Calculating roots seems significantly slower on darwin compared to
linux. Checking for /profile/ links could show some false positives but
should still catch most issues.
It's pretty easy to unintentionally install a second version of nix
into the user profile when using a daemon install. In this case it
looks like nix was upgraded while the nix-daemon is probably still
unning an older version.
A protocol mismatch can sometimes cause problems when using specific
features with an older daemon. For example:
Nix 2.0 changed the way files are compied to the store. The daemon is
backwards compatible and can still handle older clients, however a 1.11
nix-daemon isn't forwards compatible.
E.g.
$ nix upgrade-nix
error: directory '/home/eelco/Dev/nix/inst/bin' does not appear to be part of a Nix profile
instead of
$ nix upgrade-nix
error: '/home/eelco/Dev/nix/inst' is not a symlink
Fix a 32-bit overflow that resulted in negative numbers being printed;
use fmt() instead of boost::format(); change -H to -h for consistency
with 'ls' and 'du'; make the columns narrower (since they can't be
bigger than 1024.0).
If the user has an object greater than 1024 yottabytes, it'll just display it as
N yottabytes instead of overflowing.
Swaps to use boost::format strings instead of std::setw and std::setprecision.
The profile present in PATH is not necessarily the actual profile
location. User profiles are generally added as $HOME/.nix-profile
in which case the indirect profile link needs to be resolved first.
/home/user/.nix-profile -> /nix/var/nix/profiles/per-user/user/profile
/nix/var/nix/profiles/per-user/user/profile -> profile-15-link
/nix/var/nix/profiles/per-user/user/profile-14-link -> /nix/store/hyi4kkjh3bwi2z3wfljrkfymz9904h62-user-environment
/nix/var/nix/profiles/per-user/user/profile-15-link -> /nix/store/6njpl3qvihz46vj911pwx7hfcvwhifl9-user-environment
To upgrade nix here we want /nix/var/nix/profiles/per-user/user/profile-16-link
instead of /home/user/.nix-profile-1-link. The latter is not a gcroot
and would be garbage collected, resulting in a broken profile.
Fixes#2175
Not ready for this yet, causes the prompt to disappear in nix repl
and more generally can overwrite non-progress-bar messages.
This reverts commit 44de71a396.
As proposed in #1634 the `nix search` command could use some
improvements. Initially 0413aeb35d added
some basic sorting behavior using `std::map`, a next step would be an
improvement of the output.
This patch includes the following changes:
* Use `$PAGER` for outputs with `RunPager` from `shared.hh`:
The same behavior is defined for `nix-env --query`, furthermore it
makes searching huge results way easier.
* Simplified result blocks:
The new output is heavily inspired by the output from `nox`, the first
line shows the attribute path and the derivaiton name
(`attribute path (derivation name)`) and the description in the second
line.
