Gabriel Wicke d918fa18ac Big token transform framework overhaul part 2
* Tokens are now immutable. The progress of transformations is tracked on
  chunks instead of tokens. Tokenizer output is cached and can be directly
  returned without a need for cloning. Transforms are required to clone or
  newly create tokens they are modifying.

* Expansions per chunk are now shared between equivalent frames via a cache
  stored on the chunk itself. Equivalence of frames is not yet ideal though,
  as right now a hash tree of *unexpanded* arguments is used. This should be
  switched to a hash of the fully expanded local parameters instead.

* There is now a vastly improved maybeSyncReturn wrapper for async transforms
  that either forwards processing to the iterative transformTokens if the
  current transform is still ongoing, or manages a recursive transformation if
  needed.

* Parameters for parser functions are now wrapped in abstract Params and
  ParserValue objects, which support some handy on-demand *value* expansions.
  Keys are always expanded. Parser functions are converted to use these
  interfaces, and now properly expand their values in the correct frame.
  Making this expansion lazier is certainly possible, but would complicate
  transformTokens and other token-handling machinery. Need to investigate if
  it would really be worth it. Dead branch elimination is certainly a bigger
  win overall.

* Complex recursive asynchronous expansions should now be closer to correct
  for both the iterative (transformTokens) and recursive (maybeSyncReturn
  after transformTokens has returned) code paths.

* Performance degraded slightly. There are no micro-optimizations done yet
  and the shared expansion cache still has a low hit rate. The progress
  tracking on chunks is not yet perfect, so there are likely a lot of unneeded
  re-expansions that can be easily eliminated. There is also more debug
  tracing right now. Obama currently expands in 54 seconds on my laptop.

Gabriel Wicke c688b039de Collected tweaks
* less verbose logging in noinclude processing and template expansion
* Give priority to the processing of templates transcluded from transclusions
  to get closer to depth-first processing. This serves to minimize memory
  usage from queued-up tokens.
* Increase the maximum outstanding requests per template retrieval. 10000
  amazingly proved too low a limit on some big pages.
* Only process a single template request callback at a time for now
* Add a debug print in the treebuilder wrapper
* Don't treat multiple comments on a single line as a single comment to match
  the PHP parser's behavior

Gabriel Wicke 5bb2d96869 Token stream transform improvements
* add past paths for empty arguments etc
* cache attribute token transform pipelines
* fix bugs in TokenCollector and NoIncludeOnly handler, and improve its
  efficiency by only registering for 'end' tokens on demand
* Remove empty reset methods from a few handlers
* Add a simple 'ap' debug print function that makes it easy to only print some
  debug prints by temporarily changing 'dp' to 'ap'
* Improvements and bug fixes in AttributeExpander

Gabriel Wicke 9ae572cca0 Fixes to template expansion / token transform managers, 296 tests passing.
* Convert isNoInclude logic to positive isInclude throughout and set it
  properly on attribute pipelines. Also don't cache non-include pipelines.
* Add a --pagename parameter to parse.js, which sets the page name in the
  environment. This is then returned by {{PAGENAME}}. Not the final solution,
  but useful for taxobox testing as taxons are selected based on PAGENAME.
* Add rudimentary pagenamebase parser function

Gabriel Wicke f02ff95aa3 Token representation clean-up. Now all tokens are differentiated using
constructors instead of type attributes.

Gabriel Wicke b8bb503199 Actually commit onlyinclude, as already announced in r112592. 2012-02-28 13:24:35 +00:00
Gabriel Wicke a122e51eec Move data-* annotations into separate object on tokens, that is then
serialized into a single data-mw-rt attribute if present. Update parserTests
to ignore this attribute for comparisons with expected parser output.

A few more tweaks and notes are thrown into this commit too. 233 tests are
passing now.

Gabriel Wicke 14a8a13678 A few more debug helpers including a --trace mode for light debugging. Some
improvements to parser functions on the way to support the cite extensions.
Preparation for generic template and template arg in attribute support. 222
parser tests now passing.
