Extended the Unique-type cleanup checks ([74e71fae100d44]) to Tuples, which hypothetically have the same cleanup error case (but it's never been witnessed). Edit: and accidentally checked in unrelated termbox tinkering at the same time :/. file: [2e0b9129e8] check-in: [eae27e464a] user: stephan branch: trunk, size: 483921)
13:40
cwal core now gc-queues all values (not just containers) during scope cleanup. This fixes a difficult-to-trigger cleanup-time problem involving Unique-type values and their non-container wrapped values. file: [8934a4a74c] check-in: [74e71fae10] user: stephan branch: trunk, size: 481338)
2018-01-03
16:04
consistency: changed signature of cwal_prop_has() and cwal_prop_has_v(), removed cwal_prop_has_s(). file: [0200054e04] check-in: [db1a5c3526] user: stephan branch: trunk, size: 480520)

removed some dead code. file: [fcc7438c4e] check-in: [0be8130cf2] user: stephan branch: trunk, size: 487648)
11:30
Minor refactoring in the scope of interceptor support. Changed the cwal-internal string hash routine again. Added some metrics output. file: [54fbd62e38] check-in: [47e9b8e8a6] user: stephan branch: trunk, size: 488671)
10:10
Fixed some ref/unref boneheadedness in cwal_json which prematurely killed values (bug introduced in [ad93dd9b93e37763]). Added missing ref/unhand in cwal_scope_pop2() which killed propagating values. file: [05435a3424] check-in: [957e87d7f8] user: stephan branch: trunk, size: 487181)

minor tweak to the string is-ascii determination. file: [84f2296458] check-in: [817bebac7a] user: stephan branch: trunk, size: 481563)
2017-12-08

Minor proactive rescoping fixes. file: [212d07decf] check-in: [6848b566bc] user: stephan branch: trunk, size: 480698)
2017-12-06
19:13
Apparently fixed an old bug in cwal_prop_get_kvp(). A slight semantics change to cwal_kvp_flags_set(). Tweaks to how cwal_function_call_in_scope() handles references. Fixed an old missing result code check which somehow never caused grief (or did it?). file: [bed819cb5d] check-in: [e491db6af4] user: stephan branch: trunk, size: 480550)
2017-12-03
21:09
Tiny random cleanups. file: [23890ef119] check-in: [ed33242e31] user: stephan branch: trunk, size: 480709)
15:16
Added cwal_build_info() to make various build-time config options available to client code. Stole another bit from the maximum string length to add an is-ascii flag to strings, which we can use to speed up many algorithms for the most common cases (but it slows down string creation for the common case). file: [a290ef81d3] check-in: [72236d95aa] user: stephan branch: trunk, size: 480709)
2017-12-02
14:33
Made the range of built-in integers build-time configurable and removed the shared-instance integer cwal_weak_refs. Removed some cruft from CWAL_BUILTIN_VALS. file: [1f8410ec99] check-in: [79988ded9c] user: stephan branch: trunk, size: 475325)
2017-12-01
19:26
Added cwal_engine_outputer_get/set() to simplify swapping out the outputer. Added cwal_output_f_cwal_outputer(). file: [5a3982e9ba] check-in: [2a21245d11] user: stephan branch: trunk, size: 475160)
2017-11-30
18:32
a minor const correctness fix in cwal_unique_wrapped_get(). file: [a9b4f29890] check-in: [38620308fe] user: stephan branch: trunk, size: 474543)
2017-11-21
17:05
added a reminder to self. file: [a552b2c671] check-in: [35baac6ef3] user: stephan branch: trunk, size: 474537)
15:57
Fixed the length-1 string handling for X- and Z-strings. file: [16cc18f176] check-in: [717abf2614] user: stephan branch: trunk, size: 474347)
12:43
cwal core now includes all byte-length-1 ASCII strings in its builtin Values. In the various s2 unit tests this cuts alloc counts by anywhere from ~1% to ~12% with recycling disabled and ~1% to ~2.5% with recycling enabled. Total memory use without recycling was cut by ~1-10% and is highly script-dependent (those with many length-1 variable names save more). file: [8ed4bb8a13] check-in: [8bef0b5c74] user: stephan branch: trunk, size: 473234)
2017-11-13
12:26
minor utility API renaming and additions. file: [23a10e314e] check-in: [d8df88227b] user: stephan branch: trunk, size: 471272)
09:38
Moved ownership of s2's eval-holder array from the eval() routine to s2_scope. This cuts allocations drastically when recycling is disabled, reducing the unit test amalgamation alloc counts by about 1/3rd and saving 1M of total alloc'd memory. The savings when recycling is on are minimal but better than nothing. file: [19db9c811a] check-in: [61f4780ed8] user: stephan branch: trunk, size: 470659)
07:08
Refactored s2's various assignment operators for better ref/unref handling and readability. file: [fb218738fa] check-in: [557510fcb9] user: stephan branch: trunk, size: 470666)
2017-11-12
10:49
Discovered and applied gcc's -Wextra warning level, plus patched up violations it caught (mostly missing struct member initializers). file: [eafec55b8c] check-in: [f13f6c3c4b] user: stephan branch: trunk, size: 470672)
09:06
Migrated s2.Buffer.replace() implementations into core cwal functions. file: [e500a18593] check-in: [e980d01913] user: stephan branch: trunk, size: 470640)
2017-11-10
20:49
cwal_value_from_arg() now trims starting/ending quotes from the value part of --key="value". file: [3ae29f2b97] check-in: [f37e0dbf88] user: stephan branch: trunk, size: 467856)
2017-11-07
13:10
reworked the change to cwal_buffer_fill_from_filename() from the previous commit. file: [c10c2c104f] check-in: [673581aadb] user: stephan branch: trunk, size: 467685)
13:06
imported GLOB/LIKE pattern matching from sqlite3. Added s2.glob(glob,haystack[,globStyle]). file: [19458a8bb5] check-in: [4eac2f17a9] user: stephan branch: trunk, size: 467683)
2017-11-03
11:49
Minor semantics change in cwal_exception_setfv() and friends (returning CWAL_RC_OOM as-is, rather than trying to create an exception object). file: [0ef9e8c0a3] check-in: [5e957a91c3] user: stephan branch: trunk, size: 467792)
00:59
minor doc tweaks file: [a09efda190] check-in: [38b67c092e] user: stephan branch: trunk, size: 467508)
2017-10-13
12:36
minor (and arguable) CWAL_TYPE_LISTMEM metrics tweak: no longer count a cwal_list_reserve() of a larger size as an alloc request if we already have enough memory in the list. file: [a0650e6dc3] check-in: [29f0e06050] user: stephan branch: trunk, size: 467410)
12:23
s/\bUNUSED\b/CWAL_UNUSED_VAR/g. Minor s2 unit test tweak. file: [a616f4ddcb] check-in: [6eaa08f972] user: stephan branch: trunk, size: 467415)
2017-10-12
12:11
Random tiny cleanups, auto-reformatting, and fixed (i think) CWAL_TYPE_LISTMEM allocation metrics tracking. file: [8bfd823449] check-in: [d7ba485ecd] user: stephan branch: trunk, size: 467388)
2017-10-07
13:38
re-renamed a couple routines left mis-named by the strlen refactoring. file: [f52b103228] check-in: [a78283a20f] user: stephan branch: trunk, size: 466045)
2017-10-05
17:09
Merged (private) strlen-rewrite branch. This eliminates the 'length of 0 means to use cwal_strlen()' semantics from the major APIs (there may be a couple small outliers). My hands managed to survive, with the left pinky being only ever so slightly sore. file: [4de44d576a] check-in: [ef477c5d1e] user: stephan branch: trunk, size: 466026)

cwal core now sorts Object properties internally, making searches faster (on average). file: [562e5f7d62] check-in: [792bbb7ddd] user: stephan branch: trunk, size: 466454)
2016-09-09
19:21
Adding a preliminary CMakeLists.txt for use in CLion.    Also changed the UNUSED_VAR macro to an UNUSED attribute which appears to be more widely adopted by compilers. file: [ee769c5390] check-in: [d834ba36b3] user: calebg branch: s2-ndebug, size: 467519)
2016-08-30

Adding some build information to cwal. file: [6a9d41867a] check-in: [a88bdfc8b2] user: calebg branch: cwal-ndebug, size: 467606)
16:26
Removing NDEBUG and just using DEBUG to simplify sources. file: [6331870832] check-in: [a449dc869c] user: calebg branch: cwal-ndebug, size: 466813)
13:37
Fixing up the cwal non-debug build: * Switched around the amal build so that cwal_amalgamation.* files can be used without including other files. * Added ENABLE_SPEED_OPTIMIZATIONS and ENABLE_SIZE_OPTIMIZATIONS to config.make - ENABLE_DEBUG=0 make - ENABLE_DEBUG=0 ENABLE_SPEED_OPTIMIZATIONS=1 make - ENABLE_DEBUG=0 ENABLE_SIZE_OPTIMIZATIONS=1 make * Replaced all debugging double negatives with just a positive expressions: "#if !defined(NDEBUG)" is now "#ifdef DEBUG" * Added the UNUSED_VAR macro to prevent the 'unused variable' compiler warning. * Removed the "force assert() to always work" section in the test.c file. * Added CWAL_AMALGAMATION_BUILD to test.c so that it's possible to easily build the test with the amal build. * Literred UNUSED_VAR everywhere it was needed in the test.c file. file: [400e69b9d2] check-in: [fce3c1d39b] user: calebg branch: cwal-ndebug, size: 466972)
2016-08-25
20:44
Changed several *CWAL_INT/DBL derefs to memcpy() to avoid a bus fault on ARM. Had to work around gcc boneheadedness to do it :/. file: [049de06050] check-in: [4b1745c43f] user: stephan branch: trunk, size: 466918)
2016-08-20
10:32
Fixed a not-_quite_-right assertion in the Unique-type's finalizer which could incorrectly trigger during scope cleanup. file: [96a7eecbf9] check-in: [1627a35a2c] user: stephan branch: trunk, size: 465886)
2016-03-09
09:44
removed scope pointers from cwal_dump_value() and s2_dump_value() (they're just noise, as scopes are always stack allocated). file: [b0a55644a0] check-in: [104193e661] user: stephan branch: trunk, size: 465492)
2016-03-07
17:55
Ported s2 String.indexOf() to cwal_utf8_indexof(). Fixed a couple wrong no-match return cases in indexOf() (was still returning undefined (historical semantics) in some cases). file: [44fc55d614] check-in: [8b8f0837cd] user: stephan branch: trunk, size: 465524)
2016-03-05
20:52
Refactored s2's string case folding utilities into the cwal core. Need to eventually do most of the string utilities (indexOf, split, etc.), but i have an immediate use for this one. file: [41863a3ad0] check-in: [6ad30c288e] user: stephan branch: trunk, size: 467331)
2016-03-01
17:57
corrected an assertion message. file: [e3e2a7fcfb] check-in: [226b9b7f00] user: stephan branch: trunk, size: 465525)
17:15
removed some dead code, added an assertion to try to tickle and s2-level bug earlier on. file: [4b84fe72c8] check-in: [04e628eb7e] user: stephan branch: trunk, size: 465522)
16:36
merged in trunk, resolved conflicts. file: [b19110c11a] check-in: [9128a3b5d8] user: stephan branch: core-prop-interceptors, size: 470343)
16:31
removed an extraneous call which does the same thing as the thing which calls it. file: [dcdd0aa024] check-in: [75f2be92ce] user: stephan branch: trunk, size: 465805)
2016-02-29
11:44
os-x compile warning fix from Warren (his compiler is lying and/or misbehaving, though). Edit: okay, not lying, but performing an unexpected (to me) conversion from uint16_t to int. file: [c5958941da] check-in: [de4c5e6afe] user: stephan branch: trunk, size: 465857)
2016-02-28
13:55
Refactored the vacuum-safe flag from cwal_obase::flags to cwal_value::rcflags. s2_eval_ptoker() now uses a Unique instead of an Array for keeping its pending result safe (this is slightly cheaper), but in theory we can factor out that middleman (first attempt failed, so fell back to the Unique as an easy workaround). file: [fb58c30d89] check-in: [15092b9bd0] user: stephan branch: trunk, size: 465861)
11:26
split off cwal_refcount_t from cwal_size_t so that we can eventually (if needed) up the refcounts+flags to 64-bits on 32-bit builds without increasing cwal_size_t (which would have a higher overall cost). Stole another (the 6th) refcount bit to allow us to move the vacuum-safe flag from containers to values. file: [4ea8898003] check-in: [6f574d3f55] user: stephan branch: trunk, size: 465745)
10:56

child-rescoping fix for tuples (assertion triggered). file: [930eab5b90] check-in: [0c897fd853] user: stephan branch: trunk, size: 465718)
14:57
tuple docs and an iteration error check fix. file: [7835437e3f] check-in: [3ceffbf8b9] user: stephan branch: cwal_value_pair, size: 465712)
13:12
omg facepalm. The automatic resizing of hashes was losing their kvp flags. Thus scope storage failed to retain const flags only after having enough vars to cause it to resize. file: [26431203d2] check-in: [2ac9af21ff] user: stephan branch: cwal_value_pair, size: 465705)
01:25
okay, got carried away: discovered that hashes as scope storage fail to trigger const violations on s2 assignments, at least in one of the unit tests (but not in the interactive shell, for reasons unknown). Too tired to debug it further now. file: [9834e2b1fc] check-in: [42ddd6cf8c] user: stephan branch: cwal_value_pair, size: 464526)

minor tuple touchups. good night. file: [8e597b05e3] check-in: [fe58f61202] user: stephan branch: cwal_value_pair, size: 463629)
23:38
changed tuple hashing to just use the ptr-hash instead of hashing all elements. We might want to revision that later for use with tuples as hash keys (for use in simulating sets via hash tables). Edit: nevermind: hash keys' hashes have to be constant, and tuples are not, so this is the right hash algo. file: [99f56a5684] check-in: [b8fcba87c5] user: stephan branch: cwal_value_pair, size: 463541)
23:15
a small start on the CWAL_F_IS_VISITING transition to CWAL_RFC_IS_VISITING. file: [db21713233] check-in: [1006c5a9dd] user: stephan branch: cwal_value_pair, size: 463418)

cwal_value_may_iterate() now works for tuples. file: [70290a01b5] check-in: [efcb1523c8] user: stephan branch: cwal_value_pair, size: 463122)
22:18
Added foreach() support for tuples, working like arrays. And stole another refcount bit to get the is-visiting flag for cwal_values (needed for tuples and uniques, though uniques don't currently use it (they really should)). So far 5 refcount bits stolen for flags. file: [3c561365c3] check-in: [515942ded1] user: stephan branch: cwal_value_pair, size: 463061)
21:42
refactored pairs as tuples (fixed-length arrays). Still need to add foreach() support. file: [ecbfbcc56d] check-in: [5cc361ae64] user: stephan branch: cwal_value_pair, size: 462101)

17:12
changed semantics of cwal_array_visit/visit2() when it comes to NULL entries (they are no longer skipped over, so that iteration can keep track of the indexes properly if it wants to, without having to jump through hoops to do so). file: [a56bedba9e] check-in: [8ecd168f4b] user: stephan branch: trunk, size: 455466)

i had a property setter interceptor working, then broke it, and am now too tired (and this machine has no debugger). Someone's getting cleaned up when they shouldn't, random crashes.

wrote what turned out to be a novella on plans for/thoughts on improving s2_estack to notably improve s2's internal value ref/unref handling (now that my understanding of the intricacies ref handling in the context of temp values, in particular in conjunction with string interning (or value interning in general), has finally caught up to the code\!). file: [7b407ba869] check-in: [dcf19ee9c8] user: stephan branch: trunk, size: 453512)
15:37
added single highest-ever refcount to cwal_engine::metrics to help inform decision-making about hijacking more refcount bits for per-value flags.

Minor tweaks to get it compiling (again) with CWAL_SIZE_T_BITS=16. file: [54a1e4e3f1] check-in: [6509fa8dd3] user: stephan branch: trunk, size: 452591)
18:55
Replaced the remaining relevant cwal_obase::flags with cwal_value:rcflags (did indeed need all 4 bits, but freed up 3 cwal_obase::flags bits for potental later use). Pseudo-containers (namely CWAL_TYPE_UNIQUE) can behave sanely during cleanup. e.g., they now participate in the gc queue and cycle-breaking during cleanup. file: [e29217b3a4] check-in: [c391d2ccce] user: stephan branch: value-refcount-flags, size: 452592)

17:25
Initial refactoring for encoding a few bits of flags in cwal_value::refcount. Both th1ish and s2 tests pass with these changes, though we're internally encoding the refcount differently now. Initially 4 bits, but that will likely drop to 2. file: [6fd0dda919] check-in: [ac9cf983f2] user: stephan branch: value-refcount-flags, size: 450993)

Worked around a scope-cleanup crash caused by a Unique-typed value containing cycles (same problem we saw with cwal_value_pair experimentation). This case is a good argument for stealing bits from the refcount for a couple internal cwal_value flags. file: [0e35174460] check-in: [e1076c4252] user: stephan branch: trunk, size: 447204)

minor change to how cwal_weak_ref is freed/allocated, to make use of the chunk recycler. Minor doc tweaks. file: [b7e58f10e6] check-in: [db36c3e32a] user: stephan branch: trunk, size: 444621)
01:09
Added cwal_value_pair type, but shortcomings elsewhere make it clean up improperly when there's recursion involved (because it's not a full-fledged container, and is not privy to the cleanup treatment involved). Not sure if this is yet worth the hassle (and it asserts() now in s2 in very simple cyclic cases).

started adding some infrastructure to allow a cwal_engine to be marked as "dead", which basically means "in a debug build, it would have asserted by now, but this is not a debug build."

added workaround: string interning no longer re-uses an interned string when a copy in the interning table has a refcount of 0. Interned values should now not introduce any weird/hard-to-find differences from other values.

16:14
characterized/documented an inherent incompatibility with string interning and the use of temp values (specifically, strings, with a refcount of 0), in which a downstream call can (_seemingly_ legally) nuke a value created higher-up in the call chain, because string interning confuses the "real" ref count of temp values. Aha... there might be a workaround for this in interning itself (don't use interned copies if their refcount is 0). file: [acb1e31cd6] check-in: [970642d496] user: stephan branch: trunk, size: 432996)

17:33
Changes in semantics how cwal_prop_set() and friends report various cases, so that we can move some constraint checks into cwal, so that s2 does not have to do duplicate lookups to get the same feature. file: [f91c5fb0e1] check-in: [6dbf89b73c] user: stephan branch: trunk, size: 405391)
13:05
core: refactored the chunk allocator to remove all dynamic memory overhead plus all overhead related to the tracking of each chunk (it is now stored in the chunk itself). This means we can only recycle stuff larger than (sizeof(void*)+sizeof(cwal_size_t)), but we were doing that, anyway, except perhaps in some tiny buffer cases. file: [6a9b20c674] check-in: [435ccd17b7] user: stephan branch: trunk, size: 404253)

core: platform workaround for my ARM, which is bus-faulting on a particular deref of a static/const pointer. Accessing the same pointer via anoether route does not bus-fault it. file: [27874eafc2] check-in: [319b16b847] user: stephan branch: trunk, size: 407669)

15:42
core: added a couple new memchunk metrics, disabled the memchunk recycler as the string recycling fallback because it is triggering a valgrind warning via memset() via cwal_value_new() - to be investigated later. file: [c224374adb] check-in: [0687ce7bc3] user: stephan branch: trunk, size: 407298)
2014-12-03
16:59

2014-11-29
20:59
Factored out cwal_memchunk::left. 90% of the code was either setting it or just asserting that it was set. file: [e162139af5] check-in: [3fc1976b1d] user: stephan branch: trunk, size: 396911)
20:31
Moved cwal_engine::eWeak into cwal_engine::recycler, fixed consolidation of Value- with non-Value types in a single recycler: each recycler must be specific to a certain base type so that we can use the list-linking members to build the lists. file: [16051a4db4] check-in: [8ba45681a0] user: stephan branch: trunk, size: 398245)
17:17
Added per-recycling-bin hit/miss counters. file: [bb9141233c] check-in: [520ed62f5d] user: stephan branch: trunk, size: 396779)

14:13
core: Value recycling bins are now allotted by the size of the Value, so like-sized Value types get grouped. i.e. more effective use of the recycler. However, this does not jive with the per-type-based configuration of bin sizes, but is an overall improvement with no losers, so we'll find a different configuration mechanism. file: [8d1428f372] check-in: [97b8ce3372] user: stephan branch: trunk, size: 393914)

core: improvements in the chunk recycler, and more memory gets recycled. file: [26be69ed4f] check-in: [a9a7aa2637] user: stephan branch: trunk, size: 387905)
01:07
core: consolidated array/buffer memory recycling and made it usable for other purposes. Some types (hashes, z-strings) contribute to the recycling pool but do not yet draw from it. This cuts mallocs by just over 60 in the amalgamated unit tests, while costing minimal mangement memory (1-2k, allocated once). There is tweaking to be done and more stuff which can be recycled this way, but it's a promising start. Valgrind is happy. file: [3b9c035494] check-in: [94bd6ae976] user: stephan branch: trunk, size: 380348)

16:29
Minor but subtle semantics changes in cwal_function_call() and friends ("self" is now made vacuum-safe) and cwal_exception/propagating_set() (now uses unref instead of unhand when reseting/clearing the value). Accommodated that in s2/th1ish. Added cwal_utf8_char_next() utility function. In s2: started experimentation with the "new" keyword, but it is disabled and incomplete. Yeah, that is more than i wanted in this commit. file: [9b01d648ba] check-in: [bd8ecee444] user: stephan branch: trunk, size: 369629)

20:46
core: minor internal tweaks in prep for some experimentation in s2 which will expose scope variable storage Objects to script code. cwal_function_call() now refs/unhands its result value (currently same effect as before, but to account for potential upcoming experimentation). file: [b693662825] check-in: [d9d4be0daa] user: stephan branch: trunk, size: 368788)

core: refactored cwal_hash so that we can resize hashtables (APIs for that still pending). Negatively affects alloc counts (currently +1 per table) but the Value part of the hash is now recyclable and the hash table memory is currently reusable as array list memory. file: [61d50c2e3c] check-in: [310ba44db8] user: stephan branch: trunk, size: 354501)

16:13
core: found another optimization, recycling cwal_buffer memory (5 buffers' worth) similar to how cwal_array list memory is recycled. In the s2 unit tests this reduces the aggregate alloc count by 3.5-9%, depending on their buffer usage, with the _potential_ for a higher peak usage of (sizeof recycled buffers), but that depends on how the app uses buffers. file: [e1e0ad0d84] check-in: [1648e371e7] user: stephan branch: trunk, size: 348535)

Added cwal_prop_set_XXX_with_flags(), to support setting hidden properties from s2. Fixed a pointer misuse in cwal_value_may_iterate() which caused it to return unpredictable results. file: [0915092e70] check-in: [4434f6db64] user: stephan branch: trunk, size: 340744)

04:40
Added cwal_json_output_opt::cyclesAsStrings, which causes cycles to be output as some debugging-only string representation, rather than causing an error. file: [c8601b3adf] check-in: [640531cd49] user: stephan branch: s2-semicolons, size: 339855)
02:20
Fixed a major blunder in cwal_engine_vacuum(), which did not start gc-queuing mode when cleaning up the scope. 7 hours debugging that. Amazing this has not backfired until now, but it requires certain conditions before it trips up. file: [a18e5772bd] check-in: [e377a0525b] user: stephan branch: s2-semicolons, size: 339854)

2014-06-24
22:16
re-introduced cwal_propagating_set() and friends, as a place to store a single auto-propagating value (both th1ish and s2 implement this themselves, but that's no longer needed). file: [a4c13df62b] check-in: [6a720a9358] user: stephan branch: trunk, size: 339231)

minor z-string metrics tweak: now assumes (and counts) a NUL byte (only for metrics purposes). file: [a3cbce8d53] check-in: [df4c4776d1] user: stephan branch: trunk, size: 338749)
19:45
cwal core: X- and Z-strings now participate in value recycling (in the same pool, b/c they have the same sizeof()). Only their "shells" recycle, not their string bytes. Fixed a char-should-be-int case which had not yet caused a problem. file: [b37d96e995] check-in: [ec0d73eba5] user: stephan branch: trunk, size: 338564)

2014-06-21

cwal_buffer_fill_from_FILE/filename() now try to pre-allocate the buffer based on the guessed size of the file (based on seek-probing), falling back to the default strategy. file: [d7803f063b] check-in: [5085bfa2c5] user: stephan branch: trunk, size: 337095)

Changed how cwal_engine manages its exception handle - it now takes uses ref/unhand, instead of not referencing at all. file: [1c5f7c8ceb] check-in: [e801bfc408] user: stephan branch: trunk, size: 335404)

2014-05-16
21:22
cwal_function_call_in_scope() now vaccuum- and sweep-proofs the function for the duration of the call, to avoid that a recursive cleanup potentially nukes an temp function called at its decl point. file: [9eced6b08a] check-in: [25ee81e2ed] user: stephan branch: trunk, size: 334834)
19:00
Fixed broken cleanup ordering in Natives (which i recently swapped), as this breaks natives which use their own properties in their cleanup (namely linenoiseish's auto-save-at-finalize). file: [8657a3c712] check-in: [242ab76d5d] user: stephan branch: trunk, size: 332677)

19:07
Added getter/setter for cwal_engine client data. Found, quite by accident, the 'dangling native' which was breaking vacuuming in th1ish (cwal_engine::prototypes). Vacuum now works in th1ish's global scope :-D. Valgrind agrees. file: [96146116a6] check-in: [961ce26847] user: stephan branch: trunk, size: 329841)

Minor cleanups. Increased StringPadSize to 8, as this gives us a big boost in efficiency on large scripts. Once again removed the 'phantom ref' on interned strings. Improved api.ob API a bit by returning api.ob from the void-returning methods. file: [77b52d12dc] check-in: [2c2187749f] user: stephan branch: trunk, size: 328569)

11:31
Found the hashing (int range) culprit which broke interning lookups. Other tweaking with vacuuming and interning. Added a kludge ++refcount on interned strings upon insertion to save them from vacuuming. i don't like that, but it does save memory. Switched string hash algos again. file: [702f22aa50] check-in: [a6668115e9] user: stephan branch: trunk, size: 327928)

Refactored cwal_engine_vacuum() to... drum roll, please... no longer copy anything. It now only rescopes stuff, so no allocation needed, which means no error cases unless it detects memory corruption (assertion). file: [3c53218b22] check-in: [ae032f2d59] user: stephan branch: trunk, size: 328360)

Started adding (untested, except that existing code/tests still work) infrastructure for making individual values, and those they reference, safe from vacuuming up.

cwal_dump_allocation_metrics() now counts scopes differently (only allocated ones) because they skew the stats unduly (and unfairly ;). file: [44269054e7] check-in: [e4e693eb9f] user: stephan branch: trunk, size: 326574)

Vacuum now works as a drop-in replacement for sweep in th1ish :-D meaning that, in principle, it is (with proper script structuring) possible to create a leak-free, really-long-running scope, regardless of cycles. :-D! Interestingly, vacuum does not often catch more values than sweep, so it will be optimized to normally sweep, and replace every Nth sweep-up with a vacuum. file: [771bd0a749] check-in: [4ce80bab79] user: stephan branch: trunk, size: 325981)

this variant of cwal_engine_vacuum() works for the first 3 th1ish unit test scripts, then falls apart somewhere, but is certainly better than the previous iteration. file: [07759d8973] check-in: [7a0a0b3e7a] user: stephan branch: trunk, size: 325350)

Added cwal_prop_flags_v(), admittedly a quick-hack measure for th1ish which needs to be improved upon at some point. file: [3c1c567878] check-in: [73df633530] user: stephan branch: trunk, size: 325058)

more work on vacuum. Seems it cannot be dropped right in to th1ish for reasons as yet determined but very possibly incompatibilities with vacuuming assumptions. file: [c17ae319f8] check-in: [e276ed0f1d] user: stephan branch: trunk, size: 324073)

Introducing cwal_engine_vacuum(), an experimental algo which cleans up all non-variable values which are themselves not reachable via variable refs/containers. Fixed two bogus assertions while doing so. file: [8f72c11b15] check-in: [8f455e260b] user: stephan branch: trunk, size: 323324)

Added array list peak memory to the allocation metrics. Removed an old/arguable assertion which, for reasons completely inexplicable, is trigged only with this change. file: [b298b12c90] check-in: [bc61ad3eb4] user: stephan branch: trunk, size: 318934)

15:57
Another tweak to the refcounting (or not) of interned strings. Moved determination of whether a given string is internalizable to a predicate function the cwal_engine_vtab interface. The default impl behaves as before. th1ish adds its own impl which basically limits interning to very short strings an arbitrary identifiers. file: [803e881182] check-in: [7588890cb3] user: stephan branch: trunk, size: 303907)

minor optimizations and tweaks. print() and api.io.output() now outputs Buffers as their content instead of a type@ptr string. file: [6d84083b81] check-in: [9cc51aba6e] user: stephan branch: trunk, size: 302455)

fixed an unused var for non-tracing builds. file: [2c1841ac7e] check-in: [5dfd7a164d] user: stephan branch: trunk, size: 302416)
20:40
minor internal cleanups and one optimization which cut 5.thish's mallocs down by almost two order of magnitude :-D. Happy accident, actually, but the reason for it is clear - mallocs are down notably across the board for all test scripts. file: [a69000a4d3] check-in: [6321c72aba] user: stephan branch: trunk, size: 302305)
18:35
Added cwal_callback_hook and friends, and refactored th1ish to inject its argv/this vars from there. This generically fixes the problem of this/argv/argv.callee resolving to one from a higher-up callback. Removed the workaround added for this yesterday. file: [5e7d0d356e] check-in: [4ea181bb5d] user: stephan branch: trunk, size: 302257)

fixed a slightly wrong assertion. file: [7f9f30f8e8] check-in: [db8d1e8273] user: stephan branch: trunk, size: 301486)
22:45
moved th1ish_inject_callback_argv() into public th1ish API (will need it elsewhere), some const correctness fixes in the core API. file: [8b39fd2d1e] check-in: [f71379525b] user: stephan branch: trunk, size: 301465)

Fixed a problem in cwal_array_take() which caused it to not take built-in values. Doc update. file: [a0f0c3f794] check-in: [c59879843c] user: stephan branch: trunk, size: 301451)

20:59
Fixed cwal_array_copy_range() (and thus Array.slice()) to work as advertized. Fixed a wrong assumption (assertion) in Array.shift() binding. file: [051e95dae0] check-in: [02490653cf] user: stephan branch: trunk, size: 299556)
20:00
Added cwal_array_take() and changed cwal_object_take() to reprobate (instead of transfer reference ownership) if needed because that's the only way to provide the client with sane return mechanism. Added Array.pop() binding. file: [18ce6225e6] check-in: [d1ed6fc7da] user: stephan branch: trunk, size: 299447)
2014-02-19

Removed an extraneous rescoping of a re-used interened strings. Added yet more comments to the interned strings notes. file: [1653582f70] check-in: [a98e648aaf] user: stephan branch: trunk, size: 298591)

22:14
Fixed compile warnings which for some reason do not show up when i compile in this tree, but do in another. Weird. file: [7e60a7e2b3] check-in: [591d051369] user: stephan branch: trunk, size: 297339)

2013-07-21
18:26
Added Object.toJSONString(). Still missing overridable toJSON() support. Moved th1ish_value_XXX_part() to cwal_value_XXX_part(). Added String.applyFormat(). file: [6cd1479eb6] check-in: [77d1757a8b] user: stephan branch: trunk, size: 296782)
2013-07-20

Optimized string recycling to re-use strings based on a first-close-fit algorithm (was exact-fit). This cuts mallocs in the th1ish test scripts anywhere from a few percept, up to 36%. file: [5b6d890ef3] check-in: [9ee156625d] user: stephan branch: trunk, size: 294345)

cwal_value_get_cstr() now also treats buffers as strings. file: [2784b63e3d] check-in: [89039d20a7] user: stephan branch: trunk, size: 291272)
2013-07-19

Added cwal_engine_type_name_proxy() and friends and tweaked th1ish to use it. file: [2615c349eb] check-in: [aa092439d4] user: stephan branch: trunk, size: 290956)
11:09
More work on buffer formatting. cwal_prop_xxx() and friends now have a const-correct container parameter. file: [f486c1a1c5] check-in: [9557396db3] user: stephan branch: trunk, size: 290308)

Added very primitive recycling of the lists which back Array values. This cuts alloc count anywhere from about 1 to 7 percent in the current th1ish test scripts. file: [8b94e389a8] check-in: [491ad36c59] user: stephan branch: trunk, size: 286895)

23:23
Much tinkering with the weak references support. Refcounted them and share all instances pointing to the same memory. Most of this is untested, though (no use case yet :/). Added APIs for (un)registering client-side memory for weak referencing. file: [dbfb68b9d4] check-in: [e0e531af6d] user: stephan branch: trunk, size: 285541)

Experimenting with accessor interceptors, but this is not quite the way there. file: [b01641a96c] check-in: [5299a543a6] user: stephan branch: accessor-interceptors, size: 284323)
2013-07-03

added experimental/broken cwal_engine_sweep_non_vars(). Does not work right but want to play with it later. file: [af063a804f] check-in: [cdec608b94] user: stephan branch: trunk, size: 282393)

14:04
Added weak value reference support. This allows, e.g., N bound natives with mutual relationships to safely figure out if the other endpoint has been destroyed. file: [8e26f22498] check-in: [fab8ad55e3] user: stephan branch: trunk, size: 276070)
2013-07-01
22:11
Introducing z-strings (similar to x-strings except that cwal owns their memory). This cuts the cost of th1ish's slurpFile() function by half because it removes an extra copy. Increased cwal_buffer_fill_from() buffer to 4kb to reduce the number of reallocs(). file: [a909e307ad] check-in: [8c04f5388e] user: stephan branch: trunk, size: 270043)
17:31
Added (several prototypes).compare(). Added shell_extend.c as an easy way for clients to install their own script-side functionality into the default shell app. file: [163aca8282] check-in: [91250213b2] user: stephan branch: trunk, size: 268882)
16:24
Expanded the function/args-state APIs a bit. Used them to implement Function.sourceInfo() type-safely. file: [7e70bc005c] check-in: [5f7fe4b6bc] user: stephan branch: trunk, size: 268833)
15:37
Revamped cwal_new_function() and friends to take a type ID tag for the state parameter, to safify some of the current casting, enable 'multiple-context' callbacks, and a couple other minor things i would like to try out. file: [524e1a8d18] check-in: [cb4072639e] user: stephan branch: trunk, size: 268391)

Scope property objects now get their prototype removed so that they do not resolve members of the prototype via variable resolution. file: [2c4c22e188] check-in: [56974219ac] user: stephan branch: trunk, size: 267876)

2013-06-19
16:38
Fixed an argument-handling-related memory corruption case caused by a well-intentioned optimization (which was just removed). This also fixes the bug that returning argv from a function lead to unexpected results (empty array). file: [2717721d93] check-in: [90aad2442f] user: stephan branch: trunk, size: 257062)

cwal_value_prototype_set() no longer allows (what it can recognize as) cycles between the child and its prototype. file: [e176ebf1a5] check-in: [69ab011467] user: stephan branch: trunk, size: 256933)

Started work on adding an option to disable doubles in cwal. It basically just changes cwal_double_t to be cwal_int_t. file: [97fa6e14df] check-in: [264317163d] user: stephan branch: trunk, size: 256387)

cwal_hash_insert/remove() now fail with CWAL_RC_ACCESS if called while iterating over the table. file: [8a07d2b48c] check-in: [9e0415bcd6] user: stephan branch: trunk, size: 253131)
11:58
Fixed bugs in cwal_hash search which caused it to not communicate left-hand chain member, which lead to broken linking on hash collisions. file: [94b840447f] check-in: [7374119631] user: stephan branch: trunk, size: 252709)
2013-06-14

23:54
Added prototype/experimental hashtable support to th1ish. Had to uplift some static cwal funcs into cwal_internal.h to do it. Finally tested ability for Natives to rescope their children (and discovered the problems involved). Hashtables still triggering at least one outstanding re-parenting/lifetime-related assertion in some script constructs. file: [2a3ddfe6d7] check-in: [670a0ad9c5] user: stephan branch: trunk, size: 240828)
2013-06-12

2013-06-10

Added integer -1 and double -1.0 to the list of built-in constant values because they appear so often in script code. file: [45e7d2e146] check-in: [54989ac4fa] user: stephan branch: trunk, size: 237396)
20:46
Removed some old comments and a stray debug message. Tweaked size of string interning table size again. Cleaned up the main test app a bit. file: [eb6a4baf0b] check-in: [0c0a865f24] user: stephan branch: trunk, size: 237004)
20:03
Fixed inconsistent orderings in cross-type value comparisons. Fixed a huge bug in the new cwal_ptr_table linked list which caused several megabytes of tables to be allocated (one per string). file: [85e51f5047] check-in: [f4773da793] user: stephan branch: trunk, size: 237265)
17:25
Fixed a bug in the ptr_table remove-entry op which traversed tables unnecessarily. Renamed cwal_interned_search_v() to cwal_interned_search_val() file: [8ec4e2df6d] check-in: [11ea684831] user: stephan branch: trunk, size: 236296)
17:14
Refactored cwal_ptr_page to a linked list and replaced cwal_ptr_table::pages (type=cwal_list) with that linked list. Saves a small tick of memory when interning strings, removes several potential malloc error cases (on OOM), and has the same performance characteristics as before. file: [46bebcdf9a] check-in: [823220ffed] user: stephan branch: trunk, size: 236326)
15:24
Added cwal_array_reverse(). cwal_array_sort() now fails if called while the array is being visited/traversed. Doc additions. file: [03190aa81f] check-in: [8079c5b03d] user: stephan branch: trunk, size: 238197)
2013-06-09
19:48
th1ish: minor tinkering. Removed the limit that 'importSymbols' only works for the calling scope (too onerous given th1ish's tendency to create scopes whenever it can get away with it, and a function call's scope starts while the parameters are being processed, as a memory-saving measure). file: [66f6d10df5] check-in: [32806d9602] user: stephan branch: trunk, size: 237778)
17:45
Fixed: prototype values are now re-scoped when child properties are re-scoped, and are unref'd using cwal_unref_from() instead of cwal_value_unref() (so they get re-probated if needed). Fixes a problem in th1ish with returning a new prototype value from a sub-scope. file: [b5b327911f] check-in: [3f002b6bc3] user: stephan branch: trunk, size: 237581)

Changed an assertion to a proper return value in cwal_prop_set(), and removed its requirement that its key be non-empty (for consistency). file: [b9896b611b] check-in: [9083d938ec] user: stephan branch: pcre, size: 233994)

Seem to have found a decent heuristic for working around the obj.prop-gets-upscoped-and-cleaned problem by moving values _back_ into probationary state _if_ they would be cleaned up by a container which lives in a lower scope than the value. Allows removal of the 'extra ref' th1ish had to add before this. file: [74f7323454] check-in: [8f9e77f3ea] user: stephan branch: pcre, size: 233965)

Removed an ambiguity in the handling of empty string keys in cwal_var_set() vs cwal_var_set_s() and cwal_var_set_v(). file: [ff3b06491f] check-in: [957ae67c59] user: stephan branch: trunk, size: 229969)

20:06
Changed how cwal_scope::mine::r0 is cleaned up. cwal_exception_set() no longer ref/unref's the exception (causes problems downstream). Forced a single refcount increase on shared interned strings the first time they are re-used to work around a lifetime problem. It's not a 100% solution but it's close. file: [86828d9f01] check-in: [63ade6e28a] user: stephan branch: trunk, size: 223213)

more x-string-related fixes and some prep for z-strings (like x-strings, but the cwal_string owns and deallocates the (char*)). file: [f1710e2a14] check-in: [0edafb49ef] user: stephan branch: trunk, size: 222668)

cwal_new_string() and friends now no longer ref() a string which came from the internalizer. It _seems_ we don't really need to. file: [275490bcd2] check-in: [f67d411781] user: stephan branch: trunk, size: 215634)

pulled in [refcount0] branch, which changes how refcounting working (starts from 0 instead of 1, with 0 having a special "probationary" status). file: [b9432a6579] check-in: [f518911f69] user: stephan branch: trunk, size: 214408)

Tweaking of interned string refcount mechanics, but just cannot seem to get what i need here. Might need to special-case string destruction for this. file: [c3e0eaecec] check-in: [2cbe4802e5] user: stephan branch: refcount0, size: 211788)
17:11
Added cwal_scope::mine::r0 list to keep extra track refcount==0 values. sweep-scope is now much faster and safer. file: [cbf72050c4] check-in: [ef4c8f9e67] user: stephan branch: refcount0, size: 210735)

minor tinkering before bed. Seems to work so far. file: [d03de23e08] check-in: [6be90896fc] user: stephan branch: refcount0, size: 210022)
22:30
changed value refcount to start at 0, meaning no my ref held by the scope. This _might_ give me semantics off of which i can vastly improve the memory usage in th1ish, by proving a "purgatory" state where a value has not yet gotten an explicit reference. Previously we had start refcount==1, with the 1 being justified as the holding scope, but that causes us grief in script implementations (orphaned values held too long) and an adds ambiguity between "purgatory" and "refcount was _reduced_ to 1". file: [4ea2ceb93e] check-in: [7ca566b740] user: stephan branch: refcount0, size: 210003)

14:28
Added a new cwal_scope_prop_XXX() API to supplement or replace the cwal_var...() bits. Changed how Function call()s return their value, to make cwal_result_{s,g}et() unnecessary and handle result value lifetime better from the client. file: [74429ffaf1] check-in: [0e89645697] user: stephan branch: trunk, size: 203956)

Fixed a bug in kvp recycling (counter was wrong). Added scope recycling, which shaves a significant number of mallocs off of my test code and in s1. file: [4e6955a791] check-in: [24a0e9a8f2] user: stephan branch: trunk, size: 181031)

Fixed var_set behaviour to set the var in the scope it is found in. Need to optimize this, though (currently 2 lookups). file: [bd918596a9] check-in: [baa62c845c] user: stephan branch: trunk, size: 171685)

Internal optimization to cwal_value_is_builtin() which shaves a percent or so of the runtime from my test app. file: [a76d66ce66] check-in: [a54b88187c] user: stephan branch: trunk, size: 161089)

Refactored the key/value pair support to work with any cwal_obase type (object, array, function, native). Functions and Natives may now contribute to cycles. file: [616f871090] check-in: [c111db9842] user: stephan branch: trunk, size: 160119)

12:45
Removed cwal_engine::resultScope b/c it causes new lifetime issues. Result value is now simply moved into the parent scope for ownership purposes (nothing an occassional cwal_scope_sweep() won't take care of). file: [bbdcfb93b1] check-in: [e99d61e441] user: stephan branch: trunk, size: 149848)

Moved cwal_obase::list into cwal_array. Fixed json code to use cwal_object::kvp. Removed the cycle-counting code, since the current API doesn't use it. (We might need it later, though.) file: [fd39af08b2] check-in: [77b2583370] user: stephan branch: obj-kvp-list, size: 129240)

Fixed some bugs in the scope cleanup code triggered by interned strings, and incidentally ended up trimming the algo from about 40 lines and two nested loops to only 1 functional line (and several tracing/checking lines) in a single loop. file: [4eba6f7b1c] check-in: [02af50b668] user: stephan branch: trunk, size: 127692)

Refactored recycling list to use value linked lists, removing the 5 mallocs needed for the lists and cutting the cost of the recycler a bit. file: [abdbb14249] check-in: [1489228c0d] user: stephan branch: trunk, size: 127022)
11:13
Refactored delayed GC to use the new linked list, cutting its memory cost to a single pointer, removing any allocation it used to do, speeding GC-push up to O(1), and removing some unrecoverable error cases caused by OOM conditions. :-D file: [d049fb1f1f] check-in: [c29b48dd13] user: stephan branch: trunk, size: 128081)
10:43
Refactored scope/value parenting to use a linked list. Costs 2 pointers per value but ends up costing fewer mallocs and less memory overall because some (large) scope-level overhead goes away. This also makes some ops O(1) which were previously O(N). file: [a1eb6b1337] check-in: [1f8844853b] user: stephan branch: trunk, size: 127569)

Tweaking of the string-interning table size and hash function (found a combination i like better). Initial POD destruction looks good except i am going to run into a problem with lower-level scopes when they get refs to strings from higher-level scopes. i think i can only fix this by adding a scope ptr to each value :/. file: [1930b5fe80] check-in: [f0b3dff0a7] user: stephan branch: scope-parenting, size: 111151)

Added string-interning support. Now all new strings with the same bytes get auto-interned/re-used. There might be a cross-scope ownership problem here, but only (i think) if we leave the "strict scope ordering" realm (e.g. for closures, which are not a high-prio feature). file: [4eb5b19e73] check-in: [32a0ade6f0] user: stephan branch: trunk, size: 94738)

removed cwal_engine::scopes, subsumed by the cwal_engine::current linked list we already had. file: [37c16c95f3] check-in: [0062bd8ecf] user: stephan branch: trunk, size: 87640)

started refactoring into two headers (public+internal). file: [daa01f2bb7] check-in: [fc05f69b2c] user: stephan branch: trunk, size: 88771)

merged in cycle-counting branch. Works at least as well as it did before and has basic support for graph destruction for "relatively little" cost. file: [2515356da5] check-in: [e58a47936d] user: stephan branch: trunk, size: 88384)

Added initial value allocation recyler. Lots of other tweaks, improvements, and debug output. file: [26a86ed437] check-in: [02ab3dc56e] user: stephan branch: cycle-counting, size: 88473)

minor tinkering. Fixed, i think, a future bug when cycle counting more than once. file: [8f0109aba0] check-in: [92dd48c7c1] user: stephan branch: cycle-counting, size: 82535)

Added boatloads of API docs. Still far from finished (many still to be copied from cson). file: [57d4e38ab6] check-in: [6c4c514f74] user: stephan branch: cycle-counting, size: 77835)

this is a beautiful thing when seen through the eyes of valgrind... file: [0beff61a14] check-in: [354aa42b4e] user: stephan branch: cycle-counting, size: 74729)

this one looks a bit better. Fixed a REALLY dumb flags bitset bug which caused a mis-diagnosed is-destructing check. file: [87f0ae737b] check-in: [aed1986bae] user: stephan branch: cycle-counting, size: 74729)

Improved the [f9924f2539] workaround (i think). file: [a04be01d44] check-in: [5a0e3b69cf] user: stephan branch: cycle-counting, size: 72100)

Auto-cycle-count/clean is now done at scope-pop, but this is not a complete solution because values can outlive a scope. file: [df7218aeec] check-in: [303510704d] user: stephan branch: cycle-counting, size: 74136)
00:35
First cyclic free-up demonstrated when the parent scope expired :-D, but requires that one run the cycle-counter first :/. Making that transparent is on the TODO list for the weekend :D. Reminder to self: we might be able to put that in the Scope cleanup. file: [544e547565] check-in: [5b1208c9f8] user: stephan branch: cycle-counting, size: 70855)

Tinkering with value-scope parenting, but the built-in values just threw a wrench in it. file: [25c2022877] check-in: [c8298bc6d1] user: stephan branch: trunk, size: 68259)

Tinkering with various loads for the ptr table. 90% only causes 2 tables under the right circumstances, the second one only lightly loaded. file: [289d6d4f5a] check-in: [91da9fef15] user: stephan branch: trunk, size: 46423)

ptr table almost works right, but page->entryCount seems to be off by one sometimes? To check tomorrow... file: [f20b867f5d] check-in: [0c98670772] user: stephan branch: trunk, size: 43449)
