Isomery program interaction method based on filename under Windows systems
Technical field
The invention belongs to the isomery program interaction method and technology field under Windows systems, and in particular to a kind of Windows Read/write conflict is avoided under system, ensures the isomery program interaction method based on filename that interaction is correctly carried out.
Background technology
Isomery program refers to different executable programs, such as executable program separate under Windows systems, i.e., mutual Independent EXE files.Function call inside program is not isomery program.Emulated in aerodynamics or aircraft overall performance In, user usually needs modification existing model structure, parameter, or the model that increase is new, to reflect under different situations System running state, therefore it is required that corresponding simulation software has the interaction capabilities with other isomery programs.
Read/write conflict fingering journey or program reading-white-writing data（Memory headroom）Caused logic conflict.Computer body Read/write conflict defined in architecture mainly includes write after write conflict, writeafterread conflict, read-after-write conflict and read after read conflict. Windows systems are stricter to file read-write control ratio, and generally program P1 opens file, another before being not turned off Individual program P2 can not open this document, and this document is read and write either P2 or read-write operation.
Isomery program, hereinafter abbreviated as P1, P2, conventional exchange method have following 4 kinds：
1) client/server（C/S）Pattern
P1 and P2 is interacted by way of transit server, as shown in Figure 1.Wherein P1, P2 represent two respectively Client.If P1 needs to send an information to P2, then need to complete by following three step：
Step 1：P1 connection servers, send information to server, and server is received and stored；P1 polls P2 whether into Work(obtains the information.
Step 2：Whether P2 connection servers, polling server corresponding information reach, and are obtained if information reaches corresponding Information.After obtaining successfully, server is notified, and disconnect the connection with server.
Step 3：After server waits P2 to obtain information success, respective markers positions is set, P1 polls confirmation send into Work(, disconnect the connection with server.
2) direct communication pattern（TCP/IP etc.）
Direct communication pattern has only been the absence of the transfer of independent third-party server compared with C/S model.P1, P2 are straight Interconnection is connect to interact as shown in Fig. 2 i.e. P1, P2 are respectively server and client side.Assuming that P2 needs to send a letter Cease to P1, then need following three step：
Step 1：P2 inquires about P1 server address, connects and sends information to P1.
Step 2：P1 receive informations simultaneously confirm.
Step 3：P2 receives confirmation message and disconnected.
3) memory module is shared
Shared memory module refers to P1（Or P2）Plot location space, P2 are opened up in internal memory（Or P1）Quote same Address space.
4) shared file pattern
Shared file pattern refers to by reading and writing of files to interact.Assuming that P1 needs to send an information to P2, then need Want following two steps：
Step 1：P1 opens file A, writes information to file A, closes file A；
Step 2：P2 opens file A, reads information, closes file A.
But above-mentioned isomery program interaction method is all present outside suitable deficiency.Customer end/server mode needs Independent third-party server, for common application program, such condition is typically invalid for this.Direct communication pattern Need to know the IP address of other side, be frequently connected and disconnected from connecting, and corresponding TCP/IP message transceiver module adds program The complexity of itself.The problem of needing program to handle read/write conflict in itself all be present in shared memory module and shared file pattern.

Compared with conventional isomery program interaction method, shown in the effect such as table 1 of the exchange method based on filename contrasts. As seen from Table 1, read/write conflict can be avoided using the exchange method based on filename, ensure the correctness of isomery program interaction compared with To be obvious.
The success rate of the isomery program interaction method of table 1
Because CFD1, MAP2 are by Fortran language developments, customer end/server mode and direct communication enough could not be realized Server and TCP/IP communication module required for pattern, so the success rate of interaction is 0.Shared memory module and shared file The reason for pattern fails is that read/write conflict causes program operation exception to exit.Shared memory module is related to the operation of memory address, Implement more complicated.
Because isomery program is by filename exchange information, as long as so other programs can explain the file of given rule Name, it is possible to read corresponding information.For example, for embodiment 1, interface program can be developed with Python, can also Developed with C++, C#, Java etc..So as to which the degree of coupling between isomery program reduces.
