# A report generator for gcov 3.4
#
# This routine generates a format that is similar to the format generated
# by the Python coverage.py module. This code is similar to the
# data processing performed by lcov's geninfo command. However, we
# don't worry about parsing the *.gcna files, and backwards compatibility for
# older versions of gcov is not supported.
#
# Outstanding issues
# - verify that gcov 3.4 or newer is being used
# - verify support for symbolic links
#
# gcovr is a FAST project. For documentation, bug reporting, and
# updates, see https://software.sandia.gov/trac/fast/wiki/gcovr

# This is UGLY. Here's why: UNIX resolves symbolic links by walking the
# entire directory structure. What that means is that relative links
# are always relative to the actual directory inode, and not the
# "virtual" path that the user might have traversed (over symlinks) on
# the way to that directory. Here's the canonical example:
#
# a / b / c / testfile
# a / d / e --> ../../a/b
# m / n --> /a
# x / y / z --> /m/n/d
#
# If we start in "y", we will see the following directory structure:
# y
# |-- z
# |-- e
# |-- c
# |-- testfile
#
# The problem is that using a simple traversal based on the Python
# documentation:
#
# (os.path.join(os.path.dirname(path), os.readlink(result)))
#
# will not work: we will see a link to /m/n/d from /x/y, but completely
# miss the fact that n is itself a link. If we then naively attempt to
# apply the "c" relative link, we get an intermediate path that looks
# like "/m/n/d/e/../../a/b", which would get normalized to "/m/n/a/b"; a
# nonexistant path. The solution is that we need to walk the original
# path, along with the full path of all links 1 directory at a time and
# check for embedded symlinks.
#
#
# NB: Users have complained that this code causes a performance issue.
# I have replaced this logic with os.walk(), which works for Python >= 2.6

# Process a datafile (generated by running the instrumented application)

#
# This is trickier than it sounds: The gcda/gcno files are stored in the
# same directory as the object files; however, gcov must be run from the
# same directory where gcc/g++ was run. Normally, the user would know
# where gcc/g++ was invoked from and could tell gcov the path to the
# object (and gcda) files with the --object-directory command.
# Unfortunately, we do everything backwards: gcovr looks for the gcda
# files and then has to infer the original gcc working directory.
#
# In general, (but not always) we can assume that the gcda file is in a
# subdirectory of the original gcc working directory, so we will first
# try ".", and on error, move up the directory tree looking for the
# correct working directory (letting gcov's own error codes dictate when
# we hit the right directory). This covers 90+% of the "normal" cases.
# The exception to this is if gcc was invoked with "-o ../[...]" (i.e.,
# the object directory was a peer (not a parent/child) of the cwd. In
# this case, things are really tough. We accept an argument
# (--object-directory) that SHOULD BE THE SAME as the one povided to
# gcc. We will then walk that path (backwards) in the hopes of
# identifying the original gcc working directory (there is a bit of
# trial-and-error here)
