Re: [Twisted-Python] sharing a dict between child processes

If you need guaranteed delivery of the data, why not just use a TCP connection to the unix socket, instead of a UDP connection which inherently can lose data? In that case I don't think your patch would be needed. I didn't look at the source, so perhaps I missed something. On Wed, Nov 6, 2019 at

Thanks for the info. Yeah, it seems that UDS is the way to go. (I need to read more about them). Actually, is there a simple example you can give that can help me understand this a bit better? Thanks On Wed, Nov 6, 2019 at 9:07 AM Scott, Barry wrote: > On Wednesday, 6 November 2019 16:43:52 GMT

Re: [Twisted-Python] sharing a dict between child processes

Hi Barry, Thanks for the response. Where can I read more about (1). It seems like that is something I need to explore. As we already have (2) (cache for each process). Thanks again for your help. On Wed, Nov 6, 2019 at 8:39 AM Scott, Barry wrote: > On Wednesday, 6 November 2019 14:21:22

Re: [Twisted-Python] sharing a dict between child processes

Hi Marteen, Thanks for the response. When you say "when one process mutates the dictionary while another is looking up something or also mutating it." Do you mean that a key/value pair is getting modified or is it that a dict, in general, is getting modified. The first one is not really a concer

[Twisted-Python] sharing a dict between child processes

Hi, So, I am writing a twisted server. This server spawn multiple child processes using reactor spawnProcess that initializes a process protocol. Now, each of the childprocess receives some REST requests. Each process has a dict that acts as cache. Now, I want to share dict across processes. In ge
