2017-07-06dialyzer: Do not use deprecated functions in string(3)Hans Bolinder
2017-06-13dialyzer: Do not use two records for PLTsHans Bolinder
Instead of two records, #plt{} with dict:s and #mini_plt{} with ETS tables, one record is used for representing PLT:s in RAM. The #mini_plt{} is the one now used throughout analyses, but it is called #plt{}. When writing the PLT to file, another record is used, #file_plt{} (as before). When creating #file_plt{}, the #plt{} is deleted (it cannot be used for further analyses).
2017-06-09dialyzer: Improve handling of UnicodeHans Bolinder
2017-02-03dialyzer: Write PLT in subprocessHans Bolinder
At common case, which will otherwise leave a big heap.
2017-02-03dialyzer: Use less memory for the PLT when analyzingHans Bolinder
The two tables for (record) types and exported types are no longer kept in memory (by the PLT) when analyzing, which reduces memory consumption. A first step towards removing (or replacing) the #plt{} record.

2017-01-11dialyzer: Do not send full PLTs as messagesHans Bolinder
The mini PLT is extended to hold all data of the full PLT, and the full PLT is restored when needed (for storing the PLT on file).

2016-01-11Remove dead code related to missing behaviour infoStavros Aronis
Dialyzer used to report unknown behaviours in the same way as unknown functions and types. This functionality has been removed in d101155, but some code remained.
2015-10-09Update DialyzerHans Bolinder
Record field types have been modified due to commit 8ce35b2: "Take out automatic insertion of 'undefined' from typed record fields".
2015-08-31erts,hipe,dialyzer: Fix hipe checkum of target runtime systemSverker Eriksson
Main problem: A faulty HIPE_LITERAL_CRC was not detected by the loader. Strangeness #1: Dialyzer should ask the hipe compiler about the target checksum, not an internal bif. Strangeness #2: The HIPE_SYSTEM_CRC checksum was based on the HIPE_LITERALS_CRC checksum. Solution: New HIPE_ERTS_CHECKSUM which is an bxor of the two (now independent) HIPE_LITERALS_CRC and HIPE_SYSTEM_CRC. HIPE_LITERALS_CRC represents values that are assumed to stay constant for different VM configurations of the same arch, and are therefor hard coded into the hipe compiler. HIPE_SYSTEM_CRC represents values that may differ between VM variants. By default the hipe compiler asks the running VM for this checksum, in order to create beam files for the same running VM. The hipe compiler can be configured (with "make XCOMP=yes ...") to create beam files for another VM variant, in which case HIPE_SYSTEM_CRC is also hard coded. ToDo: Treat all erts properties the same. Either ask the running VM or hard coded into hipe (if XCOMP=yes). This will simplify and reduce the risk of dangerous mismatches. One concern might be the added overhead from more frequent calls to hipe_bifs:get_rts_param.

2015-05-28Dialyzer to cache results of HiPE compilationMagnus Henoch
Cache the results of native compilation in $XDG_CACHE_HOME/dialyzer_hipe_cache. This can reduce the startup time significantly. If XDG_CACHE_HOME is unset, it defaults to $HOME/.cache. See the XDG Base Directory spec for more details: http://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html Under that directory, create a subdirectory called ARCH-VERSION-CHECKSUM, where ARCH is the HiPE architecture, VERSION is the HiPE version number, and CHECKSUM is the return value of hipe_bifs:system_crc/0. Caching can be disabled by specifying --no_native_cache on the command line.
2015-04-27dialyzer: Add new option 'unknown'Hans Bolinder
Replace the undocumented option 'no_unknown' with the documented option 'unknown'.

Thanks to James Fish for the bug report, and to Stavros Aronis for fixing the bug.
2015-01-14dialyzer: Introduce module local suppression of warningsHans Bolinder
The -dialyzer() attribute can be used for suppressing warnings in a module by specifying functions or warning options. It can also be used for requesting warnings in a module.

2014-03-20Introduce a new warning option, 'no_unknown'Hans Bolinder
Not (yet) documented.
2014-03-20Return warnings for unknown types and functions in Erlang ModeHans Bolinder
The warnings about unknown types and functions are now returned when calling Dialyzer from Erlang, in particular from an escript. When calling Dialyzer from the command line the warnings about unknown types and functions are output last as before; and when using the GUI the warnings are displayed in a pop-up window, as before.
2014-03-17dialyzer: Do not native compile modules with Maps codeBjörn-Egil Dahlberg
hipe:c/1 ignores '-compile(no_native).'
2014-02-23Deprecate pre-defined built-in typesHans Bolinder
The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(), set(), and tid() have been deprecated. They will be removed in OTP 18.0. Instead the types array:array(), dict:dict(), digraph:graph(), gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid() can be used. (Note: it has always been necessary to use ets:tid().) It is allowed in OTP 17.0 to locally re-define the types array(), dict(), and so on. New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2, queue:queue/1, and sets:set/1 have been added.

2014-01-21[dialyzer] Re-work the handling of opaque typesHans Bolinder
It is now OK to inspect and modify the internals of opaque types within the scope of the module. The contracts are used for decorating types with opaqueness when it is harmless to do so. The opaqueness is propagated by the typesig module and also by the dataflow module. A lot of details have been fixed or updated. In particular the modules erl_types and erl_bif_types have been modified extensively. The version in vsn.mk has been updated to 2.7. The reason is a modification of #opaque{} in erl_types. Dialyzer seems to be about five percent slower than it used to be.
2013-04-08Fix minor error in natively compiled module listStavros Aronis
Even though dialyzer_typesig is the module doing most of the work, compiling it to native code twice will not make it faster than the rest. :-)

2013-02-19Native code compilation changesKostis Sagonas
Add more files to be compiled to native code and do the native code compilation in parallel if there are enough cores.
2012-08-21Add an undocumented option [--solver [v1 | v2]]Hans Bolinder
The original implementation of the type signature solver is called 'v1' and the newly introduced alternative implementation is called 'v2'. It is possible to run just the one of the solvers (in case there is a bug in for instance the v2 implementation) or both solvers ("--solver v1 --solver v2"). In the latter case an error is thrown if the outcome differ.

2011-01-20Add a --fullpath option to DialyzerKostis Sagonas
This change adds a --fullpath option to Dialyzer, which makes the warning messages contain the full path of the corresponding file. Original patch submitted by Magnus Henoch (legoscia) on 15/9/2010 and cooked to death in the 'pu' branch all this time. The patch was essentially correct and most of it has been used as is, but there have been some changes to make the code slightly prettier, avoid some code duplication, and add documentation to dialyzer's doc files and to its help message.
2010-11-30dialyzer: Add support for multiple PLTsMaria Christakis
This new feature is able to take multiple PLTs, merge them during the start of the analysis, and work from there. This works provided that the PLTs do not have a module with the same name appearing in more than one PLT. The PLTs are created in the usual way: dialyzer --build_plt --output_plt PLT_1 FILES_TO_INCLUDE ... dialyzer --build_plt --output_plt PLT_N FILES_TO_INCLUDE and then can be used in either of the following ways: dialyzer FILES_TO_ANALYZE --plts PLT_1 ... PLT_N or: dialyzer --plts PLT_1 ... PLT_N -- FILES_TO_ANALYZE (Note the -- delimiter in the second case)
2010-11-09dialyzer: Speed up analysis of nested list comprehensionsKostis Sagonas
Nested list comprehensions are translated into strongly connected funs but dialyzer ignored this. This meant that self-recursive analysis was normally executed for each fun and the whole fixpoint took some time to calculate. This patch adds every fun found in constraint generation to the SCC that is under analysis and then solves the SCC as a whole. Possible issues: - The returned dict contains more entries than usual. This triggered a bug in contract checking that is dealt with is this patch as well (dialyzer_contracts.erl). - As it's not easy to tell apart real fun SCCs from simple funs it performance might be hampered in the simple funs case. While doing these changes, also added and strengthened some specs. In addition, incorporated a modified patch by Ahmed Omar that fixes a bug in dialyzer_analysis_callgraph module that kept the files of only one selected directory in dialyzer's GUI.
