Hi Everyone,
Please pardon me if I am asking extremely stupid questions, but I'm
starting to do some work with my database and I have a few questions
about EnterpriseObjects and database things in general...
The first question is about creating unique data... I have a user
object and I need unique usernames for obvious reasons. Now, I know
it is unlikely, but let's say that two visitors attempt to create a
user at the same time and they happen to pick the same username.
EOQualifier qualifier = User.SCREEN_NAME.eq(username);
if(User.fetchUser(ec, qualifier) == null) {
User.createUser(ec, email, password, username);
ec.saveChanges();
}
If these fired at the same time, is it possible that two users with
the same username could be created? If so, does anyone have any
pointers to prevent duplicate data?
The second question regards security/sql injection. Is there any
sort of user input I should be on the lookout for in my
validateUsername method? Like username "admin'--" or some such? I
assume that as long as I stick to EOQualifiers and don't touch the
SQL myself that all the input will be properly escaped...
Finally, third question... I'm using MySQL. I will ensure InnoDB is
used by default as mentioned here:

Use InnoDB to esnure transactional commit/rollback.
In MySQL 5.0+, add this param to the config file:
innodb_rollback_on_timeout
IMHO, MySQL is a good database server. Have a look at the silent
changes it makes . AFAIK all these conditions should be handled by
your validation methods before they ever hit the database anyway, so
should not be a problem. YMMV.
http://dev.mysql.com/doc/refman/5.0/en/data-type-defaults.html
With regards "silent" truncation of varchars where they exceed the
length of the field, this can be configured to throw an error .
again by configuration. I would think your EO validation methods would
check for column length anyway IIRC, EOF will error by default if
it exceeds the field length specified in the EOModel.
http://dev.mysql.com/doc/refman/5.0/en/char.html
http://dev.mysql.com/doc/refman/5.0/en/server-sql-mode.html
In general MySQL "out of the box" configuration is absolutely useless.
To use MySQL, you *MUST* configure your installation this is done
generally with the /etc/my.cnf file which specifies launch arguments
for mysqld. Read the fine manual or Jeremy Zawodonwy's book "Advanced
MySQL".
IMHO, MySQL is very versatile and offers a number of different
"engines" for different applications and offers many configuration
options to tailor the functionality as you wish. This is just my
opinion, so feel free to use whatever database you like. In any case,
pick one of the ones that is popular with WO developers so that you
can get help when you need it. Use prototypes from the start and it
will be easy to change database platforms later if you wish.
Thanks everybody! I really appreciate the help everyone here
provides.

You need to create a uniqueness constraint on this field in your
database. The database is the only place that can guarantee this
uniqueness requirement is honoured.

As long as you don't send anything through EOF as raw SQL you should
be safe from SQL injection attacks.

at least I think anyway as I now have new problems. Turns out the
iPhone SDK does install 5.4.2, which overwrote all the frameworks

What problem did that cause?
Initially, we were getting weird adaptor errors; I believe I'd
posted them previously. Basically: I run both 5.4 and 5.3 locally,
so don't see issues in dev when crossing the 5.3/5.4 line. However,
it would seem logical that if I developed locally (and
unknowingly;-) on 5.4, and then pushed the built app up to a Tiger
server running 5.3 only (and apache 1.3x etc) that there _could be
problems. After uncovering "extreme stupid mistake #1" I assumed
that contributed towards the adaptor errors I saw subsequently.
OK, thank makes sense.
No problem I say, simply run the convenient wo53 script and I'll
be back in biz. Project rebuilt, manually configured the
MacOSClasspath.txt and MacOSXSClasspath.txt to get rid of the $
{jvm} bad argument
I had hoped that it was the iPhone SDK changes that caused this.
It sounds like it still happens after you re-installed 5.3? Sigh.
Yes, but eventually I began to think it was probably just the
project getting flaky so decided to rebuild a new one. This time,
did NOT select Wonder Project from the wizard; just made it a PO WO
project and added the wonder dependencies manually afterwards. That
fixed everything right away. But I first started by removing the
wo.system embeds, then the wo.local embeds, just to make sure there
wasn't something else going on. Now, it's not really related, but I
noticed on the wonderful (seriously) output you get on start up
(using Wonder) we now have this jar checker that very helpfully
determines what jars may have duplicate references. I have loads of
them; even on this new project. I'm not linking to the checked out,
imported workspace projects (I would, but I have some issue with the
checked out version of Wonder that seems to prevent me from ever
being able to build it all and install from subsequent cvs updates),
I have had a few problems, but I think I have them worked out. What
is happening for you?
so I occasionally download the latest Wonder built frames... and use
the check outs largely as reference within the workspace. Instead, I
reference the installed frameworks. So, even with no project
dependencies and with the local libraries linked in properly I'm
still seeing the jar checker warnings. But perhaps this is also
something that the new classpath stuff will impact.
Specifically what warnings do you see?
and fix the ERExtensions not showing up before ...foundation in
those files, (and it would be great to at least figure out how to
make eclipse do the right thing here; configuring the build path
didn't spotlight any obvious answers).
Mike has some very highly anticipated changes to WOLips classpath
handling that he is sitting on. I expect it will be a while before
he is ready to commit them.
Yes, and absolutely understandable for sure. My question was more
out of trying to understand all those internal details so I'd be
able to save my own day;-)
I have not quite figured out how that can work right now either. I am
hoping that Mike commits before it gets too far up my priority list.
Anyway, as a refresher, I've got a built .woa which is completely
embedded; all System and Local frameworks are included in the
built .woa. Now, when trying to start up I get this:

lie there. Check the files in woproject/ (or the build.xml or ...

I'm dealing with a WebObjects app that has suddenly started experiencing OutOfMemoryErrors. Probably due to a gradual increase of data in the database and large to-many relationships. You might want to check the wiki for some advice on managing large relationships if that is the problem. Or just an increase in data and no fetch limits.

I will copy wo-dev. http://wiki.objectstyle.org/confluence/display/WO/EOF-Using+EOF-Memory+Management#EOF-UsingEOF-MemoryManagement-NSUndoManager The advice given regarding EOEditingContexts and their NSUndoManager is well-meaning but wrong. 1) === I have found that doing: editingContext.setUndoManager(null); Will create the following error when you attempt to delete and save an EO that has a delete rule of "deny" on an existing relationship (using WO 5.3): java.lang.RuntimeException: java.lang.IllegalStateException: Editing context needs an undo manager to recover from delete propagation problems. Do not set the undo manager of this editing context to null. Yes, you need the undo manager if you have delete rules, esp deny rules. 2) === Additionally, if I try the following: editingContext.undoManager().disableUndoRegistration(); I find that little undo / redo pieces are still allocated in memory... which defeats the purpose of removing registration. This can be verified with a tool such as Jprofiler, etc. Any tool which allows you to view the java heap and memory allocations. Yes. 3) === After reflecting on notes #1 and #2 above, its safe to say that the NSUndoManager is an integral part of the EOEditingContext and should neither be crippled nor removed. Calling the following after saving changes, as currently recommended in the wiki, might make sense: editingContext.undoManager().removeAllActions(); That is what I do. I have an EC subclass that calls this after a successful super.saveChanges(). That way, I don't have to remember to do this. but, in the same breath, we should also recommend that "dispose()" might want to be called and explicitly setting the editingContext to "null" if the editingContext is no longer needed. But, if that's the case, there is no point even worrying about the undoManager in the first place. That depends on how the EC is used and how long it is kept around.

D2WList Default Sort Issue.
Hello -
I have been using D2WList for my reporting needs and never realized
that it had a default sort based upon the first attribute in the
eomodel ?!
My binding for D2WList is :
List: D2WList {
entityName = session.reportEntity;
list = session.theList;
displayKeys = session.theReportKeys;
}
I am using a just a list or plain old NSArray. No WODisplayGroup etc.
The question than becomes where do I get access to the D2WList to
change the default sort behavior? Is there a rule I am not seeing for
it?
Thanks
James Cicenia
