Defect another world

Chapter 186 Three days and three nights
In fact, Liu Gang's operation gave him a strong inspiration.

He has made it very clear what Liu Gang is doing here alone.

Liu Gang is looking for and deleting all unnecessary debugging information, and setting off the function of generating these debugging information from the configuration file.

Some debugging information cannot be configured and disabled with configuration files, and is hard-coded in the code.He had to carefully recompile and update parts of the program.

This job is not easy, and without the cooperation of the test team, the entire system may be blown up if you are not careful.

But it gave him inspiration.

Each system of Mantis has countless debugging information in it.Even after delivery, a lot of debugging information has not been deleted.

As a start-up team, this is actually understandable.

But in the case of negentropy, this may cause a little problem.

Because the Goddess's Sleeping Coffin only accepts "me only" data.If the original data is not cleaned, it will be rejected.

But what if the original data is not cleared, but the debugging information generated during the operation of the entire system is not cleared?
If there is a possibility that these debugging information can be converted back to the original data, it means that the original data has not been cleaned.

If this is the correct explanation for the loss of negentropy, then it means that the negentropy is not actually lost, but just hidden in the debug information?

This seems to contradict the fact that the system has been able to successfully input negative entropy into the Coffin of Sleep and obtain data back for many years.

But the program does not necessarily run the same every time.Any bad luck, a difference in a certain environment may lead to different results.

For example, the output of debugging information is not turned on in a certain run, but it will be turned on in the next run?
Even a beam of ancient cosmic rays from hundreds of millions of light-years away happened to hit a certain bit in the memory unit.

Cause 0 to become 1, achieve incredible supernatural miracle?

Why did the task force investigate for so long, but did not find this problem?

Perhaps the answer is very simple. The external experts sent by the special task force do not know that the problem lies in the mantis software, and they do not know the internal problems of the mantis software.

Even people from Mantis Software may not know what is in their system, except for the person who actually wrote the code.

If Liu Gang wrote the code by himself, he probably knew it.But will he really seriously investigate and expose the problems he created?
What is he here to clear the debug information and close the interface?
Could it be that he discovered clues during the investigation, and he realized that he couldn't handle this cauldron related to the fate of the country, so he simply eliminated the clues?
Of course, his operational behavior itself cannot be concealed.But the behavior can be interpreted as a simple optimization upgrade system.

And after doing this, no one may associate the loss of negentropy with redundant debugging information in the future.

Why do you want to do this?

Compared with the century-old foundation of the country, the personal gains and losses, honor and disgrace, are you not sure which is more important?
If it were Meng Fei, even if the bug he wrote led to the destruction of the earth, he would obediently admit it and take the blame.

According to the jurisprudence of various countries in the world, no matter how serious the loss caused by the programmer's mistake, as long as it cannot be proved that the supervisor is malicious, the programmer will not be allowed to compensate.

Besides, this is not a BUG.This is at best a misunderstanding caused by an operational anomaly.

This really has a serious blow to the company's reputation.But judging from the close relationship between Luo An and the high-level people, it is not impossible to bear it.

In fact, software security companies are no different from military companies like Lynx Group, they are the shield of the country.

The state cannot allow these companies to be destroyed by accidental failures, leaving their fate to foreigners.

Most importantly, the negative entropy is not lost, is it?
Meng Fei felt that there was no need for him to think so much, and he was not interested in thinking about these issues that only high-level officials need to consider.

He has only one thought now.

He wants to confirm his guess and find the lost negative entropy in the vast amount of debugging information!

As long as the negative entropy is not actually lost, Mantis Software will not suffer any loss, nor will Qingmang Republic.

It's not easy.It is especially difficult because this cannot be solved by the strongest BUG system or any system.Because this is not a BUG.

A lot of service programs are still running, and you can't stop them and slowly disassemble them.Accidents may happen to the whole country if it is moved casually.

He created a new virtual machine using idle resources in the server.A virtual machine can largely mimic a real operating environment.

At the same time, anything he does here will not affect the operation of external programs in most cases.

Then he copied the software on the real server into the virtual environment one by one, trying to simulate the real environment to run.

From the start to the completion of this step alone, five hours passed quietly.

From about [-]:[-] p.m. to [-]:[-] p.m., Meng Fei clenched his fist and shouted: "Woc! Let's run!"

Suzaku stared from the side like a sculpture.

"...I mean that my virtual environment is up and running, and I can successfully complete the process of extracting and decrypting negative entropy data.

"The problem now is that the debugging information I want is still there. Many components have been deleted by Liu Gang.

"Fortunately, he didn't use any thorough measures, and I recovered a lot."

Meng Fei muttered and looked at Suzaku next to him.

"It's okay, you continue."

she says.

"okay!"

Meng Fei, who was a little tired at first, suddenly felt full of energy and blood, and tapped the keyboard again.

What he has to do is to try to decrypt a small piece of encrypted negative entropy data, and try countless combinations of debugging switches in those codes to see if he can get a complete debugging log that can restore the decrypted data.

Failed once?

Just restart the virtual machine and try again.

Failed again?

carry on.

Anyway, it is a virtual machine, even if you press the power button [-] times, it will not damage the hard disk or anything.Because its hard disk is virtual.

The scary thing about software systems is that, even with a few simple combinations of conditions, the number of possible paths combined can easily exceed the number of all atoms in the universe.

So really exhausting all possible tests is simply not possible.

But a real veteran will eliminate all irrelevant things among the countless clues and find the real relevant factors.

The rest is ruled out only by violent attempts.

Suzaku just looked at him like a lunatic, modifying the code, compiling, restarting the system, and checking the logs.

Then modify the code again, compile, restart...

Infinite loop.

There are also some intervals between drinking water, eating, shitting and sleeping on the stomach.

Ansheng is responsible for delivering water and meals.

She is responsible for water and food.

After about thousands of restarts, she suddenly felt her palm tighten and was held by Meng Fei.

"This guy actually started to move his hands and feet..."

she thought to herself.

At this time, Meng Fei's eyes were deep and sincere.

"Run out.

"Sure enough, there is a problem with the debug log of the decryption system.

"Next, it's up to me to recover all the negative entropy data."

"Do you know what day it is today?"

Suzaku smiled softly.

"Oh? Didn't notice..."

"It's 2:10 a.m. on February 1.

"We have been here for three days and three nights."

"Crap!"

Meng Fei suddenly screamed.

"Isn't Valentine's Day already over?"
