- The parser of `git grep`'s output uses `bufio.Scanner`, which is a good
choice overall, however it does have a limit that's usually not noticed,
it will not read more than `64 * 1024` bytes at once which can be hit in
practical scenarios.
- Use `bufio.Reader` instead which doesn't have this limitation, but is
a bit harder to work with as it's a more lower level primitive.
- Adds unit test.
- Resolves https://codeberg.org/forgejo/forgejo/issues/3149
- `%w` is to wrap errors, but can only be used by `fmt.Errorf`. Instead
use `%v` to display the error.

`CommitGPGSignature` was originally made to store information about a
commit's GPG signature. Nowadays, it is used to store information about
SSH signatures too, and not just commit signatures, but tag signatures
too.
As such, rename it to `ObjectSignature`, because that describes what it
does a whole lot better.

Just like commits, tags can be signed with either an OpenPGP, or with an
SSH key. While the latter is supported already, SSH-signed tags have not
been. This patch teaches the git module to recognize and handle
SSH-signed tags too.
This will stop the signatures appearing in release notes, but are
currently unused otherwise.

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.

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

defer r.Close()
// Create a second reader

```
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.

The test suite was broken e.g. on Debian 12 due to requiring a very
recent version of Git installed on the system. This commit skips SHA256
tests in the git module, if a Git version older than 2.42 or gogit is used.
With this option, it is possible to require a linear commit history with
the following benefits over the next best option `Rebase+fast-forward`:
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.
Closes#24906
- In Git version v2.43.1, the behavior of `GIT_FLUSH` was accidentially

`GIT_FLUSH=0` thus getting the correct behavior.

## 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.

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

`sha1` is (currently) the default, so older clients should be unaffected

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.
Resolves#19810, #21148
Nowadays, cache will be used on almost everywhere of Gitea and it cannot
be disabled, otherwise some features will become unaviable.
Then I think we can just remove the option for cache enable. That means
cache cannot be disabled.
But of course, we can still use cache configuration to set how should
Gitea use the cache.
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.
@AdamMajer Please review.
Update golang.org/x/crypto for CVE-2023-48795 and update other packages.
`go-git` is not updated because it needs time to figure out why some
tests fail.
- Remove `ObjectFormatID`
- Remove function `ObjectFormatFromID`.
- Use `Sha1ObjectFormat` directly but not a pointer because it's an
empty struct.
- Store `ObjectFormatName` in `repository` struct
Refactor Hash interfaces and centralize hash function. This will allow
easier introduction of different hash function later on.
This forms the "no-op" part of the SHA256 enablement patch.
The summary string ends up in the database, and (at least) MySQL &
PostgreSQL require valid UTF8 strings.

assert.Fail() will continue to execute the code while assert.FailNow()
not. I thought those uses of assert.Fail() should exit immediately.
PS: perhaps it's a good idea to use
[require](https://pkg.go.dev/github.com/stretchr/testify/require)
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.
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.

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.

## ⚠️ Breaking
The `log.<mode>.<logger>` style config has been dropped. If you used it,
please check the new config manual & app.example.ini to make your
instance output logs as expected.
Although many legacy options still work, it's encouraged to upgrade to
the new options.
The SMTP logger is deleted because SMTP is not suitable to collect logs.
If you have manually configured Gitea log options, please confirm the
logger system works as expected after upgrading.
## Description
Close#12082 and maybe more log-related issues, resolve some related
FIXMEs in old code (which seems unfixable before)
Just like rewriting queue #24505 : make code maintainable, clear legacy
bugs, and add the ability to support more writers (eg: JSON, structured
log)
There is a new document (with examples): `logging-config.en-us.md`
This PR is safer than the queue rewriting, because it's just for
logging, it won't break other logic.
## The old problems
The logging system is quite old and difficult to maintain:
* Unclear concepts: Logger, NamedLogger, MultiChannelledLogger,
SubLogger, EventLogger, WriterLogger etc
* Some code is diffuclt to konw whether it is right:
`log.DelNamedLogger("console")` vs `log.DelNamedLogger(log.DEFAULT)` vs
`log.DelLogger("console")`
* The old system heavily depends on ini config system, it's difficult to
create new logger for different purpose, and it's very fragile.
* The "color" trick is difficult to use and read, many colors are
unnecessary, and in the future structured log could help
* It's difficult to add other log formats, eg: JSON format
* The log outputer doesn't have full control of its goroutine, it's
difficult to make outputer have advanced behaviors
* The logs could be lost in some cases: eg: no Fatal error when using
CLI.
* Config options are passed by JSON, which is quite fragile.
* INI package makes the KEY in `[log]` section visible in `[log.sub1]`
and `[log.sub1.subA]`, this behavior is quite fragile and would cause
more unclear problems, and there is no strong requirement to support
`log.<mode>.<logger>` syntax.
## The new design
See `logger.go` for documents.
## Screenshot

* [x] add some new tests

Due to #24409 , we can now specify '--not' when getting all commits from
a repo to exclude commits from a different branch.
When I wrote that PR, I forgot to also update the code that counts the
number of commits in the repo. So now, if the --not option is used, it
may return too many commits, which can indicate that another page of
data is available when it is not.
This PR passes --not to the commands that count the number of commits in
a repo
For my specific use case, I'd like to get all commits that are on one
branch but NOT on the other branch.
For instance, I'd like to get all the commits on `Branch1` that are not
also on `master` (I.e. all commits that were made after `Branch1` was
created).
This PR adds a `not` query param that gets passed down to the `git log`

Git reports fatal errors for ambiguous arguments:
```
fatal: ambiguous argument 'refs/a...refs/b': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
```
So the `--` separator is necessary in some cases.
