# Release 2.3 (2019-09-04)
|
|
|
|
|
|
|
|
|
|
This is primarily a bug fix release. However, it makes some incompatible
|
|
|
|
|
changes:
|
|
|
|
|
|
|
|
|
|
- Nix now uses BSD file locks instead of POSIX file locks. Because of
|
|
|
|
|
this, you should not use Nix 2.3 and previous releases at the same
|
|
|
|
|
time on a Nix store.
|
|
|
|
|
|
|
|
|
|
It also has the following changes:
|
|
|
|
|
|
|
|
|
|
- `builtins.fetchGit`'s `ref` argument now allows specifying an
|
|
|
|
|
absolute remote ref. Nix will automatically prefix `ref` with
|
|
|
|
|
`refs/heads` only if `ref` doesn't already begin with `refs/`.
|
|
|
|
|
|
|
|
|
|
- The installer now enables sandboxing by default on Linux when the
|
|
|
|
|
system has the necessary kernel support.
|
|
|
|
|
|
|
|
|
|
- The `max-jobs` setting now defaults to 1.
|
|
|
|
|
|
|
|
|
|
- New builtin functions: `builtins.isPath`, `builtins.hashFile`.
|
|
|
|
|
|
|
|
|
|
- The `nix` command has a new `--print-build-logs` (`-L`) flag to
|
|
|
|
|
print build log output to stderr, rather than showing the last log
|
|
|
|
|
line in the progress bar. To distinguish between concurrent builds,
|
|
|
|
|
log lines are prefixed by the name of the package.
|
|
|
|
|
|

|
|
|
- Builds are now executed in a pseudo-terminal, and the `TERM`
|
2020-07-23 00:17:48 +03:00
|
|
|
environment variable is set to `xterm-256color`. This allows many
|
|
|
|
|
programs (e.g. `gcc`, `clang`, `cmake`) to print colorized log
|
|
|
|
|
output.
|
|
|
|
|
|
|
|
|
|
- Add `--no-net` convenience flag. This flag disables substituters;
|
|
|
|
|
sets the `tarball-ttl` setting to infinity (ensuring that any
|
|
|
|
|
previously downloaded files are considered current); and disables
|
|
|
|
|
retrying downloads and sets the connection timeout to the minimum.
|
|
|
|
|
This flag is enabled automatically if there are no configured
|
|
|
|
|
non-loopback network interfaces.
|
|
|
|
|
|
|
|
|
|
- Add a `post-build-hook` setting to run a program after a build has
|
|
|
|
|
succeeded.
|
|
|
|
|
|
|
|
|
|
- Add a `trace-function-calls` setting to log the duration of Nix
|
|
|
|
|
function calls to stderr.
