Vince,
I guess this has its roots in long-ongoing discussions about the
anticipated disadvantages of image-based development in general. It
tries to explain that Smalltalk has mechanisms for recovering code after
an image crashes. It is not indicating that images do actually crash
more often than other development environments. It is more a remark
about the fact that of course even Smalltalk can crash and that there is
a mechanism (namely the changes file and changes browsers) for restoring
your code after a crash, even if you didn't file-out your code or didn't
push it to an external repository. Nothing more, nothing less.
So please don't read this as: "Since Pharo/Smalltalk isn't stable, we
had to xyz" - this is not the case. I've been using Smalltalk (mostly
not Pharo) for more than 25 years and I can only remember having a need
to recover source code maybe a hand full of times. In my favorite
Smalltalk (VA Smalltalk), I am almost 100% sure I never had this issue
because Envy is exactly the measure that is mentioned in the sentence
you cited.

Hi
This brings up some questions I have been meaning to ask for some time. The sentence
"When the Pharo image crashes (which will happen), there must be a way to
automatically recover from this crash." appears in the Enterprise Pharo Book.
Does this claim still apply? Is Pharo that unstable still?
If it is, what are the major causes in your own applications that crash it? I
have run a few small, local, experimental Teapot, Seaside and other Pharo
server apps and nothing crashed, but reading something like that makes me
nervous about public-facing server apps in Pharo.

I used to use daemontools. These days I use Docker.
