Re: [Cppcms-users] How to compile cppcms with c++11

[Shiv S. D. <shi...@gm...>]

Change line no. 114 from

set(CXX_FLAGS "-Wall -Wextra")

to

set(CXX_FLAGS "-Wall -Wextra -std=c++11")

it should work with both clang and g++.

[Cppcms-users] How to compile cppcms with c++11

[陈抒 <csf...@gm...>]

Now, it's time to develop c++ 11 app, but do not know how to compile cppcms
with c++ 11 option using clang or g++?

Re: [Cppcms-users] Distributed data

[Shiv S. D. <shi...@gm...>]

Agreed on that. Also varnish requires learning of Python little bit and one
more software. For dynamic content for example a user profile should always
be cached with CppCMS. But something like a login page can be cached with
Varnish as that is static.

Re: [Cppcms-users] Distributed data

[Artyom B. <art...@ya...>]

The problem with most of caching systems that are not connected to the framework itself is "invalidation" problem.

The cache system does not know when and what to drop.

Internal CppCMS cache system works both very fast and smart enough to keep the data as consistent as if it wasn't cached at all
(of course with some effort on your side)

  What?! There is a huge difference between
 
  reading/writing/serving local
 
 
 
  files and using a database. Also DBMSs are only useful if
 
  you have
 
 
 
  structured data and a lot of it. Files are better for a

  data (like 10-20 users with a password

  And please, do not use SQLite in your productive
 
  environment. For >10k
 
 
 
  entries the performance is really bad! Use something
 better,
 
  like PgSQL.
 
 
 
  Also do not start with a certain DBMS and then change
 later
 
  to an other,
 
 
 
  because you use hacks and non SQL-Standard statements.
 Even
 
  if you use
 
 
 
  strict SQL(-99), there is not guaranty that you can use
 your
 
  statements
 
 
 
  on an other machine.
 
 
 
  Always use the same DBMS in enviroment and productiv.
 
  Setting up a PgSQL
 
 
 
  Server is not as hard, as you might think (at least under
 
  *nix).

We can put Varnish in front of CppCMS/webserver for caching. Varnish speeds
up thing a lot.

Re: [Cppcms-users] Distributed data

[Artyom B. <art...@ya...>]

Ok guys...

For sharing distributed data... Yes database is needed whatever, SQL, NoSQL or anything else.

Now to scale up you need to think about many things and database architecture. There are many
methods for scaling stuff up like partitioning, caching etc.

Now the second thing is caching.

If for every small chunk of data you'll go to SQL you'll kill your application faster. You need to use
caching. CppCMS provide distributed cache systems with triggers support that helps a lot
to reduce the load.

Ideally, you should keep almost everything in memory. What you can, like big tables, keep in optimized
database. Consistency can be easily handled with cache system.

And final note: it is always better to cache output (i.e. generated HTML) as you save
both HTML "rendering" time and gzip compression.

 What?! There is a huge difference between
 reading/writing/serving local
 
 files and using a database. Also DBMSs are only useful if
 you have
 
 structured data and a lot of it. Files are better for a
 small amount of

 Here are the compressed

Re: [Cppcms-users] Distributed data

[Shiv S. D. <shi...@gm...>]

As I said data has to be distributed and SQL databases have to be sharded
which is a pain. That is because I then need to do things which I should
not be doing really. I will be doing databases' job.

Re: [Cppcms-users] Distributed data

[Eric G. <con...@gm...>]

Maybe you should modulate your words/opinion a little bit around the
context of the question at first, seems to be a small app and also the fact
that a person able to use an api like cppcms sure have the ability to
understand sql eazily.

Telling me I'm wrong about sql is a database make me suspect you are just
in a mood to throll in playing with words...  of course I write sql is
database for short... and that was enough for the purpose of this answer to
the author in this context.  The long answer is sql is query langage to
access datas stored in database.

Any good faith person understood that I made a really short answer to go
fast only to have a general idea to interest someone to go further by
himself.

Sqlite is faster to dev yes for local files like with qt framework for
example where a direct class can connect to data without even any
coding...  with a model table widget for example.  But this is not a
subject of this mailinglist.

I won't take more time to justify my answers with you anymore.

What?! There is a huge difference between reading/writing/serving local

Re: [Cppcms-users] Distributed data

[Eric G. <con...@gm...>]

SQL is a database...

It's almost easy to start using sql...  for simple queries.

Easy to share datas between multiple computers on a network.

Setup connexion
Open database...
Select or update query...
Close database

even if you use read/write local files, I recommand using something like
sqlite, doing sql queries on local database without server.   For me, I
found faster to dev with sql even on local database files than on manual
read/write files...

Even if data can also be stored in cookie, a specifiq key/value pair may
not exist...

Re: [Cppcms-users] Distributed data

[Shiv S. D. <shi...@gm...>]

I thought over it and I think it is better to share using a database layer
to serve as an abstraction layer for storage mechanism. SQL servers do not
cut job for a person like me who is alone. I have no resource to shard and
maintain them.

Even though cookies are stored in browser they are sent by servers or
servers have to send cookies to browser to be stored and hence you can
always set that. CppCMS recommends session data in cookies or you can store
it server side also.

Re: [Cppcms-users] Session data from client does not reach cppcms::rpc::json_rpc_server method?

[Eric G. <con...@gm...>]

Maybe I'm wrong...
But...
What I understand about sessions, is that... the cookie is the serial
number of the session... not the content of "my_key".  Your key belongs to
the session..

So..

the session can exist (get_cookie return something) but the key inside the
session may not exist at the same time of course (is_set(my_key) return
false).

Re: [Cppcms-users] Distributed data

[Eric G. <con...@gm...>]

I'm not sure to understand...

Maybe you need a file sharing somewhere or even a server?  Samba... NFS...
A simple windows share...
Maybe you need a client/server system or SQL server?  postgresql, mariaDB...
Maybe you need P2P if so, take a look a ZeroMQ (0mq) it's a very good
library.

Re: [Cppcms-users] Session data from client does not reach cppcms::rpc::json_rpc_server method?

[Shiv S. D. <shi...@gm...>]

But to set a client-side cookie you set it from server side. That is server
stores session data in client in the form of cookie. Another thing which
can happen is you use client side cookies using something like jQuery
Cookie but that is a different question.

I see in the sessions example that when form data is received it sets name,
sex, state and age. I have not yet studied how things work in asynchronous
applications.

My knowledge is limited in this regard so I would rather wait for some
expert to comment.

Re: [Cppcms-users] Session data from client does not reach cppcms::rpc::json_rpc_server method?

[CN <cn...@fa...>]

Aha!



I already had
read [1]http://cppcms.com/wikipp/en/page/cppcms_1x_sessions before I
posted my question. After re-reading it, I finally notice that



cppcms::session_interface::load()



must be called every time after the request arrives in asynchronous
applications.



session().set("my_key") is automatically called by the framework if
client side cookie named "my_key" is set. This means we do not need to
manually call session().set("my_key") if that cookie is already set.
Please correct me if I misunderstand it!



Regards,

CN

If you want to retrieve session().is_set("my_key") which appears to be
your key
then before retrieving you need to set it as shown in
[2]http://cppcms.com/wikipp/en/page/cppcms_1x_sessions
For example,

session().set("my_key", true);

before it will return true.

Taking void post(std::string const &author,std::string const &message)
in file json_rpc_chat.cpp as an example,

session().is_set("my_key");

appears to always return false. However,

session().get_session_cookie();

does return a string. Am I misunderstanding http or the framework?

Thank you!

Re: [Cppcms-users] Session data from client does not reach cppcms::rpc::json_rpc_server method?

[Shiv S. D. <shi...@gm...>]

If you want to retrieve session().is_set("my_key") which appears to be your
key
then before retrieving you need to set it as shown in
http://cppcms.com/wikipp/en/page/cppcms_1x_sessions

For example,

session().set("my_key", true);

before it will return true.

Re: [Cppcms-users] cppcms hangs if cppcms::application ctor throws exception

[Karsten A. <kar...@go...>]

Aha, in debug mode the program behaves as expected. In release mode it
hangs. Any ideas?

[Cppcms-users] Session data from client does not reach cppcms::rpc::json_rpc_server method?

[CN <cn...@fa...>]

Taking void post(std::string const &author,std::string const &message)
in file json_rpc_chat.cpp as an example,



session().is_set("my_key");



appears to always return false. However,



session().get_session_cookie();



does return a string. Am I misunderstanding http or the framework?



Thank you!
