* Refactor platform etc. to avoid circular dependencies
All the base classes in spack.architecture have been
moved to the corresponding specialized subpackages,
e.g. Platform is now defined within spack.platforms.
This resolves a circular dependency where spack.architecture
was both:
- Defining the base classes for spack.platforms, etc.
- Collecting derived classes from spack.platforms, etc.
Now it dopes only the latter.
* Move a few platform related functions to "spack.platforms"
* Removed spack.architecture.sys_type()
* Fixup for docs
* Rename Python modules according to review
|
|
|
|
|
|
* document official gfortran macOS precompiled binaries
* compile without -vvv ;) {squash this}
|
|
Currently as part of installing a package, we lock a prefix, check if
it exists, and create it if not; the logic for creating the prefix
included a check for the existence of that prefix (and raised an
exception if it did), which was redundant.
This also includes removal of tests which were not verifying
anything (they pass with or without the modifications in this PR).
|
|
* update CUDA 11 / GCC compatibility range
* additional unofficial conflict
* minor changes to comments
|
|
Modifications:
- Export platforms from spack.platforms directly, so that client modules don't have to import submodules
- Use only plain imports in test/architecture.py
- Parametrized test in test/architecture.py and put most of the setup/teardown in fixtures

This is a major rework of Spack's core core `spec.yaml` metadata format. It moves from `spec.yaml` to `spec.json` for speed, and it changes the format in several ways. Specifically:
1. The spec format now has a `_meta` section with a version (now set to version `2`). This will simplify major changes like this one in the future.
2. The node list in spec dictionaries is no longer keyed by name. Instead, it is a list of records with no required key. The name, hash, etc. are fields in the dictionary records like any other.
3. Dependencies can be keyed by any hash (`hash`, `full_hash`, `build_hash`).
4. `build_spec` provenance from #20262 is included in the spec format. This means that, for spliced specs, we preserve the *full* provenance of how to build, and we can reproduce a spliced spec from the original builds that produced it.
**NOTE**: Because we have switched the spec format, this PR changes Spack's hashing algorithm. This means that after this commit, Spack will think a lot of things need rebuilds.
There are two major benefits this PR provides:
* The switch to JSON format speeds up Spack significantly, as Python's builtin JSON implementation is orders of magnitude faster than YAML.
* The new Spec format will soon allow us to represent DAGs with potentially multiple versions of the same dependency -- e.g., for build dependencies or for compilers-as-dependencies. This PR lays the necessary groundwork for those features.
The old `spec.yaml` format continues to be supported, but is now considered a legacy format, and Spack will opportunistically convert these to the new `spec.json` format.

This modification accounts for:
1. Bootstrapping from sources using system, non-standard Python
2. Using later an ABI compatible standard Python interpreter
|
|
The system Python interpreter on rhel is patched to have
slightly different names for some architectures. This
makes it incompatible with manylinux generated extensions
for ppc64le.
To fix this issue when bootstrapping Spack we generate
on-the-fly symbolic links to the name expected by the
current interpreter if it differs from the default.

* tests: make `spack url [stats|summary]` work on mock packages
Mock packages have historically had mock hashes, but this means they're also invalid
as far as Spack's hash detection is concerned.
- [x] convert all hashes in mock package to md5 or sha256
- [x] ensure that all mock packages have a URL
- [x] ignore some special cases with multiple VCS fetchers
* url stats: add `--show-issues` option
`spack url stats` tells us how many URLs are using what protocol, type of checksum,
etc., but it previously did not tell us which packages and URLs had the issues. This
adds a `--show-issues` option to show URLs with insecure (`http`) URLs or `md5` hashes
(which are now deprecated by NIST).

Fixes removal of SPACK_ENV_PATH from PATH in the presence of trailing
slashes in the elements of PATH:
The compiler wrapper has to ensure that it is not called nested like
it would happen when gcc's collect2 uses PATH to call the linker ld,
or else the compilation fails.
To prevent nested calls, the compiler wrapper removes the elements
of SPACK_ENV_PATH from PATH.
Sadly, the autotest framework appends a slash to each element
of PATH when adding AUTOTEST_PATH to the PATH for the tests,
and some tests like those of GNU bison run cc inside the test.
Thus, ensure that PATH cleanup works even with trailing slashes.
This fixes the autotest suite of bison, compiling hundreds of
bison-generated test cases in a autotest-generated testsuite.

This PR will add a new audit, specifically for spack package homepage urls (and eventually
other kinds I suspect) to see if there is an http address that can be changed to https.
Usage is as follows:
```bash
$ spack audit packages-https <package>
```
And in list view:
```bash
$ spack audit list
generic:
Generic checks relying on global variables
configs:
Sanity checks on compilers.yaml
Sanity checks on packages.yaml
packages:
Sanity checks on specs used in directives
packages-https:
Sanity checks on https checks of package urls, etc.
```
I think it would be unwise to include with packages, because when run for all, since we do requests it takes a long time. I also like the idea of more well scoped checks - likely there will be other addresses for http/https within a package that we eventually check. For now, there are two error cases - one is when an https url is tried but there is some SSL error (or other error that means we cannot update to https):
```bash
$ spack audit packages-https zoltan
PKG-HTTPS-DIRECTIVES: 1 issue found
1. Error with attempting https for "zoltan":
<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: Hostname mismatch, certificate is not valid for 'www.cs.sandia.gov'. (_ssl.c:1125)>
```
This is either not fixable, or could be fixed with a change to the url or (better) contacting the site owners to ask about some certificate or similar.
The second case is when there is an http that needs to be https, which is a huge issue now, but hopefully not after this spack PR.
```bash
$ spack audit packages-https xman
Package "xman" uses http but has a valid https endpoint.
```
And then when a package is fixed:
```bash
$ spack audit packages-https zlib
PKG-HTTPS-DIRECTIVES: 0 issues found.
```
And that's mostly it. :)

* Add a __reduce__ method to Spec
fixes #23892
The recursion limit seems to be due to the default
way in which a Spec is serialized, following all
the attributes. It's still not clear to me why this
is related to being in an environment, but in any
case we already have methods to serialize Specs to
disk in JSON and YAML format. Here we use them to
pickle a Spec instance too.
* Downgrade to build-hash
Hopefully nothing will change the package in
between serializing the spec and sending it
to the child process.
* Add support for Python 2

* Make sure PackageInstaller does not remove the just-restored
install dir after failure in spack install --overwrite
* Remove cryptic error message and rethrow actual error

The gcc compiler can be configured to use `ld.gold` by default. It will
then call `ld.gold` explicitly when linking. When so, spack need to have
a ld.gold wrapper in PATH to inject rpaths link flags etc...
Also I wouldn't be surprised to see some package calling `ld.gold`
directly.
As for ld.gold, the argument could be made that we want to support any
package that could call ld.lld.

* Add a __reduce__ method to SpecBuildInterface
This class was confusing pickle when being serialized,
due to its scary nature of being an object that disguise
as another type.

* Make sure that spack -e. env activate b and spack -e. env deactivate error

* Conditionally remove 'context' from kwargs in _urlopen
Previously, 'context' is purged from kwargs in _urlopen to
conform to varying support for 'context' in different versions
of urllib. This fix tries to use 'context', and then removes
it if an exception is thrown and tries again.
* Specify error type in try statement in _urlopen
Specify TypeError when checking if 'context' is in kwargs
for _urlopen. Also, if try fails, check that 'context' is
in the error message before removing from kwargs.

This is a direct followup to #13557 which caches additional attributes that were added in #24095 that are expensive to compute. I had to reopen #25556 in another PR to invalidate the GitLab CI cache, but see #25556 for prior discussion.

Note: I've outlined
[here](https://github.com/spack/spack/pull/24760#issuecomment-883183175)
that gpg's trust model makes sense, since how can we trust a random

As far as I can see the double loop is not needed, since
"patch" is never used and the items in the list are tuples
of three values.

This commit adds a regression test for version selection
with preferences in `packages.yaml`. Before PR 25585 we
used negative weights in a minimization to select the
optimal version. This may lead to situations where a
dependency may make the version score of dependents
"better" if it is preferred in packages.yaml.

PackageInstaller and Package.installed disagree over what it means
for a package to be installed: PackageInstaller believes it should be
enough for a database entry to exist, whereas Package.installed
requires a database entry & a prefix directory.
This leads to the following niche issue:
* a develop spec in an environment is successfully installed
* then somehow its install prefix is removed (e.g. through a bug fixed
in #25583)
* you modify the sources and reinstall the environment
1. spack checks pkg.installed and realizes the develop spec is NOT
installed, therefore it doesn't need to have 'overwrite: true'
2. the installer gets the build task and checks the database and
realizes the spec IS installed, hence it doesn't have to install it.
3. the develop spec is not rebuilt.
The solution is to make PackageInstaller and pkg.installed agree over
what it means to be installed, and this PR does that by dropping the
prefix directory check from pkg.installed, so that it only checks the
database.
As a result, spack will create a build task with overwrite: true for
the develop spec, and the installer in fact handles overwrite requests
fine even if the install prefix doesn't exist (it just does a normal
install).

see #25563
When we have a concrete environment and we ask to install a
concrete spec from a file, currently Spack returns a list of
specs that are all the one that match the argument DAG hash.
Instead we want to compare build hashes, which also account
for build-only dependencies.
|
|
#25303 filtered padding from build output, but it's still there in binary install/relocate output,
so our CI logs are still quite long and frequently hit the limit.
- [x] add context handler from #25303 to buildcache installation as well
|
|
This allows you to run `spack graph --installed` from within an environment and get a dot graph of
its concrete specs.
- [x] make `spack graph -i` environment-aware
- [x] add code to the generated dot graph to ensure roots have min rank (i.e., they're all at the
top or left of the DAG)

Bootstrapping clingo on macOS on `develop` gives errors like this:
```
==> Error: RuntimeError: Unable to locate python command in /System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/bin
/Users/gamblin2/Workspace/spack/var/spack/repos/builtin/packages/python/package.py:662, in command:
659 return Executable(path)
660 else:
661 msg = 'Unable to locate {0} command in {1}'
>> 662 raise RuntimeError(msg.format(self.name, self.prefix.bin))
```
On macOS, `python` is laid out differently. In particular, `sys.executable` is here:
```console
Python 2.7.16 (default, May 8 2021, 11:48:02)
[GCC Apple LLVM 12.0.5 (clang-1205.0.19.59.6) [+internal-os, ptrauth-isa=deploy on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.executable
'/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python'
```
Based on that, you'd think that
`/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents` would be
where you'd look for a `bin` directory, but you (and Spack) would be wrong:
```console
$ ls /System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/
Info.plist MacOS/ PkgInfo Resources/ _CodeSignature/ version.plist
```
You need to look in `sys.exec_prefix`
```
>>> sys.exec_prefix
'/System/Library/Frameworks/Python.framework/Versions/2.7'
```
Which looks much more like a standard prefix, with understandable `bin`, `lib`, and `include`
directories:
```console
$ ls /System/Library/Frameworks/Python.framework/Versions/2.7
Extras/ Mac/ Resources/ bin/ lib/
Headers@ Python* _CodeSignature/ include/
$ ls -l /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python
lrwxr-xr-x 1 root wheel 7B Jan 1 2020 /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python@ -> python2
```
- [x] change `bootstrap.py` to use the `sys.exec_prefix` as the external prefix, instead of just
getting the parent directory of the executable.

This adds lockfile tracking to Spack's lock mechanism, so that we ensure that there
is only one open file descriptor per inode.
The `fcntl` locks that Spack uses are associated with an inode and a process.
This is convenient, because if a process exits, it releases its locks.
Unfortunately, this also means that if you close a file, *all* locks associated
with that file's inode are released, regardless of whether the process has any
other open file descriptors on it.
Because of this, we need to track open lock files so that we only close them when
a process no longer needs them. We do this by tracking each lockfile by its
inode and process id. This has several nice properties:
1. Tracking by pid ensures that, if we fork, we don't inadvertently track the parent
process's lockfiles. `fcntl` locks are not inherited across forks, so we'll
just track new lockfiles in the child.
2. Tracking by inode ensures that referencs are counted per inode, and that we don't
inadvertently close a file whose inode still has open locks.
3. Tracking by both pid and inode ensures that we only open lockfiles the minimum
number of times necessary for the locks we have.
Note: as mentioned elsewhere, these locks aren't thread safe -- they're designed to
work in Python and assume the GIL.
Tasks:
- [x] Introduce an `OpenFileTracker` class to track open file descriptors by inode.
- [x] Reference-count open file descriptors and only close them if they're no longer
needed (this avoids inadvertently releasing locks that should not be released).

This commit rework version facts so that:
1. All the information on versions is collected
before emitting the facts
2. The same kind of atom is emitted for versions
stemming from different origins (package.py
vs. packages.yaml)
In the end all the possible versions for a given
package are totally ordered and they are given
different and increasing weights staring from zero.
This refactor allow us to avoid using negative
weights, which in some configurations may make
parent node score "better" and lead to unexpected
"optimal" results.

Once PR binary graduation is deployed, the shared PR mirror will
contain binaries just built by a merged PR, before the subsequent

not depend on spack.cmd. (#25439)
* Refactor active environment getters
- Make `spack.environment.active_environment` a trivial getter for the active
environment, replacing `spack.environment.get_env` when the arguments are
not needed
- New method `spack.cmd.require_active_environment(cmd_name)` for
commands that require an environment (rather than abusing
get_env/active_environment)
- Clean up calling code to call spack.environment.active_environment or
spack.cmd.require_active_environment as appropriate
- Remove the `-e` parsing from `active_environment`, because `main.py` is
responsible for processing `-e` and already activates the environment.
- Move `spack.environment.find_environment` to
`spack.cmd.find_environment`, to avoid having spack.environment aware
of argparse.
- Refactor `spack install` command so argument parsing is all handled in the
command, no argparse in spack.environment or spack.installer
- Update documentation
* Python 2: toplevel import errors only with 'as ev'
In two files, `import spack.environment as ev` leads to errors
These errors are not well understood ("'module' object has no attribute
'environment'"). All other files standardize on the above syntax.
