* util.pposix: Bind isatty(3)Kim Alvefur2021-07-041-0/+9
| | | | | Useful for disabling certain behavior, ANSI colors etc when not connected to a terminal.

| * util.strbitop: Remove redundant init functionKim Alvefur2020-10-151-4/+0
| | | | | | | | | | When you have 3 almost identical functions, you tend to edit one and then copypaste. Forgot to remove this line from the other two.

| * util.strbitop: Create buffer in the correct size (optimization)Kim Alvefur2020-10-151-6/+13
| | | | | | | | | | This avoids dynamically growing the buffer as Lua does when luaL_addchar is used, thus saving on realloc calls.

* | configure: Pass compiler flag to enable ICU only when building util.encodingsKim Alvefur2020-07-122-0/+3
| | | | | | | | Passing it in CFLAGS applied to all modules, which was not needed.

| | | | | | | | | | | | | | failure conditions Actually just an alias of pushnil, but it does make it more obvious where the failure conditions are, which is good for readability.
* | util.ringbuffer: Add :sub() and :byte() methods equivalent to the string methodsMatthew Wild2020-06-041-1/+102
| |
* | util.ringbuffer: Prevent creation of buffer with negative sizeKim Alvefur2020-06-041-1/+1
| | | | | | | | | | Previously this would have been (unsigned)-1 which is a large positive integer.
* | util.ringbuffer: Prevent creation of zero-size bufferKim Alvefur2020-05-291-0/+1

* | util.pposix,signal: Pass around various OS numbers as integers [Lua 5.3]Kim Alvefur2020-05-042-28/+34
| | | | | | | | | | | | | | Passing around PIDs, UIDs etc as integers makes it more sane in Lua 5.3. Getting 1234.0 as PID is silly. Shouldn't change any behavior as these are all integers on the C side and the integral floats are accepted as integers when passed back from Lua into C.
* | util.hashes: Fix output length of PBKDF2-HMAC-SHA256Kim Alvefur2020-04-221-1/+1
| | | | | | | | Somehow it got SHA1's 20 byte output instead of the proper 32 = 256/8
* | util.net: Fix signedness warning on ARMEmmanuel Gil Peyrot2020-01-301-2/+2
| | | | | | | | net.c:87:56: warning: comparison of integer expressions of different signedness: ‘long unsigned int’ and ‘long int’ [-Wsign-compare]

| | | | | | | | | | If you manage to pass a table or something weird to these, you deserve to know.
| * util.encodings: Strictly verify that the 'strict' *prep argument is a booleanKim Alvefur2019-10-301-4/+10
| | | | | | | | | | This is to prevent mistakes like nodeprep(username:gsub("a","b")) from unintentionally invoking strict mode.

| * util.poll: Add missing return statements in fallback modeKim Alvefur2019-07-281-0/+2
| | | | | | | | | | | | | | These allowed modifying or deleting select() state for unregistered FDs. During normal usage this should never happen. Modifying one that isn't set might cause weirdness but deleting an already deleted FD isn't a problem.
