Package: mlocate
Version: 0.18-2
Severity: normal
It seems to me updatedb.mlocate is issueing a lot too many calls to
stat64() on /etc/mtab, as seen stracing the process execution.
Ex:
chdir("phalanx") = 0
lstat64(".", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
lstat64("phalanx", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
fchdir(13) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
lstat64("php", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
chdir("php") = 0
lstat64(".", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
lstat64("files", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
fchdir(13) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
lstat64("picocom", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
lstat64("pine", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
lstat64("pivotinit", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
chdir("pivotinit") = 0
lstat64(".", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
lstat64("spitz", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
fchdir(13) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
lstat64("pkgconfig", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
chdir("pkgconfig") = 0
lstat64(".", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
lstat64("pkgconfig-0.15.0", {st_mode=S_IFDIR|0755, st_size=4096, ...}) =
0
write(4, "1.11\0\0configure-uclibc.patch\0\0co"..., 4096) = 4096
fchdir(13) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
lstat64("plinciv", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
chdir("plinciv") = 0
lstat64(".", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
stat64("/etc/mtab", {st_mode=S_IFREG|0644, st_size=842, ...}) = 0
I doubt this is very much necessary and beneficial performance-wise...
On slow machines with lots of files/dirs, updatedb performance
improvements would be very much welcome.
Of course this seems like upstream problem and not specific to Debian.
Hope this helps,
Best regards.
