SVN hook Application

I. Introduction to the SVN hook script

The specific wording of the hook script is the operating system shell script program, according to their own SVN operating system and shell program for the corresponding development.

A hook script is a program that is triggered by some repository events, such as creating a new version or modifying a property that is not versioned. Each hook can have enough information to understand what happened, what the object was, and the account of the user who triggered the event. Depending on the output or return status of the hook, the hook program can control the action in some way to continue, stop, or hang.

Introduction to SVN's hooks template feature

Start-commit triggering a transaction before committing

Pre-commit Trigger transaction before commit completes

Post-commit Trigger transaction when commit is complete

Pre-revprop-change triggers a transaction before the Version property is modified

Post-revprop-change The transaction is triggered after the version property is modified

Post-commit

After the commit is completed, the hook is executed after the version is successfully created, the commit is completed and cannot be changed, so the script return value is ignored

Post-lock

Execute the script after the file is locked

Post-revprop-change

After modifying the revision property, execute the script. Because the revision has been completed and cannot be changed, the return value of this script is ignored by the rice

(However, the actual implementation seems to be that the correct execution of the script affects the property modification)

Post-unlock

Execute the script after unlocking the file

Pre-commit

After subversion transaction is complete, execute the script before committing

Pre-revprop-change

Execute the script before modifying the revision property

Start-commit

Executes the script before the client has yet to submit data to the server, that is, before the Subversion Transaction (abbreviated TXN) has been established

By default, the sub-directory of hooks contains various repository hook templates
