Plugin crahes 4Dv13hotfix3 at quit #2

Open Wojog opened 9 years ago

Wojog commented 9 years ago

Hello, when quiting or restarting 4Dv13 solution with latest version of html converter plugin, 4D crashes. Without plugin no problem. any idea what can be the cause (WIN 8 64 bit PC) Kind regards, Luc Vanoppen

the library is not really written to be used as a plugin: there is a de-init API, wkhtmltopdf_deinit and wkhtmltoimage_deinit, which is only meant to be called once per process (application).

when you close a 4DB, the plugin is unloaded, but the process (4D) is still running, and opening/closing another (or the same) 4DB forces you you de-init for the second time, which crashes the library.

the only solution seems to be to NOT de-init the library at all.

B.T.W. a new version is available at https://github.com/miyako/4d-plugin-HTMLTOX

Miyako, Thanks for the info and update. I have downloaded the HTMLTOX plugin demo database, but when opening in version 15 (I skipped version 14) 4D crashes. Also when adding the plugin to a new v15 database, 4D crashes on opening the database. Kind regards, Luc Vanoppen

Hello,

for your information, I can open and run the sample DB on v15/El Capitan, I also have a user (on 4D forums) reporting good results, so it seems unlikely to be a universal problem.
