NAMEpython3-abrt − python3-abrt Documentation High−level API for querying, creating and manipulating problems handled by ­ABRT in Python. It works on top of low−level DBus or socket API provided by ABRT. Socket API serves only as a fallback option for systems without new DBus problem API as it can only handle the creation of new problems. This project lives in the ­abrt repository and is distributed under GPLv2 license. Contents:
USAGE EXAMPLES
Creating new problem import problem prob = problem.Runtime( reason='egg_error_message: assertion "error" failed', ) prob.add_current_process_data() prob.add_current_environment() prob.save()
Creating problem for different executable import problem prob = problem.Selinux(reason='Front fell off') prob.executable = '/usr/bin/time' prob.save()
Adding custom data import problem prob = problem.Runtime( reason='Error getting devices:' 'GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: ' 'No such interface `org.gnome.SettingsDaemon.Power` on object at path ' '/org/gnome/SettingsDaemon/Power' ) prob.add_current_process_data() prob.custom_data = 'any' prob['dict_access_example'] = 'works' print(prob) print('') for key, value in prob.items(): print('{0}={1}'.format(key, value)) print('Identifier:', prob.save())
Querying problems import problem for prob in problem.list(): print(prob) print(repr(prob.time)) if hasattr(prob, 'pid'): print(prob.pid)
Querying all problemsThe list method used with auth=True parameter will try to authenticate via ­polkit to gain access to all problems on the system. If there is no authentication agent running or authentication is unsuccessful, the list of problems which belong to current user is returned (same as returned by the list method). import problem for prob in problem.list(auth=True): print(prob) if hasattr(prob, 'username'): print('Problem belongs to {0}'.format(prob.username))
Editing existing problems import problem for prob in problem.list(): if prob.type == problem.JAVA: prob.delete() if prob.type == problem.CCPP: if 'password' in prob.backtrace: del prob.backtrace prob.save() if prob.type == problem.KERNELOOPS: prob.backtrace = prob.backtrace.replace(' ?', '') prob.save()
Watching for new problems import problem import logging logging.basicConfig(level=logging.DEBUG) def monitor(prob): print(prob) prob.delete() pwatch = problem.get_problem_watcher() pwatch.add_callback(monitor) try: pwatch.run() except KeyboardInterrupt: pwatch.quit()
Watching for new problems in a thread from __future__ import print_function import sys import time import problem import threading class ProblemWatchThread(threading.Thread): def __init__(self): super(ProblemWatchThread, self).__init__() self.pwatch = problem.get_problem_watcher() self.pwatch.add_callback(self.handle) self.probcount = 0 def handle(self, prob): self.probcount += 1 print('{0}: {1}'.format(self.probcount, prob)) # prob.delete() def run(self): self.pwatch.run() def stop(self): self.pwatch.quit() pwt = ProblemWatchThread() pwt.start() i = 0 print('Waiting for new problem to appear') spinner = ['\\', '|', '/', '−'] try: while True: time.sleep(0.1) print('{0}\r'.format(spinner[i]), end='') i += 1 i = i % len(spinner) sys.stdout.flush() except KeyboardInterrupt: pwt.stop() pwt.stop()
Getting bug numbers of problems reported to bugzilla import problem bugs = set() for prob in problem.list(): if not hasattr(prob, 'reported_to'): continue for line in prob.reported_to.splitlines(): if line.startswith('Bugzilla:'): bug_num = int(line.split('=')[−1]) bugs.add(bug_num) print(bugs)
STABLE API DOCUMENTATION class problem.Problem(typ, reason, analyzer=None)  Base class for the other problem types. No need to use this class directly, use one of the specific problem classes. add_current_environment()  Add environment of current process to this problem object add_current_process_data()  Add pid, gid and executable of current process to this problem object chown()  Assures ownership of a problem for the caller delete()  Delete this problem prefetch_data()  Prefetch possible data fields of this problem save()  Create this problem or update modified data Create or update the project if some of its fields were modified. Return None in case of modification, identifier if new problem was created. problem.get(identifier, auth=False)  Return problem object matching identifier Return None in case the problem does not exist. Use auth=True if authentication should be attempted. problem.get_problem_watcher(auth=False)  Return ProblemWatcher object which can be used to attach callbacks called when new problem is created Use auth=True if authentication should be attempted for new problem that doesn't belong to current user. If not set such a problem is ignored. problem.list(auth=False)  Return the list of the problems Use auth=True if authentication should be attempted. If authentication via polkit fails, function behaves as if auth=False was specified (only users problems are returned).
Specific problem types class problem.Ccpp(reason)  C, C++ problem class problem.Java(reason)  Java problem class problem.Kerneloops(reason)  Kerneloops problem class problem.Python(reason)  Python problem class problem.Python3(reason)  Python3 problem class problem.Runtime(reason)  Runtime problem class problem.Selinux(reason)  Selinux problem class problem.Unknown(reason)  Unknown problem class problem.Xorg(reason)  Xorg problem
ProblemWatcher class problem.watch.ProblemWatcher(auth)  New problem signal handler attached to DBus signal Use auth=True if authentication should be attempted for new problem that doesn't belong to current user. If not set such a problem is ignored. add_callback(fun)  Add callback to be called when new problem occurs. Each callback function receives Problem instance quit()  Stop event listener loop run()  Start event listener loop
PROBLEM OBJECT PROPERTIESCurrently, there is no strict specification of problem properties and you are free to add your own data as you see fit (log files, process data) provided you are planning to use them for reporting. Mandatory properties required prior saving: Property Meaning Example executable Executable path of the component which caused the problem. Used by the server to determine component and package data. '/usr/bin/time' Following properties are added by the server when new problem is created: Property Meaning Example component Component which caused this problem. 'time' hostname Hostname of the affected machine. 'fiasco' os_release Operating system release string. 'Fedora release 17 (Beefy Miracle)' uid User ID 1000 username 'jeff' architecture Machine architecture string 'x86_64' kernel Kernel version string '3.6.6−1.fc17.x86_64' package Package string 'time−1.7−40.fc17.x86_64' time Time of the occurrence (unixtime) datetime.datetime(2012, 12, 2, 16, 18, 41) count Number of times this problem occurred 1 Parsed package data is also available: Property Meaning Example pkg_name Package name 'time' pkg_epoch Package epoch 0 pkg_version Package version '1.7' pkg_release Package release '40.fc17' pkg_arch Package architecture 'x86_64' Other common properties (presence differs based on problem type): Property Meaning Example Applicable abrt_version ABRT version string '2.0.18.84.g211c' Crashes caught by ABRT cgroup cgroup (control group) information for crashed process '9:perf_event:/\n8:blkio:/\n...' C/C++ core_backtrace Machine readable backtrace with no private data C/C++, Python, Ruby, Kerneloops backtrace Original backtrace or backtrace produced by retracing process C/C++ (after retracing), Python, Ruby, Xorg, Kerneloops dso_list List of dynamic libraries loaded at the time of crash C/C++, Python maps Copy of /proc/<pid>/maps file of the problem executable C/C++ cmdline Copy of /proc/<pid>/cmdline file '/usr/bin/gtk−builder−convert' C/C++, Python, Ruby, Kerneloops coredump Coredump of the crashing process C/C++ environ Runtime environment of the process C/C++, Python open_fds List of file descriptors open at the time of crash C/C++ pid Process ID '42' C/C++, Python, Ruby proc_pid_status Copy of /proc/<pid>/status file C/C++ limits Copy of /proc/<pid>/limits file C/C++ var_log_messages Part of the /var/log/messages file which contains crash information C/C++ suspend_stats Copy of /sys/kernel/debug/suspend_stats Kerneloops reported_to If the problem was already reported, this item contains URLs of the services where it was reported Reported problems event_log ABRT event log Reported problems dmesg Copy of dmesg Kerneloops • ­Index • ­Module Index • ­Search Page
