1) for parameters use references to CString instead of pointers to
buffers;
2) when returning strings use CString instead of pointer to char buffer
which caller needs to deallocate;
3) use BString even more.
1) replaced characters arrays with class BString through the whole
program. The string formatting code has become much cleaner.
2) class Util returns error message via CString instead of character
buffers.
3) few more places to use CString.
Built-in web-server doesn’t print warnings to log for certain files
which are or can be missing but that’s OK for them:
- package-info.json - update information file, which is available only
with binary packages supporting automatic updates;
- favicon.ico - the file is located in img-subdirectory; web-clients
requesting the file from the root directory are doing this wrong;
- apple-touch-icon*.png - iOS safari asks for these files, but we don’t
have nice icons.
Implemented authorization via X-Auth-Token to overcome Safari’s bug,
where it may stop sending HTTP Basic Auth header when executing ajax
requests leading to communication errors in web-interface. With
X-Auth-Token only the first request must include HTTP Basic Auth, for
sub-sequential requests the web-interface sends X-Auth-Token, received
from server on first request. The web-interface even tries to remove
the HTTP Basic Auth header from request to improve security; this
however works only in Chrome, other tested browsers still send the Auth
data anyway (IE, Safari, Firefox).
