Ripgrep: -v switch sometimes gives wrong results

[stej]

I still don't have some reliable repro, but I'll try at least..

I have this search:
rg 30193293 -g 2017-01-09* | rg -v "Logging inputStream from mail service|notifications received"
When I run it only on several (about 10) files, it returns correct results. But when I run it on a lot of files (log files for one month), then it gives weird results. rg 30193293 -g 2017-01-09* -c returns results from 6 files, but when I add the pipe and -v, it returns results from files where string "30193293" is not contained. Any idea, how to make a reliable repro, if this is a bug?

Btw. I'm on windows.

From your description, it sounds like you're not saying that -v is wrong, but that the initial search is wrong. Namely, if you're seeing results without the string 30193293, then doesn't that mean the first rg command reported a line as a match that wasn't a match? If so, that's where I'd start with a repro.

For example, compare the output of your command:

$ rg 30193293 -g 2017-01-09* | rg -v "Logging inputStream from mail service|notifications received"

with this

$ rg 30193293 -g 2017-01-09* | grep -v "Logging inputStream from mail service|notifications received"

and this

$ grep 30193293 --include 2017-01-09* | grep -v "Logging inputStream from mail service|notifications received"

I didn't write it clearly. I think there is no problem with the first run of rg 30193293 that returns correct results. It seems that combination of pipe and -v option doesn't work in some cases.

I tried

grep.exe 30193293 2017-01-09* | grep.exe -v "Logging inputStream from mail service|notifications received" > %~dp0grep-grep.out.txt

rg 30193293 -g 2017-01-09* | grep.exe -v "Logging inputStream from mail service|notifications received" > %~dp0rg-grep.out.txt

rg 30193293 -g 2017-01-09* | rg -v "Logging inputStream from mail service|notifications received" > %~dp0rg-rg.out.txt

and the first 2 commands give me the same results (after some sorting).

I killed the the last command when rg-rg.out.txt had 10GB size. And indeed I inspected the output file rg-rg.out.txt and it looks like the -v ignores the input from pipe and runs the search in the current directory for all the files. There was no line that would match pattern "Logging inputStream from mail service|notifications received".

What version are you running? Not so long ago, piping any output to rg was broken and it would behave exactly like that.

[stej]

Yes, you are right. I had 2 versions on my machine. One on the path, the other one diretly in the directory hidden behind a lot of files..
Versions 0.3.2 vs. 0.2.6.

Problem solved. Thank you for your time.
