The test-local fetch error converts the same way. --- Cargo.lock | 1 - gix-protocol/Cargo.toml | 1 - gix-protocol/src/command.rs | 19 +++- gix-protocol/src/fetch/error.rs | 109 +++++++++++++++++++---- gix-protocol/src/fetch/negotiate.rs | 83 ++++++++++++++--- gix-protocol/src/fetch/refmap/init.rs | 45 ++++++++-- gix-protocol/src/fetch/response/mod.rs | 60 ++++++++++--- gix-protocol/src/handshake/mod.rs | 69 +++++++++++--- gix-protocol/src/handshake/refs/mod.rs | 83 ++++++++++++++--- gix-protocol/src/ls_refs.rs | 62 +++++++++++-- gix-protocol/tests/protocol/fetch/mod.rs | 71 ++++++++++++--- 11 files changed, 504 insertions(+), 99 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 8860b7e06b6..deca40e17e5 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2306,7 +2306,6 @@ dependencies = [ "gix-utils", "nonempty", "serde", - "thiserror 2.0.18", ] [[package]] diff --git a/gix-protocol/Cargo.toml b/gix-protocol/Cargo.toml index 74a305bd249..02ecd4c269d 100644 --- a/gix-protocol/Cargo.toml +++ b/gix-protocol/Cargo.toml @@ -90,7 +90,6 @@ gix-credentials = { version = "^0.39.0", path = "../gix-credentials", optional = gix-refspec = { version = "^0.44.0", path = "../gix-refspec", optional = true } gix-lock = { version = "^24.0.0", path = "../gix-lock", optional = true } -thiserror = "2.0.18" nonempty = "0.12.0" serde = { version = "1.0.114", optional = true, default-features = false, features = [ "derive", diff --git a/gix-protocol/src/command.rs b/gix-protocol/src/command.rs index 7a3019b451b..50419bb3898 100644 --- a/gix-protocol/src/command.rs +++ b/gix-protocol/src/command.rs @@ -239,14 +239,27 @@ mod with_io { use bstr::BString;

The includes `Realpath` variant wraps gix-path's `Exn` and exposes the inner error via `&**err`. --- Cargo.lock | 2 +- gix-config/Cargo.toml | 2 +- gix-config/src/file/includes/types.rs | 87 +++++++++++++--- gix-config/src/file/init/comfort.rs | 71 +++++++++++--- gix-config/src/file/init/from_env.rs | 81 ++++++++++++--- gix-config/src/file/init/from_paths.rs | 32 +++++- gix-config/src/file/init/types.rs | 62 ++++++++++-- gix-config/src/file/mod.rs | 98 ++++++++++++++++--- gix-config/src/file/section/mod.rs | 38 ++++++- gix-config/src/lookup.rs | 69 +++++++++++-- gix-config/src/parse/mod.rs | 15 ++- gix-config/src/parse/section/header.rs | 32 +++++- gix-config/src/parse/section/mod.rs | 11 ++- .../includes/conditional/gitdir/util.rs | 4 +- 14 files changed, 509 insertions(+), 95 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index deca40e17e5..5a9d33915e6 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1739,6 +1739,7 @@ dependencies = [ "document-features", "gix-config", "gix-config-value", + "gix-error", "gix-features", "gix-glob", "gix-path", @@ -1750,7 +1751,6 @@ dependencies = [ "serde", "serial_test", "smallvec", - "thiserror 2.0.18", "unicode-bom", ] diff --git a/gix-config/Cargo.toml b/gix-config/Cargo.toml index ca6d6c4f35c..481729f20d5 100644 --- a/gix-config/Cargo.toml +++ b/gix-config/Cargo.toml @@ -30,7 +30,6 @@ gix-ref = { version = "^0.66.0", path = "../gix-ref" } gix-glob = { version = "^0.27.0", path = "../gix-glob" } gix-utils = { version = "^0.3.5", path = "../gix-utils", features = ["bstr"] } -thiserror = "2.0.18" unicode-bom = { version = "2.0.3" } bstr = { version = "1.12.0", default-features = false, features = ["std"] } serde = { version = "1.0.114", optional = true, default-features = false, features = ["derive"] } @@ -39,6 +38,7 @@ smallvec = "1.15.1" document-features = { version = "0.2.0", optional = true } [dev-dependencies] +gix-error = { path = "../gix-error", version = "^0.2.5" } criterion = "0.8.2" gix-config = { path = ".", features = ["sha1"] } gix-testtools = { path = "../tests/tools", default-features = false } diff --git a/gix-config/src/file/includes/types.rs b/gix-config/src/file/includes/types.rs index 7aa25c0a873..6f9f5ecadb5 100644 --- a/gix-config/src/file/includes/types.rs +++ b/gix-config/src/file/includes/types.rs @@ -3,27 +3,84 @@ use std::path::PathBuf; use crate::{parse, path::interpolate}; /// The error returned when following includes. -#[derive(Debug, thiserror::Error)] +// TODO(review): hand-written impls preserve the `thiserror` semantics.

Message-bearing variants keep their text verbatim by re-attaching it at the call site with `or_raise`/`and_raise`, so causes stay reachable; transparent variants convert their concrete callees with `Error::from_error`, and callees that already return an erased or `Exn` type propagate with a plain `?`. Two tests that matched removed variants now assert the message instead. This is a partial conversion: 110 `thiserror` derives remain in `gix`, so `gix` still depends on `thiserror` and CI stays red until the sweep finishes. Types whose variants are matched by callers -- notably those backing `IsSpuriousError` impls, and `open::Error` -- are deliberately left as custom enums. The explicit `Error::from_error` mappings are transitional and disappear as the remaining callees are converted. --- gix/src/clone/checkout.rs | 91 +++++++------- gix/src/commit.rs | 67 +++------- gix/src/config/overrides.rs | 29 ++--- gix/src/diff.rs | 51 +++----- gix/src/discover.rs | 20 ++- gix/src/filter.rs | 181 +++++++++++++-------------- gix/src/id.rs | 34 ++--- gix/src/lib.rs | 8 -- gix/src/mailmap.rs | 13 +- gix/src/object/tree/diff/for_each.rs | 24 ++-- gix/src/object/tree/diff/mod.rs | 19 +-- gix/src/object/tree/editor.rs | 66 ++++------ gix/src/pathspec.rs | 37 +++--- gix/src/reference/edits.rs | 32 +++-- gix/src/reference/iter.rs | 37 +++--- gix/src/remote/save.rs | 71 ++++++----- gix/src/repository/attributes.rs | 29 ++--- gix/src/repository/filter.rs | 47 ++++--- gix/src/repository/mailmap.rs | 61 +++++++-- gix/src/repository/object.rs | 31 +++-- gix/src/repository/revision.rs | 9 +- gix/src/revision/spec/parse/mod.rs | 11 +- gix/src/revision/walk.rs | 29 ++--- gix/src/status/index_worktree.rs | 39 ++---- gix/src/status/iter/mod.rs | 59 +++++---- gix/src/status/mod.rs | 27 +--- gix/src/tag.rs | 13 +- gix/src/worktree/mod.rs | 8 +- gix/src/worktree/proxy.rs | 23 ++-- gix/tests/gix/remote/save.rs | 11 +- gix/tests/gix/repository/worktree.rs | 8 +- 31 files changed, 542 insertions(+), 643 deletions(-) diff --git a/gix/src/clone/checkout.rs b/gix/src/clone/checkout.rs index d2296203cac..176ce1509a8 100644 --- a/gix/src/clone/checkout.rs +++ b/gix/src/clone/checkout.rs @@ -2,40 +2,14 @@ use crate::{Repository, clone::PrepareCheckout}; /// pub mod main_worktree { - use std::{path::PathBuf, sync::atomic::AtomicBool}; + use std::sync::atomic::AtomicBool; + + use gix_error::{ErrorExt, ResultExt}; use crate::{Progress, Repository, clone::PrepareCheckout}; /// The error returned by [`PrepareCheckout::main_worktree()`]. - #[derive(Debug, thiserror::Error)] - #[expect(missing_docs)] - pub enum Error { - #[error("Repository at \"{}\" is a bare repository and cannot have a main worktree checkout", git_dir.display())] - BareRepository { git_dir: PathBuf }, - #[error("The object pointed to by HEAD is not a treeish")] - NoHeadTree(#[from] crate::object::peel::to_kind::Error), - #[error("Could not create index from tree at {id}")] - IndexFromTree { - id: gix_hash::ObjectId, - source: gix_index::init::from_tree::Error, - }, - #[error("Couldn't obtain configuration for core.protect*")] - BooleanConfig(#[from] crate::config::boolean::Error), - #[error(transparent)] - WriteIndex(#[from] gix_index::file::write::Error), - #[error(transparent)] - CheckoutOptions(#[from] crate::config::checkout_options::Error), - #[error(transparent)] - IndexCheckout(#[from] gix_worktree_state::checkout::Error), - #[error(transparent)] - Peel(#[from] crate::reference::peel::Error), - #[error("Failed to reopen object database as Arc (only if thread-safety wasn't compiled in)")] - OpenArcOdb(#[from] std::io::Error), - #[error("The HEAD reference could not be located")] - FindHead(#[from] crate::reference::find::existing::Error), - #[error("The HEAD reference could not be located")] - PeelHeadToId(#[from] crate::head::peel::Error), - } + pub type Error = gix_error::Error; /// The progress ids used in [`PrepareCheckout::main_worktree()`]. /// @@ -92,17 +66,35 @@ pub mod main_worktree { .repo .as_ref() .expect("BUG: this method may only be called until it is successful"); - let workdir = repo.workdir().ok_or_else(|| Error::BareRepository { - git_dir: repo.git_dir().to_owned(), + let workdir = repo.workdir().ok_or_else(|| { + gix_error::Error::from_error(gix_error::message!( + "Repository at \"{}\" is a bare repository and cannot have a main worktree checkout", + repo.git_dir().display() + )) })?; let root_tree_id = match &self.ref_name { - Some(reference_val) => Some(repo.find_reference(reference_val)?.peel_to_id()?), - None => repo.head()?.try_peel_to_id()?, + Some(reference_val) => Some( + repo.find_reference(reference_val) + .or_raise(|| gix_error::message("The HEAD reference could not be located"))?

This covers `gix-fs`, `gix-attributes`, `gix-pathspec`, `gix-url`, `gix-path`, `gix-lock`, `gix-shallow` and `gix-prompt`. Several of them have to move together: `gix-pathspec` reads the public `attribute` field off `gix-attributes`' `name::Error`, `gix-url`'s tests propagate `gix_path::realpath::Error`, and `gix-shallow`'s `write::Error` wraps `gix_lock::commit::Error`, so neither of each pair compiles against the other's erased form. Every message is reproduced verbatim. The variants that were `#[error(transparent)]` forward both `Display` and `source()`, those that carried `#[from]` expose the error they hold and keep their conversion, and the ones that wrapped an error without an attribute keep no source at all, matching what the derive generated in each case. Because the error types implement `Error` again, the call sites that bridged through `gix-error` return to a plain `?`, `gix-ref` names `acquire::Error` directly once more, and `gix` converts explicitly at its own boundary where it erases. --- Cargo.lock | 8 - gitoxide-core/src/repository/config.rs | 1 - gix-attributes/Cargo.toml | 1 - gix-attributes/src/name.rs | 25 +- gix-attributes/src/parse.rs | 80 +++-- gix-attributes/tests/attributes/parse.rs | 98 +++--- gix-config/src/file/includes/types.rs | 13 +- .../includes/conditional/gitdir/util.rs | 4 +- gix-credentials/src/protocol/mod.rs | 2 +- gix-credentials/tests/helper/invoke.rs | 7 +- gix-diff/tests/diff/index.rs | 3 +- gix-dir/tests/dir/walk.rs | 11 +- .../tests/discover/upwards/ceiling_dirs.rs | 6 +- gix-discover/tests/discover/upwards/mod.rs | 16 +- gix-fs/Cargo.toml | 1 - gix-fs/src/lib.rs | 3 +- gix-fs/src/stack.rs | 44 ++- gix-index/src/file/write.rs | 4 +- gix-lock/Cargo.toml | 1 - gix-lock/src/acquire.rs | 36 +-- gix-lock/src/lib.rs | 3 +- gix-lock/tests/lock/file.rs | 20 +- gix-lock/tests/lock/marker.rs | 9 +- gix-path/Cargo.toml | 1 - gix-path/src/realpath.rs | 74 +++-- gix-path/src/relative_path.rs | 66 ++-- gix-path/tests/path/realpath.rs | 61 ++-- gix-path/tests/path/relative_path.rs | 302 ++++++------------ gix-pathspec/Cargo.toml | 1 - gix-pathspec/fuzz/fuzz_targets/parse.rs | 2 +- gix-pathspec/src/defaults.rs | 42 ++- gix-pathspec/src/lib.rs | 38 ++- gix-pathspec/src/parse.rs | 112 ++++--- gix-pathspec/src/pattern.rs | 16 +- gix-pathspec/tests/defaults.rs | 10 +- gix-pathspec/tests/normalize/mod.rs | 12 +- gix-pathspec/tests/parse/invalid.rs | 58 +--- gix-pathspec/tests/parse/valid.rs | 6 +- gix-pathspec/tests/search/mod.rs | 80 ++--- gix-prompt/Cargo.toml | 2 - gix-prompt/examples/askpass.rs | 2 +- gix-prompt/examples/use-askpass.rs | 3 +- gix-prompt/src/lib.rs | 8 +- gix-prompt/src/types.rs | 54 +++- gix-prompt/src/unix.rs | 44 +-- gix-protocol/src/fetch/error.rs | 10 +- gix-ref/src/store/file/overlay_iter.rs | 5 +- gix-ref/src/store/file/packed.rs | 7 +- gix-ref/src/store/file/transaction/prepare.rs | 10 +- gix-shallow/Cargo.toml | 1 - gix-shallow/src/lib.rs | 135 +++++--- gix-submodule/src/is_active_platform.rs | 9 +- gix-url/Cargo.toml | 1 - gix-url/src/expand_path.rs | 42 ++- gix-url/src/parse.rs | 1 + gix-url/src/simple_url.rs | 12 +- gix-url/tests/url/access.rs | 17 +- gix-url/tests/url/expand_path.rs | 12 +- gix/src/pathspec.rs | 8 +- gix/src/reference/iter.rs | 8 +- .../connection/fetch/update_refs/tests.rs | 3 +- gix/src/revision/walk.rs | 2 +- gix/src/status/index_worktree.rs | 3 +- gix/tests/gix/clone.rs | 7 +- gix/tests/gix/remote/fetch.rs | 6 +- gix/tests/gix/repository/shallow.rs | 7 +- gix/tests/gix/repository/worktree.rs | 33 +- gix/tests/gix/submodule.rs | 3 +- src/porcelain/options.rs | 1 - src/shared.rs | 10 +- tests/it/src/args.rs | 1 - tests/tools/src/lib.rs | 3 +- 72 files changed, 860 insertions(+), 887 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index ab7b81a10a6..90a51d46ab9 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1648,7 +1648,6 @@ dependencies = [ "bstr", "criterion", "document-features", - "gix-error", "gix-features", "gix-fs", "gix-glob", @@ -1927,7 +1926,6 @@ version = "0.22.0" dependencies = [ "bstr", "crossbeam-channel", - "gix-error", "gix-features", "gix-path", "gix-utils", @@ -2052,7 +2050,6 @@ version = "0.0.0" name = "gix-lock" version = "24.0.0" dependencies = [ - "gix-error", "gix-tempfile", "gix-utils", "tempfile", @@ -2239,7 +2236,6 @@ name = "gix-path" version = "0.12.3" dependencies = [ "bstr", - "gix-error", "gix-testtools", "gix-trace", "gix-validate", @@ -2256,7 +2252,6 @@ dependencies = [ "bstr", "gix-attributes", "gix-config-value", - "gix-error", "gix-glob", "gix-path", "gix-testtools", @@ -2270,7 +2265,6 @@ dependencies = [ "expectrl", "gix-command", "gix-config-value", - "gix-error", "gix-testtools", "parking_lot", "rustix", @@ -2420,7 +2414,6 @@ name = "gix-shallow" version = "0.13.0" dependencies = [ "bstr", - "gix-error", "gix-hash", "gix-lock", "nonempty", @@ -2586,7 +2579,6 @@ dependencies = [ "assert_matches", "bstr", "document-features", - "gix-error", "gix-path", "gix-testtools", "gix-utils", diff --git a/gitoxide-core/src/repository/config.rs b/gitoxide-core/src/repository/config.rs index e270c594315..eab8866273a 100644 --- a/gitoxide-core/src/repository/config.rs +++ b/gitoxide-core/src/repository/config.rs @@ -105,7 +105,6 @@ pub fn fmt( let lock = in_place .then(|| { gix::lock::File::acquire_to_update_resource(&source, gix::lock::acquire::Fail::Immediately, None) - .map_err(gix::Error::from) .with_context(|| format!("Could not lock configuration file at '{}'", source.display())) }) .transpose()?;

Erased in `repository/mod.rs`: `new_commit`, `new_commit_as`, `branch_remote_ref_name`, `branch_remote_tracking_ref_name`, `upstream_branch_and_remote_name_for_tracking_branch`, `pathspec_defaults_ignore_case`, `index_or_load_from_head`. Erased in `reference/errors.rs`: `peel::to_kind`, `follow::to_object`, `head_id`, `head_commit`, `head_tree`, `find`. Four types that were targeted stay concrete because erasing them would embed a second `gix_error::Error` in a parent enum and collide on `From` (E0119): `diff_resource_cache`, `index_from_tree`, `index_or_load_from_head_or_empty` (through the `status`/`worktree_stream` chains) and `head_tree_id` (through `status::is_dirty`). Each carries a `TODO(review)` naming the collision. Call sites that bridged through these types go to a plain `?` where the callee is now erased, and to `.map_err(gix_error::Error::from_error)` where it stays concrete. Every message on an erased variant is preserved verbatim at its construction site via `or_raise`/`message!`. `head_tree_id_or_empty` recovered its unborn-HEAD case by matching the nested error structurally; since `head_commit`'s error is now erased, it intercepts `peel_to_commit`'s still-concrete error and recovers `Unborn` via `downcast_any_ref`, which works regardless of the `tree-error` feature. --- gix/src/reference/errors.rs | 59 +++--------------- gix/src/reference/mod.rs | 16 +++-- gix/src/repository/config/branch.rs | 64 ++++++++++++------- gix/src/repository/index.rs | 6 +- gix/src/repository/mod.rs | 95 +++++++---------------------- gix/src/repository/object.rs | 16 +++-- gix/src/repository/pathspec.rs | 8 ++- gix/src/repository/reference.rs | 51 +++++++++++----- gix/src/submodule/errors.rs | 4 ++ gix/src/worktree/mod.rs | 12 +++- 10 files changed, 153 insertions(+), 178 deletions(-) diff --git a/gix/src/reference/errors.rs b/gix/src/reference/errors.rs index eb8d7a4cede..6355774f1fc 100644 --- a/gix/src/reference/errors.rs +++ b/gix/src/reference/errors.rs @@ -38,18 +38,7 @@ pub mod peel { /// pub mod to_kind { /// The error returned by [`Reference::peel_to_kind(…)`](crate::Reference::peel_to_kind()). - #[derive(Debug, thiserror::Error)] - #[expect(missing_docs)] - pub enum Error { - #[error(transparent)] - FollowToObject(#[from] gix_ref::peel::to_object::Error), - #[error(transparent)] - PackedRefsOpen(#[from] gix_ref::packed::buffer::open::Error), - #[error(transparent)] - FindObject(#[from] crate::object::find::existing::Error), - #[error(transparent)] - PeelObject(#[from] crate::object::peel::to_kind::Error), - } + pub type Error = gix_error::Error;

Of the ten messages these types carried, five are reproduced verbatim at the sites that produce them. The other five had no producer: `pack::explode`'s `Io` and `OdbWrite` could only be reached through `From` conversions that no code path took, because `gix_object::write::Error` boxes those errors long before they arrive, and `input_iteration`'s three belong to a type nothing references. `gix` is now the only crate in the workspace that still depends on `thiserror`. --- Cargo.lock | 1 - gitoxide-core/Cargo.toml | 1 - gitoxide-core/src/pack/create.rs | 11 +--- gitoxide-core/src/pack/explode.rs | 68 +++++++++------------- gitoxide-core/src/repository/credential.rs | 30 ++++------ 5 files changed, 39 insertions(+), 72 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 86ccb6de2ba..5555ac6ca99 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1523,7 +1523,6 @@ dependencies = [ "smallvec", "sysinfo", "tempfile", - "thiserror 2.0.18", "tracing", "tracing-forest 0.2.0", "tracing-subscriber", diff --git a/gitoxide-core/Cargo.toml b/gitoxide-core/Cargo.toml index f367ceffd39..fafc43b2812 100644 --- a/gitoxide-core/Cargo.toml +++ b/gitoxide-core/Cargo.toml @@ -58,7 +58,6 @@ gix-fsck = { version = "^0.24.0", path = "../gix-fsck" } gix-error-for-configuration-only = { package = "gix-error", version = "^0.2.5", path = "../gix-error", features = ["anyhow"] } serde = { version = "1.0.114", optional = true, default-features = false, features = ["derive"] } anyhow = "1.0.102" -thiserror = "2.0.18" bytesize = "2.3.1" tempfile = "3.26.0" unicode-width = "0.2.2" diff --git a/gitoxide-core/src/pack/create.rs b/gitoxide-core/src/pack/create.rs index 631db5376dc..4e472790585 100644 --- a/gitoxide-core/src/pack/create.rs +++ b/gitoxide-core/src/pack/create.rs @@ -360,14 +360,5 @@ struct Statistics { } pub mod input_iteration { - use gix::{hash, traverse}; - #[derive(Debug, thiserror::Error)] - pub enum Error { - #[error("input objects couldn't be iterated completely")] - Iteration(#[from] traverse::commit::simple::Error), - #[error("An error occurred while reading hashes from standard input")] - InputLinesIo(#[from] std::io::Error), - #[error("Could not decode hex hash provided on standard input")] - HashDecode(#[from] hash::decode::Error), - } + pub type Error = gix::Error; } diff --git a/gitoxide-core/src/pack/explode.rs b/gitoxide-core/src/pack/explode.rs index 878f000c3b5..31e4c3f4f24 100644 --- a/gitoxide-core/src/pack/explode.rs +++ b/gitoxide-core/src/pack/explode.rs @@ -8,8 +8,9 @@ use std::{ use anyhow::{Result, anyhow}; use gix::{ NestedProgress, + error::{ErrorExt, OptionExt, ResultExt}, hash::ObjectId, - object, objs, odb, + object, odb, odb::{loose, pack}, prelude::Write, }; @@ -64,32 +65,6 @@ impl From for pack::index::traverse::SafetyCheck { } } -#[derive(Debug, thiserror::Error)] -enum Error { - #[error("An IO error occurred while writing an object")] - Io(#[from] std::io::Error), - #[error("An object could not be written to the database")] - OdbWrite(#[from] loose::write::Error), - #[error("Failed to write {kind} object {id}")] - Write { - source: Box, - kind: object::Kind, - id: ObjectId, - }, - #[error("Object didn't verify after right after writing it")] - Verify(#[from] objs::data::verify::Error), - #[error("{kind} object wasn't re-encoded without change")] - ObjectEncodeMismatch { - #[source] - source: gix::hash::verify::Error, - kind: object::Kind, - }, - #[error("The recently written file for loose object {id} could not be found")] - WrittenFileMissing { id: ObjectId }, - #[error("The recently written file for loose object {id} cold not be read")] - WrittenFileCorrupt { source: loose::find::Error, id: ObjectId }, -} - #[expect( clippy::large_enum_variant, reason = "will be removed once `gix-error` is used consistently" @@ -242,11 +217,12 @@ pub fn pack_or_pack_index( .flatten(); let mut read_buf = Vec::new(); move |object_kind, buf, index_entry, progress| { - let written_id = out.write_buf(object_kind, buf).map_err(|err| Error::Write { - source: err, - kind: object_kind, - id: index_entry.oid, - })?; + let written_id = out + .write_buf(object_kind, buf) + .map_err(std::io::Error::other) + .or_raise(|| { + gix::error::message!("Failed to write {kind} object {id}", kind = object_kind, id = index_entry.oid) + })?; if let Err(err) = written_id.verify(&index_entry.oid) { if let object::Kind::Tree = object_kind { progress.info(format!( @@ -254,21 +230,31 @@ pub fn pack_or_pack_index( index_entry.oid, written_id )); } else { - return Err(Error::ObjectEncodeMismatch { - source: err, - kind: object_kind, - }); + return Err(err + .and_raise(gix::error::message!( + "{kind} object wasn't re-encoded without change", + kind = object_kind + )) + .into_error()); } } if let Some(verifier) = loose_odb.as_ref() { let obj = verifier .try_find(&written_id, &mut read_buf) - .map_err(|err| Error::WrittenFileCorrupt { - source: err, - id: written_id, + .or_raise(|| { + gix::error::message!( + "The recently written file for loose object {id} cold not be read", + id = written_id + ) })?

Four more were targeted but stay concrete. Three because a parent enum already embeds an erased error and a second one would collide on `From` (E0119): `exclude_stack` through `dirwalk`, `protocol::allow` through `remote::connect` and `commit_signature` through `clone::fetch`. `attribute_stack` is blocked the same way, through `checkout_options`. `stat_options` is a different case: nothing embeds it, but `checkout_options()` maps its two variants across by hand, which an erased type cannot support. Each carries a `TODO(review)` saying which of the two it is. The top-level `config::Error` gained a note as well: erasing `abbrev` spent the one slot it has, so no other `#[from]` member of that enum can be erased without colliding. `key::Error` is deliberately untouched. It is generic over its source and two const parameters, and fourteen aliases are built on it, so it has no erased form. Every message on an erased type is reproduced verbatim where it is produced. That includes the context `transport::Error` used to add when an `http::Error` crossed into it, which the erasure turned into an identity conversion; it is restored at all twelve crossings. `diff_algorithm()` could no longer match the `Unimplemented` variant to decide whether a lenient configuration should fall back, so it re-derives the same condition from the input instead, and a test now covers both outcomes. --- gix/src/config/cache/access.rs | 52 ++++-- gix/src/config/mod.rs | 154 ++++++------------ gix/src/config/tree/sections/core.rs | 38 ++--- gix/src/config/tree/sections/diff.rs | 9 +- gix/src/diff.rs | 8 +- gix/src/repository/config/transport.rs | 83 ++++++---- .../generated-archives/make_config_repos.tar | Bin 1421824 -> 1467392 bytes .../make_config_repos_sha256.tar | Bin 1421824 -> 1467392 bytes gix/tests/fixtures/make_config_repos.sh | 5 + .../gix/repository/config/diff_algorithm.rs | 25 +++ gix/tests/gix/repository/config/mod.rs | 2 + 11 files changed, 197 insertions(+), 179 deletions(-) create mode 100644 gix/tests/gix/repository/config/diff_algorithm.rs diff --git a/gix/src/config/cache/access.rs b/gix/src/config/cache/access.rs index df1098596e9..09f16498f20 100644 --- a/gix/src/config/cache/access.rs +++ b/gix/src/config/cache/access.rs @@ -2,6 +2,7 @@ use std::{path::PathBuf, time::Duration}; use gix_config::file::Metadata; +use gix_error::ResultExt; use gix_lock::acquire::Fail; use crate::{ @@ -19,15 +20,22 @@ use crate::{ impl Cache { #[cfg(feature = "blob-diff")] pub(crate) fn diff_algorithm(&self) -> Result { - use crate::config::{cache::util::ApplyLeniencyDefault, diff::algorithm::Error, tree::Diff}; + use crate::config::{cache::util::ApplyLeniencyDefault, tree::Diff}; self.diff_algorithm .get_or_try_init(|| { let name = self.resolved.string(Diff::ALGORITHM).unwrap_or_else(|| "myers".into()); + // `try_into_algorithm()`'s error is erased, so we can no longer match its + // `Unimplemented` variant here; re-derive the same condition from `name` instead, + // matching the one place `try_into_algorithm()` returns that particular error. + let is_unimplemented = name.eq_ignore_ascii_case(b"patience"); config::tree::Diff::ALGORITHM .try_into_algorithm(name) - .or_else(|err| match err { - Error::Unimplemented { .. } if self.lenient_config => Ok(gix_diff::blob::Algorithm::Histogram), - err => Err(err), + .or_else(|err| { + if is_unimplemented && self.lenient_config { + Ok(gix_diff::blob::Algorithm::Histogram) + } else { + Err(err) + } }) .with_lenient_default(self.lenient_config) }) @@ -64,11 +72,14 @@ impl Cache { driver.is_binary = config::tree::Diff::DRIVER_BINARY .try_into_binary(binary) .with_leniency(self.lenient_config) - .map_err(|err| config::diff::drivers::Error { - name: driver.name.clone(), - attribute: "binary", - source: Box::new(err), - })?; + .or_raise(|| { + gix_error::message!( + "Failed to parse value of 'diff.{name}.{attribute}'", + name = driver.name, + attribute = "binary" + ) + }) + .map_err(gix_error::Error::from)?; } if let Some(command) = section.value(config::tree::Diff::DRIVER_COMMAND.name) { driver.command = command.into(); @@ -77,20 +88,27 @@ impl Cache { driver.binary_to_text_command = textconv.into(); } if let Some(algorithm) = section.value("algorithm") { + // See the comment in `diff_algorithm()` above: re-derive the `Unimplemented` + // condition from `algorithm` since `try_into_algorithm()`'s error is now erased. + let is_unimplemented = algorithm.eq_ignore_ascii_case(b"patience"); driver.algorithm = config::tree::Diff::DRIVER_ALGORITHM .try_into_algorithm(algorithm) - .or_else(|err| match err { - config::diff::algorithm::Error::Unimplemented { .. } if self.lenient_config => { + .or_else(|err| { + if is_unimplemented && self.lenient_config { Ok(gix_diff::blob::Algorithm::Histogram) + } else { + Err(err) } - err => Err(err), }) .with_lenient_default(self.lenient_config) - .map_err(|err| config::diff::drivers::Error { - name: driver.name.clone(), - attribute: "algorithm", - source: Box::new(err), - })?

Four others were targeted and stay concrete. Erasing `find` or `commit` would give a parent enum a second `From` and collide: `update::Error` already embeds the erased `reference::find::Error`, and `submodule::head_id::Error` the erased `reference::head_commit::Error`. `try_into` is destructured by two callers that read its fields, in `object::commit` and in the revision-spec delegate. `blob::diff::lines::Error` is generic over the caller's own error and hands it back through `ProcessHunk`, which a type alias cannot express. Each carries a `TODO(review)`. Every message on an erased type is reproduced verbatim where it is produced. One test changes, and it is worth saying why. `peel::to_kind::Error::NotFound` carried the offending object id and both kinds as fields, and a revision-spec test asserts on that frame's `Debug` inside the error tree. The text it prints is unchanged — the assertion covering the printed form passes untouched — but the typed frame is gone, so the tree now shows the same sentence as a `Message`. Keeping it typed would mean holding a private concrete payload behind the erased type; the snapshot follows the erasure instead, matching what the migration notes prescribe for formatted variants. --- gix/src/filter.rs | 14 ++---- gix/src/object/blob.rs | 4 ++ gix/src/object/commit.rs | 5 ++ gix/src/object/errors.rs | 31 ++++-------- gix/src/object/mod.rs | 38 ++++++++++----- gix/src/object/peel.rs | 36 ++++---------- gix/src/object/tree/editor.rs | 6 +-- gix/src/reference/mod.rs | 1 - gix/src/repository/merge.rs | 3 +- gix/src/repository/object.rs | 48 +++++++++++-------- .../gix/revision/spec/from_bytes/ambiguous.rs | 2 +- 11 files changed, 88 insertions(+), 100 deletions(-) diff --git a/gix/src/filter.rs b/gix/src/filter.rs index 2921230df50..2abf6018224 100644 --- a/gix/src/filter.rs +++ b/gix/src/filter.rs @@ -226,9 +226,7 @@ impl Pipeline<'_> { path.display() ))) })?; - let id = repo - .write_blob(gix_path::into_bstr(target).as_ref()) - .map_err(gix_error::Error::from_error)?; + let id = repo.write_blob(gix_path::into_bstr(target).as_ref())?; (id, gix_object::tree::EntryKind::Link) } else if md.is_file() { use gix_filter::pipeline::convert::ToGitOutcome; @@ -241,13 +239,9 @@ impl Pipeline<'_> { })?; let file_for_git = self.convert_to_git(file, rela_path_as_path.as_ref(), index)?; let id = match file_for_git { - ToGitOutcome::Unchanged(mut file) => repo - .write_blob_stream(&mut file) - .map_err(gix_error::Error::from_error)?, - ToGitOutcome::Buffer(buf) => repo.write_blob(buf).map_err(gix_error::Error::from_error)?, - ToGitOutcome::Process(mut read) => repo - .write_blob_stream(&mut read) - .map_err(gix_error::Error::from_error)?, + ToGitOutcome::Unchanged(mut file) => repo.write_blob_stream(&mut file)?, + ToGitOutcome::Buffer(buf) => repo.write_blob(buf)?, + ToGitOutcome::Process(mut read) => repo.write_blob_stream(&mut read)?, }; let kind = if gix_fs::is_executable(&md) { diff --git a/gix/src/object/blob.rs b/gix/src/object/blob.rs index 17860f16fdc..35d9fb51104 100644 --- a/gix/src/object/blob.rs +++ b/gix/src/object/blob.rs @@ -25,6 +25,10 @@ pub mod diff { use crate::bstr::BStr; /// The error returned by [Platform::lines()](super::Platform::lines()). + // TODO(review): kept concrete.

All of their variants were transparent, so no message moves; the one message in the file, on the case-sensitivity lookup in `pathspec()`, is reproduced verbatim and still built only when that lookup fails. `worktree::open_index` stays concrete. It is embedded by two enums that already embed an erased error, so erasing it would give each of them a second `From` and collide: `repository::index_or_load_from_head_or_empty::Error` through `object::peel::to_kind::Error`, and `status::is_dirty::Error` through `status::into_iter::Error`. A `TODO(review)` names both. That second one is worth noting for whoever continues this: `is_dirty::Error` now pins three types concrete on its own — `reference::head_tree_id`, `status::tree_index` and `worktree::open_index` — because one of its five members is erased and only one can be. --- gix/src/worktree/mod.rs | 78 ++++++++++++++++------------------------- 1 file changed, 30 insertions(+), 48 deletions(-) diff --git a/gix/src/worktree/mod.rs b/gix/src/worktree/mod.rs index 686151d9669..ea1c0d9b70a 100644 --- a/gix/src/worktree/mod.rs +++ b/gix/src/worktree/mod.rs @@ -119,6 +119,13 @@ pub mod proxy; #[cfg(feature = "index")] pub mod open_index { /// The error returned by [`Worktree::open_index()`][crate::Worktree::open_index()]. + // TODO(review): kept concrete due to two separate E0119 collisions on external parents that embed + // this type via `#[from]`: `repository::index_or_load_from_head_or_empty::Error` + // (`gix/src/repository/mod.rs`, via `OpenIndex`) already embeds the erased + // `object::peel::to_kind::Error` via `PeelToTree`; `status::is_dirty::Error` + // (`gix/src/status/mod.rs`, via `OpenWorktreeIndex`) already embeds the erased + // `status::into_iter::Error` via `CreateStatusIterator`.

All twelve messages the first two carried are reproduced verbatim where they are produced. `object::find` is here rather than in its own batch because erasing `update::Error` dissolved the reason it had been kept concrete: the collision was with `update::Error`'s variants, and those no longer exist. Its `TODO(review)` said otherwise and has been removed. Five types under `remote/` stay concrete, and for two different reasons. `remote::init` and `remote::name` would each give a parent enum a second `From`: `clone::fetch::Error` and `remote::save::AsError` respectively. `ref_map`, `fetch` and `fetch::prepare` are blocked more firmly — each implements `gix_protocol::transport::IsSpuriousError`, which would become a foreign trait on a foreign type once the error is an alias, and that trait is how a transient network failure is told apart from a permanent one. Erasing them would cost retry behaviour, not just a trait impl. Callers also match their variants in `env.rs` and `clone::fetch`. `object::find` wrapped a boxed error, and `thiserror`'s derive handled that for its two producers. `gix_error::Error::from_error` does not, so `try_find_header` and `try_find_object` now bridge through `io::Error::other`, as this crate already does elsewhere. --- gix/src/object/errors.rs | 9 +-- gix/src/remote/connection/fetch/error.rs | 13 ++++ gix/src/remote/connection/fetch/mod.rs | 13 ++++ .../connection/fetch/update_refs/mod.rs | 67 ++++++++++++++++--- .../connection/fetch/update_refs/update.rs | 31 +-------- gix/src/remote/connection/ref_map.rs | 10 +++ gix/src/remote/errors.rs | 23 +------ gix/src/remote/init.rs | 5 ++ gix/src/remote/name.rs | 7 ++ gix/src/repository/config/branch.rs | 2 +- gix/src/repository/object.rs | 10 ++- gix/src/repository/remote.rs | 42 ++++++------ 12 files changed, 140 insertions(+), 92 deletions(-) diff --git a/gix/src/object/errors.rs b/gix/src/object/errors.rs index b5ce31a3588..35036ccf587 100644 --- a/gix/src/object/errors.rs +++ b/gix/src/object/errors.rs @@ -6,15 +6,8 @@ pub mod conversion { /// pub mod find { - // TODO(review): kept concrete.

Three of them were only ever mentioned as the reason *other* types were blocked, and nobody had tried them: `status::is_dirty`, `repository::worktree_stream` and `config::checkout_options`. None had a parent embedding them, so all three erase. Doing so freed three more, which are erased here too: `reference::head_tree_id`, `config::command_context` and `config::stat_options`. `checkout_options()` no longer needs to re-map `stat_options`' two variants by hand, since both sides are the same type now. Four types stay concrete, and their notes were wrong. `index_from_tree` and `attribute_stack` blamed hubs that this commit removes; `open_index` named one real blocker and one that no longer exists; `tree_index` had no note at all despite being blocked by `status::iter::Error`. All four now name blockers that were confirmed by compiling with the type erased and reading the error. Only `worktree_stream::Error::NotATree` carried a message; it is reproduced where it is produced. Nine call sites that wrapped these errors no longer need to and were collapsed to `?`. --- gix/src/clone/checkout.rs | 4 +- gix/src/commit.rs | 2 +- gix/src/config/cache/access.rs | 44 ++++++++++++---------- gix/src/config/mod.rs | 63 +++++--------------------------- gix/src/diff.rs | 5 +-- gix/src/filter.rs | 5 +-- gix/src/reference/errors.rs | 12 +----- gix/src/repository/config/mod.rs | 9 +++-- gix/src/repository/merge.rs | 7 +--- gix/src/repository/mod.rs | 30 ++++----------- gix/src/repository/reference.rs | 6 +-- gix/src/repository/worktree.rs | 17 +++++---- gix/src/status/index_worktree.rs | 2 +- gix/src/status/mod.rs | 23 +++--------- gix/src/status/tree_index.rs | 6 +++ gix/src/worktree/mod.rs | 9 ++--- 16 files changed, 82 insertions(+), 162 deletions(-) diff --git a/gix/src/clone/checkout.rs b/gix/src/clone/checkout.rs index 176ce1509a8..8da32ba09c2 100644 --- a/gix/src/clone/checkout.rs +++ b/gix/src/clone/checkout.rs @@ -114,9 +114,7 @@ pub mod main_worktree { })?; let mut index = gix_index::File::from_state(index, repo.index_path()); - let mut opts = repo - .checkout_options(gix_worktree::stack::state::attributes::Source::IdMapping) - .map_err(gix_error::Error::from_error)?; + let mut opts = repo.checkout_options(gix_worktree::stack::state::attributes::Source::IdMapping)?; opts.destination_is_initially_empty = true; let mut files = progress.add_child_with_id("checkout".to_string(), ProgressId::CheckoutFiles.into()); diff --git a/gix/src/commit.rs b/gix/src/commit.rs index 121b2d92f61..3fc7019dcd7 100644 --- a/gix/src/commit.rs +++ b/gix/src/commit.rs @@ -51,7 +51,7 @@ pub mod describe { .shorten() .or_raise(|| gix_error::message("Could not produce an unambiguous shortened id for formatting."))?; let mut dirty_suffix = dirty_suffix.into(); - if dirty_suffix.is_some() && !self.id.repo.is_dirty().map_err(gix_error::Error::from_error)?

Each note names one of four structural blockers found during the conversion: callers matching variants or reading fields, a parent enum whose single `From` slot is already spent (E0119), a type parameter that a `pub type` alias cannot carry, or a local implementation of a foreign trait (E0117). Blockers inside `gix/src` are cited by symbol name rather than by line number, so those references survive later edits to the files they point into. Citations into `gix/tests` keep their line numbers: they point at caller match sites that have no unique symbol to name, in a tree this campaign does not modify. --- gix/src/clone/fetch/mod.rs | 2 ++ gix/src/clone/mod.rs | 3 +++ gix/src/config/mod.rs | 24 +++++++++++++++++++ gix/src/config/snapshot/credential_helpers.rs | 10 ++++++++ gix/src/config/tree/mod.rs | 14 +++++++++++ gix/src/create.rs | 3 +++ gix/src/dirwalk/iter.rs | 5 ++++ gix/src/dirwalk/mod.rs | 7 ++++++ gix/src/env.rs | 12 ++++++++++ gix/src/head/peel.rs | 20 ++++++++++++++++ gix/src/init.rs | 3 +++ gix/src/open/mod.rs | 8 +++++++ gix/src/reference/errors.rs | 20 ++++++++++++++++ gix/src/remote/connect.rs | 11 +++++++++ gix/src/remote/connection/fetch/mod.rs | 12 ++++++---- gix/src/remote/connection/ref_map.rs | 7 +++--- gix/src/remote/errors.rs | 8 +++++++ gix/src/remote/save.rs | 8 ++++--- gix/src/repository/mod.rs | 4 ++++ gix/src/status/index_worktree.rs | 8 +++++++ gix/src/status/iter/mod.rs | 6 +++++ gix/src/status/mod.rs | 8 +++++++ gix/src/submodule/errors.rs | 14 +++++++++++ gix/src/submodule/mod.rs | 5 ++++ 24 files changed, 211 insertions(+), 11 deletions(-) diff --git a/gix/src/clone/fetch/mod.rs b/gix/src/clone/fetch/mod.rs index 70799c3b39c..b23b49d20c1 100644 --- a/gix/src/clone/fetch/mod.rs +++ b/gix/src/clone/fetch/mod.rs @@ -4,6 +4,8 @@ use crate::{ }; use gix_ref::Category; +// TODO(review): kept concrete.

Its two message variants (`MissingWorkDir`, `ListWorktrees`) are re-raised via `or_raise`/ `ok_or_raise` at their construction sites in `gix/src/repository/dirwalk.rs`. - `dirwalk::iter::Error` (`gix/src/dirwalk/iter.rs`) — cfg-split on the `parallel` feature; repaired in both the threaded producer path and the serial fallback path, including its `SpawnThread` message. - `config::exclude_stack::Error` (`gix/src/config/mod.rs`) — only possible now that `dirwalk::Error` no longer collides with it via two `From` impls (the E0119 the surviving note used to cite). Both its messages (`Io`, `ExcludesFilePathInterpolation`) are re-raised at their construction site in `Cache::assemble_exclude_globals()` (`gix/src/config/cache/access.rs`). Beyond the audited call sites, this also fixes two double-wraps that the erasure of `exclude_stack::Error` would otherwise silently introduce — a callee returning `gix_error::Error` wrapped again via `.map_err(gix_error::Error::from_error)`, which compiles but nests erased-in-erased: - `Repository::excludes()`'s call into `assemble_exclude_globals()` (`gix/src/repository/attributes.rs`), collapsed to a plain `?`. - `Worktree::excludes()`'s call into `Repository::excludes()` (`gix/src/worktree/mod.rs`), where the trailing `.map_err(...)` is now dropped entirely since both sides are `gix_error::Error`. Deletes the `TODO(review)` note on each of the three erased types. --- gix/src/config/cache/access.rs | 12 ++++++++---- gix/src/config/mod.rs | 22 +--------------------- gix/src/dirwalk/iter.rs | 28 +++++++--------------------- gix/src/dirwalk/mod.rs | 28 ++-------------------------- gix/src/repository/attributes.rs | 7 +++---- gix/src/repository/dirwalk.rs | 20 ++++++++++++++------ gix/src/worktree/mod.rs | 12 +++++------- 7 files changed, 40 insertions(+), 89 deletions(-) diff --git a/gix/src/config/cache/access.rs b/gix/src/config/cache/access.rs index d1be88cd4be..0e438945253 100644 --- a/gix/src/config/cache/access.rs +++ b/gix/src/config/cache/access.rs @@ -410,14 +410,18 @@ impl Cache { source: gix_worktree::stack::state::ignore::Source, buf: &mut Vec, ) -> Result { - let excludes_file = match self.excludes_file()? { + let excludes_file = match self + .excludes_file() + .or_raise(|| gix_error::message("The value for `core.excludesFile` could not be read from configuration"))? + { Some(user_path) => Some(user_path), - None => self.xdg_config_path("ignore")?, + None => self.xdg_config_path("ignore").map_err(gix_error::Error::from_error)?, }; - let parse_ignore = self.ignore_pattern_parser()?; + let parse_ignore = self.ignore_pattern_parser().map_err(gix_error::Error::from_error)?; Ok(gix_worktree::stack::state::Ignore::new( overrides.unwrap_or_default(), - gix_ignore::Search::from_git_dir(git_dir, excludes_file, buf, parse_ignore)?, + gix_ignore::Search::from_git_dir(git_dir, excludes_file, buf, parse_ignore) + .or_raise(|| gix_error::message("Could not read repository exclude"))?, None, source, parse_ignore, diff --git a/gix/src/config/mod.rs b/gix/src/config/mod.rs index 4ed1551ca0f..9c2015016ac 100644 --- a/gix/src/config/mod.rs +++ b/gix/src/config/mod.rs @@ -203,28 +203,8 @@ pub mod command_context { /// pub mod exclude_stack { - use crate::config; - use std::path::PathBuf; - - // TODO(review): kept concrete due to an E0119 collision. `gix::dirwalk::Error` - // (`gix/src/dirwalk/mod.rs`) embeds both this type, via - // `Excludes(#[from] config::exclude_stack::Error)`, and the already-erased - // `crate::pathspec::init::Error`, via `Pathspec(#[from] ...)`.

charset=UTF-8 Content-Transfer-Encoding: 8bit Erase two error types proven safe to collapse to `gix_error::Error`, both in `gix/src/head/peel.rs`: - `head::peel::Error` — its two variants were `#[error(transparent)]` (`FindExistingObject`, `PeelReference`), so no message needed re-raising; every internal call site (`id.header()`, `id.object()`, `peel_tags_to_end()`, `nr.peel_to_id()`) is now a plain `.map_err(gix_error::Error::from_error)`, and the one manual construction in `peel_to_object()` (`Error::FindExistingObject(err)`, wrapped inside the still-concrete `to_object::Error::Peel`) becomes `gix_error::Error::from_error(err)`. - `head::peel::into_id::Error` — its `Unborn { name }` message is re-raised via `gix_error::Error::from_error(gix_error::message!("Branch '{name}' does not have any commits"))` at its construction site in `into_peeled_id()`. Beyond the audited call sites, this also fixes two double-wraps that these erasures would otherwise silently introduce — a callee returning `gix_error::Error` wrapped again via `.map_err(gix_error::Error::from_error)`: - `Repository::head_id()` (`gix/src/repository/reference.rs`): its call into `Head::into_peeled_id()` had a trailing `.map_err(...)` that is now dropped, since both sides are `gix_error::Error`. - `Repository::modules()` (`gix/src/repository/submodule.rs`): its call into `Head::try_peel_to_id()` is now a plain `?`, for the same reason. Also fixes a stale note: `reference::peel::Error`'s `TODO(review)` (`gix/src/reference/errors.rs`) cited `head::peel::Error::PeelReference` as a collision-free parent; that variant no longer exists once `head::peel::Error` is a type alias, so the now-inaccurate clause is dropped. The note's actual justification (callers match `reference::peel::Error::ToId(...)` directly) is unaffected and unchanged.

Its `Validate` variant needs no wrapper: `validate::Error` is erased in this same commit, so those call sites remain a plain `?`. Its two message variants (`SubSectionRequired`, `SubSectionForbidden`) are re-raised via `gix_error::Error::from_error(gix_error::message(...))` at their construction sites in the same file. - `config::tree::key::validate::Error` (`gix/src/config/tree/mod.rs`) — its sole field was `Box`, which `gix_error::Error::from_error()` can't accept directly (the std blanket impl needs `Sized`); bridged via `std::io::Error::other(err)` at the one call site in `Any::::validate()` (`gix/src/config/tree/keys.rs`), matching the idiom already shipped in `gix/src/pathspec.rs`. - `config::tree::key::validate_assignment::Error` (same file) — its `Validate` message is re-raised via `.or_raise(...)`, and its `Name` message via `gix_error::Error::from_error(gix_error::message!("{message}"))`, at both call sites in `gix/src/config/tree/traits.rs` (`validated_assignment()`/`validated_assignment_with_subsection()`). - `config::snapshot::credential_helpers::Error` (`gix/src/config/snapshot/credential_helpers.rs`) — its `InvalidUseHttpPath` and `CoreAskpass` messages are re-raised via `or_raise`/`message!`, and its transparent `BooleanConfig` variant (plus the untouched `protect_protocol` and two `HELPER_STDERR`/`TERMINAL_PROMPT` sites) become plain `.map_err(gix_error::Error::from_error)`. - `status::index_worktree::submodule_status::Error` (`gix/src/status/index_worktree.rs`) — all three transparent variants become plain `.map_err(gix_error::Error::from_error)` at their call sites in `BuiltinSubmoduleStatus::status()`. `gix::config::tree::Key::validate()` is a public trait method; erasing `validate::Error` changes its signature to return `gix_error::Error`, which downstream implementors of `Key` must now satisfy. This is expected and consistent with the `feat!` breaking-change marker used throughout this campaign. Also fixes a stale note: `submodule::status::Error`'s `TODO(review)` (`gix/src/submodule/mod.rs`) cited `status::index_worktree::submodule_status::Error::SubmoduleStatus` as its sole collision-free `#[from]` parent; that variant no longer exists once `submodule_status::Error` is a type alias, so the now-inaccurate clause is dropped. The note's actual justification (callers match `Error::State(...)` directly) is unaffected and unchanged.

It compiles and passes the test suite, so the compiler cannot catch it; these were found by resolving each call site's callee through its alias chain. Collapse eight such sites to a plain `?`: - `status::iter` -> `BuiltinSubmoduleStatus::new()` (`submodule::modules::Error`) - `repository::merge` -> `merge_pipeline_options()`, `merge_drivers()` and `diff_algorithm()` (three sites) - `repository::blame` -> `diff_algorithm()` - `commit` -> `commit_graph_if_enabled()` - `pathspec` -> `pathspec_defaults_inherit_ignore_case()` - `filter` -> `Core::CHECK_ROUND_TRIP_ENCODING::try_into_encodings()` (`config::encoding::Error`) Three of these live in `gix/src/repository/merge.rs`, which a bare `cargo check -p gix` does not compile at all; they are only visible with `--features merge`. Also corrects the `TODO(review)` note on `remote::find::existing::Error` (`gix/src/remote/errors.rs`), which claimed both its `#[from]` parents had no other erased member. Erasing `config::snapshot::credential_helpers::Error` spends the `From` slot of `env::collate::fetch::Error` via `CredentialHelperConfig`, so that type is now blocked by E0119 there in addition to its existing caller-match blocker. The claim about the other parent, `remote::find::for_fetch::Error`, still holds and is unchanged. --- gix/src/commit.rs | 5 +---- gix/src/filter.rs | 5 ++--- gix/src/pathspec.rs | 4 +--- gix/src/remote/errors.rs | 10 ++++++---- gix/src/repository/blame.rs | 2 +- gix/src/repository/merge.rs | 12 +++--------- gix/src/status/iter/mod.rs | 3 +-- 7 files changed, 15 insertions(+), 26 deletions(-) diff --git a/gix/src/commit.rs b/gix/src/commit.rs index 3fc7019dcd7..a6bb1a69099 100644 --- a/gix/src/commit.rs +++ b/gix/src/commit.rs @@ -225,10 +225,7 @@ pub mod describe { /// /// Prefer to use the [`Self::try_resolve_with_cache()`] method when processing more than one commit at a time. pub fn try_resolve(&self) -> Result>, Error> { - let cache = self - .repo - .commit_graph_if_enabled() - .map_err(gix_error::Error::from_error)?; + let cache = self.repo.commit_graph_if_enabled()?; self.try_resolve_with_cache(cache.as_ref()) } diff --git a/gix/src/filter.rs b/gix/src/filter.rs index 0ee9b6f5d57..c8ad6c6dc29 100644 --- a/gix/src/filter.rs +++ b/gix/src/filter.rs @@ -55,9 +55,8 @@ impl<'repo> Pipeline<'repo> { /// Extract options from `repo` that are needed to properly drive a standard git filter pipeline. pub fn options(repo: &'repo Repository) -> Result { let config = &repo.config.resolved; - let encodings = Core::CHECK_ROUND_TRIP_ENCODING - .try_into_encodings(config.string("core.checkRoundtripEncoding")) - .map_err(gix_error::Error::from_error)?; + let encodings = + Core::CHECK_ROUND_TRIP_ENCODING.try_into_encodings(config.string("core.checkRoundtripEncoding"))?; let safe_crlf = config .string("core.safecrlf") .map(|value| Core::SAFE_CRLF.try_into_safecrlf(value)) diff --git a/gix/src/pathspec.rs b/gix/src/pathspec.rs index 25bc3a3ef00..4ab57eb418a 100644 --- a/gix/src/pathspec.rs +++ b/gix/src/pathspec.rs @@ -31,9 +31,7 @@ impl<'repo> Pathspec<'repo> { inherit_ignore_case: bool, make_attributes: impl FnOnce() -> Result>, ) -> Result { - let defaults = repo - .pathspec_defaults_inherit_ignore_case(inherit_ignore_case) - .map_err(gix_error::Error::from_error)?; + let defaults = repo.pathspec_defaults_inherit_ignore_case(inherit_ignore_case)?; let patterns = patterns .into_iter() .map(move |p| parse(p.as_ref(), defaults)) diff --git a/gix/src/remote/errors.rs b/gix/src/remote/errors.rs index 24517c4228d..dccb4175b86 100644 --- a/gix/src/remote/errors.rs +++ b/gix/src/remote/errors.rs @@ -8,10 +8,12 @@ pub mod find { use crate::bstr::BString; // TODO(review): kept concrete.

Record what the migration actually became — a two-tier strategy. Plumbing crates drop `thiserror` for hand-written `Display`/`Error` impls on concrete enums and take no `gix-error` dependency; the `gix` boundary erases to `pub type Error = gix_error::Error;` where callers do not need to match variants. Add the two findings that cost the most to discover and appear nowhere in the original plan: the four structural blockers that keep a type concrete, and the double-wrap trap, where wrapping an already-erased error compiles and passes the suite while nesting an error inside itself. Note that the E0119 blocker is order-dependent rather than permanent — erasing a hub enum deletes it and frees everything it pinned. --- etc/plan/gix-error.md | 85 +++++++++++++++++++++++++++++-------------- 1 file changed, 58 insertions(+), 27 deletions(-) diff --git a/etc/plan/gix-error.md b/etc/plan/gix-error.md index 352727071e5..32e4e10a67c 100644 --- a/etc/plan/gix-error.md +++ b/etc/plan/gix-error.md @@ -22,16 +22,16 @@ Finish the migration from `thiserror`-based error enums to `gix-error` / `Exn`, - [x] Proof of concept completed in [#2352](https://github.com/GitoxideLabs/gitoxide/pull/2352), merged on January 12, 2026. - [x] `anyhow` / source-chain integration completed in [#2383](https://github.com/GitoxideLabs/gitoxide/pull/2383), merged on January 19, 2026. -- [ ] Make `cargo nextest --workflow` run without `--exclude gix-error`. - Evidence: `.github/workflows/ci.yml` still excludes `gix-error`. +- [ ] Make `cargo nextest run --workspace` complete without `--exclude gix-error`. + Evidence: `.github/workflows/ci.yml` still excludes `gix-error`, in three places (`ci.yml:304,364,450`).

No `gix-error` dependency at all. -- **`gix-error` adopters** — take a `gix-error` dependency directly and use its types (e.g. `gix_error::ValidationError`) in their own public error surface, short of the full erasure below. 16 crates do this (`gix-date` most completely — its entire public error is `pub use gix_error::ValidationError as Error;`, `gix-date/src/lib.rs:36`); `gix` is among them too, on top of anchoring the boundary tier next. +- **`gix-error` adopters** — take a `gix-error` dependency directly and use its types (e.g. `gix_error::ValidationError`) in their own public error surface, short of the full erasure below. 14 crates do this (`gix-date` most completely — its entire public error is `pub use gix_error::ValidationError as Error;`, `gix-date/src/lib.rs:36`): `gix-actor`, `gix-archive`, `gix-bitmap`, `gix-blame`, `gix-chunk`, `gix-commitgraph`, `gix-date`, `gix-mailmap`, `gix-pack`, `gix-quote`, `gix-refspec`, `gix-revision`, `gix-revwalk` and `gix-worktree-stream`. (A raw dependency-key count of `gix-error` across the workspace runs to 16 — the other two are `gix-error` itself, which defines these types rather than adopting them, and `gix`, which anchors the boundary tier next.) - **The `gix` boundary** — erase to `pub type Error = gix_error::Error;` where callers don't need to match variants. `Exn` itself is not rare in `gix` — it appears 33 times across 7 files (`lib.rs`, `repository/reference.rs`, `config/tree/keys.rs`, `revision/spec/parse/mod.rs`, and `revision/spec/parse/delegate/{mod,navigate,revision}.rs`), with the revision-spec delegate layer alone holding roughly 14 function signatures returning `Result<_, Exn>` — core parsing plumbing, not config/test downcasting.

Order-dependent, not permanent — erasing the *hub* enum that's holding the slot deletes it and frees everything it was pinning, so a blocker here can evaporate later in the campaign. 3. **Generic.** The type carries a type parameter (e.g. a caller-supplied source error `E`) that a `pub type` alias can't carry. 4. **E0117, orphan rule.** A local `impl for Error` (e.g. `gix_transport::IsSpuriousError`, re-exported through `gix_protocol::transport`) becomes foreign-trait-on-foreign-type once `Error` is an alias to the equally-foreign `gix_error::Error`. +Thirteen of the 42 cite more than one bucket, and the reasons stack rather than replace each other. Five cite three: `gix/src/remote/connect.rs:16`, `gix/src/remote/connection/ref_map.rs:12`, `gix/src/remote/connection/fetch/error.rs:3` and `gix/src/remote/connection/fetch/mod.rs:104` all open "kept concrete, blocked three independent ways" over buckets 4, 2 and 1; `gix/src/env.rs:54` (`env::collate::fetch::Error`) makes the same three-way case in prose rather than a numbered list, over buckets 3, 4 and 1. Eight more cite two, each signaled by a `Separately, …` clause except one argued in two unconnected sentences: `gix/src/config/mod.rs:62` and `gix/src/config/mod.rs:268` are two different types in the same file, over buckets 1+2 and 3+4 respectively; `gix/src/open/mod.rs:43`, `gix/src/reference/errors.rs:95`, `gix/src/remote/errors.rs:10` and `gix/src/status/iter/mod.rs:240` each cite buckets 1+2, as do `gix/src/submodule/errors.rs:27` and `gix/src/submodule/errors.rs:74`, two different types in the same file. The remaining 29 cite exactly one. + ### The double-wrap trap `.map_err(gix_error::Error::from_error)?` (equally `.or_raise(...)` / `.ok_or_raise(...)`) applied to a callee that *already* returns `gix_error::Error` nests one erased error inside another. It compiles and passes the full test suite — the compiler can't see it structurally, and tests don't catch it either, since the nested error still renders and downcasts fine one level down. Eight such sites are recorded fixed on this branch, in the `fix: collapse double-wrapped erased errors and correct a stale note` commit (`status::iter`; three in `repository::merge`; `repository::blame`; `commit`; `pathspec`; `filter`) — three of them inside `gix/src/repository/merge.rs`, which a bare `cargo check -p gix` does not compile at all, since `merge` is not a default feature (verified: absent from `default`, `basic`, `extras` and `comfort`; only pulled in by the non-default `need-more-recent-msrv` bundle). The campaign-wide count may be higher; eight is what this branch evidences.

They are about 4% of it. The growth is in the plumbing crates, where dropping `thiserror` meant writing out by hand the `Display` and `Error` impls it used to generate. Give the per-crate figures and drop the suggestion that moving the notes into this file would recover the difference; it would move some 260 lines against a total near 6,000.
