Comment 3 John Bowler 2024-02-03 17:12:06 UTC
The actual error is:

>pngvalid: read: truecolour 16 bit: transform: +rgb_to_gray^0.45455: red/gray output value error: rgba(5612,492,8364,65535): 3648 expected: 3657 (3648.500..3665.111)
pngvalid: 1 errors, 0 warnings

I.e. a value in the libpng implementation is outside the range permitted by 'limit' checks in pngvalid (which uses floating point to calculate a more accurate answer):

>3648 expected: 3657 (3648.500..3665.111)

Not a particularly bad error; it's too low by .25% but human vision can at best distinguish 1% differences in luminosity.

Looking at the change log from v1.6.17 to current (v1.6.42) immediately after 1.6.17 was released this commit (github.com:pnggroup/libpng) a21a5b22c10b900d44d40fe30a203302b2a67f8b "fixed" rgb_to_gray checks.  At that point pngvalid limit checking was still being heavily worked on.  I suspect that the error may not show now.

However commit 2225ca0a540c7ac5da1e700c284dec8d64f2108c also increases the allowed range of some checks and disables certain checks in release and RC builds.

So I expect this issue to have "disappeared".

It also seems the media-libs/libpng is no longer executing 'make check'; I'm not sure about this but yesterday I built media-libs/libpng several times with patches that did, in fact, cause 'make check' to fail and they installed fine.

A quick test is to use ebuild to compile on the relevant architecture and run 'make check' by hand.
