The workaround uses a static memory buffer instead. * Implemented support for collecting Python code coverage! Usage is the same as for compiled code. * Code-restructuring to allow multiple "engines", which makes it possible to add the python support above. * More C++11-izing of the code -- Simon Kagstrom , Sun Mar 2 10:50:00 CET 2014 Kcov (14): * Add two options, --collect-only and --report-only to only collect coverage and produce Cobertura/HTML output respectively. Can be used for example on embedded systems where the source code isn't available. * PowerPC support has been added (thanks to Aleksandr Vilchinskii and Konstantin Polivtsev for testing this) -- Simon Kagstrom , Wed Feb 5 19:42:03 CET 2014 Kcov (13): * Don't hang the kcov main process if a breakpoint comes in before the solib handler constructor has executed (depends on the construction order) * Correct bug with realloc in solib handling (malloc all data once only) -- Simon Kagstrom , Sun Dec 8 19:34:37 CET 2013 Kcov (12): * Fix lockup bug in the solib code path (where processes with many solibs would hang at startup) * Correct a crash in the reporter * Add test case for signals * Report from main thread to avoid threading issues * Fairly major refactoring of ptrace code to avoid an issue where two PTRACE_CONTINUE calls could be done without waitpid() in between. This would cause crashes in the traced program. * Add support for looking for debug info in separate files via build-id (Alexander Larsson) * Add --exit-first-process option to fork kcov when covering daemons (otherwise kcov will wait for all children to finish) * Add --skip-solibs option to disable processing of shared libraries, which also works around a bug which sometimes triggers * Add --replace-source-path option for cases where the sources have been moved (James Warner) * Fix linking (Igor Murzov) * Some build fixes to make it build with clang++ * Fix various warnings * Add experimental profiler based on kcov * Add sorting by reverse-percent (high -> low, -u option) * Cache non-existing files to avoid doing lstat calls all the time (slight performance improvement) * closedir() was not called from the html-writer, which creates a resource leak (Karl Vogel) -- Simon Kagstrom , Sat Oct 19 11:06:42 CEST 2013 Kcov (11): * Fix handling of common paths in HTML writer * Fix bug in shared library handling where repeated exec()s would cause strange hangs. Fixed by unsetting the KCOV_SOLIB_PATH environment variable after the first executable has been started. Add test-popen test case to check for this. * Expand ~'s in the --include-path and --exclude-path options * Unbreak accumulating data from multiple runs again (introduced sometime during refactoring), and add test case for this -- Simon Kagstrom , Sat Aug 18 08:45:03 CEST 2012 Kcov (10): * Fix bug where multiple files with the same name would only be shown once in the HTML output. * Fix icache conflict bug (present while instrumenting shared libraries) on multi-CPU systems by forcing all traced processes to one CPU * Re-enable the --pid=PID argument to trace a running process again * Fix race condition in the reporter * Only set breakpoints in executable sections. This avoids problems where the DWARF line information points to non-code sections (which can happen) * Fix coverage reporting of orphaned children (where the parent does not wait(2) for the child * Use std::unordered_map for breakpoints (improves performance somewhat) * Improve unit tests * Add robot-framework testsuite that can be run from a Jenkins server -- Simon Kagstrom , Mon Jul 23 13:28:43 CEST 2012 Kcov (9): * Completely refactor the source code (yes, everything!), and add unit tests to verify kcov itself. The code is now in C++. * Implement transparent coverage instrumentation for shared libraries (done automatically) * Implement a Cobertura-compatible XML backend. This allows integrating kcov coverage information in Jenkins. * Improve performance a lot by filtering out files already at the instrumentation step (and not only during HTML generation). This means that --include-pattern/--include-path can improve kcov performance by quite a bit. -- Simon Kagstrom , Fri Jun 15 17:39:17 CEST 2012 Kcov (8): * Import the man-page from Debian and update it. * Simplify parts of the ptrace code * Correct the sorting of files-by-percentage when the difference is less than 0.5% (thanks Martin!). * Correct the percentage-bar color according to the configured limits in the report. -- Simon Kagstrom , Sun Dec 4 14:13:47 CET 2011 Kcov (7): * Weed out common parts of source paths from the report, display the full path as the HTML title= tag * Fix crash bug in argument passing * Handle hit count a bit better -- Simon Kagstrom , 2011-07-10 Kcov (6): * Correct hit count. The hit count is no longer over the number of possible hits * Better error reporting when stripped or otherwise broken binaries are passed to kcov * Handle files with relative directory paths (lookup the absolute path via DWARF source files). Otherwise, some files are not reported in the output. * Add test program to detect regressions * Detect stripped binaries and report that you'll need to build with -g * Correct --include/exclude-path behavior. The previous version will match PATH*/* instead of just PATH/* (Igor Murzov) * Various small fixes -- Simon Kagstrom , Sat Apr 16 08:28:27 CEST 2011 Kcov (5): * Switch from libdwarf to libdw (from elfutils) for building kcov. libdw is a bit more logical than libdwarf. * Implement actual path matching (Igor Murzov) * Rename path-matching to pattern matching (which is what it does) and set it up using long options. * Parse options with getopt * Don't escape all multibyte characters in the report. That will break display of UTF-8 etc (Igor Murzov) * Improve cmake packaging support (Igor Murzov) -- Simon Kagstrom , Sat Feb 12 15:25:57 CET 2011 Kcov (4): * Build system is now based on cmake (Igor Murzov) * Add MIPS32, ARM and PowerPC architecture support. This is untested though and might very well not work at all. * Add -t option to set the title of the program to test (otherwise it will be the filename) * Refactored the architecture support to allow running i386 programs on x86_64 machines, and easier add other architectures * Make it possible to collect coverage from multiple programs in a single directory, useful for example when running a test suite * Add coverage color to the header as well * Misc refactoring -- Simon Kagstrom , Tue Dec 7 18:20:28 CET 2010 Kcov (3): * Various bug fixes * Add ability to trace running processes by PID * Fix copyright headers -- Simon Kagstrom , Sat Nov 13 08:13:03 CET 2010 Kcov (2): * Misc fixes * Add ability to specify low/high limits * Add state saving between runs. Re-starting the same program will then add to existing coverage instead of starting from scratch. * Link to web page in the report * Add option to sort by percentage or file name -- Simon Kagstrom , Sun Oct 24 09:15:39 CEST 2010 Kcov (1): * Initial release -- Simon Kagstrom
