See ltrace(1) for details. + + - ltrace.conf is no longer part of installation tarball. Instead, + we now ship libc.so.conf, libm.so.conf, libacl.so.conf, and + syscalls.conf. Those are now istalled to /usr/share/ltrace by + default. /etc/ltrace.conf and $HOME/.ltrace.conf are still + loaded if present, and can contain arbitrary user configuration. + + - The option -F was retrofitted to be a colon-separated list of + prototype libraries, and directories to look for prototype + libraries in. On Linux, ltrace looks into XDG_CONFIG_HOME, + XDG_CONFIG_DIRS, and /usr/share/ltrace as well. + + - Wide character strings are supported in prototypes. Use "string" + lens as usual, but use array of integers as underlying type. + libc.so.conf now contains prototypes of wide character functions. + + - Sole void function parameter such as in the following example, is + now considered obsolete: + + | int fork(void); | + + This use is still accepted, taken to mean "hide(int)", but + produces a warning, and will be removed in future. + + - Prototypes are now read from DWARF debug info, if available. This + complements the data available in config files + +** Architectural support + - MIPS and MIPSel are now handled by the same backend. + - ARMv6, ARMv7 and ARMv8 (AArch64) are supported, including full + fetch backend. ARMv8 backend doesn't support tracing of 32-bit + binaries, as currently there's no 32-bit userspace available for + ARM64 processors. + - Imagination Technologies Meta is now supported. + - PowerPC64 ELFv2 little-endian ABI is now supported including full + fetch backend. + + - On Linux, tracing of IFUNC symbols is supported. On i386, + x86_64, ppc32 with secure PLT and ppc64, IRELATIVE PLT slots are + traced as well. + +** -w output now shows full library path + The output format is similar to glibc's backtrace_symbols, e.g.: + > /bin/ls(_init+0x19be) [0x40398e] + > /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xed) [0x7f50cbc3676d] + > /bin/ls(_init+0x25fd) [0x4045cd] + +* Version 0.7.3 [2013-09-15 Sun] +** Bugfixes +*** [MIPS] Fix build on mips big endian + This bug caused messages like: + | Making all in mips + | /bin/sh: line 17: cd: mips: No such file or directory +*** [MIPS] Fix SIGSEGV on mips big endian + This bug caused runtime messages like: + | [0x4000000] --- SIGSEGV (Segmentation fault) --- + | [0xffffffff] +++ killed by SIGSEGV +++ +*** Fix build with CLANG on FREEBSD + * Version 0.7.2 [2012-12-07 Fri] ** Bugfixes *** (Again) detect VDSO entry in r_debug linkmap with non-empty name @@ -286,7 +350,7 @@ * License ------------------------------------------------------------------------------- -Copyright (C) 2012 Petr Machata <pmachata@redhat.com> +Copyright (C) 2012-2014 Petr Machata <pmachata@redhat.com> This file is part of ltrace. ltrace is free software; you can redistribute it and/or modify it |
