in reply to communication between server/client

Two common problems with client-server programming are

  • using readline (<$socket>) to read data, but not writing newlines on the other end
  • not having made sure data is actually being sent (without buffering), by either calling IO::Handle's ->autoflush() (once) or ->flush() (after every write operation) on the respective handle

A cursory scan of your code seems to suggest that at least one of those problems is involved.

[choroba]: (well, it comes from the 14th century, so labelling it as "modern" doesn't seem appropriate)
[Your Mother]: "They" is becoming accepted but it irritates me sometimes. I tend to just pick she or he randomly or try to use "one."
LanX thinks it is appropriate here :)
[Your Mother]: They would think so.
[jdporter]: ok, I need a recipe for piping lines "through" an external program which is itself a filter
[jdporter]: without using a tmp file
[1nickt]: tobyink perl -MTypes::Standard= is_Int -Mstrict -wE 'say 1 if is_Int 1.0'
[jdporter]: so that I can use the existing expand unix util. Otherwise, I'll probably use Text::Tabs.
[1nickt]: pryrt I guess I don;t really care if user 42 logs on as 42.0 ... more of an academic question at this point.
[LanX]: jdporter: open PIPE,'-|' ?
