ElectricFence 2.2.2_2 devel =16

Debugging malloc() that uses the VM hardware to detect buffer overruns

There is no maintainer for this port.
Any concerns regarding this port should be directed to the FreeBSD Ports mailing list via ports@FreeBSD.org
Port Added: unknown

Electric Fence is a different kind of malloc() debugger. It uses the virtual
memory hardware of your system to detect when software overruns the boundaries
of a malloc() buffer. It will also detect any accesses of memory that has
been released by free(). Because it uses the VM hardware for detection,
Electric Fence stops your program on the first instruction that causes
a bounds violation. It's then trivial to use a debugger to display the
offending statement.

It will probably port to any ANSI/POSIX system that provides mmap(), and
mprotect(), as long as mprotect() has the capability to turn off all access
to a memory page, and mmap() can use /dev/zero or the MAP_ANONYMOUS flag
to create virtual memory pages.

Complete information on the use of Electric Fence is in the manual page
efence(3).

Add two more patches found in the Linux wild. Would've been
better to be downloading them, but, strangely enough, they
don't seem available in the raw source -- only in the pretty-fied
HTML :-(

Of the two remaining once, the ElectricFence-2.2.2-madvise.patch
is currently causing me unexplained crashes, and the
ElectricFence-2.2.2-pthread.patch does not seem to matter for us,
because we don't USE_SEMAPHORE:

Add a patch found on RedHat mailing list. It is quite important,
where size_t is wider than int...

Bump PORTREVISION.

Preserve whitespace in the argument list.  This can be tested by running
"ef.sh /bin/echo a\ \ b"; the correct output is "a  b\n", but before this
commit it would print "a b\n" instead.

Disable self-tests which fail on pointyhat due to differences in
expected signal delivery between 7.x host and 6.x jail.  See patch
comment for more info.

Fix build on i386 -current.

- Add some SHA256 checksums

Try to unbreak on amd64-CURRENT.
Not sure, why suddently a differnt signal is triggered by the eftest
program.

- Prune MASTER_SITES: this particular flavour is no longer available from
perens.com
- Nuke 3-line plist while here

Noticed by: fenner's magical distfile survey

- Unbreak on non-std hardware: Use -DPAGE_PROTECTION_VIOLATED_SIGNAL=SIGBUS
   on all archs except alpha.
- Pass CC through while here.

De-pkg-comment.

Disable printing version upon initialization.
This will allow using ElectricFence in multithreaded programs
(programs linked with libc_r).

Fix bad reference.

If a user has set the EF_ALIGNMENT, EF_PROTECT_BELOW or EF_PROTECT_FREE  
variables, this can cause the ElectricFence self test to fail.    

Fix incompatiblities in the script.    

Install the shared lib version and ef wrapper script.    

Add $FreeBSD$'s which help me in problem reports.    

Convert category devel to new layout.
