2020-04-29Spack command extensions: error-handling (#13635)Chris Green5-85/+332
Generally speaking, errors that are encountered when attempting to load command extensions now terminate the running Spack instance. * Added new exceptions `spack.cmd.PythonNameError` and `spack.cmd.CommandNameError`. * New functions `spack.cmd.require_python_name(pname)` and `spack.cmd.require_cmd_name(cname)` check that `pname` and `cname` respectively meet requirements, throwing the appropriate error if not. * `spack.cmd.get_module()` uses `require_cmd_name()` and passes through exceptions from module load attempts. * `spack.cmd.get_command()` uses `require_cmd_name()` and invokes `get_module()` with the correct command-name form rather than the previous (incorrect) Python name. * Added New exceptions `spack.extensions.CommandNotFoundError` and `spack.extensions.ExtensionNamingError`. * `_extension_regexp` has a new leading underscore to indicate expected privacy. * `spack.extensions.extension_name()` raises an `ExtensionNamingError` rather than using `tty.warn()`. * `spack.extensions.load_command_extension()` checks command source existence early and bails out if missing. Also, exceptions raised by `load_module_from_file()` are passed through. * `spack.extensions.get_module()` raises `CommandNotFoundError` as appropriate. * Spack `main()` allows `parser.add_command()` exceptions to cause program end. Tests: * More common boilerplate has been pulled out into fixtures including `sys.modules` dictionary cleanup and resource-managed creation of a simple command extension with specified contents in the source file for a single named command. * "Hello, World!" test now uses a command named `hello-world` instead of `hello` in order to verify correct handling of commands with hyphens. * New tests for: * Missing (or misnamed) command. * Badly-named extension. * Verification that errors encountered during import of a command are propagated upward.

2020-04-27Improve the coverage of spack.relocate (#15654)Massimiliano Culpo3-76/+148
This PR introduces trivial refactoring in: - `get_existing_elf_rpaths` - `get_relative_elf_rpaths` - `get_normalized_elf_rpaths` - `set_placeholder` mainly to be more consistent with practices used in other parts of the code and to simplify functions locally. It also adds or reworks unit tests for these functions and extends their docstrings. Co-authored-by: Patrick Gartung <gartung@fnal.gov> Co-authored-by: Peter J. Scheibel <scheibel1@llnl.gov>

2020-04-23tests: each mock package now has its own class (#16157)Todd Gamblin9-153/+279
Packages in Spack are classes, and we need to be able to execute class methods on mock packages. The previous design used instances of a single MockPackage class; this version gives each package its own class that can spider depenencies. This allows us to implement class methods like `possible_dependencies()` on mock packages. This design change moves mock package creation into the `MockPackageMultiRepo`, and mock packages now *must* be created from a repo. This is required for us to mock `possible_dependencies()`, which needs to be able to get dependency packages from the package repo. Changes include: * `MockPackage` is now `MockPackageBase` * `MockPackageBase` instances must now be created with `MockPackageMultiRepo.add_package()` * add `possible_dependencies()` method to `MockPackageBase` * refactor tests to use new code structure * move package mocking infrastructure into `spack.util.mock_package`, as it's becoming a more sophisticated class and it gets lots in `conftest.py`
2020-04-23spack info: allow variants section to be as wide as the terminal (#16254)Todd Gamblin1-9/+14
The variants table in `spack info` is cramped, as the *widest* it can be is 80 columns. And that's actually only sort of true -- the padding calculation is off, so it still wraps on terminals of size 80 because it comes out *slightly* wider. This change looks at the terminal size and calculates the width of the description column based on it. On larger terminals, the output looks much nicer, and on small terminals, the output no longer wraps. Here's an example for `spack info qmcpack` with 110 columns. Before: Name [Default] Allowed values Description ==================== ==================== ============================== afqmc [off] on, off Install with AFQMC support. NOTE that if used in combination with CUDA, only AFQMC will have CUDA. build_type [Release] Debug, Release, The build type to build RelWithDebInfo complex [off] on, off Build the complex (general twist/k-point) version cuda [off] on, off Build with CUDA After: Name [Default] Allowed values Description ==================== ==================== ======================================================== afqmc [off] on, off Install with AFQMC support.

2020-04-21compiler wrappers: don't override -isystem with -I (#16077)Andrew W Elble2-14/+102
If the Spack compiler wrapper encounters any "-isystem" option, then when adding include directories for Spack dependencies, Spack will use "-isystem" instead of "-I". This prevents Spack-generated "-I" options from overriding the "-isystem" options generated by the build system. To ensure that build-system "-isystem" directories are searched first, Spack places all of its inserted "-isystem" directories after. The new ordering of -isystem includes is: * -isystem from build system (not system directories) * -isystem from Spack * -isystem from build system (for directories like /usr/include) The prior order of "-I" arguments is preserved (although as of this commit Spack no longer generates -I if -isystem is detected): * -I from build system (not system directories) * -I from Spack (only if there are no "-isystem" options) * -I from build system (for directories like /usr/include)
2020-04-20autotools: remove FORCE_UNSAFE_CONFIGURE from docs, commands, code (#16145)Todd Gamblin2-11/+4
Since #16132, we've consolidated the setting of FORCE_UNSAFE_CONFIGURE to `autotools.py`, so we don't need to use it in packages like `coreutils`, in our commands, or in our container recipes. - [x] Remove FORCE_UNSAFE_CONFIGURE from packages - [x] Remove FORCE_UNSAFE_CONFIGURE from container recipes - [x] Remove FORCE_UNSAFE_CONFIGURE from `spack ci` command

2020-04-18autotools: set FORCE_UNSAFE_CONFIGURE to 1 in autotools.py (#16132)Diego Magdaleno1-0/+15
This commit sets the `FORCE_UNSAFE_CONFIGURE` environment variable to 1 in autotools builds. We see a lot of builds popping up and complaining about `FORCE_UNSAFE_CONFIGURE`. This behavior is not actually part of `autoconf` per se. It comes from this patch to `mknod.m4`, which is used by a lot of autoconf builds: * https://lists.gnu.org/archive/html/bug-gnulib/2010-07/msg00282.html Which originated from this problem that someone had on AIX: * https://lists.gnu.org/archive/html/bug-gnulib/2010-07/msg00279.html The gist of the problem seems to be that they want to check whether `mknod` can do something as root, but instead of checking whether they're running as root and using `su` or something to test this, they just made it harder to run `configure` as root. This seems very ad hoc and this is one of many checks that are run as root in `configure`. Many of them run before this check, so it's not clear that the `FORCE_UNSAFE_CONFIGURE` thing is even preventing bad things from happening. So: 1. This only happens in `autotools` builds, so we should go ahead and put it into `autotools.py` instead of in the global build environment, and 2. The variable does too little and provides a false sense of security in the first place, so we'll just disable it and avoid the nuisance. If we really feel strongly about this we can put some warnings in Spack about running as root, but at the top level, not in the middle of an already running script like `configure`.

2020-04-16macos: use DYLD_FALLBACK_LIBRARY_PATH instead of DYLD_LIBRARY_PATHTodd Gamblin3-2/+6
`DYLD_LIBRARY_PATH` can frequently break builtin macOS software when pointed at Spack libraries. This is because it takes *higher* precedence than the default library search paths, which are used by system software. `DYLD_FALLBACK_LIBRARY_PATH`, on the other hand, takes lower precedence. At first glance, this might seem bad, because the software installed by Spack in an environment needs to find *its* libraries, and it should not use the defaults. However, Spack's isntallations are always `RPATH`'d, so they do not have this problem. `DYLD_FALLBACK_LIBRARY_PATH` is thus useful for things built in an environment that need to use Spack's libraries, that don't set *their* RPATHs correctly for whatever reason. We now prefer it to `DYLD_LIBRARY_PATH` in modules and in environments because it helps a little bit, and it is much less intrusive.

2020-04-15`spack install` terminal output handling in foreground/background (#15723)Todd Gamblin7-224/+1155
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") Co-authored-by: Adam J.

2020-04-15database: maintain in-memory consistency on remove (#15777)Massimiliano Culpo2-1/+21
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.
2020-04-15performance: add a verification file to the database (#14693)Andrew W Elble3-3/+52
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
