CHANGES for 0.68

fgetc() returns int, not char; fixes -Werror build on armv7

sync dist file list

fix free() on uninitialized variable upon error in gw_output_file_blame() ok op@

tweak wording to make it clearer where the mentioned -u option applies

got patch: handle "\ No newline at end of file"

reuse apply_hunk in patch_file when creating a file

mention that 'got patch' is compatible with 'cvs diff -u' output

mention that 'got patch' can read diffs produced by Git, to avoid any doubt

fix pack progress object counter for loose objects Move pack progres object accounting to a single place. This makes it easier to account for the case were only loose objects are packed. A wrong amount of objects was reported before when packing loose ones.

in pack progress output, remove excluded objects from 'found' objects counter

fix a bug where 'gotadmin pack' packed too many objects unless -a was used

subordinate clauses preceding the main clause are offset by a comma

fix potential NULL deref in error path of got_object_idset_remove()

got patch: prefer new name if not /dev/null and not a git-style diff This fixes a common issue when for e.g. generating patches with $ diff -u foo.orig foo where 'got patch' failed because 'foo.orig' has an 'unexpected status'. prodded by naddy, ok stsp

const-ify string table

move got_patch file status checking in worktree.c check_file_status used got_worktree_status to check if the file was in an allowed state, but it's wrong since the callback is not invoked on unchanged files. While here also fix a relate bug: unlink(newpath) is in the wrong spot and ends up removing files even when it shouldn't, so move it early in the got_worktree_schedule_* error handling. Finally, update the appropriate test case. It was passing before because got_worktree_schedule_add returned GOT_ERR_FILE_STATUS, not because check_file_status failed. ok stsp@

explicitly include <unistd.h> for close(2)

move got_errors[] table into a single compilation unit (error.c) ok stsp

rm unused vars

const-ify tables ok thomas_adam millert
