3 * Get stat structure properly on Linux 64bit archs
4 * Personalities work again
5 * Compile correctly on SunOS again
11 * Linux (ultra)sparc fixes
18 * add support for more Linux architectures (powerpc, sparc, arm)
19 * support lots more Linux syscalls
21 * add IPX and IPIP support
22 * check stray syscall after execv
23 * fix hanging children
25 Changes in version 3.1
26 ======================
29 * Linux 68k is supported
30 * Linux alpha is supported
31 * configure is upgraded to autoconf 2.x
32 * using -f in combination with -e now works correctly
33 * output can be piped to a program
34 * tracing setuid programs works better
35 * it is now reasonable to install strace setuid to root in some circumstances
36 * new useful tracing names like file and process to trace whole
37 classes of system calls, e.g. -efile traces all system calls that
38 take a file name as an argument
39 * IPC calls on SunOS 4.1.x are decoded
40 * Linux program memory is reliably dereferenced
41 * Linux decodes at least the name of all syscalls as of pre2.0.4
42 * various cosmetic changes and bug fixes
44 Changes from versions 2.x to version 3.0
45 ========================================
47 * filename arguments are neither abbreviated nor stringified
48 * string arguments are now true C strings using octal instead of hex by default
49 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
50 * by default the output for multiple processes now goes into one file
51 * all structures, vectors, bitsets, etc. use consistent output formats
52 * the -c option now means count calls, -i does what the old -c used to do
54 New Features in version 3.0
55 ===========================
57 * non-ascii strings can be optionally printed entirely in hex
58 * the output format is readable when mutiple processes are generating output
59 * exit values are printed in an alignment column
60 * is is possible to suppress messages about attaching and detaching
61 * various tracing features can be enabled on a per syscall/signal/desc basis
62 * selective tracing of syscalls
63 * selective printing of syscall structures
64 * selective abbreviation of long structures on a per syscall basis
65 * selective printing of raw syscall arguments and results
66 * selective tracing of signals
67 * selective dumping of all I/O read from file descriptors
68 * selective dumping of all I/O written to file descriptors
69 * optional counting of time, calls, and errors for each syscall
