Okay this answers my question.

So now I can tell you Richard, ONLY because of columnar format,
Valentina DB can do some operations 20 times faster of any ROW-based DB.

And if multiply this to other features of Valentina you can become
With Valentina 20 *4 * 2 = 100-200 times faster.

Very not true :)

When you talk about speed and time, all is relative.
You need talk about ABSOLUTE numbers instead.
   
For one person/project/app 10 sec for search is very fast,
For another this is incredibly slow.

Richard, when you say, I NEED SPEED, you must say:
  I want query in 100 sec or in 0.01 sec

Only having this info, people can advice you.

Exactly Richard. 

This is named "degradation of DB" on grow of

A) records number in table(s)
B) records number in the RESULT

Yet from 1996 year, when I did my first benches of Valentina against
 FileMaker, 4D, Access, mySQL, ...

And this very first thing I have found also.

Most dbs if not all, have powerful degradation when recs number grow.

Also exists some special N related to RAM of computer. Below this N dbs go
yet more or less nice. After N degradation can go by jump x10 worse.

With Valentina this N was much higher in the same RAM, because of much more
compact db format for data. And after N it was very good yet.


For example, if for most dbs difference in time between 50 and 500,000 recs
in result is huge, for Valentina it is almost flat.

Valentina DB is faster 100 times of SqlLite, mySQL

And can be perfectly embedded into commercial application because it is
royalty free.

You need Valentina DB.

Okay you need 5K for each record.
How many fields?

Let me remind that Valentina has columnar format.
This is huge advantage.

Also Valentina can give you not only SQL way but NON-SQL way,
Which can be additionally 10-20 times faster!

--
I can tell you store, that Valentina was tested for AOL Europe by their dev
team. Against Berkly,  mySQL, postgre, and other dbs. SqlLite even was not
in game of course.

Task was so simple. Table has 2 fields {URL, PictureBannerAd }

So when somebody ask for a WEB page, it needs find banner to be shown.

As they told, e.g. Berkly have give 100 faults per time (min our hour I not
remember now).  Other dbs also. Fault means that banner was not found  by DB
in time less of timeout.

Valentina have give them zero faults.


Let me underline this very important feature NON-SQL-ness of Valentina.
As well as very powerful SQL.

Today is very modern stream talk about how SQL DBs are bad, and how cool are
NON-SQL with Key-Value.  Guys, be happy, Valentina is perfect for both
tasks. :-)

If talk about details, in V4REV API (and most others Valentina ADKs) you can
use not SQL way to do searches and sortngs using
   VField_FindValue()
   VField_FindRange()
   VField_FindLike()

And other similar search methods.  They are really FASTEST POSIBLE way.

Re: [OT] G3 and USB 2

[-=>JB<=-]

Another important thing to remember is some drives like the LeCie drives
can be very touchy.  Do not use them to run programs or do much work is
the best way to prevent crashes so just use it for a back up drive.  And to
unmount the drive you might be safest shutting down the computer then
turning off the drive and rebooting your computer again instead of using
the normal unmount option.  I figured it out the hard way but your drive
may not give you the same problems I had.  And when I say I learned
the hard way I had to recover the drive which was more learning and
it does not always work recovering files.

Re: Stress-testing SQLite

32TB db limit according to this:

Maybe use limit and offset to page through query results though.

Just a reminder, which you probably don't need at all, but I had this 
same experience with PostGreSQL recently, but probably for different 
reasons:


but FWIW...

I was using and old example SQL stack... small data returns were fast, 
but a lot of data (select * from table whatever.. i.e. "everything")  
from a PostGreSQL database  adding it to a display field. It took 
forever...


Then I remembered "Dont' Do That!"

When I got all the data in a variable and just posted to the field once, 
it was "like 20 times faster."

Hi Richard,

Probably just a single table, with about 20 columns.


That can make a big difference to the performance if there are JOINS
involved.


None - all flat.  I'd even considered rolling my own data storage for 
this one, but the indexing is more work that I'd care to do if I can use 
an off-the-shelf solution.



If not, then that's not so much a problem.


Good to hear.


Will the user always apply a WHERE filter to the data?


For the most part, yes.  I'll have about three or maybe four indexes, 
and most of the time the searches will be using those.  I may have the 
odd case of a substring search, but the performance hit is anticipated.



What's the potential return record set count on a typical filter?


It'll vary, and in my own tests that seems to be the only bottleneck

Thanks.  Don't knock yourself out; I'll be continuing with my own tests

Stress-testing SQLite

[Richard Gaskin]

I have a need coming up for a data store that can robustly handle at 
least a million records, ideally up to five million, where each record 
may be as large as 5k.


I don't need relationality, so for me SQLite is an option but only an 
option; I'm happy to consider other options as well. (Yes, it has to be 
SQLite rather than MySQL, because it needs to work embedded with a 
commercial application).


Have any of you done stress testing on SQLite to that degree?

I've tried finding even anecdotal data on the web for SQLite limits, and 
while I can find citations of theoretical limits I haven't come across 
real-world usage stories of data sets that large.


Should I be confident in SQLite as a storage solution for that?  Should 
I be scared?


Thanks in advance for sharing your experiences with large data sets if 
SQLite.

[OT] G3 and USB 2

[Richmond]

So; having got a generic USB 2.0 PCI card recognised in my
Back-to-the-Future G3 Mac I have started having a lot of 'fun' with it:

1. It works very well with my faithful Belkin Nostromo.

2. When I plug 2 external USB 2 hard-drives into it they are
 not recognised AND nor is the Nostromo.

Queer or what?

Re: The siglum key explained.

[Peter Brigham MD]

See Wikipedia:

http://en.wikipedia.org/wiki/Keyboard_layout#QWERTY

The siglum at topleft seems to be found in Scandinavian countries and  
in Holland, at least in the QWERTY layout. The british version at  
least in this article, doesn't have any siglum key at all (must be an  
alt/option-key combination).


I never realized how much variation there is in these things.

Suggestions?  Remember, they have to work within the Metacard IDE,
and I can't know ahead of time when the user has finished drawing or
adjusting the line.  Obviously, the Metacard IDE itself has solved
the problem (e.g., all of the IDE stacks remain in use not edit
modes), but I remain baffled.


The IDE doesn't matter, it works the same way in any IDE and is normal 
engine behavior. Both LiveCode and MetaCard manage this by making their 
IDE stacks into palettes or modeless windows. Those window styles always 
operate in browse mode.


It's been years since I played with this, but if nothing has changed, 
the engine still sends all mouse messages normally even in edit mode. 
However, both IDEs trap those messages in a frontscript in order to 
manage editing actions. You can get around that by temporarily removing 
the frontscript, waiting for a mouseEnter into a button, and then 
restoring the frontscript and going back into browse mode. But that can 
be tricky and prone to error, which is why it is much easier to just 
provide palettes for user interactions during editing operations. I 
haven't tried it lately so it may not work anyway.

Re: html entities

[DunbarX]

I should have been more clear. Use the ampersand and semicolon to locate 
the original char in the source text. Convert that char with the charToNum 
function.

If your source text actually contains ampersands and semicolons, it is a 
bit more involved. The ampersand itself comes over as "&". So you can find 
this string and deal with it.

But the semicolon appears all by itself. Still, you can determine whether 
it is a standalone semicolon or a terminating tag by examining the chars 
precediing it. I would test extensively.

Another, maybe better, way would be to initially replace those two chars 
with something you never use (I like ASCII 240). Then run your gadget and 
restore them by replacing the resulting strings with "&" and ":".

One could roll a special getprop handler that lives in the script of the

change the text (using replace or merge) to anything you want:

*instead of *
get the htmltext of fld xxx

*call your getprop property instead*
get the htmlConvertedEntitiesText of fld xxx

Re: html entities

I use HTML text not at all, but after looking at the dictionary, it seems 
there is no direct way to do this. I could be wrong.

But it would be simple to take the output and do a little massaging. An 
ampersand seems always to be inserted as a tag when the function encounters a 
character with ASCII above 128, and a semicolon seems always to act as a 
terminating tag.

You can write a widget to find those characters, and convert them to ASCII 
with the charToNum function.

html entities

[Chris Sheffield]

Got a small problem and wondering if there's any way around it.

When getting the htmlText of a field, is there any way to make Rev/LiveCode 
return the numeric html entities of special characters? So for example, if I 
have a word in Spanish, like "día" (accented i), if I put that into a text 
field and get the htmlText property of that field, is there any way to return 
the string "día" instead of "día"? When setting the htmlText 
property, either one works, but Rev always returns the latter.

Thoughts?

Thanks,
Chris

I looked at "siglum", wondering if it has something to do with gollum or glum. 
Well, "Siglum" seems to be a generic denomination for special characters 
(*,#,§,&,@...).
On Mac's character wiever § is called "Section sign", what seems to be the 
normal name in english. It is highly used in legal writing to refer to sections 
of laws and so on.  in french § is usually called "paragraphe" but the nicest 
name is the one of the ampersand (&) : "esperluette".

I'm not sure, but perhaps this has something to do with the new asynchronous 
behavior of the hostNameToAddress function. It seems that urlStatus will now 
return empty for a short period between issuing the load command and the point 
after it has obtained the IP address of the host. (previously this stage was 
done synchronously)

Are you checking for tStatus = empty in your switch? Does your switch control 
do anything that stops the load continuing in that situation?

As an alternative, you could try this (probably not reliable as a permanent 
solution, but it might confirm that this is the problem )  :


on mouseup
