Description of problem: kdiff3 fails to compare huge directories. strace command shows "Too many open files" error. It's probably related to https://bugs.kde.org/show_bug.cgi?id=408991 Version-Release number of selected component (if applicable): kdiff3-1.8.1-1.mga7 How reproducible: $ mkdir d1 d2 $ for ((i=0; i<1500; i++)); do echo az > d1/$i; echo qw > d2/$i; done $ LC_ALL=C strace -e trace=openat kdiff3 d1/ d2/ |& tail -n +2590 openat(AT_FDCWD, "/tmp/d1/997", O_RDONLY|O_CLOEXEC) = -1 EMFILE (Too many open files) openat(AT_FDCWD, "/tmp/d1/998", O_RDONLY|O_CLOEXEC) = -1 EMFILE (Too many open files) openat(AT_FDCWD, "/tmp/d1/999", O_RDONLY|O_CLOEXEC) = -1 EMFILE (Too many open files) openat(AT_FDCWD, "/usr/lib64/qt5/plugins/kf5/FrameworkIntegrationPlugin.so", O_RDONLY|O_CLOEXEC) = -1 EMFILE (Too many open files) ^C
Should be fixed with kdiff3-1.8.1-1.1.mga7 in 7/Core/Updates_testing repo!

It works for me (paths with 12000+ subdirectories and 210000+ files). Thanks. $ cat /etc/mageia-release Mageia release 7 (Official) for x86_64 $ rpm -q kdiff3 kdiff3-1.8.1-1.1.mga7
Assigning to QA, Advisory: ======================== Fix for "Too many open files" bug: Sometimes when doing a kdiff3 between two folders, an error popup appear but this popup is empty and kdiff3 cannot be closed anymore (only solution is to kill it). After a search, it appears the problem comes from the "fastFileComparison" function that opens lots of temporary files but never close them. The fix has been successfully tested on the buggy directories. When printing the "errors" variables of prepareListView, it shows 30 times the messages "Too many open files". For reference: https://phabricator.kde.org/D22294 ======================== Packages in 7/core/updates_testing: ======================== kdiff3-1.8.1-1.1.mga7.i586.rpm kdiff3-1.8.1-1.1.mga7.x86_64.rpm Source RPM: ======================== kdiff3-1.8.1-1.1.mga7.src.rpm
