Added a new script to package the webextension. This will automatically
build and zip the source code and the webextension for upload. It take a
version as an argument and then checks the version in the manifest, and
locally commits a version bump.
last was initialised twice (creating a shadow), the second time inside
a case statement. The second initialisation is removed, keeping the use
of last aligned to the isame style as its use other parts of the case
statement.
- Error strings are no longer capitalized nor end with punctuation
- Alias import
- Remove extraneous initilisation code (No need to provide zero value
for variables, because the compiler does that anyway)
We need to set up the pion/webrtc logger to write output to the
snowflake log, otherwise the warnings we are getting from the pion
library are being lost.
Note: this requires go version 1.13 and later in order to use the
`log.Writer()` function.
This commit fixes a small error introduced in a previous commit. Servers
given by command line options weren't being added to the configuration
because we were checking for `iceServers` to be nil instead of not nil.
Modified the snowflake client to use pion/webrtc as the webrtc library.
This involved a few small changes to match function signatures as well
as several larger ones:
- OnNegotiationNeeded is no longer supported, so CreateOffer and
SetLocalDescription have been moved to a go routine called after the
other peer connection callbacks are set
- We need our own deserialize/serialize functions
- We need to use a SettingEngine in order to access the
OnICEGatheringStateChange callback
The API is very similar, differences were mostly due to:
- closing peer connections and datachannels (no destroy/delete methods)
- different way to set datachannel/peer connection callbacks
- differences in whether functions take pointers or values
- no serialize/deserialize functions in the API
The safelog Write function can be called from multiple go routines, and
it was not thread safe. These locks in particular allow us to pass the
logscrubber's output io.Writer to other libraries, such as pion.
Many of our log messages were being used to generate metrics, but are
now being aggregated and logged to a separate metrics log file and so we
don't need them in the regular logs anymore.
This addresses the goal of ticket #30830, to remove unecessary messages
and keep broker logs for debugging purposes.
Added a folder to hold snowflake specifications. This folder starts with
a file containing a partial broker spec that focuses on the metrics
reporting spec for CollecTor at the moment.
The broker /debug page was displaying proxy IDs and roundtrip times. As
serna pointed out in bug #31460, the proxy IDs can be used to launch a
denial of service attack. As the metrics team pointed out on #21315, the
round trip time average can be potentially sensitive.
This change displays only proxy counts and uses ID lengths to
distinguish between standalone proxy-go instances and browser-based
snowflake proxies.
