Subject: dom_storage_limits.patch
|
|
|
|
This patch increases the DOM storage (e.g. `localStorage`
|
|
and `sessionStorage`) size quota from 10MiB to 100MiB.
|
|
Previous versions of this patch attempted to circumvent
|
|
the restriction altogether.
|
|
However, this can lead to other problems, such as crashing
|
|
the Dev Tools when attempting to read or write values that exceed
|
|
`IPC::Channel::kMaximumMessageSize` (128MiB).
|
|
|
|
Increasing the quota rather than bypassing it reduces the
|
|
amount of chromium code that needs to be changed for Electron
|
|
as well as keeps these storage areas limited to a bounded
|
|
size meanwhile giving application developers more space to work with.
