2015-04-27Win32: shared memory base addresses and remapping.Maxim Dounin3-2/+84
Two mechanisms are implemented to make it possible to store pointers in shared memory on Windows, in particular on Windows Vista and later versions with ASLR: - The ngx_shm_remap() function added to allow remapping of a shared memory zone to the address originally used for it in the master process. While important, it doesn't solve the problem by itself as in many cases it's not possible to use the address because of conflicts with other allocations. - We now create mappings at the same address in all processes by starting mappings at predefined addresses normally unused by newborn processes. These two mechanisms combined allow to use shared memory on Windows almost without problems, including reloads. Based on the patch by Sergey Brester: http://mailman.nginx.org/pipermail/nginx-devel/2015-April/006836.html
2015-04-23Removed the "worker_rlimit_sigpending" directive.Ruslan Ermilov1-13/+0
It was only needed by the just removed rtsig module.

2015-03-20Removed busy locks.Ruslan Ermilov1-3/+0
2015-03-20Removed unix ngx_threaded and related ngx_process_changes.Ruslan Ermilov2-2/+0
2015-03-20Removed old pthread implementation.Ruslan Ermilov4-584/+0
2015-03-20Removed old FreeBSD rfork() thread implementation.Ruslan Ermilov5-965/+0
2015-03-14Added support for offloading Linux sendfile() in thread pools.Valentin Bartenev1-8/+183
2015-03-14Added support for offloading read() in thread pools.Valentin Bartenev2-0/+114
2015-03-14Thread pools implementation.Valentin Bartenev5-1/+384
2015-03-04Renamed NGX_THREADS to NGX_OLD_THREADS because of deprecation.Ruslan Ermilov4-12/+12
It's mostly dead code and the original idea of worker threads has been rejected.
2015-03-17Core: expose maximum values of time_t and ngx_int_t.Ruslan Ermilov1-0/+2
These are needed to detect overflows.
2015-02-27Refactored ngx_linux_sendfile_chain() even more.Valentin Bartenev1-46/+60
The code that calls sendfile() was cut into a separate function. This simplifies EINTR processing, yet is needed for the following changes that add threads support.
2015-02-11Refactored sendfile() AIO preload.Valentin Bartenev4-47/+112
This reduces layering violation and simplifies the logic of AIO preread, since it's now triggered by the send chain function itself without falling back to the copy filter. The context of AIO operation is now stored per file buffer, which makes it possible to properly handle cases when multiple buffers come from different locations, each with its own configuration.
2015-01-13Fixed sendfile() trailers on OS X (8e903522c17a, 1.7.8).Maxim Dounin1-0/+3
The trailer.count variable was not initialized if there was a header, resulting in "sendfile() failed (22: Invalid argument)" alerts on OS X if the "sendfile" directive was used. The bug was introduced in 8e903522c17a (1.7.8).
2014-12-24Fixed building with musl libc (ticket #685).Maxim Dounin1-0/+2
2014-11-19Style.Valentin Bartenev1-2/+2
2014-11-19Fixed type of sendfile() return value on Linux.Valentin Bartenev1-6/+6
There was no real problem since the amount of bytes can be sent is limited by NGX_SENDFILE_MAXSIZE to less than 2G. But that can be changed in the future
2014-08-13Moved writev() handling code to a separate function.Valentin Bartenev5-102/+60
This reduces code duplication and unifies debug logging of the writev() syscall among various send chain functions.
2014-08-13Merged conditions in the ngx_*_sendfile_chain() functions.Valentin Bartenev3-27/+10
No functional changes.
2014-08-13Moved the code for coalescing file buffers to a separate function.Valentin Bartenev3-72/+9
2014-11-19Refactored ngx_solaris_sendfilev_chain().Valentin Bartenev1-18/+7
Though ngx_solaris_sendfilev_chain() shouldn't suffer from the problem mentioned in d1bde5c3c5d2 since currently IOV_MAX on Solaris is 16, but this follows the change from 3d5717550371 in order to make the code look similar to other systems and potentially eliminates the problem in the future.
2014-10-07Introduced the ngx_output_chain_to_iovec() function.Valentin Bartenev5-318/+170
It deduplicates code of the send chain functions and uses only preallocated memory, which completely solves the problem mentioned in d1bde5c3c5d2.
2014-11-19Renamed ngx_handle_sent_chain() to ngx_chain_update_sent().Valentin Bartenev6-7/+7
No functional changes.
2014-08-13Events: introduced cancelable timers.Valentin Bartenev2-0/+4
2014-08-25Events: removed broken thread support from event timers.Valentin Bartenev1-1/+0
It's mostly dead code. And the idea of thread support for this task has been deprecated.
2014-10-15Win32: made build-able with MinGW-w64 gcc.Kouhei Sutou1-2/+35
2014-10-28Core: added limit to recv_chain().Roman Arutyunyan5-15/+41
2014-10-14Style.Maxim Dounin1-1/+2
2014-10-11Win32: suppressed warnings by "-Werror=sign-compare".Kouhei Sutou1-2/+2
2014-08-27Fixed counting of sent bytes in the send chain functions on EINTR.Valentin Bartenev5-0/+5
Previously, a value of the "send" variable wasn't properly adjusted in a rare case when syscall was interrupted by a signal. As a result, these functions could send less data than the limit allows.
2014-09-22Removed duplicate initialization of the "rev" variable.Valentin Bartenev1-2/+0
2014-08-13Generalized definitions of the number of preallocated iovec's.Valentin Bartenev7-57/+24
No functional changes.
2014-08-13Reduced difference between the send chain functions.Valentin Bartenev2-15/+11
No functional changes. This follows the change from ad137a80919f.
2014-08-13Merged implementations of ngx_readv_chain().Valentin Bartenev1-97/+9
There's no real need in two separate implementations, with and without kqueue support.
2014-08-13Removed the "complete" variable from various send chain functions.Valentin Bartenev6-42/+11
It was made redundant by the previous change, since the "sent" variable is no longer modified.
2014-08-13Moved the code for adjusting sent buffers in a separate function.Valentin Bartenev6-212/+7
2014-08-13Fixed writev() debug log message in ngx_darwin_sendfile_chain().Valentin Bartenev1-1/+1
2014-09-08Added ngx_init_setproctitle() return code check.Maxim Dounin2-3/+5
The ngx_init_setproctitle() function, as used on systems without setproctitle(3), may fail due to memory allocation errors, and therefore its return code needs to be checked. Reported by Markus Linnala.
2014-09-01Events: removed broken thread support from posted events.Valentin Bartenev2-12/+4
It's mostly dead code. And the idea of thread support for this task has been deprecated.
2014-08-01Core: exit on ngx_pnalloc() failure.Piotr Sikora1-0/+4
Signed-off-by: Piotr Sikora <piotr@cloudflare.com>
2014-08-03Style: use ngx_free() instead of free().Tatsuhiko Kubo1-1/+1
2014-07-28Bigger iovec buffer in ngx_readv_chain().Maxim Dounin1-1/+5
This helps to reduce likelyhood of memory allocations in ngx_readv_chain(), which are known to lead to noticeable effects in some cases, see http://mailman.nginx.org/pipermail/nginx/2014-July/044512.html.
