Changelog for process
package
- Fix build with Javascript backend (#327)
- Fix detection of
posix_spawn_file_actions_addchdir[_np]
(#303)
- Fix command-line escaping logic on Windows when the command file ends with a space or a dot. This is a follow-up for HSEC-2024-0003.
- Migitate another manifestation of the BatBadBut vulnerability via
unescaped
%
expansions. This is another follow-up for HSEC-2024-0003. (#313)
- Allow NUL to appear in arguments under POSIX. See #320. Thanks to @mmhat.
-
No longer attach finalizers to
Handle
s created by theSystem.Process.CommunicationHandle
API. Instead, all file descriptors are manually closed by the API.This fixes a bug in which a file descriptor could be closed multiple times.
- Introduce
System.Process.CommunicationHandle
, allowing for platform-independent inter-process communication usingHandle
s. - Expose
withForkWait
andignoreSigPipe
fromSystem.Process.Internals
. - Define new internal functions
rawFdToHandle
and (Windows only)rawHANDLEToHandle
, exported fromSystem.Process.Common
.
- Adjust command-line escaping logic on Windows to ensure that occurrences of
characters with special significance to the Windows batch interpreter are
properly escaped in arguments passed to
.bat
and.cmd
processes. This addresses HSEC-2024-0003. - Fix double-closing of stdin/stdout/stderr fds with POSIX
fork/exec
backend. #306 - Add support for
posix_spawn_file_actions_addchdir_np
- Fix deadlock when waiting for process completion and process jobs #273
- Support
delegate_ctlc
on Windows. #278 - Drop support for
vfork
#261 - Javascript backend support
- Fix potential segmentation fault on macOS #295
- Improved documentation for the
OpenExtHandle
constructor.
- Correct permissions on createPipe on Windows 234
- Ensure that both ends of pipes on Windows are created in the same mode 234
- Fixed an issue with WINIO where giving an application an inherited pipe can cause it to misbehave 245
- Set the encoding on WINIO created pipes to the local encoding as with MIO 248
- cbits/fork-exec: Don't dup2 identical fds #250
- posix: Ensure that
errno
is set afterposix_spawnp
fails #228 - Fix
waitForProcess
not closing process handles withdelegate_ctlc
#231 - Don't use
posix_spawn
on platforms where it does not reportENOENT
in caes where the requested executable does not exist #224 - Ensure that
find_executable
correctly-locates executables when a change in working directory is requested #219 - Fix capitalization error allowing
execvpe
to be used when available.
posix_spawn
: Don't attempt todup2
identical fds #214
- Patches for the previous release
- Refactoring of POSIX process logic #208
- Add function
getCurrentPid
to get the currently executing process' ID #205
- Windows: Add support for new I/O manager in GHC 8.12#177

request #176
- Fix another process wait bug on Windows.
- Fix a few warnings on Windows.
- Fix several bugs on Windows where use of process jobs would result in the process being prematurely terminated. See #168.
- Fix a race condition on Windows that happens when you use process jobs and one of the child processes terminates but doesn't release its resources immediately. Control returns to the caller too soon in this scenario. See #159
- Fix a potential privilege escalation issue (or, more precisely, privileges
not being dropped when this was the user's intent) where the groups of the
spawning process's user would be incorrectly retained due to a missing call to
initgroups
[#149]. - Bug fix: Prevent stripping undecodable bytes from environment variables when in a non-unicode locale. #152

runInteractiveProcess_lock
inSystem.Process.Internals
