[gentoo-dev] Directory create in ebuilds

[gentoo-dev] Directory create in ebuilds

[Jon Griffin]

I need to create the /etc/logcheck directory and it seems that (sandbox?)
is preventing this. Any help would be appreciated and if I missed it in the
doc please let me know.

Here is the error:

Creating install directory /etc/logcheck
ACCESS DENIED  mkdir:     /etc/logcheck

Re: [gentoo-dev] Directory create in ebuilds

[George Shapovalov]

dodir /etc/logcheck
also please check the contents of /usr/lib/portage/bin/ for what's available 
(such as dobin, dodoc ...).
You should be using these instead of direct mkdir, cp, mv...

Sometimes you may want to do something nonstandsrd or may be some recursive 
task and it may be desireble to do cp -r someplace omeother_place. In any 
case, *do not* perform any such operation on a "live sustem", that is right 
under /usr or whereever. Use ${D}/usr/what/ever instead. ${D} will point to 
the right place, where package gets installed before merging in.
  Also, it would be usefull to read some doc on sandbox'ing. This is mentioned 
in developer docs on gentoo.org, "man emerge" and "man ebuild" should also 
help.

Oops.  Oh well, at least python is easy to read. :)

you can also look at:

man 5 ebuild

_I'll_ volunteer to (re)write it, if someone will give me a boost up the 
learning curve with Python.

I want to write some ebuilds myself, but I lack the time to figure out Python 
cold.  I quit learning (most) new languages about the time object-oriented 
proogramming started up. The explanations of OOP in the early days were... 
cryptic? Obtuse? A tangled bunch of gobbledygook? Something in that general 
direction...    Anyway, I wasn't working as a programmer, so I dropped out of 
the "Language of the Month" club.

What I've seen of Python looks pretty easy, but there are some basic concepts 
I don't have, and trying to reason backward to them from somebody else's code 
hasn't worked too well.

I'd also like to get (and am willing to pay for with documentation of same) 
an explanation of what exactly it is that sandbox does. (And probably a 
couple of other pieces of portage.)

I know it keeps things from messing with the real filesystem, but _how_, 
specifically?  It's much harder to figure out why you're having a problem 
with something when you have no idea what it's doing.

Since quasi-teaching somebody a language via email and such is not real high 
on many people's list of fun things to do, I'll also put in a request for any 
good online tutorials on doing Python. (And if the doc for portage still 
needs to be done once I've mastered it, I'll be willing to help.)

In short, sandbox replaces a number of glibc functions that concern the 
filesystem. Examples of those functions are: fopen, mkdir, link, rename, etc. 
All those functions are replaced with functions that check the place of the 
file in the filesystem, and based on certain environment variables deny or 
allow access to the functions. Because libsandbox.so is put in the 
/lib/ld.so.preload file, all programs run first load this libsandbox before 
anything else. This allows for the replacement of the glibc functions. BTW. 
electric fence for example does the same trick on different functions 
(malloc).

Paul

btw. I don't believe it is nescesarry to understand python to write ebuilds as 
they are written entirely in bash.

I'd also be interested in hearing about any really good Python
tutorials/books for people coming at it fresh and with a very rusty
programming background...grin....

Thanks,
Sean

Well, it took me two seconds to find this:
http://www.python.org/doc/Newbies.html

I can't say if it's of any use though, since it I've only 
brushed the surface of Python myself.

It took me only two seconds as well, but I was looking for some opinions
on quality and approachability.

I can attest to the fact that all the documentation at 
http://www.python.org is most excellent.
