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.
This is a kluge until time can be spent better factoring this
system (using Traits).
* src/bucket/StagingBucket.js (_noStagingBypass): Add field.
(forbidBypass): Add method to set field.
(setCommittedValues): Use field.
Copyright notices updated. More casual references to "LoVullo
Associates" replaced with "RT Specialty / Lovullo", which will be "RT
Specialty Buffalo" in the future. Or "RT Specialty", depending on how
this is rolled out. Or "Ryan Specialty Group". Who knows.
"R-T Specialty, LLC." is the legal name, which includes the dash. Not
to be confused with a certain television network.
I have sat on releasing a lot of this code for years because I wanted
the liza repo to be in a pristine state---tests and all---which
required a great deal of refactoring. Well, that never happened, and
time is up.
LoVullo Associates---my employer---has been purchased by another
company. This means that any agreement with LoVullo regarding
releasing free software is going to have to be re-negotiated with this
new company, and I have no idea how those negotiations will go. So,
I have no choice but to simply release everything in its current state,
or risk it being lost forever.
This represents work over the past 6--7 years, 99.9% of it written by
me. This project has been my baby for quite some time, and has been
through a number of battles with deadlines and other unfortunate
circumstances; the scars show. I also didn't really "know" JS when
starting this project. Perhaps you can help improve upon it.
There are some odds-and-ends that could be committed. And references
to insurance and LoVullo need to be removed to generalize this.
I hope that this will not be the last public commit for this project.
I'll fight the good fight and we'll see where that takes us. Maybe
it'll be easy.
Happy hacking.
This fixes accidental global variables and enables strict mode to
prevent it in the future.
* src/bucket/StagingBucket.js: Enable strict mode. Use const/let where
appropriate instead of var.
Since changes trigger any event observers---which can be
expensive---it is ideal to ignore sets that do not result in any
changes to the bucket.
This also resolves issues with systems that are confused by empty
diffs.
* src/bucket/StagingBucket.js
(_hasChanged): Add method.
(setValues): Use it.
* test/bucket/StagingBucketTest.js: Add test case.
