mORMot2 TSynAutoCreateFields multithreaded trouble

Vitaly · 2021-01-27 20:01:20

I have some multithreaded code, where each thread creates and uses TSynAutoCreateFields-based instances of the same types. All these threads are pre-initialized (so they start almost at the same time).
This code works ok with 1.18, but with 2.0 I occasionally get random errors (mostly AV), for example at TRttiCustom.SetAutoCreateFields. Could it be that somehow threads are getting mixed at TSynAutoCreateFields-based class registering?

If I add Create/Destroy procedures for these classes before multithreaded processing (in other words - pre-registering them in the main thread) - all goes fine:

  TKommuneInfoCountyGeo.Create.Free;
  TKommuneInfoMunicipalityGeo.Create.Free;

Indeed.

Should be fixed with https://github.com/synopse/mORMot2/comm … 8169ef0165
