Remove CO* constructor to COT. Cleanups. by daschuer · Pull Request #16 · mixxxdj/mixxx

daschuer · 2013-06-19T22:42:12Z

This is a refactoring, needed before we can continue to introduce additional CO changes.
I would like to merge this at first because it is already quite big and has no critical changes (I hope)

In addition of some renaming the main part of this patch is that I have decoupled CO from COT. Now it is not required to have a CO to instantiate a COT or COTM or COTW.

For the next steps, I will try to get rid of the two CO hash storages. I will replace this with a CO cache using smart pointers. Then I will try to get rid of the places where a CO and a COTM is instantiated for the same Key.
I will make CO to a Owner/Master/Creator CO and COT to a Slave/Consumer CO. I hope I can also eleminate COTM. Based on this new structure we can than introduce Int and String CO and do other nice things.

This indentation (8-space indent) doesn't match the rest of Mixxx -- please use 4-space indents.

Please! .. let us (slowly) change this to 8-space indent for line wrap!

The code is much more easy to read. Since we have the braces at the and of the line, you can instantly distinguish between a line wrap and a conditional code block. See "src/control/control.cpp @@ -49,7 +49,7 @@" below.

Here what other think:

it is the default K&R Style of Eclipse to wrap lines with 2 x indentation.

It is part of http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml#Function_Calls
** They wrap at the function parentheses or at 2 x default indention (2) -> 2 x 2 = 4

The function parentheses wrap is part of th Mixxx style guide as well, but it is not suitable in any cases, eg. when the function parentheses is already near the line end like in the sample above.

The same for line wrap in Function declarations http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml#Function_Declarations_and_Definitions

You're right, it's the right style (if Google style had 4-spaces as default indentation) -- sorry about that.

here you can see th advantage of double indentation line wrap.

Yea, this has annoyed me for a long time too but for consistency with the rest of the code I was sticking to 4-space indent.

I hope the branch is now in a merge-able state, even though i was no able to test my latest changes.

Thank you for the changes -- everything looks good except the valueChangedFromEngine() changes. You've added the signal back in but didn't add back in all the connections. Please revert the removal of the connections.

Looks good to me -- thanks.

…h sync When loading a track that is not yet present in the library (and thus doesn't have any BPM because it hasn't been analyzed yet) while another deck is playing and both decks have sync enabled, a debug assertion is triggered: DEBUG ASSERT: "isValid()" in function double mixxx::Bpm::value() const at src/track/bpm.h:53 Aborted (core dumped) The backtrace looks as follows: #0 0x00007f175c87234c in __pthread_kill_implementation () at /usr/lib/libc.so.6 #1 0x00007f175c8254b8 in raise () at /usr/lib/libc.so.6 #2 0x00007f175c80f534 in abort () at /usr/lib/libc.so.6 #3 0x00007f175cf05ee4 in qt_assert(char const*, char const*, int) () at /usr/lib/libQt5Core.so.5 #4 0x000055deb2e67e1c in mixxx::(anonymous namespace)::handleMessage(QtMsgType, QMessageLogContext const&, QString const&) (type=<optimized out>, context=<optimized out>, input=<optimized out>) at src/util/logging.cpp:355 #5 0x00007f175cf47128 in () at /usr/lib/libQt5Core.so.5 #6 0x00007f175cf3fd8a in () at /usr/lib/libQt5Core.so.5 #7 0x00007f175cf06526 in QMessageLogger::critical(char const*, ...) const () at /usr/lib/libQt5Core.so.5 #8 0x000055deb2e5c720 in mixxx_debug_assert(char const*, char const*, int, char const*) (assertion=assertion@entry=0x55deb39bd0db "isValid()", file=file@entry=0x55deb39bbf30 "src/track/bpm.h", line=line@entry=53, function=function@entry=0x55deb39bbf08 "double mixxx::Bpm::value() const") at gsrc/util/assert.h:9 #9 0x000055deb2ee7e7e in mixxx_debug_assert_return_true(char const*, char const*, int, char const*) (function=0x55deb39bbf08 "double mixxx::Bpm::value() const", line=53, file=0x55deb39bbf30 "src/track/bpm.h", assertion=0x55deb39bd0db "isValid()") at gsrc/util/assert.h:18 #10 mixxx::Bpm::value() const (this=<synthetic pointer>) at src/track/bpm.h:53 #11 mixxx::operator*(mixxx::Bpm, double) (multiple=1, bpm=...) at src/track/bpm.h:160 #12 SyncControl::setLocalBpm(mixxx::Bpm) (this=<optimized out>, localBpm=...) at src/engine/sync/synccontrol.cpp:567 #13 0x000055deb34c7ba3 in EngineBuffer::postProcess(int) (this=0x55deb56eb060, iBufferSize=2048) at src/engine/enginebuffer.cpp:1318 #14 0x000055deb3139023 in EngineMaster::processChannels(int) (this=0x55deb5449440, iBufferSize=<optimized out>) at src/engine/enginemaster.cpp:383 #15 0x000055deb31394f7 in EngineMaster::process(int) (this=0x55deb5449440, iBufferSize=iBufferSize@entry=2048) at src/engine/enginemaster.cpp:410 #16 0x000055deb2f91d0b in SoundManager::onDeviceOutputCallback(long) (this=<optimized out>, iFramesPerBuffer=iFramesPerBuffer@entry=1024) at src/soundio/soundmanager.cpp:596 #17 0x000055deb32dd794 in SoundDevicePortAudio::callbackProcessClkRef(long, float*, float const*, PaStreamCallbackTimeInfo const*, unsigned long) (this=0x55deb553e6b0, framesPerBuffer=1024, out=<optimized out>, in=<optimized out>, timeInfo=<optimized out>, statusFlags=<optimized out>) at src/soundio/sounddeviceportaudio.cpp:965 This happens because `newLocalBpm` is invalid when `localBpm` is invalid. Trying to do sync decks while no tempo information is available does not make sense, so we only synchronize decks if the local BPM is available.
