Embed Small and Optimized Debug Information for FPC

By Arnaud Bouchez, 2021-06-26. Open Source › mORMot Framework

Debug information can be generated by compilers, to contain symbols and source code lines. This is very handy to have a meaningful stack trace on any problems like exceptions, at runtime.

The problem is that debug information can be huge. New code style with generics tends to increase this size into a bloated way...
On Delphi, mormot2tests generates a 4MB .map file;
on FPC, mormot2tests outputs a 20MB .dbg file in DWARF.

For Delphi, we propose our own binary .mab format which reduces this 4MB .map file into a 290KB .mab file since mORMot 1.
Now mORMot 2 can reduce a FPC debug file of 20MB into a 322KB .mab file!
And this .mab information can just be appended to the executable for single-file distribution, if needed, during the build. No need to distribute two files, potentially with synchronization issues.

Enhanced HTTP/HTTPS Support in mORMot 2

By Arnaud Bouchez, 2021-05-14. Open Source › mORMot Framework

HTTP(S) is the main protocol of the Internet.
We enhanced the mORMot 2 socket client to push its implementation into more use cases. The main new feature is perhaps WGET-like processing, with hashing, resuming, console feedback, and direct file download.

Enhanced Faster ZIP Support in mORMot 2

By Arnaud Bouchez, 2021-05-08. Open Source › mORMot Framework

The .zip format is from last century, back to the early DOS days, but can still be found everywhere. It is even hidden when you run a .docx document, a .jar application, or any Android app!
It is therefore (ab)used not only as archive format, but as application file format / container - even if in this respect using SQLite3 may have much more sense.

We recently enhanced our mormot.core.zip.pas unit:

to support Zip64,
with enhanced .zip read/write,
to have a huge performance boost during its process,
and to integrate better with signed executables.

OpenSSL 1.1.1 Support for mORMot 2

By Arnaud Bouchez, 2021-02-22. Open Source › mORMot Framework

Why OpenSSL? OpenSSL is the reference library for cryptography and secure TLS/HTTPS communication. It is part of most Linux/BSD systems, and covers a lot of use cases and algorithms. Even if it had some vulnerabilities in the past, it has been audited and validated for business use. Some algorithms […]

Fastest AES-PRNG, AES-CTR and AES-GCM Delphi implementation

By Arnaud Bouchez, 2021-02-13. Open Source › mORMot Framework

Last week, I committed new ASM implementations of our AES-PRNG, AES-CTR and AES-GCM for mORMot 2.
They handle eight 128-bit at once in an interleaved fashion, as permitted by the CTR chaining mode. The aes-ni opcodes (aesenc aesenclast) are used for AES process, and the GMAC of the AES-GCM mode is computed using the pclmulqdq opcode.

Resulting performance is amazing: on my simple Core i3, I reach 2.6 GB/s for aes-128-ctr, and 1.5 GB/s for aes-128-gcm for instance - the first being actually faster than OpenSSL!

New AesNiHash for mORMot 2

By Arnaud Bouchez, 2021-02-12. Open Source › mORMot Framework

I have just committed some new AesNiHash32 AesNiHash64 AesNiHash128 Hashers for mORMot 2. They are using AES-NI and SSE4.1 opcodes on x86_64 and i386. This implementation is faster than the fastest SSE4.1 crc32c and with a much higher usability (less collisions). Logic was extracted from the Go […]

mORMot 2 Proposal: Rename RawUTF8 Type As Utf8 ?

By Arnaud Bouchez, 2020-12-29. Open Source › mORMot Framework

One proposal for mORMot 2. What if we renamed the RawUTF8 type into Utf8? With a default compatibility redirection if PUREMORMOT2 is not defined, of course. The "Raw" prefix came from early mORMot code, which used TRichView as reference for the UTF-8 encoding... but it is clearly an […]

mORMot 2 Entering Testing Phase

By Arnaud Bouchez, 2020-11-16. Open Source › mORMot Framework

After a lot of work, our mORMot 2 fork is entering its testing phase.

The main /src/core /src/lib /src/net /src/db /src/orm /src/soa /src/app folders of our Source Code repository have been implemented.

Please check https://github.com/synopse/mORMot2 for the latest version of the source code. The README.md files on each folder would help you discover the new framework design, and the content of each unit.
