This commit was manufactured to restore the state of the 3.2-RELEASE image. Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs. Fixed searching of $PATH in execvp(). Do what sh(1) should do according 1997-10-14T07:23:16Z Bruce Evans bde@FreeBSD.org 1997-10-14T07:23:16Z urn:sha1:1df595f25dae340c439be4d028cbb72a0894e1a6 to POSIX.2. In particular: - don't retry for ETXTBSY. This matches what sh(1) does. The retry code was broken anyway. It only slept for several seconds for the first few retries. Then it retried without sleeping. - don't abort the search for errors related to the path prefix, in particular for ENAMETOOLONG, ENOTDIR, ELOOP. This fixes PR1487. sh(1) gets this wrong in the opposite direction by never aborting the search. - don't confuse EACCES for errors related to the path prefix with EACCES for errors related to the file. sh(1) gets this wrong. - don't return a stale errno when the search terminates normally without finding anything. The errno for the last unsuccessful execve() was usually returned. This gave too much precedence to pathologies in the last component of $PATH. This bug is irrelevant for sh(1). The implementation still uses the optimization/race-inhibitor of trying to execve() things first. POSIX.2 seems to require looking at file permissions using stat(). We now use stat() after execve() if execve() fails with an ambiguous error. Trying execve() first may actually be a pessimization, since failing execve()s are fundamentally a little slower than stat(), and are significantly slower when a file is found but has unsuitable permissions or points to an unsuitable interpreter. PR: 1487 Fixed synopsis. The envp arg for execle() can't be given in the prototype. 1997-09-03T03:25:35Z Bruce Evans bde@FreeBSD.org 1997-09-03T03:25:35Z urn:sha1:853aa1faf37cd30b2166fc6a35aaf87aa0475aa7 Fortunately, the man page doesn't refer to "envp" so just deleting it is OK. Fixed various problems: typos, grammer, missing include files 1996-05-23T01:05:25Z Mike Pritchard mpp@FreeBSD.org 1996-05-23T01:05:25Z urn:sha1:712dc76e87bd7bbeb3f781e690886b69a1f9c5ca wrong function type declarations, and wrong argument type declarations.
