Instead of repeating the check in our download rules, delegate the check
of the hashes to the download wrapper.
This needs three different changes:
- add a new argument to the download wrapper, that is the full path to
the hash file; if the hash file does not exist, that does not change
the current behaviour, as the existence of the hash file is checked
for in the check-hash script;
- add a third argument to the check-hash script, to be the basename of
the file to check; this is required because we no longer check the
final file with the final filename, but an intermediate file with a
temporary filename;
- do the actual call to the check-hash script from within the download
wrapper.
This further paves the way to doing pre-download checks of the hashes
for the locally cached files.
Note: this patch removes the check for hashes for already downloaded
files, since the wrapper script exits early. The behaviour to check
localy cached files will be restored and enhanced in the following
patch.
[Thomas: fix minor typo in comment.]

# The DOWNLOAD_* helpers are in charge of getting a working copy
|
|
# of the source repository for their corresponding SCM,
|
|
# checking out the requested version / commit / tag, and create an
|
|
# archive out of it. DOWNLOAD_SCP uses scp to obtain a remote file with
|
|
# ssh authentication. DOWNLOAD_WGET is the normal wget-based download
|
|
# mechanism.
|
|
#
|
|
# The SOURCE_CHECK_* helpers are in charge of simply checking that the source
|
|
# is available for download. This can be used to make sure one will be able
|
|
# to get all the sources needed for one's build configuration.
|
|
#
|
|
# The SHOW_EXTERNAL_DEPS_* helpers simply output to the console the names
|
|
# of the files that will be downloaded, or path and revision of the
|
|
# source repositories, producing a list of all the "external dependencies"
|
|
# of a given build configuration.
