jilles 2010-10-24 22:03:21 UTC FreeBSD src repository Modified files: bin/sh parser.c Added files: tools/regression/bin/sh/execution func3.0 Log: SVN rev 214304 on 2010-10-24 22:03:21Z by jilles sh: Do not allow overriding a special builtin with a function. This is a syntax error. POSIX does not say explicitly whether defining a function with the same name as a special builtin is allowed, but it does say that it is impossible to call such a function. A special builtin can still be overridden with an alias. This commit is part of a set of changes that will ensure that when something looks like a special builtin to the parser, it is one. (Not the other way around, as it remains possible to call a special builtin named by a variable or other substitution.) Exp-run done by: pav (with some other sh(1) changes) Revision Changes Path 1.91 +5 -0 src/bin/sh/parser.c 1.1 +7 -0 src/tools/regression/bin/sh/execution/func3.0 (new)
