Recent monitor.rb has performance problem because of interrupt
handlers. 'Monitor#synchronize' is frequently used primitive
so the performance of this method is important.
This patch rewrite 'monitor.rb' with 'monitor.so' (C-extension)
and make it faster. See [Feature #16255] for details.
Monitor class objects are normal object which include MonitorMixin.
This patch introduce a Monitor class which is implemented on C
and MonitorMixin uses Monitor object as re-entrant (recursive)
Mutex. This technique improve performance because we don't need
to care atomicity and we don't need accesses to instance variables
any more on Monitor class.
The function getwch() returns some key sequences which start from 0 or 0xE0
with a following key code. Alt+` that is on/off key for input methods gives 0
and 41 so Reline was always ignoring 0 and following keys but numeric keypad
keys give 0 and following actual keys. This commit changes the behavior to be
ignoring only the 0 and 41 sequence.
My previous fix in d0ed935d5b was
not correct, as pointed out by cremno on GitHub.
This simplifies things by just using Kernel#to_s. Also switch to
bind_call(obj) instead of bind(obj).call for better performance.
This rescues some exceptions that could happen with a closed or
shutdown DRb socket. This can prevent the server from
exiting if an client socket is closed directly after it is
accepted.
Fixes [Bug #8039]
This makes it so that client instances that call a method on a
server-side object that raise a subclass of Exception are handled
similarly to those that raise a subclass of StandardError.
Only reraise exceptions that we are fairly sure we don't want to
rescue.
Fixes [Bug #5618]
* Handle BasicObject in drb
Also fix a bug in rescue clause of any_to_s because sprintf
does not handle the %l modifier.
Fixes [Bug #7833]
* Do not send a reply to the client if there is a connection error
This allows for normal TCP shutdown (fin-ack-fin-ack instead of
fin-ack-push-rst).
Patch from pierre@mouraf.org (Pierre-Alexandre Meyer).
Fixes [Bug #2339]
* Detect fork and do not reuse forked connections in drb
This associates each DRbConn with a pid, and if the pid changes,
it closes any DRbConns in the pool with a pid that no longer
matches. This fixes DRb servers from sending messages intended
for one client to another client after forking.
Fixes [Bug #2718]
Fixes [Bug #14471]
For BasicObject, bind the Kernel respond_to? instance method to the
object and call it instead of calling the method directly.
Also, use bind_call(recv, ...) for better performance.
Fixes [Bug #16127]
