Bruce Evans	766631018f	Fixed execvp() of an empty pathname to fail POSIXly. Previously it ... attempted to exec the components of $PATH and it usually set errno to the wrong value. Found by: NIST PCTS	1996-11-18 19:24:47 +00:00
Bruce Evans	1ad652a54c	Fixed uninitialized variables for the '/'-in-pathname case in execvp(). ... Garbage in `eacces' caused the wrong errno to be set for non-EACCES errors. Garbage in `etxtbsy' caused a semi-random retry strategy for ETXTBSY errors. Found by: NIST-PCTS. gcc -Wall reported the problem, but -Wall is not enabled for libc.	1996-11-18 16:56:51 +00:00
Jordan K. Hubbard	51295a4d3e	General -Wall warning cleanup, part I. ... Submitted-By: Kent Vander Velden <graphix@iastate.edu>	1996-07-12 18:57:58 +00:00
Bruce Evans	a2c0622293	Fix execl[e]. Multiple execle's failed because of bogus caching of the ... pointer returned by realloc(). All callers free the pointer if the execve fails. Nuke the caching. This essentially restores buildargv() to the 1.1.5 version. Also fix a memory leak if realloc() fails. Also nuke similar but non-broken caching in execvp(). malloc() should be efficient enough.	1994-12-12 01:15:01 +00:00
