I found where it comes from - in order to compile a function its signature needs to be 0-indented. Therefore if original function definition is n-indented then PP removes leading n spaces from every line. It works for code (which must be indented to the right from where signature starts) but does not handle unindented comments well.
I'll fix it in the next release.
If a function is not indented then it would work as expected:
#!/usr/bin/env /usr/bin/python
"""Demonstrate bug in pp"""
import pp
def fitnessFunction():
# print "This prints, despite the fact that IT IS COMMENTED OUT!"
return 0
def main():
parallel = 1 # bug happens only when using pp
if parallel:
job_server = pp.Server()
jobs = []
for i in xrange(3):
if parallel:
jobs.append(job_server.submit(fitnessFunction, ()))
else:
jobs.append(lambda: fitnessFunction())
for task in jobs:
fitness = task()
main()
As it was already shown above it would also work for if comments are indented:
#!/usr/bin/env /usr/bin/python
"""Demonstrate bug in pp"""
import pp
def main():
parallel = 1 # bug happens only when using pp
def fitnessFunction():
# print "This prints, despite the fact that IT IS COMMENTED OUT!"
return 0
if parallel:
job_server = pp.Server()
jobs = []
for i in xrange(3):
if parallel:
jobs.append(job_server.submit(fitnessFunction, ()))
else:
jobs.append(lambda: fitnessFunction())
for task in jobs:
fitness = task()
main()
