Selva Nair 56ee704501 Use C standrad compliant printf specifications
%S --> %hs in wide format strings, %ls otherwise
%s --> %ls in wide format strings, unchanged otherwise
%c --> %lc in wide format strings

Resource files together have about 970 lines affected and
were edited by looping through all with
sed -i 's/%S/%hs/g' $file
sed -i 's/%s/%ls/g' $file
All other files were manually changed (about 85 lines).

Recent versions of mingw-w64 implicitly turns on __USE_MINGW_ANSI_STDIO
if _GNU_SOURCE, _XOPEN_SOURCE etc are defined (which we do usei).

This breaks non-standard spec such as %S. Anyway, we have been
gradually getting rid of those.

MSVC builds should not be affected.

v2: multiple occurrences in same line was missed in v1 (/g missing in
sed expression). Fixed.

Selva Nair 6b4e6d301a Delete old messages in the window when content grows beyond a limit 2021-06-25 20:48:02 -04:00
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.

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.

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.

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.
