321 | * Frontend server logic.
|
---|
322 | *
|
---|
323 | * This code receives incoming APDUs, and handles client requests by means
|
---|
324 | * of the backend API.
|
---|
325 | *
|
---|
326 | * Some of the code is getting quite involved, compared to simpler servers -
|
---|
327 | * primarily because it is asynchronous both in the communication with
|
---|
328 | * the user and the backend. We think the complexity will pay off in
|
---|
329 | * the form of greater flexibility when more asynchronous facilities
|
---|
330 | * are implemented.
|
---|
331 | *
|
---|
332 | * Memory management has become somewhat involved. In the simple case, where
|
---|
333 | * only one PDU is pending at a time, it will simply reuse the same memory,
|
---|
334 | * once it has found its working size. When we enable multiple concurrent
|
---|
335 | * operations, perhaps even with multiple parallel calls to the backend, it
|
---|
336 | * will maintain a pool of buffers for encoding and decoding, trying to
|
---|
337 | * minimize memory allocation/deallocation during normal operation.
|
---|
338 | *
|
---|
339 | * TODOs include (and will be done in order of public interest):
|
---|
340 | *
|
---|
341 | * Support for EXPLAIN - provide simple meta-database system.
|
---|
342 | * Support for access control.
|
---|
343 | * Support for resource control.
|
---|
344 | * Support for extended services - primarily Item Order.
|
---|
345 | * Rest of Z39.50-1994
