patch to fix bsd.port.mk

Problem: Using github groups 
(see "Fetching Multiple Files from GitHub" of Porter's Handbook)
along with non-empty WRKSRC_SUBDIR
leads to garbage in WRKSRC variable.

Consider hypotetical port from Example 5.15 of Porter's Handbook,
with addition of non-empty WRKSRC_SUBDIR.

PORTNAME=       foo
CATEGORIES=     security

USE_GITHUB=     yes
GH_ACCOUNT=     bar:icons,contrib
GH_PROJECT=     foo-icons:icons foo-contrib:contrib
GH_TAGNAME=     1.0:icons fa579bc:contrib

WRKSRC_SUBDIR=  core/server/

.include <bsd.port.mk>

Experiment 1. With original file Mk/bsd.port.mk.orig:
$ cd /usr/ports/security/foo
$ make -V WRKSRC
/usr/ports/security/foo/work/foo-icons:icons foo-contrib:contrib-1.0.2/core/server/

which definitely puts garbage into WRKSRC variable.

Experiment 2. With patched file Mk/bsd.port.mk:
$ cd /usr/ports/security/foo
$ make -V WRKSRC

which works as intended.

The reason of failure with original file Mk/bsd.port.mk.orig is in its lines 1725-1727:

.if defined(WRKSRC_SUBDIR)
WRKSRC:=                ${WRKSRC}/${WRKSRC_SUBDIR}

which come earlier, than line 2245:
.include "${PORTSDIR}/Mk/bsd.sites.mk"

Hence value of GH_PROJECT in line 1705:
contains a list of data: 
GH_PROJECT== foo-icons:icons foo-contrib:contrib
instead of needed value:

Proposed change to line 1705, that is substitute
solves the problem, because GH_PROJECT_DEFAULT==foo 
during all stages of "make" operation.
Comment 1 Sergei Vyshenski 2020-05-04 21:35:13 UTC
This patch also works fine for ports with github origin, which do not have submodules (groups).
Comment 2 Sergei Vyshenski 2020-05-04 22:33:22 UTC
See PR#245375 for a real example of existing port with conflict between github groups and non-empty WRKSRC_SUBDIR.
