RRDtool Version 1.9.0

RRDtool 1.9.0 — 2024-07-29

Bugfixes

• Fix ytop and ybase adjustments for overlaping area issue on transparent areas @turban
• Suppress warnings of implicit fall through @youpong
• Update tarball download link in doc @c72578
• Fix unsigned integer overflow in rrdtool first. Add test for rrd_first() @c72578
• Fix tests under MSYS2 (Windows) @c72578
• Fix BUILD_DATE in rrdtool help output @c72578
• acinclude.m4: Include <stdlib.h> when using exit @ryandesign
• rrdtool-release: Create NUMVERS from VERSION file @c72578
• Avoids leaking of file descriptors in multi threaded programs by @ensc
• Avoids potential unterminated string because of fixed PATH_MAX buffer
• Fix extra reference of parameters of rrd_fetch_dbi_{long,double} @jamborm

Features

• Remove autogenerated files from git repo (configure, Makefile.in, conftools, rrd_config.h.in)

• Reads $RRD_LOCKING environment variable and adds --locking option to some tools. The updatex api has been also
  updated to support setting locking related bits in its extra_flags parameter. @ensc

  This allows now to choose between three kinds of locking:

  none: no locking is done at all; caller has to do it manually and can implement e.g., a timeout with alarm(2) or so
  try: fails when lock is hold by another process; users will see "ERROR: could not lock RRD". This is the default and the only possible mode with the old code
  block: waits until lock is available.

  It can be used like
  env RRD_LOCKING=block rrdupdate ...
  or
  rrdupdate --locking none ...
  or
  rrd_updatex_r(filename, tmplt, RRD_FLAGS_LOCKING_MODE_BLOCK, ...);

• Add (remote) dump support to rrdcached @thz

• Constify argv argument to library functions
  Without this, users of library function that want to pass in const strings need to duplicate them to avoid compiler warnings

• Avoid multiple implementations of asprintf
  The locale-independent rrd_asprintf is equivalent to platform-provided snprintf when strings and integers are formatted.
  There is no user of vasprintf-msvc that is locale-dependent, therefore this implementation can be replaced with rrd_vasprintf.
