Bug#682024: apt-get: custom --solver stub crashes apt-get in glibc
Package: apt
Version: 0.9.7.1
Severity: minor
File: /usr/bin/apt-get
Dear Maintainer,
I created an external apt-cudf solver specification as per apt-cudf instructions.
My "solver" (as of yet, a stub) is:
-- minimal_progressive.py solver --
#!/usr/bin/env python
import sys
def main():
if len(sys.argv) != 4:
return 1
cudf_in = open(sys.argv[1])
cudf_out = open(sys.argv[2], 'w')
cudf_in.read() # read the whole piped input
cudf_out.write('Error:') # write something irrelevant
return 1 # return with error
if __name__ == '__main__':
sys.exit(main())
-- end minimal_progressive.py --
I run apt-get and get the following output (reproducible):
-- start output --
user@debian:~$ sudo apt-get -s upgrade --solver minimal_progressive

Despite my not following the CUDF protocol (haven't come that far yet), I don't think apt-get should exactly crash in glibc.
