606ae49fa3 Integrate raw heap profile support into jeprof. 2015-11-09 14:59:14 -08:00
Jason Evans
7041720ac2 Rename pprof to jeprof.
This rename avoids installation collisions with the upstream gperftools.
Additionally, jemalloc's per thread heap profile functionality
introduced an incompatible file format, so it's now worthwhile to
clearly distinguish jemalloc's version of this script from the upstream
version.

This resolves #229.

b4acf7300a [pprof] Produce global profile unless thread-local profile requested
Currently pprof will print output for all threads if a single thread is not
specified, but this doesn't play well with many output formats (e.g., any of
the dot-based formats).  Instead, default to printing just the overall profile
when no specific thread is requested.

This resolves #157.

d95e704fea Support threaded heap profiles in pprof
- Add a --thread N option to select profile for thread N (otherwise, all
      threads will be printed)
    - The $profile map now has a {threads} element that is a map from thread id to
      a profile that has the same format as the {profile} element
    - Refactor ReadHeapProfile into smaller components and use them to implement
      ReadThreadedHeapProfile

6f001059aa Simplify backtracing.
Simplify backtracing to not ignore any frames, and compensate for this
in pprof in order to increase flexibility with respect to function-based
refactoring even in the presence of non-deterministic inlining.  Modify
pprof to blacklist all jemalloc allocation entry points including
non-standard ones like mallocx(), and ignore all allocator-internal
frames.  Prior to this change, pprof excluded the specifically
blacklisted functions from backtraces, but it left allocator-internal
frames intact.

4bbf8181f3 Consistently use debug lib(s) if present
Fixes a situation where nm uses the debug lib but
addr2line does not, which completely messes up the symbol
lookup.

7cdea3973c Few configure.ac adjustments
- Use the extensions autoconf finds for object and executable files.
- Remove the sorev variable, and replace SOREV definition with sorev's.
- Default to je_ prefix on win32.

a4936ce4d6 Fix jemalloc.sh code generation.
Fix jemalloc.sh code generation by adding @sorev@ and using it instead
of @SOREV@ (which contains Makefile-specific variables).

85221d5d75 Make versioned shared library suffix configurable
This allows for different patterns for file names:
- lib.so.version for e.g. Linux
- lib.version.dylib for OSX (which is much more common than
lib.dylib.version)
- lib.dll for Windows (no version at all).

f576c63f1e Refactor SO and REV make variables.
Refactor the SO and REV such that they are set via autoconf variables,
@so@ and @rev@.  These variables are both needed by the jemalloc.sh
script, so this unifies their definitions.
