Ripgrep: High CPU usage when piping into less?
This is a weird behaviour, and may not be ripgrep's fault, but I thought I'd mention it in case.
I piped rg into less with rg cmd | less and looked at the first page of results, left them there and continued working. After a while I noticed that my CPU usage was high and rg was using 200% of my 400% CPU's available. If I run the command without less and time it, it takes around 0.5 seconds, but with less, the CPU sits at 200% continually.
If I type G then less goes to the end of the window and the rg process exits.

That's... strange. I kind of wonder whether it's related to #200, but I don't think it is.
I can't actually reproduce this either. If I run rg PM_SUSPEND | less in a checkout of https://github.com/BurntSushi/linux, then it seems to work fine. No CPU pegging.
What version of ripgrep are you running? OS? Shell?

I'm on macOS 10.12.1, using ripgrep 0.3.1 and fish, version 2.4.0. I can also reproduce this in bash 3.2.57.

@danielcompton Can you try this? (So we're searching the exact same data.)
$ git clone --depth 1 git://github.com/BurntSushi/linux
$ cd linux
$ rg PM_SUSPEND | less
Interestingly, the behaviour doesn't show up on your linux example. I was able to create a minimal example at https://gist.github.com/danielcompton/cc667b4904609de88c9008f60e11564c. Having those two files in a directory is all that is needed to reproduce it. Removing either one stops reproduction, though I suspect that may just be due to terminal window size.
EDIT: actually you can reproduce it if you just copy the encore.js.map file twice in the same directory.
The sourcemap file is extremely long (146k characters) and was presumably all being passed to less? This may be the issue?

Hmm, I still can't produce on either Mac or Linux. Not sure what's going on. I could maybe see if less was pegging your CPU (which happens to me if I page through it quickly), but the fact that rg is pegging your CPU is very strange.

@danielcompton Do other search tools exhibit this behavior? e.g., grep -r cmd | less
BurntSushi
on 1 Dec 2016
grep -r cmd ./ | less doesn't exhibit that behaviour.

$ pwd
/private/tmp/taoensso
$ ls
encore.js.map encore.js.map copy
$ rg cmd | less
# hangs ...
So I'm not quite sure how to move forward on this one. I can't reproduce it so I don't know how to fix it, and I'm not quite sure what debugging steps I would try next. If you're interested in getting into the nitty gritty, then I can think of a few things we can try:
- While
rgis hanging inless, find itspidand runstrace -p PID. - Does Mac have
perf? I'm guessing not. This would be useful because you could run something likeperf top -p PIDto see exactly what the process is actually doing.

I ran rg cmd | less in one shell and dtrace -p PID on the other and saw:

@danielcompton Thanks! I'm not quite sure what to make of that, but I'll noodle on it.

^C
You can ignore the dtrace: error on enabled probe ID 2134 lines, as that is just from macOS System Integrity Protection.

I can also reproduce this issue on Windows using more.com (as well as on Windows in a bash environment with less): > rg -i "<elided pattern>" | more.com.
One thing I noticed is that for small outputs it looks like rg can write all of it's output to less' buffer and exit. If the full output is too large rg seems to spin waiting for less to allocate a larger buffer. If you run to the end of the output and leave less running rg will exit and of course CPU usage drops off.
EDIT: Could it also be very long lines in the output? Both @danielcompton's gist and my private files have a lot of output on a single line.

Ah yes, forgot to mention I can reproduce this with more as well.

It turns out that "noodling" on this problem was exactly what was needed.
I ended up figuring out how to produce this. Basically, it happens whenever you:
- Pipe the output of ripgrep into a pager (or otherwise cause writes to
stdoutto block). - The number of directories to search is less than the number of threads ripgrep uses.
The issue here is that when one thread blocks on writing to stdout and there is no more work to be done, then the rest of the worker threads will spin on the multi-producer multi-consumer queue and therefore burn the CPU. (We don't use a blocking queue because we don't really know when directory traversal is finished.) I fixed this by inserting a very short sleep whenever a worker can't get work from the queue. This still pegs the CPU a bit, but it is much much less than before.
This also caused me to realized another shortcoming of the existing iterator. It was running searches for all direct children of a directory in the same thread. So if you ran ripgrep on a single directory with lots of files, you wouldn't get any parallelism! Owch.

Thanks so much for reporting this and digging into it! It was a tricky one!

Is there a build I can verify this against?

@danielcompton No, you'd have to compile from source. I plan to make a release soon though!
