[TIP] Using coverage from API and command line gives different results

[Alexander Todorov]

Hello folks,
I'm fairly new to coverage but I've noticed something strange. With the sample 
Python scripts (attached) which include modules I see the following:

If starting coverage from its API the report says:

# ./myprog
Hello __main__
Hello mymodule1
Hello mymodule2

# coverage report
Name        Stmts   Miss  Cover
-------------------------------
mymodule1       2      0   100%
mymodule2       2      0   100%
-------------------------------
TOTAL           4      0   100%


If starting coverage from the command line:

# coverage run ./myprog2
Hello __main__
Hello mymodule1
Hello mymodule2

# coverage report
Name        Stmts   Miss  Cover
-------------------------------
mymodule1       2      0   100%
mymodule2       2      0   100%
myprog2         5      0   100%
-------------------------------
TOTAL           9      0   100%



The difference as seen is that the main program file is not reported. On a 
larger project I'm trying to integrate coverage with I see exactly the opposite 
- the main program file is included in the report while the modules it includes 
are not (not all of them). All modules are in site-packages.


This is with coverage-3.7 on Fedora 20.


Any ideas or comments ? Is this a known issue or a bug?


Regards,
Alex
