+# 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.
