all: use die() rather than error(EXIT_FAILURE)2016-10-16T11:23:55ZPádraig BradyP@draigBrady.com2016-10-15T22:10:35Zurn:sha1:492dcb2eb191b844a2fd5e51db3eed85289bea1f
die() has the advantage of being apparent to the compiler
that it doesn't return, which will avoid warnings in some cases,
and possibly generate better code.
* cfg.mk (sc_die_EXIT_FAILURE): A new syntax check rule to
catch any new uses of error (CONSTANT, ...);
df: improve performance with many mount points2016-08-03T11:35:47ZPhilipp Thomaspth@suse.de2016-07-31T19:24:18Zurn:sha1:1c17f61ef993a5ee5fb0d3bc47b7b25782ae386c
Use hash table for seaching in filter_mount_list() and get_dev()
This improves performance for 20K mount entries from:
real 0m1.731s
user 0m0.532s
sys 0m1.188s
to:
real 0m1.066s
user 0m0.028s
sys 0m1.032s
* src/df.c (devlist_table): Define hash table.
(devlist_hash): Add hash function.
(devlist_compare): Add hash comparison function.
(devlist_for_dev): Add lookup function.
(devlist_free): Add cleanup function.
(filter_mount_list): Use the above hash table.
While at it, rename the variable 'devlist' to 'seen_dev' for
better readability.
(me_for_dev): Use the above lookup function.
NEWS: Mention the improvement.
THANKS.in: Remove the committer; add original submitter Josef Cejka.
maint: update all copyright year number ranges2016-01-01T14:10:41ZPádraig BradyP@draigBrady.com2016-01-01T14:10:41Zurn:sha1:b16e999f553b682e74e0a56750f649da05130c4f
Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.

all: avoid quoting file names when possible2015-11-04T23:30:14ZPádraig BradyP@draigBrady.com2015-11-01T18:53:26Zurn:sha1:08e8fd7e38f2dae7c69c54eb22d508b6517e66e5
Quote file names using the "shell-escape" or "shell-escape-always"
methods, which quote as appropriate for most shells,
and better support copy and paste of presented names.
The "always" variant is used when the file name is
embedded in an error message with surrounding spaces.
* cfg.mk (sc_error_shell_quotes): A new syntax check rule
to suggest quotef() where appropriate.
(sc_error_shell_always_quotes): Likewise for quoteaf().
* src/system.h (quotef): A new define to apply shell quoting
when needed. I.E. when shell character or ':' is present.
(quoteaf): Likewise, but always quote.
* src/*.c: Use quotef() and quoteaf() rather than quote()
where appropriate.
* tests/: Adjust accordingly.
build: Pacify GCC 5 on 32-bit hosts2015-10-03T07:32:34ZPaul Eggerteggert@cs.ucla.edu2015-10-03T07:24:43Zurn:sha1:f689642bac132e189d0c0960c171ae9043a37298
This pacifies GCC 5 in a better way, without disabling diagnostics.
* src/df.c (main): Tell compiler that optind is positive.
* src/shred.c (known): New function.
(dopass): Go back to off_t for file sizes.
Avoid integer overflow if we run off the end of the file.
Tell compiler that a write cannot write more bytes than requested.
df: prioritize mounts nearer the device root2015-09-23T00:02:44ZDave Chilukchiluk@canonical.com2015-09-21T20:04:11Zurn:sha1:3babaf83875ceac896c8dd3a64248e955dfecef9
In the presence of bind mounts of a device, the 4th "mount root" field
from /proc/self/mountinfo is now considered, so as to prefer mount
points closer to the root of the device. Note on older systems with
an /etc/mtab file, the source device was listed as the originating
directory, and so this was not an issue.
Details at http://pad.lv/1432871
* src/df.c (filter_mount_list): When deduplicating mount entries,
only prefer sources nearer or at the root of the device, when the
target is nearer the root of the device.
* NEWS: Mention the change in behavior.
maint: clarify df's use of device IDs from /proc/self/mountinfo2015-06-28T02:56:41ZPádraig BradyP@draigBrady.com2015-06-28T02:53:51Zurn:sha1:eff511bd3cecaab30df75a854f01566ce45c5876
* src/df.c (filter_mount_list): Clarify why we still stat even
though devices IDs may already be available. Note using
/proc/self/mountinfo is still an advantage to get filtered items
with accurate device patchs in chroots and with bind mounts.
I.E. on older setups with static /etc/mtab, df will now
bypass that to get the more accuracte and dynamic info.
df: fix --local hanging with inaccessible remote mounts2015-04-13T08:20:55ZPádraig BradyP@draigBrady.com2015-04-05T17:21:38Zurn:sha1:1b1c40e1d6f8cf30b6c7c9d31bbddbc3d5cc72e6
* src/df.c (filter_mount_list): With -l, avoid stating remote mounts.
* init.cfg: Avoid test hangs with inaccessible remote mounts.
* tests/df/no-mtab-status.sh: Skip with inaccessible remote mounts.
* tests/df/skip-rootfs.sh: Likewise.
* tests/df/total-verify.sh: Likewise.
* NEWS: Mention the bug fix.
