43027 2004-02-26 13:39 0000 added DNotify patch back to fam-2.7.0 2004-04-22 00:44:22 0000 1 1 1 Unclassified Gentoo Linux Ebuilds unspecified All Linux RESOLVED FIXED P2 normal --- 1 vslavik@fastmail.fm foser@gentoo.org jackmort@free.fr spider@gentoo.org vslavik@fastmail.fm 2004-02-26 13:39:09 0000 The FAM library can take advantage of Linux's dnotify feature to avoid polling files for changes. It's not part of standard fam distribution, you have to apply a patch. This patch was removed from app-admin/fam in 2.7.0 (2.6.10-r1 had it). There's no mention of it in ChangeLog other than "New release, obsoletes most of the patches", so maybe it was a mistake? Anyway, this patch is pretty important (it improves responsibility), so I took updated patch for 2.7.0 from Debian package and modified the ebuild to apply it. Patches attached, tested & working. Reproducible: Always Steps to Reproduce: vslavik@fastmail.fm 2004-02-26 13:39:43 0000 Created an attachment (id=26426) patch for the ebuild vslavik@fastmail.fm 2004-02-26 13:40:16 0000 Created an attachment (id=26427) fam-2.7.0-dnotify.patch spider@gentoo.org 2004-02-26 13:49:15 0000 Yes, thats correct. However, with DNotify there is another issue in descriptor leakage for removable devices. By not providing the DNotify event tracker in fam there is no longer an issue with this, which is of more importance than the slight boost in responsiveness. vslavik@fastmail.fm 2004-02-26 14:11:51 0000 Are you sure this is still true for 2.7.0 and latest (i.e. this one, Debian's) version of dnotify patch? From Debian's changelog (http://packages.debian.org/changelogs/pool/main/f/fam/fam_2.7.0-5/changelog): """ fam (2.7.0-1) experimental; urgency=low * New upstream release (closes: Bug#224738): - should fix problems with unmounting filesystems with monitored files (closes: Bug#225636) """ Comment #27 at http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=106936 seems to indicate DNotify patch was fixed, too (it's dated 2004-02-04). > which is of more importance than the slight boost in responsiveness. As for "slight", I noticed this because KGhostview's Watch File feature started to react considerably slower (as in immediately vs. something that felt like 1-2 seconds later) after I set up famd. foser@gentoo.org 2004-03-14 14:22:20 0000 ok re-added dnotify support in fam-2.7.0-r1 I indeed couldn't reproduce the old locking problems, but that might also have todo with fixes in other packages. We'll just have to see how it goes. This patch seems quite a bit altered from the original. about 'slight' , fam without monitor polls once p.sec afaik vs almost immediatly now. It looks better, but it doesn't matter that much. jackmort@free.fr 2004-04-21 04:20:01 0000 Here, with fam-2.7.0-r1, I've still the problem with removable devices... foser@gentoo.org 2004-04-21 15:32:45 0000 describe the exact problem & how it is reproducable . I can't reproduce the old problem. jackmort@free.fr 2004-04-22 00:44:22 0000 Well, it's quite simple : In nautilus : - start famd... - mount a floppy/usbkey - access it with nautilus to copy or read some files on it - try to unmount the floppy/usbkey Nautilus complains the device is busy... Try in a term. Same thing. With a lsof, you see that the mount point is beeing monitored by famd... Restart or stop famd : you can unmount. 26426 2004-02-26 13:39 0000 patch for the ebuild fam-2.7.0.ebuild.patch text/plain LS0tIGZhbS0yLjcuMC5lYnVpbGQub3JpZwkyMDA0LTAyLTE1IDIyOjA3OjM5LjAwMDAwMDAwMCAr
