Re: [Pharo-users] OmniBase for Pharo 6

2018-07-25 Thread Matias Maretto

Marco: thank you for this. A few weeks ago when I was trying to find the "lock" 
problem I saw this method but I did not dare to change it; and just as you said 
I  been using OminBase with no problem, but never runned the Garbage Collector, 
Surely I was going to have a bigger problem in the future for not running the 
garbageCollect.

I have just update this method on my project and tried both the garbageCollect 
and the reorganize method , both worked fine (win 7 32bits, later I am going to 
test on Win 10 64 bits).

Thanks again.

Matías.

One serious problem left: OmniBaseTest>>testGC fails.

Have a look at the 2 methods

/ODBContainer>>lockDataFile
"Dec, 2010 sas: this code was relying in evaluating a block that was
happening only in win32
but not in *nix. So now I'm making it wait for the lock and then execute
the code normally
because it seems the intention was the same."
| currentSpace defaultSpace |

activeDataFile waitForAddingLock.
currentSpace := activeDataFile == dataFileA ifTrue: [0] ifFalse: [1].
defaultSpace := objectManager defaultObjectSpace.
currentSpace == defaultSpace
ifFalse:
[defaultSpace == 0
ifTrue:
[dataFileA isNil ifTrue: [dataFileA := ODBObjectStorage
openOn: self dataFileNameA].
activeDataFile := dataFileA]
ifFalse:
[dataFileB isNil ifTrue: [dataFileB := ODBObjectStorage
openOn: self dataFileNameB].
activeDataFile := dataFileB].
^self lockDataFile]


ODBFile>>waitForLockAt: pos length: length whileWaitingDo: aBlock
"Wait for lock at given position.
Evaluate aBlock in each iteration."

"Dec, 2010. sas: evaluating code in each iteration while waiting sounds
weird but whatever.
I think this was designed on the wrong assumption that the OS always
will provide a false
in the first try but what actually happens is that in win32 you always
will
get at least one false but in *nixes you don't do see that happening
(which is totally reasonable).
BEWARE of stupid code relying on this stupid assumption (I've already
patched #lockDataFile because of this)."

| startTime currentTime |
(stream lockAt: pos length: length) ifFalse: [
startTime := Time totalSeconds.
[stream lockAt: pos length: length] whileFalse: [
aBlock value.
currentTime := Time totalSeconds.
currentTime - startTime < self timeOutLength
ifFalse: [
ODBLockNotification signal
ifTrue: [startTime := currentTime]
ifFalse: [^ODBCannotLock signal
/

So "sas" did a refactoring in 2010 because he/she thought it is stupid code.
This code change breaks the GarbageCollection of Omnibase.

I reverted the first method to the original code of the Omnibase author,
David Gorisek:

/lockDataFile

| currentSpace defaultSpace |

activeDataFile waitForAddingLockWhileWaitingDo:
[currentSpace := activeDataFile == dataFileA ifTrue: [0] ifFalse: [1].
defaultSpace := objectManager defaultObjectSpace.
currentSpace == defaultSpace
ifFalse:
[defaultSpace == 0
ifTrue:
[dataFileA isNil ifTrue: [dataFileA := ODBObjectStorage
openOn: self dataFileNameA].
activeDataFile := dataFileA]
ifFalse:
[dataFileB isNil ifTrue: [dataFileB := ODBObjectStorage
openOn: self dataFileNameB].
activeDataFile := dataFileB].
^self lockDataFile]]
/
I removed the comment of "sas" from the second method. It is wrong.


The garbage collection works again and the test is green. GC is an important
feature of Omnibase.
It creates a new repository/database file and copies the data into the new
file, compressing the data.
It keeps your database compact and clean. If you don't run it (frequently)
your db files keep on growing...

Matias, your fixes are absolutely valid and should be published - together
with the one above -  in Esteban's repository.

Thank you for the info Peter ; I have been working storing and retrieving data 
, everything works fine. I have an ODBPErsistDictionary with almost 20.000 
objects on it, I really get sorprised of how fast can resolve "select:[] 
commands"; I know it is not related with the subjet we are working, but well 

Hi Matias (and EstebanLM)



I have explained the problem with storing and retrieving Date. Looking through 
the OmniBase code in the repository, I see that there is a whole series of 
extensions for many of the standard classes, which provide methods for 
serializing and deserializing instances of those classes. The extension for 
Date class ignores the start time, and simply saves the day number; the 
retrieval method can only use the days, and so cannot take account of the 
offset for the time zone. If it is necessary to save and restore dates in a way 
which is time-zone sensitive, it will be necessary to modify the code for 
serializing dates to store day and offset. I have not yet worked out how the 
methods are structured, so I have not tried to recode, but all the methods I 
have looked at are only one or two lines, so it should not be difficult.



Looking through the classes with extensions, I realise that we may need to 
check rather more examples to be sure that everything is handled correctly. I 
did one little test with String. The standard test in TestEquality just stores 
and retrieves ‘Hello World’. To check that it could handle other encodings, I 
tried the test with a German string encoded in utf8. This worked OK. So thus 
far everything is fine, but it would be a good idea to check correct retrieval 
each time we persist a new class of object.



Best wishes

Hi Matias



A further report. I have worked through the test suite in OmniBaseTests, 
running each test individually. I now have all green except two – testEquality, 
which fails on the storage and retrieval of ‘Date today’, and testGC, which 
fails for reasons I have not yet found.



The worrying thing is the apparent change in the instance variables of Date – 
see my exchange with Alistair Grant in another thread. I shall try to work 
through the way OmniBase saves and resets the instvars, just in case it might 
be a general problem.



I shall let you know of anything else I find.

Thanks. I have made this change, but it does not affect the tests I have run.



I have focused on getting the test suite in OmniBaseTests to run. So far I 
still have 5 greens, 7 reds and one orange. The greens are all the first five 
test methods in the browser list; it seems it half fails on the sixth one 
(TestEquality), hence the orange, and then red for all the rest.



One problem is that the test database is created at the start of the test 
suite, and then not removed at the end. This seems to mess up the next attempt 
to run the tests. I tried to run the OmniBaseTests>>#tearDown manually, but it 
fails, so I have to exit Pharo and delete the test database in Windows.



I intend to continue running the test suite, but I shall run the tests

2018-06-22 Thread Matias Maretto

Peter: when I run code like this example:

db := OmniBase createOn: 'C:\temp\testOmni'.
aTrans := db newTransaction.

aTrans root at: 'Hello' put: (OrderedCollection with: 1 with: 2 with: 3).
aTrans commit.
db close.

db := OmniBase openOn: 'C:\temp\testOmni'.
aTrans := db newTransaction.
(aTrans root at: 'Hello') size

Everything is fine, but sometimes when I close an reopen the base I get the 
"lock" error, but even when I get the error the base is still opened and 
transactions run fine. I will take a closer look to the lockFIle method.

I will tell you if I find a solution. (I am using Win 7).

Re: [Pharo-users] OmniBase for Pharo 6

2018-06-22 Thread Matias Maretto

Esteban: it's working fine, I had to made a minor corrections on 2 FFI calls 
and now everithing seems to be working fine.

For What I saw with Voyage-UnqLite only String Objects can be used to 
searilize; Omnibase allow to persist almost any kind of objects, thats the part 
I like about it.

I did it manually and I took like 5 min :P
but this was really easy, just a bunch of FFI calls.

Hi,

I just made a “blind port” of OmniBase to Pharo6+ (migrated the old FFI to new
UFFI).
New port is here:

https://github.com/estebanlm/OmniBase
[https://avatars0.githubusercontent.com/u/513630?s=400=4]<https://github.com/estebanlm/OmniBase>

estebanlm/OmniBase<https://github.com/estebanlm/OmniBase>
github.com
OmniBase is Smalltalk efficient objects repository, BTree and filesystem based
with full ACID features

and can be load like this:

Metacello new
repository: 'github://estebanlm/OmniBase/src';
baseline: 'OmniBase';
load.

PLEASE note I’ve never used OmniBase and I don’t know if this port will work
out of the box. But if it was working, it should continue working now (and this
list can help to get you rolling).

cheers,
Esteban

ps: I always wanted to do a Voyage-OmniBase… maybe this is the moment? :P

I too used it in Dolphin and it was fine, But i don’t think it gets used much
in Pharo and so has probably decayed, isn’t Voyage an object dB or Gemstone?

(Todd & everyone, a gentle reminder to try and leave personality opinions at
the door , we’ve already had another thread that got overly heated
unnecessarily. Our community is small and we need to avoid knife fights. The
technical stuff is already hard enough)

[Pharo-users] Morph & MVC tutorials

2018-06-06 Thread Matias Maretto

Hi guys, I have been doing some things with Dolphin, actually feel very 
confortable with it, but now I am trying to learn Pharo. I have noticed that 
many things are quite similars,  but others are very differents, one of this 
things is the Visual Part, can someone point me out some good tutorial for 
Morph and MVC, I trying to understand the use of these two "worlds" and I want 
to "play" a little with them.


Thanks.


Matías.
