DelphiUdIT

Hello ALL. I make a repository with a copy of original Indy repo with all changes to help updating Athens 12.1 Indy version and make it compatible with the IDE and third-party components. https://github.com/SiveaITA/Indy-Athens12.1 Please Remy give a look. UPDATE: seems that what I have done is not the right way, so the repository will be shutdown.

Some changes are refuses from Indy team, 'cause some of them (changes) are only for the next new release (11), like I write in the recent post. Other motivations surely there are. This repo exists only to help everyone that want to update the Indy version that came with IDE. That is still with legacy technologies (no Oauth2, no TLSv1_3), and the Indy official repo is not compatible with Embarcadero and some tirdh-party components (like those installed from getit that need Indy). If this is not the right way, I switch the repo in "private" ... no problems. You are right about Remy, I don't want any test from him, my request may be misunderstood.

Look there, or you should wait...

In the batch "clean..." there was an error ... "ren" cmd is not working if the destination file name has a path. In the normal condition (without extension options) this is an error. So I change the cmd file, including the new directories for Athens12.1 in the zip file attached. Clean_IDE.zip

Right observation

@Chief I had the same issue, but if you go inside in one post, automatically you will be added to enabled group. Go there for example (taken form another post): https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-441 Bye

Yes, and I tried it this time (I mean now). My apologize to don't advertise you in time, but in my system (with standard installation of Rad Studio, so in "c:\program files (x86)\....") and of course with admin priviledge the files indicated where not backuped ("cannot backup xxx" was the message, the rename did't work ???) ... the files were deleted. In the weekend I try to understand what was the problem. Another thing about this topic: in that "cmd files" some changes are needed cause new distribution of the files in Athens 12.1 (some bpl in bin64, new "MODERN" compiler, IOS simulator) . I already adjusted the file, but I should test it (and look for backup issue).

Oh yes, I remember something about Delphi7 ... but now these things should never be present, neither like options ... a code refactoring is a must. We are talking in these days about safe memory .... and there are still those "options". But this is my personal opinion.

In Delphi is allowed to change typed const, look here ... simple, if the relative option is set. Never used ... is terrible...

Constant when you write the code, variable when the code is running

Here some posts about that (read ALL). The referring page is: https://github.com/IndySockets/Indy/wiki/Updating-Indy Take care: by now, the Indy github version is not full compatible with Embarcadero distribution. I should change some things inside (in the posts are indicated, but still confusing ... sorry for that). One for all: don't use the automatic procedure !!!😞 After the changes of Indy "clear cmd" about some files that should not be deleted, in my system they are deleted instead ... use manual mode like I indicated in my posts. Unfortunately I am not familiar with github and so making a replica of the Indy repository with the necessary corrections is difficult for me. Furthermore it is necessary to copy and compile some sources provided by Embarcadero, which obviously I am not authorized to distribute and I can only indicate how to proceed. Some of these fixes are correctly rejected by the Indy team because they are only planned for the next release (11), and so those are not in the Github repo. Bye P.S.: with those actions you'll have the ability use of TLS1_3 and the OpenSSL library 3.1.4 (I use those) and OAuth2 (not tested by me). I'll try to create a repo and put all things inside with a readme.

Hallo, i tried to update the standard distribution of Indy with the github version (ssl-oauth + PR), like for 12.0 version and all is working, also for LivePreview for FMX. The only exception is the package "Embarcadero RAD Server Edge Components" that which causes an AV closing the RAD STUDIO. By disabling this package (which I don't use) the problem does not arise. I recompile a bunch of working project with Indy and all is OK

I don't develop this kind of analysis for mobile and I don't know if there are math libraries that do that on those devices, but for example on IOS you have this function: https://developer.apple.com/documentation/coreimage/cirectanglefeature But I really don't know if it's exposed on FMX. For Android I don't know ....

@shineworld use the last link ...

Try to use PasLibVlc ... can play whatever you want and it's fast (you should have installed VLC). You have the full control on the stream media. https://prog.olsztyn.pl/paslibvlc/

Like exe, the DLL have a field in the IMAGE_OPTIONAL_HEADER64 - DllCharacteristics that enable or not the ASLR. In effect lot of DLLs are not ALSR compatible (especially the old ones). And they should works whenever ASLR is ON or OFF. https://learn.microsoft.com/it-it/windows/win32/api/winnt/ns-winnt-image_optional_header64 Security things a part of course. Some my customer more then 10 years ago explicity want the ASLR flags On and DEP too in my applications. And that works because some libraries that the customer forced me to use were not ALSR compatible (and neither was the application obviously ). Some years ago also ASLR HE was imposed, and all worked well. For this I asked the full compatibility of ASLR (HE) of C++ DLL.

I don't have links, the discussion was in one webinar where I post some questions about C++, one of them was about ASLR, since they introduce set on by default (I used them before that with the PEFLAG settings). And the answer was the they are not sure about use the ASLR with Delphi and a C++ DLL. I used them before, I used them now and I had only a little problem with third part library (ASLR HE cause AV). Of course, like @David Heffernan said these is only meaning that the code is not write in the correct way ... but if those is about the C++ base environment, you cannot do nothing about, only try to "stem" the problem. I don't want to create alarms. only report what it's said about that. But for sure if ASLR create problems, some parts of the code are bad written. Another point is that Windows does not impose (force) the use of ASLR by default and that the same ASLR exclusion options are present in the Delphi project. This means that it is absolutely known that incompatibilities with ASLR exist (perhaps with legacy software) and that the exclusion of this option, even if it is a last resort, is possible.

I agree with you on what you say, the pointer problem is indeed a problem, and obviously needs to be solved. But the incompatibility with 64-level DLLs and ASLR is well known: at one of the webinars, following a direct question of mine on this very topic (we were talking about DLLs with C++ and Delphi), it was confirmed that full compatibility between 64-level DLLs and ASLR could not be guaranteed when developed with C++ (Embarcadero). We talked about this a few months ago. Whether the problem is with the C++ libraries (perhaps some still 32-bit pointers?) or something else has never been clarified. However, I correctly use 64-bit DLLs developed in C++ Embarcadero with ASLR and ASLR HE without any problems.

I think the problem is the project options: in the new 11.3 (like 12) environment the additional setting about ASLR are ON, try to deselect them.

@pcoder, @Stefan Glienke I think he wants to try a general function, also for others rounding modes (he inserts other masks to the function). But you are right, there are also other native CPU instructions that do that specif works (like that you exposed).

But use the "grep" tool on command line to check where the unit are related, in all files (in all disk if necessary 😉) ?

But is not forbidden:

If you must use NEW (so create a new variable), why don't declare it like a normal variable or a typed pointer? If you refer a record variable you don't need to allocate memory. If you need to reference a pointer, this normally means that it's already assigned and you can cast without NEW or DISPOSE. Another suggestion: in Delphi you don't need to "defererence" a typed pointer, the compiler do it for you: var LPointer : Pointer; begin New(PMyRec(LPointer)); PMyRec(LPointer).Int := 200; PMyRec(LPointer).Str := 'Blah'; Dispose(PMyRec(LPointer)); end; var LPointer : PMyRec; begin New(LPointer); LPointer.Int := 200; LPointer.Str := 'Blah'; Dispose(LPointer); end;

I don't understand what is bad here. "FloattoJson" means transform a float value in Json reppesentation ... and this means that should be ".x" in the case that there are not "." or "E" symbol. This is true and not questionable, but the real meaning to know if that Json format is a "standard" float or a currency is in this phrase: So, I can write this values: (1) <- May be a integer, but you can read it like "base 10", binary, hex, octal .... (1E0) <- May be a integer, but also a float (and I saw the scientific notation generally is taken like a float) and yes it's "base 10" (1.0) <- It's a float "base 10" or currency ? (1.00) <- It's float "base 10" or currency ? But all this representations are subjective to Json ....
