I'm trying to install packages via nimble, but it hangs at "Downloading https://github.com/whatever using git" and it never proceed past that.
Is that a known issue ?
$ nimble --verbose install polymorph

Prompt: No local packages.json found, download it from internet? [y/N]
Answer: y

Just tried it, works without problems for me on Windows 10:

Success: polymorph installed successfully.
I got really annoyed by this, so i decided to dig a bit more.
$ nimble install pixie --debug
Reading official package list
Downloading https://github.com/treeform/pixie using git
Cloning latest tagged version: 5.0.2
Executing git clone --recursive --depth 1 -b 5.0.2 https://github.com/treeform/pixie /var/folders/76/60fp513x38991r0s6cg_npcw0000gp/T/nimble_40295/githubcom_treeformpixie
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
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)
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;
}
So there is something fishy in the nim io internals.

Well you already are capable of reading Nim's fishy IO internals so please enlighten me and create a PR.
This also works for me:
proc system(cmd: cstring): int {.importc: "system".}
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"
system(cmd.cstring)
