Version 2.3.7 08 AUG 2024
Linkar Server
0001871: Bug fixed in Uniobjects against Linux databases
When using Uniobjects with Linux databases the database lines die after a period of inactivity. Linkar Server sends an activity refresh every 240 seconds in keepalive style to avoid this situation.
The refresh time can be configured in the KEEPALIVE_INTERVAL attribute within the PROFILE node. Values in seconds greater than 10 seconds indicate the new refresh time and values less than 10 disables the refresh.
Version 2.3.6 10 JUN 2024
Linkar Manager
0001837: Remove all calls to external urls, to avoid problems on servers with outbound limitations.
For the correct execution of Linkar Manager on servers with limited internet access, all calls to style and javascript urls have been removed.
For a correct working, it is only necessary to have access to the following urls:

0001700: Send and Receive Timeout Management in Linkar REST API
The REST API operations of LinkarManager against LinkarServer were running with fixed timeouts of 8 seconds on both send and receive.
Now the same timeout values are being used as the EntryPoint associated to the APIKEY.
Version 2.3.4 15 DEC 2023
WARNINGS (if you already have Linkar Suite installed)
You must upgrade D3 database MV Components
Linkar Framework. If you are using any Linkar Framework Library, you must upgrade to version 2.3.1 to fix the error shown below.
Linkar Server

0001691: Fixed communication error between Client and Linkar Server in cases of multiple requests at the same time.
0001688: New Timeout settings in Database operations.
Timeouts extended to check if a Database session is available to run the operation.
Linkar Manager
0001692: Close Database Session button. End of operation control
Closing a database session now checks if an operation is in progress, and waits for it to finish before beginning the logout process.
Linkar Framework
0001694-0001695: Fixed communication error with Linkar Server Sockets.
Linkar Framework sometimes crashed when it did not receive responses from Linkar Server and caused CPU spikes.
MV Components
0001684: D3. Added new condition for killing operation Kill lines
Added a new condition to disconnect a line that is disassociated from Linkar Server in waiting status, in MVSP and Socket connection types

Version 2.3.1 10 NOV 2022
WARNINGS (if you already have Linkar Suite installed)
You must upgrade the MV Components.
Linkar Server
0001320: Linkar Server ready to accept requests from Linkar Web Services
0000902: Fixed Bug. EntryPoint Lite Version with on-demand lines only not starting.
0000908: Errors in the line counter of opened databases on Pro version when there is a connection problem.
0000942: Alarms. Data validation on email sending, Mailto, smtp server.
0000945: Fixed Bug on statistics with large operations.
0001025: Added new option to build JSON with numeric and boolean types.
New option in Master and EntryPoint parameters to activate JSON generation with numeric and boolean types. If not activated, all JSON values generated will be of string type.
0001028: Different IP listener for each EntryPoint.
Now an IP listener can be defined for each EntryPoint. If not assigned, Linkar Server IP will be used. Especially useful to avoid exposing all EntryPoints to public network, or vice versa.
0001158: Socket type connections. Reconnection attempts extended to 5.
Before current version, 3 connection attempts to the Socket were made when opening an EntryPoint. Now, 5 attempts extension increases connection success.
0001175: High CPU usage in Linkar Server
Two new parameters included in EntryPoint configuration, named SOCKET_RECEIVE_TIMEOUT and SOCKET_SEND_TIMEOUT.
Before current version, both were configured to 0 value, and in situations like attack or failed connections, that would generate an endless reception thread, causing high CPU usage.
It is recommended to put SOCKET_RECEIVE_TIMEOUT value to 10 seconds and SOCKET_SEND_TIMEOUT to 60 seconds in order to avoid endless waiting times that would originate high CPU consumption.
Two new input boxes have been created in Linkar Manager / Configuration / EntryPoints.
0001194: New Low message to inform about attacks made to Linkar Server IP
**S0016 - WRONG HEADER RECEIVED** (Includes information of the IP that sent the petition)
0001235: UTC date to local change in Linkar Server and Manager logs.
Local Date of the server where Linkar Suite is installed will be used in order to ease reading.
Linkar Schemas
0000980: Improved EqualTO property from Schemas' Properties.
schemaname|propertyname syntax is no longer needed. Indicating Schema Name is enough to define EqualTo.
MV Components
0001252: New version MV Components 2.3.0.
MV Components update required.
0000903: Fixed Bug in "Use Common Blocks for the 100 most used files" feature
Only when using the "Use Common Blocks for the 100 most used files" switch in the EntryPoint configuration.
Now the files that are out of the ranking of the 100 most used files are closed with CLOSE statement.
0000922: Fixed Bug in GetTable method.
Reading MV or SV tables was generating two extra columns to the right.
0000947: Fixed Bug in GetTable function SQL Mode plane table
Now we make sure to always take the first multivalue in those fields defined as flat.
0000958: Fixed Bug when ItemID was empty in Select from LkSchemas and LkProperties methods.
0000964: Improved data type calculation.
The calculation of integer and decimal datatype has been improved. MRx conversion and decimal separator value in ENTRYPOINT PARAMETERS are taken into account.
0000966: Fixed Bug in Update Function in JSON or XML format
If any xml or json tag is missing the attribute is not modified. Previously it was being saved empty.
0000978: Extended LKPROPERTIES functionality to JSON_DICT, JSON_SCH, XML_DICT, XML_SCH.
Now the result in these formats will create Multivalue and Subvalue field objects. The output in JSON and XML format have not changed.
Linkar Framework version 2.xx or higher is required.
0000979: LK.CHECKDICTS command is now executable from data account.
0001198: UpdatePartial function. Use of Write instead of WriteV.
UpdatePartial function enables recording one or more attributes from a register. Before this change, WRITEV sentence was used for each attribute on recording.
Now the WRITE sentence is used in order to optimize recording and letting execution of possible Triggers.
0001203: Added boolean field in LK.ITEMS demo file.
0001236: Linkar Logs Database. Added End Time.
New column added with the petition execution's final date and time in the database. Useful for calculating execution times.
Date and Time in log are indicated according to local time of the server where the database is allocated. Previously, it was being converted to UTC time.
Linkar Manager
0000905: New button to download configuration files in Linkar Config.
0000967: Solved Kestrel log generation with serilog.
Logs were not generating.
0001099: Fixed bug on Linkar Manager / Linkar Config /Users. Autogenerate password button didn't work.
0001200: Master and EntryPoint Parameters forms.

Linkar Manager on all platforms and Linkar Server on Linux and MacOS platforms now use .NET 5.0
New Linkar DOCKER License
0000791: Linkar Suite can now run on Docker platforms.
Linkar SERVER
0000819: Bug fixed in the creation of the new statistics files.
When it is necessary to create new statistics files, if there are multiple requests at the same time, it could be the case that two or more threads detect that the statistics files do not exist and try to create them at the same time, causing an error that the file is being used by another process.
0000779: New LinkarServerConsole command (Windows/Linux/IOS)
Added new LinkarServerConsole application to run LinkarServer as a normal console process.
The program terminates by pressing Ctrl+X.
Added new parameter --ip to overwrite the ip specified in config.xml
0000751: Implementation of 3 retries of database connection
At the starting of a database session, up to 3 confirmation retries have been implemented with a delay of 1 second in each attempt.
The first attempt has no delay, but if it fails, wait 1 second and lkping is sent again, and so on up to three times.
0000750: Correct resizing of the data buffer size on reception.
In some occasions the reception was crashing because the EOT character was not found. This has been solved by correctly resizing the size of the data buffer in reception.
0000830, 0000860: New automatic license update service
Linkar Server makes backgroud calls to a Kosday service that checks the license data. If the license has been updated, the data is changed on the fly, without the need to stop Linkar Server.
A button has also been created in Linkar Manager/Configuration/Activation called "Check and update license".
0000832, 0000836, 0000889: Improvements in the opening and closing of database sessions.
Until now, database sessions were opened one at a time using the same thread. When the first one was opened, the second one was started and so on. Now one thread is used for each session opening so we gain processing speed in the EntryPoint opening. The speed of the opening will also depend on the CPU of the database.
The same happens in the closing process.
Linkar MANAGER
0000780: Linkar user passwords can now be displayed.
0000781, 0000782: Added new validations on deletion of Profiles or EntryPoints
- It is not allowed to delete a Profile if any of its EntryPoints is on.
- It is not allowed to delete an EntryPoint if it is turned on.
0000787: A new port has been created to receive https requests.
In this way http and https requests can coexist. The default port for https is 11202.
A new switch "Require SSL" has been added to force https requests.
0000804: LinkarManagerControl OPENBROWSER. Opening http or https
The LinkarManagerControl program with the OPENBROWSER option, always opened the web browser with the LinkarManager access url in http mode. Now, according to the configuration found in the Config.xml file, it will use http or https url.
0000784, 0000785, 0000823: New Management of password collection via web service
Every time LinkarServer has to open a line in the Database, if the "Get Passwords From Web Service" feature is enabled in the EntryPoint, before opening the line, the web service indicated in "Database Password URL" is consulted to obtain the password to be used.
The URLs for obtaining passwords, token requests and their parameters are stored encrypted.
Capture fields in Linkar Manager do not display data unless the show button is pressed.
0000854: Added new menu "Kestrel" in Linkar Manager/Linkar Logs
To view, download or delete the logs generated by the kestrel web server.
0000890: Bug Fixed in ResetCommonBlock of Linkar Manager
If there were no open sessions, Linkar Manager would wait forever for a response.

Now, when using the UPDATE or NEW methods in any of the XML or JSON formats, it is not necessary to remove tags from the Calculated dictionaries. They will not be used in the recording process because they are calculated data. No error will be launched.
0000789: Added UpdatePartial function
Modifies one or more attributes of one or more file records. Emulates databasic WRITEV statement
Linkar SCHEMAS
000731: Improved automatic generation of properties in Linkar Schemas

0000555: Fixed MVSP connection issues in D3 version 10
Revision 2.1.1 21 AUG 2020
WARNINGS (if you already have Linkar SERVER installed)
You must upgrade the MV Components.
Linkar SERVER
0000552: Fails Automatic Start with database in another machine
LinkarServer in Windows: restarting the computer was not stopping the LinkarServer service properly.
So if there were open EntryPoints with established connections to the Database, these connections were not closed properly.
This can cause that once the LinkarServer restarts, the EntryPoint could not reopen the connections correctly.
0000551: Database encoding. Fixed malfuncions
LinkarServer in Windows, having the Encoding of the profile configured as "Default", connects and works with most of the databases.
LinkarServer in Windows uses code page 1252 as the Default Encoding. However, Linkar Server in Linux uses code page 651001 (UTF8) as the Default Encoding. And Linux databases don't work well with this code page,
Therefore, in the Profile configuration, it is necessary to indicate the correct Encoding of the Database. In most Linux databases the code page is 437 or 850.
In some scenarios, LinkarServer did not make the correct conversions between the encoding of the LinkarServer application (Windows / Linux) and the Database. This could cause MV marks and/or accented characters not been sent or received correctly. This had different consequences :
oWhen opening an EntryPoint, the connection with the Database could not be established, because the MV marks were not arriving correctly.
oIn some cases, the MV marks were sent and received correctly, but there could be problems when interpreting some special characters (accents, ñ, ...)
oWhen opening an EntryPoint, the connection with the Database could not be established, because the MV marks were not arriving correctly.
oIn some cases, the MV marks were sent and received correctly, but there could be problems when interpreting some special characters (accents, ñ, ...)
