cran2deb: put base_pkgs into the cache. generate cache so that R is happy. use separate base.tgz for cran2deb.
base_pkgs is the list of all packages that are provided in the basic
install of R. It is found by listing all installed packages in the
pbuilder environment.
Previously the cache of availabile packages lived in sysdata.rda.
Unfortunately it appears that R does not like it when sysdata.rda is
updated after package installation (I think this is something to do with
lazy loading, but disabling this did not seem to help). Instead the
cache is maintained separated in the data/ package directory.
pbuilder now uses base-cran2deb.tgz for the cran2deb pbuilder
environment -- this should help keep cran2deb from interfering from
other uses of pbuilder.
cran2deb: correct cran2deb dependencies. make cran2deb a meta-executable.
'cran2deb' is a script that determines the root of the cran2deb R
package installation and then invokes some other executable with this
root as the first argument. e.g.,
$ cran2deb update
$ cran2deb build zoo
The README file now includes details of what must be done to use
cran2deb.
also filter out SystemRequirement fails; this shows whether there are
still some C header and other failures attributable to things other than
declared SystemRequirements (short answer: there are, annoyingly).
cran2deb: extra dependencies on command line; fix nasty bug in cross-repo dependencies.
accept with a common typo of version in License:.
bail out on SystemRequirements
correct a nasty bug: dependencies[r,]$name displayed like a string in R,
but was actually treated as a number; hence some cross-repo dependencies
did not work correctly since the wrong available[] entry was being used.
allow some extra dependencies to be specified on the command line.
cran2deb: cache availabile packages. support cross-repo dependencies[1]. basic understanding of bundles (no building yet).
If an R package name is needed, and cannot be found in the available
packages, then try to resolve it into a bundle. If this works, then
substitute the name of the bundle for the package name and procede. This
is enough to get dependency resolution working and R source packages
downloaded, but still to do is the generation of debian/ for bundles.
[1] Appears to be some problems during building of bioc packages -- even
though the package is called r-bioc-XXX, a directory r-cran-XXX is
expected by some part. Suspect need to change generation of
debian/rules.
cran2deb: satisfy immediate R dependencies iff the requisite package has already been build.
Works by running apt-get update before each build, pulling in the
declared R dependencies from a local repository.
Still to do is actually read off a topological order and deal with
transitivity. Otherwise, this appears to work fine where the only
dependencies are those in Depends or Imports of the R DESCRIPTION.
Also included is to use Imports as well as Depends for generating R
dependencies... this was necessary for, for example, stashR --- not
quite sure if this is technically correct, but it allows this package to
work.
Constructs an archive that pbuilder can apt-get dependencies from when
necessary. This requires an http server to serve var/archive (can be a
symlink).
cran2deb: rebuild the source tarball each time removing file exec bit.
The subdirectory of an R package is 'pkgname'. Debian typically has
'pkgname-upstreamversion'. Hence the tarball is rebuilt after renaming
the 'pkgname' directory appropriately.
Whilst this is all going on, every file in the R package has its
executable bit removed. There would appear to be little correct need
for it at the moment (this will change when #! is handled better) and
this gets rid of some inappropriately executable files.
cran2deb: catch a few more licenses found 'in the wild'.
If the license does not look like a properly formatted one, strip away
anything harmless (space, punctuation, numbers, etc) and see if it
can be made to match a known-good license exactly.
cran2deb: use iconv(1) to convert debian/{control,changelog,copyright} to utf8
lintian(1) likes these files to be utf8. R does not specify a character
set, so this code just hopes that iconv(1) will do the right thing. In
the only case where it matters so far (lspls) this allows the package to
build and pass lintian(1).
cranpkgs & build_some: build a random subset of all available packages.
current result:
100 packages tried
23 failed -- all due to license problems: not considered
(MIT,BSD) or malformed field (e.g., GPL 2.0 or later)
'some' (uncounted) have significant lintian warnings (mostly
seems to be incorrectly +x files)
77 .deb files produced
License handling code now deals with version numbers and also the more
common malformed license fields found in the wild. License version
information is discarded completely at the moment (though retained in
debian/copyright).
debian/copyright also includes a copyright notice formed from the Author
field of DESCRIPTION.
Debian package names must be lower case; the Debian source package
of an R package is the lowercase form of the R package name, whilst the
binary package is r-<lower case repo>-<lower case R name>.
