This reverts commit da68127737, reversing
changes made to 2ba494b728.
These changes are reverted because they cause an incompatibility which
they should not.
"emacsWrapper" replaces emacsWithPackages. In addition to "packagesFun",
emacsWrapper has an optional variable called "execStart". execStart can
be used to append elisp to the default site-start.el script. This is
useful for providing a way to load a user's .emacs.d/init.el
file. "emacsWithPackages" is implemented with emacsWrapper for
convenience and compatability.
Sometimes patches start without a leading prefix. We default to strip
one prefix or path component from patches (-p1) in the patchPhase in
stdenv.
As all patches should therefore be in this format, fetchpatch should
have an option to normalize patch paths. This commit introduces a new
argument to fetchpatch called addPrefixes that adds one patch prefix to
the old and new paths in a patch before putting it into the store.
fetchMavenArtifact downloads a Maven artifact given a group id, an artifact id,
and a version.
Example usage:
org_apache_httpcomponents_httpclient_4_5_2 = fetchMavenArtifact {
groupId = "org.apache.httpcomponents";
artifactId = "httpclient";
version = "4.5.2";
sha256 = "0ms00zc28pwqk83nwwbafhq6p8zci9mrjzbqalpn6v0d80hwdzqd";
# Optionally: repos = [ ... urls to some Maven repos to use ... ];
# Optionally: url, urls - pointing directly to a specific jar url.
};
Now `org_apache_httpcomponents_httpclient_4_5_2.jar` points to the downloaded
JAR file, while `org_apache_httpcomponents_httpclient_4_5_2` refers to a
derivation that when used used in `buildInputs` will be automatically added to
the Java classpath.
downloads.sourceforge.net is the official way to download tarballs from
SourceForge. However, it is reported as unreliable due to SF's weird
load balancing system.
This commit gives the official mirror utmost priority, and will use
other configured mirrors (which may be temporary) as a fallback only
when the official one can't be reached/download fails/hangs.
References: NixOs/nixpkgs#16900
This patch fixes#16614 and #16741.
The first issue was caused by the fact that both `/share` and
`/share/fish/vendor_completions.d` end in the `pathsToLink`. The
`pkgs/build-support/buildenv/builder.pl` creates `/share`, then links
`/share/fish` under `/share` and then tries to create the directory
`/share/fish/vendor_completions.d` and fails because it already exists.
The simplest way to reproduce the issue is to build the next Nix
expression:
```nix
let pkgs = import <nixpkgs> { };
in pkgs.buildEnv {
name = "buildenv-issue";
paths = [
pkgs.fish
pkgs.vim
];
pathsToLink = [
"/share"
"/share/fish/vendor_completions.d"
];
}
```
The second issue is more critical and was caused by the fact findFiles
doesn't recurse deep enough. It stops at first unique directory for the
package (e.g., "/share" or even "/") and later the scripts decides it
shouldn't link it as it doesn't match pathsToLink (e.g., "/share/fish"),
so the result is empty.
The test:
```nix
let pkgs = import <nixpkgs> { };
in pkgs.buildEnv {
name = "buildenv-issue";
paths = [
pkgs.fish
pkgs.vim
];
pathsToLink = [
"/share/fish/functions"
];
}
```
or
```nix
let pkgs = import <nixpkgs> { };
in pkgs.buildEnv {
name = "buildenv-issue";
paths = [
pkgs.vim
];
pathsToLink = [
"/share"
];
}
```
Prior to this commit, trailing whitespace would be introduced when
modifying '#!' lines with no arguments. For example (whitespace added):
/nix/store/.../foo: interpreter directive changed
from "/bin/bash"
to "/nix/store/...-bash-4.3-p42/bin/bash "
/nix/store/.../bar: interpreter directive changed
from "/bin/baz wef"
to "/nix/store/...-baz wef "
We add a sed command to strip trailing whitespace, so the above commands
would drop the two spaces after "bash", or the one space after "baz wef".
abbradar: fixed commit title
Closes#16785.
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.
stripHash uses a global variable to communicate it's computation
results, but it's not necessary. You can just pipe to stdout in a
subshell. A function mostly behaves like just another command.
baseHash() also introduces a suffix-stripping capability since it's
something the users of the function tend to use.
