Description RJVB 2018-11-30 11:13:23 UTC

Application: kdevelop (5.3.0-37-ge1a51bd359)
 (Compiled from sources)
Qt Version: 5.9.7
Frameworks Version: 5.52.0
Operating System: Linux 4.14.23-ck1-mainline-core2-rjvb x86_64
Distribution: Ubuntu 14.04.5 LTS

-- Information about the crash:
- What I was doing when the application crashed:

1 Open a project for the KDevelop source tree in KDevelop
2 apply a patch and trigger the patch review plugin
3 select "export diff"/Phabricator

crash.

Possibly related to this terminal warning:
DiffListModel::refresh() called while still active!

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault

New crash information added by DrKonqi

sharetool (1.0) using Qt 5.9.7

Confirmation of the crash using the `sharetool` test utility from the Purpose sources.

`testphabricator --list` still returns the correct list so this doesn't appear related to an unexpected change in phabricator's output.

Comment 2 RJVB 2018-11-30 15:04:26 UTC

The crash goes away when I change the std::sort() call back to `qSort()`, so commit #b40009c31642e43ed34109778b8aea1e7b8b1520 introduced a regression.

Laurent, what was the reason for replacing qSort()?

Comment 3 RJVB 2018-11-30 21:29:04 UTC

Git commit 36b17c15e01bccfc4b796486ae1729ac02863dff by René J.V. Bertin.
Committed on 30/11/2018 at 21:27.
Pushed by rjvbb into branch 'master'.

phabricator plugin: use Arcanist's diff.rev. order

No longer attempt to sort reviews (by title) but instead use the order
in which Arcanist returns the open diff. revisions (chronologically,
threaded by status).
The alphabetical sorting never worked to satisfaction and the recent
change to using std::sort() caused a crash with and in Qt 5.9.7 on Linux.
