Aliaksey Kandratsenka bef6592746 refresh INSTALL 2023-07-31 15:10:56 -04:00
Aliaksey Kandratsenka e3de2e3242 remove obsolete references to code.google.com
I.e. somehow we managed to still point to (very) old gperftools
hosting location, so lets fix it at last.

Aliaksey Kandratsenka 46d3315ad7 amputate maybe_threads
This facility allowed us to build tcmalloc without linking in actual
-lpthread. Via weak symbols we checked at runtime if pthread functions
are available and if not, special single-threaded stubs were used
instead. Not always brining in pthread dependency helped performance
of some programs or libraries which depended at runtime on whether
threads are linked or not. Most notable of those are libstdc++ which
uses non-atomic refcounting on single threaded programs.

But such optional dependency on pthreads caused complications for
nearly no benefit. One trouble was reported in github issue #1110.

This days glibc/libstdc++ combo actually depends on
sys/single_threaded.h facility. So bringing pthread at runtime is
fine. Also modern glibc ships pthread symbols inside libc anyways and
libpthread is empty. I also found that for whatever reason on BSDs and
osx we already pulled in proper pthreads too.

So we loose nothing and we get issue #1110 fixed. And we simplify
everything.

Chris Cambly 2d70ea9ad2 initial batch of changes to enable AIX in 32-bit and 64-bit
- Some small automake changes. Add libc++ for AIX instead of libstdc++
- Add the interface changes for AIX:User-defined malloc replacement
- Add code to avoid use of pthreads library prior to its initialization
- Some small changes to the unittest case
- Update INSTALL for AIX

Raphael Moreira Zinsly 3f55d874be New configure flags to set the alignment and page size of tcmalloc
Added two new configure flags, --with-tcmalloc-pagesize and
--with-tcmalloc-alignment, in order to set the tcmalloc internal page
size and tcmalloc allocation alignment without the need of a compiler
directive and to make the choice of the page size independent of the
allocation alignment.

alkondratenko@gmail.com 05b100d9d4 issue-503: removed checked in configure and other auto* products
So that it's easier to contribute and review contributions.

People wishing to build gperftools from svn checkout should run
autogen.sh first which will create those files and then ./configure &&
make as usual

INSTALL file has updated instructions too.

chappedm@gmail.com bd3b3a7e9a issue-496: Fixes an issue where tcmalloc might deadlock in a thread calling fork
tcmalloc contained a bug where some internal locks were left in a undefined state
between fork, leaving the child process in a deadlock state. This patch fixes the
issue by introducing stricter locking between the parent nd child while forking.

chappedm@gmail.com 1243295cdc issue-475: Amend of r151 and r150
In revisions 151 and 150 an attempt was made to enable frame pointers by default for i386. However, in the process of doing so a number of files were inadvertently touched as a result of running autogen.sh. As a result, I have needed to roll back these revisions so that I can reattempt the change.

* google-perftools: version 0.90 release
	* (As the version-number jump hints, this is a major new release:
	  almost every piece of functionality was rewritten.  I can't do
	  justice to all the changes, but will concentrate on highlights.)
	*** USER-VISIBLE CHANGES:
	* Ability to "release" unused memory added to tcmalloc
	* Exposed more tweaking knobs via environment variables (see docs)
	* pprof tries harder to map addresses to functions
	* tcmalloc_minimal compiles and runs on FreeBSD 6.0 and Solaris 10
	*** INTERNAL CHANGES:
	* Much better 64-bit support
	* Better multiple-processor support (e.g. multicore contention tweaks)
	* Support for recent kernel ABI changes (e.g. new arg to mremap)
	* Addition of spinlocks to tcmalloc to reduce contention cost
	* Speed up tcmalloc by using __thread on systems that support TLS
	* Total redesign of heap-checker to improve liveness checking
	* More portable stack-frame analysis -- no more hard-coded constants!
	* Disentangled heap-profiler code and heap-checker code
	* Several new unittests to test, e.g., thread-contention costs
	* Lots of small (but important!) bug fixes: e.g., fixing GetPC on amd64
	*** KNOWN PROBLEMS:
	* CPU-profiling may crash on x86_64 (64-bit) systems.  See the README
	* Profiling/heap-checking may deadlock on x86_64 systems.  See README

* google-perftools: initial release:
	  The google-perftools package contains some utilities to improve
	  and analyze the performance of C++ programs.  This includes an
	  optimized thread-caching malloc() and cpu and heap profiling
	  utilities.
