Description

Visualization method and device for debugging business process
Technical Field
The present invention relates to the field of computer technologies, and in particular, to a visualization method and apparatus for debugging a business process.
Background
The service flow is a directed graph which meets the specific service scene and consists of a start node and a series of service function nodes, and comprises the transmission of data flow, and describes the transition of data or state of specific service from start to end. Other business processes are supported and called in the business processes, so that a complex business scene is conveniently split into a plurality of small business processes, and meanwhile, the business processes are also conveniently multiplexed.
Before service online, a local early test is often needed to be performed on the service flow to detect whether the service flow meets service requirements, whether data conversion accords with expectations, and the like. In this process, the debugging functionality provided by the business process debugging system is particularly important. The debugging function can support the user to track the execution process of the business process, check the data change before and after a certain node in the execution business process, help the user to quickly locate the problem when the test result does not accord with the expectation, and the like.
Typically, the execution of a business process is unidirectional, i.e., a thread executes a process. However, some business scenarios require parallel processing of a flow, then merging the results of the parallel processing, and then continuing to execute subsequent flows. In this case, the debugging of the multi-threaded flow is involved. Most of the current business process debugging systems support multi-thread debugging, when a plurality of threads execute nodes in parallel in the same business process, most of the debugging systems show the currently running threads in a level display mode in a thread stack area, and provide thread switching and variable display and modification functions based on the threads.
In the process of implementing the invention, the inventor finds that the existing business process debugging system has at least the following problems in the process of visualization: first, thread management is unclear. Specifically, when debugging is performed on multiple threads, all threads are displayed in a level in a thread stack area, and the calling relationship among the threads cannot be known conveniently. Second, when executing child flows in parallel based on multithreading, it is impossible to locate its parent flow. Specifically, after the process is started, a flowchart is opened to display the execution process of the process; when the sub-flow call node is executed, the flow chart of the called sub-flow is opened again so as to display the execution process of the sub-flow; and when the sub-flow call node is in the parallel mode, a plurality of identical sub-flow charts are opened at the same time. Furthermore, when the current debugging is suspended in a certain sub-flow, it cannot be determined which flow the sub-flow is called by, and great inconvenience is brought to the debugging work of the business flow.

Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It is noted that embodiments of the invention and features of the embodiments may be combined with each other without conflict.
Fig. 1 is a schematic flow diagram of a visualization method for business process debugging according to a first embodiment of the present invention. The method of embodiments of the present invention may be performed by a visualization device (alternatively referred to as a "debug GUI") for business process debugging. As shown in fig. 1, a visualization method for business process debugging according to an embodiment of the present invention includes:
Step S101, a main debugger is created in response to the triggering operation of a user, and the debugging configuration information of the service flow is sent to a debugging engine based on the main debugger, so that the debugging engine carries out service flow debugging according to the debugging configuration information.
Illustratively, the triggering operation of the user may be: the user selects a business process on the software interface and then clicks the "start debug" button. In response to the trigger operation by the user, execution of step S101 is started.
In step S101, after creating the master debugger, the debug GUI may send debug configuration information to the debug engine based on the master debugger. The debugging configuration information can include information such as business process identification, content of a process file, breakpoints set by a user, positions of some dependent files used in the process, and the like.
After receiving the debugging configuration information, the debugging engine can perform debugging initialization work according to the debugging configuration information. The debugging initialization is mainly used for establishing a debugging environment of the current debugging. After the debugging initialization operation is completed, the debugging engine prepares to execute the business process and feeds back a message to the debugging GUI in the process of executing the business process.
Step S102, receiving a message returned by the debugging engine in the process of debugging the business process.
The message may be a first message indicating that execution of the parallel node is started, a fourth message indicating that execution of the non-parallel node is started, or other messages returned by the debug engine. In a business process, there are parallel nodes (alternatively referred to as "parallel call sub-process nodes") and non-parallel nodes. Where parallel nodes refer to nodes executed by multiple threads, and non-parallel nodes refer to nodes executed by a single thread.
Step S103, after the message is determined to be the first message, a thread call tree is drawn and displayed in a first area on the page, and a plurality of sub-flowcharts nested in the same tag page are drawn and displayed in a second area on the page according to the identification of the parallel node and the information of a plurality of threads for executing the parallel node.
Wherein the first message is used for indicating that the parallel node starts to execute. In particular, when the debug engine executes to the parallel node, a first message may be sent to the debug GUI, where the first message includes information such as a flow identifier and a parallel node identifier. After the debug GUI receives the first message, a thread call tree can be drawn in a first area (or referred to as a "thread stack area") on the page, so that the call relationship between multiple threads in the process of debugging the business process is clearly represented in a tree structure. And the debugging GUI can draw and display a plurality of sub-flowcharts nested in the same tag page in a second area on the page according to the identification of the parallel node and the information of a plurality of threads for executing the parallel node. By nesting a plurality of sub-flowcharts corresponding to parallel nodes in the same tag page, the sub-flowcharts can be conveniently and quickly positioned to the parent process.
In the embodiment of the invention, the problems that thread management is unclear, a father process cannot be positioned when the multi-thread Cheng Zhihang sub-process exists in the prior art are solved through the steps, and the like, so that a developer can conveniently and rapidly debug the business process.
Fig. 2 is a partial flow diagram of a visualization method for business process debugging in accordance with a second embodiment of the present invention. As shown in fig. 2, a visualization method for business process debugging according to an embodiment of the present invention includes:
step S201, a main debugger is created in response to the triggering operation of a user, and the debugging configuration information of the business process is sent to a debugging engine based on the main debugger, so that the debugging engine carries out the business process debugging according to the debugging configuration information.
Illustratively, the triggering operation of the user may be: the user selects a business process on the software interface and then clicks the "start debug" button. In response to the trigger operation by the user, execution of step S201 is started.
In step S201, after creating the master debugger, the debug GUI may send debug configuration information to the debug engine based on the master debugger. The debugging configuration information can include information such as business process identification, content of a process file, breakpoints set by a user, positions of some dependent files used in the process, and the like.
After receiving the debugging configuration information, the debugging engine can perform debugging initialization work according to the debugging configuration information. The debugging initialization is mainly used for establishing a debugging environment of the current debugging. After the debugging initialization operation is completed, the debugging engine prepares to execute the business process and feeds back a message to the debugging GUI in the process of executing the business process.
Wherein the message may include: a message indicating that execution of the flow is to begin, a first message indicating that execution of the parallel node is to begin, a fourth message indicating that execution of the non-parallel node is to begin, and other messages returned by the debug engine. For example, after the debug engine completes the debug initialization, it sends a "start execution flow" message to the debug GUI. After receiving the message of "start executing the flow", the debug GUI may find a flow file according to the flow identifier carried by the message, then create a tag page according to the second area (or referred to as "flow chart display area") of the flow file on the page, and display a flow chart (or referred to as main flow chart) corresponding to the flow file in the tag page.
Step S202, receiving a message returned by the debugging engine in the process of debugging the business process.
Step 203, when the message is a fourth message, determining a corresponding graph of the non-parallel node in the flow chart according to the flow identifier and the non-parallel node identifier carried by the fourth message, and then rendering the corresponding graph into a to-be-executed state.
In a business process, there are parallel nodes (alternatively referred to as "parallel call sub-process nodes") and non-parallel nodes. Where parallel nodes refer to nodes executed by multiple threads, and non-parallel nodes refer to nodes executed by a single thread.
In one example, the debug engine, upon execution to a common node (i.e. non-parallel node), may send a fourth message to the debug GUI indicating that execution of the non-parallel node is to begin, the fourth message containing the flow identification and the node identification. After the debug GUI receives the fourth message, the flow chart where the node is located can be determined according to the flow mark carried by the fourth message, then the corresponding graph of the node in the flow chart is determined according to the node mark, and then the corresponding graph is rendered into a to-be-executed state. For example, the color of the corresponding graphic may be rendered into a color that characterizes the state to be executed.
And step S204, when the message is a first message, creating a label page named by the parallel node in a second area of the page according to the identification of the parallel node carried by the first message. After step S204, step S205 to step S208 may be performed.
In one example, the debug engine, upon execution to one of the parallel nodes, may send a first message to the debug GUI indicating that execution of the parallel node is to begin, the first message containing a flow identification and a node identification. After the debug GUI receives the first message, a tab page named by the parallel node may be created at a position (e.g. the right side of the tab page where the main flow is located) in the second area of the page according to the node identifier carried by the first message, so as to display execution procedures of all sub-flows under the parallel node.
Step S205, receiving a second message returned by the debugging engine.
In one example, the debug engine may determine the number of threads to execute the parallel node based on the configuration information for the parallel node, then create and launch the threads, and send a second message to the debug GUI. Wherein the second message is used to indicate that a plurality of threads for executing the parallel node are started. The second message may include information such as a flow identification, a name of the new thread, an identification of a sub-flow to be executed by the new thread, and the like. After that, the debug GUI receives the second message.
In the implementation, after a thread for executing the parallel node is started, the debug engine may send a message for indicating that the thread is started to the debug GUI, that is, send starting messages of each thread in sequence; alternatively, the debug engine may send a message to the debug GUI indicating that all threads executing the parallel node are started after all threads executing the parallel node are started.
Step S206, creating a plurality of sub-debuggers of the current debugger according to the second message, and adding the information of the plurality of sub-debuggers to a sub-debugger list of the current debugger.
In one example, the debug GUI may create multiple sub-debuggers of the current debugger from the second message and save the information of the thread carried by the second message to each sub-debugger, and the debug GUI may add the information of each newly created sub-debugger to the sub-debugger list of the currently located debugger. The plurality of sub-debuggers are in one-to-one correspondence with a plurality of threads for executing the parallel nodes. In particular, the current debugger may be a main debugger or a sub-debugger. The main debugger and the sub debugger are both used for communicating with a debug engine.
Step S207, drawing a thread call tree in a first area on a page according to a sub-debugger list of the current debugger and displaying the thread call tree.
In the embodiment of the invention, because the structure of the current debugger reflects the calling relation between the father thread and the multiple threads (namely, the child threads) executing the parallel node, the thread calling tree can be drawn and displayed in the first area on the page according to the child debugger list of the current debugger.
And step S208, drawing and displaying a plurality of sub-flowcharts in the tag page according to the information, carried by the second message, of the plurality of threads for executing the parallel nodes.
In one example, the debug GUI may find a previously created tab page (e.g. tab page) named for the parallel node from the node identification carried by the second message, create a tab page in the tab page named for each thread executing the parallel node, and draw and display a sub-flowchart to be executed by the thread in the tab page named for each thread.
In the embodiment of the invention, the problems that the thread management is unclear, the father process can not be positioned when the multi-line Cheng Zhihang sub-process exists in the existing visualization method for debugging the business process can be solved through the steps, and the like, so that a developer can conveniently and rapidly debug the business process.
Fig. 3 is a flow diagram of a visualization method for business process debugging in a third embodiment of the present invention. The method of embodiments of the present invention may be performed jointly by a debug GUI (debug visualization component, also referred to as a "means for business process debugging") and a debug engine. As shown in fig. 3, a visualization method for business process debugging according to an embodiment of the present invention includes:
Step S301, the debugging GUI creates a main debugger and sends debugging configuration information of the business process to a debugging engine.
In this step, after creating the master debugger, the debug GUI may send debug configuration information to the debug engine based on the master debugger. The debugging configuration information can include information such as business process identification, content of a process file, breakpoints set by a user, positions of some dependent files used in the process, and the like.
Step S302, the debugging engine performs debugging initialization.
After receiving the debugging configuration information, the debugging engine can perform debugging initialization work according to the debugging configuration information. The debugging initialization is mainly used for establishing a debugging environment of the current debugging.
After the debugging initialization operation is completed, the debugging engine prepares to execute the business process and feeds back a message to the debugging GUI in the process of executing the business process. For example, after the debug engine completes the debug initialization, it sends a "start execution flow" message to the debug GUI. After receiving the message of "start executing the flow", the debug GUI may find a flow file according to the flow identifier carried by the message, then create a tag page according to the second area (or referred to as "flow chart display area") of the flow file on the page, and display a flow chart (or referred to as main flow chart) corresponding to the flow file in the tag page.
Step S303, the debugging engine sends a fourth message to the debugging GUI.
Wherein the fourth message is used to indicate that execution of the non-parallel node is to begin. In one example, the debug engine, when executing to a common node (i.e. non-parallel node), may send a fourth message to the debug GUI, which contains the flow identification and the node identification.
Step S304, the debugging GUI determines the corresponding graph of the non-parallel node in the affiliated flow chart according to the flow mark and the non-parallel node mark carried by the fourth message, and then the corresponding graph is rendered into a to-be-executed state.
In this step, after the debug GUI receives the fourth message, the flowchart in which the node is located may be determined according to the flow identifier carried by the fourth message, then the corresponding graph of the node in the flowchart to which the node belongs is determined according to the node identifier, and then the corresponding graph is rendered into the to-be-executed state. For example, the color of the corresponding graphic may be rendered into a color that characterizes the state to be executed.
Step S305, the debug engine sends a fifth message to the debug GUI.
Wherein the fifth message is used for indicating that the non-parallel node execution is finished. In one example, the debug engine may send a fifth message to the debug GUI when a common node is executed, the fifth message may contain information such as flow identification, node execution results, and the like. The node execution result may be indication information of execution success or execution failure.
Step S306, the debugging GUI determines the corresponding graph of the non-parallel node in the affiliated flow chart according to the flow mark and the non-parallel node mark carried by the fifth message, and then renders the corresponding graph into an execution completion state.
Wherein the execution completion status includes: an execution success state and an execution failure state. In this step, the debug GUI may determine, according to the flow identifier carried by the fifth message, a flow chart in which the node is located, then determine, according to the node identifier, a corresponding graph of the node in the flow chart to which the node belongs, and render, according to the result of executing the node, the corresponding graph into an execution success state or an execution failure state. For example, the debug GUI may render the corresponding graphics into a color for characterizing execution success or a color for characterizing execution failure based on the results of node execution. In addition, the debugging GUI can also find the identification of the last node according to the node execution linked list maintained internally, find the corresponding graph of the last node in the flow chart according to the identification of the last node, and render the directed line segment between the graphs corresponding to the two nodes in the flow chart into a color for representing successful execution or a color for representing failed execution.
Step S307, the debug engine sends a first message to the debug GUI.
Wherein the first message is used to indicate that execution of the parallel node is to begin. In this step, the debug engine, when executing to a parallel node, may send a first message to the debug GUI, the first message containing a flow identification and a node identification.
Step S308, the debugging GUI creates a label page named by the parallel node in a second area of the page according to the identification of the parallel node carried by the first message.
In this step, after the debug GUI receives the first message, a tab page named by the parallel node may be created at a position (e.g. the right of the tab page where the main flow is located) in the second area of the page according to the node identifier carried by the first message, so as to display execution procedures of all sub-flows under the parallel node.
Step S309, the debugging engine sends a second message to the debugging GUI.
Wherein the second message is used to indicate that a plurality of threads for executing the parallel node are started. In this step, the debug engine may determine the number of threads for executing the parallel node based on the configuration information of the parallel node, then create and start the threads, and send a second message to the debug GUI. Wherein the second message is used to indicate that a plurality of threads for executing the parallel node are started. The second message may include information such as a flow identification, a name of the new thread, an identification of a sub-flow to be executed by the new thread, and the like. After that, the debug GUI receives the second message.
Step S310, the debugging GUI creates a plurality of sub-debuggers of the current debugger according to the second message, adds the information of the plurality of sub-debuggers to a sub-debugger list of the current debugger, draws a thread call tree and displays the thread call tree in a first area on a page according to the sub-debugger list of the current debugger, and draws a plurality of sub-flowcharts and displays the sub-flowcharts in the tag page according to the information of a plurality of threads for executing the parallel node carried by the second message.
The plurality of sub-debuggers are in one-to-one correspondence with a plurality of threads for executing the parallel nodes. In particular, the current debugger may be a main debugger or a sub-debugger. The main debugger and the sub debugger are both used for communicating with a debug engine.
Step S311, the debugging engine sends a third message to the debugging GUI.
Wherein the third message is used for indicating that the parallel node execution is finished.
Step S312, the debug GUI closes the plurality of subdebuggers according to the third message, deletes the information of the plurality of subdebuggers from the subdebugger list of the current debugger, and updates the thread call tree and the plurality of sub-flowcharts nested in the same tag page.
In the embodiment of the invention, the problems that the thread management is unclear, the father process can not be positioned when the multi-line Cheng Zhihang sub-process exists in the existing visualization method for debugging the business process can be solved through the steps, and the like, so that a developer can conveniently and rapidly debug the business process.
Fig. 4a to 4e are schematic diagrams of a visual interface in a process of debugging a business process according to a third embodiment of the present invention. The changes in the visual interface during the business process debugging process are described below in connection with fig. 4 a-4 e.
FIG. 4a shows a business flow diagram in this example, including a start node, a data conversion node, a parallel sub-flow call node (i.e., a "parallel node"), and an end node.
The debug engine sends a first message to the debug GUI when executing to the parallel sub-flow call node. The debug GUI refreshes the page according to the first message, the refresh result is shown in FIG. 4 b. Specifically, the debugging GUI may create a tab page named by the parallel node on the right side of the tab page where the main flow is located according to the node identifier carried by the first message, so as to display execution processes of all sub-flows under the parallel node.
Next, the debug engine determines the number of threads for executing the parallel node based on the configuration information of the parallel node, then creates and starts the threads, and sends a second message to the debug GUI. The debug GUI refreshes the page according to the second message, and the refreshing result is shown in FIG. 4 c. Specifically, the debug GUI draws and displays a thread call tree in a first region (i.e. thread stack region) on a page, and draws and displays multiple sub-flowcharts nested in the same tab page in a second region on the page.
Then, when the parallel node execution ends, the debug engine sends a message to the debug GUI indicating that the parallel node execution ends. The debug GUI refreshes the page according to the message, with the refresh result shown in fig. 4 d. Specifically, the debug GUI updates the thread call tree in the first region of the page and updates the flow diagram in the second region of the page.
Next, when the execution of the flow ends, the debug engine sends a message to the debug GUI indicating the end of the execution of the flow. The debug GUI refreshes the page according to the message, with the refresh result shown in fig. 4 e.
Fig. 5 is a schematic diagram of main modules of a visualization apparatus for business process debugging according to a fourth embodiment of the present invention. As shown in fig. 5, a visualization device 500 for business process debugging according to an embodiment of the present invention includes: a creation module 501, a receiving module 502, and a drawing module 503.
The creating module 501 is configured to create a master debugger in response to a triggering operation of a user, and send debugging configuration information of a service flow to a debugging engine based on the master debugger, so that the debugging engine performs service flow debugging according to the debugging configuration information.
Illustratively, the triggering operation of the user may be: the user selects a business process on the software interface and then clicks the "start debug" button. In response to the trigger operation by the user, execution of step S101 is started.
In one example, after creating the master debugger, creation module 501 may send debug configuration information to the debug engine based on the master debugger. The debugging configuration information can include information such as business process identification, content of a process file, breakpoints set by a user, positions of some dependent files used in the process, and the like. After receiving the debugging configuration information, the debugging engine can perform debugging initialization work according to the debugging configuration information. The debugging initialization is mainly used for establishing a debugging environment of the current debugging. After the debug initialization process is complete, the debug engine prepares to execute the business process and feeds back messages to the visualization device (or "debug GUI") for the debugging of the business process during execution of the business process.
And the receiving module 502 is configured to receive a message returned by the debug engine in a process of performing service flow debugging.
Illustratively, the message received by the receiving module 502 may be a first message for indicating that execution of the parallel node is started, a fourth message for indicating that execution of the non-parallel node is started, or other messages returned by the debug engine. In a business process, there are parallel nodes (alternatively referred to as "parallel call sub-process nodes") and non-parallel nodes. Where parallel nodes refer to nodes executed by multiple threads, and non-parallel nodes refer to nodes executed by a single thread.
A drawing module 503, configured to draw and display a thread call tree in a first area on a page after determining that the message is a first message, and draw and display a plurality of sub-flowcharts nested in the same tag page in a second area on the page according to the identification of the parallel node and information of a plurality of threads for executing the parallel node; wherein the first message is used for indicating that the parallel node starts to execute.
Wherein the first message is used for indicating that the parallel node starts to execute. In particular, when the debug engine executes to the parallel node, a first message may be sent to the debug GUI, where the first message includes information such as a flow identifier and a parallel node identifier. After the debug GUI receives the first message, the thread call tree may be drawn by the drawing module 503 in a first area (or referred to as a "thread stack area") on the page, so that the call relationship between the multiple threads in the process of debugging the service flow is clearly represented in a tree structure. And, the drawing module 503 may draw and display multiple sub-flowcharts nested in the same tag page in the second area on the page according to the identification of the parallel node and the information of the multiple threads for executing the parallel node. By nesting a plurality of sub-flowcharts corresponding to parallel nodes in the same tag page, the sub-flowcharts can be conveniently and quickly positioned to the parent process.
In one alternative example, the drawing module 503 draws a thread call tree at a first region on a page and displaying may include: after receiving a second message returned by the debug engine, creating a plurality of sub-debuggers of the current debugger according to the second message, and adding information of the plurality of sub-debuggers into a sub-debugger list of the current debugger; the second message is used for indicating that a plurality of threads for executing the parallel node are started, and the plurality of sub debuggers are in one-to-one correspondence with the plurality of threads for executing the parallel node; then, the thread call tree is drawn and displayed in a first area on the page according to the sub-debugger list of the current debugger.
In an alternative example, the drawing module 503 draws, in a second area on the page, a plurality of sub-flowcharts nested in the same tag page and displays the sub-flowcharts including: the drawing module 503 creates a label page named by the parallel node in a second area of the page according to the identifier of the parallel node carried by the first message, and then draws and displays a plurality of sub-flowcharts in the label page according to the information of a plurality of threads for executing the parallel node carried by the second message.
In the embodiment of the invention, the problems that thread management is unclear, a father process cannot be positioned when the multi-thread Cheng Zhihang sub-process exists in the prior art are solved by the device, and the like, so that a developer can conveniently and rapidly debug the business process.

As shown in fig. 6, a visualization system 600 for business process debugging according to an embodiment of the present invention includes: debug GUI601, debug engine 602.
The debug GUI601 is configured to create a master debugger in response to a triggering operation of a user, and send debug configuration information of a service flow to a debug engine based on the master debugger, so that the debug engine performs service flow debugging according to the debug configuration information; the debug GUI601 is further configured to receive a message returned by the debug engine during a process of performing a business process debugging; the debug GUI601 is further configured to draw and display a thread call tree in a first area on a page after determining that the message is a first message, and draw and display a plurality of sub-flowcharts nested in the same tag page in a second area on the page according to the identification of the parallel node and information of a plurality of threads for executing the parallel node; wherein the first message is used for indicating that the parallel node starts to execute.
The debug engine 602 is configured to perform a debug initialization operation according to the debug configuration information, execute a service flow after completing the debug initialization operation, and feed back a message to the debug GUI during execution of the service flow. Wherein the message may include: a message indicating that execution of the flow is to begin, a first message indicating that execution of the parallel node is to begin, a fourth message indicating that execution of the non-parallel node is to begin, and other messages returned by the debug engine. For example, after the debug engine completes the debug initialization, it sends a "start execution flow" message to the debug GUI. After receiving the message of "start executing the flow", the debug GUI may find a flow file according to the flow identifier carried by the message, then create a tag page according to the second area (or referred to as "flow chart display area") of the flow file on the page, and display a flow chart (or referred to as main flow chart) corresponding to the flow file in the tag page.
In the embodiment of the invention, the problems that thread management is unclear, a father process cannot be positioned when the multi-thread Cheng Zhihang sub-process exists in the prior art are solved through the system, and the like, so that a developer can conveniently and rapidly debug the business process.
