2021-09-02Add element to specify expression that defines length of a structPovilas Kanapickas1-2/+19
Currently the layout of a struct is used to compute its size. This works fine in case of structs of fixed size. However this introduces forwards-compatibility problems in cases when the struct has multiple variants and the exact variant is specified by the value of some field (e.g. in the case of <switch> elements). Future revisions of protocols may introduce new layout variants, in which case the old code does not know the size of the struct variant and can't parse the incoming byte stream. Instead of relying on knowledge about the layout of data structures we should instead use the length field for length information. This way when old client libxcb communicates with newer server it can at least ignore unknown struct variants.
2017-03-11add support for eventstructChristian Linhart1-0/+29
eventstruct is a new xml element that allows to use events as part of requests. This is, e.g., needed by the SendExtensionEvent request of the XINPUT extension. Signed-off-by: Christian Linhart <chris@demorecorder.com>
2016-01-27optionally enforce serialization of padsChristian Linhart1-1/+8
From now on, due to a patch in libxcb, pads will not be serialized anymore. This is to maintain ABI-compatibility when adding explicit align pads. However, some align pads were already be serialized in prior official versions of libxcb. Therefore we need a method to enforce serialization, so we can maintainn ABI compatibility with that legacy.

V2: patch revised according to suggestion from Peter Harris: * add the restriction that <enumref> inside <bitcase> can only refer to an enum's <bit> members, and <enumref> inside <case> can only refer to an enum's <value> members.

2014-08-25Add "altmask" attribute, like "altenum" for masksRan Benita1-2/+3
"altmask" means the field is principally a bitmask of bits from the enum, but in some cases can obtain other values (e.g. "out-of-band" data in a free bit). Several fields in xinput will benefit from this extra metadata.
