Unzipping in the plugin crashing the browser

[Lindon]

So I have a download and unzip process defined inside my plugin;

first it down loads a set of files(zip files) to the users download folder)

then it goes thru and unzips these to locations on the users hard drive.

In HISE itself all works fine, in the compiled plugin in a DAW (Reaper) the download seems to work but then it crashes the DAW when we get to the unzip step....I mean really crashes the DAW - bang- gone...

Is there something obvious I'm doing wrong? Any one have experience with this?

@Lindon Sounds like a write permission type problem - are you on macOS?

[Lindon]

@d-healey hmm, this is happening on windows and macos.

[d.healey]

@Lindon Does it work in a standalone build? Let's rule out the DAW.

[Lindon]

@d-healey well its happening in every DAW - Reaper, Live, Waveform...

[d.healey]

@Lindon When we get to the debugger stage it will be easier if the problem is happening in a standalone build.

[Lindon]

@d-healey well tis looking more and more likely to be a file permissions thing...everything is working fine right up to the unzip command, how would I give the plugin permission to write to disk?

Meanwhile Im off to do this stand alone build...

[d.healey]

@Lindon You shouldn't need to do anything special, as long as it's writing to a place the user has permission to write to it should work. You can use File.hasWriteAccess() to check before attempting the write.

As a test try extracting everything to the downloads folder, if it crashes then it's probably not a permission issue.

Yep the stand alone is crashing when it gets to the unzipping part...

[d.healey]

@Lindon Good, we have an easier task of debugging. Now try extracting everything to a folder you know has write permission.

[Lindon]

@d-healey ok trying the user download folder

[Lindon]

@Lindon nope crash there too....

[d.healey]

@Lindon Aha so it's something more complicated. Can you share your download/extraction code with me?

[Lindon]

okay well more investigation and no resolution - I'm now a bit lost about what to do....

@Lindon did you make a debug standalone?

nope _ Im not entirely clear how I go about doing that...

@Lindon open the autogeneratedProject in your build folder so you can open the project in Xcode, then choose to build in Running rather than Profiling.

When it's built (it should say debug after the app name) run it, then make it crash and look at the crash report. Post findings here...

thanks well Im on windows but Im sure its similar...

[DanH]

@Lindon I guess, not so sure where the crash reports are and how readable they are...

yeah me neither - I'v opened projucer loaded the project into Visual Studio selected

Debug - started it - the app has opened, I've run it and its crashed (eventually) but I have no idea what im looking at now...
