* server-lookup: added path info from header to log messageAmar Tumballi2009-08-041-3/+4
| | | | | | | | | | | | in the previous commit, the path info was removed to prevent the segfault, which instead could have been provided from request header directly. More specific information is required for debugging, and hence adding the path log. Signed-off-by: Anand V.

* increased ib-verbs buffer sizeAmar Tumballi2009-08-041-2/+2
| | | | | | | | | | | | | Noticed that in few cases, where ib-verbs doesn't handle a bigger sized buffer to be sent across, which happens without problem in tcp. Caused frame losses in the case where server's reply msg was bigger, hence the msg got dropped at the server end. With this patch ib-verbs buffer size is fixed to 512KB.

* libglusterfsclient: Bind fd on fd creation code pathsShehjar Tikoo2009-07-312-3/+9
| | | | | | | | | | | | | | When an fd_t is fd_create'd, we need to call fd_bind on it to ensure that any fd_lookup on the inode gets us this fd. We're not doing this so translators like write-behind were not able to order path-based requests at all resulting in some fops like stat, which could be issued after a writev, overtaking a previous writev which is still being written-behind.

* libglusterfsclient: Use iobufs for storing application write dataShehjar Tikoo2009-07-302-18/+85
| | | | | | | | | | | | | | | | | | | | | Till now we've been creating an iovec, storing references in it to the application data and simply passing it on to the translator tree. This means that the buffer being passed to the translators is not at all associated with the memory ref'd by the iobref argument to write fop. This is a problem when write-behind is a translator in the tree since it assumes that the memory in the iovecs passed to write fops is already refcounted by the iobref and so it simply copies the address of the application data. The problem is that the application can continue using this buffer, free it or over-write it destroying the data that write-behind may write at a later time. The solution involves copying the application's write buffer into an iobuf which will be referred to by the iobref. Signed-off-by: Anand V.

* libglusterfsclient: Avoid overwrite of inode found through ino numberShehjar Tikoo2009-07-271-3/+8
| | | | | | | | | | | | | | | | | In libgf_client_loc_fill, there is a possibility that all the ino, par and name are specified as non-NULL,non-zero args. So if an inode is located in the itable using the ino and the subsequent search for the inode using the par-ino and the file name does not result in an inode being found, the current code over-writes the inode that was found through the ino. The correct behaviour is to stop further searches if inode was already found using ino. Signed-off-by: Anand V.
