<div style="margin: 8px 0; padding: 0 12px; color: #74777D;"><p style="padding: 0; margin: 8px;">I tried various ways to call this as a subjob, but all of them leads to breakage of non xattr related tests. Maybe some major changes to the class are needed.</p>
<p style="padding: 0; margin: 8px;">But the call can be asynchronous with little effort. All tests still pass if <tt style="background: #ebebeb; font-size: 13px;">start()</tt> is called, instead of <tt style="background: #ebebeb; font-size: 13px;">exec()</tt>.</p></div></div>
<div style="margin: 8px 0; padding: 0 12px;"><p style="padding: 0; margin: 8px;">That sounds racy; the subjob might not be finished by the time the main job is finished, if you just "start and forget".</p>
<p style="padding: 0; margin: 8px;">I cannot accept this commit with an exec() in here. The easy and modern way to make this async is just a connect and a lambda (which contains the rest of the code here).</p>
<p style="padding: 0; margin: 8px;">I have to wonder though: do we have a fast way to determine whether we actually need the additional subjob? (to avoid making this slower on systems -- or files -- without xattr)</p>
<p style="padding: 0; margin: 8px;">Hmm, or a much bigger architectural question: why doesn't kio_file copy the xattr as part of FileProtocol::copy(), as it already does with e.g. permissions and ACLs, instead of doing this in a separate job?</p></div></div></div></div></div><br /><div><strong>REPOSITORY</strong><div><div>R241 KIO</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D17816">https://phabricator.kde.org/D17816</a></div></div><br /><div><strong>To: </strong>tmarshall, dfaure, chinmoyr, bruns, Frameworks, cochise<br /><strong>Cc: </strong>tmarshall, arrowd, cfeck, bruns, phidrho, dhaumann, funkybomber, abika, pino, davidedmundson, ngraham, atha.kane, spoorun, nicolasfella, kde-frameworks-devel, LeGast00n, GB_2, michaelh<br /></div>
