# cabal/cfg - "Build" settings for package

#---------------------------------------------------------------------

[technotes]

1. This package  builds and installs  "cabal" 3.4.0.0 as an executable
named "cabal".

#---------------------------------------------------------------------

2. If everything is working correctly, it should  be possible to build
this package offline.  In other words, the build  procedure  shouldn't
try to download any files.

In fact, it's  probably best that DNS be turned off while this package
is being built.  This will prevent most attempts by the "build" proce-
dure to go online.

To turn DNS off:        sudo killany dnsmasq
To turn DNS back on:    sudo service dnsmasq restart

3. OldCoder says:

It wasn't easy to make this work. The initial bootstrap involved  man-
ual downloads of source tarballs for  "cabal" 2.4.0.0 dependencies and
patching  the sources because they weren't compatible with the release
of "ghc" that we were using (8.6.5).

Subsequently, we built a temporary copy of "cabal" 2.4.0.0 and used it
to download  source  tarballs for "cabal" 3.4.0.0  dependencies.  Next
step,  build a temporary copy  of "cabal" 3.4.0.0. After that, we used
"cabal" 3.4.0.0  to  download  source tarballs for  applications to be
built later (such as "pandoc").

Finally, we modified the ".cabal" tree that the two "cabals"  had cre-
ated so as to make it the equivalent of an offline source-only reposi-
tory.

Sure,  Haskell and  "cabal"  win the award for  offline build support.
Not.

#---------------------------------------------------------------------

4. This package should never be updated without review of compatibili-
ty issues  related to the exact  releases of "ghc", the bootstrap copy
of "cabal", and the final copy of "cabal" involved.

Short version: Updates mean horrible fates.
