From f1a3a64b65605ae7302d4b8ee755da718ce945ab Mon Sep 17 00:00:00 2001 From: Dennis Heimbigner Date: Thu, 10 Aug 2023 16:57:57 -0600 Subject: [PATCH 1/2] Cleanup the handling of cache parameters. re: https://github.com/Unidata/netcdf-c/issues/2733 When addressing the above issue, I noticed that there was a disconnect in NCZarr between nc_set_chunk_cache and nc_set_var_chunk cache. Specifically, setting nc_set_chunk_cache had no impact on the per-variable cache parameters when nc_set_var_chunk_cache was not used. So, modified the NCZarr code so that the per-variable cache parameters are set in this order (#1 is first choice): 1. The values set by nc_set_var_chunk_cache 2. The values set by nc_set_chunk_cache 3. The defaults set by configure.ac --- CMakeLists.txt | 17 +++++++----- RELEASE_NOTES.md | 1 + config.h.cmake.in | 17 +++++++----- configure.ac | 58 +++++++++++++++++++-------------------- libhdf5/nc4hdf.c | 4 +-- libnczarr/zcache.h | 3 +- libnczarr/zinternal.h | 4 +-- libnczarr/zvar.c | 12 ++++---- libnczarr/zxcache.c | 24 ++++++++++------ libsrc4/nc4internal.c | 6 ++-- nc_test4/tst_chunks.c | 8 ++++-- nczarr_test/tst_zchunks.c | 2 +- 12 files changed, 88 insertions(+), 68 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 89bc521931..e8d4b30c1f 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -364,14 +364,17 @@ ENDIF() # Option checks ################################ -# HDF5 cache variables. +# Default Cache variables.
