Apache Roller 5.1.2 Released!

03.30.2015 by Glen | 0 Comments

Apache Roller 5.1.2 has been released and is available for download here Roller download page.

This release takes care of a potential security problem involving bloggers with admin permissions on a blog being able by default to execute arbitrary code on the server hosting Roller. As a reminder, even without this issue, as bloggers can blog and instantly post anything and everything including copyrighted, privacy-infringing, and other objectionable content, do not grant blog-writing accounts above the "Limited" role (can edit but not post blog entries) to people whom you do not thoroughly know and trust.

Below is the list of fixes and enhancements over Roller 5.1.1:

  • ROL-2057 - Missing NPE check in Roller PageServlet class
  • ROL-2058 - No salt renewal on POST request
  • ROL-2059 - Comment preview is invisible in Gaurav theme
  • ROL-2060 - Missing custom.css import in tags_index.vm in Gaurav theme
  • ROL-2061 - Wrong next month link of Calendar
  • ROL-2062 - Missing NPE check in IndexOperation#getDocument()
  • ROL-2064 - Add viewport meta tag to Gaurav theme
  • ROL-2065 - Gaurav sometimes displaying empty summary as unresolved "$entry.summary"
  • ROL-2066 - Comment URLs using https:// not saving properly in Gaurav theme
  • ROL-2067 - Velocity configuration improvement

Apache Roller 5.1.1 Released!

10.01.2014 by Glen | 0 Comments

Apache Roller 5.1.1 has been released, offering the following fixes/enhancements over Roller 5.1:

  • ROL-1387 - In creating tag aggregate counts (for tag clouds, etc.), count tags only from published blog entries
  • ROL-1620 - Plus signs in Category names result in 404s for Atom and RSS feeds
  • ROL-2050 - Have Design Tab default to Templates page when custom themes are being used (speeds up template customization)
  • ROL-2051 - Themes not falling back to standard templates when mobile ones undefined (affecting ability for Roller to be read from tablets and smartphones.)
  • ROL-2052 - Custom stylesheets not being updated correctly when user switches between shared and custom themes.
  • ROL-2054 - Newly saved categories not appearing on blog
  • ROL-2055 - Comment search should be case-insensitive

Update needed for Roller 5.1 blogs to display on smartphones/tablets

09.02.2014 by Glen | 0 Comments

Note (1 October 2014): Below problem has been fixed with the latest Roller 5.1.1 release.

Apache Roller 5.1 has a bug in which the standard blog theme templates are not being activated when no mobile theme templates are defined, resulting in blogs not being readable in most cases from tablets or smartphones. (Roller 5.1 now allows the option of separate templates, called template renditions, for mobile and standard displays, however the standard rendition is supposed to be activated when a mobile rendition is not defined.) I've just committed a fix to this problem in Roller trunk, i.e., the future Apache Roller 5.1.1. Until we have a new release, here are some solutions to this problem:

  • Upgrade to a snapshot version of Roller containing the fix - Providing you've already upgraded to Roller 5.1, switching to a patched version should be just a simple switch of the WAR file. First checkout and build Roller tag and redeploy the WAR. You can alternatively just deploy Roller 5.1.1-SNAPSHOT (i.e., trunk), which at the point of publication of this blog entry is the same as the above tag, however with additional commits to the trunk over time bugs and incompatibilities may pop up as we develop the code. As with any upgrade, good to manually back up any custom (modified) templates and stylesheets so you can bring them in again if a problem occurs in the upgrade, however this particular patch should not have any effect on customized templates.

  • Switch to the basic-mobile theme. This theme already has separate mobile and standard renditions explicitly defined in its theme.xml descriptor.

  • For shared themes in the WEB-INF/themes folder of the WAR, in the theme.xml (for example here for basic), duplicate each rendition, marking one for standard and one for mobile, just as done right now with the basic-mobile theme. Such a change will result in Roller 5.1 picking up the same template regardless of device type. If you've customized a shared theme however, back up your templates as you will probably need to copy them over once you re-import the new shared theme.

Apache Roller 5.1 Released!

08.25.2014 by Glen | 0 Comments

Announcement email here. Download and give Roller 5.1 a try! As mentioned in the email, for Roller users upgrading from previous versions, make sure to back up your current Roller database prior to doing the upgrade in case problems occur and you need to roll back to your previous Roller instance.

Upgrading Roller 5.1-SNAPSHOT database instances

07.07.2014 by Glen | 0 Comments

Apache Roller trunk (i.e., 5.1-SNAPSHOT) will automatically upgrade any Roller database that was part of an official release from Roller 3.1 onwards during its install process. Follow the Apache Roller installation guide for more information on this process, including making sure that you do a safety back up of your database prior to running the install.

However, for those who have earlier deployed unreleased 5.1-SNAPSHOT versions, neither later 5.1-SNAPSHOTs nor the future release 5.1 will be able to automatically upgrade your SNAPSHOT database, which will create a incompatibility issue if database changes occurred in development since the snapshot version you deployed. This will necessitate some manual database upgrade changes prior to moving to the later version of Roller.

To determine if any manual database changes are needed, check the revision number located on the footer of the Roller login page, i.e., the (rXXXXXX) value at the end of the "Powered by Apache Roller Weblogger Version 5.1.0-SNAPSHOT" string. Then, using the source control repository of the createdb.vm file, do a comparison (using the "select for diffs" links) between versions of the file immediately preceding that version number and either the latest version of the file (for a future 5.1-SNAPSHOT) or the version just before but no later than the release date of Roller 5.1.

For example, here is a comparison between March 2014 and May 2014 database instances. Note the createdb.vm does not provide the actual SQL statements needed for your particular database instance (as that will vary depending on the database you're using) but just the pseudocode SQL informing you which tables and columns need deletion, creation, modification, etc. Check your database's manuals for information on the necessary SQL statement syntax for table alterations, and of course back up your database first.

Language Support for Upcoming Roller 5.1

07.07.2014 by Glen | 0 Comments

Apache Roller 5.1 is expected to be released "soon" (no fixed date yet available). For the Apache Roller trunk branch (i.e., upcoming 5.1), I recently cleaned out the language resource files of unused strings that have accumulated over the years and also introduced generic.* property strings for common functions (Save, Edit, Delete, etc.) that are used in multiple places to further reduce the number of strings that need translation. As a result, each of the language files shrank 25-35%, with the results browsable online. As one can see, Roller 5.1 will be shipping with support for English, Spanish, French, German, Russian, Chinese - Simplified, Japanese, and Korean. (By language support, I'm referring to the user interface for administering your blog--creating blog entries, managing comments, etc.--and certain boilerplate text within your blog templates. For writing blog articles and customizing your blog templates, Roller supports virtually any written language desired.)

However the non-English languages have only between 30-50% of the total strings (roughly 1800 in all) translated. Any strings missing will appear in the default English. If you're looking to deploy Roller in an office or school and wish to have better support for a given language, now would be a great time to check out Roller trunk from Subversion and submit a patch to our JIRA issue tracker, translating some-to-all of the missing strings of your desired language. IntelliJ IDEA Community Edition provides an easy-to-use editor to identify and translate strings present in the English but missing in the other files, and Eclipse offers similar.
