2017-09-05Replace the zlib driver with a NIFJohn Högberg
All operations will now yield appropriately, allowing them to be used freely in concurrent applications. This commit also deprecates the functions listed below, although they won't raise deprecation warnings until OTP 21: zlib:adler32 zlib:crc32 zlib:inflateChunk zlib:getBufSize zlib:setBufSize The behavior of throwing an error when a dictionary is required for decompression has also been deprecated.

2017-06-14Mark socket disconnected on tcp_send_or_shutdown_errorkvakvs
The socket left lingering due to {exit_on_close, false} will accept writes in a confusing way, returning either enotconn or blocking. This fix allows socket to know that it has been closed recently, and new writes won't pass.

This fixes a bug where a send/shutdown error on an active-mode socket results in the port never being properly closed.

2016-02-24erts: Change erl_exit into erts_exitSverker Eriksson
This is mostly a pure refactoring. Except for the buggy cases when calling erlang:halt() with a positive integer in the range -(INT_MIN+2) to -INT_MIN that got confused with ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT. Outcome OLD erl_exit(n, ) NEW erts_exit(n, ) ------- ------------------- ------------------------------------------- exit(Status) n = -Status <= 0 n = Status >= 0 crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0 The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and ERTS_DUMP_EXIT are the same as before (even though their values have changed).

2016-01-12Assign externally open fd to gen_tcp (UDS support)Serge Aleynikov
When a AF_LOCAL file descriptor is created externally (e.g. Unix Domain Socket) and passed to `gen_tcp:listen(0, [{fd, FD}])`, the implementation incorrectly assigned the address family to be equal to `inet`, which in the inet_drv driver translated to AF_INET instead of AF_LOCAL (or AF_UNIX), and an `einval` error code was returned. This patch fixes this problem such that the file descriptors of the `local` address family are supported in the inet:fdopen/5, gen_tcp:connect/3, gen_tcp:listen/2, gen_udp:open/2 calls
2015-12-20efile_drv: logic error in compressed file writeMikael Pettersson
Compiling OTP 18.2.1 with gcc-5.3 shows the following warning: drivers/common/efile_drv.c:1538:23: warning: logical not is only applied to the left hand side of comparison [-Wlogical-not-parentheses] The code in question is: if (! (status = erts_gzwrite((ErtsGzFile)d->fd, iov[i].iov_base, iov[i].iov_len)) == iov[i].iov_len) { d->errInfo.posix_errno = d->errInfo.os_errno = errno; /* XXX Correct? */ break; } If we hoist the assignment out of the if for clarity, it becomes: status = erts_gzwrite(..., iov[i].iov_len); if (! status == iov[i].iov_len) { ...; break; } iov_len is > 0 here, and status will equal iov_len if erts_gzwrite succeeded, but will be less than iov_len if an error occurred. "! status" is 0 or 1, which can only equal iov_len if iov_len is 1 and erts_gzwrite detected an error and returned 0. The effect of this mistake is that any error when iov_len >= 2 will skip the conditional code and break statement. In particular, partial writes (0 < status && status < iov_len) will not be flagged as errors. All releases since OTP R8B-0 are affected. The variable "status" is really a boolean, which is to be set to zero on error. The fix is to set status to 1 if erts_gzwrite() returned iov_len and 0 otherwise, and to change the condition to "if (! status) ...". I'm also hoisting the assignment out of the condition since it obscures the code while providing not benefit (the condition in a while or for loop would be a different matter).
