Fix cache issue & IP filtering helpers #1221

nurhat · 2020-05-05T14:42:28Z

Proposed Changes

Add content language header to CacheKeyGenerator
IP filtering tries to find exact client (proxy, firewall, loadbalance)
Schema can be modified by a service discovery provider
Cache only if HTTP status is OK

@nurhat Hi!
Thanks for the great PR and your interest in Ocelot!

What issue is this PR related to?

Could you work on merge conflicts please?
It seems your fork too old. Go to your fork and merge open PRs to sync your fork please!

raman-m · 2023-07-28T17:46:20Z

@nurhat
I've rebased feature branch onto ThreeMammals:develop.
Because you use develop branch as feature one, therefore in future you will not be able to create a new feature branch from develop one because it has a diff, 7 commits ahead of ThreeMammals:develop.

Wish you good luck during code review!

And once again,
Maybe, this PR is related to an issue in backlog... Which one?

+        return string.Empty;
+    }
+
+    public static List<string> SplitCsv(this string csvList, bool nullOrWhitespaceInputReturnsNull = false)


could be private

...till the moment the author will write at least one unit test for this method. 🤣

unless no one uses it outside of this class

+        return string.Empty;
+    }
+
+    public static List<string> SplitCsv(this string csvList, bool nullOrWhitespaceInputReturnsNull = false)


Suggested change

public static List<string> SplitCsv(this string csvList, bool nullOrWhitespaceInputReturnsNull = false)

private static IReadOnlyCollection<string> SplitCsv(this string csvList, bool nullOrWhitespaceInputReturnsNull = false)

Ensuring about strong safety by IReadOnlyCollection and making the method private don't give much outcome by having it as read-only.

this method is only use in this class, so, it must be private. There will always be time to make it public, if necessary

+        if (string.IsNullOrWhiteSpace(csvList))
+        {
+            return nullOrWhitespaceInputReturnsNull ? null : new List<string>();


Suggested change

return nullOrWhitespaceInputReturnsNull ? null : new List<string>();

return nullOrWhitespaceInputReturnsNull ? null : Array.Empty<string>();

+            .AsEnumerable()
+            .Select(s => s.Trim())
+            .ToList();


Suggested change

.ToList();

.ToArray();

@RaynaldM
Why to array?
The author just wants to match the returning type which is List<string>😄
Are you kidding? 😉 He will get compilation error. 🤣

if @nurhat applies all these changes no problems compiling.

I always recommend the use of Single-Dimensional Array because it is the most sober in memory and cpu.
If we don't need more functions, like in lists and other dictionaries, then let's use the simpler and more sober one

@RaynaldM Ray,
Thanks for your code review! 🤝

+            {
+                Logger.LogDebug($"http request failed,  could not create cache for {downstreamUrlKey}");


There's a double space. Also message could be better, something like "http request failed, skipped caching for {downstreamUrlKey}"
