A optional panel plugin would allow those, who like to keep their systems uptodate, gain "realtime" notification of any updates and those who dont really care about it one way or another would not need to bother about installing it. Practically speaking, a cron job that fired up the daemon to run the checks every six hours or so would be more than adequate given the normal rate of updates. The plugin would be configured to point at a particular mirror, thus allowing for the existence of two plugins;one pointing to current, the other to snapshot. Given these plugins dont actually do any installations themselves, they simply give you a heads up about what is changing in the repositories. An RSS feed could do the same, but I rather like the idea of a flashing dolphin plugin, but perhaps thats just me .

Well, After reading some posts. I've decided to make up the silly critics I made there before by creating something that try to address the issues.

autoUpdate.pl

----------------------

Version 0.7.5

*Use timestamps to reduce network traffic and cputime doing "netpkg list U"
*Minor big fix
*This version require libwww-perl installed, please install it from netpkg
*Fix the issue with updated GDM package.
*Fix the compatibility with ktsuss

----------------------

Well, This little program does NOT update anything for you, instead it does certain things inspired by the quote above (well, the flashing icon hasn't been implemented yet ...

) Currently, it checks the default ZW repo you pointed to and report the total number of updates available. it does the notification by changing icon in the system tray (notification area) :

means network or program error:

right click to get menu (quit)
left click to re-queue (the icon will disappear and popup again 99 seconds later with black_list recheck)

means system up-to-date, the messages will be in tooltips

right click to get menu (quit)
left click to re-queue (the icon will disappear and popup again 99 seconds later with black_list recheck)

If you just leave it there at this stat, it will automatically recheck every 20 minutes.

means there are more then 1 package update available on the repo, the messages will be in the tooltips (it tells you the number of packages available)

right click to get menu (quit)
left click to launch xnetpkg, after that, re-queue ( 10 seconds later, with black_list recheck) the daemon.

If you just leave it there at this stat, it will automatically recheck every 60 minutes.

Since version 0.4, the "Black_list" tag in netpkg.conf get checked and memorized at startup, during the process the program uses the same list until you left click the icon and make it "re-queue" (the icon disappear). The black_list get detected again in this mode. I think this is a better way to improve performance since that most people don't change their "Black_list" tag too often. However, if you do change the "Black_list", just left click the tray icon, autoUpdate will detect your changes.

Installation

I'll make it a ZW package in the future, but actually it's quite easy to install. All dependencies should be solved on the default ZW installation disc.
Just copy the perl script (make sure you have permission to execute it) to any folder in root's path. You have two ways to execute the script,

option A) Launch the script as root, point the screen to the right place:

Code:

DISPLAY=:0.0 autoUpdate.pl &

option B) (currently the better way to install) Allow gksudo execution of the script:

for example, if I (infwonder) installed the script in /usr/sbin,
add the line as root with command "visudo", it will bring up vi to edit the sudo config file:

Code:

infwonder ALL = (ALL) /usr/sbin/autoUpdate.pl

Then you can launch the program with the command of:

Code:

gksudo /usr/sbin/autoUpdate.pl

NOTE

This version of the code may still have bugs, please report bugs to me

Helps for GTK2-perl (or just GTK2) programming are appreciated.

Thanks for helps from all the testers $\!D/$

.

Stickied it.

a really nice add might be an option (conf file like "pkg1,pkg4,pkg42" maybe [1]) to avoid some package.
This way ones don't get "there is some package to update" and the only package to update are package the user don't wan't to update (blacklisted ones).

BTW you should create a package ...

[1]Or maybe parsing netpkg.conf "Black_list" tag

yeah, I've done some work about that. Now I am trying to optimize it for better performance.

Stay tune for a new version (and maybe a zenwalk package ?!? )

please put the lock in: /var/run/autoupdate.lock
and about the Black_list, you might replace line 60:

Code:

chomp($list = `nice -19 netpkg list U|nice -19 grep --mmap -o -c "\[U\]" &`) && &listing;

with:

Code:

$blacklistpkgs=`nice -19 grep Black_list /etc/netpkg.conf | sed 's/.*=\s//g; s/\s/|/g'`
chomp($list = `nice -19 netpkg list U|nice -19 grep --mmap -o -c "\[U\]" |nice -19 grep -E "$blacklistpkgs" &`) && &listing;

Thank you, guth, for your advices.

However, before I read your post, I've already done a new version that resolve black_list issue. Please take a look and give it a try.

The lock file is now placed at /var/run

Hope you like my solution as well!

waitting for package ....

infwonder · **Posted:** Thu Sep 27, 2007 3:36 pm

I think we need more tests before making it a ZW package. I am now trying to run it 24/7 on different machines and see what will happen. Please help me test the script and report bugs to me.

Thank you in advance.

creating a ZW package doesn't mean perfect software, it just means:
- easier to use (with a nice .desktop)
- easier to install/upgrade

infwonder · **Posted:** Thu Sep 27, 2007 5:31 pm

I see.
But I have one more question about making this into a package:

If I follow the installation mentioned above in my package, which requires me to modified /etc/sudoers. Is this ok ? I saw that /etc/sudoers is in the "protected_files" section in netpkg.conf, does this mean the .old files will be shift back when the package uninstall ?

Maybe using SUID on this script is a better solution? What do you think?

Thnk you in advance !

H!!!

you might create a doinst.sh with a content like:

Code:

isalreadyhere=$(grep autoUpdate /etc/sudoers);
if [ -z "$isalreadyhere" ]; then
    cp /etc/sudoers /etc/sudoers.new
    echo "%cdrom ALL = (root) NOPASSWD: /usr/sbin/autoUpdate.pl " >> /etc/sudoers.new
fi

not tested but i guess you got the idea

infwonder · **Posted:** Sun Sep 30, 2007 7:53 am

sorry, guth, I 've tried your suggestion and built a package for ZUT, but after installation (with zenpkg), when I do "dotnew", the sudoers.new didn't showup in the list. Is this because I didn't install the package through netpkg? or should I change the "protected_Files" tag ? What should I do to allow the modified /etc/sudoers.new be detected by netpkg dotnew ?

Thank you in advance

H!!!

Reporting: the thing works with kde... I seem to have two upgradable packages....

Some remarks:

- the util reports two upgradable packages, but netpkg has a different view of things it has more
than those, and not all of those are blacklisted... (do you want details?)
- if i click on the icon, netpkg starts, but the icon 'disappears' once netpkg is running/stopped...

Probably due to my incompetence.... I started the app from a root-console...
