* btrfs-progs: cleanup option index argument from getopt_longDavid Sterba2015-04-08
| | | | | | | We're not using it anywhere. The best practice is to add enums with values > 255 for the long options, option index counting is error prone. Signed-off-by: David Sterba <dsterba@suse.cz>
* btrfs-progs: autoconf: use standard PACKAGE_* macrosKarel Zak2015-01-28
| | | | | | | | | | | | | - use standard PACKAGE_{NAME,VERSION,STRING,URL,...} autoconf macros rather than homemade BTRFS_BUILD_VERSION - don't #include version.h, now the file is necessary for library API only Note that "btrfs version" returns "btrfs-progs <version>" instead of the original confusing "btrfs <version>".

* btrfs-progs: drop feature defines from C files, in favour of CFLAGS definesDimitri John Ledkov2015-01-27
| | | | | | | | | | | | | | | | | | | | | | glibc 2.10+ (5+ years old) enables all the desired features: _XOPEN_SOURCE 700, __XOPEN2K8, POSIX_C_SOURCE, DEFAULT_SOURCE; with a single _GNU_SOURCE define in the makefile alone. For portability to other libc implementations (e.g. dietlibc) _XOPEN_SOURCE=700 is also defined. This also resolves Debian bug report filed by Michael Tautschnig - "Inconsistent use of _XOPEN_SOURCE results in conflicting declarations". Whilst I was not able to reproduce the results, the reported fact is that _XOPEN_SOURCE set to 500 in one set of files (e.g. cmds-filesystem.c) generates/defines different struct stat from other files (cmds-replace.c). This patch thus cleans up all feature defines, and sets them at a consistent level.

* btrfs-progs: Fix wrong return value when executing 'fi show' on umounted device.Qu Wenruo2015-01-14
| | | | | | | | | | | | | | | | When executing 'btrfs fi show' on unmounted device, even no problem happens, the return value is still 1 not 0. The problem lies in search_umounted_fs_uuids(), where when it finds the given uuid, it should return 1, but later uuid copy overwrites the return value, causing it always return 0 under that case. Fix it by pass found as pointer, and return value only indicates whether anything wrong happens, whether found or not is stored in the new parameter.

* btrfs-progs: Fix btrfs fi show by uuid and labelJustin Maggard2014-12-29
| | | | | | | | | | | | | | | | Commit 8be2fff (btrfs-progs: apply realpath for btrfs fi show when mount point is given) changed the behavior of btrfs fi show to return an error if the call to realpath() failed. This broke the ability to specify a filesystem by uuid or label. So let's not consider a failed call to realpath() as an error. If the user really specified a bad device, just return nothing like we did before.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | btrfs_scan_lblikd() is called by most the device related command functions. And btrfs_scan_lblkid() is most expensive function and it becomes more expensive as number of devices in the system increase. Further some threads call this function more than once for absolutely no extra benefit and the real waste of resources. Below list of threads and number of times btrfs_scan_lblkid() is called in that thread. btrfs-find-root 1 btrfs rescue super-recover 2 btrfs-debug-tree 1 btrfs-image -r 2 btrfs check 2 btrfs restore 2 calc-size NC btrfs-corrupt-block NC btrfs-image NC btrfs-map-logical 1 btrfs-select-super NC btrfstune 2 btrfs-zero-log NC tester NC quick-test.c NC btrfs-convert 0 mkfs #number of devices to be mkfs btrfs label set unmounted 2 btrfs get label unmounted 2 This patch will: move out calling register_one_device with in btrfs_scan_lblkid() and so function setting the BTRFS_UPDATE_KERNEL to yes will call btrfs_register_all_devices() separately. introduce a global variable scan_done, which is set when scan is done succssfully per thread. So that following calls to this function will just return success. Further if any function needs to force scan after scan_done is set, then it can be done when there is such a requirement, but as of now there isn't any such requirement.
