2020-06-03Auto merge of #70107 - lcnr:issue68977, r=eddybbors-174/+386
WF-check all ty::Const's, not just array lengths. fixes #68977 This PR removes the special case for array length in `wf::compute` and checks the well formedness of all consts. Changes `PredicateKind::WellFormed` to take a `GenericArg` and updates `wf::obligations`.

2020-06-03Rollup merge of #72902 - cuviper:fuse-covariant, r=nikomatsakisDylan DPC-2/+3
Add a test to ensure Fuse stays covariant When #70502 attempted to specialize the data types in `Fuse`, one of the problems we found was that it broke variance. This was also realized when `Fuse` was first added, https://github.com/rust-lang/rust/pull/35656#discussion-diff-74995079, but now this PR adds a test so we don't forget again.

Remote testing fixes Improvements for remote testing - Create a `RUST_TEST_TMPDIR` directory on the remote testing host - Verbose mode for remote-test-server - Skip tests which don't support remote testing using `// ignore-remote` To test: - Build `remote-test-server` for the target machine and copy it over - On the target: ``` sh remote-test-server remote ``` - On the build machine ``` sh export TEST_DEVICE_ADDR="1.2.3.4:12345" ./x.py test ```

2020-06-02Rollup merge of #72888 - poliorcetics:improve-read_line-read_until-doc, ↵Dylan DPC-0/+8
r=Dylan-DPC Add a warning about infinite reading in read_(until|line) Fix for #48788. This PR adds a warning to [`BufRead::read_line`](https://doc.rust-lang.org/stable/std/io/trait.BufRead.html#method.read_line) and [`BufRead::read_until`](https://doc.rust-lang.org/stable/std/io/trait.BufRead.html#method.read_until) about the possibility of an attack using the behaviour of these functions. I did not mention a possible fix (using [`Read::take`](https://doc.rust-lang.org/stable/std/io/trait.Read.html#method.take), should I ?
2020-06-02Rollup merge of #72884 - Julian-Wollersberger:raw_str_error_cleanup, ↵Dylan DPC-240/+90
r=petrochenkov RawString error reporting cleanup I simplified how errors with raw string are represented in the lexer and reportet in the parser, by using one enum instead of two structs with impls. This makes 70 code lines obsolete. I also noticed some other things (2nd commit) and added a missing test for the `too many '#' symbols' error. My original intent was to improve performance, but the only thing I found was to inline some functions in `cursor.rs`. It's effect is barely measurable, though. There is one open question. Before, the compiler aborts when encountering the `too many '#' symbols` error. Now the lexer says in this case that there are 0 hashes, and then later the parser aborts on the error. I'm worrying that the parser may be changed to recover and continue, and then later stages will see the wrong numer of hashes and act strange. (eg. the `format!` macro expansion). Is that possibility important enough today to worry about it?

2020-06-02compiletest: Add name directive for remote runnersTom Eccles-0/+3
Allow tests to use // ignore-remote to ignore the test when using remote-test-{client,server}. In most situations this would be covered by // ignore-cross-compile but I see no reason that a non-cross compiled remote test runner shouldn't work.
2020-06-02tools/remote-test-server: make use of verbose optionTom Eccles-6/+16
There was an unused verbose command line argument. Add some prints if verbose is set.
2020-06-02tools/remote-test-{server,client}: support RUST_TEST_TMPDIRTom Eccles-8/+15
Some tests (e.g. ui-fulldeps/create-dir-all-bare.rs) assume that RUST_TEST_TMPDIR exists on the system running the test. Expand remote-test-{server,client} such that a tmp directory is created on the remote runner and this environment variable will point at it.
2020-06-02Auto merge of #72672 - seritools:remote-test-windows, r=Mark-Simulacrumbors-40/+89
Make remote-test-client and remote-test-server compatible with windows `compiletest` and `remote-test-client`: The command line for `remote-test-client` was changed slightly to allow cross-platform compatible paths. The old way of supplying the support libs was by joining their paths with the executable path with `:`. This caused Windows-style paths to be split after the directory letter. Now, the number of support libs is provided as a parameter as well, and the support lib paths are split off from the regular args in the client. `remote-test-server`: - Marked Unix-only parts as such and implemented Windows alternatives - On Windows `LD_LIBRARY_PATH` doesn't exist. Libraries are loaded from `PATH` though, so that's the way around it. - Tiny cleanup: `Command::args`/`envs` instead of manually looping over them - The temp path for Windows has to be set via environment variable, since there isn't a global temp directory that would work on every machine (as a static string)
