3 * Compiles on glibc2.0 systems again
4 * Linux/S390 port added
5 * The usual Linux syscall updates
9 * Linux/MIPS port added
10 * Lots of Linux updates again
11 * Improved IPv6 support
17 * Compiles on glibc2.0 systems again
21 * Get stat structure properly on Linux 64bit archs
22 * Personalities work again
23 * Compile correctly on SunOS again
29 * Linux (ultra)sparc fixes
36 * add support for more Linux architectures (powerpc, sparc, arm)
37 * support lots more Linux syscalls
39 * add IPX and IPIP support
40 * check stray syscall after execv
41 * fix hanging children
43 Changes in version 3.1
44 ======================
47 * Linux 68k is supported
48 * Linux alpha is supported
49 * configure is upgraded to autoconf 2.x
50 * using -f in combination with -e now works correctly
51 * output can be piped to a program
52 * tracing setuid programs works better
53 * it is now reasonable to install strace setuid to root in some circumstances
54 * new useful tracing names like file and process to trace whole
55 classes of system calls, e.g. -efile traces all system calls that
56 take a file name as an argument
57 * IPC calls on SunOS 4.1.x are decoded
58 * Linux program memory is reliably dereferenced
59 * Linux decodes at least the name of all syscalls as of pre2.0.4
60 * various cosmetic changes and bug fixes
62 Changes from versions 2.x to version 3.0
63 ========================================
65 * filename arguments are neither abbreviated nor stringified
66 * string arguments are now true C strings using octal instead of hex by default
67 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
68 * by default the output for multiple processes now goes into one file
69 * all structures, vectors, bitsets, etc. use consistent output formats
70 * the -c option now means count calls, -i does what the old -c used to do
72 New Features in version 3.0
73 ===========================
75 * non-ascii strings can be optionally printed entirely in hex
76 * the output format is readable when mutiple processes are generating output
77 * exit values are printed in an alignment column
78 * is is possible to suppress messages about attaching and detaching
79 * various tracing features can be enabled on a per syscall/signal/desc basis
80 * selective tracing of syscalls
81 * selective printing of syscall structures
82 * selective abbreviation of long structures on a per syscall basis
83 * selective printing of raw syscall arguments and results
84 * selective tracing of signals
85 * selective dumping of all I/O read from file descriptors
86 * selective dumping of all I/O written to file descriptors
87 * optional counting of time, calls, and errors for each syscall
