- [x] Solver now uses the Python interface to clingo
- [x] can extract unsatisfiable cores from problems when things go wrong
- [x] use Python callbacks for versions instead of choice rules (this may
ultimately hurt performance)

This change makes improvements to the `spack ci rebuild` command
which supports running gitlab pipelines on PRs from forks. Much
of this has to do with making sure we can run without the secrets
previously required for running gitlab pipelines (e.g signing key,
aws credentials, etc). Specific improvements in this PR:
Check if spack has precisely one signing key, and use that information
as an additional constraint on whether or not we should attempt to sign
the binary package we create.
Also, if spack does not have at least one public key, add the install
option "--no-check-signature"
If we are running a pipeline without any profile or environment
variables allowing us to push to S3, the pipeline could still
successfully create a buildcache in the artifacts and move on. So
just print a message and move on if pushing either the buildcache
entry or cdash id file to the remote mirror fails.
When we attempt to generate a pacakge or gpg key index on an S3
mirror, and there is nothing to index, just print a warning and
exit gracefully rather than throw an exception.
Support the use of PR-specific mirrors for temporary binary pkg
storage. This will allow quality-of-life improvement for developers,
providing a place to store binaries over the lifetime of a PR, so
that they must only wait for packages to rebuild from source when
they push a new commit that causes it to be necessary.
Replace two-pass install with a single pass and the new option:
--require-full-hash-match. Doing this also removes the need to
save a copy of the spack.yaml to be copied over the one spack
rewrites in between the two spack install passes.
Work around a mirror configuration issue caused by using
spack.util.executable to do the package installation.
* Update pipeline trigger jobs for PRs from forks
Moving to PRs from forks relies on external synchronization script
pushing special branch names. Also secrets will only live on the
spack mirror project, and must be propagated to the E4S project via
variables on the trigger jobs.
When this change is merged, pipelines will not run until we update
the "Custom CI configuration path" in the Gitlab CI Settings, as the
name of the file has changed to better reflect its purpose.
* Arg to MirrorCollection is used exclusively, so add main remote mirror to it
* Compute full hash less frequently
* Add tests covering index generation error handling code

Added a command to set up Spack for our tutorial at
https://spack-tutorial.readthedocs.io.
The command does some common operations we need first-time users to do.
Specifically:
- checks out a particular branch of Spack
- deletes spurious configuration in `~/.spack` that might be
left over from prior parts of the tutorial
- adds a mirror and trusts its public key
|
|
* "spack install" now has a "--require-full-hash-match" option, which
forces Spack to skip an available binary package when the full hash
doesn't match. Normally only a DAG-hash match is required, which
ensures equivalent Specs, but does not account for changing logic
inside the associated package.
* Add a local binary cache index which tracks specs that have a binary
install available in a remote binary cache. It is updated with
"spack buildcache list" or for a given spec when a binary package
is retrieved for that Spec.

Don't require SPACK_ROOT for sourcing setup-env.csh and make output more consistent
|
|
Zsh and newer versions of bash have a builtin `which` function that will
show you if a command is actually an alias or a function. For functions,
the entire function is printed, and our `spack()` function is quite long.
Instead of printing out all that, make the `spack()` function a wrapper
around `_spack_shell_wrapper()`, and include some no-ops in the
definition so that users can see where it was created and where Spack is
installed.
Here's what the new output looks like in zsh:
```console
$ which spack
spack () {
: this is a shell function from: /Users/gamblin2/src/spack/share/spack/setup-env.sh
: the real spack script is here: /Users/gamblin2/src/spack/bin/spack
_spack "$@"
return $?
}
```
Note that `:` is a no-op in Bourne shell; it just discards anything after
it on the line. We use it here to embed paths in the function definition
(as comments are stripped).

This reverts #18359 and follow-on PRs intended to address issues with
#18359 because that PR changes the hash of all specs. A future PR will
reintroduce the changes.
* Revert "Fix location in spec.yaml where we look for full_hash (#19132)"
* Revert "Fix fetch of spec.yaml files from buildcache (#19101)"
* Revert "Merge pull request #18359 from scottwittenburg/add-binary-distribution-cache-manager"

This changes makes sure that when we run the pipeline job that updates
the buildcache package index on the remote mirror, we also update the
key index. The public keys corresponding to the signing keys used to
sign the package was pushed to the mirror as a part of creating the
buildcache index, so this is just ensuring those keys are reflected
in the key index.
Also, this change makes sure the "spack buildcache update-index"
job runs even when there may have been pipeline failures, since we
would like the index always to reflect the true state of the mirror.

* Rework spack.util.web.list_url()
list_url() now accepts an optional recursive argument (default: False)
for controlling whether to only return files within the prefix url or to
return all files whose path starts with the prefix url. Allows for the
most effecient implementation for the given prefix url scheme. For
example, only recursive queries are supported for S3 prefixes, so the
returned list is trimmed down if recursive == False, but the native
search is returned as-is when recursive == True. Suitable
implementations for each case are also used for file system URLs.
* Switch to using an explicit index for public keys
Switches to maintaining a build cache's keys under build_cache/_pgp.
Within this directory is an index.json file listing all the available
keys and a <fingerprint>.pub file for each such key.
- Adds spack.binary_distribution.generate_key_index()
- (re)generates a build cache's key index
- Modifies spack.binary_distribution.build_tarball()
- if tarball is signed, automatically pushes the key used for signing
along with the tarball
- if regenerate_index == True, automatically (re)generates the build
cache's key index along with the build cache's package index; as in
spack.binary_distribution.generate_key_index()
- Modifies spack.binary_distribution.get_keys()
- a build cache's key index is now used instead of programmatic
listing
- Adds spack.binary_distribution.push_keys()
- publishes keys from Spack's keyring to a given list of mirrors
- Adds new spack subcommand: spack gpg publish
- publishes keys from Spack's keyring to a given list of mirrors
- Modifies spack.util.gpg.Gpg.signing_keys()
- Accepts optional positional arguments for filtering the set of keys
returned
- Adds spack.util.gpg.Gpg.public_keys()
- As spack.util.gpg.Gpg.signing_keys(), except public keys are
returned
- Modifies spack.util.gpg.Gpg.export_keys()
- Fixes an issue where GnuPG would prompt for user input if trying to
overwrite an existing file
- Modifies spack.util.gpg.Gpg.untrust()
- Fixes an issue where GnuPG would fail for input that were not key
fingerprints
- Modifies spack.util.web.url_exists()
- Fixes an issue where url_exists() would throw instead of returning
False

`spack install --yes-to-all` doesn't actually make the build non-interactive,
but that is why people typically use it. This documents that you must also
specify `--no-checksum` for a fully non-interactive build.

compiler find (#18165)
* spack config: default modification scope can be an environment
The previous model was that environments are the highest priority config
scope for config reading operations, but were not considered for config
writing operations. Now, the active environment is the highest priority
config scope for both reading and writing operations.
Now spack config add, spack external find and spack compiler set environment
configuration in the environment by default if an environment is active. This is a
change in default behavior for these routines, but better matches the mental
model for an environment taking precedence over the user's default config file.
* add scope argument to 'spack external find' to choose non-default scope
* Increase testing for config modifications on environments

Packages can implement “detect_version” to support detection
of external instances of a package. This is generally easier
than implementing “determine_spec_details”. The API for
determine_version is similar: for example you can return
“None” to indicate that an executable is not an instance
of a package.
Users may implement a “determine_variants” method for a package.
When doing external detection, executables are grouped by version
and each group results in a single invocation of “determine_variants”
for the associated spec. The method returns a string specifying
the variants for the package. The method may additionally return
a dictionary representing extra attributes for the package.
These will be stored in the spec yaml and can be retrieved
from self.spec.extra_attributes
The Spack GCC package has been updated with an implementation
of “determine_variants” which adds the following extra
attributes to the package: c, cxx, fortran
|
|
The YAML config for paths and modules of external packages has
changed: the new format allows a single spec to load multiple
modules. Spack will automatically convert from the old format
when reading the configs (the updates do not add new essential
properties, so this change in Spack is backwards-compatible).
With this update, Spack cannot modify existing configs/environments
without updating them (e.g. “spack config add” will fail if the
configuration is in a format that predates this PR). The user is
prompted to do this explicitly and commands are provided. All
config scopes can be updated at once. Each environment must be
updated one at a time.

On Cray platforms, we rely heavily on the module system to figure out
what targets, compilers, etc. are available. This unfortunately means
that we shell out to the `module` command as part of platform
initialization.
Because we run subcommands in a shell, we can get infinite recursion if
`setup-env.sh` and friends are in some init script like `.bashrc`.
This fixes the infinite loop by adding guards around `setup-env.sh`,
`setup-env.csh`, and `setup-env.fish`, to prevent recursive
initializations of Spack. This is safe because Spack never shells out to
itself, so we do not need it to be initialized in subshells.
- [x] add recursion guard around `setup-env.sh`
- [x] add recursion guard around `setup-env.csh`
- [x] add recursion guard around `setup-env.fish`

* Move flake8 tests on Github Actions
* Move shell test to Github Actions
* Moved documentation build to Github Action
* Don't run coverage on Python 2.6
Since we get connection errors consistently on Travis
when trying to upload coverage results for Python 2.6,
avoid computing coverage entirely to speed-up tests.

* Activate environment in container file
This PR will ensure that the container recipes will build the spack
environment by first activating the environment.
* Deactivate environment before environment collection
For Singularity, the environment must be deactivated before running the
command to collect the environment variables. This is because the
environment collection uses `spack env activate`.

* remove three commands that have been deprecated since v0.13.0
|
|
* Start moving toward a json buildcache index
* Add spec and database index schemas
* Add a schema for buildcache spec.yaml files
* Provide a mode for database class to generate buildcache index
* Update db and ci tests to validate object w/ new schema
* Remove unused temporary upload-s3 command
* Use database class to generate buildcache index
* Do not generate index with each buildcache creation
* Make buildcache index mode into a couple of constructor args to Database class
* Use keyword args for _createtarball
* Parse new json index when we get specs from buildcache
Now that only one index file per mirror needs to be fetched in
order to have all the concrete specs for binaries available on the
mirror, we can just fetch and refresh the cached specs every time
instead of needing to use the '-f' flag to force re-reading.

This fixes a fork bomb in `spack versions`. Recursive generation of pools
to scrape URLs in `_spider` was creating large numbers of processes.
Instead of recursively creating process pools, we now use a single
`ThreadPool` with a concurrency limit.
More on the issue: having ~10 users running at the same time spack
versions on front-end nodes caused kernel lockup due to the high number
of sockets opened (sys-admin reports ~210k distributed over 3 nodes).
Users were internal, so they had ulimit -n set to ~70k.
The forking behavior could be observed by just running:
$ spack versions boost
and checking the number of processes spawned. Number of processes
per se was not the issue, but each one of them opens a socket
which can stress `iptables`.
In the original issue the kernel watchdog was reporting:
Message from syslogd@login03 at May 19 12:01:30 ...
kernel:Watchdog CPU:110 Hard LOCKUP
Message from syslogd@login03 at May 19 12:01:31 ...

* add subcommand `spack view copy/relocate`
* update bash completions
* add copy/relocate commands to view tests
* allow copied views to be removed
|

This change also adds a code path through the spack ci pipelines
infrastructure which supports PR testing on the Spack repository.
Gitlab pipelines run as a result of a PR (either creation or pushing
to a PR branch) will only verify that the packages in the environment
build without error. When the PR branch is merged to develop,
another pipeline will run which results in the generated binaries
getting pushed to the binary mirror.
