b5e5fcc31d ITS#8582 Fill in MDB_LOCK_FORMAT 
Attempt to stop liblmdb variants compiled with conflicting options
from using the lockfile at the same time and thus breaking it.

172d825155 Simplify mdb_hash_val() -> mdb_hash() 
Simpler usage since it's only called once, rename to match new usage,
and drop 3 loop pessimizations which were optimizations 20 years ago.

68eda68f0b Store lock ID instead of pathname in lockfile 
This limits the namespace which the user can meddle with for
POSIX semaphores and Windows mutexes.  Their names change a
bit, they no longer have fixed lengths.

Optimize mdb_page_search_root(PS_LAST) when cursor is already near
last position, ignoring C_EOF flag for now.

4bc270a2cb More MDB_node doc 2016-12-21 21:42:36 +01:00
Hallvard Furuseth
be94a7565b Doxygen fixes. Use DISTRIBUTE_GROUP_DOC. 
- DISTRIBUTE_GROUP_DOC makes doxygen give several fields the
  same doc: mn_hi + mn_lo in MDB_node.
- With mdb_mutex_t + mdb_mutexref_t, instead split them up.
- Don't hide a doxygen #name inside double quotes.

e539654051 ITS#8504 Fix prev commit: mc_error, #ifdef SIGPIPE

d78c80d902 Clean up and comment C_UNTRACK 
Don't use it as a "cursor is tracked" hint in mdb_pages_xkeep().
It's been harmless so far, but would break after mdb_cursor_copy().
Checking m0 directly short-circuits better anyway.

72f875b48a Note functions which must set MDB_TXN_ERROR on failure 
Other functions depend on them to do so.
For mdb_node_read(), instead remove such a dependence.

a70200f15f Fix mdb_env_open() with MDB_VL32 
Init me_rpmutex independently of MDB_NOLOCK.
Plug leaks on mdb_env_open() failure.
Tweak mdb_env_close0() to handle the rearranged mdb_env_open().

67fb3c746a ITS#7992 Tighter utf8_to_utf16(), fix errcodes 
The 0xFFFD check seems due to misleading MultiByteToWideChar() doc.
Bad UTF-8 gives 0xFFFD in the output string, not the return value.

cdcf9da600 ITS#7682 F_NOCACHE: Allow error, skip any O_DIRECT 
We can run without F_NOCACHE if it fails. And we do not know
what combining it with O_DIRECT means, if a system has both.

45a88275d2 ITS#8489 reset cursor EOF flag in cursor_set

bypassed this step.
