Fixes #10682
|
|
This is part of the effort to simplify `std::num`, as tracked in issue #10387.
|
|
Previously an `unsafe` block created by the compiler (like those in the
formatting macros) would be "ignored" if surrounded by `unsafe`, that
is, the internal unsafety would be being legitimised by the external
block:
unsafe { println!("...") } =(expansion)=> unsafe { ... unsafe { ... } }
And the code in the inner block would be using the outer block, making
it considered used (and the inner one considered unused).
This patch forces the compiler to create a new unsafe context for
compiler generated blocks, so that their internal unsafety doesn't
escape to external blocks.
Fixes #12418.

This commit rewrites crate loading internally in attempt to look at less
metadata and provide nicer errors. The loading is now split up into a few
stages:
1. Collect a mapping of (hash => ~[Path]) for a set of candidate libraries for a
given search. The hash is the hash in the filename and the Path is the
location of the library in question. All candidates are filtered based on
their prefix/suffix (dylib/rlib appropriate) and then the hash/version are
split up and are compared (if necessary).
This means that if you're looking for an exact hash of library you don't have
to open up the metadata of all libraries named the same, but also in your
path.
2. Once this mapping is constructed, each (hash, ~[Path]) pair is filtered down
to just a Path. This is necessary because the same rlib could show up twice
in the path in multiple locations. Right now the filenames are based on just
the crate id, so this could be indicative of multiple version of a crate
during one crate_id lifetime in the path. If multiple duplicate crates are
found, an error is generated.
3. Now that we have a mapping of (hash => Path), we error on multiple versions
saying that multiple versions were found. Only if there's one (hash => Path)
pair do we actually return that Path and its metadata.
With this restructuring, it restructures code so errors which were assertions
previously are now first-class errors. Additionally, this should read much less
metadata with lots of crates of the same name or same version in a path.
Closes #11908

Fix generic Drop impls with trait bounds.
Fixes #4252.

Fixes #12333.
I also re-enabled the *function-arg-initialization* test case, so if it passes again, fixes #12021.

The new methodology can be found in the re-worded comment, but the gist of it is
that -C prefer-dynamic doesn't turn off static linkage. The error messages
should also be a little more sane now.

Preparatory work for removing unique vectors from the language, which is
itself preparatory work for dynamically sized types.

When creating a staticlib, it unzips all static archives it finds and then
inserts the files manually into the output file. This process is done through
`ar`, and `ar` doesn't like if you specify you want to add files and you don't
give it any files.
This case arose whenever you linked to an archive that didn't have any contents
or all of the contents were filtered out. This just involved ignoring the case
where the number of inputs we have is 0, because we don't have any files to add
anyway.

Currently, the format_args! macro and its downstream macros in turn
expand to series of let statements, one for each of its arguments, and
then the invocation of the macro function. If one or more of the
arguments are RefCell's, the enclosing statement for the temporary of
the let is the let itself, which leads to scope problem. This patch
changes let's to a match expression.
Closes #12239.

Closes #11692. Instead of returning the original expression, a dummy expression
(with identical span) is returned. This prevents infinite loops of failed
expansions as well as odd double error messages in certain situations.
This is a slightly better fix than #12197, because it does not produce a double error and also fixes a few other cases where an infinite loop could happen.
This does not fix the other issue in #11692 (non-builtin macros not being recognised when expanded inside macros), which I think should be moved into a separate issue.

With Rc no longer trying to statically prevent cycles (and thus no
longer using the Freeze bound), it seems appropriate to remove that
restriction from MutexArc as well.

Delete all the documentation from std::task that references linked
failure.
Tweak TaskBuilder to be more builder-like. `.name()` is now `.named()` and
`.add_wrapper()` is now `.with_wrapper()`. Remove `.watched()` and
`.unwatched()` as they didn't actually do anything.
Closes #6399.

This just copies the libuv implementation for libnative which seems reasonable

These are adequately covered by the Tuple2 trait.

Renames the `n*` and `n*_ref` tuple getters to `val*` and `ref*` respectively, and adds `mut*` getters.

This notably contains the `extern mod` => `extern crate` change.

Mostly just style fixes, but also remove a heap allocation and switch to using a buffered writer rather than doing 60,000 `println!`s.

This was previously implemented, and it just needed a snapshot to go through
