--- Comment #5 from Andrew Gunnerson <accounts+...@chiller3.com> --- I submitted an MR for skipping directory counts when KFileItem::isSlow() here: https://invent.kde.org/system/dolphin/-/merge_requests/507 --- Regarding the slow stat() calls blocking the UI, I did some further investigation. The stat() calls are coming from KIO::WorkerThread threads, not the UI thread. The stack trace looks something like this: Thread 14 (Thread 0x7fffbd7fa6c0 (LWP 255122) "KIO::WorkerThre"): #0 stat (pathname=0x7fff9c00abe8 "/home/chenxiaolong", statbuf=0x7fffbd7f9780) at slow_stat.cpp:35 #1 0x00007ffff6f16646 in acl_get_file (path_p=0x7fff9c00abe8 "/home/chenxiaolong", type=16384) at libacl/acl_get_file.c:73 #2 0x00007fffd80be93e in createUDSEntry(QString const&, QByteArray const&, KIO::UDSEntry&, QFlags<KIO::StatDetail>, QString const&) [clone .lto_priv.0] () from /usr/lib64/qt5/plugins/kf5/kio/kio_file.so #3 0x00007fffd80c64c6 in FileProtocol::stat(QUrl const&) () from /usr/lib64/qt5/plugins/kf5/kio/kio_file.so #4 0x00007ffff790ff15 in KIO::SlaveBase::dispatch(int, QByteArray const&) () from /lib64/libKF5KIOCore.so.5 #5 0x00007ffff790869e in KIO::SlaveBase::dispatchLoop() () from /lib64/libKF5KIOCore.so.5 #6 0x00007ffff7983553 in KIO::WorkerThread::run() () from /lib64/libKF5KIOCore.so.5 #7 0x00007ffff5ae8507 in QThreadPrivate::start (arg=0x555555683ff0) at thread/qthread_unix.cpp:330 #8 0x00007ffff54ae12d in start_thread (arg=<optimized out>) at pthread_create.c:442 #9 0x00007ffff552fbc0 in clone3 () at ../sysdeps/unix/sysv/linux/x86_64/clone3.S:81 Since the UI is freezing despite the slow stat calls being on another thread, I'm assuming there's a StatJob::exec()/KJob::exec() call somewhere forcing the UI to wait for its completion. Unfortunately, I've had no luck at all tracking down where the job came from. -- You are receiving this mail because: You are watching all bug changes.
