From 568f013e762423fc54a8fb1daed1e7b59c1dc0f0 Mon Sep 17 00:00:00 2001 From: Sebastian Thiel Date: Thu, 21 Apr 2022 11:25:34 +0800 Subject: [PATCH 001/120] change!: `Pattern::matches()` is now private (#301) It doesn't work as one would expect due to it wanting to match relative paths only. Thus it's better to spare folks the surprise and instead use `wildmatch()` directly. It works the same, but doesn't have certain shortcuts which aren't needed for standard matches anyway. --- git-glob/src/lib.rs | 6 ++++-- git-glob/src/parse.rs | 6 +++--- git-glob/src/pattern.rs | 35 ++++++++++----------------------- git-glob/tests/matching/mod.rs | 11 +++++++---- git-glob/tests/parse/mod.rs | 4 ++-- git-glob/tests/wildmatch/mod.rs | 7 +++++-- 6 files changed, 31 insertions(+), 38 deletions(-) diff --git a/git-glob/src/lib.rs b/git-glob/src/lib.rs index 847600a71a2..c7b9df920d7 100644 --- a/git-glob/src/lib.rs +++ b/git-glob/src/lib.rs @@ -4,9 +4,9 @@ use bstr::BString; -/// A glob pattern at a particular base path. +/// A glob pattern optimized for matching paths relative to a root directory. /// -/// This closely models how patterns appear in a directory hierarchy of include or attribute files. +/// For normal globbing, use [`wildmatch()`] instead. #[derive(PartialEq, Eq, Debug, Hash, Ord, PartialOrd, Clone)] #[cfg_attr(feature = "serde1", derive(serde::Serialize, serde::Deserialize))] pub struct Pattern { @@ -28,6 +28,8 @@ pub use wildmatch::function::wildmatch; mod parse; /// Create a [`Pattern`] by parsing `text` or return `None` if `text` is empty. +/// +/// Note that pub fn parse(text: &[u8]) -> Option { Pattern::from_bytes(text) } diff --git a/git-glob/src/parse.rs b/git-glob/src/parse.rs index d39140438c7..3693f88efcb 100644 --- a/git-glob/src/parse.rs +++ b/git-glob/src/parse.rs @@ -26,6 +26,7 @@ pub fn pattern(mut pat: &[u8]) -> Option<(BString, pattern::Mode, Option) } if pat.first() == Some(&b'/') { mode |= Mode::ABSOLUTE; + pat = &pat[1..]; } let mut pat = truncate_non_escaped_trailing_spaces(pat); if pat.last() == Some(&b'/') { @@ -33,11 +34,10 @@ pub fn pattern(mut pat: &[u8]) -> Option<(BString, pattern::Mode, Option) pat.pop(); } - let relative_pattern = mode.contains(Mode::ABSOLUTE).then(|| &pat[1..]).unwrap_or(&pat); - if !relative_pattern.contains(&b'/') { + if !pat.contains(&b'/') { mode |= Mode::NO_SUB_DIR; } - if relative_pattern.first() == Some(&b'*') && first_wildcard_pos(&relative_pattern[1..]).is_none() { + if pat.first() == Some(&b'*') && first_wildcard_pos(&pat[1..]).is_none() { mode |= Mode::ENDS_WITH; } diff --git a/git-glob/src/pattern.rs b/git-glob/src/pattern.rs index 14fb4f6658f..fa59500963a 100644 --- a/git-glob/src/pattern.rs +++ b/git-glob/src/pattern.rs @@ -84,20 +84,15 @@ impl Pattern { ); debug_assert!(!path.starts_with(b"/"), "input path must be relative"); - let (text, first_wildcard_pos) = self - .mode - .contains(pattern::Mode::ABSOLUTE) - .then(|| (self.text[1..].as_bstr(), self.first_wildcard_pos.map(|p| p - 1))) - .unwrap_or((self.text.as_bstr(), self.first_wildcard_pos)); if self.mode.contains(pattern::Mode::NO_SUB_DIR) { let basename = if self.mode.contains(pattern::Mode::ABSOLUTE) { path } else { &path[basename_start_pos.unwrap_or_default()..] }; - self.matches_inner(text, first_wildcard_pos, basename, flags) + self.matches(basename, flags) } else { - self.matches_inner(text, first_wildcard_pos, path, flags) + self.matches(path, flags) } } @@ -107,22 +102,12 @@ impl Pattern { /// strings with cases ignored as well.

However, we are dependent on the order of operations and assume properly ordered input which can't be assumed for things like check-ignore and can probably lead to strange bugs if some users don't know about that. There should be a fix for that. --- git-worktree/src/fs/cache/mod.rs | 28 +++++++++++++++++-- git-worktree/src/fs/cache/platform.rs | 7 ++--- git-worktree/src/index/entry.rs | 9 +++--- .../make_ignore_and_attributes_setup.sh | 1 - git-worktree/tests/worktree/fs/cache.rs | 21 ++++++-------- 5 files changed, 42 insertions(+), 24 deletions(-) diff --git a/git-worktree/src/fs/cache/mod.rs b/git-worktree/src/fs/cache/mod.rs index 386a5bf41ad..976da23e6a3 100644 --- a/git-worktree/src/fs/cache/mod.rs +++ b/git-worktree/src/fs/cache/mod.rs @@ -1,6 +1,7 @@ use super::Cache; use crate::fs; use crate::fs::PathOidMapping; +use bstr::{BStr, ByteSlice}; use git_hash::oid; use std::path::{Path, PathBuf}; @@ -84,7 +85,7 @@ impl<'paths> Cache<'paths> { /// path is created as directory.

(#301) This allows for generic types for sources of errors and allows to workaround a limitation with associated type constraints in the MSRV of 1.54. Using thiserror makes this work and brings the crate more closely to the rest of the gitoxide crates (which now prefer thiserror over quickerror). --- Cargo.lock | 2 +- git-config/Cargo.toml | 2 +- git-config/src/file/git_config.rs | 113 +++++++++--------------- git-config/src/file/section.rs | 14 +-- git-config/src/fs.rs | 20 +---- git-config/src/lib.rs | 48 ++++------ git-config/src/values.rs | 135 +++++++++++++---------------- git-config/tests/git_config/mod.rs | 2 +- 8 files changed, 131 insertions(+), 205 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 342ff9b6eeb..515d4f4106a 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1138,11 +1138,11 @@ dependencies = [ "memchr", "nom", "pwd", - "quick-error", "serde", "serde_derive", "serial_test", "tempfile", + "thiserror", "unicode-bom", ] diff --git a/git-config/Cargo.toml b/git-config/Cargo.toml index 8078167fdfa..f4c67d83591 100644 --- a/git-config/Cargo.toml +++ b/git-config/Cargo.toml @@ -23,7 +23,7 @@ nom = { version = "7", default_features = false, features = [ "std" ] } memchr = "2" serde_crate = { version = "1", package = "serde", optional = true } pwd = "1.3.1" -quick-error = "2.0.0" +thiserror = "1.0.26" unicode-bom = "1.1.4" bstr = { version = "0.2.13", default-features = false, features = ["std"] } diff --git a/git-config/src/file/git_config.rs b/git-config/src/file/git_config.rs index 68e489a1d09..15e5f3de725 100644 --- a/git-config/src/file/git_config.rs +++ b/git-config/src/file/git_config.rs @@ -120,32 +120,20 @@ pub struct GitConfig<'event> { pub mod from_paths { use std::borrow::Cow;

(#301) If and only if it canonicalized the source path. That way, users will still get a familiar path. This is due to `parent()` not operating in the file system, which otherwise would be equivalent to `..`, but that's not how we work. Maybe we should overhaul the way this works to use `../` instead and just 'absoluteize' the path later (std::path::absolute()) is on the way for that. --- git-path/src/convert.rs | 2 + git-repository/src/path/discover.rs | 73 +++++++++++++++++++--------- git-repository/src/path/is.rs | 1 + git-repository/src/path/mod.rs | 6 ++- git-repository/tests/discover/mod.rs | 11 ++--- 5 files changed, 62 insertions(+), 31 deletions(-) diff --git a/git-path/src/convert.rs b/git-path/src/convert.rs index 4d5ce684555..5c2853aae45 100644 --- a/git-path/src/convert.rs +++ b/git-path/src/convert.rs @@ -183,6 +183,7 @@ pub fn to_unix_separators_on_windows<'a>(path: impl Into>) -> Cow< /// Replaces windows path separators with slashes, unconditionally. /// /// **Note** Do not use these and prefer the conditional versions of this method. +// TODO: use https://lib.rs/crates/path-slash to handle escapes pub fn to_unix_separators<'a>(path: impl Into>) -> Cow<'a, BStr> { replace(path, b'\\', b'/') } @@ -190,6 +191,7 @@ pub fn to_unix_separators<'a>(path: impl Into>) -> Cow<'a, BStr> { /// Find backslashes and replace them with slashes, which typically resembles a unix path, unconditionally. /// /// **Note** Do not use these and prefer the conditional versions of this method. +// TODO: use https://lib.rs/crates/path-slash to handle escapes pub fn to_windows_separators<'a>(path: impl Into>) -> Cow<'a, BStr> { replace(path, b'/', b'\\') } diff --git a/git-repository/src/path/discover.rs b/git-repository/src/path/discover.rs index 1ebd0184ff8..1ce7ae2c736 100644 --- a/git-repository/src/path/discover.rs +++ b/git-repository/src/path/discover.rs @@ -8,6 +8,12 @@ pub enum Error { InaccessibleDirectory { path: PathBuf }, #[error("Could find a git repository in '{}' or in any of its parents", .path.display())] NoGitRepository { path: PathBuf }, + #[error("Could find a trusted git repository in '{}' or in any of its parents, candidate at '{}' discarded", .path.display(), .candidate.display())] + NoTrustedGitRepository { + path: PathBuf, + candidate: PathBuf, + required: git_sec::Trust, + }, #[error("Could not determine trust level for path '{}'.", .path.display())] CheckTrust { path: PathBuf, @@ -37,6 +43,7 @@ impl Default for Options { pub(crate) mod function { use super::{Error, Options}; use git_sec::Trust; + use std::path::PathBuf; use std::{ borrow::Cow, path::{Component, Path}, @@ -57,23 +64,20 @@ pub(crate) mod function { // us the parent directory.
