Recursive Dependency size.
« on: July 27, 2010, 08:06:20 AM »
Is there anything in AppBrowser/AppAudit which will tell me the size of an extention and all of its depedencies? If not does anyone have a script which will do this? I have searched the forums but I couldn't find anything relevant.

Many thanks,

Richard.

Here is a script that will calculate the total size including dependencies.

Updated script, it will now display an indented tree listing of the dependencies
                                                                               
As is, the script will only work on Tiny Core 3.x.   If you want to run it on 2.x, try replacing the 2 lines:
. /etc/init.d/tc-functions
getMirror
                 
With this single line:
MIRROR="http://distro.ibiblio.org/pub/linux/distributions/tinycorelinux/2.x/tcz"

Heh, i was halfway there having tried just "http://distro.ibiblio.org/pub/linux/distributions/tinycorelinux" instead :P

Seems to work fine now with this modification.  :)

Thank you so much for this invaluable tool, this is brilliant!  ;D

I think this will help a lot in taking decisions of installing apps and also might even be of use for discussions in the forum, when now instead of estimating/speculating one could just quickly check total size including all deps. I take it all deps are proceeded recursively.

Ohhh... thank you, gotcha now! ::)

However, i made following observation:
An extension may be listed multiply in proceeding of recursive deps.
A rather random example: When doing "./depsize.sh epiphany.tcz", e.g. gtk2.tcz (and in consequence all its deps) is listed in multiple instances. Haven't made any calculations, but suspecting all instances will be added to total.

Good catch.   I posted a new version that fixes this (and I also dropped the dependency tabbed tree display)

thanks great tool, i have a bug to report :)

your script does not handle KERNEL entries in dep files, you should replace KERNEL with `uname -r`
Code: [Select]
tc@box:~$ ./depinfo lm_sensors.tcz
lm_sensors.tcz                                     size(bytes):     131072
expr: syntax error
hwmon-KERNEL.tcz                                   size(bytes): sh: : invalid number
         0

Total size:  bytes

Thanks for that - this will be very useful in comparing packages.

Works fine here in 2.10, but i note the difference in syntax of deps between extensions of 2.x and 3.x
Code: [Select]

hwmon-2.6.29.1-tinycore.tcz                        size(bytes):     507904

Total size: 13172736 bytes

Would be more readable to display size in kbyte or Mbyte and using thousands separator.

I just use
Code: [Select]
dc $bytes 1024 / p
(where $bytes is number printed on last line of output) to get size in kilobytes.
Quite sure someone with better knowledge than me could manage to grep that number and pipe it to dc.

Thanks for the suggestions.

tinypoodle/bmarkus:  It now shows the size in bytes and megabytes.   Thanks tinypoodle for the "dc" command idea, I used this in the script. 

Arslan S.:   I have fixed the issue with Kernel dependencies. 

I also added in some additional error checking so it will display an error if an extension is not found.

I modified my original posting in this thread with the updated code.

You should be able to work with just the base, use nc (netcat) in place of curl:

Quote
echo -e "HEAD $FILE HTTP/1.0\n" | nc $MIRROR 80

MIRROR being the host name (distro.ibiblio.org), and FILE the full path (/pub/linux/distributions/tinycorelinux/2.x/tcz/firefox.tcz)
The only barriers that can stop you are the ones you create yourself.
