Lazy load object format with command line and don't do it in OpenRepository (#29712)
Most time, when invoking `git.OpenRepository`, `objectFormat` will not
be used, so it's a waste to invoke commandline to get the object format.
This PR make it a lazy operation, only invoke that when necessary.

Add a check for when the command is canceled by the program on Window… (#29538)
Close #29509

Windows, unlike Linux, does not have signal-specified exit codes.
Therefore, we should add a Windows-specific check for Windows. If we
don't do this, the logs will always show a failed status, even though
the command actually works correctly.

If you check the Go source code in exec_windows.go, you will see that it
always returns exit code 1.

![image](https://github.com/go-gitea/gitea/assets/30816317/9dfd7c70-9995-47d9-9641-db793f58770c)

The exit code 1 does not exclusively signify a SIGNAL KILL; it can
indicate any issue that occurs when a program fails.

Prevent double use of `git cat-file` session. (#29298)
Fixes the reason why #29101 is hard to replicate.
Related #29297

Create a repo with a file with minimum size 4097 bytes (I use 10000) and
execute the following code:
```go
gitRepo, err := gitrepo.OpenRepository(db.DefaultContext, <repo>)
assert.NoError(t, err)

commit, err := gitRepo.GetCommit(<sha>)
assert.NoError(t, err)

entry, err := commit.GetTreeEntryByPath(<file>)
assert.NoError(t, err)

b := entry.Blob()

// Create a reader
r, err := b.DataAsync()
assert.NoError(t, err)
defer r.Close()

// Create a second reader
r2, err := b.DataAsync()
assert.NoError(t, err) // Should be no error but is ErrNotExist
defer r2.Close()
```

The problem is the check in `CatFileBatch`:

79217ea63c/modules/git/repo_base_nogogit.go (L81-L87)
`Buffered() > 0` is used to check if there is a "operation" in progress
at the moment. This is a problem because we can't control the internal
buffer in the `bufio.Reader`. The code above demonstrates a sequence
which initiates an operation for which the code thinks there is no
active processing. The second call to `DataAsync()` therefore reuses the
existing instances instead of creating a new batch reader.

Add merge style `fast-forward-only` (#28954)
With this option, it is possible to require a linear commit history with

The original commits continue existing, with the original signatures
continuing to stay valid instead of being rewritten, there is no merge
commit, and reverting commits becomes easier.

Simplify how git repositories are opened (#28937)
## Purpose
This is a refactor toward building an abstraction over managing git
repositories.
Afterwards, it does not matter anymore if they are stored on the local
disk or somewhere remote.

## What this PR changes
We used `git.OpenRepository` everywhere previously.
Now, we should split them into two distinct functions:

Firstly, there are temporary repositories which do not change:

```go
git.OpenRepository(ctx, diskPath)
```

Gitea managed repositories having a record in the database in the
`repository` table are moved into the new package `gitrepo`:

```go
gitrepo.OpenRepository(ctx, repo_model.Repo)
```

Why is `repo_model.Repository` the second parameter instead of file
path?
Because then we can easily adapt our repository storage strategy.
The repositories can be stored locally, however, they could just as well
be stored on a remote server.

## Further changes in other PRs
- A Git Command wrapper on package `gitrepo` could be created. i.e.
`NewCommand(ctx, repo_model.Repository, commands...)`. `git.RunOpts{Dir:
repo.RepoPath()}`, the directory should be empty before invoking this
method and it can be filled in the function only. #28940
- Remove the `RepoPath()`/`WikiPath()` functions to reduce the
possibility of mistakes.

Check for sha256 support to use --object-format flag (#28928)
This should fix https://github.com/go-gitea/gitea/issues/28927

Technically older versions of Git would support this flag as well, but
per https://github.com/go-gitea/gitea/pull/28466 that's the version
where using it (object-format=sha256) left "experimental" state.

`sha1` is (currently) the default, so older clients should be unaffected
in either case.

Fix archive creating LFS hooks and breaking pull requests (#28848)
When LFS hooks are present in gitea-repositories, operations like git
push for creating a pull request fail. These repositories are not meant
to include LFS files or git push them, that is handled separately. And
so they should not have LFS hooks.

Installing git-lfs on some systems (like Debian Linux) will
automatically set up /etc/gitconfig to create LFS hooks in repositories.
For most git commands in Gitea this is not a problem, either because
they run on a temporary clone or the git command does not create LFS
hooks.

But one case where this happens is git archive for creating repository
archives. To fix that, add a GIT_CONFIG_NOSYSTEM=1 to disable using the
system configuration for that command.

According to a comment, GIT_CONFIG_NOSYSTEM is not used for all git
commands because the system configuration can be intentionally set up
for Gitea to use.

Add -F to commit search to treat keywords as strings (#28744)
Fixes #28269

The [default
behavior](https://git-scm.com/docs/git-log#Documentation/git-log.txt---basic-regexp)
of --grep in git log is to interpret the keyword as a regular
expression. This causes the search to fail in the cases where the search
keyword contains a `[`, since `[` is a special character used in grep.

If we want our keywords to be interpreted as 'strings', we should use
[-F
flag](https://git-scm.com/docs/git-log#Documentation/git-log.txt---basic-regexp).

Always enable caches (#28527)
Nowadays, cache will be used on almost everywhere of Gitea and it cannot

But of course, we can still use cache configuration to set how should
Gitea use the cache.

Improve ObjectFormat interface (#28496)
The 4 functions are duplicated, especially as interface methods. I think
we just need to keep `MustID` the only one and remove other 3.

```
MustID(b []byte) ObjectID
MustIDFromString(s string) ObjectID
NewID(b []byte) (ObjectID, error)
NewIDFromString(s string) (ObjectID, error)
```

Introduced the new interfrace method `ComputeHash` which will replace
the interface `HasherInterface`. Now we don't need to keep two
interfaces.

Reintroduced `git.NewIDFromString` and `git.MustIDFromString`. The new
function will detect the hash length to decide which objectformat of it.
If it's 40, then it's SHA1. If it's 64, then it's SHA256. This will be
right if the commitID is a full one. So the parameter should be always a
full commit id.

PS: perhaps it's a good idea to use

somewhere because the assert package's default behavior does not exit
when an error occurs, which makes it difficult to find the root error
reason.

Remove redundant `len` check around loop (#27464)
This pull request is a minor code cleanup.

From the Go specification (https://go.dev/ref/spec#For_range):

> "1. For a nil slice, the number of iterations is 0."
> "3. If the map is nil, the number of iterations is 0."

`len` returns 0 if the slice or map is nil
(https://pkg.go.dev/builtin#len). Therefore, checking `len(v) > 0`
before a loop is unnecessary.

Add merge files files to GetCommitFileStatus (#20515)
Hi,

We'd like to add merge files files to GetCommitFileStatus fucntions so
API returns the list of all the files associated to a merged pull
request commit, like GitHub API does.
The list of affectedFiles for an API commit is fetched from toCommit()
function in routers/api/v1/repo/commits.go, and API was returning no
file in case of a pull request with no conflict, or just files
associated to the confict resolution, but NOT the full list of merged
files.

This would lead to situations where a CI polling a repo for changes
could miss some file changes due to API returning an empty / partial
list in case of such merged pull requests. (Hope this makes sense :) )

NOTE: I'd like to add a unittest in
integrations/api_repo_git_commits_test.go but failed to understand how
to add my own test bare repo so I can make a test on a merged pull
request commit to check for affectedFiles.
Is there a merged pull request in there that I could use maybe?
Could someone please direct me to the relevant ressources with
informations on how to do that please?

Thanks for your time,
Laurent.
