pipestatus - source file for POSIX shell that allows
to obtain an exit status of every program in a pipe.
MOTIVATION
When we program in shell we often run pipes like this
prog1 args1 | prog2 args2 | ... | progN argsN
POSIX says that exit status of pipe is the exit status of LAST program
in it, i.e. progN in our example. That is, exit status of all other
programs in pipe is silently ignored. But in many situations exit
status of all programs in pipe should be checked to make program
robust. Some shells like BASH and ZSH have special extensions for
doing this but POSIX shell unfortunately doesn't provide an EASY way
for doing this.
In order to solve the problem, described above pipestatus was written.
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
(Only the first 15 lines of the commit message are shown above )
Clean up my ports (and a couple of ports@ owned ones):
- Fix COMMENT
- Add MAKE_JOBS_SAFE where appropriate
- Change ordering of LICENSE lines
- Fix new header format
- Etc.
