[gentoo-user] oder of files opened by a process

[Al]

Hello,

I want to find out by which file and line the */temp/environment
script is run or sourced.

As a am always interested in a general way to solve something, I ask
if there is a tool, that displays me the order in which  files are
read by a process.

I'm not sure but you may want to check into strace.  It may be what you 
are looking for.

* dev-util/strace
      Available versions:  4.5.18 4.5.19 ~4.5.20 {aio static}
      Homepage:            http://sourceforge.net/projects/strace/
      Description:         A useful diagnostic, instructional, and 
debugging tool

Hope that helps.

strace may do the job in a pinch, but there is almost certainly
something better suited to the task...however I don't know what it is.
You may want to use like this:

$ strace YourScript 2>&1 | grep open

which will run YourScript and print all open() system calls to the
console. You will have to sort through many unrelated calls (such as
reading shared library calls) but it will show the order in which your
script is opening external files. Presumably you could key in on the
relevant files using more grep calls and pipes...

No need to use grep to find the open operations.  strace has a -feopen
option, i.e.

  strace -feopen YourScript

Seconded, most of sysinternals' tools are invaluable when working on a
Windows box.

With regard to temp/environment (assuming you're referring to use in
portage during compiling) this might give you some clues:

grep -R \/environment /usr/lib/portage

I have no ideas on windoze.  I don't have it here and try to stay away 
from it when possible.  I just assumed since you posted on a Linux list 
and there was no mention of windoze in the original post that you were 
looking for a Linux tool.

Can't help you there.  Sorry.

Thanks, it was a good suggestion anyway and I will use it the next

Ooops, I was convinced this was the Gentoo user list.

You know Gentoo != Linux. But there is an intersection.

Gentoo is Linux but it is not windoze.  I have asked a question or two 
on here about windoze, my brother uses it, but I usually make that well 
known so that people know it is not Linux I am asking about.  Gentoo 
Linux and windoze are two separate things.

Maybe I am missing something here.

Gentoo is not Linux. Gentoo is a community and a build tool.

The build tool depends on bash. It does not depend on the Linux kernel.

it is a communtiy deeply founded in the linux camp and your stupid behaviour 
does not sit well with it.

If you ask a windows question, mark it as such. Or you will get added to much 
more killfiles.

That said, try asking questions about profiling linux kernel on a windows 
mailing list. I am sure you will get some very nice and helpfull answers.

Perhaps you'd be better off asking in a Cygwin/Windows forum than a

Again, Gentoo != Linux.

But, you are right to suggest the Cygwin list. I didn't anticipate
that such a tool would depend on the kernel architecture. The posix
layer is there.

The Posix layer doesn't provide an API for what you're asking.

I run Gentoo on the Cygwin layer on Vista to be precise. There is no
Linux kernel.

Others run Gentoo on BSD, on Interix or Irix, where there is no Linux kernel.

I have a build script that needs 12 hours to compile the system
packages on Cygwin including the GCC compiler itself.

Wow.  I never realized that could be done.  Tres geek points for ya.

I think our ignorance is understandable when the first paragraph at
http://www.gentoo.org/main/en/about.xml states quite plainly that:

  What is Gentoo?

  Gentoo is a free operating system based on either Linux or FreeBSD
  that ...

Linux and BSD et al. are pretty much just "Unix" (trademark and IP
arguments aside).

The mind wobbles...

I knew you could run all the underlying stuff (bash, python, gcc,
etc.) on Cygwin, so I guess I shouldn't be too surprised that it's
technically possible to run Gentoo.  I'm still a bit surprised that
anybody actually does it.  I've been using Cygwin for a lot of years,
so I'd be willing to bet that installing IA32-Linux-Gentoo on a
windows-hosted VM is probably easier (though of course not quite the
same thing).

That is outdated since they started to run Gentoo on Irix, Mac, Interix ...

Also Interix has Windows kernel. So Gentoo/Windows is around since a
while. Still Interix is more Unix-like than Cygwin.

It was last sunday, when I manged to compile the last package from my
system list.

However, today I have observed that "emerge -e" draws in a few new
packages that I still havn't compiled yet. I need to solve some issues
for that.  That was the reason for my question.

Once 'emerge -e' works, I will go and publish all that stuff. Then
Gentoo/Cygwin is out in the wild.

I have a vision. That is a USB-stick with a LAMP stack on it. It runs
on any OS (Mac, Windows, Linux). You can plug in, whereever you like
and start working.

Same sources, same version, same data, just different binaries. All
done with the Gentoo build system.

You may replace LAMP by the software of your choice.

I think someone should have mentioned the gentoo/alt project way before in this topic.
This is what Al is trying to improve giving us Cygwin support.
Here's the link, http://www.gentoo.org/proj/en/gentoo-alt/prefix/ (I run a x64-macos Gentoo prefix)

Cheers for your problem Al, maybe try the gentoo-alt ML to avoid all the noise but you sure reach more ppl here.

Gentoo/Windows is more stimulant than Gentoo/BSD I guess, because it

Hiding the fact that you're running it doesn't seem like a very
effective means to that end.  It makes you seem like a troll.

For all I care, he can post windows questions here if he wants, but
posting windows questions without telling us they are windows
questions is going to be counter-productive: it's not going to produce
useful answers, and it's going to annoy people (some of whom might
actually have known the answer to the question been clearly stated).

There are projects to port portage and other system tools to all sorts
of other kernels: http://en.wikipedia.org/wiki/Gentoo/Alt

That said, it is quite inaccurate of the OP to claim Gentoo is but a
'build system', and not a Linux. It's primary goal and chief function
as we all know is that of a Linux distro...

Only Gentoo/Linux is Linux. If you run Gentoo on a diffrent kernel it
is still Gentoo, but it is not Linux any more.

If you run GNU on a different kernel it is still GNU, but it is not
Linux any more.

I understand that Al, but you must keep context in mind here. This
mailing list, while perhaps not called the 'gentoo linux users list'
is intended for support for Gentoo Linux. When you post here asking a
question about running Gentoo on cygwin while neglecting to mention
that fact you should not be surprised that some (most) do not know
what you are talking about. At bare minimum you should have disclosed
your rather rare and unique hardware/software environment. At best you
should post to the gentoo-alt ML as Florian suggested. Questions of
semantics aside, 'Gentoo' _is_ Gentoo Linux for probably 95% of users.

I think this list needs to learn, that there are more kernels around
then Linux, even if Gentoo was a Linux Distro originally. Meanwhile it
is developing the only Distro with a super-kernel-realm.

Hey, that's cool man...I'm certainly not telling you not to post here,
I just think it would have been a good idea to post details of your
esoteric setup in the original post. As you've found, the cygwin and
gnu/linux environment(s) are not exactly compatible, and a solution in
one may not work in the other. I'm not even saying it's the way it
should be, but rather that it's the de facto way it is: A very large
majority of people on this list run whitebread 'Gentoo Linux' and as
such, without further clarification in your post, that's what they
think you are running as well....so I don't know, you may have better
results on the specialized gentoo-alt list, but if you want to post
here go ahead...just give us some details :)

You are right in that to enough degree. In this case it would have
been of advantage.

From my experience it is also a reason to strip down my questions to
something as simple as possible. Then I get useful answers. The strace
program, Dale suggests, is a good answer for me. I am not only using
Vista after all. I still can boot Gentoo/Linux to find the answer by
that program.

If I explain the esoteric context, to ask a simple newby question
thereafter, people often give crazy comments and you go without an
answer. Everything out of their horizon is evil for some stubborns.
That is also a real live experience. It is tiresome, if that happens
to often.

I guess you knows this, you ask: How to do this and that ... people
start a political discussion ... why do you want to do this and that?
Time is lost, no answer yet. That is often simply counter productive.

Hence, I became a little conservative with explaining esotric
contexts. But, in this case it was the other way round. I got the
comments, because I didn't explain the context. There isn't a perfect
world. :-)

And how were we to learn that when you didn't tell us you weren't
running Linux/Unix?

I already mentioned it a few times. For simple questions, that don't
look like crossing the borders, I don't mention it any more. It draws
away from the topic.

Probably I need to add something clarifying to my sig:

How about this?

Caution borderliner:  Runnig Gentoo/Prefix on Cygwin/Vista.
All stupid questions are related to this context.

strace fills the bill if you know what process (or its children) you
want to watch, and you can start that process manually.

If you don't know what process you want to watch, or there are a set
of unrelated processes, strace isn't very useful.  In that case you
can use systemtap to monitor open operations on a particular file.

It takes a bit more work to use systemtap than it does to use strace,
but in many ways it's a lot more flexible and powerful:
