SQLiteJournal: filesystem permissions like ordinary file

[milo]

SQLiteJournal is used with the FileCache. Seems correct to me, it should behave in the same way as ordinary files.

I didn't find a more systematic way.

I don't like the is_file call but I don't have a better solution.

What about

if ($path !== ':memory:') {
    touch($path);
}

[JanTvrdik]

@Unlink 👍 for touch

EDIT: or maybe not, I don't know.

What if fopen returns false?

[milo]

Good point.

Syscalls of solutions:

# touch() - first
access("/tmp/file.touch", F_OK)         = -1 ENOENT (No such file or directory)
open("/tmp/file.touch", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
close(4)                                = 0
utime("/tmp/file.touch", NULL)

# touch() - every next
access("/tmp/file.touch", F_OK)         = 0
utime("/tmp/file.touch", NULL)          = 0


# is_file() - first
stat("/tmp/file.touch", 0x7fff3333d540) = -1 ENOENT (No such file or directory)
lstat("/tmp/file.touch", 0x7fff3333b330) = -1 ENOENT (No such file or directory)
open("/tmp/file.touch", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4

# is_file() - every next
stat("/tmp/file.touch", {st_mode=S_IFREG|0660, st_size=0, ...}) = 0

What about !is_file + touch.
