------------------------------------------
Summary: ProcessTreeKiller doesn't work for cygwin sub-processes
Key: JENKINS-13615
URL: https://issues.jenkins-ci.org/browse/JENKINS-13615
Project: Jenkins
Issue Type: Bug
Components: core
Reporter: Christian Höltje
The ProcessTreeKiller[1] doesn't work for cygwin processes launched from a
cygwin process.
To reproduce:
* Launch a CMD in a terminal.
* set AAA=123
* bash.exe
* sleep 10000
* Look sleep up in Process Explorer and notice that it has only 4 environment
variables, none of which is AAA.
This is because cygwin maintains the environment variables in the shared memory
space for cygwin.dll: See the bottom of
http://cygwin.com/cygwin-ug-net/setup-env.html
One possible solution might be to have a checkbox that enables a cygwin hack
that fires up bash.exe and scans /proc/*/cwd looking for processes that are in
the workspace. Then grabs the /proc/*/winpid and kills them.
The downside is this may kill too much (a random user cd'd into the workspace,
unlikely a problem since it'll prevent directory deletion anyway) and may miss
any processes that cd outside the workspace. But better than nothing.
Ciao!
