Hi, Did you check if the library is accessable through /usr/lib? And, did you look into the logs? Maybe they have some helpful informations. Hope that helps you.

Hi, have you tried to install the sqlite3 libs on your system? On Ubuntu you would do that with apt-get install: sudo apt-get install sqlite3 libsqlite3-dev Am 24.04.2015 um 15:11 schrieb Sydunenko Oleg: > Hi all, > > I had problem with example "message_board". > > After startup with command /"./mb -c config.js"/ the error > /"2015-04-24 16:05:50; cppcms, error: Caught exception [cppdb::driver > failed to load driver sqlite3 - no module > found]//(http_context.cpp:139)//"/ is appear in console and browser > had 500 response code... > > Thanks in advance > > -- > Regards, > Oleg Sydunenko > > > ------------------------------------------------------------------------------ > One dashboard for servers and applications across Physical-Virtual-Cloud > Widest out-of-the-box monitoring support with 50+ applications > Performance metrics, stats and reports that give you Actionable Insights > Deep dive visibility with transaction tracing using APM Insight. > http://ad.doubleclick.net/ddm/clk/290420510;117567292;y > > > _______________________________________________ > Cppcms-users mailing list > Cpp...@li... > https://lists.sourceforge.net/lists/listinfo/cppcms-users |

Hi all, I had problem with example "message_board". After startup with command /"./mb -c config.js"/ the error /"2015-04-24 16:05:50; cppcms, error: Caught exception [cppdb::driver failed to load driver sqlite3 - no module found]//(http_context.cpp:139)//"/ is appear in console and browser had 500 response code...

Additionally, each process has its own event loop. In multi-process mode you have several - one per process. In future version of CppCMS it is planned to run several event loops per CppCMS process. About sharing. CppCMS supports process shared cache, session and other stuff. However on the application level you should be aware of it. You run multiple instances of the same process so you should be aware of it, for example using some sort of IPC or shared resources. To be honest.

It is useful for development (so you don't have to restart application for a small HTML fix), not more than that. However using shared objects gives more more flexibility. It does not impose performance penalties, unless you turn the "auto-reload" option on explicitly.

I have some questions about cppcms. I'm interested about building new project with Cppcms but not familiar with it yet and I want to know in detail. 1. Can cppcms run multiple threads asynchronously? I know it can handle asynchronous requests by event loop but can it be run with thread pool and run several requests simultaneously? Or the thread pool is only for synchronous jobs. 2. Can Cppdb handle asynchronous query? I mean that providing callback at query execution and be called later when query is finished. Maybe this must be handled with cppcms event loop. Is there any example using asynchronous query or it's not possible? 3. What is the difference between running cppcms as multi process mode beside running only single process mode? I found that on windows platform it can't be run as multi process mode. I'm not going to run it on windows for production but is there any other big difference I have to aware? Something like local cache is shared between threads but not shared between processes. Or some performance effect like running 8 processes with single thread mode, or running 1 process with 8 threads. Information about Internal structure about performance would be helpful. 4. Dynamic loading .so files I saw that cppcms highly recommend to use dynamic loading views but I also found that auto update (checking .so file's modification date and auto reloading views) function may affect bad performance. So, dynamic loading views are only good with test mode and static library loading is better for production service? I'm only asking at the aspect of performance. Loading all .so files at startup looks much better for performance. I'm about to load more than 100 .so view files. Thanks in advance. Cppcms looks like well designed and implemented. |

In my opinion the stupidest thing in the C++11 standard is letting the uniform initialization syntax to actually call other constructors. I kinda like the idea of having a different syntax between: "default constructor", "list of initial values", and "another kind of constructor."

Dear list, I am using cppblog for my blog. It is working fine, but I'd like to change some details. I have some problems to do so because I did not understand how the localization works. It is documented somewhere? What should I study? Yours faithfully, Paolo |

I don't understand, the deprecation of std::auto_ptr applies only if you use C++11, if you use C++03 of course it does not apply.

Besides that fact that the stuff you pointed to works with lambdas,.. C++11 compiler support is problematic even if you take the LATEST versions. For example one of the stuff I would also borrow from C++11 is std::regex, std::shared_ptr, and more, but std::regex support for example is broken in both libstdc++ (gcc's) and buggy libc++ (clang's), there are more. So at this point CppCMS is C++11 friendly (and uses some of the stuff like auto in templates) but remains C++2003 compatible. auto_ptr removal/deprecation is one of the stupidest things in C++11. I agree thatstd::unique_ptr is way better but if you work with C++2003 you need auto_ptras only useful standard smart pointer around.

Yes I'm familiar with Valgrind an exceptional tool. The code does not require to lock the LRU mutex - I'll explain. The cache storage is ALWAYS accessed via read-only (multiple lock) or write (unique lock access),for example in store() it is locked at line 354. However for read access which is vast majority multiple threads can access the cache. But LRU updatewith is rather a short part is write access to it has its own lock. Now read and write lock can't be hold simultaneously so LRU is already protected is store by higher level lock. In any case nice to see somebody actually goes as deep as that.

Hi,
are there future plans for C++11/14.
Like a URL-Dispatcher with lambdas or std::function, something like this:
dispatch("/number/(\\d+)", [&](std::string number){
this->number(number); });
dispatch("/foo/(\\d+)/(\\d+)", [&](std::string bar2, std::string bar1){
this->foo(bar1, bar2); });
Switch between smartpointers,
Use CMake to setup?, -DUSE_CPPCMS_STD_PTR=std::unique_ptr,
-DUSE_CPPCMS_STD_PTR=std::auto_ptr,
auto_ptr will maybe removed in C++17.

CppDB (if the backed allows) fetches the data row by row and not the entire collection: Unprepared statements: http://sourceforge.net/p/cppcms/code/HEAD/tree/cppdb/trunk/drivers/mysql_backend.cpp#l75 Prepared statement: http://sourceforge.net/p/cppcms/code/HEAD/tree/cppdb/trunk/drivers/mysql_backend.cpp#l510 cppdb::result is sort of cursor you iterate over the data set. The delay probably caused by initial query and not fetching itself.

Sent: Wednesday, April 1, 2015 12:36 PM Subject: [Cppcms-users] Avoid loading query results completely into cppdb::result Dear Artyom, Dear community, I was wondering if it's possible, to avoid loading the complete query result into cppdb::result but handle the query results "step by step"? If I'm running the following query on a bigger database <code> cppdb::result r = sql << "SELECT name,age FROM students"; </code> it takes a lot of time to copy all the results into the cppdb::result container. For testing I tried that for about 6 mio entries.. I didn't work with the original MySQL-lib yet.. but if I send the query using the standard MySQL lib e.g. <code> res = mysql_perform_query(conn, "SELECT * FROM students"); while ((row = mysql_fetch_row(res)) !=NULL) .... </code> it seems that the interface delivers single rows only, if I'm fetching the result (row by row). Now I was wondering, if there is some technique / flag to do the same with cppdb? In the end I'm trying to run through a big amount of data. If I'm trying offset/limit combinations, it gets very slow as soon as offset increases.. It'd be great, if someone would have a tipp for me.

Dear Artyom, Dear community! Just my 2c: 1. We should migrate to github. Yes, I understand you about already configured svn environment and etc, but github is really powerful and user friendly social platform and I'm sure it'll simplify development process and increase community activity. In the long term it definitely worth the time and effort. 2. I'll be glad to see small releases even with few changes than one big release per 1-2 years.

Before CppCSM 1.0.0 the older version had no this policy and it was problem. If a library releases a security fix with ABI compatibility - you just deploy the libcppcms.so - that's it. Only application restart is required. Consider you have a production site, if you need to release a fix you don't need to redeploy the application. I personally had several cases were I could easily upgrade cppcms and deploy it without caring about multiple applications recompilation. If you have a big and busy site like this [1] it is critical. Another stuff was using boost or some other libraries in API for example - it was horrible-horrible experience: (a) boost breaks its own API & ABI almost every release (!) - your code becomes if-def spaghetti especially when customer needs a specific boost version or runs on older platform (b) boost's ABI can be broken with a simple define, the deployment is major problem especially when some customer's code uses boost as well. There are NUMEROUS cases when applications crashed because different parts were compiled with different versions of Boost - and it was very hard to debug such things(c) I need to support many platforms including Windows, so every library should have wide support of every platform/compiler(d) Today with mix of C++ 2003 and C++ 2011 it is even more critical to keep the ABI stable and independent.

Sent: Friday, March 27, 2015 4:56 AM Subject: Re: [Cppcms-users] Current Develoment I find praiseworthy your dedication to keep cmscpp ABI compatible and the strict policy for external deps, but it is really necessary? Is the userbase so large that doing differently would really break things like in KDE? It absolutely not meant as a critic, I am asking because I don't understand.
