We've previously generated CI pipelines for PRs, and they rebuild any packages that don't have
a binary in an existing build cache. The assumption we were making was that ALL prior merged
builds would be in cache, but due to the way we do security in the pipeline, they aren't. `develop`
pipelines can take a while to catch up with the latest PRs, and while it does that, there may be a
bunch of redundant builds on PRs that duplicate things being rebuilt on `develop`. Until we can
do better caching of PR builds, we'll have this problem.
We can do better in PRs, though, by *only* rebuilding things in the CI environment that are actually
touched by the PR. This change computes exactly what packages are changed by a PR branch and
*only* includes those packages' dependents and dependencies in the generated pipeline. Other
as-yet unbuilt packages are pruned from CI for the PR.
For `develop` pipelines, we still want to build everything to ensure that the stack works, and to ensure
that `develop` catches up with PRs. This is especially true since we do not do rebuilds for *every* commit
on `develop` -- just the most recent one after each `develop` pipeline finishes. Since we skip around,
we may end up missing builds unless we ensure that we rebuild everything.
We differentiate between `develop` and PR pipelines in `.gitlab-ci.yml` by setting
`SPACK_PRUNE_UNTOUCHED` for PRs. `develop` will still have the old behavior.
- [x] Add `SPACK_PRUNE_UNTOUCHED` variable to `spack ci`
- [x] Refactor `spack pkg` command by moving historical package checking logic to `spack.repo`
- [x] Implement pruning logic in `spack ci` to remove untouched packages
- [x] add tests
* cmake: use CMAKE_INSTALL_RPATH_USE_LINK_PATH
Spack has a heuristic to add rpaths for packages it knows are required,
but it's really a heuristic, and it does not work when the dependencies
put their libraries in a different folder than `<prefix>/lib{64,}`.
CMake patches binaries after install with the "install rpaths", which by
default are provided by Spack and its heuristic through
`CMAKE_INSTALL_RPATH`.
CMake however knows better what libraries are effectively being linked
to, and has an option to include those in the install rpath too, through
`CMAKE_INSTALL_RPATH_USE_LINK_PATH`.
These two CMake options are complementary, repeated rpaths seem to be
filtered, and the "use link path" paths are appended to Spack's
heuristic "install rpath".
So, it seems like a good idea to enable "use link path" by default, so
that:
- `dlopen` by library name uses Spack's heuristic search paths
- linked libraries in non-standard locations within a prefix get an
rpath thanks to CMake.

We shouldn't be using "remove_linked_tree" to remove the lock file,
since that function expects to receive a directory path as an
argument.
Also, as a further measure to avoid regression, this commit restores
the "ignore_errors=True" argument on linux and adds a unit test
checking that "remove_linked_tree" doesn't change file permissions
as a side effect of a failure to remove.
Reduces the number of stat calls to a bare minimum:
- Single pass over src prefixes
- Handle projection clashes in memory
Symlinked directories in the src prefixes are now conditionally
transformed into directories with symlinks in the dst dir. Notably
`intel-mkl`, `cuda` and `qt` has top-level symlinked directories that
previously resulted in empty directories in the view. We now avoid
cycles and possible exponential blowup by only expanding symlinks that:
- point to dirs deeper in the folder structure;
- are a fixed depth of 2.
Currently `old_root` is computed by reading the symlink at `self.root`.
We should be more defensive in removing it by checking that it is in the
same directory as the new root. Otherwise, in the worst case, when
someone runs `spack env create --with-view=./view -d .` and `view`
already exists and is a symlink to `/`, Spack effectively runs `rm -rf /`.
`file` was used to detect Python scripts with shebangs, so that the interpreter could be changed from <python prefix> to <view path>. With this change, we detect shebangs using Python instead, so that `file` is no longer required.
The number of commit characters in patch files fetched from GitHub can change,
so we should use `full_index=1` to enforce full commit hashes (and a stable
patch `sha256`).
Similarly, URLs for branches like `master` don't give us stable patch files,
because branches are moving targets. Use specific tags or commits for those.
- [x] update all github patch URLs to use `full_index=1`
- [x] don't use `master` or other branches for patches
- [x] add an audit check and a test for `?full_index=1`

Known issues reports only 2 issues, among the bugs reported on GitHub.
One of the two is also outdated, since the issue has been solved
with the new concretizer. Thus, this commit removes the section.
When you install Spack from a tarball, it will always show an exact
version for Spack itself, even when you don't download a tagged commit:
```
$ wget -q https://github.com/spack/spack/archive/refs/heads/develop.tar.gz
$ tar -xf develop.tar.gz
$ ./spack-develop/bin/spack --version
0.16.2
```
This PR sets the Spack version to `0.18.0.dev0` on develop, following [PEP440](https://github.com/spack/spack/pull/25267#issuecomment-896340234) as
suggested by Adam Stewart.
```
spack (fix/set-dev-version)$ spack --version
0.18.0.dev0 (git 0.17.1-1526-e270464ae0)
spack (fix/set-dev-version)$ mv .git .git_
spack $ spack --version
0.18.0.dev0
```
- [x] Update the release guide
- [x] Add __version__ to spack's __init__.py
- [x] Use PEP 440 canonical version strings
- [x] Make spack --version output [actual version] (git version)

* Add tests to ensure google cloud storage urls work as mirrors
This commit adds two tests to track that GCS buckets can work as
mirrors, and can be parsed as valid URLs.
Currently, gs:// format URLs are not correctly parsed.
* Fix URL parsing for GCS buckets
This commit adds GCS bucket URLs as valid URLs.
* lower priority of package-provided urls
This change favors urls found in a scraped page over those provided by
the package from `url_for_version`. In most cases this doesn't matter,
but R specifically returns known bad URLs in some cases, and the
fallback path for a failed fetch uses `fetch_remote_versions` to find a
substitute. This fixes that problem.

Checksum was only actually scraping when called with no versions. It
now always scrapes and then selects URLs from the set of URLs known to

but apparently it's required by at least one mock package, so back in it
goes.

Adds `spack external read-cray-manifest`, which reads a json file that describes a set of package DAGs. The parsed results are stored directly in the database. A user can see these installed specs with `spack find` (like any installed spec). The easiest way to use them right now as dependencies is to run `spack spec ... ^/hash-of-external-package`.
Changes include:
* `spack external read-cray-manifest --file <path/to/file>` will add all specs described in the file to Spack's installation DB and will also install described compilers to the compilers configuration (the expected format of the file is described in this PR as well including examples of the file)
* Database records now may include an "origin" (the command added in this PR registers the origin as "external-db"). In the future, it is assumed users may want to be able to treat installs registered with this command differently (e.g. they may want to uninstall all specs added with this command)
* Hash properties are now always preserved when copying specs if the source spec is concrete
* I don't think the hashes of installed-and-concrete specs should change and this was the easiest way to handle that
* also specs that are concrete preserve their `.normal` property when copied (external specs may mention compilers that are not registered, and without this change they would fail in `normalize` when calling `validate_or_raise`)
* it might be this should only be the case if the spec was installed
- [x] Improve testing
- [x] Specifically mark DB records added with this command (so that users can do something like "uninstall all packages added with `spack read-external-db`)
* This is now possible with `spack uninstall --all --origin=external-db` (this will remove all specs added from manifest files)
- [x] Strip variants that are listed in json entries but don't actually exist for the package

fixes#29446
The new setup_*_environment functions have been falling back
to calling the old functions and warn the user since #11115.
This commit removes the fallback behavior and any use of:
- setup_environment
- setup_dependent_environment
in the codebase
Change the internal representation of `Spec` to allow for multiple dependencies or
dependents stemming from the same package. This change permits to represent cases
which are frequent in cross compiled environments or to bootstrap compilers.
Modifications:
- [x] Substitute `DependencyMap` with `_EdgeMap`. The main differences are that the
latter does not support direct item assignment and can be modified only through its
API. It also provides a `select_by` method to query items.
- [x] Reworked a few public APIs of `Spec` to get list of dependencies or related edges.
- [x] Added unit tests to prevent regression on #11983 and prove the synthetic construction
of specs with multiple deps from the same package.
Since #22845 went in first, this PR reuses that format and thus it should not change hashes.
The same package may be present multiple times in the list of dependencies with different
associated specs (each with its own hash).
* environment.py: allow link:run
Some users want minimal views, excluding run-type dependencies, since
those type of dependencies are covered by rpaths and the symlinked
libraries in the view aren't used anyways.
With this change, an environment like this:
```
spack:
specs: ['py-flake8']
view:
default:
root: view
link: run
```
includes python packages and python, but no link type deps of python.
Speeds up comparison on `Version` by ~2.5x, e.g.
```python
In [1]: v = spack.version.Version('1.0.0'); w = spack.version.Version('1.0.2')
In [2]: %timeit v < w
1.47 µs ± 5.59 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
535 ns ± 1.75 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
```

The status displayed in the terminal title could be wrong when doing
distributed builds. For instance, doing `spack install glib` in two
different terminals could lead to the current package being reported as
`40/29` due to the way Spack handles retrying locks.
Work around this by keeping track of the package IDs that were already
encountered to avoid counting packages twice.

* cmd/checksum: prefer url matching url_from_version
This is a minimal change toward getting the right archive from places
like github. The heuristic is:
* if an archive url exists, take its version
* generate a url from the package with pkg.url_from_version
* if they match
* stop considering other URLs for this version
* otherwise, continue replacing the url for the version
I doubt this will always work, but it should address a variety of
versions of this bug. A good test right now is `spack checksum gh`,
which checksums macos binaries without this, and the correct source
packages with it.

prefer it and don't replace it

We can see what is in the bootstrap store with `spack find -b`, and you can clean it with `spack
clean -b`, but we can't do much else with it, and if there are bootstrap issues they can be hard to
debug.
We already have `spack --mock`, which allows you to swap in the mock packages from the command
line. This PR introduces `spack -b` / `spack --bootstrap`, which runs all of spack with
`ensure_bootstrap_configuration()` set. This means that you can run `spack -b find`, `spack -b
install`, `spack -b spec`, etc. to see what *would* happen with bootstrap configuration, to remove
specific bootstrap packages, etc. This will hopefully make developers' lives easier as they deal
with bootstrap packages.
This PR also uses a `nullcontext` context manager. `nullcontext` has been implemented in several
other places in Spack, and this PR consolidates them to `llnl.util.lang`, with a note that we can
delete the function if we ever reqyire a new enough Python.
- [x] introduce `spack --bootstrap` option
- [x] consolidated all `nullcontext` usages to `llnl.util.lang`
Some "concrete" versions on the command line, e.g. `qt@5` are really
meant to satisfy some actual concrete version from a package. We should
only assume the user is introducing a new, unknown version on the CLI
if we, well, don't know of any version that satisfies the user's
request. So, if we know about `5.11.1` and `5.11.3` and they ask for
`5.11.2`, we'd ask the solver to consider `5.11.2` as a solution. If
they just ask for `5`, though, `5.11.1` or `5.11.3` are fine solutions,
as they satisfy `@5`, so use them.

See https://github.com/spack/spack/issues/25353#issuecomment-1041868116
This commit changes the default behavior of
```
$ spack external find
```
from searching all the possible packages Spack knows about to
search only for the ones tagged as being a "build-tool".
It also introduces a `--all` option to restore the old behavior.
Prefer `sw_vers` to `platform.mac_ver`. In anaconda3 installation, for example, the latter reports 10.16 on Monterey -- I think this is affected by how and where the python instance was built.
Use MACOSX_DEPLOYMENT_TARGET if present to override the operating system choice.
It will be useful for metrics gathering and possibly debugging to
have this environment variable available in the runner pods that
do the actual rebuilds.
Since Spack does not install external packages, this commit skips them by
default when running stand-alone tests. The assumption is that such packages
have likely undergone an acceptance test process.
However, the tests can be run against installed externals using
```
% spack test run --externals ...
```
fixes#28260
Since we iterate over different variants from many packages, the variant
values may have types which are not comparable, which causes errors
at runtime. This is not a real issue though, since we don't need the facts
to be ordered. Thus, to avoid needless sorting, the sorted function has
been removed and a comment has been added to tip any developer that
might need to inspect these clauses for debugging to add back sorting
on the first two items only.
It's kind of difficult to add a test for this, since the error depends on
whether Python sorting algorithm ever needs to compare the third
value of a tuple being ordered.
* extensions: allow multiple "extends" directives
This will allow multiple extends directives in a package as long as only one of
them is selected as a dependency in the concrete spec.
* document the option to have multiple extends
Reuse previously was a very invasive change that required parameters to be added to all
the methods that called `concretize()` on a `Spec` object. With the addition of
concretizer configuration, we can use the config system to simplify this argument
passing and keep the code cleaner.
We decided that concretizer config options should be read at `Solver` instantiation
time, and if config changes between instnatiation of a particular solver and
`solve()` invocation, the `Solver` should use the settings from `__init__()`.
- [x] remove `reuse` keyword argument from most concretize functions
- [x] refactor usages to use `spack.config.override("concretizer:reuse", True)`
- [x] rework argument passing in `Solver` so that parameters are set from config
at instantiation time
`--reuse` was previously handled individually by each command that
needed it. We are growing more concretization options, and they'll
need their own section for commands that support them.
Now there are two concretization options:
* `--reuse`: Attempt to reuse packages from installs and buildcaches.
* `--fresh`: Opposite of reuse -- traditional spack install.
To handle thes, this PR adds a `ConfigSetAction` for `argparse`, so
that you can write argparse code like this:
```
subgroup.add_argument(
'--reuse', action=ConfigSetAction, dest="concretizer:reuse",
const=True, default=None,
help='reuse installed dependencies/buildcaches when possible'
)
```
With this, you don't need to add logic to pull the argument out and
handle it; the `ConfigSetAction` just does it for you. This can probably
be used to clean up some other commands later, as well.
Code that was previously passing `reuse=True` around everywhere has
been refactored to use config, and config is set from the CLI using
a new `add_concretizer_args()` function in `spack.cmd.common.arguments`.
- [x] Add `ConfigSetAction` to simplify concretizer config on the CLI
- [x] Refactor code so that it does not pass `reuse=True` to every function.
- [x] Refactor commands to use `add_concretizer_args()` and to pass
concretizer config using the config system.
Config scopes were different for `config` and `mutable_config`,
and `mutable_config` did not have a command line scope.
- [x] Fix by consolidating the creation logic for the two fixtures.
The concretizer is going to grow to have many more configuration,
and we really need some structured config for that.
* We have the `config:concretizer` option that chooses the solver,
but extending that is awkward (we'd need to replace a string with
a `dict`) and the solver choice will be deprecated eventually.
* We have the `concretization` option in environments, but it's
not a top-level config section -- it's just for environments,
and it also only admits a string right now.
To avoid overlapping with either of these and to allow the most
extensibility in the future, this adds a new `concretizer` config
section that can be used in and outside of environments. There
is only one option right now: `reuse`. This can expand to include
other options later.
Likely, we will soon deprecate `config:concretizer` and warn when
the user doesn't use `clingo`, and we will eventually (sometime later)
move the `together` / `separately` options from `concretization` into
the top-level `concretizer` section.
This commit just adds the new section and schema. Fully wiring it
up is TBD.
The solver has a lot of configuration associated with it. Rather
than adding arguments to everything, we should encapsulate that
in a class. This is the start of that work; it replaces `solve()`
and its kwargs with a class and properties.

Many packages implement logic at the class level to handle complex dependencies and
conflicts. Others have started using `with when("@1.0"):` blocks since we added that
capability. The loops and other control logic can cause some pure directive logic not to
be removed by our package hashing logic -- and in many cases that's a lot of code that
will cause unnecessary rebuilds.
This commit changes the unparser so that it will descend into these blocks. Specifically:
1. Descend into loops, if statements, and with blocks at the class level.
2. Don't look inside function definitions (in or outside a class).
3. Don't look at nested class definitions (they don't have directives)
4. Add logic to *remove* empty loops/with blocks/if statements if all directives
in them were removed.
This allows our package hash to ignore a lot of pure metadata that it was not ignoring
before, and makes it less sensitive.
In addition, we add `maintainers` and `tags` to the list of metadata attributes that
Spack should remove from packages when constructing canonoical source for a package
hash.
- [x] Make unparser handle if/for/while/with at class level.
- [x] Add tests for control logic removal.
- [x] Add a test to ensure that all packages are not only unparseable, but also
that their canonical source is still compilable. This is a test for
our control logic removal.
- [x] Add another unparse test package that has complex logic.
These are the unit tests from astunparse, converted to pytest, with a few backports from
upstream cpython. These should hopefully keep `unparser.py` well covered as we change it.
We can't tell `print(a, b, c)` and `print((a, b, c))` apart -- both of these expressions
generate different ASTs in Python 2 and Python 3. However, we can decide that we don't
care. This commit treats both of them the same when `py_ver_consistent` is set with
`unparse()`.
This means that the package hash won't notice changes from printing a tuple to printing
multiple values, but we don't care, because this is extremely unlikely to affect the build.
More than likely this is just an error message for the user of the package.
- [x] treat `print(a, b, c)` and `print((a, b, c))` the same in py2 and py3
- [x] add another package parsing test -- legion -- that exercises this feature
To make it easier to see how package hashes change and how they are computed, add two
commands:
* `spack pkg source <spec>`: dumps source code for a package to the terminal
* `spack pkg source --canonical <spec>`: dumps canonicalized source code for a
package to the terminal. It strips comments, directives, and known-unused
multimethods from the package. It is used to generate package hashes.
* `spack pkg hash <spec>`: This gives the package hash for a particular spec.
It is generated from the canonical source code for the spec.
- [x] `add spack pkg source` and `spack pkg hash`
- [x] add tests
- [x] fix bug in multimethod resolution with boolean `@when` values
Co-authored-by: Greg Becker <becker33@llnl.gov>
We are planning to switch to using full hashes for Spack specs, which means that the
package hash will be included in the deployment descriptor. This means we need a more
robust package hash than simply dumping the `repr` of the AST.
The AST repr that we previously used for package content is unreliable because it can
vary between python versions (Python's AST actually changes fairly frequently).
- [x] change `package_hash`, `package_ast`, and `canonical_source` to accept a string for
alternate source instead of a filename.
- [x] consolidate package hash tests in `test/util/package_hash.py`.
- [x] remove old `package_content` method.
- [x] make `package_hash` do what `canonical_source_hash` was doing before.
- [x] modify `content_hash` in `package.py` to use the new `package_hash` function.

Our package hash is supposed to be consistent from python version to python version.
Test this by adding some known unparse inputs and ensuring that they always have the
same canonical hash. This test relies on the fact that we run Spack's unit tests
across many python versions. We can't compute for several python versions within the
same test run so we precompute the hashes and check them in CI.
Package hashing was not properly handling multimethods. In particular, it was removing
any functions that had decorators from the output, so we'd miss things like
`@run_after("install")`, etc.
There were also problems with handling multiple `@when`'s in a single file, and with
handling `@when` functions that *had* to be evaluated dynamically.
- [x] Rework static `@when` resolution for package hash
- [x] Ensure that functions with decorators are not removed from output
- [x] Add tests for many different @when scenarios (multiple @when's,
combining with other decorators, default/no default, etc.)

Previously we used `directives.__all__` to get directive names, but it wasn't
quite right -- it included `DirectiveMeta`, etc. It's not wrong, but it's also
not the clearest way to do this.
- [x] Refactor `@directive` to track names in `directive_names` global
- [x] Rename `_directive_names` to `_directive_dict_names` in `DirectiveMeta`
- [x] Add a test for `RemoveDirectives`

Some packages use top-level unassigned strings instead of comments, either just after a
docstring on in the body somewhere else. Ignore those strings becasue they have no
effect on package behavior.
- [x] adjust RemoveDocstrings to remove all free-standing strings.
- [x] move tests for util/package_hash.py to test/util/package_hash.py

Python 2 and 3 represent string literals differently in the AST. Python 2 requires '\x'
literals, and Python 3 source is always unicode, and allows unicode to be written
directly. These also unparse differently by default.
- [x] modify unparser to write both out the way `repr` would in Python 2 when
`py_ver_consistent` is provided.
Backport operator precedence algorithm from here:
397b96f6d7
This eliminates unnecessary parentheses from our unparsed output and makes Spack's unparser
consistent with the one in upstream Python 3.9+, with one exception.
Our parser normalizes argument order when `py_ver_consistent` is set, so that star arguments
in function calls come last. We have to do this because Python 2's AST doesn't have information
about their actual order.
If we ever support only Python 3.9 and higher, we can easily switch over to `ast.unparse`, as
the unparsing is consistent except for this detail (modulo future changes to `ast.unparse`)
Previously, there were differences in the unparsed code for Python 2.7 and for 3.5-3.10.
This makes unparsed code the same across these Python versions by:
1. Ensuring there are no spaces between unary operators and
their operands.
2. Ensuring that *args and **kwargs are always the last arguments,
regardless of the python version.
3. Always unparsing print as a function.
4. Not putting an extra comma after Python 2 class definitions.
Without these changes, the same source can generate different code for different
Python versions, depending on subtle AST differences.
One place where single source will generate an inconsistent AST is with
multi-argument print statements, e.g.:
```
print("foo", "bar", "baz")
```
In Python 2, this prints a tuple; in Python 3, it is the print function with
multiple arguments. Use `from __future__ import print_function` to avoid
this inconsistency.
Add `astunparse` as `spack_astunparse`. This library unparses Python ASTs and we're
adding it under our own name so that we can make modifications to it.
Ultimately this will be used to make `package_hash` consistent across Python versions.

* locks: allow locks to work under high contention
This is a bug found by Harshitha Menon.
The `lock=None` line shouldn't be a release but should be
```
return (lock_type, None)
```
to inform the caller it couldn't get the lock type requested without
disturbing the existing lock object in the database. There were also a
couple of bugs due to taking write locks at the beginning without any
checking or release, and not releasing read locks before requeueing.
This version no longer gives me read upgrade to write errors, even
running 200 instances on one box.
* Change lock in check_deps_status to read, release if not installed,
not sure why this was ever write, but read definitely is more
appropriate here, and the read lock is only held out of the scope if
the package is installed.
* Release read lock before requeueing to reduce chance of livelock, the
timeout that caused the original issue now happens in roughly 3 of 200
workers instead of 199 on average.

The latest version of `jsonschema` fails if we're not specific about which schema draft
specification we're using. Update all of them to use the latest one (draft-07).
Our `jsonschema` external won't support Python 3.10, so we need to upgrade it.
It currently generates this warning:
lib/spack/external/jsonschema/compat.py:6: DeprecationWarning: Using or importing the ABCs
from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and
in 3.10 it will stop working
This upgrades `jsonschema` to 3.2.0, the latest version with support for Python 2.7. The next
version after this (4.0.0) drops support for 2.7 and 3.6, so we'll have to wait to upgrade to it.
Dependencies have been added in prior commits.
spack monitor now requires authentication as each build must be associated

This PR also slightly changes the behavior in ci_rebuild().
We now still attempt to submit `spack install` results to CDash
even if the initial registration failed due to connection issues.
This commit follows in the spirit of #24299. We do not want `spack install`
to exit with a non-zero status when something goes wrong while attempting to
report results to CDash.
This PR is meant to move code with "business logic" from `spack.cmd.buildcache` to appropriate core modules[^1].
Modifications:
- [x] Add `spack.binary_distribution.push` to create a binary package from a spec and push it to a mirror
- [x] Add `spack.binary_distribution.install_root_node` to install only the root node of a concrete spec from a buildcache (may check the sha256 sum if it is passed in as input)
- [x] Add `spack.binary_distribution.install_single_spec` to install a single concrete spec from a buildcache
- [x] Add `spack.binary_distribution.download_single_spec` to download a single concrete spec from a buildcache to a local destination
- [x] Add `Spec.from_specfile` that construct a spec given the path of a JSON or YAML spec file
- [x] Removed logic from `spack.cmd.buildcache`
- [x] Removed calls to `spack.cmd.buildcache` in `spack.bootstrap`
- [x] Deprecate `spack buildcache copy` with a message that says it will be removed in v0.19.0
[^1]: The rationale is that commands should be lightweight wrappers of the core API, since that helps with both testing and scripting (easier mocking and no need to invoke `SpackCommand`s in a script).
After this PR an error in a single package while detecting
external software won't abort the entire procedure.
The error is reported to screen as a warning.
Remove a try/catch for an error with no handling. If the affected
code doesn't execute successfully, then the associated variable
is undefined and another (more-obscure) error occurs shortly after.
Remove a custom bootstrapping procedure to
use spack.bootstrap instead
Modifications:
* Reference count the bootstrap context manager
* Avoid SpackCommand to make the bootstrapping
procedure more transparent
* Put back requirement on patchelf being in PATH for unit tests
* Add an e2e test to check bootstrapping patchelf
I think this test should be removed, but when it stays, it should at
least follow the symlink, cause it fails for me if I let spack build
patchelf and have a symlink in a view.
Modifications:
- [x] Removed `centos:6` unit test, adjusted vermin checks
- [x] Removed backport of `collections.OrderedDict`
- [x] Removed backport of `functools.total_ordering`
- [x] Removed Python 2.6 specific skip markers in unit tests
- [x] Fixed a few minor Python 2.6 related TODOs in code

* Make CUDA and ROCm architecture conditional
fixes#14337
The variant to specify which architecture to use
for CUDA and ROCm are now conditional on +cuda and
+rocm respectively.
* cp2k: make all CUDA related variants conditional on +cuda
* Add connection specification to mirror creation
This allows each mirror to contain information about the credentials
used to access it.
Update command and tests based on comments
Switch to only "long form" flags for the s3 connection information.
Use the "any" function instead of checking for an empty list when looking
for s3 connection information.
Split test to use the access token separately from the access id and key.
Use long flag form in test.
Add endpoint_url to available S3 options.
Extend the special parameters for an S3 mirror to accept the
endpoint_url parameter.
Add a test.
* Add connection information per URL not per mirror
Expand the mirror-based connection information to be per-URL.
This will allow a user to specify different S3 connection information
for both the fetch and the push URLs.
Add a parameter for "profile", another way of storing the id/secret pair.
* Switch from "access_profile" to "profile"
Remove the "get_executable" function from the
spack.bootstrap module. Now "flake8", "isort",
"mypy" and "black" will use the same
bootstrapping method as GnuPG.
Currently Spack vendors `pytest` at a version which is three major
versions behind the latest (3.2.5 vs. 6.2.4). We do that since v3.2.5
is the latest version supporting Python 2.6. Remaining so much
behind the currently supported versions though might introduce
some incompatibilities and is surely a technical debt.
This PR modifies Spack to:
- Use the vendored `pytest@3.2.5` only as a fallback solution,
if the Python interpreter used for Spack doesn't provide a newer one
- Be able to parse `pytest --collect-only` in all the different output
formats from v3.2.5 to v6.2.4 and use it consistently for `spack unit-test --list-*`
- Updating the unit tests in Github Actions to use a more recent `pytest` version
This type of error is skipped:
make[1]: *** [Makefile:222: /tmp/user/spack-stage/.../spack-src/usr/lib/julia/libopenblas64_.so.so] Error 1
but it's useful to have it, especially when a package sets a variable
incorrectly in makefiles
Intel mpi comes with an installation of libfabric (which it needs as a
dependency). It can use other implementations of libfabric at runtime
though, so if you install a package that depends on `mpi` and
`libfabric`, you can specify `intel-mpi+external-libfabric` and ensure
that the Spack-built instance is used (both by `intel-mpi` and the
root).
Apply analogous change to intel-oneapi-mpi.
When running `spack install --log-format junit|cdash ...`, install
errors were ignored. This made spack continue building dependents of
failed install, ignoring `--fail-fast`, and exit 0 at the end.

fixes#27237
The mechanism to reuse concrete specs relies on imposing
the set of constraints stemming from the concrete spec
being reused.
We also need to prevent that other constraints get added
to this set.
See #25249 and https://github.com/spack/spack/pull/27159#issuecomment-958163679.
This adds `spack load --list` as an alias for `spack find --loaded`. The new command is
not as powerful as `spack find --loaded`, as you can't combine it with all the queries or
formats that `spack find` provides. However, it is more intuitively located in the command
structure in that it appears in the output of `spack load --help`.
The idea here is that people can use `spack load --list` for simple stuff but fall back to
`spack find --loaded` if they need more.
- add help to `spack load --list` that references `spack find`
- factor some parts of `spack find` out to be called from `spack load`
- add shell tests
- update docs

Reformulate variant rules so that we minimize both
1. The number of non-default values being used
2. The number of default values not-being used
This is crucial for MV variants where we may have
more than one default value
In our tests, we use concrete specs generated from mock packages,
which *only* occur as inputs to the solver. This fixes two problems:
1. We weren't previously adding facts to encode the necessary
`depends_on()` relationships, and specs were unsatisfiable on
reachability.
2. Our hash lookup for reconstructing the DAG does not
consider that a hash may have come from the inputs.
Concrete specs that are already installed or that come from a buildcache
may have compilers and variant settings that we do not recognize, but that
shouldn't prevent reuse (at least not until we have a more detailed compiler
model).
- [x] make sure compiler and variant consistency rules only apply to
built specs
- [x] don't validate concrete specs on input, either -- they're concrete
and we shouldn't apply today's rules to yesterday's build
In switching to hash facts for concrete specs, we lost the transitive facts
from dependencies. This was fine for solves, because they were implied by
the imposed constraints from every hash. However, for `spack diff`, we want
to see what the hashes mean, so we need another mode for `spec_clauses()` to
show that.
This adds a `expand_hashes` argument to `spec_clauses()` that allows us to
output *both* the hashes and their implications on dependencies. We use
this mode in `spack diff`.
- [x] Get rid of forgotten maximize directive.
- [x] Simplify variant handling
- [x] Fix bug in treatment of defaults on externals (don't count
non-default variants on externals against them)
Variants in concrete specs are "always" correct -- or at least we assume
them to be b/c they were concretized before. Their variants need not match
the current version of the package.
Multi-valued variants previously maximized default values to handle
cases where the default contained two values, e.g.:
variant("foo", default="bar,baz")
This is because previously we were minimizing non-default values, and
`foo=bar`, `foo=baz`, and `foo=bar,baz` all had the same score, as
none of them had any "non-default" values.
This commit changes the approach and considers a non-default value
to be either a value set to something not default *or* the absence
of a default value from the set value. This allows multi- and
single-valued variants to be handled the same way, with the same
minimization criterion. It alse means that the "best" value for every
optimization criterion is now zero, which allows us to make useful
assumptions about the optimization criteria.
Minimizing builds is tricky. We want a minimizing criterion because
we want to reuse the avaialble installs, but we also want things that
have to be built to stick to *default preferences* from the package
and from the user. We therefore treat built specs differently and
apply a different set of optimization criteria to them. Spack's *first*
priority is to reuse what it can, but if it builds something, the built
specs will respect defaults and preferences.
This is implemented by bumping the priority of optimization criteria
for built specs -- so that they take precedence over the otherwise
topmost-priority criterion to reuse what is installed.
The scheme relies on all of our optimization criteria being minimizations.
That is, we need the case where all specs are reused to be better than
any built spec could be. Basically, if nothing is built, all the build
criteria are zero (the best possible) and the number of built packages
dominates. If something *has* to be built, it must be strictly worse
than full reuse, because:
1. it increases the number of built specs
2. it must have either zero or some positive number for all criteria
Our optimziation criteria effectively sum into two buckets at once to
accomplish this. We use a `build_priority()` number to shift the
priority of optimization criteria for built specs higher.
The constraints in the `spack diff` test were very specific and assumed
a lot about the structure of what was being diffed. Relax them a bit to
make them more resilient to changes.
Make the first minimization conditional on whether `--reuse` is enabled in the solve.
If `--reuse` is not enabled, there will be nothing in the set to minimize and the
objective function (for this criterion) will be 0 for every answer set.
Many of the integrity constraints in the concretizer are there to restrict how solves are done, but
they ignore that past solves may have had different initial conditions. For example, for things
we're building, we want the allowed variants to be restricted to those currently in Spack packages,
but if we are reusing a concrete spec, we need to be flexible about names that may have existed in
old packages.
Similarly, restrictions around compatibility of OS's, compiler versions, compiler OS support, etc.
are really only about what is supported by the *current* set of compilers/build tools known to
Spack, not about what we may get from concrete specs.
- [x] restrict certain integrity constraints to only apply to packages that we need to build, and
omit concrete specs from consideration.
The OS logic in the concretizer is still the way it was in the first version.
Defaults are implemented in a fairly inflexible way using straight logic. Most
of the other sections have been reworked to leave these kinds of decisions to
optimization. This commit does that for OS's as well.
As with targets, we optimize for target matches. We also try to optimize for
OS matches between nodes. Additionally, this commit adds the notion of
"OS compatibility" where we allow for builds to depend on binaries for certain
other OS's. e.g, for macos, a bigsur build can depend on an already installed
(concrete) catalina build. One cool thing about this is that we can declare
additional compatible OS's later, e.g. CentOS and RHEL.
If we don't rename Spack will fail with:
```
ImportError: cannot bootstrap the "clingo" Python module from spec "clingo-bootstrap@spack+python %gcc target=x86_64" due to the following failures:
'spack-install' raised ValueError: Invalid config scope: 'bootstrap'. Must be one of odict_keys(['_builtin', 'defaults', 'defaults/cray', 'bootstrap/cray', 'disable_modules', 'overrides-0'])
Please run `spack -d spec zlib` for more verbose error messages
```
in case bootstrapping from binaries fails and we are
falling back to bootstrapping from sources.
A common question from users has been how to model variants
that are new in new versions of a package, or variants that are
dependent on other variants. Our stock answer so far has been
an unsatisfying combination of "just have it do nothing in the old
version" and "tell Spack it conflicts".
This PR enables conditional variants, on any spec condition. The
syntax is straightforward, and matches that of previous features.
* GnuPG: allow bootstrapping from buildcache and sources
* Add a test to bootstrap GnuPG from binaries
* Disable bootstrapping in tests
* Add e2e test to bootstrap GnuPG from sources on Ubuntu
* Add e2e test to bootstrap GnuPG on macOS
This PR adds error message sentinels to the clingo solve, attached to each of the rules that could fail a solve. The unsat core is then restricted to these messages, which makes the minimization problem tractable. Errors that can only be generated by a bug in the logic program or generating code are prefaced with "Internal error" to make clear to users that something has gone wrong on the Spack side of things.
* minimize unsat cores manually
* only errors messages are choices/assumptions for performance
* pre-check for unreachable nodes
* update tests for new error message
* make clingo concretization errors show up in cdash reports fully
* clingo: make import of clingo.ast parsing routines robust to clingo version
Older `clingo` has `parse_string`; newer `clingo` has `parse_files`. Make the
code work wtih both.
* make AST access functions backward-compatible with clingo 5.4.0
Clingo AST API has changed since 5.4.0; make some functions to help us
handle both versions of the AST.

After #26608 I got a report about missing rpaths when building a
downstream package independently using a spack-installed toolchain
(@tmdelellis). This occurred because the spack-installed libraries were
being linked into the downstream app, but the rpaths were not being
manually added. Prior to #26608 autotools-installed libs would retain
their hard-coded path and would thus propagate their link information
into the downstream library on mac.
We could solve this problem *if* the mac linker (ld) respected
`LD_RUN_PATH` like it does on GNU systems, i.e. adding `rpath` entries
to each item in the environment variable. However on mac we would have
to manually add rpaths either using spack's compiler wrapper scripts or
manually (e.g. using `CMAKE_BUILD_RPATH` and pointing to the libraries of
all the autotools-installed spack libraries).
The easier and safer thing to do for now is to simply stop changing the
dylib IDs.
The `--generic` argument allows printing the best generic target for the
current machine. This can be quite handy when wanting to find the
generic architecture to use when building a shared software stack for
multiple machines.
This PR adds a "spack tags" command to output package tags or
(available) packages with those tags. It also ensures each package
is listed in the tag cache ONLY ONCE per tag.

If you don't format `spack.yaml` correctly, `spack config edit` still fails and
you have to edit your `spack.yaml` manually.
- [x] Add some code to `_main()` to defer `ConfigFormatError` when loading the
environment, until we know what command is being run.
- [x] Make `spack config edit` use `SPACK_ENV` instead of the config scope
object to find `spack.yaml`, so it can work even if the environment is bad.

`spack config get <section>` was erroneously returning just the `spack.yaml`
for the environment.
It should return the combined configuration for that section (including
anything from `spack.yaml`), even in an environment.
- [x] reorder conditions in `cmd/config.py` to fix
`spack --debug config edit` was not working properly -- it would not do show a
stack trace for configuration errors.

`main()` has grown, and in some cases code that can generate errors has gotten
outside the top-level try/catch in there. This means that simple errors like
config issues give you large stack traces, which shouldn't happen without
`--debug`.
- [x] Split `main()` into `main()` for the top-level error handling and
`_main()` with all logic.
There were some loose ends left in ##26735 that cause errors when
using `SPACK_DISABLE_LOCAL_CONFIG`.
- [x] Fix hard-coded `~/.spack` references in `install_test.py` and `monitor.py`
Also, if `SPACK_DISABLE_LOCAL_CONFIG` is used, there is the issue that
`$user_config_path`, when used in configuration files, makes no sense,
because there is no user config scope.
Since we already have `$user_cache_path` in configuration files, and since there
really shouldn't be *any* data stored in a configuration scope (which is what
you'd configure in `config.yaml`/`bootstrap.yaml`/etc., this just removes
`$user_config_path`.
There will *always* be a `$user_cache_path`, as Spack needs to write files, but
we shouldn't rely on the existence of a particular configuration scope in the
Spack code, as scopes are configurable, both in number and location.
- [x] Remove `$user_config_path` substitution.
- [x] Fix reference to `$user_config_path` in `etc/spack/deaults/bootstrap.yaml`
to refer to `$user_cache_path`, which is where it was intended to be.
* Deactivate previous env before activating new one
Currently on develop you can run `spack env activate` multiple times to switch
between environments, but they leave traces, even though Spack only supports
one active environment at a time.
Currently:
```console
$ spack env create a
$ spack env create b
$ spack env activate -p a
[a] $ spack env activate -p b
[b] [a] $ spack env activate -p b
[a] [b] [a] $ spack env activate -p a
[a] [b] [c] $ echo $MANPATH | tr ":" "\n"
/path/to/environments/a/.spack-env/view/share/man
/path/to/environments/a/.spack-env/view/man
/path/to/environments/b/.spack-env/view/share/man
/path/to/environments/b/.spack-env/view/man
```
This PR fixes that:
```console
$ spack env activate -p a
[a] $ spack env activate -p b
[b] $ spack env activate -p a
[a] $ echo $MANPATH | tr ":" "\n"
/path/to/environments/a/.spack-env/view/share/man
/path/to/environments/a/.spack-env/view/man
```
* Drastically improve YamlFilesystemView file removal via batching
The `remove_file` routine has to check if the file is owned by multiple packages, so it doesn't
remove necessary files. This is done by the `get_all_specs` routine, which walks the entire
package tree. With large numbers of packages on shared file systems, this can take seconds
per file tree traversal, which adds up extremely quickly. For example, a single deactivate
of a largish python package in our software stack on GPFS took approximately 40 minutes.
This patch simply replaces `remove_file` with a batch `remove_files` routine. This routine
removes a list of files rather than a single file, requiring only one traversal per batch. In
practice this means a package can be removed in seconds time, rather than potentially hours,
essentially a ~100x speedup (ignoring initial deactivation logic, which takes about 3 minutes
in our test setup).
* Fix sbang hook for non-writable files
PR #26793 seems to have broken the sbang hook for files with missing
write permissions. Installing perl now breaks with the following error:
```
==> [2021-10-28-12:09:26.832759] Error: PermissionError: [Errno 13] Permission denied: '$SPACK/opt/spack/linux-fedora34-zen2/gcc-11.2.1/perl-5.34.0-afuweplnhphcojcowsc2mb5ngncmczk4/bin/cpanm'
```
Temporarily add write permissions to the original file so it can be
overwritten with the patched one.
And test that file permissions are preserved in sbang even for non-writable files

When relocating a binary distribution, Spack only checks files to see
if they are a link that needs to be relocated. Directories can be
such links as well, however, and need to undergo the same checks
and potential relocation.
`spack list` tests are not using mock packages for some reason, and many
are marked as potentially slow. This isn't really necessary; we don't need
6,000 packages to test the command.
- [x] update tests to use `mock_packages` fixture
- [x] remove `maybeslow` annotations
Currently Spack reads full files containing shebangs to memory as
strings, meaning Spack would have to guess their encoding. Currently
Spack has a fixed guess of UTF-8.
This is unnecessary, since e.g. the Linux kernel does not assume an
encoding on paths at all, it's just bytes and some delimiters on the
byte level.
This commit does the following:
1. Shebangs are treated as bytes, so that e.g. latin1 encoded files do
not throw UnicodeEncoding errors, and adds a test for this.
2. No more bytes than necessary are read to memory, we only have to read
until the first newline, and from there on we an copy the file byte by
bytes instead of decoding and re-encoding text.
3. We cap the number of bytes read to 4096, if no newline is found
before that, we don't attempt to patch it.
4. Add support for luajit too.
This should make Spack both more efficient and usable for non-UTF8
files.
Spack's `system` and `user` scopes provide ways for administrators and
users to set global defaults for all Spack instances, but for use cases
where one wants a clean Spack installation, these scopes can be undesirable.
For example, users may want to opt out of global system configuration, or
they may want to ignore their own home directory settings when running in
a continuous integration environment.
Spack also, by default, keeps various caches and user data in `~/.spack`,
but users may want to override these locations.
Spack provides three environment variables that allow you to override or
opt out of configuration locations:
* `SPACK_USER_CONFIG_PATH`: Override the path to use for the
`user` (`~/.spack`) scope.
* `SPACK_SYSTEM_CONFIG_PATH`: Override the path to use for the
`system` (`/etc/spack`) scope.
* `SPACK_DISABLE_LOCAL_CONFIG`: set this environment variable to completely
disable *both* the system and user configuration directories. Spack will
only consider its own defaults and `site` configuration locations.
And one that allows you to move the default cache location:
* `SPACK_USER_CACHE_PATH`: Override the default path to use for user data
(misc_cache, tests, reports, etc.)
With these settings, if you want to isolate Spack in a CI environment, you can do this:
export SPACK_DISABLE_LOCAL_CONFIG=true
export SPACK_USER_CACHE_PATH=/tmp/spack
This is a stop-gap approach until we have figured out how to deal with
the system and user config scopes more generally, as there are plans to
potentially / eventually get rid of them.
**User config**
Spack is a bit of a pain when you have:
- a shared $HOME folder across different systems.
- multiple Spack versions on the same system.
**System config**
- On shared systems with a versioned programming environment / toolkit,
system administrators want to provide config for each version (e.g.
21.09, 21.10) of the programming environment, and the user Spack
instance should be able to pick this up without a steep learning
curve.
- On shared systems the user should be able to opt out of the
hard-coded config scope in /etc/spack, since it may be incompatible
with their particular instance. Currently Spack can only opt out of all
config scopes through overrides with `"config:":`, `"packages:":`, but that
also drops the defaults config, which would have to be repeated, which
is undesirable, especially the lengthy packages.yaml.
An example use case is: having config in this folder:
```
/path/to/programming/environment/{version}/{compilers,packages}.yaml
```
and have `module load spack-system-config` set the variable
```
SPACK_SYSTEM_CONFIG_PATH=/path/to/programming/environment/{version}
```
where the user no longer has to worry about what `{version}` they are
on.
**Continuous integration**
Finally, there is the use case of continuous integration, which may
clone an arbitrary Spack version, which optimally should not pick up
system or user config from the previous run (like may happen in
classical bare metal non-containerized filesystem side effect ridden
jenkins pipelines). In fact this is very similar to how spack itself
tries to avoid picking up system dependencies during builds...
**But environments solve this?**
- You could do `include`s in environment files to get similar behavior
to the spack_system_config_path example, but environments require you
to:
1) require paths to individual config files, not directories.
2) fail if the listed config file does not exist
- They allow you to override config scopes, but this is generally too
rigurous, as it requires you to repeat the default config, in
particular packages.yaml, and just defies the point of layered config.

Any spec satisfying a default will be symlinked to `default`
If multiple specs have modulefiles in the same directory and satisfy
configured module defaults, then whichever was written last will be
default.
This PR permits to specify the `url` and `ref` of the Spack instance used in a container recipe simply by expanding the YAML schema as outlined in #20442:
```yaml
container:
images:
os: amazonlinux:2
spack:
ref: develop
resolve_sha: true
```
The `resolve_sha` option, if true, verifies the `ref` by cloning the Spack repository in a temporary directory and transforming any tag or branch name to a commit sha. When this new ability is leveraged an additional "bootstrap" stage is added, which builds an image with Spack setup and ready to install software. The Spack repository to be used can be customized with the `url` keyword under `spack`.
Modifications:
- [x] Permit to pin the version of Spack, either by branch or tag or sha
- [x] Added a few new OSes (centos:8, amazonlinux:2, ubuntu:20.04, alpine:3, cuda:11.2.1)
- [x] Permit to print the bootstrap image as a standalone
- [x] Add documentation on the new part of the schema
- [x] Add unit tests for different use cases
1. Currently it prints not just the spec name, but the dependencies +
their variants + their compilers + their architectures + ...
2. It's clear from the context what spec the message applies to, so,
let's not print the spec at all.
These three rules in `concretize.lp` are overly complex:
```prolog
:- not provider(Package, Virtual),
provides_virtual(Package, Virtual),
virtual_node(Virtual).
```
```prolog
:- provides_virtual(Package, V1), provides_virtual(Package, V2), V1 != V2,
provider(Package, V1), not provider(Package, V2),
virtual_node(V1), virtual_node(V2).
```
```prolog
provider(Package, Virtual) :- root(Package), provides_virtual(Package, Virtual).
```
and they can be simplified to just:
```prolog
provider(Package, Virtual) :- node(Package), provides_virtual(Package, Virtual).
```
- [x] simplify virtual rules to just one implication
- [x] rename `provides_virtual` to `virtual_condition_holds`
fixes#26866
This semantics fits with the way Spack currently treats providers of
virtual dependencies. It needs to be revisited when #15569 is reworked
with a new syntax.
* py-vermin: add latest version 1.3.1
* Exclude line from Vermin since version is already being checked for
Vermin 1.3.1 finds that `encoding` kwarg of builtin `open()` requires Python 3+.
The OS should only interpret shebangs, if a file is executable.
Thus, there should be no need to modify files where no execute bit is set.
This solves issues that are e.g. encountered while packaging software as
COVISE (https://github.com/hlrs-vis/covise), which includes example data
in Tecplot format. The sbang post-install hook is applied to every installed
file that starts with the two characters #!, but this fails on the binary Tecplot
files, as they happen to start with #!TDV. Decoding them with UTF-8 fails
and an exception is thrown during post_install.

This commit contains changes to support Google Cloud Storage
buckets as mirrors, meant for hosting Spack build-caches. This
feature is beneficial for folks that are running infrastructure on
Google Cloud Platform. On public cloud systems, resources are
ephemeral and in many cases, installing compilers, MPI flavors,
and user packages from scratch takes up considerable time.
Giving users the ability to host a Spack mirror that can store build
caches in GCS buckets offers a clean solution for reducing
application rebuilds for Google Cloud infrastructure.

1. Don't use 16 digits of precision for the seconds, round to 2 digits after the comma
2. Don't print if we don't concretize (i.e. `spack concretize` without `-f` doesn't have to tell me it did nothing in `0.00` seconds)
* Speed-up environment concretization with a process pool
We can exploit the fact that the environment is concretized
separately and use a pool of processes to concretize it.
* Add module spack.util.parallel
Module includes `pool` and `parallel_map` abstractions,
along with implementation details for both.
* Add a new hash type to pass specs across processes
* Add tty msg with concretization time
We use POSIX `patch` to apply patches to files when building, but
`patch` by default prompts the user when it looks like a patch
has already been applied. This means that:
1. If a patch lands in upstream and we don't disable it
in a package, the build will start failing.
2. `spack develop` builds (which keep the stage around) will
fail the second time you try to use them.
To avoid that, we can run `patch` with `-N` (also called
`--forward`, but the long option is not in POSIX). `-N` causes
`patch` to just ignore patches that have already been applied.
This *almost* makes `patch` idempotent, except that it returns 1
when it detects already applied patches with `-N`, so we have to
look at the output of the command to see if it's safe to ignore
the error.
- [x] Remove non-POSIX `-s` option from `patch` call
- [x] Add `-N` option to `patch`
- [x] Ignore error status when `patch` returns 1 due to `-N`
- [x] Add tests for applying a patch twice and applying a bad patch
- [x] Tweak `spack.util.executable` so that it saves the error that
*would have been* raised with `fail_on_error=True`. This lets
us easily re-raise it.

Currently Spack keeps track of the origin in the code of any
modification to the environment variables. This is very slow
and enabled unconditionally even in code paths where the
origin of the modification is never queried.
The only place where we inspect the origins of environment
modifications is before we start a build, If there's an override
of the type `e.set(...)` after incremental changes like
`e.append_path(..)`, which is a "suspicious" change.
This is very rare though.
If an override like this ever happens, it might mean a package is
broken. If that leads to build errors, we can just ask the user to run
`spack -d install ...` and check the warnings issued by Spack to find
the origins of the problem.
It can be frustrating to successfully run `spack test run --alias <name>` only to find you cannot get the results because you already use `<name>` in some previous stand-alone test execution. This PR prevents that from happening.
Using the Spec.constrain method doesn't work since it might
trigger a repository lookup which could break our directives
and triggers a circular import error.
To fix that we introduce a function to merge abstract anonymous
specs, based only on package names, which does not perform any
lookup in the repository.
The buildcache is now extracted in a temporary folder within the current store,
moved to its final place and relocated.
"spack clean -s" has been extended to also clean the temporary extraction directory.
Add hardlinks with absolute paths for libraries in the corge, garply and quux packages
to detect incorrect handling of hardlinks in tests.
The `find` command was missing for the examples forcing colorized output. Without this (or another suitable) command, spack produces output that is not using any color. Thus, without the `find` command one does not see any difference between forced colorized and non-colorized output.
when deployed on kubernetes, the server sends back permanent redirect responses.
This is elegantly handled by the requests library, but not urllib that we have
to use here, so I have to manually handle it by parsing the exception to
get the Location header, and then retrying the request there.

The ASP-based solver maximizes the number of values in multi-valued
variants (if other higher order constraints are met), to avoid cases
where only a subset of the values that have been specified on the
command line or imposed by another constraint are selected.
Here we swap the priority of this optimization target with the
selection of the default providers, to avoid unexpected results
like the one in #26598
Seems like https://bugs.python.org/issue29699 is relevant. Better to
just ignore errors when removing them tmpdir. The OS will remove it
anyways.
Errors are happening randomly from tests that are using this fixture.
TL;DR: there are matching groups trying to match 1 or more occurrences of
something. We don't use the matching group. Therefore it's sufficient to test
for 1 occurrence. This reduce quadratic complexity to linear time.
---
When parsing logs of an mpich build, I'm getting a 4 minute (!!) wait
with 16 threads for regexes to run:
```
In [1]: %time p.parse("mpich.log")
Wall time: 4min 14s
```
That's really unacceptably slow...
After some digging, it seems a few regexes tend to have `O(n^2)` scaling
where `n` is the string / log line length. I don't think they *necessarily*
should scale like that, but it seems that way. The common pattern is this
```
([^:]+): error
```
which matches `: error` literally, and then one or more non-colons before that. So
for a log line like this:
```
abcdefghijklmnopqrstuvwxyz: error etc etc
```
Any of these are potential group matches when using `search` in Python:
```
abcdefghijklmnopqrstuvwxyz
bcdefghijklmnopqrstuvwxyz
cdefghijklmnopqrstuvwxyz
⋮
yz
z
```
but clearly the capture group should return the longest match.
My hypothesis is that Python has a very bad implementation of `search`
that somehow considers all of these, even though it can be implemented
in linear time by scanning for `: error` first, and then greedily expanding
the longest possible `[^:]+` match to the left. If Python indeed considers
all possible matches, then with `n` matches of length `1 .. n` you
see the `O(n^2)` slowness (i verified this by replacing + with {1,k}
and doubling `k`, it doubles the execution time indeed).
This PR fixes this by removing the `+`, so effectively changing the
O(n^2) into a O(n) worst case.
The reason we are fine with dropping `+` is that we don't use the
capture group anywhere, so, we just ensure `:: error` is not a match
but `x: error` is.
After going from O(n^2) to O(n), the 15MB mpich build log is parsed
in `1.288s`, so about 200x faster.
Just to be sure I've also updated `^CMake Error.*:` to `^CMake Error`,
so that it does not match with all the possible `:`'s in the line.
Another option is to use `.*?` there to make it quit scanning as soon as
possible, but what line that starts with `CMake Error` that does not have
a colon is really a false positive...
Installing packages with a lot of dependencies does not have an easy way
of judging the current progress (apart from running `spack spec -I pkg`
in another terminal). This change allows Spack to update the terminal's
title with status information, including its current progress as well as
information about the current and total number of packages.
- Do not store the full list of environment variables in
<prefix>/.spack/spack-build-env.txt because it may contain user secrets.
- Only store environment variable modifications upon installation.
- Variables like PATH may still contain user and system paths to make
spack-build-env.txt sourceable. Variables containing paths are
modified through prepending/appending, and if we don't apply these
to the current environment variable, we end up with statements like
`export PATH=/path/to/spack/bin` with system paths missing, meaning
no system binaries are in the path, which is a bad user experience.
- Do write the full environment to spack-build-env.txt in the staging dir,
but ensure it is readonly for the current user, to make it a bit safer
on shared systems.
Creates an environment in a temporary directory and activates it, which
is useful for a quick ephemeral environment:

$ spack env activate -p --temp
[spack-1a203lyg] $ spack add zlib
==> Adding zlib to environment /tmp/spack-1a203lyg
==> Updating view at /tmp/spack-1a203lyg/.spack-env/view
```
The DB should be what is trusted for certain operations.
If it is not present when read we should assume the
corresponding store is empty, rather than trying a
write operation during a read.
* Add a unit test
* Document what needs to be there in tests
When a symlink to a license file exists but is broken, the license symlink post-install hook fails
because os.path.exists() checks the existence of the target not the symlink itself.
os.path.lexists() is the proper function to use.
Environments push/pop scopes upon activation. If some lazily
evaluated value depending on the current configuration was
computed and cached before the scopes are pushed / popped
there will be an inconsistency in the current state.
This PR fixes the issue for stores, but it would be better
to move away from global state.
The `spack.architecture` module contains an `Arch` class that is very similar to `spack.spec.ArchSpec` but points to platform, operating system and target objects rather than "names". There's a TODO in the class since 2016:
abb0f6e27c/lib/spack/spack/architecture.py (L70-L75)
and this PR basically addresses that. Since there are just a few places where the `Arch` class was used, here we query the relevant platform objects where they are needed directly from `spack.platforms`. This permits to clean the code from vestigial logic.
Modifications:
- [x] Remove the `spack.architecture` module and replace its use by `spack.platforms`
- [x] Remove unneeded tests
* Use gnuconfig package for config file replacement for RISC-V.
This extends the changes in #26035 to handle RISC-V. Before this change,
many packages fail to configure on riscv64 due to config.guess being too
old to know about RISC-V. This is seen out of the box when clingo fails
to build from source due to pkgconfig failing to configure, throwing
error: "configure: error: cannot guess build type; you must specify one".
* Add riscv64 architecture
* Update vendored archspec from upstream project.
These archspec updates include changes needed to support riscv64.
* Update archspec's __init__.py to reflect the commit hash of archspec being used.
Cherry-picked from #25564 so this is standalone.
With this PR we can activate an environment in Spack itself, without computing changes to environment variables only necessary for "shell aware" env activation.
1. Activating an environment:
```python
spack.environment.activate(Environment(xyz)) -> None
```
this basically just sets `_active_environment` and modifies some config scopes.
2. Activating an environment **and** getting environment variable modifications for the shell:
```python
spack.environment.shell.activate(Environment(xyz)) -> EnvironmentModifications
```
This should make it easier/faster to do unit tests and scripting with spack, without the cli interface.
* Isolate bootstrap configuration from user configuration
* Search for build dependencies automatically if bootstrapping from sources
The bootstrapping logic will search for build dependencies
automatically if bootstrapping anything form sources. Any
external spec, if found, is written in a scope that is specific
to bootstrapping.
* Don't clean the bootstrap store with "spack clean -a"
* Copy bootstrap.yaml and config.yaml in the bootstrap area
- [x] Our wrapper error messages are sometimes hard to differentiate from other build
output, so prefix all errors from `die()` with '[spack cc] ERROR:'
- [x] The error we raise when running, say, `fc` without a Fortran compiler was not
clear enough. Clarify the message and the comment.
This converts everything in cc to POSIX sh, except for the parts currently
handled with bash arrays. Tests are still passing.
This version tries to be as straightforward as possible. Specifically, most conversions
are kept simple -- convert ifs to ifs, handle indirect expansion the way we do in
`setup-env.sh`, only mess with the logic in `cc`, and don't mess with the python code at
all.
The big refactor is for arrays. We can't rely on bash's nice arrays and be ignorant of
separators anymore. So:
1. To avoid complicated separator logic, there are three types of lists. They are:
* `$lsep`-separated lists, which end with `_list`. `lsep` is customizable, but we
picked `^G` (alarm bell) for `$lsep` because it's ASCII and it's unlikely that it
would actually appear in any arguments. If we need to get fancier (and I will lose
faith in the world if we do) then we could consider XON or XOFF.
* `:`-separated directory lists, which end with `_dirs`, `_DIRS`, `PATH`, or `PATHS`
* Whitespace-separated lists (like flags), which can have any other name.
Whitespace and colon-separated lists come with the territory with PATHs from env
vars and lists of flags. `^G` separated lists are what we use for most internal
variables, b/c it's more likely to work.
2. To avoid subshells, use a bunch of functions that do dirty `eval` stuff instead. This
adds 3 functions to deal with lists:
* `append LISTNAME ELEMENT [SEP]` will put `ELEMENT` at the end of the list called
`LISTNAME`. You can optionally say what separator you expect to use. Note that we
are taking advantage of everything being global and passing lists by name.
* `prepend LISTNAME ELEMENT [SEP]` like append, but puts `ELEMENT` at the start of
`LISTNAME`
* `extend LISTNAME1 LISTNAME2 [PREFIX]` appends everything in LISTNAME2 to
LISTNAME1, and optionally prepends `PREFIX` to every element (this is useful for
things like `-I`, `-isystem `, etc.
* `preextend LISTNAME1 LISTNAME2 [PREFIX]` prepends everything in LISTNAME2 to
LISTNAME1 in order, and optionally prepends `PREFIX` to every element.
The routines determine the separator for each argument by its name, so we don't have to
pass around separators everywhere. Amazingly, as long as you do not expand variables'
values within an `eval` environment, you can do all this and still preserve quoting.
When iterating over lists, the user of this API still has to set and unset `IFS`
properly.
We ended up having to ignore shellcheck SC2034 (unused variable), because using evals
all over the place means that shellcheck doesn't notice that our list variables are
actually used.
So far this is looking pretty good. I took the most complex unit test I could find
(which runs a sample link line) and ran the same command line 200 times in a shell
script. Times are roughly as follows:
For this invocation:
```console
$ bash -c 'time (for i in `seq 1 200`; do ~/test_cc.sh > /dev/null; done)'
```
I get the following performance numbers (the listed shells are what I put in `cc`'s
shebang):
**Original**
* Old version of `cc` with arrays and `bash v3.2.57` (macOS builtin): `4.462s` (`.022s` / call)
* Old version of `cc` with arrays and `bash v5.1.8` (Homebrew): `3.267s` (`.016s` / call)
**Using many subshells (#26408)**
* with `bash v3.2.57`: `25.302s` (`.127s` / call)
* with `bash v5.1.8`: `27.801s` (`.139s` / call)
* with `dash`: `15.302s` (`.077s` / call)
This version didn't seem to work with zsh.
**This PR (no subshells)**
* with `bash v3.2.57`: `4.973s` (`.025s` / call)
* with `bash v5.1.8`: `4.984s` (`.025s` / call)
* with `zsh`: `2.995s` (`.015s` / call)
* with `dash`: `1.890s` (`.0095s` / call)
Dash, with the new posix design, is easily the winner.
So there are several interesting things to note here:
1. Running the posix version in `bash` is slower than using `bash` arrays. That is to be
expected because it's doing a bunch of string processing where it likely did not have
to before, at least in `bash`.
2. `zsh`, at least on macOS, is significantly faster than the ancient `bash` they ship
with the system. Using `zsh` with the new version also makes the posix wrappers
faster than `develop`. So it's worth preferring `zsh` if we have it. I suppose we
should also try this with newer `bash` on Linux.
3. `bash v5.1.8` seems to be significantly faster than the old system `bash v3.2.57` for
arrays. For straight POSIX stuff, it's a little slower. It did not seem to matter
whether `--posix` was used.
4. `dash` is way faster than `bash` or `zsh`, so the real payoff just comes from being
able to use it. I am not sure if that is mostly startup time, but it's significant.
`dash` is ~2.4x faster than the original `bash` with arrays.
So, doing a lot of string stuff is slower than arrays, but converting to posix seems
worth it to be able to exploit `dash`.

When using modules for compiler (and/or external package), if a
package's `setup_[dependent_]build_environment` sets `PYTHONHOME`, it
can influence the python subprocess executed to gather module
information.
The error seen was:
```
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
```
But the actual hidden error happened in the `python -c 'import
json...'` subprocess, which made it return an empty string as json:
```
ModuleNotFoundError: No module named 'encodings'
```
This fix uses `python -E` to ignore `PYTHONHOME` and
`PYTHONPATH`. Should be safe here because the python subprocess code
only use packages built-in python.
The python subprocess in `environment.py` was also patched to be safe
and consistent.
* Remove redundant preserve environment code in build environment
* Remove fix for a bug in a module
See https://github.com/spack/spack/issues/3153#issuecomment-280460041,
this shouldn't be part of core spack.
* Don't module unload cray-libsci on all platforms
Spack has logic to preserve an installation prefix when it is being
overwritten: if the new install fails, the old files are restored.
This PR adds error handling for when this backup restoration fails
(i.e. the new install fails, and then some unexpected error prevents
restoration from the backup).
* Remove vestigial code to be compatible with Spack v0.9.X
* ArchSpec: reworked __repr__ to be more adherent to common Python idioms
* ArchSpec: simplified __init__.py and copy()
