The intent is + * to allow arbitrary binary data to pass through Tcl as a Tcl value + * without loss or damage. Such values are useful for things like + * encoded strings or Tk images to name just two. + * + * It's strange to have two Tcl_ObjTypes in place for this task when + * one would do, so a bit of detail and history how we got to this point + * and where we might go from here. + * + * A bytearray is an ordered sequence of bytes. 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. Prescribing a + * migration path will be the key element of that work. The internal + * changes now in place are the limit of what can be done short of + * interface repair.
