LE modification for fork thread behaviour

There are multiple instances in the the core python implementation and in pypi packages where a thread calls fork and the child process tries to create a thread using pthread_create but results in an error. This error is due to the LE design imple...

Remove restriction on MVS files being closed when a thread ends

Knowledge Center documents the restriction that "All MVS files opened from a given thread and still open when the thread is terminated are closed automatically by the library during thread termination." (https://www.ibm.com/support/knowledgecenter...

Allow disposition to be specified on fopen

DISP=SHR cannot be set when fopening a file in write mode. In read mode it defaults to DISP=SHR. If the file is a PDS(E) member, this locks out the whole PDS(E) so that no-one can browse the other members. If you use a DD Card, then you can specif...

Search path for DLLs in Executable

Linux has a mechanism to have a default search path embedded in an executable when it tries to load a shared library, equivalent to DLL's on z/OS, called rpath. This path takes precedence over some default search paths such as system search paths ...

Provide an option to prevent RPTSTG(ON) from internally resetting the initial stack size

When RPTSTG(ON) option is set, LE resets the initial stack size to 1MB for 64-bit applications. This is fine for code in which LE automatically expands the stack when needed, however for generated code (as in JavaScript code from Node.js) in which...
