Third-party Python libraries may be installed in one of several directories:
1. `lib/pythonX.Y/site-packages` for Spack-installed Python
2. `lib64/pythonX.Y/site-packages` for system Python on RHEL/CentOS/Fedora
3. `lib/pythonX/dist-packages` for system Python on Debian/Ubuntu
Previously, Spack packages were hard-coded to use the (1). Now, we query the Python installation itself and ask it which to use. Ever since #21446 this is how we've been determining where to install Python libraries anyway.
Note: there are still many packages that are hard-coded to use (1). I can change them in this PR, but I don't have the bandwidth to test all of them.
* Python: handle dist-packages and site-packages
* Query Python to find site-packages directory
* Add try-except statements for when distutils isn't installed
* Catch more errors
* Fix root directory used in import tests
* Rely on site_packages_dir property

used (#24514)
Spack allows users to set `padded_length` to pad out the installation path in
build farms so that any binaries created are more easily relocatable. The issue
with this is that the padding dominates installation output and makes it
difficult to see what is going on. The padding also causes logs to easily
exceed size limits for things like GitLab artifacts.
This PR fixes this by adding a filter in the logger daemon. If you use a
setting like this:
config:
install_tree:
padded_length: 512
Then lines like this in the output:
==> [2021-06-23-15:59:05.020387] './configure' '--prefix=/Users/gamblin2/padding-log-test/opt/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_placeholder__/__spack_path_pla/darwin-bigsur-skylake/apple-clang-12.0.5/zlib-1.2.11-74mwnxgn6nujehpyyalhwizwojwn5zga
will be replaced with the much more readable:
==> [2021-06-23-15:59:05.020387] './configure' '--prefix=/Users/gamblin2/padding-log-test/opt/[padded-to-512-chars]/darwin-bigsur-skylake/apple-clang-12.0.5/zlib-1.2.11-74mwnxgn6nujehpyyalhwizwojwn5zga
You can see that the padding has been replaced with `[padded-to-512-chars]` to
indicate the total number of characters in the padded prefix. Over a long log
file, this should save a lot of space and allow us to see error messages in
GitHub/GitLab log output.
The *actual* build logs still have full paths in them. Also lines that are
output by Spack and not by a package build are not filtered and will still
display the fully padded path. There aren't that many of these, so the change
should still help reduce file size and readability quite a bit.

015e29efe105ddd039e8b395e12cf78a3787ebb3 that introduced this section to the
documentation said “two” here instead of the actual count, three.
9f54cea5c500bb19d2301149460c741e96be1f8b then added a fourth, BLAS/LAPACK.
Rather than trying to keep this leading count in sync, this change just replaces
the wording with something more generic/stable.

* fix remaining flake8 errors
* imports: sort imports everywhere in Spack
We enabled import order checking in #23947, but fixing things manually drives
people crazy. This used `spack style --fix --all` from #24071 to automatically
sort everything in Spack so PR submitters won't have to deal with it.
This should go in after #24071, as it assumes we're using `isort`, not
`flake8-import-order` to order things. `isort` seems to be more flexible and
allows `llnl` mports to be in their own group before `spack` ones, so this
seems like a good switch.

`dateutil.parser` was an optional dependency for CVS tests. It was failing on macOS
beacuse the dateutil types were not being installed, and mypy was failing *even when the
CVS tests were skipped*. This seems like it was an oversight on macOS --
`types-dateutil-parser` was not installed there, though it was on Linux unit tests.
It takes 6 lines of YAML and some weird test-skipping logic to get `python-dateutil` and
`types-python-dateutil` installed in all the tests where we need them, but it only takes
4 lines of code to write the date parser we need for CVS, so I just did that instead.
Note that CVS date format can vary from system to system, but it seems like it's always
pretty similar for the parts we care about.
- [x] Replace dateutil.parser with a simpler date regex
- [x] Lose the dependency on `dateutil.parser`

Previous tests of `spack style` didn't really run the tools --
they just ensure that the commands worked enough to get coverage.
This adds several real tests and ensures that we hit the corner
cases in `spack style`. This also tests sucess as well as failure
cases.
|
|
This consolidates code across tools in `spack style` so that each
`run_<tool>` function can be called indirecty through a dictionary
of handlers, and os that checks like finding the executable for the
tool can be shared across commands.
- [x] rework `spack style` to use decorators to register tools
- [x] define tool order in one place in `spack style`
- [x] fix python 2/3 issues to Get `isort` checks working
- [x] make isort error regex more robust across versions
- [x] remove unused output option
- [x] change vestigial `TRAVIS_BRANCH` to `GITHUB_BASE_REF`
- [x] update completion
|
|
- [x] Remove flake8-import-order checks, as we only need isort for this
- [x] Clean up configuration and requirements

When using Python 3.9.6, Spack is no longer able to fetch anything. Commands like `spack fetch` and `spack install` all break.
Python 3.9.6 includes a [new change](https://github.com/python/cpython/pull/25853/files#diff-b3712475a413ec972134c0260c8f1eb1deefb66184f740ef00c37b4487ef873eR462) that means that `scheme` must be a string, it cannot be None. The solution is to use an empty string like the method default.
Fixes #24644. Also see https://github.com/Homebrew/homebrew-core/pull/80175 where this issue was discovered by CI. Thanks @branchvincent for reporting such a serious issue before any actual users encountered it!

We should not fail the generate stage simply due to the presence of
a broken-spec somewhere in the DAG. Only fail if the known broken
spec needs to be rebuilt.

This PR adds a context manager that permit to group the common part of a `when=` argument and add that to the context:
```python
class Gcc(AutotoolsPackage):
with when('+nvptx'):
depends_on('cuda')
conflicts('@:6', msg='NVPTX only supported in gcc 7 and above')
conflicts('languages=ada')
conflicts('languages=brig')
conflicts('languages=go')
```
The above snippet is equivalent to:
```python
class Gcc(AutotoolsPackage):
depends_on('cuda', when='+nvptx')
conflicts('@:6', when='+nvptx', msg='NVPTX only supported in gcc 7 and above')
conflicts('languages=ada', when='+nvptx')
conflicts('languages=brig', when='+nvptx')
conflicts('languages=go', when='+nvptx')
```
which needs a repetition of the `when='+nvptx'` argument. The context manager might help improving readability and permits to group together directives related to the same semantic aspect (e.g. all the directives needed to model the behavior of `gcc` when `+nvptx` is active).
Modifications:
- [x] Added a `when` context manager to be used with package directives
- [x] Add unit tests and documentation for the new feature
- [x] Modified `cp2k` and `gcc` to show the use of the context manager

ci: only write to broken-specs list on SpackError
Only write to the broken-specs list when `spack install` raises a SpackError,
instead of writing to this list unnecessarily when infrastructure-related problems
prevent a develop job from completing successfully.

If two Specs have the same hash (and prefix) but are not equal, Spack
originally had logic to detect this and raise an error (since both
cannot be installed in the same place). Recently this has eroded and
the check no-longer works; moreover, when defining projections (which
may truncate the hash or other distinguishing properties from the
prefix) Spack was also failing to detect collisions (in both of these
cases, Spack would overwrite the old prefix with the new Spec).
This PR maintains a list of all "taken" prefixes: if a hash is not
registered (i.e. recorded as installed in the database) but the prefix
is occupied, that is a collision. This can detect collisions created
by defining projections (specifically when they omit the hash).
The PR does not detect collisions where specs have the same hash
(and prefix) but are not equal.

Prior to any Spack build, Spack modifies PATH etc. to help the build
find the dependencies it needs. It also allows any package to define
custom environment modifications (and furthermore a package can
specify environment modifications to apply when it is used as a
dependency). If an external package defines custom environment
modifications that alter PATH, and the external package is in a merged
or system prefix, then that prefix could "override" the Spack-built
packages.
This commit reorders environment modifications so that PrependPath
actions which expose Spack-built packages override PrependPath actions
for custom environment modifications of external packages.
In more detail, the original order of environment modifications is:
* Modules
* Compiler flag variables
* PATH, CMAKE_PREFIX_PATH, and PKG_CONFIG_PATH for dependencies
* Custom package.py modifications in the following order:
* dependencies
* root
This commit changes the order:
* Modules
* Compiler flag variables
* For each external dependency
* PATH, CMAKE_PREFIX_PATH, and PKG_CONFIG_PATH modifications
* Custom modifications
* For each Spack-built dependency
* PATH, CMAKE_PREFIX_PATH, and PKG_CONFIG_PATH modifications
* Custom modifications

Spack pipelines need to take specific actions internally that depend
on whether the pipeline is being run on a PR to spack or a merge to
the develop branch. Pipelines can also run in other repositories,
which represents other possible use cases than just the two mentioned
above. This PR creates a "SPACK_PIPELINE_TYPE" gitlab variable which
is propagated to rebuild jobs, and is also used internally to determine
which pipeline-specific tasks to run.
One goal of the PR is fix an issue where rebuild jobs which failed on
develop pipelines did not properly report the broken full hash to the
"broken-specs-url".

* Force the Python interpreter with an env variable
This commit forces the Python interpreter with an
environment variable, to ensure that the Python set
by the "setup-python" action is the one being used.
Due to the policy adopted by Spack to prefer python3
over python we may end up picking a Python 3.X
interpreter where Python 2.7 was meant to be used.
* Revert "Update conftest.py (#24473)"
This reverts commit 477c8ce8205ec149fa897c9d83e530815c978d8b.
* Make python-dateutil a soft dependency for unit tests
Before #23212 people could clone spack and run
```
spack unit-tests
```
while now this is not possible, since python-dateutil is
a required but not vendored dependency. This change makes
it not a hard requirement, i.e. it will be used if found
in the current interpreter.

This commit fixes a subtle bug that may occur when
a package is a "possible_provider" of a virtual but
no "provides_virtual" can be deduced. In that case
the cardinality constraint on "provides_virtual"
may arbitrarily assign a package the role of provider
even if the constraints for it to be one are not fulfilled.
The fix reworks the logic around three concepts:
- "possible_provider": a package may provide a virtual if some constraints are met
- "provides_virtual": a package meet the constraints to provide a virtual
- "provider": a package selected to provide a virtual
|
|
Facts used to compute weights for providers only need
the package name, since the other attributes are computed
as part of the solve.
