How to find the code changes that fixed a particular Bug?

rajeshbk

Hi,

We are currently using QT 4.7 for an application and using ListView. We are currently experiencing memory leak and found this is fixed as part of Bug "QTBUG-25784 : QML Listview has memory leaks when QList<QObject*> model is used".

The fix is available in release 4.8.2 but I do not want to upgrader my QT version now. How can I find the actual code fix for the bug so that I can source the same in version 4.7. Please let me know the steps to find the same.

Thanks & Regards,
Rajesh B.K

You need to look at "All" activity on this Jira item. There is the link to gerrit change-id: "link":https://codereview.qt-project.org/#change,26452.

Thanks a lot, It helped a lot.

sierdzio

Pleasure.

The interface could be more user-friendly, to be honest :/

SGaist

Agreed, this might be a feature request ? :)

sierdzio

Probably, yes. Jira is rather flexible, it should facilitate such a change.

One more query, How do we map the Bug ID say QTBUG-25784 to the Review ID in Jira. I tried seaching in Jira by bug ID, but no search result found.

sierdzio

That is probably not really possible :( Maybe with some advanced search, I don't really know.

Okay, Then how did you find the right entry for the QTBUG-25784 in Jira? Scrolled accross all the Jira entries ?

sierdzio

Go to "Source" "tab":https://bugreports.qt-project.org/browse/QTBUG-25784?page=com.atlassian.jirafisheyeplugin:fisheye-issuepanel - there is a Change-ID entry there. Copy the id and search for it on gerrit.

Sorry if I am appearing too dumb :)

In bugreports.qt-project.org for the given bug I could not find the change ID. I understand from your link https://codereview.qt-project.org/#change,26452 that the change ID is 26452.

But I could neither find the source tab nor the ID 26452 in the Jira

Could you please let me know if I am missing something?

sierdzio

No. This is change-ID for given item: I1d6cd4dfc2530424535a7e00164563d9b4aaa513.

Okay, But I am unable to find this change ID in https://bugreports.qt-project.org/browse/QTBUG-25784

Neither do I find the source tab. Is Login to https://bugreports.qt-project.org/ required to view the change ID ?

sierdzio

Ha, bingo :) I didn't know about that, but yes, you need to be logged in. When I logged out, I could not see the change ID anymore.

This is bad. We're talking about GUI toolkit and our bug reporting tool has inconvenient UI... a bit ironic, isn't it? xD

SGaist

Indeed... Another feature request ? :)

sierdzio

Done: "link":https://bugreports.qt-project.org/browse/QTJIRA-227. Please watch and vote ;)

Thanks. I could get the change ID for that Bug, But for another bug QTBUG-21747 the source is empty. Is there another path to find the associated code changes?
