A non-existent upstream should not be fatal: it could only mean it is
not deployed yet. In the meantime, it should not block the user to
rebuild anything it needs.
A warning is still emitted, to let the user decide if this is ok or not.

Fixes missing chgrp on symlinks in package installations, and errors on
symlinks referencing non-existent or non-writable locations.
Note: `os.chown(.., follow_symlinks=False)` is python3 only, but
`os.lchown` exists in both versions.

When an upstream is specified but the directory does not exist, don't
create the directory for it, it might not be yours.

Trying to compute `dag_hash()` or `package_hash()` on a concrete spec that doesn't have
a `_package_hash` attribute would attempt to recompute the package hash.
This most commonly manifests as a failed lookup of a namespace if you attempt to uninstall
or compute the hashes of packages in exsternal repositories that aren't registered, e.g.:
```console
> spack spec --json c/htno
==> Error: Unknown namespace: myrepo
```
While it wouldn't change the already-assigned `dag_hash` value, this behavior is
incorrect, since the package file for a previously concrete spec:
1. might have changed since concretization,
2. might not exist anymore, or
3. might just not be findable by Spack.
This PR ensures that the package hash can't be computed on older concrete specs. Instead
of calling `package_hash()` from within `to_node_dict()`, we now check for the `_package_hash`
attribute and only add the package_hash to the spec record if it's there.
This PR also handles the tricky semantics of computing `package_hash()` at concretization
time. We have to compute it *before* marking the spec concrete so that `to_node_dict` can
use it. But this means that the logic for `package_hash()` can't rely on `spec.concrete`,
as it is called *during* concretization. Instead of checking for concreteness, `package_hash()`
now checks `_patches_assigned()` to determine whether it should add them to the package
hash.
- [x] Add an assert to `package_hash()` so it can't be called on specs for which it
would be wrong.
- [x] Add an `_assign_hash()` method to handle tricky semantics of `package_hash`
and `dag_hash`.
- [x] Rework concretization to call `_assign_hash()` before and after marking specs
concrete.
- [x] Rework content hash part of package hash to check for `_patches_assigned()`
instead of `spec.concrete`.
- [x] regression test

Previously we sorted by hash values for `spack graph`, but changing hashes can make the
test brittle and the node order seem nondeterministic to users.
- [x] Sort nodes in `spack graph` by the default edge order, which takes into account
parent and child names as well as dependency types.
- [x] Update ASCII test output for new order.

handling (#30192)

The dependency check currently checks whether there are only build
dependencies left for a particular package. However, the database also
contains uninstalled packages, which can cause the check to fail.
For instance, with `bison` and `flex` having already been uninstalled,
`m4` will have the following dependents:
```
bison ('build', 'run')--> m4
flex ('build',)--> m4
libnl ('build',)--> m4
```
`bison` and `flex` should be ignored in this case because they are not
installed anymore.
Fixes #30673

#24556 merged in support for Python's .zip file support via ZipFile.
However as per #30200 ZipFile does not preserve file permissions of
the extracted contents. This PR returns to using the `unzip`
executable on non-Windows systems (as was the case before #24556)
and now uses `tar` on Windows to extract .zip files.

We previously had checks in `directory_layout` to check for build-dependency
conflicts when we weren't storing build dependencies. We don't need
those anymore; we can just rely on the DAG hash now that it includes everything
we know about each spec.
- [x] Remove vestigial code for checking installed spec against concrete spec
in `ensure_installed()`
- [x] Remove `SpecHashCollisionError` -- if specs have the same hash now, they're
the same as far as `DirectoryLayout` should be concerned.
- [x] Convert spec comparison to `dag_hash()` comparison when adding extensions.

The database now stores full hashes, so we need to adjust the criteria we use to
determine if something can be uninstalled. Specifically, it's ok to uninstall thing that
have remaining build-only dependents.
|
|
With the original DAG hash, we did not store build dependencies in the database, but
with the full DAG hash, we do. Previously, we'd never tell the concretizer about build
dependencies of things used by hash, because we never had them. Now, we have to avoid
telling the concretizer about them, or they'll unnecessarily constrain build
dependencies for new concretizations.
- [x] Make database track all dependencies included in the `dag_hash`
- [x] Modify spec_clauses so that build dependency information is optional
and off by default.
- [x] `spack diff` asks `spec_clauses` for build dependencies for completeness
- [x] Modify `concretize.lp` so that reuse optimization doesn't affect fresh
installations.
- [x] Modify concretizer setup so that it does *not* prioritize installed versions
over package versions. We don't need this with reuse, so they're low priority.
- [x] Fix `test_installed_deps` for full hash and new concretizer (does not work
for old concretizer with full hash -- leave this for later if we need it)
- [x] Move `test_installed_deps` mock packages to `builtin.mock` for easier debugging
with `spack -m`.
- [x] Fix `test_reuse_installed_packages_when_package_def_changes` for full hash
|
|
- [x] update test to use `build_hash` instead of `dag_hash`, as we're testing for
graph structure, and specifically NOT testing for package changes.
- [x] make hash descriptors callable on specs to simplify syntax for invoking them
- [x] make `Spec.spec_hash()` public

This removes all but one usage of runtime hash. The runtime hash was being used to write
historical lockfiles for tests, but we don't need it for that; we can just save those
lockfiles.
- [x] add legacy lockfiles for v1, v2, v3
- [x] fix bugs with v1 lockfile tests (the dummy lockfile we were writing was not actually
a v1 lockfile because it used the new spec file format).
- [x] remove all but one runtime_hash usage -- that one needs a small rework of the
concretizer to really fix, as it's about separate concretization of build
dependencies.
- [x] Document the history of the lockfile format in `environment/__init__.py`

Some test cases had to be modified in a kludgy way so that abstract specs made
concrete would have versions on them. We shouldn't *need* to do this, as the
only reason we care is because the content hash has to be able to get an archive
for a version.
This modifies the content hash so that it can be called on abstract specs,
including only relevant content.
This does NOT add a partial content hash to the DAG hash, as we do not really
want that -- we don't need in-memory spec hashes to need to load package files.
It just makes `Package.content_hash()` less prickly and tests easier to
understand.

`spack monitor` expects a field called `spec_full_hash`, so we shouldn't change that.
Instead, we can pass a `dag_hash` (which is now the full hash) but not change the field
name.

`hashes_final` was used to indicate when a spec was concrete but possibly lacked
`full_hash` or `build_hash` fields. This was only necessary because older Spacks
didn't generate them, and we want to avoid recomputing them, as we likely do not
have the same package files as existed at concretization time.
Now, we don't need to do that -- there is only the DAG hash and specs are either
concrete and have a `dag_hash`, or not concrete and have no `dag_hash`. There's
no middle ground.

Without some enforcement of spec ordering, python 2 produced
different results in the affected test than did python 3. This
change makes the arbitrary but reproducible decision to sort
the specs by their lockfile key alphabetically.

The full hash appears twice in the spec dict now, replacing just
the value replaces it under "hash" and "full_hash". Only replace
the one that appears after "full_hash".
I'm actually not sure what purpose this test served, so maybe it
could be removed, as it may be testing some distinction between
full and dag hash which no longer exists.

For a long time, Spack has used a coarser hash to identify packages
than it likely should. Packages are identified by `dag_hash()`, which
includes only link and run dependencies. Build dependencies are
stripped before hashing, and we have notincluded hashes of build
artifacts or the `package.py` files used to build. This means the
DAG hash actually doesn't represent all the things Spack can build,
and it reduces reproducibility.
We did this because, in the early days, users were (rightly) annoyed
when a new version of CMake, autotools, or some other build dependency
would necessitate a rebuild of their entire stack. Coarsening the hash
avoided this issue and enabled a modicum of stability when only reusing
packages by hash match.
Now that we have `--reuse`, we don't need to be so careful. Users can
avoid unnecessary rebuilds much more easily, and we can add more
provenance to the spec without worrying that frequent hash changes
will cause too many rebuilds.
This commit starts the refactor with the following major change:
- [x] Make `Spec.dag_hash()` include build, run, and link
dependencides and the package hash (it is now equivalent to
`full_hash()`).
It also adds a couple of bugfixes for problems discovered during
the switch:
- [x] Don't add a `package_hash()` in `to_node_dict()` unless
the spec is concrete (fixes breaks on abstract specs)
- [x] Don't add source ids to the package hash for packages without
a known fetch strategy (may mock packages are like this)
- [x] Change how `Spec.patches` is memoized. Using
`llnl.util.lang.memoized` on `Spec` objects causes specs to
be stored in a `dict`, which means they need a hash. But,
`dag_hash()` now includes patch `sha256`'s via the package
hash, which can lead to infinite recursion

`spack pkg list` tests were broken by #29593 for cases when your `builtin.mock` repo
still has stale backup files (or, really, stale directories) sitting around. This
happens if you switch branches a lot. In this case, things like this were causing
erroneous packages in the mock listing:
```
var/spack/repos/builtin.mock/packages/
foo/
package.py~
```
- [x] make `list_packages` consider only directories with one-deep `package.py` files.

Reworking lua to allow easier substitution of the base lua implementation.
Also adding in a maintained version of luajit and re-factoring the entire stack
to use a custom build-system to centralize functionality like environment
variable management and luarocks installation.
The `lua-lang` virtual is now versioned so that a package that requires
Lua 5.1 semantics can get any lua, but one that requires 5.2 will only
get upstream lua.
The luaposix package requires lua-bit32, but only when built with a
lua conforming to version 5.1. This adds the package, and the
dependencies, but exposed a problem with luarocks dependency
detection. Since we're installing each package in its own "tree" and
there's no environment variable to list extra trees, spack now
generates a luarocks config file that lists all the trees of all the
dependencies, and references it by setting `LUAROCKS_CONFIG`
in the build environment of every LuaPackage. This allows luarocks
to find the spack installed dependencies correctly rather than
trying (and failing) to download them.

(#30468)

When running on Windows, Spack may generate files in the stage/install
prefixes that do not have write permissions, which prevents the
removal of those directories (e.g. when cleaning stages or uninstalling).
There should be a refactoring to avoid this in the first place, but that
is assumed to be longer term, so the temporary fix is to make such files
writable if they are not. This PR:
* Automatically handles these permissions errors when uninstalling
packages from the Spack root (makes then writable)
* Updates similar already-existing logic when removing Spack-managed
stage directories (the error-handling was assuming all errors were
permissions errors and was therefore handling other errors
inappropriately)
Note: these permissions issues only appear on Windows so this logic is
only applied there (permissions are not modified for this purpose on
Linux etc.).
This also adds special handling for a case where calling `isdir`
on an `os.DirEntry` object would fail for improperly-created symlinks
(e.g. on Windows, using `os.symlink` without `target_is_directory=True`).
Note this specific issue only came up when enabling link_tree tests
(specifically `source_merge_visitor_cant_be_cyclical`).

* Force GCC to always provide a C++14 flag
Updated gnu logic so that the c++14 flag for g++ is always propagated.
This fixes issues with build systems that error out if passed an empty
string for a flag.
Engaging in the best kind of software engineering by updating the unit
test to pass with the value it is now passed. This should better match
the expected flag for g++ compiling with the C++14 standard
