Make url by value in Request There's some tough-to-track-down safety problems in http Request. This commit is an attempt to make things more safe, even if it isn't clear how the old code was wrong. Previously, the old code took a url_view from the target() string for a given URI. This was effectively a pointer, and needed to be updated in custom move/copy constructors that were error prone to write. This commit moves to taking the URI by non-view, which involves a copy, but allows us to use the default move and copy constructors, as well as have no internal references within Request, which should improve the safety and reviewability. There's already so many string copies in bmcweb, that this is unlikely to show up as any sort of performance regression, and simple code is much better in this case. Note, because of a bug in boost::url, we have to explicitly construct a url_view in any case where we want to use segments() or query() on a const Request. This has been reported to the boost maintainers, and is being worked for a long term solution. https://github.com/boostorg/url/pull/704 Tested: Redfish service validator passed on last commit in series.

This component attempts to be a "do everything" embedded webserver for OpenBMC.
The webserver implements a few distinct interfaces:
bmcweb at a protocol level supports http and https. TLS is supported through OpenSSL.
Bmcweb supports multiple authentication protocols:
Each of these types of authentication is able to be enabled or disabled both via runtime policy changes (through the relevant Redfish APIs) or via configure time options. All authentication mechanisms supporting username/password are routed to libpam, to allow for customization in authentication implementations.
All authorization in bmcweb is determined at routing time, and per route, and conform to the Redfish PrivilegeRegistry.
*Note: Non-Redfish functions are mapped to the closest equivalent Redfish privilege level.
bmcweb is configured per the meson build files. Available options are documented in meson_options.txt
meson builddir ninja -C builddir
If any of the dependencies are not found on the host system during configuration, meson will automatically download them via its wrap dependencies mentioned in bmcweb/subprojects.
bmcweb relies on some on-system data for storage of persistent data that is internal to the process. Details on the exact data stored and when it is read/written can seen from the persistent_data namespace.
When SSL support is enabled and a usable certificate is not found, bmcweb will generate a self-signed a certificate before launching the server. Please see the bmcweb source code for details on the parameters this certificate is built with.
bmcweb is capable of aggregating resources from satellite BMCs. Refer to AGGREGATION.md for more information on how to enable and use this feature.
