Trust me I have been through all of this Indian shit(I am one)

Joesph

The curiosity to learn,the curiosity to do things, the curiosity to make something

Joesph

This is study once you pin point your goal all is left is learning

Joesph

Tell me anyone in college told you about gnu tools,de,Linux kernel?

Joesph

The answer is no

Joesph

And I do know about the things and I don't follow indian college shit I am way more beyond what they are teaching me at college I am just there for degree but I got knowledge more than that

Joesph

Rest info @K11M1

The answer is no

Don't be so sure :) I've had a class on Operating Systems which covered basics of Linux, Windows I know a master's program that covers how Linux works, Linux kernel, etc as one of classes

Linux work?

my admin tag? i asked roxi for it

Joesph

Linux kernel?

Joesph

These are the things I learned when I was 12

It's not the place to show off

Joesph

my admin tag? i asked roxi for it

But Newbie that doesn't fit well tho

Joesph

It's not the place to show off

The answer is accept the truth

Mateo

The answer is accept the truth

To be a respectable person you need to know when to be arrogant and when to be humble, you aren't going anywhere being arrogant here

Joesph

To be a respectable person you need to know when to be arrogant and when to be humble, you aren't going anywhere being arrogant here

The truth is I am straight forward I say things straight forward I know it hurts but it saves my time and by time they realize one day what I said

Joesph

So yes let me be arrogant

Hi programmers

Noble Friend

Hi. Welcome

Hii

Foxner

Hi. Is it possible to push to and pop from the call stack directly in C++?

Mar!o

Use inline assembly

...

Use inline assembly

why would you do this? there are no to little cases where this makes sense for problem above

Mar!o

Because you can push and pop to the callstack directly using asm thats what he wanted

Mar!o

But its not the best solution okay...

...

this is correct, but if you push / pop something you want to accomplish something, eg. calling a function

...

and in 99% of the cases, no compiler will generate a crazy custom calling convention where this is necesarry

Mar!o

Yep thats right. But still sometimes asm has its uses especially with naked functions for drivers etc..

I want to know what's wrong with drogon when connecting to mysql.

I want to know what's wrong with drogon when connecting to mysql.

Docs are lacking compared to the other part of the lib, esp when making connection.

Tom

Sorry, I'll add this part. And U could find something useful for making connections on https://github.com/an-tao/drogon/wiki/08.1-DataBase-DbClient

Please

Yea, I've read that. But no way to input password ? I do sth like this in soci. string s = fmt::format("db={} user={} password='{}'", cfg.db_name, cfg.db_user, cfg.db_pass); session sql(soci::mysql, s);

Tom

In drogon, all connections are managed in DbClient, you can think of DbClient object as a connection pool.

I know that

Tom

you could set password in the connInfo argument.

Ибраги́м

It's common design methodology

Ибраги́м

One Client, multiple conn.

Tom

Or create the DbClient in configuration file, see https://github.com/an-tao/drogon/wiki/10-Configuration-file#db_clients

Ибраги́м

I've read it all before, didn't want to use "config" file.

Ибраги́м

you could set password in the connInfo argument.

Where it should rightly be.

Ибраги́м

pass='' or password=''

Tom

auto clientPtr = DbClient::newPgClient( "host=127.0.0.1 port=5432 dbname=postgres user=postgres password=xxx", 1);

Ибраги́м

shite, passwd ?

Ибраги́м

auto clientPtr = DbClient::newPgClient( "host=127.0.0.1 port=5432 dbname=postgres user=postgres password=xxx", 1);

terminate called after throwing an instance of 'drogon::orm::BrokenConnection' what(): No connection to database server Aborted (core dumped)

Tom

This is an non-blocking method.

Ибраги́м

This is an non-blocking method.

Sorry, the issue is with auto result = sql->execSqlSync("SELECT * FROM log");

Tom

This means that it cannot be used immediately after creation.

Tom

It takes some time to create the connection to database.

Ибраги́м

Shit, u are right.

Tom

and if you use the Sync method of it, please use try-catch

Ибраги́м

std::this_thread::sleep_for(3s); try { auto result = sql->execSqlSync("SELECT * FROM log"); // Block until we get the result or catch the exception;

Ибраги́м

and if you use the Sync method of it, please use try-catch

Sure.

Tom

yes

Ибраги́м

U shall be judged for this!

Ибраги́м

It takes some time to create the connection to database.

Which means there should be a way to know when conn is done, maybe a callback since it's a non-blocking method.

Tom

almost all methods in drogon are non-blocking.

Tom

Yes, this is a good idea, but when DbClient is created at the beginning of the application and used throughout its lifecycle, the callback is not very necessary.

Ибраги́м

Yes, this is a good idea, but when DbClient is created at the beginning of the application and used throughout its lifecycle, the callback is not very necessary.

Or an bool connected() DbClient member function .

Ибраги́м

Yes, this is a good idea, but when DbClient is created at the beginning of the application and used throughout its lifecycle, the callback is not very necessary.

Oh, I get the last part.

Ибраги́м

But the interface is quite strange compared to http etc.

Tom

Thanks, I'll think about this.

Ибраги́м

Thanks, I'll think about this.

If I have time, I will help look into the lib more. It's been a while I've seen a quite usable C++ net lib like this with great performance and fast compilation times.

Thank you very much!

Glad u came today, have time for more question ? Still on db ?

Tom

I will try to be online in the future.

Use inline assembly

I'd like to write a function that stores the frame of the calling function, then "returns" from both the current and the calling function, so that I can later enter the "calling" function at the same position and load the stored frame onto the stack. That way I could easily create generator functions that I'd mainly use for coroutines. Is assembly the only way to implement that? I was hoping for a more portable solution.

Angelo

if the condition in the if statement is true it means it's egual to 0 ? I'm confused, If I call a function like strcmp(string a,string b) and use put it in an if statement, if the strings match means that function will return 0 and so it's true, but for the if a condition is true when it's unequal to 0, why it's confusing? So the proper way to do it is if(!strcmp(a,b))

unequal to 0 means not equal to 0

Angelo

yeah but, strcmp returns 0 when the strings matches but the if works contrary

Pavel

strcmp returns 0 for equal strings, yes? then if (strcmp(str1, str2)) {...} else {...} should go to the else block if str1 and str2 are equal.

Pavel

do you experience a different behavior?
