-archive/tar: fix writing of pax headers
-
-"archive/tar: reuse temporary buffer in writeHeader" introduced a
-change which was supposed to help lower the number of allocations from
-512 bytes for every call to writeHeader. This change broke the writing
-of PAX headers.
-
-writeHeader calls writePAXHeader and writePAXHeader calls writeHeader
-again. writeHeader will end up writing the PAX header twice.
-
-example broken header:
-PaxHeaders.4007/NetLock_Arany_=Class_Gold=_Ftanstvny.crt0000000000000000000000000000007112301216634021512 xustar0000000000000000
-PaxHeaders.4007/NetLock_Arany_=Class_Gold=_Ftanstvny.crt0000000000000000000000000000007112301216634021512 xustar0000000000000000
-
-example correct header:
-PaxHeaders.4290/NetLock_Arany_=Class_Gold=_Ftanstvny.crt0000000000000000000000000000007112301216634021516 xustar0000000000000000

-
-This commit adds a dedicated buffer for pax headers to the Writer
-struct. This change increases the size of the struct by 512 bytes, but
-allows tar/writer to avoid allocating 512 bytes for all written
-headers and it avoids allocating 512 more bytes for pax headers.

-archive/tar: reuse temporary buffer in readHeader
-
-A temporary 512 bytes buffer is allocated for every call to
-readHeader. This buffer isn't returned to the caller and it could
-be reused to lower the number of memory allocations.
-
-This CL improves it by using a pool and zeroing out the buffer before
-putting it back into the pool.
