Heh, ok I guess missed that (announcement?). Still, breaking the repository up into multiple smaller chunked files is a good idea, which is what Magma now does instead of appending endlessly to the same files.

What "2GB file-addressability" limit are you referring to? There is no such thing. Files have been 64 bit for a couple of years now so unless you run some really, really old VMs that limit doesn't exists.

I am pleased to announce release 40 of the Magma object database for Squeak, offering a significant boost in robustness from the previous version:

  - No longer constrained by Squeaks 2GB file-addressability, Magma can

now support unlimited file sizes (configured out of the box for up to 281 Terabyte sized files). - Full backups are now truly "live", with no pause in service. - There is now support for a "warm backup," for rapid failover capability.. - ..and server load distribution for clients that can tolerate a slightly-behind, read-only repository (i.e., for reporting, archive retrieval, etc.). - The MagmaCollectionIndex hierarchy is no longer required on the server. - The server correctly ignores garbage bytes sent by hackers to its listening port. - Other enhancements and some important bug fixes.

Nearly every feature and fix has originated at the request of members of the Squeak community. This is your database. I plan to continue supporting, improving, and ensuring you have a good experience using Magma. Please tell me what you need on the Magma mailing list.

This one single code-base has been installed and tested successfully in the 3.7, 3.8, 3.9, Tweak, Croquet 1.0SDK and sq3.9-7067dev07.07.1 images. Other images may work, I just haven't tested them, you can use the "Magma tester" to find out. In images without MethodProperties (3.7 and 3.8), Monticello will provide a friendly pink warning that a few extension methods will not load. This is ok, just press Proceed. It's better than maintaining different code bases for each version of Squeak.

Since its earliest days, Magma has been a "one-click" install and this version is no different. There are three configurations available on SqueakMap and SqueakSource; "client", "server" and "tester". The former simply exclude certain packages that are not needed for that function.

So, does that mean that the .changes file collapse in 3.9 was unnecessary? I thought this limit was the cause of the compresssed sources in 3.9.

Not at all. That's a problem of how source file pointers are represented in the image, not how large a file can be.

Sig contributed a simple change that lets you plug whatever dictionary you want. This is included in this release, so you can set it up as part of your application-initialization.

But sig's new Dictionary's themselves arrived too late to incorporate as the default into this release. There is much testing and measuring and comparing with other Dictionary solutions (such as those from Martin Loewis) needed before making a switch to a new default Weak Dictionary.

I don't know, maybe better was to keep my dictionaries as separate package. Previously, i had a package with 'B' single prefix in class names. But then, since i implemented them mainly for use with magma i decided to rename them with Ma prefix and replace existing ones directly in magma.

And please, let me remind you, that magma uses two kinds of weak dictionaries: WeakIdentityKeyDictionary and WeakValueDictionary Previously i added a way to choose only one of them in MagmaPreferences class (for WeakIdentityKeyDictionary).

Now, i added snapshot, which fills the gap, and also makes use of it in MaOidManager and MagmaOidManager code.

Now, there's no direct references to any weak dictionary classes within magma client code, they are rely on those, which set in MagmaPreferences.

see Magma client-sig.258 in magma-tester repo. It based on Magma client-cmmr50.256.

Great I'll test it with my app right away ! Does it include collection optimisation from sig or others ?

I wanted to install the magma-seaside package but I got an error with this version :

This package depends on the following classes: WADispatcherControlPanel You must resolve these dependencies before you will be able to load these definitions:

Although this class was part of seaside, it was not part of the "maintained" core of seaside, and so I started Seaside28Jetsam as a package for collating small seaside extras.
