Roberto Ierusalimschy	0593256707	'luaH_get' functions return tag of the result Undoing previous commit. Returning TValue increases code size without any visible gains. Returning the tag is a little simpler than returning a special code (HOK/HNOTFOUND) and the tag is useful by itself in some cases.	8 months ago
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	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	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	e7af9cdf0b	Fixed buffers reuse absolute line information	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	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	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	6baee9ef9d	Removed test for "corrupted binary dump" Test is too non portable. (For instance, it does not work for different number types.)	1 year ago
Roberto Ierusalimschy	14e416355f	Added suport for Fixed Buffers A fixed buffer keeps a binary chunk "forever", so that the program does not need to copy some of its parts when loading it.	1 year ago
Roberto Ierusalimschy	96f7714237	Field 'Proto.is_vararg' uses only one bit So that the other bits can be used for other purposes.	1 year ago
Roberto Ierusalimschy	0554581605	Opcode in dumps is stored properly aligned	1 year ago
Roberto Ierusalimschy	9b4f39ab14	More disciplined use of 'getstr' and 'tsslen' We may want to add other string variants in the future; this change documents better where the code may need to handle those variants.	1 year ago
Roberto Ierusalimschy	ab859fe59b	Bug: Loading a corrupted binary file can segfault The size of the list of upvalue names are stored separated from the size of the list of upvalues, but they share the same array.	2 years ago
Roberto Ierusalimschy	7d6a97e42b	Dump doesn't need to reuse 'source' All strings are being reused now, including 'source'.	2 years ago
Roberto Ierusalimschy	d70a0c91ad	Dump/undump reuse strings A repeated string in a dump is represented as an index to its first occurence, instead of another copy of the string.	2 years ago
Roberto Ierusalimschy	413a393e62	Stack indices changed to union's That will allow to change pointers to offsets while reallocating the stack.	2 years ago
Roberto Ierusalimschy	6bc0f13505	Fixed bug of long strings in binary chunks When "undumping" a long string, the function 'loadVector' can call the reader function, which can run the garbage collector, which can collect the string being read. So, the string must be anchored during the call to 'loadVector'.	4 years ago
Roberto Ierusalimschy	422ce50d2e	Fixed detail in 'loadUpvalues' In 'lundump.c', when loading the upvalues of a function, there can be a read error if the chunk is truncated. In that case, the creation of the error message can trigger an emergency collection while the prototype is still anchored. So, the prototype must be GC consistent before loading the upvales, which implies that it the 'name' fields must be filled with NULL before the reading.	4 years ago
Roberto Ierusalimschy	c33b1728ae	Details Added as incompatibility, in the manual, the extra return of 'io.lines'.	4 years ago
Roberto Ierusalimschy	6d7cd31fee	Fixed missing GC barriers in compiler and undump While building a new prototype, the GC needs barriers for every object (strings and nested prototypes) that is attached to the new prototype.	4 years ago
Roberto Ierusalimschy	61a4e64a66	Back to old encoding of versions in binary files (Undoing part of commit f53eabeed8.) It is better to keep this encoding stable, so that all Lua versions can read at least the version of a binary file.	5 years ago
Roberto Ierusalimschy	e8a52281d9	Code style in 'ldump'/'lundump'. - function names start with lower case; - state is always the first parameter.	5 years ago
Roberto Ierusalimschy	46c3587a6f	Clearer distinction between types and tags LUA_T* represents only types; tags (types + Variants) are represented by LUA_V* constants.	5 years ago
Roberto Ierusalimschy	5ff408d218	Changed internal representation of booleans Instead of an explicit value (field 'b'), true and false use different tag variants. This avoids reading an extra field and results in more direct code. (Most code that uses booleans needs to distinguish between true and false anyway.)	5 years ago
Roberto Ierusalimschy	f6aab3ec1f	First implementation of constant propagation Local constant variables initialized with compile-time constants are optimized away from the code.	5 years ago
Roberto Ierusalimschy	54f7b46c1e	New implementation for constants VLOCAL expressions keep a reference to their corresponding 'Vardesc', and 'Upvaldesc' (for upvalues) has a field 'ro' (read-only). So, it is easier to check whether a variable is read-only. The decoupling in VLOCAL between 'vidx' ('Vardesc' index) and 'sidx' (stack index) should also help the forthcoming implementation of compile-time constant propagation.	5 years ago
Roberto Ierusalimschy	ed2872cd3b	'require' returns where module was found The function 'require' returns the loader data as a second result. For file searchers, this data is the path where they found the module.	6 years ago
Roberto Ierusalimschy	f53eabeed8	Small changes in the header of binary files - LUAC_VERSION is equal to LUA_VERSION_NUM, and it is stored as an int. - 'sizeof(int)' and 'sizeof(size_t)' removed from the header, as the binary format does not depend on these sizes. (It uses its own serialization for unsigned integer values.)	6 years ago
Roberto Ierusalimschy	f99509581e	Removed extra information from RCS keyword strings Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.	6 years ago
Roberto Ierusalimschy	b397064955	avoid craches when loading tampered code with NULL as a string constant	7 years ago
Roberto Ierusalimschy	7622373033	using explicit tests for allocation overflow whenever possible	7 years ago
Roberto Ierusalimschy	dfd188ba12	detail (identation of switch)	7 years ago
Roberto Ierusalimschy	f96497397a	new type 'StackValue' for stack elements (we may want to put extra info there in the future)	7 years ago
Roberto Ierusalimschy	124bfd2081	dumping ints and size_ts compacted	7 years ago
Roberto Ierusalimschy	b42430fd3a	'lineinfo' in prototypes saved as differences instead of absolute values, so that the array can use bytes instead of ints, reducing its size. (A new array 'abslineinfo' is used when line differences do not fit in a byte.)	7 years ago
Roberto Ierusalimschy	8c1fb91802	macro 'incr_top' replaced by function 'luaD_inctop'. (It is not used in critical time pathes, can save a few bytes without the macro)	9 years ago
Roberto Ierusalimschy	ee5edb6b68	macros 'getaddrstr' and 'getstr' unified (they do the same thing)	9 years ago
Roberto Ierusalimschy	41964648ee	long strings are created directly in final position when possible (instead of using an auxiliar buffer to first create the string and then allocate the final string and copy result there)	9 years ago
Roberto Ierusalimschy	28fdbcf393	added include for 'lprefix.h', for stuff that must be added before any other header file	10 years ago
Roberto Ierusalimschy	89b56e7d84	more precision between closure types ('LClosure' x 'CClosure')	11 years ago
Roberto Ierusalimschy	7021cc9bc8	allows different 'source' for each prototype, but inherits it from parent when they are equal (only possible case for chunks created by the parser)	11 years ago
Roberto Ierusalimschy	94266dfdbd	source for all prototypes must be equal in a chunk; no need to store each one separated	11 years ago
Roberto Ierusalimschy	ffa43df3cd	'setnvalue' -> 'setfltvalue' (for consitency with 'fltvalue')	11 years ago
Roberto Ierusalimschy	607be77ec8	some details to avoid warnings	11 years ago
Roberto Ierusalimschy	420cc62fac	missplelling in comments/function names (endianess -> endianness)	11 years ago
Roberto Ierusalimschy	80fe8504f5	make all dumps/loads go trhough Load/DumpVector (so it is easier to adapt the code to correct endianess, if needed)	11 years ago
Roberto Ierusalimschy	e976384213	keep chunk's headers compatible at least up to LUAC_VERSION (to be able to detect correctly version mismatches)	11 years ago
Roberto Ierusalimschy	901da539e5	no need to avoid negative ints in 'LoadInt'	11 years ago
