// -DSILENT disables statistics printing, and improves performance.
// -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
// altered stubborn objects, at substantial performance cost.
// Use only for incremental collector debugging.
// -DFIND_LEAK causes the collector to assume that all inaccessible
// objects should have been explicitly deallocated, and reports exceptions.
// Finalization and the test program are not usable in this mode.
// -DSOLARIS_THREADS enables support for Solaris (thr_) threads.
// (Clients should also define SOLARIS_THREADS and then include
// gc.h before performing thr_ or GC_ operations.)
// This is broken on nonSPARC machines.
// -DALL_INTERIOR_POINTERS allows all pointers to the interior
// of objects to be recognized. (See gc_priv.h for consequences.)
// -DSMALL_CONFIG tries to tune the collector for small heap sizes,
// usually causing it to use less space in such situations.
// Incremental collection no longer works in this case.
// -DLARGE_CONFIG tunes the collector for unusually large heaps.
// Necessary for heaps larger than about 500 MB on most machines.
// Recommended for heaps larger than about 64 MB.
// -DDONT_ADD_BYTE_AT_END is meaningful only with
// -DALL_INTERIOR_POINTERS. Normally -DALL_INTERIOR_POINTERS
// causes all objects to be padded so that pointers just past the end of
// an object can be recognized. This can be expensive. (The padding
// is normally more than one byte due to alignment constraints.)
// -DDONT_ADD_BYTE_AT_END disables the padding.
// -DNO_SIGNALS does not disable signals during critical parts of
// the GC process. This is no less correct than many malloc
// implementations, and it sometimes has a significant performance
// impact. However, it is dangerous for many not-quite-ANSI C
// programs that call things like printf in asynchronous signal handlers.
// -DOPERATOR_NEW_ARRAY declares that the C++ compiler supports the
// new syntax "operator new[]" for allocating and deleting arrays.
// See gc_cpp.h for details. No effect on the C part of the collector.
// This is defined implicitly in a few environments.
// -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be defined
// as aliases for X, GC_realloc, and GC_free, respectively.
// Calloc is redefined in terms of the new malloc. X should
// be either GC_malloc or GC_malloc_uncollectable.
// The former is occasionally useful for working around leaks in code
// you don't want to (or can't) look at. It may not work for
// existing code, but it often does. Neither works on all platforms,
// since some ports use malloc or calloc to obtain system memory.
// (Probably works for UNIX, and win32.)
// -DNO_DEBUG removes GC_dump and the debugging routines it calls.
// Reduces code size slightly at the expense of debuggability.

<h2>
<a NAME="Introduction"></a>Introduction</h2>
This is the README file for the&nbsp;<span CLASS=LXRSHORTDESC>JavaScript
Reference (JSRef) implementation.</span> It consists of build conventions
and instructions, source code conventions, a design walk-through, and a
brief file-by-file description of the source.
<p><span CLASS=LXRLONGDESC>JSRef builds a library or DLL containing the
JavaScript runtime (compiler, interpreter, decompiler, garbage collector,
atom manager, standard classes). It then compiles a small "shell" program
and links that with the library to make an interpreter that can be used
interactively and with test .js files to run scripts.&nbsp; The code has
no dependencies on the Navigator code.</span>
<p><i>Quick start tip</i>: skip to "Using the JS API" below, build the
js shell, and play with the object named "it" (start by setting 'it.noisy
= true').
<h2>
<a NAME="Build"></a>Build conventions (standalone JS engine and shell)</h2>
These build directions refer only to building the standalone JavaScript
engine and shell.&nbsp; To build within the browser, refer to the <a href="http://www.mozilla.org/docs/">build
directions</a> on the mozilla.org website.
<p>By default, all platforms build a version of the JS engine that is <i>not</i>
threadsafe.&nbsp; If you require thread-safety, you must also populate
the <tt>mozilla/dist</tt> directory with <a href="http://www.mozilla.org/docs/tplist/catCode/nsprdesc.htm">NSPR</a>
headers and libraries.&nbsp; (NSPR implements a portable threading library,
among other things.&nbsp; The source is downloadable via <a href="http://www.mozilla.org/cvs.html">CVS</a>
from <tt><a href="http://lxr.mozilla.org/mozilla/source/nsprpub">mozilla/nsprpub</a></tt>.)&nbsp;
Next, you must define <tt>JS_THREADSAFE</tt> when building the JS engine,
either on the command-line (gmake/nmake) or in a universal header file.
<h3>
Windows</h3>
<ul>
<li>
Use MSVC 4.2 or 5.0.</li>
<li>
For building from the IDE use <tt>js/src/js.mdp</tt>.&nbsp; (<tt>js.mdp</tt>
is an MSVC4.2 project file, but if you load it into MSVC5, it will be converted
to the newer project file format.)&nbsp; <font color="#CC0000">NOTE: makefile.win
is an nmake file used only for building the JS-engine in the Mozilla browser.&nbsp;
Don't attempt to use it to build the standalone JS-engine.</font></li>
<li>
If you prefer to build from the command-line, use '<tt>nmake -f js.mak</tt>'</li>
<li>
Executable shell <tt>js.exe</tt> and runtime library <tt>js32.dll</tt>
are created in either <tt>js/src/Debug</tt> or <tt>js/src/Release</tt>.</li>
</ul>
<h3>
Macintosh</h3>
<ul>
<li>
Use CodeWarrior 3.x</li>
<li>
Load the project file <tt>js:src:macbuild:JSRef.mcp </tt>and select "Make"
from the menu.</li>
</ul>
<h3>
Unix</h3>
<ul>
<li>
Use '<tt>gmake -f Makefile.ref</tt>' to build. To compile optimized code,
pass <tt>BUILD_OPT=1</tt> on the gmake command line or preset it in the
environment or <tt>Makefile.ref</tt>.&nbsp; <font color="#CC0000">NOTE:
Do not attempt to use Makefile to build the standalone JavaScript engine.&nbsp;
This file is used only for building the JS-engine in the Mozilla browser.</font></li>
<li>
<font color="#000000">Each platform on which JS is built must have a <tt>*.mk</tt>
configuration file in the <tt>js/src/config</tt> directory.&nbsp; The configuration
file specifies the compiler/linker to be used and allows for customization
of command-line options.&nbsp; To date, the build system has been tested
on Solaris, AIX, HP/UX, OSF, IRIX, x86 Linux and Windows NT.</font></li>
<li>
<font color="#000000">Most platforms will work with either the vendor compiler
</font>or
<a href="ftp://prep.ai.mit.edu/pub/gnu">gcc</a>.&nbsp;
(Except that HP builds only work using the native compiler.&nbsp; gcc won't
link correctly with shared libraries on that platform.&nbsp; If someone
knows a way to fix this, <a href="mailto:wynholds@netscape.com">let us
know</a>.)</li>
<li>
<font color="#000000">If you define <tt>JS_LIVECONNECT</tt>, gmake will
descend into the liveconnect directory and build
<a href="http://lxr.mozilla.org/mozilla/source/js/src/liveconnect/README.html">LiveConnect</a>
after building the JS engine.</font></li>
<li>
To build a binary drop (a zip'ed up file of headers, libraries, binaries),
check out <tt>mozilla/config</tt> and <tt>mozilla/nsprpub/config</tt>.&nbsp;
Use '<tt>gmake -f Makefile.ref nsinstall-target all export ship</tt>'</li>
</ul>
<h2>
<a NAME="Debugging"></a>Debugging notes</h2>
<ul>
<li>
To turn on GC instrumentation, define <tt>JS_GCMETER</tt>.</li>
<li>
To turn on the arena package's instrumentation, define <tt>JS_ARENAMETER</tt>.</li>
<li>
To turn on the hash table package's metering, define <tt>JS_HASHMETER</tt>.</li>
</ul>
<h2>
<a NAME="Conventions"></a>Naming and coding conventions</h2>
<ul>
<li>
Public function names begin with <tt>JS_</tt> followed by capitalized "intercaps",
e.g. <tt>JS_NewObject</tt>.</li>
<li>
Extern but library-private function names use a <tt>js_</tt> prefix and
mixed case, e.g. <tt>js_LookupSymbol</tt>.</li>
<li>
Most static function names have unprefixed, mixed-case names: <tt>GetChar</tt>.</li>
<li>
But static native methods of JS objects have lowercase, underscore-separated
or intercaps names, e.g., <tt>str_indexOf</tt>.</li>
<li>
And library-private and static data use underscores, not intercaps (but
library-private data do use a <tt>js_</tt> prefix).</li>
<li>
Scalar type names are lowercase and js-prefixed: <tt>jsdouble</tt>.</li>
<li>
Aggregate type names are JS-prefixed and mixed-case: <tt>JSObject.</tt></li>
<li>
Macros are generally <tt>ALL_CAPS </tt>and underscored, to call out potential
side effects, multiple uses of a formal argument, etc. - Four spaces of
indentation per statement nesting level.</li>
<li>
Tabs are taken to be eight spaces, and an Emacs magic comment at the top
of each file tries to help. If you're using MSVC or similar, you'll want
to set tab width to 8, or convert these files to be space-filled.</li>
<li>
DLL entry points have their return type expanded within a <tt>JS_PUBLIC_API()</tt>
macro call, to get the right Windows secret type qualifiers in the right
places for both 16- and 32-bit builds.</li>
<li>
Callback functions that might be called from a DLL are similarly macroized
with <tt>JS_STATIC_DLL_CALLBACK</tt> (if the function otherwise would be
static to hide its name) or <tt>JS_DLL_CALLBACK</tt> (this macro takes
no type argument; it should be used after the return type and before the
function name).</li>

<a NAME="Design"></a>Design walk-through</h2>
This section must be brief for now -- it could easily turn into a book.
<h4>
JS "JavaScript Proper"</h4>
JS modules declare and implement the JavaScript compiler, interpreter,
decompiler, GC and atom manager, and standard classes.
<p>JavaScript uses untyped bytecode and runtime type tagging of data values.
The <tt>jsval</tt> type is a signed machine word that contains either a
signed integer value (if the low bit is set), or a type-tagged pointer
or boolean value (if the low bit is clear). Tagged pointers all refer to
8-byte-aligned things in the GC heap.
<p>Objects consist of a possibly shared structural description, called
the map or scope; and unshared property values in a vector, called the
slots. Object properties are associated with nonnegative integers stored
in <tt>jsval</tt>'s, or with atoms (unique string descriptors) if named
by an identifier or a non-integral index expression.
<p>Scripts contain bytecode, source annotations, and a pool of string,
number, and identifier literals. Functions are objects that extend scripts
or native functions with formal parameters, a literal syntax, and a distinct
primitive type ("function").
<p>The compiler consists of a recursive-descent parser and a random-logic
rather than table-driven lexical scanner. Semantic and lexical feedback
are used to disambiguate hard cases such as missing semicolons, assignable
expressions ("lvalues" in C parlance), etc. The parser generates bytecode
as it parses, using fixup lists for downward branches and code buffering
and rewriting for exceptional cases such as for loops. It attempts no error
recovery. The interpreter executes the bytecode of top-level scripts, and
calls itself indirectly to interpret function bodies (which are also scripts).
All state associated with an interpreter instance is passed through formal
parameters to the interpreter entry point; most implicit state is collected
in a type named JSContext. Therefore, all API and almost all other functions
in JSRef take a JSContext pointer as their first argument.
<p>The decompiler translates postfix bytecode into infix source by consulting
a separate byte-sized code, called source notes, to disambiguate bytecodes
that result from more than one grammatical production.
<p>The GC is a mark-and-sweep, non-conservative (perfect) collector. It
can allocate only fixed-sized things -- the current size is two machine
words. It is used to hold JS object and string descriptors (but not property
lists or string bytes), and double-precision floating point numbers. It
runs automatically only when maxbytes (as passed to <tt>JS_Init()</tt>)
bytes of GC things have been allocated and another thing-allocation request
is made. JS API users should call <tt>JS_GC()</tt> or <tt>JS_MaybeGC()</tt>
between script executions or from the branch callback, as often as necessary.
<p>An important point about the GC's "perfection": you must add roots for
new objects created by your native methods if you store references to them
into a non-JS structure in the malloc heap or in static data. Also, if
you make a new object in a native method, but do not store it through the
<tt>rval</tt>
result parameter (see math_abs in the "Using the JS API" section above)
so that it is in a known root, the object is guaranteed to survive only
until another new object is created. Either lock the first new object when
making two in a row, or store it in a root you've added, or store it via
rval.
<p>The atom manager consists of a hash table associating strings uniquely
with scanner/parser information such as keyword type, index in script or
function literal pool, etc. Atoms play three roles in JSRef: as literals
referred to by unaligned 16-bit immediate bytecode operands, as unique
string descriptors for efficient property name hashing, and as members
of the root GC set for perfect GC. This design therefore requires atoms
to be manually reference counted, from script literal pools (<tt>JSAtomMap</tt>)
and object symbol (<tt>JSSymbol</tt>) entry keys.
<p>Native objects and methods for arrays, booleans, dates, functions, numbers,
and strings are implemented using the JS API and certain internal interfaces
used as "fast paths".
<p>In general, errors are signaled by false or unoverloaded-null return
values, and are reported using <tt>JS_ReportError()</tt> or one of its
variants by the lowest level in order to provide the most detail. Client
code can substitute its own error reporting function and suppress errors,
or reflect them into Java or some other runtime system as exceptions, GUI
dialogs, etc..
<h2>
File walk-through (BADLY OUT OF DATE!)</h2>
<h4>
jsapi.c, jsapi.h</h4>
The public API to be used by almost all client code.&nbsp; If your client
code can't make do with <tt>jsapi.h</tt>, and must reach into a friend
or private js* file, please let us know so we can extend <tt>jsapi.h</tt>
to include what you need in a fashion that we can support over the long
run.
<h4>
jspubtd.h, jsprvtd.h</h4>
These files exist to group struct and scalar typedefs so they can be used
everywhere without dragging in struct definitions from N different files.
The <tt>jspubtd.h</tt> file contains public typedefs, and is included by
<tt>jsapi.h</tt>.
The <tt>jsprvtd.h</tt> file contains private typedefs and is included by
various .h files that need type names, but not type sizes or declarations.
<h4>
jsdbgapi.c, jsdbgapi.h</h4>
The Debugging API, still very much under development. Provided so far:
<ul>
<li>
Traps, with which breakpoints, single-stepping, step over, step out, and
so on can be implemented. The debugger will have to consult jsopcode.def
on its own to figure out where to plant trap instructions to implement
functions like step out, but a future jsdbgapi.h will provide convenience
interfaces to do these things. At most one trap per bytecode can be set.
When a script (<tt>JSScript</tt>) is destroyed, all traps set in its bytecode
are cleared.</li>
<li>
Watchpoints, for intercepting set operations on properties and running
a debugger-supplied function that receives the old value and a pointer
to the new one, which it can use to modify the new value being set.</li>
<li>
Line number to PC and back mapping functions. The line-to-PC direction
"rounds" toward the next bytecode generated from a line greater than or
equal to the input line, and may return the PC of a for-loop update part,
if given the line number of the loop body's closing brace. Any line after
the last one in a script or function maps to a PC one byte beyond the last
bytecode in the script. An example, from perfect.js:</li>
<pre><tt>14&nbsp;&nbsp; function perfect(n)
15&nbsp;&nbsp; {
16&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("The perfect numbers up to " +&nbsp; n + " are:");
17
18&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // We build sumOfDivisors[i] to hold a string expression for
19&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // the sum of the divisors of i, excluding i itself.
20&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; var sumOfDivisors = new ExprArray(n+1,1);
21&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (var divisor = 2; divisor &lt;= n; divisor++) {
22&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (var j = divisor + divisor; j &lt;= n; j += divisor) {
23&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; sumOfDivisors[j] += " + " + divisor;
24&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
25&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // At this point everything up to 'divisor' has its sumOfDivisors
26&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // expression calculated, so we can determine whether it's perfect
27&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // already by evaluating.
28&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (eval(sumOfDivisors[divisor]) == divisor) {
29&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("" + divisor + " = " + sumOfDivisors[divisor]);
30&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
31&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
32&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; delete sumOfDivisors;
33&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("That's all.");
34&nbsp;&nbsp; }</tt></pre>
The line number to PC and back mappings can be tested using the js program
with the following script:
<pre><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; load("perfect.js")
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print(perfect)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; dis(perfect)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print()
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (var ln = 0; ln &lt;= 40; ln++) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; var pc = line2pc(perfect,ln)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; var ln2 = pc2line(perfect,pc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; print("\tline " + ln + " => pc " + pc + " => line " + ln2)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }</tt></pre>
The result of the for loop over lines 0 to 40 inclusive is:
<pre><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; line 0 => pc 0 => line 16
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; line 1 => pc 0 => line 16
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; line 2 => pc 0 => line 16

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; line 40 => pc 172 => line 33</tt></pre>
</ul>
<h4>
jsconfig.h</h4>
Various configuration macros defined as 0 or 1 depending on how <tt>JS_VERSION</tt>
is defined (as 10 for JavaScript 1.0, 11 for JavaScript 1.1, etc.). Not
all macros are tested around related code yet. In particular, JS 1.0 support
is missing from JSRef. JS 1.2 support will appear in a future JSRef release.
<br>&nbsp;
<h4>
js.c</h4>
The "JS shell", a simple interpreter program that uses the JS API and more
than a few internal interfaces (some of these internal interfaces could
be replaced by <tt>jsapi.h</tt> calls). The js program built from this
source provides a test vehicle for evaluating scripts and calling functions,
trying out new debugger primitives, etc.
<h4>
jsarray.*, jsbool.*, jdsdate.*, jsfun.*, jsmath.*, jsnum.*, jsstr.*</h4>
These file pairs implement the standard classes and (where they exist)
their underlying primitive types. They have similar structure, generally
starting with class definitions and continuing with internal constructors,
finalizers, and helper functions.
<h4>
jsobj.*, jsscope.*</h4>
These two pairs declare and implement the JS object system. All of the
following happen here:
<ul>
<li>
creating objects by class and prototype, and finalizing objects;</li>
<li>
defining, looking up, getting, setting, and deleting properties;</li>
<li>
creating and destroying properties and binding names to them.</li>
</ul>
The details of an object map (scope) are mostly hidden in <tt>jsscope.[ch]</tt>,
where scopes start out as linked lists of symbols, and grow after some
threshold into PR hash tables.
<h4>
jsatom.c, jsatom.h</h4>
The atom manager. Contains well-known string constants, their atoms, the
global atom hash table and related state, the js_Atomize() function that
turns a counted string of bytes into an atom, and literal pool (<tt>JSAtomMap</tt>)
methods.
<h4>
jsgc.c, jsgc.h</h4>
[TBD]
<h4>
jsinterp.*, jscntxt.*</h4>
The bytecode interpreter, and related functions such as Call and AllocStack,
live in <i>jsinterp.c</i>. The JSContext constructor and destructor are
factored out into <i>jscntxt.c</i> for minimal linking when the compiler
part of JS is split from the interpreter part into a separate program.
<h4>
jsemit.*, jsopcode.tbl, jsopcode.*, jsparse.*, jsscan.*, jsscript.*</h4>
Compiler and decompiler modules. The <i>jsopcode.tbl</i> file is a C preprocessor
source that defines almost everything there is to know about JS bytecodes.
See its major comment for how to use it. For now, a debugger will use it
and its dependents such as <i>jsopcode.h</i> directly, but over time we
intend to extend <i>jsdbgapi.h</i> to hide uninteresting details and provide
conveniences. The code generator is split across paragraphs of code in
<i>jsparse.c</i>,
and the utility methods called on <tt>JSCodeGenerator</tt> appear in <i>jsemit.c</i>.
Source notes generated by <i>jsparse.c</i> and
<i>jsemit.c</i> are used
in <i>jsscript.c</i> to map line number to program counter and back.
<h4>
jstypes.h, jslog2.c</h4>
Fundamental representation types and utility macros. This file alone among
all .h files in JSRef must be included first by .c files. It is not nested
in .h files, as other prerequisite .h files generally are, since it is
also a direct dependency of most .c files and would be over-included if
nested in addition to being directly included. The one "not-quite-a-macro
macro" is the <tt>JS_CeilingLog2()</tt> function in <i>jslog2.c</i>.
<h4>
jsarena.c, jsarena.h</h4>
Last-In-First-Out allocation macros that amortize malloc costs and allow
for en-masse freeing. See the paper mentioned in prarena.h's major comment.
<h4>
jsutil.c, jsutil.h</h4>
The <tt>JS_ASSERT</tt> macro is used throughout JSRef source as a proof
device to make invariants and preconditions clear to the reader, and to
hold the line during maintenance and evolution against regressions or violations
of assumptions that it would be too expensive to test unconditionally at
run-time. Certain assertions are followed by run-time tests that cope with
assertion failure, but only where I'm too smart or paranoid to believe
the assertion will never fail...
<h4>
jsclist.h</h4>
Doubly-linked circular list struct and macros.
<h4>
jscpucfg.c</h4>
This standalone program generates <i>jscpucfg.h</i>, a header file containing
bytes per word and other constants that depend on CPU architecture and
C compiler type model. It tries to discover most of these constants by
running its own experiments on the build host, so if you are cross-compiling,
beware.
<h4>
prdtoa.c, prdtoa.h</h4>
David Gay's portable double-precision floating point to string conversion
code, with Permission To Use notice included.
<h4>
prhash.c, prhash.h</h4>
Portable, extensible hash tables. These use multiplicative hash for strength
reduction over division hash, yet with very good key distribution over
power of two table sizes. Collisions resolve via chaining, so each entry
burns a malloc and can fragment the heap.
<h4>
prlong.c, prlong.h</h4>
64-bit integer emulation, and compatible macros that use C's long long
type where it exists (my last company mapped long long to a 128-bit type,
but no real architecture does 128-bit ints yet).
<h4>
jsosdep.h</h4>
Annoying OS dependencies rationalized into a few "feature-test" macros
such as <tt>JS_HAVE_LONG_LONG</tt>.
<h4>
jsprf.*</h4>
Portable, buffer-overrun-resistant sprintf and friends. For no good reason
save lack of time, the %e, %f, and %g formats cause your system's native
sprintf, rather than <tt>JS_dtoa()</tt>, to be used. This bug doesn't affect
JSRef, because it uses its own <tt>JS_dtoa()</tt> call in <i>jsnum.c</i>
to convert from double to string, but it's a bug that we'll fix later,
and one you should be aware of if you intend to use a <tt>JS_*printf()</tt>&nbsp;
function with your own floating type arguments - various vendor sprintf's
mishandle NaN, +/-Inf, and some even print normal floating values inaccurately.
<h4>
prmjtime.c, prmjtime.h</h4>
Time functions. These interfaces are named in a way that makes local vs.
universal time confusion likely. Caveat emptor, and we're working on it.
To make matters worse, Java (and therefore JavaScript) uses "local" time
numbers (offsets from the epoch) in its Date class.
