Roberto Ierusalimschy faaf7e481f Removed use of 'rl_inhibit_completion' in 'lua.c' 
Some old systems (e.g., Mac OS X 10.4) do not define
'rl_inhibit_completion', even when line history is available.
Anyway, the user can configure this option externally, using '~/.inputrc'.

Roberto Ierusalimschy 3d838f635c Added "emergency collection" to 'io.tmpfile' and 'os.tmpname' 
These operations also can give errors for lack of resources, so they
also will try "emergency collections" in case of resource errors.
Because there are now two libraries with that kind of handling,
'resourcetryagain' was moved to the auxiliary library to be shared
by the libraries.

Roberto Ierusalimschy aa4c5cf190 Added directory to test file names in '$Id:' 
From the point of view of 'git', all names are relative to the root
directory of the project. So, file names in '$Id:' also should be
relative to that directory: the proper name for test file 'all.lua'
is 'testes/all.lua'.

Roberto Ierusalimschy b47f2cd068 Small improvements in the manual 2018-07-25 14:56:42 -03:00
Roberto Ierusalimschy e885dee5ab File operations try an "emergency collection" when failing 
If a file operation fails do to lack of resources (too many open
files or not enough memory), it does a full garbage collection and
tries the operation again. Lack of resources are "too many open
files" (process wise and system wise) and "not enough memory".
The code is full of '#if's because error codes are not part
of the standard ISO C.

Roberto Ierusalimschy ccae0f5aad Comments about OLD0/OLD1 ages 
Improved the comments in file 'lgc.c' explaining the roles of "ages"
OLD0 and OLD1 in the generacional collector.

Roberto Ierusalimschy 2e297d6ab3 Fixed bug in generational collection of userdata 
During generational collection, a userdatum must become gray and
go to a gray list after being traversed (like tables), so that
'correctgraylist' can handle it to its next stage.

This commit also added minimum tests for the generational collector,
including one that would detect this bug.

Roberto Ierusalimschy fb18346ddd Avoid using 'int' for UTF-8 values 
An 'int' may have only 16 bits, so it may not be big enough for UTF-8
values. The new type 'utfint' (in the utf8 library) ensures at least
21 bits for those values.

Roberto Ierusalimschy 96f9643f33 Bug: wrong 'nCcalls' when resuming a coroutine 
The counter 'nCcalls' now includes the number of CallInfo structures
pre-allocated (so that these "potential" C calls can be made without
checking 'nCcalls'). So, when copying this value from a thread to
another, in 'lua_resume', it must be corrected to the number of
CallInfo structures in the thread being resumed.

Roberto Ierusalimschy 84058b1506 Added definition for LUA_VERSION_RELEASE_NUM 
LUA_VERSION_RELEASE_NUM is set to the release number of the Lua
interpreter (e.g., 5.4.0 becomes the integer 50400).
 2018-07-11 13:17:46 -03:00
Roberto Ierusalimschy 4d5de1c1fb Fixed bug in line info. when using 'not' operator 
When creating code for a jump on a 'not' condition, the code generator
was removing an instruction (the OP_NOT) without adjusting its
corresponding line information.

This fix also added tests for this case and extra functionality in
the test library to debug line info. structures.

Roberto Ierusalimschy 941b189d98 Improvements in the manual 
- More precise use of 'argument' x 'parameter'.
- Clarification about what the lexer considers 'letter', 'space',
and 'digit'.

Roberto Ierusalimschy 626cf0581b Generational mode may wait longer after a major collection 
When Lua is building large long-duration structures, frequent small
minor collections just waste time. Trying to avoid this, the
collector will do a larger pause after a major collection when it
does not collect enough garbage (which is a hint that memory is
being used for long-lasting objects).
 2018-07-09 14:22:09 -03:00
Roberto Ierusalimschy ccf6d098f6 'searchpath' creates less temporary strings 
When creating error messages, package loaders may create dozens of
temporary strings (one or more for each tried template). This change
reduces the number of these strings, and avoid creating some of
them if the search is successful.

Roberto Ierusalimschy de2caf7ee4 Bit-library file removed from the project (as it was deprecated) 
This commit only removed the file 'lbitlib.c' from the project; the
makefile already was not using it.
 2018-07-09 12:54:51 -03:00
Roberto Ierusalimschy b08c9079c5 Opcode names moved to a new header file 
The array with the names of the opcodes was moved to a header file
('lopnames.h'), as it is not used by the Lua kernel. Files that need
that array ('luac.c' and 'ltests.c') include the header file to get
a private (static) copy.

Roberto Ierusalimschy 06e08c6d05 Fixed bug in OP_IDIVI

'luai_numidiv' (integer division).
