140 Changes in version 3.1
141 ======================
144 * Linux 68k is supported
145 * Linux alpha is supported
146 * configure is upgraded to autoconf 2.x
147 * using -f in combination with -e now works correctly
148 * output can be piped to a program
149 * tracing setuid programs works better
150 * it is now reasonable to install strace setuid to root in some circumstances
151 * new useful tracing names like file and process to trace whole
152 classes of system calls, e.g. -efile traces all system calls that
153 take a file name as an argument
154 * IPC calls on SunOS 4.1.x are decoded
155 * Linux program memory is reliably dereferenced
156 * Linux decodes at least the name of all syscalls as of pre2.0.4
157 * various cosmetic changes and bug fixes
159 Changes from versions 2.x to version 3.0
160 ========================================
162 * filename arguments are neither abbreviated nor stringified
163 * string arguments are now true C strings using octal instead of hex by default
164 * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY)
165 * by default the output for multiple processes now goes into one file
166 * all structures, vectors, bitsets, etc. use consistent output formats
167 * the -c option now means count calls, -i does what the old -c used to do
169 New Features in version 3.0
170 ===========================
172 * non-ascii strings can be optionally printed entirely in hex
173 * the output format is readable when mutiple processes are generating output
174 * exit values are printed in an alignment column
175 * is is possible to suppress messages about attaching and detaching
176 * various tracing features can be enabled on a per syscall/signal/desc basis
177 * selective tracing of syscalls
178 * selective printing of syscall structures
179 * selective abbreviation of long structures on a per syscall basis
180 * selective printing of raw syscall arguments and results
181 * selective tracing of signals
182 * selective dumping of all I/O read from file descriptors
183 * selective dumping of all I/O written to file descriptors
184 * optional counting of time, calls, and errors for each syscall
