Re: [binarycloud-dev] Still Something Rotten....

[Odysseas T. <ody...@ya...>]

But you were right that the rest of the code
isn't behaving the way it was supposed to :-)

I needed to add a ksort right before the end of the
IncludeModules function

        ksort($this->modules[$_group]);

Keep in mind that the the "example" layout that
index.php comes with is not following the
default order but it explicitly alters it.

Thanks for the bug,

odysseas

Re: [binarycloud-dev] Still Something Rotten....

[Odysseas T. <ody...@ya...>]

The sorting works as expected.

Array order and key-value association are two 
different things in php.  
uasort doesnot change the key association, i.e., you
should not see a 0 indexed element if you didn't
original create one with that key.

Check the *sort man pages for more info.

=================================================
Alex:

Oy weh.  Now I was var_dump()'ing what you have above, viz:

var_dump($Page->modules['top'][0]);

as I thought that was it after looking at Page.php, and all I
was getting were NULL's.  Of course, of course, I was
in some decendant class method, and forgot to global $Page
within the method......

But, Alex, you are not going to make us use this syntax,
are you?  No, you are figuring out something with a
bit more elegance, aren't you? :)

There is _still_ something rotten, at least it seems so,
in your array sort in Page.  This load_order thingy
has, you realize, the weakness, that you can put in
index.php three modules in a 'top' group with load_order(s)
as:

EXAMPLE---

MOD1	load_order=>69
MOD2	load_order=>22
MOD3	load_order=>11

and this _should_ map/sort to

$Page->modules['top'][0]	===> MOD3
$Page->modules['top'][1]	===> MOD2
$Page->modules['top'][2]	===> MOD1

but it doesn't.  No matter what you put in your
load order, the sequence in $Page->modules['top']
is ALWAYS IN THE ORDER OF the appearance in index.php.
Anyway, it appears your uasort() thingy is not working,
and that, specifically, your sorting comparison function:

create_function('$a,$b', 'return $a("load_order"]
			- $b["load_order"];');

must be always returning 0, instead of (-1,0,+1) accordingly.

Now I am wondering, with your sorting, IF IT WERE WORKING,
you have it mechanized, I think, that for my EXAMPLE above,
admittedly wrong or sloppy, it would create a sparse array
if the load_order was a number type and not a number_string (with
quotes).
I think you also need to guard against sparse arrays somehow.
Well, I haven't tried to "fix" _IncludeModules($_group)
and see if it does create a sparse array....

OK Alex, so in any case, you are going to figure out some
kind of way to reference _which_ instance of multiple
loads of the same module easily.  The only thing that
occurs to me quickly is something like adding a tag,
as in:

                array(
                        'name'          => "EyeLibrary",
                        'package'       => "lib",
                        'load_order'    => 2,
                        'tag'           => "TableData",
                        'options'       => "option1",
                ),

and then allow reference to that particular module as:

$Page->modules['top']['TableData']->method_or_property;

That is knee-jerk, but gives you something to think about.

[binarycloud-dev] Which files to change / work on?

[Jimmy H. <ji...@ha...>]

Hi after finally having a win on my freebsd make system, now I move on
to the more exciting part....

Under r2/binarycloud/ there are
base
build
ext
user


Which one should I work on and which one should I not touch?
Any hint for *first* time *newbie* on what to do to create a page,
template, and an admin area? How about database connection etc? Where do
I go?

Thanks for the hints.

Regards,
Jimmy

Re: [binarycloud-dev] var naming

I am in favor of this.  Like you said, simply for continuity.

[binarycloud-dev] var naming

[alex b. <en...@tu...>]

hi all,

on monday I'll be changing some important variable names, if you look at the
global var space now, it contains:

sImportMap <-- static, global var used by import (thus the (sName))
gImportPaths <-- global var used by import for paths
bc_page <-- page declaration (note the discontinuity between this and
gImportMap)
Init <-- Class
Timer
Debug
Sess
bc_lang
bc_lang_name
bc_lang_datespec
bc_lang_timespec
Lang
_lang
bc_lang_charset
bc_lang_currency_name
bc_lang_currency_symbol
Err
Page
_tmpl <-- "external" user-space variable that is significant to the system.

-------

It will contain, instead:

Static, globals vars of the form sVarName:
sImportMap

Global Vars of the form gVarName:
gImportPaths
gPageDef <-- this is what $bc_page will become.
gLangCode <-- formerly $bc_lang
gLangName <-- formerly $bc_lang_name
gLangDateSpec <-- formerly $bc_lang_datespec
gLangTimeSpec <-- formerly $bc_lang_timespec
gLangCharset <-- formerly $bc_lang_charset
gLangCurrencyName <-- formerly $bc_lang_currency_name
gLangCurrencySymbol <-- formerly $bc_lang_currency_symbol

Class names:
Init
Timer
Debug
Sess
Lang
Err
Page

External, user-space vars:
_lang
_tmpl

At the moment, we haven't integrated Request into the page render process.
Once that is done, the system will assume that register_globals is _OFF_ and
act accordingly. (I will probably have init check the ini setting and send a
warning message to Debug if it is on.)

I will update the standards when I am done, but here are the rest:

Class names:
ClassName, must be contained by ClassName.php, one class per file.

Public Methods & Constructor:
PublicMethod

Private Methods:
_PrivateMethod (this is a change for continuity)

Class Vars:
varname

I have not defined public/private class vars as php doesn't support them -
is anyone in favor of making an artificial distinctoin similar to the
private class names?

like:
Private Class Vars:
_varname

--------

time for sleep :)

Re: [binarycloud-dev] CVS

[alex b. <en...@tu...>]

hi ronald,

you are correct, before we were using package declarations, but now it's
implicit. (I forgot :)

I've removed the package declaration in my core cvs, I'll push that in with
the next synch.
There's some other foo going on with libs that I'm working on now.

Re: [binarycloud-dev] CVS

[Odysseas T. <ody...@ya...>]

Yes, you are right. 
The package declaration inside the XSLT_Example.php
doesn't make sense. 
It must have got there by mistake.
If you remove it (cvs will soon reflect the fixed up 
file) things should be fine.

$Page->modules['group_name'][load_order]->variable_name

Thus my mention of possibly using unique names in the page declaration, so
making references to modules would be more simple.

that would also complicate the page module sorting functions, so I'm not
sure it's worth doing that way. it may be a lot more simple to have a module
communication manager which is called by a module that needs something, like
a really simple Request class.

[binarycloud-dev] Module Communication - Total Confusion

[Justin F. <je...@ey...>]

Alex:

Sometimes my mind just falls apart, and I feel like I am in that
state right now.  In one of your last posts, you suggested to
get a large/complex bit of data and store it in a class variable,
and then (implied) down the load chain, this variable can
be accessed.

HOW?

Especially, what if I want something from a module in a group
when they are two instances, but do different things because
of passed in options.

EXAMPLE stanza / module group top
    'modules' => array(             
            'top' => array(         
                    'load'  => array(
                            array(
                                    'name'          => "EyeLibrary",
                                    'package'       => "lib",
                                    'load_order'    => "1",
                                    'options'       => "option1",
                            ),
                            array(  
                                    'name'          => "EyeLibrary",
                                    'package'       => "lib",
                                    'load_order'    => "2",
                                    'options'       => "option2",
                            ),
                            array(          
                                    'name'          => "Blank",
                                    'package'       => "lib",
                                    'load_order'    => "3"
                            ),      
                    ),              
            ),                      
----------
Now in the above stanza, EyeLibrary that has load order "1"
does something as dictated
by option1, and stores that data at, say, $this->what_i_need.

EyeLibrary that has load order "2" does something as dictated
by option2, and stores that data at, say, $this->what_i_need.

NOW, how the hell do I get the data EyeLibrary[0]->what_i_need?
NOW, how the hell do I get the data EyeLibrary[1]->what_i_need?
Both of these pieces of data are desired in Blank, load order
"3".

If I instantiate a new EyeLibrary within a following module,
this is no good at all, because I have in the constructor
something like:

        function EyeLibrary($_options="ain't no options in EyeLibrary")
{
                $this->options  = $_options;
		some other code, maybe
                return true;
        }

so all I would get was "ain't no options...", which, for the example,
is EyeLibrary->what_i_need.

How do I do this without going global????

You instantiate the thing in $Page->_IncludeModules() with the
options from $bc_page, but how do I get to that instantiation, and
distinguish
between the two loads????  WITHOUT GOING GLOBAL SCOPE
in the constructor???

My mind is mush right now...

this is just because there is a package declaration inside
r2/binarycloud/user/mod/xslt_example/XSLT_Example.php that I haven't seen 
it
in other module example, by removing the package declaration you can get 
the
right things.....
but alex is it necessary to put the package declaration inside the module??
I think so, but the make system seem to be do something wrong with this, 
and
at the same time, the other example modules do not have the package 
declaration.

[=======================]

This is true, it is something else that I have "wondered" about,
namely I already "use" multiple loads of the same module, even
if it is a place holder called Blank.php.  I wondered if name
mapping was possible, but I am always asking...

I really find programming with BC a, er, what, paradigm change
in thinking.  The nice problem with BC is, you are smothered with
a plethora of riches, you can do things in several different
ways, but you wish to retain generality, and all that good
stuff.  It is taking me some time to "feel" how to adjust
things like module granularity, module functionality.  Like
do you create "thin" lookup tables, do you break out that
huge data structure previously referred to as a module
in itself, ad infinitum.

But, it is fun.  BC is a cafeteria with 52 kinds of cheesecake...
I hope we discover as early as possible what we really "need".
This does not imply that BC is bloated, on the contrary.

Again, good job, Alex.

Right. But you have fairly little to worry about there, this is PHP after

Right, because you are doing a _huge_ amount of "discovery" for every
action, which seems unnecessary.

That will screw you re: performance.

You should be using it by reference (=&) to avoid creating a copy of the
object. That's memory intensive as hell :)

You should make your "discovery" data available in a var of the class so
other modules can ask it questions.

I'm thinking we probably need to (unfortunately) allow for unique names in
module declaration arrays, so modules can refer to each other simply.

Right, but it isn't specifically a result of not using Init anymore. You
should be putting that stuff in a var in your module, which other modules
can "see".

I have considered that, and I still can't quite justify it. You can do all
of that talking-between-modules stuff with a combination of load order and
well designed class variable structures in the modules.

> Yes, I do respect Alex's "law" that he wants globals to be held to

Try and put your data in a class var in the module that gets the stuff from
mysql, then have your other module(s) get that class var.

The reason I mentioned the naming thing above is because we instantiate
modules inside Page->modules[position_in_load_order] - so you'd be using the
load order which is page specific (i.e. that won't work well at all)

I can see potentially wanting to add the "unique name" concept to
$bc_page['modules']['group'][x] because you might want to have the ability
to address modules individually (even if there are multiple instances of a
module on a page.

That last thing needs quite a bit of thoght, because it can cause problems:
    -unnecessary amount of work if you don't need to address modules
individually
    -could potentially be easier to just assume that the import path is the
unique name and reference the module that way (though this has other
problems)
    -egh, need to think about that one.

---------

in any case, this _is_ quite useful justin: this real world example is
perfect. it _is_ easier to just create a module comm manager or something
that gets loaded up only if a module needs to communicate, and have another
module grab the variable from that module communications manager.

I'll think about that one and get back to you.

[binarycloud-dev] A Price Paid for constructors????

[Justin F. <je...@ey...>]

Alex/Guys:

Look, I don't mind exposing my ignorance, but I am floundering
around trying to get "experience" in bolting modules together
and to establish some standards for our company's coding.

What I am sort of wrestling with, now, is the tradeoff between:

1.  Writing code "correctly"
2.  Trying not to clutter up global scope with potential
	danger of name clash
3.  Increase performance, or the corrollary, not inadvertantly
	decrease performance.

I will give you an example, here, which you may not think
typical.

I have bolted together an "application" with a module that allows
you to UPDATE/INSERT/DELETE, find in any field,
sort on any field, jump to any record, browse all records
for all databases in my system.  It works quite well, and is a
general module that I can bolt into other "applications".

Since it is general, it makes one humungous number of SELECT's
in the constructor when you must fetch/SELECT

- All database names
- All tables in each database, meaning, additionally
	* field names
	* field types
	* field lengths
	* field options

which I collect and put into a large data structure.  This module/Class
is called EditTable.

OK, this is a big hit on MySQL, all done in the constructor.
You can even see the page generation is slow, even on a development
machine with your "private" database(s).
You can imagine what it would be if you have 50 databases with
10 tables each, each table having, say 10 fields, and 50 clients
using it.

Now, being a good boy, in other classes, when I need this class,  or
something from it, I instantiatiate it with a new EditTable inside
another module instead of having the EditTable module put the
data structure in global scope one time, and have other modules go check
on
the existence of that data structure, and if not there, do
a new EditTable.  It is interesting to watch MySQL query logging
each time EditTable gets instantiated.

But, I am going to use this data structure in a Report Generator,
where you need the same kind of data to be able to generate reports
dynamically, and in other modules.

So, I have a tension between going global, meaning, putting the
data structure global, so I don't have to instantiate a new
instance of EditTable, and taking the big MySQL hit over and
over, technically unnecessary.

THIS WAS NOT THE CASE when the modules used Init(), as, in theory
Init() was only called once when loaded by BC, no matter how many times
you instantiated
the class inside another module.  Before, you had to specifically
call Init() again (if you needed to, with options/different args).

Thus, the switch to constructors has caused a "penalty" when you have
a whole bunch of database work in the constructor.

What would you guys do?

Is it even worthwhile to consider asking Alex for some kind of
registration
facility for things/(big things) that indeed have a good reason for
being global?
Yes, I do respect Alex's "law" that he wants globals to be held to
a minimum.  What is the sweet compromise here????

I should qualify this and way we _will_ run the xml through xml2php, we

Re: [binarycloud-dev] So-called user constants

[alex b. <en...@tu...>]

because we run those xml files thourgh an xml->php makefile that (you
guessed it) turns xml into php with various filters.

that allows us to use xml because it is convenient and clean, while avoiding
the performance problems associated with parsing xml at runtime.

You're right, that isn't correct.
It  could be that the module doesn't have a correct package declaration.

are other modules working?

Why would you want to use xml configuration file instead of php?
Wouldn't you think php parser works faster (even without with the help
of php cache / zend cache) than xml parser?

Please enlighten me on the reason.

Thanks

OK the #2 try was wrong too, so here's the 3rd try:

for i in $*; do

[binarycloud-dev] CVS

I _just_ retrieved the latest CVS, and was able to install when I
noticed this.
Doesn't look quite right, thought I would ask first:

Re: [binarycloud-dev] So-called user constants

[alex b. <en...@tu...>]

correct.
these are constants that are used by the system, but always set by the user.

all constants are implicitly global.
you can put a declare in conf.php, or you can declare a constant in your
module. it's up to you.

Yes. The .xml won't know anything about the set of constants, just that a
certain xml structure should be ripped into a php define.

so you can add whatever you like.

It would be the latter, define.

They are also user constants. Agreed, the BC_ prefix ones are "special" and
I may make an effort to make that a little more clear - but both 'sets' of
constants come from the dev.

user/conf/conf.php (for the moment, soon the conf.xml)

That would be stupid. So, yes, you are correct.

This I don't understand - all 'constants' loaded by the system are
system-wide (not page specific) and implicitly global.

You will _only_ have defines available there.
