Reorganized web page attribute data handling. - Up to now the web browser used several fixed size arrays to hold the various types attribute data of the web page. This turned out to be way to inflexible for any non-trivial web page. Therefore now all attribute data is stored in a single buffer one after the other as they arrive from the parser only occupying the memory actually needed. This allows for pages with many links with rather short URLs as well as pages with few link with long URLs as well as pages with several simple forms as well as pages with one form with many form inputs. - Using the actual web page buffer to hold the text buffers of text entry fields was in general a cool idea but in reality it is often necessary to enter text longer than the size of the text entry field. Therefore the text buffer is now stored in the new unified attribute data buffer. - Splitting up the process of canonicalizing a link URL and actually navigating to the resulting URL allowed to get rid of the 'tmpurl' buffer used during form submit. Now the form action is canonicalized like a usual link, then the form input name/value pairs are written right into the 'url' buffer and afterwards the navigation is triggered. - Support for the 'render states' was completely removed. The only actually supported render state was centered output. The new unified attribute buffer would have complicated enumerating all widgets added to the page in order to adjust their position. Therefore I decided to drop the whole feature as the <center> tag is barely used anymore and newer center attributes are to hard to parse.

core/net/resolv: IPv6 and mDNS ("Bonjour") support. Major refactor. This patch updates the DNS resolver to support IPv6 and introduces an improved API for looking up DNS entries. This patch also adds optional support for mDNS lookups and responses to the DNS resolver. Here is a quick summary of the changes: * Added support for IPv6 lookups. * DNS queries now honor record expiration. * Added support for mDNS, compatible with "Bonjour". * Implemented a new lookup api, `resolv_lookup2()`, which provides more information about the state of the record(error, expired, looking-up, etc.). About mDNS/Bonjour Support -------------------------- This patch adds basic support for mDNS/Bonjour, which allows you to refer to the name of a device instead of its IP address. This is incredibly convenient for IPv6 addresses because they tend to be very long and difficult to remember. It is especially important for link-local IPv6 addresses, since not all programs support the '%' notation for indicating a network interface (required on systems with more than one network interface to disambiguate). In other words, instead of typing in this: * `http://[fe80::58dc:d7ed:a644:628f%en1]/` You can type this instead: * `http://contiki.local/` Huge improvement, no? The convenience extends beyond that: this mechanism can be used for nodes to talk to each other based on their human-readable names instead of their IPv6 addresses. So instead of a switch on `aaaa::58dc:d7ed:a644:628f` triggering an actuator on `aaaa::ed26:19c1:4bd2:f95b`, `light-switch.local` can trigger the actuator on `living-room-lights.local`. What you need to do to be able to look up `.local` names on your workstation depends on a few factors: * Your machine needs to be able to send and receive multicast packets to and from the LoWPAN. You can do this easily with the Jackdaw firmware on an RZUSBStick. If you have a border router, you will need it to bridge the mDNS multicast packets across the border. * If you are using a Mac, you win. All Apple devices support mDNS lookups. * If you are using Windows, you can install Apple's Bonjour for Windows package. (This may be already installed on your machine if you have installed iTunes) After you install this you can easily do `.local` lookups. * If you are using a Unix machine, you can install Avahi. The default hostname is set to `contiki.local.`. You can change the hostname programmatically by calling `resolv_set_hostname()`. You can change the default hostname by changing `CONTIKI_CONF_DEFAULT_HOSTNAME`. You may disable mDNS support by setting `RESOLV_CONF_SUPPORTS_MDNS` to `0`. --------------------------------- core/net/resolv: `resolv_lookup2()` -> `resolv_lookup()` Note that this patch should fix several `resolv_lookup()` bugs that already existed. There were many cases where `resolv_lookup()` was being called and the IP address ignored, but later code assumed that the IP address had been fetched... ANYWAY, those should be fixed now. --------------------------------- examples/udp-ipv6: Updated client to use MDNS to lookup the server. Also updated the Cooja regression test simulation.

Reorganized web page attribute data handling. - Up to now the web browser used several fixed size arrays to hold the various types attribute data of the web page. This turned out to be way to inflexible for any non-trivial web page. Therefore now all attribute data is stored in a single buffer one after the other as they arrive from the parser only occupying the memory actually needed. This allows for pages with many links with rather short URLs as well as pages with few link with long URLs as well as pages with several simple forms as well as pages with one form with many form inputs. - Using the actual web page buffer to hold the text buffers of text entry fields was in general a cool idea but in reality it is often necessary to enter text longer than the size of the text entry field. Therefore the text buffer is now stored in the new unified attribute data buffer. - Splitting up the process of canonicalizing a link URL and actually navigating to the resulting URL allowed to get rid of the 'tmpurl' buffer used during form submit. Now the form action is canonicalized like a usual link, then the form input name/value pairs are written right into the 'url' buffer and afterwards the navigation is triggered. - Support for the 'render states' was completely removed. The only actually supported render state was centered output. The new unified attribute buffer would have complicated enumerating all widgets added to the page in order to adjust their position. Therefore I decided to drop the whole feature as the <center> tag is barely used anymore and newer center attributes are to hard to parse.

core/net/resolv: IPv6 and mDNS ("Bonjour") support. Major refactor. This patch updates the DNS resolver to support IPv6 and introduces an improved API for looking up DNS entries. This patch also adds optional support for mDNS lookups and responses to the DNS resolver. Here is a quick summary of the changes: * Added support for IPv6 lookups. * DNS queries now honor record expiration. * Added support for mDNS, compatible with "Bonjour". * Implemented a new lookup api, `resolv_lookup2()`, which provides more information about the state of the record(error, expired, looking-up, etc.). About mDNS/Bonjour Support -------------------------- This patch adds basic support for mDNS/Bonjour, which allows you to refer to the name of a device instead of its IP address. This is incredibly convenient for IPv6 addresses because they tend to be very long and difficult to remember. It is especially important for link-local IPv6 addresses, since not all programs support the '%' notation for indicating a network interface (required on systems with more than one network interface to disambiguate). In other words, instead of typing in this: * `http://[fe80::58dc:d7ed:a644:628f%en1]/` You can type this instead: * `http://contiki.local/` Huge improvement, no? The convenience extends beyond that: this mechanism can be used for nodes to talk to each other based on their human-readable names instead of their IPv6 addresses. So instead of a switch on `aaaa::58dc:d7ed:a644:628f` triggering an actuator on `aaaa::ed26:19c1:4bd2:f95b`, `light-switch.local` can trigger the actuator on `living-room-lights.local`. What you need to do to be able to look up `.local` names on your workstation depends on a few factors: * Your machine needs to be able to send and receive multicast packets to and from the LoWPAN. You can do this easily with the Jackdaw firmware on an RZUSBStick. If you have a border router, you will need it to bridge the mDNS multicast packets across the border. * If you are using a Mac, you win. All Apple devices support mDNS lookups. * If you are using Windows, you can install Apple's Bonjour for Windows package. (This may be already installed on your machine if you have installed iTunes) After you install this you can easily do `.local` lookups. * If you are using a Unix machine, you can install Avahi. The default hostname is set to `contiki.local.`. You can change the hostname programmatically by calling `resolv_set_hostname()`. You can change the default hostname by changing `CONTIKI_CONF_DEFAULT_HOSTNAME`. You may disable mDNS support by setting `RESOLV_CONF_SUPPORTS_MDNS` to `0`. --------------------------------- core/net/resolv: `resolv_lookup2()` -> `resolv_lookup()` Note that this patch should fix several `resolv_lookup()` bugs that already existed. There were many cases where `resolv_lookup()` was being called and the IP address ignored, but later code assumed that the IP address had been fetched... ANYWAY, those should be fixed now. --------------------------------- examples/udp-ipv6: Updated client to use MDNS to lookup the server. Also updated the Cooja regression test simulation.

Reorganized web page attribute data handling. - Up to now the web browser used several fixed size arrays to hold the various types attribute data of the web page. This turned out to be way to inflexible for any non-trivial web page. Therefore now all attribute data is stored in a single buffer one after the other as they arrive from the parser only occupying the memory actually needed. This allows for pages with many links with rather short URLs as well as pages with few link with long URLs as well as pages with several simple forms as well as pages with one form with many form inputs. - Using the actual web page buffer to hold the text buffers of text entry fields was in general a cool idea but in reality it is often necessary to enter text longer than the size of the text entry field. Therefore the text buffer is now stored in the new unified attribute data buffer. - Splitting up the process of canonicalizing a link URL and actually navigating to the resulting URL allowed to get rid of the 'tmpurl' buffer used during form submit. Now the form action is canonicalized like a usual link, then the form input name/value pairs are written right into the 'url' buffer and afterwards the navigation is triggered. - Support for the 'render states' was completely removed. The only actually supported render state was centered output. The new unified attribute buffer would have complicated enumerating all widgets added to the page in order to adjust their position. Therefore I decided to drop the whole feature as the <center> tag is barely used anymore and newer center attributes are to hard to parse.

Reorganized web page attribute data handling. - Up to now the web browser used several fixed size arrays to hold the various types attribute data of the web page. This turned out to be way to inflexible for any non-trivial web page. Therefore now all attribute data is stored in a single buffer one after the other as they arrive from the parser only occupying the memory actually needed. This allows for pages with many links with rather short URLs as well as pages with few link with long URLs as well as pages with several simple forms as well as pages with one form with many form inputs. - Using the actual web page buffer to hold the text buffers of text entry fields was in general a cool idea but in reality it is often necessary to enter text longer than the size of the text entry field. Therefore the text buffer is now stored in the new unified attribute data buffer. - Splitting up the process of canonicalizing a link URL and actually navigating to the resulting URL allowed to get rid of the 'tmpurl' buffer used during form submit. Now the form action is canonicalized like a usual link, then the form input name/value pairs are written right into the 'url' buffer and afterwards the navigation is triggered. - Support for the 'render states' was completely removed. The only actually supported render state was centered output. The new unified attribute buffer would have complicated enumerating all widgets added to the page in order to adjust their position. Therefore I decided to drop the whole feature as the <center> tag is barely used anymore and newer center attributes are to hard to parse.

Therefore now all attribute data is stored in a single buffer one after the other as they arrive from the parser only occupying the memory actually needed. This allows for pages with many links with rather short URLs as well as pages with few link with long URLs as well as pages with several simple forms as well as pages with one form with many form inputs. - Using the actual web page buffer to hold the text buffers of text entry fields was in general a cool idea but in reality it is often necessary to enter text longer than the size of the text entry field. Therefore the text buffer is now stored in the new unified attribute data buffer. - Splitting up the process of canonicalizing a link URL and actually navigating to the resulting URL allowed to get rid of the 'tmpurl' buffer used during form submit. Now the form action is canonicalized like a usual link, then the form input name/value pairs are written right into the 'url' buffer and afterwards the navigation is triggered. - Support for the 'render states' was completely removed. The only actually supported render state was centered output. The new unified attribute buffer would have complicated enumerating all widgets added to the page in order to adjust their position. Therefore I decided to drop the whole feature as the <center> tag is barely used anymore and newer center attributes are to hard to parse.
