Which adds the `use-set-for-membership` check. It's generally faster in
python to use a set with the `in` keyword, because it's a hash check
instead of a linear walk, this is especially true with strings, where
it's actually O(n^2), one loop over the container, and an inner loop of
the strings (as string comparison works by checking that `a[n] == b[n]`,
in a loop).
Also, I'm tired of complaining about this in reviews, let the tools do
it for me :)
If we update e.g. glib.wrap from wrap-git with directory=glib to
wrap-file with directory=glib-2.70 we could still have the glib
directory that is not referenced by any .wrap file any more. We should
still ignore that directory otherwise it overrides the glib.wrap we
parsed.
Download wrap file from wrapdb automatically when it is not found
locally but we have it in wrapdb.json.
This makes for example `dependency('glib-2.0')` work out of the box
simply by running `meson wrap update-db`, even if the project does not
provide any wraps.
A subproject could have a sub-subproject as a git submodule, or part of
the subproject's release tarball, and still have a wrap file for it
(e.g. needed for [provide] section). In that case we need to use the
source tree for the sub-subproject inplace instead of downloading a new
copy into the main project.
This is the case with GLib 2.74, it has a subproject "gvdb" as git
submodule, and part of release tarball, it ships gvdb.wrap file as well.
This does force a number of uses of `# pylint: disable` comments, but it
also finds a couple of useless global uses and one place (in the
previous commit) that an easy refactor removes the use of global. Global
is a code smell, so forcing adding a comment to disable helps force
developers to really consider if what they're doing is a good idea.
Save off the hash of the wrap file when first configuring a subproject.
When reconfiguring a subproject, check the hash of the wrap file
against the stored hash. If they don't match then warn the user.
The comment and some settings that appear to be related to the comment
were introduced in f21685a833 and appears
to be documenting some of the fields added in that commit. This commit
moves the comment back to the field it appears to be documenting.
When we do wrap resolution, we do a case-insensitive lookup because
keys, i.e. `dep_name = variable_name`, are case insensitive. In order to
check whether we should process a subproject, we need to know if the
lowercased dependency name matches.
We do this by looking up the lowercase name, and assuming that the
stored name is also lowercase. But for dependency_names, this isn't "case
insensitive and stored in lowercase" so we need to manually force it to
be consistent.
Likewise, when looking up the wrap name (which works like
dependency_names and doesn't need a provide section at all) the disk
filename of the wrap file is case sensitive, but needs to be manually
forced for consistency.
When `self.wrap.filesdir` is a relative path, which happens when
`meson subprojects update` is run, the path to the patch must be
provided relative to the working directory in which `patch` or `git`
is run.
`self.wrap.filesdir` is absolute when `Resolve()` is invoked by the
Meson interpreter, which is why this wasn't detected by the tests.
We currently inconsistently handle connection, `has_ssl`, and printing
errors on urlopen failure between `meson subprojects` and `meson wrap`.
Make the latter work more like the former.
We have a fallback route in `meson subprojects download` and friends,
which tries to retrieve wrapdb urls via http, if Python was not built
with SSL support.
Stop doing this. Replace it with a command line option to specify that
insecure downloads are wanted, and reference it in the error message if
downloading fails due to SSL issues.
Using future annotations, type annotations become strings at runtime and
don't impact performance. This is not possible to do with T.cast though,
because it is a function argument instead of an annotation.
Quote the type argument everywhere in order to have the same effect as
future annotations. This also allows linters to better detect in some
cases that a given import is typing-only.
Do not traceback when trying to update a wrap that isn't a [wrap-file],
just report the problem.
Do not traceback on perfectly valid WrapDB wraps that don't have a
patch_url because they have upstream meson.build, instead try to parse
the version from the source tarball filename.
Use a derived type when passing `subproject` around, so that mypy knows
it's actually a SubProject, not a str. This means that passing anything
other than a handle to the interpreter state's subproject attribute
becomes a type violation, specifically when the order of the *four*
different str arguments is typoed.
This code path is only called on initial download of a subproject, but
if we raise an error and abort while downloading/applying a patch
overlay we still have the upstream sources extracted... which appears to
be a subproject, then turns out to be broken due to missing meson.build
Partially implements #9688
In some cases, init variables that accept None as a sentinel and
immediately overwrite with [], are migrated to dataclass field
factories. \o/
Note: dataclasses by default cannot provide eq methods, as they then
become unhashable. In the future we may wish to opt into declaring them
frozen, instead/additionally.
Since 0.59.0 Meson downloads multiple wraps in parallel, so the
packagecache directory could be created by one then the 2nd would hit
error when calling os.mkdir() because it already exists.
both of these do the same thing:
init -b <branchname>
-c init.defaultBranch=<branchname> init
The latter contributes to unreadably long lines of code, but has the
advantage of working on older versions of git.
Fixes#9449
Now, warnings are unconditionally raised when parsing the wrap file,
whether they are used or not. That being said, these warnings literally
just check for a couple of keys used in the .wrap ini file.
Moving these checks from the time of use to the time of loading, means
that we no longer report warnings only when originally downloading or
extracting the file or VCS repo.
It also means we no longer report warnings in one subproject, when a
wrap file is picked up from a different subproject because the first
subproject actually does a dependency lookup. This caused issues for the
WrapDB tooling, which uses patch_directory everywhere and the
superproject requires a suitable minimum version of meson for this...
but individual wraps might use a much lower version, and would then
raise a warning (in strict mode, converted to an error) when it resolved
a dependency from another WrapDB project.
Fixes#9118
There are two possible issues, both of which emit very long messages
from git:
- when shallow cloning via depth + a pinned commit we locally init
rather than cloning; use an almost-certainly not conflicting dummy
branch name
- any time a checkout of a revision is performed, it might not be a
branch name, in which case it will be a detached HEAD. By default git
is very noisy about this -- it wants you to know what happened and how
not to mess up. But wraps aren't per default intended for user editing
and development, it's just part of the internal transport which meson
uses. So, temporarily squelch this advice. Do not permanently
configure the repo like this though, because the user *might* cd in
and start developing on the subproject; in this case, any additional
git advice they trigger is their responsibility (and they probably do
want it).
Fixes#9318
"ERROR: Git program not found" is both highly true, and somewhat
inscrutable. Sure, looking at the line number you can basically figure
out that subproject('something') must somehow need git to operate, but
that may not be immediately obvious.
Make mention of the fact that it is needed to "download foo.wrap".
Fixes#7764
We have a lot of these. Some of them are harmless, if unidiomatic, such
as `if (condition)`, others are potentially dangerous `assert(...)`, as
`assert(condtion)` works as expected, but `assert(condition, message)`
will result in an assertion that never triggers, as what you're actually
asserting is `bool(tuple[2])`, which will always be true.
The dependency lookup is a lot of complex code. This refactor it all
into a single file/class outside of interpreter main class. This new
design allows adding more fallbacks candidates in the future (e.g. using
cc.find_library()) but does not yet add any extra API.
