Maxim 11-Feb-2007 [7115x4] | my god... REBOL is going nuts! I have a situation where the above is not true... and the select pairs are [aword an-object bword another-object] |
and only the find works... if I try to select using 'aword it always returns none | |
print first reduce blk raises an error as expected since aword is not defined anywhere! | |
help! this is tooo strange! | |
Anton 11-Feb-2007 [7119x2] | relax... rebol is probably not going nuts. There is a reason somewhere. |
quickly make a little example file which demonstrates the problem using a new console. | |
Maxim 11-Feb-2007 [7121x3] | hehe... its just that no probing or printing reveals anything out of the expected. |
using a new console, things behave as expected... which is why I am wondering why they don't in the running code | |
(using a block with simple values, the two lines above act as I would expect) | |
Anton 11-Feb-2007 [7124] | Ok, then fork the entire code and cut away chunks until it no longer displays the problem. |
Maxim 11-Feb-2007 [7125x2] | ehh impossible... we are talking bout an entire app here... 200-300kb of code. probably... and the problem occurs within an event loop. |
but look at the simplicity of the two lines above... can you image a way in which the select would return none and the find would return the object? | |
Anton 11-Feb-2007 [7127x2] | (not impossible - that technique works when I can think of nothing else). |
A confusion between lit-words and words maybe ? | |
Maxim 11-Feb-2007 [7129x2] | hum... |
unfortunatetely, I can't print the block, cause the objects have nested objects, and that causes an out of memory err, If I try to mold it :-( | |
Anton 11-Feb-2007 [7131x2] | write clipboard:// mold/all blk and paste it (and mold/all VAL) into a new editor window. |
Ah.. | |
Maxim 11-Feb-2007 [7133] | the actual app takes very little ram, but the objects, have bidirectional linking... so I guess the mold never reaches the end. |
Anton 11-Feb-2007 [7134] | Ok, then, for your test, before molding, process each object to set none all fields which could recurse. |
Maxim 11-Feb-2007 [7135x4] | hum... I'll try my inspector... maybe it can help me a bit... |
oops... closed altme by mistake... the inspector basically has the same problem... | |
I'm trying some block alterations... | |
wrt lit-word vs word... find is reacting as expected.... select is numb like a frog on ice | |
Anton 11-Feb-2007 [7139] | Maybe check that BLK really has the expected types in the correct order. |
Maxim 11-Feb-2007 [7140x6] | oh my... I just found it... same? :select get in system/words 'select == false |
seems some code redefines select somewhere... >:-( | |
well, thanks for bearing with me... your words vs lit-words idea... got me probing differently.. | |
strangely, I can't trace where that is happeneing... willl try to protect the word... | |
well, as usually protect doesn't help... arrgh. | |
(as usuall) | |
Anton 11-Feb-2007 [7146] | protect doesn't help ? Is SELECT redefined despite being protected ? |
Maxim 11-Feb-2007 [7147x5] | well, protect, only helps within the global context... which is why I wish there was /HARD mode which protected ANY setup of a specific word. |
probably also can protect word within a context... but at that point, the damage is usually done. | |
I've discoverd another way to discover where a set occurs... within objects, you look at the first... and the natural order of words, is a telling clue... | |
first self | |
well found it... and its a biggie :-( deep within glayout... well... its actually pretty easy for fix there, though. | |
Maxim 12-Feb-2007 [7152] | why the hell did I use select... its actually quite strange that this is the first time I've hit this snag in 3 years though ! |
Anton 12-Feb-2007 [7153x2] | I should just point out that only the system/words object can grow dynamically. |
Other objects have fixed order of words. | |
Maxim 12-Feb-2007 [7155] | the issue is that as it is a commonly used feature, although easy to fix within glayout... many references to in my apps will break... ahh... |
Anton 12-Feb-2007 [7156] | The order does not change after the initial SET. |
Maxim 12-Feb-2007 [7157] | yes. |
Anton 12-Feb-2007 [7158] | >> set 'var-1 1 == 1 >> set 'var-2 2 == 2 >> set 'var-1 3 == 3 >> print mold skip tail first system/words -4 [Comments in-obj var-1 var-2] |
Maxim 12-Feb-2007 [7159x4] | how the hell did I not realise I was overiding such a core word? sometimes the obvious just slips by... when you're looking the other way ' :-/ |
yes anton, which is why I discovered where it was being set... after a func called 'layout (this one voluntarily being an override) | |
It would be nice in R3 if we could remove things from an object when deriving with make... (we can , sort of, using the 'THIRD accessor on an object and editing it....) | |
but when the object is being created by another controler (like in view) then we can't really... | |
PeterWood 12-Feb-2007 [7163] | So you'd really like Rebol to have the equivalent of JavaScript's Delete operator? |
Maxim 12-Feb-2007 [7164] | hum don't know about it... but if I could do obj: make/without ref-obj [] [select] We could already shrink our objects, when its needed. |
