This patch series puts some mundane groundwork for experimentation with a new
hashing algorithm in git-hash-object.
Some time has passed since my last patches, and I see, that work on new
hashing algorithm progressed nicely since then:
* brian m. carlson implemented vtable for hash algorithm selection and pushed
the repository format front - thanks to him it's now quite easy to
experimentally replace hashing functions and, e.g. do some performance testing.
* _a lot of people_ contributed to the transition plan, and now it's available
in text format in Documentation dir - Thank you all! It's much more readable
this way.
Patch 1 is not directly related to object_id conversions but helped with
debugging t5540, which kept failing on master for me (spoiler: it was Fedora
fault). It helps with debugging of failing git-push over HTTP in case of
internal server error, so I think it might be worthwhile.
Patch 2 is a small adjustment to .clang-format, which prevents unnecessary
line breaks after function return type.
Patch 6 is a tiny fix in oidclr function.
All other patches are progressive conversions to struct object_id with some
formatting fixes sprinkled in. These should be somewhat uncontroversial, I hope.

When git push fails due to server-side WebDAV error, it's not easy to
point to the main culprit. Additional information about exact cURL
error and HTTP server response is helpful for debugging purpose.
New error log helped me pinpoint failing test t5540-http-push-webdav
to a missing Apache dependency in Fedora 27:

The penalty of 5 makes clang-format very eager to put even short type
declarations (e.g. "extern int") into a separate line, even when
breaking parameters list is sufficient.

Convert the declaration of struct sha1_stat. Adjust all usages of this
struct and replace hash{clr,cmp,cpy} with oid{clr,cmp,cpy} wherever
possible.
Remove macro EMPTY_BLOB_SHA1_BIN, as it's no longer used.

As long as GIT_SHA1_RAWSZ is equal to GIT_MAX_RAWSZ there's no problem,
but when new hashing algorithm will be in place this memset will clear
only 20-byte prefix of hash buffer.
Alternatively, hashclr implementation could be adjusted, but this
function is almost removed from codebase already. Separate
implementation of oidclr prevents potential buffer overrun in case
someone incorrectly used hashclr on object_id in future.

Convert the definition and declaration of write_notes_tree to
struct object_id and adjust usage of this function.
Additionally, improve style of small part of this function, as old
formatting made it hard to understand at glance what this part of
code is doing.

Convert the definition and declaration of write_sha1_file to
struct object_id and adjust usage of this function.
This commit also converts static function write_sha1_file_prepare, as it
is closely related.
Replace sha1_to_hex, hashcpy and hashclr with their oid equivalents
wherever possible.

This patch seems reasonable to me - it is a little strange that,
currently, an error message is printed upon an XML error and upon
failure of start_active_slot(), but not when the slot cannot be run.
This patch fills the gap.

I'm not very familiar with clang-format, so no comment from me here.

Ah, good catch. I would write the memset line as
"memset(oid, 0, sizeof(*oid))", but the existing one is fine too.

I've looked at those and they appear to be obviously correct.

It looks like the indentation has changed here. Was that intentional?

I have no strong opinions about these two patches, but didn't see
anything that looked problematic. Better debugging is always nice.
> Patch 6 is a tiny fix in oidclr function.
I think this is a good direction to go in.
> All other patches are progressive conversions to struct object_id with some
> formatting fixes sprinkled in. These should be somewhat uncontroversial, I hope.
Overall, I like the direction this series is going.
When I've made changes to the sha1_file functions, I've traditionally
moved them away from using "sha1_file" to "object_file" to ensure that
we make it a bit more obvious that they handle object_id structs and
aren't limited to SHA-1. For consistency, it might be nice to make that
change.
Other than that and the question I had about the formatting, I think the
series looks good.

Yes. After every commit, I am running clang-format on lines, that I
touch to verify formatting and
decide if I want to include formatting fixes or not. In this case,
function parameters were
aligned using spaces only (which is arguably hard to see in the mail)
- now they are aligned to first

I will address this in V2 and add several more conversions, that
are sufficient to make git hash-object -w work with sha-256 (which I will
send as separate RFC thread).
I started converting functions needed for cat-file, but number of places,
that still needs to be touched up grew quite rapidly, so it'll take some
time :).

Compared to v1:
Following brian's suggestion I renamed following functions and struct
names to indicate, that they are no longer intended for sha1 algorithm
only:
struct sha1_stat -> struct oid_stat
pretend_sha1_file -> pretend_object_file
write_sha1_file -> write_object_file
hash_sha1_file -> hash_object_file
hash_sha1_file_literally -> hash_object_file_literally
Added two more patches converting some more functions to struct object_id
and one with pure function rename.
Patryk Obara (14):
http-push: improve error log
clang-format: adjust penalty for return type line break
sha1_file: convert pretend_sha1_file to object_id
dir: convert struct sha1_stat to use object_id
sha1_file: convert hash_sha1_file to object_id
cache: clear whole hash buffer with oidclr
match-trees: convert splice_tree to object_id
commit: convert commit_tree* to object_id
notes: convert combine_notes_* to object_id
notes: convert write_notes_tree to object_id
sha1_file: convert write_sha1_file to object_id
sha1_file: convert force_object_loose to object_id
sha1_file: convert write_loose_object to object_id
sha1_file: rename hash_sha1_file_literally

When git push fails due to server-side WebDAV error, it's not easy to
point to the main culprit. Additional information about exact cURL
error and HTTP server response is helpful for debugging purpose.
New error log helped me pinpoint failing test t5540-http-push-webdav
to a missing Apache dependency in Fedora 27:

The penalty of 5 makes clang-format very eager to put even short type
declarations (e.g. "extern int") into a separate line, even when
breaking parameters list is sufficient.

Convert the declaration and definition of pretend_sha1_file to use
struct object_id and adjust all usages of this function. Rename it to
pretend_object_file.

Convert the declaration of struct sha1_stat. Adjust all usages of this
struct and replace hash{clr,cmp,cpy} with oid{clr,cmp,cpy} wherever
possible. Rename it to struct oid_stat.
Remove macro EMPTY_BLOB_SHA1_BIN, as it's no longer used.

struct object_id and adjust all function calls.
Rename this function to hash_object_file.

As long as GIT_SHA1_RAWSZ is equal to GIT_MAX_RAWSZ there's no problem,
but when new hashing algorithm will be in place this memset will clear
only 20-byte prefix of hash buffer.
Alternatively, hashclr implementation could be adjusted, but this
function is almost removed from codebase already. Separate
implementation of oidclr prevents potential buffer overrun in case
someone incorrectly used hashclr on object_id in future.

Convert the definition and declaration of write_notes_tree to
struct object_id and adjust usage of this function.
Additionally, improve style of small part of this function, as old
formatting made it hard to understand at glance what this part of
code is doing.

Convert the definition and declaration of write_sha1_file to
struct object_id and adjust usage of this function.
This commit also converts static function write_sha1_file_prepare, as it
is closely related.
Rename these functions to write_object_file and
write_object_file_prepare respectively.
Replace sha1_to_hex, hashcpy and hashclr with their oid equivalents
wherever possible.

Maybe change the names to oid1 and oid2 too. I had a "what?" moment
when I read hash1->hash below.

You have started the invasion to sha1_file.c. Victory is near! (*)
2018 will be the year of something-other-shan-sha1 :)
I've read through the series quickly. It looks good. Patches 1 and 2
should be sent separately though.
(*) Technically the hashing part is still easy. I look forward to
seeing you deal with the object reading part, especially from pack

I didn't do it originally because the size of hash is explicitly
passed as the third parameter.
I should probably replace this line with:
strbuf_addstr(buf, oid_to_hex(&oid));
... since a hex representation is correctly 0-delimited anyway.
Will include in v3 unless there'll be some other suggestion :)

Yeah I think that's a good idea. This 40 came from 3fed15f568 (Add
'ident' conversion. - 2007-04-21). Back then memcpy was used and 40
made sense. The conversion to strbuf should have used strbuf_addstr()
as you suggested, unless there's performance concerns, but I don't
think there is any.

Unfortunately, I do :(
Few lines above:
192: const struct object_id *oid;
194: oid = tree_entry_extract(&desc, &name, &mode);
Function tree_entry_extract returns const pointer, which leads to
compiler warning:
"assigning to 'struct object_id *' from 'const struct object_id *'
discards qualifiers".
On the other hand, if I change const qualifier for 'rewrite_here'
variable - warning will
appear in line 216:
216: oidcpy(rewrite_here, rewrite_with);
So the question here is rather: is it ok to overwrite buffer returned
by tree_entry_extract?
When writing this I opted to preserve cv-qualifiers despite changing
pointer type (which
implied preservation of typecast) - partly because parameter 'desc' of
tree_entry_extract
is NOT const (which suggests to me, that it's ok).
But this cast might be indication of unintended modification inside
tree description
structure and might lead to an error is some other place, if there's
an assumption, that
this buffer is not overwritable.
Maybe const should be removed from return type of tree_entry_extract (and maybe
from oid field of struct name_entry)?
I will give it some more thought - maybe oidcpy from line 216 could be replaced.

I hoped they could be piggy-backed, but since there will be v3 of this patch
series... I'll wait for Junio's opinion.
> I look forward to seeing you deal with the object reading part …
Yeah, even reading of loose objects does not work on my test branch yet.
Turns out some functions (*) depend on each other during conversion to oid -
so they are either refactored together in one BIG commit or I need to deploy
some temporary hacks to make it possible to split work into smaller batches.
(*) refactor of sha1_object_info transitively depends on lookup_replace_object
and the other way around. verify_object and verify_tag will also cause some
problems.

I've read this code a bit more (sorry I didn't see the "const struct
object_id *oid" line when I read this patch). I think the typecast is
very much on purpose. Junio wanted to make a new tree with one
different hash in 68faf68938 (A new merge stragety 'subtree'. -
2007-02-15) but I think he kinda abused the tree walker for this
task.
A cleaner way is create a new tree by copying unmodified entries and
replacing just one entry. I think the old way was ok when we dealt
with SHA-1 directly, but with the object_id abstraction in place, this
kind of update looks iffy.
Alternatively, perhaps we can do something like this to keep tree
manipulation in tree-walk.c, one of the two places that know about
tree object on-disk format (the other one is cache-tree.c)

Compared to v2:
* rebased to latest master
* patch 1 and 2
I kept them in, but if Junio prefers them separately then I'll send
them as separate patches.
* patch 5
- strbuf_add(buf, sha1_to_hex(oid.hash), GIT_SHA1_HEXSZ);
+ strbuf_addstr(buf, oid_to_hex(&oid));
* patch 7
On suggestion from Duy Nguyễn, I renamed parameter names:
'hash1' and 'hash2' with 'oid1' and 'oid2' to avoid e.g. 'hash1->hash'.
I decided *not to* implement suggested replace_tree_entry_hash
function (when implemented as in mail, t6026-merge-subtree fails).
I think this overwriting of object_id needs to be addressed, but
probably at the time of adjusting tree object format for longer hash.

When git push fails due to server-side WebDAV error, it's not easy to
point to the main culprit. Additional information about exact cURL
error and HTTP server response is helpful for debugging purpose.
New error log helped me pinpoint failing test t5540-http-push-webdav
to a missing Apache dependency in Fedora 27:

The penalty of 5 makes clang-format very eager to put even short type
declarations (e.g. "extern int") into a separate line, even when
breaking parameters list is sufficient.

Convert the declaration of struct sha1_stat. Adjust all usages of this
struct and replace hash{clr,cmp,cpy} with oid{clr,cmp,cpy} wherever
possible. Rename it to struct oid_stat.
Remove macro EMPTY_BLOB_SHA1_BIN, as it's no longer used.

As long as GIT_SHA1_RAWSZ is equal to GIT_MAX_RAWSZ there's no problem,
but when new hashing algorithm will be in place this memset will clear
only 20-byte prefix of hash buffer.
Alternatively, hashclr implementation could be adjusted, but this
function is almost removed from codebase already. Separate
implementation of oidclr prevents potential buffer overrun in case
someone incorrectly used hashclr on object_id in future.

Convert the definition of static recursive splice_tree function to use
struct object_id and adjust single caller.

Convert the definition and declaration of write_notes_tree to
struct object_id and adjust usage of this function.
Additionally, improve style of small part of this function, as old
formatting made it hard to understand at glance what this part of
code is doing.

From: Patryk Obara @ 2018-01-24 11:12 UTC (permalink / raw)
To: git, Junio C Hamano, Nguyễn Thái Ngọc Duy,
brian m . carlson, Jonathan Tan
Convert the definition and declaration of write_sha1_file to
struct object_id and adjust usage of this function.
This commit also converts static function write_sha1_file_prepare, as it
is closely related.
Rename these functions to write_object_file and
write_object_file_prepare respectively.
Replace sha1_to_hex, hashcpy and hashclr with their oid equivalents
wherever possible.

It's not just me, but I think they should be separated out (I can
just queue them separately, and there is no need to resend them
unless/until they need to be updated for their own reason).

OK, but a hunk like this makes readers wonder...

... why the variable is still called sha1_stat, not oid_stat. Is it
because it makes the patch too noisy or something?

These were mostly pleasant read. I'll queue these on two topic

Thank you, everyone, for review and thanks, Junio for queueing two
first patches - I removed them from v4, as there were no more comments
to them anyway.
Compared to v3:
Patch 2 (formerly 4)
- renamed all parameter names sha1_stat to oid_stat
- renamed static function load sha1_stat to load_oid_stat
- adjusted a comment, that included "sha1_stat" in text
Patch 11 (formerly 13)
- fixed a typo in the commit message
Hopefully, this will be the last iteration on this batch of object_id
conversions; I already have next batch prepared (I just need to clean
it up before sending).
Patryk Obara (12):
sha1_file: convert pretend_sha1_file to object_id
dir: convert struct sha1_stat to use object_id
sha1_file: convert hash_sha1_file to object_id
cache: clear whole hash buffer with oidclr
match-trees: convert splice_tree to object_id
commit: convert commit_tree* to object_id
notes: convert combine_notes_* to object_id
notes: convert write_notes_tree to object_id
sha1_file: convert write_sha1_file to object_id
sha1_file: convert force_object_loose to object_id
sha1_file: convert write_loose_object to object_id
sha1_file: rename hash_sha1_file_literally

Convert the declaration and definition of pretend_sha1_file to use
struct object_id and adjust all usages of this function. Rename it to
pretend_object_file.

Convert the declaration of struct sha1_stat. Adjust all usages of this
struct and replace hash{clr,cmp,cpy} with oid{clr,cmp,cpy} wherever
possible. Rename it to struct oid_stat.
Rename static function load_sha1_stat to load_oid_stat.
Remove macro EMPTY_BLOB_SHA1_BIN, as it's no longer used.

As long as GIT_SHA1_RAWSZ is equal to GIT_MAX_RAWSZ there's no problem,
but when new hashing algorithm will be in place this memset will clear
only 20-byte prefix of hash buffer.
Alternatively, hashclr implementation could be adjusted, but this
function is almost removed from codebase already. Separate
implementation of oidclr prevents potential buffer overrun in case
someone incorrectly used hashclr on object_id in future.

Convert the definition and declaration of write_notes_tree to
struct object_id and adjust usage of this function.
Additionally, improve style of small part of this function, as old
formatting made it hard to understand at glance what this part of
code is doing.

Convert the definition and declaration of write_sha1_file to
struct object_id and adjust usage of this function.
This commit also converts static function write_sha1_file_prepare, as it
is closely related.
Rename these functions to write_object_file and
write_object_file_prepare respectively.
Replace sha1_to_hex, hashcpy and hashclr with their oid equivalents
wherever possible.
