1 # Chrome Network Bug Triage : Labels
3 ## Some network label caveats
5 **Cr-UI-Browser-Downloads**
6 : Despite the name, this covers all issues related to downloading a file except
7 saving entire pages (which is **Cr-Blink-SavePage**), not just UI issues.
8 Most downloads bugs will have the word "download" or "save as" in the
9 description. Issues with the HTTP server for the Chrome binaries are not
12 **Cr-UI-Browser-SafeBrowsing**
13 : Bugs that have to do with the process by which a URL or file is determined to
14 be dangerous based on our databases, or the resulting interstitials.
15 Determination of danger based purely on content-type or file extension
16 belongs in **Cr-UI-Browser-Downloads**, not SafeBrowsing.
18 **Cr-Internals-Network-SSL**
19 : This includes issues that should be also tagged as **Cr-Security-UX**
20 (certificate error pages or other security interstitials, omnibox indicators
21 that a page is secure), and more general SSL issues. If you see requests
22 that die in the SSL negotiation phase, in particular, this is often the
25 **Cr-Internals-Network-DataProxy**
26 : Flywheel / the Data Reduction Proxy. Issues require "Reduce Data Usage" be
27 turned on. Proxy url is [https://proxy.googlezip.net:443](), with
28 [http://compress.googlezip.net:80]() as a fallback. Currently Android and
31 **Cr-Internals-Network-Cache**
32 : The cache is the layer that handles most range request logic (Though range
33 requests may also be issued by the PDF plugin, XHRs, or other components).
35 **Cr-Internals-Network-SPDY**
36 : Covers HTTP2 as well.
38 **Cr-Internals-Network-HTTP**
39 : Typically not used. Unclear what it covers, and there's no specific HTTP
42 **Cr-Internals-Network-Logging**
43 : Covers **about:net-internals**, **about:net-export** as well as the what's
46 **Cr-Internals-Network-Connectivity**
47 : Issues related to switching between networks, ERR_NETWORK_CHANGED, Chrome
48 thinking it's online when it's not / navigator.onLine inaccuracies, etc.
50 **Cr-Internals-Network-Filters**
51 : Covers SDCH and gzip issues. ERR_CONTENT_DECODING_FAILED indicates a problem
52 at this layer, and bugs here can also cause response body corruption.
54 ## Common non-network labels
56 Bugs in these areas often receive the **Cr-Internals-Network** label, though
57 they fall largely outside the purview of the network stack team:
60 : Issues submitting forms, forms having weird data, forms sending the wrong
64 : Cross origin issues are sometimes loader related. Blink also has an
65 in-memory cache, and when it's used, requests don't appear in
66 about:net-internals. Requests for the same URL are also often merged there
67 as well. This does *not* cover issues with content/browser/loader/ files.
69 **Cr-Blink-ServiceWorker**
71 **Cr-Blink-Storage-AppCache**
73 **Cr-Blink-WebSockets**
76 : Generic issues with sync/async XHR requests - missing request or response
77 headers, multiple headers, etc. These will often run into issues in certain
78 corner cases (Cross origin / CORS, proxy, whatever). Attach all labels that
82 : Sharing data/tabs/history/passwords/etc between machines not working.
84 **Cr-Services-Chromoting**
86 **Cr-Platform-Extensions**
87 : Issues extensions loading / not loading / hanging.
89 **Cr-Platform-Extensions-API**
90 : Issues with network related extension APIs should have this label.
91 chrome.webRequest is the big one, I believe, but there are others.
93 **Cr-Internals-Plugins-Pepper[-SDK]**
95 **Cr-UI-Browser-Omnibox**
96 : Basically any issue with the omnibox. URLs being treated as search queries
97 rather than navigations, dropdown results being weird, not handling certain
98 unicode characters, etc. If the issue is new TLDs not being recognized by
99 the omnibox, that's due to Chrome's TLD list being out of date, and not an
100 omnibox issue. Such TLD issues should be duped against
101 http://crbug.com/37436.
103 **Cr-Internals-Media-Network**
104 : Issues related to media. These often run into the 6 requests per hostname
105 issue, and also have fun interactions with the cache, particularly in the
108 **Cr-Internals-Plugins-PDF**
109 : Issues loading pdf files. These are often related to range requests, which
110 also have some logic at the Internals-Network-Cache layer.
112 **Cr-UI-Browser-Navigation**
114 **Cr-UI-Browser-History**
115 : Issues which only appear with forward/back navigation.
117 **Cr-OS-Systems-Network** / **Cr-OS-Systems-Mobile** / **Cr-OS-Systems-Bluetooth**
118 : These should be used for issues with ChromeOS's platform network code, and
119 not net/ issues on ChromeOS.
121 **Cr-Blink-SecurityFeature**
122 : CORS / Cross origin issues. Main frame cross-origin navigation issues are
123 often actually **Cr-UI-Browser-Navigation** issues.
126 : Privacy related bug (History, cookies discoverable by an entity that
127 shouldn't be able to do so, incognito state being saved in memory or on disk
128 beyond the lifetime of incognito tabs, etc). Generally used in conjunction
131 **Type-Bug-Security**
132 : Security related bug (Allows for code execution from remote site, allows
133 crossing security boundaries, unchecked array bounds,
