[Buildroot] [PATCH v2 0/6] Bugfixes for pkg-stats

[Fiona Klute via buildroot]

Hi everyone,

this series is a collection of small bug fixes for
support/scripts/pkg-stats, fixing bugs I bumped into checking a fairly
simple build with it:

* Incorrect upstream URLs (most notably for the Linux kernel, and I
  had a wrong one for a package in an external tree due to an Emacs
  backup file), patch 1 + 3

* Entries for *missing* upstream URL would still be links with
  href="None", patch 2

* The "infrastructure" column would list "host-* (target)" when a
  package that supports a host build is actually built only for the
  target, patch 4

Patches 5 and 6 are small fixes for the script itself (don't
unnecessarily load whole package files, allow importing the script as
a module).

I see a bunch more things that should be fixed (notably virtual
packages reporting missing license/hash info when there simply is
none, and the package parsing process itself), this is what I had time
for.

One question for possible future improvements: Is the JSON output
format documented/defined anywhere, or simply "what the script
produces, subject to change"?

Best regards,
Fiona

[Buildroot] [PATCH v2 1/6] support/scripts/pkg-stats: search only Config.in{, .host} for URL

[Fiona Klute via buildroot]

The previous Config.* glob also caught linux/Config.ext.in and
package/php/Config.ext, as well as some backup files created by
editors (e.g. Config.in~ after editing a Config.in file in Emacs),
leading to wrong results depending on directory listing order.

Also use "with" to automatically close the file when the block is
left, even on error.

This cannot solve the problem we have no structured URL information
and don't look at which option the URL is listed under, but at least
it's less wrong.

Changes v1 -> v2:
* Try fixed names instead of globbing all directory entries

  Applied to master, thanks.

  Does either of these actually cause problems?

  What is still incorrect is that it doesn't report when Config.in doesn't have 
an upstream URL while Config.in.host doesn't.

  We could modernise things by switching to pathlib and using .exists() a priori 
(and never mind the exception in case of TOCTOU or unreadable file).

  But that's further improvement :-)

Rarely. If there are multiple URLs in one config file, we simply pick 
the first one, so now for linux/Config.in you always get the kernel.org 
URL added in this series, even if you selected the CIP kernel which has 
its own URL in its help text. There probably aren't many packages where 
that's an issue.

Mostly it just feels awkward to probe the help text instead of having an 
explicit definition.

True. Though in that case we'd also have to differentiate between that 
and "there is no Config.in" for host-only packages. So far pkg-stats 
treats host and target packages as one and only reports infra separately.

I agree. I kept this series to simple and hopefully uncontroversial 
fixes, didn't want to get into full refactoring right away. ;-)

[Buildroot] [PATCH v2 2/6] support/scripts/pkg-stats: format upstream URL info consistently in HTML

[Fiona Klute via buildroot]

Use only one of the classes for "error" or "warning" status so they
look different, and format the error/warning text for both. Do not
make the text a link if the URL is None.

  It looks like this could have been used below instead of repeating 
pkg.status['url'][1]. But I'm too lazy to test so I left it unchanged.

[Buildroot] [PATCH v2 3/6] linux/Config.in: add kernel.org URL as BR2_LINUX_KERNEL_LATEST_VERSION help

[Fiona Klute via buildroot]

This makes it the first URL in the file, so it shows up correctly in
pkg-stats output.

  I don't see any reason to put it here rather than in the top-level option 
BR2_LINUX_KERNEL. So I did change that and put it there (and stripped most of 
the commit message).

[Buildroot] [PATCH v2 4/6] support/scripts/pkg-stats: fix host/target infra filter

[Fiona Klute via buildroot]

The filter is supposed to exclude host/target infra from output if the
respective package is not built with the current
configuration.

However, excluding host packages did not work correctly: If keep_host
is False because the host package is not built, the next branch was
checked and included the host infra in output with "target" type if
the target package is built. For a package that support host and
target build, but gets built only for the target, this leads to output
like (Meson example):

meson (target)
host-meson (target)

Skip host infra in the target branch instead. Also include
Package.infra in Package.__str__() result, which was needed for
debugging this bug.

[Buildroot] [PATCH v2 5/6] support/scripts/pkg-stats: don't buffer whole file searching for infra

[Fiona Klute via buildroot]

The file handle can be iterated over directly and each line is used
exactly once, so the only effect of reading all lines into a list
first was higher memory use and complexity.

[Buildroot] [PATCH v2 6/6] support/scripts/pkg-stats: run main function only if called as script

[Fiona Klute via buildroot]

The __name__ == '__main__' guard allows importing pkg-stats as a
module using importlib, circumventing the normal module filename
requirements. This in turn makes it possible to test/debug individual
functions.

Re: [Buildroot] [PATCH v2 0/6] Bugfixes for pkg-stats

[Arnout Vandecappelle via buildroot]

  Hi Fiona,

  I'm making an attempt to get this series merged :-)

  As a preliminary remark though: pkg-stats really should evolve to using 
show-info output instead of parsing files itself - that would solve the things 
like the incorrect patches and hash files. There's one big blocker for that 
though - pkg-stats supposed to be able to work without a .config, and show-info 
currently doesn't.

  Ideally pkg-stats would have documentation, including of its JSON output. And 
tests as well. We can only dream...

I see you were successful, thank you! :-)

Interesting! Is that documented somewhere, e.g. in notes from a 
developer meetup or something?

I'd like a JSON schema with descriptions, that would also help with 
adding tests. ;-)

I was actually wondering if it'd be possible to apply for a grant for 
Buildroot work, e.g. with NLnet NGI Zero [1]. It would be easiser to 
tackle larger changes that way: There's this, maybe kind of related SBOM 
stuff I was involved with before for a client (left unfinished/pending 
because the project ended), and I have some ideas for an overhaul of the 
test system.

If that's an option (as in, maintainers approve of the idea) I'd like to 
collect requirements/ideas/issues as base for a possible grant application.

Best regards,
Fiona

  No, it's more a vibe than a real decision. When Thomas introduced show-info 
for the -c option of pkg-stats in 7a607dab3, the feedback was "that's great, we 
should always do that" but that turned out to be impossible so it got merged as is.

  I wouldn't say no to that! We actually also have sponsors that could 
contribute more. I guess it would have to be routed through the Buildroot 
Association then.

Totally agree: it's a great idea!
