fbbd9655 - Renumber copyright clause 4

Tue, 28 Feb 2017 23:42:47 +0000

Renumber copyright clause 4Renumber cluase 4 to 3, per what everybody else did when BSD grantedthem permission to remove clause 3. My insistance on keeping the samenumbering for legal reasons is too pedantic, so give up on that point.Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96 List of files: /freebsd-12.1/bin/sh/exec.h

84fbdd8c - sh: Expand assignment-like words specially for export/readonly/local.

Sun, 15 Jul 2012 10:19:43 +0000

sh: Expand assignment-like words specially for export/readonly/local.Examples: export x=~now expands the tilde local y=$1is now safe, even if $1 contains IFS characters or metacharacters.For a word to "look like an assignment", it must start with a name followedby an equals sign, none of which may be quoted.The special treatment applies when the first word (potentially after"command") is "export", "readonly" or "local". There may be quotingcharacters but no expansions. If "local" is overridden with a function thereis no special treatment ("export" and "readonly" cannot be overridden with afunction).If things like local arr=(1 2 3)are ever allowed in the future, they cannot call a "local" function. Thiswould either be a run-time error or it would call the builtin.This matches Austin Group bug #351, planned for the next issue of POSIX.1.PR: bin/166771 List of files: /freebsd-12.1/bin/sh/exec.h

3835f47c - sh: Remove special code for shell scripts without magic number.

Fri, 04 Feb 2011 22:47:55 +0000

sh: Remove special code for shell scripts without magic number.These are called "shell procedures" in the source.If execve() failed with [ENOEXEC], the shell would reinitialize itselfand execute the program as a script. This requires a fair amount of codewhich is not frequently used (most scripts have a #! magic number).Therefore just execute a new instance of sh (_PATH_BSHELL) to run thescript.

85170a4a - Implement some of the differences between special built-ins and other builtins

Sun, 09 Apr 2006 12:21:20 +0000

Implement some of the differences between special built-ins and other builtinsdemanded by POSIX.- A redirection error is only fatal (meaning the execution of a shell script is terminated) for special built-ins. Previously it was fatal for all shell builtins, causing problems like the one reported in PR 88845.- Variable assignments remain in effect for special built-ins.- Option or operand errors are only fatal for special built-ins.This change also makes errors from 'fc' non-fatal (I could not find any reasonsfor this behaviour).Somewhat independently from the above down-grade the error handling in theshift built-in if the operand is bigger than $# from an error() call (which isnow fatal) to a return 1. I'm not sure if this should be considered a POSIX"operand error", however this change is needed for now as we trigger that errorwhile building libncurses. Comparing with other shells, zsh does the same asour sh before this change (write a diagnostic, return 1), bash behaves as oursh after this commit (no diagnostic, return 1) and ksh93 and NetBSD's sh treatit as a fatal error.
