Synergy/DE - 12.4.1.1003
June 13, 2025

Repository

We added a new "Import type" dropdown to the Load Repository Schema dialog to support the ability to load schema from separate files. This makes it possible to use schema files more effectively with version control change tracking. When "Separate files" is selected as the import type, you must specify the directory from which the files will be loaded. Only files with the .sdl extension will be loaded. 

SQL Connection

We have added the ability to retrieve the return value from a SQL Server stored procedure. See the 12.4 SQL Connection documentation for details.
We fixed an issue that could cause segmentation faults with vtxnetd on Unix.
We fixed an issue that caused the SQL OpenNet service, vtxnetd, to behave unexpectedly (e.g., reporting the error "The system detected an invalid pointer address") when receiving invalid network traffic.

Synergy Language

We fixed a problem that could cause autotime keys to be out of order.

UI Toolkit

We restored behavior in .NET Framework UI Toolkit apps to treat "MSWINDOWS" as the default TERM value if TERM and DTKTERM aren't set.

xfNetLink .NET

We resolved a failure that was occurring during a request to launch an xfServerPlus session from an xfNetLink .NET 8 client that used hostname to connect.

xfServer

We fixed a problem that could cause autotime keys to be out of order.
SDI - 2025.06.1647
June 5, 2025

Visual Studio Integration

We added support for referencing multiple repository projects from a single traditional Synergy or Synergy .NET project. To support this, repository project references include two new properties: "Default Repository". When the "Default Repository" property is set to true for a repository project reference, the referenced repository is used as the primary repository for build and IntelliSense. This property can be set to true for only one repository reference for a project. Changing this to true for a reference causes this property for other repository project references in the project to be set to false.
SDI no longer runs PEVerify for .NET 6+ Synergy projects. Additionally, the "Run peverify on output assemblies" option is no longer available on the Build page of project properties for .NET 6+ Synergy projects.
Completion IntelliSense sessions now include an entry that displays the current user input as a possible completion item. This item behaves the same as any other completion item, and it's automatically suggested when the input doesn't match any of the options generally provided in the completion session. This change makes it easier to declare a new record variable by providing a completion alternative that doesn't overwrite a new variable name you have just typed with another option provided by IntelliSense.
We fixed an issue that caused the warning "The .NET Desktop Development workload isn't installed" to appear when this workload was installed on a system with both the current and preview versions of Visual Studio. This occurred the first time a project was created or opened with the current version of Visual Studio.
We fixed an issue that caused project property pages to be marked as changed ("dirty") when the Build page of project properties was opened for a Synergy .NET 6 or higher project or a Synergy .NET Standard project.
Opening multiple mainline files simultaneously no longer causes IntelliSense background compiles to hang and never complete.
We fixed an issue that caused Visual Studio to crash under certain circumstances when starting a debugging session.
We fixed a regression that reintroduced a previously resolved issue (tracker 38456), where no error dialog appeared when a debug session was started when the working directory was missing.
Specifying options on the Compile page of project properties for a traditional Synergy project no longer adversely affects IntelliSense. Previously, options specified in this field caused errors in  background compiles needed for IntelliSense support.
We fixed an issue that caused dotnet publish to fail with a build error when attempting to publish a Synergy .NET multiple mainline project with a Linux target.
Selecting "Start Debugging" or "Start Without Debugging" for a specific mainline in a multiple mainline project (via the right-click context menu for the mainline) now builds the project if the mainline has changes. Previously, the project would not be built in this scenario. You would have to explicitly build it before starting, or work around this issue by setting the mainline project as the startup project, setting the mainline file as the startup object, and selecting "Start Debugging" or "Start Without Debugging" from the main Visual Studio menu.

We fixed IntelliSense colorization inconsistencies that occurred when pasting code snippets. This also resolves tracker 159518.
We fixed the .NET compiler's prototype generator (-symout) so that it correctly puts out a parameter whose type is an array of type arguments, preventing an unexpected TOKUDF error when that prototype is loaded.
Certain workflows that trigger project reloads, such as rapidly opening and closing  solutions or switching Git branches, can cause SDI to attempt to dispose of components managing background compiles and IntelliSense systems while these operations are still executing. We added handling to prevent exceptions from being displayed to users in these scenarios.
The compiler no longer reports an unexpected IMPTYPARG on a generic method call whose type argument is not specified when passing an array into a parameter whose type is a type argument.
Using Go To Definition on a repository .INCLUDE statement that does not include the type_spec argument (which specifies the type of data structure to create) no longer fails in the following scopes: subroutine, class, or method. Previously, selecting Go To Definition on "teststructure" in the following, for example, would not work:

    .include "teststructure" repository

However, using Go To Definition with "teststructure" in the following did work:

    .include "teststructure" repository, structure = "teststructure"

Now Go To Definition works in both cases.
We fixed an issue that prevented the Go To Definition feature from displaying all fields when it was used for a repository field declared in this way: “.include <repositoryname> repository, norecord”, unless the field was the first field in the repository structure definition. (It would display the field that the Go To Definition was performed on and the fields below it in the repository structure definition.) Additionally, if the field was the last field in the structure definition, the Go To Definition would fail with an “out of range” exception.
We now handle multiple mainline project filename conflicts as follows:
  • In traditional Synergy, if multiple programs have the same name, TargetExt must be set on all compile includes for those programs or the build will fail. If all compile includes are unique, the TargetExt attribute is not necessary. (TargetExt="dbl" is not allowed.)
  • In Synergy .NET, the TargetExt attribute is not supported. Each compile include must have a unique name or the build will fail.
See “Multiple mainline file naming differences between traditional Synergy and .NET” in the Synergy/DE documentation for details and examples.
When a traditional Synergy unit test fails, standard output content is now included in Test Explorer's results summary.
We fixed an issue that caused build failures during CLI (Command Line Interface) builds when a C# project was specified as a dependency for a traditional Synergy project.
We fixed an issue where IntelliSense completion sometimes caused Boolean operators to be completed with the wrong case. Characters were intermittently uppercased--e.g., ".A" would complete to ".AND.". Uppercased characters are now consistently replaced with lowercased characters to match the selected completion item. 
We fixed the compiler to prevent an unexpected BADACCESS error on a protected generic method.
The compiler prevents a runtime access error from occurring when private fields, methods, or properties whose type is a type argument are inaccessible by giving an E_ACCESS error at compile time. This includes fields used in an object initializer.

Encrypted xfServerPlus connections can now correctly use TLS 1.3 on Windows.
Synergy/DE - 12.4.1.1002
March 14, 2025

Repository

A new "Export type" dropdown has been added to the Generate Repository Schema dialog to support the ability to generate schema to separate files. This makes it possible to use schema files more effectively with version control change tracking. When "Separate files" is selected as the Export type, you must specify the directory to which the files will be generated. The default file naming convention is "type-name.sdl," where type is fmt, tmp, enm, fil, or str, and name is the name of the repository definition, e.g., str-customer.sdl. 
A new checkbox has been added to the Generate Repository Schema dialog to suppress the generation of the header (comment) block at the top of the generated schema file. This makes it possible to use schema files more effectively with version control change tracking. 
Rpsutl has two new command-line options, -esf and -ed, that are used to generate schema to individual files, one for each definition. This makes it possible to use schema files more effectively with version control change tracking. The syntax is 

rpsutl -esf [-ed export_dir] [-d main_file text_file]

If the -ed option is not specified, the files will be created in the current directory. Existing files will be overwritten. 
Rpsutl has a new command-line option (-nh) that suppresses the generation of the header (comment) block at the top of the generated schema file. This makes it possible to use schema files more effectively with version control change tracking. 
While in Move mode, if you switched context to another row in the list with the mouse or scroll bar, it was possible to get a UI Toolkit error or to see multiple sets of [ ] brackets displayed. This issue, which affected enumeration members, fields, keys, relations, local formats, and tags, has been corrected by this tracker and tr#33224.
It was possible to get a Toolkit error, or to see multiple sets of [ ] brackets displayed if, when in Move mode, you switched context to another row in the list with the mouse or scroll bar. This affected Enumeration members, Fields, Keys, Relations, Local Formats, and Tags, and has been corrected. 

Synergy Language

When calling a subroutine as a function, if there's a local external function definition for that subroutine whose return type is ^VAL, we now correctly use the ^VAL function convention (i.e., the function parameters exactly match the subroutine parameters).
We fixed an unexpected level 4 narrowing warning that occurred when assigning i2 to d5.
We added support for -qrntcompat=12050100 to both the traditional Synergy and Synergy .NET compilers. If -qrntcompat is set to 12050100, the DBLV125 system define will also be set automatically.
We fixed a potential problem that could cause an SSL connection to time out early in certain unusual circumstances.
We fixed the compiler to prevent an unexpected BADACCESS error on a protected generic method.
The traditional compiler converts an empty literal string within a USING statement to a default handler (i.e., ()), adding it after subsequent labels. This causes the USING statement to be evaluated out of order, potentially producing unexpected results. Removing this behavior would cause existing customer code to break, so instead the compiler now reports a W_URESULT warning (1046, "Empty alpha literal may cause unexpected results at runtime") when an empty alpha string is used in a USING statement and also a W_NOTEXE warning on subsequent default handlers. To avoid these warnings, we recommend that you examine and potentially remove empty alpha strings from USING statements and test them at runtime. 
We fixed two INVTYPSIZ error issues with ^REF: ^REF([*]structure) no longer reports an INVTYPSIZ error, and ^REF(i) (without a size) now gives an INVTYPSIZ level 3 warning. You can avoid this warning by specifying the integer size (e.g., i4 or i8).
The continuation character is correctly reported as a level 3 warning rather than a NOTSUPT error for -qrntcompat values of 12030100 (12.3.1) and higher.
We fixed the compiler to prevent an unexpected E_INVEXFTYP error when string is used as a type for an external function declaration.
We added a new data reference operation, ^VALDESCR. ^VALDESCR performs the functionality of ^VAL but returns a descriptor that prevents both E_TYPPARM and E_ARGPASS errors when passed into a routine that takes a descriptor while strong prototyping is being used.
Encrypted HTTP connections can now correctly use TLS 1.3 on Windows.
An issue was found where using whitespace in front of a code line prevented the warning "W-NOTSUPT: Continuation character & is not supported after comment" from appearing. This has been fixed so that using a continuation character on the line after a comment will still report the warning regardless of whitespace or indentation on those lines. This change was applied to both traditional Synergy and Synergy .NET.

xfServer

Encrypted xfServer connections can now correctly use TLS 1.3 on Windows.

xfServerPlus

Encrypted xfServerPlus connections can now correctly use TLS 1.3 on Windows.
SDI - 2025.03.1285
March 5, 2025

Visual Studio Integration

The obj\proto directory is now platform specific: an obj\proto directory is created for each built platform. Prior to this enhancement, any build, regardless of platform, would overwrite files in this directory, causing compiler directives and D_ADDR to result in changes in symbol behavior, which led to build and IntelliSense failures.
We added support for displaying "mismatch" for parameters when hovering over subroutines/functions.
We added the ability for a user to disable the SDI update notification window by setting a registry value named SkipUpdateCheck on HKEY_CURRENT_USER\Software\Synergex\SDI to true.
We improved build message handling from the script compiler in SDI.
When a Synergy .NET multiple mainline project is built from the command line, the mainline files that are built in the process are now listed in the output.
When you are offline or if there are service disruptions, the SDI update window will display "N/A" for the version and message, and the window will not display automatically.
Previously in certain scenarios, .NET/.NET Framework multiple mainline projects could incorrectly write background compile input and log files to directories other than the multiple mainline project's intermediate output directory. This has been resolved.
Go To Definition no longer fails to execute for repository and library includes when they are placed in the global scope.
We fixed a compatibility issue that was causing a build failure for Script projects on machines with SDE versions lower than 12.3.1.
We updated our NuGet dependencies for SDI to address moderate/high severity vulnerabilities. As a result of these updates, we have increased our minimum supported version of Visual Studio to 17.8. To be able to install newer versions of SDI, you must use Visual Studio versions 17.8 or higher.
We improved the build error that is generated for a Synergy project when the "Working directory" field (on the Application page of project properties) specifies an invalid directory.
The "Committed by pressing the space bar" option on the IntelliSense page for Synergy DBL text editor options has been removed because it was conflicting with the "Default IntelliSense completion mode" option in the Visual Studio Advanced text editor options. (It would sometimes prevent this default from being used.) Synergy completion mode behavior is now controlled by the "Switch between automatic and tab-only IntelliSense completion" command (on the Edit > IntelliSense menu), which derives its initial state for every Visual Studio session from the "Default IntelliSense completion mode" setting. This determines whether an item is selected (boxed with a background highlight) or suggested (boxed without a background highlight) by default in completion sessions. When an item is selected, any valid commit character should complete the session with the selected item. When an item is suggested, only tab should complete the session with the suggested item. Any character or key other than those should close the session without completing the selected or suggested item. This behavior may be slightly different than in previous releases but should be more consistent going forward.
The dblnet compiler now emits a code that ensures a static constructor is run when compiling with -netcore, even if no static fields in that class are being set.
A build error previously occurred while building .NET multiple mainline projects on an environment with .NET 9 installed for a missing _ChooseAppHost target. The target dependencies for .NET multiple mainline projects have been updated to include a different target that exists in both .NET 8 and .NET 9.
For the Synergy .NET compiler, using the -doc option to produce XML documentation files will no longer generate multiple XML elements that have the same name attribute. This applies to documentation comments (starting with three semicolons on each line) that precede partial classes, partial interfaces, partial structures, and partial methods. For partial methods, the documentation comment on the method's implementation will be used for XML, and the documentation comment on the method's declaration will be ignored. For partial types (classes, interfaces, and structures), any partial type having a particular name (e.g., ExampleClass) will only use the last partial definition with a documentation comment to produce XML. The documentation comment for all other previous partial types with that same name (e.g., ExampleClass) will be ignored. Whenever a comment is ignored, a W-XMLDOC level 4 warning is reported, indicating the method or type associated with that comment. This change supports utilities that read XML documents but can't process duplicate names.
We fixed a concurrency issue that would intermittently cause a type that was designated as a boxed structure (such as @System.Guid) for a field, property, or parameter from an assembly to be resolved as @System.ValueType, which caused various type mismatch compiler errors.
A decimal descriptor can now be passed to an alpha parameter when -qrelaxed:param is specified.
.NET multiple mainline projects now base the output directory for documentation files off of the synproj file location rather than the location of the mainline file.
We fixed an issue where "Other options" specified on the Compile page for traditional Synergy projects were not passed to background compile operations, preventing IntelliSense from reflecting these settings.
An issue was found where using whitespace in front of a code line prevented the warning "W-NOTSUPT: Continuation character & is not supported after comment" from appearing. This has been fixed so that using a continuation character on the line after a comment will still report the warning regardless of whitespace or indentation on those lines. This change was applied to both traditional Synergy and Synergy .NET.
We fixed an issue that prevented linker errors from causing build failures for traditional Synergy projects.
A warning will now be produced when a referenced project does not exist, making error reporting more user-friendly.
The .intellisense folder is no longer generated in the same location as the multi-mainline source files. It will now always be generated in the same directory as the multi-mainline .synproj.
We resolved an unexpected failure that occurred when building a solution with an ELB project with the "-qvariant" option set on the project's compile property page.
We resolved an issue that sometimes caused projects to be skipped during Visual Studio builds. This issue primarily affected Visual Studio builds of Synergy repository projects, which use the SynergyDE build NuGet package, after a fresh clone of a code repository and prior to running a NuGet restore.
Handling for build error and warning messages has been updated to produce messages for all mainlines in a .NET multiple mainline project instead of just one.
We resolved an issue where multi-mainline projects were failing to trigger a minimal analyze after loading or when edits were made to the multi-mainline file.
A FOREACH iteration over a generic previously caused a TYPMISMCH error when the generic was used before it was declared. This has been fixed.
For multiple mainline projects that do not have a StartupObject set, selecting mainline files from Solution Explorer will no longer display the following error message: "Object reference not set to an instance of an object."
The compiler now reports a W_URESULT warning (1046, "Empty alpha literal may cause unexpected results at runtime") for an empty alpha literal within a USING statement, because it will match everything and subsequent USING statements will never be executed. To avoid this warning, we recommend that you examine and potentially remove empty alpha strings from USING statements and test them at runtime. 
We fixed an issue that caused "DBP is already in use" errors during the background compilations used to generate IntelliSense information. These errors prevented the creation of new DBP files, which are necessary for the generation of new symbols.
Compiling a file that contained a global non-CLS structure and whose name included a hyphen character caused an unexpected ILASM error. This has been fixed.
When the ^VARIANT, or -qvariant, option is set in the project's compile property page, it will display the number that was input when hovering over the compiler directive in the Visual Studio editor.

LTS
January 27, 2025

Installation

The environment variables VORTEX_HOME and GENESIS_HOME are used for different purposes by Connectivity Series products, but both point to the same location by default on Unix. Users may want to redirect GENESIS_HOME to point to the location of system catalogs, but VORTEX_HOME should not be modified. However, the setsde script used the value of GENESIS_HOME to set VORTEX_HOME, so if a user edited setsde to change GENESIS_HOME, that change might also change VORTEX_HOME and prevent Connectivity Series from working correctly. To avoid this problem, we've modified all newly created copies of setsde so that GENESIS_HOME and VORTEX_HOME are set independently. Now if GENESIS_HOME is modified in setsde, it shouldn't affect VORTEX_HOME or any other variable. 

Repository

Previously, if the last line of a schema file didn't have a carriage return at the end, that entire line would not be parsed and processed. This has been fixed. 

SQL Connection

A period in the directory path no longer causes a "Keyfile not found" error for SQL Connection with encryption.

Synergy Language

We eliminated the STRWRN error and fixed the runtime memory corruption that occurred when a structure with initial values was used in a local data field of type structure and the scope where it was used didn't have an object handle. 
We added .NET runtime support for the SYN _REPORTEVENT routine.
We added support for OpenSSL 3.2 and above on OpenVMS and Unix.
When making an HTTP document transport API call that referenced a PEM file certificate whose path contained a period ("."), the API unexpectedly returned a "Keyfile for certificate cert not found" error. This has been fixed.
For dbs.exe and the .NET runtimes, when a file with Unix line endings (LF) instead of Windows line endings (CRLF) was read via redirected input to TT:, the READS would terminate early with a $ERR_EOF error. In addition, if a line was terminated by EOF rather than a line terminator, the text on the line was ignored. This has been fixed.
An "Invalid date” ($ERR_INVDATE) exception from %WKDAY is now reported immediately at the correct line.
Opening two channels to TT: in .NET and closing the second no longer results in an unhandled exception. In addition, this avoids an unexpected exception when closing a Toolkit .NET program while running under a debugger.

UI Toolkit

The UI Toolkit routines %I_INFO and U_RESIZESB were previously inaccessible on OpenVMS. This has been fixed.

xfODBC

Queries that contain multiple joins on multiple tables no longer result in a VTX4 driver crash.
The LIKE key setting finds and remembers the correct column regardless of the operand's position.
The correct number of rows is now returned on a query that uses TOP or SKIP to select a list with an integer literal in the first position.
We added support for ODBC sort work files used by Group By and Order By on 32-bit Unix platforms.
The sorting operation no longer results in duplicate values in queries with both the DISTINCT keyword and an outer join.
Sometimes a TFISEEK "Invalid argument" error occurred when performing Order By or Group By. This has been fixed.

xfServer

We fixed a problem occurring in rare circumstances (related to certain network configurations) where opening a connection to xfServer on OpenVMS could result in the xfServer processes crashing with an access violation.
SDI - 2024.10.2239
October 25, 2024

Visual Studio Integration

The Synergy .NET compiler now reports a level 4 E_PASSUR warning when a field, record, or group is passed to a group parameter that is larger. (Without this, accessing a field in the group outside of the size of the passed-in alpha would cause a runtime exception.)
We fixed an issue that caused Solution Explorer to indicate that it was infinitely loading (it displayed a continuously spinning icon) when a multiple mainline project was expanded in Solution Explorer.
The continuation character is correctly reported as a level 3 warning rather than a NOTSUPT error for -qrntcompat values of 12030100 (12.3.1) and higher.
The Synergy .NET compiler no longer mistakenly reports a level-4 NARROWING warning when assigning an i2 value to a d5.
The syn_reportevent() routine is now supported for Synergy .NET when qrntcompat is set to12050100.
We added diagnostic logging to dblnet to report information about asm2dbp. The asm2dbp program is a utility related to the Synergy .NET compiler that takes .NET assemblies and generates DBP files (prototype files). These diagnostics can be enabled by setting the environment variable ASM2DBP_DIAG to 1. To disable the diagnostics, delete the ASM2DBP_DIAG environment variable. Log files are written to the Synergex directory under the LocalAppData path (i.e. navigate to LocalAppData/Synergex where LocalAppData is an environment variable containing a directory path on Windows).
We updated the Synergy .NET compiler so that it now supports D_ADDR as a default parameter type.
We fixed an issue that caused hover-over IntelliSense for an "i" data type with a set size (e.g., "testvar, [4]i4") to display incorrectly (e.g., as "testvar, [#]i44").
The SDI Update window is no longer displayed in Visual Studio when the latest version of SDI is installed.
We fixed an issue that sometimes caused a SynergyTasks.DBLinkT error when a multiple mainline project had more than one mainline with the same name but different file extensions (e.g., mymain.dbl and mymain.abc).
Synergy .NET now supports ^REF parameter types that are value types, including non-descriptor integer types and CLS structures. (Other ^REF types cause E_NOTSUPT errors.) Note that the caller must also encapsulate argument with ^REF and the type must match exactly; otherwise an E_TYPPARM error will be reported.
With traditional Synergy projects, the following settings (set on the Compile page of project properties) were not passed to background compilations used behind the scenes for IntelliSense: 
  • Require prototype usage (-qreqproto), 
  • Define all undefined functions as ^VAL (-X, -qimplicit_functions). 
This issue sometimes caused unexpected red squiggles when editing in Visual Studio while these options were set.
With Synergy .NET, when INIT was used on a fixed or pseudo array that had no initial value, it cleared only the first element of the array. This has been fixed so that it now clears the entire array, which matches INIT's behavior with traditional Synergy.
The "Latest" setting for "Target Synergy runtime" (on the Build page of project properties) now selects version 12.5.1, which currently corresponds to the 12.4 feature release. Previously "Latest" targeted 12.3.1.
The Synergy .NET compiler now reports an E_NOFXD level 3 warning when performing # rounding on an expression that includes implied-decimal (d.) operands.
New .NET and .NET Standard class library projects will now have "3 - Don't display warning levels higher than 3" as the default "Set the warning level" setting. ("Set the warning level" is a setting on the Compile page of project properties.) Previously, the default setting for this was "0 - Don't generate any warnings" for these project types.
Startup Object highlighting now persists when an multiple mainline project is closed and then reopened. Previously, the highlighting would disappear when the project was reopened, though the Startup Object setting was still in force.
We fixed an issue that caused inconsistent red squiggle behavior for erroneous code in Synergy code files when these files were opened, as code was modified on the same line as erroneous code (which sometimes caused red squiggles to briefly appear), and when modifying code on other lines.
The Synergy .NET compiler no longer mistakenly reports an INVCALL error on a %MEM_PROC call when a subsequent lambda expression includes a subroutine call of MEM_PROC.
We fixed the "Using" snippet so that it now results in valid code.
The default runtime is now 12030100 for dbl, dblnet, and dblink. This is the default version if -qrntcompat is not specified.
The Synergy .NET complier now reports an E_ATOS error when a group or record is passed as an argument to a parameter that's a larger structure. Previously, this caused an exception (SynDataException).

License Manager

The license for a Windows xfServer/xfServerPlus client connecting to a Linux server using license forwarding is now released properly when the client completes.

Synergy Language

The parser no longer reports an unexpected E_INVTYPSIZ error due to an earlier FOREACH-AS statement.
When creating an ISAM file using a file description (FDL, XDL, or PAR), NULL key values that are specified using a quoted string ('0', " ", or '\0') are now converted to the correct values as documented in the ISAMC documentation.
Previously, when ctutl was used on low-overhead change tracking data (e.g., with no duplicates or fixed-length records), records that were freed by either the free or rollback operation were deposited in the free list with a partially cleared free list link, causing an %ISUTL-E-28: Data freelist error. This has been fixed.
Freeing a snapshot (down to 1 or 0 remaining snapshots) previously could cause DELETE entries to be malformed, causing a file verify (isutl -v) to report a data mismatch with leaf or invalid RFA errors. This has been fixed.
The traditional Synergy and Synergy .NET 12.3 compilers now recognize the DBLV123 system define when -qrntcompat is greater than or equal to12030100.
Patching an ISAM file that contains change tracking using isutl -p no longer loses snapshot timestamp information. Affected patch options include enabling or disabling the network encryption flag and enabling or disabling resilient and full resilient.

UI Toolkit

We fixed a regression in the script compiler that could cause a "Bad index" error at runtime if a menu column in a window script used lists to group related entries, and the runtime attempted to enable or disable a list of entries in the column. Any window library built with version 12.3.1.1014 of the script compiler (or any 12.2 version) should be rebuilt to take advantage of this fix.

Visual Studio Integration

Microsoft is ending support for .NET 6 in November of 2024 (https://dotnet.microsoft.com/en-us/platform/support/policy/dotnet-core), so we have updated Synergy .NET project types to default to .NET 8.
Previously, if a build failed for a mainline in a multiple mainline project due to link errors, the other mainlines were not built. Additionally, builds did not occur in parallel. We updated this behavior so that builds for multiple mainline projects occur as if each mainline were an individual project. Mainlines are now built in parallel, and a mainline build failure due to link errors does not prevent other mainlines from building.
The debugger now steps correctly for a conditional statement for a single line at the end of a begin/end block in Synergy .NET code. Previously, the debugger would incorrectly step to the single line even if the conditional statement evaluated to false. For example, the debugger would step to the Console.Writeline line of the following:

begin
   data ok, boolean, true
   if (!ok)
      Console.WriteLine("Fail")
end
We fixed issues with paths and output file handling that prevented the up-to-date check for Synergy .NET and .NET Framework multiple mainline projects from functioning correctly, causing these types of projects to rebuild with every solution build. 
When a routine call is used for an initialization value in the data section, the compiler now provides more detailed and descriptive error text ("Feature not yet implemented: Runtime initialization of <field> not supported") for the E_NOTIMPLE error that it reports on the offending line.
We fixed an issue that prevented .NET and .NET Framework multiple mainline projects from building when the project folder name included a space.
When Visual Studio instances are running under different user contexts (e.g., a non-admin instance and an admin instance), attempts to retrieve the version information no longer result in unexpected exceptions due to permission restrictions. We enhanced SDI to handle such cases gracefully, ensuring reliable version information retrieval regardless of the user context.
We fixed an issue that prevented the WPF designer from loading for C# projects. The WPF designer no longer loads by default for Synergy WPF projects (because these project types are deprecated), but it does load for Synergy WPF projects when you select the designer view from the XAML view, and it now loads for C# projects when a solution includes both C# and Synergy projects. 
We fixed an issue that prevented the build system from detecting when a script project was out of date due to updates to the referenced repository.
For Synergy .NET projects, the option to permanently delete a file from the Solution Explorer did not update the .synproj file, causing subsequent attempts to build or rebuild to result in an error stating that "Source file 'filename' does not exist". (This option is invoked by right-clicking the file, selecting Delete from the context menu, and then clicking the Delete button.)
D_NETCORE is now displayed for .IFDEF IntelliSense completion. 
When the get or set method of a property had capitalized letters (e.g. Get/Set or GET/SET), an unexpected E-NOOVR error ("No suitable method/property found to override") would occur when trying to override the property. This has been fixed so that the E-NOOVR error will no longer occur, but a W-CHGCASE (change case) warning will be issued instead. The W-CHGCASE warning indicates that the case of the overriding get or set method was automatically changed to match the base property. To remove this warning, make sure that the case of the base property methods exactly match those of the overriding property methods.
We fixed an issue with the way the SDI Update window retrieved values from the Windows registry. This issue would sometimes result in NullReferenceException and cause Visual Studio to crash. 
The compiler for Synergy .NET no longer mistakenly reports an E_INVTYPSIZ error on a line that follows a FOREACH AS statement. The workaround for this issue was to eliminate the AS part of the FOREACH.
We fixed an issue that caused "invalid output path" build errors when building .NET Multiple Mainline projects.
With a Synergy project that is source controlled via TFS (Team Foundation Server), using the "Get Latest Version (Recursive)" function with the Synergy project would fail with an "Unspecified Error". This has been corrected.
The Go To Definition feature now works for .NET multiple mainline projects. Previously if you used this feature for a function for which another version existed in another project, Go To Definition would not always go to the correct file.
When opening a Synergy .NET solution in Visual Studio, an extra console window with the title asm2dbp.exe briefly appeared and disappeared upon loading the solution. This has been fixed so the extra window is no longer shown. To obtain this bug fix, both SDI and the Synergex.SynergyDE.Build NuGet package must be updated.
We fixed an issue that sometimes caused the Visual Studio UI to hang due to processing colorization changes when editing Synergy files. This was particularly true for large files with many method calls, and it resulted in delays when scrolling through the file or when typing. 
We fixed an issue with IntelliSense for Synergy .NET programs that was causing intermittent delays and missing display data. 
Using a global common in Synergy .NET no longer causes an unexpected ILASM error.
We fixed an issue that caused debugger information to fail to appear when Break All was used immediately after launching the Visual Studio debugger for traditional Synergy code. For instance, the Call Stack window would sometimes be blank, and in some cases the editor would become blank.
PEVerify is now run for all build outputs, including DLL and EXE build outputs, for .NET Framework multiple mainline projects.
Synergy/DE - 12.4.1.1001

License Manager

The license for a Windows xfServer/xfServerPlus client connecting to a Linux server using license forwarding is now released properly when the client completes.
If the backup server port was different than the primary server port, the backup server was being reported as "inaccessible" when lmu was run on the primary server. This has been fixed to properly connect and report the status of the backup server.

Synergy Language

The compiler was reporting an unexpected PROTOMISMC error on a structure argument where the structure was nested previously in the class, even though there was a public structure of same name. This has been fixed.
The compiler no longer reports an unexpected NOTSUPT error when ^NAMEOF contains a parameter group and the source is compiled with the -qcheck option.
When creating an ISAM file using a file description (FDL, XDL, or PAR), NULL key values that are specified using a quoted string ('0', " ", or '\0') are now converted to the correct values as documented in the ISAMC documentation.
A FOREACH loop with an implicit element type sometimes caused an internal compiler error if the element type was a user-defined nested class declared after the loop in the same file. FOREACH loops now infer the type properly regardless of where the element class is placed in the file.
Performing a free operation on change tracking snapshots no longer blocks I/O by other processes, allowing frees to be performed on live data files. 
An E-NOTSUPT error ("Token is not supported") will be reported on a FOREACH loop that iterates over a real array that is a class or structure field. Previously, the FOREACH only got the first element of the real array in a class or structure. The new error message indicates that a FOR-FROM loop will work instead. There was also a problem where putting a dynamic array and a real array into a class and iterating over both using FOREACH caused a segmentation fault at runtime. The NOTSUPT error will prevent this case as well.
An "Assembly not found" error no longer occurs when a C# project references a Synergy .NET project with a Synergex.SynergyDE.synxml NuGet package reference. (To fix this problem, we strong-signed assemblies that are part of Synergex.SynergyDE.synrnt NuGet package.)
An access violation no longer occurs when returning a literal for a method whose return type is an array of boxed alphas.
Freeing a snapshot (down to 1 or 0 remaining snapshots) previously could cause DELETE entries to be malformed, causing a file verify (isutl -v) to report a data mismatch with leaf or invalid RFA errors. This has been fixed.
Previously, when ctutl was used on low-overhead change tracking data (e.g., with no duplicates or fixed-length records), records that were freed by either the free or rollback operation were deposited in the free list with a partially cleared free list link, causing an %ISUTL-E-28: Data freelist error. This has been fixed.
The correct SnapshotInfo entries are now loaded into the ChangeTracking object that are reflected in the file. There is always one and only one entry of SSType Beginning, which contains the earliest snapshot number (either the initial 0 or the last freed snapshot) with DateTime representing the time of file creation, last clear, or last freed snapshot) with all Inserts, Updates, Deletes, and Ulinks set to 0. For each applied snapshot, there is one SSType Snapshot that will contain its unique snapshot number, the datetime it was applied, and all Inserts, Updates, Deletes, and Ulinks that were recorded while that snapshot number was the current snapshot (or SSType Ending) prior to that snapshot being applied. Lastly, there is always one and only entry of SSType Ending whose snapshot number is the current snapshot (the snapshot currently recording changes to the file) with DateTime representing the time the ChangeTracking object was created (or the time the last Refresh() method was called) with Inserts, Updates, Deletes, and Ulinks reflecting the changes since the last applied snapshot. Due to this change, use of these snapshot entries may result in different behavior. Prior behavior included change accumulators always being recorded in the prior snapshot and never including the last snapshot entry.
A warning has been added to the 32-bit traditional Synergy compiler. (It does not apply to 64-bit traditional.) For addition, subtraction, multiplication, and division between two values, a W-INVCAST warning ("Invalid cast") will now be given if casting one or both values to i8. However, the warning will not be given if either value is already an i8 field, literal, etc. The purpose of this warning is to indicate that casting to i8 has no effect on whether the current expression does 32-bit or 64-bit math; actual i8 variables should be used instead. To disable this warning, pass the option -WD=699 to the compiler.
A level 4 ATOS warning ("Passing alpha to structure requires alpha of at least structure size") now occurs when a group or record is passed as an argument to a larger structure parameter.
Using a Windows drive-relative path specification (e.g., c:prog.exe) now runs the expected program when running ctutl.exe, ismvfy.exe, or irecovr.exe. 
When you run isutl -c, you will now be prompted to confirm with "y" or "n" that you want to clear the ISAM file. If your file specification includes a wildcard, for each file, you'll be prompted, "You are about to clear filename. Do you wish to continue: (Yes/No/All/Quit)?" Answering "y" means clear this file, "n" means do not clear this file, "a" means clear this and all subsequent files, and "q" means do not clear this file and quit now. We also added a -y option to isutl -c, which suppresses the confirmation query by automatically responding "y".
Patching an ISAM file that contains change tracking using isutl -p no longer loses snapshot timestamp information. Affected patch options include enabling or disabling the network encryption flag and enabling or disabling resilient and full resilient.
When a string variable is used as the loop element for a FOREACH loop and the collection is a real array of type alpha, a new TYPMISMCH error ("Type mismatch between type and type") will be reported to avoid an issue at runtime. The user can change the string variable to an alpha variable in order to get the loop to work.
A level 4 W_PASSUR warning ("Passing alpha to group of larger size for parameter <#parmnum> could give unexpected results") now occurs when an alpha field, group, or record is passed as an argument to a larger parameter group.
The parser no longer reports an unexpected E_INVTYPSIZ error due to an earlier FOREACH-AS statement.

xfODBC

We fixed a problem in the xfdba utility that caused it to report an invalid character when initializing users and groups or setting a blank password for a user.

xfServer

We enhanced the xfServer logging that occurs during log-in failure to help diagnose RUSER setting problems. We also updated the Synergy/DE documentation with clarifications on using the setruser utility and RUSER environment variable.

Visual Studio Integration

We added templates for the "Multiple Mainline (.NET)" and "Multiple Mainline (.NET Framework)" project types to the Synergex.Projects.Templates NuGet package.
The "dotnet add" and "dotnet add reference" commands are now supported for all project templates in Synergex.Projects.Templates.
We fixed an issue with IntelliSense-related processing for SDI that caused unintended errors and red squiggles to appear intermittently (though these did not affect builds).
We fixed an issue that prevented conditional breakpoints from working with Synergy .NET projects. 
We fixed an issue that caused Visual Studio to crash intermittently when editing DBL files in traditional Synergy projects. This issue was caused by a threading-related access violation in DBL’s IntelliSense processing.
We fixed a problem with the SynNETUnitTest project template (in the Synergex.Projects.Templates NuGet package) that caused projects created from this template to have an incorrect import statement.
We fixed an issue that caused a "missing method" exception at runtime when using JsonElement's indexer. This fix also prevents NOPRPMTH errors from occurring when property method names differ in case from "get" and "set" (e.g., "Get" or "Set") and the property is from another assembly.
We fixed a mismatch between the name of the .dbl file that's added to a newly created traditional Synergy unit test project created using the syTradUnitTestProj template (in the Synergex.Projects.Templates NuGet package) and the .dbl file specified in the .synproj file for the project.
We fixed an issue that sometimes caused an error when a build was stareted in Visual Studio while project property pages were open. 
We fixed a Synergy .NET compiler issue that resulted in an access violation for an overloaded method with a parameter that was an array of boxed bytes.
We fixed an issue that prevented Start Debugging from working in Visual Studio 2022 version 17.10.x.
We improved SDI's problem manager logging by implementing a log rotation mechanism that prevents memory leaks.
New and unexpected %DBL-E-REFTYPMSMC errors no longer occur after updating SDI when there have been no source changes.
An access violation no longer occurs when returning a literal string for a method whose return type is a boxed alpha array.

License Manager

We now prevent a bad registration string starting with "AAAAAAA" from putting a system into a forced expiration due to a registration string mismatch. Instead, we just log the fact that it was encountered.
Using lmk -nc <server> no longer erroneously updates a local machine's registry when <server> has a backup server. This fix avoids subsequent licensing issues for version 10.1 or older clients.

Synergy Language

 We fixed an access violation in dblproto that occurred when prototyping multi-mainline projects.
In the traditional compiler, using the Json.JsonElement.ValueKind property of system enumeration across many sources in the same compilation unit no longer causes an access violation.
Using %INTEGER with magnitude 8 on a 32-bit system now returns the full i8 value.

xfODBC

If a query generates a sort file and the query fails due to a timeout or sort buffer overflow error, the vtx4 driver now deletes the sort file as expected instead of leaving it after the connection is closed.
Timeouts set with "SET OPTION TIMEOUT" will now correctly apply to all queries that haven't fetched any rows within the specified time. Note that this timeout applies to each fetch operation but not to the total length of time for a query. (In other words, massive result sets will still take a long time to return, regardless of timeout value.)

Visual Studio Integration

SDI now supports Synergy .NET projects with multiple Synergy mainline programs. As part of this support, SDI includes two new project templates, “Multiple Mainline (.NET)” and “Multiple Mainline (.NET Framework)”, that enable you to create .NET 6+ or .NET Framework projects with multiple Synergy mainline programs that share project settings and references. A project created with one of these templates results in an application that is distributed as multiple EXEs. Each mainline source file results in a separate executable that can be run and debugged separately.
We added an experimental option to reduce load times for Synergy projects. To invoke this feature, set the SDI_FAST_MODE environment variable to any value before starting Visual Studio. Note that this functionality may cause project references to load in an incorrect order, which could put a project in an invalid state.
We now prevent a NullReferenceException error at runtime when declaring a sized descriptor parameter on an ASYNC method.
The compiler for Synergy .NET now reports an IVBAD error if an initial value is provided for a boxed enum or an array of boxed enums.
We fixed an issue that prevented colorization from being refreshed for code in an .IFDEF statement when the .IFDEF condition was modified.
We resolved problems with IntelliSense showing unexpected errors/red squiggles on the wrong line when opening a file in the Visual Studio editor.
When the final parameter for a routine call is "end", and this is on a separate line that begins with an ampersand (&), IntelliSense no longer mistakenly interprets "end" as the conclusion of a BEGIN-END block. Previously, this was misinterpreted, resulting in incorrect indentation for subsequent lines of code.
Casting an enumeration property to an integer no longer causes an error to occur when the compiled program is checked with PEVerify or ILVerify.
We reinstituted a warning message the displays when prototype files (.dbp files that are used internally for IntelliSense symbols) are locked for I/O for extended periods. 
We fixed the parser to properly report a lambda syntax error when the return type is incorrectly declared on a lambda.
With Synergy .NET, the "Working Directory" setting, which is set on the Application page of project properties, is now stored as a relative path (relative to the solution directory).
We fixed an issue that caused a NOTSUPT error ("due to incorrect size...") when there is a structure is within a record, group, or structure. Additionally, the workaround for this issue (DBLDIR:\bin\dblnet.hcs) is no longer supported.
We fixed an issue that caused unexpected results for arithmetic operations such as subtraction with two i4 variables that had been cast to i8.
The compiler for Synergy .NET now reports an E_NOSPECL error when the braces for an inline lambda expression are missing.
We improved logging that occurs when a catastrophic failure occurs while a background compile is running to generate IntelliSense symbols for a .NET or .NET Framework project. This logging now writes the error text to the background.log file to make it easier to diagnose background compile failures with these platforms.
We fixed an issue that prevented the debugger from breaking on breakpoints that precede a lambda in an ASYNC method.
The Synergy .NET compiler no longer mistakenly reports an E_NTTREF error for a parameter that is a structure from an assemble and that structure is defined in a namespace that has a class with the same name as the namespace.
Synergy .NET Framework projects now support the PackageReferences NuGet package management format. 
A FOREACH loop with an implicit element type sometimes caused an internal compiler error if the element type was a user-defined nested class declared after the loop in the same file. FOREACH loops now infer the type properly regardless of where the element class is placed in the file.
We fixed an issue that sometimes caused the error "SynergyTasks.DBLinkT task failed unexpectedly" when building a solution.
We fixed an issue that occurred when casting multiple function arguments to a Synergy integer type. Previously, a value cast in the last argument replaced values for the previous arguments in the same statement.
We fixed an issue where the Synergy DBL text editor formatting options did not get applied until the Tools > Options dialog page had been opened.
We fixed an issue that sometimes prevented IntelliSense from loading for Synergy .NET projects.

License Manager

The Synergy License Manager will no longer freeze (blocking license clients such as dbl, dbr, dbs, etc.) when running certain Linux programs (like tmux).

SQL Connection

We fixed a regression with SQL Connection (introduced in Synergy/DE 12.1.1.3292) that could cause a memory leak when connecting to SQL Server, resulting in excessive memory usage over time.

Synergy Language

We fixed an issue with the traditional debugger that caused a segmentation fault when debugging a program in Visual Studio. A check for the length of a data chunk was updated to mitigate the issue that occurred during processing of debug information and resulted in invalid memory access.
We fixed a problem in the Synergy HTTP document transport API that could cause a socket timeout when making an HTTPS request using a proxy..
We resolved an issue with the traditional debugger that occurred during an attempt to run the same OPENELB command multiple times. After saving debugger settings by running the SAVE command, the output file contains only the unique ELBs that were opened during the debugging session.
(.NET) We fixed a Stack Overflow exception in the HTTP document transport API that occurred when sending large documents in post, put, patch, and delete requests by updating the way we allocate memory for documents in the request.
When SYN_RESIZE_SCALE was used, window elements often had incorrect dimensions when windows were restored from maximized. The dimensions of the window and its components should now be consistent after restoration.

UI Toolkit

In versions 11.1.1c through 12.1.1-3292, the default button size was 10, which caused size and scaling problems for existing applications that expected it to be 9 as in prior versions. This default button size is now 9 again. As most customers default to Consolas;10 from the default app size, they can add BUTTON=SYSTEM;10;A in the font section of synergy.ini to restore the post-11.1.1c behavior. If SYN_RESIZE_SCALE is used, ARIAL;10;A is preferred to SYSTEM:10:A.
In 11.1.1c through 12.1.1.3292, the default font for the status bar was incorrectly changed from Arial to Consolas. (Consolas is a monotype font, while Arial is a proportional font.) Arial is now used by default.
When using the new BUTTON= in the fonts section of synergy.ini, a size other than 9 or 10 did not result in correct button sizing. This has been fixed.
