Dir.glob very long on pc

Developers Ruby API
#1

Hi all,

On my Sketchup extension I use
Dir.glob(File.join(folder,"/**/*.skp"))
On my mac, its take less than 1 second to list all Sketchup files.
One of my dev use a pc and with the same library, it’s take 30 secondes to list all the file.

We try alternative to Dir.glob like Find.find, IO.popen(“find . -name ‘#{path}’”).each { |path| parse(path.chomp) } but nothing fast as Dir.glob on mac.

Do you have any advice, walk-around, tips, tricks ?

#2

Is the folder path a local or network path ?

#3

Is the folder path a local or network path ?

local in both case ( c/: for windows)

#4

Is this any faster ?

Dir.chdir(folder) {
  Dir.glob("/**/*.skp")
}

Are you running a SketchUp Windows edition under bootstrap on Mac ? ie, virtually ?

This seem to be a latency issue which can vary per hardware (disk caching, etc.) or AV scanning.

Picking a nit, but bootstrap isn’t a virtual machine, it literally boots Windows on your Mac hardware.

I try the followinf code, and still very long (same time):

Dir.chdir(folder) {
Dir.glob("/**/*.skp")
}

[/quote]

itsn’t bootrap. its a normal windows X on a normal pc

#8

Literally c/:.Are you searching the whole C drive for sketchup files?

#9

Noooooo :smiley_cat:. iI use it on sub folder donwload from we transfer. The same wetranfer on mac and pc

My solution

  def self.glob(folder)
  	if Sketchup.platform == :platform_win
  		active_folder = File.dirname(Sketchup.active_model.path)
  		active_folder = Dir.pwd if active_folder == "" || active_folder == "."
  		tmp_file_path = File.join(active_folder,"tmp.txt")
  		`dir *.skp /b /s > #{tmp_file_path} `
  		tmp_file = File.open(tmp_file_path)
  		all_files = tmp_file.readlines.map(&:chomp)
  		tmp_file.close
  		File.delete(tmp_file_path)
  		return all_files&.compact
  	else
  		return Dir.glob(File.join(folder,"/**/*.skp")).sort
  	end
  end

On Windows, consider not using a glob string starting with a ‘/’, as it will always search the current drive.

If there is no open model, Sketchup.active_model.path is empty. The followings should return the model location from the preferences dialog:

Only tested on recent SU versions, and US-English…

# Windows Only - model_path is the directory listed in:
# Window - Preferences - Files - Models

require 'json'

pref_file = [
  ENV['LOCALAPPDATA'].tr("\\","/"),
  "SketchUp",
  "SketchUp 20#{Sketchup.version[0..1]}",
  "SketchUp",
  "PrivatePreferences.json"
]

info = JSON.parse(File.read File.join(*pref_file), mode:'rb:UTF-8')
root = info.keys.first
model_path = info[root]["File Locations"]["Models"].tr("\\","/")
puts model_path

Thx! @MSP_Greg . I made correction after posting

  def self.glob(folder)
  	if Sketchup.platform == :platform_win
  		active_folder = File.dirname(Sketchup.active_model.path)
  		active_folder = Dir.pwd if active_folder == "" || active_folder == "."
  		tmp_file_path = File.join(active_folder,"tmp.txt")
  		`dir #{folder}/*.skp /b /s > #{tmp_file_path} `
  		tmp_file = File.open(tmp_file_path)
  		all_files = tmp_file.readlines.map(&:chomp)
  		tmp_file.close
  		File.delete(tmp_file_path)
  		return all_files&.compact
  	else
  		return Dir.glob(File.join(folder,"/**/*.skp")).sort
  	end
  end

Windows’ filesystem is generally slower than Unix based systems.

thx @tt_su for your answer. The customer was pointing on network, it was one of the reason of the extra latency (in addition to windows system)
