| | | | | | | | | | it to kick off a new command before the previous has finished, resulting in corrupted (interleaved) output. It is also fooled by non-exiting children it did not start, failing to exit until all extraneous children have exited. This patch makes xargs keep track of children it starts, ignoring pre-existing ones.

| | | | | | | | | | | | | but don't expect a proper ASCII string to exist right here right now, don't use strcmp(3) which checks for a NUL. As we're still building the argument up, the next character might be garbage. It would probably be just as safe to temporarily write a NUL there, but if we've reached the end of argument memory that might not be the best idea, I think. It's unclear. Doing it this way seems to meet the most with the original intent. PR: 85696 Prodded by: stefanf

* Modify behaviour of `xargs -I` in order to:cperciva2004-10-181-2/+2
| | | | | | | | | | | | | | | | | 1. Conform to IEEE Std 1003.1-2004, which state that "Constructed arguments cannot grow larger than 255 bytes", and 2. Avoid a buffer overflow. Unfortunately the standard doesn't indicate how xargs is supposed to handle arguments which (with the appropriate substitutions) would grow larger than 255 bytes; this solution handles those by making as many substitutions as possible without overflowing the buffer. OpenBSD's xargs resolves this in a different direction, by making all the substitutions and then silently truncating the resulting string. Since this change may break existing scripts which rely upon the buffer overflow (255 bytes isn't really all that long...) it will not be MFCed.

There was one problem in those fixes that broke -o, which is corrected here and should be committed to the OpenBSD repo by Todd soon. MFC in: 3 days

* Migrate to a new way of dealing with building from old revisions ofimp2003-04-051-14/+1
| | | | | | | | | | | | | | | | | FreeBSD. This method attempts to centralize all the necessary hacks or work arounds in one of two places in the tree (src/Makefile.inc1 and src/tools/build). We build a small compatibility library (libbuild.a) as well as selectively installing necessary include files. We then include this directory when building host binaries. This removes all the past release compatibilty hacks from various places in the tree. We still build on tip of stable and current. I will work with those that want to support more, although I anticipate it will just work. Many thanks to ru@, obrien@ and jhb@ for providing valuable input at various stage of implementation, as well as for working together to positively effect a change for the better.

Without -o, the application would inherit the pipe as its stdin, and you thus lose any control over it. This flag has been carefully chosen to not conflit with other options of other xargs utilities like GNU xargs. Reviewed by: jmallett
