Net::Clacks Important data corruption bugfix released

    I usually try to avoid clobbering the PM News section with release information about my modules. But i found a problem in my Net::Clacks::Server which can, under the wrong circumstances, either prevent startup or lead to all sorts of data corruption in cached data.

    I have fixed this in Version 18 (at least i think it is completely fixed, bug reports are welcome).

    Unfortunately, this upgrade features an incompatible change that clobbers the persistance file. There is a workaround for that to keep your cached data, though. From the UpgradeGuide.pod:

    WARNING: BREAKING CHANGES regarding persistance files.
    Version 18 provides better reliability for the Clacks Server when using a persistance file, including startup problems and prevention of data loss.
    Here is the problem in older versions: If the server process is killed while writing the persistance file, the file on disk may be invalid (partial data) or completely blank. Blank files at least prevented the server from starting up, but otherwise incomplete files could lead to data corruption in cached data and/or all other sorts of problems. This relates to the fact that the server only does very minimal checks on its internal cache during runtime for performance reasons. The original persistance file was just a quick hack to dump/restore the cache between runs and did not account for system crashes or the process being killed while writing to disk.
    This new version of Net::Clacks::Server tackles this in in a multi-stage approach:
    1.) The persistance file now includes the ENDBYTE string as a third line. This is used to check if the file is complete.
    2.) Before overwriting the current persistance file, it is COPIED to a file with '_bck' added to the configured name.
    3.) The file is written under a new name (with '_' added at the end) and then MOVED over the correct file name. File move (rename) within the same directory should be an atomic operation of the operating system, so it either works or doesn't (no stopping half-way inbetween).
    4.) An invalid persistance file doesn't prevent the clacks server startup. If it detects an invalid file, it first tries to load the previous version ('_bck'), then as a last desperate measure to prevent data loss, it tries to load the temporary file ('_'). If that also fails, it starts 'blankety-blank'.
    Clacks caching was always designed as a CACHE, not as the final storage for important data. This upgrade to Version 18 changes the file format of the persistance file slighty. The older format is now detected as invalid, resulting in a "blankety-blank" startup. If you really want or need (?!?!?!) to preserve the cached data for some reason, there are two ways to accomplish this:
    1.) Stop the clacks server and upgrade the Net::Clacks package. Edit the persistance file and add a third line with the word "ENDBYTES" without quotes as its only content.
    2.) If you are running a master/slave setup with interclacks, you can stop ONLY the server that has the persistance file. Then upgrade Net::Clacks and start the server. It should start "blankety-blank" and automatically resyncronize cached data from the interclacks network. It works the same if all your clacks servers use persistance files for some weird reason, just restart them one-by-one, waiting inbetween for the interclacks sync to finish. You can use the example Connect to the server you keep running and start the MONITOR command. While interclacks sync is in progress, you will see KEYSYNC commands flying between the servers. If you stop seeing them for a few seconds, KEYSYNC is finished.

    Hello folks!

    other news (thuesday of past week) for the no|one|many perl community: the #perl irc channel moved from freenode to

    > May we live in less interesting times

    The above quote from (one of?) the announcement

    Infact there was a massive migration from freenode to libera.

    If you connect to the #perl old channel on freenode you will be automatically redirected to the ##perl channel not owned by previous people.

    Relevant articles: freenode_staff_resigns and freenode_the_mainstream_irc_network_is_collapsing

    There is also a youtube resume of the mass migration

berrybrew version 1.34 released!

    I've released version 1.34 of berrybrew.

    Notable changes:

    • UI elements now update on the fly, so all changes are reflected immediately
    • You can 'use' any version of Perl you've got installed from the UI, which'll open a new CLI window set to the selected version
    • You can now fetch the updated list of Strawberry Perls available through the UI
    • Cloning installed Perls as well as a myriad of other operations can now be done through the UI
    • The API has been updated so that internal objects are updated live-time. This makes having long-running processes possible
    • Build/Test infrastructure updates
    • Documentation updates
    • Minor bug fixes

    I've just got a new full time job, programming in Perl... finally, after several years of looking for that perfect work environment. Some of it will be on Windows (which I haven't used except for developing berrybrew), so I'm actually looking forward to using my own software, especially how useful its become thanks to the new UI I've developed.

    Happy Perling!

    This is actually from last August, but I haven't come across it until today.

    Marketing Strategy for the Next Two Years (

    The question for us, I think is: What impact will this have on PerlMonks? Will we be required to modify/restrict our "look and feel" to conform to the branding guidelines set by TPF?

    I reckon we are the only monastery ever to have a dungeon staffed with 16,000 zombies.

    Aron Wall quotes his dad Larry Wall in an interesting blog post:

    As my Dad said in an interview once about the philosophy that motivated him to make the Perl programming language:

    The philosophy of TMTOWTDI ("There's more than one way to do it.") is a direct result of observing that the Author of the universe is humble, and chooses to exercise control in subtle rather than in heavy-handed ways. The universe doesn't come with enforced style guidelines. Creative people will develop style on their own. Those are the sort of people that will make heaven a nice place.
