Fixes #1339.
|
|
In particular, this disallows attribute names containing dots or
starting with dots. Hydra already disallowed these. This affects the
following packages in Nixpkgs master:
2048-in-terminal
2bwm
389-ds-base
90secondportraits
lispPackages.3bmd
lispPackages.hu.dwim.asdf
lispPackages.hu.dwim.def
Closes #1342.

nix-channel: error out if direct tarball unpack fails.

These are no longer used anywhere.
|
|
|
|
This dumps the entire Nix configuration, including all options that
have default values.
|
|
This makes all config options self-documenting.
Unknown or unparseable config settings and --option flags now cause a
warning.
|
|
|
|
|
|
|
|
The typical use is to inherit Config and add Setting<T> members:
class MyClass : private Config
{
Setting<int> foo{this, 123, "foo", "the number of foos to use"};
Setting<std::string> bar{this, "blabla", "bar", "the name of the bar"};
MyClass() : Config(readConfigFile("/etc/my-app.conf"))
{
std::cout << foo << "\n"; // will print 123 unless overriden
}
};
Currently, this is used by Store and its subclasses for store
parameters. You now get a warning if you specify a non-existant store
parameter in a store URI.

Move note about float support out of the wrong release notes
|
|
Looks like this snuck into the 1.11 release notes post-release, but
float support isn't actually present until 1.12.

Process nix.conf options in "new" commands, add test
|
|
Somehow this came back after d1da6967b8891763ce04d668027cf300c9bbf0b2.

It's very unlikely a path ending in .tar.gz is a directory
Fixes #1318

Thanks @copumpkin.

Default to 5 download retries
|
|
Add CURLE_WRITE_ERROR as a transient error condition
|
|
We've observed it failing downloads in the wild and retrying the same URL
a few moments later seemed to fix it.
|
|
This should help certain downloaders that don't request anything special
for the number of retries, like nix-channel.
|
|
|
|
Also, possible fix for #1310 on 32-bit systems.
|
|
Using the empty string is likely to be ambiguous in some contexts.
|
|
Timeout tests rely on failed build to determine success,
so make sure these derivations (silent in particular)
don't fail regardless of timeout behavior.
|
|
Without this (minor) change, the options set using "--option"
or read from nix.conf were parsed but not used.
|
|
Retry downloads on transient SSL errors too
|
|
|
|
This provides a significant speedup, e.g. 64 s -> 12 s for
nix-build --dry-run -I nixpkgs=channel:nixos-16.03 '<nixpkgs/nixos/tests/misc.nix>' -A test
on a cold local and CloudFront cache.
The alternative is to use lots of concurrent daemon connections but
that seems wasteful.

This is useless because the client also caches path info, and can
cause problems for long-running clients like hydra-queue-runner
(i.e. it may return cached info about paths that have been
garbage-collected).
|
|
E.g. you can now redirect /etc/resolv.conf to a different file.
|
|
Not every distribution uses nscd.

This fixes "No such file or directory" when opening /dev/ptmx
(e.g. http://hydra.nixos.org/build/51094249).
The reason appears to be some changes to /dev/ptmx / /dev/pts handling
between Linux 4.4 and 4.9. See
https://patchwork.kernel.org/patch/7832531/.
The fix is to go back to mounting a proper /dev/pts instance inside
the sandbox. Happily, this now works inside user namespaces, even for
unprivileged users. So
NIX_REMOTE=local?root=/tmp/nix nix-build \
'<nixpkgs/nixos/tests/misc.nix>' -A test
works for non-root users.
The downside is that the fix breaks sandbox builds on older kernels
(probably pre-4.6), since mounting a devpts fails inside user
namespaces for some reason I've never been able to figure out. Builds
on those systems will fail with
error: while setting up the build environment: mounting /dev/pts: Invalid argument
Ah well.
