Thanks a lot Wim.
About dbo, I need an example about migration scripts. Suppose that I
have an application running using the class below
class User {
public:
std::string name;
template<class Action>
void persist(Action& a)
{
dbo::field(a, name, "name");
}
};
Then in new version, I've added a new attribute called age
class User {
public:
std::string name;
int age;
template<class Action>
void persist(Action& a)
{
dbo::field(a, name, "name");
dbo::field(a, age, "age");
}
};
There is a method called createTables(). Is there (or will be) a
method to update existing tables (Ex. updateTables)?
If not, I need an example code how to add age to an existing database
(need SQL queries I guess)
About tests, I mean a black box user testing, a browser automation. Any ideas?

depends on your application. Simple requests are handled within a
milisecond, but it really depends on what the handling of those events
takes. Same goes for memory consumption<br>
<br></div>2. There are many strategies. You can avoid the impact of an
application by a good support for URLs, so that a full reload of the
session (which happens when you'd restart a server) would put you back
in the application where you were. This would be mostly similar to
what you get with other frameworks. You can also use a reverse proxy
that forwards sessions depending on some prefix in the session ID, and
deploy the new applciation with a different session prefix, and
configure your reverse proxy that new sessions go to one instance
while the old sessions are still served by the old instance (e.g. by
running them on separate ports). When there are no sessions left in
the old instance, you can kill it.<br>
<br></div>3. afaik Wt::Dbo has no features for automatic database
migration. You will have to run your migration scripts
manually.<br><br></div>4. There's Wt's WTestEnvironment, or what kind
of tests are you looking for?<br>

couple of questions.<br><br></div>1. Is Wt convenient for internet
Saas applications? On what load (Ex. how many active users, concurrent

<br></div>2. When a new version of my application comes, how can it be
deployed without interrupting the active users (replace myapp.wt with
its new version). I am planning to use built in http(s) server. Is it
possible to update on background?<br>
<br></div>3. If I add a new attribute to a class whose objects are
stored in database using Wt::Dbo, Is it possible to apply a patch to
database. I mean, is there a class like a database-patcher which
checks my new models and apply differences to database.<br>
<br></div><div>4. Does anyone use an automatic testing suite
effectively. Any recommendations?<br><br></div>Thanks a
