Before this commit, package folders were copied into the chroot one by
one in order to run apkbuild-lint on them. This logic is replaced by
mounting pmaports.git into the chroot and using a single apkbuild-lint
invocation to lint the supplied packages.
Both of these changes result in a performance improvement, especially
when linting multiple packages at once.
Before this change:
$ time ./pmbootstrap.py -q lint $(cd ../pmaports/cross; echo *) \
> /dev/null
real 0m5,261s
user 0m7,046s
sys 0m1,842s
Using the pmaports.git mount but calling apkbuild-lint in a loop:
$ time ./pmbootstrap.py -q lint $(cd ../pmaports/cross; echo *) \
> /dev/null
real 0m4,089s
user 0m6,418s
sys 0m1,219s
After this change:
$ time ./pmbootstrap.py -q lint $(cd ../pmaports/cross; echo *) \
> /dev/null
real 0m3,518s
user 0m5,968s
sys 0m0,959s
Additionally, running apkbuild-lint from the pmaports.git mount point
has the benefit that every printed violation contains a nice source
identifier à la "./cross/grub-x86/APKBUILD". This makes it possible to
differentiate between different packages even though only a single
apkbuild-lint invocation is used.
