- append option was renamed to partial and it login changed: we must mark class as partial for allow their modifications in future.

- opcodes were moved to separate namespace

- characters '@' and '#' now can be escaped by '^'

- error message was changed

- stuff for @OPTIONS\nappend

- bugfix in 'def' compilation: ^if(default){true. it's incorrect. must be exception}

- compile return list of classes now. internals.

- changes in compiler: @OPTION\nlocals + @method[vars][;locals;] were added

- bug if parser.compile error occure in unhandled_exception finally fixed

- if error occure while compile method don't put this method in methods table anymore.
in other case the parser coredumped if @unhandled_exception method can't be compiled because of parser.compile error.

version

. win32: grammar is now compiled with bison 1.875b, it reports unexpected token names

! bugfix xnode now holds a link to xmlNode to prevent premature gc(xmlNode)

merged from HEAD
! fixed overoptimized ^call(false) case. (confused it with ^call[] case)

merged from HEAD
! fixed overoptimized ^call(false) case. (confused it with ^call[] case)

! fixed overoptimized ^call(false) case. (confused it with ^call[] case)

. started killing gdome

. less warnings

. version readded

makefiles

Makefile

! overoptimized void literals, reverted to just vvod, recreating empty array with each void_value token. that's absolutely needed, since that array grows

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

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

! fixed file load memory issue: now tries to guess content-length and allocates one big piece if possible [regretfully gc_realloc works as malloc+free, leaving lots of holes behind]

merged to HEAD:
! table::save with enclosers now doubles them: "->""
! table::save/load do not remove elements from options hash

! ^if(-f "...") now works [were overoptimized ^if(double_literal), compiler confused OP_VALUE+origin+double with OP_STRINGPOOL+code+OP_writeXX

removed $< from .y compilation, not all makefiles liked that

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

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

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

+ optimized constants in expressions vstring->vdouble

started:
	^void:sql{call paf(:a)}[
		$.bind[
			$.a[2]
		]
	]
input variables work.
todo:output

bugfix: bcc with sendmail now left intact

bugfix: gcc refused to accept that trick, trying other

bugfix: step3 to fix explicit result problem

bugfix: step2 to fix explicit result problem

bugfix: step1 to fix explicit result problem

attempt_check_call_in_explicit_result_mode: failed

reimplemented: @method[][result] means "no string output here"
moved to lexical level [on grammar level it were too difficult]

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

change: .xsl.stamp now not used, introducing dependencies timestamp check

started changes to reflect libxml xsl new folders

*** empty log message ***

turned on warnings level4 on all projects (except libltdl=off & libsdbm=level3)
found several unitialized vars

hashfile: started again with sdbm from apache

CORD_chr does not check offset argument for validity
did that in String::Body::pos myself
http://i2/tasks/edit/?id=4577425257580789777

^if ( better error:
.html(1:4): parse error, expecting `'['' or `'{'' or `'(''  now

string_fragments_to_cord merged to HEAD

string: debug: .v() functions aligned to that of eeparser3 look

$date.TZ
^date.roll[TZ;new zone]

no message

initialized couple of variables about which user reported runtime problems when parser were compiled with VC7, warning level4.
study shows that later in bison they've fixed that. would migrate to latest bison someday

merged 3.1.0 latest changes

no message

moved tempate_gc to HEAD

moved tempate_gc to HEAD

  line number (max: 64535)
  column number (max: 255)

$hash.fields -- pseudo field to make 'hash' more like 'table'

lib/libltdl -> lib/ltdl Win32 changes. s

static fix merged

killed $virtual_fields in dynamic, but one can reach derived  static[class] variable from base

lexer changed to fix ^call[]^#HH bug [that situation yelded no EON, which whas wrong]

operators precedence changed a little:
logical not and bitwise negation precedence made highest,
<< and >> bitshits precedence made equal [were << higher than >>]

removed last pieces of old code allowing $junction.xxx at compile time

process[self] objects also considered [were only classes]

^for[i](1;10){
	$code.key($i)
	$code.value($i*2)

)

(expression #comment with (brackets) comment) << OK

!| bitwise
!|| numerical
xor now
[preparing for expression #comments]

@method[$name]
now parse error

cookie date now clean [were mistakenly tainted & that worked bad with opera -- 'happily' that worked OK with msie]

# now delimiter

"BASE:"
"BASE::"
syntax allowed, means "base class".
compiled as if here they named base class

VObject.get/out now looking down/up tree
todo: fix error message on non-constructed parents

^base:create[] dynamic call rewritten
todo: thorough testing

$Date: now$

moved libltdl and pcre to libs/
added libs/md5 which is linked to non-apache targets
^math:crypt[password;$apr1$salt]

parser3.conf now one and only

whitespace after number in autoconvert now ignored

fixed .dsp-s along with reorganized cvs modules dirs structure

reorganized cvs modules

main_method_name now on Request pool rather on global_pool [Junction+VJunction created on same pool as name = were created on global pool, causing mem leaks]

Table name2number field now &.
main_method_name now on Request pool rather on global_pool [Junction+VJunction created on same pool as name = were created on global pool, causing mem leaks]

MSVC profile targets

OP_GET_METHOD_FRAME merged with OP_CALL, VCodeFrame move to stack [no more heap waste on each CALL]

cheched date:create(days) param for validity [later were assumed valid and crashed on invalid onces]

OP_CALL -> OP_CALL__WRITE and used that for removing VString wrapper

OP_GET_ELEMENT+OP_GET_ELEMENT__WRITE
changed to OP_WRITE_VALUE
in var get cases

switch in hash constructor fixed [were problems with using of stacked wwrapper after it's death]

removed
{
  char *a;
  {
     /*sub local*/char b[...];
     a=b;
situations

*.dsp: removed refereces to win32db & ancient xalan&xml

strign to string append optimiziation idea and estimates

in_expression
aimed to solve old problem with string/nonstring values,
now in expressions double/int values are passed as-is, without stupid tostring/fromstring conversions

bison env set so one could compile without cygwin installed

integer  division stops name

2002

disabled $if reference due to conflicts with local variables

^int/double/string.format
now can be called with normal [] brackets, not stupid {} as it were implemented for some strange reason.
retaining backward compatibility due to some already-implemented servers

operators now detected by check at name_without_curly_rdive_read rule whether diving code constists only of
OP_VALUE+string+OP_GET_ELEMENT.
and last op code substituted with OP_GET_ELEMENT_OR_OPERATOR
to form
OP_VALUE+string+OP_GET_ELEMENT_OR_OPERATOR.
code

rewritten ^cache to use non-blocking-exclusive-caches

disabled operator call after ^xxx:

made operators lookup first in ^xxx situation.
so that one could not do
$if[1]
^if[xxx]

operators check 6.1
rewritten. now check is done at compile time

operators check 4
floated up old error of staying in 'entered object' state after ^a.a(a)
it prevented operators from being called thereafter

#comment  before @ after @SPECIAL
now works OK

typedef XMLCh... not stupid illegal define

merged from r17 - hashfile without logfiles

hashfile:
removed use of transactions
[libdb removed DB_INIT_LOCK, DB_INIT_LOG, DB_INIT_TXN init bits,
thus got rid of huge log files, which cluttered disk without huge need]

removed exception va_list constructor.
1. not needed anymore
2. there were a conflict[causing errors] between
ctor(, va_list)
ctor(, ...)
compiler[both msvc and gcc] never detected an ambiguilty here, compiling
ctor(, "hello") into ctor(, va_list) which, of course, caused gpf

partial logical && || evaluation

gnome libs just compiled in.
no refcounting
no xpath
no xslt
  yet

removed debug info

$status:db
fixed used not initialized in db_connection & db_table

\ in expression: int divide 10/3=3

@next_method  << now unclosed ] would be reported here

^a[^b] more informative compile error

parsedSource produced by nonstandard liaison freed up

restored project

xdoc.transform now

disabled ^literals in names
$result[^[$p^]z]
now works fine

xdoc&xnode now

merged3 with before_xml
[merge2 actually didn't happen - i've created tags on wrong branch. so this merge is in fact re-merge]

merged with before_xml

merged latest bugfixes from before_xml branch
^if(def $hash) now true only when ^hash:_count[]!=0
moved
.string .save .file from dom to dnode

expressions unary+
^hash.count[]
bugfix: in expression compound($aa.zz.xx) names now can have minus '-' in name after '.'

bug fixed [thanks, fif], ^; were treated there non-literally

strncpy forced with zero ending in case of limit

file:load|save[text|binary;

^method[]^[^] literals []

$var(123) ^var.inc[] recousively caused problems: inc incremeted 123 literal!! fixed

[codes] name part syntax now
