As root

Install the required packages:

# yum install pulseaudio-module-jack alsa-plugins-jack jack-audio-connection-kit 

Add yourself to the pulse-rt and jackuser  group.

# usermod -a -G pulse-rt,jackuser "<your username>"

Edit /etc/security/limits.conf:

@jackuser - rtprio 20
@jackuser - memlock 4194304
@pulse-rt - rtprio 20
@pulse-rt - nice -20

As your normal user

Create the pulseaudio start file ~/jack.pa:

#!/usr/bin/pulseaudio -nF
#
load-module module-jack-sink
load-module module-jack-source

load-module module-native-protocol-unix
load-module module-volume-restore
load-module module-default-device-restore
load-module module-rescue-streams
load-module module-suspend-on-idle
.ifexists module-gconf.so
.nofail
load-module module-gconf
.fail
.endif
.ifexists module-x11-publish.so
.nofail
load-module module-x11-publish
.fail
.endif

Relog to get the new group permissions and limits.

Kill the current pulseaudio daemon:

$ killall pulseaudio

Start the jack daemon (your parameters may be different):

$ jackd -R -P4 -dalsa -r44100 -p512 -n4 -D -Chw:0 -Phw:0

Start the pulseaudio daemon:

$ pulseaudio -nF ~/jack.pa

Now everything should work :) At least for me it does.

What next? See Professional audio with Fedora and join the Fedora AudioCreation SIG.

These bootcharts were taken one the same machine (smolt hardware profile).

Note: All distributions were measured after their default installation and after a quick optimization. You may gain less boot time by doing further optimization, but I did not want to get into detail for every distribution. I just turned off all unneeded services, to basically have a networked workstation, with which you can browse the internet.

To compare the distributions, the time measured until the X-Server is starting is displayed in the table. In parantheses, you see a manual measured time from grub prompt to gdm login prompt, which basically defines the user experience.

Conclusions

• kernel+nash boot time has a good potential to be optimized in Fedora (pre F10)
  
• a good readahead can improve service starting vastly (see Ubuntu), Fedora's readahead (pre F10) slows down.
  
• early, parallel login can fool the users perception of boot time
• rhgb is slow for Fedore <= 8
  
• the less services started, the faster it boots (so obvious :-)

The final class with an extension for __setstate__ and __getstate__ can be found here: transaction.py and transaction_test.py.

Also now in the ASPN Python Cookbook as http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/551788

Now to the story, that led to it:

I have the need for a transaction class in python. Browsing the python cookbook led me to a small Transaction class

$ python
Python 2.5.1 (r251:54863, Oct 30 2007, 13:45:26) 
[GCC 4.1.2 20070925 (Red Hat 4.1.2-33)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> class Transaction(object):
...     def __init__(self):
...         self.log = []
...     def commit(self):
...         self.log.append(self.__dict__.copy())
...     def rollback(self):
...         try:
...             self.__dict__.update(self.log.pop(-1))
...         except IndexError:
...             pass
... 

Ok, lets have some fun with it.

>>> class A(Transaction):
...     pass
... 
>>> a = A()
>>> a.test = True
>>> a.commit()
>>> a.test = False
>>> a
'self.__dict__ = {'test': False, 'log': [{'test': True, 'log': [...]}]}'
>>> a.rollback()
>>> a
'self.__dict__ = {'test': True, 'log': []}'

Nice. Let's see if we can commit and rollback several times.

>>> a = A()
>>> a.test = 1
>>> a.commit()
>>> a.test = 2
>>> a.commit()
>>> a.test = 3
>>> a
'self.__dict__ = {'test': 3, 'log': [{'test': 1, 'log': [...]}, {'test': 2, 'log': [...]}]}'
>>> a.rollback()
>>> a
'self.__dict__ = {'test': 2, 'log': [{'test': 1, 'log': [...]}]}'
>>> a.rollback()
>>> a
'self.__dict__ = {'test': 1, 'log': []}'

Ok.. works :) Let's try some lists.

>>> a = A()
>>> a.test = [ 0, 1 ]
>>> a.commit()
>>> a.test.append(2)
>>> a
'self.__dict__ = {'test': [0, 1, 2], 'log': [{'test': [0, 1, 2], 'log': [...]}]}'
>>> a.rollback()
>>> a
'self.__dict__ = {'test': [0, 1, 2], 'log': []}'

Doh! Ok, someone mentioned that already in the comments. copy.deepcopy() is the key.

>>> import copy
>>> 
>>> class Transaction2(Transaction):
...     def commit(self, **kwargs):
...         self.log.append(copy.deepcopy(self.__dict__))
... 
>>> class A(Transaction2):
...     pass
... 
>>> a = A()
>>> a.test = [ 0, 1 ]
>>> a.commit()
>>> a.test.append(2)
>>> a
'self.__dict__ = {'test': [0, 1, 2], 'log': [{'test': [0, 1], 'log': []}]}'
>>> a.rollback()
>>> a
'self.__dict__ = {'test': [0, 1], 'log': []}'

Ah, works. Very good. Now another check:

>>> a = A()
>>> a.test = 1
>>> a.commit()
>>> a
'self.__dict__ = {'test': 1, 'log': [{'test': 1, 'log': []}]}'
>>> a.other = 2
>>> a
'self.__dict__ = {'test': 1, 'other': 2, 'log': [{'test': 1, 'log': []}]}'
>>> a.rollback()
>>> a
'self.__dict__ = {'test': 1, 'other': 2, 'log': []}'
>>> a.other
2

Oh, a leftover... seems like self.__dict__ has to be cleared, before the update.

>>> class Transaction3(Transaction2):
...     def rollback(self, **kwargs):
...         try:
...             state = self.log.pop(-1)
...             self.__dict__.clear()
...             self.__dict__.update(state)
...         except IndexError:
...             pass
... 
>>> class A(Transaction3):
...     pass
... 
>>> a = A()
>>> a.test = 1
>>> a.commit()
>>> a
'self.__dict__ = {'test': 1, 'log': [{'test': 1, 'log': []}]}'
>>> a.other = 2
>>> a
'self.__dict__ = {'test': 1, 'other': 2, 'log': [{'test': 1, 'log': []}]}'
>>> a.rollback()
>>> a
'self.__dict__ = {'test': 1, 'log': []}'
>>> a.other
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'A' object has no attribute 'other'
>>>

Ah, works. Very good. Ok, more tests...

>>> b = a.ncls 
>>> a.ncls.test = True
>>> a.commit()
>>> a.ncls.test = False
>>> a.rollback()
>>> a
'self.__dict__ = {'ncls': 'self.__dict__ = {'test': True, 'log': []}', 'log': []}'
>>> b
'self.__dict__ = {'test': False, 'log': []}'

Oh, what if we work with "b", which stills holds the old value? Maybe we should commit() all our attributes also, traversing through them all?

Ok, here is such a beast:

>>> class TransactionNew1(object):           
...     def _docommit(self):
...         if "log" not in self.__dict__:
...             self.__dict__["log"] = list()
...             
...         self.__dict__["log"].append(copy.deepcopy(self.__dict__))
...     
...     def _dorollback(self):
...         if "log" not in self.__dict__:
...             return
...         try:
...             state = self.__dict__["log"].pop(-1)
...             self.__dict__.clear()
...             self.__dict__.update(state)
...         except IndexError:
...             pass
...     
...     def commit(self, **kwargs):
...         # commit ourselves, then our childs
...         self._docommit()
...         if kwargs.get("deep", True):
...             for child in self.__dict__.values():
...                 if isinstance(child, self.__class__):
...                     child.commit()
...                     
...     def rollback(self, **kwargs):
...         # rollback our childs, then ourselves
...         if kwargs.get("deep", True):
...             for child in self.__dict__.values():
...                 if isinstance(child, self.__class__):
...                     child.rollback()
...         self._dorollback()
...     
...     def __repr__(self):
...         return "'self.__dict__ = %s'" % self.__dict__
... 
>>> class A(TransactionNew1):
...     pass
... 
>>> a = A()
>>> a.ncls = A()
>>> b = a.ncls 
>>> a.ncls.test = True
>>> a.commit()
>>> a.ncls.test = False
>>> a.rollback()
>>> a
'self.__dict__ = {'ncls': 'self.__dict__ = {'test': True}', 'log': []}'
>>> b
'self.__dict__ = {'test': True, 'log': []}'

Ok... looks good, but  we lost the reference. id(b) != id(a.ncls) ... ( update: this is fixed in the final version )

Working with it revealed also:

>>> a = A()
>>> b = a
>>> for i in xrange(3):
...     b.n = A()
...     b.t = "test"
...     b = b.n
...     a.commit()
... 
>>> a
'self.__dict__ = {'log': [{'n': 'self.__dict__ = {}', 'log': [], 't': 'test'}, {'n': 'self.__dict__ = {'log': [{'log': []}], 't': 'test', 'n': 'self.__dict__ = {}'}', 'log': [{'t': 'test', 'log': [], 'n': 'self.__dict__ = {}'}], 't': 'test'}, {'n': 'self.__dict__ = {'log': [{'log': []}, {'log': [{'log': []}], 't': 'test', 'n': 'self.__dict__ = {}'}], 't': 'test', 'n': 'self.__dict__ = {'log': [{'log': []}], 't': 'test', 'n': 'self.__dict__ = {}'}'}', 'log': [{'t': 'test', 'log': [], 'n': 'self.__dict__ = {}'}, {'t': 'test', 'log': [{'n': 'self.__dict__ = {}', 't': 'test', 'log': []}], 'n': 'self.__dict__ = {'t': 'test', 'log': [{'log': []}], 'n': 'self.__dict__ = {}'}'}], 't': 'test'}], 't': 'test', 'n': 'self.__dict__ = {'t': 'test', 'log': [{'log': []}, {'n': 'self.__dict__ = {}', 't': 'test', 'log': [{'log': []}]}, {'n': 'self.__dict__ = {'log': [{'log': []}], 't': 'test', 'n': 'self.__dict__ = {}'}', 't': 'test', 'log': [{'log': []}, {'log': [{'log': []}], 't': 'test', 'n': 'self.__dict__ = {}'}]}], 'n': 'self.__dict__ = {'t': 'test', 'log': [{'log': []}, {'n': 'self.__dict__ = {}', 't': 'test', 'log': [{'log': []}]}], 'n': 'self.__dict__ = {'log': [{'log': []}]}'}'}'}'
>>> len(str(a))
1192

Hmm... seems strange.. Ah, self.log was also copied with copy.deepcopy(). So, we have multiple useless copies. Let's "pop()" the state from self.__dict__ before the deepcopy.

>>> class TransactionNew2(TransactionNew1):
...     def _docommit(self):
...         if "log" in self.__dict__:
...             oldstate = self.__dict__.pop("log")
...         else:
...             oldstate = None             
...         state = copy.deepcopy(self.__dict__)
...         if oldstate:
...             state["log"] = oldstate
...         self.__dict__["log"] = state
...     def _dorollback(self):
...         if "log" not in self.__dict__:
...             return
...         try:
...             state = self.__dict__["log"]
...             self.__dict__.clear()
...             self.__dict__.update(state)
...         except IndexError:
...             pass
... 
>>> class A(TransactionNew2):
...     pass
... 
>>> 
>>> a = A()
>>> b = a
>>> for i in xrange(3):
...     b.n = A()
...     b.t = "test"
...     b = b.n
...     a.commit()
... 
>>> a
'self.__dict__ = {'log': {'log': {'log': {'t': 'test', 'n': 'self.__dict__ = {}'}, 't': 'test', 'n': 'self.__dict__ = {'log': {}, 't': 'test', 'n': 'self.__dict__ = {}'}'}, 't': 'test', 'n': 'self.__dict__ = {'log': {'t': 'test', 'n': 'self.__dict__ = {}'}, 't': 'test', 'n': 'self.__dict__ = {'log': {}, 't': 'test', 'n': 'self.__dict__ = {}'}'}'}, 't': 'test', 'n': 'self.__dict__ = {'t': 'test', 'log': {'log': {'t': 'test', 'n': 'self.__dict__ = {}'}, 't': 'test', 'n': 'self.__dict__ = {'log': {}, 't': 'test', 'n': 'self.__dict__ = {}'}'}, 'n': 'self.__dict__ = {'t': 'test', 'log': {'t': 'test', 'n': 'self.__dict__ = {}'}, 'n': 'self.__dict__ = {'log': {}}'}'}'}'
>>> len(str(a))
671

Ok, saved us a bit of state length.  The final version has:

>>> a
'self.__dict__ = {'__l': {'__l': {'__l': {'t': 'test'}, 't': 'test'}, 't': 'test'}, 't': 'test', 'n': 'self.__dict__ = {'__l': {'__l': {'t': 'test'}, 't': 'test'}, 't': 'test', 'n': 'self.__dict__ = {'__l': {'t': 'test'}, 't': 'test', 'n': 'self.__dict__ = {'__l': {}}'}'}'}'
>>> len(str(a))
275

Now another thing:

>>> a = A()
>>> a.n = a
>>> a.commit()

  File "/usr/lib64/python2.5/copy.py", line 162, in deepcopy
    y = copier(x, memo)
RuntimeError: maximum recursion depth exceeded

... Oh, oh! Recursion in commit()... Now we have to check, if we have been there.

>>> class TransactionNew3(TransactionNew2):
...     def _checksetseen(self, seen):
...         if id(self) in seen:
...             import sys

The final class with an extension for __setstate__ and __getstate__ can be found in the Related content section below. Have fun with it :-)

$ pilot-xfer -p usb: -l

instead of the command with a kludgy /dev/pilot symlink

$ pilot-xfer -p /dev/pilot -l

fails because the USB device does not have the right permissions. With the introduction of PolicyKit and ACLs for console users in Fedora 8, we can now solve the problem in the right way.

First we create a policy type pda by creating the file /usr/share/hal/fdi/policy/10osvendor/19-palm-acl-management.fdi

# cat > /usr/share/hal/fdi/policy/10osvendor/19-palm-acl-management.fdi <<EOF
<?xml version="1.0" encoding="UTF-8"?>

<deviceinfo version="0.2">
  <device>
    <match key="info.capabilities" contains="pda">
      <match key="pda.platform" string="palm">
        <append key="info.capabilities" type="strlist">access_control</append>
        <merge key="access_control.type" type="string">pda</merge>
        <merge key="access_control.file" type="copy_property">pda.palm.hotsync_interface</merge>
      </match>
    </match>
  </device>
</deviceinfo>
EOF

Now, we have to assign this policy to the device nodes of a device. This can be done by creating policies which look like:

   <match key="usb_device.vendor_id" int="0x082d">
      <match key="usb_device.product_id" int="0x0100">
          <append key="info.capabilities" type="strlist">pda</append>
          <merge key="pda.platform" type="string">palm</merge>
          <merge key="pda.palm.hotsync_interface" type="copy_property">linux.device_file</merge>
      </match>
   </match>

An example of /usr/share/hal/fdi/policy/10osvendor/20-pda-acl-management.fdi can be installed by:

# wget -O /usr/share/hal/fdi/information/20thirdparty/10-usb-pda-palm.fdi  'https://bugzilla.redhat.com/attachment.cgi?id=294520'

Finally we prevent the "visor" module to be automatically loaded by creating the file /etc/modprobe.d/blacklist-visor, because the visor module would take over the USB device and make it a serial ttyUSB.

# echo 'blacklist visor' > /etc/modprobe.d/blacklist-visor

Now you want to restart HAL and remove the visor module:

# service haldaemon restart
# rmmod visor

With all these files in place, we can now do the

$ pilot-xfer -p usb: -l

as a normal user. That's it. No hacky udev rule involved. This example can be applied to any other device which should be accessible by a console user.

The way I read man PolicyKit.conf, it is even possible to grant access to specific groups and users permanently.

Happy Syncing!

Update: Active development also in https://bugzilla.redhat.com/show_bug.cgi?id=280251#c120

Not working? Read the checklist.

Bootchart

Boot time: 35s

Incredible speed, I must admit. Time to look at Fedora.

Fedora 8 Test 3 - Default Installation - SELinux off

Bootchart

Boot time: 73s

Default Installtion, SELinux turned off. Wow, that's disappointing for the average Desktop user. Let see, why it is so slow.

Fedora 8 Test 3 - Same Services - SELinux off

Bootchart

Boot time: 46s

Turning off all the services, which are not started by default on the openSUSE, the boot time is nearly comparable now.

The following services are only started:

• iptables
• network
• irqbalance
• rsyslog
• auditd
• cpuspeed
• messagebus
• rpcbind
• rpcidmapd
• nscd
• sshd
• ConsoleKit
• crond
• atd
• avahi-daemon
• cups
• haldaemon
• anacron
• NetworkManager
• NetworkManagerDispatcher

Fedora 8 Test 3 - Same Services - SELinux off - No rhgb

Bootchart

Boot time: 38s

Switching off rhgb saves 8s. Wow, that is much, compared to the whole boot process without the kernel time.

Fedora 8 Test 3 - Same Services - SELinux off - No rhgb - prcsys

Bootchart

Boot time: 34s

By installing prcsys, adding missing LSB Headers to the services, it is now less boot time than openSUSE. Hurray! :-)

Fedora 8 Test 3 - Same Services - SELinux off - No rhgb - prcsys - No Floppy module

Bootchart

Boot time: 32s

Removing /etc/sysconfig/modules/udev-stw.modules, which basically only loads the floppy module, because floppies are not autoloaded just saved me 2 seconds. I have no floppy on my machine, so that was only probing on my machine. Time to think of another mechanism of loading this module or not.

Update:

alias pnp:dPNP0700 floppy

This may do the trick in modprobe.conf. Maybe that should be a modalias in the floppy module.

Fedora 8 Test 3 - Same Services - SELinux on - No rhgb - prcsys - No Floppy module

Bootchart

Boot time: 37s

To see how much SELinux would slow down, I turned selinux on, relabled and rebooted.

For the reference, I uploaded the Machine Profile to Smolt

system-config-network

A network configuration tool, supporting Ethernet, Wireless, TokenRing, ADSL, ISDN and PPP.

system-config-boot

system-config-boot is a graphical user interface that allows the user to change the default boot entry of the linux system (grub).

dldialog

 DLDialog offers the capability to draw a variety of widgets. It includes a definition language similar to Tcl/Tk. It can display dialogs the tvision/ncurses interface or using graphical windows with the QT/X11 interface.

Not developed anymore.

autorun

autorun automagically recognizes all available CDROMs in the system, mounts them upon insertion of a media and executes a possible autorun executable on the CD. The user can remove the media; autorun will call unmount.

Obsolete with todays desktops.

This script can be called in /etc/ppp/ip-up.local with

or within a shell

iptables

Now we can route traffic through the various priority classes with iptables.

• put my CIPE connection to high priority
  1. iptables -t mangle -A POSTROUTING -d 192.168.1.201 -p udp -m udp --dport 7777 -j MARK --set-mark 0x1
• put traffic to a specific host in class 2
  1. iptables -t mangle -A POSTROUTING -p tcp -m tcp -d 192.168.1.200 -j MARK --set-mark 0x2
  2. iptables -t mangle -A POSTROUTING -p udp -m udp -d 192.168.1.200 -j MARK --set-mark 0x2
• put imap ssl and http to class 2
  1. iptables -t mangle -A POSTROUTING -p tcp -m tcp --dport 993 -j MARK --set-mark 0x2
  2. iptables -t mangle -A POSTROUTING -p tcp -m tcp --dport 80 -j MARK --set-mark 0x2

Debugging

nice debugging tools are:

 # watch -n 1  /sbin/tc -s -d class show dev $DEV
 # watch -n 1 -d /sbin/iptables -t mangle -nvL
 # iptraf

To see the difference, just turn off traffic control:

  # /sbin/tc qdisc del dev $DEV root

Configuration

Configure File sync

Now lets configure multisync. In this example we will sync the phone against a directory called “sync” in our home directory. If you want to configure an evolution sync instead skip this part, and go straight to the evolution configuration.

$ cd
$ mkdir sync
$ msynctool --addgroup filenokia
$ msynctool --addmember filenokia file-sync
$ msynctool --addmember filenokia syncml-obex-client

In order to continue we need some Infos from our phone. First of all we need to find out the bluetooth address of our phone:

$ hcitool scan
Scanning ...
XX:XX:XX:XX:XX:XX MYPHONENAME

As you may guess the value represented by XX:XX:XX:XX:XX:XX is your phones address. Now we need the channel on which the service called “SyncMLClient” is running:

$ sdptool browse XX:XX:XX:XX:XX:XX

This command will return a lot of information. Look for something like this:

Service Name: SyncMLClient
Service RecHandle: 0x10003
Service Class ID List: "Error: This is UUID-128" (0x00000002-0000-1000-8000-0002ee000002)
Protocol Descriptor List: "L2CAP" (0x0100) "RFCOMM" (0x0003)
Channel: 11 "OBEX" (0x0008)
Language Base Attr List: code_ISO639: 0x454e encoding: 0x6a base_offset: 0x100
Profile Descriptor List: "Error: This is UUID-128" (0x00000002-0000-1000-8000-0002ee000002)
Version: 0x0100

As you can see in my case the needed channel was channel 11. Now we have everything we need. so there just a few steps left:

$ msynctool --configure filenokia 1

This will open a vi instance, where you need to input this:

<config>
<path>/home/USERNAME/sync</path>
<recursive>FALSE</recursive>
</config>

Now we just need to configure the syncml-client:

$ msynctool --configure filenokia 2

Again a vi instance will open. This time you need this:

<config>
<bluetooth_address>XX:XX:XX:XX:XX:XX</bluetooth_address>
<bluetooth_channel>YY</bluetooth_channel>
<identifier>PC Suite</identifier>
<version>1</version>
<wbxml>1</wbxml>
<username></username>
<password></password>
<type>2</type>
<usestringtable>1</usestringtable>
<onlyreplace>0</onlyreplace>
<recvLimit>10000</recvLimit>
<maxObjSize>0</maxObjSize>
<contact_db>Contacts</contact_db>
<calendar_db>Calendar</calendar_db>
<note_db>Notes</note_db>
</config>

You just need to replace XX:XX:XX:XX:XX:XX with your bluetooth address and YY with your channel. Nothing more is necessary to sync against a file. The following part describes the configuration for an evolution sync.

Configure Evolution sync

The procedure is almost the same as above. There are just some slight modifications. First of all you should name your group differently. Here we will use “evo2nokia” instead of “filenokia”. Before beginning the opensync coniguration you should make sureTherefore the first steps should be these:

$ msynctool --addgroup evo2nokia
$ msynctool --addmember evo2nokia evo2-sync
$ msynctool --addmember evo2nokia syncml-obex-client

Now we need to configure the evo2-sync plugin:

$ msynctool --configure evo2nokia 1

Enter the follwoing into the opening editor:

<config>
<address_path>default</address_path>
<calendar_path>default</calendar_path>
<tasks_path>default</tasks_path>
</config>

Next we need to configure the syncml side of the group:

$ msynctool --configure evo2nokia 2

We can use the same configuration as above.

Synchronization

That’s it, now you can sync your phone:

$ msynctool --sync filenokia

or if you configured opensync for evolution synchronization:

$ msynctool --sync evo2nokia

If you want to sync againt another plugin than the file-sync plugin, you can still use this guide. The configuration is exactly the same except for the fact that you need to add your plugin as a member instead of the file-sync plugin. Of course you also need an apropriate configuration for that plugin. But the syncml part stays the same.
If you don’t have a bluetooth dongle and/or want to use your USB cable for syncing go the syncml-guide and check out the forum at nabble. Also don’t forget to check out the excellent opensync wiki. Here are some links where you can find additional information about how to use your nokia 6630 with a linux box.
