Package: okular
Version: 0.7.1-1
Severity: normal
I was trying to find out why okular what slow to start up and ran strace
on it. I found that even though okular was run from a directory other
than my home directory, for files whose extension was not a known mime
type, open() was called followed by stat64() being called 632 times per
file open()'d:
e.g.
open("/home/amarsh04/FILE_ID.DIZ", O_RDONLY|O_LARGEFILE) = 14
fcntl64(14, F_SETFD, FD_CLOEXEC) = 0
stat64("/home/amarsh04/FILE_ID.DIZ", {st_mode=S_IFREG|0644, st_size=327,
...}) =
0
stat64("/home/amarsh04/FILE_ID.DIZ", {st_mode=S_IFREG|0644, st_size=327,
...}) =
0
fstat64(14, {st_mode=S_IFREG|0644, st_size=327, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xb7
f2d000
_llseek(14, 0, [0], SEEK_SET) = 0
read(14, "F"..., 1) = 1
stat64("/home/amarsh04/FILE_ID.DIZ", {st_mode=S_IFREG|0644, st_size=327,
...}) =
0
read(14, "IDONEWS 08 May 2006 Vol 23 "..., 4096) = 326
read(14, ""..., 4096) = 0
stat64("/home/amarsh04/FILE_ID.DIZ", {st_mode=S_IFREG|0644, st_size=327,
...}) =
0
_llseek(14, 0, [0], SEEK_SET) = 0
read(14, "FIDONEWS 08 May 2006 Vol 23"..., 4096) = 327
read(14, ""..., 4096) = 0
on and on until stat64 had been called 632 times for the one file, then
proceeding on to the next file whose extension wasn't recognised:
stat64("/home/amarsh04/FILE_ID.DIZ", {st_mode=S_IFREG|0644, st_size=327,
...}) =
0
close(14) = 0
munmap(0xb7f2d000, 4096) = 0
open("/home/amarsh04/I-can-spell.denemo", O_RDONLY|O_LARGEFILE) = 14
fcntl64(14, F_SETFD, FD_CLOEXEC) = 0
stat64("/home/amarsh04/I-can-spell.denemo", {st_mode=S_IFREG|0644,
st_size=1392,
...}) = 0
stat64("/home/amarsh04/I-can-spell.denemo", {st_mode=S_IFREG|0644,
st_size=1392,
...}) = 0
fstat64(14, {st_mode=S_IFREG|0644, st_size=1392, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xb7
f2d000
_llseek(14, 0, [0], SEEK_SET) = 0
read(14, "\37"..., 1) = 1
stat64("/home/amarsh04/I-can-spell.denemo", {st_mode=S_IFREG|0644,
st_size=1392,
...}) = 0
and so on through several files.
In running okular from a directory other than my home directory, opening
the file open dialogue, letting it load, then selecting cancel then
quitting okular, (where my home directory has 616 files not starting
with "." and the other directory has 583 files not starting with "."), I
had open() called 878 times and stat64() called 88522 times.
This seems to be an excessive use of stat64().
