when I execute this code, taking error "awk: line 19: syntax error at or near", I want to know how to locate where the error occurred, line 19 is comments, so line 19 is not the 19 line in code? and what can i do for this issue?

ANSWER

Answered 2022-Mar-23 at 12:50

There are a few adjustment you need to make:

don't increase i manually in the loop but use step value in range(start, end, step). The step value here would need to be 5.
You need to append the results to the list, otherwise you are just replacing the value over and over again and only the last value will be stored in the variables at the end of the for loop.
you probably want to strip the newlines \n (but this is optional) using rstrip("\n").
you probably also want to have all the possibilities for an answer in an array (but this is also optional). You can do that by using split("#") on the relevant string.

QUESTION

Is renaming a safe way of locking files?

Asked 2022-Jan-29 at 17:16

I'm in the process of rewriting a PHP app for node.js.

One of the components involves parsing a live webserver log, using the information then writing some of it back to the log.

I lock the file to avoid overwrites (with up to 100+ entries/second in production and parsing every hour or so, they do happen quite often without the lock) like this:

ANSWER

Answered 2022-Jan-29 at 06:12

Well, according to some nginx doc (see the "Log Rotation" section), nginx keeps the log file open so when you rename it, nginx just keeps writing to the same file descriptor it had which is now the renamed file. Until you signal it, it won't make a new file. So renaming the log file won't do anything to nginx. According to that, it will just keep writing to the renamed file.

So, I guess the answer to "Is renaming a safe way of locking files?" for nginx is "No". It doesn't lock anything.

flock -n creates/checks for a lock at the given /var/lock.. location

No, flock works on file descriptors.

/var/lock is a typical location for system administrators to put locks for global utilities. Like for example for package managers (pacman, apt-get etc.). You can use (ok, almost) any file anywhere with flock.

Let's say generally, flock is a property associated with a file referenced by a file descriptor. The number 100 is not significant, it has to be any open for writing file descriptor.

100>/var/lock/dobackup.lock redirects file descriptor 100 to file /var/lock/dobackup.lock. flock -n 100 applies flock on the file descriptor 100. When file descriptor 100 is closed (which happens when process terminates) then flock associated with that process is lifted automatically.

See Wikipedia for file descriptor, see man 2 flock and man 2 fcntl.

ok, looks like i found my solution here: https://gitlab.alpinelinux.org/alpine/aports/-/issues/12406

quote from Lyle Franklin:

I hit this error when trying to build a cross-platform ARM64 docker image from a AMD64 host. However, running docker run --rm --privileged linuxkit/binfmt:v0.8 or update-binfmts --enable prior to running the build seems to avoid the issue. My understanding Docker will try to use upstream QEMU if it is installed and registered with the kernel, otherwise Docker will fallback to using a built-in forked version of QEMU. The build error above only showed up for me with the forked QEMU.

So I will probably add docker run --rm --privileged linuxkit/binfmt:v0.8 && update-binfmts --enable to my pipeline file if I encounter the error again, for now running it once solved the issue.
