I got really annoyed by this, so i decided to dig a bit more.
$ nimble install pixie --debug

this still hangs.
After debugging i discovered that nimble hangs in `io.nim` procedure `readLine`
of the `File` type:
var fgetsSuccess: bool
while true:
# fixes #9634; this pattern may need to be abstracted as a template
if reused;
# likely other io procs need this for correctness.
fgetsSuccess = c_fgets(cast[cstring](addr line[pos]), sp.cint, f) !=
nil
if fgetsSuccess: break
when not defined(nimscript):
if errno == EINTR:
errno = 0
c_clearerr(f)
continue
checkErr(f)
break
Run
It's basically hanging in fgets and it never exits the while true. breaking in
the debugger, it always breaks into the fgets.
Then decided to try the same command nimble is executing in a nim program:
import std/osproc
when isMainModule:
let cmd = "git clone --config core.autocrlf=false --recursive --depth 1
-b 5.0.2 " &
"https://github.com/treeform/pixie " &
"/var/folders/76/60fp513x38991r0s6cg_npcw0000gp/T/nimble_43913/githubcom_treeformpixie"
execCmdEx(cmd)
Run
and it still hangs for me at the execCmdEx (execProcess and friends produce the
same issue).
But then i tried a simple stupid C program, and this magically works.
#include <stdio.h>
#include <stdlib.h>
int main()
{
system("git clone --config core.autocrlf=false --recursive --depth 1 -b
5.0.2 "
"https://github.com/treeform/pixie "
"/var/folders/76/60fp513x38991r0s6cg_npcw0000gp/T/nimble_43913/githubcom_treeformpixie");
return 0;
}
Run
So there is something fishy in the nim io internals.
