As a second step improving unrolled#90, only lock when absolutely necessary and reconstruct functions to ensure that the current templates are referenced in the helper func instead of a global reference. Closes unrolled#91 Signed-off-by: Andrew Thornton <[email protected]>
If setting IsDevelopment, if we can, use an FsWatcher to recompile the templates in a separate goroutine. This should definitely increase the performance of the Development server. In order to make Asset based Renders have the same improvement - now that render compilation properly locks the templates we can expose the CompileTemplates function and allow downstream users to call this independently when their templates need recompilation.

Do we need the lock to read r.hasWatcher? Looks like it's only set within the CompileTemplates func.

@zeripath Looking again, the lock is probably a good idea since CompileTemplates is now exposed.

Sorry I didn't get round to replying re: this - yes that was the reasoning.

If we have set
Options.IsDevelopment, if we can, use anfsnotify.Watcherto recompile the templates in a separate goroutine. This will significantly increase the performance of the Development server only recompiling if there is a change to the template files instead of recompiling on every request.This will work well for renderers using the directory format however, if
Options.AssetorOptions.AssetFileis set then this performance gain will not be possible. However, now thatcompileTemplatesproperly locks the templates we can make theCompileTemplatesfunction public and thus allow downstream users in that case the option to leaveIsDevelopmentfalse and instead recompile their templates, when and if, they detect a change within their assets.Contains #92
