[gentoo-portage-dev] [PATCH] per package environment: generalize the mechanism to be profile specific

[Bertrand Simonnet]

[-- Attachment #1.1: Type: text/plain, Size: 1152 bytes --]

Hi guys,

I have been working on a patch to make package.env (and env/ files)
stackable with the profiles.
The main goal would be to have a mechanism to be able to define a
per-package, per-profile environment in a simple way.

We can currently do this with profile.bashrc but we have to add some logic
there to decide which package are relevant which already exist in ebuild.sh
and pym/*.

I attached my current patch which contain two main modifications:
- ebuild.sh walk the profile and source all scripts with path:
${profile_path}/env/${category}/${PN}
- config.py imports package.env from all profiles and then from
/etc/portage/package.env

Note:
* I gated the env/$CATEGORY/$PN scripts with a new feature: per-profile-env.
   I couldn't do this with package.env as the scripts are parsed before we
initialize self.features.
* I am not particularly attach to both package.env and env/$CATEGORY/$PN.
It might make more sense to have only env/$CATEGORY/$PN, especially
considering the problem with package.env.

Do you have any suggestions on this patch ?

Would you be willing to accept this patch once the few problems are sorted
out ?

Thanks!

Subject: [PATCH] Make package.env and env profile specific

Allows profiles to override environment variables throught package.env and env.
package.env becomes a per-profile configuration like package.use and
package.mask.

The environment bash file invoked by package.env must me placed in the same
profile.

It seems like duplication of work, to load the per-package env in
_grab_pkg_env on the python side, and to source it again on the bash
side. Why load the environments in both places? Note that the python
getconfig function only supports variable settings (no executable code),
which is very limited to what can be done when sourcing the files in bash.

1) If you want both the python-side env loading and the bash-side env
loading, I would make those into separate features, since sourcing the
files in bash supports full bash syntax while the python-side getconfig
function does not.

2) When adding new global functions in ebuild.sh, please unset them
inside bin/save-ebuild-env.sh, when internal functions are stripped from
the environment.

3) You might want to look into using the repository's
metadata/layout.conf profile-formats setting, as an alternative to using
FEATURES to control profile-related behavior.

I can't speak for everyone, but I'm pretty sure we can work something out.

Second patch containing only the ebuild.sh change.
Answers to suggestions inline.

The python part was mostly useful from a reuse point of view (write few
scripts
and enable them for some packages only. As the python mechanism is less
powerful
than I thought, I removed it.

Fixed: removed the python part completly

Done.

I replaced the FEATURES gate by a profile-formats option.
I added some logic to find layout.conf for a given profile path. (find the
first
parent dir named profiles then check ../metadata/layout.conf)
Is there a corner case that I missed?

Subject: [PATCH] Make env/ bash scripts profile specific

This generalize the /etc/portage/env mechanism to be stackable with profiles.
ebuild.sh will walk the profiles and sources scripts in env/ following the same
matching rules as for /etc/portage/env.

I all looks good to me, except that I don't like the way that
__profile_env_enabled parses the layout.conf for each directory, since
it's terribly inefficient. It would be much better to parse the
layout.conf data on the python side, and pass it to bash as an
environment variable. For example, the PORTAGE_ECLASS_LOCATIONS variable
is generated in python such that eval can be used to convert it to an
array. We can add a similar array variable called
PORTAGE_PROFILE_ATTRIBUTES, and each element of the array will
correspond to the profile path at the same index in the path_array variable.

I moved the profile attributes detection logic into the python side as
suggested (much cleaner).

The updated patch is attached.

Thanks,

This generalize the /etc/portage/env mechanism to be stackable with profiles.
ebuild.sh will walk the profiles and sources scripts in env/ following the same

Thanks, that's better. I've got a couple more issues though:

1) Like global functions, global variables should also be unset in
__save_ebuild_env. So, we should unset PORTAGE_PROFILE_ATTRIBUTES there.

2) Instead of having _get_profile_attributes read the layout.conf files
directly, it would be nicer if we could integrated it with the
LocationsManager layout.conf parsing. For example, see the
intersecting_repos code inside the _addProfile method.

Great, thanks for your review.

I have just realized that we forgot to document the new layout.conf

I'll add documentation for profile-env.
Do you prefer having it in the same patch or in a separate one ?

While whitespace fixes are generally a good idea, please don't mix them
with feature patches. It makes reviewing harder, for a start.

I think you should use 'has' helper function here. The pattern match
would also succeed with 'subprofile-envofoobar' and we don't want
that :).

> +				__source_env_files "${profile_path}/env"

Could you split the patch into smaller, logical changes? If that's too
much of a hassle, then nevermind but I would prefer to have it like:

1) refactor the code to use __source_env_files and so on without
having anything directly related to new features yet,

2) add support for querying profile attributes,

3) add new profile-env support.

This way, we could distinguish better between what you refactored
and what you added.

This looks like a very confusing usage for a function. It would be
really preferable to use syntax similar to standard utilities, e.g.:

  __try_source --no-qa "${PORTAGE_BASHRC}"

Now I understand what the patch does. I don't think we want to actually
expand use of this verbose-style env files. I'd rather go for
package.env only since it is more in line with other package.* files.

I'm pretty sure you could get this smaller if you put the long
conditional in a variable and use it twice just to control 'set -x' /
'set +x'. In pseudocode:

  [[ ${debug_on} ]] && set -x
  if [[ ... ]]; then
    source
  else
    qa_source
  fi
  [[ ${debug_on} ]] && set +x

I'm not sure if dedicated profile format is the best way to go. If I
understand your patch correctly, this means that 'profile-env' has only
features of PMS profile but not of 'portage-*' formats. This could mean
that some people would have to choose between features of one or
the other. Since both are compatible, i suggest 'portage-3' instead.

The profile-formats field is designed to allow mixing of formats. So,
it's legal to mix profile-env with any of the other formats.

Michal, not opposed to splitting the patch into three parts.

I'd rather use the env/ mechanism instead of the package.env one as it is
more flexible.
It also feels better as ebuild.sh will walk the profiles to source the
bashrc script so a bashrc from a
"low priority" profile may override a package.env definition from a high
priority profile.

I'll remove the with spaces and the Change-Id (gerrit specific tag I
believe)

Please find the patch split into three smaller patch:
* refactoring: contains the Michal's suggestions. I also removed the
whitespace changes.
* profile attributes export: same as in the previous patch
* profile-env patch: uses "has" to check if profile-env is set. I also
included the documentation in portage.5.

The Change-Id git hook was disabled for this round of patches ;)

It depends on what you aim to do. As portage(5) points out, both have
their advantages:

- package.env is parsed early, and so allows you override more
  variables, like FEATURES,

- env/ is used as bashrc extension.

The other difference is that package.env supports any atom syntax that
the particular EAPI supports, while env/ has hardcoded list of
possibilities.

For my purpose, I think bash scripting would be more useful. I thought
about package.env
in the beginning (see first few messages on this thread) as it would help
us reuse code but
variable setting only will limit what we can do.

If you want package.env, we can implement it too and have both mechanisms
available.

Thanks,
Bertrand

Zac, Michal,

Would you be willing to merge this ?
If env/ instead of package.env is a deal breaker, I can change that.
A bashrc like mechanism is more practical for us but package.env will do
the trick too
and we really want to have this in mainline portage.

Thanks,
Bertrand

In order to solve Michał's concern about the "hardcoded list of atoms",
we might choose this slightly different approach:

In python, parse package.env atom/file associations from the profile,
and pass the associated file names to bash as array, so that those files
can be sourced by bash.

Thoughts?

be able to adjust FEATURES. However, I'm not so sure that per-package

Did you mean env/ files ? Having a different behaviour for
/etc/portage/package.env and $profile/package.env would be confusing.

Parsing env/ atom/files association in python would be a good idea. We
should get the benefits of both I believe.
The list of files to be sourced by bash could contain all the files
relevant to the package in one profile then profile.bashrc, for each
profile so that
we don't even need to walk all the profiles in ebuild.sh.

Yes.

We could call package.bashenv (or something like that), in order to make
the difference from package.env clear.

I don't know why he hasn't responded yet. I've just pinged him in the
#gentoo-portage irc channel.

Anyway, I think the proposed package.bashenv approach is great. I think
we should also support this in /etc/portage as a replacement for the
existing hardcoded atoms method.

I have mixed feeling about having yet another package.* file but
the idea sounds good. However, I'd prefer naming it
'package.bashrc' (since it pretty much points to bashrcs, doesn't it?)
and using a new subdirectory like 'bashrc/' instead of re-using 'env/'
to avoid confusion.

That sounds pretty reasonable to me. I really like the idea of using a
new directory name. When we added package.env support, I wasn't very
comfortable with re-using the /etc/portage/env directory which was
already being used for bashrc, but we did it anyway because others
thought it would be fine.

[gentoo-portage-dev] [PATCH] per package environment: generalize the mechanism to be profile specific

[Bertrand SIMONNET]

Hi all,

Please find the patches implementing package.bashrc, the bashrc mechanism
parsing the atom names in python.

I split the change into three smaller changes:
* Refactoring ebuild.sh  (same as the first refactoring patch)
* Include profile-formats in profile_complex
* package.bashrc change

I also included the documentation for package.bashrc in the latest patch.
Let me know what you think :)

Thanks,
Bertrand

Profiles can define per-package bashrc files to be sourced before emerging.
Each line in package.bashrc must be an atom name then a list of space-delimited
bashrc files (stored in $profile/bashrc/).

We will be having a team meeting soon to decide recent patches, etc..

Although I think for the 2.2.14 final release we will not include this,
just a few bug fixes.  After 2.2.14 final is released we will likely
merge it so it will be in 9999 for awhile and then the 2.2.15 release.

It sounds good.
If you think this will not change dramatically between now and the merge,
I'll cherry-pick this on our portage version while waiting for the 2.2.15.

Let me know if something goes bad before the merge.

Thanks for the review :)

Should we go ahead and merge this now that 2.2.14 is released?

Thanks, I've pushed them to git now:

https://github.com/gentoo/portage/commit/60ee4deefb701d532fdd279caa989e7a6f4b8400
https://github.com/gentoo/portage/commit/1d351a59a57e018e9c79a371f0cae21505c2249c
https://github.com/gentoo/portage/commit/803dafc462027d6015721f40513abb5f57dc1178

In the last patch, I made 2 trivial changes:

1) Replace self.configdict["BASHRC_FILES"] with self._pbashrc, since configdict is used
for other unrelated things. Also make it an immutable tuple instead of a list.
2) Test if profile.bashrc exists before adding it to the list, which typically shortens
the list drastically because most profile directories don't have a profile.bashrc.

[gentoo-portage-dev] [PATCH] per package environment: generalize the mechanism to be profile specific

[Bertrand SIMONNET]

Hi all,

Here is the implementation of package.bashrc, split into three patches:
* refactoring of ebuild.sh (same as the refactor earlier in this thread)
* adding profile-formats to profile_complex (so that it can be used in
  ebuild/config.py)
* package.bashrc change (including documentation)

Let me know what you think :)

Thanks,
Bertrand

[gentoo-portage-dev] [PATCH 1/3] Refactor bashrc scripts sourcing

[Bertrand SIMONNET]

Creates two new helper functions __try_source and __source_env_files to simplify
__source_all_bashrcs.

In order to ensure that INSTALL_MASK set via bashrc will always works as
intended, you'll have to modify the INSTALL_MASK logic inside the
dblink.treewalk method:

if self.settings.get("INSTALL_MASK") or \
	"nodoc" in self.settings.features or \
	"noinfo" in self.settings.features or \
	"noman" in self.settings.features:
	# Apply INSTALL_MASK before collision-protect, since it may
	# be useful to avoid collisions in some scenarios.
	phase = MiscFunctionsProcess(background=False,
		commands=["preinst_mask"], phase="preinst",
		scheduler=self._scheduler, settings=self.settings)
	phase.start()
	phase.wait()

We could simply run the preinst_mask function unconditionally here,
since we can't tell whether or not the bashrc contains an INSTALL_MASK
setting.
