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:
<br>
<br>
If starting coverage from its API the report says:
<br>
<br>
# ./myprog
<br>
Hello __main__
<br>
Hello mymodule1
<br>
Hello mymodule2
<br>
<br>
# coverage report
<br>
Name Stmts Miss Cover
<br>
-------------------------------
<br>
mymodule1 2 0 100%
<br>
mymodule2 2 0 100%
<br>
-------------------------------
<br>
TOTAL 4 0 100%
<br>
<br>
<br>
If starting coverage from the command line:
<br>
<br>
# coverage run ./myprog2
<br>
Hello __main__
<br>
Hello mymodule1
<br>
Hello mymodule2
<br>
<br>
# coverage report
<br>
Name Stmts Miss Cover
<br>
-------------------------------
<br>
mymodule1 2 0 100%
<br>
mymodule2 2 0 100%
<br>
myprog2 5 0 100%
<br>
-------------------------------
<br>
TOTAL 9 0 100%
<br>
<br>
<br>
<br>
The difference as seen is that the main program file is not
reported. </blockquote>
Because of the way coverage measurement works in CPython, it can
only start measuring coverage at a function call. Your myprog.py
calls coverage.start(), which makes coverage measurement start at
the next function call, which is into another module. None of the
code in myprog.py is measured because none of it happens within a
function called between .start() and .end().<br>

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 sound like a separate problem, perhaps your modules are
imported before coverage starts?<br>

This is with coverage-3.7 on Fedora 20.

<br>
Any ideas or comments ? Is this a known issue or a bug?
