| Changes in version 3.1 |
| ====================== |
| |
| * Irix5 is supported |
| * Linux 68k is supported |
| * Linux alpha is supported |
| * configure is upgraded to autoconf 2.x |
| * using -f in combination with -e now works correctly |
| * output can be piped to a program |
| * tracing setuid programs works better |
| * it is now reasonable to install strace setuid to root in some circumstances |
| * new useful tracing names like file and process to trace whole |
| classes of system calls, e.g. -efile traces all system calls that |
| take a file name as an argument |
| * IPC calls on SunOS 4.1.x are decoded |
| * Linux program memory is reliably dereferenced |
| * Linux decodes at least the name of all syscalls as of pre2.0.4 |
| * various cosmetic changes and bug fixes |
| |
| Changes from versions 2.x to version 3.0 |
| ======================================== |
| |
| * filename arguments are neither abbreviated nor stringified |
| * string arguments are now true C strings using octal instead of hex by default |
| * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY) |
| * by default the output for multiple processes now goes into one file |
| * all structures, vectors, bitsets, etc. use consistent output formats |
| * the -c option now means count calls, -i does what the old -c used to do |
| |
| New Features in version 3.0 |
| =========================== |
| |
| * non-ascii strings can be optionally printed entirely in hex |
| * the output format is readable when mutiple processes are generating output |
| * exit values are printed in an alignment column |
| * is is possible to suppress messages about attaching and detaching |
| * various tracing features can be enabled on a per syscall/signal/desc basis |
| * selective tracing of syscalls |
| * selective printing of syscall structures |
| * selective abbreviation of long structures on a per syscall basis |
| * selective printing of raw syscall arguments and results |
| * selective tracing of signals |
| * selective dumping of all I/O read from file descriptors |
| * selective dumping of all I/O written to file descriptors |
| * optional counting of time, calls, and errors for each syscall |
