bzrlib.repofmt.groupcompress_repo.GCCHKCanonicalizingPacker : API documentation

A packer that ensures inventories have canonical-form CHK maps.

Ideally this would be part of reconcile, but it's very slow and rarely needed. (It repairs repositories affected by https://bugs.launchpad.net/bzr/+bug/522637).

Method	__init__	Create a Packer.
Method	_exhaust_stream	Create and exhaust a stream, but don't insert it.
Method	_copy_inventory_texts	Copy the inventory texts to the new pack.
Method	_copy_chk_texts	Undocumented
Method	_get_filtered_canonicalizing_inv_stream	Filter the texts of inventories, regenerating CHKs to make sure they
Method	_use_pack	Override _use_pack to check for reconcile having changed content.

Inherited from GCCHKPacker:

Method	_get_progress_stream	Undocumented
Method	_get_filtered_inv_stream	Filter the texts of inventories, to find the chk pages.
Method	_get_chk_streams	Undocumented
Method	_build_vf	Build a VersionedFiles instance on top of this group of packs.
Method	_build_vfs	Build the source and target VersionedFiles.
Method	_copy_stream	Undocumented
Method	_copy_revision_texts	Copy revision data to the new pack.
Method	_get_chk_vfs_for_copy	Undocumented
Method	_copy_text_texts	Undocumented
Method	_copy_signature_texts	Undocumented
Method	_create_pack_from_packs	Undocumented

Inherited from Packer (via GCCHKPacker):

Method	pack	Create a new pack by reading data from other packs.
Method	open_pack	Open a pack for the pack we are creating.
Method	_log_copied_texts	Undocumented

def __init__(self, *args, **kwargs):

Create a Packer.

Parameters	pack_collection	A RepositoryPackCollection object where the new pack is being written to.
	packs	The packs to combine.
	suffix	The suffix to use on the temporary files for the pack.
	revision_ids	Revision ids to limit the pack to.
	reload_func	A function to call if a pack file/index goes missing. The side effect of calling this function should be to update self.packs. See also AggregateIndex

def _exhaust_stream(self, source_vf, keys, message, vf_to_stream, pb_offset):

Create and exhaust a stream, but don't insert it.

This is useful to get the side-effects of generating a stream.

def _copy_inventory_texts(self):

Copy the inventory texts to the new pack.

self._revision_keys is used to determine what inventories to copy.

Sets self._text_filter appropriately.
