[PATCH v3 00/11] fast export and import fixes and features

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is a series of small fixes and features for fast-export and
fast-import, mostly on the fast-export side.

Changes since v2 (full range-diff below):
  * Dropped the final patch; going to try to use Peff's suggestion of
    rev-list and diff-tree to get what I need instead
  * Inserted a new patch at the beginning to convert pre-existing sha1
    stuff to oid (rename sha1_to_hex() -> oid_to_hex(), rename
    anonymize_sha1() to anonymize_oid(), etc.)
  * Modified other patches in the series to add calls to oid_to_hex() rather
    than sha1_to_hex()

Elijah Newren (11):
  fast-export: convert sha1 to oid
  git-fast-import.txt: fix documentation for --quiet option
  git-fast-export.txt: clarify misleading documentation about rev-list
    args
  fast-export: use value from correct enum
  fast-export: avoid dying when filtering by paths and old tags exist
  fast-export: move commit rewriting logic into a function for reuse
  fast-export: when using paths, avoid corrupt stream with non-existent
    mark
  fast-export: ensure we export requested refs
  fast-export: add --reference-excluded-parents option
  fast-import: remove unmaintained duplicate documentation
  fast-export: add a --show-original-ids option to show original names
