Abstract GitHub projects can be easily replicated through the site’s fork process or through a Git clone-push sequence. This is a problem for empirical software engineering, because it can lead to skewed results or mistrained machine learning models. We provide a dataset of 10.6 million GitHub projects that are copies of others, and link each record with the project’s ultimate parent. The ultimate parents were derived from a ranking along six metrics. The related projects were calculated as the connected components of an 18.2 million node and 12 million edge denoised graph created by directing edges to ultimate parents. The graph was created by filtering out more than 30 hand-picked and 2.3 million pattern-matched clumping projects. Projects that introduced unwanted clumping were identified by repeatedly visualizing shortest path distances between unrelated important projects. Our dataset identified 30 thousand duplicate projects in an existing popular reference dataset of 1.8 million projects. An evaluation of our dataset against another created independently with different methods found a significant overlap, but also differences attributed to the operational arXiv:2002.02314v3 [cs.SE] 15 Jun 2020 definition of what projects are considered as related.

1 Introduction

Anyone can create a copy of a GitHub project through a single effortless click on the project’s fork button. Similarly, one can also create a repository copy with just two Git commands. Consequently, GitHub contains many millions of copied projects. This is a problem for empirical software engineering. First, when data containing multiple copies of a repository are analyzed, the results can end up skewed [27]. Second, when such data are used to train machine learning models, the corresponding models can behave incorrectly [23, 2]. In theory, it should be easy to filter away copied projects. The project details provided by the GitHub API contain the field fork, which is true for forked projects. They also include fields under parent or source, which contain data concerning the fork source. In practice, the challenges of detecting and grouping together copied GitHub repositories are formidable. At the computational level, they involve finding among hundreds of millions of projects those that are near in a space of billions of dimensions (potentially shared commits). The use of GitHub for courses and coursework with hundreds of thousands of participants,1 for experimenting with version control systems,2 and for all kinds of frivolous or mischievous activity3 further complicates matters. In the following sections we present how we created a dataset identifying and grouping together GitHub projects with shared ancestry or commits (Sections 2 and 3), the data schema and availability (Section 4), an evaluation of data quality (Section 6), indicative findings based on the dataset (Section 5), related work (Section 7), and ideas for research and improve- ments (Section 8).

Figure 1: Overview of the dataset creation process 2 Dataset Creation

An overview of the dataset’s construction process is depicted in Figure 1. The projects were selected from GitHub by analyzing the GHTorrent [13, 11] dataset (release 2019-06-01) by means of the simple-rolap relational online analytical processing and rdbunit relational unit testing frameworks [14]. Following published recommendations [22], the code and primary data associated with this endeavor are openly available online,4 and can be used to replicate the dataset or construct an updated version from newer data. The GHTorrent dataset release we used contains details about 125 million (125 486 232) projects, one billion (1 368 235 072) individual commits, and six billion (6 251 898 944) commits associated with (possibly multiple, due to forks and merges) projects. We ﬁrst grouped shared commits to a single “attractor” project, which was derived based on the geometric mean (Table all project mean metric— 125 486 232 records—Listing 2) of six quality attributes:5 recency of the latest commit (Table most recent commit—100 366 312 records—Listing 3), as well as the number of stars (Table project stars—10 317 662 records— Listing 4), forks (Table project forks—6 958 551 records—Listing 5), commits (Table project ncommits—100 366 312 records—Listing 6), issues (Ta- ble project issues—9 498 704 records—Listing 7), and pull requests (Table project pull requests—7 143 570 records—Listing 8). In addition, the project- id was used as a tie-breaker. To avoid the information loss caused by zero values [20], we employed the following formula proposed by del Cruz and Kref [9]: n ! 1 X G (X) = exp log (x + δ ) − δ ,X n i ∗ ∗ i=1 with δ∗ calculated to have the value of 0.001 for our data. We used a query utilizing the SQL window functions in order to group together shared commits (Table projects sharing commits—44 380 204 records—Listing 9) without creating excessively large result sets (see Listing 16 in the appendix). To cover holes in the coverage of shared commits, we complemented the projects sharing commits table with projects related by GitHub project forks, after removing a set of hand-picked and heuristic-derived projects that mistakenly linked together unrelated clusters (Table blacklisted projects— 2 341 896 records—Listing 10). In addition, we removed from the combined

4 graph non-isolated nodes having between two and five edges, in order to reduce unwanted merges between unrelated shared commit and fork clusters. The method for creating the blacklisting table, along with the details behind the denoising process, are explained in Section 3. We subsequently converted projects with shared commits or shared fork ancestry into an (unweighted) graph to find its connected components, which would be the groups of related projects. We identified connected components using the GraphViz [10] ccomps tool (Table acgroups—18 203 053 records—Listing 11). The final steps involved determining the size of each group (Table group size—2 472 758 records—Listing 12), associating it with each project (Table project group size—18 203 053 records—Listing 13) and its metrics (Table project metrics—18 203 053 records—Listing 14), obtaining the mean metric for the selected projects (Table project mean metric— 18 203 053 records—Listing 15), and associating with each group the project excelling in the metric (Table highest mean in group—7 553 705 records— Listing 16). This was then used to create the deduplication table (Table deduplicate by mean—10 649 348 records—Listing 17) by partnering each project with a sibling having the highest mean value in the calculated metrics.

3 Down the Rabbit Hole

We arrived at the described process after numerous false starts, experiments, and considerable manual effort. Some problems included the discovery that in GHTorrent shared commits do not always lead to the same ancestral commit, a query that exhausted 128GB of RAM, and a result set that exceeded the maximum number of rows supported by PostgreSQL (four billion). Here we provide details regarding the technical difficulties associated with the dataset’s creation, the rationale for the design of the adopted processing pipeline, and the process of the required hand-cleaning and denoising. Our initial plan for reducing the problem’s high dimensionality involved associating each commit with a parent-less ancestor. In theory, each graph component of copied projects would have a unique such ancestor, allowing us to easily group projects together. In practice, we found that the commit history is incomplete, and that various projects share multiple ancestries. Our next approach for finding shared commits was based on grouping the records of the project and commit identifier table by the commit identifier, to identify projects with common commits. This process ran out of memory on a 128 GB RAM machine. We tried to run a query to export

5 the data into a file, but this also failed with an error “PGresult cannot support more than INT MAX tuples”. In the end, we resorted to dumping the commit and project identifier table with the database’s dump utility, pg dump, and filtering the output to obtain the required data. We sorted the file by the commit identifier as the primary key (Unix sort can handle arbitrary amounts of data by sorting in batches and then merge-sorting the intermediate files), and then used a small awk script to create in memory (9 GB RAM) a set of projects sharing commits, thus reducing the amount of downstream data. Our manual verification of large graph components uncovered a mega- component of projects with 4 278 791 members. Among the component’s projects were many seemingly unrelated popular ones, such as the following ten: FreeCodeCamp/FreeCodeCamp, facebook/react, getify/You-Dont- Know-JS, robbyrussell/oh-my-zsh, twbs/bootstrap, Microsoft/vscode, github/gitignore, torvalds/linux, nodejs/node, and flutter/flutter. We experimented with introducing weights to the graph, changing the edge-creation algorithm to include only projects sharing at least two commits. According to a percentile calculation of commits in GHTorrent, this could have drastic consequences, because only the top 60% of projects or- dered by the number of recorded commits have more than two commits. The size of the mega-component was reduced, but it still contained 3 202 377 members. (The number of components also fell from 6 103 690 to 6 065 658.) Given that weights did not break up the mega-component, we eventually kept the graph unweighted. We wrote a graph-processing script to remove from the graph all but one edges from projects with up to five edges. We chose five based on the average number of edges per node with more than one edge (3.8) increased by one for safety. We also looked at the effect of other values. Increasing the denoising limit up to ten edges reduced the size of the mega-component only little to 2 523 841. Consequently, we kept it at five to avoid removing too many duplicate projects. This improved somewhat the situation, reducing the size of the mega-component to 2 881 473 members. Studying the mega-component we observed that many attractor projects were personal web sites.6,7 Focusing on them we found that apparently many clone a particular personal style builder, build on it, force push the commits, and then repeat the process with another builder project. For example,

6Figure 2 and G1. 7The referenced graph images GN are distributed with the paper’s replication package. All but one are also included in this note’s appendix as zoomable ﬁgures. The yellow- colored nodes are the ones belonging in the set of top-ranked projects.

6 it seems that through this process, wicky-info/wicky-info.github.io shares commits with 139 other projects. Based on this insight we excluded projects with names indicating web sites (all ending in github.io), and also removed from the graph nodes having between two and five edges, considering them as adding noise. This reduced considerably the mega-component size in the graph of projects with shared commits, to the point where the largest component consisted mostly of programming assignments forked and copied thousands of times (jtleek/- datasharing — 199k forks, rdpeng/ProgrammingAssignment2 — 119k, rdpeng/RepData PeerAssessment1 — 32.3k). We also joined the generation of the fork tree and the common commit graph to reduce their interference, applying the denoising algorithm to both. This reduced the clusters to very reasonable sizes, breaking the mega- component to only include a few unrelated projects,8 which was further improved by blacklisting a couple of Android Open Source Project repositories.9 We manually inspected the five projects with the highest mean ranking in each of the first 250 clusters, which comprise about 1.6 million projects. The most populous component (Linux) had 175 184 members and the last, least populous, component (vim) had 1912 members. Many cases of several high-ranked projects in the same component involved genuine forks. This is for example the case of MariaDB/server linking percona/percona-server, mysql/mysql-server, and facebook/mysql-8.0, among others.10 Where these referred to different projects, we drew a map of shortest path between the 49 top-ranked projects and the first or 50th one, and blacklisted low-ranked projects that were linking together unrelated repositories. Resolved examples include the linking of Docker with Go,11 Django with Ruby on Rails,12 Google projects with zlib,13 Diaspora with Arduino,14 Elastic Search with Pandas,15 Definitely Types with RxJS,16 Ansible with

We also looked at the number of edges of each node in the component, reasoning that a single project was somehow acting as a hub, gluing all

8 disparate projects together. We indeed found a project (jlord/patchwork) with a very large number of edges (11 735), but these were consistent with the number of its forks (31 449), and also connections between unrelated projects were not passing through it. To further investigate what brings the component’s projects together, we selected from the component one popular project with relatively few forks (creationix/nvm), and applied Dijkstra’s shortest path algorithm to find how other projects got connected to it. We drew paths from that project to 30 other popular projects belonging to the same component, and started verify- ing each one by hand. We looked at the shared commits between unrelated projects that we found connected, such as yui-knk/rails and seuros/django. Some (very few) commits appear to be shared by an inordinate number of projects. At the top, three commits are shared by 100 683 projects, another three by 67 280, and then four by 53 312. However, these numbers are not necessarily wrong, because there are five projects with a cor- respondingly large number of forks: 125 491 (jtleek/datasharing), 124 326 (rdpeng/ProgrammingAssignment2), 111 986 (octocat/Spoon-Knife), 70 137 (tensorflow/tensorflow), and 66 066 (twbs/bootstrap). The first two commits are associated with many (now defunct) projects of the user dvcsconnectortest (missingcommitsfixproof, missingcommitstest, and then missingcommitstest 250 1393252414399) for many different trailing numbers. How- ever, the particular user is associated with very few commits, namely 1240, so it is unlikely that these commits have poisoned other components through transitive closure. We later on improved the denoising to incorporate components that could be trivially determined for isolation, by looking at just the neigh- boring nodes. The algorithm we employed is applied to all nodes n having between two and five edges; the ones we used to consider as noise. It sums up as s being the number of edges of all nodes n0 that were directly connected to n. If s is equal to the edges leading to n, then n and its immediate neighbors form a component, otherwise it is considered as adding noise and is disconnected from its neighbors. For a graph with edges E the condition for a node n being considered as noise, can be formally described as

0 0 X 0 00 0 00 (n, n )|(n, n ) ∈ E 6= {(n , n )|(n , n ) ∈ E} ∀n0|(n,n0)∈E

Applying this algorithm (Listing 1) decreased the number of ignored “noise projects” marginally from 37 660 040 to 37 333 119, increasing, as expected, the number of components by the same amount, from 2 145 837 to 2 472 758,

4 Dataset Overview

The dataset is provided41 as two files identifying GitHub repositories using the login-name/project-name convention. The file deduplicate names contains 10 649 348 tab-separated records mapping a duplicated source project to a definitive target project. The file forks clones noise names is a 50 324 363 member superset of the source projects, containing also projects that were excluded from the mapping as noise. The files are to be used as follows. After selecting some projects for conducting an empirical software engineering study with GitHub projects, the first file should be used to map potentially duplicate projects into a set of definitive ones. Then, any remaining projects that appear in the second file should be removed as these are likely to be low-value projects with a high probability of undesirable duplication.

5 Duplication in Existing Datasets

As an example of use of our dataset, we deduplicated the Reaper dataset [31], which contains scores concerning seven software engineering practices for about 1.8 million (1 853 205) GitHub projects. The study has influenced various subsequent works [35, 6, 1, 8] through the provided recommendations and filtering criteria for curating collected repositories. The authors have excluded deleted and forked projects, considering the latter as near duplicates. Around 30 thousand (30 095) duplicate projects were identified in the Reaper dataset using deduplicate names. The first ten components with the most recurrences involve the following ultimate parents and repetitions: torvalds/linux (2614), gatsbyjs/gatsby (545), boxen/our-boxen (229), backdrop/backdrop (121), publify/publify (110), boostorg/boost (109), llvm- mirror/llvm (108), laravel/framework (98), universal-ctags/ctags (89), saas- book/hw3 rottenpotatoes (87). In addition, the deduplication of the 800 hand-picked projects used in the classifiers’ training and validation processes unveiled only nine duplicate instances in the organization dataset, one in the utility, and none in the validation. These include aspnet/Mvc

(7), apache/flink (2), mozilla/bedrock (2), and bitcoin/bitcoin (2) in the organization, and torvalds/linux (2) in the utility. Further investigation is required to measure any potential impact of the ten duplicate projects on the classification outcome. Nevertheless, researchers selecting projects from Reaper for their work can benefit from our dataset to filter out duplicate occurrences, to further improve the quality of selected projects and avoid the problems outlined in Section 1.

6 Evaluation

We evaluated this dataset, which was constructed by identifying connected components based on forks and shared commits (CCFSC), through a quan- titative and qualitative comparison with a similar dataset constructed using community detection of shared commits (CDSC) [30]. An overview of the basic characteristics of the two datasets appears in Table 1. The two datasets share a substantial overlap both in terms of source projects (8 157 317) and in terms of cluster leaders (5 513 580). On the other hand, it is clear that CDSC is considerably more comprehensive than CCFSC in order of magni- tude, covering more repositories. An important factor in its favor is that it covers other forges apart from GitHub, and therefore its population is a superset of CCFSC’s. However, if one also considers the projects that CCFSC considers as noise (personal projects or projects with conﬂicting aﬃliations), the overlap swells to 40 338 421, covering about a third of the total. Fur- thermore, the fact that the increase in the Reaper dataset duplication in the CDSC dataset is only about double that of the CCFSC dataset indicates that the increased coverage of CCFSC may not be relevant for some empirical software engineering studies. These factors validate to some extent the

12 dataset’s composition. To get a better understanding of where and how the two datasets vary, we also performed a qualitative evaluation. For this we selected a subgraph induced by the 1000 projects with the highest geometric mean score, and visualized the common and non-common elements of the 431 clusters that contained diﬀerent nodes.42 In 301 cases the clusters shared at least one common element. The patterns we encountered mainly concern the following cases: CCFSC links more (and irrelevant) clusters compared to CDSC (e.g. FreeCodeCamp/FreeCodeCamp, gatsbyjs/gatsby, robbyrussell/oh-my- zsh); the converse happens (e.g. leveldb); CCFSC clusters related projects that CDSC does not cluster (e.g. tgstation/tgstation, bitcoin/bitcoin); the converse happens (e.g. hdl qfs, t-s/blex); there is considerable agreement between the two (e.g. Homebrew/homebrew-core with afb/brew); there is considerable agreement but CDSC includes more related projects (e.g. aspnet/Mvc with h2h/Mvc). In general, we noticed that CDSC appears to be more precise at clustering than CCFSC, but worse at naming the clusters.

7 Related Work

In distributed version control and source code management platforms, such as GitHub, developers usually collaborate using the pull request development model [16, 12, 15, 17], according to which repositories are divided into base and forked [25]. This constitutes one of the perils of mining GitHub: a repository is not necessarily a project [25], with commits potentially differing between the associated repositories. Code duplication in GitHub was studied by Lopes et al. [27] through file- level and inter-project analysis of a 4.5 million corpus of non-forked projects. The overlap of files between projects, as given by the files’ token hashes, was computed for certain thresholds and programming languages. JavaScript prevails with 48% of projects having at least 50% of files duplicated in other projects, and 15% of projects being 100% duplicated. Project-level duplication includes appropriations that could be addressed by Git submodules, abandoned derivative development, forks with additional non-source code content, and unorthodox uses of GitHub, such as unpushed changes. Code duplication can hamper the statistical reasoning in random selections of projects, and skew the conclusions of studies performed on them, because the observations (projects) are not independent, and diversity may be com- promised. For the converse problem of obtaining similar GitHub repositories

42Figure 34 and G33.

13 see the recent work by Phuong Nguyen and his colleagues [33] and the references therein. While it is common sense to select a sample that is representative of a population, the importance of diversity is often overlooked, yet as important [4]. Especially in software engineering, where processes of empirical studies often depend on a large number of relevant context variables, general conclusions are difficult to extract [7]. According to Nagappan et al. [32], to provide a good sample coverage, selected projects should be diverse rather than similar to each other. Meanwhile, increasing the sample size does not necessarily increase generality when projects are not carefully selected. Markovtsev and Kant in their work regarding topic modeling of public repositories using names in source code [29], recognized that duplicate projects contain few original changes and may introduce noise into the over- all names distribution. To exclude them and accelerate the training time of the topic model, they applied Locality Sensitive Hashing [26] on the bag- of-words model. According to the analysis, duplicate repositories usually involve web sites, such as github.io, blogs and Linux-based firmwares, which align with our observations. A duplication issue was also identified by Irolla and Dey [23] in the Drebin dataset [5], which is often used to assess the performance of malware detectors [34, 18] and classifiers [19, 38]. Half of the samples in the dataset have other duplicate repackaged versions of the same sequence of opcode. Consequently, a major part of the testing set may also be found in the training, inflating the performance of the designed algorithms. Experiments on classification algorithms trained on the Drebin dataset by including and excluding duplicates suggested moderate to strong underrated inaccuracy, and variation in the performance of the algorithms. Similarly, Allamanis examined the adverse effects of code duplication in machine learning models of code [2]. By comparing models trained on duplicated and deduplicated code corpora, Allamanis concluded that performance metrics, from a user’s perspective, may be up to 100% inflated when duplicates are included. The issue mainly applies to code comple- tion [37, 28], type prediction [21, 36] and code summarization [24, 3], where models provide recommendations on new and unseen code.

8 Research and Improvement Ideas

The main purpose of the presented dataset is to improve the quality of GitHub project samples that are used to conduct empirical software en-

14 gineering studies. It would be interesting to see how such duplication af- fects published results by replicating existing studies after deduplicating the projects by means of this dataset. In addition, the dataset can be used for investigating the ecosystem of duplicated projects in terms of activity, duplication methods (forks vs commit pushes), tree depth, currency, or trustworthiness. The dataset can be further improved by including projects from other forges and by applying more sophisticated cleaning algorithms.
