Detach from the child process before completing the test.

2018-07-27T20:34:15+00:00

Otherwise the child will receive SIGTRAP if the parent exits first.

Add an envp argument to proc_create().

2017-12-03T16:50:16+00:00

This is needed to support dtrace's -x setenv option.

Eliminate the last user of basename_r() in the base system.

2017-12-01T10:25:52+00:00

In this case it's fairly easy to make use of basename().

Refine symtab sorting in libproc.

Add some rules to more closely match what illumos does when an address
resolves to multiple symbols:
- prefer non-local symbols
- prefer symbols with fewer leading underscores and no leading '$'

Add some regression tests to verify these rules.

libproc: Match prefixes when looking up mapped object by name.

2016-12-06T04:20:32+00:00

When looking up an object by name, allow prefix matches if no direct match
is found. This allows one to, for example, match libc entry probes with:

 # dtrace -n 'pid$target:libc.so::entry' -c ./foo

instead of requiring "libc.so.7" or a glob.

Also remove proc_obj2map() as it currently just duplicates the
functionality of proc_name2map(). It's supposed to take a Solaris
link-map ID as a paramter, but support for this isn't implemented and
isn't required to support DTrace's pid provider.

Enable libproc symbol_lookup tests on arm64

2015-08-31T20:30:06+00:00

This reverts part of r286863, as the kernel support required by these
tests was added in r287105.

On arm64 disable three tests that hang or panic

2015-08-17T23:19:36+00:00

Each issue has a PR open to track. This workaround allows us to run the
tests to investigate the failures and avoid any new regressions.
