Changelog

Source: NEWS.md

httpuv 1.6.17

  • Closed #426: Uses native symbol registration for calls into compiled code, resulting in performance gains from not having to perform a lookup on each call. (#427)

  • Fixed installation failures on macOS caused by the bundled libuv build trying to regenerate autotools files when only some tools (e.g., automake) are present. (#430)

  • Fixed a -single_module is obsolete linker warning on macOS with newer Apple toolchains that could surface as a significant warning in R CMD check. (#433)

  • Tests now gracefully skip when suggested packages (curl, websocket) are not installed, rather than failing the entire test suite. (#432)

httpuv 1.6.16

CRAN release: 2025-04-16

  • Added a mime type entry for .wasm files, which should be served as application/wasm. (#407)

  • Updated mime lookup table using mime R package 0.13. (#408)

  • Avoid some time-sensitive tests on CRAN. (#412)

httpuv 1.6.15

CRAN release: 2024-03-26

httpuv 1.6.14

CRAN release: 2024-01-26

  • Updated Makevars.ucrt for upcoming release of Rtools (thanks to Tomas Kalibera).

  • Fixed linking to zlib on macOS (thanks to @jeroen). (#387)

httpuv 1.6.13

CRAN release: 2023-12-06

  • Closed #388: Fix R CMD check warning re error() format strings (for r-devel). (#389)

httpuv 1.6.12

CRAN release: 2023-10-23

  • New runStaticServer() provides a convenient interface for serving a directory of static files. (#380)

httpuv 1.6.11

CRAN release: 2023-05-11

  • Fix race condition introduced in 1.6.10. (#363)

  • Hygiene and metadata improvements requested by CRAN. (#366, #369, #370)

httpuv 1.6.10

CRAN release: 2023-05-08

  • WebSocket connections now send Ping frames to the client every 20 seconds. This is only intended to serve as a keepalive for proxies that might be sitting in front of us; we don’t pay attention to whether a Pong response is received in a timely manner. (#359)

httpuv 1.6.9

CRAN release: 2023-02-14

  • Fixed #354: The incorrect method was called to clear a vector. (#355)

  • The src/Makevars file no longer sets CXX_STD=CXX11, and the DESCRIPTION file no longer lists SystemRequirements: C++11, because newer R versions always support C++11. (#356, #357)

httpuv 1.6.8

CRAN release: 2023-01-12

  • Fixed #351: A race condition could cause httpuv to crash when starting the background thread for I/O. (#352)

httpuv 1.6.7

CRAN release: 2022-12-14

  • Fixed rstudio/shiny#3741: The TZ environment variable could get unset in some cases. (#346)

  • Closed #302: Fixed potential thread-safety issues with timegm2 implementation. (#346)

httpuv 1.6.6

CRAN release: 2022-09-08

httpuv 1.6.5

CRAN release: 2022-01-04

  • Added support for R on Windows UCRT. (#324)

  • When using a system-wide copy of libuv, httpuv will now compile using the system-wide headers for libuv, instead of the local copy of the libuv headers. (#327)

httpuv 1.6.4

CRAN release: 2021-12-14

  • Added zlib to SystemRequirements in DESCRIPTION file. (#315)

  • Closed #280: Fix builds on Alpine Linux (and other versions which have automake >1.16.1). (#319)

httpuv 1.6.3

CRAN release: 2021-09-09

  • Increased required version of Rcpp to 1.0.7, to work around an incompatibility between Rcpp 1.0.6 and packages compiled with Rcpp 1.0.7.

httpuv 1.6.2

CRAN release: 2021-08-18

  • Fixed #282: startPipeServer() failed with “invalid argument” error after update to libuv 1.37.0. (#283)

  • Fixed #303: Don’t return Content-Length header when the HTTP status is “101 Switching Protocols”. (#305)

  • Added support for gzip-compressed HTTP responses. (#305)

httpuv 1.6.1

CRAN release: 2021-05-07

  • The timegm() function is a non-standard GNU extension, so it has been replaced with an internal timegm2() function. (#300)

httpuv 1.6.0

CRAN release: 2021-04-23

  • Remove BH dependency. httpuv now requires a compiler which supports C++11. (#297)

httpuv 1.5.5

CRAN release: 2021-01-13

  • Fix SHA1 calculation, and thus WebSocket server handshakes, on big-endian systems. (#284)

  • Fixed #195: Responses required headers to be a named list. Now it can also be NULL, an empty unnamed list, or it can be unset. (#289)

  • Allow responses to omit body (or set it as NULL) to avoid sending a body or setting the Content-Length header. This is intended for use with HTTP 204/304 responses. (#288)

httpuv 1.5.4

CRAN release: 2020-06-06

  • Fixed #275: Large HTTP request headers could get truncated if they spanned more than one TCP message. (#277)

  • Fixed build for Solaris. (#271)

  • Fixed a test that had incorrect logic. (#272)

httpuv 1.5.3.1

CRAN release: 2020-05-26

  • Updated libuv to version 1.37.0. (#266)

  • Fixed #204: On UBSAN builds of R, there were warnings about unaligned memory access. (#246)

  • Avoid creating a new Rook error stream object for each request. This should improve performance. (#245)

  • Resolved #247: httpuv no longer returns a HTTP 400 code for static files when the “Content-Length” header is 0. This Content-Length header is inserted by some proxies even for messages without payloads. (#248)

  • Resolved #253: Setting the FRAMEWORK environment variable would break compilation. This change removes any dependency on that variable. (#254)

httpuv 1.5.2

CRAN release: 2019-09-11

  • In the static file-serving code path, httpuv previously looked for a Connection: upgrade header; if it found this header, it would not try to serve a static file, and it would instead forward the HTTP request to the R code path. However, some proxies are configured to always set this header, even when the connection is not actually meant to be upgraded. Now, instead of looking for a Connection: upgrade header, httpuv looks for the presence of an Upgrade header (with any value), and should be more robust to incorrectly-configured proxies. (#215)

  • Fixed handling of messages without payloads: (#219)

  • Fixed #224: Static file serving on Windows did not work correctly if it was from a path that contained non-ASCII characters. (#227)

  • Resolved #194, #233: Added a quiet option to startServer, which suppresses startup error messages that are normally printed to console (and can’t be intercepted with capture.output()). (#234)

  • Added a new function randomPort(), which returns a random available port for listening on. (#234)

  • Added a new (unexported) function logLevel(), for controlling debugging information that will be printed to the console. Previously, httpuv occasionally printed messages like ERROR: [uv_write] broken pipe and ERROR: [uv_write] bad file descriptor by default. This happened when the server tried to write to a pipe that was already closed, but the situation was not harmful, and was already being handled correctly. Now these messages are printed only if the log level is set to INFO or DEBUG. (#223)

  • If an application’s $call() method is missing, it will now give a 404 response instead of a 500 response. (#237)

  • Disallowed backslash in static path, to prevent path traversal attacks. (#235)

  • Static file serving on Windows could fail if multiple requests accessed the same file simultaneously. (#239)

httpuv 1.5.1

CRAN release: 2019-04-05

  • Fixed issues for compilers that didn’t support C++11, notably on RHEL and Centos 6. (#210)

  • Fixed #208: In some cases, a race condition could cause the R process to exit when starting a new server. (#211)

  • Updated to libuv 1.27.0. This fixed fixed #213: Valgrind reported an error about a pointer pointing to uninitialized memory. (#214)

httpuv 1.5.0

CRAN release: 2019-03-15

  • Added support for serving static files from the background I/O thread. Files can now be served from the filesystem without involving the main R thread, which means that these operations won’t block or be blocked by code that runs in the main R thread. (#177)

  • Running httpuv applications are now represented by R6 objects of class WebServer and PipeServer. These objects have methods to query and update the application. (#177)

  • Converted existing reference classes (InputStream, NullInputStream, ErrorStream, AppWrapper, and WebSocket) to R6 classes. (#178)

  • Fixed #168: A SIGPIPE signal on the httpuv background thread could cause the process to quit. This can happen in some instances when the server is under heavy load. (#169)

  • Fixed #122: decodeURI() and decodeURIComponent() previously returned strings encoded with the system’s native encoding; they now return UTF-8 encoded strings. (#185, #192)

  • encodeURI() and encodeURIComponent(), now convert their inputs to UTF-8 before URL-encoding. (#192)

  • encodeURI(), encodeURIComponent(), decodeURI(), and decodeURIComponent() now handle NAs correctly. (#192)

  • service() now executes a single later callback, rather than all eligible callbacks. This gives callers more opportunities to perform their own housekeeping when multiple expensive callbacks queue up. (#176)

  • Fixed #173: The source code is now compiled with -DSTRICT_R_HEADERS, which eliminates the need to undefine the Realloc and Free macros.

  • Updated to libuv 1.23.1. (#174)

httpuv 1.4.5.1

CRAN release: 2018-12-18

  • Moved the C_VISIBILITY from PKG_CPPFLAGS to PKG_CFLAGS, and added CXX_VISIBILITY to PKG_CXXFLAGS, as requested by the CRAN maintainers.

httpuv 1.4.5

CRAN release: 2018-07-19

  • Fixed #161: An HTTP connection could get upgraded to a WebSocket too early, which sometimes resulted in closed connections. (#162)

httpuv 1.4.4.2

CRAN release: 2018-07-02

  • Changed compiler flags to work with gcc 8.10 on Windows, so that httpuv will build with the new versions of Rtools. (#160)

httpuv 1.4.4.1

CRAN release: 2018-06-18

  • Remove _GLIBCXX_ASSERTIONS compile flag, which caused CRAN checks to fail on gcc 7.

httpuv 1.4.4

  • Fixed #144: Before closing a handle, make sure that it is not already closing. (#145)

  • Exported ipFamily() function, which tests whether a string represents an IPv4 address, IPv6 address, or neither. (#142)

  • Templated C++ code with the format A<B<C>> has been changed to A<B<C> >. Allowing consecutive >> is a feature of C++11.

  • httpuv is now compiled with _GLIBCXX_ASSERTIONS, to help catch bugs. (#137)

  • The Rook req environment now includes an item req$HEADERS, which is a named character vector of request headers. (#143)

  • Fixed #101: If server creation fails, report reason why. (#146, #149)

  • Fixed #147: Santizer complained when starting app with startPipeServer after a failed app start. (#149)

  • Fixed #150, #151: On some platforms, httpuv would fail to install from a zip file because R’s unzip() function did not preserve the executable permission for src/libuv/configure. (#152)

  • Worked around an issue where Shiny apps couldn’t be viewed when launched from RStudio Server using Firefox. (#153)

httpuv 1.4.3

CRAN release: 2018-05-10

  • Fixed #127: Compilation failed on some platforms because NULL was used instead of an Rcpp::List. (#131)

  • Fixed #133: Assertion failures when running on Fedora 28. (#136)

  • Fixed #134: Sanitizer complains when starting app after a failed app start. (#138)

httpuv 1.4.2

CRAN release: 2018-05-03

  • Fixed #126: The Makevars.win file had a line with spaces instead of a tab. This caused problems when installing with the --clean flag.

  • Fixed #128: It was possible in rare cases for a segfault to occur when httpuv tried to close a connection twice. (#129)

httpuv 1.4.1

CRAN release: 2018-04-21

  • Addressed #123: service() now returns TRUE.

  • Fixed #124: On some CRAN build machines, the build was failing because of issues with the timestamps of input and output files for autotools in libuv/.

httpuv 1.4.0

CRAN release: 2018-04-19

  • Changed license from GPL 3 to GPL >= 2. (#109)

  • Added IPv6 support. (#115)

  • httpuv now does I/O on a background thread, which should allow for much better performance under load. (#106)

  • httpuv can now handle request callbacks asynchronously. (#80, (#97))

  • Fixed #72: httpuv previously did not close connections that had the Connection: close header, or were HTTP 1.0 (without Connection: keep-alive). (#99)

  • Fixed #71: In some cases, compiling httpuv would use system copies of library headers, but use local copies of libraries for linking. (#121)

  • Let Rcpp handle symbol registration. (#85)

  • Hide internal symbols from shared library on supported platforms. This reduces the risk of conflicts with other packages bundling libuv. (#85)

  • Fixed #86: encodeURI() gave incorrect output for non-ASCII characters. (#87)

  • Fixed #49: Some information was shared across separate requests.

  • Upgraded to libuv 1.15.0. (#91)

  • Upgraded to http-parser 2.7.1. (#93)

httpuv 1.3.5

CRAN release: 2017-07-04

  • Added function getRNGState.

httpuv 1.3.3

CRAN release: 2015-08-04

  • Error messages are now sent as UTF-8.

  • httpuv no longer adds a Content-Length header if one has already been provided. This is for Shiny issue #876.

httpuv 1.3.2

CRAN release: 2014-10-23

  • Add encodeURI, encodeURIComponent, decodeURI, and decodeURIComponent functions.

  • Compatibility with Rook middleware reference classes.

httpuv 1.3.1

  • Fix bug where websocket headers split over multiple packets would cause the payload to be parsed incorrectly.

httpuv 1.3.0

CRAN release: 2014-04-04

httpuv 1.2.3

CRAN release: 2014-02-19

  • Require Rcpp 0.11.0. The absence of this requirement made it too easy for Windows and Mac users with Rcpp 0.10 already installed to grab httpuv 1.2.2 binaries from CRAN, which are built against Rcpp 0.11, causing bad crashes due to Rcpp’s linkage changes.

httpuv 1.2.2

CRAN release: 2014-01-31

  • Export base64 encoding function rawToBase64.

  • Compatibility work for Rcpp 0.11.0.

httpuv 1.2.1

CRAN release: 2013-12-07

  • Solaris 10 compatibility fixes (courtesy of Dr. Brian Ripley).

httpuv 1.2.0

CRAN release: 2013-10-14

  • Fix IE10 websocket handshake failure.

  • Implement hixie-76 version of WebSocket protocol, for Safari 4 and QtWebKit.

httpuv 1.1.0

CRAN release: 2013-08-22

  • Fix issue #8: Bug in concurrent uploads.

  • Add interrupt() function for stopping the runloop.

  • Add REMOTE_ADDR and REMOTE_PORT to request environment.

  • Switch from git submodules to git subtree; much easier installation of development builds.

  • Upgrade to libuv v0.10.13.

  • Fix issue #13: Segfault on successful retry of server creation.

httpuv 1.0.6.3

CRAN release: 2013-06-01

  • Greatly improved stability under heavy load by ignoring SIGPIPE.

httpuv 1.0.6.2

  • Work properly with body=c(file="foo"). Previously this only worked if body was a list, not a character vector.

  • R CMD INSTALL will do git submodule update --init if necessary.

  • When onHeaders() callback returned a body, httpuv was not properly short-circuiting the request.

  • Ignore SIGPIPE permanently. This was still causing crashes under heavy real-world traffic.

httpuv 1.0.6.1

  • Make request available on websocket object.

httpuv 1.0.6

  • Support listening on pipes (Unix domain sockets have been tested, Windows named pipes have not been tested but may work).

  • Fix crash on CentOS 6.4 due to weird interaction with OpenSSL.

httpuv 1.0.5

CRAN release: 2013-03-11

  • Initial release.
