lua/lundump.c, branch v5.4.9A mirror of https://github.com/lua/lua
https://git.lua4.win/lua/atom?h=v5.4.92023-09-08T19:19:21+00:00Removed test for "corrupted binary dump"2023-09-08T19:19:21+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-09-08T19:19:21+00:00urn:sha1:6baee9ef9d5657ab582c8a4b9f885ec58ed502d0
Test is too non portable. (For instance, it does not work for
different number types.)
More disciplined use of 'getstr' and 'tsslen'2023-08-17T18:59:28+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-08-17T18:59:28+00:00urn:sha1:9b4f39ab14fb2e55345c3d23537d129dac23b091
We may want to add other string variants in the future; this change
documents better where the code may need to handle those variants.
Bug: Loading a corrupted binary file can segfault2023-03-17T18:52:09+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-03-17T18:52:09+00:00urn:sha1:ab859fe59b464a038a45552921cb2b23892343af
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.
Stack indices changed to union's2022-10-29T15:06:37+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-10-29T15:06:37+00:00urn:sha1:413a393e6222482f46599e138bebac162610a572
That will allow to change pointers to offsets while reallocating
the stack.
Fixed bug of long strings in binary chunks2020-08-18T17:42:11+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2020-08-18T17:42:11+00:00urn:sha1:6bc0f13505bf5d4f613d725fe008c79e72f83ddf
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'.
Fixed detail in 'loadUpvalues'2020-06-30T18:36:26+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2020-06-30T18:36:26+00:00urn:sha1:422ce50d2e8856ed789d1359c673122dbb0088ea
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.
Details2020-06-18T14:07:27+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2020-06-18T14:07:27+00:00urn:sha1:c33b1728aeb7dfeec4013562660e07d32697aa6b
Added as incompatibility, in the manual, the extra return of 'io.lines'.
Fixed missing GC barriers in compiler and undump2020-06-16T12:54:20+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2020-06-16T12:54:20+00:00urn:sha1:6d7cd31feec58011a593cf732274a33dcc1bcb53
While building a new prototype, the GC needs barriers for every object
(strings and nested prototypes) that is attached to the new prototype.
Back to old encoding of versions in binary files2020-05-06T17:19:08+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2020-05-06T17:19:08+00:00urn:sha1:61a4e64a6667bedaa882571c48a173ef5a4ba73b
(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.
Code style in 'ldump'/'lundump'.2020-02-27T18:17:44+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2020-02-27T18:17:44+00:00urn:sha1:e8a52281d9cba1c8dd49a06e7523d7e39794ecc1
- function names start with lower case;
- state is always the first parameter.
