A leading / in paths in a .gitignore file matches the beginning of the
path, meaning that for patterns without slashes, git will match files
only in the current directory as opposed to in any subdirectory.
Prefix relevant paths with / in .gitignore files, to prevent
accidentally ignoring files in subdirectories and possibly slightly
improve the performance of "git status".
Often Linux systems are shipped with wget(1) by default (and no curl).
Many BSDs, macOS, and e.g. some Linux minimal/container images
comes with curl(1) (and no wget).
Attempting to download with curl if wget is not available increases
the likelihood for this to succeed.
Many of the external links found in the notmuch source can be resolved
using https instead of http. This changeset addresses as many as i
could find, without touching the e-mail corpus or expected outputs
found in tests.
It turns out to be inconvenient to delete the downloaded datafiles with
distclean, so I propose a new target which does that instead.
The closest conventional target is 'maintainer-clean'; the difference
here is that having the original source tarball is not enough to
reconstruct these files.
The checksum file is used by the test infrastructure to verify the downloaded
test database is the one we had in mind. Note that this test is
rather strict, and the the checksum file needs to be recommitted when
the database is regenerated.
add a pattern .gitignore to ignore the actual databases
