With fdb version 1.4.4 we recommend flynn.io open source platform as a service (PaaS)

Here is is how it works now with django-firebird and heroku buildpacks

Egor Pugin announced on Firebird-Devel list :

With new CMake 3.2.1 it is possible to successfully build Firebird for
iOS platform using CMake.
Updated instructions for iOS build available at
https://bitbucket.org/egor_pugin/firebird_cmake/wiki/Home

The last issue you encounter during building is duplicate symbol error
from clang. It is related to class DatabaseDirectoryList in anonymous
namespace. This class exists in files: src/jrd/jrd.cpp and
src/common/db_alias.cpp.
For my tests I added last underscore symbol to one of those classes
and the build completes.

node-firebird 0.6.0 released with critical problem with Transactions fixed

There is a medium difficulty task for a c++ programmer in current GSOC 2015

The Firebird driver for LibreOffice was started, and is mostly functional, in a previous GSoC, but it needs finishing and polishing. The main remaining issue is that the firebird data format embedded in the .odb file is endianess-dependent. The idea is to switch to Firebird’s “archive” format that is not.

Required skills / knowledge
C++, SQL, Reading other’s code, capacity to work autonomously.

Roman Simakov announced BenchmarkSQL for Firebird
I’ve ported BenchmarkSQL for Firebird. It’s TPC-C test working via
JDBC and support PostgreSQL, Oracle, DB2 and now Firebird.

I could run it locally and maybe it could be useful to know where we
are comparing to other DBMSs.

Please share you investigations.

Adriano dos Santos Fernandes (on the Firebird Development list): “I just built an example of Firebird 3 API usage with FreePascal. As said earlier, working with input/output buffers directly in non-C/C++ is difficult. This requires auxiliary classes. The others things seem ok and easy to use. We need some new functions in the new API, for example, to convert.” status vectors to strings, but this is not specific to Pascal.

node-firebird 0.5.1 released with the following functions implemented for Service Manager:

backup
restore
fixproperties
serverinfo
database validation
commit transaction
rollback transaction
recover transaction
database stats
users infos
user actions (add modify remove)
get firebird file log
tracing

List of functions implemeted :

// each row : fctname : [params], typeofreturn
var fbsvc = {
    "backup" : { [ "options"], "stream" },
    "nbackup" : { [ "options"], "stream" },
    "restore" : { [ "options"], "stream" },
    "nrestore" : { [ "options"], "stream" },
    "setDialect": { [ "database","dialect"], "stream" },
    "setSweepinterval": { [ "database","sweepinterval"], "stream" },
    "setCachebuffer" : { [ "database","nbpagebuffers"], "stream" },
    "BringOnline" : { [ "database"], "stream" },
    "Shutdown" : { [ "database","shutdown","shutdowndelay","shutdownmode"], "stream" },
    "setShadow" : { [ "database","activateshadow"], "stream" },
    "setForcewrite" : { [ "database","forcewrite"], "stream" },
    "setReservespace" : { [ "database","reservespace"], "stream" },
    "setReadonlyMode" : { [ "database"], "stream" },
    "setReadwriteMode" : { [ "database"], "stream" },
    "validate" : { [ "options"], "stream" },
    "commit" : { [ "database", "transactid"], "stream" },
    "rollback" : { [ "database", "transactid"], "stream" },
    "recover" : { [ "database", "transactid"], "stream" },
    "getStats" : { [ "options"], "stream" },
    "getLog" : { [ "options"], "stream" },
    "getUsers" : { [ "username"], "object" },
    "addUser" : { [ "username", "password", "options"], "stream" },
    "editUser" : { [ "username", "options"], "stream" },
    "removeUser" : { [ "username","rolename"], "stream" },
    "getFbserverInfos" : { [ "options", "options"], "object" },
    "startTrace" : { [ "options"], "stream" },
    "suspendTrace" : { [ "options"], "stream" },
    "resumeTrace" : { [ "options"], "stream" },
    "stopTrace" : { [ "options"], "stream" },
    "getTraceList" : { [ "options"], "stream" },
    "hasActionRunning" : { [ "options"], "object"}
}

this is an example to use with stream and object

fb.attach(_connection, function(err, svc) { 
    if (err)
        return;
    // all function that return a stream take two optional parameter
    // optread => byline or buffer  byline use isc_info_svc_line and buffer use isc_info_svc_to_eof
    // buffersize => is the buffer for service manager it can't exceed 8ko (i'm not sure)

    svc.getLog({optread:'buffer', buffersize:2048}, function (err, data) {
            // data is a readablestream that contain the firebird.log file
            console.log(err);
            data.on('data', function (data) {
                console.log(data.toString());
            });
            data.on('end', function() {
                console.log('finish');
            });
        });

    // an other exemple to use function that return object
    svc.getFbserverInfos(
            {
            "dbinfo" : true,
            "fbconfig" : true,
            "svcversion" : true,
            "fbversion" : true,
            "fbimplementation" : true,
            "fbcapatibilities" : true,
            "pathsecuritydb" : true,
            "fbenv" : true,
            "fbenvlock" : true,
            "fbenvmsg" : true
        }, {}, function (err, data) {
            console.log(err);
            console.log(data);
        }); 
});
