The original broken code was intended to stop using ifstream
and ofstream to open files, but it used a very old MSVCism to
open streams from FILE*.
In the case for reading, this patch replaces that code by using
standard c file manipulation to read the data into a stringstream,
and then it uses the existing stream-based code to read from there.
Similarly the ofstream in the code for writing the recent files list
is replaced by a stringstream, and then a c-string is extracted
from it and written using standard c file manipulation.
Also tweaked a couple of typos from rgareus :)
During session-load, ardour calls Route::SoloControllable::set_value()
which calls Session::set_solo() which in turn sends a session-rt event.
Along with other rt-events (locations,..) the current solo logic limits
Ardour to only load sessions with about >= 200 tracks.
now bumped to a few thousand tracks.. until a proper solution comes along.
Use gdk_pango_layout() for all text-size calculations.
In Canvas::Text always use the same context (local image surface)
for layouting (prior to this, local and window-context mix resulted in
different sizes).
This change should ensure that our "been_here_before" file ('.a3' or whatever) will get created successfully - even for user paths with non-English characters in them.
If this experiment works on all platforms, there are several other areas where we'll probably need something similar.
On linux SndFileSource::get_soundfile_info was being called with an empty path
value when clicking on a folder in the left side part of the file browser which
resulted in an unnecessary error message.
On Windows every time a directory was selected in the Import dialog,
SndFileSource::get_soundfile_info would fail to open the directory in read only
mode and produce an error, but as we don't want to query/open soundfile info
for directories anyway just test and return if the path is a directory.
