<h1>15 May 2013 Upgrade Deadline</h1>
|
|
<h2>What is happening</h2>
|
|
<p>
|
|
If you are using Bitcoin-Qt/bitcoind version 0.7.2 or earlier, you must take action
|
|
before 15 May, 2013. If you do nothing, you are likely to be left behind and
|
|
will be out of sync with the rest of the Bitcoin network.
|
|
</p>
|
|
<p>
|
|
We recommend that you
|
|
<a href="https://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.1/">upgrade to version 0.8.1</a>
|
|
before the 15th of May to avoid any issues. If you are a solo miner or mining pool operator,
|
|
please see the the notes at the end of this page for how to upgrade safely.
|
|
</p>
|
|
<h2>If you cannot upgrade to version 0.8.1</h2>
|
|
<p>
|
|
If you cannot upgrade to the latest version, you can still avoid the problem.
|
|
Create a file called DB_CONFIG in the bitcoin data directory, containing
|
|
these two lines:
|
|
</p>
|
|
<blockquote>
|
|
<pre>
|
|
set_lg_dir database
|
|
set_lk_max_locks 120000
|
|
</pre>
|
|
</blockquote>
|
|
<p>
|
|
<a href="https://en.bitcoin.it/wiki/Data_directory">Look here</a> if you need help
|
|
finding the bitcoin data directory.
|
|
</p>
|
|
<h2>Miners/mining pool operators</h2>
|
|
<p>
|
|
If you are creating new blocks (you are a solo miner or mining pool operator), then
|
|
you should be aware that upgrading from 0.7 to 0.8 requires a lengthy
|
|
re-indexing operation; you <b>must</b> wait for the reindex to complete before
|
|
serving work to miners.
|
|
</p>
|
|
<p>
|
|
And if you are creating blocks and cannot upgrade to version 0.8.1 for some
|
|
reason, you should <b>not</b> set_lk_max_locks in a DB_CONFIG file until
|
|
May 15th; if you increase locks before then you run the risk of creating
|
|
or building on blocks incompatible with the rest of the network.
|
|
</p>
|
|
<h2>Why this is necessary</h2>
|
|
<p>
|
|
A bug caused a <a href="chainfork.html">temporary block chain fork on 11 March, 2013</a>.
|
|
After investigating
|
|
that bug, we determined that the bug can happen even if the entire network was
|
|
still running old versions of Bitcoin-Qt/bitcoind. Therefore, the only option is to
|
|
require everybody to either upgrade or workaround the bug.
