    Fix "tundra constantly rebuilds" bug due to uninitialized/garbage data

    …nitialized/garbage data.
    #36 changed so that C++ include scans are done into a hashset, which then is processed in
    hash order (to get stable ordering).
    However between scanning each input file, the scratch allocator was being reset, so for
    actions that had multiple input files (e.g. using precompiled header), the scans of
    the later ones trampled over some of the filenames in previous scan. The hashset
    processing was getting garbage filenames, and thus not adding their entries into
    digest cache.
    Now don't reset the scratch allocator between each input file scan; just around the loop
    that processes all of them. On Windows Standalone player build, max usage of
    temp scratch allocator increases from 210kb/thread to 225kb/thread on average, which sounds acceptable
    (temp allocator has 32MB capacity)

  1. ExecWin32: detect if lingering subprocess is keeping stdout/err file …

    kwi-dk committed Feb 19, 2019
    If that happens, it is a build program bug: Tundra already reported the
    output, so any further messages written to the file would disappear, or
    worse, be misattributed to another build action.
    The only way to consistently detect this is to close (and delete) the
    file, then attempt to recreate it. If this recreation fails, show a
    helpful error message and terminate the build.

  1. Make error handling more consistent

    kwi-dk committed Feb 19, 2019
    - Add the "missing" CroakErrnoAbort function, such that all Croak
      variations are now available.
    - Always report errno/GetLastError when system calls fail.
    - Also report Windows error codes in the more common hexadecimal form.
    - Use consistent "tundra: error: " heading for error message, ensuring
      the "reporter" is unambiguously identifiable in what may be a sea of
      messages from other programs (e.g. build automation or test suite).
  2. ExecWin32: on temp file creation error, abort sooner rather than later

    kwi-dk committed Feb 19, 2019
    Previously, the INVALID_HANDLE_VALUE would be passed to CreateProcessW,
    which would fail with ERROR_INVALID_PARAMETER, and then cause Tundra to
    abort. There's no reason to not simply fail immediately.
    Also, use CroakErrno to include the actual failure reason with the error
    message. (In my case, it was ERROR_SHARING_VIOLATION because of the file
    being kept open by a process lingering from a previous build action.)
  3. Manually flush C file streams before calling abort

    kwi-dk committed Feb 19, 2019
    The lack of flushing caused error messages to be swallowed on Windows.

  1. Add natvis file to the vcxproj file

    richard-fine committed Jan 4, 2019
    The natvis file was present on disk but not added to the vcxproj file, which meant that VS was not using it.
  2. Stable ordering + dedup for implicit inputs

    richard-fine committed Jan 4, 2019
    When collecting implicit inputs for a node's input signature, accumulate them in a hashset and then add them to the signature after scanning all explicit input files, rather than doing it on-the-fly. This allows us to ensure a stable ordering on the implicit inputs, as well as deduplicating them.
    Fix the way implicit inputs are recorded into the buildstate to also be deduplicated and stably ordered, to match.

    Shared Resources support

  1. Add missing files

    richard-fine committed Oct 10, 2018
  2. Shared Resources support

    richard-fine committed Oct 10, 2018
    Support for Shared Resources, which are logical entities which can be used by multiple build actions (e.g. compiler servers). A resource can run one command when it is created, and another when it is shut down. The first time we try to execute an action that needs a particular resource, the resource is created; and at the end of the build, all created resources are destroyed.
You can’t perform that action at this time.
