(ITS#8511) Rename "mirrormode" to "multimaster", deprecate "mirrormode" parameter
by quanah＠openldap.org 07 Oct '16

07 Oct '16

Full_Name: Quanah Gibson-Mount Version: 2.4.44 OS: N/A URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (47.208.148.26) In bconfig.c, the following should be reworked: { "mirrormode", "on|off", 2, 2, 0, ARG_DB|ARG_ON_OFF|ARG_MAGIC|CFG_MIRRORMODE, &config_generic, "( OLcfgDbAt:0.16 NAME 'olcMirrorMode' " So that the parameter name is multimaster, and the config attr is olcMultiMaster The term "mirrormode" is both confusing and misleading, as what it really controls is whether or not this node is enabled for multimaster.

(ITS#8509) LMDB make targets for automake

Full_Name: Aido Version: 2.4.44 OS: Ubuntu Trusty URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (216.239.90.19) The current liblmdb Makefile does not make it easy to use liblmdb as a submodule to other projects that utilize automake e.g. automake uses a 'check' directive instead of 'test'. Adding the following to the Makefile would make liblmdb more automake friendly: EMPTY_AUTOMAKE_TARGETS = dvi pdf ps info html tags ctags distcheck .PHONY: $(EMPTY_AUTOMAKE_TARGETS) $(EMPTY_AUTOMAKE_TARGETS): check: test See: https://www.gnu.org/software/automake/manual/html_node/Third_002dParty-Make…

(ITS#8508) PATCH - ucgendat.c properly add title-case characters without upper-case equivalents (e.g. greek letters with iota subscript)
by z.figura12＠gmail.com 01 Oct '16

01 Oct '16

Full_Name: Zebediah Figura Version: trunk OS: (Kubuntu 16.04) URL: ftp://ftp.openldap.org/incoming/zebediah-figura-160930.patch Submission from: (NULL) (132.161.178.173) The file ucgendat.c, which is used to generate a list of (among other things) Unicode case correspondences, only generates correspondences for the title-case characters which have both a corresponding lower-case and upper-case forms (ǅ, ǈ, ǋ, ǲ). This is because read_cdata() checks whether there exists both a lower-case and an upper-case form, but Unicode does not provide an upper-case form for title-case characters (Greek characters with iota subscript) which do not have a distinct upper-case form. Thus these are mistakenly treated as upper-case characters. I have attached a patch which causes read_cdata() to treat a character as title-case if it has the property Lt (i.e. Letter, title) and has either an upper-case or lower-case form defined.
