Thanks very much for that post, Fernando. I'm not bothered at all :-)
Actually, there are 3 alternatives for downloading the files. I summarize them
so that it is recorded on the list:
- maintain them on anduin, as we do now, and provide the anduin link to the
book.
- using wget as described by Fernando. This adds wget as a dep. I guess most
people would not care, since wget is a basic package, which I guess is
installed by almost everybody.
- using mercurial to get jdk8u45-b14, and downloading all the other needed
files with "sh get_source.sh". This requires to install mercurial first.
2 notes:
- maintaining some files on anduin has to be done anyway, because we provide
binaries. Also, the jtreg tarball is rebuilt every other day or so, and is not
guaranteed to work the same as when the BLFS page was written, so it is better
to have it on anduin too. Actually, jtreg can be built from sources, but it
needs a half dozen specific deps, which I think is not worth it.
- the 2nd and 3rd method brake the (implicit and not always respected) rule
that all the needed files should be downloaded before starting to use the
instructions in the book.
I am not sure what is the best alternative. I would say the same as Fernando
(2nd alternative), but see notes above...
Thoughts?
