xtrabackup not handling barracuda compressed table format

[vibhor]

Hello,

I am unable to run xtrabackup against a barracuda compressed table. Here is what happens:

xtrabackup --backup --target-dir=/backup --innodb_file_per_table
xtrabackup Ver 1.0 Rev 113 for 5.0.84 unknown-linux-gnu (x86_64)
xtrabackup: uses posix_fadvise().
xtrabackup: cd to /disk2/mysql

xtrabackup: innodb_log_group_home_dir = ./
xtrabackup: innodb_log_files_in_group = 2
xtrabackup: innodb_log_file_size = 536870912

This happens on both machines where I am using the barracuda compressed table format with percona's mysql release. On the two machines where I am running stock mysql with innodb I am able to complete the backup successfully.

Naturally, "for 5.0" version cannot treat Barracuda.
Building with InnoDB-Plugin is needed.

An update on this. I built the xtrabackup binary using the source code using mysql-5.1.34.tar.gz (source) and the xtrabackup-1.0.tar.gz (source). I used the build script: xtrabackup-1.0/innobase/xtrabackup/utils/build51tree.sh

The build failed while compiling xtrabackup, so I had to edit the xtrabackup-build/mysql-5.1.34/storage/innobase/xtrabackup/Makefile to comment out the MySQL 5.0 build instructions and uncomment the MySQL 5.1 build instructions. Then ran make to finish the building. Using this binary against a database with barracuda compressed tables I ran into the exact same errors as with the RHEL 5 binary RPM released by Percona built against MySQL 5.0. Here is the output:

./xtrabackup --backup --target-dir=/backup --innodb_file_per_table

Let me know if you need any more information. Perhaps my build method was flawed.

Forgot to add that I was unable to build the xtrabackup binary against the mysql-xtradb 5.1.34 source since patching fails. I will attempt to build against 5.1.34 with the InnoDB plugin.

I think that is the issue, since I didn't build it against the innodb-plugin (only vanilla mysql). So please disregard previous post.

The fix have been pushed.
