Product Readmes


Abstract

New features and other changes in ClearCase®.

Content

V8.0.1.7

Automatic views

The automatic view is a new type of view that combines features of the dynamic view, such as instant workspace creation and shared cleartext caches, with features of the web view, such as WAN friendliness and support for working offline. For more information, refer to http://www.ibm.com/support/pages/node/257649.

Enabling SSL V3

A new environment variable and config.pl parameter can be set to enable SSL V3, which is disabled by default due to its vulnerability to POODLE attacks; refer to http://www.ibm.com/support/pages/node/525397.

CMI-JIRA integration

CMI (change management interface) supports the JIRA task provider; for instructions on configuring CMI for JIRA, refer to http://www.ibm.com/support/pages/node/526941.

Displaying UCM baseline overrides

The capability of displaying baseline overrides has been enhanced in this release to support formatted output. For more information, refer to http://www.ibm.com/support/pages/node/256137.

Dealing with unwanted UCM baseline dependencies

The script findUnwantedDependency.pl finds unwanted baseline dependencies and prints commands for removing them. For instructions on using the script, refer to http://www.ibm.com/support/pages/node/527339.

Changes in CTE snapshot view support

CTE snapshot view support has been extended to include the following features:

  • Multisite
  • RTC integration
  • Logical resources
  • UCM-CQ integration
  • Visual Studio integration

CTE support for load rule commenting in config specs

CTE now supports load rule comments in config specs for web and snapshot views. (NOTE: automatic views and rcleartool do not support load rule commenting in this release.)

Enhancements to the Cadence Virtuoso integration

The following enhancements are delivered in this release:

  • SRFM support: support for synchronous request for mastership (SRFM) has been extended to "delete" operations from the Library Manager or Work Area Manager (WAM). (SRFM support was previously limited to "create"and "checkout" operations.)
  • Handling of duplicate names: when an error is encountered during check-in of unmanaged designs, an attempt is made to restore these elements to their original names. Sometimes the restoration can fail due to an eclipsed element. In that case, the restoration process renames the unmanaged designs by appending _mkelem to the original names.
  • Support for Red Hat Enterprise Linux 6.6.

Changes to the command line

There are no changes to any ClearCase® commands in this release.

Status of the feature level

The ClearCase® VOB feature level is unchanged in this release. For information on feature levels and ClearCase® releases, refer to http://www.ibm.com/support/pages/node/73065.

Enhancements to the Cadence Virtuoso integration

This release introduces the following enhancements to the integration with Cadence Virtuoso:

  • The ClearCase® "Label parents" feature has been enhanced to allow labeling of parent directories up to and including the VOB-tag directory of the library. The "Label files" feature labels all files in all labeled parents. Accordingly, the label report has been updated to list the files that were labeled in the parent directories.
  • Using the Work Area Manager (WAM) context menu, you can convert a reserved checkout in a view other than the current one to an unreserved checkout.

Snapshot view performance improvements

In a ClearTeam Explorer snapshot view, the performance of operations such as deliver, rebase, merge, and add-to-source has been improved significantly.

For information about changes to automatic view support, refer to http://www.ibm.com/support/pages/node/257649.

Change Management Interface (CMI)

This release introduces the following changes to CMI:

  • Optional stored credentials: it is no longer necessary to use the cmiregister command to store credentials for ClearTeam Explorer (CTE) users of the ClearCase® Local Client (CCLC). As with CTE users of the remote client (CCRC), CTE-CCLC users are prompted for credentials if valid credentials have not been stored.
  • Custom ClearQuest® fields: for instructions on customizing ClearQuest® record fields, refer to http://www.ibm.com/support/pages/node/272727.

NOTE: For a comparison of the capabilities and limitations of the ClearCase® UCM integrations with ClearQuest®, including CMI, refer to http://www.ibm.com/support/pages/node/529361.

Visual Studio support

This release introduces support for Visual Studio 2015

Enhancements to the Cadence Virtuoso integration

This release introduces the following features:

  • ClearCase® Delete: this operation irrevocably destroys a ClearCase® element (it corresponds to the cleartool rmelem command).
  • CCASE_CDS_CANCEL_WITH_KEEP: when set to TRUE, gdmcancel operations create .keep files by default.

ClearTeam Explorer (CTE) enhancements

Support for the following features has been added to CTE:

  • Update logs for snapshot views (Default log file name: update.timestamp.updt)
  • Importing a VOB or specified VOB directory as a UCM component

Problems and workarounds

Changes to the command line

There are no changes to ClearCase® commands in this release.

Status of the feature level

The ClearCase® VOB feature level is unchanged in this release. For information on feature levels and ClearCase® releases, refer to http://www.ibm.com/support/pages/node/73065.

V8.0.1.11 through 8.0.1.12

ClearTeam Explorer (CTE) enhancements

Checking out and merging arbitrary versions by using the version tree

In this release, you can check out any version of an element from its version tree. (In older releases, the only candidate for a checkout operation was the version selected by your view.) Similarly, you can select any version in the tree as the merge-to version.

Send-to menu item (Windows only)

When you right-click a version that is displayed in the version tree, the history browser, or the change set viewer, the context menu includes a "Send to" menu item that you can use to send a copy of the version to an email recipient, create a shortcut on your desktop, and so on.

Cadence Virtuoso integration enhancements

Locking label types

The integration supports locking a label type, which prevents instances of the type from being moved.

Opening cellviews in read-only or edit modes

The Hierarchy Manager and Work Area Manager (WAM) support opening a cellview in either read-only or edit modes. Right-click on the cellview and select "Open read-only..."or"Open for edit...".

Filtering label types

You can filter label types to include only the types that you want to see. Type the filter text in the "Label Filter" text box, then click "Fetch labels." You can also set the environment variable CCASE_LABEL_FILTER to a filter value, which causes the "Label filter" box to be populated with that value.

Improvements to rename operation

The rename operation supports synchronous requests for mastership (SRFM) and polling for checkout and checkin of nonmastered parents in replicated VOBs. A library rename update references automatically (previously, references had to be updated manually). Note that you cannot rename an object if the cell view is open in an editor.

Listing hierarchy elements managed by ClearCase®

Use the option "Show Items With DM System CCASE" to filter out cell views in a design hierarchy whose design manager is not ClearCase®.

Platform support

This release of the integration supports Cadence Virtuoso IC617 and Red Hat Enterprise Linux 7.

Platform support

ClearCase® supports the following platforms in this release:

V8.0.1.23

Security

Crypt::SSLeay v0.72 has been removed from the product due to incompatibility with OpenSSL 1.1.1d.

If you use ratlperl, ccperl, cqperl, SSL/TLS connections, LWP::UserAgent, and Crypt::SSLeay in your own perl scripts, you are affected by this change.

The suggested fix is to stop importing the Crypt::SSLeay SSL implementation module in your perl scripts and letting LWP::Protocol::https default (or explicitly use) to the provided IO::Socket::SSL module.

About upgraded Net::SSLeay to version 1.88, for change history and usage, see http://metacpan.org/release/CHRISN/Net-SSLeay-1.88.

About upgraded IO::Socket::SSL to version 2.066, for change history and usage, see http://metacpan.org/release/SULLR/IO-Socket-SSL-2.066.

You are affected by these changes if you use ratlperl, ccperl, cqperl, and use either Net::SSLeay or IO::Socket::SSL. See the corresponding module documentation for interface changes.
