Subject: [PATCH 1/5] Add a test which checks $CWD for find -execdir {} +/;

* find/testsuite/find.gnu/execdir-multiple.exp: New test; verifies
that for -execdir +, all the execs occur with the correct working
directory.
* find/testsuite/find.gnu/execdir-multiple.xo: Expected output for
this test.
* find/testsuite/Makefile.am (EXTRA_DIST_EXP): Add the new test.
(EXTRA_DIST_XO): Add the expected output file.
* find/testsuite/config/unix.exp (mkdir): Create proc "mkdir"
which creates a directory.
* find/testsuite/find.gnu/execdir-pwd1.exp: New test.
* find/testsuite/Makefile.am (EXTRA_DIST_EXP): Add
execdir-pwd1.exp.

Subject: [PATCH 3/5] Fix Savannah bug #19593, -execdir .... {} + has suboptimal performance

* find/ftsfind.c (consider_visiting): Don't call
complete_pending_execdirs for every file we visit.
(find): Instead, call complete_pending_execdirs every time we
see a file which isn't at the same nesting level as the previous
file we saw.  This is an improvement but not optimal (since
descending into a subdirectory will cause us to issue an exec
before we've finished with the current directory).
* NEWS: Mention this change.

+The find program will once again build argument lists longer than 1

From 93e76f306931097a28e2a5fe81bef03204d689d3 Mon Sep 17 00:00:00 2001
From: Kamil Dudka <kdudka@...>
Date: Mon, 10 May 2010 16:11:41 +0200
Subject: [PATCH 2/5] Exec predicates now store which directory they want to run in.

* lib/dircallback.c (run_in_dirfd): New name for old run_in_dir
function.
(run_in_dir): Like the old function 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 function; true for predicates -execdir
and -okdir.
* find/pred.c: Include 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 declaration of global variable.
(starting_desc): Remove declaration of global variable.
* import-gnulib.config (modules): Import module save-cwd.

From 556abd539c0708d9bc2cb1e25872664c17b1a2aa Mon Sep 17 00:00:00 2001
From: Kamil Dudka <kdudka@...>
Date: Mon, 10 May 2010 16:22:44 +0200
Subject: [PATCH 4/5] Fix Savannah bug #27563, -L breaks -execdir.

* find/pred.c (mdir_name): New function, taken from newer gnulib.
(initialise_wd_for_exec): New function, factoring out part of the body
of record_exec_dir.
(record_exec_dir): If state.rel_pathname contains a /, extract the
directory part and initialise execp->wd_for_exec to point at that
directory.
(impl_pred_exec): Rename new_impl_pred_exec to impl_pred_exec.
Drop the prefix and pfxlen parameters.  Compute the base name of
the target and pass that to the bc_push_arg function instead of
state.rel_pathname.  Deal with state.rel_pathname being an
absolute path (e.g. find / -execdir...).  Introduce a new
variable, result, allowing us to free the buffer used for the base
name in the return path.
(pred_exec): Don't pass the prefix and the prefix length any more.
(pred_execdir): Likewise.
(pred_ok): Likewise.
(pred_okdir): Likewise.

Thanks for working on this.

Unfortunately I think something went a little wrong with the rebase
(or whatever you did).   When I apply your patches against
rel-4-4-fixes (a242875ae63167ee29c3f626741c56266be3bc92) and do "make
distcheck" I get this output:

Sorry for not catching this.  Unfortunately 'make distcheck' does not work

My mistake, it looks like I got confused by the following commit:

http://git.savannah.gnu.org/gitweb/?p=findutils.git;a=commitdiff;h=aec54f2317440454a57580309c32de1dde62259c

So the NEWS entries should be appended to 4.4.3-git, right?

> Could you take another look, please?

Sure, I try to get these things working tomorrow or so.

Oh, oops.    I didn't realise it started out broken!

Yes, the attached patch is the actual fixup I used.

Perhaps my mistake as well.  It seems like I have to run 'make' before
'make distcheck' to get it passed.

The revisited patches are attached.  I've tried 'make distcheck' after
application of each individual patch.  All of them passed.  Please let
me know if there are still some outstanding issues.

From: Kamil Dudka <kdudka@...>
Date: Tue, 18 May 2010 12:58:34 +0200
Subject: [PATCH 2/5] Exec predicates now store which directory they want to run in.

* lib/dircallback.c (run_in_dirfd): New name for old run_in_dir
function.
(run_in_dir): Like the old function 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 function; true for predicates -execdir
and -okdir.
* find/pred.c: Include 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 declaration of global variable.
(starting_desc): Remove declaration of global variable.
* import-gnulib.config (modules): Import module save-cwd.

+ Exec predicates now store which directory they want to run in.
+ * lib/dircallback.c (run_in_dirfd): New name for old run_in_dir
+ function.
+ (run_in_dir): Like the old function 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 function; true for predicates -execdir
+ and -okdir.
+ * find/pred.c: Include 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 declaration of global variable.
+ (starting_desc): Remove declaration of global variable.
+ * import-gnulib.config (modules): Import module save-cwd.
+
  Add a test which checks $CWD for find -execdir {} +/;
  * find/testsuite/find.gnu/execdir-multiple.exp: New test; verifies
  that for -execdir +, all the execs occur with the correct working

complete_pending_execdirs for every file we visit.
(find): Instead, call complete_pending_execdirs every time we
see a file which isn't at the same nesting level as the previous
file we saw.  This is an improvement but not optimal (since
descending into a subdirectory will cause us to issue an exec
before we've finished with the current directory).

+** Performance changes
+
+The find program will once again build argument lists longer than 1
+with "-execdir ...+".  The upper limit of 1 argument for execdir was
+introduced as a workaround in findutils-4.3.4.   The limit is now
+removed, but find still does not issue the maximum possible number of
+arguments, since an exec will occur each time find encounters a
+subdirectory (if at least one argument is pending).

[James Youngman-5]

(resending, this time omitting the large patch with the .po file changes)

I noticed today I had not done this.   Sorry!

I needed to add an extra few patches to:
- update the version of gnulib and fix a dependency problem
- fix the declaration of run_in_dir
- temporarily move a pre-existing local change to make the patch easier to apply

I have attached the additional changes I made.   They're all pushed to
the git repository already.

Thanks again!
James.

James, I really appreciate your patience.  I've re-tested the current HEAD
of the rel-4-4-fixes branch and all works as expected.  Thanks!
