| | | | | We switched to using the fast decompress method that returns the number of bytes read, rather than the size of the decompressed chunk.

| | | | Once we have taken 20x the maximum page size, stop. This prevents pathological behavior in sythetic workloads where a page is forced out of cache, then compresses into a single page on disk, and we repeat for every update.

* Don't loop on calls to deflate until Z_OK isn't returned, we're not addingKeith Bostic2014-05-121-3/+3

* Remove decrement of the destination length by one, when setting up forKeith Bostic2014-05-121-1/+1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | buffer, deflateEnd will return Z_BUF_ERROR: From the docs (http://www.zlib.net/manual.html): deflate() returns Z_OK if some progress has been made (more input processed or more output produced), Z_STREAM_END if all input has been consumed and all output has been produced (only when flush is set to Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example if next_in or next_out was NULL), Z_BUF_ERROR if no progress is possible (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not fatal, and deflate() can be called again with more input and more output space to continue compressing. Also, I don't think there's any reason to loop around deflate calls when Z_FINISH is specified, I think deflate will return Z_OK the first time it's called, then return Z_BUF_ERROR the second time it's called, because no progress is possible. From the docs: If the parameter flush is set to Z_FINISH, pending input is processed, pending output is flushed and deflate returns with Z_STREAM_END if there was enough output space; if deflate returns with Z_OK, this function must be called again with Z_FINISH and more output space (updated avail_out) but no more input data, until it returns with Z_STREAM_END or an error. After deflate has returned Z_STREAM_END, the only possible operations on the stream are deflateReset or deflateEnd. Reference #1005.
