Very poor read perfomance on OpenSolaris

Hi folks,
I recently upgraded my OpenSolaris server to snv_134 (uname -a: "SunOS opensolaris 5.11 snv_134b i86pc
i386 i86pc Solaris"). I also upgraded netatalk from 2.0.5 to 2.1.5. Since then, I'm experiencing
extremely bad read perfomance. Copying a 9.9MB file from my Mac to the AFP share takes 1.6 seconds, but
copying it back takes 45.4 seconds !

The share is on a ZFS pool, so I had a look whether that might be the issue, but at over 400MB/s the read
performance of the pool is not an issue. I also tried older versions of netatalk (2.1.4, 2.1.1 and 2.0.5),
all showing the same behaviour. Quick debugging via compiling with "-pg" and using gprof didn't help
pinpoint the problem, neither did "truss" (tool like "strace").

I don't know where to start debugging, any pointers at what functions to inspect are appreciated.

Regards,
	Marc

`echo ${HOSTNAME}|cut -d. -f1` is bashism?

Hi,

In case of Ubuntu, ATALK_NAME is empty.
They applying the following patch.

-ATALK_NAME=`echo ${HOSTNAME}|cut -d. -f1`
+ATALK_NAME=`/bin/hostname --short`

Each OS gets the hostname in various methods.

FreeBSD
http://www.freebsd.org/cgi/cvsweb.cgi/ports/net/netatalk/files/netatalk.in?rev=1.3
ATALK_NAME="`/bin/hostname -s`"

SuSE
:BINDIR:/nbprgstr -p 4 `hostname|sed 's/\..*$//'`:Workstation

After all, which method is general?

Afaict it's not a bashism: ${..} variable expansion, `...` command
substition and cut are POSIX compliant.

Because HOSTNAME is not set at the time the netatalk script is called ?

There exists no portable method. Anyway, ATALK_NAME is only used for
Appletalk stuff, isn't it? I'm planning to remove all Appletalk stuff
from Netatalk 3 anyway... ;)

I heard that Ubuntu's sh is symlink to dash, not bash.
It might be spec of dash.

See netatalk-2.1.5/distrib/initscripts/rc.atalk.sysv.tmpl .

| # netatalk.conf expects hostname in $HOSTNAME by default
| HOSTNAME=`hostname`

HOSTNAME seems not to be certain.

problems deleting files with EA's

On netbsd with netatalk-2.1.5 (and 2.1.4 and 2.1.3) on a volume with 
EA support using adouble files (ea:ad), if we try to drag a file that 
has EA's to the trash we get the error:

  The operation can't be completed because one or more
  required items can't be found 
  (Error Code -43)

The original files look like:

-rw-r--r--  1 cliffe  operator  4158131 Jan 11 12:57 
Downloads/ccc-3-1.3.7.dmg
-rw-rw-rw-  1 cliffe  operator  741 Jan 11 12:57 
Downloads/.AppleDouble/ccc-3-1.3.7.dmg
-rw-rw-rw-  1 cliffe  operator   74 Jan 11 12:57

-rw-rw-rw-  1 cliffe  operator   74 Jan 11 12:57

After the error these files remain:

Re: problems deleting files with EA's

Mark,

I'd stay away from ea:ad and use ea:sys.

Mac OS 9 clients? There's no network trash for OS X clients, with OS X
files from network mount get deleted immediately. How comes your
deleted files are in some .Trash folder ?

Its actually ea:auto but that is deciding to use ad

Jan 11 13:45:23.229150 afpd[13859] {volume.c:1907} (W:AFPDaemon):

No this is OS X, the users home directory is a network mount 
so the .Trash is _the_ Trash folder for that user.

So I think there are several issues here:

Looks like the configure is not detecting the extattr support.

Even if it did, I think depending on the underlying filesystem being 
used it may need to be enabled explicitly for a filesystem.

My original report indicates there is some bug in the ea:ad case that 
should be fixed if its going to be offered as an option.

What do I lose if I disable EA  (ea:none)?

cheers

AppleDouble is broken by long fileneme (>255 UTF8-MAC chars)

When a file of a long name is copied from Mac OS X to netatalk,
AppleDouble is broken.
I checked netatalk 2.0.3, 2.0.4, 2.0.5, 2.1.5 and 2.2alpha5.
All results are same.

AFAIR, early Mac OS X have no problem. The copying failed maybe.

I attached a file used to test.
File neme is 127 "ά" chars.

UTF8     : 127*2 = 254 Bytes 
UTF8-MAC : 127*3 = 381 Bytes
UTF16-MAC: 127*4 = 508 Bytes
