I have released version 3.36 of UPS. It is currently available on the following
servers, and will propagate to others in the next few days.
ftp://ftp.x.org/contrib/utilities/
ftp://ftp.cs.ubc.ca/pub/mirror/x-contrib/utilities/
ftp://sunsite.doc.ic.ac.uk/packages/X11-contrib/utilities/
(I think Ian is on holiday, so it's not on the UPS web site yet, but
will be soon.)
This is from the CHANGES file:
Changes between 3.36 and 3.35
-----------------------------
o 3.36 has been used on Solaris 2.x, SunOS 4.3.1 and Linux Debian 2.0.34 only.
Being based on 3.35, it should be possible to build it on Solaris 8,
FreeBSD 3.2, FreeBSD 4.0 and RedHat Linux 6.2.
o The changes to ups make it more versatile and faster to use. It will
continue to work as before, but for large targets, it is more efficient
to load just a few standard libraries and load others on the fly as
needed. This can be done with a ".upsinit" file in your home directory.
An example is:
load *libc.so*
load *libC.so*
load /usr/lib/lib*
load /usr/openwin/*
load /usr/platform/*
load /usr/dt/lib/*
# for target specific libraries:
load ./*
load ../*
You might want to edit this to always load certain libraries, and add
source paths with the "use" command, but now there should be little need
to deal with this file as libraries can be easliy loaded interactively.
By using "load" rather than "noload", ups won't be affected by different
sets of libraries that each target may have.
Note that "./" now has the meaning of the directory of the target, not of
where ups was started.
o By only loading the minimum standard libraries, ups will start a
lot faster. Other libraries can be loaded on the fly by selecting
"Target", then "Load library", which will display a menu of unloaded
libraries - simply choose one to load it. Similarly, the stack trace will
display <full library name> for an unloaded library. To load it, select
the line and press "Load library". As always for objects in the display
window, multiple objects in the stack can be selected at once, and
loaded as a group.
The full set of libraries that the target uses is determined
after the target has been started or attached to, so the "Load library"
list will change at that point.
o Ups is now persistent - that is, it can be kept running for weeks
like an editor, with no need to exit at the end of each debug
session. The top line of the "Target" line can be edited to a
different name, and ups will read new symbols as necessary and
reinstate breakpoints and variables as possible. So if you are
working on a shared library, and you need to test it with
different targets, simply enter the new target name and
attach, and the debug state information will be preserved.
(The unimplemented "Write target core" was changed to "Load library").
The target name accepts csh style tilde notation.
Similarly, one can continue to debug code that gets built each
night by a nightly build: detach before the rebuild, then
reattach afterwards and ups will read any newly built libraries and
restore the debug state. There should no longer be problems with
reverse video caused by the debugger not updating its symbol information.
o It is now easier to use ups to examine code. Left clicking
on a function name in an active function causes ups to read the
function symbols before navigating to the function. You can bypass
the symbol reading by using the middle mouse button. So an
unmodified left click looks up local symbols, then globals, a
shift-left click does an automatic "add expr", and a middle click,
if not over breakpoint code, looks up global symbol lookup only.
o Fixed a refresh bug when using CDE with "click to focus" and "raise on
focus" - ups now repaints properly when it receives focus.
o Changed the submenu order when loading breakpoint files so that the default
is to save the breakpoints to the statefile.
o Changes from Terry R. Friedrichsen <terry_at_venus.sunquest.com>
- Fixes for building on Red Hat Linux 7.0
o Changes from Russ Browne <russ_at_amc.com>
- Changes to the menu editor (med3) to produce readable output.
o There are new X resources for the "Load library" menu invoked from the target
line: UnloadedLibMenuForeground and UnloadedLibMenuBackground.
Caveat
======
This hasn't had as much testing as I would like. There are some leaks in
memory and file descriptors in some debug scenarios when one switches
a lot between targets within one debug session. Breakpoints don't always get
cleaned up or reinstated properly when switching targets. Please post fixes as
you find them.
