Support readonly MDB slaptools on readonly filesystems

by Hallvard Breien Furuseth

Back-mdb needs this test, copied from libmdb, to make use of the libmdb support for read-only filesystems. I don't know if Windows sets errno=EROFS for fopen(fname, "w") when fname is on a read-only FS, if so the #ifndef _WIN32 is unnecessary. --- servers/slapd/back-mdb/config.c +++ servers/slapd/back-mdb/config.c @@ -561,3 +561,8 @@ mdb_cf_gen( ConfigArgs *c ) ch_free( testpath ); - if ( !f ) { +#ifndef _WIN32 + if ( !(f || ((slapMode & SLAP_TOOL_READONLY) && errno == EROFS)) ) +#else + if ( !(f || ((slapMode & SLAP_TOOL_READONLY) && GetLastError() == ERROR_WRITE_PROTECT)) ) +#endif + { snprintf( c->cr_msg, sizeof( c->cr_msg ), "%s: invalid path: %s", -- Hallvard

RE24 testing call #2 (OpenLDAP 2.4.33)

by Quanah Gibson-Mount

If you know how to build OpenLDAP manually, and would like to participate in testing the next set of code for the 2.4.33 release, please do so. Generally, get the code for RE24: <http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=snapshot;h=refs...> Configure & build. Execute the test suite (via make test) after it is built.

Manual should tell the data range of the configuration parameter

by Tianyin Xu

Hi, guys, I was quite confused with "index_intlen". ---------- what the manual says ---------- * * *index_intlen* <*integer*> Specify the key length for ordered integer indices. The most significant bytes of the binary integer will be used for index keys. The default value is 4, which provides exact indexing for 31 bit values. A floating point representation is used to index too large values. ------------------------------------------------------ Ok, what the manual told me is that 4 is the default value, and large values can be handled. But I finally figured out that 4 is not only the default value but also the minimum value. >From the source code, I knew the index_intlen is with the data range [4, 255]. Any out-of-range value will be converted to the boundaries without notifying users: #define SLAP_INDEX_INTLEN_DEFAULT 4 /* servers/slapd/bconfig.c */ static int config_generic(ConfigArgs *c) { ... case CFG_IX_INTLEN: if ( c->value_int < SLAP_INDEX_INTLEN_DEFAULT ) c->value_int = SLAP_INDEX_INTLEN_DEFAULT; else if ( c->value_int > 255 ) c->value_int = 255; index_intlen = c->value_int; ... } To my opinion, as a configuration knob for user tuning, such behavior (especially the range) should be explicitly exposed to users. I would suggest to make it explicit by 1. print out logs to notify users 2. write in the manual. * * Thanks a lot! Tianyin -- Tianyin XU, http://cseweb.ucsd.edu/~tixu/
