* | | * generic/tclZlib.c (Tcl_ZlibStreamGet): [Bug 3081008]: Ensure thatdkf2010-10-191-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | when a bytearray gets its internals entangled with zlib for more than a passing moment, that bytearray will never be shimmered away. This increases the amount of copying but is simple to get right, which is a reasonable trade-off. * generic/tclStringObj.c (Tcl_AppendObjToObj): Added some special cases so that most of the time when you build up a bytearray by appending, it actually ends up being a bytearray rather than shimmering back and forth to string. * tests/http11.test (check_crc): Use a simpler way to express the functionality of this procedure.

Convert "len" argument to signed int which any value already vetted for overflow issues will fit into. * generic/tclStringObj.c: Update caller; standardize panic msg. * generic/tclBinary.c (UpdateStringOfByteArray): Add panic when the generated string representation would grow beyond Tcl's size limits.

| | | | | | | | | | | | | | | | | | * generic/tclStringObj.c (Tcl_AppendObjToObj): an append of a byte array to another into an efficent operation. The problem was the (lack of) a proper growth management strategy for the byte array.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | patterns between Unicode and UTF string reps. Most notably the call: objPtr = Tcl_NewUnicodeObj(...,0); followed by a loop of calls: Tcl_AppendUnicodeToObj(objPtr, u, n); will now grow and append to the Unicode representation. Before this commit, the sequence would convert each append to UTF and perform the append to the UTF rep. This is puzzling and likely a bug. The performance of [string map] is significantly improved by this change (according to the MAP collection of benchmarks in tclbench). Just in case there was some wisdom in the old ways that I missed, I left in the ability to restore the old patterns with a #define COMPAT 1 at the top of the file.

| | | | | | | | | | | | | | | | | | | | | | | | has parallel structure with GrowUnicodeBuffer(). The revision permits allocation attempts to continue all the way up to failure, with no gap. It also directly manipulates the String and Tcl_Obj internals instead of inefficiently operating via Tcl_*SetObjLength() with all of its extra protections and underdocumented special cases.

| | | | | | | | | | | | | | | | | | | | | | | | array in a non-extended String struct to one Tcl_UniChar, meant to hold the terminating NUL character. Non-empty unicode strings are then stored by extending the String struct by stringPtr->maxChars additional slots in that array with sizeof(Tcl_UniChar) bytes per slot. This revision makes the allocation macros much simpler.
