2012-01-30tdb2: careful on wrap.Rusty Russell1-10/+19
It's much harder to wrap a 64-bit tdb2 than a 32-bit tdb1, but we should still take care against bugs. Also, we should *not* cast the length to a size_t when comparing it to the stat result, in case size_t is 32 bit.

2011-09-14tdb2: add error conversion functions.Rusty Russell1-4/+4
This clarifies the code a little, but also provides a more explicit mechanism which can be used to debug error handling (by introducing tdb_err_t and making it a pointer type). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit afa6d57b7d93fe4675a952f556eb462951baa257)
2011-09-14tdb2: unify tdb1_get_seqnum/tdb1_increment_seqnum into ↵Rusty Russell1-0/+5
tdb_get_seqnum/tdb_inc_seqnum Switch on the TDB_VERSION1 flag. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 57359c26e9626aa986ee0538efd13a44a466f39d)
2011-09-14tdb2: merge tdb1_context into tdb_context.Rusty Russell1-24/+24
Finally, we split out the tdb2-specific parts of tdb_context, and put them into a "tdb2" sub-struct; the tdb1 parts go into a "tdb1" sub-struct. We get rido of tdb1_context and use tdb_context everywhere. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit bbeb528e74c0e234e1f724ac8d54be404cfc6f9a)
2011-09-14tdb2: add TDB_RDONLY flag, allow setting/unsetting it.Rusty Russell1-5/+5
You can only unset it if the TDB was originally opened O_RDWR. Also, cleaned up error handling in tdb_allrecord_lock() so we only get one log message on a r/o database. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit b87e14495d5b07e1b247218a72329f10ecb3da7f)
2011-09-14tdb2: save open_flags instead of mmap_flags.Rusty Russell1-1/+8
It's more consistent with what tdb1 does, and slightly more encapsulated. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 6b7c3c840eafbec211b9f58751c5ff754302a68e)
2011-09-14tdb2: cleanup oob handling.Rusty Russell1-17/+21
The tdb_oob() function can fail due to errors, as well as because the length asked for is greater than the size of the file. Clean that up: (1) If probe is true, only fail if there's an error, not if the length is too great. (2) Exit tdb_open() if it tdb_oob() probe fails; this helps cut down test time for failtest. (3) Don't set probe to true in tdb_direct() fail; a minor issue, but it means we log failure.
