Attributes are unmaintained and unused.
They have become more of a liability than a benefit.
This change eliminates them from the codebase.
The only user-visible change (assuming that attrs are not used) is that the attrs field will no longer appear in row JSON.
There are subtle inconsistencies, like "01" being a valid decimal but not
a valid integer, which vaguely bug me. Cleaning this up, and the corresponding
parser logic.
A number can't have leading spaces because the grammar doesn't
put spaces in them in the first place, so stop accepting them in the
number syntax. This should never have any impact on anything,
it's just simpler.
Update a couple of test cases to reflect this -- no longer testing
that trailing spaces are okay, now testing that they're not, for
instance.
We still prohibit a space before a leading '(', which maybe we shouldn't,
but we now allow spaces on both sides of a closing ')' more consistently.
Drop the unneeded "sp" before "close" in the special handling after
null, true, and false, because close now implies that.
Also, refactored the two instances of "sp '=' sp" into a thing called eq,
which may not be worth it.
Use "" strings for fixed string names. In startCall(), look up the
lowercase conversion of a call name in a table mapping all-lowercase
representations to canonical case, so we don't have to chase down
everyplace in the rest of the code base that assumes "Row" is
capitalized exactly like that.
PQL always produces decimals, which have effectively-arbitrary range,
but can convert them to floats when required; the executor then requests
this conversion in the handful of cases (SetRowAttrs and SetColumnAttrs)
where it wants floats rather than decimals.
Not yet fixed: The "Range" call may also be wrong now. It was specifying
an "fvalue" but is now effectively getting what used to be called a
"dvalue". However, so far as I can tell, that didn't work before either.
Want to do some PQL cleanup. A new version of peg turns out to dramatically
alter performance in some cases, so I'm doing the commit for "don't change any
PQL, just change the version of peg" checkin separately.
This modifies the parser to properly "unquote" incoming strings. So if
a string comes in double or single quoted, we approximately follow Go
rules for removing the quotes and processing escape sequences.
The differences from Go are:
1. we only support backslash, quote, tab and newline escape
sequenences.
2. Single quoted strings are supported and work just like double
quoted strings.
3. The peg parser won't actually accept backquoted strings (I don't
think)
Fixes: #411
This commit introduces a new type: pql.Decimal
We use that instead of float64 in order to ensure
that the string representation is consistent.
One unfortunate discovery during implementation is
that the RowAttrs and ColAttrs support floats, and
the PEG file was treating them as such. So I had
to split the PEG definitions into float-specific
items and decimal-specific items.
This PR adds support for anti-entropy syncing for integer
and decimal fields. It differs from the logic for other
field types in that it does not rely on a consensus to determine
what the value should be; instead, it considers the correct
values to be those of the primary replica. From there, data
is pushed to all non-primary replicas.
had to workaround some cruft in the parser that was trying to only
support a BETWEEN query as LTE, LTE. Now we have operations for all
combinations of LT and LTE.
unrelated - changed the port a test was binding to as it conflicted
with a port I was using locally.
So with the switch to a new linter, we get a lot of new warnings,
and the majority of them are harmless probably, but a few might be
real. Variously just use _ to suppress warnings, or report errors.
There's probably things here that deserve better fixes, but we can
always revisit it.
