4 * add support for more Linux architectures (powerpc, sparc, arm)
5 * support lots more Linux syscalls
7 * add IPX and IPIP support
8 * check stray syscall after execv
11 Changes in version 3.1
12 ======================
15 * Linux 68k is supported
16 * Linux alpha is supported
17 * configure is upgraded to autoconf 2.x
18 * using -f in combination with -e now works correctly
19 * output can be piped to a program
20 * tracing setuid programs works better
21 * it is now reasonable to install strace setuid to root in some circumstances
22 * new useful tracing names like file and process to trace whole
23 classes of system calls, e.g. -efile traces all system calls that
24 take a file name as an argument
25 * IPC calls on SunOS 4.1.x are decoded
26 * Linux program memory is reliably dereferenced
27 * Linux decodes at least the name of all syscalls as of pre2.0.4
28 * various cosmetic changes and bug fixes
30 Changes from versions 2.x to version 3.0
31 ========================================
33 * filename arguments are neither abbreviated nor stringified
34 * string arguments are now true C strings using octal instead of hex by default
35 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
36 * by default the output for multiple processes now goes into one file
37 * all structures, vectors, bitsets, etc. use consistent output formats
38 * the -c option now means count calls, -i does what the old -c used to do
40 New Features in version 3.0
41 ===========================
43 * non-ascii strings can be optionally printed entirely in hex
44 * the output format is readable when mutiple processes are generating output
45 * exit values are printed in an alignment column
46 * is is possible to suppress messages about attaching and detaching
47 * various tracing features can be enabled on a per syscall/signal/desc basis
48 * selective tracing of syscalls
49 * selective printing of syscall structures
50 * selective abbreviation of long structures on a per syscall basis
51 * selective printing of raw syscall arguments and results
52 * selective tracing of signals
53 * selective dumping of all I/O read from file descriptors
54 * selective dumping of all I/O written to file descriptors
55 * optional counting of time, calls, and errors for each syscall
