The opml parsing code handles cases where there are extra levels in the xml file
by copying the child to the main container. This corrupts the source instance
during the copy, which leads to corruption in the destination, and ultimately a
crash when it is later used.
To fix, do the copy in two steps, copying the child container to a temporary
location before copying to the destination.
The extends two functions:
- Recognize iPods as iPods, check for them in MakeDeviceUrls
- Give them a nice Icon in DeviceIcons (code taken from devicekitlister)
When there is album artist information available for a track, the user would
probably expect that "Repeat Album" should cycle through all songs with the same
album artist and album title, not only all songs with the same artist and album
title.
When the current playlist is changed, PlaylistContainer::SetViewModel is called
to set the new list. This calls PlaylistView::SetItemDelegates, which allocates
several objects that are never freed. Instead, move the call to SetItemDelegates
to PlaylistContainer::SetApplication, which is only called once.
Moving these from LibraryPlaylistItem removes local file specific
implementations of IsLocalLibraryItem and Reload. Returning true for
IsLocalLibraryItem caused ratings to be set on unrelated library songs.
Since the SimpleTreeItem constructor variant used from LoadAllDevices adds the
object to the parent's children list, use the parent's Delete method to destroy
it.
If the destination device has a transcode option set, then compute filenames
with updated extensions. This does not cover the case where Organise needs to
transcode due to format support.
QUrl interprets a single number as an ip address, so the track URL cdda://1
would become cdda://0.0.0.1. A previous fix addresses this issue by adding an
extra character "a" to the affected URLs then removing the last instance of the
character upon usage. However, this didn't apply when a path was present
(cdda:///dev/sr0/1), but would still attempt to reverse the change later
(cdd:///dev/sr0/1).
This change applies the fix-up to all cdda urls and moves the conversion
utilities to a single location.

In Application::MoveToNewThread, name the new thread after the object being
moved. Give those objects names as well.
The thread names display in gdb with "info threads".
Add a tab for Qt debug features. Initially provides access to dumpObjectTree() on
Application and MainWindow objects. This dumps the object's child objects to the
log.
The NetworkRemote is moved to a new thread after creation. On that thread, its
child classes create timers. When the network remote class is deleted on the
main thread, we see "Timers cannot be stopped from another thread".
To avoid this error, use deleteLater to delete NetworkRemote and its composition
classes on its own thread.
According to the gst_element_request_pad documentation, request pads must be
released after usage. They aren't automatically released and dereferenced when
the element is destroyed.
Add Accept, Apply, Reject methods to settings pages to mirror dialog. This will
allow settings pages to handle these events at a more granular level and will
allow common behavor in the base class.
Pressing the close button on the window sends a close event, where other methods
of exiting visualization just hide the window. If shown again after close, the
window will be empty. To fix this, handle and reject the close event. Call hide
instead.
The rowsAboutToBeRemoved signal from the model provides a parent index, but with
QStandardItemModel, top level items are added to an invisible root item that
doesn't have a valid index. This causes the range check to miss top level items
due to a perceived parent mismatch. When the load completes, it attempts to
access an object that has been deleted.
RedirectPolicyAttribute was introduced in Qt 5.9, but Debian Stretch is at 5.7.
This change can be reverted when the base support version moves to 5.9.
Add a class to wrap the URL in the playback engines. In the future, this will
contain authentication information for the specified URL. It can also include
the start and end time as well as other data that is currently specified along
with the URL.
While iterating over expandList in refreshExpanded, calls to setExpanded cause
the list to be appended. Since QList uses an array implementation that must
reallocate when reserved space is exhausted, iterators are unsafe for this case.
Use indexes, which are O(1) in QLists, instead of iterators.
- Group list and settings so they can be enabled/disabled together.
- Make default selection shortcut list. Previous behavior set options
for the first item, but didn't highlight selection.
- Rename ItemClicked to CurrentItemChanged to reflect correct signal.

Clementine detects a data directory in the same directory as the executable to
determine portable configuration. But there are some packages that create
/usr/bin/data, causing Clementine to run in portable mode.
Use a more unique data directory name, clementine-data, as the portable data
directory. For backwards compatibility, use the legacy data directory if the
already exists there.
Removal of items from a playlist is done with a single transaction. When
Queue::SourceLayoutChanged is called after this, the items in the queue are
checked one at a time. When an item is removed, it triggers dataChanged signal
from the model, connected to the SourceDataChanged slot. There, ItemCountChanged
is emitted which calls UpdateTotalLength. This method will assert when it finds
an item that is in the queue, but not in the playlist.
To solve this, disconnect the ItemCountChanged signal at the beginning of
SourceLayoutChanged and re-enable it after cleaning the queue. The method emits
the signal before returning.
The Google Drive Client::GetFile currently fails due to an extra / in the
request. Use QString::remove to strip all "/" characters from the id.
Note: While this fixes the ability to get the media URL, a change to the
Google Drive API breaks the playback. This will be addressed in a future
commit.
In some cases, URL queries contain auth information. For cases where error
strings are passed from other libraries, such as from gstreamer, add a utility
function, ScrubUrlQueries, to strip queries from URLs in strings.
Incorrect QJsonDocument::fromBinaryData was used several places in
DropboxService. Add a single ParseJsonReply method to the base class that
properly checks and parses network replies and reports errors.
- When parsing a response, use fromJson instead of fromBinaryData.
fromBinaryData expects a serialized binary format.
- Calling toString on a non-string JSON value will return an empty
string. Call toVariant().toString() to do the conversion.
- Add checks for network reply errors.
Noted previously, using the [] operator on a non-const QJsonObject causes the
creation of the key and does not work for checking existence. Convert the
remaining isUndefined call sites to use QJsonObect::contains.
There are several instances of the LibraryModel class used in the system. Each
of these creates a LibraryDirectoryModel instance, but only the instance held
by the main library is every used. Move this out of the LibraryModel class and
into the Library class.
At the time of this commit, the channel list from intergalactic.fm is
unavailable. To the user, this is failing silently. Add an error message for
this failure. If this issue persists, then the service should be removed or a
hardcoded station list should be used.
Use qLogCat to put verbose GStreamer callback messages into a new
GstEnginePipelineCallbacks category. Filter that category instead of
the entire class by default.
The fix-up for URLs for files that that begin with // no longer works since the
QUrl class determines that these modifications are invalid, resulting in an
empty string when converted. Instead of attempting to modify the QUrl, add a
utility function that makes the correction on the encoded byte array at time of
usage.
When a directory is removed from the library during a scan, the scan continues
until complete. This change cancels the scan immediately, unblocking the watcher
thread, then signals the watcher to remove the directory.
A second issue occurs when a previously scanned device is removed during a
scan. All remaining files will be marked as deleted. This change mitigates
this issue, but a timing hole still remains here.
This is can be done without protecting the directory reference since the method
that removes directories from the watch list is only called on the same thread
as the scan, and never during the life of the ScanTransaction object.
When scanning a device such as a mobile phone, it's likely that a directory
containing both image and audio files will be found. Besides the appearance of a
hung scan, it's unlikely that a relevant image will be found.
In the case where filters for relevant filenames don't yield results, set a
sanity limit on the number of images. If the list size is beyond than that
threshold, return an empty path.
On Linux systems, failure to watch a path may be caused by the limit set in
/proc/sys/fs/inotify/max_user_watches. This can be demonstrated by creating
a directory with a large number of empty subdirectories and adding that test
directory as a library.
Check that a file is readable before adding a watch. If adding the watch fails,
report the error to the user only once. Only add the path to subdir_mapping_
if watch succeeds.
QFileSystemWatcher::addPath returns a boolean to indicate success. Modify
QtFSListener::AddPath to reflect that. For now, the MacFSListener version will
always return true.
Using libmtp or libgphoto2 to access a device that gvfs has mounted causes the
connection to fail. libmtp is calling libusb_claim_interface which, according to
libusb documentation, will return LIBUSB_ERROR_BUSY if claimed by a different
program. For mtp and gphoto2 devices discovered by the GioLister, use the file
scheme and access the device through the gvfs mount.
The uri returned from g_file_get_uri is percent encoded. This causes the regex
in GioLister::MakeDeviceUrls to fail and causes the URL to be invalid. In this
case, it falls back to the file scheme. Newer versions of gvfs obtain the serial
id from udev instead of using the bus and device IDs.
Note that this bug covers a different issue where mtp is failing to connect. The
result is actually desired behavior. The follow-up change will address this.
A LibraryBackend may be deleted while an associated LibraryModel object is using
it. An example is an async query running while a connected device is removed.
To prevent this, use a share pointer for the LibraryBackend.
This fixes one case where LibraryBackend is used after deletion. However, the
raw pointer is still passed around in several other places. These should be
evaluated on a case-by-case basis to insure that circular depencencies aren't
introduced.
Create a thread pool for each LibraryModel object and block destruction until
all threads that are operating on this object are complete.
Note that this is not a complete solution. The async query also uses the library
backend which may still be deleted before the thread exits. This will be
addressed in a future change.
A commit in qt 5.7 changes a qWarning to a qFatal if a QThread is still running
when it's deleted. When we get the LoadFinished signal in MtpDevice, stop
the loader thread's event loop to avoid this situation.
See qtbase commit c8277b6e532
Add an "Advanced Settings" option to the gpodder sign in. If selected, a fully
qualified URL must be specified as the gpodder base. Upon successful login, the
URL is saved along with username and password. If advanced settings are not
selected, an empty URL is stored and the default will be used.
When QProxyStyle is given a base style, it take ownership of that object.
PlaylistView creates a proxy style based on its own style, but that is a shared
resource. When the PlayListView is destroyed, this object is destroyed.
Instead of passing style() to QStyle, pass nullptr. This will use the native
style.
It's not necessary for the PodcastSettingsPage class to have knowledge of
GPodderSync's login implementation. Handling the network reply in a single
location sightly simplifies the code. It also makes the handling order
more deterministic.
A sessionid cookie is stored when logging in to gpodder. After logging out, a
subsequent login with the same user name but incorrect password will succeed,
ignoring the authorization header. The incorrect password will be stored for
future use.
To fix this, reset the cookie jar for GPodderSync's network access manager at
logout.
A closure created by NewClosure that handles Qt signals is destroyed if the
signal object is destroyed, the slot object is destroyed, or the signal is
invoked. In the case where the sender is passed as a shared pointer, the
reference prevents the sender from being destroyed before the closure.
So for closures built to handle responses returned from ApiRequest in
GPodderSync, the closure object and the response object will only be destroyed
after the signal is invoked. In some cases, separate closures are built for
error signals as well. For these, only one closure will be destroyed. The other
closures and the response object will be leaked.
A simple fix for the success cases is to remove the unnecessary error case
closures and directly connect the signals to slots. This is low hanging fruit
and still leaves leaks in the error cases. Those cases will require a more
complete solution to properly manage the life cycle of the response object.
In most cases, timeouts can be applied to a reply after a request has been made.
But some APIs, such as libmygpo-qt, don't always provide access to the reply or
provide abort methods. For these cases, add an optional timeout to
NetworkAccessManager. If set, create a NetworkTimeouts instance in createRequest
and add the reply. Use the reply as the parent so that it is destroyed when the
reply is destroyed.
Apparently this was introduced in 2011 as a workaround to solve a problem in
libimobiledevice. However already in 2013 the problem was solved
in libimobiledevice:

Queue2 tends to hang up on pause, unable to start playing
again. Pipeline actually stays PLAYING with ASYNC state
change, so it becomes impossible to unpause the player
without stop or forward/backward seeks.
This reverts commit 2b280de663.
Instead of immediately saving, which leads to poor performance,
and possible hardware damage (see #6057), limit saves to once
per second (similar to how KDE does it). It also guarantees
that only one save is required per second, by sharing a QSettings
object, and establishes a signaling framework to put other
setting save events into (but only uses this for the two major
offenders: playlist tab switching and window resizing).
This is in contrast to 6a312e7, which simply deferred the save
until program exit, and caused problems for some people (see #6217
and #6209).

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.
