This way we can check whether the repo has an appropriate ratio of packed to loose objects to help determine whether it's behaving correctly. Add a utility to easily traverse all packfiles in a given repository. Use it in packfile.c and remove a redundant call to prepare_packed_git(), which is already called in get_all_packs(). Signed-off-by: Emily Shaffer --- Perhaps the macro should be in another patch? I didn't spend a lot of time looking for anybody who could conceivably be iterating packs; if I were to do so, I'd break this change out separately. I considered following the pattern in the rest of the file, where the foreach takes a callback and data pointer, but found it would be cumbersome to use with for_each_packed_object() - I'd have to add a new callback just to handle the pack, and bundle that function's callback data along with the callback pointer. It seemed like overkill. - Emily Documentation/git-bugreport.txt | 1 + bugreport.c | 30 ++++++++++++++++++++++++++++++ object-store.h | 6 ++++++ packfile.c | 3 +-- 4 files changed, 38 insertions(+), 2 deletions(-) diff --git a/Documentation/git-bugreport.txt b/Documentation/git-bugreport.txt index 7e1ed44cb4..309b34fc42 100644 --- a/Documentation/git-bugreport.txt +++ b/Documentation/git-bugreport.txt @@ -33,6 +33,7 @@ The following information is captured automatically: - Selected config values - A list of enabled hooks - The number of loose objects in the repository + - The number of packs and packed objects in the repository OPTIONS ------- diff --git a/bugreport.c b/bugreport.c index 9552e2922e..d554488f3e 100644 --- a/bugreport.c +++ b/bugreport.c @@ -177,6 +177,33 @@ static void get_loose_object_summary(struct strbuf *obj_info, int nongit) { total_count_questionable ?
