Merge lp:~nwilliams/akiban-persistit/release-script into lp:akiban-persistit

[Nathan Williams]

Add script for building release packages, minor doc tweaks, first pass 3.1.2 release notes.

Nothing terribly interesting. The script will take a release branch (created elsewhere, already present in existing release process) and build all release artifacts: open and community edition zip/tars with signing and docs for the website.

There was a bit added to the Sphinx config and tweaks to GettingStarted to consolidate some of the repetition in version numbers. These were factored out into common substitutions defined in the config so we only have to change one place. Minor rewording to use these new defines and links add as well.

Also take a first pass at the release notes for 3.1.2. Basically just describing fixed bugs. This could definitely use some review. Additionally, reorganize the release notes to better handle multiple entries: common section for building, etc and then date/summary/issues for each release.

[Peter Beaman (pbeaman)]

Looks great.

+************************************
+
+Release Date
+============
+June 15, 2012
+
+Overview
+========
+This is a bug fix release of the Persistit project (https://launchpad.net/akiban-persistit).  
+
+Fixed Issues
+============
+
+Infinite Loop When Repacking Buffer
+-----------------------------------
+
+https://bugs.launchpad.net/bugs/1005206
+
+This was introduced late into the 3.1.1 development cycle. This could occur if a buffer required restructuring during pruning of a long value that was previously stored under a transaction. Upon the next save of this buffer to disk (e.g. shutdown), an infinite loop would occur.
+
+Corruption Exceptions During Various Operations
+-----------------------------------------------
+
+https://bugs.launchpad.net/bugs/1010079
+
+.. note::
+   Only the message indicates a database corruption. The data volume is actually correct and intact.
+
+This was introduced late into the 3.1.1 development cycle. This could occur if pruning a buffer containing a long record previously stored under a transaction required removal of keys and then that buffer was reused without further modification. A parallel structure associated with the every ``Buffer``, the ``FastIndex``, was not maintained during this operation.
+
+Slow Accumulator Operations
+---------------------------
+
+https://bugs.launchpad.net/bugs/1012859
+
+This bug preexisted, but was unknown to, the 3.1.1 release. If a thread starting a new transaction was interrupted during the call to ``begin()``, there was a chance for an internal object to wind up in an invalid state. This invalid state caused no visible consequences other than slower than expected ``Accumulator`` actions if this had occurred many times.
+
+Known Issues
+============
+As described in the *3.1.1 Known Issues*.

@@ -49,37 +110,36 @@
 
 All operations within Trees such as store, fetch, remove and traverse are correctly supported within transactions. However, the operations to create and delete Tree instances currently do not respect transaction boundaries. For example, if a transaction creates a new Tree, it is immediately visible within other Transactions and will continue to exist even if the original transaction aborts.  (However, records inserted or modified by the original transaction will not be visible until the transaction commits.) Prior to creating/removing trees, transaction processing should be quiesced and allowed to complete.
 
-Problems with Disk Full - Bug 916071
+Problems with Disk Full
 ------------------------------------
 
+https://bugs.launchpad.net/akiban-persistit/+bug/916071
+
 There are rare cases where Persistit will generate exceptions other than java.io.IOException: No space left on device when a disk volume containing the journal or volume file fills up. The database will be intact upon recovery, but the application may receive unexpected exceptions.
 
-Out of Memory Error, Direct Memory Buffer - Bug 985117
+Out of Memory Error, Direct Memory Buffer
 ------------------------------------------------------
 
+https://bugs.launchpad.net/akiban-persistit/+bug/985117
+
 Out of Memory Error, Direct Memory Buffer.  Can cause failed transactions under extreme load conditions as a result of threads getting backed up writing to the journal file. However, this error is transient and recoverable by by retrying the failed transaction.
 
 * Workaround: Ensure your application has the ability to retry failed transactions

-Tree#getChangeCount may return inaccurate result - Bug 986465
+Tree#getChangeCount may return inaccurate result
 -------------------------------------------------------------
 
+https://bugs.launchpad.net/akiban-persistit/+bug/986465
+
 The getChangeCount method may return inaccurate results as its not currently transactional.  The primary consumer is the PersistitMap. As a result of this bug Persistit may not generate java.util.ConcurrentModiciationException when it is supposed to.
 
-Multi-Version-Values sometimes not fully pruned - Bug 1000331
+Multi-Version-Values sometimes not fully pruned
 -------------------------------------------------------------
 
+https://bugs.launchpad.net/akiban-persistit/+bug/1000331
+
 Multi-version values are not always pruned properly causing volume growth.  The number of MVV records and their overhead size can be obtaining by running the IntegrityCheck task. 
-
 * Workaround 1: Run the IntegrityCheck task (CLI command icheck) with the -P option which will prune the MVVs. This will remove obsolete MVV instances and in many cases free up pages in which new data can be stored.  However, it will not reduce the actual size of the volume file.
 
 * Workaround 2: To reduce the size of the volume you can use the CLI commands save  and load to offload and then reload the data into a newly created volume file. See http://www.akiban.com/ak-docs/admin/persistit/Management.html#management for more information about these operations.

-# Builds the Akiban Persistit doc set.  Currently this process is based on
-# the asciidoc tool (http://www.methods.co.nz/asciidoc/).
-#
-# Here are the steps:
-# 1. Run a Java program AsciiDocPrep to prepare a text asciidoc file.
-#    Among other things, AsciiDocPrep fills in JavaDoc hyperlinks.
-# 2. Run asciidoc to generate an html file.
-# 3. Use sed to replace some characters.  Turns out asciidoc doesn't like
-#    to link to URLs having spaces, so AsciDocPrep replaces those spaces
-#    with the "`" character.  This step converts those back to spaces.
-#
-# Run this script from the root of the persistit source directory. This
-# script writes changes only into a directory /tmp/akiban-persistit-doc.
