2. The parent of a failed child process in build_environment.fork no longer
calls sys.exit - instead it raises a CommandError (from [1])
3. test-install command now attempts to install all packages even if one fails
command by having it consume exactly 1 positional argument (i.e. by removing
"nargs=argparse.REMAINDER") but this does not work when configuring dependencies
of a top-level package (which show up as additional positional args). Instead
now there is an explicit check to ensure there is only 1 top-level package.
argument). The default path is [package id].xml in the CWD where test-install
is called from.
2. Fixed a bug with package.build_log_path (which was added in this branch).
3. keep_stage for package.do_install is now set. This allows uninstalling and
reinstalling packages without (re) downloading them.
Also even though I calculated which installs are new (e.g. vs. packages that
have already been installed by a previous command) I forgot to make use of that
in create_test_output (so I was always generating test output even if a package
had been installed before running the test-install command).
Note to avoid confusion: the 'handled' variable (removed in this commit) did not
serve the same purpose as 'newInstalls': it was originally required because the
recursive approach would visit the same dependency twice if more than one
package depended on it.
packages are specified and a prior one fails, it will prevent any of the others
from succeeding (and generating test output) even if they don't share
dependencies.
the original intent was to generate output as if each package was a unit test,
but I noticed that I was only generating test output for top-level packages.
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.
