Subject: [PATCH v5 00/15] reftable library
Date: Fri, 12 Mar 2021 20:19:41 +0000
Message-ID: <pull.847.v5.git.git.1615580397.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.847.v4.git.git.1607522429.gitgitgadget@gmail.com>

This splits the giant commit from
https://github.com/gitgitgadget/git/pull/539 into a series of smaller
commits, which build and have unittests.

The final commit should also be split up, but I want to wait until we have
consensus that the bottom commits look good.

version 12 Mar 2021:

 * tagged unions for reftable_log_record
 * some fixups by jun

Based on github.com/hanwen/reftable at
c33a40ad23dd622d8c72139c41a2be1cfa063e5f Add random suffix to table names

Han-Wen Nienhuys (14):
  init-db: set the_repository->hash_algo early on
  reftable: add LICENSE
  reftable: add error related functionality
  reftable: utility functions
  reftable: add blocksource, an abstraction for random access reads
  reftable: (de)serialization for the polymorphic record type.
  reftable: reading/writing blocks
  reftable: a generic binary tree implementation
  reftable: write reftable files
  reftable: read reftable files
  reftable: reftable file level tests
  reftable: rest of library
  Reftable support for git-core
  Add "test-tool dump-reftable" command.
