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