162 Changes in version 3.1
163 ======================
166 * Linux 68k is supported
167 * Linux alpha is supported
168 * configure is upgraded to autoconf 2.x
169 * using -f in combination with -e now works correctly
170 * output can be piped to a program
171 * tracing setuid programs works better
172 * it is now reasonable to install strace setuid to root in some circumstances
173 * new useful tracing names like file and process to trace whole
174 classes of system calls, e.g. -efile traces all system calls that
175 take a file name as an argument
176 * IPC calls on SunOS 4.1.x are decoded
177 * Linux program memory is reliably dereferenced
178 * Linux decodes at least the name of all syscalls as of pre2.0.4
179 * various cosmetic changes and bug fixes
181 Changes from versions 2.x to version 3.0
182 ========================================
184 * filename arguments are neither abbreviated nor stringified
185 * string arguments are now true C strings using octal instead of hex by default
186 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
187 * by default the output for multiple processes now goes into one file
188 * all structures, vectors, bitsets, etc. use consistent output formats
189 * the -c option now means count calls, -i does what the old -c used to do
191 New Features in version 3.0
192 ===========================
194 * non-ascii strings can be optionally printed entirely in hex
195 * the output format is readable when mutiple processes are generating output
196 * exit values are printed in an alignment column
197 * is is possible to suppress messages about attaching and detaching
198 * various tracing features can be enabled on a per syscall/signal/desc basis
199 * selective tracing of syscalls
200 * selective printing of syscall structures
201 * selective abbreviation of long structures on a per syscall basis
202 * selective printing of raw syscall arguments and results
203 * selective tracing of signals
204 * selective dumping of all I/O read from file descriptors
205 * selective dumping of all I/O written to file descriptors
206 * optional counting of time, calls, and errors for each syscall
