889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	517
24844 cf5928fab108 This is my patch Michael W. Hudson <mwh@python.net> parents: 24818 diff changeset	518 c_lnotab is an array of unsigned bytes disguised as a Python string. Since
cf5928fab108 This is my patch Michael W. Hudson <mwh@python.net> parents: 24818 diff changeset	519 version 2.3, SET_LINENO opcodes are never generated and bytecode offsets are
cf5928fab108 This is my patch Michael W. Hudson <mwh@python.net> parents: 24818 diff changeset	520 mapped to source code line #s via c_lnotab instead.
cf5928fab108 This is my patch Michael W. Hudson <mwh@python.net> parents: 24818 diff changeset	521
18065 889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	522 The array is conceptually a list of
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	523 (bytecode offset increment, line number increment)
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	524 pairs. The details are important and delicate, best illustrated by example:
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	525
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	526 byte code offset source code line number

889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	533 The first trick is that these numbers aren't stored, only the increments
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	534 from one row to the next (this doesn't really work, but it's a start):

889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	538 The second trick is that an unsigned byte can't hold negative values, or
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	539 values larger than 255, so (a) there's a deep assumption that byte code
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	540 offsets and their corresponding line #s both increase monotonically, and (b)
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	541 if at least one column jumps by more than 255 from one row to the next, more
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	542 than one pair is written to the table. In case #b, there's no way to know
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	543 from looking at the table later how many were written. That's the delicate
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	544 part. A user of c_lnotab desiring to find the source line number

889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	553
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	554 In order for this to work, when the addr field increments by more than 255,
889db6d55506 SF bug 430991: wrong co_lnotab Tim Peters <tim.peters@gmail.com> parents: 17736 diff changeset	555 the line # increment in each pair generated must be 0 until the remaining addr
