Such archives as well as +additional, repository-specific information can optionally be uploaded by the +automated build bots via the HTTP \c{POST} method using the +\c{multipart/form-data} content type (see the \l{bbot \c{bbot} documentation} +for details). The implementation in \c{brep} only handles uploading as well as +basic actions and verification (build session resolution, agent +authentication, checksum verification) expecting the rest of the upload logic +to be handled by a separate entity according to the repository policy. Such an +entity can be notified by \c{brep} about a new upload as an invocation of the +\i{handler program} (as part of the HTTP request) and/or via email. It could +also be a separate process that monitors the upload data directory. + +For each upload request \c{brep} performs the following steps. + +\ol| + +\li|Determine upload type. + +The upload type must be passed via the \c{upload} parameter in the query +component of the request URL.| + +\li|Verify upload size limit. + +The upload form-data payload size must not exceed \c{upload-max-size} specific +for this upload type.| + +\li|Verify the required \c{session}, \c{instance}, \c{archive}, and +\c{sha256sum} parameters are present. If \c{brep} is configured to perform +agent authentication, then verify that the \c{challenge} parameter is also +present. See the \l{bbot#arch-result-req Result Request Manifest} for +semantics of the \c{session} and \c{challenge} parameters. + +The \c{archive} parameter must be the build artifacts archive upload while +\c{sha256sum} must be its 64 characters SHA256 checksum calculated in the +binary mode.| + +\li|Verify other parameters are valid manifest name/value pairs. + +The value can only contain UTF-8 encoded Unicode graphic characters as well as +tab (\c{\\t}), carriage return (\c{\\r}), and line feed (\c{\\n}).| + +\li|Resolve the session. + +Resolve the \c{session} parameter value to the actual package build +information.| + +\li| Authenticate the build bot agent. + +Use the \c{challenge} parameter value and the resolved package build +information to authenticate the agent, if configured to do so.| + +\li|Generate upload request id and create request directory. + +For each upload request a unique id (UUID) is generated and a request +subdirectory is created in the \c{upload-data} directory with this id as its +name.| + +\li|Save the upload archive into the request directory and verify its +checksum. + +The archive is saved using the submitted name, and its checksum is calculated +and compared to the submitted checksum.| + +\li|Save the upload request manifest into the request directory. + +The upload request manifest is saved as \c{request.manifest} into the request +subdirectory next to the archive.| + +\li|Invoke the upload handler program. + +If \c{upload-handler} is configured, invoke the handler program passing to it +additional arguments specified with \c{upload-handler-argument} (if any) +followed by the absolute path to the upload request directory. + +The handler program is expected to write the upload result manifest to +\c{stdout} and terminate with the zero exit status. A non-zero exit status is +treated as an internal error. The handler program's \c{stderr} is logged. + +Note that the handler program should report temporary server errors (service +overload, network connectivity loss, etc.) via the upload result manifest +status values in the [500-599] range (HTTP server error) rather than via a +non-zero exit status. + +The handler program assumes ownership of the upload request directory and can +move/remove it. If after the handler program terminates the request directory +still exists, then it is handled by \c{brep} depending on the handler process +exit status and the upload result manifest status value. If the process has +terminated abnormally or with a non-zero exit status or the result manifest +status is in the [500-599] range (HTTP server error), then the directory is +saved for troubleshooting by appending the \c{.fail} extension to its name. +Otherwise, if the status is in the [400-499] range (HTTP client error), then +the directory is removed. If the directory is left in place by the handler or +is saved for troubleshooting, then the upload result manifest is saved as +\c{result.manifest} into this directory, next to the request manifest. + +If \c{upload-handler-timeout} is configured and the handler program does not +exit in the allotted time, then it is killed and its termination is treated as +abnormal. + +If the handler program is not specified, then the following upload result +manifest is implied: + +\ +status: 200 +message: <upload-type> upload is queued +reference: <request-id> +\ + +| + +\li|Send the upload email. + +If \c{upload-email} is configured, send an email to this address containing +the upload request manifest and the upload result manifest.| + +\li|Respond to the client. + +Respond to the client with the upload result manifest and its \c{status} value +as the HTTP status code.| + +| + +Check violations (max size, etc) that are explicitly mentioned above are +always reported with the upload result manifest.
