[TCLCORE] TIP #290: Registration of Custom Error Handler Scripts

[Eckhard L. <ec...@we...>]

 TIP #290: REGISTRATION OF CUSTOM ERROR HANDLER SCRIPTS 
========================================================
 Version:      $Revision: 1.3 $
 Author:       Eckhard Lehmann <ecky-l_at_web.de>
 State:        Draft
 Type:         Project
 Tcl-Version:  8.5

-------------------------------------------------------------------------

 ABSTRACT 
==========

 This TIP proposes the possibility to register custom scripts or 
 commands in the usual Tcl event handler style as error handlers. 

 RATIONALE 
===========

 Errors are thrown in the Tcl interpreter through the *error* command or 
 from a C extension that returns TCL_ERROR. When an error is thrown, the 
 global /errorInfo/ variable is filled with a rudimentary stacktrace 
 information and the error message itself. The global /errorCode/ 
 variable can contain an error code if this is provided by the command 
 that has thrown the error. 

 Errors can be caught with the *catch* command. In this case, the 
 /errorInfo/ variable is still filled with the information mentioned 
 above, but the error is not presented to the interpreter. If the error 
 is not caught, it is presented to the interpreter and the execution of 
 the current code is aborted immediately 

 The information in /errorInfo/ is in some simple cases useful for 
 reproducing and tracking down the error source and fixing the problem. 
 In more complicated cases however, /errorInfo/ includes not enough 
 information to sucessfully reproduce the error - information about the 
 applications state is missing. 

 In other languages such as LISP and SMALLTALK, this problem is 
 addressed by stopping the execution at the position where the error was 
 thrown (preserving the current callframe) and presenting the developer 
 with a console that enables him to introspect the running program. 
 Although Tcl has very good introspection capabilities, it is not 
 possible to use them in an error case, because the execution just 
 aborts and the stacktrace is unwound at once. For errors generated with 
 the *error* command, it is possible to overwrite this command and 
 provide a more advanced functionality, but this is not possible if 
 errors are generated in C code by /return TCL_ERROR/. 

 The proposed implementation addresses this problem by a custom error 
 handler that is executed whenever an error occures in the execution of 
 Tcl code. This opens a range of implementation possibilities for error 
 handling, for instance: 

     * registering a /breakpoint/ command that stops execution at the 
       error position and opens a console for introspection 

     * registering a more advanced (Tk) debugger that opens on error for 
       introspection. 

     * registering a command that captures the state of each call-frame 
       up to the one where the error was thrown and writes that state to 
       a file. This file can later be debugged (with an appropriate 
       tool) - similar to memory dump files for C debuggers. 

 SPECIFICATION 
===============

 The implementation consists of two parts: an registration command, 
 linked in as *::tcl::seterrorhandler* and various places where the 
 error handler is called if appropriate. For this to work, there are 
 some minor changes necessary to the Tcl execution engine and to the 
 Interp structure. 

    1. /tclInt.h/ - Interp introduce three new members to the Interp 
       structure: (Tcl_Obj */errorHandler/) holds the handler code to 
       execute, (int /errorHandlerFlags/) holds flags for execution 
       conditions and (int /catchLevel/) determines the current level of 
       catch blocks surrounding the executed code. 

    2. /tclInt.h/ - introduce four new macro definitions for the 
       /errorHandlerFlags/ member specified above: ERRHANDLER_ONCAUGHT 
       is set when the handler should be executed on caught errors, 
       ERRHANDLER_ONUNCAUGHT is set when the handler should be executed 
       on uncaught errors, ERRHANDLER_FINISHED indicates whether the 
       handler has been run already for the currently encountered error, 
       ERRHANDLER_RUNNING indicates whether the error handler is 
       currently running (so that it is not triggered from errors inside 
       the handler itself). 

    3. /tclEvent.c///tclInt.h/ - declare and define a new object command 
       *TclSetErrorHandlerObjCmd*(/data/, /interp/, /objc/, /objv/), 
       through which an error handler can be registered. 

    4. /tclBasic.c/ - Tcl_CreateInterp() should initialize the new 
       members of the Interp structure and register the 
       *::tcl::seterrorhandler* command. 

    5. /tclBasic.c/ - TclEvalObjvInternal() This function is called from 
       others to evaluate Tcl expressions and returns a code that can be 
       TCL_ERROR. Invoke the error handler here, if necessary. 

    6. /tclCmdAH.c/ - Tcl_CatchObjCmd() increment the /catchLevel/ 
       member in the interp structure before executing the enclosed code 
       and decrement it afterwards. The /catchLevel/ member indicates 
       whether errors are catched. 

    7. /tclExecute.c/ - enhance the two macros DECACHE_STACK_INFO() and 
       CACHE_STACK_INFO() to increment/decrement the /catchLevel/ member 
       if the following code is catched (I think this is the case when 
       (catchTop != initCatchTop) in the TclExecuteByteCode() 
       function?). This makes sure that the catch information is 
       available when code is executed by TclEvalObjvInternal(). 

    8. /tclExecute.c/ - TclExecuteByteCode (line 1796 ff) after a call 
       to TclEvalObjvInternal, unset the ERRHANDLER_FINISHED flag, if 
       the execution is at the top of the execution stack. This way, the 
       mechanism works for following errors. 

 The reference implementation fullfills this specification. It works 
 while other Tcl functionality is not affected (proven by repeated run 
 of the test suite). 

 REFERENCE IMPLEMENTATION 
==========================

 The reference implementation is available from sourceforge as patch 
 against Tcl 8.5a5 
 [<URL:http://sourceforge.net/support/tracker.php?aid=1587317>]. 

 USAGE EXAMPLE 
===============

 Here is a sample procedure that can be used to stop execution on error 
 and introspect the program on stdin/stdout. It was implemented by Neil 
 Madden as *debug-repl* and is available (with a short discussion on the 
 topic) on <URL:http://lambda-the-ultimate.org/node/1544#comment-18446:> 

   package provide debug 1.0
   
   proc up {} {
       uplevel 2 {
           breakpoint
       }
   }
   
   proc down {} {
       return -code continue
   }
   
   proc breakpoint {args} {
       set cmd ""
       set level [expr {[info level]-1}]
       set prompt "Debug ($level) % "
       while {1} {
           puts -nonewline $prompt
           flush stdout
           gets stdin line
           append cmd $line\n
           if {[info complete $cmd]} {
               set code [catch {uplevel #$level $cmd} result]
               if {$code == 0 && [string length $result]} {
                   puts stdout $result
               } elseif {$code == 3} {
                   break
               } elseif {$code == 4} {
                   # continue
                   return
               } else {
                   puts stderr $result
               }
               set prompt "Debug ($level) % "
               set cmd ""
           } else {
               set prompt "    "
           }
       }
   }

 To use it for uncaught errors, the /breakpoint/ procedure can be 
 registerred as error handler: 

   package re debug
   ::tcl::seterrorhandler -uncaught breakpoint

 When an error raises, /breakpoint/ is called in the current callframe 
 and Tcl introspection commands like *info vars* etc. can be used to get 
 information about the program state.

I think it would be helpful to add tests to the test suite that 
demonstrate this feature's effectiveness at addressing the use cases in 
the proposal.  Tests that actually show event-driven channel operations.

Re: [TCLCORE] TIP #289: Revision of [lrepeat] Argument Order

[Donald G P. <dg...@ni...>]

I skimmed the old TIP 136 messages in the TCLCORE archives.  One thing 
to note is that the existing [lrepeat] syntax in 8.5a5 was chosen in 
part to be consistent with the existing [struct::list repeat] syntax in 
the struct::list package.

There was also a good bit of wishing for a more direct way to initialize 
nested list structures without needing nested calls to [lrepeat].

I am no expert, but I think string reversal is also useful with genetic

On the other hand, you get the ability to redirect aliases or
subcommands
of ensembles to [lrepeat] calls with the elements already filled in.

Old style allows:
interp alias {} fiveTimes {} lrepeat 5

New style allows:
interp alias {} emptyList {} lrepeat {}
interp alias {} zeroVec {} lrepeat 0

I really can't say which is most useful or even if any is useful at all,
but either way you lose one ability. One that anyhow is just a proc
away.

I haven't downloaded the patch attached to Colin's RFE yet to see
(will do so tonight), but with the various ways one can call [gets] (0
to 3 arguments currently) the semantics seem like they could get a bit
messy if -maxchars were supported in all flavors.

Also I think you'd want to be able to distinguish between the case
where you got -maxchars because that is exactly what was there to be
read and when you got -maxchars because you hit the maximum.  I
suppose you could distinguish the case by requesting -maxchars [expr
{$limit + 1}] and then testing [string length $line] to see if it were
just $limit or ($limit + 1) ...

Anyway, I think [chan available] is a good fit with the new [chan]
ensembles in 8.5 and approving the TIP shouldn't preclude a separate
TIP for changing [gets] in my opinion.

[TCLCORE] Ttk now in CVS

[Jeff H. <je...@ac...>]

After review of the sandbox by various parties, we have made a first 
commit of themed Tk (Ttk, aka tile) to 8.5.  This is a branch of tile 
from v0.7.8, with some variations.  There is no Ttk or tile package in 
this, it is simply Tk 8.5a6 (which you can thankfully now request by 
exact patchlevel).

It currently builds and runs across the platforms.  There is an issue 
with 'make test' in the safe.test suite in that it fails to run due to 
some non-safe code usage in the ttk library initialization (though it 
runs fine when testing by hand ... ugh, safe interp debugging is a pain).

We will be refining and improving the actual themed parts, along with 
documentation, demos and refinement of what exactly is public for 8.5. 
I welcome everyone to start poking and prodding now though.

Enjoy,

Jeff

Michael,

your are quoting from fileevent.n:

	A channel is also considered to be readable if there is unread
	data in an input buffer, except in the special case where the
	most recent attempt to read from the channel was a gets call
	that could not find a complete line in the input buffer.

I am not aware of this special case, and think that the manpage might be
wrong.

... Writing a test script ... Ok I seem to be wrong.

Using the attached scripts (yyy = sender incomplete line, zzz = sender complete
line, xxx = receiver), I find that after each push of an incomplete line to the
socket the receiver calls the event handler only twice and then stops. Until the
next chunk is received. Without the special case it would expect it to execute
the handler rapidly without stopping, until the line has been completed ...

Interesting. Now I am wondering how this is implemented.

The reference implementation can be found here: 
http://sourceforge.net/support/tracker.php?aid=1587317.

I did not care in particular about thread safety, but the handler is 
stored and run on a "per Interp" basis.
This means that it must be registered separately for each thread - and 
when an error comes up there, the handler is run in the Interp of this 
thread (the current thread can be retrieved with [thread::id] in the 
handler script).

I did some testing with multi threads, and it works (more tests will be 
added later to the testsuite).
