Bend Files

• bend --publish sends only files inside the entry's directory: a ../ climb, a symlink out of it or a LICENSE that links out is refused before mining, with no hub request (#1836, PR [#1838] by oxura).
• File.open(path, "x") creates a new file and fails with EEXIST if the path exists, in one step (#1821, PR [#1824]).
• Non-UTF-8 arguments: IO.args_bytes gives each argument's bytes, and File.open_bytes opens a path given as bytes (#1798, PR [#1799] by viridale).
• Process.run runs through one worker on Bun and Node, so it no longer ends the run on Node, and a child that leaves stdin unread no longer hangs it (#1468, PR [#1831] by oxura).
• Metal: the lane spill of 2.0.38 is gone (PR [#1809]): it made bend -o of a ! program build 17% slower. A full lane fails with ERR_DEEP again, as in 2.0.37.
• Fixes:
• The GPU build sees a closure in a later instance of the same datatype (#1513, PR #1542).
• C: a read-only walk borrows its list when a sum type puts a word where another constructor has a box (#1805, PR #1806 by viridale); a memory fault ends the program by its signal (SIGSEGV, SIGBUS), not exit 1, after flushing output (PR #1828 by oxura).
• IO.get_env refuses a name with a =, which read part of another variable on C and Node (#1794, PR #1795 by orezraey).
• CLI: bend -o never overwrites an input through a hard link or with the GPU archive <out>.gpu (PRs [#1797] by sebastian-griego and [#1826] by toprameen); a $CC that is not a usable clang 14+ ends the build with its reason, instead of a silent plain-clang build (#1802, PR [#1804] by Yi-111-a).
• Tools: the formatter keeps body columns after (, ;, tuple commas and in nested lambdas, and keeps a generic's > apart from a following = (PRs [#1803] by toprameen, [#1811], [#1816], [#1833], [#1839] by vicmcorrea).
• Docs: BendTT proves adequacy, a checked law holds at each closed instance (PR [#1627] by ScottMoore0); the guide and BendRT say a hot type counts the fields of every node, shared or not (#1559, PRs [#1812] by vicmcorrea and [#1813]), and BendRT matches the runtime on the corpus, JS requests and the CUDA cube (#1822, PR [#1823]).
