Description Marek Suchánek 2018-04-07 12:09:43 UTC
Description of problem: In the Activities search field, if I type an expression that can be evaluated by the Calculator search plugin, the calculation keeps running even after I close Activities. This becomes a problem when the expression is extremely hard to calculate but easy to type: a good example is "10!!!". This causes the gnome-calculator process to keep running in the background and consuming 100% CPU. Version-Release number of selected component (if applicable): Fedora 27 with Gnome 3.26.2. How reproducible: Always. Steps to reproduce: 1. Enable the Calculator search plugin. 2. Open Activities. 3. Type "10!!!" in the search field. Calculator now attempts to calculate a ridiculously big factorial. 4. Close activities. Actual results: The gnome-calculator process is using 100% of a single core, because the factorial would take ages to compute. Your laptop fan is suddenly whirring for no apparent reason. Expected results: The Calculator operation is terminated as soon as the Activities search is closed. There is no surprising CPU usage. Possibly, the search could also sanitize Calculator input to prevent too demanding calculations, but this seems like a much more complex solution. Additional info: This could potentially be a Calculator bug, too. Feel free to reassign it as necessary. I've also filed an issue on the new Gnome GitLab, because I wasn't sure which place is better for this: https://gitlab.gnome.org/GNOME/gnome-shell/issues/183

I've also tested this on RHEL 7.4 in a VM. The result is the same.

This message is a reminder that Fedora 27 is nearing its end of life. On 2018-Nov-30 Fedora will stop maintaining and issuing updates for Fedora 27. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '27'. 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 27 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.

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.
