the bottom of the active-directory stack was no longer
strictly necessary. This change removes that member and uses
the newer cwd_state parameter for the final restore_cwd.
(struct AD_ent) [u]: Remove now-unnecessary union.
[dev_ino]: Rename from `a'.
(AD_pop_and_chdir): Add a parameter to play the role of just-removed
bottom-of-stack cwd-state member.
(AD_pop_and_chdir): No longer return boolean. Adjust caller.
(AD_push_initial): Remove CWD parameter. Adjust caller.
|
|
(rm): Destroy the saved_cwd here (via cwd_state),
if necessary, not in remove_dir. Otherwise, removing multiple
`.'-relative nonempty directories no longer worked.

operating on too many command-line-specified nonempty directories.
(remove_dir): Destroy the `struct saved_cwd' on the
top of the stack before returning. This usually closes the file
descriptor that was used to return to the original working directory.

AD_push, prompt, remove_dir): Use bool when appropriate.
(top_dir, pop_dir, full_filename_):
Use size_t for sizes.

working directory, pretend we started from "/", not ".".
This avoids a bug on hosts like Solaris that don't let you
remove the working directory.
|

(top_dir): Remove now-unnecessary cast of obstack_base.
(pop_dir): Likewise.
(full_filename_): Likewise.

remove a symlink to a file on an off-line NFS-mounted partition.
Reported by David Howells in https://bugzilla.redhat.com/124699.
(write_protected_non_symlink): New function.
Don't invoke euidaccess on symlinks.
(prompt): Use write_protected_non_symlink rather than using
euidaccess directly, being careful not to call lstat twice for a file.

directory and with two or more command line arguments including an
absolute-named directory followed by a relative-named directory.
(struct cwd_state): Define.
(AD_pop_and_chdir): Redesign interface so that a restore_cwd failure
can be detected by the caller. Instead of returning a malloc'd
directory name, communicate it to caller via a new parameter, and
return an indication of whether restore_cwd failed. Update caller.
Eliminate an unnecessary call to AC_stack_top.
(remove_dir): Change type of cwd_state parameter to `struct cwd_state'
so we can now communicate to caller whether/how functions like
restore_cwd have failed. Update caller.
(rm_1): Fail if we've failed to restore the working directory
and the name of the next file to remove is `.'-relative.
(rm): Fail if the require_restore_cwd flag is true and we've
failed to restore the working directory.

per command line argument.

(remove_entry): Check for errno values like ENOENT
that show the file cannot be directory, instead of for errno
values like EPERM that show the file might be a directory. This
is necessary because, when a single unlink() call has multiple
reasons to fail, it can set errno to any of those reasons; it's
only the rare errno value like ENOENT that excludes all the other
possible reasons to fail even when the file is a directory.
(remove_cwd_entries): Don't attempt chdir if the file is known
to not be a directory.
(remove_dir): Use the same method that remove_cwd_entries uses
(for some reason they differed). Don't assert that saved_errno
must be EPERM; it might be just about anything.

Don't define. These symbols are no longer used.

adequate, since join.c uses alloca, yet lacked an in-file #pragma.
Remove `#pragma alloca'.

(IF_READDIR_NEEDS_REWINDDIR): Remove.
(remove_cwd_entries): Rewrite to avoid IF_READDIR_NEEDS_REWINDDIR,
which was a bit weird because it couldn't be emulated by a function.
|
|
(IF_READDIR_NEEDS_REWINDDIR): Define.
[! HAVE_WORKING_READDIR] (remove_cwd_entries): If readdir has just
returned NULL and there has been at least one successful unlink or
rmdir call since the opendir or previous rewinddir, then call
rewinddir and reiterate the loop.

(readdir_ignoring_dotdirs): New function.

clobber errno. Spotted by Arnold Robbins.

This avoids a warning from gcc on 64-bit systems.

with the above.

This fixes Debian bug# 178471.

Remove declaration of euidaccess.

has d_type == DT_UNKNOWN it may still be a directory -- or not (e.g., with
FreeBSD on an NFS-mounted file system), so resort to calling lstat to find out.

* src/remove.c: [cycle_check_state]: New global.
(remove_cwd_entries): Adapt to new semantics of cycle_check.
(rm): Call cycle_check_init and cycle_check_free for each file.
When rm detects a cycle, don't abort the entire command,
but rather just the affected command line argument.
* src/remove.c: Include <setjmp.h>
(struct dirstack_state) [current_arg_jumpbuf]: New member.
(remove_cwd_entries): Call longjmp if we detect a cycle.
(rm): Call setjmp here.
* src/remove.c (cycle_check, is_power_of_two): Remove functions.
Instead, include cycle-check.h and use it.
|
|
(full_filename_): When FILENAME is just `.'
and there is a nonempty directory-name part, don't append `/.'.
