Fixed#15884.
Spack asks every package linked into an environment to tell us how
environment variables should be modified when a spack environment is
activated. As part of this, specs in an environment are symlinked into
the environment's view (see #13249), and the package calculates
environment modifications with *the default view as the prefix*.
All of this works nicely for pointing the user's environment at the view
*if* every package is successfully linked. Unfortunately, right now we
only track what specs "should" be in a view, not which specs actually
are. So we end up calculating environment modifications on things that
aren't linked into thee view, and the exception isn't caught, so lots of
spack commands end up failing.
This fixes the issue by ignoring and warning about specs where
calculating environment modifications fails. So we can still keep using
Spack even if the current environment is incomplete.
We should probably also just avoid computing env modifications *entirely*
for unlinked packages, but right now that is a slow operation (requires a
lot of YAML parsing). We should revisit that when we have some better
state management for views, but the fix adopted here will still be
necessary, as we want spack commands to be resilient to other types of
bugs in `setup_run_environment()` and friends. That code is in packages
and we have to assume it could be buggy when we call it outside of builds
(as it might fail more than just the build).
`spack test` has a spurious '[+] ' in the output:
```
lib/spack/spack/test/install.py .........[+] ......
```
Output is properly suppressed:
```
lib/spack/spack/test/install.py ...............
```
Makes the following changes:
* (Fixes#15620) tty configuration was failing when stdout was
redirected. The implementation now creates a pseudo terminal for
stdin and checks stdout properly, so redirections of stdin/out/err
should be handled now.
* Handles terminal configuration when the Spack process moves between
the foreground and background (possibly multiple times) during a
build.
* Spack adjusts terminal settings to allow users to to enable/disable
build process output to the terminal using a "v" toggle, abnormal
exit cases (like CTRL-C) could leave the terminal in an unusable
state. This is addressed here with a special-case handler which
restores terminal settings.
Significantly extend testing of process output logger:
* New PseudoShell object for setting up a master and child process
and configuring file descriptor inheritance between the two
* Tests for "v" verbosity toggle making use of the added PseudoShell
object
* Added `uniq` function which takes a list of elements and replaces
any consecutive sequence of duplicate elements with a single
instance (e.g. "112211" -> "121")

The performance improvements done in #14693 where leaving the DB in an inconsistent state when specs were removed from it. This PR updates the DB internal state whenever the DB is written to a file.
Note that we still cannot properly enumerate installed dependents, so there is a TODO in this code. Fixing that will require the dependents dictionaries in specs to be re-keyed (either by hash, or not keyed at all -- a list would do). See #11983 for details.
Reading the database repeatedly can be quite slow. We need a way to speed
up Spack when it reads the DB multiple times, but the DB has not been
modified between reads (which is nearly all the time).
- [x] Add a file containing a unique uuid that is regenerated at database
write time. Use this uuid to suppress re-parsing the database
contents if we know a previous uuid and the uuid has not changed.
- [x] Fix mutable_database fixture so that it resets the last seen
verifier when it resets.
- [x] Enable not rereading the database immediately after a write. Make
the tests reset the last seen verifier in between tests that use the
database fixture.
- [x] make presence of uuid module optional
Removed the code that was converting the old index.yaml format into
index.json. Since the change happened in #2189 it should be
considered safe to drop this (untested) code.
If a user invoked "spack env activate example-henv", Spack would
mistakenly interpret the "-h" from "example-henv" as the "-h" option.
This commit allows users to create and activate environments with
"-h" in the name.
This issue existed for bash shell support as well as csh support, and
this commit addresses both, along with some other unrelated csh
support issues.
* only override spec prefix for non-external packages
* add test that environment shell modifications respect explicitly-specified prefixes for external packages
* add clarifying comment
spack.util.environment_after_sourcing_files compares the local
environment against a shell environment after having sourced a
file; but this ends up including the default shell profile and
rc, which might differ from the local environment.
To change this, compare against the default shell environment,
expressed here as 'source /dev/null'.
Spack currently cannot run as a background process uninterrupted because some of the logging functions used in the install method (especially to create the dynamic verbosity toggle with the v key) cause the OS to issue a SIGTTOU to Spack when it's backgrounded.
This PR puts the necessary gatekeeping in place so that Spack doesn't do anything that will cause a signal to stop the process when operating as a background process.
Bug: Spack hangs on some Cray machines
Reason: The TERM environment variable is necessary to run bash -lc "echo $CRAY_CPU_TARGET", but we run that command within env -i, which wipes the environment.
Fix: Manually forward the TERM environment variable to env -i /bin/bash -lc "echo $CRAY_CPU_TARGET"
When trying to use an upstream Spack repository, as of f2aca86 Spack
was attempting to write to the upstream DB based on a new metadata
directory added in that commit. Upstream DBs are read-only, so this
should not occur.
This adds a check to prevent Spack from writing to the upstream DB
fixes#15449
Before this PR a call to pkg.url_for_version was modifying
class attributes determining different results for subsequents
calls and an error when the urls was empty.
This recovers the old behavior of replace_prefix_bin that was
modified to work with elf binaries by prefixing os.sep to new prefix
until length is the same as old prefix.
Testing the install StopIteration exception resulted in an attribute error:
AttributeError: 'StopIteration' object has no attribute 'message'
This PR adds a unit test and resolves that error.
The new build process, introduced in #13100 , relies on a spec's dependents in addition to their dependencies. Loading a spec from a yaml file was not initializing the dependents.
- [x] populate dependents when loading from yaml
The distributed build PR (#13100) -- did not check the install status of dependencies when using the `--only package` option so would refuse to install a package with the claim that it had uninstalled dependencies whether that was the case or not.
- [x] add install status checks for the `--only package` case.
- [x] add initial set of tests
This change stores packages' configure arguments during build and makes
use of them while refreshing module files. This fixes problems such as in
#10716.
