v.0.9.0 testing too many depenencis

[ccpster]

Version: v0.9.0

grpm -V
grpm version 0.9.0
Commit: 7dbb133
Built: 2026-01-19T13:08:54Z

This version produced much much better result compare to previous version, It is closer to my experience on emerge command.

However the grpm emerge -root=/roofs -pretend gcc-... created way too many dependencies than I anticipate, I suspect there is something wrong.
And I suspect the grpm resolve did same, but I cannot easly comfirm because the resolve out lack of information.

I would suggest if there is no mistake in term of dependecy resultion you may want to add feature that can show USE flags origin, i.e. if it came from profile, or came from make.conf like the way portage do. but this is not high prority thing

The downloading distfile still fail. I suggest use a different issue number to track this download issue. so it is easier for reporting.

Note: the output list have to be truncated to fit into post box.

Thanks for the detailed testing! You're absolutely right — this was a critical bug.

Fixed in v0.9.1 (just released): https://github.com/grpmsoft/grpm/releases/tag/v0.9.1

Root causes:

• USE-conditional deps were included regardless of USE flag state
• All deps traversed even if already installed
• BDEPEND included for packages already built

Now grpm resolve behaves like Portage — only shows packages that actually need to be installed.

New flags for control:

• --emptytree — show full tree (your current behavior)
• --deep — traverse installed package deps
• --with-bdeps — include BDEPEND for installed

Please test v0.9.1 and let me know if the numbers look correct now!

https://github.com/grpmsoft/grpm/releases/tag/v0.9.3 - try this version please.

[kolkov]

v0.9.4 is out with major interpreter hardening: https://github.com/grpmsoft/grpm/releases/tag/v0.9.4

Fixes relevant to your report:

• Version resolution in SRC_URI — ver_cut/ver_rs now default to $PV when version argument is omitted (was causing gcc-config 2.12.1 vs 2.12.2 mismatch)
• Signature file filtering — .sig/.asc files no longer downloaded when verify-sig USE flag is disabled
• .tar.lz unpack support — packages like timezone-data now unpack correctly
• Metadata extraction hardened — stripFunctionBodies, BASH_VERSINFO emulation, eclass stdout isolation
• 33 new tests, 214+ helper functions, ~80% PMS compliance

Please test with:

grpm emerge -root=/rootfs -onlydeps -pretend "=sys-devel/gcc-13.4.1_p20250807"

The gcc-config version mismatch should be resolved now. Let us know how it goes!
