Source browser permission problem with files created with 'svn copy'

[Vincent B <vincent.boucher@…>]

Hello,

There's a bug (or I presume so) with permissions when a private directory is copied (with 'svn copy') as a new public directory. The children files inherits the permissions set from the initial directory (private) until they gets modified.

The permissions are set in the AuthzPolicy conf file. The problem appears also when setting permissions with AuthzSourcePolicy. When browsing the repository with the apache/webdav/svn sequence and the same authz file as the one used for AuthzSourcePolicy, there's no problem. So I infer it as a Trac problem and not a svn one.

Example:

State 1

Repository state before the 'svn copy':

Directory/File	Revision #	Viewable by anonymous?
/private/	1	No
fileA	1	No

---

State 2

Then, we

$ svn copy private public
A         public
$ svn commit
Adding         public

Committed revision 2.

Let's allow the 'public' dir to be viewable by everybody with the following AuthzPolicy conf file (excerpt):

[repository:*@*/source:/@*]
* = BROWSER_VIEW
[repository:*@*/source:public@*]
* = BROWSER_VIEW
[repository:*@*/source:public/*@*]
* = BROWSER_VIEW, FILE_VIEW

Now, the repository looks as:

Directory/File	Revision #	Viewable by anonymous?
/private/	1	No
fileA	1	No
/public/	2	Yes
fileA	1	No !!! :-(

The bug: while the 'public' folder can be browsed as an anonymous user, fileA doesn't shows up in the file list of the Trac Browser! :-(

---

State 3

We can add a new file in public (fileB)

$ touch public/fileB
$ svn add public/fileB
A         public/fileB
$ svn commit
Adding         public/fileB
Transmitting file data .
Committed revision 3.

Repository state after commit:

Directory/File	Revision #	Viewable by anonymous?
/private/	1	No
fileA	1	No
/public/	3	Yes
fileA	1	No !!!
fileB	3	Yes

fileB displays in the file list of the Trac Browser and its content can be viewed by anonymous (fileA doesn't).

---

State 4

Finally, modifying public/fileA renders it viewable by anonymous:

$ echo 'yoplaboum' >> public/fileA
$ svn commit
Sending        public/fileA
Transmitting file data .
Committed revision 4.

Directory/File	Revision #	Viewable by anonymous?
/private/	1	No
fileA	1	No
/public/	4	Yes
fileA	4	Yes
fileB	3	Yes

---

Summary: State 2 and 3 are not correctly handled by Trac.

---

Note that at State ≥2 , fileA is correctly displayed when listed/viewed through apache/webdav/svn.

Very nice bug report, thank you.

I think this is actually a duplicate of #9976.

[Remy Blank]

I assume you meant to close, then.

[Christian Boos]

Actually the reported use case also covers the AuthzPolicy in addition to the AuthzSourcePolicy. As #9976 and #10208 only focus on the latter, let's use this ticket for mentioning the change affecting the former policy.
