* Support getting changed files when commit ID is `EmptySHA` (#26290)Zettat1232023-08-041-1/+9
| | | | | | | | | | | | | | | | | | | | Fixes #26270. Co-Author: @wxiaoguang Thanks @lunny for providing this solution As https://github.com/go-gitea/gitea/issues/26270#issuecomment-1661695151 said, at present we cannot get the names of changed files correctly when the `OldCommitID` is `EmptySHA`. In this PR, the `GetCommitFilesChanged` method is added and will be used to get the changed files by commit ID.

* Add git dashes separator to some "log" and "diff" commands (#23606)wxiaoguang2023-03-261-3/+7
| | | | | | | | | | | | | | | | | 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.
* Fix GetFilesChangedBetween if the file name may be escaped (#23272)zeripath2023-03-031-2/+9
| | | | | | | | | | | | | The code for GetFilesChangedBetween uses `git diff --name-only base..head` to get the names of files changed between base and head however this forgets that git will escape certain values. This PR simply switches to use `-z` which has the `NUL` character as the separator.

* Refactor git command package to improve security and maintainability (#22678)wxiaoguang2023-02-041-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. --------- Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>

* Set no-tags in git fetch on compare (#20893)zeripath2022-08-231-1/+1
| | | | | | | | | | | | | | | | | | | * Set no-tags in git fetch on compare In the compare endpoint the git fetch is restricted to a certain branch however, this does not completely prevent tag acquisition/pollution as git fetch will collect any tags on that branch. This causes pollution of the tag namespace and could cause confusion by users. This PR adds `--no-tags` to the `git fetch` call.

However, we can improve things using `git read-tree -m` to do a three-way merge then follow the algorithm used in merge-one-file. We can also use `--patience` and/or `--histogram` to generate a nicer diff for applying patches too. Fix #13679 Fix #6417 Signed-off-by: Andrew Thornton <art27@cantab.net>
