Announcing Synergy/DE 11.1.1h

By Steve Ives, Posted on July 19, 2021 at 9:49 am

Steve Ives

Synergex is pleased to announce the immediate availability of Synergy/DE 11.1.1h on all platforms. A quality release that includes a wide range of improvements across the entire Synergy product line, and we strongly encourage all Synergy developers to review the release notes for detailed information about everything that changed.

If you are one of the many developers using Synergy DBL Integration for Visual Studio (SDI), please note that this will be the final release that supports Visual Studio 2017. From the next release, SDI will support Visual Studio 2019 as well as the upcoming Visual Studio 2022.

As we continually enhance the isutl utility for improved performance and better recoverability in system crash scenarios, we recommend that all customers using Synergy DBMS download the latest version of the Synergy DBMS Utilities package, regardless of the version of Synergy that you are currently using.

And finally, we want to point out an important bug fix that we applied to xfServer in this release: “On Windows and UNIX/Linux, a pre-version 11.1.1 client connecting to an 11.1.1 through 11.1.1g encrypted xfServer caused the connection to hang on certain functions, such as ISSTS, CLEAR, and STORE. This has been fixed in this release.”

Synergy/DE 11.1.1h is available for download in the Resource Center now.


CodeGen 5.7.3 Released

By Steve Ives, Posted on July 9, 2021 at 6:47 pm

Steve Ives

There’s a new version of CodeGen out there, so if you’re using it, here’s what’s changed in this version:

  • We added a new special structure expression token <STRUCTURE_HAS_FIELD_name> that allows you to detect the presence or absence of a named field within the structure.
  • We improved the logic used when processing unique key loops and unique alternate key loops and made a slight change to the way that the unique alternate key loops operate. Previously the loop would not compare alternate key segments with the primary key, but now it does. So the loop now processes any alternate keys that do not have identical key segments to the primary key or any previous alternate keys.
  • We fixed a problem with the implementation of the -pa command line option that would cause CodeGen to fail when used with an input file containing multiple structures.
  • We fixed a problem with the implementation of the -tweaks option which could result in a null reference exception in some rare circumstances.
  • We reviewed and updated all sample templates that ship with CodeGen to ensure they use the latest capabilities such as taking advantage of complex expressions to simplify template complexity resulting from nested expressions.
  • This version of CodeGen was built with Synergy/DE 11.1.1g and requires a minimum of version 10.1.1 to operate.

As always, this new release is backward compatible with earlier releases, so we recommend that everyone download the new version as soon as possible.


Updated Visual Studio Development Tools Update

By Steve Ives, Posted on March 29, 2021 at 10:44 am

Steve Ives

Synergex is pleased to announce the immediate availability of a new release of the Synergy DBL Integration for Visual Studio, Version 11.1.1g-3045.

As always, this latest release contains improvements across the board, but in particular, the focus was placed on these specific areas:

  • Improving the development experience in both the editing and debugging of .NET Core code.
  • Improvements in working with Repository projects in various scenarios.

Some of the improvements in this release were actually in the Synergy .NET Compiler, so in addition to updating the SDI installation, developers working on .NET Core projects (including any Harmony Core projects) should upgrade the version of the Synergex.SynergyDE.Build NuGet package used in the projects to version 11.1.1070.3045 also.

We encourage everyone undertaking any type of Synergy development in Visual Studio to upgrade to this new release as soon as possible. And remember, if you are not ready to upgrade the runtime versions on your production systems yet, you can use runtime version targeting to give you access to the latest-and-greatest development tools while continuing to support older runtime installations.

Head on over to the Resource Center Downloads page to download the new release now.


CodeGen 5.6.9 Released

By Steve Ives, Posted on March 11, 2021 at 8:10 pm

Steve Ives

We are pleased to announce another release of CodeGen, once again including some significant advances in the technology. We recommend that all developers using CodeGen, and especially developers working with Harmony Core, should upgrade to this latest version as soon as possible. This new version includes these changes and enhancements:


Announcing Synergy/DE 11.1.1g

By Steve Ives, Posted on February 26, 2021 at 3:33 pm

Steve Ives

Synergex is pleased to announce the immediate availability of Synergy/DE 11.1.1g, a quality release that includes a wide range of improvements across the entire Synergy product line. We strongly encourage all Synergy developers to review the release notes for detailed information about everything that changed.

Besides a significant focus on quality, we have also made several feature enhancements in our Visual Studio integration tools, enhancing the developers’ experience and improving their productivity.

First off, we have introduced collapsible-region support for many DBL statements and other language constructs. For example, some of the now collapsible statements include BEGIN-END blocks, USING-ENDUSING, CASE-ENDCASE, IF-THEN-ELSE statements, and more. This feature was specifically requested and voted on by developers in the Synergy Ideas Forum.

We also added support for activating the go-to-definition feature via mouse clicks, in addition to using the existing keyboard shortcut-based mechanism. The default behavior is activated via Ctrl + Left-Click but is customizable in the Tools/Options dialog under Text Editor settings.

Another area that we focused on is improving the accuracy of those “red squiggles” that show up in your code when something is wrong and occasionally when something is not wrong! Inaccurate red squigglies should occur less frequently now, although we do know that have some additional work still to do in this area.

To give developers more options when they need to get in quickly and look at something specific, especially in solutions with large numbers of projects, we also implemented support for Visual Studio 2019’s “Filtered Solution” feature that allows you to check a “Do not load projects” option in the Project Open dialog. Visual Studio opens the solution very quickly when you do this, but all projects are in an unloaded state. The developer can then select the projects they wish to work on in Solution Explorer and use the “Reload Project” context menu to load them. The context menu then includes options to allow you to load either direct dependencies or all dependencies of the projects you loaded, meaning that you can quickly get to a buildable scenario without having all projects loaded. Solution Explorer also has options to show or hide unloaded projects.

Having filtered your solution the way you want it, you can then use the “Save as Solution Filter” context menu to save the state of your solution for the next time you need it that way. The file is saved as a .slnf file and can be reopened the same way you open the solution.

We have overhauled our project build system, reduced memory usage, and improved performance for Visual Studio and command-line builds. And at the same time, we have improved and standardized the way they interact with MSBuild, allowing us to adopt new features more quickly.

And armed with our new MSBuild capabilities, we added support for a new feature known as /graphBuild, making pre-build analysis of inter-project dependencies work much more effectively. In turn, MSBuild can now more effectively perform parallel builds of multiple projects simultaneously, in some situations resulting in improvements in overall build time.

We are confident that most developers should experience improvements in overall build times across the board, particularly for traditional Synergy projects. And in some cases, with the right combination of projects and resources, those improvements could be significant.

For example, suppose you have a small number of base libraries used by a large number of higher-level projects. In that case, once those base libraries have been built, there is a good chance that higher-level projects can build in parallel, with the overall process completing more quickly. The more CPU and memory resources that are available, the faster things can proceed. In some environments, such as on dedicated build servers running CICD pipelines, we have seen improvements of up to 30 – 40% in overall build time as compared to the previously released version. But improvements of that order do require access to considerable resources; most improvements will be more modest.

If you’re already using Visual Studio to develop your Synergy code, we encourage you to upgrade to this new version as soon as possible; remember, you can always use runtime version targeting if you’re not ready to upgrade your production systems. And don’t let the fact that you only develop traditional Synergy code or deploy to Unix, Linux, or OpenVMS deter you; Visual Studio can make a great development environment for those scenarios too! Talk to your Synergex account representative for more information.


CodeGen 5.6.6 Released

By Steve Ives, Posted on February 5, 2021 at 3:05 pm

Steve Ives

A quick post to announce the availability of CodeGen 5.6.6.  This is a quality release that addresses an issue that could occur when generating code from templates containing certain complex expressions. In particular, several Harmony Core templates contain such complex expressions, so we recommend that all Harmony Core developers upgrade to this new version of CodeGen at their earliest convenience. As always, documentation for this new release can be found at https://codegen.synergex.com.


CodeGen 5.6.5 Released

By Steve Ives, Posted on January 24, 2021 at 11:13 pm

Steve Ives

I am pleased to announce the release of a new version of CodeGen, and this release is quite a big one. The changes include the following:

This version of CodeGen was built with Synergy/DE 11.1.1f and requires a minimum of version 10.1.1 to operate.

We recommend that all CodeGen users upgrade to this version, particularly if you are doing Harmony Core development. You can download the new version from GitHub.


SQL Replication Enhancements

By Steve Ives, Posted on December 4, 2020 at 3:21 pm

Steve Ives

For several years now, Synergex has maintained an open-source example that provides an example of how to implement the replication of a Synergy applications data to a Microsoft SQL Server database, in near-to-real-time. The example environment makes considerable use of CodeGen to generate the bulk of the code needed to implement the interaction with the SQL Server database, and much of the remaining required code can be used out-of-the-box, requiring very little, if any change to the original Synergy application to enable the data replication to take place. The example environment has been used as a template by many customers, and our Professional Services team has assisted many others by delivering either proof of concept examples, or full-scale implementations.

As technologies and product capabilities evolve, we periodically revisit the code to ensure that it is taking advantage of the latest features and adhering to best practices. Good performance is also of critical importance in products like this, so we frequently revisit the code looking for opportunities to make improvements in throughput.

We have just completed the latest review of the code, and on this occasion, we did make some changes, which are briefly described below.

  • We now generate an additional function that returns the key number of the first unique key for each ISAM structure. This allows us to avoid the need for code that previously detected the first unique key number at runtime; that code required that the replicator had an open channel to each data file being replicated.
  • We also generate an additional function that, when passed a record containing data, returns the key value of the first unique key. Previously, the code used the Synergy routine %KEYVAL for this purpose, but it also requires that the replicator has an open channel to every data file replicated.
  • Because of the previous two changes, we were able to remove the replicator’s requirement to open the underlying data files that are being replicated. The only files that the replicator now opens are the instruction queue file and log file.
  • We added code to make the replicator more resilient to interruptions to network connections when using xfServer to access the instruction queue file on a remote system. If a network problem is detected, the replicator now closes the instruction queue file and then attempts to re-open it on a new channel. If this operation fails, it will retry several times with a delay between attempts. The number of retries and the delay between retries are both configurable via command-line options or environment variables.

If you already have a SQL Replication environment based on our sample environment, then you might consider checking out the latest version and applying the changes to your own codebase, and if you’d like some help with that, then our Professional Services team will be happy to assist. And if you haven’t yet implemented a SQL Replication environment but are interested in doing so, get in touch with your Synergex account rep and ask them to set up a demo.


Announcing Synergy/DE 11.1.1f

By Steve Ives, Posted on September 22, 2020 at 2:11 pm

Steve Ives

We are pleased to announce the release of Synergy/DE 11.1.1f. This is a quality improvement release available immediately on all Synergy-supported platforms. Please refer to the release notes f0r important information on issues addressed by this release.

Amongst other things, this release addresses several issues relating to running xfServer with encryption enabled. This is a configuration that we highly recommend for all xfServer deployments. If you are doing so and are running an earlier version of Synergy 11, we encourage you to upgrade your server and client systems to 11.1.1f.


Improving Our Internal Development Process

By Steve Ives, Posted on September 21, 2020 at 11:21 am

Steve Ives

We’re about to release another version of Synergy, and when we do you may notice that we’re not documenting any new features in the release. This is an intentional change, and I wanted to let you know about it ahead of time.

In addition to working on Synergy/DE, our development teams are also working on re-organizing many of our internal systems, tools, and practices. We’re centralizing almost all of our development around Microsoft Azure DevOps; we’re consolidating all version control on Git (currently, depending on the product area and platform, we also use PVCS and Subversion), we’re making extensive use of CICD principles and tools to build automated build and test pipelines for all aspects of the product, and much more.

The only exceptions to this are our open source products, CodeGen and Harmony Core, which will remain in their current locations on GitHub. This will be an on-going process extending well into 2021 and, when complete, will put us in a great position to be able to return our focus entirely to Synergy/DE within a modern, highly efficient and productive development environment.

And as part of this reorganization of our environment, tools and practices, we have also made some decisions about how we’re going to release changes to the Synergy/DE products. For the core Synergy/DE runtime products, we have decided to revert to our earlier practice of only releasing quality improvements in patch releases; new features will be released less frequently, in numbered product releases. There are some other changes coming down the pipeline, but we’re still fleshing out some of the details, we’ll let you know as soon as things are firmed up.

This decision applies to the runtime products only, not to the development tools; you will still see regular releases for the Visual Studio-based development tools (and maybe more) in the near future. And development and releases of CodeGen and Harmony Core will continue as normal.


Migration to New Downloads Site Completed

By Steve Ives, Posted on August 14, 2020 at 2:40 pm

Steve Ives

Back in June, I announced the launch of a new product downloads site, which at the time provided access to all of the Synergy 11 downloads, and that downloads for earlier versions would be migrated over the coming months. I am pleased to announce that process is now complete and that the downloads for products all the way back to Synergy 7.1 are now available from the new site and have been removed from the old resource center.

The old download pages also included downloads for the Synergy V6 products but, because the way the software was distributed was so different back then, we decided not to migrate those old versions to the new site. For now, the version 6 files can still be downloaded from the old resource center, and we will make those files available via some alternate mechanism before that site is eventually decommissioned.


Announcing Synergy/DE 11.1.1e

By Steve Ives, Posted on July 14, 2020 at 2:04 pm

Steve Ives

Due to the discovery of a potentially serious issue in the 11.1.1d release of Synergy/DE, we have decided to withdraw that release on Windows and UNIX platforms and replace it with 11.1.1e, which is now available.

To understand the issue, it is first necessary to understand that enabling compression on a data file can, in rare cases, result in a small increase in the size of some records! This can only occur if the data in a record is not compressible, yet the compression itself adds a small overhead.

It was found that when reading records from a compressed file, by RFA, any records exhibiting this “negative compression” would have one byte of bad data returned at the end of the record.

11.1.1e includes new versions of Synergy/DE 32-bit and 64-bit for Windows and Unix platforms, and Synergy DBL Integration for Visual Studio (build #2769).

We strongly recommend that anyone who has updated to Synergy/DE 11.1.1d on the affected platforms should immediately upgrade to 11.1.1e.

As we needed to release a new version to address the READ by RFA issue, we decided to also include several other quality improvements that had already been completed.

Synergy/DE Runtime

(Windows) In 11.1.1d, when using SYN_RESIZE_SCALE or having a monitor DPI change, some .NET controls would fail to repaint if the application moved between monitors of different DPI or scaling.

Traditional Synergy Compiler

A global structure with the same name as a subroutine no longer causes a segmentation fault when loading prototype files when there are different prototype files for the global structure and the subroutine.

Synergy Configuration Program

We addressed an issue in rsynd that was causing the SynConfig utility to fail with a “Could not complete services import” error when specifying a user account during service import.

Synergy DBMS

We enhanced the isutl utility when recovering change tracking files with bad change tracking links, and the utility no longer crashes if certain wildcard file operations are attempted.

Visual Studio Build System

We fixed an issue in the incremental build feature in SDI 11.1.1d-2749 through 11.1.1d-2763 that caused full project builds to occur when only partial builds were necessary for projects using common.props and with non-Synergy references.

We fixed an issue that prevented low-level libraries in Synergy .NET Core solutions from automatically rebuilding when an output file was missing.

Visual Studio Property Pages

We fixed an issue that prevented Visual Studio settings imported from a file from working until a Synergy DBL option page (Tools > Options > Text Editor > Synergy DBL > …) was opened.

We fixed an issue with Synergy .NET Core and .NET Standard projects that prevented SDI from resolving known MSBuild properties used for pre-build and post-build events.

For additional information and tracker numbers associated with each of these items, please refer to the release notes.


Announcing SDI 11.1.1d-2763

By Steve Ives, Posted on July 2, 2020 at 1:01 pm

Steve Ives

Shortly after the recent release of SDI build 2755 we discovered an issue that we wanted to address as soon as possible, so today we are announcing the release of build 2763, which we recommend for everyone using Visual Studio for Synergy development.

We are not aware of any customers being affected by the issue, and we have removed the download link for the previous build.

For additional information please refer to the release notes.


No More SDI “Developer” Builds – Just Releases

By Steve Ives, Posted on June 29, 2020 at 3:12 pm

Steve Ives

I wanted to make you aware of a small change that we have recently made to the way that we refer to “interim” releases of the SDI (Synergy DBL Integration for Visual Studio) product.

A few years ago, it became clear that we needed to be able to release our Visual Studio Integration tools on a more frequent cadence than the main Synergy/DE product. So we started doing interim releases that we referred to as “Developer Builds.” Each developer build was identified both by a version number and a build number.

Initially, these builds were often not subject to the same levels of stringent testing that a build for a full release would be, and we made that clear to customers. But now, thanks to considerable improvements in our automated testing processes, these interim builds are now subject to the same levels of inspection and testing as a build for a full release, and it is no longer necessary to discriminate between developer- and full-builds.

For this reason, we have decided to stop referring to these releases as “Developer Builds,” they are now all just “SDI Releases,” which will continue to occur on a much more frequent cadence than Synergy/DE.
