96a59c3bb5 Fix recursive malloc during bootstrap on QNX 
pthread_key_create on QNX triggers recursive allocation during tsd
bootstrapping. Using tsd_init_check_recursion to detect that.

Before pthread_key_create, the address of tsd_boot_wrapper is returned
from tsd_get_wrapper instead of using TLS to store the pointer.
tsd_set_wrapper becomes a no-op. After that, the address of
tsd_boot_wrapper is written to TLS and bootstrap continues as before.

a559caf74a hpdata: Strengthen assertions. 
Now that we have flat bitmap bit counting functions, we can easily assert that
nfree is always correct.  While we're tightening up this code, enforce
consistency on API boundaries as well.

f7cf23aa4d psset: Relegate alloc/dalloc to test code. 
This is no longer part of the "core" functionality; we only need the stub
implementations as an end-to-end test of hpdata + psset interactions when
metadata is being modified.  Treat them accordingly.

ca30b5db2b Introduce hpdata_t. 
Using an edata_t both for hugepages and the allocations within those hugepages
was convenient at first, but has outlived its usefulness.  Representing
hugepages explicitly, with their own data structure, will make future
development easier.

bf72188f80 Allow opt.tcache_max to accept small size classes. 
Previously all the small size classes were cached.  However this has downsides
-- particularly when page size is greater than 4K (e.g. iOS), which will result
in much higher SMALL_MAXCLASS.

This change allows tcache_max to be set to lower values, to better control
resources taken by tcache.

d16849c91d psset: Do first-fit based on slab age. 
This functions more like the serial number strategy of the ecache and

5e41ff9b74 Add a hard limit on tcache max size class. 
For locality reasons, tcache bins are integrated in TSD.  Allowing all size
classes to be cached has little benefit, but takes up much thread local storage.
In addition, it complicates the layout which we try hard to optimize.

9e6aa77ab9 PRNG: Remove atomic functionality. 
These had no uses and complicated the API.  As a rule we now expect to only use

018b162d67 Add psset: a set of pageslabs. 
This introduces a new sort of edata_t; a pageslab, and a set to manage them.
This is part of a series of a commits to implement a hugepage allocator; the
pageset will be per-arena, and track small page allocations requests within a
larger extent allocated from a centralized hugepage allocator.

7ad2f78663 Avoid a -Wundef warning on LG_SLAB_MAXREGS. 2020-09-17 10:05:40 -07:00
Hao Liu
1541ffc765 configure: add --with-lg-slab-maxregs configure option. 
Specify the maximum number of regions in a slab, which is
(<lg-page> - <lg-tiny-min>) by default. This increases the limit of slab sizes
specified by "slab_sizes" in malloc_conf. This should never be less than
the default value. The max value of this option is related to LG_BITMAP_MAXBITS
(see more in bitmap.h).

For example, on a 4k page size system, if we:
  1) configure jemalloc with with --with-lg-slab-maxregs=12.
  2) export MALLOC_CONF="slab_sizes:9-16:4"
The slab size of 16 bytes is set to 4 pages. Previously, the default
lg-slab-maxregs is 9 (i.e. 12 - 3). The max slab size of 16 bytes is 2 pages
(i.e. (1<<9) * 16 bytes). By increasing the value from 9 to 12, the max slab
size can be set by MALLOC_CONF is 16 pages (i.e. (1<<12) * 16 bytes).

9e18ae639f Config: safety checks don't imply size checks. 
The commit introducing size checks accidentally enabled them whenever any safety
checks were on.  This ends up causing the regression that splitting up the

eaed1e39be Add sized-delete size-checking functionality. 
The existing checks are good at finding such issues (on tcache flush), but not
so good at pinpointing them.  Debug mode can find them, but sometimes debug mode
slows down a program so much that hard-to-hit bugs can take a long time to
crash.

This commit adds functionality to keep programs mostly on their fast paths,
while also checking every sized delete argument they get.

60993697d8 Prof: Add prof_unbias. 
This gives more accurate attribution of bytes and counts to stack traces,
without introducing backwards incompatibilities in heap-profile parsing tools.
We track the ideal reported (to the end user) number of bytes more carefully
inside core jemalloc.  When dumping heap profiles, insteading of outputting our
counts directly, we output counts that will cause parsing tools to give a result
close to the value we want.

We retain the old version as an opt setting, to let users who are tracking
values on a per-component basis to keep their metrics stable until they decide
to switch.
