2012-08-02	dummypseudo-1.3.1 PSEUDO_1_3_1	Peter Seebach

2012-03-28	cleanup and fixes	Peter Seebach
	Spotted a couple of things during the last batch of fixes; fixing these up so things are more consistent or clearer.
2012-03-27	add popen() call	Peter Seebach
	We weren't trapping popen(), so if environment variables were in an inconsistent state when popen() was called, Bad Things Happened. Add a popen() wrapper. Like a couple of other special cases, is applied even when pseudo is theoretically disabled, and that includes the antimagic case. (But we never use popen() so that's fine.)
2012-02-06	Fix *at() function interface holes	Peter Seebach
	1. Fix at() where dirfd is obtained through dirfd(DIR ). The dirfd(DIR ) interface allows you to get the fd for a DIR , meaning you can use it with openat(), meaning you can need its path. This causes a segfault. Also fixed the base_path code not to segfault in that case, but first fix the underlying problem. 2. Implement renameat() After three long years, someone tried to use this. This was impossibly hard back when pseudo was written, because there was only one dirfd provided for. Thing is, now, the canonicalization happens in wrapfuncs, so a small tweak to makewrappers to recognize that oldpath should use olddirfd if it exists is enough to get us fully canonicalized paths when needed.
2011-06-06	Improve system()	Peter Seebach

2011-06-02	Add system() wrapper to force setup of the pseudo environment. Note	Peter Seebach
	that we add an extra fork() so we can do the setup in a child process, but still just pass the command string to the standard system() call.
2011-05-31	Change logic on file creation/chmod so that we only secretly mask in	Peter Seebach
	the 0100 bit for directories. The reason is that otherwise we create plain files which are 0700 on disk, which means they're non-zero &0111, which breaks euidaccess(X_OK).
2011-03-25	Merge in ports work	Peter Seebach
	This is a spiffied-up rebase of a bunch of intermediate changes, presented as a whole because it is, surprisingly, less confusing that way. The basic idea is to separate the guts code into categories ranging from generic stuff that can be the same everywhere and specific variants. The big scary one is the Darwin support, which actually seems to run okay on 64-bit OS X 10.6. (No other variants were tested.) The other example given is support for the old clone() syscall on RHEL 4, which affects some wrlinux use cases. There's a few minor cleanup bits here, such as a function with inconsistent calling conventions, but nothing really exciting.
