Use UTF-8 by default, as this has become common for cross-platform
archive distribution, and our previous default was platform-specific.
Also revert commit f590010167 (libarchive: Restore tolerance of archives
with non-OEM paths on Windows, 2026-01-23, v3.31.11~1^2). Its primary
purpose was to tolerate UTF-8 paths when extracting archives, which we
now handle by default.
Issue: #26903
When there are two files with the same name but different content, an
error is shown, but the error does not include the filename which caused
it. This adds the filename to the error.
Add `CPACK_ARCHIVE_UID` and `CPACK_ARCHIVE_GID` options.
Add a policy to change the default to 0/0 to enable ownership
by root if unpacking as root.
Fixes: #12901
The variable CPACK_ARCHIVE_FILE_NAME (added in 9e06e97d30)
only works if per-component packaging is enabled. This isn't obvious
from the documentation.
Make it also work for non-component packages and adjust documentation.
Fixes: #8769
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`, now with "east const" enforcement.
Use `clang-format` version 18.

Issue: #26123
CPack no longer blindly tries to create temporary packaging
(sub)directories that contain the verbatim name of a component, which
might contain characters that are not supported on the platform /
filesystem.
Instead, if the component's name contains a (possibly) problematic
character its MD5 hash will be used for that temporary packaging
(sub)directory.
Likewise, if the component's name resembles a reserved device name (e.g.
"COM1" on Windows) then the temporary packaging (sub)directory will get
this name prefixed with an underscore.
Similar, if it ends in a dot (on Windows) then the temporary packaging
(sub)directory will get this name suffixed with an underscore.
Fixes: #23612
Merge use of SetFilterOption() into more abstract thread count
in cmArchiveWrite constructor.
libarchive defaulting of threads for threads == 0 seems to be
configuration dependent. Preemptively default thread count via
std::thread::hardware_concurrency().
Also allow negative values for the thread count in which case
the detected hardware concurrency is also used but the given
absolute thread count is used as an upper limit.
This patch is generated by a python script that uses regular expressions to
search for string concatenation patterns of the kind
```
std::string str = <ARG0>;
str += <ARG1>;
str += <ARG2>;
...
```
and replaces them with a single `cmStrCat` call
```
std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...);
```
If any `<ARGX>` is itself a concatenated string of the kind
```
a + b + c + ...;
```
then `<ARGX>` is split into multiple arguments for the `cmStrCat` call.
If there's a sequence of literals in the `<ARGX>`, then all literals in the
sequence are concatenated and merged into a single literal argument for
the `cmStrCat` call.
Single character strings are converted to single char arguments for
the `cmStrCat` call.
`std::to_string(...)` wrappings are removed from `cmStrCat` arguments,
because it supports numeric types as well as string types.
`arg.substr(x)` arguments to `cmStrCat` are replaced with
`cm::string_view(arg).substr(x)`
Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and
`Source/cmUVHandlePtr.h` where a few older compilers require a
user-defined default constructor (with `{}`).
After changing the ``cmGeneratedFileStream`` methods to accept
``std::string const&`` instead of ``const char*`` we don't
need to call ``std::string::c_str`` anymore when passing
a ``std::string`` to a ``cmGeneratedFileStream`` method.
This patch removes all redundant ``std::string::c_str``
calls when passing a string to a ``cmGeneratedFileStream`` method.
It was generated by building CMake with clang-tidy enabled using
the following options:
-DCMAKE_CXX_CLANG_TIDY=/usr/bin/clang-tidy-4.0;-checks=-*,readability-redundant-string-cstr;-fix;-fix-errors
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 6.0.

* Change some functions to take `std::string` instead of
`const char*` in the following classes: `cmMakeFile`, `cmake`,
`cmCoreTryCompile`, `cmSystemTools`, `cmState`, `cmLocalGenerator`
and a few others.
* Greatly reduce using of `const char*` overloads for
`cmSystemTools::MakeDirectory` and `cmSystemTools::RelativePath`.
* Remove many redundant `c_str()` conversions throughout the code.
These functions just need to change the directory for a block of code
and then go back to the caller's expected location. Use
cmWorkingDirectory to ensure that all return paths are handled.
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
