[Bioc-devel] Should GenomicFeatures really depend pn RMySQL ? Is it time to migrate to RMariaDB ?

GenomicFeatures_1.31.3 imports RMySQL.

I'm having great trouble installing RMySQL from source on a recent MacOS
(10.13.3) with homebrew.

The package's homepage says "The 'RMySQL' package contains an old
implementation based on legacy code from S-PLUS which being phased out. A
modern 'MySQL' client based on 'Rcpp' is available from the 'RMariaDB'
package" https://cran.r-project.org/web/packages/RMySQL/index.html

So is it time to heed that advice and migrate GenomicFeatures to
RMariaDB ?

Out of curiosity, is MariaDB easier to install on your system? Its system
dependencies are described at https://CRAN.R-project.org/package=RMariaDB

I have no problems installing RMariaDB on MacOS (10.13.3) on an R-devel
from source, after installing mariadb-connector-c with homebrew.

OTOH, I have not figured out a way to install RMySQL neither on my R-devel
from source (various complaints about missing .h files) nor on a binary R
3.4.2 with the binary package download (complaints about missing system
libraries / wrong versions).

Thanks and kind regards

FWIW MySQL is a relatively recent addition as a dependency to

GenomicFeatures; it enables `makeTxDbFromEnsembl()`, which is probably a
much more stable solution than `makeTxDbFromBiomart()`. On the other had
Johannes does an excellent job on the ensembldb packages, so perhaps this
code could really be conditional with the RMySQL dependency moved to
