According to this article, DavidI is leaving EMBT to work for Evans Data.  Very interesting times, with Nick Hodges returning and DavidI leaving.

The Lengths we will go to for a Bug Fix

May 25th, 2016

For anyone using the Win64 Debugger in DX Seattle, you have probably experienced this little gem:

Debugger is Buggered

Debugger is Buggered

This seems to happen more frequently with multi-threaded applications, and unfortunately is not the only issue with the debugger.  Being unable to step into interfaced method calls which was reported on 12/1/2014 4:49:50 PM (541 days ago) is a real pain for 64 bit development.  Both issues are present in Seattle Update 1 and both are still unresolved with the release of Berlin.

I have been meaning to investigate how to use one of my support incidents to escalate RSP-14144, and apparently I am not alone in wondering how to get the priority changed for bugs to be addressed.  Keith Dopson has offered free meals, accommodations and shuttle service for EMBT to address RSP-13503 which surprisingly EMBT has not been able to duplicate. Kudos to you Keith! I hope it works out as we will all benefit.

Update - RSP-14144 was synced with the internal bug system yesterday. Apparently it is resolved in Berlin.

Not The Ideal Idera Experience

May 19th, 2016

My DX Seattle installation starting throwing access violations whenever a form was loaded into the IDE last week.  I had started to install Berlin on the same machine, so I wasn’t sure if that or some other installation had triggered this situation.  Having to bounce the IDE every 5 minutes was increasing my frustration level to the point I was about to nuke the whole machine, when I thought I would try a quick google to see if I could find the cause.  I found this thread, so I toggled on Tools - Options - Form Designer - Show Non-Visual Components and it worked!  I decided to search the bug reports only to find it has been fixed in Berlin.

I have an update subscription.  I was not notified that Berlin was released.  I found out from reading beginend.net posts well before I received a general marketing email on April 20th.  I wasn’t notified that a bug which might affect my product was fixed.  While I can subscribe to individual issues, I do not believe that I can get notifications for all bug fixes for my product edition.  Something Idera might want to look into…

A Case for YAGNI?

May 6th, 2016

I have worked with Delphi for a long time now (since D1), and am embarrassed to say that for the first time today, something occurred to me I have never thought of before.  I was waiting for DX Seattle to finish compiling a rather large project, or more accurately link it.  I was threading some legacy code and wanted to verify my changes could be compiled.  This is a very common usage scenario for Delphi.

It occurred to me that linking the EXE was a complete waste of time, and that link cycles are longer than normal because we are creating a detailed MAP file in our debug configuration.  I could eliminate this file, but we often use it with other tools.  I was thinking I should use Delphi’s Project - Syntax Check menu option instead.  So I tried it, and it ran through all the units in my source path that were referenced in the current project (directly or indirectly).  I thought to myself that the documentation which claims that “an efficient way to verify before compiling that a large project will build correctly” is not exactly accurate.  If it is so efficient, you would think it would be the preferred option to use, and it would have a menu short cut.

A more efficient way to to check for correct syntax is using Project -> Compile because it only re-compiles units that have changed since the last compilation.

So I was thinking, why wouldn’t the Syntax Check option do the same as a Compile, only checking changed files, or why wouldn’t the Compile avoid linking?  Most of the time linking is not necessary and could be performed when you hit F9 or Shift + F9.

The Parsing Problem

May 2nd, 2016

One of the major stumbling blocks Delphi tool developers have to overcome is the parsing problem.  Any add-in that allows re-factoring of code at any level must first parse it accurately enough to provide the additional functionality.  While Visual Studio has a VSIP (Visual Studio Integration Partners) program, EMBT has nothing to my knowledge.  They seem to discourage third party tool developers by not documenting the OpenTools API, or extending it to open up possibilities that are found in other IDEs from other vendors.

I don’t think this necessarily intentional, but the effect it has on the productivity of the IDE is enormous.  Up until the release of XE8 (IIRC) basic code navigation was missing from the IDE.  With the acquisition of Castalia the base product finally had a way to jump to method implementations short of using Ctrl+Shift+ Up/Dn Arrows after finding the method name.  By that time, most everyone was using a combination of GExperts and/or CnPack.

If you look at tools like ReSharper, or CodeRush for C# you will see just how far the Delphi IDE toolset is lagging behind.  Why?  Primarily because as the Object Pascal language has evolved under EMBT (kudos to them for doing so), there has not been a published language specification.  Third party tools reliant on their own parser have been left behind.  I’m not sure about those based on the Castalia parser derived from Martin Waldenburg’s parser.  I assume Castalia has also fallen behind since it’s last update was in October 2011.

Inevitably, some of these tools will no longer parse what is now valid Object Pascal.  I just ran into one today.  A tool that has been in the Delphi space since 2001.  I downloaded Peganza’s Pascal Analyzer and tried to run it on one of our projects to see what it could offer.  It failed in third party code that heavily uses generics (Spring for Delphi) in the Spring.Collections.MultiMaps unit line 49 of my version which reads:

fDictionaryEnumerator: IEnumerator<TPair<TKey, ICollection<TValue>>>;

with the error:

Syntax error type #123 (<) at Spring.Collections.MultiMaps row 49

Code re-factoring and analysis tools are critical for writing Enterprise level applications that must run 24×7.  I wish EMBT would open up the IDE so we could get rid of the spinning hourglass while code is parsed in the main IDE thread, and make the IDE more responsive.  While better in terms of not crashing with “Out of Memory” errors, DX Seattle is slower, still has leaks, and has issues of it’s own with 64 bit debugging.  An IDE needs to be stable, performant, and provide the developer with a rich set of tools for re-factoring their code.  There is much to be done on this front IMHO.  I think, formalizing the language and opening up the internal parser information would go a long way.  Even better, would be open source the IDE and let the community fix it :-)

Temporary Outage

April 22nd, 2016

You may have noticed that my blog has been off line for a while now.  Took me a couple weeks to find the time to rebuild my machine after a hard disk failure.  It’s still not 100%.  Images are not appearing with the blog articles for some reason.  I hope to have that resolved this weekend.

DX Seattle is Unstable with CnWizards

January 15th, 2016

I installed the latest CnPack’s Wizards 1.09.89 a couple days ago and DX Seattle suddenly seemed much slower, sometimes pausing for several seconds before presenting an hour glass and coming back to life.  A few times Windows actually detected it as not responding and prompted if I wanted to Debug or Close Delphi.

Today I uninstalled CnPack and DX Seattle is again responsive.  Too bad, I like a few of their add-ins.  Hopefully a subsequent release will resolve it.

Installers Lie

December 16th, 2015

At work I have an SSD which is only 220 GB so it is almost full almost all of the time.  Gone are the days of lean software deployments, and I am a hoarder when it comes to information.  As a result, I was attempting to install DX Seattle on my SSD and Install Aware told me I had sufficient space after unselecting various features.

After proceeding, Install Aware told me it does not have enough!

In the end I did manage to free enough space to get DX Seattle installed, although it was like playing Russian roulette.  I ended up removing vital components for SQL Server Management studio that I then had to repair.

A Pleasant Development

December 15th, 2015

I recently upgraded to DX Seattle which contains the long awaited (7+ releases) resolution for the “Out of Memory” issue.  I was pleased to see that DX Seattle is now Large Memory Address aware, in addition to using memory more efficiently according to Marco Cantu.

So far, after installing Update 1 with the Modern Style hot fix I have not experienced a single Out of Memory error.  As a result, we are upgrading our licenses for the first time in 3 years even though there is a big push to move the core products to .NET.  If only EMBT would have addressed this earlier, perhaps we wouldn’t be so motivated to move.

You ARE Paying for Bug Fixes - Do you like it?

May 7th, 2015

I got notified today again about the IDE memory consumption issue (RSP-9568) I continually encounter even in XE4, although it seems to be more severe in later versions.  The Atlassian graph is very telling.  It seems EMBT is not even treading water, let alone making progress addressing quality issues.

Issues: 239 created and 202 resolved

Issues: 239 created and 202 resolved

So without buying the latest release, when or more to the point if issues like the Out of Memory problem actually get fixed, do you really think you will get an update for free?  No you will have to buy the latest release with all the new bugs.

Effectively you are paying for the new bugs at the same time as you pay for the old ones to get fixed (if they do), not to mention the cost in terms of lost productivity, component upgrades, and installation time.

With .NET Native coming, soon Delphi will not even be able to claim to be king of the hill in terms of ease of deployment and fast startup times…we certainly cannot claim to have a superior IDE in terms of stability or productivity even it appears with the addition of Castalia.
