Note: This technology comes in three editions: Community, Business and Enterprise. This technology allows users to install, remove, upgrade, and manage these Tcl modules on their production environments. More information on the proper use of the TRM can be found on theĪctiveTcl is a development framework that houses Tool Command Language (TCL) modules. If you have any questions regarding your TDK/Pro Studio deployment, wrapping technology, or other technical questions, please contact technical support.Technologies must be operated and maintained in accordance with Federal and Department security and If you have any questions concerning the pending EOL, or the impact to your organization around licensing issues, please reach out to the salesperson for your account, or else contact Sales. ActiveTcl nodes are included as part of the Team, Business and Enterprise Tier ActiveState Platform subscriptions.If an ActiveTcl distribution was used to wrap files for internally deployed applications, every system where that application is installed will require an additional ActiveTcl node license.OEM agreements are available to customers with an ActiveState Platform Enterprise Tier subscription.If an ActiveTcl distribution was used to wrap files for an external customer, an OEM agreement will be required.Grandfathering will end on October 1, 2020. In effect, TDK/Pro Studio customers have been grandfathered for the past 4 years. The resulting modified license was posted to the ActiveState website and counts as an update to your existing license terms. However, when ActiveState discontinued TDK/Pro Studio in 2016, this clause was removed from the ATCE license. Previously, the ATCE/ATBE license allowed TDK users to build and deploy, or even redistribute files without needing to attach a more senior license to the wrapped file. The majority of TDK owners use it in conjunction with ActiveTcl Community Edition (ATCE). If ease of deployment is required, hosted services, VMs, or containers are far more future-proof.If obfuscation is required, the program should be converted to a compiled language, or converted to a hosted service that can’t be tampered with.Instead, ActiveState recommends that Tcl scripts should be shipped in unwrapped form with the following caveats: Ultimately, wrapped bytecode is insecure, and should not be used to protect intellectual property, or sensitive data such as login credentials. If done carefully, the change can be difficult to detect. These two tools allow a wrapped file to be opened, de-obfuscated, modified, and re-wrapped. In fact, a tool to explore the contents of a Tcl virtual filesystem has been freely available since the release of ActiveTcl 8.5. However, customers should be aware that open source, third party tools to crack Tcl bytecode have been freely available for several years. No new licenses are available for purchase.ĪctiveState acknowledges that many TDK customers purchased it in order to deploy wrapped Tcl code. Existing TDK licenses should not be reassigned.This includes updating or adding any new Tcl modules. Neither TDK nor your deployment of ActiveTcl should be upgraded.Existing deployments should not be moved to new hardware, or a newer version of the operating system, which are more likely than not to be incompatible with TDK.In the meantime, be aware of the following potential issues with existing deployments: While EOL will not occur until October 2020, the best course of action for customers is to end their reliance on TDK and remove it from their enterprise. As a result, we are advising TDK/Pro Studio users to end their use of the product and its tooling, and either deploy their programs unobfuscated, or convert them to a compiled language. Support for existing contracts will cease on October 1, 2020. TclDebugger – used for profiling Tcl codeĪctiveState no longer builds or maintains any of the tools that ship with TDK, and will stop renewing support subscriptions immediately.TclApp – used to create stand-alone executables.That includes all of the following tooling: However, sales of TDK/Pro Studio were discontinued in 2016, and End of Life (EOL) is now pending. ActiveState’s Tcl Dev Kit (TDK) and ActiveTcl Pro Studio have been providing the Tcl community with essential tools for building and deploying Tcl applications for decades.
