| Wichert Akkerman | 76baf7c | 1999-02-19 00:21:36 +0000 | [diff] [blame] | 16 | Changes in version 3.1 |
| 17 | ====================== |
| 18 | |
| 19 | * Irix5 is supported |
| 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 |
| 34 | |
| 35 | Changes from versions 2.x to version 3.0 |
| 36 | ======================================== |
| 37 | |
| 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 |
| 44 | |
| 45 | New Features in version 3.0 |
| 46 | =========================== |
| 47 | |
| 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 |
