This PR ensures that we'll get a comprehensible error message whenever an old
version of Spack tries to use a DB or a lockfile that is "too new".
* Fix error message when using a too new DB
* Add a unit-test to ensure we have a comprehensible error message
|
|
Add a section to the lock file to track the Spack version/commit that produced
an environment. This should (eventually) enhance reproducibility, though we
do not currently do anything with the information. It just adds to provenance
at the moment.
Changes include:
- [x] adding the version/commit to `spack.lock`
- [x] refactor `spack.main.get_version()
- [x] fix a couple of environment lock file-related typos

Flags are encoded differently from other variants, and they need a choice rule to
ensure clingo has a choice to impose (or not) a constraint.
|
|
The flags --mirror-name / --mirror-url / --directory were deprecated in
favor of just passing a positional name, url or directory, and letting spack
figure it out.

Prior to this PR, the HOMEDRIVE environment variable was used to
detect what drive we are operating in. This variable is not available
for service account logins (like what is used for CI), so switch to
extracting the drive from PROGRAMFILES (which is more-widely defined).

On Windows, several commonly available system tools for decompression
are unreliable (gz/bz2/xz). This commit refactors `decompressor_for`
to call out to a Windows or Unix-specific method:
* The decompressor_for_nix method behaves the same as before and
generally treats the Python/system support options for decompression
as interchangeable (although avoids using Python's built-in tar
support since that has had issues with permissions).
* The decompressor_for_win method can only use Python support for
gz/bz2/xz, although for a tar.gz it does use system support for
untar (after the decompression step). .zip uses the system tar
utility, and .Z depends on external support (i.e. that the user
has installed 7zip).
A naming scheme has been introduced for the various _decompression
methods:
* _system_gunzip means to use a system tool (and fail if it's not
available)
* _py_gunzip means to use Python's built-in support for decompressing
.gzip files (and fail if it's not available)
* _gunzip is a method that can do either

(#34236)
This is a refactor of Spack's stand-alone test process to be more spack- and pytest-like.
It is more spack-like in that test parts are no longer "hidden" in a package's run_test()
method and pytest-like in that any package method whose name starts test_
(i.e., a "test" method) is a test part. We also support the ability to embed test parts in a
test method when that makes sense.
Test methods are now implicit test parts. The docstring is the purpose for the test part.
The name of the method is the name of the test part. The working directory is the active
spec's test stage directory. You can embed test parts using the test_part context manager.
Functionality added by this commit:
* Adds support for multiple test_* stand-alone package test methods, each of which is
an implicit test_part for execution and reporting purposes;
* Deprecates package use of run_test();
* Exposes some functionality from run_test() as optional helper methods;
* Adds a SkipTest exception that can be used to flag stand-alone tests as being skipped;
* Updates the packaging guide section on stand-alone tests to provide more examples;
* Restores the ability to run tests "inherited" from provided virtual packages;
* Prints the test log path (like we currently do for build log paths);
* Times and reports the post-install process (since it can include post-install tests);
* Corrects context-related error message to distinguish test recipes from build recipes.

fixes #22341
Using double quotes creates issues with shell variable substitutions,
in particular when the manifest has "definitions:" in it. Use single
quotes instead.

(#36286)
Add a "require" directive to packages, which functions exactly like
requirements specified in packages.yaml (uses the same fact-generation
logic); update both to allow making the requirement conditional.
* Packages may now use "require" to add constraints. This can be useful
for something like "require(%gcc)" (where before we had to add a
conflict for every compiler except gcc).
* Requirements (in packages.yaml or in a "require" directive) can be
conditional on a spec, e.g. "require(%gcc, when=@1.0.0)" (version
1.0.0 can only build with gcc).
* Requirements may include a message which clarifies why they are needed.
The concretizer assigns a high priority to errors which generate these
messages (in particular over errors for unsatisfied requirements that
do not produce messages, but also over a number of more-generic
errors).

## Version types, parsing and printing
- The version classes have changed: `VersionBase` is removed, there is now a
`ConcreteVersion` base class. `StandardVersion` and `GitVersion` both inherit
from this.
- The public api (`Version`, `VersionRange`, `ver`) has changed a bit:
1. `Version` produces either `StandardVersion` or `GitVersion` instances.
2. `VersionRange` produces a `ClosedOpenRange`, but this shouldn't affect the user.
3. `ver` produces any of `VersionList`, `ClosedOpenRange`, `StandardVersion`
or `GitVersion`.
- No unexpected type promotion, so that the following is no longer an identity:
`Version(x) != VersionRange(x, x)`.
- `VersionList.concrete` now returns a version if it contains only a single element
subtyping `ConcreteVersion` (i.e. `StandardVersion(...)` or `GitVersion(...)`)
- In version lists, the parser turns `@x` into `VersionRange(x, x)` instead
of `Version(x)`.
- The above also means that `ver("x")` produces a range, whereas
`ver("=x")` produces a `StandardVersion`. The `=` is part of _VersionList_
syntax.
- `VersionList.__str__` now outputs `=x.y.z` for specific version entries,
and `x.y.z` as a short-hand for ranges `x.y.z:x.y.z`.
- `Spec.format` no longer aliases `{version}` to `{versions}`, but pulls the
concrete version out of the list and prints that -- except when the list is
is not concrete, then is falls back to `{versions}` to avoid a pedantic error.
For projections of concrete specs, `{version}` should be used to render
`1.2.3` instead of `=1.2.3` (which you would get with `{versions}`).
The default `Spec` format string used in `Spec.__str__` now uses
`{versions}` so that `str(Spec(string)) == string` holds.
## Changes to `GitVersion`
- `GitVersion` is a small wrapper around `StandardVersion` which enriches it
with a git ref. It no longer inherits from it.
- `GitVersion` _always_ needs to be able to look up an associated Spack version
if it was not assigned (yet). It throws a `VersionLookupError` whenever `ref_version`
is accessed but it has no means to look up the ref; in the past Spack would
not error and use the commit sha as a literal version, which was incorrect.
- `GitVersion` is never equal to `StandardVersion`, nor is satisfied by it. This
is such that we don't lose transitivity. This fixes the following bug on `develop`
where `git_version_a == standard_version == git_version_b` does not imply
`git_version_a == git_version_b`. It also ensures equality always implies equal
hash, which is also currently broken on develop; inclusion tests of a set of
versions + git versions would behave differently from inclusion tests of a
list of the same objects.
- The above means `ver("ref=1.2.3) != ver("=1.2.3")` could break packages that branch
on specific versions, but that was brittle already, since the same happens with
externals: `pkg@1.2.3-external` suffixes wouldn't be exactly equal either. Instead,
those checks should be `x.satisfies("@1.2.3")` which works both for git versions and
custom version suffixes.
- `GitVersion` from commit will now print as `<hash>=<version>` once the
git ref is resolved to a spack version. This is for reliability -- version is frozen
when added to the database and queried later. It also improves performance
since there is no need to clone all repos of all git versions after `spack clean -m`
is run and something queries the database, triggering version comparison, such
as potentially reuse concretization.
- The "empty VerstionStrComponent trick" for `GitVerison` is dropped since it wasn't
representable as a version string (by design). Instead, it's replaced by `git`,
so you get `1.2.3.git.4` (which reads 4 commits after a tag 1.2.3). This means
that there's an edge case for version schemes `1.1.1`, `1.1.1a`, since the
generated git version `1.1.1.git.1` (1 commit after `1.1.1`) compares larger
than `1.1.1a`, since `a < git` are compared as strings. This is currently a
wont-fix edge case, but if really required, could be fixed by special casing
the `git` string.
- Saved, concrete specs (database, lock file, ...) that only had a git sha as their
version, but have no means to look the effective Spack version anymore, will
now see their version mapped to `hash=develop`. Previously these specs
would always have their sha literally interpreted as a version string (even when
it _could_ be looked up). This only applies to databases, lock files and spec.json
files created before Spack 0.20; after this PR, we always have a Spack version
associated to the relevant GitVersion).
- Fixes a bug where previously `to_dict` / `from_dict` (de)serialization would not
reattach the repo to the GitVersion, causing the git hash to be used as a literal
(bogus) version instead of the resolved version. This was in particularly breaking
version comparison in the build process on macOS/Windows.
## Installing or matching specific versions
- In the past, `spack install pkg@3.2` would install `pkg@=3.2` if it was a
known specific version defined in the package, even when newer patch releases
`3.2.1`, `3.2.2`, `...` were available. This behavior was only there because
there was no syntax to distinguish between `3.2` and `3.2.1`. Since there is
syntax for this now through `pkg@=3.2`, the old exact matching behavior is
removed. This means that `spack install pkg@3.2` constrains the `pkg` version
to the range `3.2`, and `spack install pkg@=3.2` constrains it to the specific
version `3.2`.
- Also in directives such as `depends_on("pkg@2.3")` and their when
conditions `conflicts("...", when="@2.3")` ranges are ranges, and specific
version matches require `@=2.3.`.
- No matching version: in the case `pkg@3.2` matches nothing, concretization
errors. However, if you run `spack install pkg@=3.2` and this version
doesn't exist, Spack will define it; this allows you to install non-registered
versions.
- For consistency, you can now do `%gcc@10` and let it match a configured
`10.x.y` compiler. It errors when there is no matching compiler.
In the past it was interpreted like a specific `gcc@=10` version, which
would get bootstrapped.
- When compiler _bootstrapping_ is enabled, `%gcc@=10.2.0` can be used to
bootstrap a specific compiler version.
## Other changes
- Externals, compilers, and develop spec definitions are backwards compatible.
They are typically defined as `pkg@3.2.1` even though they should be
saying `pkg@=3.2.1`. Spack now transforms `pkg@3` into `pkg@=3` in those cases.
- Finally, fix strictness of `version(...)` directive/declaration. It just does a simple
type check, and now requires strings/integers. Floats are not allowed because
they are ambiguous `str(3.10) == "3.1"`.

`spack buildcache create` is a misnomer cause it's the only way to push to
an existing buildcache (and it in fact calls binary_distribution.push).
Also we have `spack buildcache update-index` but for create the flag is
`--rebuild-index`, which is confusing (and also... why "rebuild"
something if the command is "create" in the first place, that implies it
wasn't there to begin with).
So, after this PR, you can use either
```
spack buildcache create --rebuild-index
```
or
```
spack buildcache push --update-index
```
Also, alias `spack buildcache rebuild-index` to `spack buildcache
update-index`.

Spack never parsed `nagfor` linker arguments put on the compiler line:
```
nagfor -Wl,-Wl,,-rpath,,/path
````
so, let's continue not attempting to parse that.

`buildcache create --rel`: deprecate this because there is no point in
making things relative before tarballing; on install you need to expand
`$ORIGIN` / `@loader_path` / relative symlinks anyways because some
dependencies may actually be in an upstream, or have different
projections.
`buildcache install --allow-root`: this flag was propagated through a
lot of functions but was ultimately unused.

This switches the default Make build type to `build_type=Release`.
This offers:
- higher optimization level, including loop vectorization on older GCC
- adds NDEBUG define, which disables assertions, which could cause speedups if assertions are in loops etc
- no `-g` means smaller install size
Downsides are:
- worse backtraces (though this does NOT strip symbols)
- perf reports may be useless
- no function arguments / local variables in debugger (could be of course)
- no file path / line numbers in debugger
The downsides can be mitigated by overriding to `build_type=RelWithDebInfo` in `packages.yaml`,
if needed. The upside is that builds will be MUCH smaller (and faster) with this change.

This ensures that:
a) no externals are added to the tarball metadata file
b) no externals are added to the prefix to prefix map on install, also
for old tarballs that did include externals
c) ensure that the prefix -> prefix map is always string to string, and
doesn't contain None in case for some reason a hash is missing

a) It's used by site administrators, so it's niche
b) If it's used by site administrators, they likely need to modify the config anyhow, so the default config only serves as an example to get started

Change the signature of the Environment.__init__ method to have
a single argument, i.e. the directory where the environment manifest
is located. Initializing that directory is now delegated to a function
taking care of all the error handling upfront. Environment objects
require a "spack.yaml" to be available to be constructed.
Add a class to manage the environment manifest file. The environment
now delegates to an attribute of that class the responsibility of keeping
track of changes modifying the manifest. This allows simplifying the
updates of the manifest file, and helps keeping in sync the spec lists in
memory with the spack.yaml on disk.

Spack comes to a crawl post-install of nvhpc, which is partly thanks to
this post install hook which has a lot of redundancy, and isn't correct.
1. There's no need to store "type" because that _is_ "mode".
2. There are more file types than "symlink", "dir", "file".
3. Don't checksum device type things
4. Don't run 3 stat calls (exists, stat, isdir/islink), but one lstat
call
5. Don't read entire files into memory
I also don't know why `spack.crypto` wasn't used for checksumming, but I
guess it's too late for that now. Finally md5 would've been the faster
algorithm, which would've been fine given that a non cryptographicall
checksum was used anyways.
