 * @brief Subversion's working copy library
 *
 * Requires:
 *            - A working copy
 *
 * Provides:
 *            - Ability to manipulate working copy's versioned data.
 *            - Ability to manipulate working copy's administrative files.
 *
 * Used By:
 *            - Clients.
 *
 * Notes:
 *            The 'path' parameters to most of the older functions can be
 *            absolute or relative (relative to current working
 *            directory).  If there are any cases where they are
 *            relative to the path associated with the
 *            'svn_wc_adm_access_t *adm_access' baton passed along with the
 *            path, those cases should be explicitly documented, and if they
 *            are not, please fix it. All new functions introduced since
 *            Subversion 1.7 require absolute paths, unless explicitly
 *            documented otherwise.
 *
 *            Starting with Subversion 1.7, several arguments are re-ordered
 *            to be more consistent through the api. The common ordering used
 *            is:
 *
 *            Firsts:
 *              - Output arguments
 *            Then:
 *              - Working copy context
 *              - Local abspath
 *            Followed by:
 *              - Function specific arguments
 *              - Specific callbacks with their batons
 *            Finally:
 *              - Generic callbacks (with baton) from directly functional to
 *                just observing:
 *                  - svn_wc_conflict_resolver_func2_t
 *                  - svn_wc_external_update_t
 *                  - svn_cancel_func_t
 *                  - svn_wc_notify_func2_t
 *              - Result pool
 *              - Scratch pool.

/**
 * Interactive conflict handling
 *
 * @defgroup svn_wc_conflict Conflict callback functionality
 * @{
 *
 * 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 (@c
 * 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 @c merged_file in-place
 *
 *        or, if libsvn_wc never supplied a merged_file in the
 *        description structure (i.e. passed NULL for that field),
 *
 *    - return the merged file in the #svn_wc_conflict_result_t.

 * for getting the status of exactly one thing, another for
 * getting the statuses of (potentially) multiple things and a third for
 * getting the working copy out-of-dateness with respect to the repository.
 *
 * Why do we have two different functions for getting working copy status?
 * The concept of depth, as explained in the documentation for
 * svn_depth_t, may be useful in understanding this.  Suppose we're
 * getting the status of directory D:
 *
 * To offer all three levels, we could have one unified function,
 * taking a `depth' parameter.  Unfortunately, because this function
 * would have to handle multiple return values as well as the single
 * return value case, getting the status of just one entity would
 * become cumbersome: you'd have to roll through a hash to find one
 * lone status.
 *
 * So we have svn_wc_status3() for depth-empty (just D itself), and
 * svn_wc_walk_status() for depth-immediates and depth-infinity,
 * since the latter two involve multiple return values. And for
 * out-of-dateness information we have svn_wc_get_status_editor5().

/**
 * Do a depth-first crawl in a working copy, beginning at @a local_abspath,
 * using @a wc_ctx for accessing the working copy.
 *
 * Communicate the `state' of the working copy's revisions and depths
 * to @a reporter/@a report_baton.  Obviously, if @a local_abspath is a
 * file instead of a directory, this depth-first crawl will be a short one.
 *
 * No locks or logs are created, nor are any animals harmed in the
 * process unless @a restore_files is TRUE.  No cleanup is necessary.
 *
 * After all revisions are reported, @a reporter->finish_report() is
 * called, which immediately causes the RA layer to update the working
 * copy.  Thus the return value may very well reflect the result of
 * the update!
 *
 * If @a depth is #svn_depth_empty, then report state only for
 * @a path itself.  If #svn_depth_files, do the same and include
 * immediate file children of @a path.  If #svn_depth_immediates,
 * then behave as if for #svn_depth_files but also report the
 * property states of immediate subdirectories.  If @a depth is
 * #svn_depth_infinity, then report state fully recursively.  All
 * descents are only as deep as @a path's own depth permits, of
 * course.  If @a depth is #svn_depth_unknown, then just use
 * #svn_depth_infinity, which in practice means depth of @a path.
 *
 * Iff @a honor_depth_exclude is TRUE, the crawler will report paths
 * whose ambient depth is #svn_depth_exclude as being excluded, and
 * thus prevent the server from pushing update data for those paths;
 * therefore, don't set this flag if you wish to pull in excluded paths.
 * Note that #svn_depth_exclude on the target @a path is never
 * honored, even if @a honor_depth_exclude is TRUE, because we need to
 * be able to explicitly pull in a target.  For example, if this is
 * the working copy...
 *
 *    svn co greek_tree_repos wc_dir
 *    svn up --set-depth exclude wc_dir/A/B/E  # now A/B/E is excluded
 *
 * ...then 'svn up wc_dir/A/B' would report E as excluded (assuming
 * @a honor_depth_exclude is TRUE), but 'svn up wc_dir/A/B/E' would
 * not, because the latter is trying to explicitly pull in E.  In
 * general, we never report the update target as excluded.
 *
 * Iff @a depth_compatibility_trick is TRUE, then set the @c start_empty
 * flag on @a reporter->set_path() and @a reporter->link_path() calls
 * as necessary to trick a pre-1.5 (i.e., depth-unaware) server into
 * sending back all the items the client might need to upgrade a
 * working copy from a shallower depth to a deeper one.
 *
 * If @a restore_files is TRUE, then unexpectedly missing working files
 * will be restored from the administrative directory's cache. For each
 * file restored, the @a notify_func function will be called with the
 * @a notify_baton and the path of the restored file. @a notify_func may
 * be @c NULL if this notification is not required.  If @a
 * use_commit_times is TRUE, then set restored files' timestamps to
 * their last-commit-times.  For working copies that do not store local
 * pristine contents for all files, return @c SVN_ERR_WC_PRISTINE_DEHYDRATED
 * on an attempt to restore a file whose pristine contents is not present
 * locally.
 *
 * @note This is a relatively low-level function operating directly on a
 * working copy, so a caller is expected to be able to handle working copies
 * that do not store local copies of all pristine contents.  This can be
 * achieved by synchronizing the text-base state before and optionally
 * after the function call.  @see svn_wc_textbase_sync().

 * Set @a *editor and @a *edit_baton to an editor and baton for updating a
 * working copy.
 *
 * @a anchor_abspath is a local working copy directory, with a fully recursive
 * write lock in @a wc_ctx, which will be used as the root of our editor.
 *
 * @a target_basename is the entry in @a anchor_abspath that will actually be
 * updated, or the empty string if all of @a anchor_abspath should be updated.
 *
 * The editor invokes @a notify_func with @a notify_baton as the update
 * progresses, if @a notify_func is non-NULL.
 *
 * If @a cancel_func is non-NULL, the editor will invoke @a cancel_func with
 * @a cancel_baton as the update progresses to see if it should continue.
 *
 * If @a conflict_func is non-NULL, then invoke it with @a
 * conflict_baton whenever a conflict is encountered, giving the
 * callback a chance to resolve the conflict before the editor takes
 * more drastic measures (such as marking a file conflicted, or
 * bailing out of the update).
 *
 * If @a external_func is non-NULL, then invoke it with @a external_baton
 * whenever external changes are encountered, giving the callback a chance
 * to store the external information for processing.
 *
 * If @a diff3_cmd is non-NULL, then use it as the diff3 command for
 * any merging; otherwise, use the built-in merge code.
 *
 * @a preserved_exts is an array of filename patterns which, when
 * matched against the extensions of versioned files, determine for
 * which such files any related generated conflict files will preserve
 * the original file's extension as their own.  If a file's extension
 * does not match any of the patterns in @a preserved_exts (which is
 * certainly the case if @a preserved_exts is @c NULL or empty),
 * generated conflict files will carry Subversion's custom extensions.
 *
 * @a target_revision is a pointer to a revision location which, after
 * successful completion of the drive of this editor, will be
 * populated with the revision to which the working copy was updated.
 *
 * If @a use_commit_times is TRUE, then all edited/added files will
 * have their working timestamp set to the last-committed-time.  If
 * FALSE, the working files will be touched with the 'now' time.
 *
 * If @a allow_unver_obstructions is TRUE, then allow unversioned
 * obstructions when adding a path.
 *
 * If @a adds_as_modification is TRUE, a local addition at the same path
 * as an incoming addition of the same node kind results in a normal node
 * with a possible local modification, instead of a tree conflict.
 *
 * If @a depth is #svn_depth_infinity, update fully recursively.
 * Else if it is #svn_depth_immediates, update the uppermost
 * directory, its file entries, and the presence or absence of
 * subdirectories (but do not descend into the subdirectories).
 * Else if it is #svn_depth_files, update the uppermost directory
 * and its immediate file entries, but not subdirectories.
 * Else if it is #svn_depth_empty, update exactly the uppermost
 * target, and don't touch its entries.
 *
 * If @a depth_is_sticky is set and @a depth is not
 * #svn_depth_unknown, then in addition to updating PATHS, also set
 * their sticky ambient depth value to @a depth.
 *
 * If @a server_performs_filtering is TRUE, assume that the server handles
 * the ambient depth filtering, so this doesn't have to be handled in the
 * editor.
 *
 * If @a clean_checkout is TRUE, assume that we are checking out into an
 * empty directory, and so bypass a number of conflict checks that are
 * unnecessary in this case.
 *
 * If @a fetch_dirents_func is not NULL, the update editor may call this
 * callback, when asked to perform a depth restricted update. It will do this
 * before returning the editor to allow using the primary ra session for this.

 *
 * @a ignore_ancestry determines whether paths that have discontinuous node
 * ancestry are treated as delete/add or as simple modifications.  If
 * @a ignore_ancestry is @c FALSE, then any discontinuous node ancestry will
 * result in the diff given as a full delete followed by an add.
 *
 * @a show_copies_as_adds determines whether paths added with history will
 * appear as a diff against their copy source, or whether such paths will
 * appear as if they were newly added in their entirety.
 *
 * If @a use_git_diff_format is TRUE, copied paths will be treated as added
 * if they weren't modified after being copied. This allows the callbacks
 * to generate appropriate --git diff headers for such files.

 * #SVN_ERR_CANCELLED), return that error immediately.
 *
 * For working copies that do not store local pristine contents for all

 *
 * @note For general purposes, please consider using APIs from svn_client.h,

 * Furthermore, merging into an unversioned file is a lossy operation.)

 *
 * If @a merge_props_state is non-NULL, merge @a prop_diff into the
 * working properties before merging the text.  (If @a merge_props_state
 * is NULL, do not merge any property changes; in this case, @a prop_diff
 * is only used to help determine the text merge result.)  Handle any

 * The outcome of the text merge is returned in @a *merge_content_outcome. If
 * there is a conflict and @a dry_run is @c FALSE, then attempt to call @a
 * conflict_func with @a conflict_baton (if non-NULL).  If the
 * conflict callback cannot resolve the conflict, then:
 *
 *   * Put conflict markers around the conflicting regions in
 *     @a target_abspath, labeled with @a left_label, @a right_label, and
 *     @a target_label.  (If any of these labels are @c NULL, default
 *     values will be used.)
 *
 *   * Copy @a left_abspath, @a right_abspath, and the original @a
 *     target_abspath to unique names in the same directory as @a
 *     target_abspath, ending with the suffixes ".LEFT_LABEL", ".RIGHT_LABEL",
 *     and ".TARGET_LABEL" respectively.
 *
 *   * Mark @a target_abspath as "text-conflicted", and track the above
 *     mentioned backup files as well.
 *
 *   * If @a left_version and/or @a right_version are not NULL, provide

 *  @a right_abspath are created next to it using @a left_label and
 *  @a right_label. @a target_abspath is marked as "text-conflicted", and
 *  begins tracking the two backup files and the version information.
 *
 * If @a dry_run is @c TRUE no files are changed.  The outcome of the merge

 *
 * ### For text, we report the outcome as 'merged' if there was some
 *     incoming change that we dealt with (even if we decided to no-op?)
 *     but the callers then convert this outcome into a notification
 *     of 'merged' only if there was already a local modification;
 *     otherwise they notify it as simply 'updated'.  But for props
 *     we report a notify state of 'merged' here if there was an
 *     incoming change regardless of the local-mod state.  Inconsistent.
 *
 * Use @a scratch_pool for any temporary allocation.
 *
 * For working copies that do not store local pristine contents for all
 * files, return @c SVN_ERR_WC_PRISTINE_DEHYDRATED on an attempt to merge
 * a file whose pristine contents is not present locally.
 *
 * @note This is a relatively low-level function operating directly on a
 * working copy, so a caller is expected to be able to handle working copies
