Remove redundant nil check in `WalkGitLog` (#26773)
From the Go specification:
> "1. For a nil slice, the number of iterations is 0."
https://go.dev/ref/spec#For_range
Therefore, an additional nil check for before the 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.

Close stdout correctly for "git blame", otherwise the failed "git blame"
would case the request hanging forever.
And "os.Stderr" should never (seldom) be used as git command's stderr
Make git batch operations use parent context timeout instead of default timeout (#26325)
Fix #26064
Some git commands should use parent context, otherwise it would exit too
early (by the default timeout, 10m), and the "cmd.Wait" waits till the
pipes are closed.
The `FileBlame` function looks strange, it has `revision` as argument
but doesn't use it.
Since the function never be used, I think we could just remove it.
If anyone thinks it should be kept, please help fix `revision`.

Use the type RefName for all the needed places and fix pull mirror sync bugs (#24634)
This PR replaces all string refName as a type `git.RefName` to make the
code more maintainable.
Fix #15367
Replaces #23070
It also fixed a bug that tags are not sync because `git remote --prune
origin` will not remove local tags if remote removed.
We in fact should use `git fetch --prune --tags origin` but not `git
remote update origin` to do the sync.
Some answer from ChatGPT as ref.
> If the git fetch --prune --tags command is not working as expected,
there could be a few reasons why. Here are a few things to check:
>
>Make sure that you have the latest version of Git installed on your
system. You can check the version by running git --version in your
terminal. If you have an outdated version, try updating Git and see if
that resolves the issue.
>
>Check that your Git repository is properly configured to track the
remote repository's tags. You can check this by running git config
--get-all remote.origin.fetch and verifying that it includes
+refs/tags/*:refs/tags/*. If it does not, you can add it by running git
config --add remote.origin.fetch "+refs/tags/*:refs/tags/*".
>
>Verify that the tags you are trying to prune actually exist on the
remote repository. You can do this by running git ls-remote --tags
origin to list all the tags on the remote repository.
>
>Check if any local tags have been created that match the names of tags
on the remote repository. If so, these local tags may be preventing the
git fetch --prune --tags command from working properly. You can delete
local tags using the git tag -d command.

Merge different languages for language stats (#24900)
Fix #24896
If users set different languages by `linguist-language`, the `stats` map
could be: `java: 100, Java: 200`.
Language stats are stored as case-insensitive in database and there is a
unique key.
So, the different language names should be merged to one unique name:
`Java: 300`
Support changing git config through `app.ini`, use `diff.algorithm=histogram` by default (#24860)

Many users have the requirement to customize the git config. This PR
introduces an easy way: put the options in Gitea's app.ini
`[git.config]`, then the config options will be applied to git config.
And it can support more flexible default config values, eg: now
`diff.algorithm=histogram` by default. According to:
https://stackoverflow.com/a/32367597/4754037 , `histogram diff` is
efficient and doesn't like to cause server-side problems.

## ⚠️ 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.

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
Add ability to specify '--not' from GetAllCommits (#24409)
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`
command to allow the user to exclude items from `GetAllCommits`.
See [git
documentation](https://git-scm.com/docs/git-log#Documentation/git-log.txt---not)

Make wiki title supports dashes and improve wiki name related features (#24143)
Close #7570
1. Clearly define the wiki path behaviors, see
`services/wiki/wiki_path.go` and tests
2. Keep compatibility with old contents
3. Allow to use dashes in titles, eg: "2000-01-02 Meeting record"
4. Add a "Pages" link in the dropdown, otherwise users can't go to the
Pages page easily.
5. Add a "View original git file" link in the Pages list, even if some
file names are broken, users still have a chance to edit or remove it,
without cloning the wiki repo to local.
6. Fix 500 error when the name contains prefix spaces.
This PR also introduces the ability to support sub-directories, but it
can't be done at the moment due to there are a lot of legacy wiki data,
which use "%2F" in file names.

Add git dashes separator to some "log" and "diff" commands (#23606)
Reference:
https://github.com/go-gitea/gitea/issues/22578#issuecomment-1444180053
Credits to @tdesveaux , thank you very much for catching the problem. If
you'd like to open a PR, feel free to replace this one.
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.
Handle files starting with colons in WalkGitLog (#22935)
Currently gitea shows no commit information for files starting with a
colon.
[I set up a minimal repro repository that reproduces this error once
it's migrated on gitea](https://github.com/kbolashev/colon-test)
<img width="1209" alt="image"
src="https://user-images.githubusercontent.com/111061261/219326625-0e6d3a86-8b58-4d67-bc24-8a78963f36b9.png">
This is happening because the filenames piped to the `git log` command
are written as is, and it doesn't work when you have a colon at the
start of the filename, and you need to escape it.
You can test it locally, if you do
```
mkdir repo
git init
touch :file
git add . && git commit -m "Add file with colon"
git log -- :file
```
git log returns nothing. However, if you do `git log -- "\:file"`, it
will show the commit with the file change.
This PR escapes the starting colons in paths in the `LogNameStatusRepo`
function, making gitea return commit info about the file with the bad
filename.
<img width="1209" alt="image"
src="https://user-images.githubusercontent.com/111061261/219328299-46451246-4006-45e3-89b1-c244635ded23.png">
This error shows up only with files starting with colon, anywhere else
in filename is ok. Dashes at the beginning also seem to be working.
I don't know gitea internals well enough to know where else this error
can pop up, so I'm keeping this PR small as suggested by your
contributor guide
This PR adds support for reflogs on all repositories. It does this by
adding a global configuration entry.

Fix pull request update showing too many commits with multiple branches (#22856)
When the base repository contains multiple branches with the same
commits as the base branch, pull requests can show a long list of
commits already in the base branch as having been added.
What this is supposed to do is exclude commits already in the base
branch. But the mechansim to do so assumed a commit only exists in a
single branch. Now use `git rev-list A B --not branchName` instead of
filtering commits afterwards.
The logic to detect if there was a force push also was wrong for
multiple branches. If the old commit existed in any branch in the base
repository it would assume there was no force push. Instead check if the
old commit is an ancestor of the new commit.
Follow #22568
* Remove unnecessary ToTrustedCmdArgs calls
* the FAQ in #22678
* Quote: When using ToTrustedCmdArgs, the code will be very complex (see
the changes for examples). Then developers and reviewers can know that
something might be unreasonable.
* The `signArg` couldn't be empty, it's either `-S{keyID}` or
`--no-gpg-sign`.
* Use `signKeyID` instead, add comment "empty for no-sign, non-empty to
sign"
* 5-line code could be extracted to a common `NewGitCommandCommit()` to
handle the `signKeyID`, but I think it's not a must, current code is
clear enough.
Refactor and tidy-up the merge/update branch code (#22568)
The merge and update branch code was previously a little tangled and had
some very long functions. The functions were not very clear in their
reasoning and there were deficiencies in their logging and at least one
bug in the handling of LFS for update by rebase.
This PR substantially refactors this code and splits things out to into
separate functions. It also attempts to tidy up the calls by wrapping
things in "context"s. There are also attempts to improve logging when
there are errors.

Fix GetFilesChangedBetween if the file name may be escaped (#23272)
The code for GetFilesChangedBetween uses `git diff --name-only

however this forgets that git will escape certain values.
This PR simply switches to use `-z` which has the `NUL` character as the

This arose out of #22451; it seems we are checking using non-global

call another global(-indeed) configuration command. This PR changes it

Use `--message=%s` for git commit message (#23028)
Close #23027
`git commit` message option _only_ supports 4 formats (well, only ....):
* `"commit", "-m", msg`
* `"commit", "-m{msg}"` (no space)
* `"commit", "--message", msg`
* `"commit", "--message={msg}"`
The long format with `=` is the best choice, and it's documented in `man
git-commit`:
`-m <msg>, --message=<msg> ...`
ps: I would suggest always use long format option for git command, as
much as possible.

Remember to attach the parent tree when converting TreeEntry() -> Tree() (#22902)
!fixup https://github.com/go-gitea/gitea/pull/22177
The only place this function is used so far is in
findReadmeFileInEntries(), so the only visible effect of this oversight
was in an obscure README-related corner: if the README was in a
subfolder and was a symlink that pointed up, as in .github/README.md ->
../docs/old/setup.md, the README would fail to render when FollowLinks()
hit the nil ptree. This makes the ptree non-nil and thus repairs it.
This code was copy-pasted at some point. Revisit it to reunify it.
~~Doing that then encouraged simplifying the types of a couple of
related functions.~~
~~As a follow-up, move two helper functions, `isReadmeFile()` and
`isReadmeFileExtension()`, intimately tied to `findReadmeFile()`, in as
package-private.~~

During the refactoring of the git module, I found there were some
strange operations. This PR tries to fix 2 of them
1. The empty argument `--` in repo_attribute.go, which was introduced by
#16773. It seems unnecessary because nothing else would be added later.
2. The complex git service logic in repo/http.go.
* Before: the `hasAccess` only allow `service == "upload-pack" ||
service == "receive-pack"`
* After: unrelated code is removed. No need to call ToTrustedCmdArgs
anymore.

Refactor git command package to improve security and maintainability (#22678)
This PR follows #21535 (and replace #22592)
## Review without space diff
https://github.com/go-gitea/gitea/pull/22678/files?diff=split&w=1
## Purpose of this PR
1. Make git module command completely safe (risky user inputs won't be
passed as argument option anymore)
2. Avoid low-level mistakes like
https://github.com/go-gitea/gitea/pull/22098#discussion_r1045234918
3. Remove deprecated and dirty `CmdArgCheck` function, hide the `CmdArg`
type
4. Simplify code when using git command
## The main idea of this PR
* Move the `git.CmdArg` to the `internal` package, then no other package
except `git` could use it. Then developers could never do
`AddArguments(git.CmdArg(userInput))` any more.
* Introduce `git.ToTrustedCmdArgs`, it's for user-provided and already
trusted arguments. It's only used in a few cases, for example: use git
arguments from config file, help unit test with some arguments.
* Introduce `AddOptionValues` and `AddOptionFormat`, they make code more
clear and simple:
* Before: `AddArguments("-m").AddDynamicArguments(message)`
* After: `AddOptionValues("-m", message)`
* -
* Before: `AddArguments(git.CmdArg(fmt.Sprintf("--author='%s <%s>'",
sig.Name, sig.Email)))`
* After: `AddOptionFormat("--author='%s <%s>'", sig.Name, sig.Email)`
## FAQ
### Why these changes were not done in #21535 ?
#21535 is mainly a search&replace, it did its best to not change too
much logic.
Making the framework better needs a lot of changes, so this separate PR
is needed as the second step.
### The naming of `AddOptionXxx`
According to git's manual, the `--xxx` part is called `option`.
### How can it guarantee that `internal.CmdArg` won't be not misused?
Go's specification guarantees that. Trying to access other package's
internal package causes compilation error.
And, `golangci-lint` also denies the git/internal package. Only the
`git/command.go` can use it carefully.
### There is still a `ToTrustedCmdArgs`, will it still allow developers
to make mistakes and pass untrusted arguments?
Generally speaking, no. Because when using `ToTrustedCmdArgs`, the code
will be very complex (see the changes for examples). Then developers and
reviewers can know that something might be unreasonable.
### Why there was a `CmdArgCheck` and why it's removed?
At the moment of #21535, to reduce unnecessary changes, `CmdArgCheck`
was introduced as a hacky patch. Now, almost all code could be written
as `cmd := NewCommand(); cmd.AddXxx(...)`, then there is no need for
`CmdArgCheck` anymore.
### Why many codes for `signArg == ""` is deleted?
Because in the old code, `signArg` could never be empty string, it's
either `-S[key-id]` or `--no-gpg-sign`. So the `signArg == ""` is just
dead code.
