Add user plugins infrastructure

Add user plugins infrastructure which should replace custom scripts implemented a2bf0ed .

The idea is to have some plugins directory in 'user/plugins/client|server' which should contain scripts which will be automatically executed. 'user/plugins/client' could probably contain LTSP plugins.

Add LDAP authentication support

• install OpenLDAP server on GIS.lab server
• add parameter -s to 'gislab-adduser' script which will add user to 'labadmins' LDAP group. If not given, add user to 'labusers' group. If user is in 'labadmins' group allow 'sudo' on server and on clients.
• add LDAP logic to 'gislab-adduser' and 'gislab-deluser' scripts. Source LDAP functions from 'ldapscripts/lib/runtime'
• add script 'gislab-password' which will change user password new password (without asking current password). If parameter '-p' given change to given password, if not generate random new password (similar to 'gislab-adduser )
• define variables $USER, $PASSWORD, $UID, $GID and use them in 'gislab-add|deluser' and 'gislab-password'
• use only encrypted LDAP connection
• authenticate following services using LDAP credentials: Linux login (pam) on server and clients, PostgreSQL, QGIS connection to PostgreSQL.

Add full backup and restore tools

• add variable GISLAB_BACKUP_DIR in config.cfg and create it if not exists in installation
• add 'gislab-backupuser' script which will create following backup files in config.$GISLAB_BACKUP_DIR/gislab-backup-$USER-YYYY-MM-DD:HH-MM-SS
  ** home file excluding hidden files in home.tar.gz
  ** shared files in share.tar.gz
  ** objects in 'gislab' PostgreSQL db under user's schema
• add 'gislab-restoreuser' which will delete user as a first step ad restore files

To implement this feature we need add possibility to install VirtualBox additions to client image. Additions must match client VirtualBox version.

WebGIS - add a possibility to manage a history of saved drawings

WebGIS - add a possibility to list history of saved drawings to 'Drawings History' panel .
Content: time, Drawing ID, Permalink

• when loading DRAWING add download hyperlink in to toolbar
• move DRAWING hyperlink to bottom panel

• how to use built in chat service
• how to create map project and publish to WebGIS (QuickStart)
• how to use base maps (OSM, Google ...) in QGIS and in WebGIS

...

Secure ssh keys and password for vagrant user account

Secure ssh keys and password for vagrant user account. Also remove Ubuntu account.

WebGIS - add feature search support

WebGIS - add feature search support using WMS GetFeatureInfo request

Example:
http://localhost/wms/helloworld?SERVICE=WMS&VERSION=1.1.1& REQUEST=GetFeatureInfo&LAYERS=Country&QUERY_LAYERS=Country& FEATURE_COUNT=10&INFO_FORMAT=text/xml&SRS=EPSG:4326& FILTER=Country:"name"+=+'africa'

Restrict concurrent logins from the same client

Restrict concurrent logins from the same client.

Look at LDM_LIMIT_ONE_SESSION = True LDM_LIMIT_ONE_SESSION_PROMPT=True in lts.conf

Preinstall some useful QGIS plugins

Preinstall some useful QGIS plugins like OpenLayers.

Here is some docs to plugins repository: http://www.qgisworkshop.org/html/workshop/repositories.html

'bad_alloc' error at QGIS start

Sometimes QGIS throws error message 'std::bad_alloc' just after QGIS window is started. It seems to be upstream problem and is reported in QGIS bug tracker [1].

1 - http://hub.qgis.org/issues/9213

Add GIS.lab QGIS plugin

Add GIS.lab QGIS plugin which could help with tasks like:

• open current project in WebGIS

Use Ansible for server provisioning

Use Ansible for server provisioning

Configuration file cleanup

Configuration file (config.cfg) cleanup. This file needs some better structure.

WebGIS - rewrite application to Django

WebGIS - rewrite application to Django

Structure:
gislab-webgis

• webgis
  • viewer
    views: page, featureinfo
  • storage
    models: Ball (add timestamp field)
• move variables from apache.conf to settings.py (update apache.conf)

WebGIS - add support for custom base WMS layers

• add new GET parameters BASE which will accept list of layers which should be used as base layers. These layers should be used beside OSM and Google layers.
• informations about layer title, type, provider ... should be taken from GetProjectSettings request which must be extended to contain them (see http://lists.osgeo.org/pipermail/qgis-developer/2014-February/030743.html)

Adding values to GetProjectSettings request is a task of #95 .

Use strong user passwords

Currently GIS.lab is using 'lab' password for all user accounts.

Add optional possibility to specify password to 'gislab-adduser' script which will serve for automatic accounts creation at start with 'lab' password. Otherwise script will generate random password.

Plugins does not correctly support user accounts settings

Plugins does not correctly support user accounts settings.

To fix:

• create backup of /etc/skel before first user accounts creation and restore it always from that backup
• add plugins support also to gislab-adduser script

WebGIS - read QGIS project settings from GetProjectSettings request

We can read many useful informations from GetProjectSettings request:

• layers visibility status
  ...

Reduce server logs verbosity

Reduce server services logs verbosity in non-debug mode.

Disable Plymouth

Disable Plymouth on server and also on client.

See: http://virtual-drive.in/2012/05/20/ubuntu-12-04-text-boot/

WebGIS - better project capabilities error handling

Add better WMS GetCapabilities request error handling.

Add full data capturing capabilities to WebGIS

Add possibility to capture points, lines and polygons and send them via Permalink.

To implement this feature we need to:

Create small server application (proposed name 'balls')

• which will save captured geometries on POST request (in GeoJSON text format) with returned unique ID
• return saved data by GET request

POST: balls.gis.lab/
Response: ID

GET:balls.gis.lab/?ID=(ball ID)
Response: data in GeoJSON format with GeoJSON MIME type

Update WebGIS application.

• add possibility to capture polygon and line objects
• change behavior of 'export' tool to save captured geometries to 'balls' and return GeoJSON file ((ball ID).geojson) to download
• update 'permalink' to save remove POINTS parameter and add BALLS instead. It would be fine to be able to specify multiple comma-separated ball IDs in BALLS parameter.

WebGIS - add layers category support

WebGIS - add layers category support, but keep loading visible layers in one request.

Creation of video presentation how to build a GIS network using GIS.lab

Video should explain:

• what one needs to do to create similar network using other tools
• how to use GIS.lab unit (Mini PC) to create LAN and start using it

WebGIS - add print support

Add QGIS server print support to WebGIS app.

Print dialog should allow to choose:

• Title
• Print template
• DPI
• Rotation
• Bounding box rectangle should allow to be moved in map

WebGIS - add possibility to update existing drawing

Add possibility to update existing drawing.

Creation of detailed 'Quickstart' document

• Create step-by-step tutorial with screen shots how to install GIS,lab on Windows, Linux and Mac
• Create step-by-step tutorial how to create first GIS project and publish in WebGIS.

Publish both documents on project's wiki page.

File manager can not delete files in shared dirs

File manager can not delete files in shared dirs because it can not bypass moving files to 'Trash'.

Solution is to use SHIFT-DEL or create custom command "rm -rf %F" [1].

Upgrade PostGIS version 2

Upgrade PostGIS version 2 and rebuild also SpatiaLite package with lwgeom support.

Use secure SSH key on GIS.lab server

Use secure, user specified SSH key on GIS.lab server instead of Vagrant's default keys. Restrict SSH login by plain password.
