libjob 0.1.0

Python warpper of the Windows job feature, replacement of the resource library

LibJob

LibJob is the python wrapper of windows's job feature, which could replace resource easily.

Using Example & Compares(when applying 100MB memory limit to given two processes): by resource standard library:

curlimit = resource.prlimit(pid1, resource.RLIMIT_VMEM)
resource.prlimit(pid1, resource.RLIMIT_MEMLOCK, (100 * 1024 * 1024, curlimit[1]))
curlimit = resource.prlimit(pid2, resource.RLIMIT_VMEM)
resource.prlimit(pid2, resource.RLIMIT_MEMLOCK, (100 * 1024 * 1024, curlimit[1]))

by using pywin32

job = win32job.CreateJobObject(None, "")
extended_info = win32job.QueryInformationJobObject(job, win32job.JobObjectExtendedLimitInformation)
extended_info["ProcessMemoryLimit"] = 100 * 1024 * 1024
extended_info["BasicLimitInformation"]["LimitFlags"] |= win32job.JOB_OBJECT_LIMIT_PROCESS_MEMORY
win32job.SetInformationJobObject(job, win32job.JobObjectExtendedLimitInformation, extended_info)
proc = win32api.OpenProcess(win32con.PROCESS_SET_QUOTA | win32con.PROCESS_TERMINATE, False, pid1)
win32job.AssignProcessToJobObject(job, proc)
proc = win32api.OpenProcess(win32con.PROCESS_SET_QUOTA | win32con.PROCESS_TERMINATE, False, pid2)
win32job.AssignProcessToJobObject(job, proc)

by using libjob

job = libjob.Job()
job.process_memory_limit = 100 * 1024 * 1024
job.assign(pid1)
job.assign(pid2)
