Force gzip compression level 6 when calculating hash of a downloaded GIT repo.
To make sure the tar->gzip->checksum chain always provides consistent result.`
The script was relying on the default compression level, which must not be
necessarily consistent among different gzip versions. The level 6 is gzip's
current default compression level.

The removal of the .git dir before creating the tarball is not anymore
just an optimization. It is necessary to make the tarball reproducible.
Also, without the removal, large tarballs (gigabytes) would be created
for some linux trees.

On most distros, the tar format defaults to GNU. However, at build time
the default format may be changed to posix. Also, future versions of
tar will default to posix.
Since we want the tarballs created by the git download method to be
reproducible (so their hash can be checked), we should explicitly
specify the format. Since existing tarballs on sources.buildroot.org
use the GNU format, and also the existing hashes in the *.hash files
are based on GNU format tarballs, we use the GNU format.
In addition, the Posix format encodes atime and ctime as well as mtime,
but tar offers no option like --mtime to override them. In the GNU
format, atime and ctime are only encoded if the --incremental option is
given.

Currently, there are two failure paths in the wrapper:
- if the tar fails, then the error is ignored because it is on the
left-hand-side of a pipe;
- if the find fails, then the error is ignored because it is a
process substitution (and there is a pipe, too).
While the former could be fixed with "set -o pipefail", the latter can
not be fixed thusly and we must use an intemediate file for it.
So, fix both issues by using intermediate files, both to generate the
list of files to include in the archive, and generate the archive in a
temporary tarball.

unknown reason:

Some git repositories may be split into a master repository and
submodules. Up until now, we did not have support for submodules,
because we were using bare clones, in which it is not possible to
update the list of submodules.
Now that we are using plain clones with a working copy, we can retrieve
the submdoules.
Add an option to the git download helper to kick the update of
submodules, so that they are only fetched for those packages that
require them. Also document the existing -q option at the same time.
Submodules have a .git file at their root, which contains the path to
the real .git directory of the master repository. Since we remove it,
there is no point in keeping those .git files either.
Note: this is currently unused, but will be enabled with the follow-up
patch that adds the necessary parts in the pkg-generic and pkg-download
infrastructures.

We currently use git-archive to generate the tarball. This is all handy
and dandy, but git-archive does not support submodules. In the follow-up
patch, we're going to handle submodules, so we would not be able to use
git-archive.
Instead, we manually generate the archive:
- extract the tree to the requested cset,
- get the date of the commit to store in the archive,
- store only numeric owners,
- store owner and group as 0 (zero, although any arbitrary value would
have been fine, as long as it's a constant),
- sort the files to store in the archive.
We also get rid of the .git directory, because there is no reason to
keep it in the context of Buildroot. Some people would love to keep it
so as to speed up later downloads when updating a package, but that is
not really doable. For example:
- use current Buildroot
- it would need foo-12345, so do a clone and keep the .git in the
generated tarball
- update Buildroot
- it would need foo-98765
For that second clone, how could we know we would have to first extract
foo-12345 ? So, the .git in the archive is pretty much useless for
Buildroot.

Currently, we are using bare clones, so as to minimise the disk usage,
most notably for largeish repositories such as the one for the Linux
kernel, which can go beyond the 1GiB barrier.
However, this precludes updating (and thus using) the submodules, if
any, of the repositories, as a working copy is required to use
submodules (becaue we need to know the list of submodules, where to find
them, where to clone them, what cset to checkout, and all those is
dependent upon the checked out cset of the father repository).
Switch to using /plain/ clones with a working copy.
This means that the extra refs used by some forges (like pull-requests
for Github, or changes for gerrit...) are no longer fetched as part of
the clone, because git does not offer to do a mirror clone when there is
a working copy.
Instead, we have to fetch those special refs by hand. Since there is no
easy solution to know whether the cset the user asked for is such a
special ref or not, we just try to always fetch the cset requested by
the user; if this fails, we assume that this is not a special ref (most
probably, it is a sha1) and we defer the check to the archive creation,
which would fail if the requested cset is missing anyway.

The way we use it, gzip will store the current time in the header, which
leads to unreproducible archives.
Fix that by telling gzip to not store the name and date of the file it
compresses, with the -n option. Since it compresses its stdin, there was
already no filename stored; now there's even no date stored.
Note: gzip has had -n since at least 1.2.4, released in 1993, so

In efe7f68 (support/download: generate reproducible Bazaar archives),
bzr was instructed to store files with the timestamp set to the date
they were last modified in the repository, instead of the current date,
using the --per-file-timestamp option.
However, this option has been added only in bzr-2.2 (August 2010) which
is not available on older distros.
We fix that by not using --per-file-timestamp when the bzr version is
older than 2.2, in which case we just generate the archive with the
current date set on files.
This means the archive is thus non-reproducible, and if a hash is
available for that archive, the hash will not match, and Buildroot will
try to download from the mirror (if any) or fail (if no mirror).

Similarly to what has previously been done for the Hg download backend,
instruct bzr to generate the archive on stdout, so that we can generate

When instructing bzr to generate the output file by itself, it uses a
temporary file that is then fed to gzip, which in turn stores the
timestamp of that file in the generated archive, whereas when the output
is generated on stdout, there is no timestamp, so the archive is then
reproducible.

When hg directly creates the output file, the hash for that file changes
everytime.
However, if we just tell hg to output the archive on stdout and we do
the redirect to the file, then the archive is reproducible.
(The reason is that in the first case, a temporary file is created and
then compressed, and gzip is adding the filename and its timestamp in
the gzip header, while in the second case, there is no temporary file,
and thus no timestamp and thus it is reproducible.)

Some users may provide custom download commands with spaces in their
arguments, like so:
BR2_HG="hg --config foo.bar='some space-separated value'"
However, the way we currently call those commands does not account
for the extra quotes, and each space-separated part of the command is
interpreted as separate arguments.
Fix that by calling 'eval' on the commands.
Because of the eval, we must further quote our own arguments, to avoid
the eval further splitting them in case there are spaces (even though
we do not support paths with spaces, better be clean from the onset to
avoid breakage in the future).
We change all the wrappers to use a wrapper-function, even those with
a single call, so they all look alike.
Note that we do not single-quote some of the variables, like ${verbose}
because it can be empty and we really do not want to generate an
empty-string argument. That's not a problem, as ${verbose} would not
normally contain space-separated values (it could get set to something
like '-q -v' but in that case we'd still want two arguments, so that's
fine).

This is because, in Mercurial, tags are commits like the others, and
when we clone, we actively request a tag. But then, the server
"dereferences" that tag and sends us the revision pointed to by that
tag. Of course, since the tag is a commit after the revision we got,

This can be used for archives downloaded from a repository, like a

This will come in handy when we'll eventually make hashes mandatory as
soon as a .hash file exists: for some packages, like gcc, some versions
are downloaded as archives from upstream, while other versions may come
from a GitHub repository (via the github herlper).
In this case, a .hash file would exist, that contains hashes for the
downloaded tarballs, but archives downloaded from the repository would
not have a hash (since it is currently not possible to have reproducible
such archives). So, we'd need a way to explicitly state there is no

design no hash to check the download against.
Since we're going to have hash checking mandatory when a hash file

In some cases, upstream just update their releases in-place, without
renaming them. When that package is updated in Buildroot, a new hash to
match the new upstream release is included in the corresponding .hash
file.
As a consequence, users who previously downloaded that package's tarball
with an older version of Buildroot, will get stuck with an old archive
for that package, and after updating their Buildroot copy, will be greeted
with a failed download, due to the local file not matching the new
hashes.
Also, an upstream would sometime serve us HTML garbage instead of the
actual tarball we requested, like SourceForge does from time for as-yet
unknown reasons.
So, to avoid this situation, check the hashes prior to doing the
download. If the hashes match, consider the locally cached file genuine,
and do not download it. However, if the locally cached file does not
match the known hashes we have for it, it is promptly removed, and a
download is re-attempted.
Note: this does not add any overhead compared to the previous situation,
because we were already checking hashes of locally cached files. It just
changes the order in which we do the checks. For the records, here is the
overhead of hashing a 231MiB file (qt-everywhere-opensource-src-4.8.6.tar.gz)
on a core-i5 @2.5GHz:
cache-cold cache-hot
sha1 1.914s 0.762s
sha256 2.109s 1.270s
But again, this overhead already existed before this patch.

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.]

Instead of repeating the same test again and again in all our download
rules, just delegate the check for an already downloaded file to the
download wrapper.
This clears up the path for doing the hash checks on a cached file
before the download.

Instead of relying on argument ordering, use actual options in the
download wrapper.
Download backends (bzr, cp, hg...) are left as-is, because it does not
make sense to complexify them, since they are almost very trivial shell
scripts, and adding option parsing would be really overkill.
This commit also renames the script to dl-wrapper so it looks better in
the traces, and it is not confused with another wrapper.

The argument are correctly used, but incorrectly documented.
Inverse the comments to match the actual usage.

Not all systems have /bin/bash (e.g. NixOS[1] doesn't). Buildroot
already uses /usr/bin/env shebangs for other interpreters (perl,
python), so why not bash?
This changes only the shebangs used by Buildroot itself; stuff installed
to the target system is left unchanged.
With this applied I can run Buildroot unmodified on NixOS.

The git helper uses gzip to compress the intermediate tarball. But gzip
removes the source file, and create a new file named by appending .gz to
the original file name.
Thus, we end up with output.gz, while the download wrapper expects jsut
output, and thus believes the downlaod failed.
Fix that by storing the tar from git to a temporary file, then pipe this
file to gzip's stdin, and redirect gzip's stdout to the output file.
