      Fuzzy a bit more the detection of timeouts by 0.1 second. · 190b5286
      Guillaume Melquiond authored
      The formula now matches the one for detecting variations on Unknown
      answers. This commit also restores the time limit for Metis, since its
      removal simply caused Metis to be killed just as early by the operating
      Theoretically, all the provers suffer from this issue, so it is kind of
      a mystery why Metis is the only prover to be killed so early. I guess
      the value of ru_utime is not reliable for Metis.

      Handle signal information in the client. · 87de7944
      Guillaume Melquiond authored
      The server was properly detecting that a prover had been killed by a
      signal, but the client was ignoring this information and was just assuming
      that the client had exited normally. Now the client properly marks the
      prover as killed by a signal. Also, the server now transmits the signal
      number on Linux (that was already the case on Windows).

      Add debug keep_vcs: allow to use a given filename to save prover files. · 979cf05c
      Sylvain Dailler authored
      It is now possible to give an optional argument to schedule_proof_attempt
      so that (when in debug mode) the file given is used to store the generated
      input file of the prover. In non debug mode, the file given to
      schedule_proof_attempt is used but removed after the call to the prover.
      Currently, no file is ever given to schedule_proof_attempt but this can be
      used by people using Why3 as a backend.

      Using new forward_result to get new results from why3server. · d1c876ec
      Sylvain Dailler authored
      Changing the structure of timeout_handler which now uses one hashtable
      with the prover calls information and one queue which has the editor call
      The loop in timeout_handler is now done on the result given by why3server
      not on a queue of prover task. This is more efficient and the code should
      be the same even when blocking = true.

      P909-002 allow for large exit codes · 883af7f6
      Johannes Kanig authored
      Sometimes the windows syscall GetExitCodeProcess returns a large result,
      larger than the ocaml [int] type. This is expected and not an error. For
      example the constant STATUS_QUOTA_EXCEEDED, which is 0xC0000044, may be
      a valid exit code. Such large values trip up the [int_of_string] parsing
      in the client.
      This patch implements the following solution to this problem:
      * the server doesn't care and sends the large value;
      * (the server now recognizes this value, though, to set the timeout flag
        more often)
      * the client uses an Int64 value to parse that big constant;
      * when converting to the internal Unix.process_status type, we simply
        convert to [int], because such large values don't have any special
        meaning for Why3 anyway.
      * call_provers.ml
      (parse_prover_run): now directly take the exit status as argument, and
      convert it to int;
      (handle_answer): don't wrap argument to parse_prover_run into unix type
      * prove_client.ml
      (read_answer): read Int64 type now
      * server-win.c
      (handle_child_event): set timeout boolean also when exitcode is equal to
         constant STATUS_QUOTA_EXCEEDED

      Yet another attempt to fix unstability of prover answers · 32c8a24c
      MARCHE Claude authored
      - Call_provers.parse_prover_run does not attempt fixing answer anymore,
        except in the case where the answer is HighFailure and time is close
        to time limit (which is considered as Timeout)
      - Session_scheduler.fuzzy_proof_time is now more liberal, accepts
        that two answers Unknown or Timeout of OutOfMemory with less than
        10% difference in time are equivalent, and thus should not be
        reported as a significant change

      P509-017 fix incorrect time limits · 34f472e9
      Johannes Kanig authored
      The adaptation of time limits was incorrect, and could transform "0" (no
      time limit) to "1" (second).
      * call_provers.ml
      (adapt_limit): do nothing when no time limit was present

      Call_provers: simplify API · 8159c0d7
      Andrei Paskevich authored
      - drop closures "pre_prover_call" and "post_prover_call". They were
        intended to be used for synchronous interaction with provers from
        multiple threads. This is now responsibility of the proof server:
        (a) any Call_prover.call_on_[file|buffer] submits the proof task
            immediately to the server;
        (b) all proof results are handled in the working Why3 thread.
      - Call_provers.query_call returns a tri-state "prover_update" type
        which can be one of: "ProverStarted" (returned after the proof
        server informs Why3 that a prover was started), "ProverFinished"
        (returned after the proof server returns the prover result), and
        "NoUpdates" (returned when the proof server has not sent any new
        updates concerning the proof task in question).
          IMPORTANT: query_call does not maintain the state of a given
        prover call. In a normal use case, "ProverFinished" is returned
        _exactly_ once, and "ProverStarted" _at_most_ once (never for
        an editor call or when rapidly overwritten by "ProverFinished").
          TODO: extend the proof server protocol and implementation to
        send "ProverStarted" events back to Why3.

      Prove_client: change the "standalone" logic · 39ed26b1
      Andrei Paskevich authored
      1. No default socket name is provided. If Why3 should connect to
         an external server, Prove_client.set_socket_name must be called
      2. If Prove_client.set_socket_name was never called, Why3 assumes
         to be in the stand-alone mode, and will start the server in the
         standard tmp directory (on Unix, $TMPDIR or /tmp, on Win, $TEMP or .).
         The socket name is set to be "why3server.<PID_of_Why3>.sock",
         to avoid clashes with other Why3 processes (fixes the Coq tactic).
      3. Global reference Prove_client.standalone is removed.
      4. Call_provers does not reexport Prove_client.set_socket_name.
      5. Prove_client.connect does nothing if the socket reference is set.

      we need to compare the running time with the time limit as seen
