This
file contains descriptions of noteworthy problems found in and not yet resolved
in ClearCase LT Version 2002.05.00. Any functionality or characteristics described
here that refers to ClearCase applies
to ClearCase LT as well. Note: The ClearCase Product Family development
group switched to a new change request system after ClearCase 4.0 was released.
ID numbers differ between the old and new systems. This document lists both
numbers. The new number appears first and includes a CMBU prefix. The former
four- or five-digit number, if one exists, appears in parentheses. Known
Problems in This Release
The
following are the known problems in ClearCase LT Version 2002.05.00. #CMBU00002462 (#7328) permissions problem building over winked-in derived
object
When
your build script builds over a target without first removing it, the script
must retain the permissions of the built-over DO. Your view maintains these
permissions correctly, but the data container created by the MVFS gets new,
potentially different permissions. As a result, subsequent attempts to build
over the target may fail. #CMBU00010087 (#11485) grp files do not handle multibyte characters
xclearcase may fail with grp files using the Shift-JIS (SJIS)
Japanese character encoding. xclearcase does not correctly discriminate between
the second byte of some shift JIS characters (which are in hexadecimal code
0x5c) and the ASCII code for backslash (\). #CMBU00021475
(#24196) some applications may require increase in size of data limits
On
computers configured with a per-process data size limit of 16 MB, certain
applications, including some of ClearCase GUI programs and some HyperHelp
online help files, may run out of memory and display errors. In
addition, some GUI programs may not work with some older versions of X Windows/CDE. #CMBU00026201 (#29379), (#26909), (#30185) global types: differences
in command line behavior and GUI behavior
The ClearCase Type Explorer and Properties
Browser always display information about local copies of global types, instead
of displaying information about the global type. If
the client VOB you are browsing does not contain a local copy of a global
type, the ClearCase Type Explorer does not display the global type. #CMBU00028068 (#31461) diffbl does not work with imported baselines
The cleartool diffbl command,
which compares two baselines and shows the differences between them, does
not work correctly when one or both of the baselines are imported baselines. #CMBU00028214 (#31626) changing activity name breaks link with ClearQuest
record
When
a ClearCase activity in a project enabled for ClearQuest is linked to a ClearQuest
record, the Name of
the ClearCase activity is set to match the ClearQuest record’s ID. This
allows you to access the corresponding activity when you are working on a
defect by using the current defect number. For example, you can use the command cleartool setactivity ClearQuest-record-ID We
recommend that you do not change the name of a ClearCase activity, although
ClearCase does not prevent that. If you change an activity name, you cannot
use the setactivity command
as illustrated above. Note that the Headline field for a ClearCase activity is
synchronized with the corresponding field in a ClearQuest record. That is,
if you change this field from within either ClearCase or ClearQuest, the corresponding
field in the ClearQuest record or ClearCase activity is modified as well. #CMBU00028501
(#31944) snapshot view limitation on VOB symbolic links
VOB
symbolic links are limited to one level of indirection in snapshot views.
That is, the result of cleartool ln –s is loaded as a native file-system symbolic
link only if the source is not another VOB symbolic link. #CMBU00029594 (#33174) integration stream property sheets may not show
delivered activities
In the Project Explorer, the Activities tab
of the baseline and integration stream property sheets does not list the activities
that have been delivered to the integration stream and incorporated into the
baseline. The Activities tab displays only activities that were created
in the integration stream, including integration activities, which ClearCase
generates during deliver operations. #CMBU00030700,#CMBU00032384
(#36267) Print to File option does not work
The Print
to file option of applications
such as Microsoft Word does not work for an MVFS file. Attempting to print
to file within the MVFS may result in the error access denied or
the application may appear to hang as it continues to try to write the file.
The problem is that the mechanism used for this function uses an identity
that does not have the proper credentials for the MVFS to be able to validate
it. The workaround is to print the file to a file outside the MVFS (such as
a local or network drive) and then copy it into the MVFS from there. #CMBU00031042 (#34757) GUI does not display Version Tree after checkin
of hijacked file
If you use the Update window (opened
by clearviewupdate)
to check in a hijacked file element, and then try to use the GUI to display
a version tree of that element, the version tree is not displayed. Instead,
the tool displays the following error message: xclearcase: Error: Invalid pathnames
The
error message is displayed on the command line in the terminal window where
you started clearviewupdate. Workaround: Use the command line interface tool xlsvtree to
display the version tree. #CMBU00031043
(#34758) on Linux and Solaris Intel systems, selecting hijacked folder produces
empty Name field
On Linux and Solaris Intel platforms,
if you use the Clear View Update GUI to check in a hijacked file element,
and then use the GUI to select the hijacked folder, the tool displays an empty Name field,
instead of listing the name of the hijacked file that was checked in. #CMBU00031647 (#35432) config spec may not be synchronized before update
preview
In
a UNIX snapshot view, your config spec may not be correctly synchronized before
all update previews. However, synchronization is always correct for full updates. #CMBU00033367
(#37371) delivery of selected activity does not detect directory dependency
across activities
If you create a new element in one
activity (for example, A) while the directory containing the element is checked
out to a different activity (for example, B), you have created an implicit
dependency of A on B. When selectively delivering activity A, you must also
include activity B. Otherwise deliver reports the error: DBID not found. #CMBU00033579
(#37602) Project Explorer Transcript window does not always respond
The
Transcript window may open when exception conditions have occurred during
an operation. When the Transcript window and another modal dialog box are
open, such as a properties dialog in which operations can be initiated, the
Transcript window does not respond to user actions. You must close the dialog
box before you can adjust the scroll bar of the Transcript window to view
the full message or event log. #CMBU00034173 (#38270) relocate
does not preserve lock applied to branches
If a branch of an element is locked,
rather than the element itself, you can relocate the element along with the
branch. However, the relocated branch is no longer locked. #CMBU00034704
(#38851) symbolic links to hijacked files show up as duplicates in list
Symbolic
links to a hijacked file appear in the clearviewupdate hijacked file list along with the
file itself. As a result, multiple entries in the hijacked list refer to the
same file. #CMBU00034794
(#38950) update –add command in snapshot view may fail if working directory
is global network path
When you are working in a snapshot
view whose working directory is a global network path (for example, of the
form /net/hostname/directory),
the update –add command
may fail with the message: cleartool: Error: Unable to determine version for VOB root directory element.
Workaround: Specify your working directory using
the local absolute path, for example, /usr1/smith/views/4.0_view. #CMBU00035331 canceling a uncheckout
confirm window hangs ClearCase-FrameMaker integration
There
is a known error that occurs when you close an Uncheckout confirmation dialog
box. It causes Adobe FrameMaker to hang. #CMBU00040782 (#39625) on Red
Hat Linux, Describe command displays error message when multiple files are
selected
On
Red Hat Linux, if you select multiple files before you click Report > Describe in
the File Browser, the Describe window displays an error message: Workaround: The Describe window displays the correct
information when you select one file. #CMBU00040953 (#39803) HTML generation
code uses local paths even when inappropriate
When a file in an xcleardiff pane is rendered to a HTML browser,
the HTML browser may not be able to display the file if the browser is running
on a different host than xcleardiff. This situation occurs when xcleardiff does
not generate a pathname to the file that is accessible from the host on which
the Web browser is running. Workaround: Run xcleardiff on the machine where the HTML browser
is running. #CMBU00041571
describe -graphical cannot handle white space in path name
Attempting
to describe files whose names have shell special characters (for example, *) or spaces
from the graphical interface may fail with a file
not found error. For
example, the following describe command fails because it treats the file name
as two separate names: cleartool
describe –graphical “my file“ #CMBU00042778
cleartool commands use one date format
The output of most cleartool commands that display date information
uses an invariant format that ignores regional standards. #CMBU00043178
using Web interface with Netscape causes error messages
Clients
using Netscape Navigator may cause error message similar to the following
to appear in the web server logs:
File does not exist: /usr/atria/web/applets/com/ms/security/PermissionID.class
File does not exist: /usr/atria/web/applets/com/ms/security/PolicyEngine.class
These
error messages are harmless and can be ignored.
#CMBU00043725
change in behavior of rgy_backup causes no backup to be done and no errors
rgy_backup does not copy a new rgy_hosts.conf file to any client running the command.
To configure a new registry backup server, the rgy_hosts.conf file on the new backup host must be
edited to add the backup host name. Any subsequent runs of rgy_backup on that host cause a registry backup
to occur. #CMBU00044762
ClearCase/DDTS Integration on Linux Needs Environment Variable Defined
If
you want to use ClearCase on a Linux client, you must set the environment
variable BUGTRACK_RSH_COMMAND for the integration to work successfully with
a remote DDTS server. #CMBU00048303 lsclients command no longer shows if release is patched
Patch
information for ClearCase releases may not be correctly displayed by cleartool lsclients. Workaround: Use cleartool –ver . #CMBU00051601
Anomalous behavior when more than one user uses same snapshot view from same
user account
Anomalous
behavior can result when more than one user uses the same snapshot view from
the same user account. This usage pattern is neither recommended nor supported
for snapshot views, and the results are not guaranteed. #
CMBU00052228 Problem with mounting a non-ClearCase related filesystem from
within a view on Linux
Problem: If you mount a non-ClearCase
file system, such as cdrom, ext2, etc., from within a view, that now-mounted
file system is not visible from outside that view. For example, if you mount
the cdrom while inside a view the cdrom contents are visible from only that
view. This
occurs on Red Hat 6.2 Linux and Red Hat 7.0 Linux systems. Explanation:
The observed behavior is a result of a difference between Linux and Unix.
Linux does all of its lookups through a cache of directory names. Inodes
are accessed from these directory entries. This means that file accesses
are tied to your directory name space. When you are set to a view, you have
effectively changed the root of your process to /view/<viewtag>. This then is linked to the real system
root. However, even though it isn’t visible to you, your namespace still
has the /view/<viewtag> prepended to it. Therefore, when you
are set to a view and you mount /dev/cdrom onto /cdrom, for example, you have actually mounted
the device on /view/<viewtag>/cdrom. The
MVFS maintains a shadow file system under the view namespace that redirects
file references, when possible, to the actual underlying file. However, the
mount code directly calls into the MVFS only if it is mounting an MVFS filesystem.
There is no way of trapping and redirecting the mount request since the mount
itself is handled by the cdrom’s filesystem. If the cdrom is mounted
outside of a view, it is also visible inside the view. However, if the cdrom
is mounted from within the view, it is visible only by using the full view-extended
pathname to the mount point. #CMBU00052325
ClearCase Integration with Forte for Java not available on Linux
The
Rational ClearCase integration with Forte for Java is not available for Red
Hat 6.2 Linux and Red Hat 7.0 Linux. This is because of a defect in Sun’s
Java Virtual Machine implementation that interferes with command line processing. #CMBU00055513
Netscape doesn’t list integration stream when creating a UCM project
view
When creating a UCM integration view, the stream
it will be attached to, and any existing web views for that stream, are displayed
in Internet Explorer, but not in Netscape Navigator, due to limitations of
the support for dynamic HTML in Navigator 4.x.
#CMBU00056755 limitations on
deliver/rebase status display when using Netscape Navigator
On
Internet Explorer and above, deliver and rebase status is indicated by incremental
updates to the status text area, the transcript, and the file listing area,
as data is received from the server. Because of bugs in Netscape Navigator
4 which causes the browser to crash when partially occluded, the file listing
area cannot be updated incrementally (that is, changes to checkout and merge
state cannot be updated incrementally). When using the ClearCase Web interface
through Netscape Navigator 4, the file listing area is updated after each
major phase of the deliver/rebase request has completed.
#CMBU00056810 UCM pre-defined
queries are broken when upgrading to package UCM3.0 or UCM4.0
The
UnifiedChangeManagement package has six pre-defined public queries,
-- UCMUserQueries\UCMProjects -- UCMUserQueries\MyToDoList -- UCMUserQueries\ActiveForUser -- UCMUserQueries\ActiveForProject -- UCMUserQueries\ActiveForStream -- UCMSystemQueries\UCMCustomQuery1 Two
of the above queries are used by UCM/ClearQuest integration, UCMCustomQuery1
and MyToDoList.
In UCM1.0 and UCM2.0 Package, query
MyToDoList is defined as:
AND
ucm_statetype in (’Active’, ’Ready’)
Owner = ’(CURRENT_USER)’Upgrading to the UCM3.0 package requires
the AMStateType 1.0 package; after applying the AMStateType 1.0 package,
the field ucm_statetype no longer exists (using am_statetype instead). But since the pre-defined
queries in UCM 3.0 do not reflect this change, they do not perform the expected
functions. This problem is corrected in the UCM 4.0 package
shipped with ClearQuest Version 2002.05.00. To correct the problem in UCM
3.0, replace occurences of ucm_statetype with am_statetype where they appear, using the same
values that were associated with the previous field name. For example, the
MyToDoList query should be defined as AND
am_statetype in (’Active’, ’Ready’)
Owner = ’(CURRENT_USER)’#CMBU00056997 Netscape browser
crashes if window is resized
When running the Web interface from
a Netscape browser, avoid resizing the browser window during operation; this
can cause Netscape to crash.
#CMBU00057114 interoperability
issues running UNIX Web server and Windows ClearCase Web client
When
entering a version identifier as an Advanced version-selector in the Welcome to Merge Manager page,
you must use forward slashes (/) if the Web server is running on UNIX. If
the Web server is running on Windows, you may use either forward (/) or backward
(\) slashes.)
#CMBU00057168
occasional problems using ’Back’ button on Netscape 4
When
using the ClearCase Web interface on a Netscape 4 browser, use of the browser’s Back button
can cause unintended results in the Web user interface.
#CMBU00057289 xclearcase must
be run from within a snapshot view
When working in ClearCase LT on UNIX,
start xclearcase from
within a snapshot view to avoid any problems with the menu bar commands that
require a view context. If you try to start xclearcase when not in a snapshot view, the program
displays an error message saying that macro expansion failed.
#CMBU000
57847 Install scripts may abort when an obsolete German locale is specified
added
at 5.0 NR
Some German locales are obsolete, such as De, De_DE.646,
De_DE.646@EU, and De_DE.646@TE. If the current locale is set to one of these
obsolete versions, the install scripts may abort with a syntax error. If
this occurs, you must select and set a new locale before rerunning the installation.
#CMBU000
57983 Javascript error when navigating to certain directories with symlinks
In
the ClearCase Web interface, when you browse to a directory that contains
a symbolic link with a backslash (’\’) in its link text, a Javascript
error is displayed.
Workaround: Change symbolic links to use forward
slashes instead. (Forward slashes work with both Windows and UNIX clients.)
