* rts: Use long-path-aware statBen Gamari2021-03-232-2/+6
| | | | | | | | Previously `pathstat` relied on msvcrt's `stat` implementation, which was not long-path-aware. It should rather be defined in terms of the `stat` implementation provided by `utils/fs`. Fixes #19541.

* Drop accidental write-attributes requestTamar Christina2018-10-031-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: The new filesystem code accidentally asks for write attributes permissions when doing read-only access. I believe this is what's causing the GHC 8.6.1 tarballs to fail when installed to a privileged location. I haven't been able to reproduce the issue yet, but this permission bit is wrong anyway. Test Plan: I'm still trying to workout how to test that this works, changing the permissions on the folder doesn't seem to reproduce the error on a tarball I made from before the change.

* Remove MAX_PATH restrictions from RTS, I/O manager and various utilitiesTamar Christina2018-03-313-0/+333
Summary: This shims out fopen and sopen so that they use modern APIs under the hood along with namespaced paths. This lifts the MAX_PATH restrictions from Haskell programs and makes the new limit ~32k. There are only some slight caveats that have been documented. Some utilities have not been upgraded such as lndir, since all these things are different cabal packages I have been forced to copy the source in different places which is less than ideal. But it's the only way to keep sdist working.
