Signed-off-by: Leah Rowe

create a lock file during builds

2024-06-09T14:37:13+00:00

prevent duplicate main instances of the build
system from running

the lock file is deleted when the parent process
exits, alongside the tmpdir deletion

the build system must only ever be run ot one
instance at a time, per work directory

git.sh: hide e() output on for loop

2024-06-09T14:27:03+00:00

this for loop is a hack to make sure that all the
sources get nuked (using nuke.list files).

hide the messages so that they do not appear when
running just any command in the trees script.

revert this change. otherwise, nothing will download
or build

git.sh: download xtree before, not after

2024-06-09T10:55:30+00:00

downloading it after means that if an error occurs
when downloading the xtree project, the main project
will still be there and nothing will mandate the
downloading of the xtree project. whereas, if we
grab the xtree project first, then the main project
won't get saved to src/

this makes the build system a bit more resilient under
fault conditions, but otherwise doesn't change behaviour.

lib.sh: less confusing error in download()

2024-06-09T10:07:07+00:00

don't say "file missing", because it may be present!

instead, say that the download failed. this covers both
contexts: internet failed and thus no file present, or
the file is present but checksum verification failed.

lib.sh: hide stderr on download()

2024-06-09T10:04:25+00:00

on the initial check, the output is confusing because
it will say "checksum verification failed" if the
file doesn't already exist, but then goes to download.

only say checksum failed if a download occured, and the
check failed, otherwise report nothing except that the
file already exists.

this will not reduce the ability to debug issues later
on, and it will reduce the amount of confusion for users.
