It is recommended you create a directory structure of cse109.fall2021/prog2 under your home directory, and do your development work for this assignment in the prog2 directory. Except for syscall errors and the conditions specified below, the return code is 0.Ģ01 - Incorrect/unexpected argument enteredkj Your Stevens-style wrapped system calls should exit with the errno value and the strerror(errno) message (still to stderr). When we compile for grading, we will not compile with -DDEBUG, and it is fine if your submitted code has statements like “#ifdef DEBUG …” or “if (DEBUG) ”.Įxit with the following return code and an appropriate message to stderr under the following conditions. This is fine, so long as it is obvious this is NOT your primary method for debug… which should be gdb. You may choose to pass -DDEBUG as a parameter to gcc to print additional information during debug. You need to create a makefile to manage the selective compilation of your relocatable and executable objects files. Your Stevens-style wrapped functions are to be placed in syscalls. You will need to create and manage the following files: hashTab_funcs.c, syscalls.h, and syscalls.c. You are given hashTab.c, global_defs.h, and hashTab_funcs.h. ![]() The table auto-resizes to maintain "optimum" performance. U key value # if key not in the table, value will be stored and a warning printedĭ key # if key not in the table, a warning will be printed ![]() R key # if key not in the table, a warning will be printed, otherwise value format is: action key action is one of the following characters: c r u dĬ key value # if key already in table, value will be updated and a warning printed Commands to perform the aboveĪctions may be specified in the input text file as follows. Keys can be any integer in the range and values can beĪny integer in the range. HashTab creates, retrieves, updates, and deletes key-value pairs in a hash table. Write a program whose executable name will be hashTab and which conforms to the following “specification” (which is actually the help message). Structures and accessing structure membersĭescription of Program and Program Requirements Prog2 - hashTab - Description CSE109 Fall 2021 Hashtab-jackwkeane created by GitHub Classroom Note:Īll programs were written and optimized for X86-64 machines with gcc module 7.10. This subset consisted of 1,104,514 tweets, whose ids are listed in the file continuous_rehydrated_no_retweets_ fall of 2021 as a part of Lehigh University's CSE 109: System Software. The ids of tweets in this dataset are listed in the file continuous_rehydrated_ids.txt.įinally, out of these rehydrated tweets, a subset was derived that filtered out all tweets that were pure retweets. Of the original 4,197,059 tweets gathered for this time period (listed in continuous_ids.txt), 3,941,653 could be rehydrated (i.e., they had not been deleted in the interim). In addition, the Twarc script had been run without the -extended argument, so the tweet data contained only truncated contents for many tweets.ĭue to this, a decision was taken to rehydrate a new dataset of tweets falling between T09:24Z and T14:42Z. For an unidentified reason, gathering did not occur between T06:17Z and T09:24Z. However, upon further inspection, problems were identified in the archiving. All 5,547,585 tweet IDs returned by this run are listed in the file original_. ![]() The dataset was gathered as follows: Between T09:19Z and T14:42Z, a Twarc version 1.6.1 script was called hourly to retrieve and archive tweets from Twitter matching the #brexit hashtag using the Twitter search API. However, Twitter allows the publication of tweet ids, from which the dataset can be reconstituted, with the exception of deleted tweets. This dataset contains lists of tweet ids for the tweets used as material by the "Brexit in Transnational Social Media" group in the Helsinki Digital Humanities Hackathon 2019.ĭue to restrictions in Twitter's terms of service, the full tweet dataset cannot be made public.
