Ubooquity 1.10.0

08 may 2016    Release

Ubooquity 1.10.0 is available.

Update: 1.10.0 has been replaced by 1.10.1 which contains a fix for reading secured PDF documents and prevents the usage of Java new color management library (LittleCMS) which is apparently absent from some systems.

New requirements

Starting with this version, Ubooquity requires Java 8.
(Java 7 support by Oracle stopped more than a year ago, time to upgrade !)

Fixed bugs

  • Fixed PDF rendering problem caused by some versions of Java (cf forum)
  • Fixed user authentication not working when shared folders are symbolic links (cf forum)

Detailed explanation

  • About PDF
    Apparently, the old library used by Ubooquity for PDF rendering has been broken by recent updates of Java (both 7 and 8). This library has been removed and all PDF (books and comics) are now renderend by an updated version of PDFBox, which happened to improve a lot recently.

    Among the consequences is a probable performance hit (CPU and memory) for some people as JPedal (the old library) was faster than PDFBox. On the other hand, almost all properly formed PDF can now be read online provided your device is powerful enough.
  • About symbolic links
    If activating user login prevented you from seeing your shared folders content (as described on the forum), you might have  shared (knowingly or not) a symbolic link instead of an actual directory.
    Ubooquity now supports symbolic links: to fix the issue, just edit and save your books/comics settings again.

Ubooquity 1.8.0

22 june 2015    Release

Ubooquity 1.8.0 is available.

Update: 1.8.0 has been replaced by 1.8.2 which contains a bug fix for the reverse proxy feature

New requirements

Starting with this version, Ubooquity requires Java 7 or later.

New features and improvements

  • Cache management
    Ubooquity now provides caching information to your browser. This will avoid unnecessary file transfers and save bandwith.
  • "host" option
    By default, Ubooquity binds itself to all available network interfaces. This new command line parameter allows you to specify the hostname Ubooquity should use when configuring its binding.
    Example: if you launch Ubooquity on your local machine (with the address, for instance), you will be able to access it with your browser on localhost:2202 and Now if you add "--host" to your command line, localhost:2202 won't work anymore.
  • "workdir" option
    This new command line parameter allows you to specify where Ubooquity should create its own files (database, logs, preferences, cache, etc). The "user.dir" method, sometime mentionned on the forum to achieve the same result, is not reliable. You should use the new setting instead.
  • Comics folder customization
    When displaying your comics grouped by folder, you can now add images and text to customize the appearance of theses folders. (cf forum request)

    Add a "folder.jpg" image (also works with png and gif) in your folder to have this image displayed instead of the usual cover.
    Add a "folder-info.html" file in your folder to have its HTML displayed on top of the content of the folder. The HTML can use other elements contained in the folder (like images, style sheets, etc) as long as their source path starts with "[[FOLDER]]" (e.g. src="http://vaemendis.net/ubooquity/[[FOLDER]]/dcComicsLogo1.png" ).
    If you want to give it a try, download this example folder. Unzip it, share it, and see how it's done.
    To use this new feature, "Folder metadata display" has to be enabled in the advanced options.
  • New comics reader
    The comics reader has been rewritten from scratch to make it more usable and add "fit to width/height" options, as well as an automatic split of double pages. (cf forum discussion)

  • New command line format
    Command line paramaters should now be passed with a "--" prefix instead of "-" (although the old syntax is still working). Here is the complete list of available parameters:
    Option                           Description
    ------                           -----------
    --debug                          Activate debug mode
    --headless                       Prevent Ubooquity from displaying a
                                       desktop user interface
    --help                           Display command line help
    --host <hostname or IP address>  Specify the hostname or IP address to
                                       which Ubooquity is going to bind
                                       itself to
    --port <Integer: Port number>    Specify on which Ubooquity is going to
    --webadmin                       Activate the web administration page
    --workdir <directory path>       Specify the working directory of
  • Extended exclusion pattern
    The settings previously called "Folder exclusion pattern" (now "Scan exclusion pattern") has been modified to include files as well. Now, any file or folder whose path matches the regular expression defined by this parameter will be ignored by Ubooquity. (cf forum request)

Fixed bugs

  • Fixed "raw files" not working on Linux/Mac OS (cf forum)
  • Fixed a problem with rendering PNG files using color type 6 (cf forum)
  • Fixed reverse proxy for OPDS feeds (cf forum)
  • Fixed database path bug (cf forum)
