Description Christian Stadelmann 2017-01-18 15:36:15 UTC
Version-Release number of selected component (if applicable):
eclipse-pydev-5.4.0-1.fc25.x86_64

How reproducible:
on every restart of eclipse which causes pylint to run on all python files of opened projects

Steps to Reproduce:
1. restart eclipse with python projects opened
2. watch system load, processes CPU usage, CPU and IO priority

Actual results:
Eclipse starts a bunch of pylint / python processes, each of them running at normal CPU and IO priority. If there are enough of them, the computer will start lagging.

Expected results:
Run background workers at lower priority, preferably both CPU and IO priority.

Additional info:
Workaround: In Window → Preferences → PyDev → PyLint, reduce "Max simultaneous processes for PyLint" to a number less than your number of cores. Issue might still happen, but most of the time the python processes will run on one core only each.

Comment 1 Fedora End Of Life 2017-11-16 19:44:01 UTC
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '25'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Comment 3 Ben Cotton 2018-11-30 18:26:47 UTC
Fedora 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
