[ { "path": ".cursor/skills/graphite-pr-workflow/SKILL.md", "content": "---\nname: graphite-pr-workflow\ndescription: Create branches, commits, and pull requests using Graphite CLI (gt) for the snowflake-jdbc repository. Use when the user asks to create a PR, submit a PR, commit changes, or push a branch. Covers Graphite commands, SNOW-ticket commit message conventions, PR description templates, and snowflake-jdbc-specific pre-commit formatting/checkstyle requirements.\n---\n\n# Graphite PR Workflow (snowflake-jdbc)\n\n## CRITICAL: Do Not Commit or Submit Without Explicit Instruction\n\n**NEVER run `gt commit create`, `git commit`, `gt submit`, or open a PR unless the user has explicitly asked you to.** Completing a feature is NOT permission to commit. Passing tests is NOT permission to commit. Pre-commit checks succeeding is NOT permission to commit.\n\nWhen you have finished implementing a feature or change, you MAY ask the user whether they want you to proceed with creating a commit and PR. Phrase it as a question and wait for explicit confirmation before doing anything that mutates git history or the remote.\n\nExamples of acceptable prompts after finishing work:\n- \"The change is implemented and tests pass. Would you like me to format, run checkstyle, and create a commit + PR?\"\n- \"Should I proceed with `gt commit create` and `gt submit`?\"\n\nDo NOT interpret ambiguous responses (\"looks good\", \"great\", \"thanks\") as approval to commit. Wait for an explicit \"yes, commit\" / \"create the PR\" / \"go ahead and submit\".\n\n## Required Pre-Commit Checks (snowflake-jdbc)\n\nBefore running ANY commit command (`gt commit create`, `git commit`, `gt commit amend`), you MUST run the following two Maven commands in order from the repo root and confirm they succeed:\n\n1. **Format the code** with the Spotify fmt plugin:\n\n ```bash\n mvn com.spotify.fmt:fmt-maven-plugin:format\n ```\n\n2. **Validate checkstyle** passes cleanly:\n\n ```bash\n mvn clean validate --batch-mode --show-version -P check-style\n ```\n\nIf either command fails, fix the reported issues (re-running the formatter for any new files, or addressing checkstyle violations manually) and re-run both commands until both succeed. Only then may you proceed with committing — and only if the user has explicitly asked you to commit (see section above).\n\n## Commit Message Convention\n\nPrefix with Jira ticket: `SNOW-{ticket}: {description}`\n\n```\nSNOW-3254915: Add QueryStatus enum and is_still_running/is_an_error static methods\n```\n\nUse `NO-SNOW:` for changes without a ticket.\n\n## Creating a PR (only after explicit user approval)\n\n```bash\n# 1. Create a tracked branch\ngt branch create {user}/{branch-name}\n\n# 2. Format and validate (REQUIRED before staging/committing — see Pre-Commit Checks above)\nmvn com.spotify.fmt:fmt-maven-plugin:format\nmvn clean validate --batch-mode --show-version -P check-style\n\n# 3. Stage files\ngit add \n\n# 4. Commit (runs pre-commit hooks)\ngt commit create -m \"SNOW-{ticket}: {description}\"\n\n# 5. Push and create PR (draft mode in non-interactive)\ngt submit --no-edit\n```\n\nThen update title/description via `gh pr edit` or the Graphite web UI.\n\n## PR Description Template\n\n```markdown\n## Summary\n- Bullet points describing what changed and why\n\n## Context\nBrief explanation of how this fits into the larger effort (e.g., \"first of two PRs for...\")\n\n## Test plan\nExplain how the change was tested: what commands were run, what was\nverified, and the results. Be specific to this PR.\n```\n\n## Key Commands\n\n| Command | Purpose |\n|---------|---------|\n| `mvn com.spotify.fmt:fmt-maven-plugin:format` | Auto-format Java sources (REQUIRED before commit) |\n| `mvn clean validate --batch-mode --show-version -P check-style` | Run checkstyle validation (REQUIRED before commit) |\n| `gt branch create {user}/{branch-name}` | Create branch tracked by Graphite |\n| `gt commit create -m \"...\"` | Commit with message |\n| `gt commit amend` | Amend current commit |\n| `gt submit --no-edit` | Push and create/update PR |\n| `gt submit --stack` | Submit entire stack of PRs |\n| `gt restack` | Rebase stack after upstream changes |\n\n## Before Creating a PR: Required Checks\n\nBefore proceeding with branch creation or committing, you MUST:\n\n1. **Confirm the user has explicitly requested a commit/PR.** See the top of this file. Do not commit proactively.\n\n2. **Run the formatter and checkstyle commands** described in the Required Pre-Commit Checks section above and confirm both pass.\n\n3. **Ask for SNOW ticket number** if the user hasn't provided one. Use AskQuestion:\n - Prompt: \"What is the SNOW Jira ticket number for this change?\"\n - Options: a text-free response, or \"NO-SNOW (no ticket)\"\n Do NOT proceed with a commit until the ticket number is confirmed.\n\n4. **Detect stacked PR situation.** Run `git log --oneline main..HEAD` or check `git branch --show-current` and its parent. If the current branch is NOT based directly off `main` (i.e., there are intermediate branches), ask:\n - \"This branch is based off `{parent_branch}`, not `main`. Should this be a stacked PR?\"\n - If yes: use `gt submit --stack` to submit the full stack\n - If no: use `gt submit --no-edit` for just this branch\n\n## Notes\n\n- `gt submit --no-edit` creates PRs in **draft mode** when non-interactive\n- Pre-commit hooks run automatically on `gt commit create`, but they are NOT a substitute for running the formatter + checkstyle commands manually beforehand\n" }, { "path": ".github/CODEOWNERS", "content": "* @snowflakedb/Client\n/src/main/java/net/snowflake/client/core/crl/** @snowflakedb/pki-oversight @snowflakedb/Client\n/src/main/java/net/snowflake/client/core/*TrustManager* @snowflakedb/pki-oversight @snowflakedb/Client\n" }, { "path": ".github/ISSUE_TEMPLATE/BUG_REPORT.md", "content": "---\nname: Bug Report 🐞\nabout: Something isn't working as expected?

id: secret-scanner\n" }, { "path": "CHANGELOG.md", "content": "#### For all official JDBC Release Notes please refer to https://docs.snowflake.com/en/release-notes/clients-drivers/jdbc\n\n# Changelog\n- v4.2.1-SNAPSHOT\n - Fixed path traversal via server-controlled filenames in `SnowflakeFileTransferAgent` GET destination filename derivation; backslash separators are now stripped and traversal/absolute basenames are rejected (snowflakedb/snowflake-jdbc#2622).\n\n- v4.2.0\n - Extended the `SKIP_TOKEN_FILE_PERMISSIONS_VERIFICATION` environment variable to also bypass permission verification on the `connections.toml` config file and on the credential cache file (`credential_cache_v1.json`), unblocking driver use in SPCS environments where strict 0600/0700 ownership cannot be guaranteed (snowflakedb/snowflake-jdbc#2614)\n - Fixed NPE in `RestRequest.sendIBHttpErrorEvent` when `SFSession.getTelemetryClient()` returns null because the session URL is not yet set; a `NoOpTelemetryClient` is now returned instead, allowing the original HTTP error to be surfaced to the caller (snowflakedb/snowflake-jdbc#2610)\n - Added support for attaching the SPCS service-identifier token (`SPCS_TOKEN`) to login requests when the driver is running inside an SPCS container (gated on the `SNOWFLAKE_RUNNING_INSIDE_SPCS` environment variable; token read from `/snowflake/session/spcs_token`) (snowflakedb/snowflake-jdbc#2603)\n - Added libc family and version detection (`LIBC_FAMILY`, `LIBC_VERSION`) to the `CLIENT_ENVIRONMENT` section of the login request on Linux (snowflakedb/snowflake-jdbc#2596)\n - Fixed NPE in `SFTrustManager.validateRevocationStatusMain` when the OCSP cache contains a non-SUCCESSFUL response (e.g. `unauthorized(6)`); the response is now surfaced as an `SFOCSPException` so cache eviction and fail-open run normally (snowflakedb/snowflake-jdbc#2597)\n - Added IPv6 support for cloud metadata services so Workload Identity Federation and platform detection work on IPv6-only instances (snowflakedb/snowflake-jdbc#2586):\n - GCP WIF attestation now uses hostname `metadata.google.internal` instead of the IPv4 link-local address.\n - EC2 instance detection probes the IPv4 and IPv6 IMDS endpoints (`[fd00:ec2::254]`) in parallel so detection succeeds on IPv6-only instances without doubling the detection budget on dual-stack hosts.\n - Added `enableCopyResultSet` connection property (default `false`): when `true`, `Statement.execute()` exposes the COPY INTO per-file metadata result set via `getResultSet()` instead of consuming it internally (snowflakedb/snowflake-jdbc#2592)\n - Migrated CI test images from CentOS 7 (EOL) to Rocky Linux 8 (snowflakedb/snowflake-jdbc#2578)\n - Fixed NPE \"The URI scheme of endpointOverride must not be null\" happening during file transfer (e.g. PUT) in some use-cases (snowflakedb/snowflake-jdbc#2572)\n - Fixed connections.toml auto-configuration behaviour (snowflakedb/snowflake-jdbc#2591):\n - now defaulting to port 443 instead of 80 when neither port nor protocol is specified\n - config coming from the JDBC connection string are no longer ignored when auto-configuration sourced items also present (when both present, direct connection config takes precedence)\n - Fixed protocol field in connections.toml being ignored, causing connections to always use HTTPS (snowflakedb/snowflake-jdbc#2585)\n - Fixed SecurityException on credential cache file ownership check in containers where JVM returns '?' for user.name (snowflakedb/snowflake-jdbc#2600).\n - Fixed credential cache delete operations ignoring clientStoreTemporaryCredential=false setting (snowflakedb/snowflake-jdbc#2600).\n - Fixed S3 transfer thread pool leak during repeated PUT/GET operations causing possible OOM (snowflakedb/snowflake-jdbc#2602).\n - Bumped BouncyCastle to 1.84 to address CVE-2026-0636, CVE-2026-5588, and CVE-2026-5598 (snowflakedb/snowflake-jdbc#2593).\n - Added `workloadIdentityAwsExternalId` connection property to support AWS STS external ID in Workload Identity Federation role-chaining flows (snowflakedb/snowflake-jdbc#2565).\n - Bumped grpc-java to 1.81.1 now that they also upgraded to netty 4.1.132.Final as the second part of PR 2561, and also netty itself to 4.1.133.Final to address several CVE (snowflakedb/snowflake-jdbc#2611).\n\n- v4.1.0\n - Added warning about using plain HTTP OAuth endpoints (snowflakedb/snowflake-jdbc#2556).\n - Fix initializing ObjectMapper when DATE_OUTPUT_FORMAT is specified (snowflakedb/snowflake-jdbc#2545).\n - Fix Netty native library conflict in thin JAR (snowflakedb/snowflake-jdbc#2559)\n - Bumped netty to 4.1.132.Final to address CVE-2026-33870 (High) and CVE-2026-33871 (High) (snowflakedb/snowflake-jdbc#2561)\n - Added getRole, getWarehouse and getDatabase API extension methods (snowflakedb/snowflake-jdbc#2564)\n - Fix driver failure when security manager prohibits access to system properties, environment variables and modifying security providers (snowflakedb/snowflake-jdbc#2563)\n - Removed the io.netty.tryReflectionSetAccessible system property setting as it's no longer needed with modern Arrow/Netty versions (snowflakedb/snowflake-jdbc#2563)\n - Fixed crash in getColumns operation when table contained unrecognised column type (snowflakedb/snowflake-jdbc#2568).\n - Fixed session expiration when multiple sessions have different heartbeat intervals (snowflakedb/snowflake-jdbc#2566).\n - Merge QueryContext from failed query responses (snowflakedb/snowflake-jdbc#2570)\n\n- v4.0.2\n - Fix expired session token renewal when polling results (snowflakedb/snowflake-jdbc#2489) \n - Fix missing minicore async initialization that was dropped during public API restructuring in v4.0.0 (snowflakedb/snowflake-jdbc#2501)\n - Adjust level of logging during Driver initialization (snowflakedb/snowflake-jdbc#2504)\n - Add sanitization for nonProxyHosts RegEx patterns (snowflakedb/snowflake-jdbc#2506)\n - Fix bug with malformed file during S3 upload (snowflakedb/snowflake-jdbc#2502)\n - Added periodic closure of sockets closed by the remote end (snowflakedb/snowflake-jdbc#2481).\n - Add internal API usage telemetry tracker (snowflakedb/snowflake-jdbc#2509)\n - Change S3 Client's multipart threshold to 16MB (snowflakedb/snowflake-jdbc#2526)\n - Fixed fat jar with S3 iteration, the problem of not finding class `software.amazon.awssdk.transfer.s3.internal.ApplyUserAgentInterceptor` (snowflakedb/snowflake-jdbc#2519).\n - Removed Conscrypt from shading to prevent `failed to find class org/conscrypt/CryptoUpcalls` native error (snowflakedb/snowflake-jdbc#2519).\n - Add logging implementation to CLIENT_ENVIRONMENT telemetry (snowflakedb/snowflake-jdbc#2527)\n - Fix NPE when HOME directory cache is not available (snowflakedb/snowflake-jdbc#2534)\n - Bumped `commons-compress` dependency to latest (1.28.0) to address CVE-2024-25710 and CVE-2024-26308 (snowflakedb/snowflake-jdbc#2538)\n - Add SLF4J bridge from shaded dependencies to `SFLogger` (snowflakedb/snowflake-jdbc#2543)\n - Fixed proxy authentication when connecting to GCP (snowflakedb/snowflake-jdbc#2540)\n - Fixed bug where called-provided schema was ignored in getStreams() (snowflakedb/snowflake-jdbc#2546)\n - Fixed S3 error handling manifested with `NullPointerException` (snowflakedb/snowflake-jdbc#2550)\n\n- v4.0.1\n - Add /etc/os-release data to Minicore telemetry (snowflakedb/snowflake-jdbc#2470)\n - Fix incorrect encryption algorithm chosen when a file was put to S3 with client_encryption_key_size account parameter set to 256 (snowflakedb/snowflake-jdbc#2472) \n - Fixed fat jar with S3 iteration, the problem of not finding class `software.amazon.awssdk.transfer.s3.internal.ApplyUserAgentInterceptor` (snowflakedb/snowflake-jdbc#2474).\n - Removed Conscrypt from shading to prevent `failed to find class org/conscrypt/CryptoUpcalls` native error (snowflakedb/snowflake-jdbc#2474).\n - Update BouncyCastle dependencies to fix CVE-2025-8916 CVE-2025-8885 (snowflakedb/snowflake-jdbc#2479)\n - Fix external browser authentication after changing enum name.

They run part of the JDBC build jobs.\n- The integration test class names end with ``IT``. They run part of the ``verify`` maven goal along with the test category specified by the parameter ``testCategory`` having ``net.snowflake.client.category`` classes.\n- The manual test class names end with ``Manual``. They don't run in the CI but you can run them manually.\n\nAside from the general test criteria, the test case class names ending with ``LatestIT`` run only with the latest JDBC driver.\nThe main motivation behind is to skip those tests for the old JDBC driver. See ``./TestOnly`` directory for further information.\n\nSupport\n=============\n\nFeel free to file an issue or submit a PR here for general cases. For official support, contact Snowflake support at:\nhttps://community.snowflake.com/s/article/How-To-Submit-a-Support-Case-in-Snowflake-Lodge\n\nNotes\n----------\n\nThis driver support GCP regional endpoints starting from version 3.21.0. Please ensure that any workloads using through this driver below the version 3.21.0 do not require support for regional endpoints on GCP. If you have questions about this, please contact Snowflake Support.\n\nThe driver uses Rust library called sf_mini_core, you can find its source code

{@code\n * import net.snowflake.client.api.resultset.FieldMetadata;\n * import net.snowflake.client.api.resultset.SnowflakeType;\n *\n * // Get field metadata from a structured type column\n * FieldMetadata field = resultSetMetaData.getColumnFields(1).get(0);\n * SnowflakeType baseType = field.getBase();\n *\n * if (baseType == SnowflakeType.TEXT) {\n *     System.out.println(\"Field is a text type\");\n * } else if (baseType == SnowflakeType.INTEGER) {\n *     System.out.println(\"Field is an integer type\");\n * }\n * }
\n *\n * Additionally, this enum includes JDBC type code extensions for Snowflake-specific data types not\n * covered by {@link java.sql.Types}.\n *\n *

These constants can be used with {@link java.sql.PreparedStatement#setObject(int, Object,\n * int)} to specify the target SQL type when binding parameters to Snowflake-specific types. *\n *\n *

Example usage:\n *\n * 

{@code\n * PreparedStatement pstmt = connection.prepareStatement(\"INSERT INTO t VALUES (?)\");\n * pstmt.setObject(1, myTimestamp, SnowflakeType.EXTRA_TYPES_TIMESTAMP_NTZ);\n * }

\n 
\n    Copyright (C) 1991, 1999 Free Software Foundation, Inc.\n    51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA\n    Everyone is permitted to copy and distribute verbatim copies\n    of this license document, but changing it is not allowed.\n\n    [This is the first released version of the Lesser GPL.  It also counts\n     as the successor of the GNU Library Public License, version 2, hence\n     the version number 2.1.]\n
\n\n
\n

Preamble

\n\n

\n The licenses for most software are designed to take away your\n freedom to share and change it. By contrast, the GNU General Public\n Licenses are intended to guarantee your freedom to share and change\n free software--to make sure the software is free for all its users.\n

\n

\n This license, the Lesser General Public License, applies to some\n specially designated software packages--typically libraries--of the\n Free Software Foundation and other authors who decide to use it. You\n can use it too, but we suggest you first think carefully about whether\n this license or the ordinary General Public License is the better\n strategy to use in any particular case, based on the explanations below.\n

\n

\n When we speak of free software, we are referring to freedom of use,\n not price. Our General Public Licenses are designed to make sure that\n you have the freedom to distribute copies of free software (and charge\n for this service if you wish); that you receive source code or can get\n it if you want it; that you can change the software and use pieces of\n it in new free programs; and that you are informed that you can do\n these things.\n

\n

\n To protect your rights, we need to make restrictions that forbid\n distributors to deny you these rights or to ask you to surrender these\n rights. These restrictions translate to certain responsibilities for\n you if you distribute copies of the library or if you modify it.\n

\n

\n For example, if you distribute copies of the library, whether gratis\n or for a fee, you must give the recipients all the rights that we gave\n you. You must make sure that they, too, receive or can get the source\n code. If you link other code with the library, you must provide\n complete object files to the recipients, so that they can relink them\n with the library after making changes to the library and recompiling\n it. And you must show them these terms so they know their rights.\n

\n

\n We protect your rights with a two-step method: (1) we copyright the\n library, and (2) we offer you this license, which gives you legal\n permission to copy, distribute and/or modify the library.\n

\n

\n To protect each distributor, we want to make it very clear that\n there is no warranty for the free library. Also, if the library is\n modified by someone else and passed on, the recipients should know\n that what they have is not the original version, so that the original\n author's reputation will not be affected by problems that might be\n introduced by others.\n

\n

\n Finally, software patents pose a constant threat to the existence of\n any free program. We wish to make sure that a company cannot\n effectively restrict the users of a free program by obtaining a\n restrictive license from a patent holder. Therefore, we insist that\n any patent license obtained for a version of the library must be\n consistent with the full freedom of use specified in this license.\n

\n

\n Most GNU software, including some libraries, is covered by the\n ordinary GNU General Public License. This license, the GNU Lesser\n General Public License, applies to certain designated libraries, and\n is quite different from the ordinary General Public License. We use\n this license for certain libraries in order to permit linking those\n libraries into non-free programs.\n

\n

\n When a program is linked with a library, whether statically or using\n a shared library, the combination of the two is legally speaking a\n combined work, a derivative of the original library. The ordinary\n General Public License therefore permits such linking only if the\n entire combination fits its criteria of freedom. The Lesser General\n Public License permits more lax criteria for linking other code with\n the library.\n

\n

\n We call this license the \"Lesser\" General Public License because it\n does Less to protect the user's freedom than the ordinary General\n Public License. It also provides other free software developers Less\n of an advantage over competing non-free programs. These disadvantages\n are the reason we use the ordinary General Public License for many\n libraries. However, the Lesser license provides advantages in certain\n special circumstances.\n

\n

\n For example, on rare occasions, there may be a special need to\n encourage the widest possible use of a certain library, so that it becomes\n a de-facto standard. To achieve this, non-free programs must be\n allowed to use the library. A more frequent case is that a free\n library does the same job as widely used non-free libraries. In this\n case, there is little to gain by limiting the free library to free\n software only, so we use the Lesser General Public License.\n

\n

\n In other cases, permission to use a particular library in non-free\n programs enables a greater number of people to use a large body of\n free software. For example, permission to use the GNU C Library in\n non-free programs enables many more people to use the whole GNU\n operating system, as well as its variant, the GNU/Linux operating\n system.\n

\n

\n Although the Lesser General Public License is Less protective of the\n users' freedom, it does ensure that the user of a program that is\n linked with the Library has the freedom and the wherewithal to run\n that program using a modified version of the Library.\n

\n

\n The precise terms and conditions for copying, distribution and\n modification follow. Pay close attention to the difference between a\n \"work based on the library\" and a \"work that uses the library\". The\n former contains code derived from the library, whereas the latter must\n be combined with the library in order to run.\n

\n\n

TERMS AND CONDITIONS FOR COPYING,\n DISTRIBUTION AND MODIFICATION

\n\n\n

\n 0.\n This License Agreement applies to any software library or other\n program which contains a notice placed by the copyright holder or\n other authorized party saying it may be distributed under the terms of\n this Lesser General Public License (also called \"this License\").\n Each licensee is addressed as \"you\".\n

\n

\n A \"library\" means a collection of software functions and/or data\n prepared so as to be conveniently linked with application programs\n (which use some of those functions and data) to form executables.\n

\n

\n The \"Library\", below, refers to any such software library or work\n which has been distributed under these terms. A \"work based on the\n Library\" means either the Library or any derivative work under\n copyright law: that is to say, a work containing the Library or a\n portion of it, either verbatim or with modifications and/or translated\n straightforwardly into another language. (Hereinafter, translation is\n included without limitation in the term \"modification\".)\n

\n

\n \"Source code\" for a work means the preferred form of the work for\n making modifications to it. For a library, complete source code means\n all the source code for all modules it contains, plus any associated\n interface definition files, plus the scripts used to control compilation\n and installation of the library.\n

\n

\n Activities other than copying, distribution and modification are not\n covered by this License; they are outside its scope. The act of\n running a program using the Library is not restricted, and output from\n such a program is covered only if its contents constitute a work based\n on the Library (independent of the use of the Library in a tool for\n writing it). Whether that is true depends on what the Library does\n and what the program that uses the Library does.\n

\n

\n 1.\n You may copy and distribute verbatim copies of the Library's\n complete source code as you receive it, in any medium, provided that\n you conspicuously and appropriately publish on each copy an\n appropriate copyright notice and disclaimer of warranty; keep intact\n all the notices that refer to this License and to the absence of any\n warranty; and distribute a copy of this License along with the\n Library.\n

\n

\n You may charge a fee for the physical act of transferring a copy,\n and you may at your option offer warranty protection in exchange for a\n fee.\n

\n

\n 2.\n You may modify your copy or copies of the Library or any portion\n of it, thus forming a work based on the Library, and copy and\n distribute such modifications or work under the terms of Section 1\n above, provided that you also meet all of these conditions:\n

\n\n
    \n
  • a)\n The modified work must itself be a software library.
    • \n
  • b)\n You must cause the files modified to carry prominent notices\n stating that you changed the files and the date of any change.
    • \n\n
  • c)\n You must cause the whole of the work to be licensed at no\n charge to all third parties under the terms of this License.
    • \n\n
  • d)\n If a facility in the modified Library refers to a function or a\n table of data to be supplied by an application program that uses\n the facility, other than as an argument passed when the facility\n is invoked, then you must make a good faith effort to ensure that,\n in the event an application does not supply such function or\n table, the facility still operates, and performs whatever part of\n its purpose remains meaningful.\n

    \n (For example, a function in a library to compute square roots has\n a purpose that is entirely well-defined independent of the\n application. Therefore, Subsection 2d requires that any\n application-supplied function or table used by this function must\n be optional: if the application does not supply it, the square\n root function must still compute square roots.)

    • \n
\n\n

\n These requirements apply to the modified work as a whole. If identifiable\n sections of that work are not derived from the Library, and can be\n reasonably considered independent and separate works in themselves, then\n this License, and its terms, do not apply to those sections when you\n distribute them as separate works. But when you distribute the same\n sections as part of a whole which is a work based on the Library, the\n distribution of the whole must be on the terms of this License, whose\n permissions for other licensees extend to the entire whole, and thus to\n each and every part regardless of who wrote it.\n

\n

\n Thus, it is not the intent of this section to claim rights or contest your\n rights to work written entirely by you; rather, the intent is to exercise\n the right to control the distribution of derivative or collective works\n based on the Library.\n

\n

\n In addition, mere aggregation of another work not based on the Library with\n the Library (or with a work based on the Library) on a volume of a storage\n or distribution medium does not bring the other work under the scope of\n this License.\n

\n

\n 3.\n You may opt to apply the terms of the ordinary GNU General Public\n License instead of this License to a given copy of the Library. To do\n this, you must alter all the notices that refer to this License, so\n that they refer to the ordinary GNU General Public License, version 2,\n instead of to this License. (If a newer version than version 2 of the\n ordinary GNU General Public License has appeared, then you can specify\n that version instead if you wish.) Do not make any other change in\n these notices.\n

\n

\n Once this change is made in a given copy, it is irreversible for\n that copy, so the ordinary GNU General Public License applies to all\n subsequent copies and derivative works made from that copy.\n

\n

\n This option is useful when you wish to copy part of the code of\n the Library into a program that is not a library.\n

\n

\n 4.\n You may copy and distribute the Library (or a portion or\n derivative of it, under Section 2) in object code or executable form\n under the terms of Sections 1 and 2 above provided that you accompany\n it with the complete corresponding machine-readable source code, which\n must be distributed under the terms of Sections 1 and 2 above on a\n medium customarily used for software interchange.\n

\n

\n If distribution of object code is made by offering access to copy\n from a designated place, then offering equivalent access to copy the\n source code from the same place satisfies the requirement to\n distribute the source code, even though third parties are not\n compelled to copy the source along with the object code.\n

\n

\n 5.\n A program that contains no derivative of any portion of the\n Library, but is designed to work with the Library by being compiled or\n linked with it, is called a \"work that uses the Library\". Such a\n work, in isolation, is not a derivative work of the Library, and\n therefore falls outside the scope of this License.\n

\n

\n However, linking a \"work that uses the Library\" with the Library\n creates an executable that is a derivative of the Library (because it\n contains portions of the Library), rather than a \"work that uses the\n library\". The executable is therefore covered by this License.\n Section 6 states terms for distribution of such executables.\n

\n

\n When a \"work that uses the Library\" uses material from a header file\n that is part of the Library, the object code for the work may be a\n derivative work of the Library even though the source code is not.\n Whether this is true is especially significant if the work can be\n linked without the Library, or if the work is itself a library. The\n threshold for this to be true is not precisely defined by law.\n

\n

\n If such an object file uses only numerical parameters, data\n structure layouts and accessors, and small macros and small inline\n functions (ten lines or less in length), then the use of the object\n file is unrestricted, regardless of whether it is legally a derivative\n work. (Executables containing this object code plus portions of the\n Library will still fall under Section 6.)\n

\n

\n Otherwise, if the work is a derivative of the Library, you may\n distribute the object code for the work under the terms of Section 6.\n Any executables containing that work also fall under Section 6,\n whether or not they are linked directly with the Library itself.\n

\n

\n 6.\n As an exception to the Sections above, you may also combine or\n link a \"work that uses the Library\" with the Library to produce a\n work containing portions of the Library, and distribute that work\n under terms of your choice, provided that the terms permit\n modification of the work for the customer's own use and reverse\n engineering for debugging such modifications.\n

\n

\n You must give prominent notice with each copy of the work that the\n Library is used in it and that the Library and its use are covered by\n this License. You must supply a copy of this License. If the work\n during execution displays copyright notices, you must include the\n copyright notice for the Library among them, as well as a reference\n directing the user to the copy of this License. Also, you must do one\n of these things:\n

\n\n
    \n
  • a) Accompany the work with the complete\n corresponding machine-readable source code for the Library\n including whatever changes were used in the work (which must be\n distributed under Sections 1 and 2 above); and, if the work is an\n executable linked with the Library, with the complete\n machine-readable \"work that uses the Library\", as object code\n and/or source code, so that the user can modify the Library and\n then relink to produce a modified executable containing the\n modified Library. (It is understood that the user who changes the\n contents of definitions files in the Library will not necessarily\n be able to recompile the application to use the modified\n definitions.)
    • \n\n
  • b) Use a suitable shared library mechanism\n for linking with the Library. A suitable mechanism is one that\n (1) uses at run time a copy of the library already present on the\n user's computer system, rather than copying library functions into\n the executable, and (2) will operate properly with a modified\n version of the library, if the user installs one, as long as the\n modified version is interface-compatible with the version that the\n work was made with.
    • \n\n
  • c) Accompany the work with a written offer,\n valid for at least three years, to give the same user the\n materials specified in Subsection 6a, above, for a charge no more\n than the cost of performing this distribution.
    • \n\n
  • d) If distribution of the work is made by\n offering access to copy from a designated place, offer equivalent\n access to copy the above specified materials from the same\n place.
    • \n\n
  • e) Verify that the user has already received\n a copy of these materials or that you have already sent this user\n a copy.
    • \n
\n\n

\n For an executable, the required form of the \"work that uses the\n Library\" must include any data and utility programs needed for\n reproducing the executable from it. However, as a special exception,\n the materials to be distributed need not include anything that is\n normally distributed (in either source or binary form) with the major\n components (compiler, kernel, and so on) of the operating system on\n which the executable runs, unless that component itself accompanies\n the executable.\n

\n

\n It may happen that this requirement contradicts the license\n restrictions of other proprietary libraries that do not normally\n accompany the operating system. Such a contradiction means you cannot\n use both them and the Library together in an executable that you\n distribute.\n

\n

\n 7. You may place library facilities that are a work\n based on the Library side-by-side in a single library together with\n other library facilities not covered by this License, and distribute\n such a combined library, provided that the separate distribution of\n the work based on the Library and of the other library facilities is\n otherwise permitted, and provided that you do these two things:\n

\n\n
    \n
  • a) Accompany the combined library with a copy\n of the same work based on the Library, uncombined with any other\n library facilities. This must be distributed under the terms of\n the Sections above.
    • \n\n
  • b) Give prominent notice with the combined\n library of the fact that part of it is a work based on the\n Library, and explaining where to find the accompanying uncombined\n form of the same work.
    • \n
\n\n

\n 8. You may not copy, modify, sublicense, link with,\n or distribute the Library except as expressly provided under this\n License. Any attempt otherwise to copy, modify, sublicense, link\n with, or distribute the Library is void, and will automatically\n terminate your rights under this License. However, parties who have\n received copies, or rights, from you under this License will not have\n their licenses terminated so long as such parties remain in full\n compliance.\n

\n

\n 9.\n You are not required to accept this License, since you have not\n signed it. However, nothing else grants you permission to modify or\n distribute the Library or its derivative works. These actions are\n prohibited by law if you do not accept this License. Therefore, by\n modifying or distributing the Library (or any work based on the\n Library), you indicate your acceptance of this License to do so, and\n all its terms and conditions for copying, distributing or modifying\n the Library or works based on it.\n

\n

\n 10.\n Each time you redistribute the Library (or any work based on the\n Library), the recipient automatically receives a license from the\n original licensor to copy, distribute, link with or modify the Library\n subject to these terms and conditions. You may not impose any further\n restrictions on the recipients' exercise of the rights granted herein.\n You are not responsible for enforcing compliance by third parties with\n this License.\n

\n

\n 11.\n If, as a consequence of a court judgment or allegation of patent\n infringement or for any other reason (not limited to patent issues),\n conditions are imposed on you (whether by court order, agreement or\n otherwise) that contradict the conditions of this License, they do not\n excuse you from the conditions of this License. If you cannot\n distribute so as to satisfy simultaneously your obligations under this\n License and any other pertinent obligations, then as a consequence you\n may not distribute the Library at all. For example, if a patent\n license would not permit royalty-free redistribution of the Library by\n all those who receive copies directly or indirectly through you, then\n the only way you could satisfy both it and this License would be to\n refrain entirely from distribution of the Library.\n

\n

\n If any portion of this section is held invalid or unenforceable under any\n particular circumstance, the balance of the section is intended to apply,\n and the section as a whole is intended to apply in other circumstances.\n

\n

\n It is not the purpose of this section to induce you to infringe any\n patents or other property right claims or to contest validity of any\n such claims; this section has the sole purpose of protecting the\n integrity of the free software distribution system which is\n implemented by public license practices. Many people have made\n generous contributions to the wide range of software distributed\n through that system in reliance on consistent application of that\n system; it is up to the author/donor to decide if he or she is willing\n to distribute software through any other system and a licensee cannot\n impose that choice.\n

\n

\n This section is intended to make thoroughly clear what is believed to\n be a consequence of the rest of this License.\n

\n

\n 12.\n If the distribution and/or use of the Library is restricted in\n certain countries either by patents or by copyrighted interfaces, the\n original copyright holder who places the Library under this License may add\n an explicit geographical distribution limitation excluding those countries,\n so that distribution is permitted only in or among countries not thus\n excluded. In such case, this License incorporates the limitation as if\n written in the body of this License.\n

\n

\n 13.\n The Free Software Foundation may publish revised and/or new\n versions of the Lesser General Public License from time to time.\n Such new versions will be similar in spirit to the present version,\n but may differ in detail to address new problems or concerns.\n

\n

\n Each version is given a distinguishing version number. If the Library\n specifies a version number of this License which applies to it and\n \"any later version\", you have the option of following the terms and\n conditions either of that version or of any later version published by\n the Free Software Foundation. If the Library does not specify a\n license version number, you may choose any version ever published by\n the Free Software Foundation.\n

\n

\n 14.\n If you wish to incorporate parts of the Library into other free\n programs whose distribution conditions are incompatible with these,\n write to the author to ask for permission. For software which is\n copyrighted by the Free Software Foundation, write to the Free\n Software Foundation; we sometimes make exceptions for this. Our\n decision will be guided by the two goals of preserving the free status\n of all derivatives of our free software and of promoting the sharing\n and reuse of software generally.\n

\n

    Distribution Obligations.
    \n
    \n 3.1. Availability of Source Code.\n
    \n
    \n Any Covered Software that You distribute or otherwise make available\n in Executable form must also be made available in Source Code form\n and that Source Code form must be distributed only under the terms\n of this License. You must include a copy of this License with every\n copy of the Source Code form of the Covered Software You distribute\n or otherwise make available. You must inform recipients of any such\n Covered Software in Executable form as to how they can obtain such\n Covered Software in Source Code form in a reasonable manner on or\n through a medium customarily used for software exchange.\n
    \n
    \n 3.2. Modifications.\n
    \n
    \n The Modifications that You create or to which You contribute are\n governed by the terms of this License. You represent that You\n believe Your Modifications are Your original creation(s) and/or You\n have sufficient rights to grant the rights conveyed by this License.\n
    \n
    \n 3.3. Required Notices.\n
    \n
    \n You must include a notice in each of Your Modifications that\n identifies You as the Contributor of the Modification. You may not\n remove or alter any copyright, patent or trademark notices contained\n within the Covered Software, or any notices of licensing or any\n descriptive text giving attribution to any Contributor or the\n Initial Developer.\n
    \n
    \n 3.4. Application of Additional Terms.\n
    \n
    \n You may not offer or impose any terms on any Covered Software in\n Source Code form that alters or restricts the applicable version of\n this License or the recipients' rights hereunder. You may choose to\n offer, and to charge a fee for, warranty, support, indemnity or\n liability obligations to one or more recipients of Covered Software.\n However, you may do so only on Your own behalf, and not on behalf of\n the Initial Developer or any Contributor. You must make it\n absolutely clear that any such warranty, support, indemnity or\n liability obligation is offered by You alone, and You hereby agree\n to indemnify the Initial Developer and every Contributor for any\n liability incurred by the Initial Developer or such Contributor as a\n result of warranty, support, indemnity or liability terms You offer.\n
    \n
    \n 3.5. Distribution of Executable Versions.\n
    \n
    \n You may distribute the Executable form of the Covered Software under\n the terms of this License or under the terms of a license of Your\n choice, which may contain terms different from this License,\n provided that You are in compliance with the terms of this License\n and that the license for the Executable form does not attempt to\n limit or alter the recipient's rights in the Source Code form from\n the rights set forth in this License. If You distribute the Covered\n Software in Executable form under a different license, You must make\n it absolutely clear that any terms which differ from this License\n are offered by You alone, not by the Initial Developer or\n Contributor. You hereby agree to indemnify the Initial Developer and\n every Contributor for any liability incurred by the Initial\n Developer or such Contributor as a result of any such terms You offer.\n
    \n
    \n 3.6. Larger Works.\n
    \n
    \n You may create a Larger Work by combining Covered Software with\n other code not governed by the terms of this License and distribute\n the Larger Work as a single product. In such a case, You must make\n sure the requirements of this License are fulfilled for the Covered\n Software.\n

    Versions of the License.
    \n
    \n 4.1. New Versions\n
    \n
    \n Oracle is the initial license steward and may publish revised and/or\n new versions of this License from time to time. Each version will be\n given a distinguishing version number. Except as provided in Section\n 4.3, no one other than the license steward has the right to modify\n this License.\n
    \n
    \n 4.2. Effect of New Versions.\n
    \n
    \n You may always continue to use, distribute or otherwise make the\n Covered Software available under the terms of the version of the\n License under which You originally received the Covered Software. If\n the Initial Developer includes a notice in the Original Software\n prohibiting it from being distributed or otherwise made available\n under any subsequent version of the License, You must distribute and\n make the Covered Software available under the terms of the version\n of the License under which You originally received the Covered\n Software. Otherwise, You may also choose to use, distribute or\n otherwise make the Covered Software available under the terms of any\n subsequent version of the License published by the license steward.\n
    \n
    \n 4.3. Modified Versions.\n
    \n
    \n When You are an Initial Developer and You want to create a new\n license for Your Original Software, You may create and use a\n modified version of this License if You: (a) rename the license and\n remove any references to the name of the license steward (except to\n note that the license differs from this License); and (b) otherwise\n make it clear that the license contains terms which differ from this\n License.\n

    TERMINATION.
    \n
    \n 6.1. This License and the rights granted hereunder will terminate\n automatically if You fail to comply with terms herein and fail to\n cure such breach within 30 days of becoming aware of the breach.\n Provisions which, by their nature, must remain in effect beyond the\n termination of this License shall survive.\n
    \n
    \n 6.2. If You assert a patent infringement claim (excluding\n declaratory judgment actions) against Initial Developer or a\n Contributor (the Initial Developer or Contributor against whom You\n assert such claim is referred to as \"Participant\") alleging that the\n Participant Software (meaning the Contributor Version where the\n Participant is a Contributor or the Original Software where the\n Participant is the Initial Developer) directly or indirectly\n infringes any patent, then any and all rights granted directly or\n indirectly to You by such Participant, the Initial Developer (if the\n Initial Developer is not the Participant) and all Contributors under\n Sections 2.1 and/or 2.2 of this License shall, upon 60 days notice\n from Participant terminate prospectively and automatically at the\n expiration of such 60 day notice period, unless if within such 60\n day period You withdraw Your claim with respect to the Participant\n Software against such Participant either unilaterally or pursuant to\n a written agreement with Participant.\n
    \n
    \n 6.3. If You assert a patent infringement claim against Participant\n alleging that the Participant Software directly or indirectly\n infringes any patent where such claim is resolved (such as by\n license or settlement) prior to the initiation of patent\n infringement litigation, then the reasonable value of the licenses\n granted by such Participant under Sections 2.1 or 2.2 shall be taken\n into account in determining the amount or value of any payment or\n license.\n
    \n
    \n 6.4. In the event of termination under Sections 6.1 or 6.2 above,\n all end user licenses that have been validly granted by You or any\n distributor hereunder prior to termination (excluding licenses\n granted to You by any distributor) shall survive termination. \n

GNU GENERAL PUBLIC LICENSE

\n

\n Version 2, June 1991
\n https://www.gnu.org/licenses/old-licenses/gpl-2.0.html\n

\n\n 
\n      Copyright (C) 1989, 1991 Free Software Foundation, Inc.\n      51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA\n\n      Everyone is permitted to copy and distribute verbatim copies\n      of this license document, but changing it is not allowed.\n
\n\n

Preamble

\n\n

\n The licenses for most software are designed to take away your\n freedom to share and change it. By contrast, the GNU General Public\n License is intended to guarantee your freedom to share and change free\n software--to make sure the software is free for all its users. This\n General Public License applies to most of the Free Software\n Foundation's software and to any other program whose authors commit to\n using it. (Some other Free Software Foundation software is covered by\n the GNU Lesser General Public License instead.) You can apply it to\n your programs, too.\n

\n\n

\n When we speak of free software, we are referring to freedom, not\n price. Our General Public Licenses are designed to make sure that you\n have the freedom to distribute copies of free software (and charge for\n this service if you wish), that you receive source code or can get it\n if you want it, that you can change the software or use pieces of it\n in new free programs; and that you know you can do these things.\n

\n\n

\n To protect your rights, we need to make restrictions that forbid\n anyone to deny you these rights or to ask you to surrender the rights.\n These restrictions translate to certain responsibilities for you if you\n distribute copies of the software, or if you modify it.\n

\n\n

\n For example, if you distribute copies of such a program, whether\n gratis or for a fee, you must give the recipients all the rights that\n you have. You must make sure that they, too, receive or can get the\n source code. And you must show them these terms so they know their\n rights.\n

\n\n

\n We protect your rights with two steps: (1) copyright the software, and\n (2) offer you this license which gives you legal permission to copy,\n distribute and/or modify the software.\n

\n\n

\n Also, for each author's protection and ours, we want to make certain\n that everyone understands that there is no warranty for this free\n software. If the software is modified by someone else and passed on, we\n want its recipients to know that what they have is not the original, so\n that any problems introduced by others will not reflect on the original\n authors' reputations.\n

\n\n

\n Finally, any free program is threatened constantly by software\n patents. We wish to avoid the danger that redistributors of a free\n program will individually obtain patent licenses, in effect making the\n program proprietary. To prevent this, we have made it clear that any\n patent must be licensed for everyone's free use or not licensed at all.\n

\n\n

\n The precise terms and conditions for copying, distribution and\n modification follow.\n

\n\n\n

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

\n\n\n

\n 0.\n This License applies to any program or other work which contains\n a notice placed by the copyright holder saying it may be distributed\n under the terms of this General Public License. The \"Program\", below,\n refers to any such program or work, and a \"work based on the Program\"\n means either the Program or any derivative work under copyright law:\n that is to say, a work containing the Program or a portion of it,\n either verbatim or with modifications and/or translated into another\n language. (Hereinafter, translation is included without limitation in\n the term \"modification\".) Each licensee is addressed as \"you\".\n

\n\n

\n Activities other than copying, distribution and modification are not\n covered by this License; they are outside its scope. The act of\n running the Program is not restricted, and the output from the Program\n is covered only if its contents constitute a work based on the\n Program (independent of having been made by running the Program).\n Whether that is true depends on what the Program does.\n

\n\n

\n 1.\n You may copy and distribute verbatim copies of the Program's\n source code as you receive it, in any medium, provided that you\n conspicuously and appropriately publish on each copy an appropriate\n copyright notice and disclaimer of warranty; keep intact all the\n notices that refer to this License and to the absence of any warranty;\n and give any other recipients of the Program a copy of this License\n along with the Program.\n

\n\n

\n You may charge a fee for the physical act of transferring a copy, and\n you may at your option offer warranty protection in exchange for a fee.\n

\n\n

\n 2.\n You may modify your copy or copies of the Program or any portion\n of it, thus forming a work based on the Program, and copy and\n distribute such modifications or work under the terms of Section 1\n above, provided that you also meet all of these conditions:\n

\n\n
\n
\n
\n a)\n You must cause the modified files to carry prominent notices\n stating that you changed the files and the date of any change.\n
\n
\n
\n b)\n You must cause any work that you distribute or publish, that in\n whole or in part contains or is derived from the Program or any\n part thereof, to be licensed as a whole at no charge to all third\n parties under the terms of this License.\n
\n
\n
\n c)\n If the modified program normally reads commands interactively\n when run, you must cause it, when started running for such\n interactive use in the most ordinary way, to print or display an\n announcement including an appropriate copyright notice and a\n notice that there is no warranty (or else, saying that you provide\n a warranty) and that users may redistribute the program under\n these conditions, and telling the user how to view a copy of this\n License. (Exception: if the Program itself is interactive but\n does not normally print such an announcement, your work based on\n the Program is not required to print an announcement.)\n
\n
\n\n

\n These requirements apply to the modified work as a whole. If\n identifiable sections of that work are not derived from the Program,\n and can be reasonably considered independent and separate works in\n themselves, then this License, and its terms, do not apply to those\n sections when you distribute them as separate works. But when you\n distribute the same sections as part of a whole which is a work based\n on the Program, the distribution of the whole must be on the terms of\n this License, whose permissions for other licensees extend to the\n entire whole, and thus to each and every part regardless of who wrote it.\n

\n\n

\n Thus, it is not the intent of this section to claim rights or contest\n your rights to work written entirely by you; rather, the intent is to\n exercise the right to control the distribution of derivative or\n collective works based on the Program.\n

\n\n

\n In addition, mere aggregation of another work not based on the Program\n with the Program (or with a work based on the Program) on a volume of\n a storage or distribution medium does not bring the other work under\n the scope of this License.\n

\n\n

\n 3.\n You may copy and distribute the Program (or a work based on it,\n under Section 2) in object code or executable form under the terms of\n Sections 1 and 2 above provided that you also do one of the following:\n

\n\n \n \n\n
\n
\n
\n a)\n Accompany it with the complete corresponding machine-readable\n source code, which must be distributed under the terms of Sections\n 1 and 2 above on a medium customarily used for software interchange; or,\n
\n
\n
\n b)\n Accompany it with a written offer, valid for at least three\n years, to give any third party, for a charge no more than your\n cost of physically performing source distribution, a complete\n machine-readable copy of the corresponding source code, to be\n distributed under the terms of Sections 1 and 2 above on a medium\n customarily used for software interchange; or,\n
\n
\n
\n c)\n Accompany it with the information you received as to the offer\n to distribute corresponding source code. (This alternative is\n allowed only for noncommercial distribution and only if you\n received the program in object code or executable form with such\n an offer, in accord with Subsection b above.)\n
\n
\n\n

\n The source code for a work means the preferred form of the work for\n making modifications to it. For an executable work, complete source\n code means all the source code for all modules it contains, plus any\n associated interface definition files, plus the scripts used to\n control compilation and installation of the executable. However, as a\n special exception, the source code distributed need not include\n anything that is normally distributed (in either source or binary\n form) with the major components (compiler, kernel, and so on) of the\n operating system on which the executable runs, unless that component\n itself accompanies the executable.\n

\n\n

\n If distribution of executable or object code is made by offering\n access to copy from a designated place, then offering equivalent\n access to copy the source code from the same place counts as\n distribution of the source code, even though third parties are not\n compelled to copy the source along with the object code.\n

\n\n

\n 4.\n You may not copy, modify, sublicense, or distribute the Program\n except as expressly provided under this License. Any attempt\n otherwise to copy, modify, sublicense or distribute the Program is\n void, and will automatically terminate your rights under this License.\n However, parties who have received copies, or rights, from you under\n this License will not have their licenses terminated so long as such\n parties remain in full compliance.\n

\n\n

\n 5.\n You are not required to accept this License, since you have not\n signed it. However, nothing else grants you permission to modify or\n distribute the Program or its derivative works. These actions are\n prohibited by law if you do not accept this License. Therefore, by\n modifying or distributing the Program (or any work based on the\n Program), you indicate your acceptance of this License to do so, and\n all its terms and conditions for copying, distributing or modifying\n the Program or works based on it.\n

\n\n

\n 6.\n Each time you redistribute the Program (or any work based on the\n Program), the recipient automatically receives a license from the\n original licensor to copy, distribute or modify the Program subject to\n these terms and conditions. You may not impose any further\n restrictions on the recipients' exercise of the rights granted herein.\n You are not responsible for enforcing compliance by third parties to\n this License.\n

\n\n

\n 7.\n If, as a consequence of a court judgment or allegation of patent\n infringement or for any other reason (not limited to patent issues),\n conditions are imposed on you (whether by court order, agreement or\n otherwise) that contradict the conditions of this License, they do not\n excuse you from the conditions of this License. If you cannot\n distribute so as to satisfy simultaneously your obligations under this\n License and any other pertinent obligations, then as a consequence you\n may not distribute the Program at all. For example, if a patent\n license would not permit royalty-free redistribution of the Program by\n all those who receive copies directly or indirectly through you, then\n the only way you could satisfy both it and this License would be to\n refrain entirely from distribution of the Program.\n

\n\n

\n If any portion of this section is held invalid or unenforceable under\n any particular circumstance, the balance of the section is intended to\n apply and the section as a whole is intended to apply in other\n circumstances.\n

\n\n

\n It is not the purpose of this section to induce you to infringe any\n patents or other property right claims or to contest validity of any\n such claims; this section has the sole purpose of protecting the\n integrity of the free software distribution system, which is\n implemented by public license practices. Many people have made\n generous contributions to the wide range of software distributed\n through that system in reliance on consistent application of that\n system; it is up to the author/donor to decide if he or she is willing\n to distribute software through any other system and a licensee cannot\n impose that choice.\n

\n\n

\n This section is intended to make thoroughly clear what is believed to\n be a consequence of the rest of this License.\n

\n\n

\n 8.\n If the distribution and/or use of the Program is restricted in\n certain countries either by patents or by copyrighted interfaces, the\n original copyright holder who places the Program under this License\n may add an explicit geographical distribution limitation excluding\n those countries, so that distribution is permitted only in or among\n countries not thus excluded. In such case, this License incorporates\n the limitation as if written in the body of this License.\n

\n\n

\n 9.\n The Free Software Foundation may publish revised and/or new versions\n of the General Public License from time to time. Such new versions will\n be similar in spirit to the present version, but may differ in detail to\n address new problems or concerns.\n

\n\n

\n Each version is given a distinguishing version number. If the Program\n specifies a version number of this License which applies to it and \"any\n later version\", you have the option of following the terms and conditions\n either of that version or of any later version published by the Free\n Software Foundation. If the Program does not specify a version number of\n this License, you may choose any version ever published by the Free Software\n Foundation.\n

\n\n

\n 10.\n If you wish to incorporate parts of the Program into other free\n programs whose distribution conditions are different, write to the author\n to ask for permission. For software which is copyrighted by the Free\n Software Foundation, write to the Free Software Foundation; we sometimes\n make exceptions for this. Our decision will be guided by the two goals\n of preserving the free status of all derivatives of our free software and\n of promoting the sharing and reuse of software generally.\n

\n\n

NO WARRANTY

\n\n

\n 11.\n BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\n FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\n OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\n PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\n OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\n MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\n TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\n PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\n REPAIR OR CORRECTION.\n

\n\n

\n 12.\n IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\n WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\n REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\n INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\n OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\n TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\n YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\n PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\n POSSIBILITY OF SUCH DAMAGES.\n
