• Fixed an issue where additional c files were converted into scenarios, preventing the immediate execution of truclient scripts in BlazeMeter.

V.2.47

Converter

• Fixed issue where 99% edge case without unsupported functions listed. The issue was a function declaration with parameters defined in multiple lines were being marked as not converted, even though they were.

• Fixed issue with web_cleanup_cookie. There was an issue where each subsequent call to getCookieManager().clear() would return null and cause groovy errors. We now simply overwrite cookies with an empty array to avoid this issue.

• Fixed issues with web_reg_save_param_ex.

• 'Show all' button is now disabled when there is no filter applied.

• Removed KPI slider and renamed column to manual effort in script table.

• Added redirect from http to https when accessing the dashboard.

• Updated Google tracking and analytics tool on shift-left converter page.

V.2.44

Conversions

General

• Added support for custom functions with nested invocations in parameters. Custom functions that invoke c functions and custom functions or binary operations such as some_custom_function(5+another_func()).

• Added support to mutable parameters for custom functions. Now pointers in parameters are properly converted, and values are overwritten in the after-function invocation groovy.

QA/Process

• Started using batect to handle the local compilation of source code and to execute tests in order to get the same behavior in Unix and Windows systems.

V.2.43

Conversions

General

• Expanded custom functions to properly handle variable or parameter names in functions with the same variable name as the outer scope.

• Now generating a JSR223 script to back up variables and fix issues related to the previous implementation.

• Added logic to properly handle custom functions with short circuit logic or early return. Now we evaluate a returned variable before invoking function logic.

• Fixed issues for TruClient scripts; we are now properly handling unsupported actions that caused issues while generating the Selenium file.

V.2.42

Conversions

General

• Extended support for web_reg_save_param_ex; now it's properly handling requestUrl as a parameter. IgnoreRedirections is being ignored since behavior is applied by default to JMeter.

• Extended support for web_reg_save_param, now converting parameter Convert to encode/decode URL values.

• Support for basic custom functions logic:

  • CF: Invocation that has no return and no parameters.

  • CF: Invocation with return statement and no parameters.

  • CF: Invocation with immutable parameter.

V.2.41

Conversions

General

• Users can now be given access to this repo by creating a service account and sending them a credentials.json file. They can use docker login using the given file as a password.

• Created a document explaining how to reduce loadrunner script size, where we identify a few folders and files generated at runtime.

• Added support for conversion of lr_save_var.

• Refactored code used to process escaped characters to avoid code duplication and easier maintenance.

• Now preprocesses multiline string before running actual conversion to avoid unnecessary loops while parsing script.

• Modifications were made to database and dashboard stats calculation; now they use the same conversion percentage calculation in the dashboard as in the UI (using sentences).

• When there is a parsing failure due to a user error in the script, now shows a warning or indicator to the user.

• When the parser fails, now generates a log with an exception and stores it in summary.

V.2.40

Conversions

General

• Added logic to detect recursive calls and mark a function as not supported. Now all recursive invocations are marked as not supported. This is done due to logic from Taurus. In Taurus when an include-scenario is called, Taurus simply pastes the code of the scenario. In recursive functions this is an infinite loop and ends up crashing.

• Now checks if an empty scenario is invoked. If the scenario is empty, it is simply ignored and marked as supported.

• Added support for strncat.

• Added support for lr_advance_param; this implementation also includes changes to the way parameters are converted.

• Now ignores web_set_sockets_option SHUTDOWN_MODE. JMeter doesn't allow setting the shutdown mode for sockets.

• Unified frontend technologies to only use vue.js. This should not have an impact on UI, only some minor changes to aesthetics of the frontend.

• Now it is not necessary for the input script to include the [ExtraFiles] tag in the .usr file. This is missing in some scripts that are generated in older vugen versions.

• Added support for lr_decrypt; this uses the same implementation as lr_unmask.

V.2.39

Conversions

General

• Added implementation of lr_free_parameter.

• Improved lr_save_param_regexp handling of escaped quotes, and also fixed escaped quotes generating \ on variable declaration.

• Removed unnecessary jsr elements that were added to samplers when IGNORE_PREMATURE_SHUTDOWN was set. Now it is only added to http samplers.

• Fixed a particular issue when log was being added inside an else statement in a complex transaction. The log was added outside of the if statements, now they are added to the correct location.

V.2.38.1

Conversions

General

• Improved message provided to users to differentiate notification and critical messages(eg. lr_vuser_data_point will use new information message changes).

• Modified support of parallel controllers conversion. We now modify generated modified_requests.jmx to properly execute parallel executions.

• Fixed issue with web_reg_save_param_regexp, where the requestUrl parameter was not being converted properly. This is now being converted into a groovy script and regex is applied to all specified URLs.

• Added support to variable parameters in lr_think_time.

Developer Note
This is a re-release of version 2.38, we had to release a hotfix (with no code changes) due to a failure on deployment and a protected on-prem file.

V.2.38

Conversions

General

• Improved message provided to users to differentiate notification and critical messages(eg. lr_vuser_data_point will use new information message changes).

• Modified support of parallel controllers conversion. We now modify generated modified_requests.jmx to properly execute parallel executions.

• Fixed issue with web_reg_save_param_regexp, where the requestUrl parameter was not being converted properly. This is now being converted into a groovy script and regex is applied to all specified URLs.

• Added support to variable parameters in lr_think_time.

V.2.37

Converter

• Added support for custom delimiter definitions.

• Added support for conversions of lr_unmask.

• Added support for conversions of atof.

• web_cache_cleanup and web_cleanup_cookies are now being converted to groovy scripts, where before they simply disabled cookies/cache by removing managers.

• Added support for conversions of lr_save_param_regexp.

V.2.36

Converter

• Added support for conversions of lr_set_transaction_status.

• Added support for conversions of memset.

• Added support for conversions of lr_paramarr_random.

• Now ignores & operator when used in function parameter.

• Fixed issue when web_reg_save_param_regexp was used with regexp= inside parameter which was generating regex extractor with Regex= in final regex.

V.2.35

Converter

• Before, extrares were being converted into simple controllers. Extrares are now added as a postprocessor so that it applies regex extractors and any post-processing applied to the parent sampler.

• Correlation files (.cor) are now supported as a conversion. Currently, we support the conversion of boundary extractors, with no manipulation to the actual regex (eg. ignore case). If any manipulation is done, they will be handled as simple boundary extractors. The generated files are described within the readme of the conversion.

  • JMX - Converted correlations preloaded into a JMX so the user can easily start recording with the rules.

  • Template folder - The user can use this folder to import converted rules into an existing JMX project.

• Support was added for input files such as .usz and .cor without zipping.

• Fixed issue when transaction open/closure logic is complex, there is additional logic between open/close transactions (we convert these to groovy), and it has no parent transaction. Before they were added after all other transactions were closed, which was incorrect as requests and any other logins inside the transaction would also be added out of order. Now they are properly converted into the correct order.

QA

• Tested converted scripts and validated that they were properly executed in BlazeMeter.

V.2.34

Conversions

General

• Extended support and fixed an issue for web_reg_find.

  • Added logic to support body and headers when search field has value all.

  • Fixed issues where the template wasn't being converted to the correct value when creating a jsr223 assertion.

• Extended support to properly handle groovy transactions for lr_fail_trans_with_error.

• Fixed issue when web_concurrent_end was invoked without invoking start was being marked as not supported. They are now converted to a YAML comment and marked as supported in statistics.

• Extended support and fixes for array references and declaration:

  • Added support to the assignment of value at a specific position. (e.g. num[0] = rand() % 100)

  • Fixed references with array declaration when the index uses a variable (e.g var[i]= varx[i])

• Removed comments conversion.

  • Now uses cpp compiler to properly remove any user-defined comments. This was done to fix issues with comments invoked in parameters of functions. (e.g. web_url("url=https://www.blazemeter.com", // comment causes issues).

  • Comments were causing a huge section for the script. After removing the comment conversion logic, the issue was resolved.

• Reworked transaction logic to handle nested transactions, closing transactions at different levels and closing at different orders.

  • There were several scripts where the order of actions was being added in a different order than declared in the original script. This was due to improper handling of active transactions. Before we simply tracked currently open transactions, now we keep track of all open and closed transactions. Additionally, we generate groovy transactions when logic is not applicable in JMeter (such as closing transactions at different structure levels).

• Fixed issues where jr223 elements were being added in an incorrect request due to special cases like lr_exit, calling an action, etc.

• Fixed issues where strlen, lr_get_vuser_ip, and empty statements were being marked as unsupported. As well as some escape codes.

• Fixed issue with lr_xml_get_values that wasn't being converted for edge cases.

• Fixed web_reg_save_param.

• Added support to variables declared in default.cfg

• Fixed issue with headers not being converted on some occasions. Headers were ignored when the HEADERS attribute was declared. Also fixed issues where Enc-Type was not being properly handled and simply set header to raw value.

V.2.33

Conversions

General

• Converted strncpy to enable copy of n chars of a given string.

• Fixed conversions of already supported functions (sizeof, rand, web_get_int_property).

• Converted strtok enabling splitting a string with given delimiters.

• Fixed integer as condition clause. Some CBA scripts use as if condition the raw result of the function strncmp.

• Converted lr_fail_trans_with_error which caused all open transactions with LR_AUTO status to fail.

• Added proper initialize variables used by lr_get_attrib methods.

Maintenance

• Fixed cast conversion. Casts like (char *) strtok(str, del); were not marked as supported scenarios.

V.2.32

Conversions

General

• Converted lr_start_timer and lr_end_timer. Jrs223 was added in order to store the related variables and make the necessary calculations.

• Converted web_set_sockets_option MAX_CONNECTIONS_PER_HOST & LOAD_VERIFY_FILE options.

• General improvements:

  1. Simplified Taurus YML.

  2. LoadRunner constants are now parsed to JMeter.

  3. Added proper handling of __eval usage and quotes to avoid unnecessary quotes in labels and other JMeter properties.

  4. Added usage of getObject in assignment instead of just get to keep the type of the parameter.

  5. Discontinued use of args in groovy scripts which may cause unexpected behavior due to args splitting by spaces.

  6. Avoided double quote strings and use of single quote strings in groovy scripts to avoid groovy string interpolation failures.

  7. Set compile-cache to false for all JSR223 elements to properly support using JMeter variable references in them and avoid issues in iterations.

  8. Now avoiding missing jsr223 scripts when they are not directly associated with a request, and fixed issues of jsr223 scripts misplacement when using ifs.

V.2.31

Conversions

General

• #define, #ifndef, #endif are now marked as supported and #define with constant declaration was converted to a JMeter variable.

• Modified printf and fix sprintf to properly handle numeric and string parameters.

• Converted web_set_sockets_option INITIAL_AUTH option.

On-Premise

• You can now generate easily mappable statistics when running batch conversions by setting the -e flag.

V.2.3.0.

Conversions

General

• If Jenkins fails in the deployment or after smoke test is ran, all changes are rolled back to previous version.

• Added functional tests for HAR converter to validate stability of the feature. 

• Added support to the first RTE command, TE_connect, this includes functional tests. Currently RTE is not functional as this function isn't a request, more functions for RTE will be supported in future releases.

• Now, using CDN to route traffic to https. These changes should help reduce costs for the converter.

V.2.2.2.

Brain & Dashboard changes:

Improvements

• The On-Premise converter now supports converting HAR files (and all formats supported by https://converter.blazemeter.com/) in the batch conversion and through Webapp. Related BUG tickets  and Enhancements were requested by customers.
