WindowsError: (5, 'Access is denied')

Severity: blocker Keywords: directory,
Cc: Trac Release: 0.12

Description

How to Reproduce

While doing a GET operation on /browser/app/application/core, Trac issued an internal error.

I installed git+trac on my windows recently. The installation was finished and I can integrate git and trac and can be viewed in browser. But I have problem when I browse the resource via browser. I am developing web application using codeigniter. When I browse the root directory, it can be viewed by browser. But, when I tried to browser the child directory, the browser give me an error: WindowsError?: [Error 5] Access is denied. I don't know its error came from git, trac, or windows itself. Then I try to search on internet and also from trac forum at google and I can't find anything useful. I need any help from you or any information that be able to solve my problem. Thanks anyway.

Hi, sorry for the delay. Are you sure you sure this bug is filed against the right plugin. BrowserSvnOperationsPlugin the deals with Subversion. Your description and traceback suggest you're having a problem with GitPlugin

I was also having the same issue. It seems that calling p[0].terminate() (on lines 744 and 760 of PyGIT.py) will fail with the access is denied message on Windows (I'm using Windows XP and Python 2.7.2) if the process has already completed (i.e. is no longer running).

An easy, but possibly error-prone, fix which solved the problem for me would be to poll the sub-process to see if it's alive before trying to terminating it: 

if p[0].poll() is None:
    p[0].terminate()

A possibly more robust solution would be to catch the exception and ignore it: 

try:
    p[0].terminate()
except WindowsError:
    pass

Thanks Greg! this fixed the issue.

#!python try: p[0].terminate() except WindowsError?: pass

Greg's fix also worked for me. For anyone who is unable to find PyGIT.py, it is most likely part of the tracgit egg file. Egg files are just renamed zip files, so you can just change it to a zip, open it, edit the file and rezip it/re-egg it.

I would recommend making a backup of the original before mucking around with it.

  • priority changed from normal to highest.
  • severity changed from normal to blocker.

I did the change, but now I'm receiving this error: ZipImportError?: bad local file header in C:\\Python26\\lib\\site-packages\\tracgit-0.12.0.5dev-py2.6.egg

Anyone here can help me?
