Brad King e48796b26b KWSys: Fix SystemTools environment memory handling (#13156)
The SystemTools::PutEnv function tries to provide the "putenv" API
without leaking memory.  However, the kwsysDeletingCharVector singleton
frees memory that may still be referenced by the environment table,
having been placed there by putenv.  If any static destruction or
processing by an external tool happens after the singleton is destroyed
and accesses the environment it will read invalid memory.

Replace use of putenv with setenv/unsetenv when available.  The latter
manage internal copies of the values passed instead of referencing the
original memory.  When setenv/unsetenv are not available use putenv with
a singleton that removes its values from the environment before freeing
their memory.  This requires an "unputenv" implementation.  On at least
some platforms it must be written in terms of "putenv" because other
APIs are not available and direct modification of the "environ" global
is not safe (e.g. on Windows there is interaction with "wenviron").
Fortunately either putenv("A=") or putenv("A") will remove "A" from the
environment on these platforms.  On other platforms fall back to direct
manipulation of "environ".

Also add UnPutEnv to the API and add a test for the behavior of both.

Brad King 74e1156bc2 KWSys: Simplify SystemTools::GetTime implementation (#12261)
We already use GetSystemTimeAsFileTime() and gettimeofday()
unconditionally on supported Windows and non-Windows platforms,
respectively.  Remove outdated portability complexity.

Brad King 3bf1869c93 KWSys: Improve SplitPath method documentation
Document explicitly that the first component always exists.  Fix the
documentation of SplitPathRootComponent to note that home directory
roots (~/ and ~u/) always have a trailing slash.

Brad King ac17dc4a43 KWSys: Remove "copyPermissions" parameters
The CopyFileIfDifferent, CopyFileAlways, CopyAFile and CopyADirectory
methods should always copy permissions.  The special cases in which a
caller would pass copyPermissions=false should be handled at the call
site.  The parameter needlessly complicates the interface and semantics
of these methods.

Brad King de955e4b6d Convert KWSys to OSI-approved BSD License
This converts the KWSys license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the KWSys copyright to
cover the full development time range.

Brad King 9b6c3d0782 Optimize KWSys SystemTools::FileExists on Windows
We optimize this method by using the GetFileAttributesExA native Windows
API to check for file existence when possible.  For real Windows builds
we always use it.  For Cygwin we use cygwin_conv_to_win32_path to get a
native Windows path if possible and otherwise fall back to 'access'.

Cygwin-to-Windows path conversion and cache by Wojciech Migda.
See issue #8826.

Brad King 714d2fc04b ENH: Remove obscure method from KWSys SystemTools
This removes SystemTools::FileExistsInParentDirectories from KWSys since
it is a special-purpose method that is not generally useful.

Brad King ca096a4596 BUG: Fix GetRealPath when realpath fails
This patch from Philip Lowman teaches SystemTools::GetRealPath to deal
with paths that do not exist by dealing with the case that realpath
returns NULL.  See issue #8423.

David Cole 0fafdb7eb8 BUG: Do not copy permissions of files when making the copy in an install rule. If the source file was read-only, this prevents the subsequent set of the destination file's modification time, making the copied file always different in time-stamp than the original and always installing a new file with a new time stamp (but the same content) causing unnecessary downstream incremental rebuilds. As part of this fix, add an optional copyPermissions parameter to the SystemTools routines CopyFileIfDifferent, CopyFileAlways, CopyAFile and CopyADirectory. The copyPermissions parameter defaults to true to preserve the behavior of these routines for existing callers. 2008-12-18 10:43:24 -05:00
Brad King cea66664c5 ENH: Added WOW64 key view support to KWSys SystemTools' windows registry API.
- Add an argument to registry read/write/delete methods to specify
    a 32-bit or 64-bit view.
  - Default is the bit-ness of the running program.
  - See issue #7095.

Philippe Pebay f18ae2234c ENH: added two functions for URL parsing:
1. an "abridged" version that separates protocol from dataglom in
        an expression with the form protocol://dataglom
     2. a "full" version that parses protocol, username, password,
        hostname, port, and path in a standard URL (all of these variables
        are optional, except for protocol and hostname).
