commit fed0458e0db36a5ce00d463d479ac1c156f488d0
Author: Dianjin Wang <wangdian...@gmail.com>
AuthorDate: Tue Jul 29 17:21:42 2025 +0800

    License: add & clean up license headers and files
    
    This commit performs a comprehensive license compliance cleanup to align
    with release requirements, which are pointed out by Incubator PMC
    review.
    
    The main changes include:
    
    1. Add License Headers: Added the standard Apache License Version 2.0
      header to numerous source files that were missing it. This covers
      multiple file types, including YAML, Markdown, SQL, C/C++, Python,
      and shell scripts. These files are originally created by the
      cloudberry community.
    2. Simplify LICENSE and NOTICE:
      - Restructured the root LICENSE file for better clarity.
      - Cleaned up the NOTICE file by removing redundant information which
        have been listed in the LICENSE.
    3. Remove the unused deployment docs from the `deploy/build`, which can
      help us manage the file licenses.
    4. Update RAT Configuration: Updated `pom.xml` to reflect the changes of
       the file license headers and attribution.

 # CTID in  PAX
 
 Pax table is different from heap/ao table, for the last two bytes, it does't 
has continuous logical address. So it can't be mapped to physical file through 
ctid.

-# Compile and Install Apache Cloudberry on Linux
-
-This document shares how to compile and install Apache Cloudberry on Linux 
systems (CentOS 7, RHEL, and Ubuntu). Note that this document is for developers 
to try out Apache Cloudberry in a single-node environments. DO NOT use this 
document for production environments.
-
-Take the following steps to set up the development environments:
-
-1. [Clone the GitHub repo](#step-1-clone-the-github-repo).
-2. [Install dependencies](#step-2-install-dependencies).
-3. [Perform prerequisite platform 
tasks](#step-3-perform-prerequisite-platform-tasks).
-4. [Build Apache Cloudberry](#step-4-build-apache-cloudberry).
-5. [Verify the cluster](#step-5-verify-the-cluster).
-
-## Step 1. Clone the GitHub repo
-
-Clone the GitHub repository `apache/cloudberry` to the target machine:
-
-```shell
-git clone https://github.com/apache/cloudberry.git
-```
-
-## Step 2. Install dependencies
-
-Enter the repository and install dependencies according to your operating 
systems:
-
-- [For CentOS 7](#for-centos-7)
-- [For RHEL 8 or Rocky Linux 8](#for-rhel-8-or-rocky-linux-8)
-- [For Ubuntu 18.04 or later](#for-ubuntu-1804-or-later)
-
-### For CentOS 7
-
-> [!WARNING]
-> CentOS Linux 7 reached the end of life (EOL) on June 30, 2024. You can 
change the mirror to vault.centos.org to install software.
-
-The following steps work on CentOS 7. For other CentOS versions, these steps 
might work but are not guaranteed to work.
-
-1. Run the bash script `README.CentOS.bash` in the `deploy/build` directory of 
the `apache/cloudberry` repository. To run this script, password is required. 
Then, some required dependencies will be automatically downloaded.
-
-    ```bash
-    cd cloudberry/deploy/build
-    ./README.CentOS.bash
-    ```
-
-2. Install additional packages required for configurations.
-
-    ```bash
-    yum -y install R apr apr-devel apr-util automake autoconf bash bison 
bison-devel bzip2 bzip2-devel centos-release-scl curl flex flex-devel gcc 
gcc-c++ git gdb iproute krb5-devel less libcurl libcurl-devel libevent 
libevent-devel libxml2 libxml2-devel libyaml libzstd-devel libzstd make 
openldap openssh openssh-clients openssh-server openssl openssl-devel 
openssl-libs perl python3-devel readline readline-devel rsync sed sudo tar vim 
wget which xerces-c-devel zip zlib && \
-    yum -y install epel-release
-    ```
-
-3. Update the GNU Compiler Collection (GCC) to version `devtoolset-10` to 
support C++ 14.
-
-    ```bash
-    yum install centos-release-scl 
-    yum -y install devtoolset-10-gcc devtoolset-10-gcc-c++ 
devtoolset-10-binutils 
-    scl enable devtoolset-10 bash 
-    source /opt/rh/devtoolset-10/enable 
-    echo "source /opt/rh/devtoolset-10/enable" >> /etc/bashrc
-    source /etc/bashrc
-    gcc -v
-    ```
-
-4. Link cmake3 to cmake:
-
-    ```bash
-    sudo ln -sf /usr/bin/cmake3 /usr/local/bin/cmake
-    ```
-
-### For RHEL 8 or Rocky Linux 8
-
-1. Install Development Tools.
-
-    ```bash
-    sudo yum group install -y "Development Tools"
-    ```
-
-2. Install dependencies:
-
-    ```bash
-    sudo yum install -y epel-release
-
-    sudo yum install -y apr-devel bison bzip2-devel cmake3 flex gcc gcc-c++ 
krb5-devel libcurl-devel libevent-devel libkadm5  libxml2-devel libzstd-devel 
openssl-devel perl-ExtUtils-Embed python3-devel python3-pip readline-devel 
xerces-c-devel zlib-devel
-    ```
-
-3. Install more dependencies by running the `README.Rhel-Rocky.bash` script.
-
-    ```bash
-    ~/cloudberry/deploy/build/README.Rhel-Rocky.bash
-    ```
-
-### For Ubuntu 18.04 or later
-
-1. Install dependencies by running the `README.Ubuntu.bash` script in the 
`deploy/build` directory.
-
-    ```shell
-    # You need to enter your password to run.
-    sudo ~/cloudberry/deploy/build/README.Ubuntu.bash
-    ```
-
-    > [!Note]
-    > - When you run the `README.Ubuntu.bash` script for dependencies, you 
will be asked to configure `realm` for Kerberos. You can enter any realm, 
because this is just for testing, and during testing, it will reconfigure a 
local server/client. If you want to skip this manual configuration, run `export 
DEBIAN_FRONTEND=noninteractive`.
-    > - If the script fails to download packages, we recommend that you can 
try another one software source for Ubuntu.
-
-2. Install GCC 10. Ubuntu 18.04 and later versions should use GCC 10 or later:
-
-    ```bash
-    # Install gcc-10.
-    sudo apt install software-properties-common
-    sudo add-apt-repository ppa:ubuntu-toolchain-r/test
-    sudo apt install gcc-10 g++-10
-    sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 100
-    ```
-
-## Step 3. Perform prerequisite platform tasks
-
-After you have installed all the dependencies for your operating system, it is 
time to do some prerequisite platform tasks before you go on building Apache 
Cloudberry. These operations include manually running `ldconfig`, creating the 
`gpadmin` user, and setting up a password to start the Apache Cloudberry and 
test.
-
-1. Make sure that you add `/usr/local/lib` and `/usr/local/lib64` to the 
`/etc/ld.so.conf` file.
-
-    ```bash
-    echo -e "/usr/local/lib \n/usr/local/lib64" >> /etc/ld.so.conf
-    ldconfig
-    ```
-
-2. Create the `gpadmin` user and set up the SSH key. Manually create SSH keys 
based on different operating systems, so that you can run `ssh localhost` 
without a password.
-
-    - For CentOS, RHEL, and Rocky Linux:
-
-        ```bash
-        useradd gpadmin  # Creates gpadmin user
-        su - gpadmin  # Uses the gpadmin user
-        ssh-keygen  # Creates SSH key
-        cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
-        chmod 600 ~/.ssh/authorized_keys
-        exit
-        ```
-
-    - For Ubuntu:
-
-        ```bash
-        useradd -r -m -s /bin/bash gpadmin  # Creates gpadmin user
-        su - gpadmin  # Uses the gpadmin user
-        ssh-keygen  # Creates SSH key
-        cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
-        chmod 600 ~/.ssh/authorized_keys 
-        exit
-        ```
-
-## Step 4. Build Apache Cloudberry
-
-After you have installed all the dependencies and performed the prerequisite 
platform tasks, you can start to build Apache Cloudberry. Run the following 
commands in sequence.
-
-1. Configure the build environment. Enter the `cloudberry` directory and run 
the `configure` script.
-
-    ```bash
-    cd cloudberry
-    ./configure --with-perl --with-python --with-libxml --with-gssapi 
--prefix=/usr/local/cloudberry
-    ```
-
-    > [!Note]
-    > Cloudberry is built with GPORCA by default. If you want to build 
Cloudberry without GPORCA, add the `--disable-orca` flag in the `./configure` 
command.
-    >
-    > ```bash
-    > ./configure --disable-orca --with-perl --with-python --with-libxml 
--prefix=/usr/local/cloudberry
-    > ```
-
-2. Compile the code and install the database.
-
-    ```bash
-    make -j8
-    make -j8 install
-    ```
-
-3. Bring in the Cloudberry environment for your running shell.
-
-    ```bash
-    cd ..
-    cp -r cloudberry/ /home/gpadmin/
-    cd /home/gpadmin/
-    chown -R gpadmin:gpadmin cloudberry/
-    su - gpadmin
-    cd cloudberry/
-    source /usr/local/cloudberry/cloudberry-env.sh
-    ```
-
-4. Start the demo cluster.
-
-    - For CentOS:
-
-        ```bash
-        scl enable devtoolset-10 bash 
-        source /opt/rh/devtoolset-10/enable 
-        make create-demo-cluster
-        ```
-
-    - For Ubuntu, Rocky, and RHEL:
-
-        ```bash
-        make create-demo-cluster
-        ```
-
-5. Prepare the test by running the following command. This command will 
configure the port and environment variables for the test.
-
-    Environment variables such as `PGPORT` and `MASTER_DATA_DIRECTORY` will be 
configured, which are the default port and the data directory of the master 
node.
-
-    ```bash
-    source gpAux/gpdemo/gpdemo-env.sh
-    ```
-
-## Step 5. Verify the cluster
-
-1. You can verify whether the cluster has started successfully by running the 
following command. If successful, you can see multiple active `postgres` 
processes with ports ranging from `7000` to `7007`.
-
-    ```bash
-    ps -ef | grep postgres
-    ```
-    
-2. Connect to the Apache Cloudberry and see the active segment information by 
querying the system table `gp_segement_configuration`. For detailed description 
of this table, see the Greenplum document 
[here](https://docs.vmware.com/en/VMware-Greenplum/6/greenplum-database/ref_guide-system_catalogs-gp_segment_configuration.html).
-
-    ```sql
-    $ psql -p 7000 postgres
-    psql (14.4, server 14.4)
-    Type "help" for help.
-    
-    postgres=# select version();
-                                                                               
             version

-# Compile and Install Apache Cloudberry on macOS
-
-This document shares how to build, compile, and install Apache Cloudberry on 
macOS for development purposes. Follow the steps below.
-
-According to our test, these steps work well on macOS Ventura 13.4+ with both 
Intel and Apple silicon processors (M1 or M2). If you have an older version of 
macOS, upgrading is recommended.
-
-## Step 1. Install needed dependencies
-
-Run the following command to install the needed dependencies. You will be 
asked to enter the `sudo` password of your macOS system.
-
-```bash
-source deploy/build/README.macOS.bash
-```
-
-> [!NOTE]
-> This will install [Homebrew](https://brew.sh/) if missing.
-
-## Step 2. Enable password-free SSH connection to localhost
-
-1. Enable **Remote Login** on your macOS system by navigating to **System 
Preferences** \> **Sharing** \> **Remote Login**.
-2. Run the following command to verify whether password-free SSH connection to 
localhost has been enabled on your operating system.
-
-    ```bash
-    ssh $(hostname)
-    ```
-    
-    - If this command runs without error or requiring you to enter a password, 
run `exit` and go to [Step 3. Configure, compile, and 
install](#step-3-configure-compile-and-install).
-    - If you are required to enter a password, take the following steps to set 
up password-free SSH connection.
-
-        1. Run `ssh-keygen` and then `cat ~/.ssh/id_rsa.pub >>  
~/.ssh/authorized_keys`.
-        2. Run `ssh $(hostname)` again to check whether password-free 
connection is ready.
-        3. If ready, run `exit` and go to [Step 3. Configure, compile, and 
install](#step-3-configure-compile-and-install).
-
-> [!NOTE]
->
-> - If it is the first time you are using `ssh` connection to localhost, you 
might need to accept the trust on the first use prompt:
->
->    ```bash
->    The authenticity of host '<your hostname>' can't be established.
->    ECDSA key fingerprint is SHA256:<fingerprint here>.
->    Are you sure you want to continue connecting (yes/no)?
->   ```
->
-> - If your hostname does not resolve, try adding your machine name to 
`/etc/hosts`:
->
->    ```bash
->    echo -e "127.0.0.1\t$HOSTNAME" | sudo tee -a /etc/hosts
->    ```
-
-## Step 3. Configure, compile, and install
-
-```bash
-# Run the following commands under the `cloudberry/` dir.
-# 1. Configure the build environment.
-
-BREWPREFIX=$(brew --prefix); export 
PATH="$BREWPREFIX/opt/gnu-sed/libexec/gnubin:$BREWPREFIX/opt/apr/bin:$PATH"; 
CXXFLAGS="-I $BREWPREFIX/include" CFLAGS="-ggdb -Og -g3 -fno-omit-frame-pointer 
-I $BREWPREFIX/include" LDFLAGS="-L $BREWPREFIX/lib" CC=$(which gcc-13) 
CXX=$(which g++-13) ./configure --enable-debug --prefix=$(cd ~; 
pwd)/install/cbdb;
-
-# 2. Compile and install Apache Cloudberry.
-
-make -j8
-make -j8 install
-
-# 3. Bring in Cloudberry environment for Apache Cloudberry into your running 
shell.
-
-source $(cd ~; pwd)/install/cbdb/cloudberry-env.sh
-
-# 4. Install the Python dependencies.
-
-pip3 install --user -r python-dependencies.txt
-
-# 5. Start a demo cluster.
-
-PORT_BASE=8000 make create-demo-cluster
-
-# gpdemo-env.sh contains PGPORT, COORDINATOR_DATA_DIRECTORY and 
MASTER_DATA_DIRECTORY values
-source gpAux/gpdemo/gpdemo-env.sh
-```
-
-## Step 4. Verify the cluster
-
-1. You can verify whether the cluster has started successfully by running the 
following command. You will see many active `postgres` processes with ports 
ranging from `8000` to `8007`.
-
-    ```bash
-    ps -ef | grep postgres
-    ```
-    
-2. Connect to the Apache Cloudberry and see the active segment information by 
querying the system table `gp_segement_configuration`. For detailed description 
of this table, see the Greenplum document 
[here](https://docs.vmware.com/en/VMware-Greenplum/6/greenplum-database/ref_guide-system_catalogs-gp_segment_configuration.html).
-
-    ```sql
-    $ psql -p 8000 postgres
-    postgres=# select version();
-    postgres=# select * from gp_segment_configuration;
-    ```
-    
-    Example output:
-
-    ```shell
-    $ psql -p 8000 postgres
-    psql (14.4, server 14.4)
-    Type "help" for help.
-
-    postgres=# select version();
-                                                                               
              version

-3. Now we can finally run `installcheck-world` to test everything works fine:
-
-    ```bash
-    # In the folder where your cloned the source code
-    make installcheck-world
-    ```
-
-Congratulations 🎉! You've successfully installed and created a Cloudberry 
cluster. Happy Hacking! 😉

-# Build Apache Cloudberry from Source Code
-
-This guides describes how to build Apache Cloudberry from source code.
-
-- For building on Linux systems, see [Compile and Install Apache Cloudberry on 
Linux](./README.Linux.md).
-- For building on macOS system, see [Compile and Install Apache Cloudberry on 
macOS](./README.macOS.md).
-
-## Build the database
-
-```
-# Configure build environment to install at /usr/local/cloudberry
-./configure --with-perl --with-python --with-libxml --with-gssapi 
--prefix=/usr/local/cloudberry
-
-# Compile and install
-make -j8
-make -j8 install
-
-# Bring in cloudberry environment for CBDB into your running shell
-source /usr/local/cloudberry/cloudberry-env.sh
-
-# Start demo cluster
-make create-demo-cluster
-# (gpdemo-env.sh contains __PGPORT__, __COORDINATOR_DATA_DIRECTORY__ and 
__MASTER_DATA_DIRECTORY__ values)
-source gpAux/gpdemo/gpdemo-env.sh
-```
-
-- The directory and the TCP ports for the demo cluster can be changed on the 
fly.
-Instead of `make cluster`, consider:
-
-```
-DATADIRS=/tmp/cbdb-cluster PORT_BASE=5555 make cluster
-```
-
-- The TCP port for the regression test can be changed on the fly:
-
-```
-PGPORT=5555 make installcheck-world
-```
-
-- To turn GPORCA off and use Postgres planner for query optimization:
-```
-set optimizer=off;
-```
-
-- If you want to clean all generated files
-```
-make distclean
-```
-
-## Running tests
-
-* The default regression tests
-
-```
-make installcheck-world
-```
-
-* The top-level target __installcheck-world__ will run all regression
-  tests in CBDB against the running cluster. For testing individual
-  parts, the respective targets can be run separately.
-
-* The PostgreSQL __check__ target does not work. Setting up a
-  Apache Cloudberry cluster is more complicated than a single-node
-  PostgreSQL installation, and no-one's done the work to have __make
-  check__ create a cluster. Create a cluster manually or use
-  gpAux/gpdemo/ (example below) and run the toplevel __make
-  installcheck-world__ against that. Patches are welcome!
-
-* The PostgreSQL __installcheck__ target does not work either, because
-  some tests are known to fail with Apache Cloudberry. The
-  __installcheck-good__ schedule in __src/test/regress__ excludes
-  those tests.
-
-* When adding a new test, please add it to one of the CBDB-specific tests,
-  in greenplum_schedule, rather than the PostgreSQL tests inherited from the
-  upstream. We try to keep the upstream tests identical to the upstream
-  versions, to make merging with newer PostgreSQL releases easier.
-
-# Alternative Configurations
-
-## Building Apache Cloudberry without GPORCA
-
-Currently, CBDB is built with GPORCA by default. If you want to build CBDB
-without GPORCA, configure requires `--disable-orca` flag to be set.
-
-```
-# Clean environment
-make distclean
-
-# Configure build environment to install at /usr/local/cloudberry
-./configure --disable-orca --with-perl --with-python --with-libxml 
--prefix=/usr/local/cloudberry
-```
-
-## Building Apache Cloudberry with PXF
-
-PXF is an extension framework for Greenplum Database/Apache Cloudberry
-to enable fast access to external Hadoop datasets. Refer to
-[PXF extension](../../gpcontrib/pxf_fdw/README.md) for more information.
-
-Currently, Cloudberry is built with PXF by default (--enable-pxf is on).
-In order to build Cloudberry without pxf, simply invoke `./configure` with 
additional option `--disable-pxf`.
-PXF requires curl, so `--enable-pxf` is not compatible with the 
`--without-libcurl` option.
-
-## Building Apache Cloudberry with Python3 enabled
-
-Apache Cloudberry supports Python3 with plpython3u UDF
-
-See [how to enable Python3](../../src/pl/plpython/README.md) for details.
-
-
-# Development with Vagrant
-
-There is a Vagrant-based [quickstart guide for 
developers](../vagrant/README.md).
