Lock transactions were actually writing *after* the lock was
released. The code was looking at the result of `release_write()` before
writing, then writing based on whether the lock was released. This is
pretty obviously wrong.
- [x] Refactor `Lock` so that a release function can be passed to the
`Lock` and called *only* when a lock is really released.
- [x] Refactor `LockTransaction` classes to use the release function
instead of checking the return value of `release_read()` / `release_write()`

`ViewDescriptor.regenerate()` checks repeatedly whether packages are
installed and also does a lot of DB queries. Put a read transaction
around the whole thing to avoid repeatedly locking and unlocking the DB.
|
|
`Environment.added_specs()` has a loop around calls to
`Package.installed()`, which can result in repeated DB queries. Optimize
this with a read transaction in `Environment`.
|
|
`spack spec -I` queries the database for installation status and should
use a read transaction around calls to `Spec.tree()`.
|
|
Checks for deprecated specs were repeatedly taking out read locks on the
database, which can be very slow.
- [x] put a read transaction around the deprecation check
|
|
`get_platform()` is pretty expensive and can be called many times in a
spack invocation.
- [x] memoize `get_platform()`

BundlePackages use a noop fetch strategy. The mirror logic was assuming
that the fetcher had a resource to cach after performing a fetch. This adds
a special check to skip caching if the stage is associated with a
BundleFetchStrategy. Note that this should allow caching resources
associated with BundlePackages.
|
|
When updating a mirror, Spack was re-retrieving all patches (since the
fetch logic for patches is separate). This updates the patch logic to
allow the mirror logic to avoid this.
|
|
Since cache_mirror does the fetch itself, it also needs to do the
checksum itself if it wants to verify that the source stored in the
mirror is valid. Note that this isn't strictly required because fetching
(including from mirrors) always separately verifies the checksum.

The targets for the cosmetic paths in mirrrors were being calculated
incorrectly as of fb3a3ba: the symlinks used relative paths as targets,
and the relative path was computed relative to the wrong directory.
|
|
When creating a cosmetic symlink for a resource in a mirror, remove
it if it already exists. The symlink is removed in case the logic to
create the symlink has changed.

(#13789)
* Some packages (e.g. mpfr at the time of this patch) can have patches
with the same name but different contents (which apply to different
versions of the package). This appends part of the patch hash to the
cache file name to avoid conflicts.
* Some exceptions which occur during fetching are not a subclass of
SpackError and therefore do not have a 'message' attribute. This
updates the logic for mirroring a single spec (add_single_spec)
to produce an appropriate error message in that case (where before
it failed with an AttributeError)
* In various circumstances, a mirror can contain the universal storage
path but not a cosmetic symlink; in this case it would not generate
a symlink. Now "spack mirror create" will create a symlink for any
package that doesn't have one.

`spack module loads` and `spack module find` previously failed if any upstream modules were missing. This prevented it from being used with upstreams (or, really, any spack instance) that blacklisted modules.
This PR makes module finding is now more lenient (especially for blacklisted modules).
- `spack module find` now does not report an error if the spec is blacklisted
- instead, it prints a single warning if any modules will be omitted from the loads file
- It comments the missing modules out of the loads file so the user can see what's missing
- Debug messages are also printed so users can check this with `spack -d...`
- also added tests for new functionality

* Add a transaction around repeated calls to `spec.prefix` in the activation process
* cache the computation of home in the python package to speed up setting deps
* ensure that module-scope variables are only set *once* per module

`mirror_archive_path` was failing to account for the case where the fetched version isn't known to Spack.
- [x] don't require the fetched version to be in `Package.versions`
- [x] add regression test for mirror paths when package does not have a version

* remove reference to `spack.store` in method definition
Referencing `spack.store` in method definition will cache the `spack.config.config` singleton variable too early, before we have a chance to add command line and environment scopes.

Add a configuration option to suppress gpg warnings during binary
package verification. This only suppresses warnings: a gpg failure
will still fail the install. This allows users who have already
explicitly trusted the gpg key they are using to avoid seeing
repeated warnings that it is self-signed.

Binaries with relative RPATHS currently do not relocate strings
hard-coded in binaries
This PR extends the best-effort relocation of strings hard-coded
in binaries to those whose RPATHs have been relativized.
|

If you do this in a spack environment:
spack add hdf5+hl
hdf5+hl will be the root added to the `spack.yaml` file, and you should
really expect `hdf5+hl` to display as a root in the environment.
- [x] Add decoration to roots so that you can see the details about what
is required to build.
- [x] Add a test.

This fixes a regression introduced in #10792. `spack uninstall` in an
environment would not match concrete query specs properly after the index
hash of enviroments changed.
- [x] Search by DAG hash for specs to remove instead of by build hash

- [x] insert at beginning of list so fetch grabs local mirrors before remote resources
- [x] update the S3FetchStrategy so that it throws a SpackError if the fetch fails.
Before, it was throwing URLError, which was not being caught in stage.py.
- [x] move error handling out of S3FetchStrategy and into web_util.read_from_url()
- [x] pass string instead of URLError to SpackWebError

This changes Spack environments so that the YAML file associated with the environment is *only* written when necessary (i.e., if it is changed *by spack*). The lockfile is still written out as before.
There is a larger question here of which part of Spack should be responsible for setting defaults in config files, and how we can get rid of empty lists and data structures currently cluttering files like `compilers.yaml`. But that probably requires a rework of the default-setting validator in `spack.config`, as well as the code that uses `spack.config`. This will at least help for `spack.yaml`.

Currently, query arguments in the Spack core are documented on the
Database._query method, where the functionality is defined.
For users of the spack python command, this makes the python builtin
method help less than ideally useful, as help(spack.store.db.query)
and help(spack.store.db.query_local) do not show relevant information.
This PR updates the doc attributes for the Database.query and
Database.query_local arguments to mirror everything after the first
line of the Database._query docstring.

Support mirroring all packages with `spack mirror create --all`.
In this mode there is no concretization:
* Spack pulls every version of every package into the created mirror.
* It also makes multiple attempts for each package/version combination
(if there is a temporary connection failure).
* Continues if all attempts fail. i.e., this makes its best effort to
fetch evrerything, even if all attempts to fetch one package fail.
This also changes mirroring logic to prefer storing sources by their hash
or by a unique name derived from the source. For example:
* Archives with checksums are named by the sha256 sum, i.e.,
`archive/f6/f6cf3bd233f9ea6147b21c7c02cac24e5363570ce4fd6be11dab9f499ed6a7d8.tar.gz`
vs the previous `<package-name>-package-version>.tar.gz`
* VCS repositories are stored by a path derived from their URL,
e.g. `git/google/leveldb.git/master.tar.gz`.
The new mirror layout allows different packages to refer to the same
resource or source without duplicating that download in the
mirror/cache. This change is not essential to mirroring everything but is
expected to save space when mirroring packages that all use the same
resource.
The new structure of the mirror is:
```
<base directory>/
_source-cache/ <-- the _source-cache directory is new
archive/ <-- archives/resources/patches stored by hash
00/ <-- 2-letter sha256 prefix
002748bdd0319d5ab82606cf92dc210fc1c05d0607a2e1d5538f60512b029056.tar.gz

0173a74a515211997a3117a47e7b9ea43594a04b865b69da5a71c0886fa829ea.tar.gz

...
svn/ <-- each fetch strategy has its own subdirectory
...
openmpi/ <-- the remaining package directories have the old format
openmpi-1.10.1.tar.gz <-- human-readable name is symlink to _source-cache
```
In addition to the archive names as described above, `mirror create` now
also creates symlinks with the old format to help users understand which
package each mirrored archive is associated with, and to allow mirrors to
work with old spack versions. The symlinks are relative so the mirror
directory can still itself be archived.
Other improvements:
* `spack mirror create` will not re-download resources that have already
been placed in it.
* When creating a mirror, the resources downloaded to the mirror will not
be cached (things are not stored twice).

Restore upstream lock safety; avoid calling methods directly on upstream DB in test.

(#13435)

reindexing takes a significant amount of time, and there's no reason to
do it from DB version 0.9.3 to version 5. The only difference is that v5
can contain "deprecated_for" fields.
- [x] Add a `_skip_reindex` list at the start of `database.py`
- [x] Skip the reindex for upgrades in this list. The new version will
just be written to the file the first time we actually have to write
the DB out (e.g., after an install), and reads will still work fine.
|
|
Previously, spack would error out if we tried to fetch something with no
code, but that would prevent fetching dependencies. In particular, this
would fail:
spack fetch --dependencies xsdk
- [x] Instead of raising an error, just print a message that there is nothing
to be fetched for packages like xsdk that do not have code.
- [x] Make BundleFetchStrategy a bit more quiet about doing nothing.
|
|
We've had `spack spec --yaml` for a while, and we've had methods for JSON
for a while as well. We just haven't has a `--json` argument for `spack spec`.
- [x] Add a `--json` argument to `spack spec`, just like `--yaml`
