[Errno 13] Permission denied_hotcopy_utility

[Balaji]

Hi Guys,

This is Balaji. I have recently installed Trac version 0.11.5 using
Apache + mod_python method . Installation and configuration of
database and users went fine without any trouble.

I am trying to make use of hotcopy utility inorder to get the backup
of the multi-project environment D:\proj\trac\ and D:\proj\trac1. The
hotcopy is done properly but i am gettting the error messages like
below,

C:\Documents and Settings\Administrator>d:\Python24\Scripts\trac-
admin.exe D:\proj\trac hotcopy D:\backup\trac-proj
Hotcopying D:\proj\trac to D:\backup\trac-proj...
The following errors happened while copying the environment:
[Errno 13] Permission denied: 'D:\\backup\\trac-proj\\attachments':
'D:\proj\trac\attachments'
[Errno 13] Permission denied: 'D:\\backup\\ trac-proj \\conf': 'D:

[Errno 13] Permission denied: 'D:\\backup\\ trac-proj \\db': 'D:\proj
\trac\db'
[Errno 13] Permission denied: 'D:\\backup\\ trac-proj \\htdocs': 'D:

[Errno 13] Permission denied: 'D:\\backup\\ trac-proj \\log': 'D:

'D:\proj\trac\templates'
[Errno 13] Permission denied: 'D:\\backup\\ trac-proj ': 'D:\proj
\trac'Hotcopy done.


Could any one guide me to correct the above error inorder get the hot
copy backup done successfully.

I am guessing you are on windoze (the D:\ sort of gives it away), so
permission issues are less likely but not impossible. How have you
configured apache? Which user does it use? What permissions are set on
the trac and target directories? Remember trac on windoze usually runs
as the apache user which is configured when you setup the service (did
you install yourself or use a packaged installer?)

From memory, the trac hotcopy script only works with sqlite ~ which
database backend are you using?

Hey,

I have a short question about creating custom fields in tickets.

I need the option to create a "Sub-Component" drop down menu. This field should be dependent on the component which the user chose. For example, choosing "component1" will result in the appearance of "sub-component1" and "sub-component2" in the "Sub-Component" drop down menu. Choosing other components may result in the appearance of other sub components.

Is this possible to implement? I couldn't find any easy configuration which enables this important option.

Thanks!
Nir

Yes i am running trac 0.11.5 on windows xp machine.I have configured
apache for the multi-project trac environment. Separate sqlite
database is used as the backend for both the project environment.
Apache is running with the previleges of Local System Account . Apache
2.0 had been installed in this machine before even i started with Trac
0.11.5 configuration.

In my previous setup in a different xp machine, the trac 0.10 version
has been congifured without Apache,i used the default method ,D:
\Python24\Scripts\tracd --port 8000 --auth trac,D:\myproj
\digest.txt,trac D:\proj, to start the tracd daemon. i was not getting
the [Error 13 Permission denied] when the hotcopy command was used.

I hope that i have given a clear idea on this issue.

Regards,
Balaji.

When you ran tracd it would have been running as you (unless you changed this when setting up as-a-service?). How do you have the hotcopy setup, do you run it interactively? Have you checked the permission settings on the source and target directories for the account that runs the hotcopy command?

Although less common on windoze, permissions for directories can be changed (I have done this to comply with my company's policies) to exclude most users and that does seem the mostr likely explanation at the moment. However, I do not use hotcopy myself as I use PostgreSQL backend...

Any chance someone has an answer for this issue?

We accomplished this by having compound components like "main/part1",
"main/part2", etc. and adding some JavaScript to the ticket handling
which parses on /, presents just the first part, and adds and populates
a second list box if the item selected in the first part has
subcomponents. Trac still thinks that there's only one component field
(in the db) but users can select subcomponents when creating or updating
tickets.

[yoheeb]

well, you should of started a new thread rather than hijack this one
for best results, however...
a better way to accomplish this may be to not use components. Keep
your components higher level, like "Software" "Documentation"
"Hardware"

and use the following plugin:
http://trac-hacks.org/wiki/TracTicketChainedFieldsPlugin

seems like what you are really after

Yes you are right when i was running the tracd service, it was
runnning with administrator privileges.I checked the permission of
Source (D:\proj\*.*) and Destination (D:\backup\*.*) , both have
administrator privileges.But i get the permission denied for no
reasons, but the environment is backed properly. As of now , i am not
using the tracd service, but i make use of Apache (httpd.conf) to
initiate the trac project environment.

How do you know that the backup works OK? Have you tried to restore one of the environments and check that there is nothing missing? Those messages would worry me but I am afraid that I have not other ideas at the moment.

I would need to look at the script and I don't have time for that. Try to work out exactly _what_ the script is trying to do when it fails, you will not get errors if there is nothing wrong...

The number of folder and files are similar in project source
environment and backup environment. Also the size of the trac.db is
same in both places. The error occurs from the below part of the code
(env.py), which i found in internet. The same code is not available
in my D:\python24\ installation directory.


try:
printout(_('Hotcopying %(src)s to %(dst)s ...',
src=self.env.path, dst=dest))
db_str = self.env.config.get('trac', 'database')
prefix, db_path = db_str.split(':', 1)
if prefix == 'sqlite':
# don't copy the journal (also, this would fail on
Windows)
db = os.path.join(self.env.path, os.path.normpath
(db_path))
skip = [db + '-journal', db + '-stmtjrnl']
else:
skip = []
try:
copytree(self.env.path, dest, symlinks=1, skip=skip)
retval = 0
except shutil.Error, e:
retval = 1
printerr(_('The following errors happened while
copying '
'the environment:'))
for (src, dst, err) in e.args[0]:
if src in err:
printerr(' %s' % err)
else:
printerr(" %s: '%s'" % (err, src))
finally:
# Unlock database
cnx.rollback()

printout(_("Hotcopy done."))
return retval
