* 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]

* util.encodings: Don’t export unneeded symbolsEmmanuel Gil Peyrot2019-12-011-8/+8
| | | | This reduces the binary size from 22704 B to 18592 B.

| * util.encodings: Don't ignore non-strings passed to stringprep functionsKim Alvefur2019-11-021-11/+1
| | | | | | | | | | 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.encodings: Optional strict flag to stringprepKim Alvefur2019-04-241-2/+14

| * util.encodings: Spell out all IDNA 2008 options ICU hasKim Alvefur2019-09-111-1/+24

| * util.encodings: Switch ICU binding to IDNA2008 (fixes #533, #1301)Kim Alvefur2019-09-111-4/+9
| |
| * 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.
| * util.encodings: Declare absence of arguments [-Wstrict-prototypes]Kim Alvefur2019-05-131-1/+1

|
* util.poll: Early return from __gc in case of no valid epoll FDKim Alvefur2018-10-111-0/+4
| | | | | This could happen if the epoll FD has already been closed or the epoll_create call failed
* util.poll: Increase max epoll events per callKim Alvefur2018-10-081-1/+1
| | | | | | | | | | This makes the struct roughly the same size in both epoll and select mode (64bit). There doesn’t seem to be much guidance on an appropriate size, it does not seem to matter too much since if there are more events they will simply show up in the next epoll_wait call. The number of exactly concurrent events should be fairly low most of the time anyways.
* util.poll: Zero FD sets watched for errors on creationKim Alvefur2018-10-071-0/+2

|
* util.poll: Fix monitoring of socket exceptions in select modeKim Alvefur2018-10-061-1/+1
| | | | | Since state->err is a set of all watched FDs, this mistake caused all sockets to appear to have errors.
