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.
Slightly nicer behavior when updates are somewhat far apart
(during a long linking step, perhaps) ensuring things
don't appear unresponsive.
If we wait the maximum amount for the update,
don't bother waiting another 50ms (for rate-limiting purposes)
and just check if we should quit.
This also ensures we'll notice the request to quit within 1s
if quit is signalled but there is not an udpate.
(I'm not sure if this happens or not)
This makes 'nix copy' and 'nix path-info' work on .drv store
paths. Removing special treatment of .drv files seems the most
future-proof approach given the possible removal of .drv files in the
future.
Note that 'nix build' will still build (rather than substitute) .drv
paths due to the unfortunate overloading in Store::buildPaths().
