- The change to "content" and "content-timestamp" Decider names is reflected
in the User Guide as well, since the hash function may be other than md5
(tidying up from earlier change)
- If SCONS_CACHE_MSVC_CONFIG is used, it will now attempt a sanity check for
the cached compiler information, and regenerate the information
if needed, rather than just failing after certain compiler version
changes have happened. The cache file can still be manually removed
if there are issues to force a regen. The default cache filename now
has a .json suffix - the contents have always been json.
- If the (experimental) SCONS_CACHE_MSVC_CONFIG feature is used, it will now
attempt a sanity check for the cached compiler information, and regenerate
it if needed. Previously, this cache would fail if a compiler upgrade caused
a change to internal paths (e.g. upgrading from 17.1 to 17.2 causes
a necessary path component in some of the cached vars to need to 14.32.31326
instead of 14.31.31103), and the cache file needed to be manually removed.
The default cachefile name is now "scons_msvc_cache.json" rather than
".scons_msvc_cache" so there should be no transition problem if using the
default; if using a custom cache file name, the cache should still be
manually removed if there are problems to transition to the new style.
- Update ninja file generation to only create response files for build commands
which exceed MAXLINELENGTH
- Update the debug output written to stdout for MSVC initialization which is enabled
