-    3. Compiling and installing Tcl
-    4. Development tools
-    5. Tcl newsgroup

-
-1. Introduction
----------------
-Tcl provides a powerful platform for creating integration applications that
-tie together diverse applications, protocols, devices, and frameworks.
-When paired with the Tk toolkit, Tcl provides the fastest and most powerful
-way to create GUI applications that run on PCs, Unix, and Mac OS X.
-Tcl can also be used for a variety of web-related tasks and for creating
-powerful command languages for applications.
-
-Tcl is maintained, enhanced, and distributed freely by the Tcl community.
-Source code development and tracking of bug reports and feature requests
-takes place at:
-
-	http://core.tcl.tk/
-
-Tcl/Tk release and mailing list services are hosted by SourceForge:
-
-	http://sourceforge.net/projects/tcl/
-
-with the Tcl Developer Xchange hosted at:
-
-	http://www.tcl.tk/
-
-Tcl is a freely available open source package.  You can do virtually
-anything you like with it, such as modifying it, redistributing it,
-and selling it either in whole or in part.  See the file
-"license.terms" for complete information.
-
-2. Documentation
-----------------
-
-Extensive documentation is available at our website.
-The home page for this release, including new features, is
-	http://www.tcl.tk/software/tcltk/8.6.html
-
-Detailed release notes can be found at the file distributions page
-by clicking on the relevant version.
-	http://sourceforge.net/projects/tcl/files/Tcl/
-
-Information about Tcl itself can be found at
-	http://www.tcl.tk/about/
-
-There have been many Tcl books on the market.  Many are mentioned in the Wiki:
-	http://wiki.tcl.tk/_/ref?N=25206
-
-To view the complete set of reference manual entries for Tcl 8.6 online,
-visit the URL:
-	http://www.tcl.tk/man/tcl8.6/
-
-2a. Unix Documentation
-----------------------
-
-The "doc" subdirectory in this release contains a complete set of
-reference manual entries for Tcl.  Files with extension ".1" are for
-programs (for example, tclsh.1); files with extension ".3" are for C
-library procedures; and files with extension ".n" describe Tcl
-commands.  The file "doc/Tcl.n" gives a quick summary of the Tcl
-language syntax.  To print any of the man pages on Unix, cd to the
-"doc" directory and invoke your favorite variant of troff using the
-normal -man macros, for example
-
-		ditroff -man Tcl.n
-
-to print Tcl.n.  If Tcl has been installed correctly and your "man" program
-supports it, you should be able to access the Tcl manual entries using the
-normal "man" mechanisms, such as
-
-		man Tcl
-
-2b. Windows Documentation
--------------------------
-
-The "doc" subdirectory in this release contains a complete set of Windows
-help files for Tcl.  Once you install this Tcl release, a shortcut to the
-Windows help Tcl documentation will appear in the "Start" menu:
-
-	Start | Programs | Tcl | Tcl Help
-
-3. Compiling and installing Tcl
--------------------------------
-
-There are brief notes in the unix/README, win/README, and macosx/README about
-compiling on these different platforms.  There is additional information
-about building Tcl from sources at
-
-	http://www.tcl.tk/doc/howto/compile.html
-
-4. Development tools
----------------------------
-
-ActiveState produces a high quality set of commercial quality development
-tools that is available to accelerate your Tcl application development.
-Tcl Dev Kit builds on the earlier TclPro toolset and provides a debugger,
-static code checker, single-file wrapping utility, bytecode compiler and
-more.  More information can be found at
-
-	http://www.ActiveState.com/Tcl
-
-5. Tcl newsgroup
-----------------
-
-There is a USENET news group, "comp.lang.tcl", intended for the exchange of
-information about Tcl, Tk, and related applications.  The newsgroup is a
-great place to ask general information questions.  For bug reports, please
-see the "Support and bug fixes" section below.
-
-6. Tcl'ers Wiki
----------------
-
-A Wiki-based open community site covering all aspects of Tcl/Tk is at:
-
-	http://wiki.tcl.tk/
-
-It is dedicated to the Tcl programming language and its extensions.  A
-wealth of useful information can be found there.  It contains code
-snippets, references to papers, books, and FAQs, as well as pointers to
-development tools, extensions, and applications.  You can also recommend
-additional URLs by editing the wiki yourself.
-
-7. Mailing lists
-----------------
-
-Several mailing lists are hosted at SourceForge to discuss development or
-use issues (like Macintosh and Windows topics).  For more information and
-to subscribe, visit:
-
-	http://sourceforge.net/projects/tcl/
-
-and go to the Mailing Lists page.
-
-8. Support and Training
-------------------------
-
-We are very interested in receiving bug reports, patches, and suggestions
-for improvements.  We prefer that you send this information to us as
-tickets entered into our tracker at:
-
-	http://core.tcl.tk/tcl/reportlist
-
-We will log and follow-up on each bug, although we cannot promise a
-specific turn-around time.  Enhancements may take longer and may not happen
-at all unless there is widespread support for them (we're trying to
-slow the rate at which Tcl/Tk turns into a kitchen sink).  It's very
-difficult to make incompatible changes to Tcl/Tk at this point, due to
-the size of the installed base.
-
-The Tcl community is too large for us to provide much individual support
-for users.  If you need help we suggest that you post questions to
-comp.lang.tcl.  We read the newsgroup and will attempt to answer esoteric
-questions for which no one else is likely to know the answer.  In addition,
-see the following Web site for links to other organizations that offer
-Tcl/Tk training:
-
-	http://wiki.tcl.tk/training
-
-9. Tracking Development
------------------------
-
-Tcl is developed in public.  To keep an eye on how Tcl is changing, see
-	http://core.tcl.tk/
-
-10. Thank You
--------------
-
-We'd like to express our thanks to the Tcl community for all the
-helpful suggestions, bug reports, and patches we have received.
-Tcl/Tk has improved vastly and will continue to do so with your help.

 .SH DESCRIPTION
 .PP
-This series of C functions provides an interface whereby commands that
-are implemented in C can be evaluated, and invoke Tcl commands scripts
-and scripts, without consuming space on the C stack. The non-recursive
-evaluation is done by installing a \fItrampoline\fR, a small piece of
-code that invokes a command or script, and then executes a series of
-callbacks when the command or script returns.
+These functions provide an interface to the function stack that an interpreter
+iterates through to evaluate commands.  The routine behind a command is
+implemented by an initial function and any additional functions that the
+routine pushes onto the stack as it progresses.  The interpreter itself pushes
+functions onto the stack to react to the end of a routine and to exercise other
+forms of control such as switching between in-progress stacks and the
+evaluation of other scripts at additional levels without adding frames to the C
+stack.  To execute a routine, the initial function for the routine is called
+and then a small bit of code called a \fItrampoline\fR iteratively takes
+functions off the stack and calls them, using the value of the last call as the
+value of the routine.
 .PP
-The \fBTcl_NRCreateCommand\fR function creates a Tcl command in the
-interpreter designated by \fIinterp\fR that is prepared to handle
-nonrecursive evaluation with a trampoline. The \fIcmdName\fR argument
-gives the name of the new command. If \fIcmdName\fR contains any
-namespace qualifiers, then the new command is added to the specified
-namespace; otherwise, it is added to the global namespace. \fIproc\fR
-gives the procedure that will be called when the interpreter wishes to
-evaluate the command in an unoptimized manner, and \fInreProc\fR is
-the procedure that will be called when the interpreter wishes to
-evaluate the command using a trampoline. \fIdeleteProc\fR is a
-function that will be called before the command is deleted from the
-interpreter. When any of the three functions is invoked, it is passed
-the \fIclientData\fR parameter.
+\fBTcl_NRCallObjProc\fR calls \fInreProc\fR using a new trampoline.
 .PP
-\fBTcl_NRCreateCommand\fR deletes any existing command
-\fIname\fR already associated with the interpreter
-(however see below for an exception where the existing command
-is not deleted).
-It returns a token that may be used to refer
-to the command in subsequent calls to \fBTcl_GetCommandName\fR.
-If \fBTcl_NRCreateCommand\fR is called for an interpreter that is in
-the process of being deleted, then it does not create a new command,
-does not delete any existing command of the same name, and returns NULL.
+\fBTcl_NRCreateCommand\fR, an alternative to \fBTcl_CreateObjCommand\fR,
+resolves \fIcmdName\fR, which may contain namespace qualifiers, relative to the
+current namespace, creates a command by that name, and returns a token for the
+command which may be used in subsequent calls to \fBTcl_GetCommandName\fR.
+Except for a few cases noted below any existing command by the same name is
+first deleted.  If \fIinterp\fR is in the process of being deleted
+\fBTcl_NRCreateCommand\fR does not create any command, does not delete any
+command, and returns NULL.
 .PP
-The \fIproc\fR and \fInreProc\fR function are expected to conform to
-all the rules set forth for the \fIproc\fR argument to
-\fBTcl_CreateObjCommand\fR(3) (\fIq.v.\fR).
+\fBTcl_NREvalObj\fR pushes a function that is like \fBTcl_EvalObjEx\fR but
+consumes no space on the C stack.
 .PP
-When a command that is written to cope with evaluation via trampoline
-is invoked without a trampoline on the stack, it will usually respond
-to the invocation by creating a trampoline and calling the
-trampoline-enabled implementation of the same command. This call is done by
-means of \fBTcl_NRCallObjProc\fR. In the call to
-\fBTcl_NRCallObjProc\fR, the \fIinterp\fR, \fIclientData\fR,
-\fIobjc\fR and \fIobjv\fR parameters should be the same ones that were
-passed to \fIproc\fR. The \fInreProc\fR parameter should designate the
-trampoline-enabled implementation of the command.
+\fBTcl_NREvalObjv\fR pushes a function that is like \fBTcl_EvalObjv\fR but
+consumes no space on the C stack.
 .PP
-\fBTcl_NREvalObj\fR arranges for the script contained in \fIobjPtr\fR
-to be evaluated in the interpreter designated by \fIinterp\fR after
-the current command (which must be trampoline-enabled) returns. It is
-the method by which a command may invoke a script without consuming
-space on the C stack. Similarly, \fBTcl_NREvalObjv\fR arranges to
-invoke a single Tcl command whose words have already been separated
-and substituted. The \fIobjc\fR and \fIobjv\fR parameters give the
-words of the command to be evaluated when execution reaches the
-trampoline.
+\fBTcl_NRCmdSwap\fR is like \fBTcl_NREvalObjv\fR, but uses \fIcmd\fR, a token
+previously returned by \fBTcl_CreateObjCommand\fR or
+\fBTcl_GetCommandFromObj\fR, instead of resolving the first word of \fIobjv\fR.
+.  The name of this command must be the same as \fIobjv[0]\fR.
 .PP
-\fBTcl_NRCmdSwap\fR allows for trampoline evaluation of a command whose
-resolution is already known.  The \fIcmd\fR parameter gives a
-\fBTcl_Command\fR token (returned from \fBTcl_CreateObjCommand\fR or
-\fBTcl_GetCommandFromObj\fR) identifying the command to be invoked in
-the trampoline; this command must match the word in \fIobjv[0]\fR.
-The remaining arguments are as for \fBTcl_NREvalObjv\fR.
+\fBTcl_NRExprObj\fR pushes a function that evaluates \fIobjPtr\fR as an
+expression in the same manner as \fBTcl_ExprObj\fR but without consuming space
+on the C stack.
 .PP
-\fBTcl_NREvalObj\fR, \fBTcl_NREvalObjv\fR and \fBTcl_NRCmdSwap\fR
-all accept a \fIflags\fR parameter, which is an OR-ed-together set of
-bits to control evaluation. At the present time, the only supported flag
-available to callers is \fBTCL_EVAL_GLOBAL\fR.
-.\" TODO: Again, this is a lie. Do we want to explain TCL_EVAL_INVOKE
-.\"       and TCL_EVAL_NOERR?
-If the \fBTCL_EVAL_GLOBAL\fR flag is set, the script or command is
-evaluated in the global namespace. If it is not set, it is evaluated
-in the current namespace.
+All of the functions return \fBTCL_OK\fR if the evaluation of the script,
+command, or expression has been scheduled successfully.  Otherwise (for example
+if the command name cannot be resolved), they return \fBTCL_ERROR\fR and store
+a message as the interpreter's result.
 .PP
-\fBTcl_NRExprObj\fR arranges for the expression contained in \fIobjPtr\fR
-to be evaluated in the interpreter designated by \fIinterp\fR after
-the current command (which must be trampoline-enabled) returns. It is
-the method by which a command may evaluate a Tcl expression without consuming
-space on the C stack.  The argument \fIresultPtr\fR is a pointer to an
-unshared Tcl_Obj where the result of expression evaluation is to be written.
-If expression evaluation returns any code other than TCL_OK, the
-\fIresultPtr\fR value is left untouched.
-.PP
-All of the routines return \fBTCL_OK\fR if command or expression invocation
-has been scheduled successfully. If for any reason the scheduling cannot
-be completed (for example, if the interpreter is unable to find
-the requested command), they return \fBTCL_ERROR\fR with an
-appropriate message left in the interpreter's result.
-.PP
-\fBTcl_NRAddCallback\fR arranges to have a C function called when the
-current trampoline-enabled command in the Tcl interpreter designated
-by \fIinterp\fR returns.  The \fIpostProcPtr\fR argument is a pointer
-to the callback function, which must have arguments and return value
-consistent with the \fBTcl_NRPostProc\fR data type:

+.PP
+A persistent connection allows multiple HTTP/1.1 transactions to be
+carried over the same TCP connection.  Pipelining allows a
+client to make multiple requests over a persistent connection without
+waiting for each response.  The server sends responses in the same order
+that the requests were received.
+.PP
+If a POST request fails to complete, typically user confirmation is
+needed before sending the request again.  The user may wish to verify
+whether the server was modified by the failed POST request, before
+sending the same request again.
+.PP
+A HTTP request will use a persistent socket if the call to
+\fBhttp::geturl\fR has the option \fB-keepalive true\fR. It will use
+pipelining where permitted if the \fBhttp::config\fR option
+\fB-pipeline\fR is boolean \fBtrue\fR (its default value).
+.PP
+The http package maintains no more than one persistent connection to each
+server (i.e. each value of
+.QW "domain:port" ).
+If \fBhttp::geturl\fR is called to make a request over a persistent
+connection while the connection is busy with another request, the new
+request will be held in a queue until the connection is free.
+.PP
+The http package does not support HTTP/1.0 persistent connections
+controlled by the \fBKeep-Alive\fR header.
+.SS "SPECIAL CASES"
+.PP
+This subsection discusses issues related to closure of the
+persistent connection by the server, automatic retry of failed requests,
+the special treatment necessary for POST requests, and the options for
+dealing with these cases.
+.PP
+In accordance with RFC 7230, \fBhttp::geturl\fR does not pipeline
+requests that use the POST method.  If a POST uses a persistent
+connection and is not the first request on that connection,
+\fBhttp::geturl\fR waits until it has received the response for the previous
+request; or (if \fBhttp::config\fR option \fB-postfresh\fR is boolean \fBtrue\fR) it
+uses a new connection for each POST.
+.PP
+If the server is processing a number of pipelined requests, and sends a
+response header
+.QW "\fBConnection: close\fR"
+with one of the responses (other than the last), then subsequent responses
+are unfulfilled. \fBhttp::geturl\fR will send the unfulfilled requests again
+over a new connection.
+.PP
+A difficulty arises when a HTTP client sends a request over a persistent
+connection that has been idle for a while.  The HTTP server may
+half-close an apparently idle connection while the client is sending a
+request, but before the request arrives at the server: in this case (an
+.QW "asynchronous close event" )
+the request will fail.  The difficulty arises because the client cannot
+be certain whether the POST modified the state of the server.  For HEAD or
+GET requests, \fBhttp::geturl\fR opens another connection and retransmits
+the failed request. However, if the request was a POST, RFC 7230 forbids
+automatic retry by default, suggesting either user confirmation, or
+confirmation by user-agent software that has semantic understanding of
+the application.  The \fBhttp::config\fR option \fB-repost\fR allows for
+either possibility.
+.PP
+Asynchronous close events can occur only in a short interval of time.  The
+\fBhttp\fR package monitors each persistent connection for closure by the
+server.  Upon detection, the connection is also closed at the client end,
+and subsequent requests will use a fresh connection.
+.PP
+If the \fBhttp::geturl\fR command is called with option \fB-keepalive true\fR,
+then it will both try to use an existing persistent connection
+(if one is available), and it will send the server a
+.QW "\fBConnection: keep-alive\fR"
+request header asking to keep the connection open for future requests.
+.PP
+The \fBhttp::config\fR options \fB-pipeline\fR, \fB-postfresh\fR, and
+\fB-repost\fR relate to persistent connections.
+.PP
+Option \fB-pipeline\fR, if boolean \fBtrue\fR, will pipeline GET and HEAD requests
+made
+over a persistent connection.  POST requests will not be pipelined - if the
+POST is not the first transaction on the connection, its request will not
+be sent until the previous response has finished.  GET and HEAD requests
+made after a POST will not be sent until the POST response has been
+delivered, and will not be sent if the POST fails.
+.PP
+Option \fB-postfresh\fR, if boolean \fBtrue\fR, will override the \fBhttp::geturl\fR option
+\fB-keepalive\fR, and always open a fresh connection for a POST request.
+.PP
+Option \fB-repost\fR, if \fBtrue\fR, permits automatic retry of a POST request
+that fails because it uses a persistent connection that the server has
+half-closed (an
+.QW "asynchronous close event" ).
+Subsequent GET and HEAD requests in a failed pipeline will also be retried.
+\fIThe -repost option should be used only if the application understands
+that the retry is appropriate\fR - specifically, the application must know
+that if the failed POST successfully modified the state of the server, a repeat POST
+would have no adverse effect.

+ *	index value in the C signed int range.  Note that this includes
+ *	index values that are integers as presented and it includes index
+ *      arithmetic expressions. The absolute index values that can be
+ *	directly meaningful as an index into either a list or a string are
+ *	those integer values >= TCL_INDEX_START (0)
+ *	and < TCL_INDEX_AFTER (INT_MAX).
+ *      The largest string supported in Tcl 8 has bytelength INT_MAX.
+ *      This means the largest supported character length is also INT_MAX,
+ *      and the index of the last character in a string of length INT_MAX
+ *      is INT_MAX-1.
+ *
+ *      Any absolute index value parsed outside that range is encoded
+ *      using the before and after values passed in by the
+ *      caller as the encoding to use for indices that are either
+ *      less than or greater than the usable index range. TCL_INDEX_AFTER
+ *      is available as a good choice for most callers to use for
+ *      after. Likewise, the value TCL_INDEX_BEFORE is good for
+ *      most callers to use for before.  Other values are possible
+ *      when the caller knows it is helpful in producing its own behavior
+ *      for indices before and after the indexed item.
+ *
+ *      A token can also be parsed as an end-relative index expression.
+ *      All end-relative expressions that indicate an index larger
+ *      than end (end+2, end--5) point beyond the end of the indexed
+ *      collection, and can be encoded as after.  The end-relative
+ *      expressions that indicate an index less than or equal to end
+ *      are encoded relative to the value TCL_INDEX_END (-2).  The
+ *      index "end" is encoded as -2, down to the index "end-0x7ffffffe"
+ *      which is encoded as INT_MIN. Since the largest index into a
+ *      string possible in Tcl 8 is 0x7ffffffe, the interpretation of
+ *      "end-0x7ffffffe" for that largest string would be 0.  Thus,
+ *      if the tokens "end-0x7fffffff" or "end+-0x80000000" are parsed,
+ *      they can be encoded with the before value.
+ *
+ *      These details will require re-examination whenever string and
+ *      list length limits are increased, but that will likely also
+ *      mean a revised routine capable of returning Tcl_WideInt values.
