* CI configuration boilerplate reduction and refactor
Configuration:
- New notation for list concatenation (prepend/append)
- New notation for string concatenation (prepend/append)
- Break out configuration files for: ci.yaml, cdash.yaml, view.yaml
- Spack CI section refactored to improve self-consistency and
composability
- Scripts are now lists of lists and/or lists of strings
- Job attributes are now listed under precedence ordered list that are
composed/merged using Spack config merge rules.
- "service-jobs" are identified explicitly rather than as a batch
CI:
- Consolidate common, platform, and architecture configurations for all CI stacks into composable configuration files
- Make padding consistent across all stacks (256)
- Merge all package -> runner mappings to be consistent across all
stacks
Unit Test:
- Refactor CI module unit-tests for refactor configuration
Docs:
- Add docs for new notations in configuration.rst
- Rewrite docs on CI pipelines to be consistent with refactored CI
workflow
* Script verbose environ, dev bootstrap
* Port #35409
* Allow users to specify root env dir
Environments managed by spack have some advantages over anonymous Environments
but they are tucked away inside spack's directory tree. This PR gives
users the ability to specify where the environments should live.
See #32823
This is also taken as an opportunity to ensure that all references are to "managed environments",
rather than "named environments". Prior to this PR some references to the latter persisted.

fixes#34879
This commit adds a new maintainer directive,
which by default extend the list of maintainers
for a given package.
The directive is backward compatible with the current
practice of having a "maintainers" list declared at
the class level.
All packages with explicit Windows support can be found with
`spack list --tags=windows`.
This also removes the documentation which explicitly lists
supported packages on Windows (which is currently out of date and
is now unnecessary with the added tags).
Note that if a package does not appear in this list, it *may*
still build on Windows, but it likely means that no explicit
attempt has been made to support it.
Since SPACK_PACKAGE_IDS is now also "namespaced" with <prefix>, it makes
more sense to call the flag `--make-prefix` and alias the old flag
`--make-target-prefix` to it.
With the new variable [prefix/]SPACK_PACKAGE_IDS you can conveniently execute
things after each successful install.
For example push just-built packages to a buildcache
```
SPACK ?= spack
export SPACK_COLOR = always
MAKEFLAGS += -Orecurse
MY_BUILDCACHE := $(CURDIR)/cache
.PHONY: all clean
all: push
ifeq (,$(filter clean,$(MAKECMDGOALS)))
include env.mk
endif
# the relevant part: push has *all* example/push/<pkg identifier> as prereqs
push: $(addprefix example/push/,$(example/SPACK_PACKAGE_IDS))
$(SPACK) -e . buildcache update-index --directory $(MY_BUILDCACHE)
$(info Pushed everything, yay!)
# and each example/push/<pkg identifier> has the install target as prereq,
# and the body can use target local $(HASH) and $(SPEC) variables to do
# things, such as pushing to a build cache
example/push/%: example/install/%
@mkdir -p $(dir $@)
$(SPACK) -e . buildcache create --allow-root --only=package --unsigned --directory $(MY_BUILDCACHE) /$(HASH) # push $(SPEC)
@touch $@
spack.lock: spack.yaml
$(SPACK) -e . concretize -f
env.mk: spack.lock
$(SPACK) -e . env depfile -o $@ --make-target-prefix example
clean:
rm -rf spack.lock env.mk example/

With this change we get the invariant that `mirror.fetch_url` and
`mirror.push_url` return valid URLs, even when the backing config
file is actually using (relative) paths with potentially `$spack` and
`$env` like variables.
Secondly it avoids expanding mirror path / URLs too early,
so if I say `spack mirror add name ./path`, it stays `./path` in my
config. When it's retrieved through MirrorCollection() we
exand it to say `file://<env dir>/path` if `./path` was set in an
environment scope.
Thirdly, the interface is simplified for the relevant buildcache
commands, so it's more like `git push`:
```
spack buildcache create [mirror] [specs...]
```
`mirror` is either a mirror name, a path, or a URL.
Resolving the relevant mirror goes as follows:
- If it contains either / or \ it is used as an anonymous mirror with
path or url.
- Otherwise, it's interpreted as a named mirror, which must exist.
This helps to guard against typos, e.g. typing `my-mirror` when there
is no such named mirror now errors with:
```
$ spack -e . buildcache create my-mirror
==> Error: no mirror named "my-mirror". Did you mean ./my-mirror?
```
instead of creating a directory in the current working directory. I
think this is reasonable, as the alternative (requiring that a local dir
exists) feels a bit pendantic in the general case -- spack is happy to
create the build cache dir when needed, saving a `mkdir`.
The old (now deprecated) format will still be available in Spack 0.20,
but is scheduled to be removed in 0.21:
```
spack buildcache create (--directory | --mirror-url | --mirror-name) [specs...]
```
This PR also touches `tmp_scope` in tests, because it didn't really
work for me, since spack fixes the possible --scope values once and
for all across tests, so tests failed when run out of order.
`spack graph` has been reworked to use:
- Jinja templates
- builder objects to construct the template context when DOT graphs are requested.
This allowed to add a new colored output for DOT graphs that highlights both
the dependency types and the nodes that are needed at runtime for a given spec.
Currently, the Spack docs show documentation for submodules *before* documentation for
submodules on package doc pages. This means that if you put docs in `__init__.py` in
some package, the docs in there will be shown *after* the docs for all submodules of the
package instead of at the top as an intro to the package. See, e.g.,
[the lockfile docs](https://spack.readthedocs.io/en/latest/spack.environment.html#module-spack.environment),
which should be at the
[top of that page](https://spack.readthedocs.io/en/latest/spack.environment.html).
- [x] add the `--module-first` option to sphinx so that it generates module docs at top of page.
## Motivation
Our parser grew to be quite complex, with a 2-state lexer and logic in the parser
that has up to 5 levels of nested conditionals. In the future, to turn compilers into
proper dependencies, we'll have to increase the complexity further as we foresee
the need to add:
1. Edge attributes
2. Spec nesting
to the spec syntax (see https://github.com/spack/seps/pull/5 for an initial discussion of
those changes). The main attempt here is thus to _simplify the existing code_ before
we start extending it later. We try to do that by adopting a different token granularity,
and by using more complex regexes for tokenization. This allow us to a have a "flatter"
encoding for the parser. i.e., it has fewer nested conditionals and a near-trivial lexer.
There are places, namely in `VERSION`, where we have to use negative lookahead judiciously
to avoid ambiguity. Specifically, this parse is ambiguous without `(?!\s*=)` in `VERSION_RANGE`
and an extra final `\b` in `VERSION`:
```
@ 1.2.3 : develop # This is a version range 1.2.3:develop
@ 1.2.3 : develop=foo # This is a version range 1.2.3: followed by a key-value pair
```
## Differences with the previous parser
~There are currently 2 known differences with the previous parser, which have been added on purpose:~
- ~No spaces allowed after a sigil (e.g. `foo @ 1.2.3` is invalid while `foo @1.2.3` is valid)~
- ~`/<hash> @1.2.3` can be parsed as a concrete spec followed by an anonymous spec (before was invalid)~
~We can recover the previous behavior on both ones but, especially for the second one, it seems the current behavior in the PR is more consistent.~
The parser is currently 100% backward compatible.
## Error handling
Being based on more complex regexes, we can possibly improve error
handling by adding regexes for common issues and hint users on that.
I'll leave that for a following PR, but there's a stub for this approach in the PR.
## Performance
To be sure we don't add any performance penalty with this new encoding, I measured:
```console
$ spack python -m timeit -s "import spack.spec" -c "spack.spec.Spec(<spec>)"
```
for different specs on my machine:
* **Spack:** 0.20.0.dev0 (c9db4e50ba045f5697816187accaf2451cb1aae7)
* **Python:** 3.8.10
* **Platform:** linux-ubuntu20.04-icelake
* **Concretizer:** clingo
results are:
| Spec | develop | this PR |
| ------------- | ------------- | ------- |
| `trilinos` | 28.9 usec | 13.1 usec |
| `trilinos @1.2.10:1.4.20,2.0.1` | 131 usec | 120 usec |
| `trilinos %gcc` | 44.9 usec | 20.9 usec |
| `trilinos +foo` | 44.1 usec | 21.3 usec |
| `trilinos foo=bar` | 59.5 usec | 25.6 usec |
| `trilinos foo=bar ^ mpich foo=baz` | 120 usec | 82.1 usec |
so this new parser seems to be consistently faster than the previous one.
## Modifications
In this PR we just substituted the Spec parser, which means:
- [x] Deleted in `spec.py` the `SpecParser` and `SpecLexer` classes. deleted `spack/parse.py`
- [x] Added a new parser in `spack/parser.py`
- [x] Hooked the new parser in all the places the previous one was used
- [x] Adapted unit tests in `test/spec_syntax.py`
## Possible future improvements
Random thoughts while working on the PR:
- Currently we transform hashes and files into specs during parsing. I think
we might want to introduce an additional step and parse special objects like
a `FileSpec` etc. in-between parsing and concretization.
* Enable hdf5 build (including +mpi) on Windows
* This includes updates to hdf5 dependencies openssl (minor edit) and
bzip2 (more-extensive edits)
* Add binary-based installation of msmpi (this is currently the only
supported MPI implementation in Spack for Windows). Note that this
does not install to the Spack-specified prefix. This implementation
will be replaced with a source-based implementation

Environments and environment views have taken over the role of `spack activate/deactivate`, and we should deprecate these commands for several reasons:
- Global activation is a really poor idea:
- Install prefixes should be immutable; since they can have multiple, unrelated dependents; see below
- Added complexity elsewhere: verification of installations, tarballs for build caches, creation of environment views of packages with unrelated extensions "globally activated"... by removing the feature, it gets easier for people to contribute, and we'd end up with fewer bugs due to edge cases.
- Environment accomplish the same thing for non-global "activation" i.e. `spack view`, but better.
Also we write in the docs:
```
However, Spack global activations have two potential drawbacks:
#. Activated packages that involve compiled C extensions may still
need their dependencies to be loaded manually. For example,
``spack load openblas`` might be required to make ``py-numpy``
work.
#. Global activations "break" a core feature of Spack, which is that
multiple versions of a package can co-exist side-by-side. For example,
suppose you wish to run a Python package in two different
environments but the same basic Python --- one with
``py-numpy@1.7`` and one with ``py-numpy@1.8``. Spack extensions
will not support this potential debugging use case.
```
Now that environments are established and views can take over the role of activation
non-destructively, we can remove global activation/deactivation.
`spack env create` enables a view by default (in a weird hidden
directory, but well...). This is asking for trouble with the other
default of `concretizer:unify:false`, since having different flavors of
the same spec in an environment, leads to collision errors when
generating the view.
A change of defaults would improve user experience:
However, `unify:true` makes most sense, since any time the issue is
brought up in Slack, the user changes the concretization config, since
it wasn't the intention to have different flavors of the same spec, and
install times are decreased.
Further we improve the docs and drop the duplicate root spec limitation
Argparse started raising ArgumentError exceptions
when the same parser is added twice. Therefore, we
perform the addition only if the parser is not there
already
Port match syntax to our unparser
A user may want to set some attributes on a package without actually modifying the package (e.g. if they want to git pull updates to the package without conflicts). This PR adds a per-package configuration section called "set", which is a dictionary of attribute names to desired values. For example:
packages:
openblas:
package_attributes:
submodules: true
git: "https://github.com/myfork/openblas"
in this case, the package will always retrieve git submodules, and will use an alternate location for the git repo.
While git, url, and submodules are the attributes for which we envision the most usage, this allows any attribute to be overridden, and the acceptable values are any value parseable from yaml.
Adds another post install hook that loops over the install prefix, looking for shared libraries type of ELF files, and sets the soname to their own absolute paths.
The idea being, whenever somebody links against those libraries, the linker copies the soname (which is the absolute path to the library) as a "needed" library, so that at runtime the dynamic loader realizes the needed library is a path which should be loaded directly without searching.
As a result:
1. rpaths are not used for the fixed/static list of needed libraries in the dynamic section (only for _actually_ dynamically loaded libraries through `dlopen`), which largely solves the issue that Spack's rpaths are a heuristic (`<prefix>/lib` and `<prefix>/lib64` might not be where libraries really are...)
2. improved startup times (no library search required)
Currently, compiler flags and variants are inconsistent: compiler flags set for a
package are inherited by its dependencies, while variants are not. We should have these
be consistent by allowing for inheritance to be enabled or disabled for both variants
and compiler flags.
- [x] Make new (spec language) operators
- [x] Apply operators to variants and compiler flags
- [x] Conflicts currently result in an unsatisfiable spec
(i.e., you can't propagate two conflicting values)
What I propose is using two of the currently used sigils to symbolized that the variant
or compiler flag will be inherited:
Example syntax:
- `package ++variant`
enabled variant that will be propagated to dependencies
- `package +variant`
enabled variant that will NOT be propagated to dependencies
- `package ~~variant`
disabled variant that will be propagated to dependencies
- `package ~variant`
disabled variant that will NOT be propagated to dependencies
- `package cflags==True`
`cflags` will be propagated to dependencies
- `package cflags=True`
`cflags` will NOT be propagated to dependencies
Syntax for string-valued variants is similar to compiler flags.
The `spack info <package>` command does not show the `Virtual Packages:` output unless the `--virtuals` command option is passed. Before this changes, the information that the command is supposed to be illustrating is not shown in the example and is confusing.
