This commit deprecates profile management from the activation script.
The profile management is instead the responsibility of the driving
software, for example, the `home-manager` tool in the case of
standalone installs.
The legacy behavior is still available for backwards compatibility but
may be removed in the future.
The new behavior resolves (or moves us closer to resolving) a number
of long standing open issues:
- `home-manager switch --rollback`, which performs a rollback to the
previous Home Manager generation before activating. While it was
previously possible to accomplish this by activating an old
generation, it did always create a new profile generation.
This option has been implemented as part of this commit.
- `home-manager switch --test`, which activates the configuration but
does not create a new profile generation.
This option has _not_ been implemented here since it relies on the
current configuration being activated on login, which we do not
currently do.
- When using the "Home Manager as a NixOS module" installation method
we previously created an odd `home-manager` per-user "shadow
profile" for the user. This is no longer necessary.
This has been implemented as part of this commit.
Fixes#3450
In Nix 2.3, all GC roots must be stored under `/nix/var/nix/gcroots`,
unless `--indirect` is specified. In Nix 2.4 and above, this flag is
ignored, because all GC roots created by `--add-root` are indirect.

In most cases where this function is used, suppressing only the standard
output is more appropriate. Culling diagnostic output hides error
messages and makes debugging more difficult and confusing.
`$DRY_RUN_NULL`, which the `--silence` flag replaced, was used both for
suppressing standard output on its own, and for doing so along with
diagnostic output; however, when the `run` function was added this
distinction was lost, and both outputs would be discarded.
This reintroduces the needed functionality, and changes usages of
`--silence` to `--quiet` where previously only standard output was
suppressed, or where this should have probably been the case anyway.

These (and the `*MD` functions apart from `literalMD`) are now no-ops
in nixpkgs and serve no purpose other than to add additional noise and
potentially mislead people into thinking unmarked DocBook documentation
will still be accepted.
Note that if backporting changes including documentation to 23.05,
the `mdDoc` calls will need to be re-added.

This process was automated by [my fork of `nix-doc-munge`]. All
conversions were automatically checked to produce the same DocBook
result when converted back, modulo minor typographical/formatting
differences on the acceptable-to-desirable spectrum.

Specifically, if the global per-user profiles path do not exist and we
cannot create it during the activation, then place our profile in the
Home Manager data directory. We prefer to use the global location,
though, since it makes it visible to `nix-collect-garbage`.
This is intended to improve compatibility with Nix version 2.14 and
later, which no longer creates the per-user directories.
Also, use the Home Manager data directory to manage the gcroot for the
current generation. It does not have to sit in the global per-user
gcroots directory since it should never be eligible for GC.
Before this change, a warning would be printed to the console if you
tried to manage a file in a path containing a space. For example,
`vscodium`'s `userSettings` file on Darwin is at
`~/Library/Application Support/VSCodium/User/settings.json`.
Previously, the comparison would not handle directory comparison
correctly, always finding that the source and target differed. This
would trigger the `onChange` script on each activation.
Fixes#2004
The previous implementation would allow variables to sneak into the
file names. This commit makes sure the resulting target file path
exactly matches the expected path.
Using this function it is possible to make `home.file` create a
symlink to a path outside the Nix store. For example, a Home Manager
configuration containing
home.file."foo".source = config.lib.file.mkOutOfStoreSymlink ./bar;
would upon activation create a symlink `~/foo` that points to the
absolute path of the `bar` file relative the configuration file.
PR #1211
Enabling this flag for a `home.file` entry causes the target to be
unconditionally overwritten. The option is not visible in
documentation for now and shouldn't be relied on for general use.
This change makes use of the `extend` function inside `lib` to inject
a new `hm` field containing the Home Manager library functions. This
simplifies use of the Home Manager library in the modules and reduces
the risk of accidental infinite recursion.
PR #994
In the case where `/nix` is a link, for example, on macOS Catalina,
`builtins.storeDir` returns `/nix`, not the canonical location.
This causes tests on existing files to result in Home Manager thinking
those files are outside of the store.
This change uses `readlink` on the store path so that the tests work
as intended.
When a configuration file would be written to an existing file, rather
than failing switch (and having the user have to move or delete those
files), move the files automatically to a new path.
Closes#585
Add parens to expression so the `-exec` includes files matching both.
Otherwise (before this change) the `-exec` is only invoked for
links (`-type l`):
file or (link -> doexec)
=>
(file or link) -> doexec
In particular support source files whose name start with `.` or
contain characters not allowed in the nix store, such as spaces.
Also add some test cases for `home.file`.
In particular, don't bother attempting to do substitution of the home
files and home generation derivations since these rarely, if ever,
could be substituted.
Fixes#330
Unfortunately systemd derives nonsensical unit names when the unit
file is a link to a link to a file. This commit ensures that any file
whose target path matches the pattern `*/systemd/user/*` will be
reachable with only one link hop.
This also reverts f52ec0df7c, which
contained a temporary fix. This commit is an improvements in that it
is more explicit and also handles unit files given directly as a home
file source.
