2023-02-15JSON internal API, IEEE754 base64/hex streaming, weights endpoint ↵Costa Tsaousis
optimization (#14493) * first work on standardizing json formatting * renamed old grouping to time_grouping and added group_by * add dummy functions to enable compilation * buffer json api work * jsonwrap opening with buffer_json_X() functions * cleanup * storage for quotes * optimize buffer printing for both numbers and strings * removed ; from define * contexts json generation using the new json functions * fix buffer overflow at unit test * weights endpoint using new json api * fixes to weights endpoint * check buffer overflow on all buffer functions * do synchronous queries for weights * buffer_flush() now resets json state too * content type typedef * print double values that are above the max 64-bit value * str2ndd() can now parse values above UINT64_MAX * faster number parsing by avoiding double calculations as much as possible * faster number parsing * faster hex parsing * accurate printing and parsing of double values, even for very large numbers that cannot fit in 64bit integers * full printing and parsing without using library functions - and related unit tests * added IEEE754 streaming capability to enable streaming of double values in hex * streaming and replication to transfer all values in hex * use our own str2ndd for set2 * remove subnormal check from ieee * base64 encoding for numbers, instead of hex * when increasing double precision, also make sure the fractional number printed is aligned to the wanted precision * str2ndd_encoded() parses all encoding formats, including integers * prevent uninitialized use * /api/v1/info using the new json API * Fix error when compiling with --disable-ml * Remove redundant 'buffer_unittest' declaration * Fix formatting * Fix formatting * Fix formatting * fix buffer unit test * apps.plugin using the new JSON API * make sure the metrics registry does not accept negative timestamps * do not allow pages with negative timestamps to be loaded from db files; do not accept pages with negative timestamps in the cache * Fix more formatting --------- Co-authored-by: Stelios Fragkakis <52996999+stelfrag@users.noreply.github.com>

2022-10-09Remove extern from function declared in headers. (#13790)vkalintiris
By default functions are declared as extern in C/C++ headers. The goal of this PR is to reduce the wall of text that many headers have and, more importantly, to make the declaration of extern'd variables - of which we have many dispersed in various places - easily and quickly identifiable. Automatically generated with: $ git grep -l '^extern.*(' '**.h' | \ grep -v libjudy | \ grep -v 'sqlite3.h' | \ xargs sed -i -e 's/extern \(.*(.*$\)/\1/' This is a NFC.
