March 11, 2019 at 15:24A selection of utilities for a programmer under Linux
I think every programmer has a set of favorite utilities, tricks and knowledge. He even uses some in his work. Most likely, they differ among different programmers. So it's time to share. Today I will talk about my selection of what is probably not known as widely as it deserves. It will be mainly about the GNU / Linux platform.
PMD & CPD
First, a little cross-platform. There is such a utility - PMD , probably well known to Java programmers. This is a static analyzer that supports several (not very many) languages, which is not surprising - writing meaningful analysis rules is hardly a simple task. But this utility also has a second part - Copy-Paste Detector (CPD). Its work requires significantly less “understanding” of the source text, so it is logical that it processes significantly more languages.
So, there is an opinion that an open source project is when you need to write code not just to work, but also to prevent other programmers from laughing. In the case of large projects, this is probably the case, but copy-paste is not so noticeable. To the maintainers, alas, too. And then one day, having received from the developers of one program a comment that “If here and here these three lines are put into an auxiliary method, then probably in the other twenty places as well,” I decided to evaluate the extent of what was happening. On the one hand, repeating a pattern of three lines can look fearless. On the other hand, it clearly makes some sense, and it will be easier for newcomer contributors if the meaning is clearly reflected in the name of the method.
Hidden text
We discuss someone’s code at work:
xxx: So you imagine, he has a 15-line code fragment there repeated 37 times. If you put it into a function, you can save half a hundred lines!
yyy: it's a refrain.
Without thinking twice, I launched CPD on this C ++ project, expecting to see a repetition list of this three-line pattern. I just didn’t encounter it (it did not exceed the default threshold for the number of tokens per repeat), but I saw many cases like repeating an identical method of 50 lines in two different descendants of the same class.
It is unlikely that the main developer consciously copied such a piece - apparently, something else happened: someone once added this method in one of the classes, and in another pull request after a lot of time someone, without thinking twice, copied it. It is logical that this code was no worse than what is already in the repository (ha ha), so it was accepted.
Mozilla rr
Have you ever experienced that, while debugging a program, you reproduce a bug for a long time, and then one wrong move - Step over instead of Step into - and that’s it, pichalka, replay everything for another ten minutes!
With the Mozilla record-replay framework, everything is somewhat different: “run tests at breakfast, debug when you get back”they said. This tool does not try to record state changes after each instruction (they say gdb has this mode ...), instead, it simulates the execution of a program ... using the program itself. The logic is this: in general, the execution of the process is completely determined, with the exception of certain “disturbances”:
- the kernel can produce different data in response to the same system call - just write down all the answers (you need to know each system call “in person” with all the structures used)
- the RDTSC instruction always generates something new - fortunately, it can be made privileged and manually set values for each trap
- On another computer, CPUID will also give something else - on fresh processors it can also be made privileged
- multithreading and multiprocessing - and here it is necessary to discuss in more detail
- maybe I forgot something else, but the bottom line is that the list is quite finite
As far as I understand, it works somehow like this: all threads of the entire process tree being written are crammed into one thread, reducing the “multithreading description” to the number of instructions between context switches. One disadvantage follows from this. Once the FSF swore at the monopoly of the “Wintel architecture”, and so: rr will run only on “Lintel”, that is, only on Linux, and only on fresh (Nehalem and higher) Intel processors that have fairly stable performance counters. There were attempts to launch on Ryzen, something was even possible, but there are flaws. At the expense of other OS cores - I do not know.
With rr, you first run the program normally, click on the buttons / enter commands, all this with braking about one and a half times, or even less. And then you type rr replay, and the program starts to run “in virtual reality”, in which everything happens exactly the same as when recording. Naturally, you will not see windows and all that - stdout and stderr are saved - and thanks for that. Instead, you'll see gdb (they say graphical debuggers like QtCreator and CLion are also supported, but I haven't tried it yet). But if you accidentally entered n( next), and then realized that you didn’t have to do this, you can say rn( reverse-next) or put a breakpoint and say rc( reverse-continue). As far as I understand,reverse-commands are regularly present in gdb, just for obvious reasons, rarely which backend is able to support this.
A special chic, in my opinion, is to look for the cause of the malfunction in this way: here you clicked c, and the program stopped at assertion. Having studied the state of the variables with the help, printyou realized which variable has an incorrect value. But who exposed her? You just say watch -l <переменная>(forever confusing syntax, I hope not this time) , setting the hardware breakpoint to write to memory, and then say rc( reverse-continue) - soap, wash, repeat ... Just remember to delete the old hardware watchpoints from memory, because there are not so many of them.
But can it be the same, but with mother-of-pearl buttons?
First, what if you want to debug the operating system in a virtual machine? I myself have not encountered this yet, but, they say, QEMU has gdbserver and in general. And if you want the same as in rr, but for QEMU? The documentation mentions the built-in record / replay :
Record / replay functions are used for the reverse execution and deterministic replay of qemu execution. Determinitsic replay is used to record volatile system execution once and replay it for multiple times for the sake of analysis, debugging, logging, etc. This implementation of deterministic replay can be used for deterministic and reverse debugging of guest code through a gdb remote interface.
By the way, the first version of patches was developed, according to the same page, by the Institute for System Programming of the Russian Academy of Sciences.
Well, and if you want to debug one process, but in Java? There is a HotSpot unwinder for GDB. On a similar request, there is such a page where it is said that it is expertly poking around in the JVM address space, providing btinformation for the team . I discovered this by accident, connecting to the JVM process and requesting backtrace. Alas, when preparing this article on Ubuntu 18.10, unwinder steadily crashed gdb, but the tool can, when it is repaired, probably help in some ways in the mode rr.
He sees an eye, but a tooth is numb
Once, when debugging, I encountered a No space left on device error. It would seem a common thing, my place is constantly running out due to compilation artifacts. But there was something strange - it df -hshowed several free gigabytes on each partition, and, as far as I know, this is already taking into account the space reserved for the root user. A quick googling led me to advice to look at the output df -i, and indeed, there were no free inodes on the right section, that is, the files were small, but a lot .
Trace this and that
I think many people know about strace, and if not, it is often a very useful utility that shows what system calls a process or a whole tree of processes makes.

Probably fewer people know about ltrace- a similar tool for analyzing calls between dynamic objects (program and libraries). Alas, it seems that the development is ltraceabandoned, which would seem strange, given that the tool is useful and in general should be managed by the same development team that the loader is sawing from libc. In such cases, it is customary to say “You won’t believe ...” :) It turns out that glibcthere is a tool in the latest versions sotruss. It has less configurability, however, but it’s also relevant glibc. There is a fly in the ointment: neither ltrace, norsotrussthey do not decode call parameters, which is not surprising - there is no exhaustive list of what calls they should decode, third-party meta-information is already needed here. Maybe it can be somehow enclosed, but, frankly, I didn’t really have to use library tracing. However, I think it is useful to know about such tools.

+++ exited with 0 +++Riddle: find timeor gettimeofday.
Solution: reboot with the kernel option vdso=0and search again.
The fact is that some calls, such as gettimeofday, are considered to be often called and at the same time do not require a full switch to the kernel. Therefore, at the top of the user address space, the kernel attaches the vDSO pseudo-library , which provides a quick interface to some system calls. By the way, it is written there that seccompthey, most likely, will not see them either.
