Synopse Open Source

Perhaps it is due to a lot of projects moving from closing Google Code to GitHub, but I experimented some GitHub random communication errors since last week.

Today, we committed a new patch to enable AES-NI hardware acceleration to our SynCrypto.pas unit. Intel® AES-NI is a new encryption instruction set that improves on the Advanced Encryption Standard (AES) algorithm and accelerates the encryption of data on newer processors. Of course, all this is  […]

It appears that version 1.25 of Fossil did change the ticket storage behavior:

Enhancements to ticket processing. There are now two tables: TICKET and TICKETCHNG. There is one row in TICKETCHNG for each ticket artifact. Fields from ticket artifacts go into either or both of TICKET and TICKETCHNG, whichever contain matching column names. Default ticket edit and viewing scripts are updated to use TICKETCHNG.

As stated by the official Fossil Change Log.

Do you remember this former article about scalability of the Delphi memory manager, in multi-thread execution context?

Our SynScaleMM is still experimental.
But did pretty well, for an experiment!

At first, you can take a look at ScaleMM2, which is more stable, and based on the same ground.

But a new multi-thread friendly memory manager for Delphi just came out.
It is in fact the anonymous (and already famous) "NN memory manager" Primož talked about in his article about string building and memory managers.

(Note that in this article, our SynScaleMM was found to be scaling very well, but on the other hand, Primož did compile its benchmark program in Debug mode, so our TTextWriter was not in good shape: when you compile in Release mode, optimizations and inlining are ON, and our good TTextWriter just flies... See the note at the beginning of the article - this is why I never find those benchmarks very informative. I always prefer profiling from the real world with real useful process… and was never convinced by any such naive benchmark.)

OK, back to our business!

SapMM is an interesting beast.

Sounds like if Alexei (the initial coder) has a C coding background. But that's fine when you have to deal with low-level structures and algorithms, as required by a memory manager.
It features everything we may ask for such a piece of code: clear design, optimized code (mostly by inlining process), memory leak reporting, some parameters for tuning.

It is only for Delphi XE (and up) under Win32 by now, but contributors are welcome!
It is used in production since more than half a year, and it passed all FastcodeMM benchmark tests.

If you want a direct link of the today's source code, without SVN, you may try this direct link from our site.
(but it probably will never be updated - you are warned)

A source code repository is now available, and will centralize all future source code update.
