在加载ssh-agent / git时，Powershell在启动时需要很长时间才能加载

Question

I have Powershell set to use posh-git through Git for Windows. In my profile file I have this:

# If Posh-Git environment is defined, load it.
. (Resolve-Path "$env:LOCALAPPDATA\GitHub\shell.ps1")
. $env:github_posh_git\profile.example.ps1

Every time I open Powershell it requests the passphrase for my id_rsa key. That's fine but it takes longer and longer to actually display the request. When I first set it up this way it prompted for the pass quite fast but the loading times increased over time.

Any suggestions? I don't even know what to begin with in looking into this.

Answer 1

The problem is indeed slow setting of user environment variables. I recently merged a change that uses a temp file instead.

The latest GH4W (1.0.48.0) includes this change.

I traced this problem down to this: https://superuser.com/questions/565771/setting-user-environment-variables-is-very-slow

Since chrome have many processes that takes time to response, I simply closed down Chrome in my profile.ps1 like this.

$agent = Get-Process -Name ssh-agent -ErrorAction SilentlyContinue
$chrome = Get-Process -Name chrome -ErrorAction SilentlyContinue
$chromepath = $null
if(!$agent -and $chrome){
    Write-Host "Chrome is open, press any key to close"
    $host.UI.RawUI.ReadKey() | out-null
    $chromepath = $chrome[0].Path
    $chrome | Stop-Process
}
Start-SshAgent -Quiet

if($chromepath){
     Start-Process $chromepath
}

I had a similar problem (without passphrase requests). Reinstalling helped. It is the advice given here :

Eiter way, today I completely removed all traces of posh-git (including the entries in Microsoft.PowerShell_profile.ps1) and cloned it from source. This solved the problem for me!
