Phil Hord	5513deeade	Add a gzip indexing class for faster gz navigation ... The gzread function is slow. Every time you seek to a new location, the whole file up to that position has to be decompressed again. This causes massive lags when trying to do simple things in lnav on a large .gz file. Use the zlib inflate* functions instead and record the dictionary periodically while processing the file the first time. Then use inflateSetDictionary to restore the dictionary to a convenient location when trying to seek into the file again in the future. Use a default period of 1MB of compressed data for syncpoints. Each syncpoint uses 32KB. This is a ratio of 3.2%. For example, a 1GB .gz file (compressed size) will require us to keep 32MB of index data in memory. A better method may be to use a fixed number of syncpoints and divide the file appropriately. This would keep the memory bounded at the cost of slower file navigation on large .gz files. Use pread to read the data for the stream decompressor and remove the lock_hack previously employed. NB. The documentation on these zlib functions is sparse. I followed the example in zlib/examples/zran.c, but I used the z_stream total_in and total_out variables instead of keeping my own separately as zran.c does. Maybe this is incompatible with some very old zlib versions. I haven't looked.	5 years ago
