# This script allows to easily generate (add or update) "--release N" data for JDK N + 1.

# N must be 11 or greater. This script works on Linux. To create new data, or update existing

# data, it is necessary to:

# - download a binary build of OpenJDK N for Linux, API of which will be recorded. It is strongly recommended

#   to use an official build, not a custom build, to avoid any chance of including unofficial changes.

#   The binary build should never be a build newer than the GA for JDK N. Install the build. The installation

#   directory will be denoted as "${JDK_N_INSTALL}" in the further text.

# - have a checkout the JDK to which the data should be added (or in which the data should be updated).

#   The checkout directory will be denoted as "${JDK_CHECKOUT}" in the further text.

#   The checkout must not have any local changes that could interfere with the new data. In particular,

#   there must be absolutely no changed, new or removed files under the ${JDK_CHECKOUT}/make/data/symbols

#   directory.

# - open a terminal program and run these commands:

#     cd "${JDK_CHECKOUT}"/make/data/symbols

#     bash ../../scripts/generate-symbol-data.sh "${JDK_N_INSTALL}"

# - this command will generate or update data for "--release N" into the ${JDK_CHECKOUT}/make/data/symbols

#   directory, updating all registration necessary. If the goal was to update the data, and there are no

#   new or changed files in the ${JDK_CHECKOUT}/make/data/symbols directory after running this script,

#   there were no relevant changes and no further action is necessary. Note that version for N > 9 are encoded

#   using capital letters, i.e. A represents version 10, B represents 11, and so on. The version numbers are in

#   the names of the files in the ${JDK_CHECKOUT}/make/data/symbols directory, as well as in

#   the ${JDK_CHECKOUT}/make/data/symbols/symbols file.

# - if there are any changed/new files in the ${JDK_CHECKOUT}/make/data/symbols directory after running this script,

#   then all the changes in this directory, including any new files, need to be sent for review and eventually pushed.

#   The commit message should specify which binary build was installed in the ${JDK_N_INSTALL} directory and also

#   include the SCM state that was used to build it, which can be found in ${JDK_N_INSTALL}/release,

#   in property "SOURCE".
