I made a mistake when posting to Gist. I made a slight tweak to the code when posting, and forgot to check if it worked. (Rookie mistake, I know). The error that you are seeing in the first case is not related to threading at all; it is just a bad pointer. Will you please humor me and try one more time with the updated code? https://gist.github.com/nispio/fe2955c9a0978532cf7b864a8b1b54db |

Using additional platforms allows you to catch some important stuff. - BSD is quite popular platform that CppCMS runs well on it (same for Solaris also less popular than BSD) - Finally there is Mac OS X (that is quite close to BSD) and I can't run Mac OS X VM for testing due to licensing restriction. The bugs are small and should be quite fixable - in any case this isn't the main reason the release is delayed.

I have another question. Why are you trying to support BSD and Solaris? Linux is good enough and we can skip other Unix stuff. I have not tried to look at CppCMS source code. I just use it. Seems I can help some but I am also busy writing my books. If I manage sometime I will try to send some patches say after 3 months. What format do you accept patches in?

First of all I suggest to use trunk - it is very stable. I think many users are switched to trunk. Indeed I need to release the new version. And fix this: http://cppcms.com/wikipp/en/page/cppcms_1x_tasks#Update.external.modules.to.updated.API Additionally I still have some unit test fails on BSD and Solaris I need to resolve: http://cppcms.com/files/nightly-build-report.html Unfortunatelly I can't commit to a specific time.

Using single connection created out of sequence error! IN fact the use of new connection works properly as sqlite3 does not support writing the same database from different threads simultaneously and would return the error the locked database and user need to handle such a error - i.e. try to run the statement same time - similarly that in "bigger" DB you receive deadlock errors. In fact you try the test with sqlite3 in exact situation where the sqlite3 is suboptimal - high concurrency updates. https://sqlite.org/whentouse.html If you for example run select queries in all threads it would succeed and if you turn on WAL you would likely succeed doing simultaneous single write multiple reads. Bottom line - sqlite3 behaves exactly as expected. You probably misunderstand the use case. If you want to run high amount of inserts to DB the optimal way is to do it from a single thread in a single transaction (on Rollback journal mode) or from single thread in big chunks each in a single transaction of WAL mode. In any case you have to be ready to handle errors - similar to the way you need to handle deadlocks in "big" DBs.

I have created a stand-alone test that shows the difference between sharing a single SQLite database connection between threads, and creating a new connection for each thread.

Hi Artyom, Can you please tell us when would you be able to release code lying in trunk? I know you are busy with job and family but it would be very kind of you to do a new release. -- Respect, Shiv Shankar Dayal |

Hello Mawan This has been discussed before and you can find more help in the history of this group. Generally you can read this in the documentation http://cppcms.com/wikipp/en/page/cppcms_1x_tut_web_server_config On Wed, Jan 11, 2017 at 12:32 PM, mawan sugiyanto <ma...@gm...> wrote: > Dear All > > When i upload and config web app as cgi , css file, js can not load from > web server.

The problem with the number of rows is that in many APIs it isn't known in advance. For example sqlite3 and mysql fetches row by row until you get to the end of the query. You can store the entire result but it may be costly - and it isn't done by default. So the number of rows in advance can be used for only in limited set of drivers.

I'm sorry, let me attempt to express myself more clearly: A given process may share a *single* connection to the database between multiple threads. In other words, the call to sqlite3_open_v2() should only happen once within a given process, and all threads within that process should then utilize that single connection, so long as it is open. The way in which SQLite supports multi-threading is via its own internal mutexes. However, creating multiple database connections to the database (via multiple calls to sqlite3_open_v2) will cause multiple mutexes to be created, therefore nullifying their usefulness. The SQLite FAQ says the following: >> SQLite is threadsafe because it uses mutexes to serialize >> access to common data structures. I am not suggesting that multi-threaded access cannot be achieved with SQLite. I am suggesting that the correct way to do multi-threading with SQLite is to create a single database connection within a given process, and share that connection between the threads. This allows the internal mutexes in SQLite to work as intended. I have tested this, and can provide test code to demonstrate SQLite behavior, if desired. |

Hi! If there are people being able to arrange time to enhance CppDB to return the selected rows count from cppdb::statement::query(), maybe I can take the PostgreSQL part. I can't do this alone because I know nothing except PostgreSQL :-( Best Regards, CN -- http://www.fastmail.com - Access all of your messages and folders wherever you are |

If that is the case, then the cppdb_sqlite3 driver is written contrary to the intended usage of sqlite3. It seems that the right thing to do may be to open a single connection and share it between the threads. |

In general sqlite3 behaves poorly with multiple threads and you should make yourself ready to deal with the issue - simultanious updates and even query + update may fail.
