#Goland free free
You can use memory arenas in functions that allocate a large number of objects, process them for a while, and then free all of the objects at the end.
Memory arenas allow to allocate objects from a contiguous region of memory and free them all at once with minimal memory management or garbage collection overhead. In addition, the memory usage is often larger than necessary, because Go runtime delays garbage collection as long as possible to free more memory in a single run. However, large Go programs have to spend a significant amount of CPU time doing garbage collection. Such automatic memory management simplifies the writing of Go applications and ensures memory safety. Go runtime achieves that by periodically running a garbage-collection algorithm that frees unreachable objects. Go is a garbage-collected language and so it can automatically free allocated objects for you. You can use memory arenas to improve performance by reducing the number of allocations and deallocations that need to occur during runtime. ldflags "-X \"main.subversion=\"`date -u +.%Y%m%d.Go 1.20 release added a new experimental arena package that provides memory arenas. I tried similar alternatives to no avail: -ldflags "-X 'main.subversion=$(date -u +.%Y%m%d.%H%M%S)'" While obviously I'd expect to be something like While this does not raise an error, it also does not produce the expected behaviour: the subversion variable is literally assigned the string: `date -u +.%Y%m%d.%H%M%S` Jetbrains suggested to use this syntax under Go tool arguments: -ldflags "-X 'main.subversion=`date -u +.%Y%m%d.%H%M%S`'" One more option would seem to create a makefile, but have been looking into this for hours now so I'll pause before looking into this option, which may be overly complex for what I need to do #gosetupĪm alternatively exploring using GOFLAGS="-ldflags=-X main.subversion=$(date -u +.%Y%m%d.%H%M%S)"īut am bumping into a similar problem so far
usr/local/opt/go/libexec/bin/go build -ldflags "-X main.subversion=$(date -u +.%Y%m%d.%H%M%S)" -o /Users/./Downloads/ta_mac. Usage: go build Īlthough if I do run manually the same command, it succeeds and the app produces the expected behavioud with the correct value for the variable subversion. Invalid value "\"-X" for flag -ldflags: missing = in =
In the run tab I see: GOROOT=/usr/local/opt/go/libexec #gosetup It seems to be having problems escaping the double quotes, but can't figure out what I am doing wrong. Go build -ldflags "-X main.subversion=`date -u +.%Y%m%d.%H%M%S`"īut goland ide fails when adding the same flags to my go build configuration > Go tool arguments: -ldflags "-X main.subversion=`date -u +.%Y%m%d.%H%M%S`"
