A pack is a compact representation of a bunch of objects, stored using deltas where possible. They have two parts, the pack file, which stores the data, and an index that tells you where the data is. To find an object you look in all of the index files 'til you find a match for the object name. You then use the pointer got from this as a pointer in to the corresponding packfile. ) defaultdictN)BytesIOUnsupportedOperation)deque)chain)sha1)SEEK_CURSEEK_END) unpack_fromTFPlan9)ApplyDeltaErrorChecksumMismatch)GitFile) LRUSizeCache)ShaFile hex_to_sha sha_to_hex object_header c/n[U5S:Xd USS-(a^U"S5nUb[R"X15nUR[ USS55 [U5S:XaMOUSS-(aM^X!4$)zJRead bytes marked with most significant bit.

Each object in the pack is guaranteed to be inflated exactly once, regardless of how many objects reference it as a delta base. As a result, memory usage is proportional to the length of the longest delta chain. Subclasses can override _result to define the result type of the iterator. By default, results are UnpackedObjects with the following members set: * offset * obj_type_num * obj_chunks * pack_type_num * delta_base (for delta types) * comp_chunks (if _include_comp is True) * decomp_chunks * decomp_len * crc32 (if _compute_crc32 is True) FNcXlX l[[5Ul[[5Ul/Ul0Ul/Ulgr+) r_resolve_ext_refrr _pending_ofs _pending_ref _full_ofs_shas _ext_refs)r/file_objrs r$r0DeltaChainIterator.__init__Is< /'-'- r&cU"SUS9nURU5 UR5HnURU5 M U$)Nr) set_pack_datarr)r pack_datarwalkerrts r$r DeltaChainIterator.for_pack_dataRs@T?;Y'!002H MM( #3 r&c@URnURnU[:Xa-X1R- nURUR U5 gU[ :Xa)URURR U5 gURR X245 gr+) r?r;rvr@r?rrwr@rA)r/rtr{r;rs r$rDeltaChainIterator.recordZs)) y  #6#66K   k * 1 1& 9  "   h11 2 9 9& A NN ! !6"4 5r&c&URUlgr+)r)r/rHs r$rG DeltaChainIterator.set_pack_dataes __ r&c## URH"upURXS5HnUv M M$ UR5HnUv M UR(aeg7fr+)rA _follow_chain_walk_ref_chainsr?)r/r;r{rs r$_walk_all_chains#DeltaChainIterator._walk_all_chainshs_ $ F,,VtD E!/++-FL.$$$$$sA"A$cUR(a/[URVs/sHn[U5PM sn5egs snfr+)r@rr)r/rfs r$_ensure_no_pending%DeltaChainIterator._ensure_no_pendingps9   43D3DE3DaJqM3DEF F EsAc## UR(dUR5 g[URR 55HupXR;aMURU5up4UR RU5 URRU5 UH nURXSU5HnUv M M" M UR5 g![ a Mf=f7fr+) r>rUrr@itemsrrCrpoprP)r/base_shapendingr{rp new_offsetrs r$rQ#DeltaChainIterator._walk_ref_chainsts$$  # # % !'(9(9(?(?(A!B H000 #'#8#8#B  NN ! !( +    ! !( +% "00vNF LO&"C !   s+AC4C#2A1C4# C1-C40C11C4cU$r+r7r/rts r$_resultDeltaChainIterator._resultsr&cNURRU5 [URRURUR S9upEXlUcURU:XdeU$UR[;deX$l [X4R5Ul U$)N)rury) rrrr! _include_comp_compute_crc32r;r?rEr=rrBr>)r/r;r= base_chunksrtrs r$_resolve_object"DeltaChainIterator._resolve_objects # JJOO++--  !  ))\9 99 ))[8 88$0 !"-k;Q;Q"RH r&c#`^# XU4/nUHupnURXU5mURT5v [URR TR /5UR R TR5/55nURU4SjU55 M g7f)Nc3V># UHnUTRTR4v M g7fr+)r=r>).0r\rts r$ 3DeltaChainIterator._follow_chain..s+"+JX22H4G4GH"+s&)) rfr`rr?rYr;r@rJr)r/r;r=rer unblockedrts @r$rP DeltaChainIterator._follow_chains{3415 -F+++F+NH,,x( (!!%%hoor:!!%%hllnb9I KK"+ 26sB+B.c"UR5$r+)rRrIs r$rDeltaChainIterator.__iter__s$$&&r&cUR$r+)rCrIs r$ext_refsDeltaChainIterator.ext_refss ~~r&)rCrrAr?r@r>rBr+)r2r3r4r5rjrdrcr0r:rrrGrRrUrQr`rfrPrrrr6r7r&r$r<r<1s_(NM 6%%G".
