Windows wakes up from sleep #8806

After installing the latest version of Bitcoin Core, the computer won't stay in sleep mode for more that a minute or so. It goes to sleep just fine but it is woken up by bitcoin-qt.exe soon afterwards. I believe the issue is reproducible with any modern Windows OS.

Steps to reproduce below:
1. Install BitCoin Core 0.13.0 x64
2. Wait for it to sync with network and have active connections.
3. Hide BitCoin Core to tray.
4. Put the computer to sleep.
Expected behavior

Computer stays in sleep

Actual behavior

Computer is awoken soon afterwards with following event: bitcoin.zip

What binary version was used (official or self compiled)

0.13.0 x64 official

Machine specs: CPU, RAM, Disk space & OS (Windows, OS X, Linux)

Windows 8.1 Pro x64

No idea why it would point at bitcoin-qt.exe as wake-source, there is no code to wake on activity or take a wake-lock or such.

If I turn Bitcoin off, the sleep starts to work. IIRC there used to be similar bug in Boost libraries where simple sleep (or was it wait_for()) was able to wake up the PC.

Edit: As I look at source code, it might be the exactly same issue as I noticed reference to Boost 1.59.0. It's already fixed in 1.60.0 - see https://svn.boost.org/trac/boost/ticket/11368.

Ok, yes, currently building using 1.59, we should probably bump boost to 1.61 for 0.14

Now that depends Boost has been bumped in master, is this enough of an issue that it needs back-porting for 0.13.1 ?

I certainly wouldn't mind. It's quite annoying bug if one turns off his computer at night.

@fanquake in that case the specific change should be backported in boost and tested, I think it's a bad idea to just do a blanket update of boost on a backport release.

I can't replicate this. It may be be due to the Wi-Fi on my laptop shutting off on sleep. Or it could be that I am not synced yet.

Edit: Was able to replicate on my desktop.

I am assuming this is fixed after #8899?

Yes, this is fixed now.
