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