Selva Nair	e4fba0c003	Update echo-msg window from the thread that owns the window Change the way echo-msg window is update (thread safety). When new echo-msg content is available for display, update the window from the thread owning it by sending a message to it. A blocking SendMessage (with a timeout) is used, as the window needs access to the config's echo-msg buffer which is cleared on return from this this call.

Selva Nair	273322efb0	Add a From line at the top of new echo messages This adds context to the message in the form: "From: config-name date/time text" displayed as right-aligned and in italics. Also remove the show argument to AddMessageBoxText() and move ShowWindow() to the caller. Signed-off-by: Selva Nair <selva.nair@gmail.com>	4 years ago
Selva Nair	ba05ea0de9	Detect urls in echo message make them clickable - Left clickng on http or https url will open it on the default browser Several other URL schemes are detected and formatted as clickable links, but we only support opening of http/https links. Note on spaces in URLs: We unescape all %xx occurrences in the echo message text so that %20 will be converted to space in plain text. This means embedded spaces in URLs will not work even if written as %20. An option is to use %2520 which will get conveted to %20 after the unescaping. A better option is to enclose the URL in <>. If the text inside <> starts with a valid scheme (http, https etc.), the entire text including spaces is parsed as the URL. Signed-off-by: Selva Nair <selva.nair@gmail.com>	4 years ago
Selva Nair	482bf586df	Persist echo msg history in registry - Echo msg history saved to registry on disconnect and loaded on reconnect. - Muting of repeated messages now work across GUI restarts. Signed-off-by: Selva Nair <selva.nair@gmail.com>	4 years ago
Selva Nair	82e17b239e	Mute echo message if repeated or disabled - Suppress messages with exactly same content as previously displayed within popup_mute_interval (24h by default). This parameter may be set on command line as "--popup_mute_interval n" where n is in hours. - Command line option '--disable_popup_messages' disables all echo message popups (window and notification). This patch only handles suppression of repeated messages during reconnections. TODO: Persist message history in the registry and use it to mute repeated messages after disconnects and across restarts of the GUI. Signed-off-by: Selva Nair <selva.nair@gmail.com>	4 years ago

Selva Nair	00732e1d9e	Parse and display messages received by echo msg commands Process four new echo commands to construct messages to be displayed to the user: echo msg message-text echo msg-n message-text echo msg-window message-title echo msg-notify message-title Note: All rules of push and echo processing apply and determine what is received as echo commands by the GUI. In addition, 'url-encoded' characters (% followed by two hex digits) are decoded and displayed. The message is constructed in the GUI by concatenating the text specified in one or more "echo msg text" or "echo msg-n text" commands. In case of "echo msg text" text is appended with a new line. An empty text in this case will just add a new line. The message ends and gets displayed when one of the following are receieved: echo msg-window title echo msg-notify title where "title" becomes the title of the message window. In case of msg-window, a modeless window shows the message, in the latter case a notification balloon is shown. Example: when pushed from the server: push "echo msg I say let the world go to hell%2C" push "echo msg I must have my cup of tea." push "echo msg-window Notes from the underground" will display a modeless window with title "Notes from the underground" and a two line body -- I say let the world go to hell, I must have my cup of tea. -- Note that the message itself is not quoted in the above examples and so it relies on the server's option-parser combining individual words into a space separated string. Number of words on a line is limited by the maximum number of parameters allowed in openvpn commands (16). This limitation may be avoided by quoting the text that follows so that the option parser sees it as one parameter. The comma character is not allowed in pushed strings, so it has to be sent encoded as %2C as shown above. Such encoding of arbitrary bytes is suppored. For example, newlines may be embedded as %0A, though discouraged. Instead use multiple "echo msg" commands to separate lines by new line. An example with embedded spaces and multiple lines concatenated without a new line in between (note use of single quotes): push "echo msg-n I swear to you gentlemen%2C that to be" push "echo msg-n ' overly conscious is a sickness%2C ' " push "echo msg-n a real%2C thorough sickness." push "echo msg-notify Quote of the Day" will show up as a notification that displays for an OS-dependent interval as: -- Quote of the Day I swear to you gentlemen, that to be overly conscious is a sickness, a real, thorough sickness. -- where the location of the line break is automatically determined by the notification API and is OS version-dependent. Commands like "echo msg ..." in the config file are also processed the same way. It gets displayed when the GUI connects to the management interface and receives all pending echo. Pushed message(s) get displayed when the client daemon processes push-reply and passes on echo directives to the GUI. TODO: The actual window that displays the messages is implemented in the next commit. Signed-off-by: Selva Nair <selva.nair@gmail.com>	4 years ago
