1.4.4

THE PROBLEM:

    ftruncate() creates "sparse files" - file size is set but disk space isn't allocated
    When database accesses memory-mapped sparse regions under disk pressure, SIGBUS occurs
    This causes unexpected database crashes in production environments

THE SOLUTION:

    fallocate() ensures real disk space allocation upfront
    Database operations either succeed completely or fail gracefully during initialization
    No surprise SIGBUS crashes during normal database operations

1.5.2

1. Some compilation fix in header when using newer gcc
2. Construct bound key in FindLower API

1.4.3

1. Fix compilation warning from newer gcc
2. Reconstruct key in FindLower

1.4.2

Fix shared pointer cleanup order issue in process exit

1.5.1

Fix build issue in ubuntu 24.04

1.5.0

1. Add jemalloc hooks for shared memory management; All entries in the DB will be cleared while process is restarted since jemalloc needs to be re-initialized. No need to use defragmentation is runnning in jemalloc mode. To use the feature, set the jemalloc bit mask, options |= mabain::CONSTS::OPTION_JEMALLOC.
2. Add cmake support for building

1.5.0-pre

1. Add jemalloc hooks for shared memory management
2. Add cmake support for building

1.4.1

Remove the old way of doing prefix match. Instead, the prefix match can be performed using iterator.

for(DB::iterator iter = db.begin(prefix); iter != db.end(); ++iter) {
     std::cout << iter.key << "\n";
}

Add RemoveAsync API

1.4.0

• Increase the value size from 1024 bytes to 32KB
• Reformat code to WebKit style
• Suppress some info to debug

Mabain 1.3.3
