 # Changelog

+## 2.3.0
+
+- Add `cache-all-crates` option, which enables caching of crates installed by workflows.
+- Add installed packages to cache key, so changes to workflows that install rust tools are detected and cached properly.
+- Fix cache restore failures due to upstream bug.
+- Fix `EISDIR` error due to globed directories.
+- Update runtime `@actions/cache`, `@actions/io` and dev `typescript` dependencies.
+- Update `npm run prepare` so it creates distribution files with the right line endings.
+
+## 2.2.1
+
+- Update `@actions/cache` dependency to fix usage of `zstd` compression.
+
+## 2.2.0
+
+- Add new `save-if` option to always restore, but only conditionally save the cache.
+
+## 2.1.0
+
+- Only hash `Cargo.{lock,toml}` files in the configured workspace directories.
+
+## 2.0.2
+
+- Avoid calling `cargo metadata` on pre-cleanup.
+- Added `prefix-key`, `cache-directories` and `cache-targets` options.
+
+## 2.0.1
+
+- Primarily just updating dependencies to fix GitHub deprecation notices.
+
+## 2.0.0
+
+- The action code was refactored to allow for caching multiple workspaces and
+  different `target` directory layouts.
+- The `working-directory` and `target-dir` input options were replaced by a
+  single `workspaces` option that has the form of `$workspace -> $target`.
+- Support for considering `env-vars` as part of the cache key.
+- The `sharedKey` input option was renamed to `shared-key` for consistency.
+
+## 1.4.0
+
+- Clean both `debug` and `release` target directories.
+
 ## 1.3.0

 - Use Rust toolchain file as additional cache key.

+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

-An optional key that is added to the automatic cache key.
-
-: `sharedKey`
-An additional key that is stable over multiple jobs.
-
-: `working-directory`
-The working directory the action operates in, is case the cargo project is not
-located in the repo root.
-
-: `target-dir`
-The target directory that should be cleaned and persisted, defaults to `./target`.
+Further examples are available in the [.github/workflows](./.github/workflows/) directory.

 ## Outputs

 Usage with Stable Rust is most effective, as a cache is tied to the Rust version.
 Using it with Nightly Rust is less effective as it will throw away the cache every day.

 ## Cache Details

-The cache currently caches the following directories:
+This action currently caches the following files/directories:

- `~/.cargo/registry/index`
- `~/.cargo/registry/cache`
- `~/.cargo/git`
- `./target`
+- `~/.cargo` (installed binaries, the cargo registry, cache, and git dependencies)
+- `./target` (build artifacts of dependencies)

 This cache is automatically keyed by:

- the github `job`,
- the rustc release / host / hash, and
- a hash of the `Cargo.lock` / `Cargo.toml` files (if present).
- a hash of the `rust-toolchain` / `rust-toolchain.toml` files (if present).
+- the github [`job_id`](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_id),
+- the rustc release / host / hash,
+- the value of some compiler-specific environment variables (eg. RUSTFLAGS, etc), and
+- a hash of all `Cargo.lock` / `Cargo.toml` files found anywhere in the repository (if present).
+- a hash of all `rust-toolchain` / `rust-toolchain.toml` files in the root of the repository (if present).
+- a hash of installed packages as generated by `cargo install --list`.

 An additional input `key` can be provided if the builtin keys are not sufficient.

-Before persisting, the cache is cleaned of intermediate artifacts and
-anything that is not a workspace dependency.
-In particular, no caching of workspace crates will be done. For
-this reason, this action will automatically set `CARGO_INCREMENTAL=0` to
-disable incremental compilation.
+Before being persisted, the cache is cleaned of:
+
+- Any files in `~/.cargo/bin` that were present before the action ran (for example `rustc`).
+- Dependencies that are no longer used.
+- Anything that is not a dependency.
+- Incremental build artifacts.
+- Any build artifacts with an `mtime` older than one week.
+
+In particular, the workspace crates themselves are not cached since doing so is
+[generally not effective](https://github.com/Swatinem/rust-cache/issues/37#issuecomment-944697938).
+For this reason, this action automatically sets `CARGO_INCREMENTAL=0` to disable
+incremental compilation, so that the Rust compiler doesn't waste time creating
+the additional artifacts required for incremental builds.
+
+The `~/.cargo/registry/src` directory is not cached since it is quicker for Cargo
+to recreate it from the compressed crate archives in `~/.cargo/registry/cache`.

 The action will try to restore from a previous `Cargo.lock` version as well, so
 lockfile updates should only re-build changed dependencies.

+The action invokes `cargo metadata` to determine the current set of dependencies.
+
 Additionally, the action automatically works around
 [cargo#8603](https://github.com/rust-lang/cargo/issues/8603) /
 [actions/cache#403](https://github.com/actions/cache/issues/403) which would
 otherwise corrupt the cache on macOS builds.
+
+## Cache Limits and Control
+
+This specialized cache action is built on top of the upstream cache action
+maintained by GitHub. The same restrictions and limits apply, which are
+documented here:
+https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows
+
+In particular, caches are currently limited to 10 GB in total and exceeding that
+limit will cause eviction of older caches.
+
+Caches from base branches are available to PRs, but not across unrelated
+branches.
+
+The caches can be controlled using the [Cache API](https://docs.github.com/en/rest/actions/cache)
+which allows listing existing caches and manually removing entries.
+
+## Debugging
+
+The action prints detailed information about which information it considers
+for its cache key, and it outputs more debug-only information about which
+cleanup steps it performs before persisting the cache.
+
+You can read up on how to [enable debug logging](https://docs.github.com/en/actions/monitoring-and-troubleshooting-workflows/enabling-debug-logging)
+to see those details as well as further details related to caching operations.
+
+## Known issues
+
+- The cache cleaning process currently removes all the files from `~/.cargo/bin`
+  that were present before the action ran (for example `rustc`).

Steven Hartland	7c7e41ab01	chore: changelog v2.3.0 (#139 ) Update CHANGELOG for v2.3.0 release.	2023-05-13 12:13:40 +02:00
Steven Hartland	68aeeba167	chore: use linefix to ensure platform line endings (#135 ) Use linefix so that when developing changes the results of npm run prepare always have unix line endings so git diff commands don't show line ending changes for the ncc generated files.	2023-05-11 23:19:46 +02:00
Steven Hartland	def0926359	feat: add option to cache all crates (#137 ) Add cache-all-crates option which allows all crates to be cached instead of just the dependency crates. This is useful when additional crates are required for CI tooling.	2023-05-11 23:15:09 +02:00
Steven Hartland	827c240e23	fix: cache key dependency on installed packages (#138 ) Add the installed packages to the environment element of the cache key so that CI tooling is considered. This ensures that rust CI tooling is cached correctly when changes occur. Prior to this a manual key change or cache expiry would need to occur before CI tools were correctly cached.	2023-05-11 23:12:12 +02:00
Steven Hartland	5e9fae966f	fix: cache restore failures (#136 ) Fix cache restore failures to to upstream bug. Fixes #119	2023-05-11 09:01:27 +02:00
