Enable backtrace stuff only if GNU C library used, because current
backtrace implementation based on <execinfo.h> , which is not a
part of standard C library, it is a GNU extension.
This will be usefull when building with custom POSIX-compilant C
library (like musl) and no <execinfo.h> available.
Note: configure script will detect presence of <execinfo.h> and
enable/disable feature depending on it.
Feature is enabled by default.
Using iostream usually adds a lot of other operators (<<, endl), whereas
*printf takes only 1 function call.
Also use qUtf8Printable whenever possible.
We stored reference to parameters object in main(), but that object gets
deleted when we reset Application object upon entering daemon mode.
Change reference to copy to fix that.
write() is declared with __attribute__ ((__warn_unused_result__)) and as
such we shall check its return value. Took opportunity and adjusted
error reporting a bit: if writing to stderr fails, try to write to
stdout.
Arguments include adding torrents as paused/started, skiping hash check, setting category, downloading in sequential order, downloading first and last pieces first, and skipping the 'add new torrent' dialog. Added TriStateBoolOption class for specifying options that don't have a default value when unused (e.g. add-paused). Also improved command line usage text to include more information, have better organization, and not exceed 80 columns in width. Also also added firstLastPiecePriority field to BitTorrent::AddTorrentData, and modified TorrentHandle so that if first/last piece priority should be on, it will be toggled on after the torrent's metadata has loaded.
It may be useful to have different configurations either for portable
versions or for debugging purposes. To implement this we add two
options, avaliable via command line switches
1. An option to change configuration name ("--configuration"). The name
supplied via this option is appended to
QCoreApplication::applicationName() to form "qBittorrent_<conf_name>"
name for the configuration files.
2. An option to provide a path do directory where all the settings are
stored (kind of profile directory). There is a shortcut "--portable"
which means "use directory 'profile' near the executable location".
In order to implement that we have to perform initialisation of the
profile directories before the SettingStorage and Preferences singletones
are initialised. Thus, options parsing shall be performed without defaults
read from preferences.
Since Apple made difficult for users to set PATH and /usr/bin/python
is almost unusable, I simply add /usr/local/bin before default PATH
to pick up Homebrew Python.
On macOS 10.12 Sierra, Apple changed the behaviour of CFPreferencesSetValue()
truncating data after a null character. https://bugreports.qt.io/browse/QTBUG-56344
Due to this, we have to move from native plist to IniFormat.
Application process message and split it into params list itself (this
prevents code duplication).
Application store params unless other components ready to process them.
Application incapsulate all QMacApplication and SessionApplication logic
(this is too small to have separate classes).
Change project directory structure according to application structure.
Change 'nox' configuration option to something more meaningful 'nogui'.
Rename 'Icons' folder to 'icons' (similar to other folders).
Partially add 'nowebui' option support.
Remove QConf project file.
