Test code coverage

[Victor Kirkebo]

This patch adds test coverage to the 'make test' target.
gcov is used for gcc and tcov is used for Sun studio compiler.

Hey,

Think this could be modified to not spit coverage on files not in the
source tree?

File '/usr/include/gentoo-multilib/amd64/sys/stat.h'
Lines executed:0.00% of 1
/usr/include/gentoo-multilib/amd64/sys/stat.h:creating 'stat.h.gcov'

File '/usr/include/gentoo-multilib/amd64/stdlib.h'
Lines executed:27.27% of 11
/usr/include/gentoo-multilib/amd64/stdlib.h:creating 'stdlib.h.gcov'

File 'slabs.c'
Lines executed:16.39% of 122
slabs.c:creating 'slabs.c.gcov'

File '/usr/include/gentoo-multilib/amd64/stdlib.h'
Lines executed:0.00% of 3
/usr/include/gentoo-multilib/amd64/stdlib.h:creating 'stdlib.h.gcov'

Anyone else have comments?

Hi,
I've attached a new version of this patch that excludes printing of
coverage on non-source-tree files.
The printout looks like this:

with gcov:
File `assoc.c' Lines executed:1.66% of 181
File `items.c' Lines executed:2.82% of 248
File `memcached.c' Lines executed:9.40% of 1554
File `slabs.c' Lines executed:14.84% of 128
File `stats.c' Lines executed:2.60% of 77

with tcov:
assoc.c : 1.02 Percent of the file executed
items.c : 2.39 Percent of the file executed
memcached.c : 8.15 Percent of the file executed
slabs.c : 15.65 Percent of the file executed
stats.c : 1.72 Percent of the file executed

The test coverage is exceptionally low.

Is this only accounting the coverage of the last executed test?

[Victor Kirkebo]

You're right - something is very wrong with the numbers.
It only seems to report coverage for the tests in 00-startup.t. If I try
to run only the tests in any of the other *.t files there's no output.
I'm not sure why this happens but will look into it.

Memcached::Handle::DESTROY needs to kill the memcached process with
SIGINT (instead of SIGKILL).
Now the numbers look better:
File 'assoc.c' Lines executed:49.13% of 173
File 'items.c' Lines executed:70.61% of 228
File 'memcached.c' Lines executed:65.32% of 1485
File 'slabs.c' Lines executed:84.43% of 122
File 'stats.c' Lines executed:90.00% of 70
