[PATCH RFC 00/13] Collect documention-related tools under tools/doc

[PATCH RFC 00/13] Collect documention-related tools under tools/doc

[Jonathan Corbet]

Our documentation-related tools are spread out over various directories;
several are buried in the scripts/ dumping ground.  That makes them harder
to discover and harder to maintain.

Recently, the idea of creating a dedicated directory for documentation tools
came up; I decided to see what it would look like.  This series creates a
new directory, tools/doc, and moves various utilities there, hopefully
fixing up all of the relevant references in the process.

At the end, rather than move the old, Perl kernel-doc, I simply removed it.

The big elephant lurking in this small room is the home for Python modules;
I left them under scripts/lib, but that is an even less appropriate place
than it was before.  I would propose either tools/python or lib/python;
thoughts on that matter welcome.

This one is the next on my list to convert to Python, but I didn't
do any changes on it yet.

I wonder if the best wouldn't be to have a single script for
features handling all usecases.

Just curious, why does it need to be converted from shell to Python?
I'm sure you will explain that in the patch description (or cover letter).

The rationale is the same as kernel-doc and get-abi: there is a Sphinx
extension that executes it. By converting it into Python and splitting
the code into an exec and a library, we can use the library directly at
the extension.

Besides that, the code in Python, specially after using modules and 
classes, become IMO clearer, making easier to maintain, specially if
we avoid functions inside functions, complex class inheritance, lamba
functions and multiple statements on a single line.

Thanks,
Mauro

This will conflict with my series getting rid of it and touching Makefile.

I prefer if you don't merge this one.

[PATCH 06/13] docs: move get_abi.py to tools/doc

[Jonathan Corbet]

Move this tool out of scripts/ to join the other documentation tools; fix
up a couple of erroneous references in the process.

It's worth noting that this script will fail badly unless one has a
PYTHONPATH referencing scripts/lib/abi.

Heh, on all Python scripts you're moving, you need to change the logic.

In the case of kernel-doc, you need to change from:

	LIB_DIR = "lib/kdoc"
	SRC_DIR = os.path.dirname(os.path.realpath(__file__))		# Currently scripts/
	sys.path.insert(0, os.path.join(SRC_DIR, LIB_DIR))

to:

	LIB_DIR = "../../scripts/lib/kdoc"
	SRC_DIR = os.path.dirname(os.path.realpath(__file__))		# Currently scripts/
	sys.path.insert(0, os.path.join(SRC_DIR, LIB_DIR))

Here, it is the same, except that LIB_DIR will now be:

	LIB_DIR = "../../scripts/lib/abi"

Just in general ... I'm more than happy to put this whole series on the

Ok, thanks! Yeah, this would help avoiding conflicts with the patches
I have piled here.

Btw, as I said I have a /51 patch series focused on parse-headers.pl
and kernel_include.py, which is currently used only by media docs.

For those who don't know, this was added at the very beginning of
Sphinx adoption, and had its own particular way to create *.rst
files from source code with cross references, via an specially crafted
Makefile that runs before Sphinx. This was written as a way to detect
uAPI documentation gaps, producing warnings for unsolved cross references.
Recent Sphinx versions broke it by disabling cross-reference warnings.

This series is big (51 patches) because it needs to fix thousands of
broken cross references on media. I may end splitting it on two series
to make easier for review, one for the script and another for media doc
fixes.

Such series affect this RFC as it is creating a tools/docs and placing 
there the parse-headers.py code as:

	 tools/docs/lib/parse_data_structs.py                                  |  230 +++++++++++++++--------------------
	 tools/docs/parse-headers.py                                           |    5 

Now, if you prefer tools/doc instead and/or place the libs elsewhere,
we have a couple of options:

1. rebase my series to do the changes. I suspect that there won't
   be much conflicts, but this may delay a little bit sending you
   what I have;

2. add a patch at the end moving stuff elsewhere;

3. on your series, move them elsewhere.

What do you prefer?

Thanks,
Mauro

Between "tools/doc" and "tools/docs" I don't really have overly strong
feelings; if you work has the latter we can just stick with that.  If
you propose "tools/Documentation", though, expect resistance :)

As I said, my series was an RFC to see what it would look like; it did't
take all that long the first time around, and will be even quicker to
redo on top of a new base, whatever that turns out to be.

Thanks,

jon

<joke>
Heh, I'm tempted to propose:
	/Documentation -> /docs
or
	/Documentation -> /Docs
</joke>

Ok, so let's keep tools/docs then. We need to decide about python
lib. On my series, I'm placing at tools/docs/lib, but I guess we
can change it later.

From my side, I would prefer to have a single directory for tools,
as we may place there things that aren't specific to docs.

For instance, I have my own class that I use for command execution,
using asyncio. The rationale is that it allows output messages in
real time without needing to wait for the entire process to end(*).

(*) I recently discovered a way to do that without needing asyncio,
    which makes the code a little bit simpler.

Either using asyncio or not, a class for such purpose is something
that multiple tools could use. So, a generic dir like tools/lib, 
lib/python, ... IMO makes sense.

With regards to the RFC, IMO we still may need to discuss how we'll end 
placing libraries under a LIBDIR. IMO, your RFC should also propose
a directory structure. I mean, we could have something like:

	LIBDIR     # either tools/docs/lib, tools/lib, lib/python or whatever
	|
	+---> common
	\---> docs
		|
	    	+---> kdoc
	    	\---> abi

We could instead do:
	- flatten "common" to LIBDIR; or:
	- flatten "docs" to LIBDIR; or:
	- flatten both but keeping kdoc, abi, ... directories inside
	  LIBDIR; or:
	- have a completely flatten directory with everything
	  under LIBDIR.

I proposed the former at a maintainers summit a few years ago ... the
response was less than fully positive.  I guess the fact that docs have
the longest and only capitalized top-level directory name shows their
relative importance :)

This is just flushing the output buffer?  Asyncio seems like a heavy
tool for that; I guess I'm missing something.

I agree with this, anyway.  "tools/python" might end up as the winning
suggestion.

I'm not sure we need the common/docs intermediate directory.

Meanwhile, I had a related, possibly unpopular idea...  Start with
.../tools/python/kernel and put a basic __init__.py file there;
everything else would go into that directory or before.  The imports
would then read something like:

  from kernel import abi_parser

That would make it clear which modules are ours and which come from
elsewhere.

I was planning to toss together another RFC with that scheme, again to
see what it would look like in practice.

Thoughts?

Yes, flushing output as they arrive while storing results from stdout and
stderr and handling  "stdin", eventually dynamically printing stdin when
debug is enabled. The problem sounds simple, and this is really easy to
implement in Perl. However, on Python, this ends to be a very complex
problem that one can only get all the caveats after implementing unit 
tests and then discovering, for instance, that, if stdin is bigger than 
32KB, Python read logic freezes forever (or until gather() timeout, and
the stdin was incomplete.

To fix it, one needs to implement a different stdin function that can't
wait anymore for the end of a read operation, but instead needs to pick
buffers in small chunks. Plus, the subprocess execution method requires
some unusual buffering parameters.

Not against something similar to it, but IMO "kernel" is a bad
name as it sounds something that runs in kernel stace or for Kernel
build. It could be, instead:

	from lib import abi_parser

Yet, I guess it may still need to add something at PATH, depending from
where current working dir the script was called (but tests required).

For instance Documentation/sphinx would need to pick lib from
"../../tools/python". So, I guess Sphinx extensions need first to
do:

	sys.path.insert(0, "../../tools/python")

and then:

	from lib import abi_parser         # or:
	from lib.abi import abi_parser     # or:
	import .abi_parser


Btw, nothing prevents moving extensions from Documentation/sphinx
into tools/sphinx_extensions. We just need to add the path insert
at conf.py.

Part of my purpose was to make it clear that the import was coming from
our own library - to distinguish it from all of the other imports that
these programs have.  "Kernel" seems good to me, but we could call it
"kernel_lib" or some such if we really want.  "lib" seems too generic.

> Yet, I guess it may still need to add something at PATH, depending from

That seems hard to avoid, yes.

Of course, we could require that all kernel tools run in a special
virtualenv :)

I feel less of a need to do that; it seems that the Sphinx-specific
stuff can stay where it is.  Though I guess I wouldn't scream too loud
if people really wanted to do that move.

Ok. let's stick with "Kernel" then.

No need. Yet, if you look at sphinx-build-wrapper, it has a "-V"
command line. If used, it will either pick a venv name or seek for
sphinx_latest and run from there. I wrote it mainly to help me
on my main devel machine, where I opted to have several different
venvs instead of installing via OS.

I was tempted of making the tool autodetect venv, if sphinx-build
is not found. I opted to not do it for now, but keeping it in mind
for a possible future change. There is also a code that detect if
Python is too old, running a newer version of it if found at the
system if required by the tool to run. 

Maybe we can place both logic into a library and let most tools
use it, adjusting the main function call to something like:

	MIN_PYTHON_VERSION = (3, x, y)

	def main(...):
	   ...

	if __name__ == "__main__":
	     run_on_version(MIN_PYTHON_VERSION, run, use_venv_if_available=True)

Ok. As on extensions we always have srctree set (sphinx-build-wrapper
warrants that), the PATH will always be relative to the kernel
directory, e.g.:

	srctree = os.path.abspath(os.environ["srctree"])
	sys.path.insert(0, os.path.join(srctree, "tools/python"))

	from Kernel import abi_parser

The only advantage of moving them to tools/python would be to remove
the need of "srctree" env, using instead os.path.dirname(__file__), 
e.g.:

	sys.path.insert(0, os.path.dirname(os.path.realpath(__file__)))
	from Kernel import abi_parser
	
but still at lease some extensions still need srctree anyway. So,
not really necessary.

So, let's not touch it then.

Thanks,
Mauro

This will conflict with my series getting converting it to Python.

I prefer if you don't merge this one.

Anytime. I'm very glad to see that the Python version have been work
nicely, and having you, Jon and others looking on its code. My feeling
is that it will be easier to maintain.

I would prefer tools/docs ;-)

The rationale is that it is common to have patches for Documentation
described with "docs:" prefix. Anyway, I don't mind that much.

Btw, one of my pending patch series is creating a new *.py script over
tools/docs (moving a script from Documentation/sphinx) ;-)

I prefer if you don't touch those two. I'm already handling them.

Basically, parallel-wrapper.sh will be decommissioned; parse-readers.pl
will become parse-headers.py (on my series, at tools/docs, but if you
opt to tools/doc, I'll update it.

lib/ contains code that's built into the kernel, I think lib/python
would be out of place.

IMO tools/python (or tools/lib/python, no strong opinion) is more
appropriate.

along with using either of tools/doc/ or tools/docs/.

Would tools/docs/lib be OK?
I wouldn't tie it up to a specific language,
but I don't have a strong opinion either way.

I think the question is, is the directory for libraries used by
documentation tools *or* for python libraries used by tools in general?

I would lean towards the latter, to not create another dilemma when a
library is used by both documentation and other tools.
