* Improve scalloc error messageFlorian Schmaus2019-08-121-2/+5
|
* improve execFlorian Fischer2019-08-121-2/+6
| | | | | fix usage print message if exec failed and exit with exit code 1
* use absolut path of benchmark binaryFlorian Fischer2019-08-121-1/+2
|
* add LD_LIBRARY_PATH to system installed allocatorsFlorian Fischer2019-08-121-4/+6
|
* add malloc_statsFlorian Fischer2019-08-121-0/+5
|
* use LD_LIBRARY_PATH for glibc instead of calling its loaderFlorian Fischer2019-08-126-25/+49
| | | | | | | | Calling the loader fails on non ELF executables. Exec, formerly run_cmd, now takes two options: -l LD_LIBRARY_PATH, -p LD_PRELOAD. -p sets LD_PRELOAD and -l LD_LIBRARY_PATH before executing the rest of argv. glibc no longer uses cmd_prefix in favor of LD_LIBRARY_PATH.
* add patch info to malloc_statsFlorian Fischer2019-08-115-49/+65

* Rework exec chainFlorian Fischer2019-08-113-19/+40
| | | | | | | | | | | | | | Originally the structure of the executed cmd was {measure cmd} {allocator cmd prefix} {cmd} with the parent environment except LD_PRELOAD was modified for the whole command chain. Unfortunatly perf causes segfaults with some allocators and measuring allocators cmd prefixes doesnt seem fair. So the new cmd chain looks like: {allocator cmd prefix} {measure cmd} run_cmd <LD_PRELOAD> {cmd} without touching the environment in python. run_cmd sets LD_PRELOAD to the value it received in argv[1] and executes argv[2] with the rest of argv. This does also measure code not part of the actual benchmark but in a equal manner and not only for some allocators.
* fix and adjust to mysql installations on Ubuntu 18.04Florian Fischer2019-08-111-7/+8

* use new location of bumpptrFlorian Fischer2019-08-111-1/+1
|
* except OSError: /usr/sbin/mysqld: cannot dynamically load executableFlorian Fischer2019-08-111-1/+5
|
* check if vm.overcommit_memory is set before building scallocFlorian Fischer2019-08-111-0/+8
| | | | | | | Scalloc checks if it is allowed to overcommit memory at runtime and aborts. Calling abort() does not set an exit code and therefore does not trigger allocbenchs failure handling. To prevent crashing at runtime we now fail early.
* make bump pointer allocator available through src.allocators.bumpptrFlorian Fischer2019-08-113-3/+5
|
* improve bumpptr_allocFlorian Fischer2019-08-112-7/+22
| | | | | Return always 16 Byte aligned blocks and mmap the whole available memory reported by free -t per thread.
* don't copy benchmark.allocators againFlorian Fischer2019-08-101-6/+0
|
* be more carefull with default entries in Benchmark.resultsFlorian Fischer2019-08-101-10/+18
|
* print malloc_stats to stdoutFlorian Fischer2019-08-101-1/+4
|
* fix Allocator.build() if sources are NoneFlorian Fischer2019-08-021-6/+6
|
* add facts to dataref exportFlorian Fischer2019-07-316-30/+54
|
* use libtbbmalloc_proxy which overwrites mallocFlorian Fischer2019-07-171-1/+1
|
* fix tbbmalloc definitionFlorian Fischer2019-07-031-1/+1
|
* add barrier to larson benchmarkFlorian Fischer2019-07-011-0/+10
| | | | | | The barrier prevents worker thread from doing work before the main thread starts the timing. This behaviour was mentioned in the paper: Mostly Lock-Free Malloc by Dave Dice, Alex Garthwaite
* add default colors to included allocatorsFlorian Fischer2019-07-0110-14/+19
|
* add mimalloc definitionFlorian Fischer2019-06-272-1/+27

* fix realloc micro benchmark for allocators returning null for realloc(ptr, 0)Florian Fischer2019-06-271-1/+1
|
* add tbbmalloc definitionFlorian Fischer2019-06-242-1/+26
|
* fix all allocators collectionFlorian Fischer2019-06-241-10/+3
|
* add mesh and lockless_allocator definitionsFlorian Fischer2019-06-244-2/+50
|
* rework allocator definitions #2Florian Fischer2019-06-2413-141/+135
| | | | | | | | bench.py no evals only if argument to -a is file path. Otherwise it will check if "arg".py is found in src/allocators/ then it imports it. Collection definitions must export a iterable member called allocators. Allocator definitions must export a member named "arg".

* fix cmd for non server benchmarksFlorian Fischer2019-05-151-1/+1
|
* introduce server concept to BenchmarkFlorian Fischer2019-05-153-136/+129
| | | | | | | | | | | | A benchmark object can specify a list of cmds to execute as "servers" in the member attribute server_cmds. Servers are started and terminated through Popen objects. This requires the server cmds to not daemonize so the server can be terminated through the Popen object. For each started server cmd a shutdown function is registered with atexit to terminate all servers even if a exception occurs. Use the new server concept in httpd and mysql benchmarks
* add function to prefix cmd with abspath using whereisFlorian Fischer2019-05-151-0/+18
|
* remove unused variableFlorian Fischer2019-05-151-1/+0
|
* add php to httpd benchmarkFlorian Fischer2019-05-158-75/+2666
| | | | | | | | | restructure httpd and php-fpm setup OBJDIR/etc holds configs OBJDIR/run holds pid files OBJDIR/log holds all log files don't daemonize nginx
