Nice to see Vyukov's MPMC queue mentioned. It's pretty neat. I have used a C implementation[1] of this in a small personal project.

I am in a similar boat where I never completed my degree. I am from Asia. As far as I know even if a job does not require a degree, lots of countries do require Bachelor's degree to get a work visa, for example, for USA it's either bachelor's or 3/4 years of experience per university year I think. I would appreciate if you could share your story of how you moved to America.

Sorry. You are right. I can't edit the URL now and can't delete it either.

Hi. I haven't compared it with rsync as rsync has a lot more features than dsync. dsync only works locally which is what I needed and decided to implement myself.

Hey. Thanks for the input. I have heard of rsync but did not try it out because I wanted to implement something simple on my own. And about the benchmark, I think comparing with cp makes sense as when targeting an empty directory it is really just measuring what time it takes to "copy". I guess it could make sense to do "sync" benchmark too but I really just measured the copy performance to be honest.

Show HN: Dsync: a tool to sync source directories/files to a target directory

Hello HN. I worked on this small project recently called dsync. I have a few directories where I keep adding stuff and I need to sync them to an external drive from time to time. In the spirit of "write your own tools", I wrote my own. The tool itself is really simple. It tries to sync source directories or files to a destination directory based on size and modification time, basically copying the source files if they don't match.

dsync can use multiple threads (specified via an option). It uses a bounded multi-producer multi-consumer queue (C implementation of Dmitry Vyukov's bounded MPMC queue using gcc atomic builtins). The main thread traverses the given sources and adds the files to the queue. Other threads dequeue entries from the queue and do the sync/copy work concurrently.

dsync performs well with multiple threads compared to GNU cp when copying directories with a lot of small files such as the linux kernel repository. More details are in the README.
