Two commits here: one which removes a bunch of tests, and re-enables a few that work.
Second updates the syntax of one of the failing tests. It still doesn't pass, but at least it compiles.
This is a revert of PR #26008 which caused the unintended breakage reported in #26096. We may want to add these implementations in the long run, but for now this revert allows us to take some more time to evaluate the impact of such a change (e.g. run it through crater).
Closes#26096
This commit stabilizes the following APIs, slating them all to be cherry-picked
into the 1.1 release.
* fs::FileType (and transitively the derived trait implementations)
* fs::Metadata::file_type
* fs::FileType::is_dir
* fs::FileType::is_file
* fs::FileType::is_symlink
* fs::DirEntry::metadata
* fs::DirEntry::file_type
* fs::DirEntry::file_name
* fs::set_permissions
* fs::symlink_metadata
* os::raw::{self, *}
* os::{android, bitrig, linux, ...}::raw::{self, *}
* os::{android, bitrig, linux, ...}::fs::MetadataExt
* os::{android, bitrig, linux, ...}::fs::MetadataExt::as_raw_stat
* os::unix::fs::PermissionsExt
* os::unix::fs::PermissionsExt::mode
* os::unix::fs::PermissionsExt::set_mode
* os::unix::fs::PermissionsExt::from_mode
* os::unix::fs::OpenOptionsExt
* os::unix::fs::OpenOptionsExt::mode
* os::unix::fs::DirEntryExt
* os::unix::fs::DirEntryExt::ino
* os::windows::fs::MetadataExt
* os::windows::fs::MetadataExt::file_attributes
* os::windows::fs::MetadataExt::creation_time
* os::windows::fs::MetadataExt::last_access_time
* os::windows::fs::MetadataExt::last_write_time
* os::windows::fs::MetadataExt::file_size
The `os::unix::fs::Metadata` structure was also removed entirely, moving all of
its associated methods into the `os::unix::fs::MetadataExt` trait instead. The
methods are all marked as `#[stable]` still.
As some minor cleanup, some deprecated and unstable fs apis were also removed:
* File::path
* Metadata::accessed
* Metadata::modified
Features that were explicitly left unstable include:
* fs::WalkDir - the semantics of this were not considered in the recent fs
expansion RFC.
* fs::DirBuilder - it's still not 100% clear if the naming is right here and if
the set of functionality exposed is appropriate.
* fs::canonicalize - the implementation on Windows here is specifically in
question as it always returns a verbatim path. Additionally the Unix
implementation is susceptible to buffer overflows on long paths unfortunately.
* fs::PathExt - as this is just a convenience trait, it is not stabilized at
this time.
* fs::set_file_times - this funciton is still waiting on a time abstraction.
Most of these are old, but some specific messages for specific tests:
* trait-contravariant-self.rs: failed due to a soundess hole:
05e3248a79
* process-detatch: 15966c3c1f
says "this test is being ignored until signals are implemented" That's
not happening for a long time, and when it is, we'll write tests for
it.
* deep-vector{,2}.rs: "too big for our poor macro infrastructure", and has
been ignored over a year.
* borrowck-nested-calls.rs's FIXME #6268 was closed in favor of
rust-lang/rfcs#811
* issue-15167.rs works properly now
* issue-9737.rs works properly now
* match-var-hygiene.rs works properly now
Addresses a chunk of #3965
Explain the --bin flag in terms of the difference
between shipping binary and library code
I'm not sure if my explanation is even quite correct, but as a newbie coming from Ruby, this is my best guess. (In Rubyland, libraries always ship with the source code because there's no other form you can ship. :) )
Suggesting this because I was confused by what is now visible from the Travis CI / buildbot split.

Couldn't find anything on https://internals.rust-lang.org/
Right now the distribution tarball for MSVC only includes the *.dll files for
the supporting libraries, but not the corresponding *.lib files which allow
actually linking to the dll. This means that the current MSVC nightlies cannot
produce dynamically linked binaries as the *.lib files are not available to link
against.
This commit modifies the `LIB_GLOB` used to copy the files around to include the
`lib` variant of the `dll`.
`driver::build_output_filenames` calls `file_stem` on a PathBuf obtained from the output file compiler flag. It's possible to pass the empty string to this compiler flag. When file_stem is called on an empty Path, it returns None, which is unwrapped and the compiler panics.
This change modifies the `unwrap` to an `unwrap_or` so that the empty string is passed through the compilation pipeline until it reaches `trans:🔙:write_output_file`, which will emit an appropriate error.
Instead of panicking, the error that is emitted now is:
```
$ rustc -o "" thing.rs
error: could not write output to : No such file or directory
```
The `:` is a little strange, but it /is/ reporting the filename (the empty string) correctly, I suppose. Both gcc and clang hand the output file to ld, which emits a similar error message when faced with the empty string as an output file:
```
$ clang -o "" thing.c
ld: can't open output file for writing: , errno=2 for architecture x86_64
```
This PR also adds a test for this, in `run-make`. This fixes issue #26092.

These errors all relate to type checking, specifically the number of function arguments, and occur in librustc_typeck::check::check_argument_types.
Resolves part of #24407.
* Slate these features to be stable in 1.2 instead of 1.1 (not being backported)
* Have the `FromRawFd` implementations follow the contract of the `FromRawFd`
trait by taking ownership of the primitive specified.
* Refactor the implementations slightly to remove the `unreachable!` blocks as
well as separating the stdio representation of `std::process` from
`std::sys::process`.
cc #25494
Converts the size calculation in the explanation from a fenced code block to an indented one. I think it looks better when not rendered, and is the same rendered.
In the discussion of returning closures, it seems like the example code got simplified, but only the later copies got fixed. The final working code has `factory` returning `|x| x + num`, but the earlier code has `|x| vec.push(x)`.
The first form seemed to have more distracting characteristics, and the code wasn't right anyway, so I changed them to all use the second form, and updated the error messages.

… congruent due to rounding errors
@semarie this affected both openbsd and bitrig. it seems the correct solution is to switch to fixed point arithmetic in the timeout code, the same as freebsd.
Various methods in both libcore/char.rs and librustc_unicode/char.rs were previously marked with #[inline], now every method is marked in char's impl blocks.
Partially fixes#26124.
EDIT: I'm not familiar with pull reqests (yet), apparently Github added my second commit to thit PR...
Fixes#26124
