* src/df.c (alloc_table_row): Use the size of char** to enlarge
the table. Spotted by Coverity.
|
|
* src/df.c (usage): Adjust the --human and --si descriptions
to not depend on each other. Also include an example that is
illustrative of the rounding, suffix, width, and localized fractions.
* src/system.h (emit_size_note). Adjust so that it's obvious the
description is pertaining to the input SIZE argument, and not
to any sizes that might be output by df for example.

Run "make update-copyright", but then also run this,
perl -pi -e 's/2\d\d\d-//' tests/sample-test
to make that one script use the single most recent year number.

* src/df.c (get_disk): Use the same heuristic used in
get_point() to select the shortest file system mount point,
in an attempt to show the base mounted file system.
* NEWS: Mention the bug fix.

This is so the matching for the device is done on the canonical name
of the disk node, rather than on the path of the symlink.
In any case the user will generally want to use the symlink target.
* src/df.c (get_disk): Canonicalize the passed file,
before matching against the list of mounted file system devices.
Note we pass the original symlink name to the "file" output field,
as the symlink target is usually available through the "source" field.
* tests/df/df-symlink.sh: Test the dereferencing operation.
* tests/local.mk: Mention the new test.
* NEWS: Mention the fix.

Add a new rule to ensure the use of quote() instead of '%s' or `%s'
in format strings of diagnostics messages.
* cfg.mk (sc_prohibit_quotes_notation): Add rule.
* TODO: Remove the entry regarding the '%s' notation.
* src/mkfifo.c (main): Remove the offending and in this case even
duplicate quoting in the format string of the error diagnostic.
* src/mknod.c (main): Likewise.
* src/df.c (decode_output_arg): Change two invocations of error()
according to the above new rule.
* src/numfmt.c: Fix numerous wrong quote notations to fit the above
new rule, mostly in internal debugging diagnostic messages.

Avoid Valgrind reports of "definitely lost" items
and while at it, free all discarded mount entries
to minimize the amount of memory used.
* src/df.c (filter_mount_list): Use the newly exported
free_mount_entry() from gnulib to free all mount entries
as they're discarded.

gotten quite out of line in a couple of places.
|
|
* src/df.c (filter_mount_list): Initialize devlist->dev_num correctly
when unable to stat() a mount point. This will avoid possible invalid
deduplication done on the list due to use of uninitialized memory.

Also refactor the test to be table driven.
* NEWS: Mention the bug fix.

Like any other pseudo file system, df should show rootfs only
when the -a option is specified, i.e. specifying -trootfs alone
is not sufficient. As the rootfs entry is now elided by the
general deduplication in filter_mount_list (commit v8.20-103-gbb116d3),
all other references to rootfs can be removed again.
* src/df.c (show_rootfs): Remove global variable.
(ROOTFS): Remove constant.
(filter_mount_list): Remove case to handle rootfs specially.
(main): In the case for handling the -t option, remove setting
of the show_rootfs variable.
* tests/df/skip-rootfs.sh: Adapt the test case "df -t rootfs":
the rootfs file system must not be printed (because no -a).
* doc/coreutils.texi (df invocation): Correct the documentation
about eliding mount entries: it is not the first occurrence of
the the device which wins, but now rather the entry with the
shortest mount point name. Also adapt the description about
eliding pseudo file system types like rootfs.
* NEWS (Changes in behavior): Adapt entry.
|
|
* src/df.c (struct devlist): Add a new element for storing
pointers to mount_entry structures.
(devlist_head, dev_examined): Remove.
(filter_mount_list): Add new function to filter out the rootfs
entry (unless -trootfs is specified), and duplicities. The
function favors entries with a '/' character in me_devname
or those with the shortest me_mountdir string, if multiple
entries fulfill the first condition.
Use struct devlist to build up a list of entries already known,
and finally rebuild the global mount_list.
(get_all_entries): Call the above new function unless the -a
option is specified.
(get_dev): Remove the code for skipping rootfs and duplicities.
* tests/df/skip-duplicates.sh: Add test cases.

Each program with at least one long option which is marked as
'required_argument' and which has also a short option for that
option, should print a note about mandatory arguments.

As the inodes information is usually not so much of interest,
and some file systems including btrfs do not even provide it,
reading of the full df --output is easier when the block
statistic fields come just left of the last field, the mount
point.
* src/df.c (all_args_string): Move the inodes fields before
the block fields.
(usage): Likewise.
* tests/df/df-output.sh: Likewise.
* doc/coreutils.texi (df invocation): Likewise. Additionally,
explicitly mention the default order of the --output option.
|
|
* src/df.c (usage): Add a short description of --output and its
available field names for use in the optional argument.
* doc/coreutils.texi (df invocation): Add the new option with more
details and a few examples.
* NEWS (New features): Mention the new option.
(Changes in behvaior): Mention the new placeholder for fields
in the "total" line.

This supports changing the order of the fields displayed,
and also allows the simultaneous display of inode and block fields.
src/df.c (get_dev): Factor out calling get_header to ...
(main): ... here. Call print_table only if file_systems_processed.
src/df.c (Displayable fields): Rename DEV_FIELD to SOURCE_FIELD.
Rename TYPE_FIELD to FSTYPE_FIELD. Rename FREE_FIELD to AVAIL_FIELD.
Rename MNT_FIELD to TARGET_FIELD.
* src/df.c (display_field_t): Turn loose enum definition of the
displayable fields into a typedef. Add the inode fields ITOTAL_FIELD,
IUSED_FIELD, IAVAIL_FIELD, IPCENT_FIELD.
(field_data_t): Define structure to hold the display field, the
caption, the width and the alignment for each field of the above
type.
(field_data): Add array the values of field data for each display
field.
(headers, alignments, widths): Remove arrays.
(columns): Add a pointer to the storage for the array of the actual
output columns, i.e., fields.
(ncolumns): Add counter for the current output columns.
(alloc_table_row): Allocate the dynamic ncolumns value of strings.
(print_table): Loop over ncolumns instead of constant NFIELDS. Rename
loop variable 'field' to 'col' to avoid ambiguity with the 'field'
element in the columns structure. Adjust the condition for printing
the last column by comparing with the column number instead of the
field name (TARGET_FIELD). Use the width and the alignment stored in
the columns data.
(alloc_field): Add new function to allocate a field in the columns
array.
(get_field_list): Add new function to fill the array of output columns
for each mode.
(get_header): Loop over ncolumns instead of constant NFIELDS. Rename
the loop variable 'field' to 'col' to avoid ambiguity with the 'field'
element in the columns structure. Remove the code for continuing the
loop if the current column is the file system type and print_type is not
active (which is now impossible). Store the cell in the columns store
along with the new width.
(get_dev): Loop over ncolumns instead of the constant NFIELDS. Rename
the loop variable 'field' to 'col' to avoid ambiguity with the 'field'
element in the columns structure; move the definition down to where it
is used first. Add cases for the inode fields ITOTAL_FIELD,
IUSED_FIELD, IAVAIL_FIELD and IPCENT_FIELD. Store the cell in the
columns store along with the new width.
(main): Use new get_field_list function to fill the list of output
columns.
* src/df.c (print_table): Instead of fputs()ing directly, apply
ambsalign on the last field, too. Use the new MBA_NO_RIGHT_PAD flag
for this.
* src/df.c (TOTAL_OPTION): Add new enum value.
(long_options): Use it for the "total" option instead of 'c'.
(main): Likewise.
* src/df.c (get_dev): Remove condition to copy the fstype into the
FSTYPE_FIELD - based on whether print_type is non-Null. Since the
introduction of get_field_list(), there are only fields added to
the columns array which have to be added.
* src/df.c (get_dev): Guard the summing up of the values for the
grand total: only do it if we have to print the total and if the
current invocation is not for processing it.
* src/df.c (main): Pass a hyphen "-" for the mount point name
to get_dev.
(get_dev): As the mount_point is now always there,
remove the condition and the else case for the TARGET_FIELD.
Instead, simply copy the mount_point.
All cells are now always present. Therefore, add an assertion
statement if one was not. Furthermore, hide the problematic
characters unconditionally.
(print_table): Remove the skipping of empty cells.
* tests/df/total-verify.sh: Accommodate to the new "-" in the
target field of the summary line.
* NEWS: Mention the change in behavior.
* src/df.c (field_type_t): Add new typedef of 3 enums to distinguish
between block, inode and other fields.
(field_data_t): Add field_type member of the above new type.
(field_data): Add default values for the above field_type,
indicating whether a field contains block values, inode values
or other, generic values.
(field_values_t): Add this struct to store the field values, used
by and factored out from get_dev to be able to define such a struct
for both the inode and the block values.
(get_field_values): Add this function to obtain the block values
and the inode values from the file system usage, used by and
factored out from get_dev.
(add_to_grand_total): Add this function to sum the values of the
current mount point up for the grand total, used by and factored
out from get_dev.
(get_dev): Move the definition of the variables fsu, buf, pct and
cell down to where they are used first to give them a better scope.
Factor out input_units, output_units, total, available,
negate_available, available_to_root, used and negate_used into the
above struct field_values_t.
Factor out the mapping of the fsu values to the above variables
into above function get_field_values.
Factor out the summing up of the grand total values into the
above function add_to_grand_total.
Define block_values and inode_values of the new type and call the
new get_field_values to fill them from the fsu values.
Call the above function add_to_grand_total for summing up the
values for the grand total.
Inside the loop over all fields, define a variable 'v' to point
to either the block_values or the inode_values, depending on the
current field's field_type. Change the code in the cases
TOTAL_FIELD/ITOTAL_FIELD, USED_FIELD/IUSED_FIELD, AVAIL_FIELD/
IAVAIL_FIELD and PCENT_FIELD/IPCENT_FIELD to use the field values
where 'v' is pointing to, i.e., either the block_values or the
inode_values.
* src/df.c (main): Remove setting of grand_fsu.fsu_blocks in the
inode_format case as this is no longer needed and would lead to
wrong results once when mixed block/inode fields will be used.
* src/df.c (main): Cleanup the code at the end regarding
file_systems_processed to make the code clearer.
* src/df.c (inode_format): Remove variable.
(main): Remove initialization of the above variable.
In getopts loop, directly set the header_mode to INODES_MODE
instead of using the above variable. Afterwards, remove the
mapping to INODES_MODE as it is already set.
* src/df.c (posix_format): Move variable ...
(main): ... to here.
* src/df.c (print_table): Enhance the comment about 2-line format
in cases where the SOURCE_FIELD exceeds 20 chars, as such
behavior has been removed long ago by commit v8.10-40-g99679ff.
* src/df.c (Display modes): Add OUTPUT_MODE, remove unused NMODES.
(display_field_t): Remove unnecessary NFIELDS.
(field_data_t): Add member 'arg' for the field name in the --output
argument. Add member 'used' to remember if a field is already used
in the columns array.
(field_data): Add values for the above new members arg and used.
(all_args_string): Add variable which represents the argument for
the --output option which includes all fields.
(OUTPUT_OPTION): Add enum to identify the long --output option.
(long_options): Add optional-argument --output option.
(alloc_field): Assert that the field is not already used.
Mark the field as used.
(decode_output_arg): Add function to parse the comma-separated
field list passed to the --output option in order to add the
appropriate fields to the columns array.
(get_field_list): Add case for the new OUTPUT_MODE to add all
available fields to columns in the case the --output option
has been passed without any values. Use the comma-separated
field list form to pass to decode_output_arg to keep the field
header mapping for the OUTPUT_MODE only on one place.
(main): Define format string msg_mut_excl to be used in the
following checks whether the use of --output and the other
option is mutually exclusive.
In the getopt_long loop, add a check to the case for the -i option
to issue an error message when it is used together with --output;
Likewise for -T and -P.
Add a new case for OUTPUT_OPTION, together with similar checks as
above and eventually passing the optarg to decode_output_arg.
After the getopt_long loop, consider the OUTPUT_MODE case in order
not to run into -h or -P mode.
* src/df.c (get_dev): Also xstrdup the dev_name, and free it
afterwards to silence a valgrind warning about definitely lost
memory.
(main): Free the columns store to silence valgrind, guarded by
the IF_LINT macro.
* src/df.c (main): Pass "total" as the mount point to get_dev if
the SOURCE_FIELD is not among the columns to output.
* tests/df/df-output.sh: Change the test to ensure the content of
the target field of the grand total line: if the source field is
present, then the target should be "-", else the target field should
be "target".
* NEWS (Changes in behavior): Enhance the exiting NEWS entry.
* doc/coreutils.texi (df invocation): Document the content of the
source and target field in the grand total line.
* src/df.c (main): Add another condition to the need_fs_type
parameter of read_file_system_list whether the FSTYPE_FIELD is
used or not.
* src/df.c (get_header): Indicate the block size used,
in the "size" header, when using --output without -h.
* tests/df/df-output.sh: Adjust for, and add an extra test for,
the new behavior.
|
|
* src/df.c (get_header): Mark two "%s-%s" strings for translation
and give translators a hint what each is for.
|
|
* src/df.c (main): Add conditions to fail when the mount list cannot
be read: this includes the cases when a file name argument is given
and any of -a, -l, -t or -x is used.
* doc/coreutils.texi: Document the additional error conditions.
* tests/df/no-mtab-status: Add a new test.
* tests/Makefile.am: Reference the new test.
* NEWS: Mention the fix.

When the combination of the file system options with given files or
devices does not lead to output, "df --total" would exit successfully
although it should not.
Examples:
$ df --total --type=xfs / # when / is not an XFS file system
$ df --total --local -t nfs DIR # nfs is remote per se ...
$ df --total -t qwerty /dev/sdb5 # typo in file system type
Furthermore, "df --total" would not print the error message "no file
systems processed" when the file argument does not exist or is otherwise
not accessible.
Example:
$ df --total __not_exist__
These 2 bugs are present since --total was added by commit
v6.12-166-gea2887b.
* src/df.c (get_dev): Do not set file_systems_processed to true when
force_fsu is true, i.e. when the row for the "total" line is processed.
(main): Don't print totals unless we've processed a file system.
Also only print the "no FS processed" message if there was no
preceding diagnostic.
* tests/df/total-unprocessed: Add a new test.
* tests/Makefile.am: Reference the new test.
* NEWS: Mention the fix.

It's awkward to read and problematic for scripts when
control characters like '\n' are output.
Note other fields are already handled with mbsalign,
which converts non printable chars to the replacement char.
A caveat to note with that, is the replacement char takes
a place in the field and so possibly truncates the field
if it was the widest field in the records.
Note a more general replacement function, that
handles all printable, or non white space characters,
would require more sophisticated support for various
encodings, and the complexity vs benefit was not
deemed beneficial enough at present.
Perhaps in future a more general replacement function
could be shared between the various utilities.
Note <space> is unaffected in any field,
which could impact scripts processing the output.
However any of the number fields at least could have
spaces considering `LANG=fr_FR df -B\'1`, so it's
probably best to leave spaces, which also allows
scripts to handle mount points with spaces without change.
* src/df.c (hide_problematic_chars): Replace control chars with '?'.
* tests/df/problematic-chars: Add a new root only test.
* tests/Makefile.am: Reference the new test.

* src/df.c (MEGABYTES_OPTION): Add enum and mark it for removal

the long form is used. Document the short -m option to
exist only for BSD compatibility.

On systems with recent kernel/tools, a symlink from /etc/mtab to
/proc/mounts, and a by-UUID mount (i.e., soon, nearly everyone),
you will see something like the following when running "df -hT":
(this has been truncated to fit in a width-limited ChangeLog file)
Filesystem Type Siz...
rootfs rootfs 11G
udev devtmpfs 3.8G
tmpfs tmpfs 774M
/dev/disk/by-uuid/828fc648-9f30-43d8-a0b1-f7096a2edb66 ext4 11G
tmpfs tmpfs 1.6G
/dev/sda2 ext3 494M
/dev/sda5 ext4 12G
/dev/sda6 ext4 9.9G
Contrast that with what we're used to seeing (modulo the
two entries mounted on "/", which is a separate problem):
Filesystem Type Size Used Avail Use% Mounted on
rootfs rootfs 11G 1.9G 8.0G 19% /
udev devtmpfs 3.8G 0 3.8G 0% /dev
tmpfs tmpfs 774M 376K 774M 1% /run
/dev/sda3 ext4 11G 1.9G 8.0G 19% /
tmpfs tmpfs 1.6G 8.0K 1.6G 1% /run/shm
/dev/sda2 ext3 494M 78M 392M 17% /boot
/dev/sda5 ext4 12G 7.6G 3.7G 68% /usr
/dev/sda6 ext4 9.9G 6.6G 2.8G 71% /var
When that long /dev/disk/by-uuid/... name is merely a symlink
to a much shorter (and often more useful) device name like
"/dev/sda3", and when it's part of a listing of all file systems,
I would much prefer to see only the latter. Similarly, when using
an encrypted root file system, you would see a name like
/dev/mapper/luks-828fc648-9f30-43d8-a0b1-f7196a2edb66 pointing
to say, /dev/dm-0, I prefer the shorter name.
I.e., if I explicitly run
"df -hT /dev/disk/by-uuid/828fc648-9f30-43d8-a0b1-f7096a2edb66",
then, it's fine -- and expected -- to print to the long name.
It was explicitly given. However, with no non-option argument,
df should print the shorter name. Note that performing this
translation at a lower level (via a change to gnulib's mountlist.c)
would make it impossible to distinguish those two cases.
* src/df.c: Include "canonicalize.h".
(get_dev): Add a parameter, telling when we're in process-all-
mount-points mode; update all callers. When true, resolve
UUID-suffixed symlinks.
* NEWS (Changes in behavior): Mention it.

* src/df.c (alloc_table_row): A new function to allocate storage
for a row of strings.
(print_table): A new function to interate over all stored strings in
the table, and apply alignment honoring the max width of each column.
(get_header): Renamed from print_header, and adjusted accordingly.
(get_dev): Renamed from show_dev. Also we no longer wrap longer
device names over two lines, which can be an unexpected issue for
scripts parsing the output from df.
(get_disk): s/show_/get_/
(get_point): Likewise.
(get_entry): Likewise.
(get_all_entries): Likewise.
* NEWS: Mention the change.

(sc_long_lines): New rule.
* HACKING: Use shorter URLs to the same material.

Reformat to fit within 80 columns.
* doc/Makefile.am (BAD_POSIX_PERL): New macro.
* doc/coreutils.texi: Reword slightly, to make menus and
index lines shorter.
* src/md5sum.c: Redo --help output so that it fits within 79
columns, since that's a bit more portable and all the other --help
strings fit in 79 columns.

* src/find-mount-point.c: A new file refactoring
find_mount_point() out from df.c
* src/find-mount-point.h: Likewise.
* src/df.c: Use the new find-mount-point module.
* src/stat.c (print_stat): Handle the new %m format.
(find_bind_mount): A new function to
return the bind mount for a file if any.
(out_mount_mount): Print the bind mount for a file, or else
the standard mount point given by the find-mount-point module.
(usage): Document the %m format directive.
* src/Makefile.am: Reference the refactored find-mount-point.c
* po/POTFILES.in: Add find_mount_point.c to the translation list
* doc/coreutils.texi (stat invocation): Document %m,
and how it may differ from the mount point that df outputs.
* test/misc/stat-mount: A new test to correlate mount points
output from df and stat.
* tests/Makefile.am: Reference the new test.
* NEWS: Mention the new feature
* THANKS: Add the author

* src/df (show_point): Remove the optimization for comparing
the specified path with the device name, as this produces
inconsistent results in the presence of bind mounts. For bind
mounts, the device name is populated with the bind mount target.
* NEWS: Mention the change in behavior.
|
|
* src/du.c (usage): Print better --blocksize description.
Prompted by Samuel Thibault in <http://bugs.debian.org/353100>.
* src/df.c (usage): Likewise.
* src/ls.c (usage): Likewise.

E.g.,
- size_t desired_width IF_LINT (= 0);
+ size_t desired_width IF_LINT ( = 0);
Use this command:
g grep -l IF_LINT | grep '\.[ch]$' \
| xargs perl -pi -e 's/(IF_LINT \()= /$1 = /'
|
|
Run this command:
git ls-files | grep '\.[ch]$' \
| xargs perl -pi -e 's/for \(;;\)/while (true)/g'
...except for randint.c, which does not include stdbool.h.
In that case, use "while (1)".
* gl/lib/randint.c (randint_genmax): Use "while (1)" for infloops.
* src/cat.c (simple_cat, cat): Use "while (true)" for infloops.
* gl/lib/randread.c (readsource, readisaac): Likewise.
* src/copy.c (copy_reg): Likewise.
* src/csplit.c (record_line_starts, process_regexp): Likewise.
* src/cut.c (set_fields): Likewise.
* src/dd.c (iread, parse_symbols): Likewise.
* src/df.c (find_mount_point, main): Likewise.
* src/du.c (main): Likewise.
* src/expand.c (expand): Likewise.
* src/factor.c (factor_using_division, do_stdin): Likewise.
* src/fmt.c (get_space): Likewise.
* src/ls.c (decode_switches): Likewise.
* src/od.c (main): Likewise.
* src/pr.c (main, read_line): Likewise.
* src/shred.c (dopass, genpattern): Likewise.
* src/sort.c (initbuf, fillbuf, getmonth, keycompare): Likewise.
* src/split.c (bytes_split, lines_split): Likewise.
* src/tac.c (tac_seekable): Likewise.
* src/test.c (and, or): Likewise.
* src/tr.c (squeeze_filter, main): Likewise.
* src/tsort.c (search_item): Likewise.
* src/unexpand.c (unexpand): Likewise.
* src/uniq.c (main): Likewise.
* src/yes.c (main): Likewise.

* src/df.c (print_header): Use fputs rather than printf in more places.
Suggested by Eric Blake.
|
|
Use this command:
git ls-files | grep -v COPYING \
| xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \
build-aux/update-copyright
|
|
* src/df.c (print_header): Add a comment telling translators to
retain the message length, and another to align header translations.
|
|
This is because bitwise operators are:
- confusing and inconsistent in a boolean context
- non short circuiting
- brittle in C89 where bool can be an int (so > 1)
|
|
* src/df.c: Don't include "canonicalize.h". No longer needed,
since canonicalize_file_name is now guaranteed to be declared
in <stdlib.h>, thanks to gnulib.
