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
Since CMake's default compiler flags with MSVC include `-DWIN32` for
historical reasons, a few preprocessor conditions were accidentally
checking for `WIN32` instead of `_WIN32`. The corresponding blocks
were left out when compiling official binaries for `cmake.org` because
we hard-code compiler flags without `-DWIN32`.
Fixes: #22764
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.
Extend the fix from commit 7b8dcdd173 (CPack: Do not recurse through
directory symlinks (#12284), 2011-08-27, v2.8.6~55^2) to more places in
CPack.
Issue: #12284
Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.
Fixes: #19491
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)`
This replaces invocations of
- `cmSystemTools::IsInternallyOn` with `cmIsInternallyOn`
- `cmSystemTools::IsNOTFOUND` with `cmIsNOTFOUND`
- `cmSystemTools::IsOn` with `cmIsOn`
- `cmSystemTools::IsOff` with `cmIsOff`
`CollapseCombinedPath` was introduced by commit 551d3343cd (cmDependsC:
Collapse relative include paths, 2013-06-19, v2.8.12~237^2) where the
existing `CollapseFullPath` should have been used instead. Then its use
proliferated slightly. Since `CollapseCombinedPath` is less widely used
and less robust (see issue #19049), use `CollapseFullPath` everywhere
instead.
Issue: #19050
Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and
`Source/cmUVHandlePtr.h` where a few older compilers require a
user-defined default constructor (with `{}`).
