Subject: Make Packages & Sources generation optional, during Generate call
X-Git-Tag: 1.0.8~19
X-Git-Url: http://git.hcoop.net/ntk/apt.git/commitdiff_plain/308b6fc991d2b65a0bf410fb968f1c7b81b4a83b

Make Packages & Sources generation optional, during Generate call

refactor a bit, extract code out of Generate() into
DoGenerate{PackagesAndSources,Contents}, add new
APT::FTPArchive::ContentsOnly option to allow skipping the generation
of Package/Source files (if they are generated e.g. by some db outside
of apt-ftparchives control)
