* MFC r292517: sh/mknodes: Close files and check for errors when writing.Jilles Tjoelker2015-12-271-5/+15
| | | | | | | | | This is a build tool only and does not affect run time. PR: 204951 Notes: svn path=/stable/10/; revision=292786
* sh: Fix crash with empty functions (f() { }) introduced in r196483Jilles Tjoelker2009-08-281-4/+2
| | | | | | | | | | | | | | | Empty pairs of braces are represented by a NULL node pointer, just like empty lines at the top level. Support for empty pairs of braces may be removed later. They make the code more complex, have inconsistent behaviour (may or may not change $?), are not specified by POSIX and are not allowed by some other shells like bash, dash and ksh93.

* sh: Fix crash when undefining or redefining a currently executing function.Jilles Tjoelker2009-08-231-2/+7
| | | | | | | | | | | Add a reference count to function definitions. Memory may leak if multiple SIGINTs arrive in interactive mode, this will be fixed later by changing SIGINT handling. PR: bin/137640 Notes: svn path=/head/; revision=196483
* Mark functions as __dead2 in order to help the LLVM static checkerColin Percival2008-08-041-1/+1

| | | | | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise. Notes: svn path=/head/; revision=21673

* Misc cleanups and fixes from Bruce:Peter Wemm1996-09-031-2/+2
| | | | | | | | | | | | | - don't put \n on error() calls, error adds it already. - don't prepend "ulimit" on error() calls in miscbltin.c. - getopt typo on ulimit -p -> -u conversion - get/setrlimit() calls were not being error checked ulimit formatting cleanup from me, use same wording as bash on Bruce's suggestion. Add ulimit arg to output on Joerg's suggestion. Notes: svn path=/head/; revision=18016

| | | | | | | | | | | | | | | | | merge of parallel duplicate work by Steve Price and myself. :-] There are some changes to the build that are my fault... mkinit.c was trying (poorly) to duplicate some of the work that make(1) is designed to do. The Makefile hackery is my fault too, the depend list was incomplete because of some explicit OBJS+= entries, so mkdep wasn't picking up their source file #includes. This closes a pile of /bin/sh PR's, but not all of them.. Submitted by: Steve Price <steve@bonsai.hiwaay.net>, peter Notes: svn path=/head/; revision=17987
