The release.xml file was getting pretty unwieldy so break release notes into separate files. Also break contributors into a separate file. In theory most of release.xml could now be generated automatically but adding a new release does not represent a serious maintenance burden, so for the time being it does not seem worth it.

<release date="2018-07-05" version="1.29" title="Critical Bug Fix for Backup Resume">

|
<p><b>IMPORTANT NOTE</b>: This release fixes a critical bug in the backup resume feature. All resumed backups prior to this release should be considered inconsistent. A backup will be resumed after a prior backup fails, unless <br-option>resume=n</br-option> has been specified. A resumed backup can be identified by checking the backup log for the message <quote>aborted backup of same type exists, will be cleaned to remove invalid files and resumed</quote>. If the message exists, do not use this backup or any backup in the same set for a restore and check the restore logs to see if a resumed backup was restored. If so, there may be inconsistent data in the cluster.</p>

<p>Fix critical bug in resume that resulted in inconsistent backups. A regression in <id>v0.82</id> removed the timestamp comparison when deciding which files from the aborted backup to keep on resume. See note above for more details.</p>

<p>Fix non-compliant ISO-8601 timestamp format in S3 authorization headers. AWS and some gateways were tolerant of space rather than zero-padded hours while others were not.</p>

<p>Improve the HTTP client to set <id>content-length</id> to 0 when not specified by the server. S3 (and gateways) always set <id>content-length</id> or <id>transfer-encoding</id> but <id>HTTP 1.1</id> does not require it and proxies (e.g. <proper>HAProxy</proper>) may not include either.</p>
|
|
</release-item>
|
|
|
|
<release-item>
|
|
<p>Improve performance of HTTPS client. Buffering now takes the <code>pending</code> bytes on the socket into account (when present) rather than relying entirely on <code>select()</code>. In some instances the final bytes would not be flushed until the connection was closed.</p>
|
|
</release-item>
|
|
|
|
<release-item>
|
|
<p>Improve S3 delete performance. The constant <id>S3_BATCH_MAX</id> had been replaced with a hard-coded value of 2, probably during testing.</p>

|
<p>Make backup/restore path sync more efficient. Scanning the entire directory can be very expensive if there are a lot of small tables. The backup manifest contains the path list so use it to perform syncs instead of scanning the backup/restore path. Remove recursive path sync functionality since it is no longer used.</p>

<p>Make <path>backup.history</path> sync more efficient. Only the <path>backup.history/[year]</path> directory was being synced, so check if the <path>backup.history</path> is newly created and sync it as well.</p>
