2016-01-01maint: update all copyright year number rangesPádraig Brady
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.
2015-01-01maint: update all copyright year number rangesPádraig Brady
Run "make update-copyright" and then... * tests/sample-test: Adjust to use the single most recent year. * tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message, so that year is updated automatically in future.
2014-08-22maint: avoid int64_t and similar types unless they're neededPaul Eggert
C11 doesn't require them, even POSIX doesn't strictly require the 64-bit versions, and it makes the code a bit clearer if they're used only when needed. * src/copy.c (write_zeros, extent_copy): * src/extent-scan.h (struct extent_info.ext_length): Use off_t, not uint64_t, for a value derived from a file offset. * src/extent-scan.h (struct extent_info.ext_flags) Prefer plain unsigned int to uint32_t where either will do. (struct extent_scan.ei_count): Use size_t, not uint32_t, for a value bounded by SIZE_MAX. * src/factor.c (MAGIC64, MAGIC63, MAGIC65): Remove unnecessary casts to uint64_t.
2014-01-02maint: update all copyright year number rangesBernhard Voelker
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.

Run "make update-copyright".
2011-04-06copy: handle mergeable extents across fiemap scansPádraig Brady
* extent-scan.h (extent_scan_free): Init the pointer to NULL, and reset the count to 0, so that we can realloc the buffer. * src/extent-scan.c (extent_scan_init): Likewise. (extent_scan_read): Loop over multiple fiemap scans, so we handle mergeable extents that span across fiemap scan boundaries. Once we have enough unique extents, return so as to minimize memory use.
2011-03-31copy: with fiemap copy, only sync when neededPádraig Brady
* src/extent-scan.h (struct extent_scan): Add the fm_flags member to pass to the fiemap scan. * src/extent-scan.c (extent_need_sync): A new function used to detect Linux kernels before 2.6.38. (extent_scan_init): Add FIEMAP_FLAG_SYNC when needed. * tests/cp/sparse-fiemap: Adjust comment. * NEWS: Mention the change in behavior. Indirectly suggested by Mike Frysinger
2011-01-31maint: update copyright year lists in new filesJim Meyering
* src/extent-scan.h: Update copyright year list. * src/extent-scan.c: Likewise. * tests/cp/sparse-fiemap: Likewise.
2011-01-30extent-scan: adjust naming and formattingJim Meyering
* src/extent-scan.h [struct extent_scan]: Rename member: s/hit_last_extent/hit_final_extent/. "final" is clearer, since "last" can be interpreted as "preceding". Rename extent-scan functions to start with extent_scan_. * src/Makefile.am (copy_sources): Also distribute extent-scan.h. * src/extent-scan.c: Don't include error.h or quote.h. Neither is used. * src/copy.c: shorten a comment to fit in 80 columns * src/extent-scan.c, src/extent-scan.h: Correct formatting.
2011-01-30fiemap copy: add extent-scan.[ch], avoid a double-free and reorganizejeff.liu
Changes: ======== 1. fix write_zeros() per Jim's comments. 2. remove char const *fname from struct extent_scan. 3. change the signature of open_extent_scan() from "void open_extent_scan(struct extent_scan **scan)" to "void open_extent_scan(struct extent_scan *scan)" to avoid having to malloc the extent_scan variable; instead save it on the stack. 4. move close_extent_scan() from a function defined in extent-scan.c to extent-scan.h as a macro definition, but it does nothing for now, since initial extent scan defined at stack. 5. add a macro "free_extents_info()" defined at extent-scan.h to release the memory allocated to extent info which should be called combine with get_extents_info(), it just one line, so IMHO, define it as macro should be ok. * src/extent-scan.c: New file; functions to read "extents". * src/extent-scan.h: Header file of extent-scan.c. * src/Makefile.am: Reference it and link it to copy_source. * src/copy.c: Use the new functions and avoid double-free.
