kd2org/karadav: Lightweight NextCloud compatible WebDAV server
▻https://github.com/kd2org/karadav
https://github.com/kd2org/karadav/blob/main/doc/scr_index.jpg?raw=true

This is a simple and lightweight #WebDAV server, allowing to easily set up a #file_sharing server compatible with WebDAV and #NextCloud clients. It has no dependencies and good performance.

It is written in #PHP (8+). The only dependency is #SQLite3 for the database.

Its original purpose was to serve as a demo and test for the KD2 WebDAV library, which we developed for Paheko, our non-profit management solution, but it can also be used as a simple but powerful file sharing server.

If you are looking for an even lighter WebDAV server, try also our other server, PicoDAV ▻https://github.com/kd2org/picodav. It isn’t compatible with NextCloud/ownCloud clients, but it is a single file that you can drop anywhere in your document root, nothing to install!

loupe-php/loupe: A #fulltext #search engine with #tokenization, #stemming, #typo_tolerance, #filters and #geo support based on only #PHP and #SQLite.
▻https://github.com/loupe-php/loupe

An SQLite based, PHP-only fulltext search engine.

Loupe…
–…only requires PHP and SQLite, you don’t need anything else - no containers, no nothing
–…is typo-tolerant (based on the State Set Index Algorithm and Levenshtein)
–…supports phrase search using " quotation marks
–…supports filtering (and ordering) on any attribute with any SQL-inspired filter statement
–…supports filtering (and ordering) on Geo distance
–…orders relevance based on a typical TF-IDF Cosine similarity algorithm
…auto-detects languages
–…supports stemming
–…is very easy to use
–…is all-in-all just the easiest way to replace your good old SQL LIKE %...% queries with a way better search experience but without all the hassle of an additional service to manage. SQLite is everywhere and all it needs is your filesystem.

LE script miraculeux pour la conversion sqlite > sql
NB : ne pas oublier de faire un rechercher/remplacer pour virer les chaînes COLLATE NOCASE et COLLATE BINARY avant de lancer l’import du fichier SQL obtenu.
...et ne pas oublier de remettre le AUTO_INCREMENT sur tous les champs id_<objet> qui sont les clés primaire des tables spip_<objet>

mysql - How to create ENUM type in SQLite ? - Stack Overflow
▻http://stackoverflow.com/questions/5299267/how-to-create-enum-type-in-sqlite/17203007

les réponses 2 et 3 donnent deux possibilités pour simuler le fonctionnement d’une colonne #MySQL de type #ENUM en #SQLite :
– utilisation d’une table stockant les valeurs d’ENUM et de la contrainte #REFERENCES sur la colonne
– utilisation de la contrainte #CHECK sur la colonne

“The latest #SQLite 3.8.7 alpha version is 50% faster than the 3.7.17 release”
▻http://permalink.gmane.org/gmane.comp.db.sqlite.general/90549

Each micro-optimization might improve the performance
by as little as 0.05%. If we get one that improves performance by 0.25%,
that is considered a huge win. Each of these optimizations is unmeasurable
on a real-world system (we have to use cachegrind to get repeatable
run-times) but if you do enough of them, they add up.

Phinx
▻http://phinx.org

Phinx allows developers to alter and manipulate databases in a clear and concise way. It avoids the use of writing SQL by hand and instead offers a powerful #api for creating migrations using #php code.

▻http://docs.phinx.org/en/latest/configuration.html

Phinx currently supports the following database adapters natively: #mysql, PostgreSQL, #sqlite, SQL Server

Grosso merdo c’est l’API SQL de #SPIP ^^

Réparer une base de données #sqlite foireuse : checker la base avec PRAGMA integrity_check + dumper la base en sql + nettoyer le dump sql si nécessaire + importer le dump sql dans une nouvelle base sqlite = et zou :)

Au secours : j’ai un site sous SPIP en SQLite, j’effectue une sauvegarde sous SPIP (qui m’a l’air correctement formatée). Maintenant comment je fais pour installer ça dans un SPIP sous mySQL ?

VirtualPG: VirtualPG
▻https://www.gaia-gis.it/fossil/virtualpg/index

VirtualPG is a loadable dynamic #extension to both #sqlite and SpatiaLite. Its intended scope is supporting direct SQL access to #postgresql and PostGIS own tables, so to make any possible kind of data exchange between these two popular open source Spatial DBMSes as straightforward and simple as possible.

#Adminer is a full-featured database management tool written in PHP. Conversely to #phpMyAdmin, it consist of a single file ready to deploy to the target server. #mysql #sqlite

SpatiaLite : SpatiaLite
►https://www.gaia-gis.it/fossil/libspatialite/index

SpatiaLite is an open source library intended to extend the SQLite core to support fully fledged Spatial SQL capabilities.

(...)

SpatiaLite is smoothly integrated into SQLite to provide a complete and powerful Spatial DBMS (mostly OGC-SFS compliant).

Ce pourrait être une piste pour rendre #gis utilisable avec #sqlite, par exemple sous #spip. La libspatialite3 est dispo sous #debian.

phpliteadmin - PHP-based admin tool to manage SQLite databases - Google Project Hosting
►http://code.google.com/p/phpliteadmin

phpLiteAdmin is a web-based #SQLite database #admin tool written in #PHP with support for SQLite2 and SQLite3. Following in the spirit of the flat-file system used by SQLite, phpLiteAdmin consists of a single source file, phpliteadmin.php, that is dropped into a directory on a server and then visited in a browser.

Premières impressions après quelques essais avec #SPIP3 et ses bases SQLite :

+ installation simple : fichier à la racine, l’éditer et changer 2 variables sous la ligne 35 : $password = « blabli » ; et $subdirectories = true ; => appeler le fichier, il scanne l’arborescence (vu sur mutu SPIP ;-) ), demande le mot de passe et zou...
+ édition de la base sqlite : OK

– export SQL pas utilisable pour réinjecter en MySQL avec phpmyadmin ;
– import/export en général, rien n’a abouti. C’est chatouilleux ces formats.
