Each of the 3 removed history addition requests follows a call to
ArticleView::showDefinition() with the same phrase/word as an argument.
Each showDefinition() overload adds its phrase/word argument to history.
These duplicate history additions weren't noticeable because
History::addItem() searches for and removes its argument from items to
avoid duplicate history entries. But the extra function calls, signal
emissions, linear searches and QList manipulation wasted processor time.
Preferences::sanitizeInputPhrase() transforms an input phrase by
removing its whitespace/punctuation prefix and suffix. Translating a
phrase from X11 primary selection or from clipboard, via mouse-over or
from the command line results in such sanitization. This is useful when
a punctuation mark or a space is selected accidentally alongside a word.
This sanitization can be undesirable, however, when an abbreviated word
is selected. For example: "etc.", "e.g.", "i.e.".
This commit implements searching for the input word with the punctuation
suffix preserved as an alternative form of the sanitized word to show
articles for both. For example, when the word "etc." is translated from
the clipboard, both "ETC" and "etc." articles are displayed.
The punctuation suffix is preserved when the word is passed from the
scan popup to the main window and when the translate line text is
refreshed (e.g. when the current group is changed). The suffix is not
stored in history and favorites (doing so would require file format
changes and possibly substantial code changes, this can be implemented
later if need be).
Trim the input phrase once in ArticleNetworkAccessManager::getResource()
instead of verbose trimming in multiple places in
ArticleMaker::makeDefinitionFor().
Closes #1350.
When a Wikipedia article is already cached, this change reduces the
amount of sent and received network data almost tenfold.
Setting up a network disk cache in the same way for dictNetMgr does not
noticeably impact the amount of network traffic. Either this network
access manager sends and receives very little data or the data is never
the same. So dictNetMgr does not need a disk cache.
Use QNetworkDiskCache's default maximum size of 50 MiB as the default
network cache size. This size is large enough to accommodate tens of
huge MediaWiki articles. It is also small enough that the user is
unlikely to run out of disk space because of the cache.
Clear network cache on exit by default because most users probably
don't load the same online articles after restarting GoldenDict. Plus
storing the network cache on disk indefinitely by default would be a new
and unexpected to the users privacy risk.
Nikita Moor came up with the idea and wrote an initial network disk
cache implementation in #1310.
Fixed by not adding dummy system tray under X env

KDE 5.14.5 (damn it's so ugly now)
GNOME (with topicons-plus extension)
This commit fixes #907, fixes #1097 and fixes #1155
abcabb77fa added a makeScanPopup() call
after applyQtStyleSheet() in MainWindow constructor to apply Qt style
sheets to the scan popup. This call destroys the scan popup created
earlier in the MainWindow constructor and creates a new instance.
Let us remove the first, now redundant invocation of makeScanPopup()
from MainWindow::makeDictionaries() to improve startup performance.
makeDictionaries() is currently called only once, so modifying it is not
a problem. If makeDictionaries() is used elsewhere in the future,
the added assertion will remind to reconstruct the scan popup.
For example, looking up "United States" in my local dictionaries, then
pressing Ctrl++ to increase zoom factor from 1 to 5 takes 4 seconds with
this change and 25 seconds without it. The same scaling takes 6 seconds
with this change and 45 seconds without when I enable English Wikipedia,
which has a particularly large "United States" article.
There is a workaround that speeds up zooming: look up a nonexistent
word, scale to the desired level, then go back to the large articles.
But this is tedious if large articles are open in scan popup or
in case of many tabs in the main window.
* #undef Bool with Qt4 as well as with Qt5.
* #undef min, #undef max from <X11/Xlibint.h>.
* #include <fixx11h.h> just after hotkeywrapper.hh. Unfortunately this
header can not be included in hotkeywrapper.hh directly because
some of the undef-ed words are actually used in hotkeywrapper.cc.
* #include <fixx11h.h> after <X11/Xlib.h> in mainwindow.cc just in case
hotkeywrapper.hh stops including this Xlib.h header in the future.
These changes should make future compilation errors less likely.
For example, without "#undef min" in hotkeywrapper.hh, including
<iomanip> in mainwindow.cc after the mainwindow.hh include resulted in
the following GCC 8 compilation error:
/usr/include/c++/8.2.1/bits/locale_facets_nonio.tcc:945:22:
error: expected unqualified-id before ‘(’ token
__minlen = std::min(__minlen,

* Run the freedesktop.org-specific code only on X11 (not on Mac).
* Use a (hopefully) unique destination .desktop file name to prevent
clashes with a goldendict.desktop file possibly created and customized
manually or by a system preferences tool.
* Allow different executable and .desktop file names because there is
no real dependency between them.
* Improve performance slightly with an early return.
Destroying and creating a scan popup instance twice in
MainWindow::editPreferences() is wasteful.
2b9dd55804 added the unconditional second
makeScanPopup() call below but didn't remove the existing call,
probably by mistake.
* add a new interface class AudioPlayerInterface;
* inherit a new proxy class Ffmpeg::AudioPlayer from it;
* partially switch ArlticleView to using the interface;
* expose MainWindow's AudioPlayerInterface instance to all ArticleView
instances;
* add a new AudioPlayerFactory class responsible for creating instances
of concrete classes derived from AudioPlayerInterface depending on
relevant Config::Preferences values;
* increase minimum supported Qt version from 4.5 to 4.6 in README
in order to use QScopedPointer introduced in Qt 4.6.
