pack-objects: remove unnecessary NULL check

2017-07-20T21:50:20Z

If done_pbase_paths is NULL then done_pbase_paths_num must be zero and done_pbase_path_pos() returns -1 without accessing the array, so the check is not necessary. If the invariant was violated then the check would make sure we keep on going and allocate the necessary amount of memory in the next ALLOC_GROW call. That sounds nice, but all array entries except for one would contain garbage data. If the invariant was violated without the check we'd get a segfault in done_pbase_path_pos(), i.e. an observable crash, alerting us of the presence of a bug. Currently there is no such bug: Only the functions check_pbase_path() and cleanup_preferred_base() change pointer and counter, and both make sure to keep them in sync. Get rid of the check anyway to allow us to see if later changes introduce such a defect, and to simplify the code. Detected by Coverity Scan.

use MOVE_ARRAY

2017-07-17T21:54:56Z

Simplify the code for moving members inside of an array and make it more robust by using the helper macro MOVE_ARRAY. It calculates the size based on the specified number of elements for us and supports NULL pointers when that number is zero. Raw memmove(3) calls with NULL can cause the compiler to (over-eagerly) optimize out later NULL checks. This patch was generated with contrib/coccinelle/array.cocci and spatch (Coccinelle).

Merge branch 'ab/free-and-null'

A common pattern to free a piece of memory and assign NULL to the pointer that used to point at it has been replaced with a new FREE_AND_NULL() macro. * ab/free-and-null: *.[ch] refactoring: make use of the FREE_AND_NULL() macro coccinelle: make use of the "expression" FREE_AND_NULL() rule coccinelle: add a rule to make "expression" code use FREE_AND_NULL() coccinelle: make use of the "type" FREE_AND_NULL() rule coccinelle: add a rule to make "type" code use FREE_AND_NULL() git-compat-util: add a FREE_AND_NULL() wrapper around free(ptr); ptr = NULL

Merge branch 'bw/config-h'

2017-06-24T21:28:41Z

Fix configuration codepath to pay proper attention to commondir that is used in multi-worktree situation, and isolate config API into its own header file. * bw/config-h: config: don't implicitly use gitdir or commondir config: respect commondir setup: teach discover_git_directory to respect the commondir config: don't include config.h by default config: remove git_config_iter config: create config.h

coccinelle: make use of the "type" FREE_AND_NULL() rule

2017-06-16T19:44:03Z

Apply the result of the just-added coccinelle rule. This manually excludes a few occurrences, mostly things that resulted in many FREE_AND_NULL() on one line, that'll be manually fixed in a subsequent change. Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

config: don't include config.h by default

2017-06-15T19:56:22Z

Stop including config.h by default in cache.h. Instead only include config.h in those files which require use of the config system. Signed-off-by: Brandon Williams Signed-off-by: Junio C Hamano

"pack-objects" can stream a slice of an existing packfile out when the pack bitmap can tell that the reachable objects are all needed in the output, without inspecting individual objects. This strategy however would not work well when "--local" and other options are in use, and need to be disabled. * jk/disable-pack-reuse-when-broken: t5310: fix "; do" style pack-objects: disable pack reuse for object-selection options
