121. By Wim Lewis on 2013-03-12

Avoid a gratuitous cast to uint64_t and back.

120. By Wim Lewis on 2013-03-12

The protocol allows fields as large as 2^64 bytes, so use a uint64_t to store field sizes and offsets within fields. Added some documentation for drizzle_field_read() and drizzle_field_buffer().

119. By Wim Lewis on 2013-03-12

It's possible to have more than 1024 (256*8) columns, so null_bitmap_length has to be larger than a uint8_t.

118. By Wim Lewis on 2013-03-11

The amount of data in param->data can technically be more than 2^32; it's limited by the size of our memory, so param->length should be a size_t.

117. By Wim Lewis on 2013-03-11

Avoid an unnecessary type cast to size_t.
Avoid a use-after-free of row_list if we have a realloc failure while reading a large result set.

116. By Wim Lewis on 2013-03-11

Avoid dereferencing pointers we know are NULL.

115. By Wim Lewis on 2013-03-11

Fixed a pair of typos in error messages.

114. By Wim Lewis on 2013-03-07

Fix fragmentary-field-reading logic in drizzle_state_field_read()
so that it doesn't accidentally cross a packet boundary.
Adjusted types of some field variables to match the largest values that
can be stored in them.

113. By Wim Lewis on 2013-03-06

Cast the result of crc32() to uint32_t.
zlib.h declares it as uLong, which is 64 bits on some machines.

112. By Wim Lewis on 2013-03-06

drizzle_unpack_string() integer-width safety.
The size of a buffer in our memory space is a 'size_t'.
Fail if the string extends past the limits of the buffer we're reading it from (should only happen if there's a protocol error).
