Schorr <aschorr@telemetry-investments.com> + * rwarray.c: Add new functions writeall and readall to implement + persistent state. + (write_backend): New helper function containing most of the logic + from do_writea. Note that we do not need to check nargs < 2 because + gawk will issue a fatal error if a function is called with fewer + than min_required_args. Clean up some minor issues with error + handling. + (do_writea): Grab the array argument and use write_backend to + do the rest of the work. + (do_writeall): Lookup SYMTAB and invoke write_backend. + (free_value): New function to free memory for data we end up ignoring + because the variables exist already. + (do_poke): Attempt to create variables that don't exist already or + are undefined. + (regular_array_handle): Wrapper around create_array. + (global_array_handle): Call create_array unless the variable exists + already and is an array with zero elements. + (read_global): New function used by readall to load global variables + from a file. + (read_one): New function to read a single array from a file. + (read_backend): New helper function containing most of the logic + from do_reada. Remove the superfluous nargs check. Read the file + prologue and then call read_global or read_one as appropriate to load + the data. + (do_reada): Grab the array argument and call read_backend with + read_one to load the data. + (do_readall): Call read_backend with read_global to load the data. + (read_array): Call read_elem with additional arg regular_array_handle. + (read_elem): Add a function argument controlling array creation to + pass down to read_value. + (read_value): Add a function argument to call for array creation + instead of calling create_array directly, since we may need to use + an existing array when populating global arrays in readall. + (func_table): Add writeall and readall. + * rwarray.3am: Document new functions writeall and readall. + +2021-12-08 Andrew J. Schorr <aschorr@telemetry-investments.com> + * testext.c (test_array_create): New function to create an array by name that enables testing whether an undefined variable can be converted by the API into an array. |
