Comparing Debian versions correctly is hard. This project allows comparing
|
|
|
|
|
existing implementation by sorting a text file containing all Debian versions
|
|
|
|
|
that have been used since 2005.
|
|
|
|
|
|
|
|
|
|
To run it, make sure you have the following packages installed:
|
|
|
|
|
|
|
|
|
|
$ sudo apt install build-essenital libdpkg-dev libapt-pkg-dev libextlib-ocaml-dev ocaml-findlib ocaml libdose3-ocaml-dev
|
|
|
|
|
|
|
|
|
|
Then execute:
|
|
|
|
|
|
|
|
|
|
$ make
|
|
|
|
|
|
|
|
|
|
The following parsers are currently tested:
|
|
|
|
|
|
|
|
|
|
- dpkg (C and Perl)
|
|
|
|
|
- apt (C++ and Python)
|
|
|
|
|
- dose3 (OCaml)
|
|
|
|
|
|
|
|
|
|
Additionally, the following parsers could be added:
|
|
|
|
|
|
|
|
|
|
- libben-ocaml (in lib/benl_base.ml and lib/benl_dpkg.c)
|
|
|
|
|
|
|
|
|
|
The following do not use their own parser:
|
|
|
|
|
|
|
|
|
|
- python-debian uses python-apt
|
|
|
|
|
- libghc-dpkg-dev uses libdpkg-dev
|
|
|
|
|
- ruby-debian uses libapt-pkg-dev
|
|
|
|
|
- dpkg-dev-el uses `dpkg --compare-versions`
|
|
|
|
|
|
|
|
|
|
Each of the scripts parses a list of versions coming from standard input, one
|
|
|
|
|
per line, and writes them in sorted ascending order to standard output, one per
|
|
|
|
|
line. Versions that compare as equal are written on the same line,
|
|
|
|
|
lexicographically sorted and separated by space. The ground truth output is
|
|
|
|
|
stored in the file `versions.sorted`.
