167 Changes in version 3.1
168 ======================
171 * Linux 68k is supported
172 * Linux alpha is supported
173 * configure is upgraded to autoconf 2.x
174 * using -f in combination with -e now works correctly
175 * output can be piped to a program
176 * tracing setuid programs works better
177 * it is now reasonable to install strace setuid to root in some circumstances
178 * new useful tracing names like file and process to trace whole
179 classes of system calls, e.g. -efile traces all system calls that
180 take a file name as an argument
181 * IPC calls on SunOS 4.1.x are decoded
182 * Linux program memory is reliably dereferenced
183 * Linux decodes at least the name of all syscalls as of pre2.0.4
184 * various cosmetic changes and bug fixes
186 Changes from versions 2.x to version 3.0
187 ========================================
189 * filename arguments are neither abbreviated nor stringified
190 * string arguments are now true C strings using octal instead of hex by default
191 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
192 * by default the output for multiple processes now goes into one file
193 * all structures, vectors, bitsets, etc. use consistent output formats
194 * the -c option now means count calls, -i does what the old -c used to do
196 New Features in version 3.0
197 ===========================
199 * non-ascii strings can be optionally printed entirely in hex
200 * the output format is readable when mutiple processes are generating output
201 * exit values are printed in an alignment column
202 * is is possible to suppress messages about attaching and detaching
203 * various tracing features can be enabled on a per syscall/signal/desc basis
204 * selective tracing of syscalls
205 * selective printing of syscall structures
206 * selective abbreviation of long structures on a per syscall basis
207 * selective printing of raw syscall arguments and results
208 * selective tracing of signals
209 * selective dumping of all I/O read from file descriptors
210 * selective dumping of all I/O written to file descriptors
211 * optional counting of time, calls, and errors for each syscall
