<div style="margin: 8px 0; padding: 0 12px; color: #74777D;"><p style="padding: 0; margin: 8px;">What should we do for Windows? Do we support any other platforms that doesn't have lsof?</p></div></div>
<div style="margin: 8px 0; padding: 0 12px;"><p style="padding: 0; margin: 8px;">This reminds me of KCoreAddons' new KProcessInfo class, although that one doesn't actually do this.</p>
<p style="padding: 0; margin: 8px;">I see that FreeBSD and OSX have lsof (and the man page doesn't say those options are missing there) so it should be fine, everywhere except Windows.</p>
<p style="padding: 0; margin: 8px;">In general I don't really like starting executables like this, but indeed writing a clone of lsof sounds like much work.</p></div></div><br /><div style="border: 1px solid #C7CCD9; border-radius: 3px;"><div style="padding: 0; background: #F7F7F7; border-color: #e3e4e8; border-style: solid; border-width: 0 0 1px 0; margin: 0;"><div style="color: #74777d; background: #eff2f4; padding: 6px 8px; overflow: hidden;"><a style="float: right; text-decoration: none;" href="https://phabricator.kde.org/D21760#inline-122506">View Inline</a><span style="color: #4b4d51; font-weight: bold;">hallas</span> wrote in <span style="color: #4b4d51; font-weight: bold;">klistopenfiles.h:40</span></div>
<div style="margin: 8px 0; padding: 0 12px; color: #74777D;"><p style="padding: 0; margin: 8px;">I am very much in doubt about what a nice interface for this should be? I was thinking of an alternative approach where you would instantiate a class, connect to a signal on the class and then invoke a method to start the listing process, you would then receive the result on a slot instead. What do you guys think?</p></div></div>
<div style="margin: 8px 0; padding: 0 12px;"><p style="padding: 0; margin: 8px;">Reading the unittest, I definitely agree that a signal would be better. Then you could use QSignalSpy::wait() without the need to use QEventLoop by hand :-)</p>
<p style="padding: 0; margin: 8px;">This is really a job. I would inherit KJob for this, actually. It's the way we do such things everywhere else.</p></div></div></div></div></div><br /><div><strong>REPOSITORY</strong><div><div>R244 KCoreAddons</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D21760">https://phabricator.kde.org/D21760</a></div></div><br /><div><strong>To: </strong>hallas, davidedmundson, broulik, Frameworks, dfaure, bruns, Plasma<br /><strong>Cc: </strong>kde-frameworks-devel, LeGast00n, sbergeron, michaelh, ngraham, bruns<br /></div>
