[Bismark-devel] time 1.7

[Bismark-devel] time 1.7

[Srikanth Sundaresan]

Does anyone know how to get GNU time 1.7? The current version of time on
the build is incompatible with some of our measurement scripts.

General tip: when trying to figure out where a utility comes from, you 
can generally do a:

$ dpkg --search /usr/bin/time
time: /usr/bin/time

Which in this case shows that ubuntu/debian time comes from the time 
package.

You can then

$ mkdir ~/src/time; cd $_; apt-get source time

to see more about that package and its source.

Anyway...

The version of time in the build is the busybox version, which as you've 
noted is quite limited. It would be a good idea to go through the 
busybox configuration screen and figure out what additional features are 
needed, and what can be dropped. (be gentle here)

In this case, if you really need gnu time,  it would be best to add gnu 
time as an openwrt package,
and then drop the applet from the busybox build after it works. 
Regrettably it is not already packaged up in openwrt.

Alternatively, the busybox folk are good on accepting patches, so you 
could modify busybox to support the syntax for time that you need. As 
src goes, busybox is VERY modular and easy to deal with.

Either way, note this problem in the wiki's issues page. I can see how 
lacking a good timing utility would be a big problem!

[Bismark-devel] [#92] Additional time syntax?

[Dave Taht]

I've captured the issue in the bug database.

Could you document the syntax of time you require?

Re: [Bismark-devel] [#92] Additional time syntax?

[Dave Taht]

I tossed of a quick port of the gnu time utility to the wndr3700, but 
lack the hardware to try it.

get the test binary from:

http://www.teklibre.com/~d/cerowrt/time

and let me know if it works. (you will want to remove the existing 
"time" symlink on your router if it does). Make sure it's measuring 
accurate time...

Secondly, I started at a shared openwrt repository for some new 
packages. github doesn't need any IT resources, and is free for open 
source users, so I used their service.

See https://github.com/dtaht/ceropackages for details

You can do a read-only checkout via

git clone git://github.com/dtaht/ceropackages.git

If you want read/write access, create and/or let me know your account on 
github

You can add the above to your package feeds by editing feeds.conf adding 
this line

src-git cerowrt git://github.com/dtaht/ceropackages.git

then doing a ./scripts/feeds update

I tossed gnu time in there, but it is not fully baked yet, although I 
did a patch to make it compile manually, I didn't figure out how to do 
that right for openwrt. see commit log and Makefile for details.

You can add gnu time to (and break) your existing build by:

./scripts/feeds install time
make menuconfig # add gnu time as a module
make

I'm kind of hoping that having shown this example, someone else will 
take it through the last step of making it into a working package! :)

I just quickly tested it. It seems to be what we want, and also seems to work. Will test it properly with the script and update.

Thanks for the quick response. Was meaning to get back on the syntax email but got tied up with other stuff.

Anything to avoid finishing my taxes.

Well, I'll argue that making busybox's time command more complete would 
be a better option, so
knowing the syntax you need for "time" on this bug report would be good.

But my goal at the moment is to quickly prototype as many of the core 
requirements as possible,
so we know what needs to be done and fixed, and I figure you have a 
major dependency on accurate time.

[Bismark-devel] Coping with email notifications from redmine

[Dave Taht]

If, like me, you get WAY too much email in the first place, you can filter emails from redmine into a separate mailbox
by filtering on the custom email header field

X-Redmine-Project: bismark

or on stuff sent from gburdell.

I usually do the former.

[Nick Feamster]

Thanks. This is cool!

Srikanth: Let me know when (and how) you'd like me to update my openwrt image.  I'm very happy to be your active and passive measurement tester/guinea pig for a home deployment.
