The name of the debug log written by the cc compiler wrapper was given
by Spec.short_spec, which includes the architecture. Somewhere along
the line Spec.format started adding spaces around the architecture
property so the filename started including spaces; the cc wrapper
script appears to ignore this, so files like spack-cc-bzip2-....in.log
(which record the wrapped compiler invocations) were not being
generated. This uses a different format string from the spec to
generate the wrapper log file names (which does not include spaces).
* when a user-provided spec refers to an already-installed package, packages with patches applied were causing validation errors based on the recorded variants in the package's class
* avoid checks on all reserved variants (not just 'patches')
* basic functionality to install spec from a binary cache when it's available; this spiders each cache for each package and could likely be more efficient by caching the results of the first check
* add spec to db after installing from binary cache
* cache (in memory) spec listings retrieved from binary caches
* print a warning vs. failing when no mirrors are configured to retrieve pre-built Spack packages
* make automatic retrieval of pre-built spack packages from mirrors optional
* no code was using the links stored in the dictionary returned by get_specs, so this simplifies the logic to return only a set of specs
* print package prefix after installing from binary cache
* provide more information to user on install progress
This updates the logic for Package.extends so that if the spec
associated with the package is not concrete, it will report true if
the package *could extend* the given spec; generally speaking a
package could extend a spec as long as none of the details associated
with its extendee spec conflict with the given spec. When the spec
associated with the package is concrete, this function will only
report whether the package *does extend* the given spec. When both
the specs are concrete, the semantics are the same as before.
* When creating a tar of a package for a build cache, symlinks are
preserved (the corresponding path in the newly-created tarfile will
be a symlink rather than a copy of the file)
* Dont add external packages to a build cache
* When installing from binary cache, don't create install prefix until
verification is complete
* Fixes#5754
Previously when RepoPath.repo_for_pkg was invoked with a string,
it did not check if the string included a namespace. Any
namespace-qualified package provided as a string would not be found
(at which point the behavior was to return the highest-precedence
repository).
* handle nested namespaces for packages specified as strings in repo_for_pkg
* add preliminary repository tests
* add test which replicates #5754
* refactor repo tests with fixtures
* define repo_path equivalent at test-level scope for repo tests
* add tests for unknown namespace/package
* rename fixture function (no longer prefixed with 'test_')
Internally we work against a branch named 'llnl/develop', which
mirrors the public repository's `develop` branch.
It's useful to be able to run flake8 on our changes, using
`llnl/develop` as the base branch instead of `develop`.
Internally the flake8 subcommand generates the list of changes files
using a hardcoded range of `develop...`.
This makes the base of that range a command line option, with a
default of `develop`.
That lets us do this:
```
spack flake8 --base llnl/develop
```
which uses a range of `llnl/develop...`.
'spack install' can now reinstall a spec even if it has dependents, via
the --overwrite option. This option moves the current installation in a
temporary directory. If the reinstallation is successful the temporary
is removed, otherwise a rollback is performed.
- new E741 flake8 checks disallow 'l', 'O', and 'I' as variable names
- rework parts of the code that use this, to be compliant
- we could add exceptions for this, but we're trying to mostly keep up
with PEP8 and we already have more than a few exceptions.
- When you don't use wildcards, flake8 will find places where you used an
undefined name.
- This commit has all the bugfixes resulting from this static check.
There are now separate flake8 configs for core vs. packages:
- core has a smaller set of flake8 exceptions
- packages allow `from spack import *` and module globals
- Allows core to take advantage of static checking for undefined names
- Allows packages to keep using Spack tricks like `from spack import *`
and dependencies setting globals for dependents.
* Update Getting Started docs to clarify that full Xcode suite is required for qt
* Better error message when only the command-line tools are installed
I'm tracking down a problem with the perl package that's been
generating this error:
```
OSError: OSError: [Errno 2] No such file or directory: '/blah/blah/blah/lib/5.24.1/x86_64-linux/Config.pm~'
```
The real problem is upstream, but it's being masked by an exception
raised in `filter_file`s finally block.
In my case, `backup` is `False`.
The backup is created around line 127, the `re.sub()` calls
fails (working on that), the `except` block fires and moves the backup
file back, then the finally block tries to remove the non-existent
backup file.
This change just avoids trying to remove the non-existent file.
- The shell script uses arrays and hence only works on sophisticated shells and not the default `sh`. For clarity the shebang `#!/bin/bash` has been used instead.
- This fakes out GitFetchStrategy to try code paths for different git
versions.
- This allows us to test code paths for old versions using a newer git
version.
- Tests use a session-scoped mock stage directory so as not to interfere
with the real install.
- Every test is forced to clean up after itself with an additional check.
We now automatically assert that no new files have been added to
`spack.stage_path` during each test.
- This means that tests that fail installs now need to clean up their
stages, but in all other cases the check is useful.
- Be explicit about stage creation during the install process.
- This avoids accidental creation of stages
- e.g., during `spack install --fake`, stages were erroneously recreated
after being destroyed
- This prevents the main spack install from being clusttered by
invocations of `spack test`.
- This uses a session-scoped stage fixture to ensure tests don't
interfere.
- Spack's core package interface was previously overly stateful, in that
calling methods like `do_stage()` could change your working directory.
- This removes Stage's `chdir` and `chdir_to_source` methods and replaces
their usages with `with working_dir(stage.path)` and `with
working_dir(stage.source_path)`, respectively. These ensure the
original working directory is preserved.
- This not only makes the API more usable, it makes the tests more
deterministic, as previously a test could leave the current working
directory in a bad state and cause subsequent tests to fail
mysteriously.
- Assertion would search for root through all possible paths.
- It's also really slow.
- This isn't needed anymore. We're pretty good at ensuring single-rooted
DAGs, and this assertion has never been thrown.
- This shaves another 6 seconds off r-rminer concretization
- This reduces concretization time for r-rminer from over 1 minute to
only 16 seconds.
- OrderedDict ends up taking a *lot* of time to compare larger specs.
- An OrderedDict isn't actually needed here. It's actually not possible
to find duplicates, and we end up sorting the contents of the
OrderedDict anyway.
- This is an optimization to the way traverse_edges iterates over
successors.
- Previous version called dependencies_dict(), which involved a lot of
redundant work (creating dicts and calling caonical_deptype)
- Spack ends up constructing compilers frequently from YAML data.
- This caches the result of parsing the compiler config
- The logic in compilers/__init__.py could use a bigger cleanup, but this
makes concretization much faster for now.
- on macOS, this also ensures that xcrun is called only twice, as opposed
to every time a new compiler object is constructed.
This adds a workflow section on how to use spack on Docker.
It provides an example on the best-practices I collected over the
last months and circumvents the common pitfalls I tapped in.
Works with MPI, CUDA, Modules, execution as root, etc.
Background: Developed initially for PIConGPU.
* Make --trusted default when running spack gpg list
Currently running `spack gpg list` with no arguments returns nothing. You must supply either the `--trusted` or the `--signing` options. The idea here is to return some initial data to the user when the command is run. The alternative is to return an error, telling the user to select one of the two options.
* Add an extra test case for the empty list command
Fixes the issue with code coverage
This isn't a rework of the concretizer but it speeds things up a LOT.
The main culprits were:
1. Variant code, `provider_index`, and `concretize.py` were calling
`spec.package` when they could use `spec.package_class`
- `spec.package` looks up a package instance by `Spec`, which requires a
(fast-ish but not that fast) DAG compare.
- `spec.package_class` just looks up the package's class by name, and you
should use this when all you need is metadata (most of the time).
- not really clear that the current way packages are looked up is
necessary -- we can consider refactoring that in the future.
2. `Repository.repo_for_pkg` parses a `str` argument into a `Spec` when
called with one, via `@_autospec`, but this is not needed.
- Add some faster code to handle strings directly and avoid parsing
This speeds up concretization 3-9x in my limited tests. Still not super
fast but much more bearable:
Before:
- `spack spec xsdk` took 33.6s
- `spack spec dealii` took 1m39s
After:
- `spack spec xsdk` takes 6.8s
- `spack spec dealii` takes 10.8s
* Do not call setup_package for fake installs
- setup package could fail if ``setup_dependent_environment`` or other
routines expected to use executables from dependencies
- xpetsc and boost try to get python config variables in
`setup_dependent_package`; this would cause them not to be
fake-installable
* Remove vestigial deptype_query argument to Spec.traverse()
- The `deptype_query` argument isn't used anymore -- it's only passed
around and causes confusion when calling traverse.
- Get rid of it and just keep the `deptypes` argument
* Don't print redundant messages when installing dependencies
- `do_install()` was originally depth-first recursive, and printed "<pkg>
already installed in ..." multiple times for packages as recursive
calls encountered them.
- For much cleaner output, use spec.traverse(order='post') to install
dependencies instead
* Add package for aspell and ass't dictionaries
Add a package definition for aspell.
Add a handful of dictionaries to convince myself that the support for
a bunch of dictionaries works.
* Flake8 cleanup
* Use six's version of urlparse
`urlparse` is not python3 friendly. This works around it (stolen from
`.../cmd/md5.py`).
* Fix incorrect trimming regexp
* Clean up dictionary build
- more parsimonious use of `which` (`make()` has already been made)
- use `sh` instead of `bash`
* Use a helper method to generate info for variants
I figured out my issues with static methods. I *think* that it this
is pythonic.
* Convert aspell to an extendable package
Convert aspell to be extendable and rework the dictionaries to be
extensions.
As it stands, there's a great deal of cut and paste in the
dictionaries, I'll abstract that out next.
The {de,}activate methods copy a great deal of code out of
package.py. Perhaps there's a better way....
* Create AspellDictPackage and use it for the dictionaries
Reduce the repeated code, pull it into a base class.
I'm confused about why 'from spack import *' wasn't more useful in the
base class.
* Oops, -de & -es should be AspellDictPackages too
* Typo: pakcage -> package
* Address some commentary
* Update copyright dates, 2016->2017
* spec and spec.package.spec can refer to different objects in the
database. When these two instances of spec differ in terms of
the value of the 'concrete' property, Spec._mark_concrete can
fail when checking Spec.package.installed (which requires
package.spec to be concrete). This skips the check for
spec.package.installed when _mark_concrete is called with
'True' (in other words, when the database is marking all specs
as being concrete).
* add test to confirm this fixes#5293
* edits to address issues where spack concretization attempts to set properties on already-installed specs
* most added checks only need to check if the spec is concrete; they dont also need to check if the package is installed
* add test to ensure that patches are not applied to an installed spec
* add test to ensure that an error is detected when a dependent requests a dependency constraint which conflicts with a requested installed dependency
Fixes#5455
All methods within setup_package use an EnvironmentModifications object
to control the environment. Those modifications are applied at the end
of setup_package. Module loads for the build environment need to be
done after the rest of the environment modifications are applied, as
otherwise Spack may unset variables set by those modules (for example
LD_LIBRARY_PATH).
closes#2884closes#4684
In #1848 we decided to use `Spec.format` to expand certain tokens in
the module file naming scheme or in the environment variable name.
Not all the tokens that are allowed in `Spec.format` make sense in
module file generation. This PR restricts the set of tokens that can
be used, and adds tests to check that the intended behavior is respected.
Additionally, the names of environment variables set/modified by module
files were, up to now, always uppercase. There are packages though that
require case sensitive variable names to honor certain behaviors (e.g.
OpenMPI). This PR restricts the uppercase transformation in variable
names to `Spec.format` tokens.
fixes#5587
In trying to preserve patch ordering, #5476 made equality inconsistent
for the added 'patches' variant. This commit maintains the original
weak ordering of patch applications while preserving consistency of
comparisons. The ordering DOES NOT enter the hashing mechanism. It's
supposed to be a hotfix, while we think of a cleaner and more-permanent
solution.
- This steals the magic regular expressions that CTest uses to parse log
files and addds them to Spack. See here:
https://github.com/Kitware/CMake/blob/master/Source/CTest/cmCTestBuildHandler.cxx
These are BSD licensed, so the port is in `externa/ctest_log_parser.py`
- We currently use these to do better filtering of errors from build
output. Plan is to use them to generate good CDash output.

```
- A package can depend on a special patched version of its dependencies.
- The `Spec` YAML (and therefore the hash) now includes the sha256 of
the patch in the `Spec` YAML, which changes its hash.
- The special patched version will be built separately from a "vanilla"
version of the same package.
- This allows packages to maintain patches on their dependencies
without affecting either the dependency package or its dependents.
This could previously be accomplished with special variants, but
having to add variants means the hash of the dependency changes
frequently when it really doesn't need to. This commit allows the
hash to change *just* for dependencies that need patches.
- Patching dependencies shouldn't be the common case, but some packages
(qmcpack, hpctoolkit, openspeedshop) do this kind of thing and it
makes the code structure mirror maintenance responsibilities.
- Note that this commit means that adding or changing a patch on a
package will change its hash. This is probably what *should* happen,
but we haven't done it so far.
- Only applies to `patch()` directives; `package.py` files (and their
`patch()` functions) are not hashed, but we'd like to do that in the
future.
- The interface looks like this: `depends_on()` can optionally take a
patch directive or a list of them:
depends_on(<spec>,
patches=patch(..., when=<cond>),
when=<cond>)
# or
depends_on(<spec>,
patches=[patch(..., when=<cond>),
patch(..., when=<cond>)],
when=<cond>)
- Previously, the `patch()` directive only took an `md5` parameter. Now
it only takes a `sha256` parameter. We restrict this because we want
to be consistent about which hash is used in the `Spec`.
- A side effect of hashing patches is that *compressed* patches fetched
from URLs now need *two* checksums: one for the downloaded archive and
one for the content of the patch itself. Patches fetched uncompressed
only need a checksum for the patch. Rationale:
- we include the content of the *patch* in the spec hash, as that is
the checksum we can do consistently for patches included in Spack's
source and patches fetched remotely, both compressed and
uncompressed.
- we *still* need the patch of the downloaded archive, because we want
to verify the download *before* handing it off to tar, unzip, or
another decompressor. Not doing so is a security risk and leaves
users exposed to any arbitrary code execution vulnerabilities in
compression tools.
- Functions returned by directives were all called `_execute`, which made
reading stack traces hard because you couldn't tell what directive a
frame came from.
- renamed them all to `_execute_<directive>`
- Exceptions in directives were only really used in one or two places --
get rid of the boilerplate init functions and let the callsite specify
the message.
- move `spack.cmd.checksum.get_checksums` to `spack.util.web.spider_checksums`
- move `spack.error.NoNetworkError` to `spack.util.web.NoNetworkError` since
it is only used there.
- Previously, dependencies and dependency_types were stored as separate
dicts on Package.
- This means a package can only depend on another in one specific way,
which is usually but not always true.
- Prior code unioned dependency types statically across dependencies on
the same package.
- New code stores dependency relationships as their own object, with a
spec constraint and a set of dependency types per relationship.
- Dependency types are now more precise
- There is now room to add more information to dependency relationships.
- New Dependency class lives in dependency.py, along with deptype
definitions that used to live in spack.spec.
Move deptype definitions to spack.dependency
* Add '--test=all' and '--test=root' options to test either the root or the root and all dependencies.
* add a test dependency type that is only used when --test is enabled.
* test dependencies are not added to the spec, but they are provided in the test environment.
closes#5473
Prior to this PR we were not exiting early for external packages, which
caused the `configure_options` property of the contexts to fail with
e.g. a key error because the DAG gets truncated for them. More
importantly Spack configure options don't make any sense for externals.
Now we exit early, and leave a message in the module file clarifying
that this package has been installed outside of Spack.
closes#5201
Currently, if a user sets an external package to have a prefix that is
one of the system paths (like '/usr') the module files that are
generated will prepend '/usr/bin' to 'PATH', etc. This is particularly
nasty at the time when a module file is unloaded, and e.g. paths like
'/usr/bin' will be discarded from PATH.
This PR solves the issue skipping system paths when a prefix inspection
is made to generate module files.
* Module files now are generated using a template engine refers #2902#3173
jinja2 has been hooked into Spack.
The python module `modules.py` has been splitted into several modules
under the python package `spack/modules`. Unit tests stressing module
file generation have been refactored accordingly.
The module file generator for Lmod has been extended to multi-providers
and deeper hierarchies.
* Improved the support for templates in module files.
Added an entry in `config.yaml` (`template_dirs`) to list all the
directories where Spack could find templates for `jinja2`.
Module file generators have a simple override mechanism to override
template selection ('modules.yaml' beats 'package.py' beats 'default').
* Added jinja2 and MarkupSafe to vendored packages.
* Spec.concretize() sets mutual spec-package references
The correct place to set the mutual references between spec and package
objects at the end of concretization. After a call to concretize we
should now be ensured that spec is the same object as spec.package.spec.
Code in `build_environment.py` that was performing the same operation
has been turned into an assertion to be defensive on the new behavior.
* Improved code and data layout for modules and related tests.
Common fixtures related to module file generation have been extracted
in `conftest.py`. All the mock configurations for module files have been
extracted from python code and have been put into their own yaml file.
Added a `context_property` decorator for the template engine, to make
it easy to define dictionaries out of properties.
The default for `verbose` in `modules.yaml` is now False instead of True.
* Extendable module file contexts + short description from docstring
The contexts that are used in conjunction with `jinja2` templates to
generate module files can now be extended from package.py and
modules.yaml.
Module files generators now infer the short description from package.py
docstring (and as you may expect it's the first paragraph)
* 'module refresh' regenerates all modules by default
`module refresh` without `--module-type` specified tries to
regenerate all known module types. The same holds true for `module rm`
Configure options used at build time are extracted and written into the
module files where possible.
* Fixed python3 compatibility, tests for Lmod and Tcl.
Added test for exceptional paths of execution when generating Lmod
module files.
Fixed a few compatibility issues with python3.
Fixed a bug in Tcl with naming_scheme and autoload + unit tests
* Updated module file tutorial docs. Fixed a few typos in docstrings.
The reference section for module files has been reorganized. The idea is
to have only three topics at the highest level:
- shell support + spack load/unload use/unuse
- module file generation (a.k.a. APIs + modules.yaml)
- module file maintenance (spack module refresh/rm)
Module file generation will cover the entries in modules.yaml
Also:
- Licenses have been updated to include NOTICE and extended to 2017
- docstrings have been reformatted according to Google style
* Removed redundant arguments to RPackage and WafPackage.
All the callbacks in `RPackage` and `WafPackage` that are not build
phases have been modified not to accept a `spec` and a `prefix`
argument. This permits to leverage the common `configure_args` signature
to insert by default the configuration arguments into the generated
module files. I think it's preferable to handling those packages
differently than `AutotoolsPackage`. Besides only one package seems
to override one of these methods.
* Fixed broken indentation + improved resiliency of refresh
Fixed broken indentation in `spack module refresh` (probably a rebase
gone silently wrong?). Filter the writers for blacklisted specs before
searching for name clashes. An error with a single writer will not
stop regeneration, but instead will print a warning and continue
the command.
- converted `log_path` and `env_path` to properties of PackageBase.
- InstallErrors in build_environment are now annotated with the package
that caused them, in the 'pkg' attribute.
- Add `--show-log-on-error` option to `spack install` that catches
InstallErrors and prints the log to stderr if it exists.
Note that adding a reference to the Pakcage allows a lot of stuff
currently handled by do_install() and build_environment to be handled
externally.
- '\b' in regular expression needs to be in a raw string (r'\b')
- Regression test that would've caught this was unintentionally disabled
- This fixes the string and the test
The correct place to set the mutual references between spec and
package objects is at the end of concretization. After a call to
concretize we should now be ensured that spec is the same object
as spec.package.spec.
Code in `build_environment.py` that was performing the same
operation has been turned into an assertion to be defensive on
the new behavior.
- Fixes bugs where concretization would fail due to an erroneously cached
_concrete attribute.
- Ripped out a bunch of code in spec.py that isn't needed/valid anymore:
- The various concrete() methods on different types of Specs would
attempt to statically compute whether the Spec was concrete.
- This dates back to when DAGs were simpler and there were no optional
dependencies. It's actually NOT possible to compute statically
whether a Spec is concrete now. The ONLY way you know is if it goes
through concretization and is marked concrete once that completes.
- This commit removes all simple concreteness checks and relies only on
the _concrete attribute. This should make thinking about
concreteness simpler.
- Fixed a couple places where Specs need to be marked concrete explicitly.
- Specs read from files and Specs that are destructively copied from
concrete Specs now need to be marked concrete explicitly.
- These spots may previously have "worked", but they were brittle and
should be explcitly marked anyway.
- Dependencies in concrete specs did not previously have their cache
fields (_concrete, _normal, etc.) preserved.
- _dup and _dup_deps weren't passing each other enough information to
preserve concreteness properly, so only the root was properly
preserved.
- cached concreteness is now preserved properly for the entire DAG, not
just the root.
- added method docs.
Fixes#4112
This commit extends the support of the AutotoolsPackage methods
`with_or_without` and `enable_or_disable` to bool-valued variants. It
also defines for those functions a convenience short-cut if the
activation parameter is the prefix of a spec (like in
`--with-{pkg}={prefix}`).
This commit also includes:
* Updates to viennarna and adios accordingly: they have been modified to
use `enable_or_disable` and `with_or_without`
* Improved docstrings in `autotools.py`. Raise `KeyError` if name is
not a variant.
Renames the existing bootstrap command to 'clone'. Repurposes
'spack bootstrap' to install packages that are useful to the
operation of Spack (for now this is just environment-modules).
For bash and ksh users running setup-env.sh, if a Spack-installed
instance of environment-modules is detected and environment modules
and dotkit are not externally available, Spack will define the
'module' command in the user's shell to use the environment-modules
built by Spack.
First, quote the environment variable values. Second, export the
variables. sorry, this is bourn-shell syntax. Happy to consider a
shell-independent way to do this, but spack is already using sh-like
"env=value"
* Added support to query packages by tags.
- The querying commands `spack list`, `spack find` and `spack info` have
been modified to support querying by tags. Tests have been added to
check that the feature is working correctly under what should be the
most frequent use cases.
* Refactored Repo class to make insertion of new file caches easier.
- Added the class FastPackageChecker. This class is a Mapping from
package names to stat info, that gets memoized for faster access.
- Extracted the creation of a ProviderIndex to its own factory function.
* Added a cache file for tags.
- Following what was done for providers, a TagIndex class has been added.
This class can serialize and deserialize objects from json. Repo and
RepoPath have a new method 'packages_with_tags', that uses the TagIndex
to compute a list of package names that have all the tags passed as
arguments.
On Ubuntu 14.04 the effect if the cache reduces the time for spack list
from ~3sec. to ~0.3sec. after the cache has been built.
* Fixed colorization of `spack info`
This command broke after #5109. It was using the default value for the
"dirty" argument in `setup_package`. Now it adopts the same logic as
in `spack install`. Changed help for '--clean' and '--dirty'.
Improved coverage of spack env.
The private method `Spec._dup` was missing a line (when setting compiler
flags the parent spec was not set to `self`). This resulted in
an inconsistent state of the duplicated Spec. This problem has been
fixed here. The docstring of `Spec._dup` has been updated.
This change is done to avoid inconsistencies during refactoring. The rationale is that functions at different levels in the call stack all define a default for the 'dirty' argument. This PR removes the default value for all the functions except the top-level one (`PackageBase.do_install`).
In this way not defining 'dirty' will result in an error, instead of the default value being used. This will reduce the risk of having an inconsistent behavior after a refactoring.
* Respect --insecure when fetching list_url.
* Ensure support for Python 2.6, and that urlopen works for python versions prior 2.7.9 and between 3.0 and 3.4.3.
* Simplified Spec.__init__ signature by removing the *dep_like argument.
The `*dep_like` argument of `Spec.__init__` is used only for tests. This
PR removes it from the call signature and introduces an equivalent
fixture to be used in tests.
* Refactored ``spec_from_dict`` to be a static method of ``Spec``
The fixture ``spec_from_dict`` has been refactored to be a static method
of ``Spec``. Test code has been updated accordingly. Added tests for
exceptional paths.
* Renamed argument `unique` to `normal` + added LazySpecCache class
As requested in the review the argument `unique` of `Spec.from_literal`
has been renamed to `normal`. To avoid eager evaluations of
`Spec(spec_like)` expressions a subclass of `collections.defaultdict`
has been introduced.
* Spec object can be keys of the dictionary for a spec literal.
Added back the possibility use a spec directly as a key. This permits
to build DAGs that are partially normalized.
- Update handling of ChildError so that its output is capturable from a
SpackCommand
- Update cmd/install test to make sure Python and build log output is
being displayed properly.
- install and probably other commands were designed to run once, but now
we can to test them from within Spack with SpackCommand
- cmd/install.py assumed that it could modify do_install in PackageBase
and leave it that way; this makes the decorator temporary
- package.py didn't properly initialize its stage if the same package had
been built successfully before (and the stage removed).
- manage stage lifecycle better and remember when Package needs to
re-create the stage
- If a failure comes from an external command and NOT the Python code,
display errors highlighted with some context.
- Add some rudimentary support for parsing errors out of the build log
(not very sophisticated yet).
- Build errors in Python code will still display with Python context.
Users can now add an optional custom message to the conflicts directive.
Layout on screen has been changed to improve readability and the long
spec is shown in tree format. Two conflicts in `espresso` have been
modified to showcase the feature.
- Python I/O would not properly interleave (or appear) with output from
subcommands.
- Add a flusing wrapper around sys.stdout and sys.stderr when
redirecting, so that Python output is synchronous with that of
subcommands.
- 'v' toggle was previously only good for the current install.
- subsequent installs needed user to press 'v' again.
- 'v' state is now preserved across dependency installs.
- Previously we would use `os._exit()` in to avoid Spack error handling
in the parent process when build processes failed. This isn't
necessary anymore since build processes propagate their exceptions to
the parent process.
- Use `sys.exit` instead of `os._exit`. This has the advantage of
automatically flushing output streams on quit, so output from child
processes is not lost when Spack exits.
- Simplify interface to log_output. New interface requires only one
context handler instead of two. Before:
with log_output('logfile.txt') as log_redirection:
with log_redirection:
# do things ... output will be logged
After:
with log_output('logfile.txt'):
# do things ... output will be logged
If you also want the output to be echoed to ``stdout``, use the
`echo` parameter::
with log_output('logfile.txt', echo=True):
# do things ... output will be logged and printed out
And, if you just want to echo *some* stuff from the parent, use
``force_echo``:
with log_output('logfile.txt', echo=False) as logger:
# do things ... output will be logged
with logger.force_echo():
# things here will be echoed *and* logged
A key difference between this and the previous implementation is that
*everything* in the context handler is logged. Previously, things like
`Executing phase 'configure'` would not be logged, only output to the
screen, so understanding phases in the build log was difficult.
- The implementation of `log_output()` is different in two major ways:
1. This implementation avoids race cases by using only one pipe (before
we had a multiprocessing pipe and a unix pipe). The logger daemon
stops naturally when the input stream is closed, which avoids a race
in the previous implementation where we'd miss some lines of output
because the parent would shut the daemon down before it was done
with all output.
2. Instead of turning output redirection on and off, which prevented
some things from being logged, this version uses control characters
in the output stream to enable/disable forced echoing. We're using
the time-honored xon and xoff codes, which tell the daemon to echo
anything between them AND write it to the log. This is how
`logger.force_echo()` works.
- Fix places where output could get stuck in buffers by flushing more
aggressively. This makes the output printed to the terminal the same
as that which would be printed through a pipe to `cat` or to a file.
Previously these could be weirdly different, and some output would be
missing when redirecting Spack to a file or pipe.
- Simplify input and color handling in both `build_environment.fork()`
and `llnl.util.tty.log.log_output()`. Neither requires an input_stream
parameter anymore; we assume stdin will be forwarded if possible.
- remove `llnl.util.lang.duplicate_stream()` and remove associated
monkey-patching in tests, as these aren't needed if you just check
whether stdin is a tty and has a fileno attribute.
- Fix issue with color formatting regular expression.
- _separators regex in spec.py could be constructed such that '^' came
first in the character matcher, e.g. '[^@#/]'. This inverts the match
and causes transient KeyErrors.
- Fixed to escape all characters in the constructed regex.
- This bug comes up in Python3 due to its more randomized hash iteration
order, but it could probably also happen in a Python 2 implementation.
- also clean up variable docstrings in spec.py
- Mac OS X Sierra has no /usr/include by default
- Instead of assuming there's an include directory in /usr, mock up a directory that looks like we expect.
This adds sbang hook support for node-js and fixes the sbang filter
for lua (the character class exclusion was swallowing newlines and
reporting a false positive if lua was mentioned anywhere in the
file).
* Docs: Travis-CI Workflow
Add a workflow how to use spack on Travis-CI.
Future Work:
depending if and how we can simplify 5101:
add a multi-compiler, multi-C++-standard, multi-software
build matrix example
* Fix Typos
* Colorize spack info. Adds prominence to preferred version. fixes#2708
This uses 'llnl.util.tty.color' to colorize the output of 'spack info'.
It also displays versions in the order the concretizer would choose
them and shows the preferred in a line on its own and in bold.
* Modified output according to Adam and Denis reviews.
Section titles are not bold + black, but bold + blue. Added a new
section named "Preferred version", which prints the preferred version
in bold characters.
* Further modifications according to Adam and Denis reviews.
After "Homepage:" we now have a single space. Removed newline after each
variant. Preferred version is not in bold fonts anymore. Added a simple
test that just runs the command.
* Improved error message for unsatisfiable specs. fixes#5066
This PR improves the error message for unsatisfiable specs by showing in tree format both the spec that cannot satisfy the constraint and the spec that asked for that constraint. After that follows a readable error message.
This PR allows additional unused properties at the top-level of the config.yaml file. Having these properties permits to use two different versions of Spack, one of which adds a new property, without receiving error messages due to the presence of this new property in a configuration cache stored in the user's home.
This fixes a syntax error in the index.html file generated by the
"spack buildcache" command when creating build caches. This also
fixes support for installing unsigned binaries.

* It is not possible to build with MKL, GCC, and OpenMP at this time
* Found a workaround for locating GCC libraries
* Typos and variable names
* Fix initialization of empty LibraryList
Adds the "buildcache" command to spack. The buildcache command is
used to create gpg signatures for archives of installed spack
packages; the signatures and archives are placed together in a
directory that can be added to a spack mirror. A user can retrieve
the archives from a mirror and verify their integrity using the
buildcache command. It is often the case that the user's Spack
instance is located in a different path compared to the Spack
instance used to generate the package archive and signature, so
this includes logic to relocate the RPATHs generated by Spack.
The action `CleanOrDirtyAction` has been added. It sets the default
value for `dest` to `spack.dirty`, and changes it according to the flags
passed via command line. Added unit tests to check that the arguments
are parsed correctly. Removed lines in `PackageBase` that were setting
the default value of dirty according to what was in the configuration.
Popen.communicate outputs a str object for python2 and a bytes
object for python3. This updates the Executable.__call__ function
to call .decode on the output of Popen.communicate only for python3.
This ensures that Executable.__call__ returns a str for python2 and
python3.

When a package is defined in more than one repository,
RepoPath.dirname_for_package_name may return the path
to either definition. This sidesteps that ambiguity by
accessing the module associated with the package definition.
* Merged 'purge' command with 'clean'. Deleted 'purge'. fixes#2942
'spack purge' has been merged with 'spack clean'. Documentation has been
updated accordingly. The 'clean' and 'purge' behavior are not mutually
exclusive, and they log brief information to tty while they go.
* Fixed a wrong reference to spack clean in the docs
* Added tests for 'spack clean'. Updated bash completion.
* Typo fixes in docstrings.
* Let OS classes know if the paths they get were explicitly specified by user.
* Fixed regexp for cray compiler version matching.
* Replaced LinuxDistro with CrayFrontend for the Cray platform's frontend.
Fixes#4898
Constraints that were supposed to be conditionally activated for
specified values of a single-valued variant were being activated
unconditionally in the case that the variant was associated with
an implicit dependency. For example if X->Y->Z and Y places a
conditional constraint on Z for a given single-valued variant on
Y, then it would have been applied unconditionally when
concretizing X.
* Add a QMakePackage base class
* Fix sqlite linking bug in qt-creator
* Add latest version of qt-creator
* Add latest version of qwt
* Use raw strings for regular expressions
* Increase minimum required version of qt
* Add comment about specific version of sqlite required
* Fixes for latest version of qwt and qt-creator
* Older versions of Qwt only work with older versions of Qt
* Fix crashes when running spack install under nohup
Fixes#4919
For reasons that I do not entire understand, duplicate_stream() throws
an '[Errno 22] Invalid argument' exception when it tries to
`os.fdopen()` the duplicated file descriptor generated by
`os.dup(original.fileno())`. See spack/llnl/util/lang.py, line
394-ish.
This happens when run under `nohup`, which supposedly has hooked
`stdin` to `/dev/null`.
It seems like opening and using `devnull` on the `input_stream` in
this situation is a reasonable way to handle the problem.
* Be more specific about error being handled.
Only catch the specific error that happens when trying to dup
the stdin that nohup provides.
Catching e as a StandardErorr and then
`type(e).__name__` tells me that it's an OSError.
Printing e.errno tells me that it's 22
Double checking tells me that 22 is EINVAL.
Phew.
- Remove `special_types` dict in spec.py, as only 'all' is still used
- Still allow 'all' to be used as a deptype
- Simplify `canonical_deptype` function
- Clean up args in spack graph
- Add tests
For packages which contain a mix of versions with formats X.Y and
X.Y.Z, if the user entered an X.Y version as a preference in
packages.yaml, Spack would get confused and favor any version A.B.Z
where X=A and Y=B. In the case where there is a mix of these version
types, this commit updates preferences so Spack will favor an exact
match.

Adds SpackCommand class allowing Spack commands to be easily in Python
Example usage:
from spack.main import SpackCommand
info = SpackCommand('info')
out, err = info('mpich')
print(info.returncode)
This allows easier testing of Spack commands.
Also:
* Simplify command tests
* Simplify mocking in command tests.
* Simplify module command test
* Simplify python command test
* Simplify uninstall command test
* Simplify url command test
* SpackCommand uses more compatible output redirection
* Initial work on flag trapping using functions called <flag>_handler and default_flag_handler
* Update packages so they do not obliterate flags
* Added append to EnvironmentModifications class
* changed EnvironmentModifications to have append_flags method
* changed flag_val to be a tuple
* Increased test coverage
* added documentation of flag handling
* Change path to CMakeLists.txt to be relative to root, not pwd
* Changes requested during code review
* Revert back to old naming of root_cmakelists_dir
* Make relative directory more clear in docs
* Revert change causing build_type AttributeError
* Fix forgotten abs_path var
* Update CLHEP with new relative path
* Update more packages with new root_cmakelists_dir syntax
- Lock test can be run either as a node-local test or as an MPI test.
- Lock test is now parametrized by filesystem, so you can test the
locking capabilities of your NFS, Lustre, or GPFS filesystem. See docs
for details.
* mv variants: packages are now needed only during normalization
The relationship among different types of variants have been weakened,
in the sense that now it is permitted to compare MV, SV and BV among
each other. The mechanism that permits this is an implicit conversion
of the variant passed as argument to the type of the variant asking
to execute a constrain, satisfies, etc. operation.
* asbtract variant: added a new type of variant
An abstract variant is like a multi valued variant, but behaves
differently on "satisfies" requests, because it will reply "True"
to requests that **it could** satisfy eventually.
Tests have been modified to reflect the fact that abstract variants
are now what get parsed from expressions like `foo=bar` given by users.
* Removed 'concrete=' and 'normal=' kwargs from Spec.__init__
These two keyword arguments where only used in one test module to force
a Spec to 'appear' concrete. I suspect they are just a leftover from
another refactoring, as now there's the private method '_mark_concrete'
that does essentially the same job. Removed them to reduce a bit the
clutter in Spec.
* Moved yaml related functions from MultiValuedVariant to AbstractVariant.
This is to fix the erros that are occurring in epfl-scitas#73, and that
I can't reproduce locally.
* Parse modules in a way that works for both lmod and tcl
* added test and made method more robust
* refactoring for pythonic clarity
* Improved detection of 'module' shell function + refactored module utilities into spack.util.module_cmd
* Improved regex to reject nested parentheses we are not prepared to handle
* make tests backwards compatible with python 2.6
* Improved regex to account for sh being aliased to bash and used in bash module definition on some systems
* Improve test compatibility with lmod
* Added error for None module_cmd
* Add test for get_module_cmd_from_which()
Add test for get_module_cmd_from_which().
Add -c argument to Popen call to typeset -f module in get_module_cmd_from_bash().
* Increased detection options
Included BASH_FUNC_module() variable outside of typeset as a detection option
This should work on bash even in restricted_shell mode
Kept the typeset detection as an option in case the module function is not exported in bash
Also added try statements to tests, with environment recreation in finally blocks.
* More tests added; some hackiness
* increased test coverage for util/module_cmd
* Code changes to enable system config scope in /etc
Files will go in either /etc/spack or /etc/spack/<platform>
Required minor changes to conftest.
* Updated documentation to match new config scope
- previous code called `which` on $EDITOR, but that doesn't work for
EDITORs like `emacs -nw` or `emacsclient -t -nw`.
- This patch just trusts EDITOR if it is set (same as previous
behavior), and only uses the defaults if it's not.
* issue 4492: added xfailing test, added owner to DependencyMap
* DependencyMap.concrete checks if we have unconditional dependencies
This fixes#4492 and #4107 using some heuristics to avoid an infinite
recursion among Spec.satisfies, Spec.concrete and DependencyMap.concrete
The idea, as suggested by @becker33, is to check just for unconditional
dependencies. This is not covering the whole space and a package with
just conditional dependencies can still fail in the same way. It should
cover though all the **real** packages we have in our repo so far.
* Check for CRAYPE_VERSION instead of path
Architecture tests would fail on Cray since it would not find
the expected path. To make the test correctly work on Cray search
for the CRAYPE version instead.
* Catch SystemExit error in case flake8 not in path
On shared systems having flake8 can involve starting own virtual env.
Skip the test if no flake8 is found to avoid failure reporting.
* Add compatibility to 1.5 svnadmin create
The flag added is needed to correctly create svn repos on NERSC systems.
This could be unnecessary for other sites. I'd like to see others
test before this change gets merged.
- Skip spack flake8 test when flake8 is not installed.
- Fix parsing of dashes in specs broken by new help parser.
- use argparse.REMAINDER instead of narg='?'
- don't interpret parts of specs like -mpi as arguments.
* Initial version of the namd package
* Modified charm to consider compile against intel/intel-mpi
* Correction of namd to compile with intel-mkl and intel compiler
* Adding inclue64 in the prefix
* adding property for the build directory
* removing useless function build
* During install, remove prior unfinished installs
If a user performs an installation which fails, in some cases the
install prefix is still present, and the stage path may also be
present. With this commit, unless the user specifies
'--keep-prefix', installs are guaranteed to begin with a clean
slate. The database is used to decide whether an install finished,
since a database record is not added until the end of the install
process.
* test updates
* repair_partial uses keep_prefix and keep_stage
* use of mock stage object to ensure that stage is destroyed when it should be destroyed (and otherwise not)
* add --restage option to 'install' command; when this option is not set, the default is to reuse a stage if it is found.
- Add a `spack gpg` subcommand in anticipation of signed binaries.
- GPG keys are stored in var/spack/gpg, and the spack gpg command manages them.
- Docs are included on the command.
* Touch up string expansion.
I'm chasing this:
```
$ (module purge; spack install perl %gcc/5.4.0)
==> Error: No installed spec matches the hash: '%s'
```
There's something deeper going on, but the error message isn't helpful.
After this change it tells me this:
```
$ (module purge; spack install perl %gcc/5.4.0)
==> Error: No installed spec matches the hash: '5.4.0'
```
Which is weird because `5.4.0` is not a hash... Whatever is going on here, the error message needs to be fixed.
* Flake8 whitespace
* fix parser
* Removed xfails
* cleaned up debug print statements
* make use of these changes in gcc
* Added comment explaining unreachable line, line left for added protection
* Sphinx no longer supports Python 2.6
* Update vendored sphinxcontrib.programoutput from 0.9.0 to 0.10.0
* Documentation cannot be built in parallel
* Let Travis install programoutput for us
* Remove vendored sphinxcontrib-programoutput
Recent updates to the sphinx package prevent the vendored version
from being found in sys.path. We don't vendor sphinx, so it doesn't
make sense to vendor sphinxcontrib-programoutput either.
PR #3367 inadvertently changed the semantics of _find_recursive and
_find_non_recursive so that the returned list are not ordered as the
input search list. This commit restores the original semantic, and adds
tests to verify it.
Added DFLAGS to the `make.inc` file being written.
These macros are also added to the language specific variables
like CFLAGS, CXXFLAGS and FCFLAGS. Changed `spec.satisfies('foo')`
with `'foo' in spec` in `intel-mkl`, see #4135. Added a basic
build interface to `intel-mpi`.
It seems that parse_anonymous_spec may fail if more than one part
(variant, version range, etc.) is given to the function. Added tests to
code against to fix the problem in #4144.
- Full help is now only generated lazily, when needed.
- Executing specific commands doesn't require loading all of them.
- All commands are only loaded if we need them for help.
- There is now short and long help:
- short help (spack help) shows only basic spack options
- long help (spack help -a) shows all spack options
- Both divide help on commands into high-level sections
- Commands now specify attributes from which help is auto-generated:
- description: used in help to describe the command.
- section: help section
- level: short or long
- Clean up command descriptions
- Add a `spack docs` command to open full documentation
in the browser.
- move `spack doc` command to `spack pydoc` for clarity
- Add a `spack --spec` command to show documentation on
the spec syntax.
* SV variants are evaluated correctly in `when=` statements fixes#4113
The problem here was tricky:
```python
spec.satisfies(other)
```
changes already the MV variants in others into SV variants (where
necessary) if spec is concrete. If it is not concrete it does
nothing because we may be acting at a pure syntactical level.
When evaluating a `when=` keyword spec is for sure not concrete
as it is in the middle of the concretization process. In this case we
have to trigger manually the substitution in other to not end up
comparing a MV variant "foo=bar" to a SV variant "foo=bar" and having
False in return. Which is wrong.
* sv variants: improved error message for typos in "when=" statements
Modifications:
- added support for multi-valued variants
- refactored code related to variants into variant.py
- added new generic features to AutotoolsPackage that leverage multi-valued variants
- modified openmpi to use new features
- added unit tests for the new semantics
This allows people on systems that don't have all the fetchers to still
run Spack tests. Mark tests that require git, subversion, or mercurial to
be skipped if they're not installed.
* Filter all system paths introduced by dependencies from PATH
* Make sure path filtering works *even* for trailing slashes
* Revert some of the changes to `filter_system_paths`
* Yes, `bin64` is a real thing (sigh)
* add tests: /usr, /usr/, /usr/local/../bin, etc.
* Convert from rST to Google-style docstrings
The required hash of a submodule might point to the
non-HEAD commit of the current main branch and hence
would lead to a "no such remote ref" at checkout in
a shallow submodule.
## Motivation
Python installations are both important and unfortunately inconsistent. Depending on the Python version, OS, and the strength of the Earth's magnetic field when it was installed, the name of the Python executable, directory containing its libraries, library names, and the directory containing its headers can vary drastically.
I originally got into this mess with #3274, where I discovered that Boost could not be built with Python 3 because the executable is called `python3` and we were telling it to use `python`. I got deeper into this mess when I started hacking on #3140, where I discovered just how difficult it is to find the location and name of the Python libraries and headers.
Currently, half of the packages that depend on Python and need to know this information jump through hoops to determine the correct information. The other half are hard-coded to use `python`, `spec['python'].prefix.lib`, and `spec['python'].prefix.include`. Obviously, none of these packages would work for Python 3, and there's no reason to duplicate the effort. The Python package itself should contain all of the information necessary to use it properly. This is in line with the recent work by @alalazo and @davydden with respect to `spec['blas'].libs` and friends.
## Prefix
For most packages in Spack, we assume that the installation directory is `spec['python'].prefix`. This generally works for anything installed with Spack, but gets complicated when we include external packages. Python is a commonly used external package (it needs to be installed just to run Spack). If it was installed with Homebrew, `which python` would return `/usr/local/bin/python`, and most users would erroneously assume that `/usr/local` is the installation directory. If you peruse through #2173, you'll immediately see why this is not the case. Homebrew actually installs Python in `/usr/local/Cellar/python/2.7.12_2` and symlinks the executable to `/usr/local/bin/python`. `PYTHONHOME` (and presumably most things that need to know where Python is installed) needs to be set to the actual installation directory, not `/usr/local`.
Normally I would say, "sounds like user error, make sure to use the real installation directory in your `packages.yaml`". But I think we can make a special case for Python. That's what we decided in #2173 anyway. If we change our minds, I would be more than happy to simplify things.
To solve this problem, I created a `spec['python'].home` attribute that works the same way as `spec['python'].prefix` but queries Python to figure out where it was actually installed. @tgamblin Is there any way to overwrite `spec['python'].prefix`? I think it's currently immutable.
## Command
In general, Python 2 comes with both `python` and `python2` commands, while Python 3 only comes with a `python3` command. But this is up to the OS developers. For example, `/usr/bin/python` on Gentoo is actually Python 3. Worse yet, if someone is using an externally installed Python, all 3 commands may exist in the same directory! Here's what I'm thinking:
If the spec is for Python 3, try searching for the `python3` command.
If the spec is for Python 2, try searching for the `python2` command.
If neither are found, try searching for the `python` command.
## Libraries
Spack installs Python libraries in `spec['python'].prefix.lib`. Except on openSUSE 13, where it installs to `spec['python'].prefix.lib64` (see #2295 and #2253). On my CentOS 6 machine, the Python libraries are installed in `/usr/lib64`. Both need to work.
The libraries themselves change name depending on OS and Python version. For Python 2.7 on macOS, I'm seeing:
```
lib/libpython2.7.dylib
```
For Python 3.6 on CentOS 6, I'm seeing:
```
lib/libpython3.so
lib/libpython3.6m.so.1.0
lib/libpython3.6m.so -> lib/libpython3.6m.so.1.0
```
Notice the `m` after the version number. Yeah, that's a thing.
## Headers
In Python 2.7, I'm seeing:
```
include/python2.7/pyconfig.h
```
In Python 3.6, I'm seeing:
```
include/python3.6m/pyconfig.h
```
It looks like all Python 3 installations have this `m`. Tested with Python 3.2 and 3.6 on macOS and CentOS 6
Spack has really nice support for libraries (`find_libraries` and `LibraryList`), but nothing for headers. Fixed.
When a compiler was not found a stacktrace was displayed to user because
there were three arguments to be substituted in a string with only two
substitutions to be done.
Fixes#4026#1167 updated Database.reindex to keep old installation records to
support external packages. However, when a user manually removes a
prefix and reindexes this kept the records so the packages were
still installed according to "spack find" etc. This adds a check
for non-external packages to ensure they are properly installed
according to the directory layout.
- add Version.__format__ to support new-style formatting.
- Python3 doesn't handle this well -- it delegates to
object.__format__(), which raises an error for fancy format strings.
- not sure why it doesn't call str(self).__format__ instead, but that's
hwo things are.
* Properly ignore flake8 F811 redefinition errors
* Add unit tests for flake8 command
* Allow spack flake8 to work on systems with older git
* Skip flake8 unit tests for Python 2.6 and 3.3
* treats correctly a change from `explicit=False` to `explicit=True` in an external package DB entry.
* added unit tests
* fixed issues raised by @tgamblin . In particular the PR is no more hash-changing for packages that are not external.
* added a test to check correctness of a spec/yaml round-trip for things that involve an external
* Don't find external module path at each step of concretization
* it's not necessary.. The paths are retrieved at the end of concretizaion
* Don't find replacements for external packages.
* Test root of the DAG if external
* No reason not to test if the root of the DAG is external when external
packages are now first class citizens!
* Create `external` property for Spec (for external_path and external_module)
* Allow users to specify external package paths relative to spack
* Canonicalize external package paths so that users may specify their
locations relative to spack's directory.
* Update tests to use new external_path and external properly.
* skip license hooks on external
- Spack doesn't need eggs -- it manages its own directories
- Simplify install layout and reduce sys.path searches by installing all
packages flat (eggs are deprecated for wheels, and this is also what
wheels do).
- We now supply the --single-version-externally-managed argument to
`setup.py install` for setuptools packages and setuptools.
- modify packages to only use setuptools args if setuptools is an
immediate dependency
- Remove setuptools from packages that do not need it.
- Some packages use setuptools *only* when certain args (likeb
'develop' or 'bdist') are supplied to setup.py, and they specifically
do not use setuptools for installation.
- Spack never calls setup.py this way, so just removing the setuptools
dependency works for these packages.
* fetch git submodules recursively
This is useful if the submodules have submodules themselves. On
the other hand doing a recursive update doesn't hurt if there
is only one level.
* fetch submodules with depth=1 as well (fix#2190)
* use git submodule with depth only for git>=1.8.4
- Spack install would previously fail if it could not load a package for
the thing being uninstalled.
- This reworks uninstall to handle cases where the package is no longer
known, e.g.:
a) the package has been renamed or is no longer in Spack
b) the repository the package came from is no longer registered in
repos.yaml
- gcc on macOS says it's version 4.2.1, but it's really clang, and it's
actually the *same* clang as the system clang.
- It also doesn't respond with a full path when called with
--print-file-name=libstdc++.dylib, which is expected from gcc in abi.py.
Instead, it gives a relative path and _gcc_compiler_compare doesn't
understand what to do with it. This results in errors like:
```
lib/spack/spack/abi.py, line 71, in _gcc_get_libstdcxx_version
libpath = os.readlink(output.strip())
OSError: [Errno 2] No such file or directory: 'libstdc++.dylib'
```
- This commit does two things:
1. Ignore any gcc that's actually clang in abi.py. We can probably do
better than this, but it's not clear there is a need to, since we
should handle the compiler as clang, not gcc.
2. Don't auto-detect any "gcc" that is actually clang anymore. Ignore
it and expect people to use clang (which is the default macOS
compiler anyway).
Users can still add fake gccs to their compilers.yaml if they want, but
it's discouraged.
* Checksum code wasn't opening binary files as binary.
- Fixes Python 3 issue where files are opened as unicode text by default,
and decoding fails for binary blobs.
* Simplify fetch test parametrization.
* - add tests for URL fetching and checksumming.
- fix coverage on interface functions in FetchStrategy superclass
- add some extra crypto tests.
* Package install remove prior unfinished installs
Depending on how spack is terminated in the middle of building a
package it may leave a partially installed package in the install
prefix. Originally Spack treated the package as being installed if
the prefix was present, in which case the user would have to
manually remove the installation prefix before restarting an
install. This commit adds a more thorough check to ensure that a
package is actually installed. If the installation prefix is present
but Spack determines that the install did not complete, it removes
the installation prefix and starts a new install; if the user has
enabled --keep-prefix, then Spack reverts to its old behavior.
* Added test for partial install handling
* Added test for restoring DB
* Style fixes
* Restoring 2.6 compatibility
* Relocated repair logic to separate function
* If --keep-prefix is set, package installs will continue an install from an existing prefix if one is present
* check metadata consistency when continuing partial install
* Added --force option to make spack reinstall a package (and all dependencies) from scratch
* Updated bash completion; removed '-f' shorthand for '--force' for install command
* dont use multiple write modes for completion file
* Add tests to mercurial package
* Add support for --insecure with mercurial fetching
* Install man pages and tab-completion scripts
* Add tests and latest version for all deps
* Flake8 fix
* Use certifi module to find CA certificate
* Flake8 fix
* Unset PYTHONPATH when running hg
* svn_fetch should use to svn-test, not hg-test
* Drop Python 3 support in Mercurial
Python 3 support is a work in progress and isn't currently
recommended:
https://www.mercurial-scm.org/wiki/SupportedPythonVersions
* Test both secure and insecure hg fetching
* Test both secure and insecure git and svn fetching
`set_executable` now checks if a user/group.other had read permission
on a file and if it does then it sets the corresponding executable
bit.
