The 3.37-beta4 version of UPS is now available from: http://www.concerto.demon.co.uk/UPS/src/ups-3.37-beta4.tar.gz Thanks to Tom Hughes for providing the bulk of the changes for this release. Changes between 3.37-beta4 and 3.37-beta3 ----------------------------------------- Enhancements from Tom Hughes <thh_at_cyberscience.com>: o Double clicking on a variable in the source window expands or compresses the structure as it does in the display window. So you can select and dereference a pointer or struct without having to move up to the stack display. o Functions in the target process can be called from expressions in the stack display. o Extends the canonicalisation of integer type names to cover long long as well as the other integer types. o Fix for parameters which have to be widened when passed from appearing twice in the stack frame - gcc on linux adds two stabs for these, one for the actual type in the parameter and one for the widened form used when it is passed. o Ups saves the terminal state on startup and restore it on exit and when restarting the target process. This ensures that if the application being debugged changes the terminal state and then exits or is killed before restoring it the terminal is put back in a sane state. o Fix for a crash when dealing with void types with gcc on linux. o Optimized the redraw routines by using clipping so that ups doesn't flicker like mad when you drag a window across it. o Fix for single stepping across shared library boundaries on x86 machines. o Ups checks the dynamic linker cache when it is trying to work out which shared library will be used. Without this it was getting confused about which C library was being used because it wasn't implementing the same search rules as the dynamic linker. The patch also implements DT_RUNPATH (for those systems that support it) from the dynamic section in addition to DT_RPATH so that the search rules should now exactly match those given in the linux manual page for the dynamic linker. o Allows main() to be in a shared library. o Fix for x86 machines to allow backtraces to be generated even when functions do not have frame pointers by searching back through the stack for plausible return addresses that appear to point after call instructions. o Fix to deal with the fact that linux does not provide signal handler information in the ptrace user area by looking in /proc for it instead. This means that ups will correctly stop when it encounters a segv and the target process has not got a handler installed for it. This also allows ups to stop on any signal which we have asked to stop on, even if we were single stepping when it was caught. Changes from Rod Armstrong <rod_at_san-jose.tt.slb.com>: o Allowed a double click on a variable in the source window to alternately expand or compress the variable, just as it does in the display window. o Extended the use of the repltab file for all expressions, not just those automatically pasted from the source window. In addition, if a ./ups-state/repltab files does not exist, ups looks for $HOME/repltab as well. If a repltab file is found ups does replacements as specified in the file for text of expressions. See the man pages for details. A simple repltab file is: NULL 0 FALSE 0 TRUE 1 o Eliminated the messages at invocation for loading stripped libraries ("Warning: no .symtab section ... using .dynsym instead"). The messages still appear when loading libraries interactively. o Various fixes to allow ups to survive bad code in expressions, particularly when calling functions. Changes from Ian Edwards <ian_at_concerto.demon.co.uk> o Added some RCS identifier strings. o Changes to method of creating spec. file for RPMs. o Changes to ups/ao_stack.c to allow it to build on FreeBSD. Changes from Russ Browne <russ_at_amc.com> o Fixes for the new clipping routines to allow the correct display of menus. o Added check for __SIGRTMIN in order to display an extended list of signals on Linux.
