[OE-core][PATCH] rpm: disable the RPM 6 script interpreter dependency generator

[OE-core][PATCH] rpm: disable the RPM 6 script interpreter dependency generator

[Roshan Sivakumar]

RPM 4 generated dependencies with the external __find_requires /
__find_provides generator, which OE disabled entirely via
_use_internal_dependency_generator 0. RPM 6 removed that mechanism; for
v6-format packages only the internal fileattr generators run.

rpm's script.attr generator therefore runs for the first time in OE
builds. For every packaged executable whose first line is a #! shebang
it emits an interpreter dependency. kernel-devsrc ships
scripts/mksysmap (#!/bin/sed -f) as an executable, so its package gains:

  Requires: /bin/sed

OE manages build and runtime dependencies explicitly through
DEPENDS / RDEPENDS and does not want these. They break real use cases:

- The interpreter path is taken verbatim from the shebang. A #!/bin/sed
  script requires /bin/sed, but under usrmerge the only provider
  (busybox) offers /usr/bin/sed. The literal paths never match and the
  package becomes uninstallable.
- In the SDK the sole interpreter providers (busybox, coreutils, bash,
  perl) are deliberately banned by target-sdk-provides-dummy, so these
  auto-generated requires make -dev/-src packages uninstallable during
  do_populate_sdk ("nothing provides /bin/sed needed by kernel-devsrc").
- The requires are non-reproducible: they are only emitted when the
  interpreter is scanned from the shebang during packaging, so the same
  recipe can produce different packages between the reproducible A and
  B builds.

This is the same class of regression already handled for the pkgconfig
generator; see "rpm: disable the RPM 6 pkgconfig dependency generator".

Suppressing the generator from the rpmbuild command line
(__requires_exclude / __script_requires set to %{nil}) is not reliable:
rpm reloads the fileattr macros during dependency generation and
clobbers the --define. Remove script.attr and its helper script.req
from rpm's install lists via a source patch. This changes
do_unpack/do_patch, so the whole rpm recipe and everything downstream
re-hash and no stale rpm-native is reused.

I am not sure about the explicitly part. AFAIK, installed scripts with a 
#!/bin/bash shebang leads to an automatic dependency on bash. Whether it 
is RPM and/or bitbake doing that, I don't know.

Re: [PATCH] rpm: disable the RPM 6 script interpreter dependency generator

[Roshan Sivakumar]

[-- Attachment #1: Type: text/plain, Size: 407 bytes --]

I believe this dependency belongs here: openembedded-core/meta/recipes-kernel/linux/kernel-devsrc.bb at master · openembedded/openembedded-core ( https://github.com/openembedded/openembedded-core/blob/master/meta/recipes-kernel/linux/kernel-devsrc.bb#L460 )

RDEPENDS:${PN} += "sed" in the above recipe is the right way to do it?

There should probably be a separate patch to satisfy that dependency.

Hi @Peter<mailto:peter.kjellerstedt@axis.com>,

Can we merge this fix and handle the dependencies using RDEPENDS in the individual recipes that need them like mentioned above?

I believe this dependency belongs here: openembedded-core/meta/recipes-kernel/linux/kernel-devsrc.bb at master · openembedded/openembedded-core<https://github.com/openembedded/openembedded-core/blob/master/meta/recipes-kernel/linux/kernel-devsrc.bb#L460>

RDEPENDS:${PN} += "sed" in the above recipe is the right way to do it?

There should probably be a separate patch to satisfy that dependency.



Thanks,

Roshan.

I am not sure about the explicitly part. AFAIK, installed scripts with a
#!/bin/bash shebang leads to an automatic dependency on bash. Whether it
is RPM and/or bitbake doing that, I don't know.

RE: [OE-core][PATCH] rpm: disable the RPM 6 script interpreter dependency generator

[Peter Kjellerstedt]

[-- Attachment #1: Type: text/plain, Size: 11576 bytes --]

Well, I just feel that we are removing an existing feature if we do. It may be that it is only present when using DNF and RPM to generate the images (which we do), as I do not know whether the other packaging formats support dependencies on files. On the other hand, these kind of dependencies are often missed when adding them manually so if we are removing them from DNF/RPM, I think it would be more appropriate if bitbake detected them automatically, just like it automatically detects runtime dependencies for dynamic libraries.

I don't understand. What was enabled in rpm 4 and what was not? What ran
and what didn't? The above seems to say that rpm 4 used external generator,
which was disabled by oe, but then the disabling statement refers to
internal generator.

But if the script in a target package refers to /bin/sed, and the target
root filesystem is not providing that, then the problem is not with the
dependency checker, it's with the script and/or filesystem layout.
Disabling the check does not address that problem, it just sweeps it under
the carpet. Am I missing something? How does this work on Fedora for
example, which also uses usrmerge?

This probably needs steps to reproduce, so we can better understand the
issue.

I also don't understand this. How does the non-reproducibility happen
exactly? Why would it produce different requires?

There was also a concern during patch review that the checks that the
generator does are useful to catch missing runtime dependencies in recipes,
and disabling this would regress the packaging quality. Something like this
checker should be made generic (e.g. run in do_package, regardless of
specific packaging backend). How does this check work exactly, and where is
it implemented? Do we have an equivalent in do_package (I vaguely remember
that we do)? If there's an equivalent, then why it doesn't complain but the
rpm-specific check does?

This needs further investigation.
