In the Windows filesystem logic for creating a symlink, we intend to
fall back to a copy when the symlink cannot be created (for some
configuration settings on Windows it is not possible for the user
to create a symlink). It turns out we were overly-broad in which
exceptions lead to this fallback, and the subsequent copy would
also fail: at least one case where this occurred is when we
attempted to create a symlink that already existed.
The updated logic expressly avoids falling back to a copy when the
file/symlink already exists.

* ASP-based solver: use satisfies instead of intersects
They are semantically equivalent for concrete versions,
but the GitVersion.intersects implementation is buggy
* Mitigation for git version bug
fixes #36134
This commit works around the issue in #36134, by using
GitVersion.satisfies instead of GitVersion.intersects
There are still underlying issues when trying to infer the
"reference version" when no explicit one is given, but:
1. They are not reproducible with our synthetic repo
2. They occur only when the `git.<xxx>` form of Git version
is used
Here we just work around the user facing issue and ensure
the tests are correct with our synthetic repository.

This PR does 2 unrelated things:
1. It changes the encoding of the compilers
2. It tweaks the heuristic for the solves in a0d88179074f81d13a3fad629a43d86334e7f982
Both were initially motivated by trying to get a performance gain but, while 2 showed significant speed-ups[^1], 1 instead didn't. I kept it anyhow, since I think the code related to compilers is more consolidated with the new encoding and we might get some performance improvement out of it if we can base our errors on the `node_compiler(Package, CompilerID)` atoms instead of `attrs`.
[^1]: In general the changes in the heuristic brought a ~10% speed-up on the tests I did. I'll post detailed results below.
Add a warning about compilers.yaml that is triggered if there are multiple compilers with the same spec, os and
target (since they can't be selected by users with the spec syntax only).

Since GPG clear-sign cannot deal with lines longer than 19995 characters
and doesn't even error but simply truncates those linese (don't ask me
why...), we have to be careful not to hit that line limit when reducing
the filesize.
So, instead this PR sets the indent level to 0 and drops the whitespace
after `: `, which still reduces file size by 50% or so.

Adds builders appropriate for building these packages on Windows.
It is intended that builds on other platforms are unaffected (e.g.

... and use colors in disambiguate message for clarity.
This commit avoids the loop:
```
for root in roots:
for dep in deps(root):
...
```
instead it ensures each node is visited once and only once.
Also adds a small optimization when searching for concrete specs, since
we can assume uniqueness of dag hash, so it's fine to early exit.

Introduced in #35944
|
|
|
|
This adds a new mode for `concretizer:reuse` called `dependencies`,
which only reuses dependencies. Currently, `spack install foo` will
reuse older versions of `foo`, which might be surprising to users.

* Hotfix: Fix CI unit test after CI refactor
|
|
* CI configuration boilerplate reduction and refactor
Configuration:
- New notation for list concatenation (prepend/append)
- New notation for string concatenation (prepend/append)
- Break out configuration files for: ci.yaml, cdash.yaml, view.yaml
- Spack CI section refactored to improve self-consistency and
composability
- Scripts are now lists of lists and/or lists of strings
- Job attributes are now listed under precedence ordered list that are
composed/merged using Spack config merge rules.
- "service-jobs" are identified explicitly rather than as a batch
CI:
- Consolidate common, platform, and architecture configurations for all CI stacks into composable configuration files
- Make padding consistent across all stacks (256)
- Merge all package -> runner mappings to be consistent across all
stacks
Unit Test:
- Refactor CI module unit-tests for refactor configuration
Docs:
- Add docs for new notations in configuration.rst
- Rewrite docs on CI pipelines to be consistent with refactored CI
workflow
* Script verbose environ, dev bootstrap
* Port #35409

When untouched spec pruning is enabled, specs possibly affected
by a change cannot be pruned from a pipeline.
Previously spack looked at all specs matching changed package
names, and traversed dependents of each, all the way to the
environment root, to compute the set of environment specs
possibly affected by a change (and thus, not candidates for
pruning).
With this PR, when untouched spec pruning is enabled, a new
environment variable can control how far towards the root spack
traverses to compute the set of specs possibly affected by a
change. SPACK_UNTOUCHED_PRUNING_DEPENDENT_DEPTH can be set
to any numeric value before the "spack ci generate" command
is called to control this traversal depth parameter. Setting
it to "0" traverses only touched specs, setting it to "1"
traverses only touched specs and their direct dependents, and
so on. Omitting the variable results in the previous behavior
of traversing all the way to the root. Setting it to a negative
value means no traversal is done, and always yields an empty
set of possibly affected specs (which would result in the max
pruning possible).

Currently `spack buildcache create` creates compressed tarballs that
differ between each invocation, thanks to:
1. The gzip header containing mtime set to time.time()
2. The generated buildinfo file which has a different mtime every time.
To avoid this, you have to explicitly construct GZipFile yourself, since
the Python API doesn't expose the mtime arg, and we have to manually
create the tarinfo object for the buildinfo metadata file.
Normalize mode: regular files & hardlinks executable by user, dirs, symlinks: set 0o755 permissions in tarfile; other files use 0o644

This commit formalizes `satisfies(lhs, rhs, strict=True/False)`
and splits it into two functions: `satisfies(lhs, rhs)` and
`intersects(lhs, rhs)`.
- `satisfies(lhs, rhs)` means: all concrete specs matching the
left hand side also match the right hand side
- `intersects(lhs, rhs)` means: there exist concrete specs
matching both lhs and rhs.
`intersects` now has the property that it's commutative,
which previously was not guaranteed.
For abstract specs, `intersects(lhs, rhs)` implies that
`constrain(lhs, rhs)` works.
What's *not* done in this PR is ensuring that
`intersects(concrete, abstract)` returns false when the
abstract spec has additional properties not present in the
concrete spec, but `constrain(concrete, abstract)` will
raise an error.
To accomplish this, some semantics have changed, as well
as bugfixes to ArchSpec:
- GitVersion is now interpreted as a more constrained
version
- Compiler flags are interpreted as strings since their
order is important
- Abstract specs respect variant type (bool / multivalued)

Two fixes:
1. `-Wl,a,b,c,d` is a comma separated list of linker arguments, we
incorrectly assume key/value pairs, which runs into issues with for
example `-Wl,--enable-new-dtags,-rpath,/x`
2. `-Xlinker,xxx` is not a think, so it shouldn't be parsed.
|
|
Currently, if two compilers with the same spec differ on the flags, the concretizer will:
1. mix both sets of flags for the spec in the ASP program
2. error noting that the set of flags from the compiler (both of them) doesn't match the set from the lower priority compiler
This PR fixes both -- only flags from the highest priority compiler with a given spec are considered.

`mypy` only understands `sys.platform == "win32"`, not indirect assignments of that
value to things like `is_windows`. If we don't use the accepted platform checks, `mypy`
registers many Windows-only symbols as not present on Linux, when it should skip the
checks for platform-specific code.

if dump file existed it was not truncating the file, resulting in
a file with unaltered filesize, with the new content at the beginning,
"padded" with the tail of the old content, since the new content was
not enough to overwrite it.

`colify` is an old module in Spack that still uses `**kwargs` liberally.
We should be more explicit. Doing this eliminates the need for many
checks (can't pass the wrong arg if it isn't allowed) and makes the
function documentation more clear.

Fixes a bug introduced in 44ed0de8c077630148c213d3c7f40a8965eb6f94
where the push method of binary_distribution now takes named args
include_root and include_depedencies, to avoid the **kwarg hole.
But the call site wasn't update and we passed a dict of keys/values instead
of arguments, which resulted in a call like this:
```
push(include_root={"include_root": True, "include_dependencies": False})
```
This commit fixes that, and adds a test to see if we push the correct packages.

This error shows up a lot, typically it's harmless because an error
happened before the source build even started, in which case we don't
have build logs to copy. So, warn instead of error, cause it distracts
from the actual CI error.

Currently we attempt to setup the build environment even when
dependencies are not installed, which typically results in error while
searching for libraries or executables in a dependency's prefix.
With this change, we get a more user friendly error:

==> Error: Not all dependencies of perl are installed, cannot setup build environment:

* Allow users to specify root env dir
Environments managed by spack have some advantages over anonymous Environments
but they are tucked away inside spack's directory tree. This PR gives
users the ability to specify where the environments should live.
See #32823
This is also taken as an opportunity to ensure that all references are to "managed environments",
rather than "named environments". Prior to this PR some references to the latter persisted.

The call:
```
x.satisfies(y[, strict=False])
```
is commutative, and tests non-empty intersection, whereas:
```
x.satsifies(y, strict=True)
```
is not commutative, and tests set-inclusion.
There are 2 fast paths. When strict=False both self and other need to
be concrete, when strict=True we can optimize when other is concrete.

Spack generally ignores file-file projection clashes in environment
views, but would eventually error when linking the `.spack` directory
for two specs of the same package.
This leads to obscure errors where users have no clue what the issue is
and how to fix it. On top of that, the error comes very late, since it
happens when the .spack dir contents are linked (which happens after
everything else)
This PR improves that by doing a quick check ahead of time if clashes
are going to be anticipated (by simply checking for clashes in the
projection of each spec's .spack metadir). If there are clashes, a
human-readable error is thrown which shows two of the conflicting specs,
and tells users to user unify:true, view:false, or set up custom
projections.
