startup_hacks() called SetErrorMode() with the SEM_NOGPFAULTERRORBOX argument to prevent GUI popups on error. While that likely was sufficient at some point, there are other sources of error popups. At the same time SEM_NOGPFAULTERRORBOX unfortunately also prevents "just-in-time debuggers" from working reliably, i.e. the ability to attach to a process on crash. This prevents collecting crash dumps as part of CI. The error popups are particularly problematic when they occur during automated testing, as they can cause the tests to hang, waiting for a button to be clicked. This commit improves the error handling setup in startup_hacks() to address those problems. SEM_NOGPFAULTERRORBOX is not used anymore, instead various other APIs are used to disable popups and to redirect output to stderr where possible. While this improves the situation for postgres.exe, it doesn't address similar issues in all the other executables. There currently is no codepath that's called early on for all frontend programs. I've tested that this prevents GUI popups and allows JIT debugging in case of crashes due to: - abort() - assert() - C runtime errors - unhandled exceptions both in debug and non-debug mode, on Win10 with MSVC 2019 and with MinGW. Now that crash reports are generated on windows, collect them in windows CI. Discussion: https://postgr.es/m/20211005193033.tg4pqswgvu3hcolm@alap3.anarazel.de |

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
