Deprecation warnings should not be used in Nixpkgs because they spam
innocent "nix-env -qa" users with (in this case) dozens of messages
that they can't do anything about.
This also reverts commit 2ca883338389b7ab995924a0cab0211993bdf1da.
This commit extends fetchFromGitHub with ability to fetch GitHub
repositories with submodules, so we can use the function consistently
with all GitHub repositories.
Note it doesn't change the previous behavior.
This fixes a regression caused by commit f56ab9e
("nix-prefetch-git: Include the date in the machine-readable [...]")
where a couple of directory paths printed by pushd/popd appeared before
the JSON output on stdout (thus breaking it). Fix it by redirecting the
extraneous output to /dev/null.

stdout, in strict ISO 8601 format.
This will be helpful for automatically updating fetchgit expressions
and the dates in version numbers associated with them.
Source of this change goes back to 2009 and original version of
fetchgit at 205fb0c87eab5dd53c6a0e97b1ff0e48f141c902.
The nondeterminism is really caused by changing .git so leave other
files alone as they might be interesting.
Note: this causes a hash mismatch with Hydra's version of Git Plugin
which we should fix to comply.
Previously, nix-prefetch-git would report the same JSON whether submodules were being fetched or not; with this change, the --fetch-submodules option will cause the JSON output to include "fetchSubmodules": true, so that fetchgit (builtins.fromJSON (builtins.readFile ./path/to/output.json)) will work.
This commit fixes#6651.
Before this change the `nix-prefetch-git` script would use a different store
name than nix's `fetchgit` function. Because of that it was not possible to
use `nix-prefetch-git` as a way to pre-populate the store (for example when
the user it using private git dependencies that needs access to the ssh agent)
The comment related to the `deepClone` and `no-deepClone` options was
misleading as these options have no relation with submodules, but on the
the depth in `git clone --depth n`.
These environment variables allow using fetchgit with git:// URLs using
the SOCKS proxy technique described in 'Using Git with a SOCKS proxy':
http://www.patthoyts.tk/blog/using-git-with-socks-proxy.html
Briefly, GIT_PROXY_COMMAND is set to a script which invokes connect[1],
which reads SOCKS_PROXY, which might be pointing to a local instance of
'ssh -D'.

If "fetcher" is a string, then Nix will execute it with bash already, so
the additional bash argument in that string was redundant and apparently
causes trouble on non-Linux platforms.
Hopefully fixes https://github.com/NixOS/nixpkgs/issues/11496.
The script's shebang depends on /usr/bin/env, which we don't have in chroot
environments. This patch remedies the fallout from ade9f7167dd1fec6, which
fixed https://github.com/NixOS/nixpkgs/issues/11284.
Close#9790.
This fixes checkouting for a nasty combination:
1. To be checkouted is a revision which corresponds to tag in a form "<tag>^{}".
2. This revision is not fetched by default.
This is useful when `leaveDotGit = true` and some other derivation
expects some branch name to exist.
Previously, `nix-prefetch-git` always created a branch with a
hard-coded name (`fetchgit`).
This patch resolves https://github.com/NixOS/nixpkgs/issues/6395. Deep
cloning is useful in combination with 'leaveDotGit' for builds that want
to run "git describe" to obtain a proper version string, etc., like the
'haskellngPackages.cabal2nix' package does.
The name detection didn't work for e.g. http://git.suckless.org/sinit/.
I tested the tarball builds now.
@shlevy claimed nixpkgs requires nix-1.8 features anyway,
so the additional check with message were superfluous.
Without this, the generated pack files are non-deterministic.
I didn't notice this issue in my earlier testing, because my test repo
had too few commits for the thread scheduling to take effect. (Test repo
had about 10 commits.)
Add more files to the delete list:
* .git/FETCH_HEAD
* .git/ORIG_HEAD
* .git/refs/remotes/origin/HEAD
* .git/config
Further, remove all remote branches, remove tags not reachable from the
given 'rev', do a full repack and then garbage collect unreferenced
objects.
According to my testing, the result is fully deterministic. As in "any
change done to the upstream repo, ahead of 'rev', will not affect the
hash of the resulting 'clone'". Even changing the clone URL will not
change the output hash, because .git/config is removed.
A new version of git can of course change store format, but that's
unavoidable.
For big repositories, the repack operation may be a bit heavy. But as
far as I can see there is no cheaper way to determinism.
