Interactive conflict handling.
This API gives a Subversion client application the opportunity to define a callback that allows the user to resolve conflicts interactively during updates and merges.
If a conflict is discovered, libsvn_wc invokes the callback with an svn_wc_conflict_description_t. This structure describes the path in conflict, whether it's a text or property conflict, and may also present up to three files that can be used to resolve the conflict (perhaps by launching an editor or 3rd-party merging tool). The structure also provides a possible fourth file (merged_file) which, if not NULL, represents libsvn_wc's attempt to contextually merge the first three files. (Note that libsvn_wc will not attempt to merge a file that it believes is binary, and it will only attempt to merge property values it believes to be a series of multi-line text.)
When the callback is finished interacting with the user, it responds by returning a svn_wc_conflict_result_t. This structure indicates whether the user wants to postpone the conflict for later (allowing libsvn_wc to mark the path "conflicted" as usual), or whether the user wants libsvn_wc to use one of the four files as the "final" state for resolving the conflict immediately.
Note that the callback is at liberty (and encouraged) to merge the three files itself. If it does so, it signals this to libsvn_wc by returning a choice of svn_wc_conflict_choose_merged. To return the 'final' merged file to libsvn_wc, the callback has the option of either:
editing the original merged_file in-place
or, if libsvn_wc never supplied a merged_file in the description structure (i.e. passed NULL for that field),
| typedef enum svn_wc_conflict_action_t svn_wc_conflict_action_t |
The type of action being attempted on an object.
| typedef enum svn_wc_conflict_choice_t svn_wc_conflict_choice_t |
The way in which the conflict callback chooses a course of action.
| typedef struct svn_wc_conflict_description2_t svn_wc_conflict_description2_t |
A struct that describes a conflict that has occurred in the working copy.
The conflict described by this structure is one of:
| typedef struct svn_wc_conflict_description_t svn_wc_conflict_description_t |
Similar to svn_wc_conflict_description2_t, but with relative paths and adm_access batons.
Passed to svn_wc_conflict_resolver_func_t.
| typedef enum svn_wc_conflict_kind_t svn_wc_conflict_kind_t |
The type of conflict being described by an svn_wc_conflict_description2_t (see below).
| typedef enum svn_wc_conflict_reason_t svn_wc_conflict_reason_t |
The pre-existing condition which is causing a state of conflict.
| typedef svn_error_t*(* svn_wc_conflict_resolver_func2_t) (svn_wc_conflict_result_t **result, const svn_wc_conflict_description2_t *description, void *baton, apr_pool_t *result_pool, apr_pool_t *scratch_pool) |
A callback used in merge, update and switch for resolving conflicts during the application of a tree delta to a working copy.
description describes the exact nature of the conflict, and provides information to help resolve it. baton is a closure object; it should be provided by the implementation, and passed by the caller. When finished, the callback signals its resolution by returning a structure in *result, which should be allocated in result_pool. (See svn_wc_conflict_result_t.) scratch_pool should be used for any temporary allocations.
The values svn_wc_conflict_choose_mine_conflict and svn_wc_conflict_choose_theirs_conflict are not legal for conflicts in binary files or binary properties.
Implementations of this callback are free to present the conflict using any user interface. This may include simple contextual conflicts in a file's text or properties, or more complex 'tree'-based conflicts related to obstructed additions, deletions, and edits. The callback implementation is free to decide which sorts of conflicts to handle; it's also free to decide which types of conflicts are automatically resolvable and which require user interaction.

The final result returned by svn_wc_conflict_resolver_func_t.

The type of action being attempted on an object.
The way in which the conflict callback chooses a course of action.
