== Summary ==
This series continues to focus on splitting declarations from cache.h to
separate headers, and also cleans up some other small header issues. By
patch 17, cache.h is gone.
== Changes ==
Since v2 (thanks to Jonathan Tan for feedback and suggestions!)
* Wording fixes & improvements suggested by Jonathan
* Pulled another line from the oidhash() patch (27) into the khash patch
(25) to make it easier to review
* Split the old patch 26 into two. Somehow my object-ll and hash-ll changes
got smashed into the same patch (before v1), and I didn't notice until
after v2 was sent out. Split them out two separate patches to make them
easier to review.
Since v1 (thanks to Calvin, Glen, Junio, and Peff for feedback and
suggestions!)
* Split the first patch into two, correct the explanation around existing
bug, and tweak how global is removed
* New patch 24 to rename ll-merge.[ch] to merge-ll.[ch]
* Patch 25 split out of the old patch 23 to document the khash.h change in
isolation
== Reviewer Focus (see also "Overview" section, below) ==
While the series may look long and big, it's really mostly just (a) moving
lots of code (so --color-moved is handy), and (b) adding (or removing)
includes repeatedly throughout the code. These are just more of the same
kinds of changes from the previous series.
However, there are a few exceptions that do not fit in these two categories,
which should be reviewed more closely:
* Patches 1-3 & 6
* Patch 17, the Documentation and Makefile changes
* Patch 24 & 27
Patches 11 & 28 might also merit a little closer review.
== Maintainer notes from v1 ==
(1) This series is built on top of a merge of en/header-split-cache-h-part-2
into master, (2) This series has no conflicts with next, but has three
simple & small conflicts with seen:
* a textual conflict with tl/notes-separator (affecting builtin/notes.c; to
address, nuke the conflict region and add an include of alloc.h after
builtin.h)
* a textual & semantic conflict with cw/strbuf-cleanup (affecting strbuf.c;
to address, delete the conflict region and also delete the include of
repository.h)
* a semantic conflict with rn/sparse-diff-index (affecting
builtin/diff-index.c; to address, add an include of sparse-index.h).
== Impact; interesting stats ==
By way of impact, I created a small script which before this series reports:
Total include depth of .c files: 18340
Total include depth of .h files: 1385
After this series, I see:
Total include depth of .c files: 16155
Total include depth of .h files: 1206
The script computes the number of files transitively included by each file
(not perfect, e.g. only does textual search so if the include if ifdef'd,
it'll be counted anyway), and then sums the results. I think these numbers
represent one rough measure of overall complexity humans face in
understanding files in our project, and/or that compilers take to operate.
(For reference, the total include depths for v2.40.0 were 23114 and 2981;
we've come a long way in improving it, most of that through nuking cache.h.)
== Overview ==
An overview:
* Patches 1-7: move shared code between various builtin/*.c files into
alternate shared homes (setup.c, read-cache.c).
* Patches 8-17: continue splitting declarations from cache.h into
alternative headers associated with the actual implementation of those
functions.
* Patches 18-23: remove some unnecessary includes in other header files
* Patch 24: rename ll-merge for consistency, and to get a better name
* Patches 25-28: do some header shuffling with hashmap/khash/hash, and
fsmonitor to reduce include depths
I would have just lumped patches 1-7 in with 8-17, but patches 1-3, & 6 did
some preliminary changes to allow the code movement.
== Acknowledgements ==
And thanks once again to Dscho for gitgitgadget. Getting multiple platform
testing + all the special tests (sparse, cocci, hdr-check, etc.) really
helps clean out all the issues that would otherwise hit a series like this.

Author: Elijah Newren <newren@xxxxxxxxx>
## Commit message ##
- hash-ll, hashmap: move oidhash() to hash-ll
+ object-store-ll.h: split this header out of object-store.h
- oidhash() was used by both hashmap and khash, which makes sense.
- However, the location of this function in hashmap.[ch] meant that
- khash.h had to depend upon hashmap.h, making people unfamiliar with
- khash think that it was built upon hashmap. (Or at least, I personally
- was confused for a while about this in the past.)
+ The vast majority of files including object-store.h did not need dir.h
+ nor khash.h. Split the header into two files, and let most just depend
+ upon object-store-ll.h, while letting the two callers that need it
+ depend on the full object-store.h.
- Move this function to hash-ll, so that khash.h can stop depending upon
- hashmap.h.
+ After this patch:
+ $ git grep -h include..object-store | sort | uniq -c
+ 2 #include "object-store.h"
+ 129 #include "object-store-ll.h"
- This has another benefit as well: it allows us to remove hashmap.h's
- dependency on hash-ll.h. While some callers of hashmap.h were making
- use of oidhash, most were not, so this change provides another way to
- reduce the number of includes.
-
- Diff best viewed with `--color-moved`. Note that there's a small but
- important change to khash.h in this patch as well to allow this move,
- which is easy to overlook.
+ Diff best viewed with `--color-moved`.
