* lib/dircallback.c (run_in_dirfd): New name for old run_in_dir function. (run_in_dir): Like the old funciton of the same name, but now takes an argument const struct saved_cwd *. * lib/dircallback.h: Update declarations of run_in_dirfd and run_in_dir. * find/util.c: Include dircallback.h, xalloc.h, save-cwd.h. (do_complete_pending_execdirs): Remove dir_fd parameter, since the per-predicate data structures now indicate what directory they need to be run in. Instead of calling bc_do_exec directly, use a callback 'exec_cb' that uses run_in_dir (which now takes a saved_cwd* parameter instead of a file descriptor). (do_exec): Called by do_complete_pending_execdirs, and simply uses run_in_dir to call exec_cb, restoring the working directory afterward. (record_initial_cwd): New function, initialises the global variable initial_wd. (cleanup_initial_cwd): New function, cleans up the global variable initial_wd. (cleanup): Call cleanup_initial_cwd. (get_start_dirfd): Remove. (is_exec_in_local_dir): New funciton; true for predicates -execdir and -okdir. * find/pred.c: Include cloexec.h and save-cwd.h. (record_exec_dir): New function, sets the value of execp->wd_for_exec if needed. (new_impl_pred_exec): Remove the obsolete dir_fd parameter. Call record_exec_dir. (pred_exec): Don't pass the dir_fd parameter. (pred_execdir): Likewise. (pred_ok): Likewise. (pred_okdir): Likewise. (can_access): Call run_in_dirfd rather than run_in_dir (the function was renamed). (prep_child_for_exec): Remove dir_fd parameter; don't fchdir to that. Call restore_cwd instead (passing a saved_cwd* parameter which replaced dir_fd). (launch): Remove references to execp->use_current_dir. (launch): Change references to execp->dir_fd to execp->wd_for_exec. * find/parser.c: Correct indentiation of declaration of insert_exec_ok and remove the obsolete dir_fd parameter. (parse_exec): Don't pass the dir_fd parameter to insert_exec_ok. (parse_execdir): Likewise. (parse_ok): Likewise. (parse_okdir): Likewise. (insert_exec_ok): Remove obsolete dir_fd paramter. Initialise execp->wd_for_exec, either to NULL (for -*dir) or to the initial_wd. * find/ftsfind.c: Remove get_current_dirfd. Remove complete_execdirs_cb. (consider_visiting): Call complete_pending_execdirs directly. (main): Call record_initial_cwd to record the initial working directory, early on. Don't initialise starting_dir or starting_desc, they have been removed. * find/finddata.c: Include save-cwd.h. Remove starting_dir and starting_desc. Add new global variable initial_wd. It is a struct saved_wd* and represents find's initial working directory. * find/find.c: Include save-cwd.h. (main): Call record_initial_cwd in order to initialise the global variable initial_wd Don't set starting_desc and starting_dir, since those variables have been removed. (safely_chdir): Don't pass an fd to complete_pending_execdirs. (chdir_back): Remove the safety check (since we are using fchdir and in any case no longer have all the data that the existing wd_sanity_check function wants). (do_process_top_dir): Don't pass an fd to complete_pending_execdirs. (process_dir): Likewise. * find/defs.h (struct exec_val): Remove use_current_dir and dir_fd. Replace with wd_for_exec, which is a struct saved_wd*. (get_start_dirfd): Remove prototype. (get_current_dirfd): Remove prototype. (complete_pending_execdirs): No longer takes dir_fd parameter. (record_initial_cwd): Add prototype. (is_exec_in_local_dir): Add prototype. (options): Declare. (initial_wd): Add declaration. It is a struct saved_wd* and represents find's initial working directory. (starting_dir): Remove devlaration of global variable. (starting_desc): Remove devlaration of global variable. * import-gnulib.config (modules): Import module save-cwd. Signed-off-by: James Youngman <jay@gnu.org>
This package contains the GNU find, xargs, and locate programs. find and xargs comply with POSIX 1003.2, as far as I know (with the exception of the "+" modifier for the "-exec" action, which isn't implemented yet). They also support a large number of additional options, some borrowed from Unix and some unique to GNU. See the file NEWS for a list of major changes in the current release. See the file INSTALL for compilation and installation instructions. To verify the GPG signature of the release, you will need the public key of the findutils maintainer. You can download this from ftp://ftp.gnu.org/gnu/gnu-keyring.gpg. Alternatively, you could query a PGP keyserver, but you will need to use one that can cope with subkeys containing photos. Many older key servers cannot do this. I use subkeys.pgp.net. I think that one works. See also the "Downloading" section of http://www.gnu.org/software/findutils/. Special configure options: --with-afs Make find support "-fstype afs". Requires /afs, /usr/afsws/lib, and /usr/afsws/include. configure doesn't add AFS support automatically because it adds considerably to find's size, and the AFS libraries need -lucb on Solaris, which breaks find. --enable-id-cache Make tables of used UIDs and GIDs at startup instead of using getpwuid or getgrgid when needed. Speeds up -nouser and -nogroup unless you are running NIS or Hesiod, which make password and group calls very expensive. --enable-debug Produce output on the standard error output indicating what find is doing. This information includes details about how the command line has been parsed and what files have been stat()ed. This output is normally interesting only to the maintainer, and so is off by default. DEFAULT_ARG_SIZE=<value> If this environment variable is defined to a numeric expression during configure, it determines the default argument size limits used by xargs without -s, and by find, when spawning child processes. Otherwise, the default is set at 128 kibibytes. If the system cannot support the default limit, the system's limit will be used instead. To gain speed, GNU find avoids statting files whenever possible. It does this by: 1. Checking the number of links to directories and not statting files that it knows aren't directories until it encounters a test or action that needs the stat info. 2. Rearranging the command line, where possible, so that it can do tests that don't require a stat before tests that do, in hopes that the latter will be skipped because of an OR or AND. (But it only does this where it will leave the output unchanged.) The locate program and its helper programs are derived (heavily modified) from James Woods' public domain fast-find code, which is also distributed with the 4.3BSD find. Because POSIX.2 requires `find foo' to have the same effect as `find foo -print', the fast-find searching has been moved to a separate program, `locate'; the same thing has been done in 4.4BSD. If you use locate, you should run the included `updatedb' script from cron periodically (typically nightly). Mail suggestions and bug reports for these programs to bug-findutils@gnu.org.
