150 Changes in version 3.1
151 ======================
154 * Linux 68k is supported
155 * Linux alpha is supported
156 * configure is upgraded to autoconf 2.x
157 * using -f in combination with -e now works correctly
158 * output can be piped to a program
159 * tracing setuid programs works better
160 * it is now reasonable to install strace setuid to root in some circumstances
161 * new useful tracing names like file and process to trace whole
162 classes of system calls, e.g. -efile traces all system calls that
163 take a file name as an argument
164 * IPC calls on SunOS 4.1.x are decoded
165 * Linux program memory is reliably dereferenced
166 * Linux decodes at least the name of all syscalls as of pre2.0.4
167 * various cosmetic changes and bug fixes
169 Changes from versions 2.x to version 3.0
170 ========================================
172 * filename arguments are neither abbreviated nor stringified
173 * string arguments are now true C strings using octal instead of hex by default
174 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
175 * by default the output for multiple processes now goes into one file
176 * all structures, vectors, bitsets, etc. use consistent output formats
177 * the -c option now means count calls, -i does what the old -c used to do
179 New Features in version 3.0
180 ===========================
182 * non-ascii strings can be optionally printed entirely in hex
183 * the output format is readable when mutiple processes are generating output
184 * exit values are printed in an alignment column
185 * is is possible to suppress messages about attaching and detaching
186 * various tracing features can be enabled on a per syscall/signal/desc basis
187 * selective tracing of syscalls
188 * selective printing of syscall structures
189 * selective abbreviation of long structures on a per syscall basis
190 * selective printing of raw syscall arguments and results
191 * selective tracing of signals
192 * selective dumping of all I/O read from file descriptors
193 * selective dumping of all I/O written to file descriptors
194 * optional counting of time, calls, and errors for each syscall
