I couldn't repeat on Vista Ultimate 64-bit with Sakila example database. Are you able to provide your SQL files?. Thanks in advance.

Alfredo Kojima
Do you have a python interpreter installed? If so, that may be a conflict with the WB shipped one, caused by a bug that has been fixed recently.

I could provide an SQL file, but import consistently fails on my system. So it won't be due to the content of the file to import (the error appears so fast it that I think the file hasn't even been opened). So it probably comes down to a system configuration setup that is not handled. Thus, your remark about Python versions seems closer to the problem. As I also use Hg Mercurial source control (that doesn't come with its own version of python), I indeed also have Python installed on my system as a standalone application. Looking at my list of installed programs I have even both Python 2.5.4 and 2.6.6 installed. Note: a former version of workbench (2.5.16) worked fine on my system. Only after upgrading to 5.2.29 and later to 5.2.33 and even 5.2.33b the error started appearing. But then, perhaps in between that same time I upgraded Mercurial and, as a requirement, the Python version. Some searching on the first error message (object has no attribute STARTF_USESHOWWINDOW) directed me to these link: http://web.archiveorange.com/archive/v/5H3d1ZrPVqSmi86w1StG that directed me to this link: http://svn.python.org/view/python/tags/r27/Lib/subprocess.py?r1=79064&r2=82504 Or this one: http://stackoverflow.com/questions/4703983/module-subprocess-has-no-attribute-startf-usesh... I don't know enough python to see if the solution given in the latter could be a workaround for me.

Please try the package from ftp://ftp.mysql.com/pub/mysql/download/gui-tools/mysql-workbench-gpl-snapshot-5.2.34.7605-... (just for testing, it's an early development build, so there's untested and unfinished things in it).

Thanks for your very fast response. Unfortunately however, I get an error on downloading the link (Error 324 (net::ERR_EMPTY_RESPONSE) on Chrome, 500 OOPS: vsf_sysutil_bind on firefox, and with fireftp I can't browse to the correct dir getting the same error as on firefox)
[28 Apr 2011 10:11]
Erwin Derksen
OK, today the download worked but the import still failed. Based on the article on Stackoverflow (http://stackoverflow.com/questions/4703983/module-subprocess-has-no-attribute-startf-usesh...) I changed the following in file wb_admin_export.py: added line 22: import _subprocess changed lines 127/128 (added the underscores): info.dwFlags |= _subprocess.STARTF_USESHOWWINDOW info.wShowWindow = _subprocess.SW_HIDE And now import works fine, both in the downloaded 5.2.34 and 5.2.33b. I leave it up to you to see: - if the "import _subprocess" will work fine on other (non Windows) systems (the other changed lines are only executed on Windows) - if _subprocess will be defined in other allowed Python versions.
[28 Apr 2011 10:20]
Erwin Derksen
Note: the constants (STARTF_USESHOWWIND and SW_HIDE) are also used in wba_monitor_be.py. You will probably have to apply the same changes over there.
[28 Apr 2011 12:26]
Alfredo Kojima
Hi Could you please add the following line in wb_admin_export.py, after the import statements at the top of the file and then send us its output, which should be printed to the Output window? print "subprocess module path:", subprocess.__file__
[28 Apr 2011 12:52]
Erwin Derksen
That was easier said than done, I finally found a file wb.log that seems to contain stdout output of wb, see below:. The answer thus is: C:\Program Files\Python26\Lib\subprocess.pyc 14:44:30 [ Info][ wbprivate]: WbContext::init 14:44:37 [ Info][ wbprivate]: Starting tunnel 14:44:55 [ Info][ grt.python]: subprocess module path: 14:44:55 [ Info][ grt.python]: 14:44:55 [ Info][ grt.python]: C:\Program Files\Python26\Lib\subprocess.pyc 14:44:55 [ Info][ grt.python]: 14:44:55 [ Info][ grt.python]: 14:44:55 Restoring D:\Projecten\data.mysql 14:44:55 [ Info][ grt.python]: 14:44:55 [ Info][ grt.python]: Running: mysql.exe --defaults-extra-file="c:\users\erwin\appdata\local\temp\tmpwicrse.cnf" --host=margrietslaptop --user=root --port=3306 --default-character-set=utf8 --comments < "D:\\Projecten\\data.mysql" 14:44:55 [ Info][ grt.python]:

Please open the scripting shell (in Scripting menu) and in the prompt type: import sys print sys.path import os print os.environment then paste the output here.

Thanks for the effort you put into this. I get the following output (I added line breaks after the comma's for readability)

If os.environment was meant to get the value PATH:

Sorry, was supposed to be print os.environ (Yes, I need the value of PATH, but I need the one that WB is seeing, so please repeat the test with os.environ) Was that output from the test binary? If not, can you try with it? With this extra information, it should be enough to fix the issue. The problem seems to be that your own installation of Python is not being ignored by WB, as it was supposed to be.

OK, I unzipped that test version again and ran the script in that version:

Wrong slashes in this sys.path part: D:\\Program Files\\MySQL\\MySQL Workbench 5.2 CE/python/site-packages'????
[28 Apr 2011 17:38]
Alfredo Kojima
The mixed slashes / in the path shouldn't matter. But now I'm confused, as nothing in your environment points to the other Python dir. What does import subprocess print dir(subprocess) print subprocess.__file__ show for you in the test binary?
[28 Apr 2011 18:40]
Erwin Derksen
I ran this script in the scripting shell (added some lines to discover if there are differences between the shell and the import process):
-------------------------------------------------------------------------------
# -*- coding: utf-8 -*-
# MySQL Workbench Python script
# <description>
# Written in MySQL Workbench 5.2.34

#import mforms
import subprocess
print dir(subprocess)
print subprocess.__file__
info = subprocess.STARTUPINFO()
info.dwFlags |= subprocess.STARTF_USESHOWWINDOW
info.wShowWindow = subprocess.SW_HIDE
With this as result:

To be sure, I added these lines to the import code and ran the import once again:

self.print_log_message("subprocess file: %s" % subprocess.__file__)
