Carl Shapiro	0d7a26e9b6	Remove an incorrect use of the address operator ... The address of the local variable created_threads is a different location than the data it points to. Incorrectly treating these values as being the same can cause out-of-bounds writes to the stack. Resolves #59	2025-12-23 21:59:04 -08:00
Carl Shapiro	7f043becad	Use the BRE construct \{1,\} for one or more consecutive matches ... This removes duplication introduced by my earlier commit that eliminating the use of the non-standard "\+" from BREs in the configure script.	2025-12-23 19:58:35 -08:00

Carl Shapiro	bfc20f2804	Inline the value of an always false boolean local variable ... Next to its use, which is always as an argument, we include the name of the parameter in a constant. This completes a partially implemented cleanup suggested in an earlier commit.	2025-10-07 14:55:36 -07:00
Slobodan Predolac	0669f70b67	[EASY] Spelling in the comments	2025-10-07 14:52:13 -07:00

guangli-dai	f29cfa8251	Remove Travis Windows CI for now since it has infra failures.	2025-09-17 17:29:38 -07:00
Slobodan Predolac	b7bedaf7a0	[sdt] Add some tracepoints to sec and hpa modules	2025-09-16 16:27:04 -07:00
Carl Shapiro	d74be2ea7c	Improve the portability of grep patterns in configure.ac ... The configure.ac script uses backslash plus in its grep patterns to match one or more occurrences. This is a GNU grep extension to the Basic Regular Expressions syntax that fails on systems with a more traditional grep. This changes fixes grep patterns that use backslash plus to use a star instead.	2025-09-16 14:35:51 -07:00
guangli-dai	5d18e0b340	Add a page-allocator microbenchmark.	2025-09-16 10:15:04 -04:00
guangli-dai	983773b118	Adding trace analysis in preparation for page allocator microbenchmark.	2025-09-16 10:15:04 -04:00
Carl Shapiro	c0889acb6c	Replace an instance of indentation with spaces with tabs	2025-09-12 10:31:54 -07:00
Aurélien Brooke	28fb5fabe7	Add missing thread_event_registry.c to Visual Studio projects ... This file was added by b2a35a905f.	2025-09-08 11:52:34 -07:00
lexprfuncall	cdc3b65300	Update config.guess and config.sub to the latest versions ... These files need to be refreshed periodically to support new platform types. The following command was used to retrieve the updates curl -L -O https://git.savannah.gnu.org/cgit/config.git/plain/config.guess curl -L -O https://git.savannah.gnu.org/cgit/config.git/plain/config.sub	2025-08-29 16:25:02 -07:00
Carl Shapiro	218c989047	Always use pthread_equal to compare thread IDs ... This change replaces direct comparisons of Pthread thread IDs with calls to pthread_equal. Directly comparing thread IDs is neither portable nor reliable since a thread ID is defined as an opaque type that can be implemented using a structure.	2025-08-28 14:45:51 -07:00
Slobodan Predolac	d4cde60066	Remove pidfd_open call handling and rely on PIDFD_SELF	2025-08-27 12:44:45 -04:00
lexprfuncall	7dcdafea00	Change the default page size to 64KiB on Aarch64 Linux ... This updates the configuration script to set the default page size to 64KiB on Aarch64 Linux. This is motivated by compatibility as a build configured for a 64KiB page will work on kernels that use the smaller 4KiB or 16KiB pages, whereas the reverse is not true. To make the configured page size setting more visible, the script now displays the page size when printing the configuration results. Users that want to override the page size in to choose a smaller value can still do so with the --with-lg-pagesize configuration option.	2025-08-26 18:10:05 -07:00
Slobodan Predolac	88b29da00a	[EASY][BUGFIX] Spelling and format	2025-08-23 21:47:21 -07:00
lexprfuncall	f890bbed4a	Define malloc_{write,read}_fd as non-inline global functions ... The static inline definition made more sense when these functions just dispatched to a syscall wrapper. Since they acquired a retry loop, a non-inline definition makes more sense.	2025-08-23 11:42:23 -04:00
lexprfuncall	6ced4b5afb	Handle interruptions and retries of read(2) and write(2)	2025-08-23 11:42:23 -04:00
lexprfuncall	5f06b14d1c	Remove an orphaned comment ... This was left behind when definitions of malloc_open and malloc_close were abstracted from code that had followed.	2025-08-23 11:42:23 -04:00
Shirui Cheng	e2da7477f8	Revert PR #2608: Manually revert commits 70c94d..f9c0b5	2025-08-22 21:55:24 -07:00
lexprfuncall	9186700eb3	Fix the compilation check for process madvise ... An include of unistd.h is needed to make the declaration of the syscall function visible to the compiler. The include of sys/mman.h is not used at all.	2025-08-21 22:43:02 -07:00
Slobodan Predolac	4f126b47b3	Save and restore errno when calling process_madvise	2025-08-21 16:22:06 -07:00
lexprfuncall	acd85e5359	Remove an unused function and global variable ... When the dehugify functionality was retired in an previous commit, a dehugify-related function and global variable in a test was accidentally left in-place causing builds that add -Werror to CFLAGS to fail.	2025-08-21 08:59:37 -07:00
Slobodan Predolac	f9fae9f1f8	Experimental configuration option for fast path prefetch from cache_bin	2025-08-15 16:06:08 -07:00
lexprfuncall	c45b6223e5	Use relaxed atomics to access the process madvise pid fd ... Relaxed atomics already provide sequentially consistent access to single location data structures.	2025-08-13 18:33:27 -07:00
lexprfuncall	16c5abd1cd	Do not dehugify when purging ... Giving the advice MADV_DONTNEED to a range of virtual memory backed by a transparent huge page already causes that range of virtual memory to become backed by regular pages.	2025-08-13 18:31:50 -07:00
lexprfuncall	0d071a086b	Fix several spelling errors in comments	2025-08-08 14:12:12 -07:00
