Experiences using clustering with eZ publish 3.8

ez Publish version 3.8 introduced a specialised clustering functionality that allowed for the storage of all content related caches, images and binary files in the database. All other files are stored on the local file systems.

This is a great improvement over previous versions of eZ Publish that did not include any specific clustering support.

In a recent install we utilised the clustering functionality and found a number of issues that are not highlighted in any of the documentation.

In our setup there are 2 web servers. Both systems serve the site while one was designated the "master" and used for administration.

Our design uses the toolbar functionality to allow editors to add and update content that appears in a right hand column.

Synchronisation of toolbar.ini files from the mater server to the slave is performed using rsync.

After a while inconsistencies in the display of toolbar content was noticed. In tracking this down it was discovered that the toolbar parameters are …

Microformats

One of the buzzes in the web world at the moment is microformats (all part of this web 2.0 thingi). Basically microformats take the whole semantic web to the next level. Where valid markup uses correct tags to indicate headers, lists and tables, mircoformats use a combination of tags and class names to represent specific structured data.

The first 2 structures that this has been applied to are vcard & icalendar - the microformat equivalents are hcard and hcalendar. Formats also exist for reviews,resumes,relationships etc.

Microformats are a way of taking information that already exists and adding structure to allow the information to be parsed.

So whats the point? Imagine google indexing the site not just for plain text for for specific event information, being able to click on contact information or an event and adding it in your address book or calendar, clicking on an address and seeing it's location (and getting directions) from google maps?

The great thing is that it'…

eZ publish EXIF stripping followup

It's been 2 weeks since the stripping of EXIF data was put into place on the willow site. Last friday a redesign up uploaded and as part of this update I added the EXIF stripping to all the images on the site.

The following table shows how these changes have effected the size of downloads:

Week / Action
Bytes Transfered Sessions Bytes / Session Week 1 - no image changes 2.50 GB 6,969.00 376.45 KB Week 2 - striping EXIF data from thumbnails 1.81 GB 7,459.00 254.95 KB Week 3 - striping EXIF data from all site images (minor design changes) 992.98 MB 8,459.00 120.20 KB
As the number of sessions has increased over the period I've used the Bytes/ Session to calculate that stripping the EXIF data from all images has resulted in a saving of approximately 30% (this figure is likely to be effected by the new lighter site design).

These changes have resulted in the site loading much quicker, especially the collection pages that contain a lot of thumbnails.

Those looking f…

Reduce thumbnail size in eZ publish by stripping EXIF data

Have been working on a refresh of the willow site and could not work out why the majority of thumbnail images were 20K yet others were 2K. I stumbled on the issue when a bug with the handling on EXIF data presented itself.

When ImageMagick scales images it will copy any EXIF data unless told not to. The images on the willow site contained approximately 18K of EXIF data and this was being copied into the thumbnail variations.

eZ publish makes it easy to add filters for image variations. Simply add the following line to image.ini.append.php in your siteaccess file:
[ImageMagick]
Filters[]=strip=+profile "*" +comment

[small]
Filters[]=strip=
This will strip EXIF information for "small" image variations and can be added to others by simply adding the Filters[] line to the variations definition.

Newer versions of ImageMagick have a -strip flag that will also remove EXIF data. To use this replace the [ImageMagick] section with:
[ImageMagick]
Filters[]=strip=-strip
This will wor…
