It worked both with openssl-generated v1 (no version tag present) and v3 certificates (version tag present). I don't know if this is an cpu-architecture -dependent issue (I don't think so), nor I know how the ber_* library works, but FWICU the Context + Constructed stuff is handled as a tag prefix by the ber_get_int(), which then discards it when found and fetches the encapsulated value. Instead, ber_peek_tag() is probably more simple-minded in that it peeks the first word at the buffer pointer, which is the Context + Constructed prefix, not really the tag. I can of course be wrong, but with this patch I got i==2 from v3 certificates, which is the correct value. Giampaolo

There is no function call here, 'wait' is checking a subprocess's exit status. That's standard, and so is checking the return (not exit) status from a function as far as I know, but I'm not surprised if some shells have quirks. I noticed because I saw the patch entering master. Which is fine by me, except the patch may be a bit incomplete. Since $SEARCHRC is now the output from `cat`, it may be best to quote it here: > if test $SEARCHRC != 52 ; then -- Hallvard

An assert means there is a bug, either in your code or ours. Since this part of the library has been around for several years with no issues, that generally means it's a bug in your code. The way to handle this is to fix your code.

There were two bugs here: 1) the syncrepl_add_glue_ancestors was not constructing a valid DN for the empty-suffix case. 2) it shouldn't have tried to add glue entries in this case anyway, since the underlying DB was pulled out from under it. Both fixed now in master, please test. > #0 0x00002b7e51344265 in raise () from /lib64/libc.so.6 > #1 0x00002b7e51345d10 in abort () from /lib64/libc.so.6 > #2 0x00002b7e5133d6e6 in __assert_fail () from /lib64/libc.so.6 > #3 0x0000000000549546 in ldap_add_ext (ld=0xbba1bc0, dn=0x0, attrs=0xbeb7ed0, > sctrls=0x0, cctrls=0x0, msgidp=0x435224c4) at add.c:126 > #4 0x00000000004dbe6d in ldap_back_add (op=0x43523150, rs=0x43522770) > at add.c:102 > #5 0x0000000000481152 in overlay_op_walk (op=0x43523150, rs=0x43522770, > which=op_add, oi=0xb9eb6c0, on=0x0) at backover.c:671 > #6 0x00000000004816a7 in over_op_func (op=0x43523150, rs=0x43522770, > which=op_add) at backover.c:723 > #7 0x0000000000473706 in syncrepl_add_glue_ancestors (op=0x43523150, > e=0x2b7e56628fb8) at syncrepl.c:3149 > #8 0x000000000047384e in syncrepl_add_glue (op=0x43523150, e=0x2b7e56628fb8) > at syncrepl.c:3193 > #9 0x0000000000474795 in syncrepl_entry (si=0xb9eb1c0, op=0x43523150, > entry=0x0, modlist=0x43523ca0, syncstate=<value optimized out>, > syncUUID=<value optimized out>, syncCSN=0xbeb86e0) at syncrepl.c:2448 > #10 0x000000000047c39b in do_syncrep2 (ctx=<value optimized out>, > arg=<value optimized out>) at syncrepl.c:982 > #11 do_syncrepl (ctx=<value optimized out>, arg=<value optimized out>) > at syncrepl.c:1489 > #12 0x000000000041eee3 in connection_read_thread (ctx=0x43523da0, > argv=<value optimized out>) at connection.c:1276 > #13 0x00000000005412dc in ldap_int_thread_pool_wrapper (xpool=0xb8fa1c0) > at tpool.c:685 > #14 0x00002b7e510ff73d in start_thread () from /lib64/libpthread.so.0 > #15 0x00002b7e513e84bd in clone () from /lib64/libc.so.6 > > Note: this also happens with 2.4.23.

Probably a good idea. Thanks for the patch, but it's basically unusable. Never submit patches to generated files. Only patch the source files. configure is generated from configure.in by autoconf. aclocal.m4 is also generated by autoconf; the section you patched appears to come from the libtool sources. > The patch is just for reference, it also drops FreeBSD 2.x and FreeBSD 3.x > support but it's not complete. > > A libtool patched with git revision e94c6d6e0359d92f08f491f57e0ef3371e978952 > would also be required to build OpenLDAP properly. > > -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
