+
+ * fts.c: Don't include "cycle-check.h" or "hash.h".
+ (setup_dir, free_dir): New functions.
+ (enter_dir, leave_dir): Define trivial
+ alternatives of _LGPL_PACKAGE. Move to fts-cycle.c if !_LGPL_PACKAGE.
+ (HT_INITIAL_SIZE, ENTER_DIR): Remove. All uses removed.
+ (LEAVE_DIR): Fix typo: pass Fts and Ent to leave_dir.
+ (struct Active_dir, AD_compare, AD_hash, enter_dir, leave_dir):
+ Move to fts-cycle.c.
+ (fts_open): Use setup_dir.
+ (fts_close): Use free_dir.
+ (fts_read): Have just one copy of the ENTER_DIR code rather than three.
+ This adds a label and some gotos, but the alternatives were messier.
+ Check for memory allocation failure when entering a dir.
+ (fts_stat) [_LGPL_PACKAGE]: Bring back glibc cycle detection code.
+ * fts_.h (_LGPL_PACKAGE) [defined _LIBC]: New macro.
+ (FTS): New member fts_cycle, that is a union that contains the
+ old active_dir_ht and cycle_state. All uses changed to mention
+ fts_cycle.ht and fts_cycle.state.
+ * fts-cycle.c: New file, containing GPL'ed code migrated out of
+ fts.c, with the following changes:
+ (setup_dir, free_dir): New functions.
+ (enter_dir): Now returns bool. Return true if successful, false
+ if memory exhausted. All callers changed.
+ Do not bother partly cleaning up on
+ memory allocation failure; that is free_dir's job.
+ However, free ad if hash_insert fails, to avoid memory leak.
+ (enter_dir, leave_dir): Accommodate change to FTS by inspecting
+ fts->fts_options to see which union member to use.

* fts.c (fts_open): Remove useless but otherwise harmless malloc call.
