This mixes in support for non-terminating nulls. It would have been
nice to handle that in a separate commit for clarity, but the
refactoring came as a consequence of trying to provide a working
implementation.
Various inconsistencies and subtle bugs in unlikely situations have
been fixed by this, including modifying objects passed as arguments to
various methods, and inconsistent handling of diff data.
Changes are more consistently recognized. Perhaps the most noticeable
consequence is that moving between steps no longer prompts to discard
changes---previously calculated values would trigger the dirty flag on
steps even if the user didn't actually change anything. I (and
others) have wanted this fixed for many years.
This is a very dense commit that touches a core part of the
system. Hopefully the Changelog below helps.
* src/bucket/Bucket.js
(setValues): [BC-BREAK] Remove parameters `merge_index' and
`merge_null' parameters.
* src/bucket/DelayedStagingBucket.js
(setValues): [BC-BREAK] Remove `merge_index' and `merge_null
parameters. Remove distinction between `merge_index' and non-.
* src/bucket/QuoteDataBucket.js
(setValues): [BC-BREAK] Remove `merge_index' and `merge_null
parameters. Remove respective arguments from `_mergeData' call.
(_mergeData): Remove same parameters. Remove handling of
`merge_index' and `merge_null'.
(overwriteValues): Append `null' to each vector.
* src/bucket/StagingBucket.js
(_initState): Use `Object.create' instead of explicit prototype
instantiation (functionally equivalent).
(merge): Minor comment correction.
(_hasChanged): Rename to `_parseChanges'.
(_parseChanges): Rename from `_hasChanged'. Remove `merge_index'
parameter. Generate new object rather than mutation original
data (prevent dangerous and subtle bugs from side-effects). Clone
each vector rather than modifying/referencing directly (this was
previously done during merge). Remove `merge_index'
distinction. Handle non-terminating `null' values.
(setValues): [BC-BREAK] Remove `merge_index' and `merge_null'
parameters. Use new object generated by `_parseChanges'. Remove
cloning of each vector (`_parseChanges' now does that). Remove
`merge_index' distinction.
(overwriteValues): Remove argument to `setValues' call.
(getFilledDiff): [BC-BREAK] Use `_staged' rather than `_curdata'.
(commit): Remove second and third arguments of call to `setValues'
of underlying bucket.
* src/client/Client.js
(_initStepUi): Remove second argument of calls to quote `setData'.
* src/client/quote/ClientQuote.js
(setData): [BC-BREAK] Remove `merge_nulls' parameter. Remove second
and third arguments of call to staging bucket `setValues'. Add
comment indicating a long-standing problem with committing the
staging bucket contents before save has succeeded.
* src/server/request/DataProcessor.js
(processDiff): Remove `permit_null' argument of `sanitizeDiff'
call.
(sanitizeDiff): Remove `permit_null' parameter. Hard-code filter
call's `permit_null' argument to `true'.
(_determineDapiFields): Properly handle `null's (ignore) rather than
inadvertently converting them into the string "null".
* test/bucket/StagingBucketTest.js: Modify test cases
accordingly. Add tests to verify that updates and diffs operate
as expected, especially support for non-terminating `null's.
(createStubBucket): Use `QuoteDataBucket'. Ideally remove this
coupling in the future, but this is a more realistic test case for
the time being.
* test/server/request/DataProcessorTest.js: Update test to account for
hard-coded `given_null' argument.
