* nox/wide-chars/OTP-11088: Support wide characters in the shell through wcwidth() Fix bogus DEBUGLOG() incantations in ttsl_drv
2013-04-27Support wide characters in the shell through wcwidth()Anthony Ramine
There is one remaining bug where ttsl_drv's state ends up inconsistent with the terminal own state; when a wide character is entered on the last column of the terminal. Reported-by: Loïc Hoguin

2013-04-21fix valgrind error in erts/emulator/drivers/unix/ttsl_drv.cSteve Vinoski
Running some valgrind memory checking showed the error below: ==18040== Thread 6: ==18040== Source and destination overlap in memcpy(0xf3f3f04, 0xf3f3f08, 52) ==18040== at 0x4C2CFA0: memcpy@@GLIBC_2.14 (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==18040== by 0x5CF527: del_chars (ttsl_drv.c:845) ==18040== by 0x5CED5E: ttysl_from_erlang (ttsl_drv.c:658) ==18040== by 0x4982E3: erts_write_to_port (io.c:1235) ==18040== by 0x49A2BD: erts_port_command (io.c:2223) ==18040== by 0x48C054: do_send (bif.c:1962) ==18040== by 0x48CB6E: erl_send (bif.c:2162) ==18040== by 0x566599: process_main (beam_emu.c:1665) ==18040== by 0x4B1A95: sched_thread_func (erl_process.c:4834) ==18040== by 0x6075E2: thr_wrapper (ethread.c:106) ==18040== by 0x5560E99: start_thread (pthread_create.c:308) This occurred on Linux using R15B01 while the shell was emitting a prompt, but the same problem is still present in R16B. Change the memcpy on line 845 of ttsl_drv.c to memmove as valgrind suggests. After the change, verify with valgrind that the error no longer occurs.

2013-01-09Add file:allocate/3 operationFilipe David Manana
This operation allows pre-allocation of space for files. It succeeds only on systems that support such operation. The POSIX standard defines the optional system call posix_fallocate() to implement this feature. However, some systems implement more specific functions to accomplish the same operation. On Linux, if the more specific function fallocate() is implemented, it is used instead of posix_fallocate(), falling back to posix_fallocate() if the fallocate() call failed (it's only supported for the ext4, ocfs2, xfs and btrfs file systems at the moment). On Mac OS X it uses the specific fcntl() operation F_PREALLOCATE, falling back to posix_fallocate() if it's available (at the moment Mac OS X doesn't provide posix_fallocate()). On any other UNIX system, it uses posix_fallocate() if it's available. Any other system not providing this system call or any function to pre-allocate space for files, this operation always fails with the ENOTSUP POSIX error.

2012-11-02Fix oracle solaris bug in sendfileLukas Larsson
When using values of sfv_len and sfv_off which are larger than the file in question, sendfilev can sometimes return -1 and send data. It seems to be only Oracle SunOS which this happens on.

Thanks Tuncer Ayaz
2011-12-05Make solaris use sendfilevLukas Larsson
sendfilev is a richer API which allows us to do non blocking TCP on solaris. The normal sendfile API seems to have some issue with non blocking sockets and the return value of sendfile.
2011-12-02Use epoch seconds instead of datetime()Björn-Egil Dahlberg
First stage in utc-time for prim_file.
2011-12-02Remove header/trailer supportLukas Larsson
Since the API for headers/trailers seem to be very awkward to work with when using non-blocking io the feature is dropped for now. See unix_efile.c for more details.
2011-12-01Preliminary work on header/trailerLukas Larsson
Have to figure out how to represent progress in header writing when using non-blocking, not sure how to do this.
2011-12-01Remove debug printoutsLukas Larsson
2011-12-01Set chunk size to 3 GBLukas Larsson
It is not possible to use the maximum size_t/off_t for the chunks as that causes sendfile to return einval. 3GB seems to work on all *nix platforms.

2011-12-01Implement sendfile when there are no async threadsLukas Larsson
When there are no async threads sendfile will use the ready_output select on the socket fd to know when to send data. The file_desc will also be put in the sending sendfile_state which buffers all other commands to that file until the sendfile is done.
2011-12-01Implement blocking calls for sendfileLukas Larsson
Move sendfile data to invoke data instead of file_descr. Remove usage of ready_output when doing a send. If told to send 0 bytes, file_sendfile now sends the entire file for linux.
2011-12-01Implement sendfile using blocking io in asynch threadsLukas Larsson
Move the command handling to outputv in preparation for header and trailer inclusion in the sendfile api. Use the standard efile communication functions for sendfile.
2011-11-29Implement file:sendfileTuncer Ayaz
Allow Erlang code to use sendfile() where available by wrapping it as file:sendfile/4 and file:sendfile/2. sendfile(2) - Linux man page: "sendfile() copies data between one file descriptor and another. Because this copying is done within the kernel, sendfile() is more efficient than the combination of read(2) and write(2), which would require transferring data to and from user space."

2010-08-17erts: Remove stray pre-ISO-C compatibility macrosBjörn Gustavsson
A long time ago, the Erlang run-time system could be build with pre-ANSI/ISO-C (K&R) C compilers, but that is no longer possible. Remove the remaining uses of the compatibility macros that made it possible that possible.
