Normal storage is where all the +new data created during an XEmacs session is kept; see the following +section for information on normal storage. Pure storage is used for +certain data in the preloaded standard Lisp files--data that should +never change during actual use of XEmacs. + + Pure storage is allocated only while `temacs' is loading the +standard preloaded Lisp libraries. In the file `xemacs', it is marked +as read-only (on operating systems that permit this), so that the +memory space can be shared by all the XEmacs jobs running on the machine +at once. Pure storage is not expandable; a fixed amount is allocated +when XEmacs is compiled, and if that is not sufficient for the preloaded +libraries, `temacs' aborts with an error message. If that happens, you +must increase the compilation parameter `PURESIZE' using the +`--puresize' option to `configure'. This normally won't happen unless +you try to preload additional libraries or add features to the standard +ones. + + - Function: purecopy object + This function makes a copy of OBJECT in pure storage and returns + it. It copies strings by simply making a new string with the same + characters in pure storage. It recursively copies the contents of + vectors and cons cells. It does not make copies of other objects + such as symbols, but just returns them unchanged. It signals an + error if asked to copy markers. + + This function is a no-op except while XEmacs is being built and + dumped; it is usually called only in the file + `xemacs/lisp/prim/loaddefs.el', but a few packages call it just in + case you decide to preload them. + + - Variable: pure-bytes-used + The value of this variable is the number of bytes of pure storage + allocated so far. Typically, in a dumped XEmacs, this number is + very close to the total amount of pure storage available--if it + were not, we would preallocate less. + + - Variable: purify-flag + This variable determines whether `defun' should make a copy of the + function definition in pure storage. If it is non-`nil', then the + function definition is copied into pure storage. + + This flag is `t' while loading all of the basic functions for + building XEmacs initially (allowing those functions to be sharable + and non-collectible). Dumping XEmacs as an executable always + writes `nil' in this variable, regardless of the value it actually + has before and after dumping. + + You should not change this flag in a running XEmacs. + + +File: lispref.info, Node: Garbage Collection, Prev: Pure Storage, Up: Building XEmacs and Object Allocation + +Garbage Collection +================== + + When a program creates a list or the user defines a new function +(such as by loading a library), that data is placed in normal storage. +If normal storage runs low, then XEmacs asks the operating system to +allocate more memory in blocks of 2k bytes. Each block is used for one +type of Lisp object, so symbols, cons cells, markers, etc., are +segregated in distinct blocks in memory. (Vectors, long strings, +buffers and certain other editing types, which are fairly large, are +allocated in individual blocks, one per object, while small strings are +packed into blocks of 8k bytes. [More correctly, a string is allocated +in two sections: a fixed size chunk containing the length, list of +extents, etc.; and a chunk containing the actual characters in the +string. It is this latter chunk that is either allocated individually +or packed into 8k blocks. The fixed size chunk is packed into 2k +blocks, as for conses, markers, etc.]) + + It is quite common to use some storage for a while, then release it +by (for example) killing a buffer or deleting the last pointer to an +object. XEmacs provides a "garbage collector" to reclaim this +abandoned storage. (This name is traditional, but "garbage recycler" +might be a more intuitive metaphor for this facility.) + + The garbage collector operates by finding and marking all Lisp +objects that are still accessible to Lisp programs. To begin with, it +assumes all the symbols, their values and associated function +definitions, and any data presently on the stack, are accessible. Any +objects that can be reached indirectly through other accessible objects +are also accessible. + + When marking is finished, all objects still unmarked are garbage. No +matter what the Lisp program or the user does, it is impossible to refer +to them, since there is no longer a way to reach them. Their space +might as well be reused, since no one will miss them. The second +("sweep") phase of the garbage collector arranges to reuse them. + + The sweep phase puts unused cons cells onto a "free list" for future +allocation; likewise for symbols, markers, extents, events, floats, +compiled-function objects, and the fixed-size portion of strings. It +compacts the accessible small string-chars chunks so they occupy fewer +8k blocks; then it frees the other 8k blocks. Vectors, buffers, +windows, and other large objects are individually allocated and freed +using `malloc' and `free'. + + Common Lisp note: unlike other Lisps, XEmacs Lisp does not call + the garbage collector when the free list is empty. Instead, it + simply requests the operating system to allocate more storage, and + processing continues until `gc-cons-threshold' bytes have been + used. + + This means that you can make sure that the garbage collector will + not run during a certain portion of a Lisp program by calling the + garbage collector explicitly just before it (provided that portion + of the program does not use so much space as to force a second + garbage collection). + + - Command: garbage-collect + This command runs a garbage collection, and returns information on + the amount of space in use. (Garbage collection can also occur + spontaneously if you use more than `gc-cons-threshold' bytes of + Lisp data since the previous garbage collection.) + + `garbage-collect' returns a list containing the following + information: + + ((USED-CONSES .

(As you can see above, quite a lot of + information is provided.) + + - User Option: gc-cons-threshold + The value of this variable is the number of bytes of storage that + must be allocated for Lisp objects after one garbage collection in + order to trigger another garbage collection. A cons cell counts + as eight bytes, a string as one byte per character plus a few + bytes of overhead, and so on; space allocated to the contents of + buffers does not count. Note that the subsequent garbage + collection does not happen immediately when the threshold is + exhausted, but only the next time the Lisp evaluator is called. + + The initial threshold value is 500,000. If you specify a larger + value, garbage collection will happen less often. This reduces the + amount of time spent garbage collecting, but increases total + memory use. You may want to do this when running a program that + creates lots of Lisp data. + + You can make collections more frequent by specifying a smaller + value, down to 10,000. A value less than 10,000 will remain in + effect only until the subsequent garbage collection, at which time + `garbage-collect' will set the threshold back to 10,000. (This does + not apply if XEmacs was configured with `--debug'. Therefore, be + careful when setting `gc-cons-threshold' in that case!) + + - Function: memory-limit + This function returns the address of the last byte XEmacs has + allocated, divided by 1024. We divide the value by 1024 to make + sure it fits in a Lisp integer. + + You can use this to get a general idea of how your actions affect + the memory usage. + + - Variable: pre-gc-hook + This is a normal hook to be run just before each garbage + collection. Interrupts, garbage collection, and errors are + inhibited while this hook runs, so be extremely careful in what + you add here. In particular, avoid consing, and do not interact + with the user. + + - Variable: post-gc-hook + This is a normal hook to be run just after each garbage collection. + Interrupts, garbage collection, and errors are inhibited while + this hook runs, so be extremely careful in what you add here. In + particular, avoid consing, and do not interact with the user. + + - Variable: gc-message + This is a string to print to indicate that a garbage collection is + in progress. This is printed in the echo area. If the selected + frame is on a window system and `gc-pointer-glyph' specifies a + value (i.e. a pointer image instance) in the domain of the + selected frame, the mouse cursor will change instead of this + message being printed. + + - Glyph: gc-pointer-glyph + This holds the pointer glyph used to indicate that a garbage + collection is in progress. If the selected window is on a window + system and this glyph specifies a value (i.e. a pointer image + instance) in the domain of the selected window, the cursor will be + changed as specified during garbage collection. Otherwise, a + message will be printed in the echo area, as controlled by + `gc-message'. *Note Glyphs::. + + If XEmacs was configured with `--debug', you can set the following +two variables to get direct information about all the allocation that +is happening in a segment of Lisp code. + + - Variable: debug-allocation + If non-zero, print out information to stderr about all objects + allocated. + + - Variable: debug-allocation-backtrace + Length (in stack frames) of short backtrace printed out by + `debug-allocation'. + + +File: lispref.info, Node: Standard Errors, Next: Standard Buffer-Local Variables, Prev: Building XEmacs and Object Allocation, Up: Top + +Standard Errors +*************** + + Here is the complete list of the error symbols in standard Emacs, +grouped by concept. The list includes each symbol's message (on the +`error-message' property of the symbol) and a cross reference to a +description of how the error can occur. + + Each error symbol has an `error-conditions' property that is a list +of symbols. Normally this list includes the error symbol itself and +the symbol `error'. Occasionally it includes additional symbols, which +are intermediate classifications, narrower than `error' but broader +than a single error symbol.

It +can contain arbitrary text or graphics. It could be considered a +generalization of a toolbar, although toolbars are not currently +implemented using gutters. + + In XEmacs, a gutter can be displayed along any of the four edges +of the frame, and two or more different edges can be displaying +gutters simultaneously. The contents, thickness, and visibility of +the gutters can be controlled separately, and the values can +be per-buffer, per-frame, etc., using specifiers (@pxref{Specifiers}). + + Normally, there is one gutter displayed in a frame. Usually, this is +the default gutter, containing buffer tabs, but modes cab override this +and substitute their own gutter. This default gutter is usually +positioned along the top of the frame, but this can be changed using +@code{set-default-gutter-position}. + + Note that, for each of the gutter properties (contents, thickness, +and visibility), there is a separate specifier for each of the four +gutter positions (top, bottom, left, and right), and an additional +specifier for the ``default'' gutter, i.e. the gutter whose +position is controlled by @code{set-default-gutter-position}. The +way this works is that @code{set-default-gutter-position} arranges +things so that the appropriate position-specific specifiers for the +default position inherit from the corresponding default specifiers. +That way, if the position-specific specifier does not give a value +(which it usually doesn't), then the value from the default +specifier applies. If you want to control the default gutter, you +just change the default specifiers, and everything works. A package +such as VM that wants to put its own gutter in a different location +from the default just sets the position-specific specifiers, and if +the user sets the default gutter to the same position, it will just +not be visible. + +@node Gutter Descriptor Format, Specifying a Gutter, Gutter Intro, Gutter +@section Gutter Descriptor Format + + The contents of a gutter are specified using a @dfn{gutter descriptor}. +The format of a gutter descriptor is a list of @dfn{gutter button +descriptors}. Each gutter button descriptor is a vector in one of the +following formats: + +@itemize @bullet +@item +@code{[@var{glyph-list} @var{function} @var{enabled-p} @var{help}]} +@item +@code{[:style @var{2d-or-3d}]} +@item +@code{[:style @var{2d-or-3d} :size @var{width-or-height}]} +@item +@code{[:size @var{width-or-height} :style @var{2d-or-3d}]} +@end itemize + + Optionally, one of the gutter button descriptors may be @code{nil} +instead of a vector; this signifies the division between the gutter +buttons that are to be displayed flush-left, and the buttons to be +displayed flush-right. + + The first vector format above specifies a normal gutter button; +the others specify blank areas in the gutter. + + For the first vector format: + +@itemize @bullet +@item +@var{glyph-list} should be a list of one to six glyphs (as created by +@code{make-glyph}) or a symbol whose value is such a list. The first +glyph, which must be provided, is the glyph used to display the gutter +button when it is in the ``up'' (not pressed) state. The optional +second glyph is for displaying the button when it is in the ``down'' +(pressed) state. The optional third glyph is for when the button is +disabled. The last three glyphs are for displaying the button in the +``up'', ``down'', and ``disabled'' states, respectively, but are used +when the user has called for captioned gutter buttons (using +@code{gutter-buttons-captioned-p}). The function +@code{gutter-make-button-list} is useful in creating these glyph lists. + +@item +Even if you do not provide separate down-state and disabled-state +glyphs, the user will still get visual feedback to indicate which +state the button is in. Buttons in the up-state are displayed +with a shadowed border that gives a raised appearance to the +button. Buttons in the down-state are displayed with shadows that +give a recessed appearance. Buttons in the disabled state are +displayed with no shadows, giving a 2-d effect. + +@item +If some of the gutter glyphs are not provided, they inherit as follows: + +@example + UP: up + DOWN: down -> up + DISABLED: disabled -> up + CAP-UP: cap-up -> up + CAP-DOWN: cap-down -> cap-up -> down -> up + CAP-DISABLED: cap-disabled -> cap-up -> disabled -> up +@end example + +@item +The second element @var{function} is a function to be called when the +gutter button is activated (i.e. when the mouse is released over the +gutter button, if the press occurred in the gutter). It can be any +form accepted by @code{call-interactively}, since this is how it is +invoked. + +@item +The third element @var{enabled-p} specifies whether the gutter button +is enabled (disabled buttons do nothing when they are activated, and are +displayed differently; see above). It should be either a boolean or a +form that evaluates to a boolean. + +@item +The fourth element @var{help}, if non-@code{nil}, should be a string. +This string is displayed in the echo area when the mouse passes over the +gutter button. +@end itemize + + For the other vector formats (specifying blank areas of the gutter): + +@itemize @bullet +@item +@var{2d-or-3d} should be one of the symbols @code{2d} or @code{3d}, +indicating whether the area is displayed with shadows (giving it a +raised, 3-d appearance) or without shadows (giving it a flat +appearance). + +@item +@var{width-or-height} specifies the length, in pixels, of the blank +area. If omitted, it defaults to a device-specific value (8 pixels for +X devices). +@end itemize + +@defun gutter-make-button-list up &optional down disabled cap-up cap-down cap-disabled +This function calls @code{make-glyph} on each arg and returns a list of +the results. This is useful for setting the first argument of a gutter +button descriptor (typically, the result of this function is assigned +to a symbol, which is specified as the first argument of the gutter +button descriptor). +@end defun + +@defun check-gutter-button-syntax button &optional noerror +Verify the syntax of entry @var{button} in a gutter description list. +If you want to verify the syntax of a gutter description list as a +whole, use @code{check-valid-instantiator} with a specifier type of +@code{gutter}. +@end defun + +@node Specifying a Gutter, Other Gutter Variables, Gutter Descriptor Format, Gutter +@section Specifying a Gutter + + In order to specify the contents of a gutter, set one of the specifier +variables @code{default-gutter}, @code{top-gutter}, +@code{bottom-gutter}, @code{left-gutter}, or @code{right-gutter}. +These are specifiers, which means you set them with @code{set-specifier} +and query them with @code{specifier-specs} or @code{specifier-instance}. +You will get an error if you try to set them using @code{setq}.

The value in +the domain of a frame's selected window specifies the actual gutter +thickness or visibility that you will see in that frame. The value in +the domain of a frame itself specifies the gutter thickness or +visibility that is used in frame geometry calculations. + + Thus, for example, if you set the frame width to 80 characters and the +left gutter width for that frame to 68 pixels, then the frame will be +sized to fit 80 characters plus a 68-pixel left gutter. If you then +set the left gutter width to 0 for a particular buffer (or if that +buffer does not specify a left gutter or has a nil value specified for +@code{left-gutter-visible-p}), you will find that, when that buffer is +displayed in the selected window, the window will have a width of 86 or +87 characters -- the frame is sized for a 68-pixel left gutter but the +selected window specifies that the left gutter is not visible, so it is +expanded to take up the slack. + +@defvr Specifier gutter-buttons-captioned-p +Whether gutter buttons are captioned.

Supported PostgreSQL versions + This code was developed against libpq-6.5.3 and libpq-7.0-beta1. Earlier + versions may work. V7 support is more complete than V6.5 support. +1. Mule + Non-ASCII databases have been tested on both 6.5 and 7.0. +2. Asynchronous Operation + Starting with libpq-7.0, an asynchronous interface is offered. This + binding supports the asynchronous calls to a limited extent. Since the + XEmacs 21.2 core does not support a sensible interface to add managed but + unreadable (by XEmacs) file descriptors to the main select code, polling + is required to drive the asynchronous calls. XtAppAddInput would work + fine, but we want to be able to use the database when running strictly in + tty mode. +3. Completeness + Various calls have been deliberately not exported to Lisp. The + unexported calls are either left-over backwards compatibility code that + aren't needed, calls that cannot be implemented sensibly, or calls that + cannot be implemented safely. A list of all global functions in libpq + but not exported to Lisp is below. +4. Policy + This interface tries very hard to not set any policy towards how database + code in Emacs Lisp will be written. +5. Documentation + For full lisp programming documentation, see the XEmacs Lisp Reference + Manual. For PostgreSQL documentation, see the PostgreSQL distribution. + +TODO (in rough order of priority): +1. Asynchronous notifies need to be implemented to the extent they can be. +2.
