-------------------------------------------------------------------------------- /docs/api/submissions/create_a_submission.md: -------------------------------------------------------------------------------- 1 | ### Create a Submission [POST] 2 | Creates new submission. Created submission waits in queue to be processed. On successful 3 | creation, you are returned submission token which can be used to check submission status. 4 | 5 | If submission's `source_code`, `stdin` or `expected_output` contains non printable characters, or 6 | characters which cannot be sent with JSON, then set `base64_encoded` parameter to `true` and 7 | send these attributes Base64 encoded. Your responsibility is to encode each of mentioned attributes 8 | (`source_code`, `stdin` and `expected_output`) even if just one of them contains non printable 9 | characters. By default, this parameter is set to `false` and Judge0 API assumes you are sending plain text data. 10 | 11 | By default you are returned submission token on successful submission creation. With this token 12 | you can [check submission status](#submission-submission-get). 13 | Instead of checking submission status by making another request, send `wait` query parameter and set it to `true` 14 | which will enable you to get submission status immediately as part of response to the request you made. 15 | Please note that this feature may or may not be 16 | enabled on all Judge0 API hosts. So before using this feature please check [configuration](#system-and-configuration-configuration-info-get) 17 | of Judge0 API you are using. On an [official Judge0 API](https://api.judge0.com) this feature **is enabled**. 18 | 19 | + Parameters 20 | + base64_encoded = `false` (optional, boolean, `false`) ...

It also gives users 8 | insight on some *default configuration values* which are used when their programs are run. 9 | 10 | Each of these *configuration variables* have *default values* which we consider as recommended in case you are not sure should you change them. 11 | 12 | We will refer to *default values* as values which Judge0 API automatically assigns to each of these *configuration variables*, 13 | if admin didn't set them. For example, default value of *configuration variable* `cpu_time_limit` is `2`. 14 | 15 | |# |Name|Type |Unit |Description|Default Value| 16 | |:---:|:---|:---:|:---:|:----------|:------------| 17 | |1|`enable_wait_result`|boolean||If enabled user can request to synchronously wait for submission result on submission create.|true| 18 | |2|`enable_compiler_options`|boolean||If enabled user can set `compiler_options`.|true| 19 | |3|`allowed_languages_for_compile_options`|list of strings||Languages for which setting compiler options is allowed.|Empty, i.e. for all languages it is allowed to set compiler options.| 20 | |4|`enable_command_line_arguments`|boolean||If enabled user can set `command_line_arguments`.|true| 21 | |5|`enable_submission_delete`|boolean||If enabled authorized user can [delete a submission](#submissions-submission-delete).|false| 22 | |6|`max_queue_size`|integer||Maximum number of submissions that can wait in queue.|100| 23 | |7|`cpu_time_limit`|float|second|Default runtime limit for every program (in seconds). Decimal numbers are allowed. Time in which the OS assigns the processor to different tasks is not counted.|2| 24 | |8|`cpu_extra_time`|float|second|When a time limit is exceeded, wait for extra time, before killing the program. This has the advantage that the real execution time is reported, even though it slightly exceeds the limit.|0.5| 25 | |9|`wall_time_limit`|float|second|Limit wall-clock time in seconds. Decimal numbers are allowed. This clock measures the time from the start of the program to its exit, for an external event. We recommend to use `cpu_time_limit` as the main limit, but set `wall_time_limit` to a much higher value as a precaution against sleeping programs.|5| 26 | |10|`memory_limit`|integer|kilobyte|Limit address space of the program in kilobytes.|128000| 27 | |11|`stack_limit`|integer|kilobyte|Limit process stack in kilobytes.|64000| 28 | |12|`max_processes_and_or_threads`|integer||Maximum number of processes and/or threads program can create.|60| 29 | |13|`enable_per_process_and_thread_time_limit`|boolean||If `true` then `cpu_time_limit` will be used as per process and thread.|false| 30 | |14|`enable_per_process_and_thread_memory_limit`|boolean||If `true` then `memory_limit` will be used as per process and thread.|true| 31 | |15|`max_file_size`|integer|kilobyte|Limit size of files created (or modified) by the program.|1024| 32 | |16|`number_of_runs`|integer||Run each program this many times and take average of time and memory.|1| 33 | 34 | *Default configuration value* for each variable is given to you as response of this API call. For example, *default configuration value* 35 | for variable `cpu_extra_time` might be `2`, and if admin didn't set this, then it is `0.5` (*default value*). 36 | This means that admin set `cpu_extra_time` *configuration variable* to value `2` and we say it is now *default configuration value* for this 37 | variable `cpu_extra_time`. 38 | 39 | Every [submission](#submissions-submission) can change each of the configuration variables according to its needs. For example, 40 | user might create submission which has `cpu_time_limit` of `5` seconds. For security reasons we need to limit values of each of these 41 | configuration variables. For example, we don't want user to create a submission which has `cpu_time_limit` of `100000` seconds. 42 | 43 | For this security reason we are introducing *limit configuration variables* for each *configuration variable*. 44 | 45 | |# |Name|Type |Unit |Description|Default Value| 46 | |:---:|:---|:---:|:---:|:----------|:------------| 47 | |1|`max_cpu_time_limit`|float|second|Maximum custom

Judge0 API Dummy Client

11 |

12 | Judge0 API dummy client can be used to try and test features of Judge0 API. Data is not validated on client side. 13 | Client first creates new submission and then fetches submission status every 1500ms. 14 | Client stops fetching submission status after recieving an error or when submission status is not In Queue or Processing. 15 |

16 |

17 | Note that you need to define API URL. This is the base url of some Judge0 API host (e.g. https://api.judge0.com). 18 | Description of network errors can be found in console of your browser, so check that for more information. 19 |
