Still need to add output formatting (in a commonly parse-able format like Junit
or TAP). May want to adjust how the build log is accessed in case of a build
failure.
1. Database stores a file version, so we can add to it in the future.
2. Database indexed by hashes and not numerical indexes.
3. Specs built by database have consistent hashes and it's checked.
4. minor naming and whitespace changes.
Most importantly wrote the Lock, Read_Lock_Instance, and Write_Lock_Instance classes in lock.py
Updated the locking in database.py
TODO: Lock on larger areas
Replaced them all with references to the database
Implemented caching in the database. The database now only re-reads data
if the database file exists and was changed since this file last wrote to it.
Added the installed_db field to the spack instance
Left the call to all_specs from testdirectory_layout.py for now.
No methods use the database so far.
Also, a bug fix:
Previous version did not remove the staging directory on a failed install
This led to spack refusing to uninstall dependencies of the failed install
Added to cleanup() to blow away the staging directory on failed install.
Certain remote protocols don't support the `--depth` option. Since this can't
be checked by URL type or in any sane way locally, this version attempts to
clone git repositories with the --depth option, and if that fails attempts the
clone again without it.
Ensures all tags are ready before checkout, using `--branch` if possible and
an extra pull if that is not available. Also adds `--depth 1` to create
shallow clones if the git version is sufficient.
Fixes#64.
It is currently less painful to pull the source from github, compile it into a
gem, then install the gem, than it is to download a gem and install it. This
still lacks an activation mechanism, but `spack use tmuxinator` is functional.
- This can result in the user being prompted to download an unsafe
version.
- Avoids overly strict errors when something *could* be satisfiable
but we don't know about hte version.
