Add a CI workflow running fmt, clippy with warnings denied, and the test
suite on every push and pull request. Remove the unused workspace windows
dependency now that only windows-sys is used. Update the README architecture
name and Java harness reference, clarify the plans gitignore comment, and
carry the code-reviewer agent memory.
The earlier C# (EasyHook) and C++ (MS Detours) ports were merged into
this repo under csharp/ and cpp/ so their full histories stay reachable
(git log -- csharp/ cpp/). Their trees are removed from HEAD because
their IPC tick epoch (delta against DateTime.UtcNow.Ticks) is
incompatible with the Rust implementation's raw FILETIME contract —
keeping both in the working tree would present two contradictory IPC
designs side by side.
The Java test target remains in the working tree; README links now
point at in-repo paths instead of the retired port repositories.
Creating a `Global\TimeMocker_<pid>` mapping requires
`SeCreateGlobalPrivilege`, which an unelevated token (e.g. debug `cargo run`
where the UAC manifest is intentionally skipped) does not have, so
`CreateFileMappingW` returned NULL with `ERROR_ACCESS_DENIED` and the
auto-inject scanner spammed `create MMF Global\TimeMocker_<pid>` for every
enumerated PID.
The UI now tries `Global\` first and falls back to `Local\` on access
denied, with a one-shot log warning so the auto-inject loop doesn't
flood. The hook DLL probes both names on attach so the IPC pairs up
symmetrically. Release builds keep their elevated `Global\` cross-session
reach; debug builds work against same-session targets without admin.
Also adds a dedicated `time-mocker-test-target` crate — a small console
binary that prints all 5 hooked time APIs every second with its own PID
banner, so dev verification can inject into a controlled harness instead
of arbitrary running processes.
Repo renamed from tiennm99/time-mocker-rs to tiennm99/time-mocker.
README and workspace Cargo.toml updated to reflect the new canonical
identity; C# and C++ ports linked as language siblings.
Rust workspace with three crates:
- time-mocker-core: shared MockTimeInfo + named MMF helper + FILETIME helpers
- time-mocker-hook: cdylib injected into targets; inline detours via retour
on GetSystemTime / GetLocalTime / GetSystemTimeAsFileTime /
GetSystemTimePreciseAsFileTime / NtQuerySystemTime
- time-mocker-ui: egui controller with process list, time picker, and
glob/regex auto-inject rules; injects via dll-syringe; UAC manifest
embedded in release builds
IPC: 8-byte MMF named TimeMocker_<pid> holding an i64 delta in FILETIME
ticks. Hook adds delta to the real FILETIME on every call. Note this
differs from the C# version's .NET-tick delta -- contracts are not
interoperable.
Requires nightly toolchain (retour uses unboxed_closures / tuple_trait);
pinned via rust-toolchain.toml.
