Here's a preliminary port of strace to FreeBSD.
|
|
|
|
Here are some notes about it :
|
|
|
|
- This couldn't have been done without the sources of the truss
|
|
utility by Sean Eric Fagan, which were of great help.
|
|
|
|
- The tracing mecanism used by FreeBD is a lot like the SVR4 one, so
|
|
this port shares a lot of code with the SVR4 port, including the
|
|
akward event loop when tracing multiple processes.
|
|
|
|
- This works for i386 binaries, although support for alpha processor
|
|
should be quite straight forward, but I do not have an alpha to
|
|
test it on.
|
|
|
|
- Tracing linux binaries is not supported yet, but should be possible
|
|
with some work.
|
|
|
|
- There are some issues with following forks, and only a few FreeBSD
|
|
specific syscalls are decoded right now.
|
|
|
|
- This was tested on FreeBSD 4.0. I believe the tracing interface is
|
|
present since at least FreeBSD 3.0, so it "should" work on all
|
|
latest releases. I have no idea for other BSDs, though.
