Comment 1 Edwin Zhai 2011-02-16 06:49:42 UTC

I checked the Jan 14 changesets.

Contacts used e-addressbook-factory to create DB file, but our db didn't support fast mutexes and caused failure:

"(e-addressbook-factory:346): libebookbackend-WARNING **: libdb error: architecture lacks fast mutexes: applications cannot be threaded
(e-addressbook-factory:346): libebookbackend-WARNING **: db_env_open failed with Invalid argument"

This bug occur when HAVE_MUTEX_THREADS not defined, but application try to use db_env_open with *_ENV_THREAD flag.

This issue of db only exists on mips, while x86/arm are okay. x86 is generic, and arm has "--with-mutex=ARM/gcc-assembly".

Do we need something similar for mips?

CC db's owner dongxiao.

BTW, I also checked latest master (6cb8fd6def4912e4aa76330649ba42a9ed2694fd), this issue got fixed. (maybe after mark hatle upgrading db @ e77207)

So mark it as fixed. Dongxiao can investigate it in future if needed.

Comment 2 Edwin Zhai 2011-02-16 19:31:59 UTC

I compared the db's log.do_configure from 4.2.52 to 5.1.19:

=== 4.2.52 ===
checking for mutexes... UNIX/fcntl
configure: WARNING: NO FAST MUTEXES FOUND FOR THIS COMPILER/ARCHITECTURE.

=== 5.1.19 ===
checking for mutexes... POSIX/pthreads/library
checking pthread.h usability... yes
checking pthread.h presence... yes
checking for pthread.h... yes
checking for main in -lpthread... yes
checking for atomic operations... no
checking for library containing sched_yield... none required
checking for library containing fdatasync... none required
checking for library containing getaddrinfo... none required
checking for library containing hstrerror... none required
checking for main in -lm... yes
checking for main in -lnsl... yes
checking for main in -lsocket... no


So maybe db failed to detect the pthread library? We can revisit it if this bug occur again in future.

This issue does *not* occur on sato/sdk qemumips image.
