cf4fe3b1fb Microoptimize loose pages 2014-08-17 01:50:32 +02:00
Hallvard Furuseth
1e7eeed28d Fix loose pages in mdb_freelist_save(). 
Leaving them in dirty_list caused breakage.  Instead merge them
into me_pghead at the end, when no more pages will be allocated.

3630066843 Fix MIPS cache coherency on Linux 
MIPS chips require manual control of on-chip caches. The cacheflush
syscall being used here only exists on MIPS Linux, other OSs will
require revisiting.

bda6a60ad4 Windows fixes 
Always set the filesize when opening for writes. Otherwise
can't use backups from mdb_copy.

f3573a7383 Windows compat 
We mainly use Win32 functions, so cannot just use C-runtime strerror
to return error messages. We have to use Win32-specific messages.
Unfortunately, we document the API to return C-runtime error codes,
so we can't just switch to all Win32 error codes.

of already closed handle.

e1a676eb18 ITS#7713 cleanups 
'#ifdef MDB_DEVEL' -> '#if MDB_DEVEL'
Fix comments, use actual PAGEBASE macro as originally intended.
Actually enable 64K pages. Set MDB_DATA_VERSION for testing only.

6ed295b256 Fixes for loose pages 
mdb_txn_commit(child): Give loose pages to parent.
Use a pointer beyond the page header instead of mp_next, so
we will not need to save/restore mp_pgno. This avoids a crash
caused by references to mp_pgno.

Fix mp_lower/mp_upper to exclude PAGEHDRSZ, which means our
max mp_upper is now pagesize - PAGEHDRSZ and won't overflow.
Currently must define MDB_DEVEL to use. Will be default for
LMDB 1.0/OpenLDAP 2.5
