the actual application. The bug was caused by a timestamp issue.
* Issue #18: Provide explanation and possible workaround for SIGILL problems
with GCC 4.1.2
* Issue #23: Warn if a binary has no debug symbols

* HTML: Always put merged results last and don't include them in sorting
* HTML: Coloring improvements (?) of the HTML output
* HTML: Refactor HTML output completely to use javascript-based pages.
This allows selecting how to sort directly from the web page,
and greatly simplifies the generating C++ code
* Correct filtering bug in the merged output, where the last
run would filter out data from the previous runs
* Issue #20: Fix hanging-on-killed-by-signal
-- Simon Kagstrom <simon.kagstrom@gmail.com>, Mon Jun 9 19:12:38 CEST 2014
Kcov (17):

-- Simon Kagstrom <simon.kagstrom@gmail.com>, Sun May 18 19:24:14 CEST 2014
Kcov (16):
* kernel-engine: Implement an engine to handle kernel code coverage
collection (not finished)
* kprobe-coverage: Refactor the kernel module so that it basically
works now
* Code refactoring and more C++11-izing
* Python: Filter out some false negatives (i.e., non-executable
lines marked as red)
* Python: Report absolute paths so that output filtering works
* Python: Catch exceptions in the python helper to avoid EOF etc
being propagated upwards (and coverage collection to fail)
* Python: Fix a case where the engine would simply hang on waiting
for more data
-- Simon Kagstrom <simon.kagstrom@gmail.com>, Fri Mar 21 16:38:28 CET 2014
Kcov (15):
* Workaround a shared-library issue where kcov would sometimes hang on
the malloc. 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, 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 <simon.kagstrom@gmail.com>, Tue Dec 7 18:20:28 CET 2010
Kcov (3):
* Various bug fixes
* Add ability to trace running processes by PID

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 <simon.kagstrom@gmail.com>, Sun Oct 24 09:15:39 CEST 2010
Kcov (1):
* Initial release
