3 * Compiles on glibc2.0 systems again
4 * Linux/S390 port added
5 * The usual Linux syscall updates
6 * we can follow fork on arm now
10 * Linux/MIPS port added
11 * Lots of Linux updates again
12 * Improved IPv6 support
18 * Compiles on glibc2.0 systems again
22 * Get stat structure properly on Linux 64bit archs
23 * Personalities work again
24 * Compile correctly on SunOS again
30 * Linux (ultra)sparc fixes
37 * add support for more Linux architectures (powerpc, sparc, arm)
38 * support lots more Linux syscalls
40 * add IPX and IPIP support
41 * check stray syscall after execv
42 * fix hanging children
44 Changes in version 3.1
45 ======================
48 * Linux 68k is supported
49 * Linux alpha is supported
50 * configure is upgraded to autoconf 2.x
51 * using -f in combination with -e now works correctly
52 * output can be piped to a program
53 * tracing setuid programs works better
54 * it is now reasonable to install strace setuid to root in some circumstances
55 * new useful tracing names like file and process to trace whole
56 classes of system calls, e.g. -efile traces all system calls that
57 take a file name as an argument
58 * IPC calls on SunOS 4.1.x are decoded
59 * Linux program memory is reliably dereferenced
60 * Linux decodes at least the name of all syscalls as of pre2.0.4
61 * various cosmetic changes and bug fixes
63 Changes from versions 2.x to version 3.0
64 ========================================
66 * filename arguments are neither abbreviated nor stringified
67 * string arguments are now true C strings using octal instead of hex by default
68 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
69 * by default the output for multiple processes now goes into one file
70 * all structures, vectors, bitsets, etc. use consistent output formats
71 * the -c option now means count calls, -i does what the old -c used to do
73 New Features in version 3.0
74 ===========================
76 * non-ascii strings can be optionally printed entirely in hex
77 * the output format is readable when mutiple processes are generating output
78 * exit values are printed in an alignment column
79 * is is possible to suppress messages about attaching and detaching
80 * various tracing features can be enabled on a per syscall/signal/desc basis
81 * selective tracing of syscalls
82 * selective printing of syscall structures
83 * selective abbreviation of long structures on a per syscall basis
84 * selective printing of raw syscall arguments and results
85 * selective tracing of signals
86 * selective dumping of all I/O read from file descriptors
87 * selective dumping of all I/O written to file descriptors
88 * optional counting of time, calls, and errors for each syscall
