| 80 | * Irix5 is supported |
| 81 | * Linux 68k is supported |
| 82 | * Linux alpha is supported |
| 83 | * configure is upgraded to autoconf 2.x |
| 84 | * using -f in combination with -e now works correctly |
| 85 | * output can be piped to a program |
| 86 | * tracing setuid programs works better |
| 87 | * it is now reasonable to install strace setuid to root in some circumstances |
| 88 | * new useful tracing names like file and process to trace whole |
| 89 | classes of system calls, e.g. -efile traces all system calls that |
| 90 | take a file name as an argument |
| 91 | * IPC calls on SunOS 4.1.x are decoded |
| 92 | * Linux program memory is reliably dereferenced |
| 93 | * Linux decodes at least the name of all syscalls as of pre2.0.4 |
| 94 | * various cosmetic changes and bug fixes |
| 95 | |
| 96 | Changes from versions 2.x to version 3.0 |
| 97 | ======================================== |
| 98 | |
| 99 | * filename arguments are neither abbreviated nor stringified |
| 100 | * string arguments are now true C strings using octal instead of hex by default |
| 101 | * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY) |
| 102 | * by default the output for multiple processes now goes into one file |
| 103 | * all structures, vectors, bitsets, etc. use consistent output formats |
| 104 | * the -c option now means count calls, -i does what the old -c used to do |
| 105 | |

| 107 | =========================== |
| 108 | |
| 109 | * non-ascii strings can be optionally printed entirely in hex |
