2005

. 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: just compiled

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

. steps toward removing ALL_INTERIOR_POINTERS

+ operator ^sleep(double seconds)

+ operator ^sleep(double seconds)

bugfix: cache with 2 params caused assertion, checked that

beauty: removed outdated level 'table'

bugfix: junction reattach now actually reattaches a junction to new wcontext [were only assigning it to junction,
which caused junction tracking to loose junction, and it's context were not killed, and it tried to process in invalid context, gpf]

feature: ^process...{CODE}[now has options]
which are
        $.main[to what to rename @main]

cache: ^cache[] fallback
todo: kinda ^try:  ^cache[...]{body}{catch code with $exception.cache field}

just linked

bugfix: ^throw context were saved/restored incompletely
http://www.parser.ru/forum/?id=21484

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

^process...[filename]
useful for better error reporting  [file/line/col]

exception handling done. now we have error columns
todo: test it

removed from trace 'a' exception when
^try{
   ^throw[a;1]
}{
   ^throw[b;2]
}

this makes life easier: were: bad stack order -- were in exception catch unwind order, which didn't match execution order


@main[]
^try{
	^first[]
}{
	^throw[c;3]
}

@first[]
^throw[a;1]

showed
throw a
first
throw b
try

which is no good

Request::get_self() mapped to VMethodFrame.self()

VMainClass now has name = $hash in open field now gives old good error meesage

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

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

^process[$caller.CLASS]{code-string} added

removed $junction.get $junction.set[]
introducing $caller

process compiles to code's class class

operators now main-class-methods

^try{^call{}} now has better stack trace [has "call" & co there]

pa_request contexts made privated, plus get_{self/method_frame} to read.
Request_context_saver used in ^try to save flang too.
[were not saved]

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

made place for ^process to compile it's code to in case of no self

menu/for delims bug fixed [were ,2,3]

VCodeFrame parent param were specified badly

moved junction kill responsibility to wcontext

sql connection with error were put to cache with 'marked_to_rollback' flag, all consequent even OK requests rolled back

introducing ^try

process body now evaluated in PASS language

string deserialize checks on broken file

name spelling

2002

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

file_write does EX lock after create,
while file_read does SH after open,

added a check for that in ^cache...read

removed redundant pool param to some pa_common funcs

auto closers to sql_connection, stylesheet_connection
