<div>The main thread creates a coverage instance and

<div>During the lifetime of the program I have

I haven't heard this need before, to occasionally
reset or clear the coverage data from one of many
threads. Can you say more about what the bigger
picture is here? There might be an easier way to get
it done.<br>

Subject: Re: [TIP] are the absolute paths in .coverage
necessary?<br>
Hi Ned,<br>
<br>
Sorry, I meant: do the paths recorded in the .coverage
files need to be absolute or could Coverage be changed
to just record the path relatively to the current
working directory at the start of execution?<br>
<br>
cheers,<br>

Chris, as far as I can tell, they do not have to be
absolute. As you can<br>
see from the sample of my rc file, you can replace an
arbitrary prefix<br>
with *, and it will work just fine. How about this:<br>
<br>
[paths]<br>
mylib =<br>
mylib<br>
*/workspace/PYTHON/*/mylib<br>
tests =<br>
tests<br>
*/workspace/PYTHON/*/tests<br>

What I currently have is:<br>

mylib =<br>

/data/jenkins/jobs/mylib-<wbr>test/workspace/PYTHON/*/mylib<br>
tests =<br>
tests<br>
/data/jenkins/jobs/mylib-<wbr>test/workspace/PYTHON/*/tests<br>

How can I remove the absolute bits of that?<br>
<br>
But, back to my original question: why are the paths
in .coverage<br>
absolute in the first place? :-)<br>

Chris, can you show the absolute paths you are
using? I have this in my<br>
rc file to deal with varieties of CI:<br>
<br>
[paths]<br>
source =<br>

Hi Ned,<br>
<br>
Are the absolute paths necessary in .coverage?<br>
<br>
The reason I ask is that if, for example, they
were relative to the<br>
cwd, then I wouldn't need a .coveragerc with a
whole bunch of paths<br>
predicated on the exact filesystem layout of my
CI server.<br>
<br>
thoughts?<br>
