Author: Keith Packard <keithp@keithp.com>
Date:   Mon May 19 13:22:11 2008 -0700

    Non-interactive stdin is always available for reading.
    
    Failing to set the 'stdinOwned' flag meant that you could never read from
    stdin which wasn't a terminal. Oops.

commit d0604e797cf194eb025a1784766ebea8cf38ec87
Author: Keith Packard <keithp@keithp.com>
Date:   Wed Mar 26 23:21:41 2008 -0700

    Allow background nickle to not poll on tty ownership
    
    When stdin is connected to a terminal but nickle is not the foreground
    process on that terminal, the io code would poll to wait for ownership to
    flip back to nickle so that reads could be performed without generating a
    signal. Now, nickle waits until someone actually tries to read from the
    terminal before starting to poll. This means that simple background
    processing nickle programs will not poll every 100ms.

Author: Keith Packard <keithp@keithp.com>
Date:   Wed Mar 26 16:22:44 2008 -0700

    Remove support for non-SIGIO pipes
    
    Older version of the kernel (before 2001) failed to generate SIGIO on pipes,
    so nickle had code to poll instead. I think we can safely remove that code
    now.

Author: Keith Packard <keithp@keithp.com>
Date:   Wed Mar 19 23:12:13 2008 -0700

    Avoid having the 'pretty_print' builtin show two error messages.
    
    NamespaceLocate takes a 'complain' boolean that will print out an error
    message, but the pretty_print command also raises an exception when it fails
    to find the name. Two errors is at least one too many here.

Date:   Wed Mar 19 17:19:26 2008 -0700

    Fix a few broken calls to RaiseStandardException.
    
    RaiseStandardException was changed to remove the need to pass a string
    argument first, but a few calls were not converted, and C varargs cannot
    catch these errors. I checked all calls and they appear OK now.

    Divide by zero declaration is (real, real), not (string, real, real)
    
    The type declaration for the divide_by_zero exception was wrong.

    Change yacc invocation to make yacc tables const.
    
    byacc (and bison) leave the yacc tables in writable pages; this change edits
    the C output code to move them to read-only pages.

Author: Keith Packard <keithp@keithp.com>
Date:   Mon Feb 25 10:00:51 2008 -0800

    Track profile ticks per function in addition to per statement.
    
    Recursive functions make gathering useful profile data harder. This avoids
    some recursion mis-counting by separately tracking function and statement
    lifetimes.

    Raise io_eof exception when reading past EOF.
    
    Instead of returning -1, raise an exception so that applications don't end
    up spinning at EOF. Applications should check for File::end before reading
    or catch the exception.

Author: Keith Packard <keithp@keithp.com>
Date:   Mon Feb 11 08:28:13 2008 -0800

    Remove first string arg from RaiseStandardException.
    
    Every standard exception was required to have a string for the first
    argument, which isn't always desired. Eliminating this forced first argument
    allows each exception to have the desired arguments.

    Socket: Provide varargs versions of bind and connect
    
    With this change, the hostname is now not-required, (and even not
    allowed), for an AF_UNIX socket. Also, for an AF_INET socket the
    port can now be an integer as well as a string service or port.

    Signal exception arguments were not getting forwarded.
    
    Exception arguments must land in thread value register so that they can be
    passed to the exception handler (if any). Also, add a test for signaling.

Date:   Sun Feb 3 07:22:28 2008 -0800

    Add signal exceptions, treat SIGINT as raise signal(2)
    
    SIGINT used to interrupt the current thread and enter the debugger with the
    thread 'interrupted'; in this state, the thread could be continued. However,
    this means that threads cannot catch SIGINT and cleanup at process exit.
    This commit changes all this around so that SIGINT simply raises a signal
    exception in all threads.
    
    This patch also keeps the interpreter running until all threads have exited.

Date:   Sat Feb 2 22:07:54 2008 +1100

    Add 'signal' exception and 'send_signal' function.
    
    The 'send_signal' function raises a 'signal' exception in another thread,
    causing it to abort processing immediately.

    Twixt mark function shouldn't reference leave instruction.
    
    Instructions cannot be referenced directly, only the object block containing
    them. The twixt continuation already has a reference to the object, so the
    extra MemReference on the leave instruction is spurious (and causes
    crashing).

    Support autoload/autoimport of nested namespaces.
    
    While nested namespaces could be loaded, the filenames would reference only
    the last element making it hard to actually use them. This change
    glues the namespace elements together with '-' when building filenames.

    failure (status 1).

    Function declarations would segfault the pretty printer.
    
    	void g () { void f (int i); }

    Fixed by adding pretty printing code to handle this case.

    Floating floor and ceil functions broken for values with no integer part.
    
    The ceiling of any positive fraction < 1 is 1, the floor of any negative

    Make // and % operators modulus division operators.
    
    Herry S Warren Jr. defines three kinds of division --
    truncating, floor and modulus. For all three kinds he
    requires a simple invarient:
    
    	dividend = quotient * divisor + remainder
    
    Modulus division additionaly requires
    
     	0 <= remainder < abs (divisor)
    
    Floor division sets:
    
    	quotient = floor (dividend / divisor)
    	remainder = dividend - quotient * divisor
    
    Truncating division has
    
    	quotient = round_towards_zero (dividend / divisor)
    	remainder = dividend - quotient * divisor
    
    We select modulus division as it makes the most sense when you treat the
    values as a ring centered at zero.

    Allow . in struct initializers.
    
    C places a '.' before the structure member name in initializers, which
    would eliminate a shift/reduce conflict in the grammar. Nickle has not
    allowed the dot in the past, so instead of requiring it, we'll just make it
    optional, which doesn't eliminate the conflict, but at least works.

    Manage file buffer chains with explicit malloc/free.
    
    Buffer chains must have life equal to the file they belong to; an
    unreferenced file may still have buffered data, so the buffers cannot be
    reclaimed. The nickle GC does not have a separate pass that checks to see
    which objects can be freed, rather it assumes that such objects are
    self-contained.
    
    Hence, anything hanging off of an object which can refuse to
    be reclaimed must not have been allocated from the nickle GC system. Yes,
    this is a significant limitation to this allocator.
    
    Someday I'll figure out a good general fix for this problem, right now we'll
    stop segfaults when applications drop file references without closing them.

    Uninitialized value visible during MemCollect in Catch record.
    
    Newly allocated memory is uninitialized and may contain garbage. If the
    allocator may be called during initialization of the object, all object
    fields must be initialized to a valid value before any further allocation
    occurs. This wasn't happening in the Catch object as the exception member
    was left unitialized while the continuation member was allocated.

    Correct catch nest level inside multi-peer try/catch blocks.
    
    When a try/catch block has multiple catch elements, each of the catch blocks
    is a 'peer' of the others, exceptions raised inside any of them will not be
    handled by the peer catch. To do this, the compiler generates unwind code to
    set the exception stack to the right position before jumping into the
    exception handler function.
    
    This means that while compiling the exception handler function, the catch
    stack must match that from before entering the top-most catch peer. This was
    done by not pushing non-local objects on the non local stack while recursing
    to the peer catch block. However, aside from the nested catch blocks, the
    nested statement *must* have the correct number of non-local goto blocks.
    
    Instead of attempting to work around a shortage of non-local goto blocks
    while compiling the statement inside the try/catch, the non-local stack is
    stripped of peer catch blocks while compiling the exception handler.

    Doc string for File::print confused -1 (default) with -2 (sufficient).
    
    The documentation string for File::print stated that -1 used sufficient
    precision to represent the output exactly. This is wrong. -1 is an
    alias for the default precision (10). -2 is the value used to indicate
    sufficient precision should be used to represent the value exactly.

    Fixes for various buglets including mis-parsing single-character options and using the wrong variable in an error message.
    Changed the semantics of argv. It is now dim 0 iff the program reads from standard input *and* was not passed arguments.

    Older versions of GNU Make (before 3.80, apparently) seem to require shell invocation macros to be defined with :=
    Solaris yacc gives an error if a type is given to a non-terminal that does not actually appear in the grammar. Removed opttypename.

    Big rewrite of parse-args code to work better and be more usable. Will now accomodate Nickle startup.
    Changes to use parse-args instead of ad hoc argument parsing at startup. Changed key conventions: -e now takes a single argument; -e, -f, and -l can be freely mixed; interactive mode can now have argv through "--"; others?
    Fixed trivial spelling error.

    Set SO_BROADCAST just in case
    CompileCall with auto_reference == True must not return a pointer to the return type as this function is called from CompileLvalue which is defined to return the type of the underlying object, not a pointer to that type. The alternative is to return a reference type, and I'm fairly sure that's not right as & is supposed to return a pointer type, not a reference type, right?
    Make sure the nickle headers are installed
    Add a test for reference types which checks the above change

    &poly foo() { ... }; &poly x = &foo(); Compiler generated 'Dereference, do_reference' in this call which caused the object referenced by foo() to be copied. Notice case of call to reference value function followed by & operator and elide the Dereference/do_reference pair.

    Missed a few pointers in mark code
    A nasty one -- jumping into a continuation that is referenced from the thread object itself (catch) drops the reference to the continuation before finishing the jump. Combined with careful MemCollect timing, this can break the resulting thread state.
    Add assertions to make sure the stack pointer is in range
    Deal with non-blocking file descriptors

    Parallel catch blocks are peers, not nested. This affects how FarJump execution inside them happens; in particular, all of the peer catches are unwound before the handler is invoked so all jumps from inside use the same NonLocal data structure. Also added yet more debugging to continuation execution.

    Ok, so the previous change was incomplete.
    Restructure CompileLvalue so that the processing of ampersands is unified. The unified rules were changed so that the value of a reference to a reference type is converted to a pointer instead of a reference. That seems confusing enough. Basically, it allows:
    &int r;
    *&int pr = & & r;

    Change resizable array representation to be a vector of single entry boxes. This allows clean semantics for array shrinking -- outranged elements still have storage, but are no longer accessible through the array, even if the array is subsequently enlarged.
    Change File::end semantic to actually peek at the file and check whether the next read would return EOF. This seems like the only useful semantic here.

    (this change was lost by a mistaken commit to the wrong repository...)
    Couple of valgrind problems: Initialize branch.offset field in all instructions so that CompileIsReachable can blindly fetch them before the real offset is set. Set the static link offset to zero for names contained in declarations; it was otherwise uninitialized.

Author: Keith Packard <keithp@keithp.com>
Date:   Mon Oct 13 18:14:51 2003 +0000

    Leave file descriptors blocking. Check with select before read/write. This allows nickle files to be shared with subprocesses cleanly. It does introduce a minor race if nickle and another application attempt to read at the same time, nickle may select and then try to read which may in fact block. It's a small window, so I'm not going to worry about it, the benefit of leaving fds blocking is too great.

    Array types include dimension expressions. These are now evaluated where the type is declared and stored in the appropriate context.
    OpGlobal/OpLocal/OpStatic now all changed to not point at the symbol table and instead point directly to storage. Should be faster, needed to reference array dimension storage created above.

    First shot at debianization. Not quite there yet. In particular you have to move the nickle directory to "nickle-(version)" before the packaging tools will know how to work with it. Also I haven't quite decided how to handle the ChangeLog and COPYING files; I want this to behave like a native Debian package, but that requires moving those files to debian/changelog and debian/copyright, respectively, and imposing a machine-readable format on the changelog. For now I hack around the copyright file and ignore the changelog.

    Changes for Solaris (and general portability):
    Fix pair of actions in gram.y with no symbol between them.
    Replace builtin.c setenv() and unsetenv() calls with putenv() + C code. (Arguably not done yet: should dispense with putenv() as well.) TODO: Is the variable passed to putenv() rooted properly?
    Instances of HAS_SIGACTION should be HAVE_SIGACTION TODO: Do systems with HAVE_SIGACTION false actually work?
    Replace uses of SIG_IGN and SIG_DFL with "UNIX98" sigignore(), sigrelse() when available: this avoids prototype hell, and may be "better".
    Completely revamp configure.in readline library support: now does a very complicated thing when e.g. --with-readline=/pkgs/gnu is given. In the process, split bloated readline code to AC_LIB_READLINE in acinclude.m4. TODO: Is this the right way to handle readline yet? Can this code be replaced with code that doesn't depend on semantics of -L and -R options to GCC/loader?

    + Now that declarations are expressions, they often need a type and value. Declarations uniformly have the current type and value of the last declared variable. This may not be reasonable for static/global variables, but other alternatives are less plausible:
    function foo () { int i = (static int k = 1); k++; return i; }
    k is initialized when the func is evaluated (i.e. when foo is assigned to). So, each time foo is called, that value will be incremented by 1 leaving foo returning an increasing sequence of values.

    Clean up builtin function names. Now all are of the form:
    do_Namespace_function
    Predicates are prefixed with 'is_'. More functions moved into separate namespaces.
    Global replacement of 'Namespace' for 'Scope'
    Add type predicate functions and functions to extract pieces of rationals
    Fixed a bug in compiling function declarations which left an extra func on the stack.
    Add Debugger.dump to examine compiler output.
    Trap /0 in FloatDivide. Compute necessary intermediate precision correctly as well. Implement FloatMod. Fix floating == 0
    Allow 'print foo.bar.bletch' in grammar.
    Complain about comments left open at EOF.
    Implement lots of nifty math primitives in math.5c (sqrt, cbrt, exp, log, log10, sin, cos, tan, arcsin, arccos, arctan, arctan2)

    Make FloatFloor return Integer when possible.
    Recover from variable definition botch in debugger, new variables are stuck into class_auto even though the frame is active, references to those variables trash the current frame. This may be hard to fix; the kludge here only avoids crashing.
    Clean up a bit more lint.

    Argument typechecking was walking actuals in the wrong direction.
    Builds without warnings using
    -Wall -Wpointer-arith -Wstrict-prototypes \
    -Wmissing-prototypes -Wmissing-declarations \
    -Wnested-externs-Wall

Date:   Fri Feb 23 06:32:51 2001 +0000

    Pretty massive rewrite of the syntax to allow for full type declarations, typedefs and cleaner initializers.
    Everything that can be typechecked at compile time is now done, still missing is full run-time typechecking using compound types. That should be easy to add.
    Still ugly:
    typedef int foo;
    type foo bar; <- yuck!
    The current compiler won't allow for lexical-based typedefs like C uses, so we're left with allowing 'NAME' to appear for a typedef name. Yes, this is ugly.
