It is based on [OpenSSL](https://www.openssl.org), a proven and efficient TLS implementation. It is designed for efficiency, speed and compliance. ## Installation ### Dependencies Fast TLS depends on OpenSSL v1.0+. You need OpenSSL development headers to build it. You can check your current OpenSSL version with `openssl version`. ### Generic build You can trigger build with: ./configure && make ### OSX build example On macOS the system copy of OpenSSL is usually too old, so you need to install a newer OpenSSL version. You can install OpenSSL with Homebrew: brew install openssl You can then export environment variables to use OpenSSL as installed by Homebrew, before issuing compilation commands: export LDFLAGS="-L/usr/local/opt/openssl/lib" export CFLAGS="-I/usr/local/opt/openssl/include/" export CPPFLAGS="-I/usr/local/opt/openssl/include/" ./configure && make ## Development ### Test #### Unit test You can run eunit test with the command: make test fast_tls-1.1.3/vars.config.in0000644000232200023220000000023113605316475016456 0ustar debalancedebalance{cflags, "@CFLAGS@"}. {ldflags, "@LDFLAGS@"}. {with_gcov, "@gcov@"}. %% Local Variables: %% mode: erlang %% End: %% vim: set filetype=erlang tabstop=8: fast_tls-1.1.3/rebar.config.script0000644000232200023220000001172713605316475017510 0ustar debalancedebalance%%%---------------------------------------------------------------------- %%% File : rebar.config %%% Author : Mickael Remond %%% Purpose : Rebar build script.

First, keep in mind that we're calculating the ideal * maximum chain length based on the *new* (doubled) bucket count. * In fractions this is just n/b (n=number of items,b=new num buckets). * Since the ideal chain length is an integer, we want to calculate * ceil(n/b). We don't depend on floating point arithmetic in this * hash, so to calculate ceil(n/b) with integers we could write * * ceil(n/b) = (n/b) + ((n%b)?1:0) * * and in fact a previous version of this hash did just that. * But now we have improved things a bit by recognizing that b is * always a power of two. We keep its base 2 log handy (call it lb), * so now we can write this with a bit shift and logical AND: * * ceil(n/b) = (n>>lb) + ( (n & (b-1)) ? 1:0) * */ #define HASH_EXPAND_BUCKETS(hh,tbl,oomed) \ do { \ unsigned _he_bkt; \ unsigned _he_bkt_i; \ struct UT_hash_handle *_he_thh, *_he_hh_nxt; \ UT_hash_bucket *_he_new_buckets, *_he_newbkt; \ _he_new_buckets = (UT_hash_bucket*)uthash_malloc( \ 2UL * (tbl)->num_buckets * sizeof(struct UT_hash_bucket)); \ if (!_he_new_buckets) { \ HASH_RECORD_OOM(oomed); \ } else { \ uthash_bzero(_he_new_buckets, \ 2UL * (tbl)->num_buckets * sizeof(struct UT_hash_bucket)); \ (tbl)->ideal_chain_maxlen = \ ((tbl)->num_items >> ((tbl)->log2_num_buckets+1U)) + \ ((((tbl)->num_items & (((tbl)->num_buckets*2U)-1U)) != 0U) ? 1U : 0U); \ (tbl)->nonideal_items = 0; \ for (_he_bkt_i = 0; _he_bkt_i < (tbl)->num_buckets; _he_bkt_i++) { \ _he_thh = (tbl)->buckets[ _he_bkt_i ].hh_head; \ while (_he_thh != NULL) { \ _he_hh_nxt = _he_thh->hh_next; \ HASH_TO_BKT(_he_thh->hashv, (tbl)->num_buckets * 2U, _he_bkt); \ _he_newbkt = &(_he_new_buckets[_he_bkt]); \ if (++(_he_newbkt->count) > (tbl)->ideal_chain_maxlen) { \ (tbl)->nonideal_items++; \ _he_newbkt->expand_mult = _he_newbkt->count / (tbl)->ideal_chain_maxlen; \ } \ _he_thh->hh_prev = NULL; \ _he_thh->hh_next = _he_newbkt->hh_head; \ if (_he_newbkt->hh_head != NULL) { \ _he_newbkt->hh_head->hh_prev = _he_thh; \ } \ _he_newbkt->hh_head = _he_thh; \ _he_thh = _he_hh_nxt; \ } \ } \ uthash_free((tbl)->buckets, (tbl)->num_buckets * sizeof(struct UT_hash_bucket)); \ (tbl)->num_buckets *= 2U; \ (tbl)->log2_num_buckets++; \ (tbl)->buckets = _he_new_buckets; \ (tbl)->ineff_expands = ((tbl)->nonideal_items > ((tbl)->num_items >> 1)) ? \ ((tbl)->ineff_expands+1U) : 0U; \ if ((tbl)->ineff_expands > 1U) { \ (tbl)->noexpand = 1; \ uthash_noexpand_fyi(tbl); \ } \ uthash_expand_fyi(tbl); \ } \ } while (0) /* This is an adaptation of Simon Tatham's O(n log(n)) mergesort */ /* Note that HASH_SORT assumes the hash handle name to be hh. * HASH_SRT was added to allow the hash handle name to be passed in. */ #define HASH_SORT(head,cmpfcn) HASH_SRT(hh,head,cmpfcn) #define HASH_SRT(hh,head,cmpfcn) \ do { \ unsigned _hs_i; \ unsigned _hs_looping,_hs_nmerges,_hs_insize,_hs_psize,_hs_qsize; \ struct UT_hash_handle *_hs_p, *_hs_q, *_hs_e, *_hs_list, *_hs_tail; \ if (head != NULL) { \ _hs_insize = 1; \ _hs_looping = 1; \ _hs_list = &((head)->hh); \ while (_hs_looping != 0U) { \ _hs_p = _hs_list; \ _hs_list = NULL; \ _hs_tail = NULL; \ _hs_nmerges = 0; \ while (_hs_p != NULL) { \ _hs_nmerges++; \ _hs_q = _hs_p; \ _hs_psize = 0; \ for (_hs_i = 0; _hs_i < _hs_insize; ++_hs_i) { \ _hs_psize++; \ _hs_q = ((_hs_q->next != NULL) ? \ HH_FROM_ELMT((head)->hh.tbl, _hs_q->next) : NULL); \ if (_hs_q == NULL) { \ break; \ } \ } \ _hs_qsize = _hs_insize; \ while ((_hs_psize != 0U) || ((_hs_qsize != 0U) && (_hs_q != NULL))) { \ if (_hs_psize == 0U) { \ _hs_e = _hs_q; \ _hs_q = ((_hs_q->next != NULL) ? \ HH_FROM_ELMT((head)->hh.tbl, _hs_q->next) : NULL); \ _hs_qsize--; \ } else if ((_hs_qsize == 0U) || (_hs_q == NULL)) { \ _hs_e = _hs_p; \ if (_hs_p != NULL) { \ _hs_p = ((_hs_p->next != NULL) ? \ HH_FROM_ELMT((head)->hh.tbl, _hs_p->next) : NULL); \ } \ _hs_psize--; \ } else if ((cmpfcn( \ DECLTYPE(head)(ELMT_FROM_HH((head)->hh.tbl, _hs_p)), \ DECLTYPE(head)(ELMT_FROM_HH((head)->hh.tbl, _hs_q)) \ )) <= 0) { \ _hs_e = _hs_p; \ if (_hs_p != NULL) { \ _hs_p = ((_hs_p->next != NULL) ? \ HH_FROM_ELMT((head)->hh.tbl, _hs_p->next) : NULL); \ } \ _hs_psize--; \ } else { \ _hs_e = _hs_q; \ _hs_q = ((_hs_q->next != NULL) ? \ HH_FROM_ELMT((head)->hh.tbl, _hs_q->next) : NULL); \ _hs_qsize--; \ } \ if ( _hs_tail != NULL ) { \ _hs_tail->next = ((_hs_e != NULL) ? \ ELMT_FROM_HH((head)->hh.tbl, _hs_e) : NULL); \ } else { \ _hs_list = _hs_e; \ } \ if (_hs_e != NULL) { \ _hs_e->prev = ((_hs_tail != NULL) ? \ ELMT_FROM_HH((head)->hh.tbl, _hs_tail) : NULL); \ } \ _hs_tail = _hs_e; \ } \ _hs_p = _hs_q; \ } \ if (_hs_tail != NULL) { \ _hs_tail->next = NULL; \ } \ if (_hs_nmerges <= 1U) { \ _hs_looping = 0; \ (head)->hh.tbl->tail = _hs_tail; \ DECLTYPE_ASSIGN(head, ELMT_FROM_HH((head)->hh.tbl, _hs_list)); \ } \ _hs_insize *= 2U; \ } \ HASH_FSCK(hh, head, "HASH_SRT"); \ } \ } while (0) /* This function selects items from one hash into another hash. * The end result is that the selected items have dual presence * in both hashes.

Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful. ## Scope This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers. ## Enforcement Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at contact@process-one.net. All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately. Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership. ## Attribution This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html [homepage]: https://www.contributor-covenant.org For answers to common questions about this code of conduct, see https://www.contributor-covenant.org/faq fast_tls-1.1.3/CONTRIBUTING.md0000644000232200023220000001361513605316475016152 0ustar debalancedebalance# Contributing We'd love for you to contribute to our source code and to make our project even better than it is today! Here are the guidelines we'd like you to follow: * [Code of Conduct](#coc) * [Questions and Problems](#question) * [Issues and Bugs](#issue) * [Feature Requests](#feature) * [Issue Submission Guidelines](#submit) * [Pull Request Submission Guidelines](#submit-pr) * [Signing the CLA](#cla) ## Code of Conduct Help us keep our community open-minded and inclusive. Please read and follow our [Code of Conduct][coc]. ## Questions, Bugs, Features ### Got a Question or Problem? Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests. You've got much better chances of getting your question answered on dedicated support platforms, the best being [Stack Overflow][stackoverflow]. Stack Overflow is a much better place to ask questions since: - there are thousands of people willing to help on Stack Overflow - questions and answers stay available for public viewing so your question / answer might help someone else - Stack Overflow's voting system assures that the best answers are prominently visible. To save your and our time, we will systematically close all issues that are requests for general support and redirect people to the section you are reading right now. ### Found an Issue or Bug? If you find a bug in the source code, you can help us by submitting an issue to our [GitHub Repository][github]. Even better, you can submit a Pull Request with a fix. ### Missing a Feature? You can request a new feature by submitting an issue to our [GitHub Repository][github-issues]. If you would like to implement a new feature then consider what kind of change it is: * **Major Changes** that you wish to contribute to the project should be discussed first in an [GitHub issue][github-issues] that clearly outlines the changes and benefits of the feature. * **Small Changes** can directly be crafted and submitted to the [GitHub Repository][github] as a Pull Request. See the section about [Pull Request Submission Guidelines](#submit-pr). ## Issue Submission Guidelines Before you submit your issue search the archive, maybe your question was already answered. If your issue appears to be a bug, and hasn't been reported, open a new issue. Help us to maximize the effort we can spend fixing issues and adding new features, by not reporting duplicate issues. The "[new issue][github-new-issue]" form contains a number of prompts that you should fill out to make it easier to understand and categorize the issue. ## Pull Request Submission Guidelines By submitting a pull request for a code or doc contribution, you need to have the right to grant your contribution's copyright license to ProcessOne. Please check [ProcessOne CLA][cla] for details. Before you submit your pull request consider the following guidelines: * Search [GitHub][github-pr] for an open or closed Pull Request that relates to your submission. You don't want to duplicate effort. * Make your changes in a new git branch: ```shell git checkout -b my-fix-branch master ``` * Test your changes and, if relevant, expand the automated test suite. * Create your patch commit, including appropriate test cases. * If the changes affect public APIs, change or add relevant documentation. * Commit your changes using a descriptive commit message. ```shell git commit -a ``` Note: the optional commit `-a` command line option will automatically "add" and "rm" edited files. * Push your branch to GitHub: ```shell git push origin my-fix-branch ``` * In GitHub, send a pull request to `master` branch. This will trigger the continuous integration and run the test. We will also notify you if you have not yet signed the [contribution agreement][cla]. * If you find that the continunous integration has failed, look into the logs to find out if your changes caused test failures, the commit message was malformed etc. If you find that the tests failed or times out for unrelated reasons, you can ping a team member so that the build can be restarted. * If we suggest changes, then: * Make the required updates. * Test your changes and test cases. * Commit your changes to your branch (e.g. `my-fix-branch`). * Push the changes to your GitHub repository (this will update your Pull Request). You can also amend the initial commits and force push them to the branch. ```shell git rebase master -i git push origin my-fix-branch -f ``` This is generally easier to follow, but separate commits are useful if the Pull Request contains iterations that might be interesting to see side-by-side. That's it! Thank you for your contribution! ## Signing the Contributor License Agreement (CLA) Upon submitting a Pull Request, we will ask you to sign our CLA if you haven't done so before. It's a quick process, we promise, and you will be able to do it all online You can read [ProcessOne Contribution License Agreement][cla] in PDF. This is part of the legal framework of the open-source ecosystem that adds some red tape, but protects both the contributor and the company / foundation behind the project. It also gives us the option to relicense the code with a more permissive license in the future.
