[gentoo-guru] [RFC PATCH 2/3] eclass/R-packages: substitute _ with . in SRC_URI and HOMEPAGE

[Robert Greener]

This is done throughout other parts of the eclass, it would mean that
the SRC_URI and HOMEPAGE wouldn't need to be overrided in the ebuilds.
For example, in the case of data.table.

[gentoo-guru] [RFC PATCH 1/3] eclass/R-packages: Use src/contrib or src/contrib/Archive from main CRAN

[Robert Greener]

The current SRC_URI searches all the CRAN mirrors for
/src/contrib/${PN}_${PV}.tar.gz. This is problematic. Once a package is updated
on CRAN, the package is removed from this path and moved to
/src/contrib/Archive/${PN}/${PN}_${PV}.tar.gz. The effect of this is
that once a package goes out-of-date on CRAN, the ebuild will no longer
build. This significantly increases the maintenance burden of dev-R/*
packages, as it requires that they be up-to-date at all times.

The proposal here, is to use just the main CRAN, so that every mirror
doesn't have to be searched, to search the main repo, and then the
archive. (also, some CRAN mirrors seem misconfigured and return a html
document if the package is not found at
/src/contrib/${PN}_${PV}.tar.gz). This means that if the package is
out-of-date it will still build.

Add a variable CRAN_PV which defaults to PV, but can be overridden in
the ebuild. This is useful for the case where the version number is
something like "1.2-24" as it often is with R packages, this would mean
that a variable like "CRAN_PV=$(ver_rs 2 -)" could be defined in the
ebuild, which is used in the SRC_URI of the eclass. If CRAN_PV isn't

Multiple SRC_URI doesn't work as fallback. You need a custom src_fetch
function instead.

I'd introduce a new variable CRAN_PN instead.

[gentoo-guru] [RFC PATCH v2 0/4] eclass/R-packages: improvements

[Robert Greener]

Hello,

Here is v2 of the improvements to eclass/R-packages. Thank you
Alessandro and Anna for your comments.

This time, I use the microsoft cran snapshots (MRAN), to download the
package if CRAN_UPD_DATE is set. If this is not set, then CRAN is used
as normal.

The intention would be to update all packages in dev-R to use
CRAN_UPD_DATE and then remove the if guard around this.

What do you all think?

This can be overridden in the ebuilds, but if its not defined it is the
package name with _ substituted with periods. This maintains the
existing behaviour.

[gentoo-guru] [RFC PATCH v2 3/4] eclass/R-packages: Add CRAN_UPD_DATE and use MRAN.

[Robert Greener]

The current SRC_URI searches all the CRAN mirrors for
/src/contrib/${PN}_${PV}.tar.gz. This is problematic. Once a package is updated
on CRAN, the package is removed from this path and moved to
/src/contrib/Archive/${PN}/${PN}_${PV}.tar.gz. The effect of this is
that once a package goes out-of-date on CRAN, the ebuild will no longer
build. This significantly increases the maintenance burden of dev-R/*
packages, as it requires that they be up-to-date at all times.

The proposal here, is to use the snapshots of CRAN provided by
Microsoft. This requires an additional variable set in the ebuilds, the
update date. This can just be set to the date that the ebuild is
updated. By setting this, out of date packages will continue to build.

Yes. It means that it would be a live ebuild, and we couldn't benefit
from the manifest, so it's a bit of a pain.

Check out v2 of the patch
(message id: 20220706122142.125975-1-me@r0bert.dev)
and see what you think.

In the updated patch, I define a variable CRAN_UPD_DATE that uses
snapshots of cran so the link never dies.

I prefer the name CRAN_SNAPSHOT_DATE but I will not force to use it if you
don't like it.
