## SVN_RA_ABI_VERSION

#define SVN_RA_ABI_VERSION 2

The current ABI (Application Binary Interface) version for the RA plugin model.

This version number will change when the ABI between the SVN core (e.g. libsvn_client) and the RA plugin changes.

An RA plugin should verify that the passed version number is acceptable before accessing the rest of the parameters, and before returning any information.

It is entirely acceptable for an RA plugin to accept multiple ABI versions. It can simply interpret the parameters based on the version, and it can return different plugin structures.

    VSN  DATE        REASON FOR CHANGE
    ---  ----------  ------------------------------------------------
      1  2001-02-17  Initial revision.
      2  2004-06-29  Preparing for svn 1.1, which adds new RA vtable funcs.
         2005-01-19  Rework the plugin interface and don't provide the vtable
                     to the client.  Separate ABI versions are no longer used.

Deprecated
  Provided for backward compatibility with the 1.0 API.

## Typedef Documentation

## svn_ra_callbacks2_t

typedef struct svn_ra_callbacks2_t svn_ra_callbacks2_t

A collection of callbacks implemented by libsvn_client which allows an RA layer to "pull" information from the client application, or possibly store information.

libsvn_client passes this vtable to svn_ra_open5().

Each routine takes a callback_baton originally provided with the vtable.

Clients must use svn_ra_create_callbacks() to allocate and initialize this structure.

Since
  New in 1.3.

## svn_ra_callbacks_t

typedef struct svn_ra_callbacks_t svn_ra_callbacks_t

Similar to svn_ra_callbacks2_t, except that the progress notification function and baton is missing.

Deprecated
  Provided for backward compatibility with the 1.2 API.

## svn_ra_check_tunnel_func_t

typedef svn_boolean_t(* svn_ra_check_tunnel_func_t) (void *tunnel_baton, const char *tunnel_name)

Callback function that checks if an ra_svn tunnel called tunnel_name is handled by the callbakcs or the default implementation.

tunnel_baton is the baton as originally passed to ra_open.

Since
  New in 1.9.

Definition at line 283 of file svn_ra.h.

## svn_ra_close_tunnel_func_t

typedef void(* svn_ra_close_tunnel_func_t) (void *close_baton, void *tunnel_baton)

Callback function for closing a tunnel in ra_svn.

This function will be called when the pool that owns the tunnel connection is cleared or destroyed.

close_baton is the baton as returned from the svn_ra_open_tunnel_func_t.

tunnel_baton was returned by the open-tunnel callback.

Since
  New in 1.9.

Definition at line 299 of file svn_ra.h.

## svn_ra_dirent_receiver_t

typedef svn_error_t *(* svn_ra_dirent_receiver_t) (const char *rel_path, svn_dirent_t *dirent, void *baton, apr_pool_t *scratch_pool)

Callback type to be used with svn_ra_list().

It will be invoked for every directory entry found.

The full path of the entry is given in rel_path and dirent contains various additional information. Only the elements of dirent specified by the dirent_fields argument to svn_ra_list() will be valid.

baton is the user-provided receiver baton. scratch_pool may be used for temporary allocations.

Since
  New in 1.10.

Definition at line 1171 of file svn_ra.h.

## svn_ra_file_rev_handler_t

typedef svn_error_t *(* svn_ra_file_rev_handler_t) (void *baton, const char *path, svn_revnum_t rev, apr_hash_t *rev_props, svn_txdelta_window_handler_t *delta_handler, void **delta_baton, apr_array_header_t *prop_diffs, apr_pool_t *pool)

A callback function type for use in `get_file_revs`.

baton is provided by the caller, path is the pathname of the file in revision rev and rev_props are the revision properties. If delta_handler and delta_baton are non-NULL, they may be set to a handler/baton which will be called with the delta between the previous revision and this one after the return of this callback. They may be left as NULL/NULL. prop_diffs is an array of svn_prop_t elements indicating the property delta for this and the previous revision. pool may be used for temporary allocations, but you can't rely on objects allocated to live outside of this particular call and the immediately following calls to *delta_handler, if any.

Since
  New in 1.1.

Definition at line 174 of file svn_ra.h.

## svn_ra_get_client_string_func_t

typedef svn_error_t *(* svn_ra_get_client_string_func_t) (void *baton, const char **name, apr_pool_t *pool)

A function type which allows the RA layer to ask about any customizations to the client name string.

This is primarily used by HTTP-based RA layers wishing to extend the string reported to Apache/mod_dav_svn via the User-agent HTTP header.

Since
  New in 1.5.

Definition at line 152 of file svn_ra.h.

## svn_ra_get_latest_revnum_func_t

typedef svn_error_t *(* svn_ra_get_latest_revnum_func_t) (void *session_baton, svn_revnum_t *latest_revnum)

A function type for retrieving the youngest revision from a repos.

Deprecated
  Provided for backward compatibility with the 1.8 API.

Definition at line 141 of file svn_ra.h.

## svn_ra_get_wc_contents_func_t

typedef svn_error_t *(* svn_ra_get_wc_contents_func_t) (void *baton, svn_stream_t **contents, const svn_checksum_t *checksum, apr_pool_t *pool)

This is a function type which allows the RA layer to fetch the cached pristine file contents whose checksum is checksum, if any.

*contents will be a read stream containing those contents if they are found; NULL otherwise.

Since
  New in 1.8.

Definition at line 130 of file svn_ra.h.

## svn_ra_get_wc_prop_func_t

typedef svn_error_t *(* svn_ra_get_wc_prop_func_t) (void *baton, const char *path, const char *name, const svn_string_t **value, apr_pool_t *pool)

This is a function type which allows the RA layer to fetch working copy (WC) properties.

The baton is provided along with the function pointer and should be passed back in. This will be the callback_baton or the close_baton as appropriate.

path is relative to the "root" of the session, defined by the repos_URL passed to svn_ra_open5() vtable call.

name is the name of the property to fetch. If the property is present, then it is returned in value. Otherwise, *value is set to `NULL`.

Definition at line 73 of file svn_ra.h.

## svn_ra_init_func_t

typedef svn_error_t *(* svn_ra_init_func_t) (int abi_version, apr_pool_t *pool, apr_hash_t *hash)

All "ra_FOO" implementations must export a function named svn_ra_FOO_init() of type `svn_ra_init_func_t`.

When called by libsvn_client, this routine adds an entry (or entries) to the hash table for any URL schemes it handles. The hash value must be of type (`svn_ra_plugin_t` *). pool is a pool for allocating configuration / one-time data.

This type is defined to use the "C Calling Conventions" to ensure that abi_version is the first parameter. The RA plugin must check that value before accessing the other parameters.

### need to force this to be __cdecl on Windows... how??

Deprecated
  Provided for backward compatibility with the 1.1 API.

Definition at line 2555 of file svn_ra.h.

## svn_ra_invalidate_wc_props_func_t

typedef svn_error_t *(* svn_ra_invalidate_wc_props_func_t) (void *baton, const char *path, const char *name, apr_pool_t *pool)

This is a function type which allows the RA layer to invalidate (i.e., remove) wcprops recursively.

See the documentation for `svn_ra_get_wc_prop_func_t` for baton, path, and name.

Unlike `svn_ra_push_wc_prop_func_t`, this has immediate effect. If it returns success, the wcprops have been removed.

Definition at line 118 of file svn_ra.h.

## svn_ra_lock_callback_t

typedef svn_error_t *(* svn_ra_lock_callback_t) (void *baton, const char *path, svn_boolean_t do_lock, const svn_lock_t *lock, svn_error_t *ra_err, apr_pool_t *pool)

Callback function type for locking and unlocking actions.

Since
  New in 1.2.

do_lock is TRUE when locking path, and FALSE otherwise.

lock is a lock for path or NULL if do_lock is FALSE or ra_err is non-NULL.

ra_err is NULL unless the ra layer encounters a locking related error which it passes back for notification purposes. The caller is responsible for clearing ra_err after the callback is run.

baton is a closure object; it should be provided by the implementation, and passed by the caller. pool may be used for temporary allocation.

Definition at line 203 of file svn_ra.h.

## svn_ra_open_tunnel_func_t

typedef svn_error_t *(* svn_ra_open_tunnel_func_t) (svn_stream_t **request, svn_stream_t **response, svn_ra_close_tunnel_func_t *close_func, void **close_baton, void *tunnel_baton, const char *tunnel_name, const char *user, const char *hostname, int port, svn_cancel_func_t cancel_func, void *cancel_baton, apr_pool_t *pool)

Callback function for opening a tunnel in ra_svn.

Given the tunnel_name, tunnel user and server hostname and port, open a tunnel to the server and return its file handles, which are owned by pool, in request and response.

request and response represent the standard input and output, respectively, of the process on the other end of the tunnel.

If *close_func is set it will be called with close_baton when the tunnel is closed.

The optional cancel_func callback can be invoked as usual to allow the user to preempt potentially lengthy operations.

tunnel_baton is the baton as set in the callbacks.

Since
  New in 1.9.

Definition at line 322 of file svn_ra.h.

## svn_ra_plugin_t

typedef struct svn_ra_plugin_t svn_ra_plugin_t

Using this callback struct is similar to calling the newer public interface that is based on `svn_ra_session_t`.

Deprecated
  Provided for backward compatibility with the 1.1 API.

## svn_ra_progress_notify_func_t

typedef void(* svn_ra_progress_notify_func_t) (apr_off_t progress, apr_off_t total, void *baton, apr_pool_t *pool)

Callback function type for progress notification.

progress is the number of bytes already transferred, total is the total number of bytes to transfer or -1 if it's not known, baton is the callback baton.

Since
  New in 1.3.

Definition at line 219 of file svn_ra.h.

## svn_ra_push_wc_prop_func_t

typedef svn_error_t *(* svn_ra_push_wc_prop_func_t) (void *baton, const char *path, const char *name, const svn_string_t *value, apr_pool_t *pool)

This is a function type which allows the RA layer to store new working copy properties as part of a commit.

See the comments for `svn_ra_get_wc_prop_func_t` for baton, path, and name. The value is the value that will be stored for the property; a `NULL` value means the property will be deleted.

Note that this might not actually store the new property before returning, but instead schedule it to be changed as part of post-commit processing (in which case a successful commit means the properties got written). Thus, during the commit, it is possible to invoke this function to set a new value for a wc prop, then read the wc prop back from the working copy and get the old value. Callers beware.

Definition at line 105 of file svn_ra.h.

## svn_ra_replay_revfinish_callback_t

typedef svn_error_t *(* svn_ra_replay_revfinish_callback_t) (svn_revnum_t revision, void *replay_baton, const svn_delta_editor_t *editor, void *edit_baton, apr_hash_t *rev_props, apr_pool_t *pool)

Callback function type for replay_range actions.

This callback function should close the editor.

revision is the target revision number of the received replay report.

editor and edit_baton are the values provided by the REVSTART callback.

replay_baton is the baton as originally passed to replay_range.

revprops contains key/value pairs for each revision properties for this revision.

Since
  New in 1.5.

Definition at line 265 of file svn_ra.h.

## svn_ra_replay_revstart_callback_t

typedef svn_error_t *(* svn_ra_replay_revstart_callback_t) (svn_revnum_t revision, void *replay_baton, const svn_delta_editor_t **editor, void **edit_baton, apr_hash_t *rev_props, apr_pool_t *pool)

Callback function type for replay_range actions.

This callback function should provide replay_range with an editor which will be driven with the received replay reports from the master repository.

revision is the target revision number of the received replay report.

*editor and *edit_baton should provided by the callback implementation.

replay_baton is the baton as originally passed to replay_range.

revprops contains key/value pairs for each revision properties for this revision.

Since
  New in 1.5.

Definition at line 241 of file svn_ra.h.

## svn_ra_reporter2_t

typedef struct svn_ra_reporter2_t svn_ra_reporter2_t

Similar to `svn_ra_reporter3_t`, but without support for depths.

Deprecated
  Provided for backward compatibility with the 1.4 API.

## svn_ra_reporter3_t

typedef struct svn_ra_reporter3_t svn_ra_reporter3_t

The update Reporter.

A vtable structure which allows a working copy to describe a subset (or possibly all) of its working-copy to an RA layer, for the purposes of an update, switch, status, or diff operation.

Paths for report calls are relative to the target (not the anchor) of the operation. Report calls must be made in depth-first order: parents before children, all children of a parent before any siblings of the parent. The first report call must be a set_path with a path argument of "" and a valid revision. (If the target of the operation is locally deleted or missing, use the anchor's revision.) If the target of the operation is deleted or switched relative to the anchor, follow up the initial set_path call with a link_path or delete_path call with a path argument of "" to indicate that. In no other case may there be two report descriptions for the same path. If the target of the operation is a locally added file or directory (which previously did not exist), it may be reported as having revision 0 or as having the parent directory's revision.

Since
  New in 1.5.

## svn_ra_reporter_t

typedef struct svn_ra_reporter_t svn_ra_reporter_t

Similar to `svn_ra_reporter2_t`, but without support for lock tokens.

Deprecated
  Provided for backward compatibility with the 1.1 API.

## svn_ra_session_t

typedef struct svn_ra_session_t svn_ra_session_t

A repository access session.

This object is used to perform requests to a repository, identified by a URL.

Since
  New in 1.2.

Definition at line 685 of file svn_ra.h.

## svn_ra_set_wc_prop_func_t

typedef svn_error_t *(* svn_ra_set_wc_prop_func_t) (void *baton, const char *path, const char *name, const svn_string_t *value, apr_pool_t *pool)

This is a function type which allows the RA layer to store new working copy properties during update-like operations.

See the comments for `svn_ra_get_wc_prop_func_t` for baton, path, and name. The value is the value that will be stored for the property; a NULL value means the property will be deleted.

svn_error_t * svn_ra_change_rev_prop | ( | svn_ra_session_t * | session,
|  | svn_revnum_t | rev,
|  | const char * | name,

Similar to svn_ra_change_rev_prop2(), but with old_value_p set to `NULL`.

Since
  New in 1.2.

Deprecated
  Provided for backward compatibility with the 1.6 API.

## svn_ra_change_rev_prop2()

svn_error_t * svn_ra_change_rev_prop2 | ( | svn_ra_session_t * | session,

|  | const char * | name,
|  | const svn_string_t *const * | old_value_p,
|  | const svn_string_t * | value,
|  | apr_pool_t * | pool )

Set the property name to value on revision rev in the repository of session.

If value is `NULL`, delete the named revision property.

If the server advertises the SVN_RA_CAPABILITY_ATOMIC_REVPROPS capability and old_value_p is not `NULL`, then changing the property will fail with an error chain that contains SVN_ERR_FS_PROP_BASEVALUE_MISMATCH if the present value of the property is not *old_value_p. (This is an atomic test-and-set). *old_value_p may be `NULL`, representing that the property must be not already set.

If the capability is not advertised, then old_value_p MUST be `NULL`.

Please note that properties attached to revisions are unversioned.

## svn_ra_do_diff3()

svn_error_t * svn_ra_do_diff3 | ( | svn_ra_session_t * | session,

|  | const char * | versus_url,
|  | const svn_delta_editor_t * | diff_editor,
|  | void * | diff_baton,
|  | apr_pool_t * | pool )

Ask the RA layer to 'diff' a working copy against versus_url; it's another form of svn_ra_do_update2().

Note
  This function cannot be used to diff a single file, only a working copy directory. See the svn_ra_do_switch3() function for more details.

The client initially provides a diff_editor/diff_baton to the RA layer; this editor contains knowledge of where the common diff root is in the working copy (when open_root() is called).

In return, the client receives a reporter/report_baton. The client then describes its working copy by making calls into the reporter.

When finished, the client calls reporter->finish_report(). The RA layer then does a complete drive of diff_editor, ending with close_edit(), to transmit the diff.

diff_target is an optional single path component will restrict the scope of the diff to an entry in the directory represented by the session's URL, or empty if the entire directory is meant to be one of the diff paths.

The working copy will be diffed against versus_url as it exists in revision revision, or as it is in head if revision is `SVN_INVALID_REVNUM`.

Use ignore_ancestry to control whether or not items being diffed will be checked for relatedness first. Unrelated items are typically transmitted to the editor as a deletion of one thing and the addition of another, but if this flag is `TRUE`, unrelated items will be diffed as if they were related.

Diff only as deeply as depth indicates.

The caller may not perform any RA operations using session before finishing the report, and may not perform any RA operations using session from within the editing operations of diff_editor.

text_deltas instructs the driver of the diff_editor to enable the generation of text deltas. If text_deltas is FALSE the window handler returned by apply_textdelta will be called once with a NULL `svn_txdelta_window_t` pointer.

Use pool for memory allocation.

Note
  The reporter provided by this function does NOT supply copy- from information to the diff editor callbacks.
  In order to prevent pre-1.5 servers from doing more work than needed, and sending too much data back, a pre-1.5 'recurse' directive may be sent to the server, based on depth.

|  | apr_pool_t * | pool )

Ask the RA layer to describe the status of a working copy with respect to revision of the repository (or HEAD, if revision is invalid).

The client initially provides a status_editor/status_baton to the RA layer; this editor contains knowledge of where the change will begin in the working copy (when open_root() is called).

In return, the client receives a reporter/report_baton. The client then describes its working copy by making calls into the reporter.

When finished, the client calls reporter->finish_report(). The RA layer then does a complete drive of status_editor, ending with close_edit(), to report, essentially, what would be modified in the working copy were the client to call do_update(). status_target is an optional single path component will restrict the scope of the status report to an entry in the directory represented by the session's URL, or empty if the entire directory is meant to be examined.

Get status as deeply as depth indicates. If depth is svn_depth_unknown, get the status down to the ambient depth of the working copy. If depth is deeper than the working copy, include changes that would be needed to populate the working copy to that depth.

The caller may not perform any RA operations using session before finishing the report, and may not perform any RA operations using session from within the editing operations of status_editor.

Use pool for memory allocation.

Note
  The reporter provided by this function does NOT supply copy- from information to the diff editor callbacks.
  In order to prevent pre-1.5 servers from doing more work than needed, and sending too much data back, a pre-1.5 'recurse' directive may be sent to the server, based on depth.

Ask the RA layer to update a working copy to a new revision.

The client initially provides an update_editor/update_baton to the RA layer; this editor contains knowledge of where the change will begin in the working copy (when `open_root()` is called).

In return, the client receives a reporter/report_baton. The client then describes its working copy by making calls into the reporter.

When finished, the client calls reporter->finish_report(). The RA layer then does a complete drive of update_editor, ending with update_editor->close_edit(), to update the working copy.

update_target is an optional single path component to restrict the scope of the update to just that entry (in the directory represented by the session's URL). If update_target is the empty string, the entire directory is updated.

Update the target only as deeply as depth indicates.

If send_copyfrom_args is TRUE, then ask the server to send copyfrom arguments to add_file() and add_directory() when possible. (Note: this means that any subsequent txdeltas coming from the server are presumed to apply against the copied file!)

Use ignore_ancestry to control whether or not items being updated will be checked for relatedness first. Unrelated items are typically transmitted to the editor as a deletion of one thing and the addition of another, but if this flag is `TRUE`, unrelated items will be diffed as if they were related.

The working copy will be updated to revision_to_update_to, or the "latest" revision if this arg is invalid.

The caller may not perform any RA operations using session before finishing the report, and may not perform any RA operations using session from within the editing operations of update_editor.

Allocate *reporter and *report_baton in result_pool. Use scratch_pool for temporary allocations.

Note
  The reporter provided by this function does NOT supply copy- from information to the diff editor callbacks.
  In order to prevent pre-1.5 servers from doing more work than needed, and sending too much data back, a pre-1.5 'recurse' directive may be sent to the server, based on depth.
  Pre Subversion 1.8 svnserve based servers never ignore ancestry.
  This differs from calling svn_ra_do_switch3() with the current URL of the target node. Update changes only the revision numbers, leaving any switched subtrees still switched, whereas switch changes every node in the tree to a child of the same URL.

Set *editor and *edit_baton to an editor for committing changes to the repository of session, setting the revision properties from revprop_table.

The revisions being committed against are passed to the editor functions, starting with the rev argument to `open_root`. The path root of the commit is the session's URL.

revprop_table is a hash mapping const char * property names to `svn_string_t` property values. The commit log message is expected to be in the `SVN_PROP_REVISION_LOG` element. revprop_table can not contain either of `SVN_PROP_REVISION_DATE` or `SVN_PROP_REVISION_AUTHOR`.

Before `close_edit` returns, but after the commit has succeeded, it will invoke commit_callback (if non-NULL) with filled-in svn_commit_info_t *, commit_baton, and pool or some subpool thereof as arguments. If commit_callback returns an error, that error will be returned from `*` close_edit, otherwise `close_edit` will return successfully (unless it encountered an error before invoking commit_callback).

The callback will not be called if the commit was a no-op (i.e. nothing was committed);

lock_tokens, if non-NULL, is a hash mapping const char * paths (relative to the URL of session) to const char * lock tokens. The server checks that the correct token is provided for each committed, locked path. lock_tokens must live during the whole commit operation.

If keep_locks is `TRUE`, then do not release locks on committed objects. Else, automatically release such locks.

The caller may not perform any RA operations using session before finishing the edit.

Use pool for memory allocation.

  New in 1.5.

Note
  Like most commit editors, the returned editor requires that the `copyfrom_path` parameter passed to its `add_file` and `add_directory` methods is a URL, not a relative path.

The keys of dirents will be entry names (const char *), and the values dirents (`svn_dirent_t` *). Use pool for all allocations.

dirent_fields controls which portions of the `svn_dirent_t` objects are filled in. To have them completely filled in just pass `SVN_DIRENT_ALL`, otherwise pass the bitwise OR of all the `SVN_DIRENT_` fields you would like to have returned to you.

path is interpreted relative to the URL in session.

If revision is `SVN_INVALID_REVNUM` (meaning 'head') and fetched_rev is not `NULL`, then this function will set *fetched_rev to the actual revision that was retrieved. (Some callers want to know, and some don't.)

If props is non `NULL`, set *props to contain the properties of the directory, including properties that are non-tweakable and generated by the SCM system itself (such as svn_prop_wc_kind and svn_prop_entry_kind properties). The keys are const char *, values are `svn_string_t` *.

Retrieve a subset of the interesting revisions of a file path as seen in revision end (see svn_fs_history_prev() for a definition of "interesting revisions").

Invoke handler with handler_baton as its first argument for each such revision. session is an open RA session. Use pool for all allocations.

If there is an interesting revision of the file that is less than or equal to start, the iteration will begin at that revision. Else, the iteration will begin at the first revision of the file in the repository, which has to be less than or equal to end. Note that if the function succeeds, handler will have been called at least once.

In a series of calls to handler, the file contents for the first interesting revision will be provided as a text delta against the empty file. In the following calls, the delta will be against the fulltext contents for the previous call.

If include_merged_revisions is TRUE, revisions which are included as a result of a merge between start and end will be included.

Note
  This functionality is not available in pre-1.1 servers. If the server doesn't implement it, an alternative (but much slower) implementation based on svn_ra_get_log2() is used.

On subversion 1.8 and newer servers this function has been enabled to support reversion of the revision range for include_merged_revision `FALSE` reporting by switching end with start.

Note
  Prior to Subversion 1.9, this function may request delta handlers from handler even for empty text deltas. Starting with 1.9, the delta handler / baton return arguments passed to handler will be NULL unless there is an actual difference in the file contents between the current and the previous call.

Invoke receiver with receiver_baton on each log message from start to end.

start may be greater or less than end; this just controls whether the log messages are processed in descending or ascending revision number order.

If start or end is `SVN_INVALID_REVNUM`, it defaults to youngest.

If paths is non-NULL and has one or more elements, then only show revisions in which at least one of paths was changed (i.e., if file, text or props changed; if dir, props changed or an entry was added or deleted). Each path is an const char *, relative to the repository root of session.

If limit is greater than zero only invoke receiver on the first limit logs.

If discover_changed_paths, then each call to receiver passes a const apr_hash_t * for the receiver's changed_paths argument; the hash's keys are all the paths committed in that revision, the hash's values are const svn_log_changed_path2_t * for each committed path. Otherwise, each call to receiver passes NULL for changed_paths.

If strict_node_history is set, copy history will not be traversed (if any exists) when harvesting the revision logs for each path.

If revprops is NULL, retrieve all revision properties; else, retrieve only the revision properties named by the (const char *) array elements (i.e. retrieve none if the array is empty).

If any invocation of receiver returns error, return that error immediately and without wrapping it.

If start or end is a non-existent revision, return the error `SVN_ERR_FS_NO_SUCH_REVISION`, without ever invoking receiver.

See also the documentation for `svn_log_message_receiver_t`.

The caller may not invoke any RA operations using session from within receiver.

Use pool for memory allocation.

Note
  If paths is NULL or empty, the result depends on the server. Pre-1.5 servers will send nothing; 1.5 servers will effectively perform the log operation on the root of the repository. This behavior may be changed in the future to ensure consistency across all pedigrees of server.
  Pre-1.5 servers do not support custom revprop retrieval; if revprops is NULL or contains a revprop other than svn:author, svn:date, or svn:log, an `SVN_ERR_RA_NOT_IMPLEMENTED` error is returned.

|  | svn_mergeinfo_inheritance_t | inherit,
|  | svn_boolean_t | include_descendants,
|  | apr_pool_t * | pool )

Set *catalog to a mergeinfo catalog for the paths in paths.

If no mergeinfo is available, set *catalog to `NULL`. The requested mergeinfo hashes are for paths (which are relative to session's URL) in revision. If one of the paths does not exist in that revision, return SVN_ERR_FS_NOT_FOUND.

inherit indicates whether explicit, explicit or inherited, or only inherited mergeinfo for paths is retrieved.

If include_descendants is TRUE, then additionally return the mergeinfo for any descendant of any element of paths which has the `SVN_PROP_MERGEINFO` property explicitly set on it. (Note that inheritance is only taken into account for the elements in paths; descendants of the elements in paths which get their mergeinfo via inheritance are not included in *catalog.)

Allocate the returned values in pool.

If revision is `SVN_INVALID_REVNUM`, it defaults to youngest.

If the server doesn't support retrieval of mergeinfo (which can happen even for file:// URLs, if the repository itself hasn't been upgraded), return `SVN_ERR_UNSUPPORTED_FEATURE` in preference to any other error that might otherwise be returned.

|  | apr_uint32_t | dirent_fields,
|  | svn_ra_dirent_receiver_t | receiver,
|  | void * | receiver_baton,
|  | apr_pool_t * | scratch_pool )

Efficiently list everything within a sub-tree.

Specify a glob pattern to search for specific files and folders.

In session, walk the sub-tree starting at path at revision down to the given depth. For each directory entry found, receiver will be called with receiver_baton. The starting path will be reported as well. Because retrieving elements of a svn_dirent_t can be expensive, you need to select them individually via flags set in dirent_fields.

patterns is an optional array of const char *. If it is not `NULL`, only those directory entries will be reported whose last path segment matches at least one of these patterns. This feature uses apr_fnmatch() for glob matching and requiring '.' to matched by dots in the path.

path must point to a directory and depth must be at least svn_depth_empty.

If the server doesn't support the 'list' command, return SVN_ERR_UNSUPPORTED_FEATURE in preference to any other error that might otherwise be returned.

Use scratch_pool for temporary memory allocation.

## svn_ra_local_init()

|  | svn_boolean_t | steal_lock,
|  | svn_ra_lock_callback_t | lock_func,
|  | void * | lock_baton,
|  | apr_pool_t * | pool )

Lock each path in path_revs, which is a hash whose keys are the paths to be locked, and whose values are the corresponding base revisions for each path.

The keys are (const char *) and the revisions are (svn_revnum_t *).

Note that locking is never anonymous, so any server implementing this function will have to "pull" a username from the client, if it hasn't done so already.

comment is optional: it's either an xml-escapable string which describes the lock, or it is NULL.

If any path is already locked by a different user, then call lock_func/lock_baton with an error. If steal_lock is TRUE, then "steal" the existing lock(s) anyway, even if the RA username does not match the current lock's owner. Delete any lock on the path, and unconditionally create a new lock.

For each path, if its base revision (in path_revs) is a valid revnum, then do an out-of-dateness check. If the revnum is less than the last-changed-revision of any path (or if a path doesn't exist in HEAD), call lock_func/lock_baton with an SVN_ERR_RA_OUT_OF_DATE error.

After successfully locking a file, lock_func is called with the lock_baton.

|  | void * | callback_baton,
|  | apr_hash_t * | config,
|  | apr_pool_t * | pool )

Open a repository access session to the repository at repos_URL, or inform the caller regarding a correct URL by which to access that repository.

If repos_URL can be used successfully to access the repository, set *session_p to an opaque object representing a repository session for the repository and (if corrected_url is non-NULL) set *corrected_url to NULL. If there's a better URL that the caller should try and corrected_url is non-NULL, set *session_p to NULL and *corrected_url to the corrected URL. If there's a better URL that the caller should try, and corrected_url is NULL, return an SVN_ERR_RA_SESSION_URL_MISMATCH error. Allocate all returned items in pool.

The repos_URL need not point to the root of the repository: subject to authorization, it may point to any path within the repository, even a path at which no node exists in the repository. The session will remember this URL as its "session URL" (also called "session root URL"), until changed by svn_ra_reparent(). Many RA functions take or return paths that are relative to the session URL.

If a corrected_url is returned, it will point to the same path within the new repository root URL that repos_URL pointed to within the old repository root URL.

If redirect_url is not NULL and a @corrected_url is returned, then redirect_url contains a non-canonicalized version of corrected_url, as communicated in the network protocol used by the RA provider. THe redirect_url should be used for to detect redirection loops. Canonicalization may change the protocol-level URL in a way that makes detection of redirect loops impossible in some cases since URLs which are different at the protocol layer could map to the same canonicalized URL.

Return `SVN_ERR_RA_UUID_MISMATCH` if uuid is non-NULL and not equal to the UUID of the repository at `repos_URL`.

callbacks/callback_baton is a table of callbacks provided by the client; see `svn_ra_callbacks2_t`.

config is a hash mapping const char * keys to `svn_config_t` * values. For example, the `svn_config_t` for the "~/.subversion/config" file is under the key "config". config may be NULL. This function examines some config settings under the "servers" key (if present) before loading the required RA module, and the RA module may also examine any config settings.

All RA requests require a session; they will continue to use pool for memory allocation.

Replay the changes from revision through editor and edit_baton.

Changes will be limited to those that occur under session's URL, and the server will assume that the client has no knowledge of revisions prior to low_water_mark. These two limiting factors define the portion of the tree that the server will assume the client already has knowledge of, and thus any copies of data from outside that part of the tree will be sent in their entirety, not as simple copies or deltas against a previous version.

Replay the changes from a range of revisions between start_revision and end_revision (inclusive).

When receiving information for one revision, a callback revstart_func is called; this callback will provide an editor and baton through which the revision will be replayed. When replaying the revision is finished, callback revfinish_func will be called so the editor can be closed.

Changes will be limited to those that occur under session's URL, and the server will assume that the client has no knowledge of revisions prior to low_water_mark.

Remove the repository lock for each path in path_tokens.

path_tokens is a hash whose keys are the paths to be locked, and whose values are the corresponding lock tokens for each path. If the path has no corresponding lock token, or if break_lock is TRUE, then the corresponding value shall be "".

Note that unlocking is never anonymous, so any server implementing this function will have to "pull" a username from the client, if it hasn't done so already.

If token points to a lock, but the RA username doesn't match the lock's owner, call lock_func/lock_baton with an error. If break_lock is TRUE, however, instead allow the lock to be "broken" by the RA user.
