inline-storage hash used to avoid allocations for MethodFrame args and locals (imlpements feature #1293)
_stack uses for_each to avoid Iterator for InlineHashString

feature #1273 core implementation: value::as_wint added, implemented for int/double/string, and used where applicable; vint now holds pa_wint type; format_double moved to pa_int

implements feature #1277
String::Body(const char *abody) now explicit
but HashString::put(const char *str, V value) added for simplicity
optimizations:
HASH_PUT_CSTR used where hash.put called several time during execution;
caching String::Body::uitoa used at all pash.put(<uint> calls.

warning war

even better error reporing for params.as_* (related to feature #1267)

better error reporing for params.as_string (implements feature #1267)

some file methods now accept file as path specification (adopted Sumo patch implements feature #1265)

detailed result_optimization comments (related to feature #1266)

my.set -> set_my_variable in preparation for $result optimization (related to feature #1266)

extra_params and named params should be also inited in ^method[] call (related to feature #1205)

Copyright year updated

optimization: PUT_ELEMENT_REPLACED_ELEMENT no longer used in object-prototype mode

Copyright year: 2015->2017

^reflection:stack[] added (implements feature #1052)

comment added: params should be declared outside of *_FRAME_ACTION as MethodParams destructor will be called in ~VNativeMethodFrame

Copyright year updated

removed most of the clang compiler warnings (closes issue #1018)

- $var.CLASS & $var.CLASS_NAME now have special opcodes. This can be switched off by commenting #define OPTIMIZE_BYTECODE_GET_ELEMENT__SPECIAL on pa_opcode.h ( new feature: #844 )

GPF if method junctions is passed to native method fixed (closes issue #942)

optimization: put_element no longer has "bool areplace" argument, related to issue #903

- MethodParams::as_table is added
- above methods are used for parsing methods' options ( new feature: #9 )

bug #782 fixed

feature #154 - first empty param now string; defined locals are empty strings; $STRICT-VARS(true) added

ident now works under Linux + ident displays filenames (closes issue #818)
Copyright updated

closes #26: variable number of params can now be passed to a method declared with *arg

- helper method as_hash was added

optimization:
VMethodFrame(junction, caller) replaced with VMethodFrame(method, caller, self)
op_call(VMethodFrame &frame, bool constructing) removed, construct(class,method) added

- bugfix: the actual number of method's parameters wasn't checked correctly (the bug was introduced in 3.4.0)

- optimization

- new classes implementation

- hash now keeps order of elements

- changed in destructing junctions

- hash_code caching was implemented (seaches should be faster now)

- bugfix: taint/untaint didn't work with OPTIMIZE_RESULT

- result optimisation
- helper_length parameter removed from string constructors

- changes in stack impl
- get_element() optimisation: 3rd param removed
- bugfix: problems with reading empty input param
- defines SAVE_CONTEXT and RESTORE_CONTEXT were added and used

- we can work without opcode OP_STORE_PARAM, so it was removed

- destructors under #ifdef now

- destructors were added

- write_to_result renamed to always_use_result

- set flag write_to_result if find result in var's hash

- optimisation in method_frame

- if flag write_to_result was set, not needed to check existance var with name 'result' in var's hash

- create new String only before 1st write

- fresult_initial_void removed + some optimisation
- if $result defined we don't write to context anymore

- VVoid::get() => new VVoid (one void-instance)

- still need to check 'self' runtime as well (for $caller.self)

- looking for caller before looking for vars

- ALL_VARS_LOCAL_NAME moved fo compile.y

- go back to one VMethodFrame with internal switch between local/global vars

- who children for VMethodFrame were added: one (global) works as VMethodFrame before and second (local) write all vars in self vars scope

- method as_expression was added

- "parser.runtime" strings were removed

+ merged: expression literals: true/false. ^format[$.indent(true)]

+ expression literals: true/false. ^format[$.indent(true)]

merged ! many classes/*  used as_junction where they needed as_int/double, so failed with recent "(const) now no junction" optimization

! many classes/*  used as_junction where they needed as_int/double, so failed with recent "(const) now no junction" optimization

2005

merged from HEAD ! simplified (double) speedup consequent checks in vmethod_frame

+ ^call[$void] param inside now is void (were: empty string)
! simplified (double) speedup consequent checks in vmethod_frame

merged
+ optimized constants in expressions vstring->vdouble
+ optimized ^call(vdouble), no junction creation, no calls later

. merged VJunction(new Junction) optimization from 3.1.4

+ optimized ^call(vdouble), no junction creation, no calls later

. 2005 ;)

+ 3.2.0 beta: merged from dynamic_fields_join

! restored put_element('replace' param), and restored its checks in vobject.put_element->static fields | dynamic properties

joined_dynamic_fields: removed unused param from put_method (returned to 3 params)

joined_dynamic_fields: just compiled

. properties: set works [alpha1]

+ started property [getters work but think of changing them too to precaching]

bugfix: when method junction was created by accessing $name_of_method it acquired bad self=closest methodframe; instead of proper self (current class)

new: @method[][result] means "no string output here",
implemented part of that idea: compiler throws away string literal generation code. and barks nonwhitespace chars

2004

more warnings --

static const char * const IDENT

moved tempate_gc to HEAD

MethodParams& now [methods without params receive zero reference, but they are expected not to look there]

removed changes, operators executed with calling self.
lots of code with ^include code relies on defined/defining self variables

$a[1]
^include[print_a.p]
print_a.p: $a

^include[set_a.p]
a=$a
set_a.p:
$a[1]

operators now executed with MAIN self.
it's for ^include sake, too strong a change

allowed Request.self to be 0, checked that in VMethodFrame get/put and $self.

is now works with VObject & VClass

introduced Value::get_element(..., bool looking_down) [needed to exclude endless recoursion]

$Date: now$

ident.C* removed

marged latest HEAD updates, mainly file:justname&co & @auto/conf[filespec

introducing @conf/auto[filespec]

$result[] now gets properly analized

fixing :: realization #1

introducing ::
this is constructor call prefix.
ordinary : remains for static accesses

nothing renamed to void

'unknown' renamed to 'nothing'

'unknown' renamed to 'nothing'
