This adds the libqb_http API, which is designed to support HTTP and
HTTPS usage from QB64-PE source.
The design consists of a single thread which services all the HTTP(s)
connections. There are then various libqb_http APIs exposed that allow
interacting with this thread to create a new connection, query
connection status, read data, or close the connection.
Internally the thread makes use of the curl_multi interface to allow a
single thread to service multiple HTTP(s) connections in parallel. This
means you can _OPENCLIENT() multiple HTTP connection in a row and all of
them will be serviced at the same time in whatever order data is
available.
HTTP is optional and selected via a Makefile setting. A stub is swapped
in if HTTP support is not used, which avoids need to add another build
flag to libqb.cpp.
We were incorrectly treating the empty string and NULL the same and
using a password dialog for both. It now has the correct behavior of
displaying the password when provided the empty string, but just
displaying a blank input box when provided NULL.
This applies various dialog settings so that the dialog is always on
top, and also so that Tab works as expected to move between the
controls. The Edit control is moved first so that it's focused when the
window appears.
Currently we have two different ways of determining what Window handle
to tie our dialogs too - we either use GetForegroundWindow(), or create
a completely new and hidden handle. The associated window determines
what process names shows up on notifications, and also which window
can't be interacted with while a dialog is open.
Both of those approaches aren't really good. In the case of
GetForegroundWindow(), it just returns whatever window the user has in
focus, which might be a completely different process. With the hidden
window, it means the dialog and notification aren't really tied to the
QB64-PE program, so you can still interact with the window even when a
dialog is open, and the notification doesn't show an exectuable name.
To solve this we're now using EnumWindows() to enumerate over all the
Windows on the system and find one associated with our ProcessId. We
then check if it's the top-level window and return it if it is.
If that process fails to find a window (such as if this is a
console-only program, or $SCREENHIDE is used) then we check if
GetConsoleWindow() gives us a handle and use that.
If neither approach works, then we fall back to creating a hidden window
so that the dialogs can still work.
A function was made unnecessary but wasn't removed, triggering a
warning. Additionally gcc likes parenthesis around `=` assignments used
for conditions.
Fairly simple, this sets the ES_PASSWORD flag when the default text is
blank.
Additionally I fixed the dialog callback to correctly call EndDialog()
rather than DestroyWindow().
These are the last of the quote checks, these don't require any
associated changes as the underlying Win32 functions already allow
quotes. They were simply added to keep parity with the functionality on
other platforms, that that has since been fixed.
This removes the VBS based InputBox for Windows and replaces it with a
version that uses DialogBoxIndirect to create the dialog. While it is a
bit more complicated in some respects, it removes any concerns about the
contents of the strings as they're no longer being inserted into the
generated script.
It also has the advantage that it doesn't spawn another process (which
then shows up in the task bar in some situations).
With this changes quote characters are allowed in all of the parameters.
Escaping the osascript commands requires two layers of escaping: One for the
script itself, and one for the sh arguments.
For the script itself, we simply have to escape the " character with \". When
then take the result of that and escape it sutably for sh arguments in single
quotes. We already have a function for that so we simply call that to do the
job.
