These exist because TAME is nondeterministic, so all state must be passed
into it. But it's inconvenient to have users have to manually fill in
dates, so we derive them from the environment unless they are set.
* src/current/scripts/entry-form.js (fillTimeValues): New function.
(rater): Use it.
csvm2csv was not failing when csvm-expand exited with a non-zero
status. Further, the tests were written incorrectly to account for this.
* build-aux/csvm2csv: Set `pipefail' option.
* build-aux/test/test-csvm2csv: Fix tests.
While tabs aren't desirable, users that are not developers will be modifying
these files, and so we need to be permissive in what we want to
accept. That doesn't mean that we need to forego occasional formatting, though.
tamed was originally designed with support for parallel builds in mind, but
I hadn't completed that work because we didn't have enough hardware that
we'd benefit strongly from it. That has since changed.
tamed will now spawn additional runners as needed to fulfill requests, which
works around the issue of not knowing how many jobs GNU Make is going to try
to do at once.
There were a couple minor dependency fixes/workarounds for now in the
Makefile, but otherwise everything appears to be working great.
A table with a couple hundred thousand rows was taking minutes to
generate. This gets it down to a few seconds.
* build-aux/csvm-expand (parse_date): New function.
(parseline): use it.
This aims to prevent needlessly wasted time debugging a non-working test
case, and to avoid writing incorrect test cases that happen to succeed even
though their inputs aren't properly defined.
For example, a common error is to use the name of a bucket field rather than
the name of the param that it maps to.
* progtest/src/TestRunner.js (_verifyKnownParams): New method.
(_tryRun): Use it.
* progtest/test/TestRunnerTest.js: New test case. Modify existing test
cases to define used params.
* progtest/test/_stub/program.js (exports.rater.params): Declare used param.
This reduces overall build times for one of our systems by ~50% by
addressing a lot of the low-hanging fruit for compilation of object
files. There is much more work to be done, and the addition of maps added a
little bit of a mess that will be abstracted in future commits once I'm done
surveying the possible improvements that can be done.
This further improves performance of the symbol table processing. The next
step will be to address how symbols are handled on a more intimate level,
since it's a huge mess atm. But I'll save that for later, after the
low-hanging fruit has been resolved.
* src/current/include/preproc/symtable.xsl (preproc:sym-discover): Use
`for-each-group' in place of `preceding-sibling'. Aggressive use of
maps for geneating the `dedup' sequence, which is a mess.
(preproc:symtable-process-symbols): Additional maps to avoid
preceding-sibling and following-sibling selectors (O(n²)=>O(n)).
Same concept as previous commits: rather than iterating over the symbol
table and scanning the tree for the matching node, iterate over the document
and look up from a symbol map: O(n²) => O(n).
This gives a respectable performance boost to compilation of certain
packages (best improving packages with many classifications or rate blocks).
* src/current/compiler/fragments.xsl (@xmlns:xs, @xmlns:map): New namespace
declarations.
(preproc:compile-fragments): Generate `preproc:fragment' nodes and match
on document rather than symbols.
[lv:package]: Generate map and tunnel it.
* src/current/compiler/js.xsl (compile)[lv:classify, lv:match]: Use
symtable-map.
(compile-class-condition)[lv:rate]: Likewise.
(compile-cmatch)[lv:rate]: Likewise.
This uses the same map strategy (and same duplicate code) as previous
commits, but this one generates a map for two separate tables.
There is more room for improvement, but this cuts down on the time a
lot. Also keep in mind that this is performed multiple times (once per
pass), so it's still worth revisiting. Performance is still very poor for
very large (many thousands of symbols) symbol tables.
The next slowest part appears to be the fragment compilation. I'm nearing
the end of the low-low-hanging fruit for maps. The /common/gl package
mentioned in previous commits that previously took over a minute to compile
now compiles in 20s as of this commit on equivalent hardware.
* src/current/include/preproc/symtable.xsl (@xmlns:map): New namespace
declaration.
(preproc:symtable-process-symbols): Create map for `cursym' and
`extresults'. Use it. Remove unused `dup'. Output message when
done (another is output slightly later on in the process).
This is the first step to improving the map. Note that this duplicates the
symbol table generation code that's used in a few other places
now---that'll be cleaned up in future commits once I have a better idea of
all the places this will be used and try to move it to a higher level.
* src/current/compiler/validate.xsl (@xmlns:xs, @xmlns:map): New namespace
definitions.
(lvv:validate)[lv:package]: Generate symbol table map. Tunnel to
templates.
[c:apply[@name], lv:classify[@as]//lv:match, lv:match[@value]]
[c:*[@name or @of], c:apply/c:arg[@name], lv:rate/lv:class]: Use it.
The existing code was not only complex (because of XSLT 1), but mostly
unnecessary. We don't need to consult remote symbol tables at all anymore.
This shaves off an additional few seconds on large packages.
* src/current/include/preproc/package.xsl (preproc:resolv-syms)[preproc:sym]:
Only consult local symbol table. Simplify max dimension calculation.
This is a first step (low-hanging-fruit kinda thing) for improving the
performance of symbol resolution, where the compiler has to figure out the
dimensions of a symbol by first resolving its dependencies,
recursively. This is approximately an O(n³) polynomial-time algorithm _per
recursive step_. Yikes.
This is traditionally where dynamic programming methods would be used, but
that's considerably more difficult in a immutable languages like XSLT, so
I'll do my best without. (Saxon does offer some support for mutability, but
I'd prefer to avoid it if possible.)
This first change improves performance 30--40%. For example, on two large
packages we have, build times drop from 55s to 35s and from 1m42s to 1m13s
respectively.
Good start, but much more to be done!
* src/current/include/preproc/package.xsl (preproc:resolv-syms)[lv:package]:
Compute maps for preproc:symtable and preproc:sym-deps at each recursive
step. Pass along via tunneling.
(preproc:resolv-syms)[preproc:sym]: Use them.
DEV-4354
This only saves 1--2s on a 30s run, but I want to move into this direction,
so it'll simplify future refactoring if I just add it. Small changes like
these will accumulate, too.
* src/current/compiler/linker.xsl (l:orig-package, l:root-symtable-map): New
variables.
(l:resov-extern): Use it.
A bunch of failing pipelines apparently wasn't obvious to me. And shame on
me for not running these locally; I forgot that the part of the system that
I touched had tests.
This was broken by b6cfdb4221.
This now uses year ranges, which I'll update annually.
This also renames "R-T Specialty" to "Ryan Specialty Group". The latter is
the parent company of the former. I was originally employed under the
former when LoVullo Associates was purchased, by I now work for the parent
company.
The previous commit made dependency lists optional for certain symbols. The
Summary Page needs to be updated to permit such a thing.
The whole Summary Page needs aggressive refactoring, though, so this doesn't
bother checking for `no-deps' to see if this is a bad thing.
* src/current/summary.xsl (typeset-final)[preproc:sym-ref]: Permit missing
symbol dependencies.
(lv:param|lv:const|lv:item): Likewise.
This is a significant performance improvement for dependency
generation (which is responsible for building the dependency graph for a
package).
The previous algorithm ran in O(n²) time: it would iterate over the given
symbol table, and for _each_ symbol, do a linear scan of the entire document
to search for the corresponding source block. This resulted in explosive
depgen time for larger packages.
This makes the algorithm run in O(n) by:
- Using an XSLT 3 map for the symbol table for O(1) lookups; and
- Iterating over the _document_ a single time rather than the symbol
table, referencing the symbol table as needed (in O(1) time).
There are other parts of the system that can benefit from these same
improvements. This is important, since we need to be able to handle many
thousands of symbols efficiently.
* src/current/compiler/linker.xsl (l:depgen-sym): Recognize smybol `no-deps'
property, permitting missing dependencies. This allows us to avoid
creating nonsense nodes just to satisfy the linker, while still allowing
the linker to perform essential checks to defend against compiler bugs.
* src/current/compiler/map.xsl (lvmc:stub-symtable): Set @no-deps on
`___head' and `___tail' symbols.
(lvmc:mapsym): Set `no-deps' as appropriate on map symbols.
(preproc:depgen)[lvm:map[@from]]: Generate `preproc:sym-dep' node, which
is now expected by the depgen process.
(preproc:depgen)[lvm:map[*]]: Likewise.
(preproc:depgen)[*[@lvmc:type='retmap']//lvmm:map[@from]]: Remove
unnecessary template.
(preproc:symtable)[lvm:map[@value]]: Pass `no-deps' to `lvmc:mapsym'.
* src/current/include/depgen.xsl (preproc:depgen)[preproc:symtable]: Create
and use XSLT 3 map in place of `preproc:symtable' tree. This allows for
constant-time lookups. Provide to templates via tunnelling. Use it in
place of exiting tree references. Process source tree rather than
iterating over symbol table.
(preproc:depgen)[lv:rate, c:sum[@generates], c:product[@generates],
lv:classify, lv:function/lv:param, lv:function, lv:typedef]: Produce
`preproc:sym-dep' nodes (which was previously done while iterating
over the symbol table).
(preproc:depgen)[preproc:sym]: Remove all such processing, since we no
longer iterate over the symbol table.
(preproc:depgen)[c:value-of]: Use symtable map.
(preproc:depgen-match): Likewise.
(preproc:depgen)[lv:union]: Modify to handle changes to lv:typedef
template.
(preproc:depgen)[text()]: Remove and replace with `node()'.
* src/current/include/preproc/package.xsl (preproc:resolv-syms): Remove
logging of symbol resolution. This has a slight performace impact since
there is a lot of output.
* src/current/include/preproc/symtable.xsl
(lv:function/lv:param, c:let/c:Values/c:value): Set `no-deps'.
* src/symtable/symbols.xsl: Add documentation of `no-deps'.
(preproc:symtable)[lv:meta]: Set `no-deps'.
These provide a more pleasent abstraction than having to reference CMP_OP_*
constants.
* core/test/core/vector/interpolate.xml: {t:when=>t:where-eq}.
* core/test/core/vector/table.xml: Likewise, but using the other variants
where appropriate given the value of `@op'.
* core/vector/interpolate.xml: Likewise.
* core/vector/table.xml (_when_, _where_): Rename former to latter and
provide deprecation warning.
(_when-lt_, _when-lte_, _when-gt_, _when-gte_): Add abstractions.
* src/current/rater.xsd: Permit template variable as tenplate name.
This is fairly primitive support and it completely sidesteps the bisect
algorithm for now. The next commit will abstract this a little bit further
to make it less awkward to use.
* core/test/core/vector/table.xml: New test cases.
* core/vector/filter.xml (CmpOp): New typedef.
(mfilter): Document that bisecting will not happen unless `CMP_OP_EQ'
is used. Implement that restriction.
[op]: New parameter. Provide it to `mrange'.
(_mfilter, _mrange_cmp): Rename from `_mfilter'. Implement new comparison
check based on `op'
[op]: New argument.
* core/vector/table.xml (_when_)[@op@]: New param. Add it to the produced
vector.
(_mquery): Unpack op (from `_when_') in call to `mfilter'.
Just trying to clean up a little as I go to start to make it easier
to understand.
* core/vector/filter.xml: Use _when-*_ templates and c:recurse.
* core/vector/table.xml: Likewise.
It's going to be like TeX before you know it... ._.
* src/current/include/preproc/package.xsl (preproc:tpl-check)
[lv:template|lv:const|lv:typedef|lv:param-copy]: Add lv:param-copy.
* src/current/include/preproc/template.xsl (preproc:apply-template)
[lv:expand-barrier, lv:skip-child-expansion]: New expansion control
structures.
This is a much more useful description if present.
* src/current/include/preproc/macros.xsl (preproc:macros)[c:value-of...]:
Default generated constant description to @label.
The term "set" is all wrong---it is actally intended to be a vector, and can
absolutely have duplicate elements (and often does).
* src/current/calc.xsd (vector): Add, recommending in place of `set'.
* src/current/compiler/js-calc.xsl (compile-calc)[c:set|c:vector]:
Add `c:vector' and provide deprecation notice for `c:set'.
* src/current/include/calc-display.xsl (c:set|c:vector): Likewise.
* core/test/spec.xml (_describe_): Enclose aggregate classification in a
series of nested expand-sequence to work around bug (described in
comment), which was causing test cases to not be compiled.
A better option is to pre-process all inputs, but I need a quick
fix to my stupidity. 0||""==="".
* src/current/compiler/map.xsl (lvmc:compile)[lvm:map//lvm:from[*]]: Correct oval default.
I wanted to get this section started so that I can easily add to it when I
have small bits of time to do so. Our documentation needs to improve.
* doc/Makefile.am (tame_TEXINFOS): Add `concept.texi'.
* doc/concept.texi: New file.
* doc/preproc.texi: Remove accidentally added input line.
* doc/tame.texi (menu): Add `Core Concepts' node.
I need to revert this for now because it breaks YAML test cases. The proper
fix is a more expressive type system with dependent types that would allow
it to know the proper number of indexes to initialize relative to other
inputs. I wanted to implement this anyway to help catch iteration-related
bugs.
I'm tabling this for now, though, since I have other things that I need to
work on.
This reverts commit 4406cbe553.
This includes, notably, the Developer Notes feature. I did not copy any
SRCUI stuff since this project uses literate documentation, but I'll add it
if it seems like it will be useful. Barely any of the project is written
literately right now.
* .gitignore: `{=>/}config.*'.
* configure.ac (SET_DEVNOTES): New variable.
(AC_CONFIG_FILES): Add `doc/config.texi'.
* doc/.gitignore (config.texi): Ignore (generated).
* doc/Makefile.am (tame_TEXINFOS): Add `macros.texi' and `config.texi'.
* doc/config.texi.in: New file.
* doc/macros.texi: New file containing some macros from `doc/tame.texi' and
some from Liza's `doc/macros.texi'.
* doc/tame.texi: Adjust position of header comment. Include `config.texi'
and `macros.texi'. Add devnotice to header. Strip out macros.
(menu): Add `Concept Index' and conditional `Developer Notes Index'.
(Concept Index, Developer Notes Index): New nodes (latter conditional).
