Each byte is an integer value + * in the range [0-255]. To be a Tcl value type, we need a way to encode each + * value in the value set as a Tcl string. The simplest encoding is to + * represent each byte value as the same codepoint value. A bytearray of N + * bytes is encoded into a Tcl string of N characters where the codepoint of + * each character is the value of corresponding byte. This approach creates a + * one-to-one map between all bytearray values and a subset of Tcl string + * values. + * + * When converting a Tcl string value to the bytearray internal rep, the + * question arises what to do with strings outside that subset? That is, + * those Tcl strings containing at least one codepoint greater than 255? The + * obviously correct answer is to raise an error! That string value does not + * represent any valid bytearray value. Full Stop. The setFromAnyProc + * signature has a completion code return value for just this reason, to + * reject invalid inputs. + * + * Unfortunately this was not the path taken by the authors of the original + * tclByteArrayType. They chose to accept all Tcl string values as acceptable + * string encodings of the bytearray values that result from masking away the + * high bits of any codepoint value at all. This meant that every bytearray + * value had multiple accepted string representations. + * + * The implications of this choice are truly ugly. When a Tcl value has a + * string representation, we are required to accept that as the true value. + * Bytearray values that possess a string representation cannot be processed + * as bytearrays because we cannot know which true value that bytearray + * represents. The consequence is that we drag around an internal rep that we + * cannot make any use of. This painful price is extracted at any point after + * a string rep happens to be generated for the value. This happens even when + * the troublesome codepoints outside the byte range never show up. This + * happens rather routinely in normal Tcl operations unless we burden the + * script writer with the cognitive burden of avoiding it. The price is also + * paid by callers of the C interface. The routine + * + * unsigned char *Tcl_GetByteArrayFromObj(objPtr, lenPtr) + * + * has a guarantee to always return a non-NULL value, but that value points to + * a byte sequence that cannot be used by the caller to process the Tcl value + * absent some sideband testing that objPtr is "pure". Tcl offers no public + * interface to perform this test, so callers either break encapsulation or + * are unavoidably buggy. Tcl has defined a public interface that cannot be + * used correctly. The Tcl source code itself suffers the same problem, and + * has been buggy, but progressively less so as more and more portions of the + * code have been retrofitted with the required "purity testing". The set of + * values able to pass the purity test can be increased via the introduction + * of a "canonical" flag marker, but the only way the broken interface itself + * can be discarded is to start over and define the Tcl_ObjType properly. + * Bytearrays should simply be usable as bytearrays without a kabuki dance of + * testing. + * + * The Tcl_ObjType "properByteArrayType" is (nearly) a correct implementation + * of bytearrays. Any Tcl value with the type properByteArrayType can have + * its bytearray value fetched and used with confidence that acting on that + * value is equivalent to acting on the true Tcl string value. This still + * implies a side testing burden -- past mistakes will not let us avoid that + * immediately, but it is at least a conventional test of type, and can be + * implemented entirely by examining the objPtr fields, with no need to query + * the intrep, as a canonical flag would require. + * + * Until Tcl_GetByteArrayFromObj() and Tcl_SetByteArrayLength() can be revised + * to admit the possibility of returning NULL when the true value is not a + * valid bytearray, we need a mechanism to retain compatibility with the + * deployed callers of the broken interface. That's what the retained + * "tclByteArrayType" provides. In those unusual circumstances where we + * convert an invalid bytearray value to a bytearray type, it is to this + * legacy type. Essentially any time this legacy type gets used, it's a + * signal of a bug being ignored. A TIP should be drafted to remove this + * connection to the broken past so that Tcl 9 will no longer have any trace + * of it.
