pleonex / xdelta-sharp Goto Github PK

Recent versions of xdelta3 apply some sort of secondary compression by default. xdelta-sharp clearly does not support this (throws exception about secondary compressor). I've spent couple hours fighting this issue, so i'm sharing my workaround for anyone who might be struggling with it.

Issue can be avoided by using -S argument of xdelta3 to disable secondary compression:

xdelta3 -e -S -s original_file modified_file output_patch

Might be worth mentioning in docs or in exception message itself?

i opened both xdeltasharp and create dump and both of them open and then close automaticly

I was trying to patch a large file (4 448 220 211 bytes) with not so large xdelta, and it failed. Worth mentioning in limitations list i guess. By the way, any thoughts if it's difficult to support large files?

As part of the release process, we should publish a NuGet package to nuget.org
This should be done after merging the branch changing the namespaces.
