Have you tried to use the yet-to-be-released ccache with MSVC ? Also, do you know about msbuild /outputResultsCache ? When I tried that, it gave a bunch of error.

When I tried, it refused to cache because of our debug settings (DebugInformationFormat) - which seem to be enabled even in release mode. I wonder if that'll be an issue for ccache, too. I think that line may need to be conditional on debug mode. https://cirrus-ci.com/task/4808554103177216 |[17:14:28.765] C:\ProgramData\chocolatey\lib\clcache\clcache\clcache.py Expanded commandline '['/c', '/Isrc/include', '/Isrc/include/port/win32', '/Isrc/include/port/win32_msvc', '/Ic:/openssl/1.1/\\include', '/Zi', '/nologo', '/W3', '/WX-', '/diagnostics:column', '/Ox', '/D', 'WIN32', '/D', '_WINDOWS', '/D', '__WINDOWS__', '/D', '__WIN32__', '/D', 'WIN32_STACK_RLIMIT=4194304', '/D', '_CRT_SECURE_NO_DEPRECATE', '/D', '_CRT_NONSTDC_NO_DEPRECATE', '/D', 'FRONTEND', '/D', '_MBCS', '/GF', '/Gm-', '/EHsc', '/MD', '/GS', '/fp:precise', '/Zc:wchar_t', '/Zc:forScope', '/Zc:inline', '/Fo.\\Release\\libpgcommon\\', '/Fd.\\Release\\libpgcommon\\libpgcommon.pdb', '/external:W3', '/Gd', '/TC', '/wd4018', '/wd4244', '/wd4273', '/wd4101', '/wd4102', '/wd4090', '/wd4267', '/FC', '/errorReport:queue', '/MP', 'src/common/archive.c', 'src/common/base64.c', 'src/common/checksum_helper.c', 'src/common/config_info.c', 'src/common/controldata_utils.c', 'src/common/cryptohash_openssl.c', 'src/common/d2s.c', 'src/common/encnames.c', 'src/common/exec.c', 'src/common/f2s.c', 'src/common/fe_memutils.c', 'src/common/file_perm.c', 'src/common/file_utils.c', 'src/common/hashfn.c', 'src/common/hmac_openssl.c', 'src/common/ip.c', 'src/common/jsonapi.c', 'src/common/keywords.c', 'src/common/kwlookup.c', 'src/common/link-canary.c', 'src/common/logging.c', 'src/common/md5_common.c', 'src/common/pg_get_line.c', 'src/common/pg_lzcompress.c', 'src/common/pg_prng.c', 'src/common/pgfnames.c', 'src/common/protocol_openssl.c', 'src/common/psprintf.c', 'src/common/relpath.c', 'src/common/restricted_token.c', 'src/common/rmtree.c', 'src/common/saslprep.c', 'src/common/scram-common.c', 'src/common/sprompt.c', 'src/common/string.c', 'src/common/stringinfo.c', 'src/common/unicode_norm.c', 'src/common/username.c', 'src/common/wait_error.c', 'src/common/wchar.c']' |[17:14:28.765] C:\ProgramData\chocolatey\lib\clcache\clcache\clcache.py Cannot cache invocation as ['/c', '/Isrc/include', '/Isrc/include/port/win32', '/Isrc/include/port/win32_msvc', '/Ic:/openssl/1.1/\\include', '/Zi', '/nologo', '/W3', '/WX-', '/diagnostics:column', '/Ox', '/D', 'WIN32', '/D', '_WINDOWS', '/D', '__WINDOWS__', '/D', '__WIN32__', '/D', 'WIN32_STACK_RLIMIT=4194304', '/D', '_CRT_SECURE_NO_DEPRECATE', '/D', '_CRT_NONSTDC_NO_DEPRECATE', '/D', 'FRONTEND', '/D', '_MBCS', '/GF', '/Gm-', '/EHsc', '/MD', '/GS', '/fp:precise', '/Zc:wchar_t', '/Zc:forScope', '/Zc:inline', '/Fo.\\Release\\libpgcommon\\', '/Fd.\\Release\\libpgcommon\\libpgcommon.pdb', '/external:W3', '/Gd', '/TC', '/wd4018', '/wd4244', '/wd4273', '/wd4101', '/wd4102', '/wd4090', '/wd4267', '/FC', '/errorReport:queue', '/MP', 'src/common/archive.c', 'src/common/base64.c', 'src/common/checksum_helper.c', 'src/common/config_info.c', 'src/common/controldata_utils.c', 'src/common/cryptohash_openssl.c', 'src/common/d2s.c', 'src/common/encnames.c', 'src/common/exec.c', 'src/common/f2s.c', 'src/common/fe_memutils.c', 'src/common/file_perm.c', 'src/common/file_utils.c', 'src/common/hashfn.c', 'src/common/hmac_openssl.c', 'src/common/ip.c', 'src/common/jsonapi.c', 'src/common/keywords.c', 'src/common/kwlookup.c', 'src/common/link-canary.c', 'src/common/logging.c', 'src/common/md5_common.c', 'src/common/pg_get_line.c', 'src/common/pg_lzcompress.c', 'src/common/pg_prng.c', 'src/common/pgfnames.c', 'src/common/protocol_openssl.c', 'src/common/psprintf.c', 'src/common/relpath.c', 'src/common/restricted_token.c', 'src/common/rmtree.c', 'src/common/saslprep.c', 'src/common/scram-common.c', 'src/common/sprompt.c', 'src/common/string.c', 'src/common/stringinfo.c', 'src/common/unicode_norm.c', 'src/common/username.c', 'src/common/wait_error.c', 'src/common/wchar.c']: external debug information (/Zi) is not supported -- Justin
