This allows the stack trace to be set when an error is received by the protocol, rather than appending it to the message. Now these errors will look no different than any other error and the stack trace will be reported in the same way.
One immediate benefit is that test.pl --vm-out --log-level-test=debug will work for tests that check expect log results. Previously, the test would error at the first check because the stack trace included in the message would not match the expected log output.
This will allow new links to be added in a future commit. The current implementation is driven by the links that already exist in the manifest, which would make the new use case more complex to implement.
Also, add a more helpful error when a tablespace link is specified.
"error list" makes it clearer that other errors may be reported. For example, if checksum-page is true in the manifest but no checksum-page-error list is provided then the error is in alignment, i.e. the file size is not a multiple of the page size, with allowances made for a valid-looking partial page at the end of the file.
It is still not possible to differentiate between alignment and page checksum errors in the output but this will be addressed in a future commit.
Azurite introduced a breaking change in 8f63964e to use automatically host-style URIs when the endpoint appears to be a multipart hostname.
This option allows the user to configure which style URI will be used, but changing the endpoint might cause breakage if Azurite decides to use a different style. Future changes to Azurite may also cause breakage.
The pack is both more compact and more efficient than a variant.
Also aggregate the page error info in the main process rather than in the filter to allow additional LSN filtering, to be added in a future commit.
The push and pop code was duplicated in four places, so centralize the code into pckTagStackPop() and pckTagStackPush().
Also create a default bottom item for the stack to avoid allocating a list if there will only ever be the default container, which is very common. This avoids the extra time and memory to allocate a list.
Rather than working directly with Buffer types, define a new Pack pseudo-type that represents a Buffer containing a pack. This makes it clearer that a pack is being stored and allows stronger typing.
The Pack type is more compact and flexible than the Variant type. The Pack type also allows binary data to be stored, which is useful for transferring the passphrase in the CipherBlock filter.
The primary purpose is to allow more (and more complex) result data to be returned efficiently from the PageChecksum filter. For now the PageChecksum filter still returns the original Variant. Converting the result data will be the subject of a future commit.
Also convert filter types to StringId.
Command-line help is now generated at build time so it does not need to be committed. This reduces churn on commits that add configuration and/or update the help.
Since churn is no longer an issue, help.auto.c is bzip2 compressed to save space in the binary.
The Perl config parser (Data.pm) has been moved to doc/lib since the Perl build path is no longer required.
Likewise doc/xml/reference.xml has been moved to src/build/help/help.xml since it is required at build time.
The newer version of valgrind helps with some arm64 issues that have been fixed since the architecture has become more popular. Also add the valgrind builds to the Vagrantfile and Dockerfile.
Move the CA cert install from the base container to the test container. This means the CA cert can be changed without rebuilding all the base containers.
The primary benefit is that objects can allocate memory for their struct with the context, which saves an additional allocation and makes it easier to read context/allocation dumps. Also, the memory context does not need to be stored with the object since it can be determined using the object pointer.
Object pointers cannot be moved, so this means whatever additional memory is allocated cannot be resized. That makes the additional memory ideal for object structs, but not so much for allocating a list that might change size.
Mem contexts can no longer be reused since they will probably be the wrong size so their memory is freed on memContextFree(). This still means fewer allocations and frees overall.
Interfaces still need to be freed by mem context so the old objMove() and objFree() have been preserved as objMoveContext() and objFreeContext(). This will be addressed in a future commit.
The prior limitations were based on using getopt_long() to parse command-line options, which required a static list of allowed options. Setting index max too high bloated the binary unacceptably. 45a4e80 replaced the functionality of getopt_long() but the static list remained.
Improve cfgParseOption() to use available option data and remove the need for a static list. This also allows the option deprecations to be represented more compactly.
Index max is still capped at 256 because a large enough index could cause parseOptionIdxValue() to run out of memory since it allocates a static list based on the highest index found. If that function were improved with a map of found index values then index max could be set to UINT64_MAX.
Note that deprecations no longer set an index max or define whether reset is valid. These were space-saving measures which are no longer required. This means that indexed deprecated options will also be valid up to 256 and always allow reset, but it doesn't seem worth additional code to limit this behavior.
cfgParseOptionId() is no longer needed because calling cfgParseOption() with .ignoreMissingIndex = true duplicates the functionality of cfgParseOptionId(). This leads to some simplification in the help code.
The certs are available in test/certificate so it makes more sense to use them there. In addition the container does not need to be rebuilt unless the CA cert changes.
contextParentIdx was introduced in 90709dfd to improve the performance of mem context frees. memContextMove() did not get the message, however, and continued to use a loop to find the mem context in the old parent.
Use contextParentIdx to find the mem context in the old parent to avoid a loop.
IMPORTANT NOTE: The log level for copied files in the backup/restore commands has been changed to detail. This makes the info log level less noisy but if these messages are required then set the log level for the backup/restore commands to detail.

The error was written to the client and then another command read. If the write did not fail then the loop would never exit.
Instead exit on any error that is not raised by the command handler as we can pretty safely assume this is an unrecoverable protocol error. The command handler might throw a protocol error itself, but this should be caught in the next read or write in the main loop.
If the buffer was not full at EOF then ioReadSmall() would get stuck in an infinite loop. Instead, return on EOF even if the buffer is not full.
This is not an issue in released versions since ioReadSmall() is not being used.
Also fix a comment typo.
The backup size was a bit off because it did not include any files (e.g. backup_label, WAL files) that were added to the manifest after the main copy. To fix this move the log message to the very end of the backup.
Add size/file total log message to restore since it did not exist before.
The storageInfoList() test was broken by 54c4eb0c when the remote was changed to use writeable storage. Since the test driver was being injected into the wrong location, new default storage was created and the test effectively did nothing but still "succeeded".
To prevent this type of regression, add checks to ensure the expected test driver is being used and the callback runs the expected number of times.
Cleanup all clients inherited from the parent process so they cannot be accidentally used to send messages to servers that do not belong to this process.
We need to do this carefully so that exit commands are not sent and processes are not terminated, so clear the mem context callback on each object before freeing it.
Options for other repos can cause conflicts and should never be used. Each remote can address exactly one repo or pg cluster.
Also fix an outdated comment.
This function was included in a header but not declared inline, so linker errors happened when the header was included into more than one file.
Because of the setjmp() in TRY_BEGIN() it can't be inlined so put it in a C file.
Also add some missing headers.
There have been intermittent failures on f33 (with coverage) but not on u16 (without coverage).
Reproducing this reliably has been very difficult, so just try increasing the timeouts. This is based on the observation that tests with coverage take longer than tests without, which may lead the f33 tests to fail if CI is running slower than usual.
This will not increase the runtime of the test unless there is an error.
If configure/make has been run in the src path it can conflict with tests, which may require different build options.
Also add a comment when rebuilding for code generation.
This file duplicated the command list that already exists in parse.auto.c.
Combine the data from config.auto.c into parse.auto.c and adjust the interface functions as needed. Quite a few were able to be moved to parse.c as static.
If the test path is inside the repo path then it can cause strange issues during testing because the entire repo path is duplicated into the test path so that all tests see a consistent view of the repo.
Another solution might be to pick a better test path name and exclude it from the rsync, but this fix at least addresses the immediate issue.
This was started in c5ae047e but did not include generation of parse.auto.c.
The parser has also been improved with better errors and multiple passes to reduce dependency on ordering and produce and cleaner output.
Option order resolution now includes cycle detection.
Remove strIdGenerate() since bldStrId() performs the same function without cluttering the core code. Since bldStrId() is intended to work in non-debug builds, move the validity checks for input strings out of the DEBUG block.
StringIds are generated as 5/6 bit, whichever is most efficient, for each option value. cfgOptionStrIdInternal() has been updated for this logic.
