Roberto Ierusalimschy	ce6f5502c9	'luaH_get' functions return 'TValue' Instead of receiving a parameter telling them where to put the result of the query, these functions return the TValue directly. (That is, they return a structure.)	8 months ago
Roberto Ierusalimschy	ba71060381	Removed "bulk operations" Negligible performance gains don't justify extra complexity.	8 months ago
Roberto Ierusalimschy	3823fc6c81	Added "bulk operations" to arrays A few operations on arrays can be performed "in bulk", treating all tags of a cell as a simple (or a few) word(s).	8 months ago
Roberto Ierusalimschy	52aa2b5d24	Details - 'unsigned int' -> 'unsigned' - Some explicit casts to avoid warnings - Test avoids printing the value of 'fail' (which may not be nil)	8 months ago
Roberto Ierusalimschy	cc2b66c856	Removed type 'varint_t' size_t should be big enough to count the number of strings in a dump. (And, by definition, it is big enough to count the length of each string.)	8 months ago
Roberto Ierusalimschy	65b07dd53d	API asserts for illegal pops of to-be-closed variables	8 months ago
Roberto Ierusalimschy	7237eb3f1c	Fixed warnings from different compilers	9 months ago
Roberto Ierusalimschy	165389b27b	New interface to function 'luaL_openselectedlibs' Instead of preloading all non-loaded libraries, there is another mask to select which libraries to preload.	9 months ago
Roberto Ierusalimschy	c8121ce34b	Revising code for Varint encoding in dumps - Usign lua_Unsigned to count strings. - Varint uses a type large enough both for size_t and lua_Unsigned. - Most-Significant Bit 0 means last byte, to conform to common usage. - (unrelated) Change in macro 'getaddr' so that multiplication is by constants.	9 months ago
Roberto Ierusalimschy	7360f8d0fd	Removed deprecated function 'setcstacklimit'	9 months ago
Roberto Ierusalimschy	6063c47031	Field 'lastfree' changed (back) to 'Node *' Due to allignment, it is already using the space of a pointer, and a pointer generates slightly simpler code.	9 months ago
Roberto Ierusalimschy	0c9bec0d38	Better handling of size limit when resizing a table Avoid silent conversions from int to unsigned int when calling 'luaH_resize'; avoid silent conversions from lua_Integer to int in 'table.create'; MAXASIZE corrected for the new implementation of arrays; 'luaH_resize' checks explicitly whether new size respects MAXASIZE. (Even constructors were bypassing that check.)	9 months ago
Roberto Ierusalimschy	c31d6774ac	Details	9 months ago
Roberto Ierusalimschy	108e0bdc84	Merge branch 'master' into nextversion	10 months ago
Roberto Ierusalimschy	b34a97a4af	Small optimization in 'luaH_psetint' It is quite common to write to empty but existing cells in the array part of a table, so 'luaH_psetint' checks for the common case that the table doesn't have a newindex metamethod to complete the write.	10 months ago
Roberto Ierusalimschy	3e9dbe143d	New function 'table.create' Creates a table preallocating memory. (It just exports to Lua the API function 'lua_createtable'.)	10 months ago
Roberto Ierusalimschy	4a8e480864	New mechanism to query GC parameters	10 months ago
Roberto Ierusalimschy	17e0c29d9b	Clear interface between references and predefines The reference system has a defined way to add initial values to the table where it operates.	10 months ago
Roberto Ierusalimschy	8eb0abc9db	Removed uses of LUA_NUMTAGS That constant was already deprecated (see commit `6aabf4b15e`).	10 months ago
Roberto Ierusalimschy	d862da6d04	Optimizations for 'lua_rawgeti' and 'lua_rawseti' 'lua_rawgeti' now uses "fast track"; 'lua_rawseti' still calls 'luaH_setint', but the latter was recoded to avoid extra overhead when writing to the array part after 'alimit'.	10 months ago
Roberto Ierusalimschy	e288c5a918	Bug: Yielding in a hook stops in the wrong instruction Yielding in a hook must decrease the program counter, because it already counted an instruction that, in the end, was not executed. However, that decrement should be done only when about to restart the thread. Otherwise, inspecting the thread with the debug library shows it one instruction behind of where it really is.	10 months ago
Roberto Ierusalimschy	7827c40c49	A few more tweaks in the garbage collector	10 months ago
Roberto Ierusalimschy	e7af9cdf0b	Fixed buffers reuse absolute line information	11 months ago
Roberto Ierusalimschy	12b6f610b0	Several tweaks in the garbage collector - back with step size in collectgarbage("step") - adjustments in defaults for some GC parameters - adjustments in 'luaO_codeparam'	11 months ago
Roberto Ierusalimschy	e81f586001	Removed compatibility option LUA_COMPAT_GCPARAMS The meaning of different GC parameters changed, so there is point in supporting old values for them. The new code simply ignores the parameters when changing the GC mode, so the incompatibility is small.	11 months ago
Roberto Ierusalimschy	e2cc179454	New option "setparms" for 'collectgarbage' The generational mode also uses the parameters for the incremental mode in its major collections, so it should be easy to change those parameters without having to change the GC mode.	11 months ago
Roberto Ierusalimschy	5853c37a83	Bug: Buffer overflow in string concatenation Even if the string fits in size_t, the whole size of the TString object can overflow when we add the header.	11 months ago
Roberto Ierusalimschy	ad0ea7813b	GC parameters encoded as floating-point bytes This encoding brings more precision and a larger range for these parameters.	11 months ago
Roberto Ierusalimschy	666e95a66d	Option 0 for step multiplier makes GC non-incremental	11 months ago
Roberto Ierusalimschy	4eda1acafa	Cleaner protocol between 'lua_dump' and writer function 'lua_dump' signals to the writer function the end of a dump, so that is has more freedom when using the stack.	11 months ago
Roberto Ierusalimschy	ad73b33224	Check minor->major made at the end of a minor cycle It does not make sense to wait for another cycle to decide when much of the information about creation of old objects is already available.	11 months ago
Roberto Ierusalimschy	925fe8a0f2	First criteria for shifts minor<->major	11 months ago
Roberto Ierusalimschy	789e7acdea	Major collections done incrementally Major collections do not need to "stop the world". Still pending: criteria for shifts minor-major, shifts generational-incremental.	11 months ago
Roberto Ierusalimschy	74b4013538	Removed macro 'changeage' It is simpler to use always 'setage'. The saving from 'changeage' is too irrelevant.	11 months ago
Roberto Ierusalimschy	b719ff9399	Removed parameter in 'collectgarbage("step")' A call to 'collectgarbage("step")' always performs one GC basic step.	11 months ago
Roberto Ierusalimschy	35a2fed2d1	Removed deprecated options in 'lua_gc' Options 'setpause' and 'setstepmul' were deprecated in Lua 5.4.	11 months ago
Roberto Ierusalimschy	63d68bd657	Comments detailing the ages for generational GC Plus other comments and small details.	11 months ago
Roberto Ierusalimschy	842a83f09c	Panic functions should not raise errors The standard panic function was using 'lua_tostring', which may raise a memory-allocation error if error value is a number.	12 months ago
Roberto Ierusalimschy	011850a8f8	Details in the manual	12 months ago
Roberto Ierusalimschy	52b899d60d	Simpler coding for new representation for arrays With the tags comming first in a cell, we can define the whole cell as a C type and let C do part of the address computations.	12 months ago
Roberto Ierusalimschy	25cd3d377e	Buffer in 'luai_makeseed' measured in bytes In the (rare) cases when sizeof(void*) or sizeof(time_t) are not multiples of sizeof(int), we still can use all their bytes in the seed.	12 months ago
Roberto Ierusalimschy	1028f296a8	Default paths stored as external strings	12 months ago
Roberto Ierusalimschy	6d042a178f	Auxiliary buffer uses external strings The buffer system from the auxiliary library reuses its buffer as external memory when closing long strings.	12 months ago
Roberto Ierusalimschy	eabf425c76	Correct anchoring and GC barriers in 'loadString' Call to 'luaH_setint' could call the GC with the string unanchored. Moreover, previously saved strings were being assigned to the prototype without a barrier.	12 months ago
Roberto Ierusalimschy	3b57e37e48	Fixed buffers save long strings as external.	1 year ago
Roberto Ierusalimschy	024f9064f1	External strings Strings can use external buffers to store their contents.	1 year ago
Roberto Ierusalimschy	7f4906f565	Towards external strings Long strings have a pointer to string contents.	1 year ago
Roberto Ierusalimschy	b8a9d14032	Details Comments and parameter name in header file.	1 year ago
Roberto Ierusalimschy	19afd91687	Solving merge issue with use of tables in dump/undump The use of tables in dump/undump to reuse strings did not exist in the version that changed the representation of arrays, so it was not corrected for the new API for tables.	1 year ago
Roberto Ierusalimschy	37c215b43f	Merge branch 'newarray' into nextversion	1 year ago
