* Trying again to land OOM priority manager changes.gspencer@google.com2011-08-231-9/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | First landing failed because of an obscure problem with building linux_shared. This change passes the linux_shared trybot (and linux and linux_chromeos trybots). Changing OOM range to 0, 1000 and tweaking OOM algorithm. With this change, we now use the newer oom_score_adj file (with fallback to oom_adj when on a system that doesn't support it) so that we can take advantage of a finer range ([0, 1000] instead of [0, 15]). Also tweaked the OOM priority manager to prioritize things in a slightly different order, preferring (even more) not to kill tabs that the user has currently selected.

* Clean up orphaned testserver processes before launching a new one in ↵rsimha@chromium.org2010-10-051-7/+39
| | | | | | | | | | | | | | | net::TestServer Several chrome tests have failed in recent days because some test cases crashed due to failures, leaving behind orphaned testserver processes. These test suites do not use out_of_proc_test_runner, and therefore, do not get the benefit of using the LaunchAppInNewProcessGroup()/KillProcessGroup() mechanism. This patch implements an added layer of safety, by causing TestServer::LaunchPython() to first kill any remaining orphaned instances of testserver.py before launching a new one. The check for an orphaned testserver process on POSIX is a process with exe_name "python", a parent_pid of "1" (indicating that it's an orphan), and command line parameters that contain the strings "testserver.py" and "<port>" where <port> is the port that is being used by the test server instance.

* Linux: remove the concept of physical memory from the task manager.agl@chromium.org2009-10-071-6/+4
| | | | | | | | | | | | | | | Physical memory isn't a concept on Linux. We have private pages and proportional set size. This patch matches the task manager up with about:memory. 'Private memory' gets you the number of private pages and 'Shared memory' is the PSS (except on systems with old kernels that don't have PSS, where it'll be zero). http://codereview.chromium.org/242096 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@28337 0039d316-1c4b-4281-b951-d872f2087c98
