After a bunch of "portmaster -a" runs, the pkgng sqlite database appears to get corrupted. For example, when I try to update an existing port, this happens: > > root@five:~ # portmaster ports-mgmt/pkg > ... > ===> Registering installation for pkg-1.0.11 > Installing pkg-1.0.11...pkg: sqlite: database disk image is malformed (pkgdb.c:925) > pkg: sqlite: database disk image is malformed (pkgdb.c:1914) > *** [fake-pkg] Error code 70 > > I have removed all ports and the pkgng databases and reinstalled, but the corruption seems to return after a few days or weeks of installing and deinstalling ports. > > On another system that has a disk, that corruption of the pkgng database has not happened over six months or so. I therefore wonder if storing the sqlite database on an NFS-mount is triggering some sort of bug, either in pkgng or in newnfs. AFAIK, pkgng is using locks on the database quite liberally, could that be where a bug is lurking? > > I'm happy to help debug this, but someone would need to let me know what to try. > This can usually happen when a user do not have the nfs lock system started. Are you sure that nfs lock is correctly started? If that is the case, there is anyway a bug in pkgng that should catch the problem and refuse to operate in such situation, I know sqlite to provide a mechanism that allow us to be able to catch this, I'm not sure yet to use it. regards, Bapt [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAlFlHJMACgkQ8kTtMUmk6ExhmgCcDbFXtRAI6FZ45NUoB4CbE27s kloAn0umPTBIWw625ZXY1XfuvTbhyyFF =2iLX -----END PGP SIGNATURE-----
