- add links to definitions of terms
- one sentence per line
- be more specific about which store is used for the import
- clearly distinguish store paths and store objects
- make a recommendation to use `nix-copy-closure` for efficient SSH transfers
the individual commands' documentation should provide enough examples to
make sense of the options and judge what to use and when. proper guides,
which would require a more elaborate setup to show off Nix's
capabilities are out of scope for the reference manual.
* doc: convention improvements for copying closure
use -P, which only considers executables but not shell builtins

previously the test directory could have been left untouched before executing
a test when `init.sh` was not run - and sometimes it isn't
supposed to be run - which made the test suite highly stateful and thus
behaving surprisingly on multiple runs.
pararameterisation is not actually needed the way things are currently
set up, and it confused me when trying to understand what the code does.
all but one test sources vars-and-functions.sh, which nominally only
defines variables, but in practice is always coupled with the actual
initialisation. while the cleaner way of making this more legible would
be to source variables and initialisation separately, this would produce
a huge diff.
the change requires a few small fixes to keep the tests working:
- only create test home directory during initialisation
that vars-and-functions.sh wrote to the file system seems not write
- fix creation of the test directory
due to statefulness, the test home directory was implicitly creating
the test root, too. decoupling that made it apparent that this was
probably not intentional, and certainly confusing.
- only source vars-and-functions.sh if init.sh is not needed
there is one test case that only needs a helper function but no
initialisation side effects
- remove some unnecessary cleanups and split parts of re-used test code
there were confusing bits in how initialisation code was repurposed,
which break if trying to refactor the outer layers naively...
This fixes https://github.com/NixOS/nixpkgs/pull/290775 by not expanding aliases
when sourcing the stdenv setup script. The way bash handles aliases is to expand
them when a function is defined, not when it is used. I.e.:
$ alias echo="echo bar "
$ echo foo
bar foo
$ xyzzy() { echo foo; }
$ shopt -u expand_aliases
$ xyzzy
bar foo
$ xyzzy2() { echo foo; }
$ xyzzy2
foo
The problem is that ~/.bashrc is sourced before the stdenv setup, and bashrc
commonly sets aliases for ‘cp’, ‘mv’ and ‘rm’ which you don’t want to take
effect in the stdenv derivation builders. The original commit introducing this
feature (5fd8cf7667) even mentioned this very
alias.
The only way to avoid this is to disable aliases entirely while sourcing the
stdenv setup, and reenable them afterwards.

the old `copyFile` was just a wrapper that was calling the `copy`
function. This wrapper function is removed and the `copy` function is
renamed to `copyFile`.
The warning was done to handle older Nix releases that didn't have
Docker images (091f232896), but this was
a bad idea because it causes us to silently skip uploading Docker
images if e.g. Hydra hasn't finished building them yet.
Issue #10648.
In streaming mode, libarchive doesn't handle symlinks in zip files
correctly. So write the entire file to disk so libarchive can access
it in random-access mode.
Fixes#10649. This was broken in cabee98152.
* Document string context
Now what we have enough primops, we can document how string contexts
work.

builtins.strictDerivation returns an attribute set with drvPath and
output paths. For some reason, current implementation forbids drv
instead of drvPath.
Remove `isLink` in favor of `std::filesystem::is_link`
This is one step closer to eventually getting rid of most of our file system utils (in `file-system.cc`) in favor of the `std::filesystem`.
- specify meeting times in terms of a time zone rather than standard
time (the first encompasses standard time changes)
- add information on who can participate and how
- unrelated but still important: add GitHub handle to contact the team
