FPC 3.2 rc1
Great news - FPC 3.2 rc1 is released today
IMHO it's good to use fpc3.2 as primary FPC compiler for mORMot. This solve a problem with choosing correct FPC SVN revision, when FPC releases we can use package (apt / yum) to install compiler what is preferred way for CI.
Also some of my customers builds my projects from sources (they need security audit etc.) and I got a reclamation what we use "unstable" compilers. Official FPC3.2 solve this issue also.
On Linux current mORMot trunk pass all tests (except Client side * but I think this is because of some ports is used on my host) with FPC3.2 (installed from fixes3.2 fpcupdeluxe). All my products tests is also passed on Win/Lin
@ab - what do you think about switching to 3.2 ?

Re: FPC 3.2 rc1
Fixes builds the mORMot 100% perfect on my systems.
Regarding the client tests:
I always change the default http port from 8888 to 8848. Mainly due to 8888 often being used by other processes.

Re: FPC 3.2 rc1
(and anyone know if it would take weeks or months from the RC1?)
Some forum posts sound more like months than weeks.

Re: FPC 3.2 rc1
And which version of lazarus are you using together with 3.2?
I installed Fixes, which gave me Lazarus 2.0.7 and in the preliminary tests everything is OK.
Is anyone using another version? 2.1.0 maybe?

Re: FPC 3.2 rc1
What if we could say, that we support two compiler sets:
1. FPC 3.2 (RC1 by now) + Lazarus 2.0.8 (latest stable release in one or two weeks).
In practice, should we use Lazarus 2.0.7 instead? As proposed in https://sourceforge.net/projects/lazaru … rc1-44237/
Or wait for https://www.lazarus-ide.org to support FPC 3.2 + Lazarus 2.0.8 - if they will?
An official pre-compiled binary is the easiest for single target work (e.g. on Windows), to be able to test mORMot on FPC/Lazarus, especially for Delphi users.
2. FpcUpDeluxe with ........ settings (to be defined).
FpcUpDeluxe is the way to go for cross-compiling.
What do you think?
Could we wait for the Lazarus team to release stable Lazarus 2.0.8 with FPC 3.2 RC1 ? Or would they only support 3.0.4?

Re: FPC 3.2 rc1
I don't use visual components either.
The reason for updating is to get improvements in the editor.
From what I saw in the announcement of version 2.0.8 it will be for FPC 3.0.4.
So at the moment it looks like version 2.0.7 + 3.2 rc1 is still the best choice.

Re: FPC 3.2 rc1
Agreed. FPC 3.2 is the way to go. If all goes well, this will be a very good and stable release.
For sure, compatibility with actual trunk MUST be guaranteed. Trunk is the future of FPC.
But I do not expect any mORMot major breaking changes going into trunk this year.
And, any working Lazarus will do.
Personally, I use Lazarus trunk, due to cocoa and QT5 updates.

Re: FPC 3.2 rc1
@Alfred
How do we setup FPC 3.2 + Lazarus trunk from FPCUpDeluxe ?
I am trying FPC: "fixes3.2" and Lazarus: "fixes2.0".
I downloaded the latest fpcupdeluxe .x release.
It is currently building... let's see!
Result:
Ubuntu 18.04.4 LTS - Linux 5.3.0-42-generic (cp65001)
4 x Intel(R) Core(TM) i3-7020U CPU @ 2.30GHz (x64)
Using mORMot 1.18.5934
TSQLite3LibraryStatic 3.31.0 with internal MM
Generated with: Free Pascal 3.2 64 bit compiler
Time elapsed for all tests: 2m48
Performed 2020-04-05 11:58:55 by ab on devlaptop
Total assertions failed for all test suits: 0 / 43,227,911
! All tests passed successfully.
Heap dump by heaptrc unit of /home/ab/dev/lib/SQLite3/fpc/bin/x86_64-linux/TestSQL3
66492108 memory blocks allocated : 20425856622/20585961984
66492108 memory blocks freed : 20425856622/20585961984
0 unfreed memory blocks : 0So it worked out-of-the-box! Nice!
I will now try to setup the cross-compilers...

Re: FPC 3.2 rc1
Everything green! 
And the code generation did actually improve.
For instance:
?_02624:cmp rdi, rcx ; 0018 _ 48: 39. CF
ja ?_02629 ; 001B _ 77, 3C
mov rsi, qword ptr [rdi] ; 001D _ 48: 8B. 37
cmp rsi, rdx ; 0020 _ 48: 39. D6
jz ?_02628 ; 0023 _ 74, 30
mov rsi, qword ptr [rdi+8H] ; 0025 _ 48: 8B. 77, 08
cmp rsi, rdx ; 0029 _ 48: 39. D6
jz ?_02627 ; 002C _ 74, 22
mov rsi, qword ptr [rdi+10H] ; 002E _ 48: 8B. 77, 10
cmp rsi, rdx ; 0032 _ 48: 39. D6
jz ?_02626 ; 0035 _ 74, 14
mov rsi, qword ptr [rdi+18H] ; 0037 _ 48: 8B. 77, 18
cmp rsi, rdx ; 003B _ 48: 39. D6
jz ?_02625 ; 003E _ 74, 06
add rdi, 32 ; 0040 _ 48: 83. C7, 20
jmp ?_02624 ; 0044 _ EB, D2is now generated as:
?_0271: cmp rcx, rdi ; 0018 _ 48: 39. F9
jc ?_0276 ; 001B _ 72, 30
cmp rdx, qword ptr [rdi] ; 001D _ 48: 3B. 17
jz ?_0275 ; 0020 _ 74, 27
cmp rdx, qword ptr [rdi+8H] ; 0022 _ 48: 3B. 57, 08
jz ?_0274 ; 0026 _ 74, 1C
cmp rdx, qword ptr [rdi+10H] ; 0028 _ 48: 3B. 57, 10
jz ?_0273 ; 002C _ 74, 11
cmp rdx, qword ptr [rdi+18H] ; 002E _ 48: 3B. 57, 18
jz ?_0272 ; 0032 _ 74, 06
add rdi, 32 ; 0034 _ 48: 83. C7, 20
jmp ?_0271 ; 0038 _ EB, DEThere is no unneeded values moved to registers any more!
It is SO nice seeing such improvements in a pascal compiler.
Delphi didn't improve its code generator since a decade. It only introduced regressions (e.g. about FPU stack, or when inlining) on some targets.
FPC is a good shape, I can tell you!

Re: FPC 3.2 rc1
Same experience here !!
Also on ARM(64) targets.

Re: FPC 3.2 rc1
And Lazarus: "fixes2.0" is very stable.
It never crashed on huge mORMot 1.18 units!
This new Lazarus stability has nothing to compare with any version of Delphi - which all are unstable beasts.
In comparison, Lazarus is just fast and insanely stable - a real pleasure to use.

Re: FPC 3.2 rc1
I don't see any NewPascal updates anymore.
Does this means the NewPascal is deprecated?
fpcdeluxe, FPC 3.2 / Lazarus 2.0, mORMot on Windows 10 ...

Re: FPC 3.2 rc1
I think NewPascal is not deprecated, it's dead.
The guy behind it (Maciej Izak?) left the FPC/Delphi community completely or?

Re: FPC 3.2 rc1
IIRC, some of the NewPascal features have been merged into the FPC trunk?
Delphi XE4 Pro on Windows 7 64bit.
Lazarus trunk built with fpcupdelux on Windows with cross-compile for Linux 64bit.

Re: FPC 3.2 rc1
Some time ago, Maciej went through a severe personal tragedy. That has kept him away from active involvement with NewPascal.
He was also (a bit) frustrated with the amount of friction he encountered with his work for FPC.
I must agree: its hard to change anything in FPC. Bugfixes are accepted, but acceptance of (simple) changes can even take years, if ever.
But he is still around. I expect him back sooner or later.
And NewPascal is definitely on hold.
