Firebird SQLAlchemy support

Firebird SQLAlchemy status for Firebird Advent 2020

https://qiita.com/advent-calendar/2020/firebird

Current SQLAlchemy release 1.3.20 supports firebird out of the box 

https://docs.sqlalchemy.org/en/13/dialects/firebird.html

In the future the driver is moved outside of SQLAlchemy repository in this place 

https://github.com/pauldex/sqlalchemy-firebird

so it will be installed in the future releases with :

pip install sqlalchemy-firebird

After sqlalchemy and driver install you can follow the official tutorial or something similar using the firebird dialect

django-firebird driver status

Firebird django-firebird driver status for Firebird Advent 2020 

https://qiita.com/advent-calendar/2020/firebird

django-firebird pre released 2.2a1 version with support for Firebird 3 and Django 2.2.x LTS (That will be supported until 2022 according to the roadmap) 

Thanks to this pull request #111.

The stable version corresponds with django 2.2 and live into stable/2.2.x branch. The current master branch of this repository is being developed under django 3.0.x.

fbd is the legacy official driver with support for python 2.x and python 3.x , 

We need to switch to new python3/firebird3.x only driver in the future firebird-driver

So the recommended way today is Django 2.2.x and fdb driver (for Firebird 3.x)

Alternate experimental driver : djfirebirdsql

DJFirebirdSQL is a Django firebird database backend using pure python driver pyfirebirdsql (Work in progress)

https://github.com/nakagami/djfirebirdsql

Requirements: Django 3.1 and Firebird 4.0 beta1 (Firebird 3.0 minimum version required)

Firebird python3 driver status

Firebird python3 driver status for Firebird Advent 2020 

https://qiita.com/advent-calendar/2020/firebird

The firebird-driver package provides driver for Python 3.8+ and Firebird 3+. This driver uses new Firebird OO API provided by fbclient library. You can download it or install directly from Python Package Index.

To use the driver you can start with the Getting Started from documentation area 

A few more examples are in Usage Guide from documentation area

Please note, that his new driver requires Firebird 3+ and Python 3.8+.
This “high” base line was chosen deliberately, to use all new features
available from latest Firebird & Python releases without constraints and
limits that backward compatibility would require. Internally, the driver
uses new client API based on interfaces introduced by Firebird 3. This
new API has many limits raised (like statement sizes, blob sizes etc.)
or completely lifted (like number of databases participating in
distributed transaction), and provides access to new Firebird features
(like scrollable cursors).

The 1.0 release supports all key driver features you know
from FDB (passes all tests for FDB features)

New features in comparison to FDB:
– scrollable cursors
– type hints everywhere
– new FB client API instead old one
– enhanced Enums and Flags classes instead isc_* constants
– better and more rich support for Firebird services

The driver has also much cleaner structure and namespaces, and less core
code than FDB, and although it was not measured yet, it should also
perform better. However, the driver API is not 100% backward compatible
(with FDB).

Please note, that FDB driver is now considered as legacy driver, and its development will be discontinued together with 2.5 once Firebird 4.0 will be released later this year.

The driver uses firebird-base package, which is a collection of modules that have general applicability, like extended configuration, context-driven logging and trace/audit, hooks, work with structured binary buffers, extended data structures etc. The driver uses almost all features provided by "base" package, but specifically the use of hook mechanism and context-driven logging and trace/audit are potentially the most valuable improvements.


The firebird-lib package provides extensions to the firebird-driver.
This package provides modules for:
Work with Firebird database schema.
Work with Firebird monitoring tables.
Processing output from gstat Firebird utility.
Processing Firebird server log.
Processing output from Firebird server trace & audit sessions.

You can download this library from PyPI or or install it using pip.

Python 3 Firebird-driver & Firebird-lib 1.0.0 released

The firebird-driver package provides official Python Database API 2.0-compliant driver. In addition to the minimal feature set of the standard Python DB API, this driver also exposes the new (interface-based) client API introduced in Firebird 3, and number of additional extensions and enhancements for convenient use of Firebird RDBMS. The driver is written as pure-Python package (requires Python 3.8+) on top of Firebird client library (fbclient.so/dll) using ctypes. Driver supports Firebird version 3.0 and higher.

You can download this driver from PyPI or or install it using pip.

Please note, that FDB driver is now considered as legacy driver, and its development will be discontinued together with 2.5 once Firebird 4.0 will be released later this year.

The driver uses firebird-base package, which is a collection of modules that have general applicability, like extended configuration, context-driven logging and trace/audit, hooks, work with structured binary buffers, extended data structures etc. The driver uses almost all features provided by “base” package, but specifically the use of hook mechanism and context-driven logging and trace/audit are potentially the most valuable improvements.

Understanding High Performance

Understanding High Performance via Michael Abrash's Graphics Programming Black Book

"Before we can create high-performance code, we must understand what high performance is. The objective (not always attained) in creating high-performance software is to make the software able to carry out its appointed tasks so rapidly that it responds instantaneously, as far as the user is concerned. In other words, high-performance code should ideally run so fast that any further improvement in the code would be pointless.

Notice that the above definition most emphatically does not say anything about making the software as fast as possible. It also does not say anything about using assembly language, or an optimizing compiler, or, for that matter, a compiler at all. It also doesn't say anything about how the code was designed and written. What it does say is that high-performance code shouldn't get in the user's way—and that's all.

That's an important distinction, because all too many programmers think that assembly language, or the right compiler, or a particular high-level language, or a certain design approach is the answer to creating high-performance code. They're not, any more than choosing a certain set of tools is the key to building a house. You do indeed need tools to build a house, but any of many sets of tools will do. You also need a blueprint, an understanding of everything that goes into a house, and the ability to use the tools.

Likewise, high-performance programming requires a clear understanding of the purpose of the software being built, an overall program design, algorithms for implementing particular tasks, an understanding of what the computer can do and of what all relevant software is doing—and solid programming skills, preferably using an optimizing compiler or assembly language. The optimization at the end is just the finishing touch, however."

Max Transaction ID in Firebird

Firebird 3.0.x introduced 48-bit internal transaction IDs that are publicly (via API and MON$ tables) represented as 64-bit numbers. This makes the new limit roughly equal to 2.8*10^14 transactions, later it could be extended up to the 2^63 limit.

"And my final test as to whether or not Debian succeeded was: could the founder step away from the project and could the project keep going because that is the only point at which you know that the project has basically taken a life of its own." ~ Ian Murdock

C++ the Newest Old Language : presentation by Matt Godbolt (GOTO Chicago 2018)

This presentation was recorded at GOTO Chicago 2018 C++ is an old language only used by the unfortunate few that absolutely have to, right? Wrong! C++ is not the language it used to be: clunky, error-prone and lacking in tooling. A lot has changed in the last decade: three new language revisions, new compilers and all-new: [...] Download slides and read the full abstract here: https://gotochgo.com/2018/sessions/359

In 2017, The Document Foundation (TDF) launched four tenders aimed at improving LibreOffice. Tender four is of interest to the Firebird community

In 2017, The Document Foundation (TDF) launched four tenders aimed at improving LibreOffice. Tender four is of interest to the Firebird community:

(4) Tender to implement HSQLDB binary format import in LibreOffice

(https://blog.documentfoundation.org/blog/2017/05/04/tender-implement-hsqldb-binary-format-import-libreoffice-201705-03/)


Collabora will develop a mechanism to import database files with high fidelity from the HSQLDB binary file format, which has been used inside many existing ODB files, by reading the Java serialization code, and writing a filter to import all data into LibreOffice Base. The objective is to remove the legacy Java/HSQLDB database and move to Firebird.


TDF will invest € 29,750.00

LibreOffice Firebird driver related changes

There were quite a few bugs fixed in the last two months related to Firebird driver in LibreOffice also interesting commits

Tamas Bunth commited : Add HSQLDB schema import.
He also fixed Bug 104734 - FIREBIRD: Add those field types that are not available with FB while they are available with Hsqldb.
Lionel Elie Mamane fixed Bug 104986 - Firebird: Function EXTRACT doesn't work with WEEKDAY, YEARDAY, MILLISECOND.

Tor Lillqvist fixed Bug 71007 - EDITING: Embedded Firebird - Impossible to set milliseconds in a timefield with GUI

Tamas Bunth fixed Bug 70425 - EDITING: Embedded Firebird - Copying integer values from Calc to Base impossible

For this project, as ever, we need funding. This is your opportunity to make it happen, by contributing whatever you can to our crowdfunding campaign.

HSQLDB binary format import

Tender approved in the budget by the TDF board


In order to remove the legacy Java / HSQLDB database completely, and move fully to Firebird in LibreOffice 5.4 it is necessary to be able to import old document data with high fidelity from the HSQLDB binary file format which we have used (for performance) inside so many of our existing ODB files. This task involves reading the existing (reasonably simple) Java serialization code, and writing an (import only) filter to import this data safely into base.

LibreOffice bug #106866 is now fixed : When I change the field length of the result is multiplied by 4 each time (firebird, varchar)

Bunth Tamás committed a patch related to issue #106866: query character size instead of bytes

It has been pushed to "master":

It will be available in 5.4.0. The patch should be included in the daily builds available at 

http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours.

More information about daily builds can be found at: http://wiki.documentfoundation.org/Testing_Daily_Builds 

Affected users are encouraged to test the fix and report feedback.

Firebird bug CORE-5452 is fixed : Segfault when engine's dynamic library is unloaded right after closing worker threads

Firebird bug CORE-5452 is fixed http://tracker.firebirdsql.org/browse/CORE-5452

The issue was reported multiple times in Firebird devel list, I will mention here Damyan Ivanov (Debian) and Stephan Bergmann. (RedHat)

And related commit in Firebird 3.0 branch

https://github.com/FirebirdSQL/firebird/commit/40f782ae3e918c4f3842571ff8064be1c4f54961

Stephan Bergmann contributed the patch to LibreOffice in external/firebird

LibreOffice bug #103074 : Implement Boolean Type for Firebird driver is now fixed

Bunth Tamás committed a patch related to issue #103074 : Implement Boolean Type for FB driver .
It has been pushed to "master":

It will be available in 5.4.0.

The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
information about daily builds can be found at:

Affected users are encouraged to test the fix and report feedback.

ps:
From the list a of Firebird integration blockers there are only a few left

Listed blockers:

   70425: EDITING: Embedded Firebird - Copying integer values from Calc to Base impossible  See dependency tree for bug 70425
   70506: EDITING: Embedded Firebird - Alias in queries are ignored  See dependency tree for bug 70506
   104316: FIREBIRD 3 : attempting to open a Firebird 3 embedded ODB database file fails to draw all UI elements, causes general LibreOffice UI malfunction

Firebird 3 by default in LibreOffice 5.4

Lots of missing features & big bugs were fixed recently .
All of the blockers that were initially mentioned on tracking bug are now fixed.

Lionel mentioned that he added a few more blockers that needs to be fixed until Firebird will be switched by default :

I went over
https://bugs.documentfoundation.org/buglist.cgi?quicksearch=firebird

and added a few open bugs to the blocker bug
https://bugs.documentfoundation.org/51780

based on their description (and NEW instead of UNCONFIRMED status)
only, without reading the bug log in great detail.

Tamás Bunth (Wastack) agreed that 6 months time frame is more than enough to fix bugs that will appear

I agree, it would be reasonable to wait a half year. Until that we can
fix the already found and the upcoming bugs, solve the backward
incompatibility. Even if those can be solved quickly we can upgrade to
the c++ API. 

Another issue is importing old hsqldb databases without java installed

It requires making a read-only parser for the HSQLDB "cached" table
data format in another language than Java. Most definitely possible,
the format may even be better documented than "read the source code".

Service for migrating Firebird 2.5 format to Firebird 3.0

On Libreoffice Devel there is a thread about migration of the already created odb files with 2.5 databases inside (fdb) but also about the forward and backward compatibility of the Firebird backup archive (fbk).
https://lists.freedesktop.org/archives/libreoffice/2016-November/075953.html

Lionel added notes about upgrading in the wiki :

People trade privacy for convenience or the other way round all the time. People that in this case favor convenience can use the hypothetical web service. People that favor privacy can follow the instructions at
https://wiki.documentfoundation.org/Development/Base/FirebirdSQL#Older_Firebird_databases(which the web service should point towards for information).While I'm not exactly lobbying for this web service, we are a volunteer-driven organisation and if Tamás feels like doing it, all the merrier.

Lionel Elie Mamane committed a patch related to this issue tdf#101789 : Firebird 3 - fails to build on OSX 10.11.x with clang

Lionel Elie Mamane committed a patch related to this issue tdf#101789 Firebird 3 - fails to build on OSX 10.11.x with clang.

It has been pushed to "master": tdf#101789 work around DYLD_LIBRARY_PATH limitations on newer MacOS X.

An alternative fix has been in place ever since Stephan Bergmann commit " Allow external/firebird to be built with a custom SHELL under Mac OS X 10.11".

Bunth Tamás commited a few patches related to Firebird driver

Tamás committed a patch related to tdf#74172 issue.
Ensure prepared while setting numeric
It has been pushed to "master":
It will be available in 5.3.0. The patch should be included in the daily builds available at http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours.

Affected users are encouraged to test the fix and report feedback.

Another commit is just code refactoring : get table name from resultset simply. There is a much simpler way to access table name in ResultSetMetadata in Firebird sdbc.

Bunth Tamás commited a patch for LibreOffice bug #74172 : use DECIMAL and NUMERIC data types

 Bunth Tamás commited  a patch for bug #74172 use DECIMAL and NUMERIC data types

Firebird 3.0 is released

Firebird Project is happy to announce general availability of Firebird 3.0 — the latest major release of the Firebird relational database.

The primary goals for Firebird 3.0 were to unify the server architecture and to improve support for SMP and multiple-core hardware platforms. Parallel objectives were to improve threading of engine processes and the options for sharing page cache across thread and connection boundaries.

Alongside these aims came new strategies to improve performance, query optimization, monitoring and scalability and to address the demand for more security options. A number of popular features were introduced into the SQL language, including the long-awaited support for the Boolean data type and the associated logical predications.

Read the Press Release for more information. Please refer to the Release Notes for the full list of changes. Binary kits for Windows and Linux on both 32-bit and 64-bit platforms are immediately available for download. MacOS X and other platforms will follow.

Firebird 3 final is about to be released

The source code was just tagged in the repository, so we can expect the final release being out in the next days.

One change in the new Firebird 3 OO examples api is addition of the Services example .

Good news : Firebird 3.0 builds and works now with libreoffice

It was the comments that I forgot in download.lst (I forgot to comment 2.5.5 and enable 3.0).

I have updated the patch and now it compiles fine on ubuntu 15.10 x64
https://gist.github.com/mariuz/bcde7f783b657b2465e5

Submited new gerrit
https://gerrit.libreoffice.org/23737



Here is manual test :)

Icu error with Firebird 3.0 patch , testing lode script

I started refactoring firebird 3.0 patch and there are few issues with icu linking.
There are is no more --with-system-icu from the firebird configure options (Firebird on posix is using system icu : there is no icu no more in firebird tree).

So firebird is using the icu from libreoffice folder (downloaded to build libreoffice)
I will try to compile libo with --with-system-icu

On Windows 10 i started testing the lode script for setting up libo development 

Firebird 2.5 Patch to compile with Visual Studio 2015

Final Firebird 2.5 Patch to compile with Visual Studio 2015 is now merged
https://github.com/FirebirdSQL/firebird/pull/12

I will add a gerrit for libreoffice also https://patch-diff.githubusercontent.com/raw/FirebirdSQL/firebird/pull/12.patch

Gerrit for this patch is now created and added Lionel to the reviewers

https://gerrit.libreoffice.org/#/c/23738/


update: added patch with mod_loader changes for VC14 ,
removed external/firebird/firebird-vs2013.patch.1 is not needed anymore in 2.5.5 (applied upstream) ,

modified UnpackedTarball_firebird.mk apply firebird-msvc14.patch.1 only on Windows

ps: in Firebird tree i will send a pull request with icu small changes needed also new solutions for VS 2015 were merged earlier

Firebird 3.0 and MSVC14 build (good news)

I have tested the Firebird 3.0 and MSVC14 compiler and builds ok

https://github.com/FirebirdSQL/firebird/tree/B3_0_Release/builds/win32/msvc14


Tomorrow I will test also with firebird 2.5.x branch and i will check what patches are needed

Instructions for building it are located here

https://github.com/FirebirdSQL/firebird/blob/master/doc/README.build.msvc.html

and on the website

http://www.firebirdsql.org/en/building-the-code/

Let's go back to the c , Firebird embedded backup service works

I have used an c based example for services api and seems that it works without a need for auth user



gcc backup_service.c -lfbembed

./a.out employee.fdb employee.fbk

Attach succeed

Start succeed

gbak:readied database employee.fdb for backup gbak:creating file employee.fbk

...

gbak:writing SQL roles gbak:writing names mapping gbak:closing file, committing, and finishing. 74752 bytes written

I will split the backup service function in two one for backup and one for restore then i will compare with my service example , maybe is a buffer truncation issue

Update firebird to version 2.5.4 is applied into LibreOffice master

There was a small issue with tinderbox and was reverted and then re-applied to master.

Rebuilding of indexes function is now removed from master (Using firebird backup format for .odb there is no need for rebuild indexes).

JDK issues on OSX , ran the tests without Java

To run all the dbaccess tests On OSX I had to install jre 6 then jdk/jre 8 but still
dbaccess tests wouldn't run java popup still appeared even if the java -version showed
the proper 8 version , so for the moment i have disabled the java tests

./autogen.sh --without-java

Update: Tests are finished and Firebird 2.5.4 update patch on gerrit is up for review
https://gerrit.libreoffice.org/16703

Tested on OSX 10.10.4 , Win 10 , Ubuntu 14.04
