2018-01-10[observer] Improve performance for many links or monitorsSiri Hansen
When a process has many links and/or monitors, it could earlier take very long time to display the process information window. This is now improved by only showing a few links and monitors, and then an link named "more..." to expand the rest. Reading of the "Link list" from a crashdump is also improved.

2017-11-21Use base64 encoding in crash dumpsBjörn Gustavsson
This will reduce the size of crash dumps, especially if there are large binaries.
2017-11-21Correct parsing of sub binariesBjörn Gustavsson
Correct several problems parsing sub binaries. A sub binary would often be replaced with '#CDVNonexistingBinary'. When parsing a sub binary, we must scan ahead to find the definition of the refc or heap binary being referenced.
2017-11-20Generalize passing of options for decodingBjörn Gustavsson
The functions that decode Erlang terms from the crash dump file take a BinAddrAdj argument to adjust binary addresses in old crash dumps. To be able to add more decode options in the future, rename the argument to DecodeOpts and let it be a record.

2017-10-26[cdv] Check if dump version is newer than cdv can handleSiri Hansen
If the version of the given crash dump is newer than what crashdump_viewer is prepared to read, then crashdump_viewer will display an info dialog and then terminate. This is to allow major updates of the format of crash dumps.

2017-10-18Dump literals separately to avoid incomplete heap dataBjörn Gustavsson
When a literal was used from several processes, the literal would be dumped in only one of the processes. The other processes that referenced the literals would have incomplete heap data.
2017-10-18Implement dumping of maps in crash dumpsBjörn Gustavsson
Maps would be dumped as the atom 'undefined', which is not very informative.

2017-09-15cdv: Optimize reading of crashdump with many binariesSiri Hansen
Earlier, crashdump_viewer stored an index of all binaries in a gb_tree on startup. The binary index was also stored in the cdv_dump_index_table along with all other "=xxx" tags from the dump. The difference between the indices was that the ets table contained the addresses of the binaries as strings (the hex address found after the "=binary:" tag) and in the gb_tree this hex address was instead converted to its integer value. The index in the ets table was only used once - when creating the gb_tree. The gb_tree was used for all later looups (to map integer address to file position). This commit replaces the two storages with one new ets table, cdv_binary_index_table, using the integer value of the hex address as key, and the position in the crashdump file as value. In the case of many binaries, this makes the start of crashdump viewer faster (only one place to write), and the data usage smaller (hex address strings are no longer stored). And it avoids the gc of the gb_tree.
2017-09-13cdv: Find end of 'Last calls' sectionSiri Hansen
This is a bug fix: the end of the 'Last calls' section is meant to be an empty line, but in some situations this is not the case. This could cause the complete dump to be read and stored as 'Last calls', causing very unexpected behavior in the crashdump viewer. This commit adds a check for ": ", which indicates that a new heading has occured and thus the 'Last calls' section is completly read.

If a crashdump is truncated due to size limit reached, a new 'abort' tag with reason is added at the end of the crashdump. This reason is now displayed along with the truncated-warning.

Missing information
2014-05-27[cdv] Allow registered name as owner of timer in crashdumpSiri Hansen
crashdump_viewer would crash if the owner of a timer was specified as the process' regisered name. This has been corrected.
2014-03-25Fix crash in crashdump_viewer when node has multiple creationsSiri Hansen
A node to which we have references to multiple instances (creations) will have an information line in the crashdump like this: Creation: 1 2 ... This would earlier crash because crashdump_viewer would try to do list_to_integer on the value after "Creation: ". This is now corrected. This correction also helps the case when the emulator is debug compiled, since the line could then be Creation: 1 (refc=1)
2014-03-25Change spawn/1 + monitor/2 to spawn_monitor/1 to avoid deadlockSiri Hansen
crashdump_viewer:progress_pmap did sometimes hang since is spawned a process, then monitored it and waited for a specific DOWN message. When the process' work was very fast, it would exit before the call to monitor and the DOWN message would contain reason 'noproc' instead of the expected {pmap_done,Result}. By doing spawn_monitor/1 instead, the monitor is always set before the process exits so the deadlock is avoided.
