Re: pp --clean does not seem to work (it does)

pp --clean does not seem to work ... no proof ...

You're confused, --clean works

when pp is creating an executable , it putts stuff into temp, this is what you're confusing for --clean not doing its job

$ rm -rf goner-temp

$ md goner-temp

$ set TEMP=goner-temp

$ set TMP=goner-temp

$ findrule goner-temp |wc --lines
1

$ pp --clean coy.pl

$ findrule goner-temp |wc --lines
109

Running the executable doesn't increase the number of files in temp, this means --clean is working

$ a.exe 1>NUL 2>NUL

$ findrule goner-temp |wc --lines
109
[download]

Emptying temp, and running the executable shows no files in temp

$ rm -rf goner-temp

$ md goner-temp

$ findrule goner-temp |wc --lines
1

$ a.exe 1>NUL 2>NUL

$ findrule goner-temp |wc --lines
2
[download]

Without --clean option the number of files doubles after running the executable

$ rm -rf goner-temp

$ md goner-temp

$ pp coy.pl

$ findrule goner-temp |wc --lines
109

$ a.exe 1>Nul 2>NUL

$ findrule goner-temp |wc --lines
220

--clean worked as designed, its working

Could it be that it works on windows and is broken on linux? Not likely -- now you know how to check

Re^2: pp --clean does not seem to work (it does) by hellosarathy (Novice) on Dec 14, 2015 at 09:03 UTC
Thanks Monks, I just ran few tests and realised that --clean works on 'normal' conditions. The temp-xxx is cleaned after normal exit. However, if the script crashed or killed for whatsoever reason, the temp-xxx contents are retained and not cleaned up. So probably have to deal that separately, like, to clean up explicitly in an END block or so...	[reply]

I just tried both a die() and a divide by zero in my test script and both times the contents of Temp\par-123... were cleared out. I'm testing on Windows. How are you killing the process?	[reply]

How are you killing the process? On unix systems, `kill -9` (i.e. sending `SIGKILL`) can not be caught, the process is terminated without a chance to save any data or to clean up. See also signal(7) and POSIX. Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply] [d/l] [select]
