Operating system and Hardware
PureCoverage has been tested with HP-UX versions 10.01, 10.10, 10.20, and 11.00 from Hewlett Packard.
This is the last release to support HP-UX versions 10.01 and 10.10.
Compilers
PureCoverage has been tested with the following compilers:
See the "Restrictions and Known Issues" section for more details.
Threads
PureCoverage supports these threads packages:
General
This change was made due to a problem in HP dld patches from June 1998 for HPUX 11.00 and August 1998 for HP-UX 10.20, which caused the instrumented application to hang after a call to shl_load(). One known instance of this problem occurs when you use getservbyname() because it loads network protocols using shl_load().
Linker and dld patches available after 3/99 don't have this problem. If the user has an earlier patch, an upgrade is strongly recommended.
-dlclose-mode=0 (default for earlier releases) libraries may not be unmapped.
-dlclose-mode=1 (default for PureCoverage 4.0) libraries may be unmapped.
-dlclose-mode=2 libraries may be unmapped, coverage data is saved just prior to unmapping.
Error: Child process exited with status = 1.
This is caused by an 'ar' failure in this locale. A workaround is to unsetenv LANG before instrumenting.
User Interface
! Ignore the NumLock and ScrollLock keys on ! mouse buttons PureCoverage*ignoreModifierMask: Mod3|Mod2
This second workaround will take effect for a new PureCoverage viewer after you restart your X-session or run a command like 'xrdb -merge $HOME/.Xdefaults'.
The site-wide URL for ClearQuest can be given during installation or set by manually editting the file
pure_clearquest_url
in your PureCoverage home directory. A user can override the site-wide URL by setting the environment variable
PURE_CLEARQUEST_URL
This feature is partly implemented by a shell script, ("pure_invoke_clearquest" in your PureCoverage home directory) to allow you to tailor its operation to your needs. If you wish, you may copy and customize this. script. As long as the directory containing the script appears in your search path before your PureCoverage home directory, it will be used instead of the original script.
If you prefer to use PureCoverage with ClearDDTS, you can do so by setting the X resource:
PureCoverage*ddtsCommandString
to 'xddts', if xddts is in your search path, or to the full path to your xddts executable. xddts is invoked by a shell script ("pure_invoke_ddts" in your PureCoverage home directory). If you wish to customize it, please read the section on customizing "pure_invoke_clearquest" above.
If you already have a customized "pure_invoke_ddts" script in your search path, All you need to do is set your X resource as described above, and PureCoverage will find your customized script automatically.

Compilers

Debuggers
Wait...loading shared-library map tables. xdb panic: Mapped addresses for dld overlap text segment for dld
There is a simple workaround for this problem and we've implemented it in the shell script <purecovhome>/purecov_xdb. Whenever you use xdb on an instrumented program use this script to invoke xdb.

Old Style Fixups
PureCoverage does not support a type of relocation information known as "old style fixups". These were generated by HP-UX system software before release 3.0. If PureCoverage detects old style fixups the message: Object file has incompatible format (may be older than HPUX 3.0) is generated. We have seen this problem with HP's libsql.a and some of Oracle's Oracle6 libraries.
There is a simple workaround. Given a problem object module (or modules) the workaround is to have /bin/ld build a new object module. Suppose the old object modules are called `foo.o' and `bar.o'. Issuing the command: % ld -r -o new_foo.o foo.o % ld -r -o new_bar.o bar.o or % ld -r -o foo_and_bar.o foo.o bar.o would generate a new object module where the old style fixups have been removed.
In the case of an archive file the following script will create a new archive given the full pathname of the original:
#!/bin/sh
# Remove old fixups from an archive.
# Supply original .a name as first argument.
cd /tmp
lib=new_`basename $1`
ar x $1
rm -f $lib
for member in `ar t $1` ; do
ld -r -o _$member $member
ar q $lib _$member
rm $member _$member
done
echo Created `pwd`/$lib
