| 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. |
