For some unknown reason, font-mfizz was showing the slonik icon in
italic. Even after upgrading it to the latest version of font-mfizz, the
problem was not resolved.
So - instead of using the vector font, using the PostgreSQL SVG logo as
the application icon, and documentation link on dashboard now.
Ship the web code using server mode with appropriate paths by default and enable the runtime to override the mode, and force into desktop changing the appropriate paths to user-specific ones.
Note that this change will likely cause more advanced users to have to tweak configs.
RPMs will also need changes to create /var/lib/pgadmin and /var/log/pgadmin, owned by the webserver account.
In order to resolve the non-ascii characters in path (in user directory,
storage path, etc) on windows, we have converted the path into the
short-path, so that - we don't need to deal with the encoding issues
(specially with Python 2).
We've resolved majority of the issues with this patch.
We still need couple issues to resolve after this in the same area.
TODO
* Add better support for non-ascii characters in the database name on
windows with Python 3
* Improve the messages created after the background processes by
different modules (such as Backup, Restore, Import/Export, etc.),
which does not show short-paths, and xml representable characters for
non-ascii characters, when found in the database objects, and the file
PATH.

Turns out using the config file isn't a good idea if users copy config.py to config_local.py, as it prevents upgrades to the database. This has the added side-effect of simplifying future changes, as you only need to edit 2 files to modify the config DB now, not 3.
slower system - user may need to set the value to some higher value.
This value decide - for how long SQLITE operation will wait, before
throwing an operation timeout error because of the locked database.
Fixes#1329
A distro can now install a config_distro.py file alongside config.py
in which distro-specific configuration settings can be set, overriding
those in config.py. User settings in config_local.py will override
all other settings. This is useful to allow packagers to config
settings like the doc path, that may be specific to RPMs or Wheels
etc.
inaccessible.
In stand (without threaded) mode, flask application is not able to
process more than one request at a time. Hence - even the client
(browser) send multiple request, when connecting the server (which is
inaccessible), rest of operations get blocked, as making the connection
with the database server is blocking operation.
In order to fix the issue, we're starting the application with thread
support, in which it will create a separate thread of each request.
We will be using the external utilities like pg_dump, pg_dumpall,
pg_restore in background. pgAdmin 4 can be run as a CGI script, hence -
it is not good idea to run those utility in a controlled environment.
The process executor will run them in background, and we will execute
the process executor in detached mode.
Now that - the process executor runs in detached mode, we need an
observer, which will look at the status of the processes. It also reads
output, and error logs on demand.
Thanks - Surinder for helping in some of the UI changes.
selection, creation, upload/download files/directories resides on the
server side.
This will be useful for file selection/creation for different server
side utilites like pg_dump, pg_dumpall, pg_restore.
While accessing the configuration database from multiple session, it
results in to the error - OperationError, because - sqlite locks all the
database, and does not allow to access it simultaneously. We added the
timeout to give some time window for accessing it simultaneously.
server connection.
The BaseDriver and BaseConnection are two abstract classes, which allows
us to replace the existing driver with the currently used. The current
implementation supports to connect the PostgreSQL and Postgres Plus
Advanced Server using the psycopg2 driver.
(lazy loading) using the require.js. This allows us to load the
javascript required for any node, only when it was loaded in the browser
tree. Also, introduced the mechanism to show/edit/create of any node in
a tab panel (wcDocker.Panel).
This allows us to update the configuration database schema as needed,
and use the setup script to update it to the current version.
NOTE: Existing databases will need to be recreated once following
this commit. It doesn't seem worth handling the "upgrade from v0"
case when I'm probably the only active developer right now.
This commit adds the following:
- Storage of server groups in the configuration database
- Creation of a default server group on in the database
- A mechanism for plugging in treeview node types
- A node type for server groups with:
- Treeview display
- Custom per-node javascript implementing a menu option/dialogue to add new groups
- Custom per-node CSS to style the treeview node
- JSON formatted data in response to AJAX requests, including:
- Success/failure indication
- Error message
- Extra info (e.g. stack trace)
- The original request data
- Additional return data, e.g. node ID and label etc.
This adds bootstrap-dialog to help with creation of nice dialogs,
and adds the ability for modules to render Javascript into the
browser, and specify onclick handlers in the menu system.
Also add a basic About dialog, using the new infrastructure and
showing some useful info about the application.
This uses a single default user in the config database, which is
auto-logged into the app when SERVER_MODE = False. In this mode we
also hide/remove user-related functions in the UI.
A user authentication module based on flask-security is added, which
allows users to login and change/recover passwords etc. Custom templates
are included for the user/password UIs.
A new setup script will initialise the user (and later settings) DB,
adding the first user and granting them an Administrator role.
A redirects blueprint module is added to handle simple URL redirects.
A browser module is added and currently renders a skeleton page with
a menu bar, gravatar and jumbotron.
NOTE FOR LATER: Currently this code might make the nice basis for any
web app that needs user management and plugins. Hmmm....
