* Improve `FileUtils.forceDelete()` tests on Windows On Windows, the `DeleteFile` Win32 API has a little quirk: it refuses to delete files with the legacy **DOS read-only attribute** set. (Because apparently 99% of Windows users don’t realize that “deleting a file” is actually an operation on the *directory*, not the file itself 😉). So the usual drill is: clear the read-only flag first, then delete. * Until JDK 25, `File.delete()` did this for you behind the scenes: it quietly stripped the flag before calling into `DeleteFile`. That meant your file might be left behind (with the flag missing) if the *real* ACLs didn’t allow deletion. * From JDK 25 onward, `File.delete()` doesn’t touch the flag anymore. If the bit is set, `DeleteFile` fails, end of story. * `FileUtils.forceDelete()` already knows how to juggle the flag itself, so its behavior didn’t change. This PR: * Updates two tests that were (unfairly) comparing `File.delete` with `FileUtils.forceDelete`. With JDK 25, their expectations diverged. * Adds a new test to confirm that `FileUtils.forceDelete` restores the read-only flag if the actual deletion fails. > [!WARNING] > I didn’t develop this on a Windows box, so I couldn’t test it locally. Leaving this as a **draft PR** until CI tells us whether Windows agrees with me. * fix: always clear read-only bit * fix: check for `IOException`, not `AccessDeniedException` * feat: add holder for file and parent attributes Introduce a helper that snapshots file and parent directory attributes before `setReadOnly` is applied. If a deletion attempt fails, the holder can restore the original attributes to keep the filesystem state consistent. * fix: Spotbugs failure * fix: prefer POSIX to DOS attributes when both are available On Linux/Unix, both POSIX and DOS attribute views may be supported, while on Windows only DOS attributes are available. Check for POSIX first to ensure the correct view is used across platforms. * fix: revert read-only related changes

* Add missing `read` argument validation in `IOUtils` In #790 I introduced `IOUtils#checkIndexFromLength` calls to validate arguments across the codebase. Ironically, the `IOUtils` class itself was left out. This PR addresses that omission by adding argument validation to `IOUtils#read` and `IOUtils#readFully`. Key points: * Ensures consistency with the rest of Commons IO by validating `offset` and `length`. * Fixes inconsistent exception behavior: * Previously, `length < 0` resulted in an `IllegalArgumentException`. * `offset < 0` did not trigger validation and failed later with an `IndexOutOfBoundsException`. * With this change, both invalid cases are handled consistently and upfront. * fix: failing tests
The implementation of `IOUtils.toByteArray(InputStream, int, int)` added in #776 throws different exceptions depending on the requested size: * For request sizes larger than the internal chunk size, it correctly throws an `EOFException`. * For smaller requests, it incorrectly throws a generic `IOException`. This PR makes the behavior consistent by always throwing an `EOFException` when the stream ends prematurely. Note: This also affects `RandomAccessFiles.read`. Its previous truncation behavior was undocumented and inconsistent with `RandomAccessFile.read` (which reads as much as possible). The new behavior is not explicitly documented here either, since it is unclear whether throwing on truncation is actually desirable.

category/java/errorprone.xml/UselessOperationOnImmutable as it is scheduled for removal from PMD. PMD 8.0.0 will remove support for this Rule.
This PR is split from #799. The `CloseShieldChannel` implementation only inspects interfaces **directly** implemented by the given channel’s class, ignoring those inherited from its superclasses. As a result, proxies for types such as `FileChannel` does not expose any of the interfaces declared on `FileChannel` itself.

* Fixes issues in `CloseShieldChannel`
Two bugs in the `CloseShieldChannel` helper make it unreliable in practice:
1. **Type-erasure bug in `T wrap(T)`**
The method signature only works correctly when `T` is an **interface** extending `Channel`.
Since Java’s type system doesn’t allow constraining `T` to “interface types only,” this could lead to unexpected runtime `ClassCastException`s even though the code compiles successfully.
2. **Incomplete interface discovery**
The implementation only inspected interfaces **directly** implemented by the given channel’s class, ignoring those inherited from its superclasses.
As a result, proxies for types such as `FileChannel` did not expose any of the interfaces declared on `FileChannel` itself.
#### Fixes
This PR addresses both issues:
* **Reworks the API signature**
* Replaces `T wrap(T)` with its erasure: `Channel wrap(Channel)`.
* Introduces a new overload: `T wrap(T, Class<T>)`, which allows callers to explicitly specify the interface type they expect.
This version fails fast with a clear `IllegalArgumentException` if the provided type is not an interface, instead of allowing a `ClassCastException` later.
* **Improves interface collection logic**
* Updates the implementation to include interfaces declared on superclasses, ensuring all relevant `Channel` interfaces are correctly proxied.
* Fixes interface discovery in `CloseShieldChannel`

* Fix concurrency issue in `IOUtils.skip` This patch addresses a concurrency problem in `IOUtils.skip`, as reported in [COMPRESS-666](https://issues.apache.org/jira/browse/COMPRESS-666) and [COMPRESS-697](https://issues.apache.org/jira/browse/COMPRESS-697). Previously, `IOUtils.skip` relied on `InputStream#read` to skip bytes, using a buffer shared across **all** threads. Although `IOUtils.skip` itself does not consume the data read, certain `InputStream` implementations (e.g. `ChecksumInputStream`) may process that data internally. In concurrent scenarios, this shared buffer could be overwritten by another thread between the `read` and the subsequent internal processing (such as checksum calculation), leading to incorrect behavior. This change reverts commit c12eaff and restores the use of a **per-thread buffer** in `IOUtils.skip`, ensuring thread safety and correct behavior in concurrent environments. * Adds a reentrancy guard to the thread-local pool * Apply suggestion from @Copilot (1) Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Apply suggestions from @Copilot (2) Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
