
difference1 = 188
difference2 = 188
buf_len = 4
array size = 188
difference1 = 188
difference2 = 188
buf_len = 5
array size = 188
difference1 = 188
difference2 = 188

I've changed the lines: grafik

If I uncomment the for - loop:

Great, there we have the problem! The pointer to the end of the std::array points beyond the end.

The question now is - Why do you get a wrong end-iterator from the std::array?

Perhaps the reinterpret_cast confused the compiler on your system. I have now modified my code a bit (5619f6c). Could you run again with these modifications, please?

Barchfeld commented 2 years ago 
git reset --hard
git clean -fd
git pull https://github.com/gansm/finalcut.git

now, with g++-9, it works:

=========================================
   finalcut 0.8.1: test/test-suite.log

# TOTAL: 28
# PASS:  28
# SKIP:  0
# XFAIL: 0
# FAIL:  0
# XPASS: 0
# ERROR: 0

.. contents:: :depth: 2

with g++-12.1 nothing changed. I get the same error again.

gansm commented 2 years ago

I made a few more changes (92c501f) and hope that the unit test with g++ 12.1 runs error-free for you.

Could you test this on your system to verify if this is the case?

alavaelian commented 1 year ago

man this thing is like chinesse for me

gansm commented 1 year ago

@alavaelian is right! I would need some clarity here if the (segmentation fault) crashes with g++-12.1 are still an issue.

@Barchfeld: Could you please test again if the current code fixes this problem? I require your support here. Unfortunately, I can't check it myself because I can't reproduce this error.
