I did try but got the following. Forbidden TICKET_CREATE privileges are required to perform this operation I believe there is some interaction between the proxy we use at work and the trac. Other users in our organisation have also had the same problem.
XP or Vista?

Setup.hs: ..\..\haskell_packages\doc\zlib-0.5.0.0\.copyFile920.tmp: copyFile: permission denied (Access is denied.)
Cabal seesm to create certain things as read only. I can work around this by
We use System.Directory.copyFile which copies the permissions from the original file to the destination file. Could you confirm that this is working correctly. Are the permissions of the source and destination files exactly the same? Was the source file created read-only?
haskell_packages is empty to start with and the package gets built successfully. Attributes are copied over successfully. The actual source files *are* read only as they are kept in our source control system which marks them this way for unchecked out files. Built files are read / write.

When I rebuild the package *without* having cleaned out haskell_packages then I get the access error. I think this is because cabal (copyFile) doesn't want to overwrite a read only file even though the directory permissions should allow it to do so.
This looks like: http://hackage.haskell.org/trac/hackage/ticket/454
But for every file not just .exe files. For .exe files Cabal does the permission copying itself. I do not understand why it just started occurring, since ghc-6.8 and 6.10 seem to have the same code for copyFile and copyPermissions.
I don't seem to have the problem for binaries (because cabal builds them afresh with read / write permission) so I don't know if it's related or not (but it seems unlikely).

We'll need more help to understand and fix this one. I think the right solution will be that we do not copy permissions at all but either set permissions to precise values or do nothing and use defaults. On Unix we
That seems the correct thing to do. Let me know if you need any more information. Dominic.
