abapGit contains predefined user exits which can be used to modify the standard behavior.


If the compiled report is installed, create include `ZABAPGIT_USER_EXIT` and add local class `ZCL_ABAPGIT_USER_EXIT` implementing `ZIF_ABAPGIT_EXIT`.

If the development version is installed create global class `ZCL_ABAPGIT_USER_EXIT` implementing `ZIF_ABAPGIT_EXIT`.

In both cases add the object in a package different from the main abapGit code.

The list of user exits can change at any time, make sure to syntax check user exits after upgrade of abapGit.

### CHANGE_LOCAL_HOST
If the hostnames are not properly configured, this exit can be used to modify the settings.
This is especially useful when running abapGitServer on the local system.

### ALLOW_SAP_OBJECTS
Force allowing serialization of SAP objects.

### CHANGE_PROXY_URL
todo

### CHANGE_PROXY_PORT
todo

### CHANGE_PROXY_AUTHENTICATION
todo

### CREATE_HTTP_CLIENT
Store username and password in RFC connection setup, see [https://github.com/abapGit/abapGit/issues/1841](https://github.com/abapGit/abapGit/issues/1841)

### HTTP_CLIENT
Can be used for setting logon tickets eg. in connection with abapGitServer connections between SAP systems.
Example: [https://gist.github.com/larshp/71609852a79aa1e877f8c4020d18feac](https://gist.github.com/larshp/71609852a79aa1e877f8c4020d18feac)

### CHANGE_TADIR
Can be used to skip certain objects, or force a different object setup than currently in TADIR.
Example: [https://gist.github.com/larshp/cca0ce0ba65efcde5dfcae416b0484f7](https://gist.github.com/larshp/cca0ce0ba65efcde5dfcae416b0484f7)

### GET_SSL_ID
Possibility to change the default `ANONYM` ssl id to something system specific

### CUSTOM_SERIALIZE_ABAP_CLIF
Allows for a custom serializer to be used for global classes' CLIF sources. See [#2321](https://github.com/abapGit/abapGit/issues/2321) and [#2491](https://github.com/abapGit/abapGit/pull/2491) for use cases.
This [example implementation](https://gist.github.com/flaiker/999c8165b89131608b05cd371529fef5) forces the old class serializer to be used for specific packages.

### DESERIALIZE_POSTPROCESS
Can be used for any postprocessing operation for deserialized objects. Since it is a postprocessing step, only logs can be added to II_LOG and one should not terminate the process by raising exception, which may lead to inconsistencies.

### ADJUST_DISPLAY_COMMIT_URL
Can be used to set the URL to display a commit. There are default implementations for some providers:

| Provider  | Repo URL | Show Commit URL |
|-----------|----------|-----------------|
| github    | http(s):\/\/github.com/<user\>/\<repo\>.git    | http(s):\/\/github.com/<user\>/\<repo\>/commit/<sha1\>     |
| bitbucket | http(s):\/\/bitbucket.org/<user\>/\<repo\>.git | http(s):\/\/bitbucket.org/<user\>/\<repo\>/commits/<sha1\> |
| gitlab    | http(s):\/\/gitlab.com/<user\>/\<repo\>.git    | http(s):\/\/gitlab.com/\<user\>/\<repo\>/-/commit/<sha1\>  |

### PRE_CALCULATE_REPO_STATUS

Can be used to modify local and remote files before calculating diff status. Useful to remove diffs which are caused by deployment between different system version. See also: [abapgit xml stripper plugin](https://github.com/sbcgua/abapgit_xml_stripper_plugin)

The exit also receives a repo meta data snapshot (`zif_abapgit_persistence=>ty_repo`) to identify the repo and it's attributes in the current system (e.g. package). This can be used to enable/disable the exit for specific repos.
