| Changes in 4.4.96 TEST release |
| ============== |
| * New port to AMD's x86-64 architecture. One strace binary can |
| handle both new x86-64 and old i386 processes. |
| * Fixed support for LFS64 calls. |
| * New switch -E to add/remove environment variables for the command. |
| * Merged s390/s390x port. |
| * Trace an unbounded number of processes. |
| * Handle numerous new system calls in Linux 2.5, and new threads semantics. |
| * Fixed bugs with attach/detach leaving things stopped. |
| * Fixed traced process seeing ECHILD despite live, traced children |
| in waitpid calls with WNOHANG. |
| * Stuart Menefy contributed a port to Linux/SH. |
| |
| Changes in 4.4 |
| ============== |
| * Fix Linux/ia64 support, looks like someone renamed a few things on us |
| * Fix the ioctl setup for Linux, turned out it did not really work. |
| Improve the ioctl extracter as well so we decode some more ones. |
| |
| Changes in 4.3.1 |
| ================ |
| * compile fixes for Linux/mips |
| |
| Changes in 4.3 |
| ============== |
| * Linux ia64 and hppa ports added |
| * The usual Linux syscall updates (includes 32bit uid/gid support), |
| * Linux ioctl list updated |
| * Support IPv6 scope ids |
| * FreeBSD/i386 port added |
| * UnixWare and Solaris updates |
| * Better support for tracing multithreaded processes in Linux |
| |
| Changes in 4.2 |
| ============== |
| * Compiles on glibc2.0 systems again |
| * Linux/S390 port added |
| * The usual Linux syscall updates |
| * we can follow fork on arm now |
| |
| Changes in 4.1 |
| ================ |
| * Linux/MIPS port added |
| * Lots of Linux updates again |
| * Improved IPv6 support |
| * Add strace-graph |
| |
| Changes in 4.0.1 |
| ================ |
| * Minor bugfixes |
| * Compiles on glibc2.0 systems again |
| |
| Changes in 4.0 |
| ============== |
| * Get stat structure properly on Linux 64bit archs |
| * Personalities work again |
| * Compile correctly on SunOS again |
| * IRIX64 updates |
| * Solaris updates |
| |
| Changes in 3.99.1 |
| ================= |
| * Linux (ultra)sparc fixes |
| * Linux alpha fixes |
| * Minor cleanups |
| |
| Changes in 3.99 |
| =============== |
| * New maintainer |
| * add support for more Linux architectures (powerpc, sparc, arm) |
| * support lots more Linux syscalls |
| * fix signal handling |
| * add IPX and IPIP support |
| * check stray syscall after execv |
| * fix hanging children |
| |
| Changes in version 3.1 |
| ====================== |
| |
| * Irix5 is supported |
| * Linux 68k is supported |
| * Linux alpha is supported |
| * configure is upgraded to autoconf 2.x |
| * using -f in combination with -e now works correctly |
| * output can be piped to a program |
| * tracing setuid programs works better |
| * it is now reasonable to install strace setuid to root in some circumstances |
| * new useful tracing names like file and process to trace whole |
| classes of system calls, e.g. -efile traces all system calls that |
| take a file name as an argument |
| * IPC calls on SunOS 4.1.x are decoded |
| * Linux program memory is reliably dereferenced |
| * Linux decodes at least the name of all syscalls as of pre2.0.4 |
| * various cosmetic changes and bug fixes |
| |
| Changes from versions 2.x to version 3.0 |
| ======================================== |
| |
| * filename arguments are neither abbreviated nor stringified |
| * string arguments are now true C strings using octal instead of hex by default |
| * preprocessor constants are never shortened (e.g. was RDONLY => now O_RDONLY) |
| * by default the output for multiple processes now goes into one file |
| * all structures, vectors, bitsets, etc. use consistent output formats |
| * the -c option now means count calls, -i does what the old -c used to do |
| |
| New Features in version 3.0 |
| =========================== |
| |
| * non-ascii strings can be optionally printed entirely in hex |
| * the output format is readable when mutiple processes are generating output |
| * exit values are printed in an alignment column |
| * is is possible to suppress messages about attaching and detaching |
| * various tracing features can be enabled on a per syscall/signal/desc basis |
| * selective tracing of syscalls |
| * selective printing of syscall structures |
| * selective abbreviation of long structures on a per syscall basis |
| * selective printing of raw syscall arguments and results |
| * selective tracing of signals |
| * selective dumping of all I/O read from file descriptors |
| * selective dumping of all I/O written to file descriptors |
| * optional counting of time, calls, and errors for each syscall |
