Re: [Cppcms-users] cppdb: getting the full query

[augustin <aug...@ov...>]

Ok, thank you Artyom for your reply.
My problem is that I have never worked with prepared statements. 
I guess now is the perfect opportunity for me to learn one more thing :)

I'll check all of this out and code accordingly.


Blessings,

Augustin.

That is exactly what you are not going to get as CppDB uses almost anywhere
prepared statements, that means that query that is passed is actually:

   "SELECT * FROM user  WHERE id = ?"

And parameter was binded separately on the Specific DB API level, like 
PQexecParams
or PQexecPrepared

This gives significant performance boost (100%-200%) as statements are prepared 
only
once and the parameters are transferred independently.

So don't expect to make this helpful.

Also you should remember that the query itself is not globally available so for 
example
if result binding fails there is no way to get the query itself or in many cases
the prepared statement already lost the information about the original query
as it keeps its statement object rather then the query itself.

Generally it is good idea not to generate SQL queries on the fly but rather
create a set of statements you use and pass parameters via prepared statements.

This is exactly the point, it is not. It may become some server side object
and the call actually would look like:

exec prepared cppdb_stmt_3(123);

This library has very different internals in comparison to dbixx.

I hope you'll re-consider and support it.

We almost never pass a ready-made query, but use dynamic queries most of the 
time.

When we do:
	cppdb::result res = sql << "SELECT * FROM user WHERE id = ? << user_id;
it's very useful in many circumstances to know which user_id was actually 
passed.
Internally, cppdb must be creating the full query before passing it to the 
backend.
I need to have the full query with the replacements made:
	"SELECT * FROM user WHERE id = 123"

Moreover, in a real application, some queries can become increasingly complex 
and increasingly dynamic (e.g. see Drupal and some of its API like 
db_rewrite_query()...!) 
Often, in order to understand why we don't get the result we expect, we need 
to have the very exact query as run by the SQL server.

One more thing: when an application crashes, or throws an error, generally we 
don't know which query in the code causes the problem. Looking at the error 
logs at some generic error message is not useful.
Having the full query appended in the error logs would help to find the cause 
much more quickly.

I don't understand the cppdb internals and don't understand your first point 
("the query just does not exists or is invalid").
But surely, at some point you must be sending a full query to the server, so 
it should be fairly easy to retrieve it.

Thanks. It worked this way.
I should have tried that, because it's not the first time re-building from 
scratch solved a compile problem (I had a similar problem with cppcms, solved 
in the same fashion).

Re: [Cppcms-users] cppdb: getting the full query

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

Currently this is not supported as:

1. In many cases the query just does not exists or invalid.

2. CppDB does not rewrite the query in most of cases as it uses
   prepared statements, so basically the query you give is the query that
   is passed
   
   That was different in case of dbixx which did rewrite most of queries.

Make sure that you rebuild the project from the scratch. i.e.

- Remove build directory
- Rerun CMake with parameters you need.
- Run make and make install as u

[Cppcms-users] cppdb: getting the full query

[augustin <aug...@ov...>]

Hello,

Like discussed previously for dbixx, cppdb lacks the possibility to get the 
full query (for either logging or debugging purposes).

At least when an error is thrown, we should be able to get the full query that 
caused the error. The driver error is not explicit enough.

cppdb_error should implement:
std::string cppdb::cppdb_error::get_query()
which would return the full SQL.

Probably, a similar function should exist in cppdb::session (to get the full 
query even when no error is thrown.

In many cases, it would make development easier.

Thanks,


Augustin.

I may be wrong, but it looks like a problem with cppdb, because I had 
successfully compiled cppcd with the mysql backend 4 days ago, prior to doing 
svn update to catch the latest bug fixes:

Is it a problem in the cppdb makefile, or a configuration problem on my machine?

[Cppcms-users] error in cppdb

[Baptiste D. <bip...@gm...>]

Hi,

I find two bugs in cppdb 

The first is just a typo in http://cppcms.svn.sourceforge.net/viewvc/cppcms/cppdb/trunk/cppdb/frontend.h?revision=1593&view=markup at line 20, you forget a 'T' in #define CPPDB_FRONEND_H

and the second
I have an error when I give an instance of cppdb:session to a function
to reproduce it 

-------------------------------------------------
foo.cpp

#include <cppdb/frontend.h>

void test(cppdb::session sql) {
   sql << "DROP TABLE IF EXISTS test" << cppdb::exec;
}

int main()
{
   cppdb::session sql("sqlite3:db=db.db");
   test(sql);        
   return 0;
}

-------------------------------------------------

g++ -lcppdb foo.cpp -o foo

boom,  I have the followed error during the linking process 

foo.cpp:(.text+0xef): undefined reference to `cppdb::session::session(cppdb::session const&)'

There is no problem serving images with CppCMS this is rather
simple you don't need anything special for it just give correct
content type and write it into output. And of course you
can cache them in CppCMS using internal CppCMS cache.

But still you need to define what you want and how to serve
the files.

You can even do something like that:

    response().content_type("image/jpeg");
    sql << "SELECT image FROM profiles WHERE user_id = ?" << uid << cppdb::row 
>> resonse.out();

I read from some browsing, they are optimally used in 4 parallel
request because of DNS look up time.
If the images small enough to combine, it will give me more
alternative. I think I need some test.
By the way, how many a [maximum] size of an http response? How to
check it? I use firefox firebug plugin, and no information about it.

I think about small, less static, same size, related images, such as
image profile in social web and try another alternative to pull them
with combining and maybe caching. I can use libgd.

First of all, as far as I understand you can just use some css/javascript 
compressor
and use it instead of ordinary file. And probably specialized compressors would 
do a good job.


> How about  combining small images so we can access it with css  sprite?


Isn't it what HTTP-Keep-Alive and for?

Also HTTP/1.1 allows you to send several requests for different images without
waiting for completion of downloading first one. Isn't it better?

Generally most web servers know to serve
static files a way better than any framework I know for a simple reason - this
is what they are benchmarked against most often. They use best OS API like
sendfile or others to do the job done. I'm not sure how much would it
give you to push such thing in framework, also how exactly can you combine 
serveral
images in single request?

[Cppcms-users] combining all js and css requests in a single file

[Aris S. <ari...@gm...>]

Hi,

My opinion in web development, specifically if we have many "js and
css" resources, although we have high performance http server, many
"js and css" requests will result poor performance (vary in case).

A technique used in YUI javascript framework is with combining all
request in single file. They provide, named Combo API to access YUI
resources, complete with its dependency configurator.
Here the example of combining 4 javascript request:

<script type="text/javascript"
src="http://yui.yahooapis.com/combo?2.8.2r1/build/yahoo/yahoo-min.js&2.8.2r1/build/dom/dom-min.js&2.8.2r1/build/event/event-min.js&2.8.2r1/build/element/element-min.js&2.8.2r1/build/tabview/tabview-min.js"></script>

and for css:

<link rel="stylesheet" type="text/css"
href="http://yui.yahooapis.com/combo?2.8.2r1/build/fonts/fonts-min.css&2.8.2r1/build/tabview/assets/skins/sam/tabview.css">

Combo API is useful to minimize http request.

How about added this feature (combo api) in CppCMS so we don't need
combine it ourself?
How about combining small images so we can access it with css sprite?

No wikipp and the blog are different applications

I need to port my CppCMS 0.0.x based blog
to CppCMS 1.x.x, the problem that the blog is so
old and was written in days when CppCMS hadn't have template
inheritance and even forms support, so it is not so trivial
to do this.

So it is the question of time (that I have not so much)

Sorry, I didn't know about that.

By the way, I see your development blog have more features (comment,
tag) than wikipp; or I can enable wikipp as a blog? or you will
develop another blog for CppCMS 1.x.x?

Re: [Cppcms-users] error building wikipp

Hi,

- WikiPP from trunk requires: CppCMS 0.0.x and DbiXX
- WikiPP from this branch: 

      
https://cppcms.svn.sourceforge.net/svnroot/cppcms/wikipp/branches/for_cppcms_v100


  Uses CppCMS 1.x.x and CppDB.

You are compiling trunk version of wikipp with CppCMS 1.x.x and it does not 
work.

[Cppcms-users] error building wikipp

[Aris S. <ari...@gm...>]

hi,

I try to use wikipp and compile it. There were numerous error around
template syntax. I attach it.

Note: I use libcppcms compiled from trunk, and latest version of dbixx

Re: [Cppcms-users] error checkout, make, and make test cppcms framework

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

Thanks,

Fixed in both Boost.Locale and CppCMS, take latest trunk.

Note: this was indeed bug in test rather then the bug in implementation
itself.
