Especially as a new user it is a much better experience to receive a
proper help response to `-h`. Currently passing `-h` will cause some
runtime error with the `git remote` error help being shown. Not very
helpful.
It doesn't hurt to be a bit more user friendly in this case.
This is useful when running tools like NixOps or nix-review
on workstations where the upload to the builder is significantly
slower then downloading the source on the builder itself.
The script would parse the output of `git submodule status` but
didn't handle paths with spaces in them. This would result in the
following error when trying to determine the URL of the submodule:
error: key does not contain a section: .url
Summary:
According to git-submodule manpage,
"git submodule status" prefixes the hash with a '-' if it is not
initialized, and other chars in other circumstances.
(this is consistent on the various git versions tested)
nix-prefetch-git runs "git submodule init" which does you'd think,
but apparently despite this earlier versions of git before 2.16
would still give the hash the '-' suffix.
In particular this is the behavior when using 2.15 and 2.14.1
from the nixos-17.09 and nixos-17.03 channels respectively.
The script then used awk to drop the first char of the first field
which does the wrong thing when there is no prefix emitted:
while there is a space character before the hash, this is not
part of the field and so we ended up eating the first character
of the hash.
To fix this in a way that also works with the previous behavior,
this commit instead uses awk to grab the hash field
and uses tr to delete any '-' chars should they be present.
This seems to work in my testing, and for example can now
successfully fetch the source for "nginxModules.brotli"
where previously it would generate an error:
fatal: '22564a95d9ab58865a096b8d9f7324ea5f2e03e' is not a commit and a branch 'fetchgit' cannot be created from it
(we dropped a '2' from the beginning of the hash)
Currently we wrap ssh so it can find the config file passed in by
<ssh-config-file>. If one however uses ProxyCommand ssh, then ssh that
is on PATH is taken (which is also unavailable when using nix-shell
--pure), which is the plain ${openssh}/bin/ssh.
This commit makes sure our wrapped ssh is available on PATH.
They're additional commits from #26877.
Changing names of the fetched stuff was changing very many hashes,
and I think it's better to avoid that for the moment to reduce work
needed by nixpkgs users. The fetchers are expected to be commonly
used even outside nixpkgs, and the current naming wasn't that bad
usually.
(commit analogical to d10c3cc5eedf58e80e2; I haven't noticed the part of
the PR has already got to master)
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 2ca8833383.
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.
Reported by Michael Alan Dorman <mdorman@ironicdesign.com>.
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 205fb0c87e.
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.
