Hardening, release tooling and GPL-3.0 license (M5)
- Load shedding (limits.max_requests), bounded heavy-permit waits (limits.heavy_wait_secs), live request timeout that only covers the start of a response, and git permits held by the blocking job - Styled error pages for panics, timeouts, overload and 405s; 5xx no-store; Cross-Origin-Opener-Policy - Clone requests capped at 64 MiB - gzip only (brotli's per-response memory wasn't worth ~2%); git_parallel defaults to CPUs, at most 8; fat LTO - Tighter systemd sandbox (systemd-analyze security: 1.2) - Release workflow: x86_64 and aarch64 binaries against glibc 2.28, published with install.sh and SHA256SUMS; CI workflow - install.sh: curl | sudo sh installer for the binary, git user, config and systemd unit - Generic example config and Caddyfile; concise README

| 2 | + | Version 3, 29 June 2007 | |
| 3 | + | ||
| 4 | + | Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/> | |
| 5 | + | Everyone is permitted to copy and distribute verbatim copies | |
| 6 | + | of this license document, but changing it is not allowed. | |
| 7 | + | ||
| 8 | + | Preamble | |
| 9 | + | ||
| 10 | + | The GNU General Public License is a free, copyleft license for | |
| 11 | + | software and other kinds of works. | |
| 12 | + | ||
| 13 | + | The licenses for most software and other practical works are designed | |
| 14 | + | to take away your freedom to share and change the works. By contrast, | |
| 15 | + | the GNU General Public License is intended to guarantee your freedom to | |
| 16 | + | share and change all versions of a program--to make sure it remains free | |
| 17 | + | software for all its users. We, the Free Software Foundation, use the | |
| 18 | + | GNU General Public License for most of our software; it applies also to | |
| 19 | + | any other work released this way by its authors. You can apply it to | |
| 20 | + | your programs, too. | |
| 21 | + | ||
| 22 | + | When we speak of free software, we are referring to freedom, not | |
| 23 | + | price. Our General Public Licenses are designed to make sure that you | |
| 24 | + | have the freedom to distribute copies of free software (and charge for | |
| 25 | + | them if you wish), that you receive source code or can get it if you | |
| 26 | + | want it, that you can change the software or use pieces of it in new | |
| 27 | + | free programs, and that you know you can do these things. | |
| 28 | + | ||
| 29 | + | To protect your rights, we need to prevent others from denying you | |
| 30 | + | these rights or asking you to surrender the rights. Therefore, you have | |
| 31 | + | certain responsibilities if you distribute copies of the software, or if | |
| 32 | + | you modify it: responsibilities to respect the freedom of others. | |
| 33 | + | ||
| 34 | + | For example, if you distribute copies of such a program, whether | |
| 35 | + | gratis or for a fee, you must pass on to the recipients the same | |
| 36 | + | freedoms that you received. You must make sure that they, too, receive | |
| 37 | + | or can get the source code. And you must show them these terms so they | |
| 38 | + | know their rights. | |
| 39 | + | ||
| 40 | + | Developers that use the GNU GPL protect your rights with two steps: | |
| 41 | + | (1) assert copyright on the software, and (2) offer you this License | |
| 42 | + | giving you legal permission to copy, distribute and/or modify it. | |
| 43 | + | ||
| 44 | + | For the developers' and authors' protection, the GPL clearly explains | |
| 45 | + | that there is no warranty for this free software. For both users' and | |
| 46 | + | authors' sake, the GPL requires that modified versions be marked as | |
| 47 | + | changed, so that their problems will not be attributed erroneously to | |
| 48 | + | authors of previous versions. | |
| 49 | + | ||
| 50 | + | Some devices are designed to deny users access to install or run | |
| 51 | + | modified versions of the software inside them, although the manufacturer | |
| 52 | + | can do so. This is fundamentally incompatible with the aim of | |
| 53 | + | protecting users' freedom to change the software. The systematic | |
| 54 | + | pattern of such abuse occurs in the area of products for individuals to | |
| 55 | + | use, which is precisely where it is most unacceptable. Therefore, we | |
| 56 | + | have designed this version of the GPL to prohibit the practice for those | |
| 57 | + | products. If such problems arise substantially in other domains, we | |
| 58 | + | stand ready to extend this provision to those domains in future versions | |
| 59 | + | of the GPL, as needed to protect the freedom of users. | |
| 60 | + | ||
| 61 | + | Finally, every program is threatened constantly by software patents. | |
| 62 | + | States should not allow patents to restrict development and use of | |
| 63 | + | software on general-purpose computers, but in those that do, we wish to | |
| 64 | + | avoid the special danger that patents applied to a free program could | |
| 65 | + | make it effectively proprietary. To prevent this, the GPL assures that | |
| 66 | + | patents cannot be used to render the program non-free. | |
| 67 | + | ||
| 68 | + | The precise terms and conditions for copying, distribution and | |
| 69 | + | modification follow. | |
| 70 | + | ||
| 71 | + | TERMS AND CONDITIONS | |
| 72 | + | ||
| 73 | + | 0. Definitions. | |
| 74 | + | ||
| 75 | + | "This License" refers to version 3 of the GNU General Public License. | |
| 76 | + | ||
| 77 | + | "Copyright" also means copyright-like laws that apply to other kinds of | |
| 78 | + | works, such as semiconductor masks. | |
| 79 | + | ||
| 80 | + | "The Program" refers to any copyrightable work licensed under this | |
| 81 | + | License. Each licensee is addressed as "you". "Licensees" and | |
| 82 | + | "recipients" may be individuals or organizations. | |
| 83 | + | ||
| 84 | + | To "modify" a work means to copy from or adapt all or part of the work | |
| 85 | + | in a fashion requiring copyright permission, other than the making of an | |
| 86 | + | exact copy. The resulting work is called a "modified version" of the | |
| 87 | + | earlier work or a work "based on" the earlier work. | |
| 88 | + | ||
| 89 | + | A "covered work" means either the unmodified Program or a work based | |
| 90 | + | on the Program. | |
| 91 | + | ||
| 92 | + | To "propagate" a work means to do anything with it that, without | |
| 93 | + | permission, would make you directly or secondarily liable for | |
| 94 | + | infringement under applicable copyright law, except executing it on a | |
| 95 | + | computer or modifying a private copy. Propagation includes copying, | |
| 96 | + | distribution (with or without modification), making available to the | |
| 97 | + | public, and in some countries other activities as well. | |
| 98 | + | ||
| 99 | + | To "convey" a work means any kind of propagation that enables other | |
| 100 | + | parties to make or receive copies. Mere interaction with a user through | |
| 101 | + | a computer network, with no transfer of a copy, is not conveying. | |
| 102 | + | ||
| 103 | + | An interactive user interface displays "Appropriate Legal Notices" | |
| 104 | + | to the extent that it includes a convenient and prominently visible | |
| 105 | + | feature that (1) displays an appropriate copyright notice, and (2) | |
| 106 | + | tells the user that there is no warranty for the work (except to the | |
| 107 | + | extent that warranties are provided), that licensees may convey the | |
| 108 | + | work under this License, and how to view a copy of this License. If | |
| 109 | + | the interface presents a list of user commands or options, such as a | |
| 110 | + | menu, a prominent item in the list meets this criterion. | |
| 111 | + | ||
| 112 | + | 1. Source Code. | |
| 113 | + | ||
| 114 | + | The "source code" for a work means the preferred form of the work | |
| 115 | + | for making modifications to it. "Object code" means any non-source | |
| 116 | + | form of a work. | |
| 117 | + | ||
| 118 | + | A "Standard Interface" means an interface that either is an official | |
| 119 | + | standard defined by a recognized standards body, or, in the case of | |
| 120 | + | interfaces specified for a particular programming language, one that | |
| 121 | + | is widely used among developers working in that language. | |
| 122 | + | ||
| 123 | + | The "System Libraries" of an executable work include anything, other | |
| 124 | + | than the work as a whole, that (a) is included in the normal form of | |
| 125 | + | packaging a Major Component, but which is not part of that Major | |
| 126 | + | Component, and (b) serves only to enable use of the work with that | |
| 127 | + | Major Component, or to implement a Standard Interface for which an | |
| 128 | + | implementation is available to the public in source code form. A | |
| 129 | + | "Major Component", in this context, means a major essential component | |
| 130 | + | (kernel, window system, and so on) of the specific operating system | |
| 131 | + | (if any) on which the executable work runs, or a compiler used to | |
| 132 | + | produce the work, or an object code interpreter used to run it. | |
| 133 | + | ||
| 134 | + | The "Corresponding Source" for a work in object code form means all | |
| 135 | + | the source code needed to generate, install, and (for an executable | |
| 136 | + | work) run the object code and to modify the work, including scripts to | |
| 137 | + | control those activities. However, it does not include the work's | |
| 138 | + | System Libraries, or general-purpose tools or generally available free | |
| 139 | + | programs which are used unmodified in performing those activities but | |
| 140 | + | which are not part of the work. For example, Corresponding Source | |
| 141 | + | includes interface definition files associated with source files for | |
| 142 | + | the work, and the source code for shared libraries and dynamically | |
| 143 | + | linked subprograms that the work is specifically designed to require, | |
| 144 | + | such as by intimate data communication or control flow between those | |
| 145 | + | subprograms and other parts of the work. | |
| 146 | + | ||
| 147 | + | The Corresponding Source need not include anything that users | |
| 148 | + | can regenerate automatically from other parts of the Corresponding | |
| 149 | + | Source. | |
| 150 | + | ||
| 151 | + | The Corresponding Source for a work in source code form is that | |
| 152 | + | same work. | |
| 153 | + | ||
| 154 | + | 2. Basic Permissions. | |
| 155 | + | ||
| 156 | + | All rights granted under this License are granted for the term of | |
| 157 | + | copyright on the Program, and are irrevocable provided the stated | |
| 158 | + | conditions are met. This License explicitly affirms your unlimited | |
| 159 | + | permission to run the unmodified Program. The output from running a | |
| 160 | + | covered work is covered by this License only if the output, given its | |
| 161 | + | content, constitutes a covered work. This License acknowledges your | |
| 162 | + | rights of fair use or other equivalent, as provided by copyright law. | |
| 163 | + | ||
| 164 | + | You may make, run and propagate covered works that you do not | |
| 165 | + | convey, without conditions so long as your license otherwise remains | |
| 166 | + | in force. You may convey covered works to others for the sole purpose | |
| 167 | + | of having them make modifications exclusively for you, or provide you | |
| 168 | + | with facilities for running those works, provided that you comply with | |
| 169 | + | the terms of this License in conveying all material for which you do | |
| 170 | + | not control copyright. Those thus making or running the covered works | |
| 171 | + | for you must do so exclusively on your behalf, under your direction | |
| 172 | + | and control, on terms that prohibit them from making any copies of | |
| 173 | + | your copyrighted material outside their relationship with you. | |
| 174 | + | ||
| 175 | + | Conveying under any other circumstances is permitted solely under | |
| 176 | + | the conditions stated below. Sublicensing is not allowed; section 10 | |
| 177 | + | makes it unnecessary. | |
| 178 | + | ||
| 179 | + | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. | |
| 180 | + | ||
| 181 | + | No covered work shall be deemed part of an effective technological | |
| 182 | + | measure under any applicable law fulfilling obligations under article | |
| 183 | + | 11 of the WIPO copyright treaty adopted on 20 December 1996, or | |
| 184 | + | similar laws prohibiting or restricting circumvention of such | |
| 185 | + | measures. | |
| 186 | + | ||
| 187 | + | When you convey a covered work, you waive any legal power to forbid | |
| 188 | + | circumvention of technological measures to the extent such circumvention | |
| 189 | + | is effected by exercising rights under this License with respect to | |
| 190 | + | the covered work, and you disclaim any intention to limit operation or | |
| 191 | + | modification of the work as a means of enforcing, against the work's | |
| 192 | + | users, your or third parties' legal rights to forbid circumvention of | |
| 193 | + | technological measures. | |
| 194 | + | ||
| 195 | + | 4. Conveying Verbatim Copies. | |
| 196 | + | ||
| 197 | + | You may convey verbatim copies of the Program's source code as you | |
| 198 | + | receive it, in any medium, provided that you conspicuously and | |
| 199 | + | appropriately publish on each copy an appropriate copyright notice; | |
| 200 | + | keep intact all notices stating that this License and any | |
| 201 | + | non-permissive terms added in accord with section 7 apply to the code; | |
| 202 | + | keep intact all notices of the absence of any warranty; and give all | |
| 203 | + | recipients a copy of this License along with the Program. | |
| 204 | + | ||
| 205 | + | You may charge any price or no price for each copy that you convey, | |
| 206 | + | and you may offer support or warranty protection for a fee. | |
| 207 | + | ||
| 208 | + | 5. Conveying Modified Source Versions. | |
| 209 | + | ||
| 210 | + | You may convey a work based on the Program, or the modifications to | |
| 211 | + | produce it from the Program, in the form of source code under the | |
| 212 | + | terms of section 4, provided that you also meet all of these conditions: | |
| 213 | + | ||
| 214 | + | a) The work must carry prominent notices stating that you modified | |
| 215 | + | it, and giving a relevant date. | |
| 216 | + | ||
| 217 | + | b) The work must carry prominent notices stating that it is | |
| 218 | + | released under this License and any conditions added under section | |
| 219 | + | 7. This requirement modifies the requirement in section 4 to | |
| 220 | + | "keep intact all notices". | |
| 221 | + | ||
| 222 | + | c) You must license the entire work, as a whole, under this | |
| 223 | + | License to anyone who comes into possession of a copy. This | |
| 224 | + | License will therefore apply, along with any applicable section 7 | |
| 225 | + | additional terms, to the whole of the work, and all its parts, | |
| 226 | + | regardless of how they are packaged. This License gives no | |
| 227 | + | permission to license the work in any other way, but it does not | |
| 228 | + | invalidate such permission if you have separately received it. | |
| 229 | + | ||
| 230 | + | d) If the work has interactive user interfaces, each must display | |
| 231 | + | Appropriate Legal Notices; however, if the Program has interactive | |
| 232 | + | interfaces that do not display Appropriate Legal Notices, your | |
| 233 | + | work need not make them do so. | |
| 234 | + | ||
| 235 | + | A compilation of a covered work with other separate and independent | |
| 236 | + | works, which are not by their nature extensions of the covered work, | |
| 237 | + | and which are not combined with it such as to form a larger program, | |
| 238 | + | in or on a volume of a storage or distribution medium, is called an | |
| 239 | + | "aggregate" if the compilation and its resulting copyright are not | |
| 240 | + | used to limit the access or legal rights of the compilation's users | |
| 241 | + | beyond what the individual works permit. Inclusion of a covered work | |
| 242 | + | in an aggregate does not cause this License to apply to the other | |
| 243 | + | parts of the aggregate. | |
| 244 | + | ||
| 245 | + | 6. Conveying Non-Source Forms. | |
| 246 | + | ||
| 247 | + | You may convey a covered work in object code form under the terms | |
| 248 | + | of sections 4 and 5, provided that you also convey the | |
| 249 | + | machine-readable Corresponding Source under the terms of this License, | |
| 250 | + | in one of these ways: | |
| 251 | + | ||
| 252 | + | a) Convey the object code in, or embodied in, a physical product | |
| 253 | + | (including a physical distribution medium), accompanied by the | |
| 254 | + | Corresponding Source fixed on a durable physical medium | |
| 255 | + | customarily used for software interchange. | |
| 256 | + | ||
| 257 | + | b) Convey the object code in, or embodied in, a physical product | |
| 258 | + | (including a physical distribution medium), accompanied by a | |
| 259 | + | written offer, valid for at least three years and valid for as | |
| 260 | + | long as you offer spare parts or customer support for that product | |
| 261 | + | model, to give anyone who possesses the object code either (1) a | |
| 262 | + | copy of the Corresponding Source for all the software in the | |
| 263 | + | product that is covered by this License, on a durable physical | |
| 264 | + | medium customarily used for software interchange, for a price no | |
| 265 | + | more than your reasonable cost of physically performing this | |
| 266 | + | conveying of source, or (2) access to copy the | |
| 267 | + | Corresponding Source from a network server at no charge. | |
| 268 | + | ||
| 269 | + | c) Convey individual copies of the object code with a copy of the | |
| 270 | + | written offer to provide the Corresponding Source. This | |
| 271 | + | alternative is allowed only occasionally and noncommercially, and | |
| 272 | + | only if you received the object code with such an offer, in accord | |
| 273 | + | with subsection 6b. | |
| 274 | + | ||
| 275 | + | d) Convey the object code by offering access from a designated | |
| 276 | + | place (gratis or for a charge), and offer equivalent access to the | |
| 277 | + | Corresponding Source in the same way through the same place at no | |
| 278 | + | further charge. You need not require recipients to copy the | |
| 279 | + | Corresponding Source along with the object code. If the place to | |
| 280 | + | copy the object code is a network server, the Corresponding Source | |
| 281 | + | may be on a different server (operated by you or a third party) | |
| 282 | + | that supports equivalent copying facilities, provided you maintain | |
| 283 | + | clear directions next to the object code saying where to find the | |
| 284 | + | Corresponding Source. Regardless of what server hosts the | |
| 285 | + | Corresponding Source, you remain obligated to ensure that it is | |
| 286 | + | available for as long as needed to satisfy these requirements. | |
| 287 | + | ||
| 288 | + | e) Convey the object code using peer-to-peer transmission, provided | |
| 289 | + | you inform other peers where the object code and Corresponding | |
| 290 | + | Source of the work are being offered to the general public at no | |
| 291 | + | charge under subsection 6d. | |
| 292 | + | ||
| 293 | + | A separable portion of the object code, whose source code is excluded | |
| 294 | + | from the Corresponding Source as a System Library, need not be | |
| 295 | + | included in conveying the object code work. | |
| 296 | + | ||
| 297 | + | A "User Product" is either (1) a "consumer product", which means any | |
| 298 | + | tangible personal property which is normally used for personal, family, | |
| 299 | + | or household purposes, or (2) anything designed or sold for incorporation | |
| 300 | + | into a dwelling. In determining whether a product is a consumer product, | |
| 301 | + | doubtful cases shall be resolved in favor of coverage. For a particular | |
| 302 | + | product received by a particular user, "normally used" refers to a | |
| 303 | + | typical or common use of that class of product, regardless of the status | |
| 304 | + | of the particular user or of the way in which the particular user | |
| 305 | + | actually uses, or expects or is expected to use, the product. A product | |
| 306 | + | is a consumer product regardless of whether the product has substantial | |
| 307 | + | commercial, industrial or non-consumer uses, unless such uses represent | |
| 308 | + | the only significant mode of use of the product. | |
| 309 | + | ||
| 310 | + | "Installation Information" for a User Product means any methods, | |
| 311 | + | procedures, authorization keys, or other information required to install | |
| 312 | + | and execute modified versions of a covered work in that User Product from | |
| 313 | + | a modified version of its Corresponding Source. The information must | |
| 314 | + | suffice to ensure that the continued functioning of the modified object | |
| 315 | + | code is in no case prevented or interfered with solely because | |
| 316 | + | modification has been made. | |
| 317 | + | ||
| 318 | + | If you convey an object code work under this section in, or with, or | |
| 319 | + | specifically for use in, a User Product, and the conveying occurs as | |
| 320 | + | part of a transaction in which the right of possession and use of the | |
| 321 | + | User Product is transferred to the recipient in perpetuity or for a | |
| 322 | + | fixed term (regardless of how the transaction is characterized), the | |
| 323 | + | Corresponding Source conveyed under this section must be accompanied | |
| 324 | + | by the Installation Information. But this requirement does not apply | |
| 325 | + | if neither you nor any third party retains the ability to install | |
| 326 | + | modified object code on the User Product (for example, the work has | |
| 327 | + | been installed in ROM). | |
| 328 | + | ||
| 329 | + | The requirement to provide Installation Information does not include a | |
| 330 | + | requirement to continue to provide support service, warranty, or updates | |
| 331 | + | for a work that has been modified or installed by the recipient, or for | |
| 332 | + | the User Product in which it has been modified or installed. Access to a | |
| 333 | + | network may be denied when the modification itself materially and | |
| 334 | + | adversely affects the operation of the network or violates the rules and | |
| 335 | + | protocols for communication across the network. | |
| 336 | + | ||
| 337 | + | Corresponding Source conveyed, and Installation Information provided, | |
| 338 | + | in accord with this section must be in a format that is publicly | |
| 339 | + | documented (and with an implementation available to the public in | |
| 340 | + | source code form), and must require no special password or key for | |
| 341 | + | unpacking, reading or copying. | |
| 342 | + | ||
| 343 | + | 7. Additional Terms. | |
| 344 | + | ||
| 345 | + | "Additional permissions" are terms that supplement the terms of this | |
| 346 | + | License by making exceptions from one or more of its conditions. | |
| 347 | + | Additional permissions that are applicable to the entire Program shall | |
| 348 | + | be treated as though they were included in this License, to the extent | |
| 349 | + | that they are valid under applicable law. If additional permissions | |
| 350 | + | apply only to part of the Program, that part may be used separately | |
| 351 | + | under those permissions, but the entire Program remains governed by | |
| 352 | + | this License without regard to the additional permissions. | |
| 353 | + | ||
| 354 | + | When you convey a copy of a covered work, you may at your option | |
| 355 | + | remove any additional permissions from that copy, or from any part of | |
| 356 | + | it. (Additional permissions may be written to require their own | |
| 357 | + | removal in certain cases when you modify the work.) You may place | |
| 358 | + | additional permissions on material, added by you to a covered work, | |
| 359 | + | for which you have or can give appropriate copyright permission. | |
| 360 | + | ||
| 361 | + | Notwithstanding any other provision of this License, for material you | |
| 362 | + | add to a covered work, you may (if authorized by the copyright holders of | |
| 363 | + | that material) supplement the terms of this License with terms: | |
| 364 | + | ||
| 365 | + | a) Disclaiming warranty or limiting liability differently from the | |
| 366 | + | terms of sections 15 and 16 of this License; or | |
| 367 | + | ||
| 368 | + | b) Requiring preservation of specified reasonable legal notices or | |
| 369 | + | author attributions in that material or in the Appropriate Legal | |
| 370 | + | Notices displayed by works containing it; or | |
| 371 | + | ||
| 372 | + | c) Prohibiting misrepresentation of the origin of that material, or | |
| 373 | + | requiring that modified versions of such material be marked in | |
| 374 | + | reasonable ways as different from the original version; or | |
| 375 | + | ||
| 376 | + | d) Limiting the use for publicity purposes of names of licensors or | |
| 377 | + | authors of the material; or | |
| 378 | + | ||
| 379 | + | e) Declining to grant rights under trademark law for use of some | |
| 380 | + | trade names, trademarks, or service marks; or | |
| 381 | + | ||
| 382 | + | f) Requiring indemnification of licensors and authors of that | |
| 383 | + | material by anyone who conveys the material (or modified versions of | |
| 384 | + | it) with contractual assumptions of liability to the recipient, for | |
| 385 | + | any liability that these contractual assumptions directly impose on | |
| 386 | + | those licensors and authors. | |
| 387 | + | ||
| 388 | + | All other non-permissive additional terms are considered "further | |
| 389 | + | restrictions" within the meaning of section 10. If the Program as you | |
| 390 | + | received it, or any part of it, contains a notice stating that it is | |
| 391 | + | governed by this License along with a term that is a further | |
| 392 | + | restriction, you may remove that term. If a license document contains | |
| 393 | + | a further restriction but permits relicensing or conveying under this | |
| 394 | + | License, you may add to a covered work material governed by the terms | |
| 395 | + | of that license document, provided that the further restriction does | |
| 396 | + | not survive such relicensing or conveying. | |
| 397 | + | ||
| 398 | + | If you add terms to a covered work in accord with this section, you | |
| 399 | + | must place, in the relevant source files, a statement of the | |
| 400 | + | additional terms that apply to those files, or a notice indicating | |
| 401 | + | where to find the applicable terms. | |
| 402 | + | ||
| 403 | + | Additional terms, permissive or non-permissive, may be stated in the | |
| 404 | + | form of a separately written license, or stated as exceptions; | |
| 405 | + | the above requirements apply either way. | |
| 406 | + | ||
| 407 | + | 8. Termination. | |
| 408 | + | ||
| 409 | + | You may not propagate or modify a covered work except as expressly | |
| 410 | + | provided under this License. Any attempt otherwise to propagate or | |
| 411 | + | modify it is void, and will automatically terminate your rights under | |
| 412 | + | this License (including any patent licenses granted under the third | |
| 413 | + | paragraph of section 11). | |
| 414 | + | ||
| 415 | + | However, if you cease all violation of this License, then your | |
| 416 | + | license from a particular copyright holder is reinstated (a) | |
| 417 | + | provisionally, unless and until the copyright holder explicitly and | |
| 418 | + | finally terminates your license, and (b) permanently, if the copyright | |
| 419 | + | holder fails to notify you of the violation by some reasonable means | |
| 420 | + | prior to 60 days after the cessation. | |
| 421 | + | ||
| 422 | + | Moreover, your license from a particular copyright holder is | |
| 423 | + | reinstated permanently if the copyright holder notifies you of the | |
| 424 | + | violation by some reasonable means, this is the first time you have | |
| 425 | + | received notice of violation of this License (for any work) from that | |
| 426 | + | copyright holder, and you cure the violation prior to 30 days after | |
| 427 | + | your receipt of the notice. | |
| 428 | + | ||
| 429 | + | Termination of your rights under this section does not terminate the | |
| 430 | + | licenses of parties who have received copies or rights from you under | |
| 431 | + | this License. If your rights have been terminated and not permanently | |
| 432 | + | reinstated, you do not qualify to receive new licenses for the same | |
| 433 | + | material under section 10. | |
| 434 | + | ||
| 435 | + | 9. Acceptance Not Required for Having Copies. | |
| 436 | + | ||
| 437 | + | You are not required to accept this License in order to receive or | |
| 438 | + | run a copy of the Program. Ancillary propagation of a covered work | |
| 439 | + | occurring solely as a consequence of using peer-to-peer transmission | |
| 440 | + | to receive a copy likewise does not require acceptance. However, | |
| 441 | + | nothing other than this License grants you permission to propagate or | |
| 442 | + | modify any covered work. These actions infringe copyright if you do | |
| 443 | + | not accept this License. Therefore, by modifying or propagating a | |
| 444 | + | covered work, you indicate your acceptance of this License to do so. | |
| 445 | + | ||
| 446 | + | 10. Automatic Licensing of Downstream Recipients. | |
| 447 | + | ||
| 448 | + | Each time you convey a covered work, the recipient automatically | |
| 449 | + | receives a license from the original licensors, to run, modify and | |
| 450 | + | propagate that work, subject to this License. You are not responsible | |
| 451 | + | for enforcing compliance by third parties with this License. | |
| 452 | + | ||
| 453 | + | An "entity transaction" is a transaction transferring control of an | |
| 454 | + | organization, or substantially all assets of one, or subdividing an | |
| 455 | + | organization, or merging organizations. If propagation of a covered | |
| 456 | + | work results from an entity transaction, each party to that | |
| 457 | + | transaction who receives a copy of the work also receives whatever | |
| 458 | + | licenses to the work the party's predecessor in interest had or could | |
| 459 | + | give under the previous paragraph, plus a right to possession of the | |
| 460 | + | Corresponding Source of the work from the predecessor in interest, if | |
| 461 | + | the predecessor has it or can get it with reasonable efforts. | |
| 462 | + | ||
| 463 | + | You may not impose any further restrictions on the exercise of the | |
| 464 | + | rights granted or affirmed under this License. For example, you may | |
| 465 | + | not impose a license fee, royalty, or other charge for exercise of | |
| 466 | + | rights granted under this License, and you may not initiate litigation | |
| 467 | + | (including a cross-claim or counterclaim in a lawsuit) alleging that | |
| 468 | + | any patent claim is infringed by making, using, selling, offering for | |
| 469 | + | sale, or importing the Program or any portion of it. | |
| 470 | + | ||
| 471 | + | 11. Patents. | |
| 472 | + | ||
| 473 | + | A "contributor" is a copyright holder who authorizes use under this | |
| 474 | + | License of the Program or a work on which the Program is based. The | |
| 475 | + | work thus licensed is called the contributor's "contributor version". | |
| 476 | + | ||
| 477 | + | A contributor's "essential patent claims" are all patent claims | |
| 478 | + | owned or controlled by the contributor, whether already acquired or | |
| 479 | + | hereafter acquired, that would be infringed by some manner, permitted | |
| 480 | + | by this License, of making, using, or selling its contributor version, | |
| 481 | + | but do not include claims that would be infringed only as a | |
| 482 | + | consequence of further modification of the contributor version. For | |
| 483 | + | purposes of this definition, "control" includes the right to grant | |
| 484 | + | patent sublicenses in a manner consistent with the requirements of | |
| 485 | + | this License. | |
| 486 | + | ||
| 487 | + | Each contributor grants you a non-exclusive, worldwide, royalty-free | |
| 488 | + | patent license under the contributor's essential patent claims, to | |
| 489 | + | make, use, sell, offer for sale, import and otherwise run, modify and | |
| 490 | + | propagate the contents of its contributor version. | |
| 491 | + | ||
| 492 | + | In the following three paragraphs, a "patent license" is any express | |
| 493 | + | agreement or commitment, however denominated, not to enforce a patent | |
| 494 | + | (such as an express permission to practice a patent or covenant not to | |
| 495 | + | sue for patent infringement). To "grant" such a patent license to a | |
| 496 | + | party means to make such an agreement or commitment not to enforce a | |
| 497 | + | patent against the party. | |
| 498 | + | ||
| 499 | + | If you convey a covered work, knowingly relying on a patent license, | |
| 500 | + | and the Corresponding Source of the work is not available for anyone | |
| 501 | + | to copy, free of charge and under the terms of this License, through a | |
| 502 | + | publicly available network server or other readily accessible means, | |
| 503 | + | then you must either (1) cause the Corresponding Source to be so | |
| 504 | + | available, or (2) arrange to deprive yourself of the benefit of the | |
| 505 | + | patent license for this particular work, or (3) arrange, in a manner | |
| 506 | + | consistent with the requirements of this License, to extend the patent | |
| 507 | + | license to downstream recipients. "Knowingly relying" means you have | |
| 508 | + | actual knowledge that, but for the patent license, your conveying the | |
| 509 | + | covered work in a country, or your recipient's use of the covered work | |
| 510 | + | in a country, would infringe one or more identifiable patents in that | |
| 511 | + | country that you have reason to believe are valid. | |
| 512 | + | ||
| 513 | + | If, pursuant to or in connection with a single transaction or | |
| 514 | + | arrangement, you convey, or propagate by procuring conveyance of, a | |
| 515 | + | covered work, and grant a patent license to some of the parties | |
| 516 | + | receiving the covered work authorizing them to use, propagate, modify | |
| 517 | + | or convey a specific copy of the covered work, then the patent license | |
| 518 | + | you grant is automatically extended to all recipients of the covered | |
| 519 | + | work and works based on it. | |
| 520 | + | ||
| 521 | + | A patent license is "discriminatory" if it does not include within | |
| 522 | + | the scope of its coverage, prohibits the exercise of, or is | |
| 523 | + | conditioned on the non-exercise of one or more of the rights that are | |
| 524 | + | specifically granted under this License. You may not convey a covered | |
| 525 | + | work if you are a party to an arrangement with a third party that is | |
| 526 | + | in the business of distributing software, under which you make payment | |
| 527 | + | to the third party based on the extent of your activity of conveying | |
| 528 | + | the work, and under which the third party grants, to any of the | |
| 529 | + | parties who would receive the covered work from you, a discriminatory | |
| 530 | + | patent license (a) in connection with copies of the covered work | |
| 531 | + | conveyed by you (or copies made from those copies), or (b) primarily | |
| 532 | + | for and in connection with specific products or compilations that | |
| 533 | + | contain the covered work, unless you entered into that arrangement, | |
| 534 | + | or that patent license was granted, prior to 28 March 2007. | |
| 535 | + | ||
| 536 | + | Nothing in this License shall be construed as excluding or limiting | |
| 537 | + | any implied license or other defenses to infringement that may | |
| 538 | + | otherwise be available to you under applicable patent law. | |
| 539 | + | ||
| 540 | + | 12. No Surrender of Others' Freedom. | |
| 541 | + | ||
| 542 | + | If conditions are imposed on you (whether by court order, agreement or | |
| 543 | + | otherwise) that contradict the conditions of this License, they do not | |
| 544 | + | excuse you from the conditions of this License. If you cannot convey a | |
| 545 | + | covered work so as to satisfy simultaneously your obligations under this | |
| 546 | + | License and any other pertinent obligations, then as a consequence you may | |
| 547 | + | not convey it at all. For example, if you agree to terms that obligate you | |
| 548 | + | to collect a royalty for further conveying from those to whom you convey | |
| 549 | + | the Program, the only way you could satisfy both those terms and this | |
| 550 | + | License would be to refrain entirely from conveying the Program. | |
| 551 | + | ||
| 552 | + | 13. Use with the GNU Affero General Public License. | |
| 553 | + | ||
| 554 | + | Notwithstanding any other provision of this License, you have | |
| 555 | + | permission to link or combine any covered work with a work licensed | |
| 556 | + | under version 3 of the GNU Affero General Public License into a single | |
| 557 | + | combined work, and to convey the resulting work. The terms of this | |
| 558 | + | License will continue to apply to the part which is the covered work, | |
| 559 | + | but the special requirements of the GNU Affero General Public License, | |
| 560 | + | section 13, concerning interaction through a network will apply to the | |
| 561 | + | combination as such. | |
| 562 | + | ||
| 563 | + | 14. Revised Versions of this License. | |
| 564 | + | ||
| 565 | + | The Free Software Foundation may publish revised and/or new versions of | |
| 566 | + | the GNU General Public License from time to time. Such new versions will | |
| 567 | + | be similar in spirit to the present version, but may differ in detail to | |
| 568 | + | address new problems or concerns. | |
| 569 | + | ||
| 570 | + | Each version is given a distinguishing version number. If the | |
| 571 | + | Program specifies that a certain numbered version of the GNU General | |
| 572 | + | Public License "or any later version" applies to it, you have the | |
| 573 | + | option of following the terms and conditions either of that numbered | |
| 574 | + | version or of any later version published by the Free Software | |
| 575 | + | Foundation. If the Program does not specify a version number of the | |
| 576 | + | GNU General Public License, you may choose any version ever published | |
| 577 | + | by the Free Software Foundation. | |
| 578 | + | ||
| 579 | + | If the Program specifies that a proxy can decide which future | |
| 580 | + | versions of the GNU General Public License can be used, that proxy's | |
| 581 | + | public statement of acceptance of a version permanently authorizes you | |
| 582 | + | to choose that version for the Program. | |
| 583 | + | ||
| 584 | + | Later license versions may give you additional or different | |
| 585 | + | permissions. However, no additional obligations are imposed on any | |
| 586 | + | author or copyright holder as a result of your choosing to follow a | |
| 587 | + | later version. | |
| 588 | + | ||
| 589 | + | 15. Disclaimer of Warranty. | |
| 590 | + | ||
| 591 | + | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY | |
| 592 | + | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT | |
| 593 | + | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY | |
| 594 | + | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, | |
| 595 | + | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR | |
| 596 | + | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM | |
| 597 | + | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF | |
| 598 | + | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. | |
| 599 | + | ||
| 600 | + | 16. Limitation of Liability. | |
| 601 | + | ||
| 602 | + | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
| 603 | + | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS | |
| 604 | + | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY | |
| 605 | + | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE | |
| 606 | + | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF | |
| 607 | + | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD | |
| 608 | + | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), | |
| 609 | + | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF | |
| 610 | + | SUCH DAMAGES. | |
| 611 | + | ||
| 612 | + | 17. Interpretation of Sections 15 and 16. | |
| 613 | + | ||
| 614 | + | If the disclaimer of warranty and limitation of liability provided | |
| 615 | + | above cannot be given local legal effect according to their terms, | |
| 616 | + | reviewing courts shall apply local law that most closely approximates | |
| 617 | + | an absolute waiver of all civil liability in connection with the | |
| 618 | + | Program, unless a warranty or assumption of liability accompanies a | |
| 619 | + | copy of the Program in return for a fee. | |
| 620 | + | ||
| 621 | + | END OF TERMS AND CONDITIONS | |
| 622 | + | ||
| 623 | + | How to Apply These Terms to Your New Programs | |
| 624 | + | ||
| 625 | + | If you develop a new program, and you want it to be of the greatest | |
| 626 | + | possible use to the public, the best way to achieve this is to make it | |
| 627 | + | free software which everyone can redistribute and change under these terms. | |
| 628 | + | ||
| 629 | + | To do so, attach the following notices to the program. It is safest | |
| 630 | + | to attach them to the start of each source file to most effectively | |
| 631 | + | state the exclusion of warranty; and each file should have at least | |
| 632 | + | the "copyright" line and a pointer to where the full notice is found. | |
| 633 | + | ||
| 634 | + | <one line to give the program's name and a brief idea of what it does.> | |
| 635 | + | Copyright (C) <year> <name of author> | |
| 636 | + | ||
| 637 | + | This program is free software: you can redistribute it and/or modify | |
| 638 | + | it under the terms of the GNU General Public License as published by | |
| 639 | + | the Free Software Foundation, either version 3 of the License, or | |
| 640 | + | (at your option) any later version. | |
| 641 | + | ||
| 642 | + | This program is distributed in the hope that it will be useful, | |
| 643 | + | but WITHOUT ANY WARRANTY; without even the implied warranty of | |
| 644 | + | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | |
| 645 | + | GNU General Public License for more details. | |
| 646 | + | ||
| 647 | + | You should have received a copy of the GNU General Public License | |
| 648 | + | along with this program. If not, see <https://www.gnu.org/licenses/>. | |
| 649 | + | ||
| 650 | + | Also add information on how to contact you by electronic and paper mail. | |
| 651 | + | ||
| 652 | + | If the program does terminal interaction, make it output a short | |
| 653 | + | notice like this when it starts in an interactive mode: | |
| 654 | + | ||
| 655 | + | <program> Copyright (C) <year> <name of author> | |
| 656 | + | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. | |
| 657 | + | This is free software, and you are welcome to redistribute it | |
| 658 | + | under certain conditions; type `show c' for details. | |
| 659 | + | ||
| 660 | + | The hypothetical commands `show w' and `show c' should show the appropriate | |
| 661 | + | parts of the General Public License. Of course, your program's commands | |
| 662 | + | might be different; for a GUI interface, you would use an "about box". | |
| 663 | + | ||
| 664 | + | You should also get your employer (if you work as a programmer) or school, | |
| 665 | + | if any, to sign a "copyright disclaimer" for the program, if necessary. | |
| 666 | + | For more information on this, and how to apply and follow the GNU GPL, see | |
| 667 | + | <https://www.gnu.org/licenses/>. | |
| 668 | + | ||
| 669 | + | The GNU General Public License does not permit incorporating your program | |
| 670 | + | into proprietary programs. If your program is a subroutine library, you | |
| 671 | + | may consider it more useful to permit linking proprietary applications with | |
| 672 | + | the library. If this is what you want to do, use the GNU Lesser General | |
| 673 | + | Public License instead of this License. But first, please read | |

| 1 | + | # Ferrenium | |
| 2 | + | ||
| 3 | + | A read-only Git repository browser, like cgit, as a single Rust daemon. It | |
| 4 | + | serves every bare repository under one directory and keeps no state on disk. | |
| 5 | + | ||
| 6 | + | Pages: repo index, summary + README, tree, file (highlighted), raw, log | |
| 7 | + | (path filter, message search), commit + diff, `.patch`, blame, refs, file | |
| 8 | + | finder, `.tar.gz`/`.zip` snapshots, Atom feed. `git clone` over HTTPS | |
| 9 | + | (read-only). | |
| 10 | + | ||
| 11 | + | ## Install | |
| 12 | + | ||
| 13 | + | On a Linux host with systemd (x86_64 or aarch64, glibc 2.28+): | |
| 14 | + | ||
| 15 | + | ```sh | |
| 16 | + | curl -fsSL https://github.com/krolyxon/ferrenium/releases/latest/download/install.sh | sudo FERRENIUM_DOMAIN=git.example.com sh | |
| 17 | + | ``` | |
| 18 | + | ||
| 19 | + | This: | |
| 20 | + | ||
| 21 | + | - downloads the latest release binary, verifies its checksum and installs it to `/usr/local/bin/ferrenium` | |
| 22 | + | - creates the `git` user if it doesn't exist (home `/home/git`, shell `git-shell`) | |
| 23 | + | - writes `/etc/ferrenium/ferrenium.toml` (never overwritten on later runs) | |
| 24 | + | - installs `/etc/systemd/system/ferrenium.service` and runs `systemctl enable --now ferrenium` | |
| 25 | + | ||
| 26 | + | Variables: `FERRENIUM_DOMAIN` (fills `base_url` and clone URLs in a new | |
| 27 | + | config), `FERRENIUM_USER` (default `git`), `FERRENIUM_VERSION` (e.g. | |
| 28 | + | `v0.1.0`, default latest). | |
| 29 | + | ||
| 30 | + | Run the same command again to upgrade: it replaces the binary and unit | |
| 31 | + | and restarts the service. To remove it: `… | sudo sh -s -- --uninstall`. | |
| 32 | + | This keeps `/etc/ferrenium` and the repositories. | |
| 33 | + | ||
| 34 | + | ### The service | |
| 35 | + | ||
| 36 | + | It's a normal system service. The unit has `User=git`, so systemd starts it | |
| 37 | + | as the repo owner. You don't need `su git` or `systemctl --user`. | |
| 38 | + | ||
| 39 | + | ```sh | |
| 40 | + | sudo systemctl status ferrenium | |
| 41 | + | sudo systemctl reload ferrenium # after editing the config | |
| 42 | + | sudo journalctl -u ferrenium -f | |
| 43 | + | sudo systemctl edit ferrenium # overrides; survive upgrades | |
| 44 | + | ``` | |
| 45 | + | ||
| 46 | + | The unit is sandboxed: the filesystem is read-only, there are no | |
| 47 | + | capabilities, a syscall filter applies, and only localhost may connect. | |
| 48 | + | ||
| 49 | + | ### Reverse proxy | |
| 50 | + | ||
| 51 | + | Ferrenium listens on `127.0.0.1:8080` (plain HTTP/1.1). Caddy: | |
| 52 | + | ||
| 53 | + | ```caddy | |
| 54 | + | git.example.com { | |
| 55 | + | reverse_proxy 127.0.0.1:8080 | |
| 56 | + | } | |
| 57 | + | ``` | |
| 58 | + | ||
| 59 | + | If Caddy runs in Docker, use `network_mode: host` so it can reach | |
| 60 | + | `127.0.0.1`. | |
| 61 | + | ||
| 62 | + | ### Repositories | |
| 63 | + | ||
| 64 | + | Put bare repositories anywhere under `/home/git` (up to 3 levels deep). | |
| 65 | + | Ferrenium picks up new repos and pushes within about a second. | |
| 66 | + | ||
| 67 | + | ```sh | |
| 68 | + | sudo -u git git init --bare /home/git/project.git | |
| 69 | + | git push git@git.example.com:project.git main # after adding your key to /home/git/.ssh/authorized_keys | |
| 70 | + | ``` | |
| 71 | + | ||
| 72 | + | ## Configuration | |
| 73 | + | ||
| 74 | + | Edit `/etc/ferrenium/ferrenium.toml`. Every key is optional and unknown | |
| 75 | + | keys are errors. The file lists all keys with their defaults | |
| 76 | + | (`ferrenium example config` prints the same). To validate the config and | |
| 77 | + | list the repositories it finds: | |
| 78 | + | ||
| 79 | + | ```sh | |
| 80 | + | ferrenium check --config /etc/ferrenium/ferrenium.toml | |
| 81 | + | ``` | |
| 82 | + | ||
| 83 | + | `listen`, `base_path`, `compression`, `cache.size_mb` and the `limits.*_parallel`/`max_requests` | |
| 84 | + | settings need a restart; everything else applies on reload. | |
| 85 | + | ||
| 86 | + | Per-repository metadata comes from the first source that sets it: | |
| 87 | + | ||
| 88 | + | 1. `[[repo]]` in the config (`name`, `description`, `section`, `owner`, `hidden`, `readme`, `default_branch`) | |
| 89 | + | 2. the repo's git config: `ferrenium.{description,owner,section,hidden,readme}`, or the gitweb/cgit keys | |
| 90 | + | 3. the repo's `description` file | |
| 91 | + | ||
| 92 | + | ```sh | |
| 93 | + | sudo -u git git -C /home/git/secret.git config ferrenium.hidden true | |
| 94 | + | ``` | |
| 95 | + | ||
| 96 | + | ### Limits | |
| 97 | + | ||
| 98 | + | Defaults are sized for a small VPS: | |
| 99 | + | ||
| 100 | + | | Key | Default | | | |
| 101 | + | |---|---|---| | |
| 102 | + | | `limits.git_parallel` | CPUs, max 8 | concurrent git work | | |
| 103 | + | | `limits.heavy_parallel` | 2 | concurrent blame / archive / clone / log search | | |
| 104 | + | | `limits.heavy_wait_secs` | 10 | queue time for those before `503` | | |
| 105 | + | | `limits.max_requests` | 512 | in-flight requests before `503` | | |
| 106 | + | | `limits.request_timeout_secs` | 30 | until the response starts | | |
| 107 | + | | `limits.diff_files` / `diff_lines` | 300 / 10000 | larger diffs are truncated | | |
| 108 | + | | `ui.max_blob_kb` / `max_highlight_kb` | 1024 / 256 | larger files: raw link / no highlighting | | |
| 109 | + | | `cache.size_mb` | 64 | in-memory cache | | |
| 110 | + | ||
| 111 | + | `/robots.txt` keeps crawlers off the expensive pages. Memory use at idle is | |
| 112 | + | about 10 MB. | |
| 113 | + | ||
| 114 | + | ## Building from source | |
| 115 | + | ||
| 116 | + | Requires Rust 1.89+. | |
| 117 | + | ||
| 118 | + | ```sh | |
| 119 | + | cargo build --release # target/release/ferrenium | |
| 120 | + | ferrenium example config|systemd|caddy | |
| 121 | + | ``` | |
| 122 | + | ||
| 123 | + | ## Development | |
| 124 | + | ||
| 125 | + | ```sh | |
| 126 | + | cargo test # needs the git CLI | |
| 127 | + | cargo test --release | |
| 128 | + | cargo clippy --all-targets -- -D warnings | |
| 129 | + | cargo run -- serve --config dev.toml | |
| 130 | + | tools/gen-languages/gen.py # regenerate the Linguist language table | |
| 131 | + | ``` | |
| 132 | + | ||
| 133 | + | To release: bump `version` in `Cargo.toml`, commit, then push a `vX.Y.Z` tag. | |
| 134 | + | The `release` workflow tests, builds x86_64 and aarch64 binaries, and | |
| 135 | + | publishes them with `install.sh` and `SHA256SUMS`. | |
