Previously, the number of processes spawned was always
QThread::idealThreadCount() (returning the number of logical CPU
cores). On new systems with many cores, however, this can result
in 12, 16, 24, or ... processes being spawned, which is a bit
excessive.
This establishes a new config variable,
'max_numprocs_tagclients' within the Settings group, in order
to limit the maximum number of tag client processes that get
spawned. It also adds a means of setting this via the Behavior
page in Settings. It can be set to any integer in the interval
[1, QThread::idealThreadCount()]; it defaults to the maximal value
so as to emulate the old behavior.
"Clementine" (as returned by QCoreApplication::applicationName())
does not match the system .desktop file name (but it may match user
.desktop files, as was the case for me); Clementine won't be picked up
as an application in KDE Plasma notification settings unless it case
matches.
Qt 5.11 added a function allowing the first column in a list to be set
to be movable. Contingent on its availability, make the first column
of the playlist viewer draggable.
In 2011, there was a bug that caused NVIDIA drivers to hang
Clementine on shutdown. In 2012, only some drivers had the
fix for this issue. Now, in 2019, we do not need to work
around this bug. By reverting commit
c2723008a2
we work around known bad drivers, but do not penalize all
NVIDIA users for this ancient bug.
Async song loading can fail without user feedback. This change adds return codes
to these async load functions. It will now produce an error dialog in simple
scenarios (test case is user selecting a file that is not readable). Other cases,
such as directories and playlists, aren't yet covered.
QTimeLine duration must be greater than 0. If set to 0, a default of 1000ms will
be used. To avoid this, enforce a minimum of 1ms for pause and cross fade values
if those fades are enabled.
There are a number of cases where gst_pipeline_get_bus,
gst_element_get_static_pad, and g_object_get are called without releasing
references. In addition to memory usage, some of these elements hold file
descriptors. In normal operation, two file descriptors are leaked for each
played track. The default fd ulimit for many linux distros is 1024. This
is likely the cause of the crash reported in issue 6309.
This change fixes the obvious and consistent leaks, but it's probably not a
complete solution. There are many error and corner conditions that need to be
examined.
In the case that an error occurs in ReplaceDecodeBin before the bin is added to
the pipeline, unreference the object to allow cleanup. This change also separates
CreateDecodeBinFromUrl from ReplaceDecodeBin, following the pattern of
CreateDecodeBinFromString.
If ReplaceDecodeBin fails from TransitionToNext, uridecodebin_ will not be
replaced with a new element. Since TransitionToNext does not check the return
value, it unknowingly deletes uridecodebin_.
As reported in issue 6302, playing a stream that causes gstreamer to error at
start can cause a crash. The problem occurs when the MoodbarPipeline receives a
pad-added signal after it has handled an error callback. In the error callback,
the builder_ is freed. In the pad-added handler (NewPadCallback), this object
is accessed.
This change adds a running_ flag that is set when the pipeline is started and
cleared on an error, end of stream, or object destruction. We check this flag at
the beginning of NewPadCallback. For sanity sake, we also check the builder_
pointer before dereferencing. Note that checking the state of the pipeline
wasn't an option since the pipeline is in the process of changing states during
the pad-added callback and gst_element_get_state wants to block during a state
change.
This solution is not complete as there are still some syncronization issues.
With this specific situation, the error and new pad callbacks appear to always
occur on the same thread, but that's probably not true for all error conditions.
The object is also destroyed by a different thread, so it may be possible that a
callback can occur at the wrong time during or after the deletion of the object.
See https://github.com/clementine-player/Clementine/issues/6302
There is a small chance that a device lister is able to discover and add a
previously known device before it is added by the database loader thread.
In this case, copy the data that is user-settable to the existing DeviceInfo
object and destroy the object created from the database query.
This adds and utilizes a new FindEquivalentDevice method that compares the
device unique IDs. This could probably be made more robust as the unique
IDs for some listers may change. However, this is a problem with the database
storage implementation in general.
When DeviceManager initializes, it creates a thread to load device information
from the database. Part of this process includes use of QPixMap for icons which
produced a warning message:
22:32:53.763 WARN unknown QPixmap: It is not safe to use pixmaps outside the GUI thread
In addition, the device is added to the view using beginInsertRows and
endInsertRows. This could contend with a device added by a lister signaling
PhysicalDeviceAdded.
To solve these problems, this change moves the icon loading and insertion to the
main thread. LoadAllDevices reads the data from the database and creates the
DeviceInfo object, then sends a signal to the main thread. In the signal
handler, the icon is loaded and the device is added to the master list and view.
When unmounting a device, the ConnectedDevice object is destroyed. The
FileSystemDevice destructor waits on its worker thread. If a scan is in
progress, this will block until completion.
There is an existing Stop method in the LibraryWatcher class that is intended to
stop long running operations. To fix, or at least significantly shorten this
hang, we'll call this before waiting for the thread to exit. Also add a
stop_requested check in the cover art scan.
In addition, add a call to Stop in the Library destructor, which has a similar
usage.
Currently, the failure to connect to an MTP device results in the UI displaying
an open device that appears empty. This change introduces a method
ConnectedDevice::ConnectAsync() that is expected to handle any connecting tasks
that could block asynchronously. Upon completion, this emits a ConnectFinished
signal that indicates success or failure. The row in the UI is only updated
after the successful response is received. Upon failure, DeviceManager will
clean up and the row in UI is left in the pre-connect state.
Currently, only the MtpDevice utilizes this mechanism. All other devices use a
default implementation that immediately reports success.
In 1.37.2, gvfs switched to URIs that remain consistent across USB device
re-enumerations. This removed the usb bus and device numbers from the URI. In
the case that these values aren't found in the URI, try to parse Unix device
name property and pass results as query params on the URL. Pay attention to
these params in MtpConnection.
See gvfs commits 3a7bb06b and efc76d0c for reference.
* Qt5::Test is not required in the global QT_LIBRARIES definition
* Qt5::DBus had already been optional, drop bogus pkgconfig search
This partially reverts commit 4321ecf7d2.
* Find X11 only once, in root CMakeLists.txt
Since we have HAVE_X11, use HAVE_X11 in cmake.
GError messages contain non-ascii characters. This normally just produces some garbage when we use the default QString contructor that assumes ASCII for logging. However, when a message includes the right double quote, UTF-8 sequence 0xE2 0x80 0x9D, the final byte is OSC. VT100 expects a command sequence to follow and stops echoing output until it sees ST or BEL character, which may never come. Thus, the console output is halted.
This change uses QString::fromLocal8Bit instead of depending on the default constructor. About half of the sites in the codebase had already been converted.
One side effect is that log messages are quoted. There are additional options to control this, but those were only introduced in Qt 5.4.
GPodLoader and MtpLoader Error signals were connected to Error signals in their repective device classes, but the actual signal definition in ConnectedDevice was removed in a refactor several years ago. This change adds LoaderError slots to these device classes and reports the error in the manner of the refactored code.
* Display podcast episode information.
Add an EpisodeInfoWidget with title, author, duration, date, and description fields. Include this in the PodcastInfoDialog. If exactly one episode is selected, then show both the podcast and episode widgets and display the episode's URL. Otherwise, hide the episode widget and follow the existing behavior. Note that the desription field for the EpisodeInfoWidget uses the QLabel and does not currently download embedded images.
Add an always_show_hours option to the PrettyTime methods to include hours in formatting even if the field is zero. This is less ambiguious in some cases where duration is displayed.
* Apply patch from automated formatter test.
* Allow ignoring prefixes when sorting playlist
This introduces new configuration options which allow you to ignore
prefixes while sorting the playlist on album, artist and titles.
Prefixes are configurable, default are "a" and "the".
* Change QStringLiteral to QString for compatbility with Qt 4.8
This introduces new configuration options which allow you to ignore
prefixes while sorting the playlist on album, artist and titles.
Prefixes are configurable, default are "a" and "the".
- Disabling playlist row glow by default
- Track slider popup visible by default, add hide()
to ensure not visible by default (no more repaints)
- Set kTrackSliderUpdateTimeMs to 500. IMO 40 is too low
This should partially fix issue #1079
When switching between tracks with different sample rates, the probe queue blocks before the pipeline can emit EOS.
This prevents the track change from proceeding without manual intervention. This appears to be because the queue
element doesn't handle the rate change correctly (either due to buffer length, or cap negotiation).
The queue2 element however does handle this without blocking indefinitely.
Current VGM format implementation in GStreamer (gstgme) only supports Sega Geneses (Mega Drive) and Sega Master System emulation.
GStreamer also cannot handle the VGZ format (a shorthand for vgm.gz, a gzipped archive that contains a song) which means
that users will currently have to extract the contents of their VGZ files to individual vgm files.
Let's the user see the error message what failed instead of Clementine crashing.
Also don't do gst_object_unref unless bin is set.
This fixes GStreamer-CRITICAL gst_object_unref: assertion 'object != NULL' failed
* Add option to verify subsonic server certificate.
Defaults to true, as it is safer to have a server certificate verified,
even more so, if the server is used over an insecure WAN link.
During subsonic configuration the checkbox can be deactivated, so that
no certificate verification will occur when talking to a subsonic
server, allowing for self-signed certificates.
With the proliferation of let's encrypt certificates there's probably
less need for this option but it has been requested and hard-coding
verify-off is IMHO bad security practice.
If a valid certificate has been installed, the configuration file can be
modified manually and after a restart Clementine will perform a proper
server certificate verification.
The patch might need some UI polishing and asks for string translations
but is operational so far.
* Satisfy CLang format checker.
* Use QSettings' default value support.
* Consistently use QSettings' default value method.
Qt's QUrl parser does no longer accept pure numeric hostnames without
trying to make a dotted IPv4 address of them.
Thus current method of storing subsonic's numeric ids in the host part
of a QUrl ("subsonic://<id>") does no longer work.
Instead a query is constructed omitting the host-part entirely and using
"subsonic://?id=<id>" to store and retrieve subsonic titles.
`column_widths_` is managed elsewhere. Resetting it on model change
makes tab-switching slow, and---if a vertical scroll bar becomes visible
or hidden---can be triggered in unexpected situations, leading to
visible column information loss.

Any access, read or write, via QSettings requires locking
`Clementine.conf`. On some devices, this can be slow. Moreover, it also
increases power use and wear on devices such as SSDs.
To improve the situation, defer QSettings updates until program close
for window resize, current playlist tab, and playlist geometry, i.e.
`PlaylistView::SaveGeometry`.
Also, limit `PlaylistView::LoadGeometry` to once per program run.

There's no difference between close() and hide() if WA_DeleteOnClose is not set, so if we're going to hide the window we might as well accept the event.
Ignoring the event may interrupt shutdowns since it signals that the application doesn't want to close the window, at least this happens on Plasma 5.11 when Clementine is not minimized to tray.
The previous fix introduces a regression on some platforms
which did not generate a leaveEvent with the TrackSliderPopup
was displayed. Logic is introduced to identify bonafide mouse
motion out of the TrackSliderSlider.
There was an issue where the song items were only being shown
from a fresh start up but not when the playlist was created. This fixes
that issue and refactors the AddPlaylist code
This allows power users who keep 100s of playlists to easily
find a playlist either by directory name, playlist name or by
searching for a song artist/title a playlist might contain
* Replace Nokia sidebar widget with QTabWidget
The old sidebar widget was written by Nokia 10 years ago
and was a hand made hardcoded mess of widgets trying to
emulate a QTabWidget.
This commit completely replaces it with a widget of the
same name (FancyTabWidget) but is a much simpler subclass
of the standard QTabWidget allowing for a 50% code reduction.
There is still some manual draw code copied over to get the
exact same look of the previous widget but this is not strictly
necessary and can be later refactored with simpler drawControl
code based on styling preferences.
Benefits:
- 50% code reduction
- Easier to understand standard QTabWidget mechanics
- Built-in support for re-arranging and closing tabs
* Save and restore sidebar tab order
Allow the user to rearrange the tab order by dragging
tabs to a new location. Tab order is saved on exit and restored
on start
* Fix some code formatting issues
When the playlist doubleclick behavior is set to add songs to the queue,
the playback of the queue also starts if no song is currently
playing. To play the queue from the current playlist, we must set the
active playlist to the current one before starting the playback.
Fixes#5714.
When the network connection changes while playing an HTTP stream, I always get the "Server does not support seeking." error from GStreamer.
It seems like GStreamer tries to seek on reconnect, which fails, an propagates the error to Clementine which in turn ceases playback with
the error message handed through from GStreamer, even though there is now a perfectly fine network connection again.
As a workaround, try to reload the stream when this error occurs.
