(JL) ----------------- Released 7.5, 4/21/96 ----------------------- + +5/1/96 (bug fix) "file tail ~" did not correctly return the tail +portion of the user's home directory. (SS) + +5/1/96 (bug fix) Fixed bug in TclGetEnv where it didn't lookup environment +variables correctly: could confuse "H" and "HOME", for example. (JO) + +5/1/96 (bug fix) Changed to install tclConfig.sh under "make install-binaries", +not "make install-libraries". (JO) + +5/2/96 (bug fix) Changed pkg_mkIndex not to attempt to "load" a file unless +it has the standard shared library extension. On SunOS, attempts to load +Tcl scripts cause the whole application to be aborted (there's no way to +get the error back into Tcl). (JO) + +5/7/96 (bug fix) Moved initScript in tclUnixInit.c to writable memory to +avoid potential core dumps. (JO) + +5/7/96 (bug fix) Auto_reset procedure was removing procedure from init.tcl, +such as pkg_mkIndex. (JO) + +5/7/96 (bug fix) Fixed cast on socket address resolution code that +would cause a failure to connect on Dec Alphas. (JL) + +5/7/96 (bug fix) Added "time", "subst" and "fileevent" commands to set of +commands available in a safe interpreter. (JL) + +5/13/96 (bug fix) Preventing OS level handles for stdin, stdout and stderr +from being implicitly closed when the last reference to the standard +channel containing that handle is discarded when an interpreter is deleted. +Explicitly closing standard channels by using "close" still works. (JL) + +5/21/96 (bug fix) Do not create channels for stdin, stdout and stderr on +Unix if the devices are closed. This prevents a duplicate channel name +panic later on when the fd is used to open a channel and the channel is +registered in an interpreter. (JL) + +5/23/96 (bug fix) Fixed bug that prevented the use of standard channels in +interpreters created after the last interpreter was destroyed. In the sequence + + interp = Tcl_CreateInterp(); + Tcl_DeleteInterp(interp); + interp = Tcl_CreateInterp(); + +channels for stdio would not be available in the second interpreter. (JL) + +5/23/96 (bug fix) Fixed bug that allowed Tcl_MakeFileChannel to create new +channels with Tcl_Files in them that are already used by another channel. +This would cause core dumps when the Tcl_Files were being freed twice. (JL) + +5/23/96 (bug fix) Fixed a logical timing bug that caused a standard channel +to be removed from the standard channel table too early when the channel +was being closed. If the channel was being flushed asynchronously, it could +get recreated before being actually destroyed, and the recreated channel +would contain the same Tcl_File as the one being closed, leading to +dangling pointers and core dumps. (JL) + +5/27/96 (bug fix) Fixed a bug in Tcl_GetChannelOption which caused it to +always return a list of one element, a list of the settings, for +-translation and -eofchar options. Now correctly returns the value +described by the documentation (Mark Diekhans found this, thanks!). (JL) + +5/30/96 (bug fix) Fixed a couple of syntax errors in io.test. (JL) + +5/30/96 (bug fix) If a fileevent scripts gets an error, delete it before +causing a background error. This is to allow the error handler to reinstall +the fileevent and to prevent infinite loops if the event loop is reentered +in the error handler. (JL) + +5/31/96 (bug fix) Channels now will get properly flushed on exit. (JL) + +6/5/96 (bug fix) Changed Tcl_Ckalloc, Tcl_Ckfree, and Tcl_Ckrealloc to +Tcl_Alloc, Tcl_Free, and Tcl_Realloc. Added documentation for these +routines now that they are officially supported. Extension writers +should use these routines instead of free() and malloc(). (SS) + +6/10/96 (bug fix) Changes the Tcl close command so that it no longer +waits on nonblocking pipes for the piped processes to exit; instead it +reaps them in the background. (JL) + +6/11/96 (bug fix) Increased the length of the listen queue for server +sockets on Unix from 5 to 100. Some OSes will disregard this and reset it +to 5, but we should try to get as long a queue as we can, for performance +reasons. (JL) + +6/11/96 (bug fix) Fixed windows sockets bug that caused a cascade of events +if the fileevent script read less than was available. Now reading less than +is available does not cause a flood of Tcl events. (JL, SS) + +6/11/96 (bug fix) Fixed bug in background flushing on closed channels that +would prevent the last buffer from getting flushed. (JL) + +6/13/96 (bug fix) Fixed bug in Windows sockets that caused a core dump if +a DLL linked with tcl.dll and referred to e.g. ntohs() without opening a +Tcl socket. The problem was that the indirection table was not being +initialized. (JL) + +6/13/96 (bug fix) Fixed OS level resource leak that would occur when a +Tcl channel was still registered in some interpreter when the process +exits. Previously the channel was not being closed and the OS level handles +were not being released; the output was being flushed but the device was +not being closed. Now the device is properly closed. This was only a +problem on Win3.1 and MacOS. (JL, SS) + +6/28/96 (bug fix) Fixed bug where transient errors were leaving an error +code around, so that it would erroneously get reported later. This bug was +exercised intermittently by closing a channel to a file on a very loaded +NFS server, or to a socket whose other end blocked. (JL, BW) + +7/3/96 (bug fix) Fileevents declared in an interpreter are now deleted +when the channel is closed in that interpreter. Before this fix, the +fileevent would hang around until the channel is completely closed, and +would cause errors if events happened before the channel was closed. This +could happen in two cases: first if the channel is shared between several +interpreters, and second if an async flush is in progress that prevents the +channel from being closed until the flush finishes. (JL) + +7/10/96 (bug fix) Fixed bugs in both "lrange" and "lreplace" commands +where too much white space was being removed. For example, the command + lreplace {\}\ hello} end end +was returning "\}\", losing the significant space in the first list +element and corrupting the list. (JO) + +7/20/96 (bug fix) The procedure pkg_mkIndex didn't work properly for +extensions that depend on Tk, because it didn't load Tk into the child +interpreter before loading the extension. Now it loads Tk if Tk is +present in the parent. (JO) + +7/23/96 (bug fix) Added compat version of strftime to fix crashes +resulting from bad implementations under Windows. (SS) + +7/23/96 (bug fix) Standard implementations of gmtime() and localtime() +under Windows did not handle dates before 1970, so they were replaced +with a revised implementation. (SS) + +7/23/96 (bug fix) Tcl would crash on exit under Borland 5.0 because +the global environ pointer was left pointing to freed memory. (SS) + +7/29/96 (bug fix) Fixed memory leak in Tcl_LoadCmd that could occur if +a package's AppInit procedure called Tcl_StaticPackage to register +static packages. (JO) + +8/1/96 (bug fix) Fixed a series of bugs in Windows sockets so that async +writebehind in the presence of read event handlers now works, and so that +async writebehind also works on sockets for which a read event handler was +declared and whose channels were then closed before the async write +finished. The bug was reported by John Loverso and Steven Wahl, +independently, test case supplied by John Loverso. (JL) + +----------------- Released patch 7.5p1, 8/2/96 ----------------------- |
