Move hiliteMatches into a separate header
|
|
This is mostly so that we don't #include <regex> everywhere (which
adds quite a bit of compilation time).

ca: add sqlite index on `RealisationsRefs(realisationReference)`
|
|
Deleting just one will only work in the test cases where I didn’t bother
creating too many of them :p
|
|
Without the change any CA deletion triggers linear scan on large
RealisationsRefs table:
sqlite>.eqp full
sqlite> delete from RealisationsRefs where realisationReference IN ( select id from Realisations where outputPath = 1234567890 );
QUERY PLAN
|--SCAN RealisationsRefs
`--LIST SUBQUERY 1
`--SEARCH Realisations USING COVERING INDEX IndexRealisationsRefsOnOutputPath (outputPath=?)
With the change it gets turned into a lookup:
sqlite> CREATE INDEX IndexRealisationsRefsRealisationReference on RealisationsRefs(realisationReference);
sqlite> delete from RealisationsRefs where realisationReference IN ( select id from Realisations where outputPath = 1234567890 );
QUERY PLAN
|--SEARCH RealisationsRefs USING INDEX IndexRealisationsRefsRealisationReference (realisationReference=?)
`--LIST SUBQUERY 1
`--SEARCH Realisations USING COVERING INDEX IndexRealisationsRefsOnOutputPath (outputPath=?)

The feature was ctabilized in d589a6aa8a5d0c9f391400d7e0e209106e89c857.

If the derivation `foo` depends on `bar`, and they both have the same
output path (because they are CA derivations), then this output path
will depend both on the realisation of `foo` and of `bar`, which
themselves depend on each other.
This confuses SQLite which isn’t able to automatically solve this
diamond dependency scheme.
Help it by adding a trigger to delete all the references between the
relevant realisations.
Fix #5320
|
|
The test illustrates failure in issue #5320. Here derivation and
it's built input have identical CA sotre path. As a result we generate
extraneout reference to build input:
$ make installcheck
...
ran test tests/selfref-gc.sh... [PASS]
ran test tests/ca/selfref-gc.sh... [FAIL]
...

error: executing SQLite statement

constraint failed (in '/tmp/.../tests/ca/selfref-gc/var/nix/db/db.sqlite')

Otherwise the clang builds fail because the constructor of `SQLiteBusy`
inherits it, `SQLiteError::_throw` tries to call it, which fails.
Strangely, gcc works fine with it. Not sure what the correct behavior is
and who is buggy here, but either way, making it public is at the worst
a reasonable workaround

Fix the error message in case of a missing realisation
|
|
Don’t say that the derivation is CA as it might happen on a non-ca
derivation too.
Technically we could always recover _something_ for a purely
input-addressed derivation (like we already do when the `ca-derivations`
xp feature isn’t enabled), but it seems better to consistently fail −
the end-result wouldn’t really make sense anyways in most cases.
|
|
Avoid `fmt` when constructor already does it
|
|
The templating is very superficial
|
|
This ensures that use-sites properly trigger new monomorphisations on
one hand, and on the other hand keeps the main `sqlite.hh` clean and
interface-only. I think that is good practice in general, but in this
situation in particular we do indeed have `sqlite.hh` users that don't
need the `throw_` function.

Add custom to_json and from_json functions for ExperimentalFeature
|
|
nix show-config --json was serializing experimental features as ints.
nlohmann::json will automatically use these definitions to serialize
and deserialize ExperimentalFeatures.
Strictly, we don't use the from_json instance yet, it's provided for
completeness and hopefully future use.

nix repl: make symlinks with the :bl command
|
|
Requested by ppepino on the Matrix:
https://matrix.to/#/!KqkRjyTEzAGRiZFBYT:nixos.org/$Tb32BS3rVE2BSULAX4sPm0h6CDewX2hClOTGzTC7gwM?via=nixos.org&via=matrix.org&via=nixos.dev
This adds a new command, :bl, which works like :b but also creates
a GC root symlink to the various derivation outputs.
ckie@cookiemonster ~/git/nix -> ./outputs/out/bin/nix repl
Welcome to Nix 2.6.0. Type :? for help.
nix-repl> :l <nixpkgs>
Added 16118 variables.
nix-repl> :b runCommand "hello" {} "echo hi > $out"
This derivation produced the following outputs:
./repl-result-out -> /nix/store/kidqq2acdpi05c4a9mlbg2baikmzik44-hello
[1 built, 0.0 MiB DL]
ckie@cookiemonster ~/git/nix -> cat ./repl-result-out

Because of 9b41239d8fdcc3fe50febe718c15833ebc224354, a formatter can
no longer be a package *or* an app. So let's require it to be a
package for now.

Make InstallableFlake::toValue() and toDerivation() behave consistently

Add .tgz as tarball extension in documentation
|
|
There is a correctnes issue here, but #3724 will fix that. This is just
a cleanup for brevity's sake.

Support for the `tgz` shorthand was added in

`nix eval`: Add option `--read-only`
|
|
|
|
assert hash types for Git and Mercurial
|
|
When leveraging remote builders or cache in CI workloads, sometimes you need to configure nix to connect via SSH to a remote server.
It is the case for example when using nixbuild.net.
By including `openssh` package, CI should be able to reach remote builders when configured i.e. with environment variables.
|
|
In particular, this means that 'nix eval` (which uses toValue()) no
longer auto-calls functions or functors (because
AttrCursor::findAlongAttrPath() doesn't).
Fixes #6152.
Also use ref<> in a few places, and don't return attrpaths from
getCursor() because cursors already have a getAttrPath() method.
