I have relesed the 3.33 version of UPS. This should fix the disappearing
breakpoints problem reported by Callum Gibson. It has some neat C++
support as contributed by Russ Browne, as well as the fixes included in
the 3.32.1 patch. Mark Russell rightly pointed out the correct form of
the errf() call. I'll fix on the next release.
A caveat from Ian Edwards:
There may have to be a 3.34 in a few weeks/months though - UPS will build
on FreeBSD 3.0 but does not work because the registers cannot be accessed
through the 'u area' any longer, there being new 'ptrace()' calls to
get and set registers : PTRACE_GETREGS and PTRACE_SETREGS.
Updated releases of UPS
-----------------------
This version has only been compiled and tested on Solaris 2.5,
Solaris 2.6 and SunOS 4.1.3, with the Sparc Compilers SC4 and
SC4.2, gcc/g++ 2.7.2, and the Centerline c and cfront/C++
compilers. Also built for Linux ELF 2.0.31 (Red Hat 5.0).
See the file README for build instructions.
The URL for the ups web site is:
http://www.concerto.demon.co.uk/UPS/
It is maintained by Ian Edwards (ian_at_concerto.demon.co.uk).
It includes a FAQ, html man pages, site listings where ups
can be found, supported architectures, a history of changes
between versions, and other information.
Getting the release
-------------------
The README and tar file are available from:
ftp://ftp.x.org/contrib/utilities/ups-3.33.README
ftp://ftp.x.org/contrib/utilities/ups-3.33.tar.gz
The same site has precompiled binaries for Solaris, SunOS and Linux 2.0.31.
Note that these are NOT tar files, just compressed binaries - so simply unzip
them with "gzip -d" and rename to "ups".
ftp://ftp.x.org/contrib/utilities/ups-3.33-solaris-2.6.gz
ftp://ftp.x.org/contrib/utilities/ups-3.33-solaris-2.5.1.gz
ftp://ftp.x.org/contrib/utilities/ups-3.33-sunos-4.1.3.gz
ftp://ftp.x.org/contrib/utilities/ups-3.33-linux-2.0.31.gz
All the files are available at other mirror sites such as:
ftp://sunsite.unc.edu/pub/X11/contrib/utilities
ftp://ftp.cs.ubc.ca/pub/mirror/x-contrib/utilities
ftp://ftp.funet.fi/pub/X11/contrib/utilities
ftp://ftp.sunet.se/pub/X11/contrib/utilities
ftp://sunsite.doc.ic.ac.uk/packages/X11-contrib/utilities
(It's not yet available at unix.hensa.ac.uk, but should be later.)
Unpacking the distribution
--------------------------
You should have a compressed tar file called ups-3.33.tar.gz Change
directory to a disk with a six or more megabytes of free space and say:
gzip -dc ups-3.33.tar | tar xfp -
This will create a directory tree called ups-3.33. Change directory into it.
See the file README for build instructions.
Changes between 3.33 and 3.32-RGA
-------------------------------------
Russ Browne <russ_at_amc.com> added handling of symbol table information
concerning base classes, vector tables, and static class members in
SC4 and g++ object files. This results in the following family of
features, most of which work only for the above two compilers:
o Base classes are displayed as structs within the structure,
similar to ddd or Visual C++.
o Static members of a class may be examined in a way consistent
with the UPS methods for examining of global data ( e.g. click
on "myClass::statMem", or for examining members of a struct
(e.g. select an object of type myClass* then enter ".statMem"
in the typing line, or click on "statMem" inside a NON-static
method for myClass to get this->statMem).
o Added a popup menu option to expand all static members of a
selected object.
He also:
o Moved the determination of the compiler to the initial load of the symbol
table instead of the parsing of type information. This should remove the
need for the UPS_COMPILER environment variable as a workaround for when
the previous algorithm failed. Also, the compiler is correctly identified
before it is needed during demangling.
o Fixed some ommisions in the demangling. ( Gnu distructors demangled
as A::_ instead of A::~A; for SC4, operator*= and operator%= demangled
as operator-=; for SC4 and clcc, cast operators demangled incorrectly.)
o Added handling of template type names in g++ symbol tables.
o Put up a blocking cursor (hourglass) during symbol table parsing as
version 2.XX did.
o Corrected "Unknown PT_NOTE type " message that
came up when loading an ELF core file.
o Various fixes to better read static variables, both local and global,
for SC4 code.
o Improvements to handle optimized code. This should result in being able
to set breakpoints on the open brace of functions in optimized code,
and result in the stack trace when you break in optimized code (or
get a core file for one), showing all optimized functions as being
at their opening brace. Better than not shown at all.
o Corrected the following in 3.32:
Default colors for "HighlightColor" and "VariableColor" failed
if these X resources were not set.
Using the typing line shortcut to do a search then shifting
to the search button in the menus to continue the search
dumped core.
With g++ version 2.6 and earlier, variables of type bool
could incorrectly display as true.
o Jody Goldberg <jodygold_at_sanwafp.COM> contributed a small fix for
the hashtable growing algorithm. This addresses a failure on large
C++ programs under Solaris-2.5.1
Rod Armstrong added:
o Fix to allow debug of a target that is completely statically linked.
o Fix for cleaning up the temporary breakpoint file that UPS creates
when re-attaching to a different instance of a process.
o Fix so that that when multiple instances of local or global variables
are displayed (by using the duplicate option for instance), all
such instances are restored when the function is re-enetered.
Previously only one instance was restored.
o Updated the man pages and online help text.
o Added the source for the med3 menu editor. The old sources were made
ansi compliant, and the editor now reads and writes the expanded menu
structures that include the foreground and background colors that
were introduced in UPS version 3.32. The med3 sources are in the
ups-3.33/med3 directory. There is documentation in ups-3.33/med3/doc.
Med3 was written by John Bovey, UKC, 26-4-93, who also did most of
the development of the wn library. Med3 links with the wn library in
the UPS distribution. I restored the autonomy of the this library by
replacing all hardcorded calls to other ups functions with callbacks.
The following were in the 3.32.1 patch and are included in 3.33
---------------------------------------------------------------
o Fixed the problem of finding source files for targets that are relatively
linked. This bug was introduced in the 3.32 version, and only appeared
for certain combinations of compilers and source.
o Fixed the menu colors for the "*" menu item for variables. There is
now a special Asterisk resource for this. See the man pages for details.
o Fix for finding symbol table information in library object files produced by
the SC4 compiler, that are statically linked into the target.
o The temporary file that ups uses to re-establish breakpoints on
reattaching to a target is now named with a PID number, and removed
after use. This fixes possible file conflicts between different users
on the same machine.
o Fixed a crash reported by Bob Carragher <bob_at_fla.fujitsu.com> caused by
an old state file that referred to a data structure that had since changed.
o A left click on a block in the stack (the line that shows the line
ranges for the block) now displays the source, instead of expanding the
block.
o Fixed inefficient repaints for target menu, and made the stop button
active during all symbol table reading.
Incorporated patches from Ian Edwards <ian_at_panorama.com> for:
o Fixing build problems with FreeBSD 2.2.6-STABLE (also thanks to
Terry R. Friedrichsen <terry_at_venus.sunquest.com>).
o This also restores the ability to call target functions from breakpoint
code. Should work for Linux as well.
o Fix for FreeBSD in which doing 'Stop', 'Kill', 'Start' caused
"Fatal internal error: shared lib botch (aborting) ...".
o FreeBSD - when debugging a core file UPS now reports the signal that
caused the core dump, and the stack trace includes symbols that are
in shared libraries.
o General - can now edit long long integers. Tested on FreeBSD 2.2.6-STABLE
and Solaris 2.
